Context  More than 45 million individuals in the United States lack health insurance, potentially limiting their access to and use of appropriate health care services. Although the uninsured comprise a range of income levels, little attention has been directed at higher-income uninsured adults and their patterns of care. Objective  To examine whether having higher income attenuates the association between being uninsured and using fewer recommended health care services. Design, Setting, and Participants  Cross-sectional analysis of data from the 2002 Behavioral Risk Factor Surveillance System, drawn from a nationally representative sample of households. Participants were community-dwelling adults (n = 194 943; 50% women) aged 18 to 64 years in 2002. Main Outcome Measures  Self-reported use of screening for cervical, breast, and colorectal cancer; serum cholesterol screening and measurement, aspirin use, and tobacco cessation and weight loss counseling for cardiovascular risk reduction; and serum cholesterol and glycosylated hemoglobin measurement, eye and foot examination, and influenza and pneumococcal vaccination for diabetes management. Results  Among eligible adults, use of cancer prevention services ranged from 51% for colorectal cancer screening to 88% for cervical cancer screening, while use of cardiovascular risk reduction services ranged from 38% for weight loss counseling to 81% for aspirin use, and use of services for diabetes management ranged from 33% for pneumococcal vaccination to 88% for serum glycosylated hemoglobin measurement. In bivariate analyses, health insurance and annual household income were both strongly associated with use of nearly all examined health care services (P values <.01). Using multivariable analysis, increased annual household income did not significantly increase the likelihood of uninsured compared with insured adults receiving recommended health care services for cancer prevention, cardiovascular risk reduction, or diabetes management (P values >.05). Conclusions  Even among higher-income adults, lack of health care insurance was associated with significantly decreased use of recommended health care services; increased income did not attenuate the difference in use between uninsured and insured adults. Efforts to improve the use of recommended health care services among the uninsured should focus on patient education and expanding insurance eligibility for both lower-income and higher-income adults.   相似文献

Context  The prevalence and consequences of financial barriers to health care services and medications are not well documented for patients with an acute myocardial infarction (AMI). Objective  To measure the baseline prevalence of self-reported financial barriers to health care services or medication (as defined by avoidance due to cost) among individuals following AMI and their association with subsequent health care outcomes. Design, Setting, and Participants  The Prospective Registry Evaluating Myocardial Infarction: Event and Recovery (PREMIER), an observational, multicenter US study of patients with AMI over 12 months in 2498 individuals enrolled from January 2003 through June 2004. Main Outcome Measures  Health status symptoms (Seattle Angina Questionnaire [SAQ]), overall health status function (Short Form-12), and rehospitalization. Results  The prevalence of self-reported financial barriers to health care services or medication was 18.1% and 12.9%, respectively. Among individuals who reported financial barriers to health care services or medication, 68.9% and 68.5%, respectively, were insured. At 1-year follow-up, individuals with financial barriers to health care services were more likely to have lower SAQ quality-of-life score (77.9 vs 86.2; adjusted mean difference= –4.0; 95% confidence interval [CI], –6.3 to –1.8), and increased rates of all-cause rehospitalization (49.3% vs 38.1%; adjusted hazard ratio [HR], 1.3; 95% CI, 1.1-1.5) and cardiac rehospitalization (25.7% vs 17.7%; adjusted HR, 1.3; 95% CI, 1.0-1.6). At 1-year follow-up, individuals with financial barriers to medication were more likely to have angina (34.9% vs 17.9%; adjusted odds ratio, 1.55; 95% CI, 1.1-2.2), lower SAQ quality-of-life score (74.0 vs 86.1; adjusted mean difference = –7.6; 95% CI, –10.2 to –4.9), and increased rates of all-cause rehospitalization (57.0% vs 37.8%; risk-adjusted HR, 1.5; 95% CI, 1.2-1.8) and cardiac rehospitalization (33.7% vs 17.3%; adjusted HR, 1.7; 95% CI, 1.3-2.2). Conclusion  Financial barriers to health care services and medications are associated with worse recovery after AMI, manifested as more angina, poorer quality of life, and higher risk of rehospitalization.   相似文献

Context.— Communities differ in the way that medical care for medically indigent persons is organized and delivered, which is likely to result in differences across communities in the ability of uninsured persons to obtain medical care. Changes in the health care system, many of which are driven locally, may further exacerbate these differences. Objective.— To examine the extent of variation across US communities in the ability of uninsured persons to obtain medical care and the extent to which health status and other characteristics of the uninsured population account for these differences. Design.— Analysis of the 1996-1997 Community Tracking Study Household Survey. Setting.— A nationally representative sample of the US civilian, noninstitutionalized population residing in 60 randomly selected communities. Larger sample sizes were obtained for 12 of these communities, which were randomly selected to represent metropolitan areas in the United States with more than 200000 persons. Participants.— A total of 60446 individuals and 7200 uninsured persons. Main Outcome Measures.— The percentage of persons who either did not obtain needed medical care in the previous year or postponed receiving needed medical care in the previous year. Results.— Differences between communities with the highest percentage of uninsured persons reporting difficulty obtaining care and communities with the lowest percentage were more than 2-fold (41.4% vs 18.5%, P<.05). Little of the variation across communities is accounted for by differences in health status or sociodemographic characteristics of the uninsured population. The pattern of variation across communities in the ability of uninsured persons to obtain medical care is not correlated with variations in the ability of privately insured persons to obtain care (Pearson r, 0.04). Simulation results indicate that expanding private or public insurance coverage would not only increase the ability of uninsured persons to obtain medical care but would also reduce the variation across communities. Conclusions.— If people are uninsured, where they live is an important factor in determining the difficulty they have in obtaining care. This is likely to persist given that care for uninsured persons is driven largely by state and local policy, and health system changes are constraining clinicians' ability and willingness to serve uninsured persons in many parts of the country.   相似文献

Context  The prevalence of visual impairment in the US public has not been surveyed nationally in several decades. Objective  To estimate the number of US individuals aged 12 years or older who have impaired distance vision due to uncorrected refractive error. Design, Setting, and Participants  The National Health and Nutrition Examination Survey (NHANES), using a multistage probability sampling design, included a vision evaluation in a mobile examination center. Visual acuity data were obtained from 13 265 of 14 203 participants (93.4%) who visited the mobile examination center in 1999-2002. Visual impairment was defined as presenting distance visual acuity of 20/50 or worse in the better-seeing eye. Visual impairment due to uncorrected refractive error was defined as (presenting) visual impairment that improved, aided by automated refraction results, to 20/40 or better in the better-seeing eye. Main Outcome Measures  Presenting distance visual acuity (measured with usual corrective lenses, if any) and distance visual acuity after automated refraction. Results  Overall, 1190 study participants had visual impairment (weighted prevalence, 6.4%; 95% confidence interval [CI], 6.0%-6.8%), and of these, 83.3% could achieve good visual acuity with correction (95% CI, 80.9%-85.8%). Extrapolating these findings to the general US population, approximately 14 million individuals aged 12 years or older have visual impairment (defined as distance visual acuity of 20/50 or worse), and of these, more than 11 million individuals could have their vision improved to 20/40 or better with refractive correction. Conclusions  Visual impairment due to uncorrected refractive error is a common condition in the United States. Providing appropriate refractive correction to those individuals whose vision can be improved is an important public health endeavor with implications for safety and quality of life.   相似文献

Context  In contrast to the commercially insured population, the proportion of Medicaid beneficiaries enrolling in health maintenance organizations continues to increase. Objective  To compare quality of care within and between the Medicaid and commercial populations in 3 types of managed care plans: Medicaid-only plans (serving predominantly Medicaid enrollees), commercial-only plans (serving predominantly commercial enrollees), and Medicaid/commercial plans (serving substantial numbers of both types of enrollees). Design, Setting, and Participants  All 383 health plans that reported quality-of-care data to the National Committee for Quality Assurance for 2002 and 2003, including 204 commercial-only plans, 142 Medicaid/commercial plans (plans reported data for the Medicaid and commercial populations separately); and 37 Medicaid-only plans. Main Outcome Measures  Eleven quality indicators from the Healthcare Effectiveness Data and Information Set (HEDIS) applicable to the Medicaid population. Results  Among Medicaid enrollees, performance on the 11 measures observed in this study were comparable for Medicaid-only plans and Medicaid/commercial plans. Similarly, among commercial enrollees, there was virtually no difference in performance between health plans that served only the commercial population and those that also served the Medicaid population. Overall across all health plan types, the performance for the commercial population exceeded the performance for the Medicaid population on all measures except 1, ranging from a difference of 4.9% for controlling hypertension (58.4% for commercial vs 53.5% for Medicaid; P = .002) to 24.5% for rates of appropriate postpartum care (77.2% for commercial vs 52.7% for Medicaid; P = .001). Differences of similar magnitude were observed for commercial and Medicaid populations treated within the same health plan. Conclusions  Medicaid managed care enrollees receive lower-quality care than that received by commercial managed care enrollees. There were no differences in quality of care for the Medicaid population between Medicaid-only plans and commercial plans that also served the Medicaid population.   相似文献

Context  A shortage of data exists on medical care use by persons with attention-deficit/hyperactivity disorder (ADHD). Objective  To compare medical care use and costs among persons with and without ADHD. Design and Setting  Population-based cohort study conducted in Rochester, Minn. Subjects  All children born in 1976-1982 were followed up through 1995, using school and medical records to identify those with ADHD. The 4880 birth cohort members (mean age, 7.3 years) still residing in Rochester in 1987 were followed up in medical facility–linked billing databases until death, emigration, or December 31, 1995. Main Outcome Measures  Clinical diagnoses, likelihood and frequency of inpatient and outpatient hospitalizations, emergency department (ED) visits, and total medical costs (including ambulatory care), compared among individuals with and without ADHD. Results  Among the 4119 birth cohort members who remained in the area through 1995 (mean age, 15.3 years), 7.5% (n = 309) had met criteria for ADHD. Compared with persons without ADHD, those with ADHD were more likely to have diagnoses in multiple categories, including major injuries (59% vs 49%; P<.001) and asthma (22% vs 13%; P<.001). The proportion with any hospital inpatient, hospital outpatient, or ED admission was higher for persons with ADHD vs those without ADHD (26% vs 18% [P<.001], 41% vs 33% [P = .006], and 81% vs 74% [P = .005], respectively). The 9-year median costs for persons with ADHD compared with those without ADHD were more than double ($4306 vs $1944; P<.001), even for the subset with no hospital or ED admissions (eg, median 1987 costs, $128 vs $65; P<.001). The differences between individuals with and without ADHD were similar for males and females and across all age groups. Conclusion  In our cohort, compared with persons without ADHD, those with ADHD exhibited substantially greater use of medical care in multiple care delivery settings.   相似文献

Gaps in vaccine financing for underinsured children in the United States   总被引:2,自引:0,他引:2  
Context  The number of new vaccines recommended for children and adolescents has nearly doubled during the past 5 years, and the cost of fully vaccinating a child has increased dramatically in the past decade. Anecdotal reports from state policy makers and clinicians suggest that new gaps have arisen in financial coverage of vaccines for children who are underinsured (ie, have private insurance that does not cover all recommended vaccines). In 2000, approximately 14% of children were underinsured for vaccines in the United States. Objectives  To describe variation among states in the provision of new vaccines to underinsured children and to identify barriers to state purchase and distribution of new vaccines. Design, Setting, and Participants  A 2-phase mixed-methods study of state immunization program managers in the United States. The first phase included 1-hour qualitative telephone interviews conducted from November to December 2005 with 9 program managers chosen to represent different state vaccine financing policies. The second phase incorporated findings from phase 1 to develop a national telephone and paper-based survey of state immunization program managers that was conducted from January to June 2006. Main Outcome Measures  Percentage of states in which underinsured children are unable to receive publicly purchased vaccines in the private or public sectors. Results  Immunization program managers from 48 states (96%) participated in the study. Underinsured children were not eligible to receive publicly purchased meningococcal conjugate or pneumococcal conjugate vaccines in the private sector in 70% and 50% of states, respectively, or in the public sector in 40% and 17% of states, respectively. Due to limited financing for new vaccines, 10 states changed their policies for provision of publicly purchased vaccines between 2004 and early 2006 to restrict access to selected new vaccines for underinsured children. The most commonly cited barriers to implementation in underinsured children were lack of sufficient federal and state funding to purchase vaccines. Conclusions  The current vaccine financing system has resulted in gaps for underinsured children in the United States, many of whom are now unable to receive publicly purchased vaccines in either the private or public sectors. Additional strategies are needed to ensure financial coverage for all vaccines, particularly new vaccines, among this vulnerable population.   相似文献

Context  Health system changes may be affecting the ability of physicians to provide care with little or no compensation from patients who are uninsured and underinsured and may result in decreased access to physicians for uninsured persons. Objective  To examine the association between managed care and physicians' provision of charity care. Design  The 1996-1997 Community Tracking Study physician survey. Setting and Participants  A nationally representative sample of 10,881 physicians from 60 randomly selected communities. Main Outcome Measure  The number of hours in the month prior to the interview that the physician provided care for free or at reduced fees because of the financial need of the patient. Results  Overall, 77.3% of respondents provided an average of 10.3 hours of charity care per week. Physicians who derive at least 85% of their practice revenue from managed care plans were considerably less likely to provide charity care and spend fewer hours providing charity care than physicians with little involvement in managed care plans (P=.01). In addition, physicians who practice in areas with high managed care penetration provided fewer hours of charity care than physicians in other areas, regardless of their own level of involvement with managed care (P<.01). Differences in charity care provision were also shown for other important factors, including ownership of the practice and practice arrangements (more charity care occurred in solo and 2-physician practices; P<.01). Conclusion  Physicians involved with managed care plans and those who practice in areas with high managed care penetration tend to provide less charity care.   相似文献

Impact of malpractice reforms on the supply of physician services   总被引:1,自引:0,他引:1  
Kessler DP  Sage WM  Becker DJ 《JAMA》2005,293(21):2618-2625
Context  Proponents of restrictions on malpractice lawsuits claim that tort reform will improve access to medical care. Objective  To estimate the effects of changes in state malpractice law on the supply of physicians. Design  Differences-in-differences regression analysis that matched data on the number of physicians in each state between 1985 and 2001 from the American Medical Association’s Physician Masterfile with data on state tort laws and state demographic, political, population, and health care market characteristics. Main Outcome Measure  Effect on physician supply of "direct" malpractice reforms that reduce the size of awards (eg, caps on damages). Results  The adoption of "direct" malpractice reforms led to greater growth in the overall supply of physicians. Three years after adoption, direct reforms increased physician supply by 3.3%, controlling for fixed differences across states, population, states’ health care market and political characteristics, and other differences in malpractice law. Direct reforms had a larger effect on the supply of nongroup vs group physicians, on the supply of most (but not all) specialties with high malpractice insurance premiums, on states with high levels of managed care, and on supply through retirements and entries than through the propensity of physicians to move between states. Direct reforms had similar effects on less experienced and more experienced physicians. Conclusion  Tort reform increased physician supply. Further research is needed to determine whether reform-induced increases in physician supply benefited patients.   相似文献

Context  Depression is a common condition associated with significant morbidity in adolescents. Few depressed adolescents receive effective treatment for depression in primary care settings. Objective  To evaluate the effectiveness of a quality improvement intervention aimed at increasing access to evidence-based treatments for depression (particularly cognitive-behavior therapy and antidepressant medication), relative to usual care, among adolescents in primary care practices. Design, Setting, and Participants  Randomized controlled trial conducted between 1999 and 2003 enrolling 418 primary care patients with current depressive symptoms, aged 13 through 21 years, from 5 health care organizations purposively selected to include managed care, public sector, and academic medical center clinics in the United States. Intervention  Usual care (n = 207) or 6-month quality improvement intervention (n = 211) including expert leader teams at each site, care managers who supported primary care clinicians in evaluating and managing patients’ depression, training for care managers in manualized cognitive-behavior therapy for depression, and patient and clinician choice regarding treatment modality. Participating clinicians also received education regarding depression evaluation, management, and pharmacological and psychosocial treatment. Main Outcome Measures  Depressive symptoms assessed by Center for Epidemiological Studies-Depression Scale (CES-D) score. Secondary outcomes were mental health–related quality of life assessed by Mental Health Summary Score (MCS-12) and satisfaction with mental health care assessed using a 5-point scale. Results  Six months after baseline assessments, intervention patients, compared with usual care patients, reported significantly fewer depressive symptoms (mean [SD] CES-D scores, 19.0 [11.9] vs 21.4 [13.1]; P = .02), higher mental health–related quality of life (mean [SD] MCS-12 scores, 44.6 [11.3] vs 42.8 [12.9]; P = .03), and greater satisfaction with mental health care (mean [SD] scores, 3.8 [0.9] vs 3.5 [1.0]; P = .004). Intervention patients also reported significantly higher rates of mental health care (32.1% vs 17.2%, P<.001) and psychotherapy or counseling (32.0% vs 21.2%, P = .007). Conclusions  A 6-month quality improvement intervention aimed at improving access to evidence-based depression treatments through primary care was significantly more effective than usual care for depressed adolescents from diverse primary care practices. The greater uptake of counseling vs medication under the intervention reinforces the importance of practice interventions that include resources to enable evidence-based psychotherapy for depressed adolescents.   相似文献

Context  Uninsured near-elderly adults, particularly those with cardiovascular disease or diabetes, experience worse health outcomes than insured adults. However, the health benefits of providing insurance coverage for uninsured adults have not been clearly demonstrated.

Objective  To assess the effect of acquiring Medicare coverage on the health of previously uninsured adults.

Design and Setting  We conducted quasi-experimental analyses of longitudinal survey data from 1992 through 2004 from the nationally representative Health and Retirement Study. We compared changes in health trends reported by previously uninsured and insured adults after they acquired Medicare coverage at age 65 years.

Participants  Five thousand six adults who were continuously insured and 2227 adults who were persistently or intermittently uninsured from ages 55 to 64 years.

Main Outcome Measures  Differential changes in self-reported trends after age 65 years in general health, change in general health, mobility, agility, pain, depressive symptoms, and a summary measure of these 6 domains; and adverse cardiovascular outcomes (all trend changes reported in health scores per year).

Results  Compared with previously insured adults, previously uninsured adults reported significantly improved health trends after age 65 years for the summary measure (differential change in annual trend, +0.20; P = .002) and several component measures. Relative to previously insured adults with cardiovascular disease or diabetes, previously uninsured adults with these conditions reported significantly improved trends in summary health (differential change in annual trend, +0.26; P = .006), change in general health (+0.02; P = .03), mobility (+0.04; P = .05), agility (+0.08; P = .003), and adverse cardiovascular outcomes (–0.015; P = .02) but not in depressive symptoms (+0.04; P = .32). Previously uninsured adults without these conditions reported differential improvement in depressive symptoms (+0.08; P = .002) but not in summary health (+0.10; P = .17) or any other measure. By age 70 years, the expected difference in summary health between previously uninsured and insured adults with cardiovascular disease or diabetes was reduced by 50%.

Conclusion  In this study, acquisition of Medicare coverage was associated with improved trends in self-reported health for previously uninsured adults, particularly those with cardiovascular disease or diabetes.

Context  The adoption of pay-for-performance mechanisms for quality improvement is growing rapidly. Although there is intense interest in and optimism about pay-for-performance programs, there is little published research on pay-for-performance in health care. Objective  To evaluate the impact of a prototypical physician pay-for-performance program on quality of care. Design, Setting, and Participants  We evaluated a natural experiment with pay-for-performance using administrative reports of physician group quality from a large health plan for an intervention group (California physician groups) and a contemporaneous comparison group (Pacific Northwest physician groups). Quality improvement reports were included from October 2001 through April 2004 issued to approximately 300 large physician organizations. Main Outcome Measures  Three process measures of clinical quality: cervical cancer screening, mammography, and hemoglobin A1c testing. Results  Improvements in clinical quality scores were as follows: for cervical cancer screening, 5.3% for California vs 1.7% for Pacific Northwest; for mammography, 1.9% vs 0.2%; and for hemoglobin A1c, 2.1% vs 2.1%. Compared with physician groups in the Pacific Northwest, the California network demonstrated greater quality improvement after the pay-for-performance intervention only in cervical cancer screening (a 3.6% difference in improvement [P = .02]). In total, the plan awarded $3.4 million (27% of the amount set aside) in bonus payments between July 2003 and April 2004, the first year of the program. For all 3 measures, physician groups with baseline performance at or above the performance threshold for receipt of a bonus improved the least but garnered the largest share of the bonus payments. Conclusion  Paying clinicians to reach a common, fixed performance target may produce little gain in quality for the money spent and will largely reward those with higher performance at baseline.   相似文献

Context  Managed care has the potential to transform fundamentally the structure and functioning of the entire health care system, including the care provided to patients who are not enrolled in managed care plans. Objective  To determine whether increasing health maintenance organization (HMO) market share is associated with decreased expenditures for the care of patients covered by Medicare's traditional fee-for-service plan, a group cared for well outside the boundaries of managed care. Design and Setting  Data from the Health Care Financing Administration were used to compare expenditures for the care of Medicare fee-for-service beneficiaries for 802 market areas, representing the entire United States, for 1990 to 1994. These data were matched with data on system-wide (Medicare and non-Medicare) HMO market share in these areas. Patients  All fee-for-service Medicare beneficiaries (1990-1994) except for those with end-stage renal disease. Main Outcome Measure  Average fee-for-service expenditure per fee-for-service Medicare beneficiary by market area. Results  In a regression model, increases in system-wide HMO market share were associated with declines in both Part A and Part B fee-for-service expenditures per Medicare beneficiary (P<.001). Increases from 10% market share to 20% market share were associated with 2.0% decreases in Part A fee-for-service expenditures and 1.5% decreases in Part B fee-for-service expenditures. Conclusions  Managed care can have widespread effects on the health care system. Health care for individuals who are not covered by managed care organizations can be influenced by the presence of managed care. Lower expenditures in areas with high HMO market shares may indicate that traditional Medicare beneficiaries in areas with high market shares received fewer or less intensive services than traditional Medicare beneficiaries in other areas.   相似文献

Context  Beijing, China, experienced the world's largest outbreak of severe acute respiratory syndrome (SARS) beginning in March 2003, with the outbreak resolving rapidly, within 6 weeks of its peak in late April. Little is known about the control measures implemented during this outbreak. Objective  To describe and evaluate the measures undertaken to control the SARS outbreak. Design, Setting, and Participants  Data were reviewed from standardized surveillance forms from SARS cases (2521 probable cases) and their close contacts observed in Beijing between March 5, 2003, and May 29, 2003. Procedures implemented by health authorities were investigated through review of official documents and discussions with public health officials. Main Outcome Measures  Timeline of major control measures; number of cases and quarantined close contacts and attack rates, with changes in infection control measures, management, and triage of suspected cases; and time lag between illness onset and hospitalization with information dissemination. Results  Health care worker training in use of personal protective equipment and management of patients with SARS and establishing fever clinics and designated SARS wards in hospitals predated the steepest decline in cases. During the outbreak, 30 178 persons were quarantined. Among 2195 quarantined close contacts in 5 districts, the attack rate was 6.3% (95% confidence interval [CI], 5.3%-7.3%), with a range of 15.4% (95% CI, 11.5%-19.2%) among spouses to 0.36% (95% CI, 0%-0.77%) among work and school contacts. The attack rate among quarantined household members increased with age from 5.0% (95% CI, 0%-10.5%) in children younger than 10 years to 27.6% (95% CI, 18.2%-37.0%) in adults aged 60 to 69 years. Among almost 14 million people screened for fever at the airport, train stations, and roadside checkpoints, only 12 were found to have probable SARS. The national and municipal governments held 13 press conferences about SARS. The time lag between illness onset and hospitalization decreased from a median of 5 to 6 days on or before April 20, 2003, the day the outbreak was announced to the public, to 2 days after April 20 (P<.001). Conclusions  The rapid resolution of the SARS outbreak was multifactorial, involving improvements in management and triage in hospitals and communities of patients with suspected SARS and the dissemination of information to health care workers and the public.   相似文献

Context  Substance use disorders among physicians are important and persistent problems. Considerable debate exists over whether use of major opioids, especially among anesthesiologists, is associated with a higher relapse rate compared with alcohol and nonopioids. Moreover, the risk factors for relapse with current treatment and monitoring strategies are unknown. Objective  To test the hypothesis that chemically dependent health care professionals using a major opioid (eg, fentanyl, sufentanil, morphine, meperidine) as drug of choice are at higher risk of relapse. Design, Setting, and Participants  Retrospective cohort study of 292 health care professionals enrolled in the Washington Physicians Health Program, an independent posttreatment monitoring program, followed up between January 1, 1991, and December 31, 2001. Main Outcome Measure  Factors associated with relapse, defined as the resumption of substance use after initial diagnosis and completion of primary treatment for chemical dependency. Results  Twenty-five percent (74 of 292 individuals) had at least 1 relapse. A family history of a substance use disorder increased the risk of relapse (hazard ratio [HR], 2.29; 95% confidence interval [CI], 1.44-3.64). The use of a major opioid increased the risk of relapse significantly in the presence of a coexisting psychiatric disorder (HR, 5.79; 95% CI, 2.89-11.42) but not in the absence of a coexisting psychiatric disorder (HR, 0.85; 95% CI, 0.33-2.17). The presence of all 3 factors—major opioid use, dual diagnosis, and family history—markedly increased the risk of relapse (HR, 13.25; 95% CI, 5.22-33.59). The risk of subsequent relapses increased after the first relapse (HR, 1.69; 95% CI, 1.13-2.53). Conclusions  The risk of relapse with substance use was increased in health care professionals who used a major opioid or had a coexisting psychiatric illness or a family history of a substance use disorder. The presence of more than 1 of these risk factors and previous relapse further increased the likelihood of relapse. These observations should be considered in monitoring the recovery of health care professionals.   相似文献

Context  Illness and hospitalization often trigger functional decline among older persons. Home care services implemented for functional decline provide an opportunity to intervene to improve outcomes. Objective  To compare functional status and the likelihood of remaining at home for persons receiving restorative care vs usual home care. Design and Setting  Intervention using prospective individual matching conducted between November 1, 1998, and April 30, 2000. Six offices of a home care agency in Connecticut were used. One branch office served as the restorative care unit and the other 5 served as usual care offices. Participants  Patients receiving home care through the restorative care office who were 65 years or older; in receipt of Medicare-covered home care lasting at least 7 days; with absence of severe cognitive impairment; and not terminal, bedridden, or requiring total care were matched with patients from 1 of the usual care offices. The matching factors included age, sex, race, baseline self-care function, cognitive status, whether hospitalization preceded the home care episode, and date of the home care episode. Of the 712 eligible restorative care patients, 691 (97%) were matched with a usual care patient. Intervention  Restorative care, provided by the home care agency nursing, therapy, and home health aide staff, was based on principles from geriatric medicine, nursing, rehabilitation, and goal attainment. Main Outcome Measures  Remaining at home, functional status at completion of the home care episode, and duration and intensity of home care episode. Results  Compared with usual care, and after adjusting for baseline characteristics and other factors, restorative care was associated with a greater likelihood of remaining at home (82% vs 71%; odds ratio [OR], 1.99; 95% confidence interval [CI], 1.47-2.69) and a reduced likelihood of visiting an emergency department (10% vs 20%; OR, 0.44; 95% CI, 0.32-0.61). Home care episodes were shorter (mean [SD], 24.8 [26.8] days vs 34.3 [44.2] days; S = -17 821; P<.001). Restorative care patients had better mean (SD) scores than usual care patients in self-care (11.0 [2.1] vs 10.7 [2.5]; P = .07 after adjustment), home management (9.5 [2.9] vs 9.2 [3.0]; P = .05 after adjustment), and mobility (3.3 [0.8] vs 3.2 [0.9]; P = .02 after adjustment). Conclusions  This trial suggests that reorganizing the structure and goals of home care can enhance health outcomes of older patients without increasing health care utilization.   相似文献

Context  The increasing prevalence and associated sociodemographic disparities of morbid obesity are serious public health concerns. Bariatric surgical procedures provide greater and more durable weight reduction than behavioral and pharmacological interventions for morbid obesity. Objective  To examine trends for elective bariatric surgical procedures, patient characteristics, and in-hospital complications from 1998 to 2003 in the United States. Design, Setting, and Patients  The Nationwide Inpatient Sample was used to identify bariatric surgery admissions from 1998-2002 (with preliminary data for 12 states from 2003) using International Classification of Diseases, Ninth Revision, codes for foregut surgery with a confirmatory diagnosis of obesity or by diagnosis related group code for obesity surgery. Annual estimates and trends were determined for procedures, patient characteristics, and adjusted complication rates. Main Outcome Measures  Trends in bariatric surgical procedures, patient characteristics, and complications. Results  The estimated number of bariatric surgical procedures increased from 13 365 in 1998 to 72 177 in 2002 (P<.001). Based on preliminary state-level data (1998-2003), the number of bariatric surgical procedures is projected to be 102 794 in 2003. Gastric bypass procedures accounted for more than 80% of all bariatric surgical procedures. From 1998 to 2002, there were upward trends in the proportion of females (81% to 84%; P = .003), privately insured patients (75% to 83%; P = .001), patients from ZIP code areas with highest annual household income (32% to 60%, P<.001), and patients aged 50 to 64 years (15% to 24%; P<.001). Length of stay decreased from 4.5 days in 1998 to 3.3 days in 2002 (P<.001). The adjusted in-hospital mortality rate ranged from 0.1% to 0.2%. The rates of unexpected reoperations for surgical complications ranged from 6% to 9% and pulmonary complications ranged from 4% to 7%. Rates of other in-hospital complications were low. Conclusions  These findings suggest that use of bariatric surgical procedures increased substantially from 1998 to 2003, while rates of in-hospital complications were stable and length of stay decreased. However, disparities in the use of these procedures, with disproportionate and increasing use among women, those with private insurance, and those in wealthier ZIP code areas should be explored further.   相似文献

Context  Patients evaluated at emergency departments often present with nonemergency conditions that can be treated in other clinical settings. High-deductible health plans have been promoted as a means of reducing overutilization but could also be related to worse outcomes if patients defer necessary care. Objectives  To determine the relationship between transition to a high-deductible health plan and emergency department use for low- and high-severity conditions and to examine changes in subsequent hospitalizations. Design, Setting, and Participants  Analysis of emergency department visits and subsequent hospitalizations among 8724 individuals for 1 year before and after their employers mandated a switch from a traditional health maintenance organization plan to a high-deductible health plan, compared with 59 557 contemporaneous controls who remained in the traditional plan. All persons were aged 1 to 64 years and insured by a Massachusetts health plan between March 1, 2001, and June 30, 2005. Main Outcome Measures  Rates of first and repeat emergency department visits classified as low, indeterminate, or high severity during the baseline and follow-up periods, as well as rates of inpatient admission after emergency department visits. Results  Between the baseline and follow-up periods, emergency department visits among members who switched to high-deductible coverage decreased from 197.5 to 178.1 per 1000 members, while visits among controls remained at approximately 220 per 1000 (–10.0% adjusted difference in difference; 95% confidence interval [CI], –16.6% to –2.8%; P = .007). The high-deductible plan was not associated with a change in the rate of first visits occurring during the study period (–4.1% adjusted difference in difference; 95% CI, –11.8% to 4.3%). Repeat visits in the high-deductible group decreased from 334.6 to 255.3 visits per 1000 members and increased from 321.1 to 334.4 per 1000 members in controls (–24.9% difference in difference; 95% CI, –37.5% to –9.7%; P = .002). Low-severity repeat emergency department visits decreased in the high-deductible group from 142.5 to 92.1 per 1000 members and increased in controls from 128.0 to 132.5 visits per 1000 members (–36.4% adjusted difference in difference; 95% CI, –51.1% to –17.2%; P<.001), whereas a small decrease in high-severity visits in the high-deductible group could not be excluded. The percentage of patients admitted from the emergency department in the high-deductible group decreased from 11.8 % to 10.9% and increased from 11.9% to 13.6% among controls (–24.7% adjusted difference in difference; 95% CI, –41.0% to –3.9%; P = .02). Conclusions  Traditional health plan members who switched to high-deductible coverage visited the emergency department less frequently than controls, with reductions occurring primarily in repeat visits for conditions that were not classified as high severity, and had decreases in the rate of hospitalizations from the emergency department. Further research is needed to determine long-term health care utilization patterns under high-deductible coverage and to assess risks and benefits related to clinical outcomes.   相似文献

Context  On December 26, 2004, an undersea earthquake occurred off the northwestern coast of Sumatra, Indonesia. The tsunami that followed severely affected all 6 southwestern provinces of Thailand, where 5395 individuals died, 2991 were unaccounted for, and 8457 were injured. Objective  To assess the prevalence of symptoms of posttraumatic stress disorder (PTSD), anxiety, and depression among individuals residing in areas affected by the tsunami in southern Thailand as part of a public health emergency response and rapid assessment. Design, Setting, and Participants  A multistage, cluster, population-based mental health survey was conducted from February 15 to 22, 2005, of random samples of displaced (n = 371) and nondisplaced persons in Phang Nga province (n = 322) and nondisplaced persons in the provinces of Krabi and Phuket (n = 368). Data were collected using an interviewer-administered questionnaire on handheld computers. A surveillance follow-up survey of the displaced persons (n = 371) and nondisplaced persons (n = 322) in Phang Na was conducted in September 2005. Main Outcomes Measures  Medical Outcomes Study-36 Short-Form Health Survey SF-36 to assess self-perceived general health, bodily pain, and social and emotional functioning; the Harvard Trauma Questionnaire to assess tsunami-specific traumatic events; and the Hopkins Checklist-25 to detect symptoms of anxiety and depression. Results  Participation rates for displaced and nondisplaced persons in the rapid assessment survey were 69% and 58%, respectively. Symptoms of PTSD were reported by 12% of displaced and 7% of nondisplaced persons in Phang Nga and 3% of nondisplaced persons in Krabi and Phuket. Anxiety symptoms were reported by 37% of displaced and 30% of nondisplaced persons in Phang Nga and 22% of nondisplaced persons in Krabi and Phuket. Symptoms of depression were reported by 30% of displaced and 21% of nondisplaced persons in Phang Nga and 10% of nondisplaced persons in Krabi and Phuket. In multivariate analysis, loss of livelihood was independently and significantly associated with symptoms of all 3 mental health outcomes (PTSD, anxiety, and depression). In the 9-month follow-up surveillance survey of 270 (73%) displaced and 250 (80%) nondisplaced participants in Phang Nga, prevalence rates of symptoms of PTSD, anxiety, and depression among displaced persons decreased to 7%, 24.8%, and 16.7%, respectively, and among nondisplaced persons, prevalence rates decreased to 2.3%, 25.9%, and 14.3%, respectively. Conclusions  Among survivors of the tsunami in southern Thailand, elevated rates of symptoms of PTSD, anxiety, and depression were reported 8 weeks after the disaster, with higher rates for anxiety and depression than PTSD symptoms. Nine months after the disaster, the rates of those reporting these symptoms decreased but were still elevated. This information is important for directing, strengthening, and evaluating posttsunami mental health needs and interventions.   相似文献

Context  In June 2003, the US Food and Drug Administration licensed a trivalent live, attenuated influenza vaccine (LAIV-T) for intranasal administration to healthy persons 5 to 49 years of age. Although prelicensure testing involved 20 228 vaccinees, clinical trials were not of sufficient size to detect rare adverse events reliably. Objective  To identify adverse events reported following LAIV-T administration after licensure. Design, Setting, and Participants  All adverse events reported to the US Vaccine Adverse Event Reporting System (VAERS) during the 2003-2004 and the 2004-2005 influenza seasons. Main Outcome Measures  Numbers and proportions of reported adverse events and reporting rates of adverse events per 100 000 vaccinees. Results  Approximately 2 500 000 persons received LAIV-T during the first 2 postlicensure seasons. As of August 16, 2005, VAERS received 460 adverse event reports for vaccinations received from August 2003 through July 2005. No fatalities were reported. There were 7 reports of possible anaphylaxis, 2 reports of Guillain-Barré syndrome, 1 report of Bell palsy, and 8 reports of asthma exacerbation among individuals with a prior asthma history. Events in individuals for whom the vaccine was not indicated accounted for 73 reports (16%). Conclusions  Reports to VAERS in the first 2 seasons of LAIV-T use did not identify any unexpected serious risks with this vaccine when used according to approved indications. Like many vaccines and other medical products, LAIV-T may rarely cause anaphylaxis. Secondary transmission of the vaccine virus merits further investigation. Reports of asthma exacerbations in vaccinees with prior asthma history highlight the risks of vaccine use inconsistent with approved labeling.   相似文献
