Racial and ethnic differences in access to medical care in managed care plans

OBJECTIVE: To examine the extent to which access differences between racial/ethnic minorities and whites in managed care plans are greater than such differences in other types of health plans. DATA SOURCE: A nationally representative sample of 4,811 African American, 3,379 Hispanic, and 33,737 white nonelderly persons with public or private health insurance. STUDY DESIGN/DATA COLLECTION: A cross-sectional survey of households was conducted during 1996 and 1997. Commonly used measures of access to and utilization of medical care were constructed for individuals: (1) percentage of visits with a usual provider, (2) percentage with a regular provider, (3) visit with a physician in the past year, (4) hospital ER use, (5) last visit was to a specialist. PRINCIPAL FINDINGS: Fewer than 74 percent of Hispanics and African Americans had a regular provider compared to more than 78 percent of white Americans. Hispanics were least likely to have had their last doctor visit with a specialist (22 percent) compared to African Americans (26 percent) and whites (28 percent). Differences between ethnic/racial minorities and whites in managed care plans are similar to differences observed in non-managed care plans. Americans of all racial and ethnic backgrounds in managed care plans with gatekeeping are more likely to have a usual source of care, a regular provider, and lower use of specialists compared to persons in plans without gatekeeping. CONCLUSION: Although greater access to primary care was shown among African Americans and Hispanics in managed care plans, the extent of the disparities between racial/ethnic minorities and whites in managed care is similar to disparities in other types of health plans.     

Enrollment factors and preexisting medical conditions in a prepaid capitated plan. A comparison of university and nonuniversity clinic enrollees

Traditional wisdom suggests that academic medical centers attract sicker patients than nonacademic facilities, thereby incurring greater risk when caring for patients enrolled in prepaid health care plans. This study examines the affiliation of an academic medical center with a prepaid capitation-based medical plan in western Washington state and focuses on demographic characteristics, prior existing medical conditions, recent utilization, and factors affecting enrollee choice of health care plan, clinic, and physician. It was hypothesized that university clinic enrollees would differ from nonuniversity clinic enrollees with regard to many of these factors. A questionnaire was sent to a random sample of 400 university clinic enrollees and 759 enrollees in nonuniversity, private practice settings. The response rate was 56.1%. Results showed that, when compared with nonuniversity clinic enrollees in the same plan, university clinic enrollees were significantly younger and had more formal education. University clinic enrollees reported less health care utilization and expressed fewer strong preferences than nonuniversity clinic enrollees in choosing a health care plan, clinic, and physician. Based on this survey, there was no evidence that the academic medical center attracted sicker HMO enrollees than did nonuniversity clinics.     

Patient pain in primary care: factors that influence physician diagnosis

BACKGROUND: The accurate recognition of patient pain is a crucial, but sometimes difficult, task in medical care. This study explored factors related to the physician's diagnosis of pain in primary care patients. METHODS: New adult patients were prospectively randomized to care by primary care providers at a university medical center clinic. Study participants were interviewed prior to the initial visit, and their level of self-reported pain was measured with the Visual Analog Pain Scale and the Medical Outcomes Study Short Form-36. The medical encounter was videotaped in its entirety and later analyzed using the Davis Observation Code to characterize physician practice style. Patient satisfaction was measured immediately after the visit. A review of the medical record was used to assess physician recognition of patient pain. RESULTS: For all patients (N = 509), as the amount of pain increased, the percentage of patients having pain diagnosed by the physician also increased. Female patients reported a greater amount of pain than male patients. When women were in severe pain, they were more likely than men to have their pain accurately recognized by their physician. The correct diagnosis of pain was not significantly related to patient satisfaction. Physician practice styles emphasizing technically oriented activities and health behavior discussions were strongly predictive of the physician diagnosing patient pain. CONCLUSIONS: The diagnosis of pain is influenced by the severity of patient pain, patient gender, and physician practice style. If the routine use of pain assessment tools is found to be effective in improving physician recognition and treatment of patients' pain, then application of these tools in patient care settings should be encouraged.     

Evaluation of health care needs and patient satisfaction among hepatitis C patients treated at a hospital-based, viral hepatitis clinic

OBJECTIVE: To define self-reported hepatitis C knowledge, health care needs, and patient satisfaction in a representative cohort of hepatitis C virus (HCV)-infected adults treated at a university hospital-based viral hepatitis clinic in Canada. METHODS: A questionnaire package evaluating HCV knowledge, health care needs, and patient satisfaction was administered to 111 consecutive consenting HCV patients during their first and 10-month follow-up HCV clinic visits. RESULTS: At their first HCV clinic visit, 52% of patients rated their current HCV knowledge as "fair" or "poor". Patients identified HCV education, quality medical care, medication coverage, and psychological counselling as important HCV health care needs. Health care satisfaction outcome data at 10-month follow-up indicated that patients felt significantly better informed, more satisfied, and more actively involved in their HCV health care. CONCLUSION: A bio-psychosocial framework in which medical, psychological, educational, and social issues are addressed is desirable for optimal HCV health care.     

Managed Care, Access to Specialists, and Outcomes among Primary Care Patients with Pain

Objective. To determine whether managed care controls were associated with reduced access to specialists and worse outcomes among primary care patients with pain.
Data Sources/Study Setting. Patient, physician, and office manager questionnaires collected in the Seattle area in 1996–1997, plus data abstracted from patient records and health plans.
Study Design. A prospective cohort study of 2,275 adult patients with common pain problems recruited in the offices of 261 primary care physicians in Seattle.
Data Collection. Patients completed a waiting room questionnaire and follow-up surveys at the end of the first and sixth months to measure access to specialists and outcomes. Intensity of managed care controls measured by plan managed care index and benefit/cost-sharing indexes, office managed care index, physician compensation, financial incentives, and use of clinical guidelines.
Principal Findings. A financial withhold for referral was associated with a lower likelihood of referral to a physician specialist, a greater likelihood of seeing a specialist without referral, and a lower patient rating of care from the primary physician. Otherwise, patients in more managed offices and with greater out-of-network plan benefits had greater access to specialists. Patients with more versus less managed care had similar health outcomes, but patients in more managed offices had lower ratings of care provided by their primary physicians.
Conclusions. Increased managed care controls were generally not associated with reduced access to specialists and worse health outcomes for primary care patients with pain, but patients in more managed offices had lower ratings of care provided by their primary physicians.     

Does managed care restrictiveness affect the perceived quality of primary care? A report from ASPN. Ambulatory Sentinel Practice Network

BACKGROUND: The competitive managed care marketplace is causing increased restrictiveness in the structure of health plans. The effect of plan restrictiveness on the delivery of primary care is unknown. Our purpose was to examine the association of the organizational and financial restrictiveness of managed care plans with important elements of primary care, the patient-clinician relationship, and patient satisfaction. METHODS: We conducted a cross-sectional study of 15 member practices of the Ambulatory Sentinel Practice Network selected to represent diverse health care markets. Each practice completed a Managed Care Survey to characterize the degree of organizational and financial restrictiveness for each individual health care plan. A total of 199 managed care plans were characterized. Then, 1475 consecutive outpatients completed a patient survey that included: the Components of Primary Care Instrument as a measure of attributes of primary care; a measure of the amount of inconvenience involved with using the health care plan; and the Medical Outcomes Study Visit Rating Form for assessing patient satisfaction. RESULTS: Clinicians' reports of inconvenience were significantly associated (P < .001) with the financial and organizational restrictiveness scores of the plan. There was no association between plan restrictiveness and patient report of multiple aspects of the delivery of primary care or patient satisfaction with the visit. CONCLUSIONS: Plan restrictiveness is associated with greater perceived hassle for clinicians but not for patients. Plan restrictiveness seems to be creating great pressures for clinicians, but is not affecting patients' reports of the quality of important attributes of primary care or satisfaction with the visit. Physicians and their staffs appear to be buffering patients from the potentially negative effects of plan restrictiveness.     

The effect of private insurance access on the choice of GP/specialist and public/private provider in Spain

This paper sheds light into the investigation of differential patterns of utilisation of physician services by populations subgroups that is emerging in a number of studies. Using Spanish data from the National Health Survey of 1997 we try to explain the distinct role of the type of insurance on the choice between specialists and GPs and its intertwining with the choice between private and public providers. We estimate a two-stages probit to conclude that differences in insurance access is the main determinant of both, the choice of sector and the kind of physician contacted, giving rise to very different patterns of consumption of GP and specialist visits. People with only public insurance go 2.8 times to the GP per one time that they visit a specialist; individuals with duplicate coverage have a ratio of GP/specialist visits equal to 1.4 (the combination being public GP and private specialist) and people with only private insurance access actually have an 'inverted' pattern of visits: they contact specialists more often than GPs. Age, sex and health and public supply characteristics also have a distinct and interesting impact on these choices. Finally, equity concerns based on the implied assumption that specialists care is superior to general practitioner care are discussed.     

Physician retraining in primary care

Part of the health care provider restructuring consists of physician specialists retraining in primary care. The need is there, with additional pressures for qualified "gatekeepers" coming from the increase in managed care contracting.     

Continuity of primary care: to whom does it matter and when?

BACKGROUND: Inconsistent findings on the value of continuity of care can stem from variability in its importance to different subsets of patients. We therefore examined the association among patient and visit characteristics and extent to which the patient valued continuity of care (PVC). We hypothesized that continuity would be more important to patients who are older, sicker, and female, who have established a relationship with their physician, and whose visit addresses more complex problems. METHODS: A study of 4,454 consecutive outpatient visits to 138 community-based family physicians used a 3-item measure (alpha = 0.67) of PVC. The patient's report of (1) the adequacy of primary care for the visit and (2) satisfaction with the physician on that visit was assessed with multiple measures. Analyses examined the associations among PVC and patient-reported satisfaction with the physician and adequacy of the visit. RESULTS: Extremes of age, female sex, less education, Medicare and Medicaid insurance, number of chronic conditions and medications, number of visits to the practice, and worse self-reported health status were associated with higher value placed on continuity (P < .001 for all except sex, where P = .015). Patients who value continuity and did not see a regular physician rated adequacy of the visit lower (for 7 attributes of the visit) than those seeing their own physician. Satisfaction with the physician for the visit was greatest among patients who value continuity and saw their regular physician. CONCLUSIONS: Continuity of physician care is associated with more positive assessments of the visit and appears to be particularly important for more vulnerable patients. Health care systems and primary care practices should devote additional effort to maintaining a continuity relationship with these vulnerable patients.     

Technology and managed care: patient benefits of telemedicine in a rural health care network

Rural health providers have looked to telemedicine as a technology to reduce costs. However, virtual access to physicians and specialists may alter patients' demand for face-to-face physician access. We develop a model of service demand under managed care, and apply the model to a telemedicine application in rural Alaska. Provider-imposed delays and patient costs were highly significant predictors of patient contingent choices in a survey of ENT clinic patients. The results suggest that telemedicine increased estimated patient benefits by about $40 per visit, and reduced patients' loss from rationing of access to physicians by about 20%.     

Utilizing patient satisfaction surveys to prepare for Medicaid managed care

To prepare for Medicaid managed care, a community health center incorporated the business principle of continuous quality improvement, often used in the private sector to improve customer service, into its planning process. The initial endeavor was to create a patient satisfaction survey that was appropriate for the uniqueness of the community. The survey, taken monthly, resulted in both staff and patients making active improvements in the clinic environment. Staff showed more enthusiasm, and patients were more assertive in their attitudes toward the clinic. The empowerment of the patient to take ownership in the clinic will be coupled with the next step of the formalized plan, that of educating patients on the steps necessary to ensure that their Medicaid managed care facility will be the local community health center.     

A national study of problematic care experiences among Latinos with diabetes

Despite the large disease burden of diabetes, little is known about the care experiences of Latinos with diabetes across diverse primary care settings. This study compares problematic care experiences among Latinos with diabetes across usual care sites (community health centers [CHCs], private physician practices, or without a usual source of care), using a national sample of Latino diabetic patients (N=583). Nearly half of the respondents reported at least one problematic care experience during their last clinician visit. Compared with respondents treated primarily by private physicians, respondents receiving care in CHCs or without a usual source of care reported more problematic care experiences. However, patient health insurance coverage and acculturation accounted for the highest proportion of explainable differences in problematic care experiences between CHCs and private physician offices. Initiatives should clarify the extent to which the care experiences of Latino diabetics, particularly uninsured and less acculturated patients who tend to be cared for by CHCs, can be improved through clinician communication and patient self-management interventions.     

The impact of obesity on primary care visits

OBJECTIVE: To investigate the influence of patient obesity on primary care physician practice style. RESEARCH METHODS AND PROCEDURES: This was a randomized, prospective study of 509 patients assigned for care by 105 primary care resident physicians. Patient data collected included sociodemographic information, self-reported health status (Medical Outcomes Study Short Form-36), evaluation for depression (Beck Depression Index), and satisfaction. Height and weight were measured to calculate the BMI. Videotapes of the visits were analyzed using the Davis Observation Code (DOC). RESULTS: Regression equations were estimated relating obesity to visit length, each of the 20 individual DOC codes, and the six DOC Physician Practice Behavior Clusters, controlling for patient health status and sociodemographics. Obesity was not significantly associated with the length of the visit, but influenced what happened during the visit. Physicians spent less time educating obese patients about their health (p = 0.0062) and more time discussing exercise (p = 0.0075). Obesity was not related to discussions regarding nutrition. Physicians spent a greater portion of the visit on technical tasks when the patient was obese (p = 0.0528). Mean pre-visit general satisfaction for obese patients was significantly lower than for non-obese patients (p = 0.0069); however, there was no difference in post-visit patient satisfaction. DISCUSSION: Patient obesity impacts the medical visit. Further research can promote a greater understanding of the relationships between obese patients and their physicians.     

Managed Care and Gender Disparities in Problematic Health Care Experiences

Objective. To determine whether gender differences in reports of problematic health care experiences are associated with characteristics of managed care.
Data Sources. The 2002 Yale Consumer Experiences Survey ( N =5,000), a nationally representative sample of persons over 18 years of age with private health insurance, Interstudy Competitive Edge HMO Industry Report 2001, Area Resource File 2002, and the American Hospital Association Annual Survey of Hospitals 2002.
Study Design. Independent and interactive effects of gender and managed care on reports of problematic health care experiences were modeled using weighted multivariate logistic regression.
Principal Findings. Women were significantly more likely to report problems with their health care compared with men, even after controlling for gendered differences in expectations about medical care. Gender disparities in problem reporting were larger in plans that used certain managed care techniques, but smaller in plans using other methods. Some health plan managed care practices, including closed networks of providers and gatekeepers to specialty care, were associated with greater problem reporting among women, while others, such as requirements for primary care providers, were associated with greater problem reporting among men. Markets with higher HMO competition and penetration were associated with greater problem reporting among women, but reduced problem reporting among men. Women reported more problems in states that had enacted regulations governing access to OB/GYNs, while men reported more problems in states with regulations allowing specialists to act as primary care providers in health plans.
Conclusions. There are nontrivial gender disparities in reports of problematic health care experiences. The differential consequences of managed care at both the plan and market levels explain a portion of these gender disparities in problem reporting.     

Ambulatory medical care utilization estimates for 2005

OBJECTIVE: This report presents statistics on ambulatory care visits to physician offices, hospital outpatient departments (OPDs), and hospital emergency departments (EDs) in the United States in 2005. Ambulatory medical care utilization is described in terms of patient, practice, facility, and visit characteristics. METHODS: Data from the 2005 National Ambulatory Medical Care Survey (NAMCS) and the National Hospital Ambulatory Medical Care Survey (NHAMCS) were combined to produce averaged annual estimates of ambulatory medical care utilization. RESULTS: Patients in the United States made an estimated 1.2 billion visits to physician offices and hospital OPDs and EDs, a rate of 4.0 visits per person annually. Between 1995 and 2005, population visit rates increased by about 20% in primary care offices, surgical care offices, and OPDs; 37% in medical specialty offices; and 7% in EDs. The aging of the population has contributed to increased volume of visits because older patients have higher visit rates. Visits by patients 40-59 years of age represented about 28.5 percent in 2005, compared with 23.9 percent in 1995. Black persons had higher visit rates than white persons to hospital OPDs and EDs, but lower visit rates to office-based primary care and to surgical and medical specialists. In the ED, the visit rate for patients with no insurance was about twice that of those with private insurance; whereas for all types of office-based care, the visit rates were higher for privately insured persons than for uninsured persons. About 29.4 percent of all ambulatory care visits were for chronic diseases and 25.2 percent were for preventive care, including checkups, prenatal care, and postsurgical care. The leading treatment provided at ambulatory care visits was medicinal with 71.3 percent of all visits having one or more medications prescribed, up by 10% since 1995 when encounters with drug therapy represented 64.9 percent of all visits. In 2005, 2.4 billion medications were prescribed or administered at these visits.     

Physician and plan effects on satisfaction of Medicaid managed care patients with their health care and providers

As many Medicaid patients move into managed care, it is important that physicians competing to serve these patients understand the factors that lead to patient satisfaction. This study uses survey data from 7,313 Oregon Medicaid managed care patients to create a model describing how provider effects and health plan effects relate to patients' satisfaction with their medical care and provider. Path analysis was used to test the explanatory power and strength of relationships in the model. Perceived technical and interpersonal physician quality and health plan rating were most strongly linked with these patients' satisfaction with their care and provider.     

Effect of a gatekeeper plan on health services use and charges: a randomized trial.

A randomized trial was conducted to determine the effectiveness of a health care plan which uses physicians as gatekeepers to control health services use and charges. New enrollees in United Healthcare (UHC), an independent practice association, were randomly assigned to the standard UHC plan requiring a gatekeeper, or to an alternate plan with equal benefits but without a gatekeeper. Individuals in both plans were similar in demographic characteristics, perceived health status, and other health insurance coverage. The gatekeeper plan had 6 percent lower total charges per enrollee than the plan without a gatekeeper. There were minor differences in hospital use and charges. Ambulatory charges were $21 lower per person per year in the plan with a gatekeeper (95% CI = -39.9, -2.1) and these were due to .3 fewer visits to specialists (95% CI = -0.50, -0.10). We conclude that a health plan which incorporates incentives and penalties for physicians to act as gatekeepers can reduce the cost of ambulatory services by limiting specialist visits.     

Time allocation in primary care office visits

OBJECTIVES: To use an innovative videotape analysis method to examine how clinic time was spent during elderly patients' visits to primary care physicians. Secondary objectives were to identify the factors that influence time allocations. DATA SOURCES: A convenience sample of 392 videotapes of routine office visits conducted between 1998 and 2000 from multiple primary care practices in the United States, supplemented by patient and physician surveys. RESEARCH DESIGN: Videotaped visits were examined for visit length and time devoted to specific topics--a novel approach to study time allocation. A survival analysis model analyzed the effects of patient, physician, and physician practice setting on how clinic time was spent. PRINCIPAL FINDINGS: Very limited amount of time was dedicated to specific topics in office visits. The median visit length was 15.7 minutes covering a median of six topics. About 5 minutes were spent on the longest topic whereas the remaining topics each received 1.1 minutes. While time spent by patient and physician on a topic responded to many factors, length of the visit overall varied little even when contents of visits varied widely. Macro factors associated with each site had more influence on visit and topic length than the nature of the problem patients presented. CONCLUSIONS: Many topics compete for visit time, resulting in small amount of time being spent on each topic. A highly regimented schedule might interfere with having sufficient time for patients with complex or multiple problems. Efforts to improve the quality of care need to recognize the time pressure on both patients and physicians, the effects of financial incentives, and the time costs of improving patient-physician interactions.
