Are there Gender Differences in Diabetes Care Among Elderly Medicare Enrolled Veterans?

OBJECTIVE: To examine gender differences in diabetes care process measures and intermediate outcomes among veteran clinic users.
DESIGN: A retrospective cohort study using Veterans Health Administration (VHA) and Medicare files of VHA clinic users with diabetes. Diabetes care process measures were tests for hemoglobin A1c (HbA1c), low-density lipoprotein (LDL-C) values, and eye exams. Intermediate outcomes were HbA1c and LDL-C values below recommended thresholds. Chi-square tests and logistic regressions were used to assess gender differences.
PARTICIPANTS: Study population included 3,225 women and 231,922 men veterans with diabetes, enrolled in Medicare fee-for-service and alive at the end of fiscal year 2000.
RESULTS: Overall, there were no significant gender differences in HbA1c or LDL-C testing. However, women had higher rates in these process measures than men among the non-African American minorities. Women were more likely to have completed eye exams (odds ratio [OR]=1.11; 99% confidence interval [CI]=1.10, 1.23) but were less likely to have LDL-C under 130 mg/dL (OR=0.77; 99% CI=0.69, 0.87).
CONCLUSIONS: Among VHA patients with diabetes, clinically significant gender inequality was not apparent in most of diabetes care measures. However, there was evidence of better care among nonwhite and non-African American women than their male counterparts. Further research on interaction of race and gender on diabetes care is needed. This includes evaluation of integrated VHA women's health programs as well as cultural issues. Lower LDL-C control among women suggests areas of unmet needs for women and opportunities for future targeted quality improvement interventions at system and provider levels.

Simultaneous control of intermediate diabetes outcomes among veterans affairs primary care patients

BACKGROUND: Guidelines recommend tight control of hemoglobin A1c (HbA1c), low-density lipoprotein cholesterol (LDL-C), and blood pressure (BP) for patients with diabetes. The degree to which these intermediate outcomes are simultaneously controlled has not been extensively described. OBJECTIVE: Describe the degree of simultaneous control of HbA1c, LDL-C, and BP among Veterans Affairs (VA) diabetes patients defined by both VA and American Diabetes Association (ADA) guidelines. DESIGN: Cross-sectional cohort. PATIENTS: Eighty-thousand two hundred and seven VA diabetes patients receiving care between October 1999 and September 2000. MEASURMENTS: We defined simultaneous control of outcomes using 1997 VA Guidelines (in place in 2000) (HbA1c < 9.0%; LDL-C < 130 mg/dL; systolic BP < 140 mmHg; and diastolic BP < 90 mmHg) and 2004 ADA guidelines (HbA1c < 7.0%; LDL-C < 100 mg/dL; systolic BP < 130 mmHg; and diastolic BP < 80 mmHg). A patient is considered to have simultaneous control of the intermediate outcomes for a given definition if the average of measurements for each outcome was below the defined threshold during the study period. RESULTS: Using VA guidelines, 31% of patients had simultaneous control. Control levels of individual outcomes were: HbA1c (82%), LDL-C (77%), and BP (48%). Using ADA guidelines, 4% had simultaneous control. Control levels of individual outcomes were: HbA1c (36%), LDL-C (41%), and BP (23%). Associations between individual risk factors were weak. There was a modest association between LDL-C control and control of HbA1c (odds ratio [OR] 1.51; 95% confidence interval [CI] 1.44, 1.58). The association between LDL-C and BP control was clinically small (1.26; 1.21, 1.31), and there was an extremely small association between BP and HbA1c control (0.95; 0.92, 0.99). Logistic regression modeling indicates greater body mass index, African American or Hispanic race-ethnicity, and female gender were negatively associated with simultaneous control. CONCLUSION: While the proportion of patients who achieved minimal levels of control of HbA1c and LDL-C was high, these data indicate a low level of simultaneous control of HbA1c, LDL-C, and BP among patients with diabetes.     

Glycaemic control, disease duration and beta-cell function in patients with Type 2 diabetes in a Swedish community. Skaraborg Hypertension and Diabetes Project.

AIMS: To examine determinants for glycaemic control in primary care patients with Type 2 diabetes. METHODS: In a community-based surveillance of primary care patients with Type 2 diabetes, 190 men and 186 women were consecutively identified and examined for cardiovascular risk factors. Insulin resistance and beta-cell function were estimated using homeostasis model assessment (HOMA). Good glycaemic control was defined as HbA(1c) < 6.5%. RESULTS: Following adjustment for age and gender, HbA(1c) > or = 6.5% was associated with duration of diabetes (10.6 vs. 6.4 years, P < 0.001), lower levels of serum insulin (6.3 vs. 8.0 mU/l, P = 0.012), higher serum triglyceride levels (2.0 vs. 1.7 mmol/l, P = 0.002) and impairment of beta-cell function (HOMA index 19.5 vs. 45.8, P < 0.001). The association between HbA(1c) levels and duration remained with adjustment for age, gender, waist-hip ratio (WHR) and serum triglycerides (odds ratio (OR) for HbA(1c) > or = 6.5% by 5 years diabetes duration = 1.7; 95% confidence interval (CI) 1.4--2.1) but was lost following additional adjustment for beta-cell function (OR for HbA(1c) > or = 6.5% = 1.3; 95% CI 0.96-1.7). In a separate linear regression with beta-cell function as the dependent variable there was a significant association with HbA1c after adjustments for differences in age, gender, WHR, serum triglyceride levels and diabetes duration (P < 0.001). CONCLUSIONS: Increasing HbA1c by time was associated with declining beta-cell function.     

Communication factors in the follow-up of abnormal mammograms

OBJECTIVE: To identify the communication factors that are significantly associated with appropriate short-term follow-up of abnormal mammograms. DESIGN: Prospective longitudinal study involving medical record review and patient survey. SETTING: Ten academically affiliated ambulatory medical practices in the Boston metropolitan area. PARTICIPANTS: One hundred twenty-six women with abnormal mammograms requiring short-term (6 months) follow-up imaging. MEASUREMENTS: Proportion of women in the study who received appropriate follow-up care. RESULTS: Eighty-one (64%) of the women with abnormal mammograms requiring short-term follow-up imaging received the appropriate follow-up care. After adjusting for patients' age and insurance status, 2 communication factors were found to be independently associated with the delivery of appropriate follow-up care: 1). physicians' documentation of a follow-up plan in the medical record (adjusted odds ratio, 2.79; 95% confidence interval, 1.11 to 6.98; P =.029); and 2). patients' understanding of the need for follow-up (adjusted odds ratio, 3.86; 95% confidence interval, 1.50 to 9.96; P =.006). None of the patients' clinical or psychological characteristics were associated with the delivery of appropriate follow-up care. CONCLUSIONS: Follow-up care for women with abnormal mammograms requiring short-term follow-up imaging is suboptimal. Documentation of the follow-up plan by the physician and understanding of the follow-up plan by the patient are important factors that are correlated with the receipt of appropriate follow-up care for these women. Interventions designed to improve the quality of result follow-up in the outpatient setting should address these issues in patient-doctor communication.     

Health Status Among 28,000 Women Veterans

BACKGROUND: Male veterans receiving Veterans Health Administration (VA) care have worse health than men in the general population. Less is known about health status in women veteran VA patients, a rapidly growing population.
OBJECTIVE: To characterize health status of women (vs men) veteran VA patients across age cohorts, and assess gender differences in the effect of social support upon health status.
DESIGN AND PATIENTS: Data came from the national 1999 Large Health Survey of Veteran Enrollees (response rate 63%) and included 28,048 women and 651,811 men who used VA in the prior 3 years.
MEASUREMENTS: Dimensions of health status from validated Veterans Short Form-36 instrument; social support (married, living arrangement, have someone to take patient to the doctor).
RESULTS: In each age stratum (18 to 44, 45 to 64, and ≥65 years), Physical Component Summary (PCS) and Mental Component Summary (MCS) scores were clinically comparable by gender, except that for those aged ≥65, mean MCS was better for women than men (49.3 vs 45.9, P <.001). Patient gender had a clinically insignificant effect upon PCS and MCS after adjusting for age, race/ethnicity, and education. Women had lower levels of social support than men; in patients aged <65, being married or living with someone benefited MCS more in men than in women.
CONCLUSIONS: Women veteran VA patients have as heavy a burden of physical and mental illness as do men in VA, and are expected to require comparable intensity of health care services. Their ill health occurs in the context of poor social support, and varies by age.     

Do men benefit more than women from an interventional strategy in patients with unstable angina or non-ST-elevation myocardial infarction? The impact of gender in the RITA 3 trial.

AIMS: The RITA 3 trial randomized patients with non-ST-elevation myocardial infarction or unstable angina to strategies of early intervention (angiography followed by revascularization) or conservative care (ischaemia or symptom driven angiography). The aim of this analysis was to investigate the impact of gender on the effect of these two strategies. METHODS AND RESULTS: In total, 1810 patients (682 women and 1128 men) were randomized. The risk factor profile of women at presentation was markedly different to men. There was evidence that men benefited more from an early intervention strategy for death or non-fatal myocardial infarction at 1 year (adjusted odds ratios 0.63, 95% confidence interval 0.41-0.98 for men and 1.79, 95% confidence interval 0.95-3.35 for women; interaction p-value=0.007). Men who underwent the assigned angiogram were more likely to be put forward for coronary artery bypass surgery, even after allowing for differences in disease severity. CONCLUSION: An early intervention strategy resulted in a beneficial effect in men which was not seen in women although caution is needed in interpretation. Further research is needed to evaluate why women do not appear to benefit from early intervention and to identify treatments that improve the prognosis of women.     

Safely directing patients to appropriate levels of care: guideline-driven triage in the emergency service

STUDY OBJECTIVE: We sought to develop and validate standardized clinical criteria to identify patients presenting to the emergency department whose care may be safely deferred to a later date in a nonemergency setting. METHODS: Using a modified Delphi process, a 17-member multidisciplinary physician panel developed explicit, standardized, deferred-care criteria. In a prospective cohort design, emergency nurses at a tertiary care Veterans Administration (VA) Medical Center, using the criteria, screened 1,187 consecutive ambulatory adult patients presenting with abdominal pain, musculoskeletal symptoms, or respiratory infection symptoms. Patients meeting deferred-care criteria were offered the option of an appointment within 1 week in the ambulatory care clinic at the study site; all other patients were offered same-day care. As outcome measures, we assessed nonelective hospitalizations for related conditions occurring within 7 days of evaluation at our facility or any other VA facility within a 300-mile radius, and we assessed 30-day all-cause mortality. RESULTS: Two hundred twenty-six (19%) patients met screening criteria for deferred care. Patients meeting deferred-care criteria experienced zero (95% confidence interval, 0% to 1.2%) related nonelective VA hospitalizations within 7 days of evaluation, and none died within 30 days. By contrast, 68 (7%) of 961 (95% confidence interval, 5.5% to 8.9%) patients who did not meet deferred-care criteria were hospitalized nonelectively for related conditions, and 5 (0.5%) died. CONCLUSION: By using hospitalization and 30-day mortality as safety gauges, standardized clinical criteria can identify, at presentation, VA ED users who may be safely cared for at a later date in a nonemergency setting. These guidelines apply to a significant proportion of VA ED users with common ambulatory conditions. These criteria deserve testing in other ED settings.     

Gender differences in patients admitted with advanced decompensated heart failure

Broad population studies of patients with stable ambulatory heart failure have associated female gender with better age-adjusted survival. This study investigated whether there are gender-specific differences in clinical presentation, response to intensive medical therapy, and outcomes in patients admitted with advanced (cardiac index <2.4 L/min/m(2)) decompensated heart failure (ADHF). We reviewed 278 consecutive patients (age 54 +/- 12 years, cardiac index 1.7 +/- 0.4 L/kg/m(2), pulmonary capillary wedge pressure 26 +/- 9 mm Hg, serum creatinine 1.4 +/- 0.8 mg/dl) with ADHF treated with intensive medical therapy guided by pulmonary artery catheter in a dedicated heart failure intensive care unit from 2000 to 2006. Compared with men (n = 226), women (n = 52) had similar baseline characteristics with the exception of a higher prevalence of nonischemic cause. No differences in medical therapy on admission, during intensive medical therapy, or at discharge were observed. Intensive medical therapy was associated with significant hemodynamic improvement independent of gender. All-cause mortality and heart failure rehospitalization rates were similar between genders. However, adjusted for cause, women with ischemic cardiomyopathy had higher all-cause mortality rates (50% vs 37%, hazard ratio 1.95, 95% confidence interval 0.98 to 3.90, p = 0.05) and those with nonischemic cardiomyopathy had lower all-cause mortality rates (19% vs 40%, hazard ratio 0.40, 95% confidence interval 0.17 to 0.96, p = 0.01) than men. In conclusion, women presenting with ADHF had baseline characteristics and response to therapy similar to men. Overall outcomes were similar between men and women, although subgroup analysis suggested better survival for women with a nonischemic cause.     

Frequent use of the hospital emergency department is indicative of high use of other health care services

STUDY OBJECTIVE: We sought to determine the proportion of emergency department patients who frequently use the ED and to compare their frequency of use of other health care services at non-ED sites. METHODS: A computerized patient database covering all ambulatory visits and hospital admissions at all care facilities in the county of Stockholm, Sweden, was used. Frequent ED patients were defined as those making 4 or more visits in a 12-month period. RESULTS: Frequent users comprised 4% of total ED patients, accounting for 18% of the ED visits. The ED was the only source of ambulatory care for 13% of frequent versus 27% of rare ED users (1 ED visit). Primary care visits were made by 72% of frequent ED users versus 57% by rare ED visitors. The corresponding figures for hospital admission were 80% and 36%, respectively. Frequent ED visitors were also more likely to use other care facilities repeatedly: their odds ratio (adjusted for age and sex) was 3.43 (95% confidence interval [CI] 3.10 to 3.78) for 5 or more primary care visits and 29.98 (95% CI 26.33 to 34.15) for 5 or more hospital admissions. In addition, heavy users had an elevated mortality (standardized mortality ratio 1.55; 95% CI 1.26 to 1.90). CONCLUSION: High ED use patients are also high users of other health care services, presumably because they are sicker than average. A further indication of serious ill health is their higher than expected mortality. This knowledge might be helpful for care providers in their endeavors to find appropriate ways of meeting the needs of this vulnerable patient category.     

Using administrative data to track fall-related ambulatory care services in the Veterans Administration Healthcare system

BACKGROUND AND AIMS: The Veterans Administration (VA) Healthcare system, containing hospital and community-based outpatient clinics, provides the setting for the study. Summary data was obtained from the VA Ambulatory Events Database for fiscal years (FY) 1997-2001 and in-depth data for FY 2001. In FY 2001, the database included approximately 4 million unique patients with 60 million encounters. The purpose of this study was: 1) to quantify injuries and use of services associated with falls among the elderly treated in Veterans Administration (VA) ambulatory care settings using administrative data; 2) to compare fall-related services provided to elderly veterans with those provided to younger veterans. METHODS: Retrospective analysis of administrative data. This study describes the trends (FY 1997-2001) and patterns of fall-related ambulatory care encounters (FY 2001) in the VA Healthcare System. RESULTS: An approximately four-fold increase in both encounters and patients seen was observed in FY 1997-2001, largely paralleling the growth of VA ambulatory care services. More than two-thirds of the patients treated were found to be over the age of 65. Veterans over the age of 65 were found to be more likely to receive care in the non-urgent setting and had higher numbers of co-morbid conditions than younger veterans. While nearly half of the encounters occurred in the Emergency/Urgent Care setting, fall-related injuries led to services across a wide spectrum of medical and surgical providers/departments. CONCLUSIONS: This study represents the first attempt to use the VA Ambulatory Events Database to study fall-related services provided to elderly veterans. In view of the aging population served by the VA and the movement to provide increased services in the outpatient setting, this database provides an important resource for researchers and administrators interested in the prevention and treatment of fall-related injuries.     

Gender disparities in blood pressure control and cardiovascular care in a national sample of ambulatory care visits

The purpose of this study was to provide an analysis of gender-based disparities in hypertension and cardiovascular disease care in ambulatory practices across the United States. Using data from the 2005 National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey, we conducted a cross-sectional analysis of patient visits with their primary care providers and examined the association between gender and blood pressure control, use of any antihypertensive medication or initiation of new therapy for patients with uncontrolled hypertension, and receipt of recommended therapy for select cardiovascular conditions. Multivariable models were estimated to examine the association between gender and each outcome controlling for other variables. A total of 12 064 patient visits were identified (7786 women and 4278 men). Among patients with hypertension, women were less likely than men to meet blood pressure control targets (54.0% versus 58.7%; P<0.02). In multivariate analyses, women aged 65 to 80 years were less likely than men to have controlled hypertension (odds ratio: 0.62; 95% CI: 0.45 to 0.85). There was no association between gender and use of any antihypertensive medication or initiating a new therapy among patients with uncontrolled hypertension. In multivariate analyses, women were less likely than men to receive aspirin (odds ratio: 0.43; 95% CI: 0.27 to 0.67) and beta-blockers (odds ratio: 0.60; 95% CI: 0.36 to 0.99) for secondary prevention of cardiovascular disease. Our study highlights the persistent gender disparities in blood pressure control and cardiovascular disease management and also reveals the inadequate delivery of cardiovascular care to all patients.     

Postprandial blood glucose is a stronger predictor of cardiovascular events than fasting blood glucose in type 2 diabetes mellitus, particularly in women: lessons from the San Luigi Gonzaga Diabetes Study

OBJECTIVE: The influence of postprandial blood glucose on diabetes complications is intensively debated. We aimed to evaluate the predictive role of both fasting and postprandial blood glucose on cardiovascular events in type 2 diabetes and the influence of gender. METHODS: In a population of 529 (284 men and 245 women) consecutive type 2 diabetic patients attending our diabetes clinic, we evaluated the relationships, corrected for cardiovascular risk factors and type of treatment, between cardiovascular events in a 5-yr follow-up and baseline values of hemoglobin A1c (HbA1c) and blood glucose measured: 1) after an overnight fast, 2) after breakfast, 3) after lunch, and 4) before dinner. Continuous variables were categorized into tertiles. RESULTS: We recorded cardiovascular events in 77 subjects: 54 of 284 men (19%) and 23 of 245 women (9.4%). Univariate analysis indicated that cardiovascular events were associated with increasing age, longer diabetes duration, and higher HbA1c and fibrinogen in men, and higher systolic blood pressure, albumin excretion rate, HbA1c, and all blood glucose values in women. Smoking was more frequent in subjects with events. When all blood glucose values and HbA1c were introduced simultaneously in the models, only blood glucose after lunch predicted cardiovascular events, with hazard ratio of the third tertile vs. the first and the second tertiles greater in women (5.54; confidence interval, 1.45-21.20) than in men (2.12; confidence interval, 1.04-4.32; P < 0.01). CONCLUSIONS: Postprandial, but not fasting, blood glucose is an independent risk factor for cardiovascular events in type 2 diabetes, with a stronger predictive power in women than in men, suggesting that more attention should be paid to postprandial hyperglycemia, particularly in women.     

Gender and ethnic/racial disparities in health care utilization among older adults

OBJECTIVE: We examine the role of economic access in gender and ethnic/racial disparities in the use of health services among older adults. METHODS: Data from the 1993-1995 study on the Asset of Health Dynamics Among the Oldest Old (AHEAD) were used to investigate differences in the 2-year use of health services by gender and among non-Hispanic White versus minority (Hispanic and African American) ethnic/racial groups. Analyses account for predisposing factors, health needs, and economic access. RESULTS: African American men had fewer physician contacts; minority and non-Hispanic White women used fewer hospital or outpatient surgery services; minority men used less outpatient surgery; and Hispanic women were less likely to use nursing home care, compared with non-Hispanic White men, controlling for predisposing factors and measures of need. Although economic access was related to some medical utilization, it had little effect on gender/ethnic disparities for services covered by Medicare. However, economic access accounted for minority disparities in dental care, which is not covered by Medicare. DISCUSSION: Medicare plays a significant role in providing older women and minorities access to medical services. Significant gender and ethnic/racial disparities in use of medical services covered by Medicare were not accounted for by economic access among older adults with similar levels of health needs. Other cultural and attitudinal factors merit investigation to explain these gender/ethnic disparities.     

Effect of Health-Related Quality of Life on Women and Men’s Veterans Affairs (VA) Health Care Utilization and Mortality

Introduction Although women will account for almost 11% of veterans by 2040, we know little about their health and functioning, particularly compared to men. Objective To compare women and men veterans’ health-related quality of life (HRQOL) and VA health care utilization and to see if previously described associations between HRQOL, subsequent VA health care utilization, and mortality in male veterans would generalize to women veterans. Methods Prospective cohort study of all veterans who received medical care from an Upper Midwest Veterans Affairs facility between 10/1/96 and 3/31/98 and returned a mailed questionnaire. Results Women’s effective survey response rate was 52% (n = 1,500); men’s, 58% (n = 35,000). In the following year, 9% of women and 12% of men had at least one hospitalization. One percent of women and 3% of men died in the post-survey year. After adjustment, women’s HRQOL was higher than men’s; for every 10-point decrement in overall physical or mental functioning, women and men had similarly increased risk/odds of subsequently dying, being hospitalized at a VA facility, or making a VA outpatient stop. Among younger women and women who received VA care outside of the Twin City metro area, poorer overall mental or physical health functioning was associated with fewer primary care stops; among their male counterparts, it was associated with more primary care stops. Conclusion Compared to men, women veterans receiving VA health care in the upper Midwest catchment area had better HRQOL and used fewer health services. Although VA health care utilization was similar across gender after adjusting for HRQOL, poorer mental or physical health was associated with fewer primary care stops for selected subgroups of women.

Biology or bias: practice patterns and long-term outcomes for men and women with acute myocardial infarction

OBJECTIVES: The goal of our study was to examine how age and gender affect the use of coronary angiography and the intensity of cardiac follow-up care within the first year after acute myocardial infarction (AMI). Another objective was to evaluate the association of age, gender and treatment intensity with five-year survival after AMI. BACKGROUND: Utilization rates of specialized cardiac services inversely correlate with age. Gender-specific practice patterns may also vary with age in a manner similar to known age-gender survival differences after AMI. METHODS: Using linked population-based administrative data, we examined the association of age and gender with treatment intensity and long-term survival among 25,697 patients hospitalized with AMI in Ontario between April 1, 1992, and December 31, 1993. A Cox proportional hazards model was used to adjust for socioeconomic status, illness severity, attending physician specialty and admitting hospital characteristics. RESULTS: After adjusting for baseline differences, the relative rates of angiography and follow-up specialist care for women relative to men, respectively, fell 17.5% (95% confidence interval [CI], 13.6 to 21.3, p < 0.001) and 10.2% (95% CI, 7.1 to 13.2, p < 0.001) for every 10-year increase in age. Conversely, long-term AMI survival rates in women relative to men improved with increasing age, such that the relative survival in women rose 14.2% (95% CI, 10.1 to 17.5, p < 0.001) for every 10-year age increase. CONCLUSIONS: Gender differences in the intensity of invasive testing and follow-up care are strongly age-specific. While care becomes progressively less aggressive among older women relative to men, survival advantages track in the opposite direction, with older women clearly favored. These findings suggest that biology is likely to remain the main determinant of long-term survival after AMI for women.     

Relationship of gender,depression, and health care delivery with antiretroviral adherence in HIV-infected drug users

BACKGROUND: Antiretroviral adherence is worse in women than in men, and depression can influence medication adherence. OBJECTIVE: To evaluate the relationship of gender, depression, medical care, and mental health care to adherence in HIV-infected drug users. DESIGN: Retrospective cohort study. SETTING: New York State Medicaid program. PARTICIPANTS: One thousand eight hundred twenty-seven female and 3,246 male drug users on combination antiretroviral therapy for more than 2 months in 1997. MAIN MEASURES: A pharmacy-based measure of adherence was defined as > or =95% days covered by at least 2 prescribed antiretroviral drugs. Independent variables were: depression, regular drug treatment (> or =6 months), regular medical care (2+ and >35% of visits), HIV-focused care (2+ visits), psychiatric care (2+ visits), and antidepressant therapy. RESULTS: Women were less adherent than men (18% vs 25%, respectively,P <.001) and more likely to be diagnosed with depression (34% vs 29%). In persons with depression, the adjusted odds ratio (AOR) for adherence was greater for those with psychiatric care alone (AOR 1.52; 95% confidence interval [95% CI], 1.03 to 2.26) or combined with antidepressants (AOR 1.49; 95% CI, 1.04 to 2.15). In separate models by gender in persons with depression, psychiatric care plus antidepressants had a slightly stronger association with adherence in women (AOR 1.92; 95% CI, 1.00 to 3.68) than men (AOR, 1.26; 95% CI, 0.81 to 1.98). In drug users without depression, antidepressants alone were associated with greater adherence (AOR, 1.23; 95% CI, 1.02 to 1.49) with no difference by gender. Regular drug treatment was positively associated with adherence only in men. CONCLUSIONS: In this drug-using cohort, women had worse pharmacy-measured antiretroviral adherence than men. Mental health care was significantly associated with adherence in women, while regular drug treatment was positively associated with adherence in men.     

Influence of sexual orientation on diabetes management in US adults with diabetes

AimAlthough the risk of developing diabetes is high among US sexual minorities (SM) (lesbian, gay, bisexual), little is known about diabetes management in this population. We examined the impact of sexual orientation on current US diabetes management levels in a geographically diverse sample of people with diabetes (PWD).MethodAdult PWDs were identified from the 2015–2018 cross-sectional Behavioural Risk Factor Surveillance System surveys. We determined the unadjusted percentage and the adjusted odds ratios (OR) of noncompliance with American Diabetes Association (ADA) diabetes management measures (< 1 eye exam annually, < 1 foot exam annually, < 1 blood glucose check daily, < 2 A1C tests annually, no receipt of annual flu vaccination, never receiving pneumococcal vaccination, never taking a diabetes management course) in PWDs by SM status.ResultsUnadjusted analyses revealed a high level of noncompliance with diabetes management among SMs and especially for annual flu vaccination (40.1–52.3%) and diabetes management education (38.4–48.4%). Compared to heterosexuals, lesbian women were more noncompliant for most and bisexual men and bisexual women for all diabetes management measures. We observed that SMs had slightly higher adjusted levels of noncompliance than heterosexuals only for annual foot exams (OR: 1.09, 95% confidence interval (CI): 0.81–1.46) and diabetes management education (OR: 1.06, 95% CI: 0.81–1.41).ConclusionsHigh levels of noncompliance with ADA diabetes management guidelines in SM PWDs indicates a need for additional efforts to elucidate the factors that contribute to noncompliance in SMs, information that can be used to develop appropriate interventions to improve diabetes management for this population.     

Comparison of the quality of ambulatory care for fee-for-service and prepaid patients

OBJECTIVE: To determine whether the quality of care for common ambulatory conditions is adversely affected when physicians are provided with incentives to limit the use of health services. DESIGN: Retrospective cohort study over a 2-year period. SETTING: Four group practices that cared for both fee-for-service patients and prepaid patients within a network model health maintenance organization (HMO). PATIENTS: Equal numbers of prepaid (HMO) and fee-for-service patients were selected by randomly choosing medical records from each group practice: 246 patients with chronic uncomplicated hypertension and 250 women without chronic diseases who received preventive care. MAIN OUTCOME MEASURES: Adequate hypertension control was defined as a mean blood pressure of less than 150/90. Adequate preventive care was defined as the provision of blood pressure screening, colon cancer screening, breast cancer screening, and cervical cancer screening within guidelines recommended by the 1989 U.S. Preventive Services Task Force. Resource use was measured by the annual number of visits and tests. MAIN RESULTS: The adjusted relative odds of HMO patients having controlled hypertension, compared with fee-for-service patients, were 1.82 (95% CI, 1.02 to 3.27). The relative risks of HMO patients receiving preventive care within established guidelines were 1.19 (CI, 0.93 to 1.51) for colon cancer screening, 1.78 (CI, 1.11 to 2.84) for annual breast examinations, 1.75 (CI, 1.08 to 2.84) for biannual mammography, and 1.35 (CI, 1.13 to 1.60) for Papanicolaou smears every 3 years. Prepaid patients had visit rates that were 18% to 22% higher than those of fee-for-service patients. CONCLUSIONS: In the type of network model HMO we studied, the quality and quantity of ambulatory care for HMO patients was equal to or better than that for fee-for-service patients. In this setting, the incentives for physicians to limit resource use may be offset by lack of disincentives for HMO patients to seek care.
