Context: Studies of selected populations suggest that not all persons infected with human immunodeficiency virus (HIV) receive adequate care.Objective: To examine variations in the care received by a national sample representative of the adult US population infected with HIV.Design: Cohort study that consisted of 3 interviews from January 1996 to January 1998 conducted by the HIV Cost and Services Utilization Consortium.Patients and Setting: Multistage probability sample of 2864 respondents (68% of those targeted for sampling), who represent the 231400 persons at least 18 years old, with known HIV infection receiving medical care in the 48 contiguous United States in early 1996 in facilities other than emergency departments, the military, or prisons. The first follow-up consisted of 2466 respondents and the second had 2267 (65% of all surviving sampled subjects).Main Outcome Measures: Service utilization (<2 ambulatory visits, at least 1 emergency department visit that did not lead to hospitalization, at least 1 hospitalization) and medication utilization (receipt of antiretroviral therapy and prophylaxis against Pneumocystis carinii pneumonia).Results: Inadequate HIV care was commonly reported at the time of interviews conducted from early 1996 to early 1997 but declined to varying degrees by late 1997. Twenty-three percent of patients initially and 15% of patients subsequently had emergency department visits that did not lead to hospitalization, 30% initially and 26% subsequently of those who had CD4 cell counts below 0.20 x 10(9)/L did not receive P carinii pneumonia prophylaxis, and 41% initially and 15% subsequently of those who had CD4 cell counts below 0.50 x 10(9)/L did not receive antiretroviral therapy (protease inhibitor or nonnucleoside reverse transcriptase inhibitor). Inferior patterns of care were seen for many of these measures in blacks and Latinos compared with whites, the uninsured and Medicaid-insured compared with the privately insured, women compared with men, and other risk and/or exposure groups compared with men who had sex with men even after CD4 cell count adjustment. With multivariate adjustment, many differences remained statistically significant. Even by early 1998, fewer blacks, women, and uninsured and Medicaid-insured persons had started taking antiretroviral medication (CD4 cell count adjusted P values <.001 to <.005).Conclusions: Access to care improved from 1996 to 1998 but remained suboptimal. Blacks, Latinos, women, the uninsured, and Medicaid-insured all had less desirable patterns of care. Strategies to ensure optimal care for patients with HIV requires identifying the causes of deficiency and addressing these important shortcomings in care. [ABSTRACT FROM AUTHOR]

Objective: To develop and test a method for comparing the appropriateness of hysterectomy use in different health plans.Design: Retrospective cohort study.Setting: Seven managed care organizations.Patients: Random sample of all nonemergency, non-oncological hysterectomies performed in the seven managed care organizations over a 1-year period. Patients who were not continuously enrolled in a plan for 2 years prior to their hysterectomy were excluded.Main Outcome Measures: Proportion of women undergoing hysterectomy in each plan for inappropriate clinical reasons according to ratings derived from a panel of managed care physicians.Results: Overall, about 16% of women underwent hysterectomy for reasons judged to be clinically inappropriate. Only one plan had significantly more hysterectomies rated inappropriate compared with the group mean (27%, unadjusted). Adjusting for age and race did not affect the rankings of the plans and had little effect on the numeric results.Conclusion: The rates of inappropriate use of hysterectomies are similar to those for other procedures and vary to a small degree among health plans. This information may be useful to purchasers when they consider which health plans to offer their employees. [ABSTRACT FROM AUTHOR]

We used administrative (Part A Medicare) data to identify a representative sample of 1126 patients with congestive heart failure and 1150 with acute myocardial infarction in hospitals with significant unexpectedly high inpatient, age-sex-race-disease-specific death rates ("targeted") vs all other ("untargeted") hospitals in four states. Although death rates in targeted hospitals were 5.0 to 10.9 higher per 100 admissions than in untargeted hospitals, 56% to 82% of the excess could result from purely random variation. Differences in the quality of the process of care (based on a medical record review) could not explain the remaining statistically significant differences in mortality. Comparing targeted hospitals with subsets of untargeted ones, eg, those with lower than expected death rates, did not affect this conclusion. Severity of illness explained up to 2.8 excess deaths per 100 admissions for patients with myocardial infarction. Identifying hospitals that provide poor-quality care based on administrative data and single-year death rates is unlikely; targeting based on time periods greater than 1 year may be better.

Objective: To compare the appropriateness of coronary angiography and coronary artery bypass graft (CABG) use between the United States and Canada., Design: Retrospective randomized medical record review., Setting: All hospitals performing coronary angiography and/or CABG surgery in two Canadian provinces (Ontario and British Columbia); in New York State, 15 randomly selected hospitals that provide coronary angiography and 15 randomly selected hospitals that provide CABG surgery., Patients: All patients were randomly selected. For coronary angiography, 533 patients in Canada and 1333 patients in New York were selected; for CABG, 556 patients in Canada and 1336 patients in New York were selected., Main Outcome Measures: Percentage of patients in each country who had coronary angiography or CABG for necessary, appropriate, uncertain, or inappropriate indications as rated by criteria developed separately in each country and the complications of those procedures., Results: For coronary angiography, 9% of Canadian cases and 10% of New York cases were rated inappropriate using Canadian criteria compared with 5% and 4%, respectively, using US criteria. For CABG, 4% of Canadian cases and 6% of New York cases were rated inappropriate by Canadian criteria compared with 3% and 2%, respectively, using US criteria. A lower proportion of procedures were performed on persons aged 75 years or older in Canada than in New York for both coronary angiography (5% vs 11%; P < .001) and CABG (6% vs 14%; P < .001). Women were also represented in lower proportions among angiography cases in Canada than in New York (28% vs 35%; P = .023). Canadian patients with left main coronary disease waited significantly longer between angiography and CABG than did New York patients (P < .0001)., Conclusions: Rates of inappropriate use of cardiac procedures were low in Canada and New York, which suggests that the regionalization of cardiac procedures that characterizes both health care systems contributes to better clinical decision making. Differences in the use of cardiac procedures among the elderly in the two countries merits further comparative examination.

We studied the appropriateness of use of coronary angiography, carotid endarterectomy, and upper gastrointestinal tract endoscopy and its relationship to geographic variations in the rates of use of these procedures. We selected geographic areas of high, average, and low use of these procedures and randomly sampled Medicare beneficiaries who had received one of the procedures in 1981. We determined the indications for the procedures using a detailed review of medical records and used previously developed ratings of appropriateness to assign an appropriateness score to each case. Differences among sites in levels of appropriateness were small. For example, in the high-use site for coronary angiography, 72% of the procedures were appropriate, compared with 81% in the low-use site. Coronary angiography was performed 2.3 times as frequently in the high-use site compared with the low-use site. Under the conditions of this study, we did find significantly levels of inappropriate use: 17% of cases for coronary angiography, 32% for carotid endarterectomy, and 17% for upper gastrointestinal tract endoscopy. We conclude that differences in appropriateness cannot explain geographic variations in the use of these procedures.
