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.

Differences in the use of procedures between women and men hospitalized for coronary heart disease.
BACKGROUND AND METHODS: Previous studies at individual hospitals have reported differences in the use of major diagnostic and therapeutic procedures for women and men with coronary heart disease. To assess whether these differences can be generalized, we performed retrospective analyses of coronary angiography and revascularization (coronary-artery bypass surgery or percutaneous transluminal coronary angioplasty) in women and men hospitalized for coronary heart disease in 1987, using abstract data on 49,623 discharges in Massachusetts and 33,159 discharges in Maryland. We used multiple logistic regression to estimate the adjusted odds of the use of a procedure, controlling for principal diagnosis, age, secondary diagnosis of congestive heart failure or diabetes mellitus, race, and insurance status. RESULTS: The adjusted odds of undergoing angiography were 28 percent and 15 percent higher for men than for women in Massachusetts and Maryland, respectively (95 percent confidence intervals for the odds ratios, 1.22 to 1.35 and 1.08 to 1.22). The respective adjusted odds of undergoing revascularization were 45 percent and 27 percent higher for men than for women (95 percent confidence intervals, 1.35 to 1.55 and 1.16 to 1.40). Because these differences could be related to differing thresholds for hospital admission, we performed a second analysis limited to patients with diagnosed acute myocardial infarction (11,865 discharges in Massachusetts and 6894 discharges in Maryland), a group in which all patients would be expected to receive hospital care. The male-to-female odds ratios in both states remained similar in magnitude and were statistically significant for angiography and revascularization. CONCLUSIONS: These findings demonstrate that women who are hospitalized for coronary heart disease undergo fewer major diagnostic and therapeutic procedures than men. These differences may represent appropriate levels of care for men and women, but it is also possible that they reflect underuse in women or overuse in men. Further study should assess the cause of these differences and their effect on patients' outcomes.

Delayed access to health care: risk factors, reasons, and consequences.
OBJECTIVE: To determine characteristics of patients reporting delays in care before hospitalization and the reasons for those delays. DESIGN: Survey; personal interviews. SETTING: Five hospitals in Massachusetts. PATIENTS: Subjects were drawn from a consecutive sample of all adult patients (excluding obstetrics or psychiatry patients) hospitalized during the first 6 months of 1987 as part of a larger study of hospital costs. For the current study, if patients were re-admitted, we included in our analysis only data on the first admission during the study period. We obtained usable survey data from 12,068 of 17,231 eligible patients. RESULTS: Delays in care were reported by 16% of patients. The odds of reporting delays in care among patients who were black, poor, uninsured, or without a regular physician were 40% to 80% greater than those for other patients (P less than 0.01). Most patients who reported delays thought that their problem was not serious (64%). Cost was an important factor in delaying care for patients in lower socioeconomic positions; the odds of delaying care because of cost for patients who were both poor and uninsured were 12 times greater than the odds for other patients (P less than 0.001). After controlling for diagnosis-related groups (DRGs) and severity, patients who reported delays had 9% longer hospital stays compared with others (P less than 0.001). CONCLUSIONS: Patients generally thought to be disadvantaged are at especially high risk for delaying care for conditions that eventually lead to hospitalization. Because these delays are associated with longer hospital stays and potentially poorer health outcomes, interventions that reduce delays seem especially important.

Health-related quality of life among patients undergoing percutaneous transluminal coronary angioplasty.
A randomized clinical trial was recently conducted to investigate whether a new antiplatelet agent could prevent restenosis in patients who had undergone percutaneous transluminal coronary artery angioplasty (PTCA). Approximately 1,200 patients were enrolled at 13 separate clinical sites. To assess the impact of this intervention on health-related quality of life, a patient questionnaire for telephone administration was developed. This questionnaire focused attention on several specific dimensions likely to be important in this patient population: physical well-being, perceived health, emotional well-being, home management, work, recreation, and social and sexual functioning. This paper describes the instrument that was used in this trial and reports on its psychometric [corrected] properties based on completed interviews with approximately 500 patients at study entry and 1 month after PTCA.

Trends in length of stay and rates of readmission in Massachusetts: implications for monitoring quality of care.
In this study, we examined lengths of stay and readmission rates for all Medicare patients discharged from Massachusetts acute care hospitals from October 1982 through September 1986. Using multivariate time series models, we controlled for case mix and assessed trends over time and the impact of prospective payment on lengths of stay and rates of readmission within 7, 14, and 30 days of discharge. We examined patterns for patients overall and for those admitted initially with one of several specific medical conditions or for a surgical procedure. Over the four years, lengths of stay decreased by 25% overall and by 12% to 38% for the individual conditions studied (all p less than .05). A small part of this decrease was associated with prospective payment. Overall readmission rates within 7 and 14 days increased by approximately 10% (p less than .05), although the increase was not statistically associated with prospective payment. Readmission rates for individual medical and surgical conditions were not significantly changed. Further study should assess whether the change in overall rates reflects lower quality care.

The association of payer with utilization of cardiac procedures in Massachusetts.
To investigate the importance of the payer in the utilization of in-hospital cardiac procedures, we examined the care of 37,994 patients with Medicaid, private insurance, or no insurance who were admitted to Massachusetts hospitals in 1985 with circulatory disorders or chest pain. Using logistic regression to control for demographic, clinical, and hospital factors, we found that the odds that privately insured patients received angiography were 80% higher than uninsured patients; the odds were 40% higher for bypass grafting and 28% higher for angioplasty. Medicaid patients experienced odds similar to those of uninsured patients for receiving angiography and bypass, but had 48% lower odds of receiving angioplasty. In addition, the odds for Medicaid patients were lower than for privately insured patients for all three cardiac procedures. These findings suggest that insurance status is associated with the utilization of cardiac procedures. Future studies should determine the implications these findings have for appropriateness and outcome and whether interventions might improve care.

Do the poor cost more? A multihospital study of patients' socioeconomic status and use of hospital resources.
There is controversy about whether hospitalized poor patients use more resources and whether hospitals that provide care for the poor therefore merit supplementary payment under per-case prospective payment systems. We previously reported that patients of low socioeconomic status with connective-tissue disease had longer hospital stays and higher costs than patients of higher socioeconomic status at a single hospital. To examine the generalizability of this phenomenon, we interviewed 16,908 (83 percent) of 20,278 consecutive adult patients (excluding obstetrical and psychiatric patients) admitted in 1987 to five Massachusetts hospitals, to obtain information on three direct measures of socioeconomic status (income, occupation, and education). We divided each measure into three strata. Thus, there were 15 comparisons--three measures of socioeconomic status applied to each of five hospitals. After excluding outliers and adjusting for diagnosis-related group (DRG), we found that the patients of the lowest socioeconomic status had hospital stays 3 to 30 percent longer than those of patients of higher status, the differences varying with the hospital and the indicator of socioeconomic status (P less than or equal to 0.05 for 11 of the 15 comparisons). Hospital charges were 1 to 18 percent higher for the patients of lowest socioeconomic status than for those of higher status (P less than or equal to 0.05 for 9 of 15 comparisons). When we adjusted for age, severity of illness, and DRG, the patients of lowest socioeconomic status had longer stays than those of higher status in 14 of 15 comparisons (P less than 0.05 for 7 of the 15) and higher charges in 13 of 15 comparisons (P less than 0.05 for 6 of the 15). The differences between patients of high and low status ranged up to 21 percent for length of stay and 13 percent for charges. Our findings suggest that hospitalized patients of lower socioeconomic status have longer stays and probably require more resources. Supplementary payments to hospitals for the treatment of poor patients merit further consideration.

Consultative geriatric assessment for ambulatory patients. A randomized trial in a health maintenance organization.
Previous studies have shown that comprehensive geriatric assessment and follow-up can improve the health of hospitalized elderly patients. To evaluate the effectiveness of consultative geriatric assessment and limited follow-up for ambulatory patients, we randomized 600 elderly patients who were enrolled in a health maintenance organization into three groups: (1) consultation by a geriatric assessment team, (2) consultation by a "second opinion" internist, and (3) only traditional health maintenance organization services (control patients). The geriatric assessment team identified previously unrecognized problems in 35% of patients and advised changes in medication regimens for more than 40%. Nevertheless, patients who received assessment achieved only a small benefit in cognitive function after 3 months, which was not sustained for 1 year. There was no difference among groups in other measures of health status. Consultative geriatric assessment with limited follow-up did not benefit most older ambulatory patients in a health maintenance organization; if such care can be used effectively for ambulatory patients, it will require either additional targeting or continuing care or both.

Older patients' health status and satisfaction with medical care in an HMO population.
Few studies have examined the relationship between older patients' satisfaction with medical care and their health status, and none of these investigations has been based at an HMO. To examine this question, data on 532 patients older than 70 years in an HMO were analyzed. Patients' reports of satisfaction with medical care were examined in relation to several dimensions of health status (based on self-reports, chart data, and physicians' ratings), their own sociodemographic characteristics, and characteristics of their primary physicians. Greater satisfaction was significantly associated with better self-rated health and physical function, less emotional distress, and more social activity but was not related to physicians' health ratings, number of diagnoses, or cognitive function. Mean levels of satisfaction were also significantly different for patients of different physicians but not appreciably related to patients' sociodemographic characteristics. When patient sociodemographic characteristics were controlled for, the relations of health status variables to satisfaction were essentially unchanged. It was concluded that the key issues to be resolved are whether better health leads to greater satisfaction or vice versa, and, in either case, whether the relations are mediated by factors relating to the patient's experience of medical care.

Effect of changing patterns of care and duration of survival on the cost of treating the acquired immunodeficiency syndrome (AIDS).
We performed a two-year cost of illness study of 240 AIDS patients (55 percent of all Massachusetts cases) diagnosed and treated at five hospitals from March 1984 through February 1986. Sociodemographic and clinical data as well as information on medical utilization were obtained from review of inpatient and outpatient hospital records. The yearly inpatient cost per patient decreased by 28 percent from $38,369 in year one to $27,714 in year two. These changes were related to shorter lengths of stay (from 20.6 days to 16.8 days per hospitalization, mean difference of 3.8 days, 95% CI of the difference -.2, 7.8), and less costly hospitalizations (from $12,463 to $9,957, mean difference of $2,506, 95% CI of the difference $135, $4,877). The probability of hospitalization, however, was similar in both years. These patterns of care were still evident after controlling for transmission category, race, site, mortality, insurance, age, gender, number and type of opportunistic diseases and time since diagnosis. Although the cost per patient per year decreased between years one and two, median survival increased by 70 percent (from 10 to 17 months). Hence overall estimated lifetime costs increased by 24 percent.

Teaching status and resource use for patients with acute myocardial infarction: a new look at the indirect costs of graduate medical education.
To investigate whether the process of graduate medical education increases costs in teaching hospitals by causing longer lengths of stay and greater resource use, we compared lengths of stay, hospital charges, and the use of cardiovascular procedures for patients with acute myocardial infarction admitted to the teaching and nonteaching services of a university-affiliated community hospital. After adjusting for severity of illness and demographic characteristics, patients on the teaching services had a mean length of stay that was shorter by 0.6 days (p = 0.04) and mean charges that were $2,060 lower (p = 0.15) than for patients on the nonteaching service. Patients on the teaching service also had 15 percent (95% CI: -26, -4) fewer cardiac catheterizations and 9 percent (-18, 0) fewer procedures for myocardial revascularization (angioplasty or cardiac bypass surgery). These findings suggest that graduate medical education per se may not directly increase the use of health care resources and that the cost differences between teaching and nonteaching hospitals may be largely a consequence of other factors. These factors may include epiphenomena of teaching such as a specialized organizational structure, specialized patient care services, and continuing medical education for the nursing and medical staffs. They may also include factors not related to teaching such as differences in patients' severity of illness and sociodemographic characteristics.

Racial inequalities in the use of procedures for patients with ischemic heart disease in Massachusetts.
To examine interracial differences in the utilization of coronary angiography, coronary artery bypass grafting, and coronary angioplasty for white and black patients, we examined all admissions for circulatory diseases or chest pain to Massachusetts hospitals in 1985. After controlling for age, sex, payer, income, primary diagnoses, and the number of secondary diagnoses, whites underwent significantly more angiography and coronary artery bypass grafting procedures. Whites also underwent more angioplasty procedures, but the difference was not statistically significant. Although utilization differences may reflect patient preference or different levels of disease severity and socioeconomic status not adequately accounted for, this study suggests that substantial racial inequalities exist in the use of procedures for patients hospitalized with coronary heart disease.

Multidimensionality of health status in an elderly population. Construct validity of a measurement battery.
Although health is generally accepted to be a multidimensional construct, the relationship among various domains has not been well defined. To understand this issue better we used principal components analysis to examine the relations among a set of health status measures gathered on 590 elderly members of a health maintenance organization (HMO). These included functional health, emotional health, social activity within and outside of the family, and cognitive functioning (all based on patient interview), physicians' ratings of patients' health, and chart-derived data on physiologic health. Support was obtained for the umbrella concept of "health" as well as for six subcomponents: functional health, emotional health, physiologic health, both kinds of social activity, and cognitive functioning. Patients' ratings of their overall physical and mental health were related to functional, physiologic, and emotional health factors, whereas physicians' ratings of overall physical and mental health were never related to the emotional health factor. This suggests that patients may hold a broader frame of reference in gauging overall health than physicians do.

Indirect costs for medical education. Is there a July phenomenon?
Medicare currently pays for "indirect costs" of medical education to support the higher costs of care in teaching hospitals. To investigate whether indirect costs are higher earlier in the training year when house officers might be less efficient--the "July phenomenon"--we compared utilization by 1251 patients hospitalized during July and August with 1338 patients hospitalized during April and May from 1982 through 1984 at Brigham and Women's Hospital, Boston, Mass. These included all patients in the 10 most prevalent medical and surgical diagnosis related groups. Using analysis of covariance to correct for age, sex, diagnosis related group, urgency of admission, temporal change, and mortality, we found no differences in length of stay, total charges, or categories of ancillary charges. These results suggest that there is no substantial increase in the cost of care early in the training year; there was no evidence of a "July phenomenon."
