30-day survival and rehospitalization for stroke patients according to physician specialty.

BACKGROUND AND PURPOSE: Stroke patients appear to have improved outcomes when cared for by neurologists, but the mechanism by which improved outcome is achieved is unclear. This study compares 30-day cause-specific rehospitalization, 30-day mortality, and specific processes of care for patients treated by a neurologist only, a generalist only, a neurologist and a generalist (i.e., collaborative care), or by another specialist during the index hospitalization. METHODS: This study uses Cox regression to analyze claims and enrollment data from 44,099 Medicare beneficiaries 65 years of age and older and discharged with acute ischemic stroke from 1998 to 2000 in 11 US metropolitan regions. RESULTS: Patients seen by neurologists had more severe strokes than patients seen by generalists, though patients seen by generalists had more comorbidities. Patients seen by neurologists (alone or collaboratively) had a 10 and 16% lower risk of 30-day mortality, respectively. Patients seen by a neurologist only had a 12% lower risk of rehospitalization for infections and aspiration pneumonitis. In contrast, patients seen by neurologists had a higher risk of rehospitalization for atherosclerotic (cardiovascular and non-acute cerebrovascular) disease. Patients seen by neurologists were more likely to be discharged to inpatient rehabilitation, had longer lengths of stay, and were more likely to receive warfarin after discharge. CONCLUSIONS: Results support the hypothesis that neurologists improve outcomes specifically by reducing the potential for aspiration (through increased swallowing evaluations) or by improving functioning (through use of rehabilitation therapy). Future studies should continue to examine the mechanisms by which neurologists may achieve better outcomes in stroke care.

A systems approach to identifying inappropriate use of controlled substances: the need for balance.

BACKGROUND: The diversion, abuse, and inappropriate use of controlled substances remain of concern among health care practitioners, insurers, and policy makers in the United States. The principle of "balance" represents a need to establish a system of control to prevent abuse, trafficking, and diversion of controlled substances, while ensuring their medical availability for legitimate patients. ADMINISTRATIVE DATABASES TO STUDY OUTCOMES AND QUALITY OF CARE: Some models employ pattern recognition within administrative health databases, for example, to examine outcomes and quality of medical care and monitor fraudulent behaviors and inappropriate medical care. Patients' use of resources or variations in practitioners' practice patterns can be examined. A SYSTEMS APPROACH TO ADDRESS INAPPROPRIATE USE OF CONTROLLED SUBSTANCES: A systems approach would require collaboration with medical and pharmacy directors, systems analysts, coding experts, legal experts, and clinicians to develop the claims-based model. Once a patient and/or practitioner with possible diversion or abuse are identified, a second step is required to distinguish inappropriate and appropriate behaviors and medical care. CONCLUSION: Programs to detect misuse of controlled substances must be validated through clinical research, and a consensus should be reached as to what constitutes a breach of accepted medical practice.

Rehospitalization and survival for stroke patients in managed care and traditional Medicare plans.

BACKGROUND: Stroke affects more than 500,000 older persons each year in the United States, but no studies have compared older stroke patients in Medicare health maintenance organizations (HMOs) and fee-for-service (FFS) after recent changes in FFS reimbursement. OBJECTIVES: We sought to compare utilization and outcomes after stroke in Medicare HMO and FFS. DESIGN: We reviewed administrative data in 11 regions from Medicare and a large national health plan. SUBJECTS: We studied Medicare beneficiaries 65 years and older discharged with ischemic stroke during 1998-2000, ie, 4816 HMO patients and a random sample of 4187 FFS patients from 422 hospitals. MEASURES: We measured survival, rehospitalization, length of stay, discharge destination, and warfarin use. RESULTS: Overall, HMO patients were younger, male, non-Caucasian, and had fewer comorbid conditions. When compared with FFS patients, HMO patients were more likely to be rehospitalized within 30 days for a primary diagnosis of ischemic stroke (Adjusted Hazard Ratio = 1.45, 95% Confidence Interval [CI] 1.14-1.83) or ill-defined conditions (eg, rehabilitation services) (2.87, 95% CI 1.85-4.46) and less likely to be rehospitalized for fluid and electrolyte disorders (0.54, 95% CI 0.34-0.87) or circulatory/respiratory problems (0.77, 95% CI 0.60-0.98). There were no consistent differences in 30-day mortality or in 1-year rehospitalization or mortality for 30-day survivors. HMO patients also were much less likely to be discharged to rehabilitation facilities, slightly less likely to be discharged to skilled nursing facilities and to have a shorter length of stay, and did not differ in the use of home care services or warfarin use when compared with FFS patients. CONCLUSIONS: Traditional measures of quality such as 30-day rehospitalization may not be valid when comparing HMO and FFS patients if differences might reflect an alternative service mix. Utilization of post-acute care for FFS patients appears similar to HMO patients except for discharge to rehabilitation facilities.

Pneumonia in nursing home residents: factors associated with in-home care of EverCare enrollees.

OBJECTIVES: To identify determinants of whether nursing home (NH) residents enrolled in EverCare were admitted to in-home intensive service days (ISDs) rather than a hospital when they were thought to have pneumonia. DESIGN: Retrospective cross-sectional. SETTING: EverCare operations in five metropolitan areas. PARTICIPANTS: EverCare enrollees admitted to ISDs or a hospital for suspected pneumonia in 2002. MEASUREMENTS: Member, nurse practitioner, physician, and NH characteristics extracted from EverCare's administrative data and Online Survey Certification and Reporting NH data. RESULTS: Multivariable logistic regression indicated that admission to ISDs (65% of cases) was positively associated with age (odds ratio (OR)=1.04. 95% confidence interval (CI) 1.03-1.04), advance directives not to hospitalize (OR=2.88, 95% CI=1.76-4.72), or perform cardiopulmonary resuscitation, 3.09 (2.44-3.91), and hours worked by the NH's registered nurses (OR=4.34, 95% CI=1.74-10.8). Admission to ISD was less likely on weekends (OR=0.30, 95% CI=0.21-0.43), when residents had renal insufficiency (OR=0.61, 95% CI=0.49-0.76), and when the resident was covered by Medicaid (OR 0.87, 95% CI=0.82-0.93). CONCLUSION: Exploration of ways to extend services to weekends, increased availability of registered nurse staff, attention to advance directives, and a better understanding of the role of Medicaid might increase the likelihood of caring for EverCare enrollees with suspected pneumonia in their NH.

National health data warehouse: issues to consider.

A national data warehouse that links public and private data could be used to monitor trends in healthcare costs, utilization, quality of care, and adherence to quality guidelines and changes in treatment protocols. The development of the data warehouse, however, would require overcoming a number of political and technical challenges to gain access to private insurance data. This article outlines recommendations from a national conference sponsored by the Agency for Healthcare Research and Quality (AHRQ) on the private sector's role in quality monitoring and provides an operational outline for the development of a national private sector health data warehouse.

Forecasting changes in physician services per capita in Minnesota through 2030.

As the population ages and the ratio of retirees increases, the likely supply of physicians and physician services over the next few decades is being closely scrutinized. In this article, we use simple regression models to predict the supply of physicians and physician-hours per capita in Minnesota through the year 2030. We present the results from two models. The first uses data on all practicing physicians in the years 1995 to 2000 and projections for the entire population. The second "adjusted" model uses data on physicians who were younger than 65 in the years 1995 to 2000 and projections for the population 65 and older. The adjusted model represents a "worst case scenario" that removes physicians who typically work fewer hours from the count of physicians and retains the population needing the most health care services.

Identifying controlled substance patterns of utilization requiring evaluation using administrative claims data.

OBJECTIVES: To develop a systems approach to identify, for further evaluation, patients with potential controlled substance misuse or mismanagement using software queries applied to administrative health claims data. STUDY DESIGN: Retrospective validation of the system using insurance claims. PATIENTS AND METHODS: Data from administrative health claims databases representing nearly 7 million individuals younger than 65 years were used by multidisciplinary expert panels to develop and validate controlled substance patterns of utilization requiring evaluation (CS-PURE) criteria. RESULTS: Thirty-four CS-PURE queries were developed in SAS and applied to administrative claims records to identify patients with potential controlled substance misuse or mismanagement. From these, we identified 10 CS-PURE with the highest expert agreement that intervention was warranted. Expert panel agree, ment that CS-PURE correctly identified cases ranged from 48% to 100%, with at least 50% agreement in 9 of 10 CS-PURE. The prevalence rates for CS-PURE ranged from 0.001% to 0.252%. This translates to identifying between 5 and 1116 patients for individual CS-PURE in a 500 000-member health plan. CONCLUSIONS: We developed and empirically validated a group of queries using CS-PURE to identify patients with potential controlled substance misuse or mismanagement that would warrant further evaluation by the treating physician, a quality assurance function, or the medical director. Claims-based CS-PURE identification is generalizable to most health insurers with access to medical and pharmaceutical claims records. Although CS-PURE are not direct measures of misuse, they can direct attention to potential problems to determine if intervention is needed.

Alcohol dependence and the price of alcoholic beverages.

This study estimates the impact of the price of alcoholic beverages on latent dimensions of current alcohol dependence and abuse. A three-part econometric model is used to estimate the impact of price on three latent dimensions (factors). For heavier drinking, the estimated price elasticity is -1.325 (P = 0.027); for physical and other consequences of drinking, -1.895 (P = 0.003); for increased salience of drinking, -0.411 (P = 0.339). For a single latent factor characterized simply as dependence/abuse, estimated price elasticity is -1.487 (P = 0.012). These results suggest that higher prices for alcohol reduce important dimensions of current alcohol dependence and abuse.

The role of the private sector in monitoring health care quality and patient safety.

BACKGROUND: As payers, purchasers, and providers, both the public and private sectors have a stake in developing sound methods of measuring health care quality and patient safety. However, the role of the private sector in a national quality monitoring system remains largely underdeveloped. PRIVATE SECTOR ROLE IN HEALTH CARE QUALITY MONITORING: There have been some attempts to pool private-sector data through health care industry efforts to measure and monitor the quality of health care services. Yet despite a number of public/private partnerships, no standard method exists for measuring and monitoring health care quality and safety across public and private payers. THE AHRQ WORKSHOP ON PRIVATE-SECTOR QUALITY MONITORING: The Agency for Healthcare Research and Quality (AHRQ) sponsored a workshop in fall 2000 to address the private sector's role in monitoring quality in the health care system. National experts developed a conceptual framework and recommendations on the design and scope of a private-sector data monitoring system. Ten key attributes of the monitoring system, such as timeliness of reports, flexibility, efficiency, and linkability, were identified. Barriers and gaps to the development of such a system include the cost of data collection, the diversity of the units of data collection, data privacy, and limitations of administrative data elements. SUMMARY: A comprehensive, public/private data collection system would address the multidimensional nature of quality and use data to effectively represent this complexity to the extent possible.

Effect of tiered prescription copayments on the use of preferred brand medications.

BACKGROUND AND OBJECTIVE: Health plans are increasingly using more open drug formularies that offer differential prescription copayments as an incentive to enrollees to use brands that plans prefer. How much this financial incentive affects use of preferred brands has not been widely reported. The aim of this study was to estimate the effect of tiered copayments on the choice between preferred and nonpreferred brand medications. MATERIALS AND METHODS: Longitudinal logistic regression analyses of pharmacy claims from 1998 and 1999 comparing concurrent groups that were or were not exposed to tiered copayments. SUBJECTS: Enrollees in four independent physician practice association model health plans who had pharmacy claims for angiotensin converting enzyme inhibitors (ACEI), proton pump inhibitors (PPI), or hydroxymethylglutaryl coenzyme A reductase inhibitors (STATINS). OUTCOME MEASURE: Change in the percentage of prescription claims that were for preferred brands. MAIN RESULTS: Regression adjusted estimates of the average net increase in the percentage use of preferred brands of ACEI, PPI and STATIN from first quarter 1998 to third quarter 1999 attributed to tiered prescription copayments were 13.3 (P = 0.001), 8.9 (P = 0.03), and 6.0 (P <0.001) percentage points, respectively. CONCLUSIONS: Tiered prescription copayments were associated with a significant shift from nonpreferred to preferred brand medications. This type of financial incentive can help purchasers providing open access drug benefits by steering use of medications toward lower cost brands. The clinical effects of changes in medication use brought about differential copayments warrant further investigation.
