Maine Carpal Tunnel Study: small area variations.

As is the case for all elective procedures, small area variations occur in rates of surgery for carpal tunnel syndrome. A 1993 analysis of Maine data demonstrates that carpal tunnel release rates across population-based service areas varied 3.5-fold, from 0.82 to 2.87 per thousand. Four areas had rates significantly higher and 2 were significantly lower than the state average of 1.44 per thousand. Among many potential factors influencing variations, physician practice patterns appear to be the major contributor.

Mandatory practice self-appraisal: moving towards outcomes based continuing education.

Most organized physician continuing educational activities are undertaken without assessing their effects on long-term changes in physician practice patterns, patient outcomes or return on investment. Practice audit and practice self-appraisal are two activities that can be used to achieve these objectives. It is recommended that these be promoted from an educational perspective. A series of principles, including the mandatory application of practice audit and practice self-appraisal are proposed to guide the process. The identification of issues relating to learning, diffusion of information and behavioural change required to facilitate this change are briefly discussed.

Venous access: women are equal.

BACKGROUND: Arteriovenous fistulae (AVFs) are the preferred method of vascular access for hemodialysis patients; however, the current rate of AVF placement is only 25% to 30% in the United States. This prevalence is even smaller among women and attributed to their perceived inadequate vasculature. This commonly held view that women have less adequate vasculature for AVF placement than men has not been shown objectively in the literature. METHODS: To determine a difference in vasculature between the sexes, we retrospectively analyzed data on preoperative vascular mapping in 192 patients. During a 2-year period, vascular mapping of the upper extremities was routinely performed using duplex ultrasound in all patients requiring vascular access in our institution. RESULTS: One hundred six of these 192 patients were women, and 86 were men. There was no significant difference in vein size between men and women at any of the sites measured. A total of 87 fistulae were placed in 140 patients, 49% in women and 51% in men (P = 0.16). Prevalences of AVFs were 57% and 68% (P = 0.2) in women and men, respectively. Percentages of fistulae used at the initiation of hemodialysis therapy were 72% in women and 77% in men (P = 0.57). CONCLUSION: These data support the view that women have adequate vasculature for the placement of AVFs compared with men. We cannot explain the different outcomes found in other studies; however, we suggest that the differences are caused by physician practice patterns, not anatomic differences between men and women.

Drug treatment of stable angina pectoris and mass dissemination of therapeutic guidelines: a randomized controlled trial.

BACKGROUND: Public agencies responsible for implementing health care policies often adapt and disseminate clinical practice guidelines, but the effectiveness of mass dissemination of guidelines is unknown. AIM: To study the effects of guideline dissemination on physicians' prescribing practices for the treatment of stable angina pectoris. DESIGN: Randomized controlled trial. METHODS: A sample of 3293 Quebec physicians were randomly assigned to receive a one-page summary of clinical practice guidelines on the treatment of stable angina (in February 1999), to receive the summary and a reminder (in February and March 1999, respectively), or to receive no intervention (controls). The prescribing profiles of participants, as well as sociodemographic characteristics of the physicians and their patients, were examined for June-December 1999. RESULTS: The intervention had no effect on prescription rates of beta-blockers, antiplatelet agents, or hypolipaemic drugs. Compared to 1997 data for the same physicians, there was an overall 10% increase in appropriate prescription rates, irrespective of the intervention. DISCUSSION: In-house production and dissemination of clinical practice guidelines may not improve physicians' practice patterns if there is pre-existing substantial scientific consensus on the issue.

On defining small areas.

This study explores the relationship between small area and economic approaches to defining hospital markets. Both approaches attempt to link populations receiving care with providers who deliver it. The approaches differ fundamentally, however, in their view of the role of alternative sources of inpatient services. The small area approach attempts to minimize the number of hospitals in a market. Economic approaches attempt to include substitute sources of care. The economic literature also suggests that the availability of substitutes influences the use of health services. This literature is briefly reviewed, and the implications for the analysis of physician practice patterns are discussed. The study concludes that economic approaches to market definition are likely to be more fruitful in explaining variations in the use of services.

Overutilization of acute-care beds in Veterans Affairs hospitals.

The authors tested the hypothesis that the Department of Veterans Affairs (VA) hospitals would have substantial overutilization of acute care beds and services because of policies that emphasize inpatient care over ambulatory care. Reviewers from 24 randomly selected VA hospitals applied the InterQual ISD* (Intensity, Severity, Discharge) criteria for appropriateness concurrently to a random sample of 2,432 admissions to acute medical, surgical, and psychiatry services. Reliability of hospital reviewers in applying the ISD* criteria was tested by comparing their reviews with those of a small group of expert reviewers. Validity of the ISD* criteria was tested by comparing the assessments of master reviewers with the implicit judgments of panels of nine physicians. The physician panels validated the ISD* admission criteria for medicine and surgery (74% agreement with master reviewers, kappa > 0.4), whereas the psychiatry criteria were not validated (66% agreement, kappa 0.29). Hospital reviewers reliably used all three criteria sets (> 83% agreement with master reviewers, kappa > 0.6). Rates of nonacute admissions to acute medical and surgical services were > 38% as determined by the hospital and master reviewers and by the physician panels. Nonacute rates of continued stay were > 32% for both medicine and surgery services. Similar rates of nonacute admissions and continued stay were found for all 24 hospitals. Reasons for nonacute admissions and continued stay included lack of an ambulatory care alternative, conservative physician practices, delays in discharge planning, and social factors such as homelessness and long travel distances to the hospital. Using criteria that the authors showed to be reliable and valid, substantial overutilization of acute medicine and surgical beds was found in a representative sample of VA hospitals. Correcting this situation will require changes in physician practice patterns, development of ambulatory care alternatives to inpatient care, and modification of current VA policies determining eligibility for care.

Comparing the use of diagnostic tests in Canadian and US hospitals.

Although Americans pay much more for a day in the hospital than Canadians, we know little about whether inpatient physician practice patterns might explain some of this difference. The authors compared the utilization of all diagnostic imaging (plain radiographs, computed tomography (CT) and magnetic resonance imaging (MRI) scanning, ultrasound, nuclear medicine and vascular studies) and selected laboratory tests (hematology, basic biochemistry, and advanced biochemistry) for all patients discharged with selected medical and surgical diagnoses in 1990 and 1991 from four university hospitals and four community hospitals in Canada (n = 6,491) and the United States (n = 7,980). Overall, US medical patients received 22% more diagnostic tests than their Canadian counterparts (544.2 relative value units [RVUs] vs. 446.5 RVUs in Canada, P < 0.001), which was mainly the result of higher radiology use. Although mean radiology use was 40% higher in the United States (370.0 vs. 264.5 RVUs in Canada, P < 0.05), there was little difference in the use of laboratory tests between countries (174.2 vs. 182.4 RVUs in Canada, P = 0.3). Within radiology, only CT and MRI use differed significantly between countries (US patients received 119% more tests than Canadians). These findings were consistent after adjustments for age, gender, diagnosis-related group, and university status. Differences in test use between countries were mainly the result of more testing among the US elderly than counterparts in Canada. Among surgical patients, there was little difference between countries for radiology (76.3 vs. 67.3 RVUs in Canada, P < 0.05) and laboratory (83.6 vs. 91.4 RVUs in Canada, P < 0.05). Comparable inpatients admitted to US hospitals received more diagnostic tests than their Canadian counterparts even in hospitals with similar availability of technology. Differences between countries were larger for high-cost tests than for lower-cost tests. Much of the difference in test use is explained by more intensive use for the elderly in the United States.

Regional variation in angiography, coronary artery bypass surgery, and percutaneous transluminal coronary angioplasty in Manitoba, 1987 to 1992: the funnel effect.

OBJECTIVES: Administrative data from Manitoba, Canada document variation in procedure utilization rates over a period of 15 years. With coronary angiography and cardiovascular surgery centralized in the capital, Winnipeg, previous analyses from 1977 to 1983 found angiography and coronary artery bypass surgery (CABS) rates to be higher for residents of Winnipeg. Residents of the Western region had consistently lower rates; this variation in regional access appeared due to physician practice patterns. In this study all angiography patients were followed from 1987 to 1992 and rates of CABS and percutaneous transluminal coronary angioplasty (PTCA) calculated. METHODS: Cox proportional hazard multivariate regression models with five sociodemographic variables and two clinical variables (time from angiography to revascularization, and comorbidities) also were examined. RESULTS: Consistent regional variation was documented; rates in the Western region remain consistently low. A "funnel effect" is found; the fewer patients from a region referred for angiography, the fewer patients from that region who have CABS or PTCA. CONCLUSIONS: Implications of the persistence of these findings are discussed. Individuals in Western Manitoba probably have some of the lowest rates of coronary artery bypass surgery and percutaneous transluminal coronary angioplasty in North America.

The theory and methodology of provider profiling.

Physician profiling is the comparison of physician practice patterns to determine the existence and effects of significant differences in outcomes. To optimize care quality, these comparisons can be used to influence provider behavior through awareness when outcomes are poor or do not warrant provider expenditures. To maximize the value of such a technique, the underlying bases for comparison and the uses of derived data must be understood. Several factors must be considered or controlled for when determining comparable providers. Additionally, the worth or significance of findings must also be understood. This paper seeks to provide information in these two areas for the benefit of those responsible for managing care at all levels.

Health care rationing affecting older persons: rejected in principle but implemented in fact.

Health care resources are finite and, therefore, need to be rationed among potential users. Over the past decade and a half in the United States, a variety of explicit, official rationing schemes have been proposed, including some in which chronological age would play a significant role. For ethical and political reasons, it is very unlikely that any age-based rationing schemes will be adopted explicitly and officially. However, various de facto forms of health care rationing are occurring at present. This article outlines the implications of payer behavior, physician practice patterns, the development of evidence-based clinical practice parameters or guidelines, and reliance on consumer choice of health plans as unofficial and generally unacknowledged mechanisms of health care rationing that may exert an important impact on the accessibility of health services for older persons.

Variation in use of medical care services: higher risk or higher consumption?

The issue of variation in use of medical care is important in Florida and in other regions of the country. It is difficult to disaggregate the effects of differences in health risk of Medicare beneficiaries from physicians' practice patterns and patients' preferences for care. New risk-adjustment methods used by the Centers for Medicare and Medicaid Services may provide some insights, but they also raise similar questions about the influence of practice patterns on variation.

The small group consensus process for changing physician practices: influenza vaccination.

OBJECTIVE: To evaluate the effectiveness of a small group consensus process in enhancing compliance with guidelines for influenza vaccination among older HMO members. DESIGN: A controlled study of the practice of primary care physicians, with pre/post comparisons and a 2-year follow-up. SETTING: An 84,000 member prepaid staff model HMO group practice. PARTICIPANTS: Primary care clinicians (N = 36) practicing in a staff model HMO. INTERVENTION: A small-group process, including opinion leader, feedback, and group decision making. MAIN OUTCOME MEASURE: Percentage of patients in a given physician-panel who received influenza immunization. RESULTS: Improvement in vaccination rate from 60.8% to 72.35% (with further increases over 2 successive years), in the intervention group as compared with improvement in the control from 60.7% to 65.93%. CONCLUSION: In this model, the small group consensus process resulted in an alteration in physician practice pattern, yielding a significant improvement in immunization rates above the already-established level of 60%.

Using profiling for cost and quality management in the emergency department.

Overutilization and underutilization of resources are inappropriate and may result in unacceptable quality of care and increased morbidity. Current data are needed to monitor the use of clinical resources and help identify physicians with appropriate cost/quality outcomes and those who may have utilization or quality problems. Profiling is an analytical tool that uses epidemiological method to compare cost, service use, and quality of various physician practice patterns for a large number of patient encounters. To develop a profiling program, standards of care must be established and information systems must be instituted to measure resource utilization and care efficiency. Such a program can be especially valuable in the emergency department of hospitals, where wide variation in practice patterns may occur because of the episodic nature of patient encounters. A reduction in practice variations saves time and increase patient throughput in many cases.

Grouping patients by episode helps managers compare 'apples to apples' performance.

Apples to apples: When health care organizations group care by illness episode and include inpatient, outpatient, and pharmaceutical claims data, they can more appropriately compare physician practice patterns, identify targets for disease management efforts, and pinpoint particular aberrations in their data. Here's how Episode Treatment Groups (ETGs) make analysis easier for organizations, such as Oxford Health Plans--plus some sample ETG-driven reports.

Improving performance in diabetes care: a multicomponent intervention.

CONTEXT: Compliance with recommendations from the American Diabetes Association for management of patients with diabetes is not optimal. Changing physician practice patterns with provider-focused interventions can be difficult. We report results after implementation of a type 2 diabetes mellitus guideline. OBJECTIVE: To increase the annual rate of microalbumin/urine protein testing, dilated eye examinations, and foot examinations for patients with diabetes and to reduce overall levels of hemoglobin A1c (Hb A1c). DESIGN: Before-after study. INTERVENTION: From April 1996 to June 1998, a guideline on type 2 diabetes mellitus was implemented with multicomponent interventions. These included small group educational sessions led by opinion leaders, an electronic version of the guideline, audit with feedback, and enhanced clinical orders support. Medical records of random samples of patients with diabetes were audited for specific diabetes performance measures on a monthly basis. Baseline data were compared with results at the end of the implementation effort. SETTING: Southeastern Minnesota, excluding Olmsted County. PARTICIPANTS: Adult patients seen at one practice of 18 general internists. OUTCOME MEASURES: Outcome measures included Hb A1c values and annual performance of a urine protein test, foot examination, and dilated eye examination. RESULTS: Gradual, sustained; and statistically significant improvements in the three annual performance measures were observed. Urine protein testing increased from 24% to 66% (P = 0.001), dilated eye examinations increased from 63% to 84% (P = 0.001), and foot examinations increased from 86% to 97% (P = 0.001). Mean Hb A1c values +/- SD also improved from 7.8% +/- 1.0% to 7.1% +/- 0.7% (P < 0.001) in patients who received continuing care for diabetes. CONCLUSIONS: Statistically significant improvements were observed after continuous improvement efforts were focused on providers in an individual group practice. When used to implement a diabetes guideline, such interventions may improve delivery of services and reduce Hb A1c levels in patients with diabetes.

The geography of Medicare: explaining differences in payment and costs.

This issue brief examines the sources of variation in Medicare payment and costs across different geographic areas and different sites of care. It discusses payment policies that address variation in the cost of providing care, such as input price adjustments and special payments to hospitals. It also considers differences due to beneficiaries' health status and physicians' practice patterns. Finally, it explores policy options to address Medicare geographic variation.

What physicians should know about small area variation analysis.

Geographic variations in the use of medical care may occur because of differences in patient severity of illness, patient access or use of medical care, physician practice patterns, availability of technology, economic incentives, and malpractice concerns. These variations are leading to greater scrutiny of appropriateness and cost effectiveness of medical care.
