Lessons from experienced guideline implementers: attend to many factors and use multiple strategies.

BACKGROUND: Studies of clinical guideline implementation have focused almost entirely on changing individual clinician behavior with single intervention strategies and without much attention to the situational context. The goal of this project was to learn from clinic leaders, seasoned in the guideline implementation process, what contextual variables they viewed as important and whether implementation success could be expected if only a single implementation strategy was used. METHODS: In 1998, 12 people with extensive experience in leading clinical guideline implementation were identified who were thought to have particularly keen insight into the process. They were interviewed to generate variables they considered important, as well as strategies they considered effective when used appropriately. A modified nominal group/Delphi process was then used for rating these variables and strategies, and the reactions of international experts were obtained to add perspective to this information. RESULTS: Eighty-seven variables and 25 strategies were identified, clustering in 6 categories (ranked in order of importance by the panel): organizational capabilities for change, infrastructure for implementation, implementation strategies, medical group characteristics, guideline characteristics, and external environment. All six categories were considered to be important, key, or essential by the experienced implementers, although variables within a medical group that directly affect its ability to undertake planned change were rated as much more important than either guideline characteristics or the external environment. DISCUSSION: Although the opinions of those experienced in the process of guideline implementation are primarily of value for generating hypotheses, panel members believe that implementation efforts focusing on the individual physician with a single strategy are unlikely to be successful. Rather, implementation efforts must use multiple strategies that take account of multiple characteristics of the guideline, practice organization, and external environment.

Effect of glucose supplement timing on protein metabolism after resistance training.

We determined the effect of the timing of glucose supplementation on fractional muscle protein synthetic rate (FSR), urinary urea excretion, and whole body and myofibrillar protein degradation after resistance exercise. Eight healthy men performed unilateral knee extensor exercise (8 sets/approximately 10 repetitions/approximately 85% of 1 single maximal repetition). They received a carbohydrate (CHO) supplement (1 g/kg) or placebo (Pl) immediately (t = 0 h) and 1 h (t = +1 h) postexercise. FSR was determined for exercised (Ex) and control (Con) limbs by incremental L-[1-13C]leucine enrichment into the vastus lateralis over approximately 10 h postexercise. Insulin was greater (P < 0.01) at 0.5, 0.75, 1.25, 1.5, 1.75, and 2 h, and glucose was greater (P < 0.05) at 0.5 and 0.75 h for CHO compared with Pl condition. FSR was 36.1% greater in the CHO/Ex leg than in the CHO/Con leg (P = not significant) and 6.3% greater in the Pl/Ex leg than in the Pl/Con leg (P = not significant). 3-Methylhistidine excretion was lower in the CHO (110.43 +/- 3.62 mumol/g creatinine) than P1 condition (120.14 +/- 5.82, P < 0.05) as was urinary urea nitrogen (8.60 +/- 0.66 vs. 12.28 +/- 1.84 g/g creatinine, P < 0.05). This suggests that CHO supplementation (1 g/kg) immediately and 1 h after resistance exercise can decrease myofibrillar protein breakdown and urinary urea excretion, resulting in a more positive body protein balance.

National Asthma Education and Prevention Program working group report on the financing of asthma care.

The financing of asthma care is the third topic of the National Asthma Education and Prevention Program Task Force Report on the Cost Effectiveness, Quality of Care, and Financing of Asthma Care. This working group explored the effects of financing on access to services, treatment of asthma, and potential health outcomes. Over the course of a year, the working group collected and analyzed information pertaining to the various types of public and private health care financing mechanisms, including both insurance-based and non-insurance-based issues. The group examined the published literature and gathered information from four public hearings conducted across the nation. The result of this synthesis of information on health care financing and asthma care is a set of 12 recommendations that seek to improve the financing of asthma care.

Profiling resource use by primary-care practices: managed Medicare implications.

Variations in elderly Medicare beneficiaries' health service use are examined using a 100-percent sample of fee-for-service (FFS) claims data from Alabama, Iowa, and Maryland. Provider specialty, group practice type, practice size, and location are found to be significant factors affecting hospital and ambulatory care utilization and cost, after controlling for patient and regional characteristics. These results provide insights into utilization and cost expectations from different types of primary-care gatekeepers as the Medicare managed care market develops.

Variation in office-based quality. A claims-based profile of care provided to Medicare patients with diabetes.

OBJECTIVES: To demonstrate that claims data "profiling" can be used as an ongoing method to support ambulatory care quality improvement; to measure the quality of office-based care provided to elderly patients with diabetes in three states; and to identify factors associated with better attainment of quality standards. STUDY DESIGN: A cross-sectional study based on a 100% sample of the Medicare claims (Part B and Part A) submitted between July 1, 1990, and June 30, 1991. SETTING: All primary care practices (both solo and group) actively seeing Medicare patients with diabetes in Alabama, Iowa, and Maryland (n = 2980). PATIENTS: All elderly (> or = 65 years) Medicare patients seen by the study physicians and assigned a diagnosis of diabetes (n = 97,388) by any office-based physician during the year. MAIN OUTCOME MEASURES: The proportion of patients with diabetes receiving the following procedures (from any provider) at least once during the study period: hemoglobin A1C measurement, ophthalmologic examination, total cholesterol measurement, and blood glucose measurement. We considered the first three services to be optimally recommended and blood glucose measurement to be of limited use. RESULTS: Based on analyses of services provided in the ambulatory setting, we found that 84% of diabetics did not appear to receive the recommended hemoglobin A1C measurement, 54% did not see an ophthalmologist, and 45% received no cholesterol screening. Practice patterns varied considerably across the three states (up to 2.38-fold), even after adjusting for patient case mix and physician characteristics. Patients of general practitioners were less likely to meet recommended quality criteria than patients of internists or family practitioners. Patients receiving care from rural practitioners were less likely to receive services, either recommended or not, than those in urban locations. CONCLUSIONS: Elderly patients with diabetes do not appear to be receiving optimal care. This study underscores the value of practice guideline development and dissemination in the ambulatory arena. This study provides substantial evidence that existing administrative claims data can be used to support ambulatory quality improvement activities.

Designing and using measures of quality based on physician office records.

This article presents our principles for developing performance measures to assess the quality of ambulatory care. The measures were developed as part of a project for developing and evaluating methods to promote ambulatory care quality (DEMPAQ). We describe our design for the performance measures, present examples of the DEMPAQ review criteria, and show the formats we used to feed back information to physicians. We conclude by presenting the results of our appraisal of the performance measures showing how evaluation can aid in the interpretation of measurement findings.

Evaluation of a nurse-based hypertension management program: screening, management, and outcomes.

This article reports the experience of patients with elevated blood pressure scheduled to be seen in a nurse-based hypertension management program in a large multispecialty group practice. The hypertension management program is a screening and follow-up program designed to improve the measurement and management of patients' blood pressure with standardized protocols. The cohort for this study of the effectiveness of the hypertension management program consisted of 200 patients with elevated blood pressure (140 referred directly for management and counseling, 60 entered through screening). At entry, only 17% of the patients had blood pressure within controlled limits (< 140/90 mm Hg). One year after entry in the management phase of the program, systolic pressure had decreased an average of 6.20 mm Hg (P < 0.01), and 44% of patients had blood pressure within controlled limits (P < 0.001). These results suggest that the use of standardized screening techniques using multiple measurements helps to ensure that patients will not be unnecessarily treated. Furthermore, patients who entered the program successfully lowered their blood pressure and maintained the reduction over time.

Developing a quality improvement database using health insurance data: a guided tour with application to Medicare's National Claims History file.

Health policy researchers are increasingly turning to insurance claims to provide timely information on cost, utilization, and quality trends in health care markets. This research offers an in-depth description of how to systematically transform raw inpatient and ambulatory claims data into useful information for health care management and research using the Health Care Financing Administration's National Claims History file as an example. The topics covered include: (a) understanding the contents and architecture of claims data, (b) creating analytic files from raw claims, (c) technical innovations for health policy studies, (d) assessing data accuracy, (d) the costs of using claims data, and (e) ensuring confidentiality. In summary, claims data are found to have great potential for quality of care analysis. As in any analysis, careful development of a database is required for scientific research. The methods outlined in this study offer health data novices as well as experienced analysts a series of strategies to maximize the value of claims data for health policy analysis.

A computerized system for reviewing medical records from physicians' offices.

BACKGROUND: Review of clinical performance in office-based care is increasing in importance as more medical care shifts to outpatient settings. Decisions made in primary care settings can save lives and limit disability through prevention and early intervention in disease. Information is needed to assess quality of care by answering such questions as whether drugs are prescribed and monitored appropriately, follow-up on serious health threats is carried out promptly, or procedures are performed for appropriate indications. Moreover, data from medical records are essential to provide important clinical information not found in the more widely used administrative data sets. Managed care organizations, too, face the need to respond to requests for objective information about the quality of primary care that they provide. Those organizations now planning assessments of primary care will need to consider the cost of obtaining information from medical record review. METHODS: The DEMPAQ Record Review System (DRRS) is a tool for peer review organizations (PROs) to use to review ambulatory care given to Medicare beneficiaries in physicians' offices. The system is described in terms of functions (activities commonly performed in the course of an office visit, such as drug prescribing), indicators (summary measures of quality for each key function of clinical care), and clinical items (for example, specific drugs or tests for each function and indicator)--a total of 263 indicators in all. A framework is provided for measuring the operational costs of a review system based on medical records. RESULTS: The costs directly associated with a fully operational review system were less than $48 per case in Iowa and Alabama and $72 per case in Maryland. On average, reviewers spent about an hour per case signed on to DRRS; average review times declined over time with practice. About half the cost of the review process is accounted for by administrative costs. Therefore, once the effort has been made to obtain records, the additional cost of abstracting more data items is relatively low. Since samples of 300-500 records suffice to measure average performance for a region or state, costs per region/state approximate $15,000 to $25,000 per measurement cycle for assessment of a wide array of clinical areas. SUMMARY: The cost of collecting information on quality of care from medical records using the review system falls within current budgets for PRO review. However, organizations planning to implement a quality improvement campaign should also consider the costs of analyzing the data, reporting information to physicians, and continuing to monitor changes in performance.

Focus on quality: profiling physicians' practice patterns.

This article presents a physician practice profiling system developed using Medicare data to evaluate the quality of care provided by primary care physicians. We discuss four attributes to physicians' practice profiles that make them useful for quality improvement: flexibility, user involvement in developing profiles, explicit plans for evaluation, and fairness to groups of providers. This system serves as a model for physician profiling with a focus on quality of care measurement.

Beyond report cards: a health profile for HealthPartners Health Plan and the Business Health Care Action Group.

HealthPartners Health Plan and the "Business Health Care Action Group" (a buyer's coalition) operate in a market place increasingly concerned about accountability and quality improvement. Improving the population's health is a strategy that satisfies the mission and business purposes of employers and health care providers alike. Proposed quality measures and "report cards" have focused on clinical performance standards such as procedure rates or adherence to clinical practice guidelines. This paper describes a unique collaboration between an HMO and a purchasing coalition to assess member health status and health risks as a catalyst for increasing consumer involvement in health care.

Detection of beta-blocker use in people with asthma.

Although there have been numerous reports of adverse outcomes for people with asthma who are placed on beta-blockers, there has been no description of how often people with asthma receive prescriptions for beta-blockers. Despite the fact that pharmacy claims are available and can be used for clinical evaluation, there has been no description of a practical surveillance or warning system to recognize and reduce the rate of beta-blocker use in people with asthma. This study used administrative claims data to estimate the prevalence of patients with asthma who also had prescriptions for beta-blockers. Chart audit was used to supplement our understanding of the causes of the problem and its consequences. In the calendar year 1989, in a large midwestern group practice that contracts with a single health maintenance organization (HMO), 3,170 HMO patients presumed to have asthma were identified. Of those 3,170 patients, 44 or 1.4% also had filled prescriptions for beta-blockers. The occurrence of beta-blocker use varied by age group: from less than 1% in patients below 30 years of age, rising to 8.9% in patients aged 60 to 69. Two of the patients with asthma who had prescriptions for beta-blockers were hospitalized for asthma in the study period. In 61% of the cases, different physicians managed the asthma care from those who prescribed the beta-blockers. In the remaining 39%, one physician was responsible for both the asthma care and beta-blocker prescription. We conclude prescribing beta-blockers for individuals with asthma is not uncommon. Current systems of administrative claims data permit the development of warning systems to help avert adverse outcomes.

[Compartment syndrome of the legs and scurvy].

Old people living alone and in poverty are most at risk for developing scurvy, but the diagnosis may be missed unless the physician is aware of it. A 42-year-old immigrant living in poverty was treated surgically at the Hôtel-Dieu Hospital in Montreal for a compartment syndrome of the leg. She had ecchymoses on the skin of the leg and an interstitial hematoma in both posterior compartments. Three weeks later, she was readmitted with more swelling in the leg, gingivitis, hemorrhagic folliculitis, petechiae and gastrointestinal hemorrhage. Her response to vitamin C was remarkable and confirmed the diagnosis of scurvy.

Association of volume with outcome of coronary artery bypass graft surgery. Scheduled vs nonscheduled operations.

Empirical evidence suggests that mortality rates for coronary artery bypass graft (CABG) surgery are lower in hospitals that perform a higher volume of the procedure. In recent years, the criteria for CABG surgery have been expanded to include patients with a wide variety of co-morbidities. To address the question of whether the volume-outcome relationship continues to exist for this new group of patients, discharge abstracts for 18,986 CABG operations at 77 hospitals in California in 1983 were analyzed using multiple-regression techniques. Higher-volume hospitals had lower in-hospital mortality (adjusted for case mix); this effect was greatest in patients who might be characterized as having "non-scheduled" CABG surgery. Higher-volume hospitals also had shorter average postoperative lengths of stay and fewer patients with extremely long stays. The results of this study suggest that the greatest improvement in average outcomes for CABG surgery would result from the closure of low-volume surgery units.
