How can physicians keep up-to-date?
Keeping one's personal fund of knowledge current is one of the most formidable challenges that physicians face. This article considers a few strategies that may help physicians as they struggle to keep their knowledge up-to-date. Physicians need to develop their own goals for staying current, systematically and periodically search the literature for high-quality material relevant to the topics on their agendas, become facile with critical appraisal of the literature, and schedule time for reading. One of the responsibilities of any professional is to maintain expertise, and this responsibility is probably nowhere more critical, or more difficult, than in the profession of medicine.

Relationship between ambulatory care accessibility and hospitalization for persons with advanced HIV disease.
Specific features of ambulatory care, such as accessibility, may influence hospital use for patients with HIV infection. To identify clinic features associated with a lower risk of hospitalization, 6,280 New York state Medicaid enrollees diagnosed with AIDS in 1987-1992 and managed by one of 157 surveyed clinics were studied. The odds of hospitalization in the year before AIDS diagnosis were associated with five clinic features that facilitate the accessibility of care: (1) evening/weekend hours, (2) case manager, (3) appointments within 48 hours, (4) telephone consultation, and (5) whether the clinic handled urgent care. Hospitalization in the year before AIDS diagnosis occurred for 49 percent of patients. Three of the five accessibility features had unadjusted associations with lower hospitalization rates. The adjusted odds of hospitalization were lower for patients in clinics with extended hours (OR = 0.77, 95% CI = 0.63, 0.93) and for patients in clinics with four or more accessibility features compared with those in clinics with less than two features (OR = 0.67; 95% CI = 0.50, 0.89).

Impact of a DRG-based hospital financing system on quality and outcomes of care in Italy.
OBJECTIVE: To examine potential changes in quality of care associated with a recent financing system implementation in Italy: in 1995, hospital financing reform implemented in Italy included the introduction of a DRG-based hospital financing system with the goals of controlling the growth of hospital costs and making hospitals more accountable for their productivity. DATA SOURCES: Hospital discharge abstract data from 1993 through 1996 for all hospitals (N=32) in the Friuli-Venezia-Giulia region of Italy. Regional population data were used to calculate rates. STUDY DESIGN: Changes between 1993 and 1996 in hospital admissions, length of stay, mortality rates, severity of illness, and readmission rates were studied for nine common medical and surgical conditions: appendicitis, diabetes mellitus, colorectal cancer, cholecystitis, bronchitis/chronic obstructive pulmonary disease (COPD), bacterial pneumonia, coronary artery disease, cerebrovascular disease, and hip fracture. PRINCIPAL FINDINGS: The total number of ordinary hospital admissions decreased from 244,581 to 204,054 between 1993 and 1996, a population-based decrease of 17.3 percent (p<.001). The mean length of stay decreased from 9.1 days to 8.8 days, resulting in a 21.1 percent decrease in hospital bed days (p<.001). Day hospital use increased sevenfold from 16,871 encounters in 1993 to 108,517 encounters in 1996. The largest decrease in hospital admissions among study conditions was a 41 percent decrease for diabetes (from 2.25 per 1,000 in 1993 to 1.31 in 1996, p<.001). For eight of the nine conditions, severity of illness increased. Differences between severity-adjusted expected and observed in-hospital mortality rates were small. CONCLUSIONS: Observed trends showed a decrease in ordinary hospital admissions, an increase in day hospital admissions, and a greater severity of illness among hospitalized patients. There was little or no change in mortality and readmission rates. Administrative data can be used to track changes in patterns of care and to identify potential quality problems deserving further review.

The relationship of clinic experience with advanced HIV and survival of women with AIDS.
OBJECTIVE: Hospital and physician experience have been linked to improved outcomes for persons with HIV. Because many HIV-infected patients receive care in clinics, we studied clinic HIV experience and survival for women with AIDS. DESIGN: Retrospective cohort study of women with AIDS whose dominant sources of care were clinics. Clinic HIV experience was estimated as the cumulative number of Medicaid enrollees with advanced HIV who used a particular clinic as their dominant provider up to the year of the patient's AIDS diagnosis: low experience (< 20 patients), medium (20-99 patients), high (> or = 100 patients). Proportional hazards models examined relationships between experience and survival. SETTING: A total of 117 New York State clinics. PATIENTS: A total of 887 New York State Medicaid-enrolled women diagnosed with AIDS in 1989-1992. MAIN OUTCOME MEASURE: Survival after AIDS diagnosis. RESULTS: In later study years (1991-1992), patients in high experience clinics had an approximately 50% reduction in the relative hazard of death (0.53; 95% confidence interval, 0.35-0.82) compared with patients in low experience clinics. Adjusting for demographic and clinical variables, 71% of patients in high experience clinics were alive 21 months after diagnosis compared with 53% in low experience clinics. Experience and survival were not significantly associated in the early study years (1989-1990). CONCLUSIONS: In more recent years, women with AIDS receiving care in high experience clinics survived longer after AIDS diagnosis than those in low experience clinics, providing further evidence of a relationship between provider HIV experience and outcomes.

Clinic characteristics associated with reduced hospitalization of drug users with AIDS.
OBJECTIVE: To identify features of ambulatory care associated with reduced hospitalization among drug users with acquired immunodeficiency syndrome (AIDS). METHODS: A nonconcurrent prospective study of hospital use by 1,369 drug users with AIDS was conducted using data from New York State Medicaid research data files linked to telephone interview data from directors of ambulatory care clinics serving this group. RESULTS: Follow-up averaged 29 months, during which 88% of subjects were hospitalized at least once. On average, those hospitalized spent 14% of follow-up time as inpatients. Hospitalization was less likely for patients in clinics with case managers (adjusted odds ratio = 0.42, 95% confidence interval 0.25, 0.69) or high director's rating of coordination of care (adjusted odds ratio = 0.50, 95% confidence interval 0.29, 0.89). Multivariate analysis showed significantly less time in hospital for patients in clinics with methadone maintenance, case managers, high continuity ratings, and clinic physicians attending for hospitalized clinic patients. CONCLUSIONS: Drug users with AIDS rely heavily on inpatient care, but those followed in clinics featuring greater coordination and offering special services, including methadone treatment and case management, appear to have significantly less hospital use.

Combined cardiac catheterization for uncomplicated ischemic heart disease in a Medicare population.
PURPOSE: Experts recommend left heart catheterization alone to evaluate uncomplicated ischemic heart disease, reserving right heart catheterization for specific indications. Yet some centers routinely perform combined cardiac catheterization (left heart catheterization and right heart catheterization together). SUBJECTS AND METHODS: Using 1992-1993 Pennsylvania Medicare claims for cardiac catheterizations (n = 41,180), we examined rates of combined cardiac catheterization for patients with uncomplicated ischemic heart disease for each hospital (n = 73) that performed catheterizations. We compared combined cardiac catheterization rates among hospitals and developed a multivariable model to identify hospital characteristics associated with high combined cardiac catheterization rates. A random sample of cases from the 10 hospitals with the highest combined cardiac catheterization rates were reviewed to determine justification, complications, and results of combined cardiac catheterization. RESULTS: Of the 41,180 cardiac catheterizations, 14,177 (34%) were combined procedures. Among hospitals, combined cardiac catheterization rates varied from 2% to 98%. Hospital characteristics associated with high combined cardiac catheterization rates included having a cardiology fellowship program (relative risk [RR] 1.7, 95% confidence interval [CI] 1.1-2.7), location in eastern Pennsylvania (RR 2.5, 95% CI: 1.8-3.5), and volume of catheterizations performed (RR 0.95, 95% CI: 0.91-0.99/100 procedures). For reviewed cases, the most common justification for combined cardiac catheterization was planned revascularization (44%), which is not a specific indication. Only 49% of cases had at least one specific indication for right heart catheterization (range by hospital, 30%-74%). The abnormal findings on the right heart catheterization rarely appeared to change management. CONCLUSION: There is wide variation in the practice of combined cardiac catheterization, which appears to be related to teaching status and geographic location. The most common justification for the procedure was planned revascularization, which is not one of the specific indications supported by current literature.

The relationship between the race/ethnicity of generalist physicians and their care for underserved populations.
OBJECTIVES: The purpose of this study was to examine empirically the relationship between physicians' race or ethnicity and their care for medically underserved populations. METHODS: Generalist physicians who received the MD degree in 1983 or 1984 (n = 1581) were surveyed. The personal and background characteristics of four racial/ethnic groups of physicians were compared with the characteristics of their patients. RESULTS: When the potentially confounding variables of gender, childhood family income, childhood residence, and National Health Services Corps financial aid obligations were controlled, generalist physicians from underrepresented minorities were more likely than their nonminority counterparts to care for medically underserved populations. CONCLUSIONS: Physicians from underrepresented minorities are more likely than others to care for medically underserved populations.

Important elements of outpatient care: a comparison of patients' and physicians' opinions.
OBJECTIVE: To compare patients' and physicians' opinions on the importance of discrete elements of health care as determinants of the quality of outpatient care. DESIGN: Analysis of results of a mailed survey. SETTING: Community-based internal medicine practices. PARTICIPANTS: 74 general internists and 814 patients randomly selected from the practices of these internists. MEASURES: 125 elements of care that covered nine domains were identified: physician clinical skill, physician interpersonal skill, support staff, office environment, provision of information, patient involvement, nonfinancial access, finances, and coordination of care. Participants rated each element on its importance to high-quality care on a 4-point scale: 1 = not important; 2 = of medium importance; 3 = of high importance; and 4 = essential. Patients' and physicians' ratings were compared for individual elements of care and for elements aggregated into domains. RESULTS: Survey response rates were 93% for physicians and 60% for patients. In an element-by-element comparison of ratings, ratings by the two groups differed substantially for 58% of the attributes. The most striking difference was seen in the domain of provision of information (median ratings, 3.56 for patients and 2.85 for physicians; P < 0.001). Ratings by the two groups also differed in the domains of clinical skill (3.75 for patients and 3.35 for physicians; P < 0.001), nonfinancial access (3.00 for patients and 2.87 for physicians; P < 0.001), and finances (3.00 for patients and 2.80 for physicians; P = 0.006). When relative rankings of the domains were compared, both groups agreed that clinical skill is most important; however, patients ranked provision of information second in importance whereas physicians ranked it sixth. CONCLUSIONS: Patients and physicians agreed that the most crucial element of outpatient care is clinical skill, but they disagreed about the relative importance of other aspects of care, particularly effective communication of health-related information. These differences in perception may influence the quality of interactions between physicians and patients.

Patient-centered medicine. A professional evolution.
American medicine is in the midst of a professional evolution driven by a refocusing of medicine's regard for the patient's viewpoint. Historically, medicine has been largely physician centered, but physicians have begun to incorporate patients' perspectives in ways that increasingly matter. Some call this shift "patient-centered" care. In support of the view that this refocusing reflects a broad professional shift, we describe the evolution to patient-centered care in many areas of medicine: patient care, health-related law, medical education, research, and quality assessment.

Preventing complications in diabetes mellitus: the role of the primary care physician.
Many Americans, knowingly or unknowingly, are afflicted with diabetes. Because of a lack of awareness or a disbelief that aggressive treatment benefits patients on the part of both patients and physicians, diabetes, particularly NIDDM, remains underdiagnosed and undertreated despite complications that can dramatically diminish quality of life. Increasing evidence that good glycemic control forestalls if not prevents these outcomes makes it the primary care physician's imperative to diagnose diabetes before complications develop. Physicians, through targeted screening and aggressive treatment of patients in whom they diagnose this chronic disease, can markedly reduce diabetes-related morbidity and mortality.

Patients' perceptions of office medical practice: judging quality through the patients' eyes.
With increasing pressure to measure quality, patient-based assessments of medical care are becoming increasingly important. Patients offer a unique perspective for evaluating the nontechnical aspects of medical care. This study reviews the importance of utilizing patients' perceptions to measure quality of care in office settings. It also reviews the principles required to conduct a well done survey. The concept of patient perceptions differs from the more commonly measured concept of patient satisfaction, in that perceptions measure whether a patients' needs and expectations are met, in addition to satisfaction. One of the most accurate and efficient means of measuring patients' perceptions is through the use of surveys. As with all standardized data collection, creating and performing high quality surveys of patients' perceptions can be challenging. Valid and reliable patient survey data can enable practitioners to identify areas for improvement, and demonstrate to external reviewers the quality of care they provide to their patients.

The impact of a regulation restricting medical house staff working hours on the quality of patient care.
OBJECTIVE: To examine the impact on patient care of a New York State regulation that restricted house staff working hours. DESIGN: Retrospective cohort study. SETTING: General medical service of an urban teaching hospital. PATIENTS: A total of 263 (94%) of 281 patients discharged from the study service during October 1988 and 263 (93%) of 283 patients discharged from the same service during October 1989. INTERVENTIONS: On July 1, 1989, New York State enacted a new regulation, Code 405, which limited residents' working hours and specified levels of supervision and ancillary support. MAIN OUTCOME MEASURES: In-hospital mortality, transfers to intensive care units, cardiopulmonary resuscitation attempts, discharge disposition, length of stay, medical complications, and house staff delays in ordering tests and procedures. RESULTS: Although the cohorts were comparable in severity of illness measures, more patients in 1989 suffered at least one medical complication (91 [35%] vs 59 [22%]; P = .002) and experienced at least one diagnostic test delay because of house staff (44 [17%] vs 4 [2%]; P < .001). These significant differences persisted after controlling for potential confounders in multivariate analyses. However, we found no significant differences in more serious outcomes: in-hospital mortality, transfer to intensive care unit, discharge disposition, or length of stay. CONCLUSION: These results suggest that restricted house staff working hours were associated with delayed test ordering by house staff and increased in-hospital complications. While these potentially deleterious effects on the quality of care did not result in statistically significant differences in more serious outcomes, further study at other hospitals is warranted to determine staffing strategies that optimize quality of care for patients, as well as medical education and quality of life for house officers.

The AHCPR guidelines on heart failure: comparison of a family medicine and an internal medicine practice with the guidelines and an educational intervention to modify behavior.
OBJECTIVES: The objectives of this study were to apply the Agency for Health Care Policy and Research (AHCPR) guideline for heart failure to the measurement of quality of care in the ambulatory setting, to compare the results for two large practices and to design an educational intervention for the two practices being studied. METHODS: A retrospective chart review was conducted on a random sample of 50 patients with heart failure selected from each of two outpatient practices: the general internal medicine practice and the family medicine practice at a large academic medical center. Five medical review criteria were developed from the AHCPR guideline for heart failure to compare the two practices with each other and the guidelines. An educational intervention was developed to modify physician behavior in regard to compliance with guidelines. RESULTS: Assessment of left ventricular function occurred in 79% of all cases. Of eligible patients, 68% were treated with angiotensin-converting enzyme inhibitors (ACE-Is). Of those patients treated with enalapril and captopril, 30% and 12%, respectively, were receiving the target dose as defined in the AHCPR guidelines. Of patients not eligible for treatment with ACE-Is, none were treated with hydralazine and nitrates. When the ejection fraction was less than or equal to 40%, 81% of eligible patients were treated with ACE-Is, whereas 59% were treated with ACE-Is when the ejection fraction was greater than 40%. Calcium channel blockers were used in the treatment of 42% of patients. A statistical difference (P = .05) was found between the two practices for documentation of left ventricular function, the use of ACE-Is for patients with ejection fraction less than or equal to 40%, and the use of calcium channel blockers and beta blockers. CONCLUSIONS: In the practices studied, there is underutilization of the documentation of left ventricular function, ACE-Is in eligible patients, target doses of ACE-Is, and the use of hydralazine and nitrates for ineligible patients. A higher proportion of patients receive ACE-I therapy when the ejection fraction is less than or equal to 40%. There may be inappropriate use of calcium channel blockers in some patients. There is unexplained clinical variation between the two practices studied.
