摘要:

Physician satisfaction with the laboratory testing process is one indicator of the physician's perception of the quality of laboratory testing and the effectiveness of the communication of the laboratory results. This study compares the level of satisfaction of physicians reporting their experience with human immunodeficiency virus type 1 (HIV-1) testing with the satisfaction levels of those physicians reporting their experience with hepatitis B virus (HBV) testing. By mail, 6,570 licensed San Diego County physicians were surveyed. Among those who tested for HIV-1 or HBV, their satisfaction with four different HIV-1 or HBV testing parameters was assessed: 1) specimen submission process, 2) test accuracy, 3) clarity of test report, and 4) turn-around time.Overall, physician satisfaction with both HIV-1 and HBV testing was high, particularly for test accuracy (means of 2.79 and 2.84, respectively on a 3-point scale), although slightly lower for turnaround time (means of 2.40 and 2.43, respectively). Mean satisfaction with the specimen submission process and test accuracy were higher for physicians who ordered HBV tests than for those who ordered HIV-1 tests. Satisfaction with the four HIV-1 testing process parameters varied significantly by physician specialty, practice type, and type of laboratory used. For HBV testing, significant differences were observed only for turnaround time. For both HIV-1 and HBV testing, those who received a final interpretation of laboratory results were more satisfied with test report clarity than those who did not.Although physician satisfaction with HIV-1 and HBV testing is high, this study identifies the least satisfied groups and specific areas in the testing process that may need improvement.

摘要:

Payers and policymakers are increasingly examining hospital mortality rates as indicators of hospital quality. To be meaningful, these death rates must be adjusted for patient severity. This research examined whether judgments about an individual hospital's risk-adjusted mortality is affected by the severity adjustment method.Data came from 105 acute care hospitals nationwide that use the Medis-Groups severity measure. The study population was 18,016 adults hospitalized in 1991 for pneumonia. Multivariable logistic models to predict in-hospital death were computed separately for 14 severity methods, controlling for patient age, sex, and diagnosis-related group (DRG). For each hospital, observed-to-expected death rates and z scores were calculated for each severity method.The overall in-hospital death rate was 9.6%. Unadjusted mortality rates for the 105 hospitals ranged from 1.4% to 19.6%. After adjusting for age, sex, DRG, and severity, 73 facilities had observed mortality rates that did not differ significantly from expected rates according to all 14 severity methods; two had rates significantly higher than expected for all 14 severity methods. For 30 hospitals, observed mortality rates differed significantly from expected rates when judged by one or more but not all 14 severity methods. Kappa analysis showed fair to excellent agreement between severity methods.The 14 severity methods agreed about relative hospital performance more often than expected by chance, but perceptions of individual hospitals' mortality rates varied using different severity adjustment methods for almost one third of facilities. Judgments about individual hospital performance using different severity adjustment approaches may reach different conclusions.

摘要:

One widely discussed response to the severe problems faced by many rural hospitals is to convert them into organizations that provide health services other than general, acute inpatient care. This study identifies conversions that occurred nationally from 1984 to 1991. The study also empirically examines the determinants of conversion, using rural hospitals that did not convert (between 1984 and 1991) as a comparison group. The authors examine a set of factors that makes radical organizational change necessary (eg, poor performance) and reduces resistance to such change (eg, proximity to other hospitals). Results from discrete-time logistic regression show that converters are more likely than nonconverters to: have poor performance and fewer beds; be located very near to or very distant from similar hospitals; operate in larger communities; devote more of their care to areas other than acute inpatient care; and be members of multihospital systems. Converters also are less likely to be government owned. The need for future research on the effects of conversion is discussed.

摘要:

To assess the health values of patients infected with human immunodeficiency virus (HIV) and examine the relationships between their health values and health status at two points in time, the authors sought to determine whether patients' physical and mental health statuses were good predictors of how they valued their current state of health.One hundred thirty-nine patients with various stages of HIV infection were interviewed in a prospective cohort study based in a primary care practice of a community-based teaching hospital. Patients were interviewed twice at 6-month intervals using three health value measures—the time trade off, rating scale, and Quality of Well-being Scale—and three health status measures: the 18-item Mental Health Inventory, the Dyspnea-Fatigue Index, and the Medical Outcomes Study SF-36 Health Survey.The health status of HIV-infected patients was compromised and, with the exception of mental health, generally was worse among patients with more advanced HIV-infection. Rating scale and Quality of Well-being Scale scores were related inversely to disease stage, but time-trade off scores generally were higher regardless of disease stage. Health value measures showed moderate relationships with measures of physical functioning (r= 0.34 - 0.68) but only a fair relationship with mental health (r= 0.00 - 0.48). The health status of HIV-infected patients who remained asymptomatic or remained symptomatic but without developing acquired immunodeficiency syndrome (AIDS) changed little over 6 months, whereas the health status of patients with AIDS and of patients manifesting progression of HIV-infection deteriorated over time. In contrast, health values, particularly time-tradeoff scores, remained stable even in the face of changes in health status and disease progression. With the exception of mental health, the impact of HIV infection on health status tends to parallel the clinical stage of disease. Health values of HIV-infected patients, however, generally are high and correlate better with physical functioning than with mental health.

摘要:

This article examines the relative importance of occupational, epidemiologic, and attitudinal factors in hepatitis B vaccine acceptance. A stratified random sample of 1,018 health care workers at risk for occupational blood exposure at our university hospital were contacted in 1992 and 919 (90%) participated. Potential reasons for vaccine acceptance or refusal were evaluated with factor analysis. Logistic regression models were calibrated on a stratified random subsample to identify independent predictors of initiating and completing the series, then validated on the remaining subjects. Fifty-four percent (482 of 898) of previously nonimmune workers had completed the series, while 70% (626) had received one or more doses. Hepatitis B vaccine acceptance was related strongly to social influence (physicians, supervisors, role models, friends, and spouse) and knowledge of the disease and vaccine, whereas refusal was primarily related to concern about vaccine side effects and problems with vaccine access. Independent predictors of initiating the vaccine series included younger age (odds ratio [OR] 0.98 per year, 95% confidence interval [CI95] 0.96-0.997), occupation (housestaff: OR 2.9, CI951.1-7.9; nurses; OR 2.1, CI951.0-4.3 versus housekeepers), increased blood exposure frequency (OR 2.4, CI951.6-3.5 for 1-6 versus 0 exposures in past year), and increased frequency of recent influenza vaccination (OR 3.3, CI952.0-5.3 for 1 versus 0 doses in prior 3 years). Occupation (increased acceptance among housestaff, nurses, nursing assistants, laboratory technicians), increased frequency of blood exposure, and recent influenza vaccination also were predictors of series completion.Factors such as occupation, blood exposure frequency and acceptance of other preventive services may help identify health care worker groups with low vaccine acceptance most likely to benefit from targeted vaccine delivery. Hepatitis B vaccine should be offered routinely during evaluation for occupational blood exposure. Future vaccine implementation efforts should emphasize the involvement of physicians and supervisors and education about occupational disease risk, liability, and the safety of the vaccine.

摘要:

Comorbidity generally is measured by medical record abstraction, which is expensive and often impractical. The aim of this study was to assess the reproducibility and validity of a comorbidity questionnaire. The authors developed a brief comorbidity questionnaire that included items corresponding to each element of the medical record-based Charlson index. The questionnaire was administered to 170 inpatients. Charlson scores were abstracted from these patients' medical records. We assessed test-retest reliability of the questionnaire and the Charlson index, the correlation between the questionnaire and the Charlson index, and correlations between each comorbidity measure and indicators of health resource utilization including medication use, hospitalizations in the past year, and hospital charges. Test-retest reliability, assessed with the intraclass correlation coefficient, was 0.91 for the questionnaire and 0.92 for the chart-based Charlson index. The Spearman correlation between these two measures was 0.63. The correlation between comorbidity measures was weaker in less educated patients. Correlations with indicators of resource utilization were similar for the two comorbidity instruments. The authors found that a questionnaire version of the Charlson index is reproducible, valid, and offers practical advantages over medical record-based assessments.

摘要:

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.
