Metric properties of the appropriateness evaluation protocol and predictors of inappropriate hospital use in Germany: an approach using longitudinal patient data.
(9/21)
BACKGROUND: The German health care system, renowned for its unrestricted access, high quality care, and comprehensive coverage, is challenged by increasing health care costs. This has been attributed partly to inefficiencies in the in-patient sector, but has been studied little. Attempts at quality improvement need to relate costs to outcomes. Until now, there has been no standardized methodology to evaluate the appropriateness of hospital care. OBJECTIVE: To develop and evaluate the metric properties of a method to assess inappropriate hospital care in Germany based on a widely used measure, the Appropriateness Evaluation Protocol (AEP). METHODS: The original AEP was translated and adapted to reflect differences in the provision of health care in Germany. Psychometric testing was performed in a stratified sample of all patients admitted to the Departments of Medicine and Surgery of a 400-bed teaching hospital during 1 year. Three board-certified physicians participated in each department to evaluate intra-rater reliability, while two additional independent physicians judged inter-rater reliability. RESULTS: Inter-rater agreement for the evaluation of hospital days among surgical patients was 84% (80-87%), with an average kappa value of 0.58 (0.48-0.68). Corresponding figures for patients in medicine were 76% (73-80%) with a K value of 0.42 (0.34-0.42). Inter-rater agreement for hospital admissions and K was 74% (62-86%) and 0.44 (0.21-0.67) in surgery, and 92% (85-100%) and 0.31 (0-0.80) in medicine, respectively. Thirty-three per cent of all admissions and 28% of consecutive hospital days were judged inappropriate in surgery; among medicine patients, reviewers found 6% of admissions and 33% of hospital days inappropriate. Time since admission was the strongest predictor of inappropriate hospital use adjusted for length of stay, comorbidity, age, and gender. (+info)
An exploratory cost analysis of performing hospital-based concurrent utilization review.
(10/21)
OBJECTIVE: To determine the costs associated with conducting concurrent utilization review, a utilization management strategy widely used by the managed care industry. STUDY DESIGN: A production process model focusing on resource utilization. SUBJECTS: The 29 clinical services of a 500-bed academic health center were aggregated into 9 clinical groups. A random sample of at least 15 reviews per group was studied. METHODS: Time sampling and cost analysis methods were used to determine the cost to the hospital of conducting utilization review. Component activities of the process were identified and analyzed to determine differences among clinical services and among the component tasks of the utilization review process. RESULTS: In 12 months, 13 126 reviews were completed in an average of 15 minutes 41 seconds. Across clinical groups, the average total time of each review ranged from 11 minutes 18 seconds (medical group) to 19 minutes 4 seconds (pediatrics group). Significant differences existed among clinical service groups for the activity of preparing for conducting the review, with the pediatrics group spending more time than the cardiology and oncology groups. The total cost of the process was nearly dollar 166 000 annually. The average cost per review was dollar 11, the average cost per patient-day denied was dollar 478, and the average cost per patient denial was dollar 1592. CONCLUSIONS: These figures are conservative in that they do not include the payer component of the costs, which could be as high as the hospital provider cost. Given a denial rate of < 2% and the high cost of the process, it may be beneficial to investigate alternative processes for conducting utilization review. (+info)
Effect of drug utilization reviews on the quality of in-hospital prescribing: a quasi-experimental study.
(11/21)
BACKGROUND: Drug utilization review (DUR) programs are being conducted in Canadian hospitals with the aim of improving the appropriateness of prescriptions. However, there is little evidence of their effectiveness. The objective of this study was to assess the impact of both a retrospective and a concurrent DUR programs on the quality of in-hospital prescribing. METHODS: We conducted an interrupted time series quasi-experimental study. Using explicit criteria for quality of prescribing, the natural history of cisapride prescription was established retrospectively in three university-affiliated hospitals. A retrospective DUR was implemented in one of the hospitals, a concurrent DUR in another, whereas the third hospital served as a control. An archivist abstracted records of all patients who were prescribed cisapride during the observation period. The effect of DURs relative to the control hospital was determined by comparing estimated regression coefficients from the time series models and by testing the statistical significance using a 2-tailed Student's t test. RESULTS: The concurrent DUR program significantly improved the appropriateness of prescriptions for the indication for use whereas the retrospective DUR brought about no significant effect on the quality of prescribing. CONCLUSION: Results suggest a retrospective DUR approach may not be sufficient to improve the quality of prescribing. However, a concurrent DUR strategy, with direct feedback to prescribers seems effective and should be tested in other settings with other drugs. (+info)
Active surveillance using electronic triggers to detect adverse events in hospitalized patients.
(12/21)
BACKGROUND: Adverse events (AEs) occur with alarming frequency in health care and can have a significant impact on both patients and caregivers. There is a pressing need to understand better the frequency, nature, and etiology of AEs, but currently available methodologies to identify AEs have significant limitations. We hypothesized that it would be possible to design a method to conduct real time active surveillance and conducted a pilot study to identify adverse events and medical errors. METHODS: Records were selected based on 21 electronically obtained triggers, including abnormal laboratory values and high risk and antidote medications. Triggers were chosen based on their expected potential to signal AEs occurring during hospital admissions. Each AE was rated for preventability and severity and categorized by type of event. Reviews were performed by an interdisciplinary patient safety team. RESULTS: Over a 3 month period 327 medical records were reviewed; at least one AE or medical error was identified in 243 (74%). There were 163 preventable AEs (events in which there was a medical error that resulted in patient harm) and 138 medical errors that did not lead to patient harm. Interventions to prevent or ameliorate harm were made following review of the medical records of 47 patients. CONCLUSIONS: This methodology of active surveillance allows for the identification and assessment of adverse events among hospitalized patients. It provides a unique opportunity to review events at or near the time of their occurrence and to intervene and prevent harm. (+info)
Hospital-based utilization management: a cross-Canada survey.
(13/21)
Utilization management attempts to measure, understand and, when appropriate, reduce hospital use. We conducted a telephone survey to determine the status of utilization management in Canadian hospitals. The sample comprised a random selection of 30% of acute-care hospitals with over 100 beds for adults in Ontario and Quebec and all such hospitals in the other provinces. Of the 123 chief executive officers contacted 99 (80%) claimed to have a utilization management program. Of those, 90 (91%) agreed to participate in an in-depth survey or to designate a senior administrator to be interviewed who was most knowledgeable about the program. High occupancy rates and funding issues were the most common environmental triggers for the development of utilization management programs; funding issues were listed more frequently by respondents in Ontario than by those elsewhere (p = 0.0008). Retrospective review alone was used in half of the hospitals, concurrent review or some mixed approach being used in the other half. Ontario and the Atlantic provinces were more reliant than the rest of the country on retrospective review alone (p = 0.0032). Most of the hospitals used peer review and education to stimulate corrective action. Of the respondents 67% indicated that the medical staff supported the utilization management program, and 53% reported that the program had a positive impact on the relationship between administrative and medical staff. Most of the respondents were unsure of the program's impact on the quality of care or the rate of unnecessary hospital admission. However, retrospective review alone was found to be less successful in reducing inappropriate utilization than either concurrent review or combined review (p = 0.0048). (+info)
Use of hospital beds: a cohort study of admissions to a provincial teaching hospital.
(14/21)
An instrument was developed to study the use of hospital beds and discharge arrangements of a cohort of 847 admissions to the John Radcliffe Hospital, Oxford, for a three week period during February-March 1986. For only 38% of bed days were patients considered to have medical, nursing, or life support reasons for requiring a provincial teaching hospital bed. The requirements for a bed in the hospital decreased with the patient's age and length of stay in hospital. For only a tenth of patients was the general practitioner concerned in discussions with hospital staff about the patient's discharge and less than one third of patients had been given more than 24 hours' notice of discharge. Several features might increase the proportion of bed days that are occupied by patients with positive reasons for being in hospital. Among these are an increased frequency of ward rounds by consultants, or delegating discharge decisions by consultants to other staff; providing diagnostic related protocols for planning the length of stay in hospital; planned discharges; and providing liaison nurses to help with communication with primary care staff.

The dynamics of utilization review: a case study of 44 Massachusetts hospitals.
(15/21)
Utilization review programs have existed on a national basis for over a decade, but relatively little is known about the patients who are scrutinized and what actions are taken to correct unnecessary use. In the fall of 1976, 44 of the 122 Massachusetts hospitals participated in a two-week in depth study of their utilization review activities. Over 22,000 admission and extended stay reviews were performed during this time period, and of these, 2,120 patients' continued stays in the hospital were questioned. In five admission review cases and 79 extended stay review cases, the UR committee formally terminated continued health insurance benefits, and in 12 admission reviews and 74 extended stay reviews, questioning by the UR committee led the attending physician to discharge the patient earlier than would have otherwise occurred. Ninety-four percent of the terminations occurred in Medicare patients and the median age of these patients exceeded 80 years. For medical patients, a disproportionate share of all those cases questioned and of those terminated occurred in chronic illness categories, such as cancer, heart failure, and organic brain syndromes. A higher than expected percentage of surgical cases questioned by the UR committee were in neurosurgical, cardiovascular and orthopedic procedure groups. The frequency with which UR committees identified and acted upon cases suggests that effective self-policing is occurring. A large portion of the utilization problem, however, may be related to the unavailability of appropriate sub-acute care for patients with chronic medical illness or surgical procedures which require long postoperative rehabilitation and recuperation.

Changes in average length of stay and average charges generated following institution of PSRO review.
(16/21)
A five-year review of accounting data at a university hospital shows that immediately following institution of concurrent PSRO admission and length of stay review of Medicare-Medicaid patients, there was a significant decrease in length of stay and a fall in average charges generated per patient against the inflationary trend. Similar changes did not occur for the non-Medicare-Medicaid patients who were not reviewed. The observed changes occurred even though the review procedure rarely resulted in the denial of services to patients, suggesting an indirect effect of review. (+info)
