Evaluating a computer-based experiential learning simulation: a case study using criterion-referenced testing.

Abstract

A case study of a computer-based experiential learning program involving the use of criterion-referenced testing as a quantitative evaluation tool is described. The simulation was designed to introduce nurses to basic computer operations. One hundred and thirty-eight nurses participated in the evaluation using a specially prepared version of the program that recorded the time required to perform actions, the number of unsuccessful attempts to complete instructions, and the number of correct responses to specific questions. The ability of the nurses to "drag and drop" increased significantly from less than 20% to more than 90% (p < .05, Student's t-test). Their knowledge of the definitions of four computer-related terms (i.e., trackball, desktop, window, and icon) increased significantly (from 65% to 80%, p < .1). In subjective evaluations, 82% of respondents reported that they enjoyed the lesson and 89% wanted more computer-based instructional units to be developed. Use of criterion-referenced testing helped to shed new light on the utility of such computer aided instructional systems.

Carotid endarterectomy trends in the patterns and outcomes of care at academic medical centers, 1990 through 1995.

OBJECTIVE: To evaluate whether the patterns of inpatient care and patient characteristics have changed for patients undergoing a carotid endarterectomy across a group of academic medical centers from 1990 through 1995. If changes occurred, we investigated whether they had an impact on patient outcomes. DESIGN: Retrospective evaluation of patients undergoing a carotid endarterectomy using a hospital discharge data set compiled by the Academic Medical Center Consortium. SETTING: Ten academic medical centers. PATIENTS: A total of 7019 hospital admissions for patients who had 1 carotid endarterectomy performed as a principal procedure from January 1990 to December 1995. MAIN OUTCOME MEASURES: Trends in patient demographics, comorbidities, length of stay, days in the intensive care unit, and inpatient cerebral arteriogram use were determined. Patient outcomes included inpatient mortality, discharge to an institution, 30-day readmission rate, and selected diagnoses (postoperative hemorrhage, infection, or seizure; acute myocardial infarction; or cranial nerve palsy) and postprocedure diagnostic tests (computed tomography and magnetic resonance imaging of the head and electroencephalogram) indicative of complications. RESULTS: Over the 6-year study period, the number of carotid endarterectomies performed more than doubled and the percentage of hospital admissions for patients 65 years or older increased from 65% to 75%. The mean and median length of stay halved and the percentage of admissions with transfers to the intensive care unit decreased from 56% to 26% of cases. In addition, the percentage of cases with a cerebral arteriogram during the same admission but prior to the day of the carotid endarterectomy decreased from 52% to 27%. There were no trends in inpatient mortality, discharge to an institution, or 30-day readmission rate. There were no significant trends indicative of poorer quality of care as measured by the frequency of secondary diagnoses or postprocedure diagnostic test use. CONCLUSIONS: Despite dramatic changes that have occurred in patient characteristics and in hospital management practices for patients undergoing a carotid endarterectomy from 1990 to 1995, we were unable to detect any measurable impact on patient outcomes. These data have implications for monitoring and evaluating the impact of systemwide change on the overall quality of care for patients undergoing a carotid endarterectomy.

A comparative evaluation of collaborative prenatal care.

OBJECTIVE: To evaluate the effectiveness of an advanced-practice nurse-obstetrician collaborative prenatal practice. METHODS: A group of 194 consecutively enrolled medically low-risk obstetric patients was identified between January 1, 1994 and December 31, 1994 at Neighborhood Pregnancy Care, a collaborative-practice site. An equal number of medically low-risk patients attending the Louisiana State University obstetric clinic at the Medical Center of Louisiana at New Orleans was selected randomly from among those registering the same month. The two groups were compared on the primary outcome variable, low birth weight. Data were analyzed by chi2, Fisher exact test, t test, and regression models. RESULTS: We compared 179 collaborative-care and 181 university patients with retrievable information. By univariate analysis, collaborative-care patients more often were teenagers and black, and less likely to be married or employed. Collaborative-care patients had more prenatal visits and were more likely to participate in Medicaid, but less likely to deliver at the Medical Center of Louisiana at New Orleans. Birth weight and gestational age at delivery were greater. Both delivery before 37 weeks (7.3% versus 17.7%, P < .001) and birth weight less than 2500 g (8.9% versus 19.3%, P < .001) were less common. When differences identified at the initial obstetric visit were considered, multivariate weighted logistic regression confirmed the importance of prenatal care at the collaborative-practice program for low birth weight (odds ratio [OR] 0.37; 95% confidence interval [CI] 0.19, 0.71) and preterm delivery (OR 0.36; 95% CI 0.16, 0.78). When all differences were entered, low birth weight remained a significantly less likely occurrence at the collaborative-practice site (OR 0.46; 95% CI 0.23, 0.92). CONCLUSION: An advanced-practice nurse-obstetrician collaborative practice may be implemented successfully and lead to acceptable perinatal outcomes, as judged by low birth weight and prematurity.

Changes in charges and costs associated with hospitalization of patients with mandibular fractures between 1991 and 1993.

PURPOSE: The purpose of the study was to examine the changes in costs, charges, and income related to hospitalization of patients with mandibular fractures treated over a 3-year period. PATIENTS AND METHODS: The study involved retrospective analysis of data on 97 patients treated by the Department of Oral and Maxillofacial Surgery between 1991 and 1993. Biographical data were obtained from the Trauma Registry, and the financial data were obtained from the Financial Services Administration. The study examined the changes in costs and charges of hospitalization, insurance status, reimbursement, total revenue, and income losses from hospitalization of patients admitted with a primary diagnosis of mandibular fracture. In addition, the study examined the changes in costs of major items involved in treatment. Possible variables such as age, gender, and cause of fracture were also recorded. RESULTS: Twenty-nine patients were admitted in 1991, 35 in 1992, and 33 in 1993. These patients were predominantly young males. The average cost of treatment decreased by 2% in 1992 and increased by 58% in 1993. The average charge increased by 12.9% in 1992 and by 76.8% in 1993. The total reimbursement increased by 11.2% in 1992 and by 47.7% in 1993. The average payment per patient to the institution by third-party payers decreased by 7.8% in 1992 and increased by 56.6% in 1993. The loss of income to the institution (cost minus reimbursement) increased by 105.9% in 1992 and by 58% in 1993. The average institution income loss from the care for each patient increased by 70.6% in 1992 and by 67.8% in 1993. CONCLUSIONS: This study showed that there was a continued increase in costs, charges, and income loss for hospitalization of mandibular fracture patients during the years 1991 to 1993, whereas the reimbursement rate decreased from 65% to 47% of the charges. The increase in cost of supplies and use of rigid fixation, the increase in the number of uninsured patients, and the pricing practices of the institution were possible causes of these changes.
