Neodymium:YAG laser posterior capsulotomies performed by residents at a Veterans Administration Hospital.

PURPOSE: To assess the initial efficacy of neodymium:YAG (Nd:YAG) laser posterior capsulotomies performed by residents at a teaching institution and to evaluate the associated complications over an extended follow-up. SETTING: Department of Ophthalmology, Edward Hines, Jr. Veterans Administration Hospital, Hines, Illinois, USA. METHODS: This retrospective noncomparative case review comprised 212 pseudophakic eyes having Nd:YAG laser posterior capsulotomies from April 1992 through March 1995. Evaluated were postoperative changes in best corrected visual acuity (BCVA), intraocular pressure (IOP) elevations, and complications related to the procedure. RESULTS: In all 212 eyes, Snellen visual acuity was obtained at least 1 week after the capsulotomy. The BCVA in 96 eyes (45.3%) improved by 3 or more lines, in 43 (20.3%) by 2 lines, and in 51 (24.1%) by 1 line. Nineteen eyes (9.0%) did not improve by 1 or more lines, and 3 eyes (1.4%) had decreased Snellen acuity. All but 4 eyes with less than 1 line of improvement had underlying ocular pathology or a previous incomplete capsulotomy. For evaluation of postoperative complications, long-term follow-up was available for 133 of 212 eyes (62.7%). The mean follow-up for this group was 3.18 years. Postoperative complications were found in 14 of these eyes (10.5%). Nine (6.8%) had a rise in IOP greater than 10 mm Hg after the capsulotomy. One eye (0.8%) developed a persistent iritis, 2 (1.5%) had vitreous prolapse into the anterior chamber, and 2 (1.5%) developed rhegmatogenous retinal detachments. CONCLUSION: Postoperative Snellen acuity results and complication rates compare favorably with those in previous studies. The results indicate that Nd:YAG laser posterior capsulotomies performed by residents with attending supervision are safe, effective, and carry a low associated complication rate over a long follow-up.

An efficiency analysis of Veterans Health Administration hospitals.

This study evaluates the efficiency of Veterans Health Administration (VHA) hospitals using a variable-returns to scale, input-oriented, data envelopment analysis method. Hospital executives, health care policymakers, taxpayers, and ultimately the veteran patient population benefit from studies that look to improve the efficiency of the VHA. Data for 131 VHA hospitals in 1998 and 121 in 2001 were analyzed by using data envelopment analysis to measure hospital efficiency. The results indicated that efficiency in VHA hospitals improved from 85% in 1998 to 86% in 2001. Although this level of efficiency is commendable, the study documents potential savings through more efficient use of resources. From a management perspective, this study shows opportunities for improved management and the realignment of resources to better meet demand. From a policy perspective, the study highlights the political problems associated with improving efficiency and providing access to critical health care services.

Management science models for microcomputers in hospital administration.

Use of microcomputer programs for management engineering in hospitals reduces the chore of operational planning at very low cost. This article describes some management information systems available for microcomputers and provides an example run-through to show how one such system can be used to schedule patients for surgery.

Nosocomial infection rates during a one-year period in a nursing home care unit of a Veterans Administration hospital.

Infections in long-term care institutions are a constant source of morbidity in residents in these facilities. We report our experience with infection rates during a 1-year surveillance period in a 120-bed nursing home care unit of a Veterans Administration hospital. Our purpose was (1) to establish our own infection rate and (2) to ascertain the relationships (a) between infection rate and level of required nursing care and (b) between infection rate and staffing adequacy. Our overall nosocomial infection rate for 1987 was 4.6 infections/1000 patient days. The majority of infections were urinary tract infections, with the predominant pathogen Proteus mirabilis. One ward in the nursing home care unit had a significantly higher infection rate compared with that of the other wards (p less than 0.05), and there was a significantly higher infection rate in residents who required total nursing care versus less dependent residents (p less than 0.05). We were unable to find a direct relationship between the degree of staff shortages and infection rate. This prolonged infection control surveillance indicated our nosocomial infection rates were similar to those in previously published reports. We also identified problem infections in certain areas, which led us to develop staff in-service programs to address these problems. In summary, we believe this information is useful not only for us but for others involved in the care of residents in long-term care facilities inasmuch as there are little published data on yearly infection rates per patient days.

Roles of hospital administrators in South Carolina.

Using discriminant analyses of data on 916 returned questionnaires from a mailing to 1,650 administrators in 82 South Carolina hospitals, this study examines the allocation of interpersonal, informational, decisional, and treatment roles among executive, administrative, and clinical directors. Educational attainment, years of experience, and gender were found to influence respondents' positions. Results also indicate that executive directors assume responsibility for the organization and its relation to the environment. As expected, those in clinical and administrative positions assume more responsibility for interpersonal and treatment roles than do executive directors.

HAART adherence in culturally diverse patients with HIV/AIDS: a study of male patients from a Veteran's Administration Hospital in northern California.

The objective of this study was to identify the factors that influence adherence to antiretroviral medication regimens in culturally diverse populations with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) related to age, ethnicity, and intravenous drug use. The critical incident technique was used to identify factors determining adherence. Through a series of brief, focused interviews, patients were asked to recall specific incidents that affected their adherence to HIV medications. Patients' responses were grouped into categories using Ethnograph software. Two nurse experts, with 94% agreement, determined the reliability of the category listings. A chi(2) analysis compared the proportion of patients reporting each factor across age, ethnicity, and intravenous drug use categories. The total sample of 52 participants included 46 male outpatients with HIV/AIDS receiving care through a Veteran's Administration Hospital in northern California and 6 health care providers. The interviews yielded a total of 294 incidents. Six major categories were identified, and a taxonomy of critical factors determining highly active antiretroviral therapies (HAART) adherence was developed. The categories included reminders and cues (30%), planning (18%), response to HIV/AIDS (17%), HIV medication characteristics (14%), interactions with others (12%), and patient characteristics (10%). The two largest categories representing patient-related factors accounted for nearly half of the incidents. Patients most influenced by positive support from others included non-Caucasians, those under the age of 50 years, and those with fewer years of education. The taxonomy of adherence behaviors provides important information for developing culturally relevant patient adherence education programs and an essential foundation for developing future studies.
