The surgical risk of colectomy in patients with cirrhosis

The records of 54 patients with documented cirrhosis who underwent colectomy between January 1970 and January 1984 were studied to assess the operative risk and to determine the preoperative predictive risk factors. In-hospital mortality was 24 percent (13 patients), and postoperative complications occurred in 48 percent (26 patients). The risk of surgical intervention was significantly increased if encephalopathy, ascites, anemia, or hypoalbuminemia was present before operation. A simple operative risk index involving the presence of encephalopathy and ascites and the levels of hemoglobin and albumin is proposed to help distinguish a low-risk subgroup in whom postoperative mortality was 12.8 percent from a high-risk subgroup in whom postoperative mortality was 53.3 percent.     

BUILDING COMMUNITY: Developing Skills for Interprofessional Health Professions Education and Relationship-Centered Care

In 1995, the National League for Nursing commissioned a Panel on Interdisciplinary/Transdisciplinary Education. The focus of the Panel's work was to examine educational issues that transcend the health professions and to make recommendations for future implementation of an interdisciplinary approach to addressing them. This article is being simultaneously published by several professional journals. The goal is to seek as much feedback as possible.     

'This isn't very typical I'm afraid': observing community care complaints procedures

The new complaints procedures which local authority social services departments have been required to introduce represent an important mechanism for managing the change of culture associated with recent community care reforms. They also represent a new genre in mechanisms of redress for welfare recipients. This paper reports the findings of a study which has observed considerable diversity in the ways in which local authorities are interpreting the nature and purposes of the new procedures and, in particular, the functions of review panels established under those procedures. Variations in the composition of panels, in the style of review panel proceedings, in perceptions of the panels' powers, and in the ways that complaints and complainants are constituted are all discussed. Attention is drawn to four competing interpretations of the review panels' role and to the need for these to be clarified and prioritised.     

INTERACTIONS BETWEEN THE CIRCULATORY EFFECTS OF CENTRAL HYPOVOLAEMIA AND ARTERIAL HYPOXIA IN CONSCIOUS RABBITS

1. Eight conscious rabbits were repeatedly subjected to progressive reduction in central blood volume by gradually inflating a thoracic inferior vena caval-cuff so cardiac index (CI) fell at a constant 8.5% of baseline/min. 2. Caval-cuff inflations were performed after 10 min exposure to 100, 21, 12–14 and 8–10% O₂, with and without the addition of 3–4% CO₂, in randomized order. 3. The haemodynamic response to progressive reduction in central blood volume was biphasic. In Phase I, systemic vascular conductance index (SVCI) fell linearly, supporting mean arterial pressure (MAP). When CI had fallen to a critical level, Phase II occurred in which SVCI rose abruptly, MAP plummeted and respiratory drive progressively increased. 4. During Phase I, there were independent linear relationships between Pao₂ (but not Pao₂) and the rates at which SVCI and MAP changed during the progressive fall of CI. The higher the level of Pao₂, the greater was the rate of fall of SVCI and the less the rate of fall of MAP. 5. There was an inverted U-shaped effect of Pao₂, on the level of CI at which Phase II occurred: (a) during hyperoxia (100% O₂), Phase II occurred later than during normoxia (21% O₂); and (b) across the normoxic and hypoxic gas mixtures (21–8% O₂, with and without added CO₂), there was an independent linear relationship between Pao₂ (but not Pao₂ or Pao₂×Pao₂) and the level of CI at which Phase II occurred. That is, the lower the level of Pao₂, the later was the onset of Phase II. This interaction is best explained by an increased level of central sympathetic vasoconstrictor drive during hypoxia.     

Rural Hospital Inpatient Surgical Volume: Cutting-edge Service or Operating on the Margin?

Surgical services are an important part of modern health care, but providing them to isolated rural citizens is especially difficult. Public policy initiatives could influence the supply, training, and distribution of surgeons, much as they have for rural primary care providers. However, so little is known about the proper distribution of surgeons, their contribution to rural health care, and the safety of rural surgery that policy cannot be shaped with confidence. This study examined the volume and complexity of inpatient surgery in rural Washington state as a first step toward a better understanding of the current status of rural surgical services. Information about rural surgical providers was obtained through telephone interviews with administrators at Washington's 42 rural hospitals. The Washington State Department of Health's Commission Hospital Abstract Recording System (CHARS) data provided a count of the annual surgical admissions at rural hospitals. Diagnosis-related group (DRG) weights were used to measure complexity of rural surgical cases. Surgical volume varied greatly among hospitals, even among those with a similar mix of surgical providers. Many hospitals provided a limited set of basic surgical services, while some performed more complex procedures. None of these rural hospitals could be considered high volume when compared to volumes at Seattle hospitals or to research reference criteria that have assessed volume-outcome relationships for surgical procedures. Several hospitals had very low volumes for some complex procedures, raising a question about the safety of performing them. The leaders of small rural hospitals must recognize not only the fiscal and service benefits of surgical services--and these are considerable--but also the potentially adverse effect of low surgical volume on patient outcomes. Policies that encourage the proper training and distribution of surgeons, the retention of basic rural surgical services, and the rational regionalization of complex surgery are likely to enhance the convenience and safety of surgery for rural citizens.     

Adhesive capsulitis: evaluation of a treatment coupling capsular distension and intensive rehabilitation]

INTRODUCTION: Adhesive capsulitis is a clinical entity characterized by a loss of motion and a decrease of the joint volume capacity. Results of clinical trials have shown that distensions can help to decrease pain and increase the range of motion. OBJECTIVE: The purpose of the study was to measure the effect of repeated distension arthrography combined with an intensive program of rehabilitation on pain, range of motion, and occupational outcome in patients with adhesive capsulitis. DESIGN: 39 cases of idiopathic capsulitis (7 cases) or secondary capsulitis (19 post-traumatic, 13 post-surgery of the rotator cuff) were included in the study. Intervention consisted of an intensive program of passive and active physiotherapy during one? Week and then distension arthrography, performed 3 times at 1- week intervals, with steroid injections in the glenohumeral joint and 1 in the subacromial space. RESULTS: Lateral elevation improved substantially after the first week of physiotherapy and medial rotation after the first distension. Pain intensity decreased after the first distension. After the third distension, very small changes were noted. Results did not differ by etiology of capsulitis. At the end of the program, 9 of 17 patients could return to their previous job. CONCLUSIONS: Two repeated arthrographic distensions with steroid injection and an intensive program of physiotherapy improves the range of motion and the painful condition associated with capsulitis and allows for a rapid return to employment. A third distension does not seem to provide a further benefit, as has been found by other studies.     

General case simulation instruction and the establishment and maintenance of work performance

This study was conducted to determine whether general case simulation instruction on selected job task sequences and teaching examples, which sampled the range of stimulus/response variation encountered in two community jobs, resulted in the generalized performance of specific community job requirements by four young adults with severe handicaps. A multiple baseline across subjects and behaviors design was used to assess subject performance in simulation instruction, on concurrent and subsequent actual job probes, and in actual job instruction. Data indicated that simulation instruction on two representative teaching examples for each of two job task sequences resulted in concurrent generalized performance on six response examples for each task sequence, and in subsequent improvements in job entry skills which were maintained and extended during actual job instruction and instructor withdrawal phases. Results are discussed in terms of potential uses and misuses of general case simulations of community job skills.
