Audit of bronchial artery embolisation in a specialist respiratory centre.
(1/293)
OBJECTIVE: To audit the use of bronchial arteriography and embolisation for controlling haemoptysis. DESIGN: Retrospective review of radiological and clinical data. SETTING: Brompton and National Heart Hospitals. PATIENTS: 35 patients with severe pulmonary disease in whom 58 bronchial arteriograms were obtained between 1 January 1984 and 31 December 1989 with the intention of bronchial artery embolisation for controlling haemoptysis. MAIN MEASURES: Rate of technical success and cessation of haemoptysis; detailed evaluation of patients, particularly those with major haemoptysis (> 100 ml expectorated blood); and retrospective assessment of the appropriateness of the procedure in each. RESULTS: 58 procedures were performed, nine of which were unsuitable for detailed analysis. Nine procedures were for minor haemoptysis, which subsequently recurred, and 40 for recent major haemoptysis in 26 patients with cystic fibrosis (16) aspergilloma (six), bronchiectasis (three), and an unknown diagnosis (one). The median total volume of haemoptysis in the episode before the procedure was 680 ml (range 270-2200 ml). Embolisation was technically successful in 33/40 procedures, in 17 of which, however, major haemoptysis recurred within 10 days of the procedure, leaving 16 clinically and technically successful procedures in 15 patients. Five patients (three with aspergilloma, two with cystic fibrosis) died of haemoptysis despite attempted embolisation. CONCLUSION: Success rate of bronchial artery embolisation was 40%(16/40). IMPLICATIONS: Bronchial artery embolisation is probably not justified for minor haemoptysis or when performed more than one week after a major haemoptysis. Repeat arteriograms during a single period of haemoptysis are seldom useful. With these criteria 43% fewer procedures would have been performed with no loss of clinical benefit. (+info)
Comparison of measures to assess outcomes in total hip replacement surgery.
(2/293)
OBJECTIVES: To compare the performance of a disease specific and a general health questionnaire in assessing changes resulting from total hip replacement. DESIGN: Two stage prospective study of patients undergoing total hip replacement surgery involving an assessment at a clinic before and six months after surgery. 60(32%) patients were followed up by post. SETTING: Outpatient departments at a specialist orthopaedic hospital and peripheral clinics within Oxfordshire. PATIENTS: 188 patients admitted for unilateral total hip replacement between February and mid-August 1994. MAIN MEASURES: Patients' self assessed scores with the 12 item Oxford hip score and SF-36 general health questionnaire together with surgeons' assessment with Charnley hip score obtained before and again at six months after surgery. RESULTS: 186 patients were followed up six months after total hip replacement; a subsample (n=60) by post. Of the 60 postal patients, 59(98.3%) fully completed the Oxford hip score compared with 44(73.3%) who fully completed the SF-36. For the followup sample as a whole, post operative changes in scores produced a large effect size of 2.75 on the Oxford hip score, compared with -1.89 physical function (SF-36), -2.13 pain (SF-36). With the exception of physical function and role (physical), postoperative SF-36 scores were shown to be similar to or better than those found by two population surveys on patients of comparable age. The responsiveness of a disease specific questionnaire, the Oxford hip score, and relevant sections of a general questionnaire, SF-36, were found to be similar as assessed by three different criteria. CONCLUSIONS: A disease specific questionnaire, the Oxford hip score, and a general state of health questionnaire, SF-36, performed similarly in assessing outcomes of total hip replacement except that the disease specific questionnaire resulted in a higher completion rate and greater responsiveness in some sections. On the other hand the general health questionnaire drew attention to broader problems of physical function not considered by the Oxford hip score. The health questionnaires examined here offer a valid and practical means of monitoring outcomes of hip replacement surgery. (+info)
Impact of new guidelines on physicians' ordering of preoperative tests.
(3/293)
OBJECTIVE: To compare the number of preoperative tests ordered for elective ambulatory surgery patients during the 2 years before and the 2 years after the establishment of new hospital testing guidelines. MEASUREMENTS: The patterns of preoperative testing by surgeons and a medical consultant during the 2 years before and the 2 years after the establishment of new guidelines at one orthopedic hospital were reviewed. All tests ordered preoperatively were determined by review of medical records. Preoperative medical histories, physical examinations, and comorbidities were obtained according to a protocol by the medical consultant (author). Perioperative complications were determined by review of intraoperative and postoperative events, which also were recorded according to a protocol. MAIN RESULTS: A total of 640 patients were enrolled, 361 before and 279 after the new guidelines. The mean number of tests decreased from 8.0 before to 5.6 after the new guidelines ( p =.0001) and the percentage decrease for individual tests varied from 23% to 44%. Except for patients with more comorbidity and patients receiving general anesthesia, there were decreases across all patient groups. In multivariate analyses only time of surgery (before or after new guidelines), age, and type of surgery remained statistically significant ( p =.0001 for all comparisons). Despite decreases in surgeons' ordering of tests, the medical consultant did not order more tests after the new guidelines ( p =.60) The majority of patients had no untoward events intraoperatively and postoperatively throughout the study period, with only 6% overall requiring admission to the hospital after surgery, mainly for reasons not related to abnormal tests. Savings from charges totaled $34,000 for the patients in the study. CONCLUSIONS: Although there was variable compliance among physicians, new hospital guidelines were effective in reducing preoperative testing and did not result in increases in untoward perioperative events or in test ordering by the medical consultant.

The effect of the volume of procedures at transplantation centers on mortality after liver transplantation.
(4/293)
BACKGROUND AND METHODS: For many complex surgical procedures there is an association between a low volume of procedures and an increased risk of death for the patients who undergo the procedures. We examined the effect of the volume of procedures at transplantation centers on the risk of death after liver transplantation. We analyzed all liver transplantations performed in the United States between October 1, 1987, and April 30, 1994. Because the results for 1987 to 1991 were largely similar to those from 1992 to 1994, we focused on the more recent period. RESULTS: Between January 1, 1992, and April 30, 1994, 47 centers performed 20 or fewer liver transplantations each per year (total, 837 transplantations) and were designated low-volume centers, and 52 centers performed more than 20 transplantations each per year (total, 6526) and were designated high-volume centers. The one-year mortality rate for the low-volume centers was 25.9 percent, as compared with 20.0 percent for the high-volume centers. Thirteen centers, all of which had low volumes, had one-year mortality rates of more than 40 percent. Low-volume centers that were affiliated with high-volume centers, such as pediatric transplantation programs, had results similar to those of the high-volume centers. The one-year mortality rate at unaffiliated low-volume centers was 28.3 percent, as compared with a rate of 20.1 percent for the group of all high-volume centers plus affiliated low-volume centers (P<0.001). CONCLUSIONS: As a group, liver-transplantation centers in the United States that perform 20 or fewer transplantations per year have mortality rates that are significantly higher than those at centers that perform more than 20 transplantations per year. Information regarding the outcome of liver transplantation at transplantation centers should be made widely available to the public in a timely manner. (+info)
Trends in special (high-security) hospitals. 1: Referrals and admissions.
(5/293)
BACKGROUND: Special hospitals in England provide psychiatric care and treatment in high security. Their future is often questioned. AIMS: To test for variation in demand for high-security psychiatric services over one 10-year period. METHOD: This study was from the special hospitals' case registers and hospital records. The main measures were numbers and annual rates for referrals and beds offered; the Mental Health Act 1983 (MHA) classification of mental disorder; adjusted population rates by health region; admission episodes; legal category of detention; admission source and type of offence. RESULTS: Referrals to special hospitals showed no decrease during the 10 years; an apparent increase may reflect underrecording before 1992. Admissions fell by about 16% over the 10 years, but with regional variation. Women, civil cases, admissions under the MHA classifications of psychopathic disorder or mental impairment and directly from a court on a hospital order were most affected. There was an increase in admissions of pre-trial and sentenced male prisoners, and of transferred hospital order patients from other hospitals. CONCLUSIONS: There is continuing demand from all parts of the country for high-security hospital beds. The smaller numbers admitted appear to include more demanding cases. (+info)
Trends in special (high-security) hospitals. 2: Residency and discharge episodes, 1986-1995.
(6/293)
BACKGROUND: It has been argued that many patients in special hospital beds do not need to be there. In the 1990s there were initiatives to discharge women and people with learning difficulties. AIMS: To test for trends in special hospital discharges and to examine annual resident cohorts. METHOD: This study was from case registers and hospital records. The main measures were numbers and annual rates for referrals and beds offered; the Mental Health Act 1983 (MHA) classification of mental disorder; adjusted population rates by region; admission episodes; legal category of detention; admission source and type of offence. RESULTS: The median annual number of residents was 1859 (range 1697-1910), with an 8% fall for the period. This particularly affected people in mental impairment categories. Numbers were sustained in the male mental illness groups. Discharges, mainly to other institutions, increased. There was no overall change over the 10 years in length of stay for treatment, but successive admission cohorts from 1986 did show some reduction, even with solely remand order cases excluded. CONCLUSIONS: Service planners need a longitudinal perspective on service use. Trends over 10 years to both fewer admissions and more discharges have reduced the special hospital population, but despite new treatments for schizophrenia, men under mental illness classification, as well as transfer from other secure settings, have gone against this trend.

Inpatient care of mentally ill people in prison: results of a year's programme of semistructured inspections.
(7/293)
OBJECTIVE: To investigate the facilities for inpatient care of mentally disordered people in prison. DESIGN: Semistructured inspections conducted by doctor and nurse. Expected standards were based on healthcare quality standards published by the Prison Service or the NHS. SETTING: 13 prisons with inpatient beds in England and Wales subject to the prison inspectorate's routine inspection programme during 1997-8. MAIN OUTCOMES MEASURES: Appraisals of quality of care against published standards. RESULTS: The 13 prisons had 348 beds, 20% of all beds in prisons. Inpatient units had between 3 and 75 beds. No doctor in charge of inpatients had completed specialist psychiatric training. 24% of nursing staff had mental health training; 32% were non-nursing trained healthcare officers. Only one prison had occupational therapy input; two had input from a clinical psychologist. Most patients were unlocked for about 3.5 hours a day and none for more than nine hours a day. Four prisons provided statistics on the use of seclusion. The average length of an episode of seclusion was 50 hours. CONCLUSION: The quality of services for mentally ill prisoners fell far below the standards in the NHS. Patients' lives were unacceptably restricted and therapy limited. The present policy dividing inpatient care of mentally disordered prisoners between the prison service and the NHS needs reconsideration. (+info)
The Bristol shared care glaucoma study: outcome at follow up at 2 years.
(8/293)
AIM: To examine the outcome of care for patients with glaucoma followed up by the hospital eye service compared with those followed up by community optometrists. METHODS: A randomised study with patients allocated to follow up by the hospital eye service or community optometrists was carried out in the former county of Avon in south west England. 403 patients with established or suspected primary open angle glaucoma attending Bristol Eye Hospital and meeting defined inclusion and exclusion criteria were studied. The mean number of missed points on visual field testing in the better eye (using a "better/worse" eye analysis) in each group were measured. The visual field was measured using the Henson semiautomated central field analyser (CFA 3000). Measurements were made by the research team on all patients at baseline before randomisation and again 2 years after randomisation. The mean number of missed points on visual field testing in the worse eye, mean intraocular pressure (mm Hg), and cup disc ratio using a "better/worse" eye analysis in each group at 2 years were also measured. Measurements were made by the research team on all patients at baseline before randomisation and again 2 years after randomisation. An analysis of covariance comparing method of follow up taking into account baseline measurements of outcome variables was carried out. Additional control was considered for age, sex, diagnostic group (glaucoma suspect/established primary open angle glaucoma), and treatment (any/none). RESULTS: From examination of patient notes, 2780 patients with established or suspected glaucoma were identified. Of these, 752 (27.1%) fulfilled the entry criteria. For hospital and community follow up group respectively, mean number of missed points on visual field testing at 2 year follow up for better eye was 7.9 points and 6.8 points; for the worse eye 20.2 points and 18.4 points. Similarly, intraocular pressure was 19.3 mm Hg and 19.3 mm Hg (better eye), and 19.1 mm Hg and 19.0 mm Hg (worse eye); cup disc ratio at 2 year follow up was 0.72 and 0.72 (better eye), and 0.74 and 0.74 for hospital and community follow up group respectively. No significant differences in any of the key visual variables were found between the two groups before or after adjusting for baseline values and age, sex, treatment, and type of glaucoma. CONCLUSIONS: It is feasible to set and run shared care schemes for a proportion of patients with suspected and established glaucoma using community optometrists. After 2 years (a relatively short time in the life of a patient with glaucoma), there were no marked or statistically significant differences in outcome between patients followed up in the hospital eye service or by community optometrists. Decisions to implement such schemes need to be based on careful consideration of the costs of such schemes and local circumstances, including geographical access and the current organisation of glaucoma care within the hospital eye service.
