A randomized, controlled trial of surgery for temporal-lobe epilepsy.
(17/259)
BACKGROUND: Randomized trials of surgery for epilepsy have not been conducted, because of the difficulties involved in designing and implementing feasible studies. The lack of data supporting the therapeutic usefulness of surgery precludes making strong recommendations for patients with epilepsy. We conducted a randomized, controlled trial to assess the efficacy and safety of surgery for temporal-lobe epilepsy. METHODS: Eighty patients with temporal-lobe epilepsy were randomly assigned to surgery (40 patients) or treatment with antiepileptic drugs for one year (40 patients). Optimal medical therapy and primary outcomes were assessed by epileptologists who were unaware of the patients' treatment assignments. The primary outcome was freedom from seizures that impair awareness of self and surroundings. Secondary outcomes were the frequency and severity of seizures, the quality of life, disability, and death. RESULTS: At one year, the cumulative proportion of patients who were free of seizures impairing awareness was 58 percent in the surgical group and 8 percent in the medical group (P<0.001). The patients in the surgical group had fewer seizures impairing awareness and a significantly better quality of life (P<0.001 for both comparisons) than the patients in the medical group. Four patients (10 percent) had adverse effects of surgery. One patient in the medical group died. CONCLUSIONS: In temporal-lobe epilepsy, surgery is superior to prolonged medical therapy. Randomized trials of surgery for epilepsy are feasible and appear to yield precise estimates of treatment effects. (+info)
Who cares for head injuries?
(18/259)
Patterns of management for head injury in the acute and late stages are reviewed in respect of both mild and severe injuries. Because so many disciplines are involved, continuity of care if often difficult to achieve; and no one discipline is concerned with planning for the care of head injuries in a strategic way. The needs of head-injured patients are defined and suggestions made for improving care by the reorganization of existing facilities. What is most needed is to concentrate on patients with head injuries, both in the acute and in the late stages. Only then can medical, nursing, and paramedical personnel become skilled in dealing with the many problems which such patients present. (+info)
Clinical experience with automatic midline echoencephalography: cooperative study of three neurosurgical clinics.
(19/259)
Computerized midline echoencephalography was developed in order to make the determination of the midline more objective. In a group study involving the neurosurgical clinics in Berlin, Erlangen, and Munich, a total of 1,889 patients with various intracranial diseases was examined by this method. An exact analysis of the results obtained is presented: 18 percent were unsatisfactory. (+info)
Is current information available useful for patients and their families?
(20/259)
Internet has recently evolved as a versatile and influential repository of information including those pertaining to neurosurgery. This study was undertaken to find out whether there is good quality information currently available on the Internet for neurosurgery patients and their families. We surveyed the World Wide Web (www) for information on 5 neurosurgery-terms: pallidotomy, lumbar discectomy, hydrocephlus, glioma and carotid artery aneurysm. We searched the www using Google search-engine for documents related to each of the above terms and then assessed the information contained in the first 30-hits for each term using a simple 4-point grading system. Our study suggests that there is generally a good quantity of good quality information on the Internet for neurosurgery patients and their families. Internet provides an opportunity for patient associations and professional bodies to collaborate to create useful databases to help neurosurgery patients and their relatives. (+info)
Can guidelines impact the ordering of magnetic resonance imaging studies by primary care providers for low back pain?
(21/259)
OBJECTIVE: To compare primary care providers' (PCPs') use of lumbar spine magnetic resonance imaging (MRI) studies and surgical referrals for patients with low back pain (LBP) before and after dissemination of the 1994 Agency for Healthcare Policy and Research (AHCPR) LBP guidelines. DESIGN: Retrospective cohort study. PATIENTS AND METHODS: Computerized audits identified patients with LBP evaluated by PCPs in 1994 or 1996 at a university-affiliated Veterans Affairs medical center who had an MRI order and/or a surgical referral. Research assistants recorded patients' demographic characteristics, LBP-related symptoms, and whether the PCP ordered an MRI and/or a surgery consult. For patients referred to surgery without an MRI, subsequent MRI orders by surgeons were recorded. We compared patient characteristics and utilization patterns for 1994 and 1996 and identified independent predictors of MRI orders. RESULTS: PCPs saw 279 and 261 patients with LBP in 1994 and 1996, respectively. An almost identical number of MRIs were ordered in 1994 (99 by PCPs and 42 by surgeons) and 1996 (105 by PCPs and 32 by surgeons). Nearly 50% of patients meeting AHCPR guidelines underwent an MRI in 1994 or 1996. PCPs more frequently ordered a surgery consult in 1994 than in 1996. Providers were less likely to order an MRI for patients with a previous MRI and more likely to order an MRI for those seen in an urgent visit clinic. Neither year nor meeting AHCPR guidelines predicted MRI ordering. CONCLUSIONS: Orders for MRI did not decrease after education on the guidelines. Limiting MRI orders to only "appropriate" patients would not have changed the observed results. (+info)
To stay or not to stay. The assessment of appropriate hospital stay: a Dutch report.
(22/259)
OBJECTIVE: To adjust the adult-medical Appropriateness Evaluation Protocol (AEP) into a valid and reliable instrument for use in the Dutch health care system, to assess the appropriateness of hospital stay and to identify the causes of inappropriateness. DESIGN: The appropriateness of hospital stay was assessed in a cross-sectional survey on a sample of over 4500 days of stay using a modified, Dutch version of the Appropriateness Evaluation Protocol (D-AEP). SETTING: The appropriateness of stay was assessed in five internal and surgical departments for adult acute care in the University Hospital of Maastricht, a 700-bed hospital with a teaching and regional function, located in the southern part of the Netherlands. RESULTS: The results showed that over 20% of the hospital stay was inappropriate. Half of the inappropriate hospital stay (45.1%) was due to (internal) hospital procedures. The D-AEP proved to be valid (kappa = 0.76; 95% confidence interval (95% CI) 0.68-0.84), reliable (kappa = 0.84; 95% CI 0.75-0.93) and easy to use. CONCLUSION: A substantial proportion of hospital stay was found to be inappropriate, due to hospital procedures and the inability to refer patients to other care facilities or care providers. The D-AEP can be used for monitoring the appropriate hospital stay and in detecting possible causes of inappropriate stay. Analysis of the causes of inappropriate hospital stay provided useful data for improvement actions. (+info)
Cost analysis of a project to digitize classic articles in neurosurgery.
(23/259)
In summer 2000, the Cushing/Whitney Medical Library at Yale University began a demonstration project to digitize classic articles in neurosurgery from the late 1800s and early 1900s. The objective of the first phase of the project was to measure the time and costs involved in digitization, and those results are reported here. In the second phase, metadata will be added to the digitized articles, and the project will be publicized. Thirteen articles were scanned using optical character recognition (OCR) software, and the resulting text files were carefully proofread. Time for photocopying, scanning, and proofreading were recorded. This project achieved an average cost per item (total pages plus images) of $4.12, a figure at the high end of average costs found in other studies. This project experienced high costs for two reasons. First, the articles contained many images, which required extra processing. Second, the older fonts and the poor condition of many of these articles complicated the OCR process. The average article cost $84.46 to digitize. Although costs were high, the selection of historically important articles maximized the benefit gained from the investment in digitization. (+info)
The internet.
(24/259)
The growing use of email and the world wide web (WWW), by the public, academics, and clinicians-as well as the increasing availability of high quality information on the WWW-make a working knowledge of the internet important. Although this article aims to enhance readers' existing use of the internet and medical resources on the WWW, it is also intelligible to someone unfamiliar with the internet. A web browser is one of the central pieces of software in modern computing: it is a window on the WWW, file transfer protocol sites, networked newsgroups, and your own computer's files. Effective use of the internet for professional purposes requires an understanding of the best strategies to search the WWW and the mechanisms for ensuring secure data transfer, as well as a compendium of online resources including journals, textbooks, medical portals, and sites providing high quality patient information. This article summarises these resources, available to incorporate into your web browser as downloadable "Favorites" or "Bookmarks" from www.jnnp.com, where there are also freely accessible hypertext links to the recommended sites.
