Concerns About Lung Cancer Among Prisoners.

Background: Few studies have looked at lung cancer in prisoners, despite this population is possibly at increased risk of malignancy. In a previous study, we found an early onset of lung cancer in prisoners. Thus, the present CARCAN study was aimed at assessing the epidemiological characteristics, management, prognosis, and incidence of lung cancer in prisoners compared to a sample of non-prisoner patients.

[Follow-up of IPSS scoring in teaching hospitals].

Objective: To measure the course of compliance with French practice guidelines concerning the use of the IPSS score in the management of patients with symptomatic benign prostatic hyperplasia (BPH) in a teaching hospital urology department.

Material: Data of this study were derived from the computerized clinical information system of the Centre Hospitalier Lyon Sud. Using the indicator monitoring method, the use of the IPSS score was compared over time, before and after publication of the guideline.

Cost-effectiveness of screening blood donors for hepatitis C and non-A, non-B, non-C hepatitis. The EATHIS Eco Research Group. European Acute Transfusion Hepatitis Interferon Study.

The current approach to screening for hepatitis C and non-A, non-B, non-C hepatitis in French blood transfusion centers involves a combination of a transaminase assay and tests for antibodies to hepatitis B core antigen (anti-HBc) and antibodies to hepatitis C virus (anti-HCV). A decision-analysis model was used to assess the cost-effectiveness ratio of this approach compared to the former approach, which included only transaminase and anti-HBc screening. Cost data were collected by a questionnaire sent to 26 centers throughout France.

[Medical and economic evaluation of donated blood screening for hepatitis C and non-A, non-B, non-C hepatitis].

The aim of this study was to evaluate the cost of hepatitis C and non-A non-B non-C screening strategy in donated blood, currently used in French transfusion centres and to assess the effect in the blood transfusion centres according to the prevalence of the disease and the intrinsec values of tests. This screening strategy was based on alanine aminotransferase assay, and HBc and HCV antibodies detection. In 1993, a survey was conducted in 26 French transfusion centers to estimate the costs of the screening strategy currently used.

[Management of myocardial infarction in the Rhone-Alps area. Are there many variations in practice?].

The aim of this study was to determine the diagnostic and therapeutic strategies after myocardial infarction and to examine variations in medical and surgical practice with respect to the severity of disease, status of the hospital and patients' characteristics. The method used was a prospective study with follow-up at 30 days and 18 months. The subjects came from an exhaustive cohort of all patients admitted to hospital for myocardial infarction during the month of April 1991 in 57 public and private hospitals in the Rhone-Alps region (n = 311).

[Analysis of the medical decision].

Analysis of clinical decision making is a quantitative method using probabilities to evaluate the process in uncertain situations. It provides a model of clinical decision making by integrating experimental and epidemiological data, the opinions of specialists and an assessment of the patient's state of health. There is also a place for the integration of the patients' opinions and of their quality of life.
