title: [The prognostic value of variables from the quality assurance program and of the rehabilitation-discharge report of the LVA Baden-Württemberg for early retirement: results of a retrospective cohort-study].
abstract: Since 1997 the LVA Baden-Württemberg pension insurance agency has implemented an instrument to measure the outcome quality of in-patient rehabilitation. The objective of this study was to evaluate the prognostic value of various short-term rehabilitation success markers and of variables of the quality assurance program and the rehab-discharge report of the LVA Baden-Württemberg on early retirement by means of a retrospective cohort study. The analysis was based on routinely registered data of patients who underwent in-hospital rehabilitation in a hospital accredited by the LVA Baden-Württemberg between June 1997 and June 1999. Baseline data included information from medical discharge reports and from the quality assurance programme. Follow-up information with regard to disability was collected until July 2000. The prognostic value of the quality assurance programme and of 4 standardized documented items from the medical discharge report was estimated by proportional hazards regression. In this analysis 6,823 patients aged 30-59 years who underwent an in-patient rehab programme between June 1997 and July 1999 in 5 of 6 LVA rehab clinics were included. During follow-up (mean duration: 1.8 years) 908 (13.3%) patients retired because of health-related disability. The variables with the strongest prognostic values were the evaluation of the patient health status by the physician and the patients themselves and the capacity to work. The variables with the highest prognostic value were the evaluation on a 1-6 visual analogue scale; a better assessment by one mark of the health status by physician and patient himself, respectively, was associated with a 53% and 40% reduced risk of disability. Fitness for work at discharge was the most prognostic variable from the discharge report. Patients who were able to work had a 78% reduced risk of disability compared to patients unable to work. Also of prognostic relevance were a positive performance and the duration of the inability to work the year before rehabilitation. The variables of the newly developed quality assurance programme of the LVA clearly demonstrated a prognostic value in terms of risk for subsequent early retirement. It should be considered to include the ability to work at discharge in the programme to further improve its prognostic value.
