Der Bedarf an ambulanter kardiologischer Anschlussrehabilitation in einem grossstädtischen Ballungsgebiet. Ergebnisse des Kölner Modells der ambulanten kardiologischen Rehabilitation--Phase II

Within the Cologne Model (CM) of outdoor cardiac rehabilitation (OCR), phase II investigations about the demand for this form of cardiac rehabilitation (CR) after acute cardiac diseases were carried out in three general hospitals, the cardiological and cardiosurgical university hospitals of Cologne. The subsequent questions were investigated: total number of coronary or cardiac operated patients, number of patients with indication for CR, and number of patients corresponding to the restricted indications of CM (age below 65, low risk patient, no cardiac operation). For these groups the acceptance or refusal of CR was checked. Subsequently a sample of patients corresponding to the criteria of CM or of operated patients were confronted with the additional offer of an OCR. The motivation for the acceptance of rehabilitation in specialized hospitals (ICR), OCR or refusal of each kind of CR was inquired. The acceptance of CR in the different groups varied widely. Whereas operated patients in Cologne accept CR in nearly 100% of cases, this is the case in patients after acute myocardial infarction (AMI) in only 50% and in patients after PTCA without AMI in only 5-6%. The analysis of predictors for acceptance brings about that younger patients prefer CR, and if they do, OCR. Patients with the more serious form of disease prefer ICR. Women accept CR more rarely than men, and if they do, they prefer the hospital form. However, this is less gender specific but consequence of the generally more serious form and later onset of CAD in females. Higher educational as well as occupational status favors acceptance of CR and specially OCR. The suspicions that unmarried people prefer OCR and foreigners ICR could not be generally confirmed. Crucial reasons for the form of CR which is accepted or refused are individual ones. ICR is favored by the wish for more safety and better recuperation. For OCR, the comfortable conditions at home with high social support and/or antipathy against hospitals after long clinical treatment are named. Analysis of demand for OCR demonstrates that between 40% in low risk patients (corresponding to CM criteria) and 20% in more serious cases (operated patients) prefer the outhospital form. From these data an estimation of demand for OCR in areas with high population was carried out.
