[Health promotion and inpatient rehabilitation. Long-term effects of education in patients with coronary heart disease].
BACKGROUND AND PURPOSE: The most important goals in the rehabilitation of patients with a coronary heart disease (CHD) include the diagnosis and treatment of risk factors, health promotion, and education. The knowledge on and awareness of cardiovascular risk factors is an important precondition for a high patient compliance. Former studies on patients in cardiologic departments of hospitals showed no effect of health promotion and education on patients' knowledge on risk factors, presumably because of the setting in acute therapy. Therefore, the possible effects of health promotion and education on the knowledge of patients were studied in the setting of an inpatient rehabilitation. METHODS: Over 1 year, 426 patients, admitted to an inhospital rehabilitation, were questioned on the first and last day of their stay using a validated instrument ("Bochumer Bewertungsbogen-Kardiovaskuläre Risikofaktoren" [BBKR], Table 1). 1 year after discharge, the same questionnaire was sent to the surviving 423 patients. Of these, 267 patients (63.1%) answered. The average age was 64.3 years (standard deviation [SD] 11.3). Demographic data and clinical history are summarized in Table 2. RESULTS: For most of the known risk factors of CHD, the number of patients mentioning them significantly increased during the observation period. On the day of admittance, only 59.2% mentioned diabetes mellitus as a risk factor compared to 74.6% 1 year after discharge. Especially patients with a CHD improved their knowledge on their disease (Figure 1). Education and number of rehabilitations in the past had an influence on the knowledge of interviewed patients on the day of admittance. Especially elderly patients had an increase in knowledge, indicated by a higher score in the questionnaire (Table 3). Participation in patients' self-help meetings within the observation time had no influence on the knowledge. Patients with known hypertension or hyperlipoproteinemia and overweight patients could increase knowledge on the cardiovascular risk of their disease (Figure 2). CONCLUSION: The results of this query document the lack of knowledge on cardiovascular risk factors of patients before rehabilitation. Especially the results of patients with a diagnosed (and treated) CHD after an inpatient stay in an acute hospital in the past were surprising. The stationary rehabilitation is an appropriate measure to improve this knowledge. It can be used for secondary prevention. The raise in knowledge was evident 1 year after discharge; a long-term effect of health education during stationary rehabilitation is likely.
