Patients and Method: In a pilot study 70 patients treated in the Depar
tment of Cardiology were asked to assess the costs of coronary angiogr
aphy, PTCA, heart transplantation, pacemakers and prosthetic heart val
ves. Salaries of physicians and nurses should be estimated, and causes
of increase of costs in health carl be defined. Results: 91.7% patien
ts criticized health care as too expensive but reasonable with regard
to output and efficacy. As most important reasons for increase of cost
s were given: ''expensive drugs'' (70.6%,), ''great number of drugs''
(56.9%) and ''increased number of old patients'' (56.9%). Costs of cor
onary angiography were overestimated (twice) and those of PTCA were un
derestimated (half). Two thirds of the patients guessed the prices of
pacemakers and prosthetic heart valves much to low. Salaries of physic
ians had been estimated near the upper reference value, those of nurse
s near the lower reference value. Conclusion: Most of our patients wer
e insufficiently informed about costs in health care. Clarification an
d more transparency are needed.
