This paper considers the subject of managed care in Malaysia, providing a questionnaire-based analysis of the position adopted by private medical practitioners. Managed care is now seen as the dominant health care system in the United States, with many other countries around the world including Malaysia beginning to selectively use component parts to tackle particular health care problems. In this survey it was found that three out of four respondents have concerns regarding the implementation of managed care. The survey was used to identify and categorise these concerns. At the same time, three out of four respondents held the opinion that principles of managed care were already a reality or would be in the next 5 years. This group expressed an eagerness to be trained in managed care principles and be given the opportunity to be part of managed care organisations. It is argued that clinicians' knowledge and interest perceptions are an important influence on the implementation of managed care based systems. The survey-based evidence presented in this article is intended as a measure of current understandings and beliefs, in relation to clinical micro-management process associated with managed care.
