RT Journal A1 Feldman DS T1 PRoactive measures needed for health care reform JF Archives of Internal Medicine JO Archives of Internal Medicine YR 1999 FD June 28 VO 159 IS 12 SP 1370 OP 1371 DO UL http://dx.doi.org/ AB Since the publication of our study, Kao and colleagues4 published a patient survey that indicated that patients' trust in physicians was somewhat less in patients in managed health care programs. At least some of the difference in patients' trust was due to physicians' behavior. Many of the views expressed by the respondents to our survey suggested that practicing in managed care systems could affect physician behavior. Market forces in medicine are changing the practice of medicine. As Dr Erwin indicates, physicians need to monitor and modify these changes through broad societal forums.
