Background 

Survey studies have shown that physicians believe managed care is having significant impact on many of their professional obligations.

Methods 

Primary care physicians were asked about the impact of managed care on : (1) physician-patient relationships, (2) the ability of physicians to carry out their professional ethical obligations, and (3) quality of patient care.

In 1996 we surveyed 1011 primary care physicians in Pennsylvania.

The survey group's responses were graded on a Likert scale.

Space was provided for respondents to include written comments.

The SPSS statistical software (SPSS Inc, Chicago, Ill) was used to analyze the data.

Results 

The response rate was 55%. Most respondents indicated that under managed care physicians are less able to avoid conflicts of interest and less able to place the best interests of patients first.

The majority responded that quality of health care is compromised by limitations in location of diagnostic tests, length of hospital stay, and choice of specialists.

A significant minority (27% - 49%) noted a decrease in the physician's ability to carry out ethical obligations, to respect patient autonomy, and to respect confidentiality in physician-patient communication.

Most physicians expressed that managed care made no impact on ability to obtain informed consent or to provide information.

There were small but statistically significant sex differences, with female physicians more negative toward managed care. (...)
