PURPOSE Patient ratings of physician's patient-centered communication are used by various specialty credentialing organizations and managed care organizations as a measure of physician communication skills. We wanted to compare ratings by real patients with ratings by standardized patients of physician communication.
METHODSWe assessed physician communication using a modifi ed version of the Health Care Climate Questionnaire (HCCQ) among a sample of 100 community physicians. The HCCQ measures physician autonomy support, a key dimension in patient-centered communication. For each physician, the questionnaire was completed by roughly 49 real patients and 2 unannounced standardized patients. Standardized patients portrayed 2 roles: gastroesophageal disorder refl ux symptoms and poorly characterized chest pain with multiple unexplained symptoms. We compared the distribution, reliability, and physician rank derived from using real and standardized patients after adjusting for patient, physician, and standardized patient effects.RESULTS There were real and standardized patient ratings for 96 of the 100 physicians. Compared with standardized patient scores, real-patient-derived HCCQ scores were higher (mean 22.0 vs 17.2), standard deviations were lower (3.1 vs 4.9), and ranges were similar (both 5-25). Calculated real patient reliability, given 49 ratings per physician, was 0.78 (95% confi dence interval [CI], 0.71-0.84) compared with the standardized patient reliability of 0.57 (95% CI, 0.39-0.73), given 2 ratings per physician. Spearman rank correlation between mean real patient and standardized patient scores was positive but small to moderate in magnitude, 0.28.
CONCLUSION
INTRODUCTIONP atient-centered care is a core dimension of health care quality, and strong communication skills are required to ensure such care.1 Yet, policy makers and researchers do not know how best to measure these physician communication skills.2 Because patient ratings of physician communication from surveys have face validity and are readily available, they are widely used by such organizations as the American Board of Internal Medicine and various managed care organizations.3 These ratings may eventually be used for specialty recredentialing and to determine physician bonus payments.Patient ratings of physicians are subject to a number of limitations, however. These limitations include potential biases from survey nonresponse, patient selection (and deselection) of the physician, patient accommodation to the physician's style with time, 4 length of relationship, different patient complaints, and ceiling effects. 5 Patients also respond in a global manner when rating their physicians, with high correlations among scales measuring Kevin Fiscella, MD Standardized patients-persons trained to portray a specifi c patient case in a standardized fashion 8 -represent a potentially more objective means for assessment of physician communication.
