(HealthDay)—Online consumer ratings of specialist physicians do not predict objective measures of quality of care or peer assessment of clinical performance, according to a study published online Sept. 8 in the Journal of the American Medical Informatics Association.

Timothy J. Daskivich, M.D., M.S.H.P.M., from Cedars-Sinai Medical Center in Los Angeles, and colleagues compared consumer ratings with specialty-specific performance scores (metrics including adherence to Choosing Wisely measures, 30-day readmissions, length of stay, and adjusted cost of care), primary care physician peer-review scores, and administrator peer-review scores for 78 physicians representing eight medical and surgical specialties.

The researchers found that across ratings platforms, there was no significant association between mean consumer ratings and specialty-specific performance scores, scores, or administrator scores. There was also no association between ratings and score subdomains related to quality or value-based care. For physicians in the lowest quartile of specialty-specific performance scores, only 5 percent to 32 percent had consumer ratings in the lowest quartile across platforms. Ratings were consistent across platforms, with a 's score on one platform significantly predicting his/her on another in five of 10 comparisons.

"Online consumer ratings should not be used in isolation to select physicians, given their poor association with clinical performance," conclude the authors.
