Study finds performance trends tied to Joint Commission accreditation

Accreditation Connection, October 14, 2011

A recent study published in the Journal of Hospital Medicine found that hospitals accredited by The Joint Commission, examined in the study, tended to have better baseline performance in 2004 than non-accredited hospitals. Accredited hospitals had larger gains over time, and were significantly more likely to have high performance in 2008 on 13 out of 16 standardized clinical performance measures and all summary scores.

The study used performance data, obtained using publicly available CMS Hospital Compare data, for 2004 and 2008 from U.S. acute care and critical access hospitals, augmented with Joint Commission performance data.

The study reported that while, in the early days of public reporting, Joint Commission-accredited hospitals already outperformed non-accredited hospitals on publicly reported quality measures, these differences became significantly more pronounced over five years of observation.
