A new study on Patient Centered Medical Homes has been published in Health Affairs and we have a new, but predictable, indictment against small independent primary care practice. The study authored by Rittenhouse, Casalino, Shortell et all, is descriptively titled“Small And Medium-Size Physician Practices Use Few Patient-Centered Medical Home Processes”, and follows an earlier 2008 studythat surveyed large medical groups. The study is surveying practices with 1 to 19 physicians, and in a nutshell, small practices, particularly those owned by physicians, are less likely to have medical home processes incorporated in their workflows. On average, the bigger the practice, the more likely it is that medical home processes are used, and the likelihood increases if the practice is owned by a hospital or an HMO. Hardly surprising, but the enlightenment is, as usual, in the details.
The patient centered medical home model is based on the seven joint principles stated by the various primary care associations as follows: personal physician, whole person orientation, physician led care team, coordinated care, quality and safety focus, increased access and payment reform. Both studies quoted above were restricted to measurement of processes indicative of only four out of the seven principles. Personal physician for each patient and whole person orientation were left out, and so was the payment reform principle, although some measures of external incentives in support of medical home processes were considered.
The existence of physician led care teams was ascertained based on the existence of “a group of physicians and other staff who meet with each other regularly to discuss the care of a defined group of patients and who share responsibility for their care”. Not sure why, but solo and 2 doc practices were not even asked this particular question.
