A recent study published in JAMA – “Delivery of Preventive Services to Older Americans by Primary Care Providers” – concluded that the delivery of these services was ‘suboptimal’ for Medicare beneficiaries and that in certain practice settings and with certain provider subgroups these patients were “at particular risk of low-quality care.”  While the presence of electronic reminder systems, Board certification, training in the US or Canada and larger practice size (> 3 physicians) generally predicted statistically better care, of note to those who deliver care to underserved populations (and this study included Bureau of Primary Health Care sites), one of the strongest predictors of suboptimal care was whether the percentage of a practice’s revenues from Medicaid was grater than 15%.  Why this may have been a factor was not discussed, but this finding by the study invites Community and Migrant Health Centers to study their effectiveness at delivering such services to determine whether C/MHCs are or are not like those sites noted here with large Medicaid populations who were found to provide suboptimal care.
