Medicare Patient Referral Networks to Pelvic Floor Physical Therapy Across the United States

Objective The purpose of this study is to evaluate the distribution of referrals to pelvic floor physical therapy throughout the United States and to identify specialties with the highest and lowest referral rates. Referral networks to pelvic floor physical therapy were identified, and factors associated with referral connections were determined. Methods This retrospective network analysis of referrals examined U.S. Centers for Medicare and Medicaid Services data from 2009 to 2017. Pelvic floor physical therapists were identified, and their patient-sharing networks were modeled using social network analytics. Results There were 18,740 Medicare beneficiaries referred to pelvic floor physical therapists between 2009 and 2017. The mean number of referrals to each physical therapy provider or practice was 82 (SD ±46.3). Half of the referrals were made by a general acute care hospital. The remainder were referred by female pelvic medicine and reconstructive surgeons, nurse practitioners, colorectal surgeons, internal medicine, and obstetrician-gynecologists. The number of individual pelvic floor physical therapists, as well as the referrals, increased each year. The geographic representation of the patient referral networks is illustrated. The map reveals that pelvic floor physical therapists often work in groups and treat patients in their geographic vicinity. In this study, we demonstrate intensely fractured referral networks. Conclusion Our network analysis of pelvic floor physical therapy referrals in Medicare patients across the United States shows fractured networks with dense geographic connections in some areas, whereas sparse in others. Multidisciplinary approaches and early referrals to pelvic floor physical therapy are recommended as some ways to amend these fractured networks.
