| Abstract

This dissertation investigates how healthcare provider networks are formed and their effects on patient health outcomes. The first chapter explores three types of hospital networks that are intended to improve coordination of patient care across different hospitals: integrated delivery systems, accountable care organizations, and electronic health records. Using 2007–2017 Healthcare Information and Management Systems Society IT data and Medicare data on accountable care organizations and hospital quality, I document several interesting patterns regarding the formation and potential effects of these networks in the United States. I find correlations consistent with assortative matching where higher quality hospitals match with higher quality groups, which may be inefficient if there are peer effects that mean higher quality groups could have more substantial influence on lower quality hospitals that have more room to improve. I show that accountable care organizations appear to be strategic about the network formation process, omitting hospitals that are natural members. They may do so for anticompetitive reasons–ordinary least square regressions find that accountable care organization market concentration is negatively correlated with hospital quality. These regressions additionally point to the need for caution in advocating for a unified electronic health record, as hospital quality is positively correlated with regional electronic health record market concentration–which is related to coordination abilities–but negatively correlated with national concentration–which is related to competition.
