Association of Patient-Centered Medical Home Designation and Quality Indicators within HRSA-Funded Community Health Center Delivery Sites
Abstract Background: Patient-Centered Medical Home (PCMH) adoption has been proposed as an important strategy to help improve primary care quality within Health Resources and Service Administration (HRSA) Community Health Centers (CHC), but evidence of its effect thus far remains mixed. A limitation of previous evaluations has been the inability to account for the proportion of CHC delivery sites that are designated sites.Methods: Retrospective cross-sectional study using HRSA Uniform Data System (UDS) and certification files from the National Committee for Quality Assurance (NCQA) and the Joint Commission (JC). All datasets were linked through geocoding and approximate string matching. Proportional implementation was assessed in 10% increments and regressed onto 14 clinical performance measures. The analysis included 1,281 community HCs and 8,022 delivery sites within the lower 48 states and District of Columbia.Results: The geocoding and approximate string matching algorithm identified 2,615 of the 6,851 (41.8%) delivery sites included in the analyses as having been designated through the NCQA and/or JC. In total, 74.7% (n=777) of the 1,039 CHCs included in the analysis after removing false positive/negative matches managed at least 1 NCQA and/or JC designated site. There was no stepwise improvement in clinical quality across all 14 indicators as the proportion of designated delivery sites increased. A trend for numerous indicators was that site-level designation rates of at least 90% were associated with better indicator adherence.Conclusion: Geocoding and approximate string matching offers a more accurate approach to monitor the impact of PCMH transformation on meeting quality performance targets. The lack of a consistent stepwise association between increased site-level designation and clinical quality underscores the need for additional risk-adjustment criteria within annual quality performance reporting in order to assess whether PCMH interventions are improving patient care.
