N2  - BACKGROUND: The effect of Level IV trauma center (TC) accreditation within an existing trauma network remains understudied. This study compared pre- to post-accreditation data from Level IV TCs within a mature trauma system in Pennsylvania to determine whether TC designation affected time to and/or rate of transfer to definitive care. Level IV TCs were hypothesized to have a decreased time to transfer following accreditation and improved mortality. <br><br>METHODS: The Pennsylvania Trauma Systems Foundation (PTSF) collects pre- and post-designation data from hospitals pursuing accreditation. Data from PTSF between 2012 and 2017 was analyzed. Variables of interest included patient demographics, injury severity, mortality and incidence of surgical interventions pre- to post-credentialing. A multilevel mixed-effects logistic regression model assessed the adjusted impact of Level IV TC accreditation on transfer rate. ArcGIS Desktop was used for geospatial mapping of lives and geographic area covered by the addition of Level IV TCs in Pennsylvania RESULTS: Five hospitals underwent Level IV credentialing from 2012-2017, providing data on 5,076 cases (Pre: 2,395 [47.2%]; Post: 2,681 [52.8%]). No significant difference in age, admission Glasgow Coma Scale score, or shock index was observed pre to post-accreditation. A difference in transfer rate was observed after credentialing in unadjusted (62.7% vs. 63.3%; p<0.014) and adjusted analyses (AOR: 1.13, p=0.389). There was a trend toward reduced odds of mortality post-credentialing (AOR: 0.59, p=0.261). Major surgical intervention decreased (Pre: 0.42%, Post: 0.04%; p=0.004). <br><br>CONCLUSION: Level IV TC accreditation has beneficial effects on increased transfer rates and may improve mortality. It is important to continue to observe the impact of Level IV TCs on patient outcomes within a mature trauma system. LEVEL OF EVIDENCE: III; prognostic and epidemiological.<p />  <p>Language: en</p>
