Spinal Cord Injury (SCI) Use a disproportionate amount of health services and dollars 1 More likely to have problems accessing health services 1 High risk for: – deteriorating health – onset of secondary conditions – loss of functional independence 1 Live longer, face new challenges associated with longevity 1 Average LOS in post-acute rehab declined from 115 days in 1973 to 36 days in Special Interest Group on SCI Model System Innovation; 2

Previous Research Rates of rehospitalization range 19-57% in the first year post-SCI 1 – Largely due to secondary conditions (e.g., pneumonia, pressure sores, UTIs) Lower Motor FIMs at rehab discharge associated with increased readmissions 3 However, this research is limited to: – Single institutions – Model Systems – International data 3 Brannon R, DeJong G, Batavia A, Meehan, M.

Objectives To identify: – Incidence – Prevalence – Characteristics (e.g., reasons, cost) of healthcare utilization among patients originally admitted to a Level I trauma center with SCI over the course of a decade using a regional hospital registry. #aapmr2015

Setting Level I Trauma Center in Dallas, TX – Admits ~2,500 patients annually Dallas-Ft. Worth Hospital Council – 75 member institutions (>140 hospitals) – 15 years of collected data – 10 million patients – 40 million hospital visits #aapmr2015

Over 15,000 square miles BUMC

Participants #aapmr patients 597 final total 52 excluded Admitted with acute traumatic SCI between Jan 2003-June 2014 Expired during initial hospitalization ≈57 patients/year

Main Outcome Measures Inpatient and outpatient utilization characteristics – Demographics – Insurance – Hospital charges – Diagnosis-related groups (DRGs) – Specialization #aapmr2015

Results #aapmr2015 Demographics N=597 Age 45.9±18.8 Male Gender 443 (74%) Race White 343 (57%) Black 147 (25%) Asian 6 (1%) Other 101 (17%) Hispanic Ethnicity 89 (15%) Insurance Private 245 (41%) Public 122 (20%) Uninsured 230 (39%) =59% Compared to 50.4% in 2014 MS data

N=597 SCI patients 75% (n=447) additional utilization 1850 visits 70% outpatient (1298 visits) 30% inpatient (552) 25% (n=150) none documented Results #aapmr2015 January 2003 – June 2014 Median number of additional visits = 3 Maximum = 22

Results: Inpatient Utilization Post- SCI ≈30% preventable n=

47% were emergency, urgent, or trauma-related LOS – Mean = 10 days – Range = 4-28 days Total charges – Mean = $37,753 – Range = $19,981 - $67,344 #aapmr2015 Results: Inpatient Utilization Post- SCI

Results: Outpatient Utilization Post-SCI n=

21.3% were medical emergency, urgent, or trauma-related Total charges – Mean = $11,487 – Range = $488 - $3,605 #aapmr2015 Results: Outpatient Utilization Post- SCI

Conclusions Individuals with SCI experience healthcare utilization that may be largely preventable Not only costly to the healthcare system but to the individuals with SCI – $ This analysis is unique in that it objectively reports healthcare utilization across different healthcare systems – Not limited to a single institution – Multiple hospitals per patient Increasing understanding of healthcare utilization post acute SCI is critical – Development of preventative strategies – Continuity of care #aapmr2015
