Methods: Comprehensive medical record review from the population of patients treated in a level 1 trauma center ED from 01/01/2012 to 03/31/2013 (N=49,354) was conducted. Content analysis of chart notes was used to categorize SWS. Poisson regression assessed associations between demographic and clinical characteristics, SWS and length of ED stay.
Results: SWS were provided to N=18,532 (38%) patients. The majority were mental health services (54%), followed by care coordination (31%) and material support/other referrals (15%). Patients seen by social work were complex, presenting with mental health (18%), substance abuse (29%) or comorbid diagnosis (32%), injury (51%), and had multiple ED visits (26%). In adjusted regression analysis females (RR=1.15, CI=1.13-1.17), non-home discharge disposition (RR=1.44, CI=1.41-1.48), comorbid diagnoses (RR=1.80, CI=1.71-1.89), assault (RR=1.37, CI=1.31-1.44), and TBI (RR=1.20, CI=1.17-1.22) were associated with an increased likelihood of SWS. SWS were associated with an increased length of stay (RR=1.34, CI=1.27-1.41).
Conclusions and Implications: Social workers provided services to patients with multifaceted needs resulting from complex mental health, substance abuse, trauma and comorbid presentations. SWS resulted in a modest increased length of stay. There is a need for triage algorithms to target efficiencies, systematize ED SWS and improve access to needed services for all patients. Methods to expand ED SWS could be a productive area for future research, particularly if social work services prove effective in reducing ED recidivism.
