Role of out of hours primary care service in limiting inappropriate access to emergency department.

Out of hours (OOH) doctors can have an important gate-keeping role over the access to the emergency department (ED), but the outcome and the quality of their ED referrals have been poorly studied. We aimed to investigate the outcome of patients referred to ED from OOH service and the determinants of admission or short-stay dispositions. We collected retrospectively data about referrals to ED from a local OOH service in the north-east of Italy using the OOH paper register and the ED electronic database, over the period of 01/10/2012 to 31/03/2013. Out of 5217 patients accessing the OOH service, 408 referrals were included in our analysis. 45.3% (185) of the referrals were admitted to hospital or the short-stay unit, 26 patients (=6.4%) were discharged as non-urgent outgoing codes after no specialist consultation or test, suggesting inappropriate referrals, and, of the remaining 197 (=48%), only 10 did not undergo any investigation or consultation. Significant determinants of admission were: age ≥65 years (OR = 2.619; 95% CI 1.528-4.491, p < 0.0001), domiciliary examination (OR = 2.168; 95% CI 1.353-3.476, p = 0.001), nursing home/palliative care setting (OR = 2.563; 95% CI 1.228-5.351, p = 0.012) and OOH triage code, ranging from an OR of 7.47 (95% CI 3.028-18.433) for minor urgencies to an OR of 26.835 (95% CI 6.761-106.508, p < 0.0001) for emergencies, in comparison to no urgent codes. OOH service seems to play an effective gate-keeping role limiting ED access. Determinants of admission to hospital suggest some simple interventions that could improve the adequacy of ED referral from OOH service.

Predictors of emergency department referral in patients using out-of-hours primary care services.

BACKGROUND: Out of hours (OOH) doctors could manage many cases limiting the inappropriate accesses to ED. However the possible determinants of referral to ED by OOH doctors are poorly studied. We aimed to characterize patients referred from the OOH to ED service in order to explore the gate-keeping role of OOH service for hospital emergency care and to facilitate future research in improving its cost-effectiveness. METHODS: A retrospective study was made through data collection of 5217 contacts in a local OOH service in the North-East of Italy (from 10/01/2012 to 03/31/2013). RESULTS: Only 8.7% (=454 people) of the total contacts were referred to ED. In the multivariate analysis, the significant predictors of being sent to ED were: age; residence in nursing home (odds ratios (OR)=2.00, 95%CI: 1.30-3.10); being visited by a OOH physician (OR=2.64, 95%CI: 2.09-3.34). Taking infections as reference, cardiovascular diseases (OR=18.31, 95%CI: 12.01-27.90), traumas (OR=8.75, 95%CI: 5.36-14.26) and gastrointestinal conditions (OR=7.69, 95%CI: 4.70-11.91) increased the probability to be referred to ED. CONCLUSIONS: OOH service addresses several common medical conditions in community-dwelling and in nursing home context, supporting its filtering function for the ED access. The main reasons of ED access could be a crucial aspect in general population education in order to avoid the overcrowding of the ED.
