Paper abstract bibtex Background & Hypothesis: The association between influenza epidemics and increased hospital utilisation is well documented. To help inform whether opportunistic vaccination at hospital specialist outpatient clinics (SOC) could be beneficial, we analysed hospital admissions data in relation to prior outpatient clinic visits. Method(s): We extracted all emergency admission episodes from 1 January 2010 to 31 August 2012, to Tan Tock Seng Hospital (TTSH). We then populated the database with TTSH outpatient clinic appointments from 1 January 2009 to 31 August 2012. We also included the most recent outpatient clinic specialty the patient attended before their admission episode. Result(s): From 1 January 2010 to 31 August 2012, there were 136,338 emergency admissions from 84,404 individuals to TTSH. Of these, 33,463 (43.2%) were in the recommended risk group to receive influenza vaccine on the basis of being \textgreater65 years old. We found that 73.7% and 86.0% of them had a prior outpatient clinic appointment \textless6 months and \textless12 months respectively before a hospital admission episode. The top 3 medical specialties the patients visited prior to their hospital admissions were ophthalmology (13.4%), cardiology (10.9%) and geriatric medicine (7.4%). Discussion & Conclusion(s): We have found that a large proportion of emergency hospital admissions had a prior outpatient clinic visit 6 to 12 months prior. The proportions reported here were only based on age criteria recommendations for vaccination and were likely an underestimate. SOC may provide an ideal opportunity for targeted vaccination e.g. influenza or pneumococcal vaccines as a cost-effective strategy to relieve bed pressures in acute hospitals.
