EGS P13 Adherence to Guidelines for Post-Splenectomy Patients in a Primary Care Practice in North West England

Abstract

Abstract Background Splenectomy is indicated in haematological, oncological disorders and occasionally during emergency (trauma) surgery. Given the spleens role in the immunological response, overwhelming infection remains an area of concern for post-splenectomy patients with low prevalence (0.1-0.5%) but high mortality (∼50%). Strep pneumoniae, H influenzae Type B and Neisseria meningitidis are common bacterial perpetrators. At present, Public Health England and the British Society for Haematology recommends regular influenza, pneumococcal and meningococcal vaccinations for patients with asplenia or hyposplenism. They should also be on lifelong prophylactic antibiotics. This audit aimed to assess the adherence to vaccination and antibiotic prophylaxis guidelines for post-splenectomy patients. Methods 19 patients post splenectomy patients were identified at a primary care practice in North West England. Data was retrospectively collected from the last 10 years with two researchers manually searching through their GP records. Parameters collected included both compliance and timeliness with vaccinations and antibiotic prophylaxis as per national guidance. Where there was a deviation from the guidance, the records were again searched to identify any cause. Results 109/162 (67.3%) ‘vaccination opportunities’ for the recommended yearly influenza vaccination were successfully delivered. 17/19 (89.4%) patients had no documented initial pneumococcal vaccination at time of splenectomy. 23/162 (14.2%) influenza and 22/37 (56.4%) pneumococcal vaccination opportunities were missed with no documentation explaining why. Only 1 patient received the recommended MenACWY/MenB vaccination at diagnosis, 5 received delayed vaccinations and 13/19 (68.4%) patients received no meningitis vaccination. 7/19 (37%) patients were not on prophylactic antibiotics as recommended with no documented explanation. 2 of those patients were issued one-off antibiotic prescriptions and 1 had their prescription stopped due to non-compliance. Conclusions Significant improvement is needed with regards to antibiotic prophylaxis, pneumococcal and meningococcal vaccinations with over 50% of vaccinations being missed. Poor documentation and a shift to electronic health records are possible factors that have affected data collection, particularly as a significant number of the splenectomies performed were prior to 2000. Recommendations include routine reviews for asplenic patients, encouragement for opportunistic vaccination and increasing awareness of the risks of post-splenectomy sepsis and the benefits of vaccinations. Future scope could include looking at the same guidelines for other hyposplenic/asplenic conditions.
