Patient education and recall regarding postsplenectomy immunizations.

BACKGROUND: The purpose of this study was to determine the rates of initial vaccinations after splenectomy for trauma, assess the effectiveness of patient education on reimmunizations, and evaluate patients' utilization of their knowledge regarding immunization after discharge.

METHODS: From June 1996-December 2011, 144 patients underwent splenectomy after traumatic injury. A telephone survey was completed in 100 of 144 splenectomized patients (69%) at a mean of 7.9 y after their splenectomy. Questions were directed to determine the quality of patients' recall of the implications of splenectomy, the need for vaccinations, and the quality of the health information administered. Research electronic data capture tool was used for collecting data, and data were analyzed with Stata 11.2.

RESULTS: Only 27% of participants recall receiving education on postsplenectomy vaccination and 41% of those patients rated their education as poor or minimal. Ninety-one percent of patients indicated that they would like more information in the form of a brochure. Our overall initial vaccination rates among patients who had splenectomy from 1996-2011 were 76%, 75%, and 68% for Streptococcus pneumoniae, Neisseria meningitidis, and Hemophilus influenza type b, respectively. Since 2004, 95% of those who had splenectomy between 2004 and 2007 received all three vaccines. Since 2008, our institution has maintained 100% initial vaccination rates for all three vaccines. The revaccination rates in this group of patients (from 1996-2007) were 39% and 15% for pneumococcal and meningococcal vaccines, respectively.

CONCLUSIONS: Patients had poor recall of the information provided during hospitalization for splenectomy. There were low revaccination rates in our patient cohort. Specific educational and vaccination surveillance strategies are required to improve vaccination rates.
