We report a project that utilized pharmacy students to increase pneumococcal vaccination rates in patients aged 19-64 years with high-risk medical conditions within urgent care clinics. The study also sought to better identify the number of patients previously vaccinated for pneumococcal disease. A total of 1,178 patients were considered eligible for pneumococcal vaccination during the study period, 287 (24.4%) of whom were determined to be previously vaccinated through chart assessment or patient interview. Of the remaining 891 patients, chart documentation of pneumococcal vaccination administered at the time of the urgent care visit was present for 96 patients (10.7%) in the intervention clinics compared with 6 patients in 2 control clinics who received the usual standard of care (P < .0001).
