RESUMO
Streptococcus pneumoniae is a significant bacterial pathogen, especially in the elderly. There are two types of pneumococcal vaccines, one with polysaccharides from the capsule of 23 serotypes (PPSV23) and one with polysaccharides from 13 serotypes that have been conjugated to a protein (PCV13). Both vaccines decrease the incidence of invasive pneumococcal disease and are recommended for all people ≥65 years of age. We found the vaccination rate against S. pneumoniae in patients ≥65 years of age in our resident physician continuity clinics was 59.85%, which is considerably lower than the vaccination rate of 69.16% in our attending physician clinics. The aim of our study was to double the number of vaccinations given in the resident physician clinics over a 1-month period without compromising workflow or unduly burdening the rooming nurse or resident physicians. For our primary intervention, we assigned a designated nurse with expertise in vaccinations the task of reviewing charts ahead of clinic visits then pending the order for the appropriate pneumococcal vaccine. Our secondary intervention was the education of physicians through pocket cards, verbal encouragement and email reminders. χ² test was conducted to compare the proportion of patients 65 years or older who were vaccinated between the intervention and control groups. The results indicated that the intervention group patients were 2.61 times (95% CI 1.18 to 6.10) more likely to be vaccinated compared with the control group patients (20% vs 8.7%, χ2 (1)=5.16, p=0.02, Cramer's V=0.16). The intervention resulted in more than doubling the number of vaccinations in the intervention group compared with the control group. Moreover, poststudy interviews and surveys indicated our workflow is sustainable and amendable to wider use within the resident physician clinics.
