Pneumococcal vaccination use in Foothills Hospital*. * The number of vaccinations administered in the Foothills Hospital prior to and following the study. The time periods were chosen to correspond with the study periods in 2002 – usual-care period from Feb. 20 to April 16 and the intervention period from April 22 to June 16. The bar graph shows an increase in administration of pneumococcal vaccinations after the intervention and indicating there were significant effects outside of the unit where the intervention occurred and that the effect was sustained after the study was terminated.
