Objective: To review the literature on pneumococcal vaccination compliance rates among cochlear implant (CI) patients and to examine the utility of intervention programs on increasing vaccination rates. Data Sources: PubMed, Scopus, and CINAHL. Review Methods: A systematic review was performed following PRISMA guidelines. Studies of pneumococcal vaccination rates at baseline and before and after the implementation of a quality improvement (QI) intervention were included. A total of 641 studies were screened, and 13 studies met inclusion criteria. Meta-analyses of pneumococcal vaccination rates pre- and post-QI intervention in CI patients were performed. Results: A total of 12,973 children and adults were included. The baseline PCV13 and PPSV23 vaccination rates were 53.45% (95% CI, 37.02%-69.51%) and 42.53% (95% CI, 31.94%-53.48%), respectively. Comparing children and adults, PCV13 and PPSV23 baseline vaccination rates were not statistically significant. The PPSV23 vaccine rate after QI initiatives was significantly higher than the baseline rate at 83.52% (95% CI, 57.36%-98.46%). After these interventions, patients had a 15.71 (95% CI, 4.32-57.20, P <.001) increased odds of receiving PPSV23 vaccination compared to before QI implementation. Conclusions: The baseline rates of PCV13 and PPSV23 are highly variable and lower than expected, given current vaccination recommendations for CI patients. QI programs appear successful in increasing compliance rates with the PPSV23 vaccination; however, they are still far from full compliance. Further intervention programs with stricter surveillance, monitoring, and follow-up systems are needed to achieve improved compliance with the PCV13 and PPSV23 vaccination in CI recipients.
