Background: Patients with immune-mediated conditions such as IBD and RA are at risk for vaccine-preventable infections. Despite guideline recommendations, prior studies have shown suboptimal vaccination rates. Aim: We conducted a systematic review and meta-analysis to compare the different interventions intended to increase vaccination rates. Methods: A systematic search was conducted of MEDLINE/PubMed, Embase, CINAHL, and Cochrane Library up to 2020 for studies with interventions intended to increase vaccination rates. We performed a random-effects meta-analysis to generate pooled odds ratios (ORs) to assess all interventions against no interventions. Our primary outcome was pneumococcal vaccination (PCV) rate. Results: Our review found 8580 articles, for which 15 IBD and 8 RA articles met the inclusion criteria; 21 articles were included in the analysis. PCV was the predominant vaccination (91%). In our analysis of patients with IBD, almost all interventions (patient-oriented, physician-oriented, or barrier-oriented) increased PCV uptake [OR, 4.74; 95% CI, 2.44–6.56, I2 = 90%] compared to no intervention. The greatest effect was seen in barrier-oriented studies [OR, 12.68; 95% CI, 2.21–72.62, I2 = 92%]. For RA data, all interventions had increased PCV uptake compared to no interventions (OR 2.74; 95% CI, 1.80–4.17, I2 = 95%). Conclusion: Our data suggest that many different interventions can increase PCV rates. It appears that barrier-oriented interventions may have the greatest positive effect on increasing PCV uptake. However, clinicians should be encouraged to implement measures best suited to their practice. Future high-quality randomized controlled trials are needed to determine the best approach to optimize vaccination rates. Graphical Abstract: [Figure not available: see fulltext.].
