Improving Pneumococcal Vaccination in Pediatric Rheumatology Patients

Many pediatric rheumatology patients are at increased risk of pneumococcal disease secondary to a deficient immune system and/or immunosuppressive medications. The goal of this study was to improve pneumococcal vaccination rates in this high-risk population.

Eligible patients included children at least 2 years old and adults with systemic lupus erythematosus and/or currently on immunosuppressive medication. Interventions included a presentation to rheumatology providers,creation of immunization algorithm, previsit planning, placing reminders on clinic forms, and sending reminder e-mails to providers. Chart reviews were performed, and control charts were established to portray change in immunization rates.

The preintervention immunization rates for 90 patient visits compared with the immunization rates for the 53-week postintervention period with 1033 patient visits and 299 separate patients were all statistically significant.The 13-valent pneumococcal conjugate vaccine rate increased from 6.7% to48.4% (x2 = 58.3, P , .001), 23-valent pneumococcal polysaccharide vaccinerate increased from 8.9% to 28.4% (x2 = 16.0, P , .001), and combined rate increased from 0% to 23.2% (x2 = 25.2, P , .001). The improvement was sustained with shifts in the data for each vaccine and combined immunizations for final average rates of 60.9% for 13-valent pneumococcal conjugate vaccine, 39.2% for 23-valent pneumococcal polysaccharide vaccine,and 33.7% for combined.

Pneumococcal vaccination is an important part of the care for systemic lupus erythematosus patients and patients on immunosuppressive medications. Simple interventions through this quality improvement project led to a marked increase in pneumococcal vaccination rates in this vulnerable population.
