BACKGROUND: In June, 2012 a single dose of 13-valent pneumococcal conjugate vaccine (PCV13) was added to the recommendation for immunocompromised adults who were previously recommended to receive only 23-valent pneumococcal polysaccharide vaccine (PPSV23). PCV13 may be more effective, though it covers fewer disease-causing strains. OBJECTIVE: We examined the incremental cost-effectiveness of adding one dose of PCV13 to the pre-2012 recommendation of PPSV23 for adults with 4 immunocompromising conditions who are at increased risk of pneumococcal disease: HIV/AIDS, hematologic cancer, solid organ transplants, and end stage renal disease. METHODS: We used a probabilistic model following a single cohort of 302,397 immunocompromised adults. We used vaccination coverage and disease incidence data specific to each immunocompromising condition. Assumptions about PPSV23 and PCV13 vaccine effectiveness were based on two randomized controlled trials and several observational studies conducted among HIV-infected adults. Because no such studies have been conducted among other immunocompromised populations, we made further assumptions about the relative vaccine effectiveness in those groups. Cost-effectiveness ratios were determined for each condition and for all 4 groups in total. RESULTS: Our model indicated that adding one dose of PCV13 to adults in the United States with 4 immunocompromising conditions would cost $16 million (in 2009$) but provide off-setting savings of $21 million per cohort from the societal perspective. These savings come largely from decreased medical costs among adults with end stage renal disease. This dose of PCV13 would prevent 57 cases of invasive pneumococcal disease, 619 cases of hospitalized all-cause pneumonia, avert 93 deaths, and save 1360 quality adjusted life years per cohort. CONCLUSION: The addition of one dose of PCV13 to the previously recommended PPSV23 doses for adults with selected immunocompromised conditions potentially reduces both disease and costs.
