Influenza vaccination is now recommended for all ages; CDC pneumococcal polysaccharide vaccination (PPV) recommendations are comorbidity-based in nonelderly patients. We constructed a Markov model to estimate the cost-effectiveness of dual influenza and pneumococcal vaccination in 50-year-olds. Patients were followed for 10 years, with differing time horizons examined in sensitivity analyses. With 100% vaccine uptake, dual vaccination cost $37,700/QALY gained compared to a CDC recommendation strategy; with observed vaccine uptake, dual vaccination cost $5,300/QALY. Results were sensitive to shorter time horizons, favoring CDC recommendations. We found dual vaccination of all 50-year-olds economically reasonable. Shorter duration models may not fully account for PPV effectiveness.
流感疫苗接种现推荐用于所有年龄段;美国疾病预防控制中心(CDC)的肺炎球菌多糖疫苗(PPV)接种建议是基于非老年患者的合并症制定的。我们构建了一个马尔可夫模型,以评估对 50 岁人群同时进行流感和肺炎球菌疫苗接种的成本效益。患者随访 10 年,敏感性分析中还考察了不同的时间范围。在 100%疫苗接种率的情况下,与 CDC 推荐方案相比,双重疫苗接种的成本为每 QALY 增加 37700 美元;在观察到的疫苗接种率下,双重疫苗接种的成本为每 QALY 增加 5300 美元。结果对较短的时间范围较为敏感,更倾向于 CDC 的推荐方案。我们发现对所有 50 岁人群进行双重疫苗接种在经济上是合理的。持续时间较短的模型可能无法充分体现 PPV 的效果。
