Introduction

This study aimed to describe pneumococcal polysaccharide vaccine-23 (PPSV23) vaccination use in high-risk pediatric patients with chronic heart disease (CHD).

Method

This was a single-center retrospective cohort study. Patients were included if they were aged 2–18 years and were diagnosed with CHD. The primary outcome was PPSV23 vaccination. Secondary outcomes included missed opportunities and the incidence of infections.

Results

Three hundred ninety-two patients were included; the mean age was 8.8 years. Only 40 patients (10.2%) had documentation of PPSV23 vaccination. Patients had a median number of three clinic visits in 2019. There were 114 cases of pneumonia documented in patients before receiving PPSV23 and one case reported after PPSV23 vaccination.

Discussion

PPSV23 vaccination in high-risk pediatric patients with CHD was low, with many documented missed opportunities for vaccination. This may be attributed to the PPSV23 not being a routine vaccination on the pediatric schedule.

慢性心脏病儿科患者肺炎球菌纯多糖疫苗接种

介绍

本研究旨在描述肺炎球菌多糖疫苗 23 (PPSV23) 疫苗接种在患有慢性心脏病 (CHD) 的高危儿科患者中的使用情况。

方法

这是一项单中心回顾性队列研究。如果患者年龄为 2-18 岁并被诊断患有 CHD，则纳入其中。主要结果是 PPSV23 疫苗接种。次要结果包括错失机会和感染发生率。

结果

其中包括三百九十二名患者；平均年龄为8.8岁。只有 40 名患者 (10.2%) 有 PPSV23 疫苗接种记录。2019 年，患者平均就诊 3 次。在接受 PPSV23 之前，患者记录了 114 例肺炎病例，在接种 PPSV23 疫苗后报告了 1 例肺炎病例。

讨论

高危先天性心脏病儿科患者的 PPSV23 疫苗接种率较低，许多记录显示他们错过了疫苗接种机会。这可能是由于 PPSV23 不是儿科疫苗接种计划中的常规疫苗。
