Abstract

Objective: Patients with rheumatoid arthritis (RA) have an increased risk of developing herpes zoster (HZ) compared to the general population. We aimed to measure healthcare utilization (HCU) and related costs of HZ among patients with RA, from the public payer's perspective.

Methods: Adult patients with RA diagnosed with HZ between 2008 and 2020 were matched by sex, age, and date of HZ infection to (1) patients with RA without HZ, (2) the non-RA population with HZ, and (3) the non-RA population without HZ. Unadjusted gamma distribution models and generalized estimating equations were used to compare HCU costs and the number of clinical events (CEs), including hospital admissions and emergency department and physician visits, in patients with RA with HZ to each matched cohort.

Results: We identified 15,573 patients with RA diagnosed with HZ and a similar number for each of the 3 matched cohorts. From year 1 to year 10, mean total cost ranged from CAD $13,507 to CAD $17,120 for the RA with HZ cohort compared to CAD $12,651 to CAD $14,534 in the RA without HZ cohort. Physician billing and inpatient hospital costs were the largest drivers of increased costs for all cohorts. Compared to patients with RA with HZ, each matched cohort experienced a significantly lower mean number of total CEs, with the highest difference in total CEs 1 year following an HZ infection.

Conclusion: HCU and related costs were higher in patients with RA with HZ compared to patients with RA without HZ and non-RA populations with and without HZ. Treatment strategies that minimize the risk of HZ and encourage patients to keep up to date with vaccinations should be considered.

类风湿关节炎患者带状疱疹感染的医疗保健利用和成本:一项回顾性队列研究。
目的:与普通人群相比,类风湿关节炎(RA)患者发生带状疱疹(HZ)的风险增加。我们旨在从公共支付者的角度衡量RA患者的医疗保健利用(HCU)和HZ的相关成本。方法:将2008年至2020年间诊断为HZ的成年RA患者(性别、年龄和HZ日期)匹配为:1)无HZ的RA患者,2)有HZ的非RA人群,3)无HZ的非RA人群。未调整的伽马分布模型和广义估计方程(GEEs)用于比较HCU成本和临床事件(CEs)数量,包括住院、急诊科和医生就诊,RA合并HZ的每个匹配队列。结果:我们确定了15573名被诊断为HZ的RA患者,三个匹配队列中的每一个都有相似的数字。有HZ的RA组的平均总费用从第一年的13,507加元到第10年的17,120加元不等,而没有HZ的RA组的平均总费用为12,651加元到14,534加元。医生账单和住院费用是所有队列中最大的驱动因素。与合并HZ的RA患者相比,每个匹配队列的平均总CEs数明显较低,其中HZ感染后一年的总CEs数差异最大。结论:与没有HZ的RA患者和没有HZ的非RA人群相比,有HZ的RA患者的HCU和相关费用更高。应考虑降低HZ风险和更新患者疫苗接种的治疗策略。
