Abstract

Background
Herpes zoster (HZ) is characterized by a painful dermatomal rash and is associated with increased healthcare costs. Research quantifying work productivity loss and activity impairment associated with HZ is limited and outdated. This study aimed to describe severity of HZ related pain, health related quality of life, activity impairment, and work productivity among employed adults diagnosed with HZ in the Department of Veterans Affairs (VA) Health System.

Methods
This cross-sectional study utilized a self-reported survey among adults in the VA health system. Eligibility was assessed biweekly from electronic health record data, and adults with an incident International Classification of Diseases, 10th Revision (ICD-10) HZ diagnosis were invited to complete an online survey. Respondents were indexed on their HZ diagnosis and included if aged 18-70 years, reported working for pay at index, and had 6 months of baseline continuous enrollment. Respondents were excluded if they had a baseline HZ vaccine, did not complete the survey within 30 days after index, or reported not having HZ or experiencing a rash &gt; 14 days prior to index. Questions used to assess outcomes were based on validated survey instruments (Table 1). Work productivity was described among respondents employed at survey completion. Data were collected from 05/04/2021 to 07/07/2022. Descriptive statistics were used to summarize survey responses.

Results
Among 231 respondents completing the survey, mean (standard deviation [SD]) age was 49 (10) years and 79% were male. Overall, 70% reported experiencing pain in the last 7 days. Mean (SD) [minimum, maximum] “average-pain” severity and EQ-5D-3L scores were 4.0 (2.8) [0, 10] and 0.69 (0.22) [-0.04, 1.00], respectively. Mean (SD) activity impairment was 42% (33%). Mean (SD) absenteeism, presenteeism, and overall work impairment were 17% (27%), 35% (30%), and 43% (35%) out of 202, 192, and 202 respondents, respectively.

Conclusion
Burden associated with HZ is substantial, with a significant proportion experiencing pain, activity impairment, and work productivity loss. These results provide updated context on the impact of HZ in this population of employed adults in the VA health system.
