Abstract Background Prior research suggests that many patients do not spontaneously include work/income loss when responding to utility assessments, although this remains unconfirmed in the US due to almost no published US-based studies to date, and has not been previously studied among patients with herpes zoster (HZ). The objective of this study was to examine whether patients with HZ consider work and income loss when completing a quality of life survey. Methods A cross-sectional survey was administered to 2000 US adult commercial health plan enrollees aged 50–64 years with ≥ 1 HZ medical claim during 2014. The survey collected information related to health status (EQ-5D), work productivity, and HZ severity and clinical features. Results Mean respondent age was 58.4 years [standard deviation (SD) 4.1] and 62.0% were female. About 3 in 4 (76.8%) patients (N = 772) were employed either full (69.9%) or part time (6.9%). Less than half (45%) spontaneously considered work/income loss when responding to EQ-5D, and mean EQ-5D scores for patients who considered work/income loss were lower than for patients who did not [0.56 (SD = 0.28) vs. 0.69 (SD = 0.24); p < 0.001]. Overall, 43% of patients reported at least one full day missed (mean = 9 full days) and 29% reported at least one partial day missed (mean = 6 partial days) during the most recent shingles episode. Patients who considered work loss were more likely to have missed full (76.4% vs 26.0%, p < 0.001) or partial (70.9% vs. 35.2%, p < 0.001) days. Patients with absenteeism were more likely to consider work/income loss when completing EQ-5D [odds ratio (OR) = 7.91, 95% confidence interval (CI) 5.01–12.31]. Odds of absenteeism/presenteeism increased significantly with increasing levels of HZ severity, and higher odds were associated with pain located on the face/scalp/neck/eye/ear (OR 1.90, 95% CI 1.06–3.40) and with pain lasting 12+ months (OR = 2.91, 95% CI 1.14–7.42). Conclusions HZ has considerable impact on the work and productivity of adults aged 50–64 years old. However, many patients with HZ do not spontaneously consider work/income loss when completing a standardized quality of life questionnaire. Studies that use health state utilities in HZ based on EQ-5D may not fully reflect the societal costs of work loss.
