The IMPACT Survey: The Economic Impact of Caring for an Individual with Osteogenesis Imperfecta.

INTRODUCTION

The IMPACT Survey ("IMPACT") investigated the economic, clinical, and humanistic challenges of osteogenesis imperfecta (OI) on affected individuals, caregivers, and the broader community. Prior publications detail the methodology, initial findings, healthcare expenditures, and quality of life (QoL) impact on adults with OI. Here, data is presented on the productivity and finances of caregivers and any predictors of impact. We hypothesise that caring for an individual with OI will impact the productivity and finances of caregivers.

METHODS

IMPACT, fielded July through September 2021 in eight languages, targeted adults and adolescents with OI, caregivers (with or without OI), and close relatives. Survey items covered demographics, socioeconomic factors, clinical characteristics, treatment patterns, QoL, and health economics. We performed descriptive analyses of caregivers' productivity and finances and exploratory regression analyses to identify independent associations between care recipient and caregiver characteristics ("predictors"), and their economic impact on caregivers.

RESULTS

Of 528 caregivers (without OI) with one care recipient, 64% were in paid employment. Of these, 50% reported missing workdays in the preceding 4 weeks (mean 1.9 days). Caregivers reported impacted finances, spending a mean total of €209 out of pocket (OOP) with the most spent on travel to medical appointments (mean €83) and medicine (mean €46) in the preceding 4 weeks. Caregiver spending varied across regions. Caregivers in the USA spent more in 4 weeks (mean €334) than caregivers in EU4 (France, Germany, Italy, and Spain) and UK (mean €163) or Nordic countries (mean €33). Predictors of productivity and OOP spending included caregiver age, sex and employment status, care recipient age, and various signs, symptoms, and events.

CONCLUSION

Our results suggest that caring for an individual with OI may impact caregivers' productivity and finances. The degree of impact may be predicted by caregiver and care recipient age, fracture frequency, and dental problems.
