Abstract
PURPOSE: Little is known about the utilization of low vision services (LVS) in Germany. To understand which persons and how often these services would be utilized, this study aimed to investigate low vision aids (LVAs) provision in an urban setting and to describe user characteristics and trends in their characteristics. METHODS: A retrospective study based on a population-based healthcare claims database in Cologne (N = ~ 500,000), Germany. The study population comprised individuals, who were continuously insured at four large statutory health insurers and who redeemed a prescription for visual aids or aids for blindness between January 2014 and December 2017. We examined their socio-demographic and clinical characteristics. Trends in characteristics were examined with logistic and linear regression models over time. RESULTS: Out of ~ 500,000 persons, 781 unique individuals (~ 0.2%) redeemed an LVA prescription. They were mainly female (68.7%), 60 years or older (75.3%) and had macular degeneration (50.6%) and/or glaucoma (25.9%). In the working-age subgroup, 33.8% were employed. Visual aids were most often prescribed (74.1%) and of all types of LVAs, individuals most commonly redeemed a prescription for magnifiers (35.8%), screen readers (34.3%) and/or canes (17.1%). Of the entire study population, 75.4% received their prescription from an ophthalmologist, 5.3% from a general practitioner and 7.1% from other medical specialists. Significant trends in characteristics of individuals who redeemed an LVA prescription were not found. CONCLUSIONS: Between 2014 and 2017, 781 individuals in Cologne redeemed an LVA prescription. They had characteristics which mostly can be explained by the epidemiology of VI. Results indicate that individuals that redeemed LVAs have a magnification requirement of ≥ 1.5-fold and ≥ 6-fold. Furthermore, next to ophthalmologists, general practitioners and other medical specialists seem to play a role in LVA provision as well, which should be taken into account by policy makers when planning interventions for increasing LVS provision. Our findings provide a starting point to examine LVS provision in Germany.
