Background:Our aim was to evaluate the use of indwelling, intermittent and external urinary catheters in neurogenic and non-neurogenic bladder patients in the Netherlands from 1997 to 2018.Methods:Data were retrieved from a population-based cohort containing information about the extramural use of medical devices in the insured population in the Netherlands. The insured population increased from 9.9 million people in 1997 to 17.1 million people in 2018 (64–100% of the Dutch population). Users are expressed by users per 100,000 insured people and total users, corrected for the overall Dutch population. The expenditures are corrected for inflation and expressed by total costs and costs per user.Results:During this 21-year period, indwelling catheter (IC) users doubled from 159 per 100,000 people (24,734 users) to 315 per 100,000 people (54,106 users). Clean intermittent catheter (CIC) users increased from 92 per 100,000 people (14,258 users) in 1997 to 267 per 100,000 people (45,909 users) in 2018. Of all ...
