Backgrounds. - This study aims to estimate the impact of preventing urinary tract infections (UTI), using a strategy of increased water intake, from the payer's perspective in the French health care system.
Methods. - A Markov model enables a comparison of health care costs and outcomes for a virtual cohort of subjects with different levels of daily water intake. The analysis of the budgetary impact was based on a period of 5 years. The analysis was based on a 25-year follow-up period to assess the effects of adequate water supply on long-term complications.
Results. - The authors estimate annual primary incidence of UTI and annual risk of recurrence at 5.3% and 30%, respectively. Risk reduction associated with greater water intake reached 45% and 33% for the general and recurrent populations, respectively. The average total health care cost of a single UTI episode is (sic)1074; for a population of 65 millions, UTI management represents a cost of (sic)3.700 millions for payers. With adequate water intake, the model indicates a potential cost savings of (sic)2.288 millions annually, by preventing 27 million UT! episodes. At the individual level, the potential cost savings is approximately (sic)2915.
Conclusions. - Preventing urinary tract infections using a strategy of adequate water intake could lead to significant cost savings for a public health care system. Further studies are needed to assess the effectiveness of such an approach.
