Health and functional status, health events, use of healthcare services and costs associated with overactive bladder among the medically complex vulnerable elderly in the US US

摘要

Summary Aims To assess the prevalence of overactive bladder ( OAB ) among medically complex vulnerable elderly ( MCVE ) patients in the United States and to compare health status measures, functional status, healthcare events, use of healthcare services and costs between MCVE patients with and without OAB . Methods Using the 2001‐2010 Medicare Current Beneficiary Surveys, we defined the MCVE as those respondents who were ≥65?years old with scores ≥3 on the Vulnerable Elders Survey‐13. OAB diagnosis codes or self‐reported use of antimuscarinic medications were used to identify MCVE individuals with OAB . Multiple regression analyses were used to estimate the adjusted relationship between OAB and the outcome measures. Results The annual prevalence of OAB among the MCVE increased from 9.6% in 2001 to 13.5% in 2010. MCVE individuals with OAB were more likely to have experienced falls or fractures (odds ratio [ OR ]?=?1.6; 95% confidence interval [ CI ]: 1.3‐2.0), urinary tract infections ( OR ?=?4.3; 95% CI : 3.5‐5.4), institutionalization ( OR ?=?1.9; 95% CI : 1.4‐2.5), limitations in activity of daily living ( ADL ) ( OR ?=?1.4; 95% CI : 1.1‐1.7) and instrumental ADL ( OR ?=?1.5; 95% CI : 1.2‐2.0), hospital admission ( OR ?=?1.6; 95% CI : 1.3‐2.0) and emergency department admissions ( OR ?=?1.6; 95% CI : 1.3‐2.0) than those without OAB . MCVE individuals with OAB incurred, on average, $7188 (2013 dollars) more in healthcare costs than those without OAB . Discussion/Conclusions The prevalence of OAB in the MCVE population increased over time. OAB is associated with substantial clinical and economic burden. Further research is warranted to understand whether better management of the MCVE population with OAB may reduce healthcare resource use.
