Adherence to professional society guidelines among women with stress or mixed urinary incontinence

Abstract

Aims: The objective of this analysis was to describe longitudinal adherence with recommended urinary incontinence (UI) evaluation and treatment guidelines over a 2-year period in patients newly diagnosed with stress (SUI) or mixed UI (MUI), and average 2-year cost associated with initial treatment. Methods: A retrospective claims analysis using the IBM MarketScan database was conducted. Women diagnosed with SUI/MUI between July 1, 2014 and June 30, 2016 were identified using the International Classification of Diseases (ICD) 9 and 10 codes for SUI or MUI. Newly diagnosed SUI/MUI patients who did not have a UI-related diagnosis for at least 1 year before their index date were assessed. Results: 103 813 patients with newly diagnosed SUI or MUI were identified. Of those, 96.15% (99 821/103 813) received an initial evaluation in accordance with professional guidelines (e.g., patient history, physical examination, urinalysis). Only 6.8% (5086/74 925) and 7.7% (2229/28 888) of patients with SUI and MUI, respectively, received a first-line behavioral treatment (e.g., pelvic floor muscle exercises, bladder training), according to guidelines. The 2-year average UI-related medical costs associated with guideline adherence for SUI were $5770.93 ± $9454.81 and for MUI, $4416.16 ± $7401.53. Nonadherence was observed in 59.2% (44 382/74 925) of SUI and 64.1% (18 530/28 888) of MUI patients. Two-year average UI-related medical costs for the nonadherent group were $8568.00 ± $11 275.52 for SUI and $6986.66 ± $10 765.55 for MUI, significantly more than the adherent group (p < 0.0001). Conclusion: The majority of SUI or MUI patients do not receive a documented behavioral intervention as their first-line treatment, which is a recommendation by professional society guidelines. This was found to affect the cost burden for payers; those that were nonadherent had significantly higher costs 2-year postindex.
