Investigation into the causes of indwelling urethral catheter implementation and its effects on clinical outcomes and health care resources among dementia patients with pneumonia: A retrospective cohort study.

Those with indwelling urethral catheters had significantly longer LOS, except for those in the PS match model, where they tended to have longer LOS although this did not reach statistical significance (bivariate analysis: 0.08 [0.05–0.11] P < 0.001, RA model: 0.07 [0.04–0.10] P < 0.001, PS match model: 0.04 [0.00–0.08] P = 0.067, and PS stratification model: 0.06 [0.03–0.09] P < 0.001). 3.4 Results of sensitivity analyses The results of the generalized linear model with clustering care facilities were similar to those of model 2 (Supplemental Digital Content 1).
