Effectiveness of a shared decision-making program in reducing unplanned dialysis in advanced chronic kidney disease: a retrospective cohort study

Table 3 Comparison of the proportion of unplanned dialysis in patients with end stage kidney disease undergoing renal replacement therapy before and after implementing the Shared Decision-Making program

Primary endpoint	Usual care (n = 45)	Receive SDM (n = 66)	Multivariate analysis odds ratio (95% CI)^†	P value	Propensity score–weighted analysis odds ratio (95% CI)^‡	P value
Primary endpoint	number (percent)
Unplanned dialysis	30 (66.67%)	22 (33.33%)	0.19 (0.07–0.47)	0.001	0.19 (0.10–0.36)	<0.001

^† The odds ratios with 95% confidence intervals and P-values were calculated using a logistic regression model to compare patients receiving the SDM program with those receiving usual care, adjusting for sex, age, diabetes mellitus, cardiovascular disease, cancer, late referral dialysis modality, serum bicarbonate, and serum albumin at dialysis initiation
^‡ Propensity score–weighted analysis was conducted using generalized boosted models to estimate propensity score weights, accounting for potential confounders in the two groups
