Comparison of Events Between Patients With SDP and Controls^a,b

Event	Control (N=5133)		SDP (N=2703)		P value
	n (%)	95% CI	n (%)	95% CI
Event within 96 h
Unplanned readmission	50 (0.97)	0.72%-1.28%	28 (1.04)	0.69%-1.49%	.79
Unplanned procedure-related readmission	7 (0.14)	0.05%-0.28%	2 (0.07)	0.01%-0.27%	.45
Event within 24 h
Unplanned readmission	27 (0.53)	0.35%-0.76%	10 (0.37)	0.18%-0.68%	.34
Unplanned procedure-related readmission	6 (0.12)	0.04%-0.25%	2 (0.07)	0.01%-0.27%	.57

^aSDP = sedation dismissal process.

^bData are summarized as n (%) with exact 95% binomial CIs. P values are from generalized estimating equations accounting for the matched set design. Unplanned admission is defined as either unplanned hospital admission or unplanned visit to the emergency department within 96 h. Some patients presented to the emergency department and were subsequently admitted to the hospital and these were counted as a single event. For 5% of patients, follow-up was truncated at the time of a scheduled return visit occurring within 96 h.
