Table 2 Impact of quality improvement interventions on 72-hour supervised fasting test performance and C-peptide utilization across study phases

Cycle	n	Median age (years)	Median LOS	Correct test (%) with 95%CI¹	C-peptide (total)	Average C-peptide per patient
Baseline	9	34.5 (mean)	5 (4-6)	33.3 (12.1-64.6)	36	4.0
PDSA 1	5	29 (20-35)	4 (4-5)	80 (37.6-96.4)	6	1.2
PDSA 2	3	26 (25-42)	4 (4-4)	100 (43.9-100)	3	1.0

¹Confidence intervals were calculated using the Wilson score intervals.

LOS: Length of stay; CI: Confidence intervals; PDSA: Plan-do-study-act.
