Randomized control trial comparing an Alvarado Score-based management algorithm and current best practice in the evaluation of suspected appendicitis

Table 3 Comparison of secondary outcome measures

	Intervention arm (n = 80)	Usual care arm (n = 80)	P value
Missed diagnosis	0 (0.0)	0 (0.0)
Histological-proven appendicitis among the subjects who had surgery*	28 (87.5)	27 (90.0)	0.866
Negative appendectomy among the subjects who had surgery*	4 (12.5)	3 (10)	0.926
Length of stay in days
Median (range)	2 (1–14)	2 (0–13)	0.705
Gross cost of stay (S$)
Median (range)	3973 (2092–26009)	3703 (1724–27321)	0.886

*Percentages calculated using number of patients who underwent surgery in each arm (32 in intervention arm, 30 in the control arm) as denominator
