Table 3.

The rate of readmissions within 30 and 90 days

		Without PIMs group (n = 304)	No suggestions group (n = 115)	Suggested group (n = 125)	P values
					Without PIMs group vs Suggested group	No suggestions group vs Suggested group	Without PIMs group vs No suggestions group
Readmissions within 30 days	n (%)	10 (3.3)	1 (0.9)	7 (5.6)	0.28	0.068	0.30
Readmissions within 90 days	n (%)	24 (7.9)	2 (1.7)	9 (7.2)	1.00	0.062	0.021

The Fisher’s exact test followed by Bonferroni correction was used to compare the proportions of categorical variables between three groups, and P values < 0.017 were considered to indicate statistical significance
