Multilevel Poisson regression on factors for avoidable readmissions on the total population at risk (all acute care hospitalizations which included: avoidable readmissions, unavoidable readmissions and no readmissions)

Factor	IRR	95.0% C.I.
No. of attendance to public outpatient clinics and A&E departments in the past 12 months	1.02*	(1.01 - 1.03)
No. of hospitalization in the past 12 months	1.08***	(1.05 - 1.10)
Length of stay (in days) of previous linked episode that induce the readmission	1.01*	(1.00 - 1.02)
Fee was not paid by public assistance	1.14	(0.87 - 1.49)

Notes:

(i) Regression adjusted for age, gender and principal diagnosis of previous discharge

(ii) * p-value < 0.05, ** p-value < 0.01, *** p-value < 0.001, IRR refers to incidence rate ratio, CI refers to Confidence Interval
