Asia Pediatric Intensive Care Epidemiology and Outcomes Study

Though the main methodology is recruitment of all pediatric ICU admissions, a pre-determined random sampling protocol is allowed for sites with limited in resources for recruitment and data collection. This protocol may involve recruitment of all admissions for 1year (52 weeks), all admissions for 1 month per quarter over 1 year (16 weeks), all admissions for 1 week per month over 1 year (12 weeks), all admissions for 2 weeks per quarter over 1 year (8 weeks) or all admissions for 1 week for quarter over 1 year (4 weeks) - this will be declared at the start of the study by each participating site before recruitment begins. This strategy will allow us to include sites with and without sufficient resources to be represented in this study.
