Overview of the steps used to develop the original PECCS, the translation process to develop PECCS-CA, and its’ application on administrative data of hospital encounters.
This figure presents an overview of the steps our research team used to develop PECCS, translate PECCS from ICD-10-CM to ICD-10-CA to be used in Canada (PECCS-CA), and its’ application on administrative data of hospital encounters in Ontario.

Diagram outlining the step-by-step procedure used to translate PECCS from ICD-10-CM to ICD-10-CA for use in Canada.
a The ICD-10 code description for A009 in ICD-10-CA and ICD-10-CM is ‘Cholera, unspecified’. b The ICD-10-CA code description for J47 is ‘Bronchiectasis’, and the ICD-10-CM code description for J479 is ‘Bronchiectasis, uncomplicated’. c The ICD-10-CA code description for H031 is ‘Involvement of eyelid in other infectious diseases classified elsewhere’, and the ICD-10-CM code description for H029 is ‘Unspecified disorder of eyelid’. d During the review, we aimed to retain as much of the PECCS categories for ICD-10-CA from the original PECCS categories from the ICD-10-CM. However, if needed, we also modified some categories by merging original PECCS categories that overlapped or created new categories to ensure that the codes fitted within the category.

Top 10 most prevalent conditions identified by applying PECCS-CA to administrative data of pediatric hospital encounters in Ontario, 2014–2019.
This figure focuses on the 10 most prevalent conditions in children with hospital encounters in Ontario during 2014–2019. Data for pediatric hospital encounters (inpatient discharges, same day surgery) were obtained from the Canadian Institute for Health Information Discharge Abstract Database (CIHI-DAD) and Same Day Surgery (SDS) database. (n = total number of hospital encounters for the condition; % = percentage of hospital encounters for the condition from all hospital encounters. The percentages displayed do not equal to 100%, because only the top 10 most prevalent conditions are presented).
