DRG 127 accounted for 84.3% of index hospitalisations identified using ICD-9-CM heart failure codes. Administrative discharge records may contain coding errors and diagnostic or procedural misclassification, limiting precision. The dataset lacked socioeconomic characteristics, outpatient care information, and postdischarge support measures, leaving residual confounding possible. Using DRG classification alone would underestimate the heart failure burden. Readmissions occurring outside the hospitals included in the administrative database may have been missed, potentially underestimating the true readmission rate. A mixed-effects multiple logistic regression model was used, adjusted for age and gender and accounting for clustering at the hospital level. Administrative data lacked several clinical and social variables relevant to opioid risk. The study used 2022 hospital discharge records from the Italian administrative hospital discharge flow (SDO) in north-east Italy, covering approximately 890,000 inhabitants. The study included adults in Alberta who received at least one community-pharmacy opioid dispensation from January 2019 through September 2023. The study used linked pharma…
