Comments Detailed

A patient is said to have CHF if they had one hospital admission (either from the DAD or from OMHRS) with a CHF diagnosis or an OHIP claim/NACRS ED record with a CHF diagnosis followed within one year by either a second record with a CHF diagnosis from an source. ICD 9 codes: 28, ICD 10 codes: I500, I501, I509 Further information on how this cohort was generated: The case-definition algorithm to identify patients with CHF links different databases at ICES National Ambulatory Care Reporting System (NACRS), and OHIP and is based on one hospital inpatient record with a CHF diagnosis (as defined by ICD 9 code: 428 or ICD10 codes: I500, I501, I509) or one ambulatory care record with a CHF diagnosis followed by a second record with a CHF diagnosis from any source within one year. The administrative data case-definition algorithm for CHF has a sensitivity of 85%, a specificity of 97%, and a PPV of 56%.2
