  • A data quality assessment to inform hypertension surveillance using primary care electronic medical record data from Alberta, Canada

    Open AccessStephanie Garies, Kerry McBrien et al.ARTICLEBMC Public Health2021

    Blood pressure and prescribed medications in primary care EMR data demonstrated good completeness and plausibility, and contribute valuable information for hypertension epidemiology and surveillance. The use of other clinical, laboratory, and sociodemographic variables should be used carefully due to variable completeness and suspected data errors. Additional strategies to improve these data at the point of entry and after data extraction (e.g. s…

  • Constructing Episodes of Inpatient Care

    Mingkai Peng, Bing Li et al.ARTICLEMedical Care2017Referencias: 13

    BACKGROUND: Hospital administrative health data create separate records for each hospital stay of patients. Treating a hospital transfer as a readmission could lead to biased results in health service research. METHODS: This is a cross-sectional study. We used the hospital discharge abstract database in 2013 from Alberta, Canada. Transfer cases were defined by transfer institution code and were used as the reference standard. Four time gaps betwe…

  • A Modification of the Elixhauser Comorbidity Measures Into a Point System for Hospital Death Using Administrative Data

    Carl van Walraven, Peter C Austin et al.ARTICLEMedical Care2009Referencias: 16

    BACKGROUND: Comorbidity measures are necessary to describe patient populations and adjust for confounding. In direct comparisons, studies have found the Elixhauser comorbidity system to be statistically slightly superior to the Charlson comorbidity system at adjusting for comorbidity. However, the Elixhauser classification system requires 30 binary variables, making its use for reporting and analysis of comorbidity cumbersome. OBJECTIVE: Modify t…
