These elements include the background of the instrument, intended population, respondent and administrative burden, reliability and validity, scoring convention, and reported analyses.
This research addresses an important methodological issue on patient safety and obesity for the purposes of examining clinical and administrative data for the reliability of using International Classification of Diseases (ICD) diagnoses codes alone to reliably identify obesity as a comorbidity and risk factor in care and management.
Where additional information was known, it was used to supplement the hospital administrative data to increase reliability.
Most previous research has been conducted in administrative databases of uncertain reliability and/or on specific sub-populations.
Coverage data from the PEC survey was compared with tally sheet data and population projections to determine the reliability of administrative data.
Sustainability criteria of administrative green schools need validity, reliability and norms.
The reliability of using administrative data to differentiate Alzheimer's disease, vascular dementia or mixed dementia is questionable.
Earlier research has shown the reliability of using administrative data in relation to clinical data.
Important limitations include the largely white men and older population, the reliability of the administrative data set, and the selection and ascertainment bias related to patients for whom HbA1c testing was performed.
None of the validation measures varied over time for any of the data sources indicating the reliability of the administrative data sources, even over a time period in which coding systems changed.
The use of administrative databases showed a high reliability in that we were able to retrieve the whole medical history and treatment pattern of each single patient; moreover, the linkage among administrative databases is simple to perform and does not require a specific epidemiological organization; thus the cost is very low.
