For the patient to qualify for reimbursement, a physician must certify a valid diagnosis of asthma, including objective documentation of variable airway obstruction.
The poor performance of the congestive heart failure model may suggest that for chronic disease conditions social and behavioral variables are of greater importance and improved documentation of these variables within the electronic health record should be encouraged.
The documentation of measured variables, methods, survey intervals and areas must be carried out according to standard methods and using a main meta-database or several interrelated databases.
Standardized model documentation protocols, such as ODD or TRACE (see section 'Literature review') propose simple tables and class diagrams using Unified Modeling Language (UML) [53] for the documentation of model variables.
A weakness with the Swedish MBR is the lack of systematic documentation of some variables (11).
Moreover, the identification of poor documentation of key variables is crucial to future quality improvement measurements.
This is at the heart of science: Minimize distraction and confounds, control and replicate, with careful documentation of the variables that were manipulated.
Furthermore, inadequate preoperative airway documentation has been shown to increase adverse airway events during anaesthesia [ 27] and standardised documentation of airway variables in anaesthesia records have been identified as important for patient safety [ 28, 29].
Accordingly, accurate assessment and documentation of important pathologic variables are essential.
We developed a web-based, high-granular research database for comprehensive documentation of all relevant variables to evaluate new surgical techniques.
Use of the proforma improved the documentation of the remaining 18 variables, including base excess, level of prehospital care and first key emergency intervention.
