A computer-aided audit system for respiratory therapy consult evaluations: description of a method and early results

Use of respiratory therapist (RT)-guided protocols enhances allocation of respiratory care. In the context that optimal protocol use requires a system for auditing respiratory care plans to assure adherence to protocols and expertise of the RTs generating the care plan, a live audit system has been in longstanding use in our Respiratory Therapy Consult Service. Growth in the number of RT positions and the need to audit more frequently has prompted development of a new, computer-aided audit system.

The number and results of audits using the old and new systems were compared (for the periods May 30, 2009 through May 30, 2011 and January 1, 2012 through May 30, 2012, respectively). In contrast to the original, live system requiring a patient visit by the auditor, the new system involves completion of a respiratory therapy care plan using patient information in the electronic medical record, both by the RT generating the care plan and the auditor. Completing audits in the new system also uses an electronic respiratory therapy management system.

The degrees of concordance between the audited RT's care plans and the "gold standard" care plans using the old and new audit systems were similar. Use of the new system was associated with an almost doubling of the rate of audits (ie, 11 per month vs 6.1 per month).

The new, computer-aided audit system increased capacity to audit more RTs performing RT-guided consults while preserving accuracy as an audit tool. Ensuring that RTs adhere to the audit process remains the challenge for the new system, and is the rate-limiting step.
