ObjectiveTo assess the impact of a respiratory therapy consult service (RTCS) on practices and appropriateness of ordering respiratory care services.DesignNonrandomized prospective observational cohort study with concurrent controls.SettingAdult non-ICU inpatient wards of an academic medical center.PatientsA convenience sample of 98 adult non-ICU inpatients at the Cleveland Clinic Hospital, representing 20 inpatient clinical services. Patients whose respiratory care plans were determined by respiratory care practitioners using sign and symptom-based algorithms to specify treatment comprised the treatment group (n = 51, respiratory therapy consult group). The nonconsult group (n = 47) were patients whose respiratory care plans were specified by their own physicians.InterventionSpecification of the respiratory care plan by the RTCS vs by the physicians themselves. Use of the RTCS was at the discretion of the managing physician.Outcome MeasuresTypes and number of respiratory care treatments, length of hospital stay, costs of the respiratory therapy provided, appropriateness of respiratory care orders (based on comparison of the actual respiratory care orders with a reference respiratory care plan generated by a study investigator who was kept blind to the actual respiratory care plan), and adverse respiratory events.ResultsPatients for whom the RTCS was requested by their physicians had a greater severity of respiratory illness based on having a lower triage score, but were otherwise similar at baseline. Fewer initial orders for respiratory care were discordant with the reference algorithms in RTCS patients (15% +/- 26% [SD]) than in nonconsult patients (43% +/- 36%; p < 0.001), and a smaller fraction of RTCS patients received at least one discordant initial respiratory care order (37% vs 72%; p < 0.001). Though provided to sicker patients with longer lengths of hospital stay, RTCS-directed care incurred similar respiratory care costs per patient ($335.63 +/- $272.69 [RTCS] vs $349.06 +/- $273.27; p = 0.72).ConclusionsThese results suggest that the RTCS can be an effective strategy to allocate respiratory care strategies appropriately while conserving the costs of providing respiratory care.
