Risks Associated With Conventional Humidifiers Adapted for High-Flow Nasal Cannula Therapy in Human Infants: Results of a Time and Motion Study.
Robert Tero and colleagues conducted a time and motion study assessing workflow and staff effort needs between the purpose-built Vapotherm system and the conventional Fisher & Paykel technology for the delivery of High Flow Nasal Cannula (HFNC) Therapy. The objective was to compare the actual cost of operating each system when taking into account the effort needed to manage the device, including tending to the rainout for which the conventional technology is prone.
While the data did reveal significantly more therapist contacts and unscheduled interventions associated with the need to clear condensed water from the circuit, an important finding in the paper was the resulting clinical sequelae associated with condensate reaching the patient. The Fisher & Paykel devices were associated with 0.7 device-related clinical events per 8 hour window of observation. These events ranged from patient arousals to more serious effects such as apneic and bradycardic events.
The authors conclude that the use of conventional technologies is associated with an unaccounted cost beyond circuit price related to staff resources and the risk of clinical events. These costs should be accounted for when assessing the operational cost of the technology platform.
