Utilizing Respiratory Therapists to Reduce Costs of Care.

INTRODUCTION: Changes to the reimbursement of respiratory care services over the past 26 years make it imperative that respiratory therapists (RTs) demonstrate cost savings to establish their value. Therefore, this systematic review evaluated the cost-related impacts from utilizing RTs to deliver care when compared to other care providers. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to guide the search process. The study addressed articles across all age groups and care settings that compared the cost of care provided by RTs to a comparison group. Studies were excluded if they were not written in English, described care provided outside of the United States, did not provide quantitative data, or lacked a comparison group. RESULTS: A total of 4,120 articles emerged from the search process, of which 60 qualified for a full text review. Cost savings were evaluated for the 28 articles included in this review, noting the study design, the specific respiratory care practice, use of protocols, clinical setting, and age group. The most frequently studied topic was mechanical ventilation, which along with disease management represented by the most randomized, controlled trials for the study design. The clinical practice area notably absent was home care. CONCLUSIONS: Although cost comparisons across studies could not be made due to the inconsistent manner in which data were reported, evidence demonstrated that care provided by RTs yielded both direct and indirect cost reductions, which were achieved through protocol utilization, specialized expertise, and autonomous decision making. The care provided was consistent with care provided by other disciplines. It is critical for the respiratory care profession to highlight key clinical practice areas for future research, to establish uniform reporting measures for outcomes, and to foster the development of future respiratory care researchers to affirm the value that respiratory therapists add to patient care.

Effects of a Highly Portable Noninvasive Open Ventilation System on Activities of Daily Living in Patients with COPD.

Background: For patients with chronic obstructive pulmonary disease (COPD), an increase in exercise tolerance and ability to perform activities of daily living (ADLs) can mean an improved quality of life with fewer exacerbations and lower health care expenses. We evaluated a wearable, noninvasive open ventilation (NIOV) system designed to enhance exercise capacity and increase mobility. Methods: Patients with stable, oxygen-dependent COPD were recruited for this prospective, open-label, crossover study. Inclusion criteria included supplemental oxygen use, elevated dyspnea score, and the ability to perform ADLs. Patients performed a selected ADL for as long as tolerable while using standard oxygen therapy. Following a rest period, the same ADL was repeated using the NIOV system. ADL endurance time, oxyhemoglobin saturation measured by pulse oximeter ( SpO2), dyspnea, fatigue, and discomfort scores were recorded. Results: Thirty patients were enrolled and 29 patients completed the study. Mean ADL endurance increased by 85% (13.4 vs. 7.2 min) using NIOV compared with oxygen therapy (p<0.0001). Mean SpO2 was significantly higher during ADLs using NIOV versus oxygen therapy (p<0.0001). Median dyspnea, fatigue, and discomfort scores were significantly lower using NIOV during ADLs compared to oxygen therapy (p<0.01). No device-related adverse events were observed. Conclusions: This study demonstrated that a novel, portable noninvasive open ventilation system can improve ADL performance in the home setting. Compared to standard oxygen therapy, the NIOV system provided statistically and clinically significant increases in ADL endurance time and oxygenation, while decreasing dyspnea, fatigue, and discomfort. The NIOV system appears to offer a practical option for increasing activity and exercise tolerance in oxygen-dependent patients with COPD.
