Objective: Response to the coronavirus/COVID-19 pandemic has resulted in several initiatives that directly impact hospital operations. There has been minimal information on how COVID-19 has affected exercise testing in pediatric patients. Design: A web-based survey was designed and sent to pediatric exercise testing laboratories in the United States and Canada. Questions were designed to understand the initial and ongoing adaptations made by pediatric exercise testing laboratories in response to COVID-19. Results were analyzed as frequency data. Results: There were responses from 42% (35/85) of programs, with 68% (23/34) of laboratories discontinuing all exercise testing. Of the 23 programs that discontinued testing, 15 (65%) are actively working on triage plans to reopen the exercise laboratory. Personal protective equipment use include gloves (96%; 25/26), surgical masks (88%; 23/26), N-95 masks (54%; 14/26), face shields (69%; 18/26), and gowns (62%; 16/26). Approximately 47% (15/32) of programs that typically acquire metabolic measurements reported either ceasing or modifying metabolic measurements during COVID-19. Additionally, 62% (16/26) of the programs that previously obtained pulmonary function testing reported either ceasing or modifying pulmonary function testing. Almost 60% of respondents expressed a desire for additional guidance on exercise laboratory management during COVID-19. Conclusions: Pediatric exercise testing laboratories largely closed during the early pandemic, with many of these programs either now open or working on a plan to open. Despite this, there remains heterogeneity in how to minimize exposure risks to patients and staff. Standardization of exercise testing guidelines during the COVID-19 pandemic may help reduce some of these differences.

Background:Children may undergo exercise testing for multiple reasons. Exercise testing measures multiple physiologic parameters when the body is under stress and can be performed by cycle or treadmill protocols. A higher oxygen consumption (VO2) has been noted by treadmill protocols. The oxygen uptake efficiency slope (OUES) and slope of ventilation to carbon dioxide (VE/VCO2) are newer parameters of cardiopulmonary response. Differences in OUES and VE/VCO2 slope have not been compared in regards to method of testing.Methods:Clinical exercise tests performed by graded treadmill (Treadmill group) were compared with those performed by cycle ergometer (Cycle controls) from a previous study carried out at a separate institution. Exercise testing of persons with cystic fibrosis (Cycle CF) was evaluated during the same study. Age, weight, height, body mass index, sex, pulmonary function, maximal heart rate, VO2max, VEmax, end tidal carbon dioxide (ET-CO2), OUES and VE/VCO2 slope were compared by unpaired student’s T-test among the three groups. Pearson product moment correlations compared VO2max, OUES and VE/VCO2 slope in all three study groups.Results:The Treadmill group and Cycle controls had similar age, height, weight, BMI and baseline pulmonary function. The Cycle CF group had lower height, weight and BMI but similar age and pulmonary function to the other two groups. VO2max, and VEmax were significantly higher in Treadmill group than cycle controls. OUES was higher in the Treadmill group than cycle controls (p=0.07). Correlation between VO2max and OUES was 0.89 in treadmill group, 0.96 in cycle controls and 0.93 in cycle CF.Discussion:This study suggests OUES and VO2max, are highly correlated in healthy controls whether obtained by cycle or treadmill protocols. Variation in the level of correlation between VE/VCO2 slope and VO2max existed in the three study populations. VE/VCO2 slope correlated highest with end tidal carbon dioxide at maximal exercise and this may confound the use of the VE/VCO2 slope in healthy populations. No clear advantage to testing by treadmill or cycle ergometry was determined in this study and testing can be determined based on institutional preference.
