Research Subject Perceptions Regarding Infection Control Procedures to Reduce COVID-19

Introduction The COVID pandemic has altered health care delivery, including clinical research, by introduction of measures to reduce COVID. How these measures affect clinical research participation is unclear. Objectives The purpose of this survey was to document research volunteer's attitudes toward COVID infection control procedures. Methods Our research program implemented the following: 1. Staff wore masks, disposable gowns, face shields and gloves when with subjects. 2. Subjects were asked if they tested positive or were experiencing COVID symptoms; upon entry their temperature was measured, and hand sanitizer used. 3. Disinfecting was expanded to all scanner room surfaces in contact with humans between each visit. 4. Only 1 subject was allowed in the research office at a time. Staff, when possible, remained > 6 feet away from other persons. As part of a study evaluating total body DXA, community dwelling volunteers completed a self-administered health care delivery preference survey from Dec 2020 to May 2021. A 5-point scale was used to capture responses to 10 questions (Table 1). Responses were tested using Chi Square with age and sex comparisons assessed by ANOVA. Results Eighty-two adults (41F/41M) mean (SD) age 50.9 (18.3) yrs (range 18-79) without sex difference participated. Participants strongly agreed (84%; p < 0.001) they were more comfortable seeing effort to prevent COVID-19; 72% agreed 1 subject, without a companion, should be seen, and 81% strongly agreed masks be required. Seeing staff clean visit space was important to 66%, more so among women (33%) than men (21% (p = 0.007)). Most subjects (83%) reported comfort having elective procedures and did not feel “unclean” or “diseased” (87%) by procedures. Some, 26%, preferred a non-hospital setting, 66% were neutral; those age 50+ (17%) preferred this more (p = 0.004) than younger subjects (5%). Finally, 91% preferred to have a brief test description before visit arrival. Conclusions In this university-based study, most subjects favored masking, cleaning and limiting personal contact for research visits. Notably, no information regarding vaccination status was exchanged and the study began just as vaccines became available and ended just after all US citizens over age 16 were eligible for vaccination. Thus, it is unknown if vaccination status might alter research participation perception. However, people do prefer that steps are taken to reduce infection in research settings. It seems likely that this would be the case in clinical care settings.
