Guidelines regarding face mask use have evolved from the time when COVID-19 first emerged. Practices for face mask use in the United States vary widely. METHODS: Clinical and nonclini- cal staff from a pediatric health care system were invited to complete a survey regarding percep- tions and practices of face mask use during the COVID-19 pandemic. Overall results were analyzed, and subgroup analyses were conducted to compare clinical and nonclinical staff, and clinical staff who do and do not provide direct patient care. RESULTS: The response rate was approximately 24\% (1,128 of 4,698). Most respondents were clinical staff who provide patient care. A surgical/procedure mask was most often worn for patient care by 72\% (P < .001). Most respondents (70\%) reported wearing a cloth mask when not in the hospital (P < .001). Cloth masks were worn for a mean of 3.4 6 3.9 d before washing. Frequent hand hygiene before put- ting on the mask, before removing, and after removing was reported as 56\%, 44\%, and 62\%, respectively. The most common challenges reported were glasses fogging (69\%), skin irritations (45\%), and headaches (31\%). Qualitative data revealed themes of feeling unsafe, beliefs and practices about COVID-19 and masks, mandates and enforcement of wearing masks, availability of personal protective equipment, and care delivery challenges. CONCLUSIONS: Practices and perceptions of face masks varied among staff in a pediatric health care system. Some staff did not feel that masks are effective in preventing virus spread, and others did not feel safe in per- forming job duties. Hand hygiene for mask handling was not practiced consistently. A large number of staff reported having experienced challenges or health issues when wearing a mask. Clinical staff who provide direct patient care reported more issues than both nonclinical and clinical staff who do not provide care.

Initially, both the WHO and the US Centers for Disease Control and Prevention (CDC) did not support universal masking for healthy individuals, and the US Surgeon General even advised against purchasing face masks.4,5 However, the rationale for this was to help Ms Willis, Mr Lovenstein, Ms Honeycutt, and Dr Walden are affiliated with Arkansas Children’s Hospital, Little Rock, Arkansas.

JULY 2021 VOL 66 NO 7 ensure supplies were available for health care workers.4 On April 3, 2020, the CDC recommended cloth face coverings for the general public to help decrease the spread of COVID- 19.3 Face mask utilization to aid in decreasing transmission of respiratory viruses is not a new concept. During the 1918 influenza pandemic, the medical community urged the use of face masks, but the idea was met with resistance even at that time (https://www.historyextra.com/period/ 20th-century/wear-face-masks-backlash-opposition-why- spanish-flu-coronavirus-covid-history/, Accessed May 3, 2021). An Australian clinical trial published in 2009 found that household adherence to mask use significantly reduced the risk for influenza-like illnesses.6 Despite lim- ited evidence to support universal masking to decrease the spread of COVID-19,7,8 practices for face mask use in the United States vary widely and has become a controversial topic.3 In Asian countries, face mask use is more accepted as compared to Western countries.5 A study that evaluated the effects of state mask mandates in the United States early in the pandemic found a reduction in the COVID-19 daily growth rate.9 While several states and localities have executed a face covering mandate, there were still some states without a mask requirement even as cases surged during the winter season of 2020 (Cable News Network: December 8, 2020. https://www.cnn.com/2020/ 11/09/us/biden-mask-mandate-nationwide-trnd/index.html, Accessed January 15, 2021). In states where face mask use is mandated, it is often not enforced, and practices are inconsistent and lack uniformity.3 Several states that had a mandate began to relax mask requirements as early as February 2021. Arkansas Children’s Hospital (ACH) is part of a pediatric health care system that includes 2 hospitals, numerous clin- ics, a pediatric research institute, and a foundation for educa- tion and outreach. ACH has an academic affiliation with the University of Arkansas for Medical Sciences (UAMS) and is a teaching hospital for the university’s department of pedia- trics. ACH implemented a mask requirement for all staff, patients, and visitors > 2 y old in late April 2020. This occurred prior to a July 2020 directive from the Arkansas Department of Health requiring face coverings.10 At ACH, staff are provided masks and appropriate perso- nal protective equipment (PPE) for patient care. However, staff who are not involved in patient encounters must pro- vide their own mask. Due to variable state, local, and indi- vidual practices for face mask use, a survey was developed to explore staff perceptions and practices of mask wearing in a pediatric health care system. The aims of this study were to evaluate perceptions of face mask use by staff dur- ing the COVID-19 pandemic and to determine if there were differences between clinical and nonclinical staff and between clinical staff who provide direct patient care and those who do not. Methods This was a descriptive, exploratory research study using survey methodology to examine the practices and percep- tions of face mask use by staff within an academic, pediatric health care system in Arkansas. An extensive literature search of major databases including PubMed and CINAHL did not reveal an instrument that specifically addressed the practices and perceptions of wearing face masks by health care staff during the COVID-19 pandemic. Therefore, an original 37-item instrument was developed for this study, and the survey was administered in REDCap, a secure web application for building and managing online surveys and databases. The actual number of items varied and depended upon responses and question logic technology. The survey domains included the type of face mask worn, mask care and handling, and challenges or health issues experienced with mask wearing. Demographic data included age, gender, race, ethnicity, and type of role (eg, clinical or nonclinical and direct patient care or not direct patient care). There was also an optional open response item to describe other concerns related to face mask use. The survey was peer-reviewed to assess the face validity and to evaluate relevance and clarity of survey items and associated responses. Approval to conduct the study was granted by the UAMS institutional review board. Eligible subjects included clinical and nonclinical staff working on any ACH campus or an affiliated clinic. Clinical roles were defined as positions involving the direct observa- tion and treatment of patients such as respiratory therapists, nurses, physicians, and other allied health professionals, as well as clinical staff who do not provide direct patient care. QUICK LOOK Current knowledge Universal masking is recommended to help mitigate the spread of COVID-19. There are several different types of face masks available for use. The CDC has issued recommendations for hand hygiene associated with mask handling and frequency of replacement or washing of cloth masks. What this paper contributes to our knowledge The majority of staff from a pediatric health care sys- tem reported wearing a cloth mask when not in the work area. Inconsistent hand hygiene for handling and washing cloth masks was noted. Many staff also identi- fied issues and health challenges associated with mask wearing. Clinical staff who provide patient care reported more issues than nonclinical and clinical staff who do not provide direct patient care. FACE MASK USE DURING COVID-19 RESPIRATORY CARE ! JULY 2021 VOL 66 NO 7 1097 Nonclinical roles were defined as individuals who may sup- port patient care but were not involved in the direct observa- tion and treatment of patients (eg, administrative, clerical, billing, housekeeping, maintenance). Academic students, contract agency personnel, hospital volunteers, and employ- ees < 18 y old were excluded from the study. Subjects were recruited electronically through e-mail and advertisements posted in non-patient-care areas. Invitations to complete the anonymous, web-based survey were sent to departmental e-mail distribution groups, sys- tem-wide daily digest e-mail announcements, flyers distrib- uted in non-patient-care areas, and internal social media postings. A hyperlink to access the survey was included on all invitations. The survey was available for a 2-week pe- riod from July 22 to August 5, 2020. Attempts were made to reach the entire target population of staff throughout the health care system. An estimate of 4,698 staff members, including UAMS staff working on any ACH campus, was obtained from the human resources department. Assuming a population of 5,000 staff, an alpha level of 0.05, and a margin of error of 0.03, the minimum sample size of returned surveys was expected to be 1,200.11 Frequency counts and percentages of responses were calcu- lated for each survey item to describe the results. Responses to the open-ended question were independently coded and organized into thematic categories. To determine if categorical responses differed signifi- cantly between clinical and nonclinical staff as well as clin- ical staff providing direct patient care versus clinical staff with no patient care, chi-square or Fisher exact test were conducted as appropriate. For items that yielded continuous responses, either t tests, when parametric assumptions were met, or Wilcoxon rank-sum test for nonparametric data were performed. A 2-tailed P < .05 was considered statisti- cally significant. All analyses were conducted in the SAS 9.4 (SAS Institute, Cary, North Carolina). Results There were 1,128 respondents, yielding a response rate of 24\% (1,128 of 4,698). Results from 117 subjects were excluded due to incomplete responses. The majority of respondents were female (n # 847, 84\%), clinical staff (n # 788, 78\%), in the age range of 35–44 y (n # 291, 29\%), white (n # 282, 82\%), and non-Hispanic ethnicity (n # 873, 86\%). Nurses accounted for over half of all clini- cal staff (n # 418, 53\%). Administrative type roles were the most common among nonclinical staff (n # 70, 32\%). Of all clinical staff, 607 (77\%) provided direct patient care. Table 1 includes demographic characteristics of the respondents. Table 2 provides detailed role types. There were 731 (72\%) subjects who reported that the institution provided the mask worn at work. This was sig- nificant for clinical staff (P < .001). A surgical/procedure mask was most often worn for patient care, according to 728 (72\%) respondents (P < .001). The mean number of days a surgical/procedure mask was worn before replacing was 2.9 6 3.2 d. Those who wore a N95 filtering facepiece respirator reported wearing it for a mean of 15.5 6 20 d before replacing. The majority of respondents (n # 703, 70\%) wear a cloth mask outside of the hospital (P < .001). Cloth masks were worn for a mean of 3.4 6 3.9 d before washing. Regarding the type of cloth mask, a sewn mask was worn by 474 (47\%) respondents, while 381 (38\%) purchased a cloth mask. Only 8 (1\%) subjects reported wearing a no-sew cloth mask. There were 83 (12\%) respondents who used a filter with the cloth mask. The filter was replaced after a mean of 3.8 6 6.0 d. The surgical/procedure mask was worn outside the hospital by 268 (27\%) respondents. One percent or less reported wearing either an allergy/dust mask, N95, combination of different masks, or no mask at all outside of the hospital setting. Table 1.

FACE MASK USE DURING COVID-19 1098 RESPIRATORY CARE ! JULY 2021 VOL 66 NO 7 Most respondents (n # 875, 87\%) indicated that masks are frequently replaced when damp or wet. Frequent hand hygiene before putting on the mask, before removing, and after removing was reported by 568 (56\%), 441 (44\%), and 628 (62\%) respondents, respectively. Additional informa- tion on mask handling is included in Table 3. Forty-six percent (n # 462) of respondents reported the most common method for mask handling during lunch or breaks was placing the mask in a nonshared area such as a pocket, purse, or locker. Other respondents reported placing their mask on a shared surface such as the break room table (n # 248, 25\%), pulled down under the chin to eat (n # 159, 16\%), or placing in a paper or plastic bag (n # 151, 15\%). Other methods were noted by 157 (16\%) respond- ents, such as placing their mask on a paper towel, moving the mask to the back of the neck, hanging the mask on a badge or string around their neck, hanging from one ear, hanging on a hook in a private office, or discarded and replaced. The predominant reason to wear a mask was to protect others (n # 506, 50\%). Additional reasons included to pro- tect self (n # 264, 26\%), hospital policy (n # 204, 20\%), and other reasons (n # 36, 4\%). Other main reasons for wearing a mask were a combination of protect self and others, to protect those at risk, and the state mandate. The majority of respondents (n # 760, 76\%) agreed that masks are effective in preventing the spread of COVID-19. Many respondents (n # 778, 78\%) reported they also believe that N95 masks protect the wearer from contracting COVID-19. Most subjects (n # 682, 68\%) felt safe when performing job duties with the type of mask worn at work. Several challenges were associated with mask wearing. The most common issues reported were glasses fogging (n # 701, 69\%), skin irritation (n # 456, 45\%), headache (n # 316, 31\%), and difficulty breathing (n # 294, 29\%). Other notable issues or health challenges were vision obstruction (n # 255, 25\%), claustrophobia (n # 152, 15\%), and allergies (n # 138, 14\%). Some respondents (n # 124, 12\%) did not report any challenges related to wearing a mask. Table 4 includes a detailed list of all reported issues and health challenges. Data from the open-ended question revealed 5 top themes and 32 subthemes (Table 5). The top 5 themes were staff feel unsafe, beliefs/practices about COVID-19 and mask use, mandates/enforcement of wearing masks, avail- ability of masks/PPE, and care delivery challenges. Themes and illustrative quotes are available as supplementary mate- rials (available at http://www.rcjournal.com). Clinical Versus Nonclinical Staff Significant differences between staff types were observed for mask replacement when damp or wet, hand hygiene, beliefs about mask protection, and issues or health challenges with mask wearing. Clinical staff were more likely to replace the mask when damp or wet compared to nonclinical (clinical n # 707, 90\%; nonclinical n # 166, 75\%; x2 # 31.59, P < .001). There were differences in the number of days a cloth mask was worn before washing. Nonclinical staff reported washing the mask slightly more often than their clinical colleagues, although this difference did not reach statistical significance (nonclinical 3.3 6 5.3 d; clinical 3.4 6 3.4 d, P # .07). Overall, clinical staff performed hand hygiene with mask handling more often than nonclinical staff. Hand hygiene is performed frequently before putting on a mask (clinical n # 461, 58\%; nonclinical n # 106, 48\%; x2 # 10.98, P # .03), before removing (clinical n # 371, 47\%; nonclinical n # 70, 32\%; x2 # 20.49, P < .001), and after removing it (clinical n # 504, 64\%; nonclinical n # 123, 56\%; x2 # Table 2.

FACE MASK USE DURING COVID-19 RESPIRATORY CARE ! JULY 2021 VOL 66 NO 7 1099 14.25, P # .006). Both groups of respondents more com- monly reported performing hand hygiene after removing their masks. For mask handling during lunch or a break, clinical staff were more likely to place the mask on a shared common surface (clinical n # 210, 27\%; nonclinical n # 38, 17\%; x2 # 8.44, P # .003), whereas nonclinical staff were more likely to place their mask in a nonshared area (nonclinical n # 122, 55\%; clinical n # 340, 43\%; x2 # 9.82, P # .001). Results were similar in both groups for the main reason a mask is worn. Most respondents stated the mask was worn primarily to protect others (clinical n # 388, 49\%; nonclini- cal n # 118, 53\%; x2 # 4.57, P # .20). Slightly more non- clinical than clinical staff agreed that correctly worn masks are effective in preventing the spread of COVID-19, but the difference was not statistically significant (nonclinical n # 177, 80\%; clinical n # 583, 74\%; x2 # 4.59, P # .33). A significantly greater percentage of clinical staff felt that N95 masks worn while caring for patients confirmed posi- tive or under investigation for COVID-19 protected them from contracting the virus compared to nonclinical staff (clinical n # 642, 82\%; nonclinical n # 136, 62\%; x2 # 45.09, P < .001). There were no differences between staff types in feeling safe in performing job duties with the mask worn at work (clinical n # 525, 67\%; nonclinical n # 156, 71\%; x2 # 3.49, P # .47). Clinical staff overall reported more issues or health chal- lenges associated with mask wearing including glasses fog- ging (clinical n # 576, 73\%; nonclinical n # 125, 56\%; x2 # 22.72, P < .001), skin irritation (clinical n # 390, 49\%; nonclinical n # 66, 30\%; x2 # 27.16, P < .001), and headache (clinical n # 276, 35\%; nonclinical n # 40, 18\%; x2 # 23.20, P < .001). More nonclinical than clinical staff reported issues with difficulty breathing (nonclinical n # 77, 35\%; clinical n # 217, 28\%; x2 # 4.33, P # .037). Nonclinical staff were also more likely to report having no issues or health challenges with wearing a mask than clini- cal staff (nonclinical n # 44, 20\%; clinical n # 80, 10\%; x2 # 15.09, P < .001). Clinical Patient Care Versus No Patient Care The majority of clinical respondents indicated they pro- vide direct patient care. There were few significant differ- ences between clinical staff providing patient care and those who do not for most domains except hand hygiene and health challenges with mask wearing. Clinical staff providing direct patient care reported more frequent hand hygiene before the removing their mask than did clinicians who do not provide patient care (patient care n # 293, 48\%; no patient care n # 79, 43\%; x2 # 11.87, P # .01). More clinicians who did not provide direct patient care indicated the main reason for wearing a mask is to protect others, but the difference was not significant (no patient care n # 99, 54\%; patient care n # 289, 48\%; x2 # 5.93, P # .11). Respondents providing patient care reported more issues and health challenges with mask wearing than clinicians who did not participate in patient care, including allergies (patient care n # 94, 16\%; no patient care n # 17, 9\%; x2 # 4.3, P # .037), glass fogging (patient care n # 463, 76\%; no patient care n # 113, 62\%; x2 # 14.02, P < .001), headache (patient care n # 232, 38\%; no patient care n # 44, 24\%; x2 # 12.04, P < .001), and skin irritation (patient care n # 337, 55\%; no patient care n # 53, 29\%; x2 # 38.78, P < .001). Clinical staff not providing patient care were more likely to have no issues as compared to those participating in patient care (no patient care n # 34, 19\%; patient care n # 47, 8\%; x2 # 18.26, P < .001). Discussion This study explored the practices and perceptions of face mask use by staff in a pediatric health care system during the COVID-19 pandemic. As a whole, children are not as affected by severe COVID-19-related illness compared to adults, although those with certain underlying conditions may be at higher risk.12 For this reason, many pediatric hos- pitals may not have experienced the same burden that adult hospitals have faced in caring for patients requiring hospi- talization for COVID-19, such as lack of ICU beds, high census, staffing shortages, and lack of morgue capacity. The majority of respondents in our study were nurses who provided direct patient care. This demographic is similar to another study that examined clinical and nonclinical health care worker perceptions of face coverings around the same time pe- riod.13 Alzunitan and colleagues evaluated the differences in Table 4.

FACE MASK USE DURING COVID-19 1100 RESPIRATORY CARE ! JULY 2021 VOL 66 NO 7 perception between face masks and face shields, whereas our study did not inquire about the use of face shields.13 Most respondents in our study indicated they wore a cloth mask outside of the work area and washed their mask after an average of 3 d of use. The CDC recommends wash- ing cloth masks at least daily (https://www.cdc.gov/ coronavirus/2019-ncov/prevent-getting-sick/how-to-wash- cloth-face-coverings.html, Accessed January 19, 2021). Respondents wearing surgical/procedure masks reported replacing their masks after nearly 3 d. Shortages of PPE during the COVID-19 pandemic led to supplies once con- sidered disposable or single-use to be utilized longer or to be reused. Extended use refers to using the same mask with multiple patients without removing, whereas reuse is utili- zation of the same mask for multiple encounters followed by doffing, storage, and donning again.14 In the open-ended responses, several subjects noted concerns and questions regarding safety and efficacy of these PPE practices. The CDC recommends extended use of face masks as part of a contingency capacity strategy and limited reuse with extended use for crisis capacity (https://www.cdc.gov/ coronavirus/2019-ncov/hcp/ppe-strategy/face-maskshtml# contingency-capacity, Accessed December 11, 2020). Contingency capacity involves discarding the mask after removed, at the end of the workday, and if soiled or dam- aged. Hand hygiene is required if the mask is touched. The crisis capacity recommendations include using face masks beyond the manufacturer shelf life, but the maximum num- ber of safe uses is unknown. A systematic review of guid- ance documents for extended use and reuse of PPE concluded the evidence for these practices is limited, and gaps and inconsistencies exist.14 Table 5.

FACE MASK USE DURING COVID-19 RESPIRATORY CARE ! JULY 2021 VOL 66 NO 7 1101 Reprocessing and decontamination of filtering facepiece respirators has become a common practice during the COVID-19 pandemic to conserve PPE. The study institu- tion did offer this service, but it was discontinued after low utilization. The challenges encountered with this approach were that many masks were ineligible for reprocessing if they were stained with makeup, and a minimum number of masks were needed to efficiently use the sterilant, which led to a delay in mask return. Instead, a 5-d quarantine pro- cess was recommended for respirator reuse. The majority of respondents in our study agreed that cor- rectly worn face masks are effective in preventing virus spread and that N95 masks protect staff from contracting COVID-19. More clinical than nonclinical staff agreed that the N95 provides protection from contracting COVID-19. This may be attributed to lack of knowledge by nonclinical staff of how filtering facepiece respirators function. The purpose of universal masking is to decrease virus transmis- sion from infected wearers rather than to provide protec- tion. However, double masking with a cloth mask placed over a medical procedure mask combined with optimal fit to prevent air leakage has been reported to reduce exposure for uninfected wearers in simulated experiments.15 Hand hygiene associated with mask handling was not con- sistent with CDC recommendations across all staff types. Hand hygiene is advised before and after touching the face mask (https://www.cdc.gov/handwashing/when-how- handwashing.html, Accessed January 19, 2021). Subjects reported the most frequent hand hygiene occurred after removing the mask. Clinical staff tended to have more fre- quent hand hygiene with mask handling overall than nonclin- ical staff, which may be a result of their awareness of patient safety initiatives to prevent hospital-acquired infections. Many respondents reported issues or health challenges associated with wearing a face mask. Clinical staff reported more issues than nonclinical staff. This is not surprising as those providing patient care are required to wear a mask at all times, whereas staff working alone in an office may …
