ABSTRACT

Cerebral small vessel disease (CSVD) is the leading cause of vascular cognitive impairment and is associated with COVID-19. However, contributing factors that often accompany CSVD pathology in COVID-19 patients may influence the incidence of cerebrovascular complications. Thus, a mechanism linking COVID-19 and CSVD has yet to be uncovered and differentiated from age-related comorbidities (i.e., hypertension), and medical interventions during acute infection. We aimed to evaluate CSVD in acute and recovered COVID-19 patients and to differentiate COVID-19-related cerebrovascular pathology from the above-mentioned contributing factors by assessing the localization of microbleeds and ischemic lesions/infarctions in the cerebrum, cerebellum, and brainstem. A systematic search was performed in December 2022 on PubMed, Web of Science, and Embase using a pre-established search criterion related to history of, or active COVID-19 with CSVD pathology in adults. From a pool of 161 studies, 59 met eligibility criteria and were included. Microbleeds and ischemic lesions had a strong predilection for the corpus callosum and subcortical/deep white matter in COVID-19 patients, suggesting a distinct CSVD pathology. These findings have important implications for clinical practice and biomedical research as COVID-19 may independently, and through exacerbation of age-related mechanisms, contribute to increased incidence of CSVD.

ABSTRACT

Macrophages are a first line of defense against pathogens. However, certain invading microbes modify macrophage responses to promote their own survival and growth. Mycobacterium tuberculosis (M.tb) is a human-adapted intracellular pathogen that exploits macrophages as an intracellular niche. It was previously reported that M.tb rapidly activates cAMP Response Element Binding Protein (CREB), a transcription factor that regulates diverse cellular responses in macrophages. However, the mechanism(s) underlying CREB activation and its downstream roles in human macrophage responses to M.tb are largely unknown. Herein we determined that M.tb-induced CREB activation is dependent on signaling through MAPK p38 in human monocyte-derived macrophages (MDMs). Using a CREB-specific inhibitor, we determined that M.tb-induced CREB activation leads to expression of immediate early genes including COX2, MCL-1, CCL8 and c-FOS, as well as inhibition of NF-kB p65 nuclear localization. These early CREB-mediated signaling events predicted that CREB inhibition would lead to enhanced macrophage control of M.tb growth, which we observed over days in culture. CREB inhibition also led to phosphorylation of RIPK3 and MLKL, hallmarks of necroptosis. However, this was unaccompanied by cell death at the time points tested. Instead, bacterial control corresponded with increased colocalization of M.tb with the late endosome/lysosome marker LAMP-1. Increased phagolysosomal fusion detected during CREB inhibition was dependent on RIPK3-induced pMLKL, indicating that M.tb-induced CREB signaling limits phagolysosomal fusion through inhibition of the necroptotic signaling pathway. Altogether, our data show that M.tb induces CREB activation in human macrophages early post-infection to create an environment conducive to bacterial growth. Targeting certain aspects of the CREB-induced signaling pathway may represent an innovative approach for development of host-directed therapeutics to combat TB.

ABSTRACT

Among all RNA viruses, coronavirus RNA transcription is the most complex and involves a process termed "discontinuous transcription" that results in the production of a set of 3'-nested, co-terminal genomic and subgenomic RNAs during infection. While the expression of the classic canonical set of subgenomic RNAs depends on the recognition of a 6- to 7-nt transcription regulatory core sequence (TRS), here, we use deep sequence and metagenomics analysis strategies and show that the coronavirus transcriptome is even more vast and more complex than previously appreciated and involves the production of leader-containing transcripts that have canonical and noncanonical leader-body junctions. Moreover, by ribosome protection and proteomics analyses, we show that both positive- and negative-sense transcripts are translationally active. The data support the hypothesis that the coronavirus proteome is much vaster than previously noted in the literature.

ABSTRACT

PURPOSE: To assess whether transcutaneous retrobulbar amphotericin B injections (TRAMB) reduce exenteration rate without increasing mortality in rhino-orbital-cerebral mucormycosis (ROCM). METHODS: In this retrospective case-control study, 46 patients (51 eyes) with biopsy-proven ROCM were evaluated at 9 tertiary care institutions from 1998 to 2021. Patients were stratified by radiographic evidence of local orbital versus extensive involvement at presentation. Extensive involvement was defined by MRI or CT evidence of abnormal or loss of contrast enhancement of the orbital apex with or without cavernous sinus, bilateral orbital, or intracranial extension. Cases (+TRAMB) received TRAMB as adjunctive therapy while controls (-TRAMB) did not. Patient survival, globe survival, and vision/motility loss were compared between +TRAMB and -TRAMB groups. A generalized linear mixed effects model including demographic and clinical covariates was used to evaluate the impact of TRAMB on orbital exenteration and disease-specific mortality. RESULTS: Among eyes with local orbital involvement, exenteration was significantly lower in the +TRAMB group (1/8) versus -TRAMB (8/14) (p = 0.04). No significant difference in mortality was observed between the ±TRAMB groups. Among eyes with extensive involvement, there was no significant difference in exenteration or mortality rates between the ±TRAMB groups. Across all eyes, the number of TRAMB injections correlated with a statistically significant decreased rate of exenteration (p = 0.048); there was no correlation with mortality. CONCLUSIONS: Patients with ROCM with local orbital involvement treated with adjunctive TRAMB demonstrated a lower exenteration rate and no increased risk of mortality. For extensive involvement, adjunctive TRAMB does not improve or worsen these outcomes.

ABSTRACT

INTRODUCTION: This study aimed to determine adaptations orthodontists made during the coronavirus disease 2019 pandemic to maintain safety and determine which adaptations will remain after the pandemic. METHODS: An original 34-question survey was sent by mail to a randomized selection of practicing orthodontic specialists (n = 1000). Questions included the changes made during the pandemic in 4 categories (infection control, social distancing, appliance type, and teleorthodontics) and whether those changes will remain postpandemic. RESULTS: The use of personal protective equipment increased during the pandemic, with a significant decrease anticipated after the pandemic. The most common aerosol modification during the pandemic and predicted after the pandemic was using an assistant with high-volume suction (61% and 49%, respectively; P = 0.0013). Ninety-six percent of orthodontists changed their waiting room protocol during the pandemic, but only 23% plan to continue that practice (P <0.0001). Forty-two percent of orthodontists increased clear aligners during the pandemic in response to patient demand (91%). The use of teleorthodontics increased from 8% to 68% during the pandemic and is expected to decrease significantly postpandemic. Virtual appointments are anticipated to be used for screening and consultations of new patients and monitoring active patients in clear aligners but not fixed appliances. CONCLUSIONS: The specialty recommended patient safety modifications during the coronavirus disease 2019 pandemic. Postpandemic, enhanced personal protective equipment is expected to decrease, and high-volume suction will likely be continued for aerosol-producing procedures. Teleorthodontics will likely remain in limited use.

ABSTRACT

Purpose To determine adaptations orthodontists made during the COVID-19 pandemic to maintain safety and determine which of these adaptations will remain after the pandemic. Methods An original 34-question survey was sent by mail to a randomized selection of practicing orthodontic specialists (N = 1000). Questions included the changes made during the pandemic in four categories (infection control, social distancing, appliance type, and tele-orthodontics) and whether those changes will remain post-pandemic. Results The use of all forms of personal protective equipment (PPE) increased during the pandemic, with a significant decrease anticipated after the pandemic. The most common aerosol modification during the pandemic and predicted after the pandemic was the use of an assistant with high volume suction (61% and 49% respectively, p=0.0013). Ninety six percent of orthodontists changed their waiting room protocol during the pandemic, but only 23% plan to continue that practice (p<0.0001). Forty-two percent of orthodontists increased clear aligners use during the pandemic in response to patient demand (91%).

Virtual appointments are anticipated to be used for screening and consultations of new patients and monitoring of active patients in clear aligners, but not fixed appliances. Conclusions The specialty utilized recommended modifications for patient safety during the COVID-19 pandemic. Post-pandemic, the use of enhanced PPE is expected to decrease and high-volume suction will likely be continued for aerosol-producing procedures. Tele-orthodontics will likely remain in limited use.

ABSTRACT

The recent high-profile cases of hate crimes in the U.S., especially those targeting Asian Americans, have raised concerns about their risk of victimization. Following the onset of the COVID-19 pandemic, intimations-and even accusations-that the novel coronavirus is an "Asian" or "Chinese" virus have been linked to anti-Asian American hate crime, potentially leaving members of this group not only fearful of being victimized but also at risk for victimization. According to the Stop AAPI Hate Center, nearly 1900 hate crimes against Asian Americans were reported by victims, and around 69% of cases were related to verbal harassment, including being called the "Chinese Coronavirus." Yet, most of the evidence martialed on spikes in anti-Asian American hate crime during the COVID-19 pandemic has been descriptive. Using data from four U.S. cities that have large Asian American populations (New York, San Francisco, Seattle, and Washington D.C.), this study finds that hate crime against Asian Americans increased considerably in 2020 compared with that of 2019. Specifically, hate crime against Asian Americans temporarily surged after March 16, 2020, when the blaming labels including "Kung flu" or "Chinese Virus" were used publicly. However, the significant spike after March 16, 2020, in anti-Asian American hate crime was not sustained over the follow-up time period available for analysis.

ABSTRACT

Away rotations have become a critical factor for a successful orthopaedic surgery residency match. Away rotations significantly improve an applicant's chance of matching into an orthopaedic residency. Away rotations were limited during the 2020 to 2021 academic year because of the COVID-19 pandemic. During the 2021 to 2022 academic year, the American Association of Medical Colleges coalition recommended students only complete 1 rotation outside their home institution, whereas the American Orthopaedic Association Council of Residency Directors argued that multiple rotations should be allowed. We sought to quantify the impact of these restrictions on orthopaedic surgery applicants during the 2020 to 2021 residency application cycle. Methods: An online survey was sent to all applicants applying to the authors' home orthopaedic surgery program. The survey asked respondents to indicate how many away rotations they completed and how many they planned to complete but were unable to complete in the 2020 to 2021 application cycle. Historical match data were obtained from the National Resident Matching Program's publicly accessible Main Residency Match Data and Reports. Results: Survey responses were collected from 650 of 812 applicants (80%) to our program. Over a third of respondents (38.1%) reported completing 3 subinternship rotations during the 2020 to 2021 application cycle. Nearly a quarter of respondents (24.0%) reported completing 4 rotations. Most applicants (50.9%) were unable to complete 5 previously planned rotations because of pandemic-related restrictions, and 25.2% reported an inability to complete 4 rotations. Fewer applicants reported canceling 3 rotations (9.2%), 2 rotations (6.8%), or 1 (7.8%) rotation. Conclusions: Away rotations have been a traditional component of the orthopaedic surgery application process. Restrictions on away rotations in the 2020 to 2021 residency application cycle had affected the number of rotations that applicants were able to complete. However, despite those restrictions, over a third of applicants were able to complete at least 3 rotations. This suggests that the away rotation experience is variable for students and may be multifactorial; however, our study did not investigate the reasons for this. Accordingly, limiting away rotations may support an inequitable environment for medical students applying to orthopaedic surgery, and creating a consensus definition among medical schools, program directors, and orthopaedic chairs of away rotations, their duration, and the maximum number allowed would enhance fairness and reduce inconsistencies.

ABSTRACT

OBJECTIVE: To introduce the Community Resiliency Model (CRM) as mental well-being support for healthcare workers working through the height of the COVID-19 pandemic. DESIGN: Randomised controlled trial with a no treatment control group. SETTING: Two large urban health systems in the Southern United States between October 2020 and June 2021. PARTICIPANTS: Eligible participants were currently employed as healthcare workers within the participating healthcare systems. 275 employees registered and consented electronically in response to email invitations. 253 participants completed the baseline survey necessary to be randomised and included in analyses. INTERVENTION: Participants were assigned 1:1 to the control or intervention group at the time of registration. Intervention participants were then invited to 1-hour virtual CRM class teaching skills to increase somatic awareness in the context of self and other care. MAIN OUTCOME MEASURES: Self-reported data were collected rating somatic awareness, well-being, symptoms of stress, work engagement and interprofessional teamwork. RESULTS: Baseline data on the total sample of 275 (53% nurses) revealed higher symptoms of stress and lower well-being than the general population. The intervention participants who attended a CRM class (56) provided follow-up survey data at 1 week (44) and 3 months (36). Significant improvement for the intervention group at 3 months was reported for the well-being measures (WHO-5, p<0.0087, d=0.66; Warwick-Edinburgh Mental Well-Being Scale, p<0.0004, d=0.66), teamwork measure (p≤0.0002, d=0.41) and stress (Secondary Traumatic Stress Scale, p=0.0058, d=46). CONCLUSION: Baseline results indicate mental health is a concern for healthcare workers. Post intervention findings suggest that CRM is a practical approach to support well-being for healthcare workers during a crisis such as this pandemic. The simple tools that comprise the model can serve as a starting point for or complement self-care strategies to enhance individual resilience and buffer the effects of working in an increasingly stressful work environment.

ABSTRACT

Mask-wearing during the COVID-19 pandemic has prompted a growing interest in the functional impact of masks on speech and communication. Prior work has shown that masks dampen sound, impede visual communication cues, and reduce intelligibility. However, more work is needed to understand how speakers change their speech while wearing a mask and to identify strategies to overcome the impact of wearing a mask. Data were collected from 19 healthy adults during a single in-person session. We investigated the effects of wearing a KN95 mask on speech intelligibility, as judged by two speech-language pathologists, examined speech kinematics and acoustics associated with mask-wearing, and explored KN95 acoustic filtering. We then considered the efficacy of three speaking strategies to improve speech intelligibility: Loud, Clear, and Slow speech. To inform speaker strategy recommendations, we related findings to self-reported speaker effort. Results indicated that healthy speakers could compensate for the presence of a mask and achieve normal speech intelligibility. Additionally, we showed that speaking loudly or clearly-and, to a lesser extent, slowly-improved speech intelligibility. However, using these strategies may require increased physical and cognitive effort and should be used only when necessary. These results can inform recommendations for speakers wearing masks, particularly those with communication disorders (e.g., dysarthria) who may struggle to adapt to a mask but can respond to explicit instructions. Such recommendations may further help non-native speakers and those communicating in a noisy environment or with listeners with hearing loss.

ABSTRACT

The wrath of COVID-19 includes a co-occurring global mental health pandemic, raising the urgency for our health care sector to implement strategies supporting public mental health. In Georgia, a successful nurse-led response to this crisis capitalized on statewide organizations' existing efforts to bolster well-being and reduce trauma. Partnerships were formed and joint aims identified to disseminate a self-care modality, the Community Resiliency Model, to organizations and communities throughout the state.

ABSTRACT

Introduction: Oncohematological patients (OHP) with Covid19 (C19) can develop serious and lethal complications. It depends on underlying disease, chemotherapy (ChT) and immunosuppressor (IS) prescribed. Objectives: compare mortality (M) in OHP vs. hospitalized normal hosts (NH);analyze independent risk factors (IRFs) of M. Methods: 3/2020-5/2022;population: OHP with C19. Prospective, observational data collection. Clinical presentation: NIH scale;Active treatment (AT): IS or ChT;Complete C19 vaccination (CV). Statistics: ANOVA and Tukey's post hoc tests for comparison of groups. Multivariate test to analyze IRFs associated with M. Results: OHP: 62;MM: 19.3%;LLC: 21%;Lymphomas: 24.2%;ALL: 11.3%;AML: 9.7%;MDS: 14.5%. Age: 68 (17-88);Male sex: 77.4%;moderate CAP: 72.6%;Severe CAP: 27.4%;CV: 22.6%;neutropenia (NP): 22.6%;AT: 61.3%. MM was associated with higher M. OD: 5.3 (95% CI 1.1742 -24.1685). OH had higher M statistically significant difference (SSD)- vs. ICP (12/62): 19% vs. (118/1168): 10%;p: 0.02. Multivariate analysis adjusted for age and sex: MM (OR: 5.32, 95% CI: 1.1742-24.1685) and Severe CAP (OD: 11.23, 95% CI: 2.0636 - 61.1310) were IRFs associated with M. AT (OR: 3.2) and NP (OR: 4.18) had higher risk of M with nonSSD;CV (OR: 0.66 95% CI 0.1110-4.0235) had lower risk without SSD. Conclusions: MM and severe CAP were IRFs for M. CAP was associated with higher M in OHP than NH. CV could be a protective factor without SSD. The high M documented in OHP with C19 justifies implementation of early preventive measures and treatment in this population.

ABSTRACT

Purpose This paper investigated the impact of COVID-19 stay-at-home regulations on the spatial distribution of commercial burglary in San Francisco. Method Geocoded commercial burglary data for 2003–2021 from San Francisco were analyzed using the Andresen Spatial Point Pattern Test to examine potential spatial movement in commercial burglary. Results Concentrations of commercial burglary spatially shifted following the emergence of COVID-19 and the subsequent stay-at-home orders. Original hot spots experienced a relative decrease in commercial burglary, and crime spread out throughout the city. These spatial changes in commercial burglary appear to be related to variations in guardianship and criminal opportunity. Conclusion These findings suggest that the dramatic shifts in routine activities resulting from the COVID-19 policies could disrupt spatial burglary patterns, especially burglary clustering. Law enforcement should consider the spatial dynamics of commercial burglary, as well as land use heterogeneity, to effectively respond to crime during periods of social distancing and business shutdowns.

ABSTRACT

Epstein-Barr virus (EBV) hepatitis is well established, and most cases involves asymptomatic liver enzyme abnormalities. Albeit rare, viruses such as EBV have been reported to induce generalized pustular psoriasis (GPP);and exanthems such as GPP have been associated with acute hepatitis. This case describes a unique case of cholestatic hepatitis due to EBV, followed by a diffuse pustular rash suggestive of GPP. After complete resolution of the cholestatic hepatitis, the patient returned over a year later with concurrent hepatitis and diffuse pustular rash. Case: An obese 26 year-old African-American female presented to the hospital on three separate occasions over a 15 month span with slightly varying symptoms. At the index hospitalization she presented with fatigue and jaundice. Liver chemistries revlead a mixed pattern liver injury, see Table 1. Extensive serological evaluation was unremarkable, though antinuclear antibody and anti-smooth muscle antibody were mildly and non-specifically elevated, but IgG was normal. A liver biopsy was performed revealing portal and lobular inflammation with predominantly lymphocytic moderate micro-vesicular steatosis (Figure 1). EBV PCR returned positive at 20,737 IU/mL yielding a diagnoses of EBV-induced hepatitis. She returned to the hospital one week later due to a diffuse pruritic and painful rash. She had scleral icterus and diffuse erythematous plaques with tiny pustules dispersed over the body sparing the palms, soles, and mucosal surfaces. Laboratory values were overall improved as noted in Table 1. Punch biopsy of the right arm was suggestive of EBV induced GPP. She rapidly stabilized and was discharged the following day with triamcinolone 0.1% ointment. The patient had an uneventful convalescence and liver chemistries returned to normal. Approximately 15 months after her initial hospitalization, she presented with both recurrent hepatitis and a pustular, pruritic, erythematous rash with perioral and periorbital swelling. She denied taking any new medications or supplements. Labs revealed recurrent, though now primarily cholestatic liver injury, see Table 1. Results of a repeat thorough serological evaluation were negative, including for EBV-PCR and COVID-19. Abdominal ultrasound revealed a 16 cm hepatic length. Pustules, spongiosis, and edema were found on repeat skin biopsy, suggestive of GPP. She recovered quickly with systemic steroids. Awareness of GPP induced hepatitis can guide a judicious assessment of abnormal liver chemistries. Furthermore, unnecessary healthcare utilization can be avoided by providing appropriate and timely pharmacotherapy (i.e., corticosteroid taper) for on demand flares.

ABSTRACT

(1) Background: As an emerging topic, no known study to date has described interviews with US dentists regarding their experiences during the beginning of the coronavirus disease 2019 (COVID-19) with regard to office closures and their implications for both the dentists and the patients they serve, especially among dentists in their first decade of work and new to practice ownership roles. Therefore, the purpose of this study was to describe the experiences of early-career US dentists during the initial stages of the COVID-19 pandemic. (2) Methods: This study utilized a semi-structured interview protocol and employed qualitative descriptive methodology. SPSS 26 and NVivo12 were utilized for data analysis. (3) Results: In April 2020, a total of 12 early-career US dentists completed the interview study protocol. The study sample majority was male (67%), with a mean age of 32 (range = 30–37) and an average of 6 years of dental practice experience (range = 5–10). Participants completed phone interviews with the research team. In summary, three organizing themes emerged: (1) Dentistry during COVID-19: Experiences during the first wave, (2) Long-term concerns regarding COVID-19, and (3) COVID-19 professional communication and dental research. (4) Conclusions: The chief findings of this study are dentists' long-term concerns for the profession post-COVID-19. Research must still determine how to best prepare for future infectious disease outbreaks with regards to safeguarding the health of the dental workforce and maintaining the oral health of patient populations.

ABSTRACT

BACKGROUND: Thrombosis in COVID-19 worsens mortality. In our study, we sought to investigate how the dose and type of anticoagulation (AC) can influence patient outcomes. METHODS: This is a single-center retrospective analysis of critically ill intubated patients with COVID-19, comparing low-molecular-weight heparin (LMWH) and unfractionated heparin (UFH) at therapeutic and prophylactic doses. Of 218 patients, 135 received LMWH (70 prophylactic, 65 therapeutic) and 83 UFH (11 prophylactic, 72 therapeutic). The primary outcome was mortality. Secondary outcomes were thromboembolic complications confirmed on imaging and major bleeding complications. Cox proportional-hazards regression models were used to determine whether the type and dose of AC were independent predictors of survival. We performed Kaplan-Meier survival analysis to compare the cumulative survivals. RESULTS: Overall, therapeutic AC, with either LMWH (65% vs 79%, P = .09) or UFH (32% vs 46%, P = .73), conveyed no survival benefit over prophylactic AC. UFH was associated with a higher mortality rate than LMWH (66% vs 28%, P = .001), which was also evident in the multivariable analysis (LMWH vs UFH mortality, hazard ratio: 0.47, P = .001) and in the Kaplan-Meier survival analysis. Thrombotic and bleeding complications did not depend on the AC type (prophylactic LMWH vs UFH: thrombosis P = .49, bleeding P = .075; therapeutic LMWH vs UFH: thrombosis P = .5, bleeding P = .17). When comparing prophylactic with therapeutic AC, the rate of both thrombotic and bleeding complications was higher with the use of LMWH compared with UFH. In addition, transfusion requirements were significantly higher with both therapeutic LMWH and UFH. CONCLUSIONS: Among intubated critically ill COVID-19 intensive care unit patients, therapeutic AC, with either LMWH or UFH, conveyed no survival benefit over prophylactic AC. AC with LMWH was associated with higher cumulative survival compared with AC with UFH.

ABSTRACT

PURPOSE: Gabapentin is a widely prescribed analgesic with increased popularity over recent years. Previous studies have characterized use of gabapentin in the outpatient setting, but minimal data exist for its initiation in the inpatient setting. The objective of this study was to characterize the prescribing patterns of gabapentin when it was initiated in the inpatient setting. METHODS: This was a retrospective cohort study of a random sample of adult patients who received new-start gabapentin during hospital admission. Patients for whom gabapentin was prescribed as a home medication, with one-time, on-call, or as-needed orders, or who died during hospital admission were excluded. The primary outcome was characterization of the gabapentin indication; secondary outcomes included the starting and discharge doses, the number of dose titrations, the rate of concomitant opioid prescribing, and pain clinic follow-up. Patients were stratified by surgical vs nonsurgical status. RESULTS: A total of 464 patients were included, 283 (61.0%) of whom were surgical and 181 (39.0%) of whom were nonsurgical. The cohort was 60% male with a mean (SD) age of 56 (18) years; surgical patients were younger and included more women. The most common indications for surgical patients were multimodal analgesia (161; 56.9%), postoperative pain (53; 18.7%), and neuropathic pain (26; 9.2%), while those for nonsurgical patients were neuropathic pain (72; 39.8%) and multimodal analgesia (53; 29.3%). The mean starting dose was similar between the subgroups (613 mg for surgical patients vs 560 mg for nonsurgical patients; P = 0.196). A total of 51.6% vs 81.8% of patients received gabapentin at discharge (P < 0.0001), while referral/follow-up to a pain clinic was minimal and similar between the subgroups (1.1% vs 3.9%; P = 0.210). CONCLUSION: Inpatients were commonly initiated on gabapentin for generalized indications, with approximately half discharged on gabapentin. Further studies are needed to assess the impact of this prescribing on chronic utilization.

ABSTRACT

Cardiac surgery continues to evolve. The last year has been notable for many reasons. The guidelines for coronary revascularization introduced significant discord. The pandemic continues to affect the care on a global scale. Advances in organ procurement and dissection care move forward with better understanding and better technology.

ABSTRACT

OBJECTIVES: This study aimed to compare the costs incurred and saved from universal use of N95 respirators with surgical masks for operating room providers in the United States during the COVID-19 pandemic. METHODS: We built a decision analytic model to compare direct medical costs of healthcare workers (HCWs) infected with COVID-19 during operating room procedures from expected transmission when using an N95 respirator relative to a surgical mask. We also examined quarantine costs. RESULTS: Results varied depending upon prevalence and false-negative rates of tests, but if N95 respirators reduce transmission by 2.8%, prevalence is at 1%, and testing yields 20% false negatives, providers should be willing to pay an additional $0.64 per HCW for the additional protection. Under this scenario, approximately 11 COVID-19 cases would be averted among HCWs per day. CONCLUSIONS: Potential savings depend on disease prevalence, rate of asymptomatic patients with COVID-19, accuracy of testing, the marginal cost of respirators, and the quarantine period. We provide a range of calculations to show under which conditions N95 respirators are cost saving.
