ABSTRACT
Background It is a challenge for pharmacy courses worldwide to combine theoretical knowledge with practical skills to equip students for their future practice. Computer-based simulation offers a way of building a bridge between theory and practice. In recent years, digital simulation has expanded rapidly as a new technique of virtual learning. The digital platform ''Pharmacy Simulator'' proposes computer-based encounters with virtual patients to train clinical and communication skills in a community pharmacy setting. However, during the COVID-19 pandemic, while students were digitally resilient and endured the endless challenges of online lectures, many were dealing with Zoom and screen fatigue. Purpose To investigate pharmacy students' acceptance of Pharmacy Simulator before and during a pandemic situation. This focuses on students' self-assessment and confidence in counselling after playing the scenarios on Pharmacy Simulator. Method Two cohorts of Master of Pharmacy students at The University of Western Australia played two scenarios on Pharmacy Simulator in 2019 (anaphylaxis and salbutamol) and 2021 (anaphylaxis and vaccination). A mixed-method analysis was performed with data from (i) qualitative semi-structured interviews carried out in 2019 pertaining to participants' acceptance of Pharmacy Simulator and in 2021 (ii) a questionnaire with 25 items derived from the interviews. The interviews were transcribed verbatim into electronic format with the data management assistance MAXQDA and analyzed inductively using the Framework Method. Questionnaire responses were analyzed in Microsoft Excel using descriptive statistics. Openended questions were evaluated inductively. Findings Data were collected from 20 interviews and 31 answered questionnaires. In 2019, participants reported that Pharmacy Simulator was a fun, engaging, and straightforward learning tool and, therefore, user-friendly. They reported the feedback at the end of the session to be most valuable. The platform was perceived to fill the gap between the theory from lectures and community pharmacy practice. In 2021, participants ''agreed'' (median: 4, on a 5-point Likert scale) with seven statements about Pharmacy Simulator's usability, such as it being a helpful tool for acquiring new knowledge. Participants' confidence in counselling regarding the scenario topics improved. One participant stated, ''It taught me more through trial and error''. Conclusion Pharmacy students reported similar acceptance levels of Pharmacy Simulator before and during the COVID-19 pandemic. The use of simulation during virtual patient encounters seems to facilitate the transfer from theory to practice, independently of learning conditions that were predominantly screen-based.
ABSTRACT
To combat the ongoing Covid-19 pandemic, many new ways have been proposed on how to automate the process of finding infected people, also called contact tracing. A special focus was put on preserving the privacy of users. Bluetooth Low Energy as base technology has the most promising properties, so this survey focuses on automated contact tracing techniques using Bluetooth Low Energy. We define multiple classes of methods and identify two major groups: systems that rely on a server for finding new infections and systems that distribute this process. Existing approaches are systematically classified regarding security and privacy criteria.Copyright © 2021 ACM.
ABSTRACT
Introduction: Spinal cord and dorsal root ganglion stimulation (SCS and DRG) are standard of care in chronic neuropathic pain. During the COVID-19 pandemic, it was critical to arrange postoperative care. Furthermore, the disparity between travel times and transportation options could influence the decision on seeking healthcare. Lacking financial resources could enhance this issue. Telehealth is usually restricted to video conferences, without interfering with implanted medical devices. Now, there exists a platform for remote programming of those devices. It is accessible via smartphones and allows direct contact between a patient and their doctor. Method(s): We initiated a pilot study for evaluating the performance of remote care in patients with SCS or DRG stimulation. We plan the enrollment of 20 patients, 10 each in the retrospective and the prospective group. Retrospective data has been collected from on-site programmed patients in our outpatient clinic in a large registry study. Prospective data is being collected under the new standard of care in the remotely programmed patients. We assess ten scores and categories to evaluate the status preoperatively, at implantation, and the postoperative course. The postoperative data are assessed in the context of video conferences for remote programming. 12 months after implantation, a final video conference is scheduled. In both groups, the same stimulation systems are used. Result(s): The study is ongoing. In the retrospective group (n=8), the mean duration of the programming appointment including waiting time was 43 minutes and the mean travel time 71 minutes (mean travel distance 106km with corresponding costs). So far, 5 patients have been enrolled for remote programming. Measured with the Telehealth Usability Questionnaire, their overall satisfaction with the system is high. In the Patient Global Impression of Change Scale 6 months after implantation, the retrospective group has a mean of 5 and the prospective group of 6 points. Considering the Visual Analog Scale, there was an improvement in both groups between the baseline and follow-up (in the retrospective group from mean 8 to 5 and in the prospective group from mean 8 to 2). Conclusion(s): The general convenience with the remote programming is high. Compared to the retrospective group, the patients do not experience a lack of efficacy of their stimulation. The use of remote programming offers various advantages, e.g., no travel times nor costs that allow simplified and more frequent programming. Especially in a pandemic or in case of travel limitations it is a very helpful tool.

ABSTRACT
IntroductionEffective communication of COVID-19 information involves clear messaging to ensure that readers comprehend and can easily apply behavioral recommendations. This study evaluated the readability, understandability, and actionability of public health resources produced by the four provincial governments in Atlantic Canada (New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island). MethodsA total of 400 web-based resources were extracted in June 2022 and evaluated using the Flesch-Kincaid Grade Level, CDC Clear Communication Index, and the Patient and Education Materials Assessment Tool. Descriptive statistics and a comparison of mean scores were conducted across provinces and type of resources (e.g., text, video). ResultsOverall, readability of resources across the region exceeded recommendations, requiring an average Grade 11 reading level. Videos and short form communication resources, including infographics, were the most understandable and actionable. Mean scores across provinces differed significantly on each tool;Newfoundland and Labrador produced materials that were most readable, understandable, and actionable, followed by New Brunswick. DiscussionRecommendations on improving clarity of COVID-19 resources are described. Careful consideration in the development of publicly available resources is necessary in supporting COVID-19 knowledge uptake, while reducing the prevalence of misinformation.
ABSTRACT
This paper aims to understand what motivates students at universities in Indonesia to continue using Online Collaborative Tools (OCTs) for their collaboration work. Utilising OCTs is crucial as the COVID-19 pandemic hit us in 2019 and forced all of us, particularly those who studied at university, to work online as precautionary measures. This research employs the Post-Acceptance Model of Information Systems (IS) approach to understand this issue. For an OCT to continue use, performance: effectivity, efficiency, and certainty is the key determinant, and perceived usability: perceived usefulness, perceived ease of use, and perceived enjoyment mediates confirmation and satisfaction and the intention to continue use. A total of 354 participants are involved in the data analysis employing Structural Equation Modelling (SEM). Our results revealed that while the relationship between confirmation and satisfaction is partially mediated by perceived ease of use and enjoyment, the relationship between confirmation and intention to continue use is also partially mediated by perceived usefulness and enjoyment, and satisfaction. We found that the intention to continue using the OCT can be determined by 67.9% (substantial) of the variance of the model. Our research contributes theoretically to the IS research in this context and practically to the OCT discourse. Limitations and future research directions are discussed © 2023, International Journal of Emerging Technologies in Learning.All Rights Reserved.
ABSTRACT
Fully-integrated, component-based CDMS offers flexibility, customization, and efficiency Effective and efficient clinical data collection and management is one of the key factors affecting clinical trial success and is of heightened importance during the COVID-19 pandemic.1 Not only have the scope and complexity of clinical trials continued to increase over the past decade, but the volume and diversity of clinical study data grows ever larger. Researchers have accelerated the development of vaccines and therapeutics for COVID-19 as evidenced by the 4,846 trials found on clinicaltrials. gov.2 The COVID-19 pandemic presents a unique opportunity for understanding technologies that can enable trial data management and their effects on streamlining;and expediting clinical trial design and implementation. Specific measurements evaluated in this study were: database build efficiency, velocity of data collection, frequency of protocol amendments on the database, and the time impact of mid-study updates to the database. [...]the ability to execute mid-study updates or post-go live changes with minimal to no downtime (< one hour) allowed the users and sponsors to work in parallel rather than in serial fashion, speeding up trial start dates and implementation of protocol amendments, and accommodating adaptive COVID-19 trial design.
ABSTRACT
The college entrance examination is vital for program admission. Typically, entrance examinations are conducted onsite using paper and pens. When the COVID-19 pandemic hit, the entrance examination was lifted and physical gatherings were prohibited. Since many schools cannot offer an online admissions exam, they rely on grades and interviews to admit and qualify students for degree programs. However, academic standards differ between schools, and grades may not be enough to assess students' capacity. Thus, this study aims to develop an Online Proctored Entrance Examination System (OPEES) with Degree Program Recommender for colleges and universities to help institutions administer onsite or online entrance tests and generate course suggestions using a rulebased algorithm. The study employed the scrum methodology in software development. OPEES allows applicants to submit applications online, and institutions can manage user accounts, tailor exams and degree programs' criteria, manage exam dates, and assign proctors. Online proctoring using Jitsi, an opensource multiplatform voice, video, and instant messaging tool with end-to-end encryption, ensures exam integrity. The system's features were evaluated by 102 respondents, comprised of end-users (students and school personnel) and IT professionals, using the FURPS (Functionality, Usability, Reliability, Performance, and Supportability) software quality model. In the software evaluation, the overall system proved to be functional as perceived by the respondents, as manifested by the mean rating of 4.61. In conclusion, the system's architecture was deemed feasible and offers a better way to streamline admission examinations and determine a student's applicable degree program by enabling institutions to customize their exams and degree program requirements. It will be beneficial to look into recommendation system algorithms and historical enrollment data to improve the system's use case. © 2022 IEEE.
ABSTRACT
Objectives: To examine patients' telehealth usability during COVID-19 in Dubai. Method(s): A cross-sectional retrospective study adopted Telehealth Usability Questionnaire (TUQ). A total of 64,173 participants who used telehealth services during 2020 - 2021 were recruited from the electronic medical record to participate in electronic survey from October to December 2022. The survey was administered through DHA text messaging system. The survey examined participants' characteristics and the six domains of TUQ with a Likert scale. Frequency, percentage, and weighted mean score percentages were used as descriptive statistics to analyze this data. Result(s): A total of 1,535 participants completed the survey. The overall TUQ showed the mean age of users was 43.37 years (+/-11.67 SD). More than half of the users were females (65.21%), the majority were married (74.46%), of a UAE nationality (83.58%), had higher education (56.68%), and were currently working (57.13%). Consultations and COVID-19-related concerns (45.14%), medication refills (19.80%), and laboratory tests (18.24%) were the main reasons for telehealth visits. Weighted means of TUQ six domains were usefulness (87.11%), ease of use and learnability (86.98%), interface quality (85.73%), interaction quality (86.44%), reliability (79.48%), and satisfaction and future use (86.44%). Conclusion(s): Our study revealed high levels of usability and willingness to use telehealth services as an alternative modality to in-person consultations among the participants of the survey. Our results support the implementation of telehealth services in DHA;however, further studies are required to understand the applicability of telehealth after COVID-19 and how to further improve satisfaction.Copyright © 2023
ABSTRACT
The significance of information and communication technologies in the educational sector in the last few decades has tremendously increased. The current study aims to examine the significance of various individual factors such as teachers' self-concept, self-efficacy and ICT-related subjective self in predicting their perceptions of ICT usability leading to enhance preschool children's learning outcomes. To achieve the study objectives, the authors applied a quantitative research methodology. After surveying 386 preschool teachers in 55 preschools, the data were analyzed using SmartPLS software. Most educational institutions have transformed their traditional modes of education into virtual classrooms. Technological intrusion in the educational sector has increased during COVID-19 and is persistent in the post-COVID era. Similarly, in universities and colleges, the inclusion of digital technologies in preschools has remarkably increased. The current study adds value to the existing body of literature by extending the existing TAM3 to TAM3+ by adding a new domain of subjective self and predicting preschool teachers' ICT usage in the classrooms and the interaction of this usage with technical support to enhance the preschool children's learning outcomes. © 2023 by the author;licensee Asian Online Journal Publishing Group.
ABSTRACT
Background The COVID-19 pandemic has disrupted routine HbA1c testing. This has led to difficulties in monitoring glycaemic control and identifying people with suboptimal glycaemia. Delayed diagnosis of diabetes and suboptimal glycaemic control over extended periods can increase the risk of developing long-term complications of diabetes. The self-collection of capillary blood remotely (at home) for routine HbA1c testing can facilitate monitoring of glycaemic control whilst supporting virtual consultations. The aimof this study was to assess the clinical performance and user acceptance of capillary blood samples prepared remotely using the MiniCollect capillary blood collection device as an alternative to standard venous blood collection for HbA1c analysis. Methods Adult men and women with any type of diabetes were recruited. Following informed written consent, eligible participants provided a venous blood sample at their routine clinic appointment and subsequently prepared a capillary blood sample remotely. Participants also completed a bespoke usability questionnaire. Results Of 84 participants recruited, 62 capillary samples returned to the laboratory, with 41 having a paired venous sample for HbA1c analysis. HbA1c results using both collection methods demonstrated good agreement;Passing-Bablok Regression analysis, y=0 + 1x;R=0.986, Bland-Altman Difference Plot providing a mean difference of 0.3 mmol/mol. Conclusions Over half of participants found the MiniCollect device easy to use. The majority were in favour of the remote capillary blood collection service and would use it if routinely available. The remote self-collection of capillary blood for HbA1c is a convenient alternative for people with diabetes living and working in rural or urban settings ensuring optimal continuance of care.
ABSTRACT
Objective: Acute-phase proteins are a family of proteins synthesized by the liver. With this study, we aimed to investigate the effects of COVID-19 infection on acute phase reactants (AFR) and determine the usability of AFRs as prognostic factors in COVID-19 disease. Material(s) and Method(s): Serum samples taken for routine analysis of the patients admitted to the Emergency Department and diagnosed with COVID-19, were used. AFR levels of 30 patients who resulted in mortality and 30 recovered patients were evaluated. C-reactive protein (CRP), ferritin (FER), ceruloplasmin (Cp), albumin (Alb), prealbumin (Prealb), transferrin (Trf), lactate, Acute Physiology and Chronic Health Evaluation (APACHE), and Sequential Organ Failure Assessment (SOFA) assessment was performed. Result(s): The hazard ratio and 95% confidence interval for FER, CRP, lactate, Alb, Cp, Prealb, Trf, Age, SOFA, and APACHE were 1.001 (1.000-1.001), 1.005 (1.001- 1.008), 1.141 (1.016-1.243), 1.016 (0.740-1.399), 1.016 (0.740-1.399), 1.056 (1.017-1.100), 0.978 (0.917-1.035), 1.000 (0.995-1.006), 1.032 (1.004- 1.064), 1.104 (0.971-1.247), and 1.012 (0.974-1.051), respectively, in univariable model. Only CRP, lactate, and FER found significant in multivariable model. In addition, patients in the nonsurvivors group had significantly higher FER, CRP, lactate, APACHE, age, and SOFA. Nonsurvivors also had lower Alb, Prealb, and serum Trf level compared to survivors. Conclusion(s): CRP, lactate, and FER, which we have shown to be significantly higher in severe COVID-19 patients, will be valuable parameters that will contribute to clinical improvement if they are used in the follow-up of patients due to their easy measurement and predictive values.Copyright © 2023, Nobelmedicus.

ABSTRACT
Introduction: The COVID-19 pandemic posed numerous challenges to patient care, including extensive PPE use, patient care in isolation rooms, inadequate numbers of intensivists particularly in rural communities, use of unfamiliar ventilators that would be partially remedied by the ability to remotely control lung ventilation. The goals of the project were to study the intended use, risk management, usability, cybersecurity for remote control of ventilators and demonstrate the use of a single interface for several different ventilators. Method(s): Clinical scenarios were developed including remote control of the ventilator from an antechamber of an isolation room, nursing station within the same ICU, and remote control from across the country. A risk analysis and was performed and a risk management plan established using the AAMI Consensus Report--Emergency Use Guidance for Remote Control of Medical Devices. A cybersecurity plan is in progress. Testing was done at the MDPNP laboratory. We worked with Nihon Kohden OrangeMed NKV-550, Santa Ana, CA, and Thornhill Medical MOVES SLC, Toronto, Canada. Both companies modified their devices to allow remote control by and application operating on DocBox's Apiary platform. Apiary is a commercially available ICE solution, DocBox Inc, Waltham, MA. An expert panel was created to provide guidance on the design of a single common, simple to use graphical user interface (GUI) for both ventilators. Manufacturers' ventilation modes were mapped to ISO 19223 vocabulary, data was logged using ISO/IEEE 11073-10101 terminology using AAMI 2700-2-1, Medical Devices and Medical Systems - Essential safety and performance requirements for equipment comprising the patient-centric integrated clinical environment (ICE): Part 2-1: Requirements for forensic data logging. Result(s): We demonstrated that both ventilators can be controlled and monitored using common user interface within an institution and across the country. Pressure and flow waveforms were available for the NKV-550 ventilator, and usual ventilator measurements were displayed in near-real time. The interface allowed changing FiO2, ventilation mode, respiratory rate, tidal volume, inspiratory pressure, and alarm settings. At times, increased network latency negatively affected the transmission of waveforms. Conclusion(s): We were able to demonstrate remote control of 2 ventilators with a common user interface. Further work needs to be done on cybersecurity, effects of network perturbations, safety of ventilator remote control, usability implications of having a common UI for different devices needs to be investigated.
ABSTRACT
Remote Patient Monitoring has enjoyed strong growth to new heights driven by several factors, such as the COVID-19 pandemic or advances in technology, allowing consumers and patients to continuously record health data by themselves. This does not come without its challenges, however. A literature review was completed and highlights usability gaps when using wearables or home use medical devices in a virtual environment. Based on these findings, the Pi-CON methodology was applied to close these gaps by utilizing a novel sensor that allows the acquisition of vital signs at a distance, without any sensors touching the patient. Pi-CON stands for passive, continuous and non-contact, and describes the ability to acquire vital signs continuously and passively, with limited user interaction. The preference of vital sign acquisition with a newly developed sensor was tested and compared to vital sign tests taken with patient generated health-data devices (ear thermometer, pulse oximeter) measuring heart rate, respiratory rate and body temperature. In addition, the amount of operator errors and the user interfaces were tested and compared. Results show that participants preferred vital signs acquisition with the novel sensor and the developed user interface of the sensor. Results also revealed that participants had a mean error of .85 per vital sign measurement with the patient-generated health data devices and .33 with the developed sensor, confirming the beneficial impact available when using the developed sensor based on the Pi-CON methodology.
ABSTRACT
As the number of MS Teams, Zoom, and Google Meet users increases with online education, so do the privacy and security vulnerabilities. This study aims to investigate the privacy, security, and usability aspects of few tools that are frequently used for educational purposes by Bangladeshi universities. Consumer security, privacy, and usability are also concerns when it comes to online-based software. This study assesses the most commonly used tools that are used for online education based on three important factors: privacy, security, and usability. Assessment factors concerning the privacy, security, and usability aspects are initially identified. Afterwards, each of the applications was assessed and ranked by comparing their characteristics, functionalities, and terms and conditions (T&C) in contradiction of those factors. In addition, for the purpose of additional validation, a survey was carried out with 57 university students who were enrolled at one of several private universities in Bangladesh. Microsoft Teams, Zoom, and Google Meet have been ranked based on an evaluation of their security, privacy, and usability features, which was accomplished through the use of a knowledge base and a user survey. © 2022 IEEE.
ABSTRACT
Health information exchange (HIE) now exists in diverse forms within and across countries. However, our HIE infrastructure is fragmented, which impedes the ability to meet the needs of varied data sharing use cases—particularly public health data needs that became evident during the COVID-19 pandemic. In response, several efforts—some within the United States and some outside the United States—have started to undertake work to help tie existing HIE approaches together into a more seamless whole. While the societal benefits of doing so are clear, there are substantial cost and complexity involved, leaving it an open question as to how successful they will be. This chapter describes three major efforts underway to advance HIE infrastructure at scale—the Trusted Exchange Framework and Common Agreement (a US policy strategy), the Joint Action Towards the European Health Data Space (an EU initiative), and the emerging concept of health data utility models as more comprehensive repositories of health data with strong government requirements for participation. For each, we describe the effort as well as discuss potential challenges to implementation and success in achieving the intended outcomes. We also discuss a complementary issue related to health data integration and usability of exchanged health information that will become more acute as efforts to advance data sharing at scale are pursued. © 2023 Elsevier Inc.

ABSTRACT
Introduction: Telemedicine in the pandemic of coronavirus disease 2019 (COVID-19) has responded to societal distancing in medical treatments by protecting health workers while also managing available resources. To attain best practices in telemedicine, a platform must be functional, and both patients and clinicians must be satisfied with the technology. To ensure the benefits of telehealth systems, usability refers to how easy the user interfaces of telehealth systems are to use. In this study, the usability of telemedicine systems has been investigated. Material and Methods: The authors of this study review the study from 2015 to 2021 using a combination of the keywords "health", "telemedicine", "telemedicine", "mobile health", "usability" "Software", "System" and "Program", which led to the extraction of 119 articles in this field. Results: Articles in the field of remote health software and evaluation of the usability of remote health applications in the form of applications based on mobile health technologies, web-based applications or a combination of both types with sample devices Primary are wearable electronics, sensors or robots. Conclusion: In this study, most of the remote health software are mobile based and their usability has been evaluated by a questionnaire. Satisfaction is the most important usability attributes to consider when designing Health mobile apps. © 2022, Published by Frontiers in Health Informatics.
ABSTRACT
This case study describes a usability testing course in which students learn by practicing several evaluation methods. The on-campus format makes it possible for teachers and students to meet to discuss recorded test sessions and students can observe other students' execution of pilot studies conducted on campus. The COVID-19 pandemic placed new demands on this course. In-person activities were avoided by some students and many test participants. Some student teams tried remote usability testing. Interestingly, screen recordings (with sound) of the test sessions show that remote testing sometimes helped the students focus more on observation and less on (inappropriately) guiding the test subjects. Another effect was that the students found it easier to recruit participants than during the previous years when the university was teeming with students, lecturers, and non-academic staff. However, the recruited participants were often notably limited to the students' circles of friends. © (2022) by Association for Information Systems (AIS) All rights reserved.
ABSTRACT
Background and Objectives: Virtual reality (VR) applications are increasingly being targeted toward older adults as a means to maintain physical and cognitive skills and to connect with others, especially during the coronavirus disease 2019 era. Our knowledge about how older adults interact with VR is limited, however, since this is an emerging area and the related research literature is still rather slim. The current study focused specifically on older adults' reactions to a social-VR environment, examining participant's views about the possibility of meaningful interactions in this format, the impacts of social-VR immersion on mood and attitude, and features of the VR environment that affected these outcomes. Research Design and Methods: The researchers designed a novel social-VR environment with features intended to prompt conversation and collaborative problem-solving among older adults. Participants were recruited from 3 diverse geographic locations (Tallahassee, FL; Ithaca, NY; and New York City, NY), and were randomly assigned to a partner from one of the other sites for social-VR interaction. The sample consisted of 36 individuals aged 60 and older. Results: Reactions to the social VR were quite positive. Older adults reported high levels of engagement in the environment and perceived the social VR to be enjoyable and usable. Perceived spatial presence was found to be a central driver of positive outcomes. A majority of the participants indicated a willingness to reconnect with their VR partner in the future. The data also identified important areas for improvement that were of concern to older adults, such as the use of more realistic avatars, larger controllers more suited to aging hands, and more time for training/familiarization. Discussion and Implications: Overall, these findings suggest that VR can be an effective format for social engagement among older adults.
ABSTRACT
Background/Aims: The COVID-19 pandemic accelerated the implementation of telehealth and virtual care services. Clinicians must be comfortable using this technology in order for it to be developed effectively and implemented consistently. This study evaluated the influence of various factors, including those theorised in the technology acceptance model, on physicians' intention to use teleconsultations in their clinical practice in Chennai, India. Methods: A snowball sampling method was used to distribute an online survey to physicians in Chennai, India. The survey measured respondents' intention to use teleconsultations (dependent variable), along seven independent variables relating to this technology (perceived usefulness, perceived ease of use, physicians' attitudes, social influences, facilitating conditions, perceived compatibility with the clinical area and trust). A total of 165 responses were collected. Results were analysed using descriptive and correlational statistics, along with multiple linear regression. Results: All seven independent variables were found to be significantly associated with the dependent variable (P<0.01). Multiple linear regression analysis indicated that the independent variables accounted for 67.8% of the variance in respondents' intention to use teleconsultations. Conclusions: Physicians' intention to use teleconsultations is complex and multi-faceted. Although the factors theorised by the technology acceptance model were significantly associated with intention to use telemedicine, other factors were also found to be important, including social influences, external facilitating factors, perceived compatibility with the clinical area and personal trust in technology.
ABSTRACT
Background: COVID-19 testing is critical for identifying cases to prevent transmission. SARS-CoV-2 self-testing has the potential to increase diagnostic testing capacity and to expand access to hard-to-reach areas in low-andmiddle- income countries. We investigated the feasibility and acceptability of COVID-19 self-sampling and self-testing using SARS-CoV-2 Ag-Rapid Diagnostic Tests. Method(s): Between July 2021 to February 2022, we conducted a mixedmethods cross-sectional study examining self-sampling and self-testing using Standard Q and Panbio COVID-19 Ag Rapid Test Device in Urban and rural Blantyre, Malawi. Health care workers and adults (18y+) in the general population were systematically sampled. Result(s): Overall, 1,330 participants were enrolled of whom 674 (56.0%) were female with 664 for self-sampling and 666 for self-testing. Overall mean age was 30.7y (standard deviation [SD] 9.6). Self-sampling usability threshold for Standard Q was 273/333 (82.0%: 95% CI 77.4% to 86.0%) and 261/331 (78.8%: 95% CI 74.1% to 83.1%) for Panbio. Self-testing threshold was 276/335 (82.4%: 95% CI 77.9% to 86.3%) and 300/332 (90.4%: 95% CI 86.7% to 93.3%) for Standard Q and Panbio, respectively. Agreement between self-sample results and professional test results was 325/325 (100%) and 322/322 (100%) for Standard Q and Panbio, respectively. For self-testing, agreement was 332/333 (99.7%: 95% CI 98.3 to 100%) for Standard Q and 330/330 (100%: 95% CI 99.8 to 100%) for Panbio. Odds of achieving self-sampling threshold increased if the participant was recruited from an urban site (odds ratio [OR] 2.15 95% CI 1.44 to 3.23, P < .01. Compared to participants with primary school education those with secondary and those with tertiary achieved higher self-testing threshold OR 1.88 (95% CI 1.17 to 3.01), P = .01 and 4.05 (95% CI 1.20 to13.63), P = .02, respectively. Conclusion(s): One of the first studies to demonstrate high feasibility of self-testing using SARS-CoV-2 Ag-RDTs in low- and middle-income countries potentially supporting large scale-up.
