Prevalence, Causes, and Adverse Clinical Impact of Delayed Presentation of Non-COVID-19-Related Emergencies during the COVID-19 Pandemic: Findings from a Multicenter Observational Study.

OBJECTIVE: The coronavirus disease (COVID-19) pandemic has disrupted healthcare systems worldwide, resulting in decreased and delayed hospital visits of patients with non-COVID-19-related acute emergencies. We evaluated the impact of the COVID-19 pandemic on the presentation and outcomes of patients with non-COVID-19-related medical and surgical emergencies. METHOD: All non-COVID-19-related patients hospitalized through emergency departments in three tertiary care hospitals in Saudi Arabia and Bahrain in June and July 2020 were enrolled and categorized into delayed and non-delayed groups (presentation ≥/=24 or <24 h after onset of symptom). Primary outcome was the prevalence and cause of delayed presentation; secondary outcomes included comparative 28-day clinical outcomes (i.e., 28-day mortality, intensive care unit (ICU) admission, invasive mechanical ventilation, and acute surgical interventions). Mean, median, and IQR were used to calculate the primary outcomes and inferential statistics including chi-square/Fisher exact test, t-test where appropriate were used for comparisons. Stepwise multivariate regression analysis was performed to identify the factors associated with delay in seeking medical attention. RESULTS: In total, 24,129 patients visited emergency departments during the study period, compared to 48,734 patients in the year 2019. Of the 256 hospitalized patients with non-COVID-19-related diagnoses, 134 (52%) had delayed presentation. Fear of COVID-19 and curfew-related restrictions represented 46 (34%) and 25 (19%) of the reasons for delay. The 28-day mortality rates were significantly higher among delayed patients vs. non-delayed patients (n = 14, 10.4% vs. n = 3, 2.5%, OR: 4.628 (CI: 1.296-16.520), p = 0.038). CONCLUSION: More than half of hospitalized patients with non-COVID-19-related diagnoses had delayed presentation to the ED where mortality was found to be significantly higher in this group. Fear of COVID-19 and curfew restrictions were the main reasons for delaying hospital visit.

Sensitivity and Specificity of Rapid SARS-CoV-2 Antigen Detection Using Different Sampling Methods: A Clinical Unicentral Study.

Rapid antigen detection of SARS-CoV-2 has been widely used. However, there is no consensus on the best sampling method. This study aimed to determine the level of agreement between SARS-CoV-2 fluorescent detection and a real-time reverse-transcriptase polymerase chain reaction (rRT-PCR), using different swab methods. Fifty COVID-19 and twenty-six healthy patients were confirmed via rRT-PCR, and each patient was sampled via four swab methods: oropharyngeal (O), nasal (N), spit saliva (S), and combined O/N/S swabs. Each swab was analyzed using an immunofluorescent Quidel system. The combined O/N/S swab provided the highest sensitivity (86%; Kappa = 0.8), followed by nasal (76%; Kappa = 0.68), whereas the saliva revealed the lowest sensitivity (66%; kappa = 0.57). Further, when considering positive detection in any of the O, N, and S samples, excellent agreements with rRT-PCR were achieved (Kappa = 0.91 and 0.97, respectively). Finally, among multiple factors, only patient age revealed a significant negative association with antigenic detection in the saliva. It is concluded that immunofluorescent detection of SARS-CoV-2 antigen is a reliable method for rapid diagnosis under circumstances where at least two swabs, one nasal and one oropharyngeal, are analyzed. Alternatively, a single combined O/N/S swab would improve the sensitivity in contrast to each site swabbed alone.

COVID-19 Myth Busters: Comparing knowledge and perceptions amongst the dental workforce at an institution in the Eastern Province, Saudi Arabia.

BACKGROUND: Currently, world is suffering from a respiratory disease names as COVID-19. This is a novel coronavirus (n-CoV), a new strain which has not been previously identified in humans and it has spread in more than 100 locations internationally due to which it is termed as "public health emergency of international concern" (PHEIC) by the World Health Organization So far, no study done as yet to assess whether the dental workforce is aware about the facts and myths related to Covid-19 awareness. OBJECTIVE: This study aims to analyze and compare the level of awareness about the facts and myths related to COVID-19 amongst faculty, dental students and prep year students of the College of Dentistry (COD) as part of an awareness campaign. METHODS: An awareness test about COVID-19 was designed using information from the World Health Organization's (WHO) Myth Busters Awareness webpage. The questionnaire was administrated online to faculty and students, of the College of Dentistry and preparatory year students who had applied for the admission to the dental college using a secure enterprise online assessment platform (Blackboard). The tests were administered over a period of three months from March to June 2020. A written informed consent was obtained. RESULTS: The online COVID-19 awareness test was administered to 810 participants, out of which 325 (40%) were prep year students, 429(53%%) were dental students, and 56 (7%) were faculty members. Analysis of the results showed that 86% of the Faculty were able to correctly identify the facts and the myths related to COVID-19 followed by 81% of the prep year students and 74% of the dental students. Preparatory year student's knowledge related to COVID-19 was found to be high when compared to dental students (26.47±4.27, 23.67±6.2). Student to faculty knowledge score did not differ significantly (p = 0.808). CONCLUSION: This study reports about a successful pilot test conducted to assess the perceived knowledge about facts and myths related to corona virus amongst the dental workforce.

High-Flow Nasal Cannula Treatment in Patients with COVID-19 Acute Hypoxemic Respiratory Failure: A Prospective Cohort Study.

BACKGROUND: Early use of high-flow nasal cannula (HFNC) decreases the need for endotracheal intubation (EI) in different respiratory failure causes. While HFNC is used in coronavirus disease 2019 (COVID-19)-related acute hypoxemic respiratory failure (AHRF) under weak recommendations, its efficacy remains to be investigated. OBJECTIVES: The primary objective was to examine HFNC efficacy in preventing EI among COVID-19 patients with AHRF. Secondary objectives were to determine predictors of HFNC success/failure, mortality rate, and length of hospital and intensive care unit (ICU) stay. PATIENTS AND METHODS: This is a prospective cohort study conducted at a single tertiary care centre in Saudi Arabia from April to August 2020. Adult patients admitted to the ICU with AHRF secondary to COVID-19 pneumonia and managed with HFNC were included. We excluded patients who were intubated or managed with non-invasive ventilation before HFNC. RESULTS: Forty-four patients received HFNC for a median duration of 3 days (interquartile range, 1-5 days). The mean age was 57 ± 14 years, and 86% were men. HFNC failure and EI occurred in 29 (66%) patients. Patients in whom HNFC treatment failed had a higher risk of death (52% versus 0%; P = 0.001). After adjusting for confounding factors, a high SOFA score and a low ROX index were significantly associated with HFNC failure (hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.04-1.93; P = 0.025; and HR, 0.61; 95% CI, 0.42-0.88; P = 0.008, respectively). CONCLUSIONS: One-third of hypoxemic COVID-19 patients who received HFNC did not require intubation. High SOFA score and low ROX index were associated with HFNC failure.

Dental Fear and Patient Preference for Emergency Dental Treatment Among Adults in COVID-19 Quarantine Centers in Dammam, Saudi Arabia.

PURPOSE: Dental fear is associated with the avoidance of dental visits and negative oral health outcomes. It is important to assess distribution of dental fear and preference for emergency dental treatment among adult population during COVID-19. Therefore, the purpose of this study was to evaluate dental fear and emergency dental treatment among adults in COVID-19 quarantine centers in Greater Dammam, Saudi Arabia. MATERIALS AND METHODS: Male and female adults (N=606) in quarantine centers for COVID-19 participated in this cross-sectional study (June-July 2020). Dental Fear Survey was used to collect data on dental fear. The participants also provided their responses about emergency dental treatment/dental attendance patterns in addition to demographic information. RESULTS: The mean DFS score of the sample was 39.08 ± 19.47, and 23.1% of the participants were a little fearful and 22.6% were highly fearful. About 36.8% reported that they would prefer to visit a dental office in case of dental emergency mostly for dental pain and fractured tooth during the COVID-19 pandemic. Only 10.4% of the participants reported visiting a dentist in less than 3 months, 35.8% in less than 6 months, 52.5% between 6 and 12 months and more, and 1.3% never visited the dentist. DFS scores significantly differed among participants who visited the dentist in less than 3 months (31.86 ± 14.57), less than 6 months (37.70 ± 18.57), between 6 and 12 months and more (40.78 ± 20.23), and never visited the dentist (65.75 ± 14.74) (P < 0.001). The timing of last dental visit (P < 0.001), female gender (P 0.039), and dental pain (P < 0.001) were the significant predictors of dental fear. CONCLUSION: Dental fear was common among adults with a predilection for the female gender. Increased dental fear was significantly related to dental pain and reduced dental attendance. Only one-third of adults were willing to perform emergency dental visits.

COVID-19 outbreak, disruption of dental education, and the role of teledentistry

ABSTRACT The novel coronavirus disease 2019 (COVID-19) has affected the whole world and has now been declared a Pandemic by the World Health Organization (WHO). Although the mortality rate of this virus is low, it is especially potent against people with underlying systemic conditions. Dentistry is a profession where the doctor, as well as the dental staff, works in close vicinity to the patient's mouth. Dental education has two core components;didactic and clinical training (including patient care). Dental education has been interrupted in the past due to certain events (Arab Spring and SARS outbreak). Currently, the pandemic of COVID-19 has disrupted dental education globally as most of the dental schools and universities in the world have closed amidst the COVID-19 outbreak. Teledentistry is a subspecialty of telemedicine that helps in the provision of educational activities, advice, and diagnosis about treatment over a distance with the help of technology like video conferencing. The current overview summarizes the potential role of teledentistry in continuing the dental educational process in terms of delivery of didactic components, clinical training, and patient care. It can be concluded that with modern updated devices and tools, teledentistry can be an effective way to prevent disruption of dental education and it can be utilized in continuing the dental educational process in this critical time of the COVID-19 outbreak.

Current Clinical Dental Practice Guidelines and the Financial Impact of COVID-19 on Dental Care Providers.

The novel coronavirus disease 2019 (COVID-19) has been acknowledged as a pandemic by the World Health Organization (WHO). The aim of this study was to review guidelines issued by different health regulatory bodies amid the COVID-19 outbreak and financial constraints faced by dentists globally. Relevant papers and news articles were identified in Google Scholar and PubMed. The search was made using the keywords "COVID-19," "COVID-19 and dentistry," and "the financial impact of COVID-19 on dentistry." Studies and news articles published in languages other than English were excluded and a final selection of 53 relevant studies, guideline documents, and news articles were made. The outbreak of COVID-19 has affected all businesses including general dental practices, which are suffering huge financial losses as they have been advised to provide only emergency dental care. These recommendations should be appreciated as a positive step but they have caused serious financial implications for dental practices. It can be concluded that current dental practice globally is limited to the provision of emergency treatments only. This step is appreciative, but has resulted in huge financial losses sustained by dental care providers (DCPs) worldwide. The governments and health regulatory bodies of developed countries are trying to help dental practices to evolve from this troublesome situation, but there is no visible policy from the underdeveloped world that could help the DCPs to save their practices from closing down due to the financial constraints.

Dental Facilities During the New Corona Outbreak: A SWOT Analysis.

Recently, there have been many global outbreaks of diseases. The latest is the coronavirus disease of 2019 (COVID-19) pandemic. The virus has spread worldwide and is transmitted mainly through droplets or by touching contaminated surfaces. Globally, healthcare systems are challenged due to a lack of workplace safety and professional obligations in addition to the rapid spread of the virus. Dental facilities are at greater risk due to the nature of dental care. The aim of this review study was to provide a situational analysis within dental facilities during the new COVID-19 outbreak. Published papers concerning dental facilities and COVID-19 were retrieved from PubMed, search engines, and organizational websites. All data were reviewed, arranged into themes, and then categorized either as strengths or weaknesses with respect to addressing the COVID-19 pandemic in dental facilities, and accordingly, threats and possible opportunities to the handling of the pandemic were identified. Preparedness of dental facilities during the current pandemic is a weakness that needs to be addressed promptly. Shortage of dental care providers, cyber security, economic losses, and ethical challenges are possible threats due to the current outbreak. Coordination and prompt communication among all healthcare providers during such outbreaks is a strength that needs to be supported. This strengths, weaknesses, opportunities, and threats (SWOT) analysis can be a useful tool for guiding decision-making as it is crucial during the current pandemic to work on weaknesses, avoid threats, and utilize all future opportunities.
