Clear communication around surgical device use is crucial to patient safety. We evaluated the utility of the Device Briefing Tool (DBT) as an adjunct to the Surgical Safety Checklist.A nonrandomized, controlled pilot of the DBT was conducted with surgical teams at an academic referral center. Intervention departments used the DBT in all cases involving a surgical device for 10 wk. Utility, relative advantage, and implementation effectiveness were evaluated via surveys. Trained observers assessed adherence and team performance using the Oxford NOTECHS system.Of 113 individuals surveyed, 91 responded. Most respondents rated the DBT as moderately to extremely useful. Utility was greatest for complex devices (89%) and new devices (88%). Advantages included insight into the team's familiarity with devices (70%) and improved teamwork and communication (68%). Users found it unrealistic to review all device instructional materials (54%). Free text responses suggested that the DBT heightened awareness of deficiencies in device familiarity and training but lacked a clear mechanism to correct them. DBT adherence was 82%. NOTECHS scores in intervention departments improved over the course of the study but did not significantly differ from comparator departments.The DBT was rated highly by both surgeons and nurses. Adherence was high and we found no evidence of "checklist fatigue." Centers interested in implementing the DBT should focus on devices that are complex or new to any surgical team member. Guidance for correcting deficiencies identified by the DBT will be provided in future iterations of the tool.

The WHO Surgical Safety Checklist is a communication tool designed to improve surgical safety processes and enhance teamwork. It has been widely adopted since its introduction over ten years ago. As surgical safety needs evolve, organizations should periodically review and update their checklists. A holistic evaluation of the checklist in the context of an organization is the first step to making informed updates. In this article, we describe a comprehensive but feasible strategy for checklist evaluation which we developed and implemented as part of a surgical safety initiative in a high-performing center.A three-part evaluation plan was developed and carried out by a multidisciplinary team. The evaluation included assessment of 1. Quality of care through a review of surgical safety events; 2. Safety culture through a validated survey and informal feedback; and 3. Checklist performance through direct observations and a staff survey. To prepare for re-implementation the current institutional checklist was critically evaluated and a context assessment survey was administered to surgical staff.The evaluation revealed challenges in communication and teamwork, with surgical staff often perceived to be working in silos. The quality of care assessment indicated room for improvement in safety processes. Deficiencies in the safety culture measures of communication and feedback shed light on an overall lack of engagement with the checklist. Checklist performance demonstrated good adherence to the items on the checklist but limited engagement by the surgical team and minimal communication between subteams. These findings informed our revisions to the checklist and its implementation processes.We developed and implemented a comprehensive, scalable approach to checklist evaluation which directly informed improvements to the checklist that were tailored to the organization's current context. Organizations can apply this framework to breathe new life into their checklist and transform their safety culture.

Nurses' burnout and psychological well-being are a significant concern during the pandemic.The aim of this study is to (i) examine the level of burnout, anxiety, depression, perceived stress and self-rated health for nurses at two time-points, 2020 and 2021, and (ii) examine the socio-demographic characteristics, work-related factors and perceived workplace support factors in relation to the level of burnout.This is a cross-sectional study with a longitudinal approach. A convenience sample of registered nurses who worked in an acute care tertiary hospital in Singapore were surveyed during two time-points. Participants' health, socio-demographic characteristics, work-related factors and perceived workplace support factors were collected.Among the 179 nurses, there was a significant increase in burnout level, poorer self-rated health and reduced job dedication. A decrease in the percentage of nurses who felt appreciated at work was reported in 2021 (p = 0.04). Nurses who felt their team was not working well together were 3.30 times more likely to experience burnout (95% CI 1.12 to 9.69; p = 0.03). Nurses who reported that they never felt appreciated by their department/hospital were 8.84 times more likely to experience burnout (95% CI 2.67 to 29.21; p 0.001). Nurses with poorer self-rated health were more likely to report burnout (95% CI: 1.32-6.03; p = 0.008).Nurses had an increased experience of burnout, reduced job dedication and poorer self-rated health after the outbreak.Interventions at the departmental and organizational levels are needed to improve the workplace support. Strategies to support nurses' psychological well-being during the aftermath of COVID-19 are vital to managing nurses' burnout and improving job dedication and self-rated health.

Surgical devices are implicated in approximately 15% of intraoperative interruptions and 25% of errors. Device-related interruptions (DRIs) are therefore an important target for surgical quality improvement, but scalable measurement methodologies are lacking. The researchers therefore developed, pilot tested, and refined a simple tool for assessing intraoperative DRIs.Five DRI categories achieved face validity with frontline providers and surgical safety experts: improper/challenging assembly, device failure, loss of sterility, disconnection, and absent/wrong device. A data collection tool was created based on these categories as well as a free-text section to capture emergent DRI categories. After a brief training session, the tool was pilot tested by observers at a large academic referral center.In a sample of 210 operations, observers noted 66 DRIs across 39 cases. DRIs were most common in colorectal (38.0 per 100 cases), gynecologic (33.3 per 100 cases), and hepatopancreatobiliary surgery (32.1 per 100 cases). Device failure accounted for 30.3% of observed DRIs. Three emergent categories were identified: user unfamiliarity with the device (15.2%), video display malfunction (4.5%), and physical breakage of the device (1.5%).Measurement of DRIs by novice observers is a feasible and scalable approach to support quality improvement efforts focusing on surgical devices. This approach could provide actionable insights to improve device safety, such as informing educational and training programs, optimizing surgical tray composition, and improving the physical layout of the operating room.

Background Large-scale quarantine facilities staffed with non-healthcare workers (NHCW) were instrumental in preventing community spread of COVID-19 (coronavirus disease of 2019). The objective of this study was to determine the effectiveness of a newly developed procedural skills training framework in ensuring personal protective equipment (PPE) compliance of PPE-naïve NHCWs. Materials and methods We developed a PPE procedural skills training framework for NHCWs using the Learn, See, Practice, Prove, Do, and Maintain (LSPPDM) framework and international guidelines on PPE for healthcare workers. The NHCWs underwent PPE training using this framework, conducted by a team of Infection Prevention nurses, prior to being stationed within the CCF. Effectiveness of the LSPPDM PPE training framework was assessed using: 1) competency assessment scores for NHCWs, 2) PPE compliance rates from daily audit findings, and, 3) healthcare-associated COVID-19 infection rates of NHCWs. Results A total of 883 NHCWs had completed the PPE training and demonstrated competency in PPE compliance, fulfilling 100% of the checklist requirements. Mean PPE compliance of all NHCWs during the 11-week study period was noted to be >96%. The post-implementation improvement was statistically significant when the compliance was expressed in 3-days blocks) and in bed management staff (P = < 0.05). None of the 883 NHCWs who underwent PPE training via the LSPPDM framework were diagnosed with healthcare-associated COVID-19 infection. Conclusions An evidence-based skills training framework is effective in PPE training of large numbers of NHCWs, resulting in high compliance of appropriate PPE use and prevention of healthcare-associated COVID-19 infection.

OBJECTIVES The COVID-19 pandemic has forced a creative transition to virtual platforms due to physical distancing and travel restrictions. We designed and tested a highly scalable virtual training curriculum for novice raters using the Oxford NOTECHS non-technical skills rating system. DESIGN A three-day training course comprising virtual didactics, virtually facilitated simulations, and independent live observations was implemented. NOTECHS scores were submitted for eleven standardized video simulations and four live operations. Intraclass correlation coefficients (ICCs) were calculated for total NOTECHS scores and subcomponent scores. Raters previously trained in-person with the same standardized videos served as a comparator group for equivalence testing. SETTING All study activities were conducted in a large academic tertiary referral center in Singapore as part of an ongoing surgical safety initiative. PARTICIPANTS Seven staff members underwent training (three virtually and four in-person). None had prior surgical experience or non-technical skills assessment training. RESULTS ICCs for total NOTECHS scores were 0.85 (95% CI, 0.73-0.98) for virtually trained raters and 0.83 for those trained in-person (95% CI, 0.68-0.99). Scores were equivalent between groups within a 10% margin. CONCLUSIONS Non-technical skills assessment can be reliably taught in a highly scalable virtual format. Virtual NOTECHS training is a valuable tool for educational and quality improvement initiatives during the COVID-19 pandemic and for centers that lack ready access to onsite non-technical skills training expertise.

ObjectivesThe majority of the cancelled elective surgeries caused by the COVID-19 pandemic globally were estimated to occur in low- and middle-income countries (LMICs), where surgical services had long been in short supply even before the pandemic. Therefore, minimising disruption to existing surgical care in LMICs is of crucial importance during a pandemic. This study aimed to explore contributory factors to the continuity of surgical care in LMICs in the face of a pandemic.DesignSemistructured interviews were conducted over zoom with surgical leaders of 25 tertiary hospitals from 11 LMICs in South and Southeast Asia in September to October 2020. Key themes were subsequently identified from the interview transcripts using the Braun and Clarke’s method of thematic analysis.ResultsThe COVID-19 pandemic affected all surgical services of participating institutions to varying degrees. Overall, elective surgeries suffered the gravest disruption, followed by outpatient surgical care, and finally emergency surgeries. Keeping healthcare workers safe and striving for continuity of essential surgical care emerged as notable response strategies observed across all participating institutions.ConclusionThis study suggested that four factors are important for the resilience of surgical care against COVID-19: adequate COVID-19 testing capacity and effective institutional infection control measures, designated COVID-19 treatment facilities, whole-system approach to balancing pandemic response and meeting essential surgical needs, and active community engagement. These findings can inform healthcare institutions in other countries, especially LMICs, in their effort to tread a fine line between preserving healthcare capacity for pandemic response and protecting surgical services against pandemic disruption.

Purpose We aim to study the prevalence of olfactory and taste dysfunction (OTD) in subjects residing in a Community Care Facility (CCF), a center unique to Singapore that is dedicated to isolate foreign workers with COVID-19 infection who have mild disease with minimal or no symptoms. Methods This is a cross-sectional study analyzing data prospectively collected from COVID-19-positive subjects who were admitted into a single-center Singapore EXPO CCF from 1st May 2020 to 1st July 2020. The following variables were collected: age, gender, ethnicity, anosmia, ageusia and acute respiratory infection (ARI) symptoms. Symptoms of anosmia and ageusia were self-declared via a mandatory questionnaire administered on admission. Results A total of 1983 subjects were included. The overall prevalence of anosmia and ageusia is 3.0% and 2.6%, respectively. 58% of anosmic subjects have co-existent ageusia and 72.6% of anosmic subjects have no concurrent sinonasal symptoms. OTD is less likely to present in subjects who are asymptomatic for ARI, compared to those symptomatic for ARI (anosmia: 2.0% versus 4.4% p = 0.002; ageusia: 1.6% versus 4.2% p

During the coronavirus disease 2019 (COVID-19) pandemic, Singapore implemented large-scale institutional isolation facilities to contain outbreaks among migrant workers who contracted COVID-19 but did not have the ability to self-isolate. In this article, the authors share their experience operating one of the largest of these facilities., Singapore is one of the most densely populated small island–states in the world. During the coronavirus disease 2019 (COVID-19) pandemic, Singapore implemented large-scale institutional isolation units called Community Care Facilities (CCFs) to combat the outbreak in the community by housing low-risk COVID-19 patients from April to August 2020. The CCFs were created rapidly by converting existing public spaces and used a protocolized system, augmented by telemedicine to enable a low health care worker–patient ratio (98 health care workers for 3200 beds), to operate these unique facilities. In the first month, a total of 3758 patients were admitted to 4 halls, 4929 in-house medical consults occurred, 136 patients were transferred to a hospital, 1 patient died 2 weeks after discharge, and no health care workers became infected. This article shares the authors' experience in operating these massive-scale isolation facilities while prioritizing safety for all and ensuring holistic patient care in the face of a public health crisis and lean health care resources.

Objectives: This study examined the prevalence of anxiety, depression, and job burnout among frontline healthcare workers (HCWs) across six Southeast Asian countries (Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam) during the COVID-19 pandemic in 2021. We also inves-tigated the associated risk and protective factors. Methods: Frontline HCWs (N = 1381) from the participating countries participated between 4 January and 14 June 2021. The participants completed self-reported surveys on anxiety (GAD-7), depression (PHQ-8), and job burnout (PWLS). Multivariate logistic regressions were performed with anxiety, depression, and job burnout as outcomes and sociodemographic and job characteristics and HCW perceptions as predictors. Results: The average proportion of HCWs reporting moderate anxiety, moderately severe depression, and job burnout across all countries were 10%, 4%, and 20%, respectively. Working longer hours than usual (Odds ratio [OR] = 1.82; 3.51), perceived high job risk (1.98; 2.22), and inadequate personal protective equipment (1.89; 2.11) were associated with increased odds of anxiety and job burnout while working night shifts was associated with increased risk of depression (3.23). Perceived good teamwork was associated with lower odds of anxiety (0.46), depression (0.43), and job burnout (0.39). Conclusion: Job burnout remains a foremost issue among HCWs. Potential opportunities to improve HCW wellness are discussed. publishedVersion

Objective: Breast cancer is the most common cancer in women across all ethnicities, accounting for almost one in three incident cancers in female, and the leading cause of mortality in Singapore. Literature reveals that survivors of breast cancer have many concerns, and these concerns can linger on for decades. The primary aim of this secondary analysis was to establish the concerns of breast cancer survivors and use the data to inform practice. Methods: The present report was part of a bigger data designed to evaluate the concerns of cancer survivors (top six cancers) across the survivorship trajectory. Data of 438 breast cancer survivors were derived from a cross-sectional survey of the self-reported concerns of 1107 cancer survivors, using the questionnaire adopted from the Mayo Clinic Cancer Centre's Cancer Survivors Survey of Needs. Logistic regression models were fitted to estimate the odds ratios to assess the association of various variables with the presence of ≥1 concerned or very concerned issue among patients. Linear regression models were fitted to identify the variables associated with quality of life (QOL). Results: A total of 438 breast cancer survivors responded to this survey. The top five concerns were cancer treatment and recurrence risk (55.5%), followed by fear of recurrence (FOR) (54.6%), long-term effects of treatment (53.4%), osteoporosis/bone health (39.0%), and keeping primary care physicians informed (37.4%). Cancer treatment and recurrence risk, FOR, and long-term treatment effects were among the top concerns across the survivorship trajectory. The mean QOL was 7.5 on a scale of 0–10. Conclusions: Irrespective of the cancer trajectory, survivors of breast cancer have serious concerns that warrant attention. Designing patient care delivery that addresses these concerns identified is critical in assisting them in their coping process and enhancing their QOL.

Highlights • The eACS service described provides 24/7 coverage of trauma, acute general surgery and critical care. • There were no patient/staff cross infections of COVID-19. • The eACS service reduced length of stay, mortality and costs to the organisation. • Staff felt the service prioritised their safety from COVID-19., Background As the COVID-19 pandemic sweeps across the world, healthcare departments must adapt to meet the challenges of service provision and staff/patient protection. Unlike elective surgery, acute care surgery (ACS) workloads cannot be artificially reduced providing a unique challenge for administrators to balance healthcare resources between the COVID-19 surge and regular patient admissions. Methods An enhanced ACS (eACS) model of care is described with the aim of limiting COVID-19 healthcare worker and patient cross-infection as well as providing 24/7 management of emergency general surgical (GS) and trauma patients. The eACS service comprised 5 independent teams covering a rolling 1:5 24-hr call. Attempts to completely separate eACS teams and patients from the elective side were made. The service was compared to the existing ACS service in terms of clinical and efficiency outcomes. Finally, a survey of staff attitudes towards these changes, concerns regarding COVID-19 and psychological well-being was assessed. Results There were no staff/patient COVID-19 cross-infections. Compared to the ACS service, eACS patients had reduced overall length of stay (2-days), time spent in the Emergency Room (46 min) and time from surgery to discharge (2.4-hours). The eACS model of care saved financial resources and bed-days for the organisation. The changes were well received by team-members who also felt that their safety was prioritised. Conclusion In healthcare systems not overwhelmed by COVID-19, an eACS model may assist in preserving psychological well-being for healthcare staff whilst providing 24/7 care for emergency GS and trauma patients.

Objectives/hypothesis Our study aimed to review the impact of preoperative radiotherapy (RT) and other factors on the lymph node count of neck dissection (ND) specimens from patients with head and neck cancer (HNC). A retrospective study was conducted on all patients with head and neck cancers who had undergone NDs in Singapore General Hospital between 1992 and 2013. Study design Retrospective study. Methods Patients were categorized into two groups: patients treated with RT with or without chemotherapy before ND and patients who had undergone ND surgery without previous history of RT. The primary endpoint for this study would be the lymph node count from ND. Results The study cohort consists of 1,024 NDs on 829 patients. There were 597 (58.3%) radical/modified radical NDs involving levels I-V. Within this group, 75 (12.6%) NDs had preoperative RT. Preoperative RT and age were found to significantly reduce nodal yield in both univariate and multivariate analysis in the radical/modified radical ND subgroup. In our multivariate analysis, preoperative RT was shown to decrease the nodal yield by 7.464 (P = .0002, 95% confidence interval [CI]: -11.35 to -3.58). Advanced age independently decreases nodal yield, even after accounting for the effect of RT (P = .0002, 95% CI: -0.27 to -0.08). In addition, preoperative RT has a more pronounced effect in reducing lymph node count in the older age group. Conclusions Preoperative RT and advanced age are independent and synergistic factors that reduce nodal count from NDs in patients with head and neck cancers. Level of evidence 4 Laryngoscope, 130: 1947-1953, 2020.

Background Multidisciplinary team meetings or tumor boards (TBs) form a pivotal component of oncology practice. The crux of a TB revolves around making treatment decisions based on succinct head and neck cancer (HNC) patient data presentations, which can be challenging and complex. Apart from meticulous TB presentations, discussions and treatment plan documentation is equally important. The aim of this study was to structure an electronic synoptic TB data presentation to address all these areas. The overarching benefits of systematic TB data collection include facilitating audits and research. Methods We utilized a secure web‐based tool that was used for common scientific research purposes but customized to store HNC patient data. The data points were tabulated across eight TB pages: (a) TB scheduling, (b) patient biodata, (c) diagnosis details, (d) index presentation, (e) images, (f) management and histopathology, (g) TB presentation, and (h) TB discussion and decisions. Each data point leads to additional fields by branching logic to permit further relevant data entry. This was integrated within the patient electronic medical records allowing for a direct internal trajectory to recall TB data. Results From October 2015 to October 2018, we recorded over 2000 presentations for 1279 individual patients. This is a quality improvement initiative, and hence, the results are more of a broad analysis of our TB presentation process. The most common cancers were squamous cell (523, 41%), thyroid (207, 16%), and nasopharyngeal (139, 11%) carcinomas. Importantly, this system has formed the basis for a number of clinical and translational research projects and audit outcomes. Conclusion Despite TBs being vital to oncologic practice, little attempt has been made to report TB data management. In this study, we present an efficient system that permits the integration of dual functions: TB data presentation and oncologic data collection for research, recall, and audit purposes.

A successful public health response during the COVID-19 pandemic pivots on the ability of health care workers (HCWs) to work through immense workplace-related physical and psychological pressures.The aim of current study was to explore support needs of HCWs during the COVID-19 outbreak in Singapore and to identify implications for practice and workplace policies.A descriptive qualitative approach was adopted in this study. HCWs from a major public health care cluster in Singapore (n = 612) responded to an open-ended question in an online survey. Results were analyzed using content analysis via an inductive approach.Five main themes that borrows from Maslow's Hierarchy of Needs emerged from content analysis, with 17 categories under the themes. The 5 main themes are: physical needs, safety needs, love and belonging needs, esteem needs and self-actualization needs.Findings from this study indicate that there were many unmet needs among HCWs during the COVID-19 pandemic. An overview of various need areas identified in this study may guide future research and development of interventions to mitigate the negative impact of disease outbreaks on HCWs.

Background Non-technical skills are critical to surgical safety. We examined the impact of the COVID-19 pandemic on non-technical skills of operating room (OR) teams in Singapore. Materials and methods Observers rated live operations using the Oxford NOTECHS system. Pre- and post-COVID observations were captured from November 2019 to January 2020 and from January 2021 to February 2021, respectively. Scores were compared using Schuirmann's Two One-Sided Test procedure. Multivariable linear regression was used to adjust for case mix. A 10% margin of equivalence was set a priori. Results Observers rated 159 cases: 75 pre-COVID and 84 post-COVID. There were significant differences between groups in surgical department and surgeon-reported case complexity (both P

Introduction: We investigated knowledge, attitudes, and practice (KAP) about COVID-19 and related preventive measures in Singaporeans aged > 60 years. Methods: This was a population-based, cross-sectional, mixed-methods study (13 May 2020–9 June 2020) of participants aged >60 years. Self-reported KAP about ten COVID-19 symptoms and six government-endorsed preventive measures were evaluated. Multivariable regression models identified sociodemographic and health-related factors associated with knowledge, attitudes and practices in our sample. Associations between knowledge/attitude scores, and practice categories were determined using logistic regression. 78 participants were interviewed qualitatively about practice of additional preventive measures and data were analysed thematically. Results: Mean awareness score of the symptoms was 7.2/10. Fever (93.0%) and diarrhoea (33.5%) were the most- and least-known symptoms, respectively. Most knew all six preventive measures (90.4%), perceived them as effective (78.7%), and practiced ‘wear a mask’ (97.2%). Indians, Malays, and those in smaller housing had poorer mean knowledge of COVID-19 symptoms scores. Older participants had poorer attitudes towards preventive measures. Compared to Chinese, Indians had lower odds of practicing 3/6 recommendations. A one-point increase in knowledge of and attitudes towards preventive measures score had higher odds of always practicing 3/6 and 2/6 measures, respectively. Qualitative interviews revealed use of other preventive measures, e.g. maintaining a healthy lifestyle. Conclusions: Elderly Singaporeans displayed high levels of KAP about COVID-19 and related preventive measures, with a positive association between levels of knowledge/attitude, and practice. However, important ethnic and socioeconomic disparities were evident, suggesting key vulnerabilities remain, requiring immediate attention.

Objective To develop a 2-stage discrete events simulation (DES) based framework for the evaluation of elective surgery cancellation strategies and resumption scenarios across multiple operational outcomes. Materials and Methods Study data was derived from the data warehouse and domain knowledge on the operational process of the largest tertiary hospital in Singapore. 34,025 unique cases over 43 operating rooms (ORs) and 18 surgical disciplines performed from 1 January 2019 to 31 May 2020 were extracted for the study. A clustering approach was used in stage 1 of the modelling framework to develop the groups of surgeries that followed distinctive postponement patterns. These clusters were then used as inputs for stage 2 where the DES model was used to evaluate alternative phased resumption strategies considering the outcomes of OR utilization, waiting times to surgeries and the time to clear the backlogs. Results The tool enabled us to understand the elective postponement patterns during the COVID-19 partial lockdown period, and evaluate the best phased resumption strategy. Differences in the performance measures were evaluated based on 95% confidence intervals. The results indicate that two of the gradual phased resumption strategies provided lower peak OR and bed utilizations but required a longer time to return to BAU levels. Minimum peak bed demands could also be reduced by approximately 14 beds daily with the gradual resumption strategy, whilst the maximum peak bed demands by approximately 8.2 beds. Peak OR utilization could be reduced to 92% for gradual resumption as compared to a minimum peak of 94.2% with the full resumption strategy. Conclusions The 2-stage modelling framework coupled with a user-friendly visualization interface were key enablers for understanding the elective surgery postponement patterns during a partial lockdown phase. The DES model enabled the identification and evaluation of optimal phased resumption policies across multiple important operational outcome measures. Lay abstract During the height of the COVID-19 pandemic, most healthcare systems suspended their non-urgent elective surgery services. This strategy was undertaken as a means to expand surge capacity, through the preservation of structural resources (such as operating theaters, ICU beds, and ventilators), consumables (such as personal protective equipment and medications), and critical healthcare manpower. As a result, some patients had less-essential surgeries postponed due to the pandemic. As the first wave of the pandemic waned, there was an urgent need to quickly develop optimal strategies for the resumption of these surgeries. We developed a 2-stage discrete events simulation (DES) framework based on 34,025 unique cases over 43 operating rooms (ORs) and 18 surgical disciplines performed from 1 January 2019 to 31 May 2020 captured in the Singapore General Hospital (SGH) enterprise data warehouse. The outcomes evaluated were OR utilization, waiting times to surgeries and time to clear the backlogs. A user-friendly visualization interface was developed to enable decision makers to determine the most promising surgery resumption strategy across these outcomes. Hospitals globally can make use of the modelling framework to adapt to their own surgical systems to evaluate strategies for postponement and resumption of elective surgeries.

Ultrasonic or bipolar radiofrequency energy devices are routinely used for dissection and hemostasis during thyroidectomy. We report a single-center, prospective, randomized controlled trial comparing the utility and outcomes of Harmonic Focus, an ultrasonic coagulating shear device (UCSD), versus Ligasure Small Jaw, an electrothermal bipolar vessel sealer (EBVS) in thyroidectomy (NCT01765686). Between December 2012 to January 2016, eligible patients were randomized to undergo hemithyroidectomy using either a UCSD or an EBVS. The primary outcome was duration of surgery. Secondary outcomes included blood loss, postoperative complications, ease of device use, ease of device set-up, vocal cord function, postoperative wound drainage, pain score, and adverse events. Of 110 patients assessed for eligibility, 100 were randomly allocated (UCSD: 49 patients; EBVS: 51 patients) and analyzed by intention-to-treat. There were no differences in specimen delivery time, total duration of surgery, wound drainage, and adverse events between the two groups. The UCSD group had a greater proportion of patients with higher postoperative pain scores in the first 72 h (8.1% vs. 2.0%, p = 0.043). Surgeons reported greater ease of use for the UCSD (49% vs. 27%; p = 0.005), while operating room staff favored the EBVS (60% vs. 33%, p = 0.005). Energy devices are equally effective in reducing thyroidectomy operative times, with no differences in the duration of surgery, drainage, or adverse events. Use of the UCSD was associated with higher postoperative pain scores, but was favored by the surgeons, likely due to the ability to perform fine dissection with the device itself.

Background The Operating Theatre (OT) is the largest cost centre as well as the main revenue generator in most hospitals. One of the common problems affecting optimal OT utilization is the cancellation of scheduled surgeries. The goal of this study was to identify factors associated with cancellation within 24 h of scheduled surgeries in a tertiary hospital. Methods All elective surgeries performed on adults 18 years and above between June 2015 and December 2016 were included. Cancellations ≤24 h from the scheduled start time of the surgery were recorded, with their reasons for cancellation. Data relating to the patient, surgeon and planned surgery were obtained from the hospital operational database. Univariate analysis and multivariable analysis were conducted using logistic regression. Results A total of 4060 scheduled surgeries were included, of which 398 (9.8%) were cancelled within 24 h of surgery. On multivariate analysis, cancellation within 24 h of surgery was associated with history of heart failure (Adjusted odds ratio, AOR1.65; 95%CI 1.08–2.50), advanced chronic kidney disease (AOR2.33; 95%CI 1.58–3.39), or a history of hip fracture (AOR2.29; 95%CI 1.33–3.80), low socio-economic status (on Medifund financing, AOR3.16; 95%CI 1.37–6.72), history of ≥4 cancelled surgeries in the past 3 years (AOR2.38; 95%CI 1.30–4.19), and scheduled time in the afternoon (AOR1.83; 95%CI 1.44–2.32) and evening (AOR2.09; 95%CI0.73–5.13), compared to the morning. Attendance at preoperative anaesthesia assessment clinic was associated with reduced likelihood of cancellation (AOR0.55; 95%CI0.43–0.72). Conclusions Several patient and system factors can be used to identify scheduled surgeries that are at high likelihood of cancellation within 24 h of surgery, which may inform strategies to improve the efficiency of OT utilization, including having a dedicated preoperative anaesthesia assessment clinic.

Ameloblastoma is a rare tumor of odontogenic epithelium, the low incidence rate of which precludes statistical determination of its molecular characterizations. Despite recent genomic and transcriptomic profiling, the etiology of ameloblastomas remains poorly understood. Risk factors of ameloblastoma development are also largely unknown. Whole exome sequencing was performed on 11 mandibular ameloblastoma samples. We identified 2 convergent mutational signatures in ameloblastoma: 1) a signature found in multiple types of lung cancers with probable etiology of tobacco carcinogens (COSMIC signature 4) and 2) a signature present in gingivobuccal oral squamous cell carcinoma and correlated with tobacco-chewing habits (COSMIC signature 29). These mutational signatures highlight tobacco usage or related mutagens as one possible risk factor of ameloblastoma, since the association of BRAF mutations and smoking was demonstrated in multiple studies. In addition to BRAF hotspot mutations (V600E), we observed clear inter- and intratumor heterogeneities. Interestingly, prior to BRAF mutation, important genes regulating odontogenesis mutated (e.g., corepressor BCOR), possibly playing important roles in tumorigenesis. Furthermore, recurrent mutations in the CDC73 gene, the germline mutations of which predispose patients to the development of jaw tumors, were found in 2 patients, which may lead to recurrence if not targeted by therapeutic drugs. Our unbiased profiling of coding regions of ameloblastoma genomes provides insights to the possible etiology of mandibular ameloblastoma and highlights potential disease risk factors for screening and prevention, especially for Asian patients. Because of the limited sample size and incomplete habitual, dietary, and occupational data, a causal link between tobacco usage and ameloblastoma still requires further investigations.

The scheduling of operating room (OR) slots requires the accurate prediction of surgery duration. We evaluated the performance of existing Moving Average (MA) based estimates with novel machine learning (ML)-based models of surgery durations across two sites in the US and Singapore. We used the Duke Protected Analytics Computing Environment (PACE) to facilitate data-sharing and big data analytics across the US and Singapore. Data from all colorectal surgery patients between 1 January 2012 and 31 December 2017 in Singapore and, 1 January 2015 to 31 December 2019 in the US were used, and 7585 cases and 3597 single and multiple procedure cases from Singapore and US were included. The ML models were based on categorical gradient boosting (CatBoost) models trained on common data fields shared by both institutions. The procedure codes were based on the Table of Surgical Procedure (TOSP) (Singapore) and the Current Procedural Terminology (CPT) codes (US). The two types of codes were mapped by surgical experts. The CPT codes were then transformed into the relative value unit (RVU). The ML models outperformed the baseline MA models. The MA, scheduled durations and procedure codes were found to have higher loadings as compared to surgeon factors. We further demonstrated the use of the Duke PACE in facilitating data-sharing and big data analytics.

There are no well-defined treatment recommendations for elderly patients with advanced head and neck squamous cell carcinoma. This study aimed to investigate whether aggressive treatment among the elderly translated into better survival outcomes.Retrospective cohort study.Single tertiary institution.Elderly patients (≥60 years) with advanced-stage head and neck squamous cell carcinoma (stage III and IV) treated between January 1991 and May 2014 were reviewed. According to current National Comprehensive Cancer Network guidelines, they were classified to have received standard or substandard treatment. Overall survival (OS), locoregional recurrence-free survival, and distant recurrence-free survival were evaluated.A total of 355 patients were treated curatively: 194 with up-front surgery and 161 with radiotherapy or concurrent chemotherapy and radiotherapy. Median OS was higher among patients who received standard treatment (42.0 vs 16.0 months, P.001). On multivariate analysis, standard treatment showed superior OS ( P.001). Use of substandard treatment showed a hazard ratio of 2.09 (95% CI, 1.59-2.74) for poorer OS.Aggressive standard treatment protocols should be advocated for elderly patients, where comorbidities permit, as they confer better outcomes.

Background Haemorrhoids is a common chronic disease that can significantly impact patients’ quality of life. Yet, few studies have evaluated health-related quality of life (HRQoL) of patients with haemorrhoids before and after treatment. This study investigated the HRQoL of patients with haemorrhoids before and after treatment and the change in HRQoL from baseline. Methods A prospective observational study of patients with haemorrhoids was conducted at two public hospitals in Kandy, Sri Lanka. Two questionnaires assessing symptom severity and haemorrhoid-specific QoL were administered at initial consultation and at 4- and 8-week follow-ups after treatment (sclerotherapy, rubber band ligation (RBL), haemorrhoidectomy or evacuation of haematoma). The primary outcome was the least squares (LS) change of HRQoL score from baseline, measured using the Short Health Scale adapted for Haemorrhoidal Disease (4 domains: symptom load, interference with daily activities, concern, general well-being). Results In 48 patients selected for this study, LS mean change from baseline showed significant improvement in HRQoL across all domains and total Short Health Scale adapted for Haemorrhoidal Disease score at 4- and 8-week follow-ups (P Conclusion Patients with haemorrhoids had improved HRQoL after invasive treatment. Haemorrhoid-specific QoL is an important component of the extent of disease and can serve as an aid to guide treatment, assess outcomes and monitor disease.

Objective This study assessed the improvement in Quality of Life (QoL) of Chronic Venous Disease (CVD) patients in Sri Lanka following treatment. Methods This was a prospective observational study of 58 newly or previously diagnosed CVD patients. QoL was assessed by the 14-item ChronIc Venous dIsease quality of life Questionnaire (CIVIQ-14) at 4 and 8 weeks after treatment. Results At 8 weeks, the improvement in Global score from baseline was greatest in the surgical group with adjusted least squares mean of 23.5 (p Conclusion Both surgical and non-surgical treatments improved QoL of CVD patients.

Importance Three-dimensionally printed nasopharyngeal swabs (3DP swabs) have been used to mitigate swab shortages during the coronavirus disease 2019 (COVID-19) pandemic. Clinical validation for diagnostic accuracy and consistency, as well as patient acceptability, is crucial to evaluate the swab’s performance. Objective To determine the accuracy and acceptability of the 3DP swab for identifying severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Design, Setting, and Participants A diagnostic study was conducted from May to July 2020 at 2 tertiary care centers in Singapore with different reference swabs (FLOQSwab [COPAN Diagnostics] or Dacron swab [Deltalab]) and swab processing techniques (wet or dry) to evaluate the performance of the 3DP swab compared with traditional, standard-of-care nasopharyngeal swabs used in health care institutions. The participants were patients with COVID-19 in the first 2 weeks of illness and controls with acute respiratory illness with negative test results for SARS-CoV-2. Paired nasopharyngeal swabs were obtained from the same nostril and tested for SARS-CoV-2 by reverse-transcriptase polymerase chain reaction. The sequence of swabs was randomized based on odd and even participant numbers. Main Outcomes and Measures Primary outcome measures were overall agreement (OA), positive percentage agreement (PPA), and negative percentage agreement of the 3DP swab compared with reference swabs. Secondary outcome measures were the correlation of cycle threshold (Ct) values of both swabs. Results The mean (SD) age of participants was 45.4 (13.1) years, and most participants were men (87 of 89 [97.8%]), in keeping with the epidemiology of the COVID-19 pandemic in Singapore. A total of 79 patients with COVID-19 and 10 controls were recruited. Among the patients with COVID-19, the overall agreement and PPA of the 3DP swab was 91.1% and 93.5%, respectively, compared with reference swabs. The PPA was 100% for patients with COVID-19 who were tested within the first week of illness. All controls tested negative. The reverse-transcriptase polymerase chain reaction Ct values for theORF1abandE-genetargets showed a strong correlation (intraclass correlations coefficient, 0.869-0.920) between the 3DP and reference swab on independent testing at each institution despite differences in sample processing. Discordant results for both gene targets were observed only at high Ct values. Conclusions and Relevance In this diagnostic study of 79 patients with COVID-19 and 10 controls, the 3DP swab performed accurately and consistently across health care institutions and could help mitigate strained resources in the escalating COVID-19 pandemic.

UNSTRUCTURED • Background The COVID-19 pandemic unmasked how quickly healthcare systems could be overwhelmed. One of the most pressing issues was the lack of hospital and intensive care beds. Attempts to mitigate these addresses both ends of the equation: admissions and bed creation. While it is relatively straightforward to utilize resources in generating more facilities, we were in unchartered waters with regards to refining triage criteria for admission to hospital for patients in the setting of community primary care. • Methods This narrative review shares our journey in determination and revision of triage criteria and effecting a robust self-monitored and reported automated vital sign system in a cohort of 7578 COVID-19 patients managed out-of-hospital. • Results: We present descriptive statistics on our patient cohort’s vital signs, compliance rate to monitoring, percentage of patients triggering medical review, percentage of patients transferred out to hospital and adverse events incidence. • Conclusions: We believe there are lessons and potential applications for the international community from our experience.

PURPOSE:We present the strategy of a comprehensive cancer center organized to make operations pandemic proof and achieve continuity of cancer care during the COVID-19 pandemic.METHODS:Disease Outbreak Response (DORS) measures implemented at our center and its satellite clinics included strict infection prevention, manpower preservation, prudent resource allocation, and adaptation of standard-of-care treatments. Critical day-to-day clinical operations, number of persons screened before entry, staff temperature monitoring, and personal protection equipment stockpile were reviewed as a dashboard at daily DORS taskforce huddles. Polymerase chain reaction swab tests performed for patients and staff who met defined criteria for testing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection were tracked. Descriptive statistics of outpatient attendances and treatment caseloads from February 3 to May 23, 2020, were compared with the corresponding period in 2019.RESULTS:We performed COVID-19 swabs for 80 patients and 93 staff, detecting three cancer patients with community-acquired COVID-19 infections with no nosocomial transmission. Patients who required chemotherapy, radiotherapy, or surgery and patients who are on maintenance treatment continued to receive timely treatment without disruption. The number of intravenous chemotherapy treatments was maintained at 97.8% compared with 2019, whereas that of weekly radiotherapy treatments remained stable since December 2019. All cancer-related surgeries proceeded without delay, with a 0.3% increase in workload. Surveillance follow-ups were conducted via teleconsultation, accounting for a 30.7% decrease in total face-to-face clinic consultations.CONCLUSION:Through the coordinated efforts of a DORS taskforce, it is possible to avoid nosocomial SARS-CoV-2 transmissions among patients and staff without compromising on care delivery at a national cancer center.
