Importance: During COVID-19, Singapore simultaneously experienced a dengue outbreak, and acute hospitals were under pressure to lower bed occupancy rates. This led to new models of care to treat patients with acute, low-severity medical conditions either at home, in a hospital-at-home (HaH) model, or in a clinic-style setting sited at the emergency department in an ambulatory care team (ACT) model, but a reliable cost analysis for these models is lacking., Objective: To compare personnel costs of HaH and ACT with inpatient care., Design, Setting, and Participants: In this economic evaluation study, time-driven activity-based costing was used to compare the personnel cost of inpatient care with treating dengue via HaH and treating chest pain via ACT. Participants were patients with nonsevere dengue and chest pain unrelated to a coronary event admitted via the emergency department to the internal medicine service of a tertiary hospital in Singapore., Exposures: HaH for dengue and ACT for chest pain., Main Outcomes and Measures: A process map was created for the patient journey for a typical patient with each condition. The amount of time personnel spent on delivering care was estimated and the cost per minute determined based on their wages in 2022. The total cost of care was calculated by multiplying the time spent by the per-minute cost of the personnel resource and summing all costs., Results: Compared with inpatient care, HaH used 50% less nursing time (418 minutes, 95% uncertainty interval [UI], 370 to 465 minutes) but 80% more medical time (303 minutes, 95% UI, 270 to 338 minutes) per case of dengue. If implemented nationally, HaH would save an estimated 56 828 SGD per year (95% UI, -169 497 to 281 412 SGD [US $41 856; 95% UI, -$124 839 to $207 268]). The probability that HaH is cost saving was 69.2%. Compared with inpatient care, ACT used 15% less nursing time (296 minutes, 95% UI, 257 to 335 minutes) and 50% less medical time (57 minutes, 95% UI, 46 to 69 minutes) per case of chest pain. If implemented nationally, ACT would save an estimated 1 561 185 SGD per year (95% UI, 1 040 666 to 2 086 518 SGD [US $1 149 862; 95% UI, $766 483 to $1 536 786]). The probability that ACT is cost saving was 100%., Conclusions and Relevance: This economic evaluation found that the HaH and ACT models decreased the overall personnel cost of care. Reorganizing hospital resources may help hospitals reap the benefits of reduced hospital-acquired infections, improved patient recovery, and reduced hospital bed occupancy rates.

Introduction: Exertional rhabdomyolysis (ER) is caused by myocyte breakdown after strenuous physical activity. In recent years, the incidence of spin-induced ER (SER) has been increasing. We describe the clinical characteristics, management and outcomes of patients admitted for SER., Method: A review was conducted for all patients admitted to Singapore General Hospital for SER from 1 March 2021 to 31 March 2022. All patients with the admission diagnosis of "rhabdomyolysis", "raised creatine kinase (CK) level", or "elevated CK level" with a preceding history of spin-related physical exertion were included. Patients without a history of exertion, with a history of non-spin related exertion, or with a peak serum CK <1000 U/L were excluded., Results: There were 93 patients in our final analysis; mean age was 28.6±5.6 years and 66 (71.0%) were female patients. Mean body mass index was 25.0±5.7 kg/m 2 ; 81 (87.1%) patients were first-time spin participants. All patients had muscle pain, 68 (73.1%) had dark urine, 16 (17.2%) muscle swelling and 14 (15.1%) muscle weakness. There were 80 (86.0%) patients with admission CK of >20,000 U/L. Mean admission creatinine was 59.6±15.6 μmol/L. Mean intravenous (IV) hydration received was 2201±496 mL/ day, oral hydration 1217±634 mL/day and total hydration 3417±854 mL/day. There was 1 (1.1%) patient with acute kidney injury, which resolved the next day with IV hydration., Conclusion: Inpatient management of SER includes laboratory investigations, analgesia and hydration. Risk of complications is low in SER patients. SER patients without risk factors for complications can be considered for hospital-at-home management with bed rest, aggressive hydration and early outpatient review., Competing Interests: The authors report no conflict of interest or relationships with industry.

Objectives: This study aims to report the prevalence of cardiovascular risk factors (CVRFs) and other non-communicable diseases among migrant workers in Singapore admitted for COVID-19 infection, to highlight disease burden and the need for changes in health screening and healthcare delivery in this unique population., Setting: The study was conducted in the largest tertiary hospital in Singapore., Design: Retrospective cross-sectional study., Participants: 883 migrant workers who had mild or asymptomatic COVID-19 infection admitted to three isolation wards between 6 April 2020 and 31 May 2020 were included in this study., Outcome Measures: The outcome measures were the prevalence of pre-existing and newly diagnosed comorbid conditions and the prevalence of CVRFs-diabetes mellitus, hypertension and hyperlipidaemia-and non-communicable diseases at the time of discharge. The OR of having specific CVRFs depending on country of origin was generated via multivariate logistic regression analysis., Results: The median age of our study population was 45 years. 17.0% had pre-existing conditions and 25.9% received new diagnoses. Of the new diagnoses, 15.7% were acute medical conditions and 84.3% chronic medical conditions. The prevalence of CVRFs was higher in Southeast Asian and South Asian migrant workers compared with Chinese. The prevalence of non-communicable diseases on discharge was highest among Southeast Asians (49.4%)., Conclusions: The COVID-19 outbreak in a large number of migrant workers in Singapore unmasked a significant disease burden among them, increasing stakeholders' interests in their welfare. Moving forward, system-level changes are necessary to deliver healthcare sustainably and effect improvements in migrant workers' health., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: This study aims to estimate the prevalence of sinus tachycardia in hospitalized patients with mild COVID-19 infection and to identify the clinical, radiological, and biological characteristics associated with sinus tachycardia., Methods: A retrospective cohort study was conducted on patients with mild COVID-19 infection and sinus tachycardia during hospitalization. Outcomes measured included incidences of venous thromboembolism, high-dependency/intensive care unit admission, laboratory parameters, and radiological findings., Results: A total of 236 COVID-19 positive patients admitted to Singapore General Hospital isolation general wards from 1 June 2020 to 30 June 2020 were included in this study. Ninety-seven (41.1%) patients had sinus tachycardia on or during their admission. All patients were monitored in general wards and discharged to community quarantine facilities. None required oxygen support or high-dependency/intensive care unit admission. Sinus tachycardia was associated with increased C-reactive protein level (odds ratio = 1.033, 95% confidence interval = 1.002-1.066), abnormal chest X-ray findings (odds ratio = 3.142, 95% confidence interval = 1.390-7.104), and longer hospitalization (odds ratio = 1.117, 95% confidence interval = 1.010-1.236). There was no significant statistical association between sinus tachycardia and incidences of venous thromboembolism., Conclusion: This study suggests that patients with mild COVID-19 infection and concurrent sinus tachycardia are more likely to have higher inflammatory marker levels, abnormal imaging, and prolonged hospitalization. However, no significant association between sinus tachycardia and thromboembolism is identified in mild COVID-19 infection., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Medical students were temporarily removed from direct patient contact activities during the COVID-19 pandemic, shortening the duration of ward-based attachment programs. Web-based workshops were organized to equip final year medical students with necessary skills to start work in a general medicine setting. Topics included case-based scenarios reviewing patients with new complaints, medical documentation, and inter-professional communication. They were conducted using an online video conference platform and utilized polling platforms, small group discussions, and the "Chat" function to promote interactivity. Web-based learning enables delivery of useful contents without compromising interactivity and clinical applicability during the COVID-19 pandemic., (© International Association of Medical Science Educators 2020.)

An accurate determination of an individual's decision-making capacity is fundamental to obtaining informed consent for medical treatment, as it allows clinicians to balance respect for patients' autonomy with the best interests of patients. Despite the increasing demand for assessments of patients' capacity, healthcare professionals find this task complex and challenging. Currently, assessments are largely based on patients' cognitive ability and do not sufficiently take into account other factors that influence patients' judgment. Furthermore, it is important to assess for and treat modifiable factors that impair decision-making capabilities, and to have guidance on when it is appropriate to delay treatment-related decisions. This article will review current methods for assessing capacity, highlight other factors to consider in the decision-making process, and propose an enhanced framework to guide clinicians in making timely and prudent treatment-related decisions for patients with impaired capacity., (Copyright 2020 The Journal of Clinical Ethics.
