Epidemiological and Clinical Predictors of COVID-19.

BackgroundRapid identification of COVID-19 cases, which is crucial to outbreak containment efforts, is challenging due to the lack of pathognomonic symptoms and in settings with limited capacity for specialized nucleic acid–based reverse transcription polymerase chain reaction (PCR) testing.MethodsThis retrospective case-control study involves subjects (7–98 years) presenting at the designated national outbreak screening center and tertiary care hospital in Singapore for SARS-CoV-2 testing from 26 January to 16 February 2020. COVID-19 status was confirmed by PCR testing of sputum, nasopharyngeal swabs, or throat swabs. Demographic, clinical, laboratory, and exposure-risk variables ascertainable at presentation were analyzed to develop an algorithm for estimating the risk of COVID-19. Model development used Akaike’s information criterion in a stepwise fashion to build logistic regression models, which were then translated into prediction scores. Performance was measured using receiver operating characteristic curves, adjusting for overconfidence using leave-one-out cross-validation.ResultsThe study population included 788 subjects, of whom 54 (6.9%) were SARS-CoV-2 positive and 734 (93.1%) were SARS-CoV-2 negative. The median age was 34 years, and 407 (51.7%) were female. Using leave-one-out cross-validation, all the models incorporating clinical tests (models 1, 2, and 3) performed well with areas under the receiver operating characteristic curve (AUCs) of 0.91, 0.88, and 0.88, respectively. In comparison, model 4 had an AUC of 0.65.ConclusionsRapidly ascertainable clinical and laboratory data could identify individuals at high risk of COVID-19 and enable prioritization of PCR testing and containment efforts. Basic laboratory test results were crucial to prediction models.

Incidence of facial pressure ulcers following surgery in the prone position - experience in a tertiary care hospital in Singapore

Introduction: The development of facial pressure ulcers after prone positioning is a well-known complication and a common source of patient dissatisfaction. Several risk factors have been identified in past studies. However, few studies have focused on the Asian population. We therefore set forth to identify the incidence of facial pressure ulcers following surgery in the prone position in our local population, as well as determine possible risk factors for their development. Methods: We recruited 132 patients who underwent elective surgery in a prone position under general anaesthesia in our tertiary hospital. The occurrence of facial pressure ulcers was analysed against several demographic and intraoperative factors. Statistical significance was taken as p Results: A total of 114 patients were included in the final analysis. The overall incidence of facial pressure ulcers was 35%. The most common locations were the cheeks (75%), and the forehead (43%). Increased age (OR 1.04 per year, p=0.035) and a prolonged duration of surgery (OR 2.05 per hour, p Conclusion: Facial pressure ulcers are common following surgery in a prone position in our local context. This first study on the Southeast Asian population corroborates with known risk factors for pressure ulcer development. Future studies may explore possible risk reduction measures to reduce the incidence of facial pressure ulcers in Southeast Asian populations.

Prevalence and antibiotic susceptibility of colistin-resistance gene (mcr-1) positive Enterobacteriaceae in stool specimens of patients attending a tertiary care hospital in Singapore

ObjectivesThe aim of this study was to determine the prevalence of the colistin-resistance gene (mcr-1) and the antibiotic-susceptibility profile of mcr-1 positive, colistin-resistant isolates in stool specimens of patients attending a tertiary care hospital in Singapore. Methods201 diarrheal stool specimens of patients attending the Changi General Hospital between May to August 2017 were collected and screened for the presence of mcr-1 by culture and molecular methods. Antibiotic-susceptibility profile of mcr-1 positive isolates was determined using the polymyxin B and colistin E-tests and the VITEK 2 system. ResultsWe observed an unexpectedly high prevalence of mcr-1 in patients attending a tertiary care hospital in Singapore, i.e 6.0% and 8.0% estimated by stool culture and direct stool PCR, respectively. The mcr-1 gene was detected predominantly in Escherichia coli. Antibiotic-susceptibility testing on 12 mcr-1 positive Enterobacteriaceae isolates revealed variable susceptibility profiles with no detection of carbapenem-resistant Enterobacteriaceae. ConclusionsThis is the first report of the prevalence of human faecal carriage of mcr-1 in Singapore. Our findings highlight the potential risk of mcr-1 spread among our patient cohort. The mcr-1 gene detection combined with the detection of other resistance gene targets of clinical importance is recommended to pre-empt the spread mcr-1 in our patients.

Combining quick sequential organ failure assessment score with heart rate variability may improve predictive ability for mortality in septic patients at the emergency department.

BackgroundAlthough the quick Sequential Organ Failure Assessment (qSOFA) score was recently introduced to identify patients with suspected infection/sepsis, it has limitations as a predictive tool for adverse outcomes. We hypothesized that combining qSOFA score with heart rate variability (HRV) variables improves predictive ability for mortality in septic patients at the emergency department (ED).MethodsThis was a retrospective study using the electronic medical record of a tertiary care hospital in Singapore between September 2014 and February 2017. All patients aged 21 years or older who were suspected with infection/sepsis in the ED and received electrocardiography monitoring with ZOLL X Series Monitor (ZOLL Medical Corporation, Chelmsford, MA) were included. We fitted a logistic regression model to predict the 30-day mortality using one of the HRV variables selected from one of each three domains those previously reported as strong association with mortality (i.e. standard deviation of NN [SDNN], ratio of low frequency to high frequency power [LF/HF], detrended fluctuation analysis α-2 [DFA α-2]) in addition to the qSOFA score. The predictive accuracy was assessed with other scoring systems (i.e. qSOFA alone, National Early Warning Score, and Modified Early Warning Score) using the area under the receiver operating characteristic curve.ResultsA total of 343 septic patients were included. Non-survivors were significantly older (survivors vs. non-survivors, 65.7 vs. 72.9, p <0.01) and had higher qSOFA (0.8 vs. 1.4, p <0.01) as compared to survivors. There were significant differences in HRV variables between survivors and non-survivors including SDNN (23.7s vs. 31.8s, p = 0.02), LF/HF (2.8 vs. 1.5, p = 0.02), DFA α-2 (1.0 vs. 0.7, P < 0.01). Our prediction model using DFA-α-2 had the highest c-statistic of 0.76 (95% CI, 0.70 to 0.82), followed by qSOFA of 0.68 (95% CI, 0.62 to 0.75), National Early Warning Score at 0.67 (95% CI, 0.61 to 0.74), and Modified Early Warning Score at 0.59 (95% CI, 0.53 to 0.67).ConclusionsAdding DFA-α-2 to the qSOFA score may improve the accuracy of predicting in-hospital mortality in septic patients who present to the ED. Further multicenter prospective studies are required to confirm our results.

Do antimicrobial stewardship programme interventions reduce the rate of and protect against Clostridium difficile infection?

Antimicrobial stewardship programmes (ASPs) have often been recommended as a viable solution to minimise the incidence of Clostridium difficile infection (CDI), which can be life-threatening. This study aimed to evaluate whether ASP interventions have contributed to reducing CDI rates. A retrospective review of ASP interventions issued from January 2013 to April 2014 was performed using data from the ASP database of Singapore General Hospital, a 1600-bed tertiary-care hospital in Singapore. A total of 283 interventions satisfied the inclusion criteria, of which commonly audited antibiotics were piperacillin/tazobactam (41.3%) and carbapenems (54.8%). Comparisons were made at 30days post-intervention between those with accepted or rejected interventions. The primary outcome was CDI incidence; secondary outcomes included length of hospitalisation post-intervention, 30-day mortality and CDI recurrence rate. Whilst the median duration of antibiotic therapy was reduced by 2days (6days vs. 4 days; P<0.001), acceptance of ASP interventions did not alter primary CDI incidence at 30days (P=0.644) post-intervention. However, reduced CDI recurrence rates were observed for patients positive for CDI in the accepted patient group compared with the rejected group (0% vs. 37.5%; P=0.03), with no difference in CDI 30-day mortality between the two groups. Intervention acceptance did not contribute to a significant reduction in CDI incidence but may be associated with lower recurrence rates, although further studies are required.

Genetic Polymorphisms and Cytokine Profile of Different Ethnicities inSeptic Shock Patients and their Association with Mortality.

ABSTRACTObjectiveThe outcomes of sepsis and septic shock patients are heterogonous, with avariable response despite standardized care. The aim of this study was toexplore the racial differences in septic shock outcomes, and theirassociation with genetic polymorphisms and cytokine levels in an Asianpopulation.Materials and methodsThis was an observational cohort study with Intensive Care units of a 500bedded tertiary care hospital in Singapore. 198 patients (73 Chinese, 73Malay and 52 Indian and others) admitted to the Khoo Teck Puat HospitalIntensive Care Unit between August 2016 and June 2017, with a diagnosis ofsevere sepsis (according to) were enrolled. Plasma interlukin-6 (IL-6),interlukin-10 (IL-10) and tumour necrosis factor-a (TNFa) were measuredusing a highly sensitive quantitative sandwich enzyme-linked immunosorbentassay (ELISA) (BioVendor, Modrice, Czech Republic). The gene panel studiedincluded 16 genes.ResultsThe rs7038903 common variant in SVEP1 gene showed significant associationwith sepsis severity independent of other variants in ordinal logistic andlinear regression model (p = 0.001 and p = 0.002 respectively). Moreover, the association between rs7038903 and increased hazard for death remained significant after further adjusting for cytokines level. Interestingly, significant differences were seen in plasma IL6 inindividuals with or without rs7038903 C allele (28pg/ml (IQR 12-86) vs90pg/ml (IQR 49-155); P=0.022) in patients with severe sepsis in the Malayethnic group.ConclusionOur study shows a promising polymorphism in SVEP1 gene (rs7038903) which isassociated with sepsis shock and 28 days mortality, independent of age, gender, and method of diagnosis and SOFA score. Collectively, while our findings so far have shown the additional value or measuring cytokines andgenetic markers in sepsis outcomes in the local population, further largescare studies are needed in a heterogeneous septic population with arigorous analysis to know the significance of our findings.How to cite this articleSiddiqui S, Gurung RL et al.

The burden of methicillin-resistant staphylococcus aureus infections among hospitalised patients in singapore

Background: MRSA has caused enormous burden to affected Western patients and society. However, only limited study results originated from the Asia-Pacific populations.&#x0D; Aim: To assess the burden of Methicillin-resistant S. aureus infections (MRSA) among patients from a large tertiary care hospital in Singapore.&#x0D; Methods: Retrospective study using data from the hospital discharge database to identify patients with MRSA and Methicillin-sensitive S. aureus infections (MSSA) using International Statistical Classification of Diseases and Related Health Problems, 9th Revision, Australian Modification (ICD-9-AM) codes. &#x0D; Findings: Amongst 543,068 hospitalized patients between 2004 and 2010, 8,664(1.6%) were infected with S. Aureus, including 4,868(0.9%) with MRSA. Compared with uninfected controls, MRSA patients had longer hospital stay (geometric mean, GM, 12.2 vs. 3.0 days), higher hospitalization costs (GM, $6294.7 vs. $2295.7), higher in-hospital mortality rate (7.8% vs. 2.8%) and higher 30-day all-cause unscheduled readmission rate (36.3% vs. 23.7%, all p&lt;0.001). The difference still existed after adjustment for age groups, gender, ethnicity, medical management, and Charlson comorbidity index. Similarly, MRSA patients had longer hospital stay, higher hospitalization costs, higher in-hospital mortality rate and 30-day all-cause unscheduled readmission rate compared with patients with MSSA.&#x0D; Conclusion: MRSA infection was associated with poor clinical outcomes and higher economic burden in this population. Prevention and control measures should be implemented both inside and outside the hospital setting.

High one-year mortality following hospitalization for severe hypoglycemia among patients with diabetes mellitus: findings of a retrospective cohort study at an acute tertiary care hospital in Singapore

Objectives: Little is known about the 1-year short-term mortality rate following hospital admissions with severe hypoglycemia. This study aimed to determine the factors associated with increased 1-year mortality rate following hospitalization in diabetes patients admitted with severe hypoglycemia to the Singapore General Hospital.Methods: Clinical, biochemical, and 1-year mortality data from diabetes patients who were admitted with severe hypoglycemia in the year 2014 were extracted from institutional medical records. Patients who passed away during the episode of admissions with severe hypoglycemia were excluded from the analysis. The clinical and biochemical factors between patients who survived and those who did not survive within 1 year following admission were compared using logistic regression analysis.Results: Three hundred and four patients (181 female and 123 male) were admitted with severe hypoglycemia in 2014, and the mean capillary blood glucose on admission was 2.3 ± 0.7 mmol/L. Sixty-three (20.7%) patients died within 1-year post-discharge from the hospital. Compared with patients who survived 1-year post-discharge from the hospital, non-survivors were older (69.3 ± 11.0 vs 75.5 ± 11.2 years, p < .001), had longer lengths of stay (LOS) (5.0 ± 7.4 vs 9.0 ± 12.8 days, p = .02), and had a higher Charlson Comorbidity Index (CCI) (4.1 ± 1.9 vs 5.9 ± 2.4, p < .001). Factors associated with increased 1-year mortality risk were age (odds ratio [OR] = 1.06; 95% confidence interval [CI] = 1.03–1.09, p < .01), LOS in hospital (OR = 1.01; 95% CI = 1.01–1.08, p < .01), and CCI (OR = 1.51; 95% CI = 1.31–1.75, p < .01), respectively.Conclusions: Older diabetes patients with more comorbidities and longer LOS were at increased risk of dying within a year of discharge after hospitalization with severe hypoglycemia. Admission with severe hypoglycemia has important prognostic implications. Healthcare professionals should address hypoglycemia and other health issues during the hospital admissions.

Factors influencing seasonal influenza vaccination uptake among health care workers in an adult tertiary care hospital in Singapore: A cross-sectional survey

This study aimed to evaluate the factors influencing seasonal influenza vaccination uptake among different health care professional groups. A single-center, cross-sectional survey using a standardized anonymous, self-administered questionnaire to assess knowledge, attitudes, and uptake of seasonal influenza vaccination was used. Associations between respective health care groups and vaccination acceptance were then assessed. In total, 3,873 health care workers completed the questionnaire. Of these, 7% were administrative staff, 17% were allied health staff, 7% were ancillary staff, 11% were medical staff, and 58% were nursing staff. The overall vaccination rate for the Southern Hemisphere 2015 influenza season was 82%. In a multivariate logistic regression model, after controlling for gender and presence of chronic disease, associated factors for accepting influenza vaccination were age, education level of bachelor degree or higher, preference for vaccination provided by mobile teams, having 1-50 patient contacts per week, and belief in the potential severity of influenza and vaccine safety (P < .05). In contrast, factors negatively associated with vaccination acceptance included being a medical staff member or allied health staff member, living with family members under the age of 16, fear of adverse reactions, and disbelief in vaccination effectiveness (P < .05). Although vaccine coverage in Singapore has been high, our findings provide guidance for the development of strategies to further improve vaccine coverage among different groups of health care workers.

Correction: A knowledge, attitude, and practice survey on mediation among clinicians in a tertiary-care hospital in Singapore.

[This corrects the article DOI: 10.1371/journal.pone.0199885.].

A knowledge, attitude, and practice survey on mediation among clinicians in a tertiary-care hospital in Singapore.

Healthcare delivery is a highly complex, deeply personal and costly endeavour that involves multiple specialties and services. There is an imbalance in knowledge between the healthcare provider and consumer that may contribute to doubts and uncertainty over treatment and outcomes. It is unsurprising that conflict and dispute can develop between healthcare providers and patients and their next-of-kin. The use of mediation in the healthcare setting has recently been promoted in many developed countries, including Singapore. We administered a detailed 32-item survey in a large tertiary-care teaching hospital to improve our understanding of the knowledge, attitude and practice of dispute resolution among clinicians to pave the way for better strategies to improve the adoption of mediation in healthcare setting. Ninety-seven respondents had an average of 62% (SD: 12%) knowledge score. The most common misconceptions held by the respondents about mediation were: (1) mediation was about fact-finding, (2) mediation is limited to only certain types of dispute, (3) mediation proceeds by both parties giving their account of the dispute, then a third party decides a settlement, (4) the average time it takes to resolve a dispute through mediation, (5) the cost of mediation, (5) the venue of mediation, (6) the person determining the outcome of mediation, (7) confidentiality of mediation. In general, the respondents were positive about the use of mediation as a dispute resolution tool. When asked to indicate the relative importance of different outcomes of dispute resolution, financial compensation and waiver of hospital bill attracted mixed responses while understanding facts of dispute, assurance that the same error would not recur, and offering corrective treatment were rated as being important. By contrast, seeking an apology from the complainant was considered neutral to somewhat important and the respondents were least concerned with the publicity of the dispute. Direct negotiation with the complainant was considered the most time- and cost-efficient means of resolving a dispute while the opposite was true for litigation. Mediation was considered the approach where the clinicians are most likely to achieve their desired outcome while litigation was considered least likely to produce a favourable outcome. Approximately half of the respondents reported having personal experience or known of a colleague who had been involved in a medico-legal dispute. A quarter of these cases were resolved by direct negotiations with the complainant while lawyers, the judge and mediation, resolved approximately 15% each, respectively. The knowledge base of the clinicians in this study about mediation was moderate and probably reflected the general lack of direct experience in the resolution of a dispute or training in mediation. This further corroborated with the general response that the uptake of mediation in the healthcare setting is currently poor in Singapore due to the lack of awareness and perceived lack of avenue among the surveyed clinicians. Any further work to be done with clinicians may be in the direction of (1) increasing general understanding of mediation, (2) increasing awareness of avenues for mediation, and (3) becoming better aware of when to propose mediation.

Differences in psychosocial determinants of hand hygiene between health care professional groups: Insights from a mixed-methods analysis

Good hand hygiene (HH) prevents health care-associated infections. We compared psychosocial and organizational factors associated with HH compliance and perceived need for improvement among physicians, nurses, and allied health professionals (AHPs). We conducted a mixed-methods study in a 1,600-bed adult tertiary-care hospital in Singapore. Seven focus group discussions were conducted and data were analyzed using thematic analysis. The subsequent cross-sectional survey involved 1,064 staff members. Principal components analysis was performed to derive the latent factor structure that was applied in multivariable analyses. All staff members acknowledged that HH was an integral part of their work, but were noncompliant due to competing priorities. Physicians were forgetful but appreciated reminders. Nurses were intrinsically motivated for HH. After adjusting for gender, staff category, seniority, and dermatitis history, having positive knowledge-attitudes-behaviors (odds ratio [OR], 1.44; 95% confidence interval [CI], 1.23-1.69), personal motivators-enablers (OR, 1.60; 95% CI, 1.38-1.86), and emotional motivators (OR, 1.62; 95% CI 1.40-1.88) were positively associated with good HH compliance. Women (OR, 3.91; 95% CI, 1.37-11.11), seniors (OR, 2.88; 95% CI, 1.08-7.68), nurses (OR, 4.05; 95% CI, 1.51-10.87), and staff with personal motivators-enablers for HH (OR, 1.60; 95% CI, 1.08-2.37) were more likely to perceive a need for improvement. Factors influencing self-reported HH differed between health care professional groups. Group-specific interventions are needed to improve compliance.

Point-of-Care Testing in an Acute Tertiary Care Hospital in Singapore

Point-of-care testing (POCT) in our tertiary care hospital is embedded in the daily clinical processes. In 2005, the central laboratory was tasked with POCT oversight to align compliance to hospital accreditation standards. With 10 years that has since ensued, the hospital signalled a fresh relook at the agenda to ensure needs in the next lap of the hospital's reorganization are met. A multidisciplinary POCT committee was formed, and it implemented an executive framework and updated processes for current and new point-of-care (POC) tests/devices. A central repository of standardized operating procedures and quality control and training documents was put in place, and in-house quality assurance tests for POC glucose and blood gases organized by the hospital's central laboratory were scheduled to be replaced with subscription to external quality assurance programs. The revised POCT policy was shared with all stakeholders, the physicians and nurses, to facilitate a smooth transition. A shared vision to further enhance governance and institutionalize POC activities remains a key priority.

Psychometric Properties of the Chinese Version of the Acceptance of Chronic Health Conditions (Stoma) Scale for Patients With Stoma.

Formation of a stoma is a common outcome in surgical treatment of colorectal cancer. A higher acceptance of stoma was shown to improve quality of life of patients. No instrument in Chinese is available that can be used to measure the acceptance of stoma among patients with colorectal cancer. The aims of this study were to translate and test the psychometric properties of Chinese version of Acceptance of Chronic Health Conditions (ACHC) (Stoma) scale. A sample of 100 Chinese-speaking patients with stoma was recruited from a public tertiary care hospital in Singapore. The scale was translated into Chinese and reviewed by an expert panel for semantic equivalence and content validity testing. Convergent validity was established by exploring correlations between scores of the Chinese version of the ACHC (Stoma) scale and those of the 5-level version of European Quality of Life Questionnaire-5 Dimensions. Reliability was assessed by internal consistency and test-retest reliability. The newly translated scale had high content validity (content validity index = 94%) and acceptable internal consistency (Cronbach's α = .846). The test-retest reliability was satisfactory with an intraclass coefficient of 0.997. A positive correlation was found between both scores on ACHC (Stoma) scale and EQ-5D utility score (r = 0.63, P < .01) and EQ-5D global visual analog scale (r = 0.70, P < .01). The Chinese version of the ACHC (Stoma) scale demonstrated satisfactory content validity, good convergent validity, and adequate internal consistency and stability. This scale can be used as a convenient screening tool in clinical settings to assess the level of acceptance in Chinese-speaking patients with stoma.

Risk assessment and laboratory investigation of respiratory illness in travellers returning to Singapore 2012-2015: experience from the MERS-CoV Surveillance Programme.

Since the emergence of Middle East respiratory syndrome coronavirus (MERS-CoV), Singapore has enhanced its national surveillance system to detect the potential importation of this novel pathogen. Using the guidelines from the Singapore Ministry of Health, a suspect case was defined as a person with clinical signs and symptoms suggestive of pneumonia or severe respiratory infection with breathlessness, and with an epidemiological link to countries where MERS-CoV cases had been reported within the preceding 14 days. This report describes a retrospective review of 851 suspected MERS-CoV cases assessed at the adult tertiary-care hospital in Singapore between September 2012 and December 2015. In total, 262 patients (31%) were hospitalized. All had MERS-CoV infection ruled out by RT-PCR or clinical assessment. Two hundred and thirty (88%) of the hospitalized patients were also investigated for influenza virus by RT-PCR. Of these, 62 (27%) tested positive for seasonal influenza. None of the patients with positive influenza results had been vaccinated in the year prior to hospital admission. Ninety-three (36%) out of the 262 hospitalized patients had clinical and/or radiological evidence of pneumonia. This study demonstrates the potential benefits of pre-travel vaccination against influenza and pneumococcal disease.

Mortality Benefits of Antibiotic Computerised Decision Support System: Modifying Effects of Age.

Antibiotic computerised decision support systems (CDSSs) are shown to improve antibiotic prescribing, but evidence of beneficial patient outcomes is limited. We conducted a prospective cohort study in a 1500-bed tertiary-care hospital in Singapore, to evaluate the effectiveness of the hospital’s antibiotic CDSS on patients’ clinical outcomes, and the modification of these effects by patient factors. To account for clustering, we used multilevel logistic regression models. One-quarter of 1886 eligible inpatients received CDSS-recommended antibiotics. Receipt of antibiotics according to CDSS’s recommendations seemed to halve mortality risk of patients (OR 0.54, 95% CI 0.26–1.10, P = 0.09). Patients aged ≤65 years had greater mortality benefit (OR 0.45, 95% CI 0.20–1.00, P = 0.05) than patients that were older than 65 (OR 1.28, 95% CI 0.91–1.82, P = 0.16). No effect was observed on incidence of Clostridium difficile (OR 1.02, 95% CI 0.34–3.01), and multidrug-resistant organism (OR 1.06, 95% CI 0.42–2.71) infections. No increase in infection-related readmission (OR 1.16, 95% CI 0.48–2.79) was found in survivors. Receipt of CDSS-recommended antibiotics reduced mortality risk in patients aged 65 years or younger and did not increase the risk in older patients. Physicians should be informed of the benefits to increase their acceptance of CDSS recommendations.
