Perceived stress and associated factors among healthcare workers in a primary healthcare setting: the Psychological Readiness and Occupational Training Enhancement during COVID-19 Time (PROTECT) study

INTRODUCTION@#Disease outbreaks such as the COVID-19 pandemic significantly heighten the psychological stress of healthcare workers (HCWs). The objective of this study was to understand the factors contributing to the perceived stress levels of HCWs in a public primary care setting during the COVID-19 pandemic, including their training, protection and support (TPS), job stress (JS), and perceived stigma and interpersonal avoidance.@*METHODS@#This cross-sectional study using an electronic self-administered questionnaire was conducted at the National Healthcare Group Polyclinics in March 2020. Data was collected anonymously. Analysis was performed using regression modelling.@*RESULTS@#The response rate was 69.7% (n = 1,040). The mean perceived stress level of HCWs in various departments ranged from 17.2 to 20.3. Respondents who reported higher perceived stress were those who made alternative living arrangements, were more affected by the current pandemic, reported higher JS and were Muslims. Respondents who reported lower perceived stress were those who had been through the severe acute respiratory syndrome epidemic in 2003 and H1N1 pandemic in 2009 as HCWs, and those who had higher confidence in the organisation's TPS.@*CONCLUSION@#All HCWs, regardless of their scope of work, were similarly stressed by the current pandemic compared to the general population. Improving the confidence of HCWs in their training, protection and the support of personal protective equipment, and retaining experienced HCWs who can provide advice and emotional support to younger colleagues are important. Adequate psychological support for HCWs in the pandemic can be transformed into reserves of psychological resilience for future disease outbreaks.

COVID-19 in Singapore - a case series from primary care

As the COVID-19 pandemic worsens, early case detection is vital to limiting community spread. We describe our experiences with four COVID-19 cases at the polyclinics in January and February 2020. This retrospective case series highlights the challenges primary care clinicians face in the early identification of suspect cases based on clinical criteria only. To improve case detection, clinicians can sharpen their clinical acumen by keeping abreast with the latest COVID-19 developments and by maintaining a high state of vigilance.

Clinical Determinants of Diabetes Progression in Multiethnic Asians with Type 2 Diabetes - A 3-Year Prospective Cohort Study

INTRODUCTION@#The risk for diabetes progression varies greatly in individuals with type 2 diabetes mellitus (T2DM). We aimed to study the clinical determinants of diabetes progression in multiethnic Asians with T2DM.@*MATERIALS AND METHODS@#A total of 2057 outpatients with T2DM from a secondary-level Singapore hospital were recruited for the study. Diabetes progression was defined as transition from non-insulin use to requiring sustained insulin treatment or glycated haemoglobin (HbA1c) ≥8.5% when treated with 2 or more oral hypoglycaemic medications. Multivariable logistic regression (LR) was used to study the clinical and biochemical variables that were independently associated with diabetes progression. Forward LR was then used to select variables for a parsimonious model.@*RESULTS@#A total of 940 participants with no insulin use or indication for insulin treatment were analysed. In 3.2 ± 0.4 (mean ± SD) years' follow-up, 163 (17%) participants experienced diabetes progression. Multivariable LR revealed that age at T2DM diagnosis (odds ratio [95% confidence interval], 0.96 [0.94-0.98]), Malay ethnicity (1.94 [1.19-3.19]), baseline HbA1c (2.22 [1.80-2.72]), body mass index (0.96 [0.92-1.00]) and number of oral glucose-lowering medications (1.87 [1.39-2.51]) were independently associated with diabetes progression. Area under receiver operating characteristic curve of the parsimonious model selected by forward LR (age at T2DM diagnosis, Malay ethnicity, HbA1c and number of glucose-lowering medication) was 0.76 (95% CI, 0.72-0.80).@*CONCLUSION@#Young age at T2DM diagnosis, high baseline HbA1c and Malay ethnicity are independent determinants of diabetes progression in Asians with T2DM. Further mechanistic studies are needed to elucidate the pathophysiology underpinning progressive loss of glycaemic control in patients with T2DM.

Ethnic disparity in inter-arm systolic blood pressure difference and its determinants among Asians with type 2 diabetes: A cross-sectional study / Journal of the ASEAN Federation of Endocrine Societies

@#<p><strong>OBJECTIVES:</strong> An inter-arm difference in systolic blood pressure (IADSBP) of 10 mmHg or more has been associated with cardiovascular disease (CVD) and increased mortality in T2DM patients. We aim to study ethnic disparity in IADSBP and its determinants in a multi-ethnic T2DM Asian cohort.<br /><strong>METHODOLOGY:</strong> Bilateral blood pressures were collected sequentially in Chinese (n=654), Malays (n=266) and Indians (n=313). IADSBP was analyzed as categories (<br /><strong>RESULTS:</strong> Malays (27.4%) and Indians (22.4%) had higher prevalence of IADSBP ?10 mmHg than Chinese (17.4%) (p=0.002). After adjustment for age, gender, duration of diabetes, hemoglobin A1c, body mass index (BMI), heart rate, pulse wave velocity (PWV), estimated glomerular filtration rate (eGFR), albumin-to-creatinine ratio (ACR), smoking, hypertension, soluble receptor for advanced glycation end products (sRAGE), and usage of hypertension medications, ethnicity remained associated with IADSBP. While Malays were more likely to have IADSBP ?10 mmHg than Chinese (OR=1.648, 95%CI: 1.138-2.400, p=0.009), Indians had comparable odds with the Chinese. BMI (OR=1.054, 95%CI: 1.022-1.087, p=0.001) and hypertension (OR=2.529, 95%CI: 1.811-3.533, p<0.001) were also associated with IADSBP ?10 mmHg.<br /><strong>CONCLUSION:</strong> IADSBP in Malays were more likely to be ?10 mmHg than the Chinese which may explain their higher risk for CVD and mortality. Measuring bilateral blood pressures may identify high-risk T2DM individuals for intensive risk factor-management.</p>

The prevalence of albuminuria among diabetic patients in a primary care setting in Singapore

<p><b>INTRODUCTION</b>Microalbuminuria is an early sign of kidney damage. The prevalence of microalbuminuria in Singapore has been reported to be 36.0%-48.5%. However, the prevalence of microalbuminuria reported in these studies was determined with one urine sample using a qualitative urine test. The aim of this study was to determine the prevalence of micro- and macroalbuminuria using a more stringent criterion of two positive quantitative urine albumin-creatinine ratio (ACR) tests.</p><p><b>METHODS</b>We conducted a cross-sectional study of patients with type 2 diabetes mellitus (T2DM) who were followed up at a primary care clinic in Singapore. Patients were diagnosed to have albuminuria if they had two positive ACR tests within a seven-month period.</p><p><b>RESULTS</b>A total of 786 patients with T2DM met the study's inclusion criteria. 55.7% were already on an angiotensin-converting enzyme inhibitor (ACEI) and/or angiotensin receptor blocker (ARB). The prevalence rates of micro- and macroalbuminuria were 14.2% and 5.7%, respectively. Patients with albuminuria were more likely to have hypertension (odds ratio [OR] 3.47, 95% confidence interval [CI] 1.55-7.80). Diabetics with poorer diabetic control (OR 1.88, 95% CI 1.26-2.79), and higher systolic (OR 1.69, 95% CI 1.14-2.49) and diastolic (OR 1.96, 95% CI, 1.20 to 3.22) blood pressures were more likely to have albuminuria.</p><p><b>CONCLUSION</b>In the present study, the prevalence of microalbuminuria is significantly lower than that previously reported in Singapore. The presence of hypertension, poor diabetic control and suboptimal blood pressure control are possible risk factors for albuminuria in patients with T2DM.</p>

Acceptability of medical students by patients from private and public family practices and specialist outpatient clinics

<p><b>INTRODUCTION</b>Previous studies on patient acceptance of medical student teaching were from Western populations and in one setting only. However, there has been no prospective study comparing patient acceptability before and after an actual experience. We studied patient acceptability of medical student teaching in private and public family practices and public hospital specialist outpatient clinics in Singapore, and before and after an actual medical student teaching consultation.</p><p><b>MATERIALS AND METHODS</b>We conducted an anonymous cross-sectional survey from March through October 2007 of Singaporean or permanent resident patients attending 76 teaching private family practices, 9 teaching public family practices and 8 specialty clinics in a teaching public hospital. We used pre-consultation cross-sectional patient surveys in all three settings. For private family practice setting only, post-consultation patient survey was conducted after an actual experience with medical student presence.</p><p><b>RESULTS</b>Out of 5123 patients, 4142 participated in the cross-sectional survey (80.9%) and 1235 of 1519 patients in the prospective cohort study (81.3%). Eighty percent were comfortable with medical students present, 79% being interviewed and 60% being examined. Regarding being examined by medical students, parents of children were least comfortable while patients between 41 to 60 years were most comfortable (adjusted OR = 1.99 [1.55-2.57]). Females were less comfortable with medical student teaching than males. Chinese patients were the least comfortable about being interviewed or examined by medical students among the ethnic groups. Indians were most comfortable with being interviewed by medical students (adjusted OR = 1.38 [1.02-1.86]) but Malays were the most comfortable being examined by them (adjusted OR = 1.32 [1.07-1.62]). Family practice patients were more receptive to medical student teaching than the hospital's specialist outpatients. Common barriers to patient acceptance were lack of assurance of patient privacy, dignity and confidentiality. Actual exposure to medical student teaching did not change levels of patient acceptance.</p><p><b>CONCLUSIONS</b>Compared to similar studies from Western countries, Asian patients appear to be less receptive to medical student teaching than Western patients. Family practice settings offer medical students a more receptive learning environment.</p>
