More people are traveling to remote places for leisure and business. It is not uncommon for patients to get medication and advice for travel to high altitudes. Although high altitude cerebral and pulmonary oedemas are more frequent at very high and extreme altitudes, they may sometimes occur at lower altitudes and lead to fatalities. Even though acute mountain sickness (AMS) is generally deemed benign, it can easily wreck a holiday. The Lake Louise Score Questionnaire is a useful screening tool for AMS and it can be self-administered during travel. Non-pharmacological means in the prevention and treatment of AMS, especially acclimatisation, are the most important. Pharmacological prevention and treatment strategies should be used as a useful adjunct. This paper provides an approach to the provision of education and advice for high altitude travel in the primary care setting.

INTRODUCTION: Single-disease clinical practice guidelines (CPGs) are not designed to consider patients with multiple chronic conditions, or multimorbidity. Applying multiple CPGs to a single patient may create an overwhelming treatment burden resulting in poor adherence and clinical outcomes. No studies on the cumulative treatment burden from multiple CPGs have been done in Singapore. We described the treatment burden on a hypothetical patient with six chronic conditions when multiple CPGs were applied, and appraised each CPG with respect to the patient-centred care of older adults with multimorbidity. METHODS: A treatment plan was developed for a hypothetical 72-year-old woman with asthma, depression, diabetes mellitus, dyslipidaemia, hypertension and osteoarthritis according to the latest CPG recommendations. Treatment burden was quantified in terms of time spent, cost, and the number of appointments and medications. Each CPG was appraised with respect to the care of older adults, patients with multimorbidity and patient-centred care. RESULTS: Following the CPGs strictly, an average of about two hours was spent daily taking 14 different medications and following 21 non-pharmacological recommendations. Her out-of-pocket payment was SGD 104.42 monthly despite a near 90% subsidy on healthcare bills. Patient-centred care of older adults with multimorbidity was inadequately addressed in all six CPGs. CONCLUSION When six CPGs were cumulatively followed, the treatment burden was time-consuming, costly and disruptive. Patients' goals and preferences must guide prioritisation of care such that treatment burden remains minimally disruptive to their lives. Developing future CPGs to deliver patient-centred rather than disease-focused care will be crucial to the management of multimorbidity.

INTRODUCTION: Studies of concordance between patients' self-report of diseases and a criterion standard (e.g. chart review) are usually conducted in epidemiological studies to evaluate the agreement of self-reported data for use in public health research. To our knowledge, there are no published studies on concordance for highly prevalent chronic diseases such as diabetes and pre-diabetes. The aims of this study were to evaluate the concordance between patients' self-report and their medical records of diabetes and pre-diabetes diagnoses, and to identify factors associated with diabetes concordance. METHOD: A cross-sectional, interviewer-administered survey was conducted on patients with chronic diseases after obtaining written consent to assess their medical notes. Interviewers were blinded to the participants' profiles. Concordance was evaluated using Cohen's kappa (κ). A multivariable logistic regression model was used to identify factors associated with diabetes concordance. RESULTS: There was substantial agreement between self-reported and medical records of diabetes diagnoses (κ=0.76) and fair agreement for pre-diabetes diagnoses (κ=0.36). The logistic regression model suggested that non-Chinese patients had higher odds of diabetes concordance than Chinese patients (odds ratio [OR]=4.10, 95% confidence interval [CI] 1.19-14.13, P=0.03). Patients with 3 or more chronic diseases (i.e. multimorbidity) had lower odds of diabetes concordance than patients without multimorbidity (OR=0.21, 95% CI 0.09-0.48, P<0.001). CONCLUSION Diabetes concordance was substantial, supporting the use of self-report of diabetes by patients with chronic diseases in the primary care setting for future research. Pre-diabetes concordance was fair and may have important clinical implications. Further studies to explore and improve health literacy and patient-physician communication are needed.

INTRODUCTION: The rising prevalence of multiple chronic diseases is an important public health issue as it is associated with increased healthcare utilisation. This paper aimed to explore the annual per capita healthcare cost in primary care for patients with multiple chronic diseases (multimorbidity). METHODS: This was a retrospective cohort study conducted in a cluster of public primary care clinics in Singapore. De-identified data from electronic medical records were extracted from July 2015 to June 2017. Only patients with at least 1 chronic disease were included in the study. Basic demographic data and healthcare cost were extracted. A list of 20 chronic diseases was considered for multimorbidity. RESULTS: There were 254,377 patients in our study population, of whom 52.8% were female. The prevalence of multimorbidity was 62.4%. The median annual healthcare cost per capita for patients with multimorbidity was about twice the amount compared to those without multimorbidity (SGD683 versus SGD344). The greatest percentage increment in cost was when the number of chronic diseases increased from 2 to 3 (43.0%). CONCLUSION Multimorbidity is associated with higher healthcare cost in primary care. Since evidence for the optimal management of multimorbidity is still elusive, prevention or delay in the onset of multimorbidity in the general population is paramount.

INTRODUCTIONMicroalbuminuria 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.

METHODSWe 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.

RESULTSA 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.

CONCLUSIONIn 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.

INTRODUCTION: Patients with chronic diseases face difficulties when navigating the healthcare system. Using the Healthcare System Hassles Questionnaire (HSHQ) developed by Parchman et al, this study aimed to explore the degree of hassles faced by patients in primary care in Singapore and identify the characteristics associated with greater hassles. METHODS: A cross-sectional study was conducted on patients with chronic diseases at Hougang Polyclinic, Singapore, using the interviewer-administered HSHQ. The mean HSHQ score was compared with that reported by Parchman et al. The associations between the number of chronic diseases, demographic variables and healthcare hassles were assessed using multivariate linear logistic regression analysis. RESULTS: In total, 217 outpatients aged 21 years and above were enrolled. Their overall mean HSHQ score (4.77 ± 6.18) was significantly lower than that of patients in the study by Parchman et al (15.94 ± 14.23, p < 0.001). Patients with five or more chronic diseases scored 3.38 (95% confidence interval [CI] 0.11-6.65, p = 0.043) points higher than those with one chronic disease did. With each increasing year of age, the mean HSHQ score decreased by 0.17 (95% CI -0.26 to -0.08, p = 0.001) points. Patients with polytechnic/diploma/university education and higher scored 2.65 (95% CI 0.19-5.11, p = 0.035) points higher than those with primary education and lower did. CONCLUSION Patients in our population reported less hassles than those in the study by Parchman et al did. Increasing age and lower education level were associated with less hassles. Further analysis of the types of chronic diseases may yield new information about the association of healthcare hassles with the number and types of chronic diseases.

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.

Aim: To examine the trend of youth depression diagnosed in a healthcare group in Singapore over a 6-year period. Methods: This is a retrospective analysis of the medical records of patients who had been diagnosed with depression from Jan 2013 to Dec 2018 in a healthcare group in Singapore. The yearly trend of depression diagnosis among the youths (10-24 years of age) was compared with adults (25-64 years of age) and the elderly (≥ 65 years of age). The mean age at diagnosis, distribution of gender, ethnicity and clinical care settings among the subgroup of youth patients were compared across the years using analysis of variance or Pearson’s chi-square test. Results: A total of 4701 youths, 15243 adults and 6908 elderly patients were included in the analysis. Between 2013 and 2018, the rise in depression diagnosis in the youth was greater than in the adult and elderly populations, and the mean age at diagnosis decreased from 49.7 ± 0.3 (mean ± SE) years in 2013 to 39.6 ± 0.3 years in 2018. Among the youths, more females had been diagnosed with depression than males and females displayed a larger increase in diagnosis of depression. There was also a larger increase in the diagnosis of depression in primary care compared to emergency departments, outpatient specialist clinics and in-hospital wards. Conclusion Youth depression is a major health problem in Singapore. There is a need for the expansion of resources in a variety of avenues for depressed youths to seek help.
