INTRODUCTIONAsthma is a common childhood disease, and paediatric patients with asthma rely on caregivers to administer domiciliary asthma care. This study aimed to explore the knowledge, understanding, perceptions and main concerns of caregivers and its influence on their home management of children with asthma.

METHODSData from 14 caregivers of children with asthma was collected during three focus group discussions held in two polyclinics in Singapore. The collected data was analysed using standard content analysis and classified into themes.

RESULTSThe caregivers' main concerns included the perceived effects of infection, food and exercise on children with asthma. Several caregivers considered the disease to be infectious and had a lower threshold for physician consultation, as they believed that any delay in treating the infection would be detrimental to the child's health. Some also perceived asthma to be episodic and self-limiting, and that their children could 'outgrow' it. Many caregivers believed that asthma could be modified by abstinence from, or intake of, certain foods. Others had the perception that sports, including swimming, would worsen asthma. These perceptions resulted in unnecessary restrictions of the children's diet and activities. Most caregivers were unaware of influenza vaccination as a preventive measure to reduce triggers due to respiratory viral infections.

CONCLUSIONWe found that the caregivers' perceptions of asthma aetiology, its triggers and preventive measures affected their help-seeking behaviour and care of children with asthma. Healthcare professionals managing paediatric patients with asthma should recognise such caregiver misperceptions, and take a proactive approach to rectify and bridge the gaps in caregivers' knowledge and understanding of the disease.

INTRODUCTIONThe Singapore National Asthma Program (SNAP) was launched in 2001 to address the high burden of asthma in Singapore. One component of the SNAP was directed at improving asthma control in the community by promoting preventive treatment with inhaled corticosteroids. This paper describes the program on prescription patterns of preventor and reliever medication for asthma in the polyclinics.

MATERIALS AND METHODSWe monitored the prescription pattern for asthma as the preventor-reliever (PR) drug ratio. The PR ratio was employed both as a positive feedback tool and as a key performance indicator (KPI) for the program. Individual clinics were encouraged to implement locally relevant and effective initiatives to increase the KPI and facilitate this process. The different methods included chronic care models, multidisciplinary teams, enhanced primary care clinics, pre-counselling screening, decision support tools, self-management support, a patient information system and community education.

RESULTSIn the course of the program, the case load for asthma in the polyclinics increased by 31%. During the same period, the average PR ratio increased significantly from 0.68 to 1.80 (P <0.001).

CONCLUSIONSA simple audit and positive feedback program based on PR ratios, accompanied by sustained local quality improvement cycles has been associated with a significant shift in the drug treatment of asthma away from episodic quick relief medication towards long-term daily preventive treatment with inhaled steroids in polyclinics.

Introduction: Achieving optimal glycated hemoglobin (HbA1c), blood pressure (BP), and LDLCholesterol (LDL-C) in patients mitigates macro- and micro-vascular complications, which is the key treatment goal in managing type 2 diabetes mellitus (T2DM). This study aimed to determine the proportion of patients in an urban community with T2DM and the above modifiable conditions attaining triple vascular treatment goals based on current practice guidelines. Methods: A questionnaire was distributed to adult Asian patients with dyslipidemia at two primary care clinics (polyclinics) in northeastern Singapore. The demographic and clinical data for this sub-population with both T2DM and dyslipidemia were collated with laboratory and treatment information retrieved from their electronic health records. The combined data was then analyzed to determine the proportion of patients who attained triple treatment goals, and logistic regression analysis was used to identify factors associated with this outcome. Results: 665 eligible patients [60.5% female, 30.5% Chinese, 35% Malays, and 34.4% Indians] with a mean age of 60.6 years were recruited. Of these patients, 71% achieved LDL-C ≤2.6 mmol/L, 70.4% had BP <140/90 mmHg, and 40.9% attained HbA1c ≤7%. Overall, 22% achieved the triple treatment goals for glycemia, BP, and LDL-C control. The major determinants were the number of diabetic medications and intensity of statin therapy. Conclusion: Eight in ten patients with T2DM failed to achieve concurrent glycemic, BP, and LDL-C treatment goals, subjecting them to risks of vascular complications. Primary healthcare professionals can mitigate these risks by optimizing therapeutic treatment to maximize glycemia, dyslipidemia, and BP control.

INTRODUCTION: Physical activity (PA) and sedentary behaviour (SB) independently influence the health outcomes of older adults. Both provide interventional opportunities for successful ageing. We aimed to determine levels of PA and SB in ambulatory older adults and their associated factors in a developed Asian population known for its longevity. METHODS: We conducted a cross-sectional observational study in a Singapore public primary healthcare centre. Multi-ethnic Asian adults aged ≥ 60 years took an interviewer-administered questionnaire survey. PA and SB were assessed using the Physical Activity Scale for the Elderly (PASE; score range 0 to > 400) and the Sedentary Behaviour Questionnaire for the Elderly, respectively. RESULTS: Among 397 participants (50.9% female; 73.2% Chinese; 47.9% aged ≥ 70 years; 33.5% employed, including voluntary work), 58.7% had ≥ 3 chronic illnesses and 11.1% required walking aids. The median PASE score was 110.8 (interquartile range 73.8-171.6) and decreased significantly with increasing age. Higher PASE score was associated with higher educational level, employment, independent ambulation without aid, and fewer chronic illnesses (p < 0.01). Employment status significantly influenced PASE score (β = 84.9, 95% confidence interval [CI] 66.5-103.4; p < 0.01). 37.0% spent ≥ 8 hours daily on sedentary activity and were twice as likely to do so if they were employed (odds ratio 2.19, 95% CI 1.34-3.59; p < 0.01). CONCLUSION The PA of the older adults decreased with increasing age and increased with employment. One-third of them were sedentary for ≥ 8 hours daily. Those who were employed were twice as likely to have SB.

INTRODUCTIONDyslipidaemia leads to atherosclerosis and is a major risk factor for cardiovascular diseases. In clinical trials, 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, or statins, have been shown to effectively reduce dyslipidaemia. Despite the availability and accessibility of statins, myocardial infarctions and cerebrovascular accidents remain among the top causes of mortality in developed countries, including Singapore. This enigma could be attributed to suboptimal adherence to statin therapy. The present literature review aimed to evaluate patients' perceptions of statin therapy.

METHODSWe searched PubMed and other databases for articles published in English from October 1991 to May 2012 containing keywords such as 'patient', 'views', 'perceptions', 'adherence', 'statin' and 'dyslipidaemia'. Of the 122 eligible studies retrieved, 58 were reviewed. The findings were categorised and framed in accordance with the Health Belief Model.

RESULTSPatients with dyslipidaemia appeared to underestimate their susceptibility to dyslipidaemia-related complications, partly due to their demographic profiles. Failure to appreciate the severity of potential complications was a major hindrance toward adherence to statin therapy. Other factors that affected a patient's adherence included lack of perceived benefits, perceived side effects, the cost of statins, poor physician-patient relationship, and overestimation of the effectiveness of diet control as a treatment modality.

CONCLUSIONExisting evidence suggests that the cause of poor adherence to statin therapy is multifactorial. The use of the Health Belief Model to present the results of our literature review provides a systematic framework that could be used to design a patient-centric approach for enhancing adherence to statin therapy.

Singapore is facing an increasing noncommunicable disease burden due to its ageing population. Singapore's primary healthcare services, provided by both polyclinic physicians and private general practitioners, are available to the public at differential fees for service. The resultant disproportionate patient loads lead to dissatisfaction for both healthcare providers and consumers. This article describes the 'PAIR UP' approach as a potential endeavour to facilitate primary care physicians (PCPs) in public and private sectors to collaborate to deliver enhanced primary care in Singapore. PAIR UP is an acronym referring to Policy, Academic development, Integration of healthcare information system, Research in primary care, Utility and safety evaluation, and Practice transformation. The current healthcare landscape is favourable to test out this multipronged approach. PCPs in both sectors can ride on it and work together synergistically to provide quality primary care in Singapore.

AIMTo explore the barriers faced by general practitioners (GPs) in the management of patients with erectile dysfunction (ED).

METHODSThis was a qualitative analysis of focus group discussions and in-depth interviews involving 28 Malaysian GPs.

RESULTSGPs' perception of ED being not a serious condition was a major determinant of their prescribing practice. Doctor's age (younger), gender (female), short consultation time and lack of experience were cited as barriers. The GPs' prescribing habits were heavily influenced by the feedback from the first few patients under treatment, the uncertainty of etiology of ED without proper assessment and the profit margin with bulk purchase. Other barriers include Patients' coexisting medical conditions, older age, lower socio-economic status, unrealistic expectations and inappropriate use of the anti-impotence drugs. Cardiovascular side effects and cost were two most important drug barriers.

CONCLUSIONThe factors influencing the management of ED among the general practitioners were multiple and complex. An adequate understanding of how these factors (doctors, patients and drugs) interact can assist in the formulation and implementation of strategies that encourage GPs to identify and manage ED patients.

INTRODUCTION: The cost-effectiveness of screening asymptomatic non-alcoholic fatty liver disease (NAFLD) patients remains debatable, with current studies assuming lifelong benefits of NAFLD screening while neglecting cardiovascular outcomes. This study aims to assess the cost-effectiveness of NAFLD screening among type 2 diabetes mellitus (T2DM) patients, and to establish a price threshold for NAFLD treatment, when it becomes available. METHOD: A Markov model was constructed comparing 4 screening strategies (versus no screening) to identify NAFLD with advanced fibrosis among T2DM patients: fibrosis-4 (FIB-4), vibration-controlled transient elastography (VCTE), FIB-4 and VCTE (simultaneous), and FIB-4 and VCTE (sequential). Sensitivity analyses and price threshold analyses were performed to assess parameter uncertainties in the results. RESULTS: VCTE was the most cost-effective NAFLD screening strategy (USD24,727/quality-adjusted life year [QALY]), followed by FIB-4 (USD36,800/QALY), when compared to no screening. Probabilistic sensitivity analysis revealed a higher degree of certainty for VCTE as a cost-effective strategy compared to FIB-4 (90.7% versus 73.2%). The duration of expected screening benefit is the most influential variable based on incremental cost-effectiveness ratio tornado analysis. The minimum duration of screening benefit for NAFLD screening to be cost-effective was at least 2.6 years. The annual cost of NAFLD treatment should be less than USD751 for NAFLD screening to be cost-effective. CONCLUSION Both VCTE and FIB-4 are cost-effective NAFLD screening strategies among T2DM patients in Singapore. However, given the lack of access to VCTE at primacy care and potential budget constraints, FIB-4 can also be considered for NAFLD screening among T2DM patients in Singapore.

INTRODUCTIONAcute respiratory infections are prevalent and pose a constant threat to society. While the use of facemasks has proven to be an effective barrier to curb the aerosol spread of such diseases, its use in the local community is uncommon, resulting in doubts being cast on its effectiveness in preventing airborne infections during epidemics. We thus aimed to conduct a literature review to determine the factors that influence the use of facemasks as a primary preventive health measure in the community.

METHODSA search for publications relating to facemask usage was performed on Medline, PubMed, Google, World Health Organization and Singapore government agencies' websites, using search terms such as 'facemask', 'mask', 'influenza', 'respiratory infection', 'personal protective equipment', 'disease prevention', 'compliance' and 'adherence'. Findings were framed under five components of the Health Belief Model: perceived susceptibility, perceived benefits, perceived severity, perceived barriers and cues to action.

RESULTSWe found that individuals are more likely to wear facemasks due to the perceived susceptibility and perceived severity of being afflicted with life-threatening diseases. Although perceived susceptibility appeared to be the most significant factor determining compliance, perceived benefits of mask-wearing was found to have significant effects on mask-wearing compliance as well. Perceived barriers include experience or perception of personal discomfort and sense of embarrassment. Media blitz and public health promotion activities supported by government agencies provide cues to increase the public's usage of facemasks.

CONCLUSIONComplex interventions that use multipronged approaches targeting the five components of the Health Belief Model, especially perceived susceptibility, are needed to increase the use of facemasks in the community. Further studies are required to evaluate the effectiveness of implemented interventions.

INTRODUCTIONNot much is known regarding how primary care physicians (PCPs) in Singapore keep themselves healthy and mitigate ill health. This study aims to determine the health-seeking behaviour of local PCPs and to identify the predictors of local PCPs attaining the recommended level of exercise.

METHODSThis study was a cross-sectional questionnaire survey, which included questions on the demographic characteristics, practice profiles and health-seeking behaviour of PCPs. The sampling frame was the 1,400 listed members of the College of Family Physicians Singapore. The anonymised survey was executed in two phases: a postal survey, followed by a web-based survey on the College of Family Physicians Singapore website. The two data sets were collated; the categorical variables, summarised; and the differences between subgroups (based on exercise engagement), compared using Fisher's exact test. The effect of each risk factor on exercise duration was quantified using odds ratio (OR) estimate and 95% confidence interval (CI). Multivariate logistic regression analysis was performed to identify significant predictors of exercise engagement.

RESULTSA total of 631 PCPs participated in the survey--26% were ≤ 34 years old, 58% were male, 21% were single, 34% were singleton practitioners, and 56% were private practitioners. The percentage of PCPs who exercised ≥ 2.5 hours weekly was 29%, while 28% exercised < 0.5 hours weekly. Of the PCPs surveyed, 1% currently smoke, 0.8% drink more than 14 units of alcohol weekly, 60% undertook health screening, 65% had blood investigations done, and 64% had taken preventive measures such as getting influenza vaccination.

CONCLUSIONWhile local PCPs generally did not have undesirable habits such as smoking and alcohol abuse, they could further increase their exercise intensity and undertake more preventive measures such as getting vaccinated against various diseases.
