Cost-effectiveness of and satisfaction with a Helicobacter pylori “test and treat” strategy compared with prompt endoscopy in young Asians with dyspepsia

Objective: To compare a Helicobacter pylori “test and treat” strategy with prompt endoscopy in young Asians with dyspepsia. Methods: A randomised, prospective study was carried out on uninvestigated dyspeptics aged <45 years in a single (academic) primary care centre. Patients were randomised to either a [13C]urea breath test (UBT) or prompt endoscopy (oesophagogastroduodenoscopy (OGD) and followed-up for 12 months. Results: 432 patients (mean (SD) age 30 (8) years, male 46%, ethnicity: Malays 33.3%, Chinese 30.6%, Indians 34.7%) were randomised to UBT (n = 222) or OGD (n = 210). 387 (89.6%) patients completed the study. At 12 months, there was no difference in symptom change (measured by the Leeds Dyspepsia Questionnaire) between the two groups, but more patients were very satisfied (40.0% vs 21.6%, p<0.0001) in the OGD group. More additional endoscopy was performed in the UBT group (25 vs 10, p = 0.03), but medication consumption was higher in the OGD group (proton pump inhibitor 3.6 (8.8) vs 2.0 (7.5) weeks, p<0.001; H2 receptor antagonist 5.3 (9.7) vs 3.9 (9.2) weeks, p = 0.017; prokinetics 1.4 (4.7) vs 0.4 (2.5) weeks, p<0.001) and no differences in medical consultation were noted. The median cost of the initial prompt endoscopy approach at 12 months was significantly higher than a “test and treat” strategy (US

Antibiotic prescribing for childhood febrile illness by primary care doctors in Malaysia

BackgroundChronic Obstructive Pulmonary Disease (COPD) is a chronic disease with repeated exacerbations resulting in gradual debilitation. The quality of life has been shown to be poor in patients with COPD despite efforts to improve self-management. However, the evidence on the benefit of self-management in COPD is conflicting. Whether this could be due to other unmet needs of patients have not been investigated. Therefore, we aimed to explore unmet needs of patients from both patients and doctors managing COPD.MethodsWe conducted a qualitative study with doctors and patients in Malaysia. We used convenience sampling to recruit patients until data saturation. Eighteen patients and eighteen doctors consented and were interviewed using a semi-structured interview guide. The interviews were audio-recorded, transcribed verbatim and checked by the interviewers. Data were analysed using a thematic approach.ResultsThe themes were similar for both the patients and doctors. Three main themes emerged: knowledge and awareness of COPD, psychosocial and physical impact of COPD and the utility of self-management. Knowledge about COPD was generally poor. Patients were not familiar with the term chronic obstructive pulmonary disease or COPD. The word ‘asthma’ was used synonymously with COPD by both patients and doctors. Most patients experienced difficulties in their psychosocial and physical functions such as breathlessness, fear and helplessness. Most patients were not confident in self-managing their illness and prefer a more passive role with doctors directing their care.ConclusionsIn conclusion, our study showed that knowledge of COPD is generally poor. There was mislabelling of COPD as asthma by both patients and physicians. This could have resulted in the lack of understanding of treatment options, outcomes, and prognosis of COPD. The misconception that cough due to COPD was contagious, and breathlessness that resulted from COPD, had important physical and psychosocial impact, and could lead to social isolation. Most patients and physicians did not favour self-management approaches, suggesting innovations based on self-management may be of limited benefit.

Healthcare Professionals’ and Policy Makers’ Views on Implementing a Clinical Practice Guideline of Hypertension Management: A Qualitative Study

Objective This study aims to examine the validity of the Framingham general cardiovascular disease (CVD) risk chart in a primary care setting. Design This is a 10-year retrospective cohort study. Setting A primary care clinic in a teaching hospital in Malaysia. Participants 967 patients’ records were randomly selected from patients who were attending follow-up in the clinic. Main outcome measures Baseline demographic data, history of diabetes and smoking, blood pressure (BP), and serum lipids were captured from patient records in 1998. Each patients Framingham CVD score was computed from these parameters. All atherosclerotic CVD events occurring between 1998 and 2007 were counted. Results In 1998, mean age was 57 years with 33.8% men, 6.1% smokers, 43.3% diabetics and 59.7% hypertensive. Median BP was 140/80 mm Hg and total cholesterol 6.0 mmol/L (1.3). The predicted median Framingham general CVD risk score for the study population was 21.5% (IQR 1.2–30.0) while the actual CVD events that occurred in the 10 years was 13.1% (127/967). The median CVD points for men was 30.0, giving them a CVD risk of more than 30%; for women it is 18.5, a CVD risk of 21.5%. Our study found that the Framingham general CVD risk score to have moderate discrimination with an area under the receiver operating characteristic curve (AUC) of 0.63. It also discriminates well for Malay (AUC 0.65, p=0.01), Chinese (AUC 0.60, p=0.03), and Indians (AUC 0.65, p=0.001). There was good calibration with Hosmer-Lemeshow test χ2=3.25, p=0.78. Conclusions Taking into account that this cohort of patients were already on treatment, the Framingham General CVD Risk Prediction Score predicts fairly accurately for men and overestimates somewhat for women. In the absence of local risk prediction charts, the Framingham general CVD risk prediction chart is a reasonable alternative for use in a multiethnic group in a primary care setting.

Social Support and Glycemic Control in Adult Patients With Type 2 Diabetes Mellitus

Aim:  Fever in children, a mostly benign and self‐limiting illness, is often viewed with consternation by the care givers. It results in early consultation and excessive use of antipyretics and antibiotics. In this study, we document the prescribing practice of doctors from three primary care settings in Malaysia and identify the predictors of antibiotic prescription.

Awareness and Prevalence of Mammography Screening and its Predictors - A Cross Sectional Study in a Primary Care Clinic in Malaysia

Introduction Most studies have reported barriers to guideline usage mainly from doctors’ perspective; few have reported the perspective of other stakeholders. This study aimed to determine the views and barriers to adherence of a national clinical practice guideline (CPG) on management of hypertension from the perspectives of policymakers, doctors and allied healthcare professionals. Methods This study used a qualitative approach with purposive sampling. Seven in depth interviews and six focus group discussions were conducted with 35 healthcare professionals (policy makers, doctors, pharmacists and nurses) at a teaching hospital in Kuala Lumpur, Malaysia, between February and June 2013. All interviews were audio-recorded, transcribed verbatim and checked. Thematic approach was used to analyse the data. Results Two main themes and three sub-themes emerged from this study. The main themes were (1) variation in the use of CPG and (2) barriers to adherence to CPG. The three sub-themes for barriers were issues inherent to the CPG, systems and policy that is not supportive of CPG use, and attitudes and behaviour of stakeholders. The main users of the CPG were the primary care doctors. Pharmacists only partially use the guidelines, while nurses and policy makers were not using the CPG at all. Participants had suggested few strategies to improve usage and adherence to CPG. First, update the CPG regularly and keep its content simple with specific sections for allied health workers. Second, use technology to facilitate CPG accessibility and provide protected time for implementation of CPG recommendations. Third, incorporate local CPG in professional training, link CPG adherence to key performance indicators and provide incentives for its use. Conclusions Barriers to the use of CPG hypertension management span across all stakeholders. The development and implementation of CPG focused mainly on doctors with lack of involvement of other healthcare stakeholders. Guidelines should be made simple, current, reliable, accessible, inclusive of all stakeholders and with good policy support.

Transcultural Diabetes Nutrition Algorithm:A Malaysian Application

Introduction. The purpose of this study is to examine the prevalence of social support and its association with glycemic control in patients with type 2 diabetes mellitus (T2D) in an urban primary care center within an academic institution. Social support is important in the management of chronic diseases. However, its association with glycemic control has been controversial. Methods. This was part of a study examining religiosity in T2D patients. Nonsmoking patients with T2D for at least 3 years and aged 30 years and above were recruited. Social support was measured using The Social Support Survey–Medical Outcomes Study (SS), a self-administered questionnaire; the scores range from 19 to 95, and a high score indicates better social support. Glycemic control was measured using the 3 most recent glycosylated hemoglobin (HbA1c) levels within the past 3 years. Results. A total of 175 participants completed the SS survey (response rate 79.0%). The mean age was 62.7 (standard deviation [SD] = 10.8) years, and the mean duration of diabetes was 11.74 (SD = 6.7) years. The mean HbA1c level was 8.15 (SD = 1.44). The mean SS score was 68.1. The prevalence of high and low social support were 29.7% and 24.0 %, respectively. A significant correlation was found between SS score and number of social supporters (n = 167). No significant correlation was found between the self-reported number of social supporters or the SS score and the mean HbA1c level. Conclusions. Social support was not associated with glycemic control in adult patients with T2D in this primary care setting.

Lateral Flow Assay Based on Paper-Hydrogel Hybrid Material for Sensitive Point-of-Care Detection of Dengue Virus.

BACKGROUND Worldwide, over half a million women died of breast cancer in 2011 alone. Mammography screening is associated with a reduction of 20 to 35% in breast cancer mortality. The aim of this study was to determine the awareness and practice of mammography screening and predictors of its uptake in Malaysian women attending a primary care clinic. MATERIALS AND METHODS A cross-sectional study was carried out among women aged 40 to 74 years attending a primary care clinic in Selangor, Malaysia. An assisted structured questionnaire included questions on socio-demography, source of information and level of knowledge. An adapted version of the revised Champion Health Belief Model Scale plus other associated factors for mammography screening up-take were also included as part of the questionnaire. Predictors for mammography screening uptake were only determined in those who were aware about mammography screening. Significant predictors were determined by logistic regression. RESULTS 447 women were recruited for this study; 99.1% of them (n: 411) were aware about breast cancer. Only 50.1% (n: 206) had knowledge about mammography screening. Prevalence of clinical breast-examination (CBE) was 23.3% (n: 104) and mammography screening up-take was 13.2% (n: 59). The predictors for the latter were those who have had clinical breast-examination (aOR=17.58, 95%CI: 7.68-39.82) and those aged between 50 to 59 years (aOR=3.94, 95%CI: 1.61-9.66) as well as those aged 60 years and above (aOR=6.91, 95%CI: 2.28-20.94). Good knowledge and positive beliefs about mammography screening were not associated with mammography screening uptake. CONCLUSIONS Half of our Malaysian women were aware about mammography screening. However, the uptake of mammography was low. Previous CBE and older age were significant predictors of mammography screening uptake. Increasing CBE services may increase compliance with guidelines.

Detection of airflow limitation using a handheld spirometer in a primary care setting

Glycemic control among patients with prediabetes and type 2 diabetes mellitus (T2D) in Malaysia is suboptimal, especially after the continuous worsening over the past decade. Improved glycemic control may be achieved through a comprehensive management strategy that includes medical nutrition therapy (MNT). Evidence-based recommendations for diabetes-specific therapeutic diets are available internationally. However, Asian patients with T2D, including Malaysians, have unique disease characteristics and risk factors, as well as cultural and lifestyle dissimilarities, which may render international guidelines and recommendations less applicable and/or difficult to implement. With these thoughts in mind, a transcultural Diabetes Nutrition Algorithm (tDNA) was developed by an international task force of diabetes and nutrition experts through the restructuring of international guidelines for the nutritional management of prediabetes and T2D to account for cultural differences in lifestyle, diet, and genetic factors. The initial evidence-based global tDNA template was designed for simplicity, flexibility, and cultural modification. This paper reports the Malaysian adaptation of the tDNA, which takes into account the epidemiologic, physiologic, cultural, and lifestyle factors unique to Malaysia, as well as the local guidelines recommendations.
