Background: Many smokers have undiagnosed chronic obstructive pulmonary disease (COPD), and yet screening for COPD is not recommended. Smokers who know that they have airflow limitation are more likely to quit smoking. This study aims to identify the prevalence and predictors of airflow limitation among smokers in primary care.
Methods: Current smokers ≥ 40 years old who were asymptomatic clinic attendees in a primary care setting were recruited consecutively for two months. We used a two-step strategy. Step 1: participants filled in a questionnaire. Step 2: Assessment of airflow limitation using a pocket spirometer. Multiple logistic regression was utilised to determine the best risk predictors for airflow limitation.
Results: Three hundred participants were recruited. Mean age was 58.35 (SD 10.30) years old and mean smoking history was 34.56 pack-years (SD 25.23). One in two smokers were found to have airflow limitation; the predictors were Indian ethnicity, prolonged smoking pack-year history and Lung Function Questionnaire score ≤ 18. Readiness to quit smoking and the awareness of COPD were low.
Conclusions: The high prevalence of airflow limitation and low readiness to quit smoking imply urgency with helping smokers to quit smoking. Identifying airflow limitation as an additional motivator for smoking cessation intervention may be considered. A two-step case-finding method is potentially feasible.

Muslim consumers have special needs in medical treatment that differ from non-Muslim consumers. In particular, there is a growing demand among Muslim consumers for Halal medications. This descriptive exploratory study aims to determine the Halal status of selected cardiovascular, endocrine, and respiratory medications stored in an out-patient pharmacy in a Malaysian governmental hospital. Sources of active ingredients and excipients for each product were assessed for Halal status based on available information obtained from product leaflets, the Medical Information Management System (MIMS) website, or manufacturers. Halal status was based on the products' sources and categorized into Halal, Mushbooh, or Haram. The proportions of Halal, Mushbooh, and Haram products were at 19.1%, 57.1%, and 23.8%, respectively. The percentage of active ingredients for cardiovascular/endocrine products that were assessed as Haram was 5.3%; for respiratory medications, it was only 1.1%. For excipients, 1.7% and 4.8% fall under the category of Haram for cardiovascular/endocrine products and respiratory products, respectively. Ethanol and magnesium stearate were found to be the common substances that were categorized as Haram and Mushbooh.
RATIONALE, AIMS AND OBJECTIVES: To evaluate the impact of clinical audit on diabetes care provided to type 2 diabetic patients attending our hospital general medical clinics.
METHODS: Performances on diabetes-related process measures and intermediate outcome measures were evaluated through structured review of outpatient medical records. The results were fed back to the doctors and measures were implemented to improve care. The performance indicators were re-evaluated 2 years later to complete the audit cycle.
RESULTS: Annual testing rates improved for HbA1c (68.4% vs. 87.4%; P < 0.001) and lipid profile (91.8% vs. 97%; P = 0.027). Enquiry on smoking improved from 45.9% to 82.3% (P < 0.001), eye screening rates from 68.9% to 78.8% (P = 0.020) and foot examinations from 22.4% to 64.1% (P < 0.001). Prescription rates for insulin increased from 17.3% to 31.8% (P = 0.001) and statin from 83.2% to 94.4% (P < 0.001). The use of aspirin (80.6% vs. 83.8%; P =0.402) and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (92.3% vs. 88.9%; P = 0.239) remained high in both cycles. More patients achieved targets for HbA1c < 7% (38% vs. 26%; P = 0.006), blood pressure < 130/80 mmHg (43% vs. 32%; P = 0.071) and low-density lipoprotein cholesterol < 2.6 mmol/L (71% vs. 52%; P <0.001).
CONCLUSION: Clinical audit is a useful tool in improving diabetes care.

We audited the standard of care provided to 200 consecutive type 2 diabetic patients attending our hospital general medical clinic. Data on diabetes related processes and outcome measures were collected. Annual testing rates (blood pressure 100%, fasting lipid profile 91.8%, HbA1c 69%) were higher compared to complications screening rates (Eye 69%, albuminuria 51%, foot 22.4%). Lifestyle intervention was lacking with BMI documented in 38.3% of patients and smoking history in 46%. Fifty percent and 41% of patients with HbA1c > 7.5% were referred to diabetes educator and dietitian respectively. For outcome measures, 26% of patients achieved HbA1c < or = 7%, 33% achieved BP < or = 130/80 while 56% achieved LDL < or = 2.6 mmol/L. Aspirin was prescribed in 78% and ACE inhibitor or angiotensin receptor blocker in 91.8% of patients. Lifestyle intervention and complication screening are the two major areas of deficiencies in the care of type 2 diabetic patients in our hospital general medical clinic.

In the Malaysian setting of multi-ethnicity and high BCG coverage, interpretation of Tuberculin Skin Testing (TST) may be difficult. Between January 2001 and December 2003, a retrospective study on all adult patients with documented TST results treated for tuberculosis (TB) in chest clinics of two government hospitals was conducted to determine the reliability of TST and factors affecting its interpretation. One hundred and three patients [mean age (SD): 43 (17); male: 67%] were eligible for data collection: 72% and 57% of patients had positive TST results based on cut-off points of 10mm and 15mm respectively. The only significant univariate association with TST results was the severity of co-morbidity. A patient with co-morbidity score of 3 defined as those with any cancer, end-stage renal or liver disease, or HIV disease, was more likely to have a negative TST results [10mm cut-off point: Odd Ratio (95% CI) 6.6 (1.82 to 24.35), p = 0.003; 15mm cut-off point: 4.8 (1.21 to 18.95), p = 0.012]. A TST reading of 10mm had a higher sensitivity than 15mm as the cut-off point in diagnosing TB infection. Considering all possible confounding factors like ethnicity, prior BCG vaccination and TB burden in the population, severity of co-morbidity remains strongly predictive of a negative TST. Caution should be exercised in interpreting TST in these patients.

The results of a prospective study of 94 patients with history of ear, nose or aerodigestive tract foreign bodies were analysed. Sixty six to 94% of patients presented within 24 hours to a primary care doctor, 80 to 94% was referred to the ENT Department within 24 hours and 89 to 93% of patients had their foreign bodies removed within 24 hours. Overall, 58% of aural foreign bodies, 67% nasal foreign bodies and 94% of aerodigestive tract foreign bodies were removed within 48 hours of insertion. As a result of the prompt removal of foreign bodies in the majority of patients, no significant complications occurred. Foreign bodies in the aerodigestive tract tend to present earlier and more promptly removed compared with ear and nose foreign bodies. There was a significantly higher proportion of foreign body in the right ear and nostril compared to the left.
Background Detecting errors before medication dispensed or 'near misses' is a crucial step to combat the incidence of dispensing error. Despite this, no published evidence available in Malaysia relating to these issues. Objective To determine the incidence of medication labeling and filling errors, frequency of each type of the errors and frequency of the contributing factors at the final stage before dispensing. Setting Six Penang public funded hospitals outpatient pharmacies. Methods A prospective multicentre study, over 8 week's period. Pharmacists identified and recorded the details of either medication labeling and/or filling error at the final stage of counter-checking before dispensing. Besides, the contributing factors for each error were determined and recorded in data collection form. Descriptive analysis was used to explain the study data. Main outcome measure The incidence of near misses. Results A total of 187 errors (near misses) detected, with 59.4% (n = 111) were medication filling errors and 40.6% (n = 76) were labeling errors. Wrong drug (n = 44, 39.6%) was identified as the highest type of filling errors while incorrect dose (n = 34, 44.7%) was identified as the highest type of labeling errors. Distracted and interrupted work environment was reported to lead the highest labeling and filling errors, followed by lack of knowledge and skills for filling errors and high workload for labeling errors. Conclusion The occurrence of near misses related to medication filling and labelling errors is substantial at outpatient pharmacy in Penang public funded hospitals. Further research is warranted to evaluate the intervention strategies needed to reduce the near misses.
Background Prescribing errors in children are common due to individualization of dosage regimen. It potentially has a great impact especially in this vulnerable population. Objective To determine the prevalence and common types of prescribing errors in a Malaysian pediatric outpatient department and to determine the factors contributing to prescribing errors. Setting Pediatric Outpatient Department and Outpatient Pharmacy at a tertiary care hospital in Malaysia. Method This is a prospective, cross sectional observational study where all new prescriptions received by the outpatient pharmacy from patients attending pediatric out-patient clinic were included for analysis. Descriptive statistics and logistic regression were used to analyze the data. Main outcome measure Frequency, types, potential clinical consequences and contributing factors of prescribing errors. Results Two hundred and fifty new prescriptions with 493 items were analyzed. There were 13 per 100 prescriptions with at least one prescribing error and 7.3% of the total items were prescribed incorrectly. The most common types of prescribing error were, an ambiguous prescription (61.1%) followed by an unrecommended dose regimen (13.9%). Logistic regression analysis showed that the risk of a prescribing error significantly increased when the prescription was written by a house officer (OR 4.72, p = 0.029). Errors were judged to be potentially non-significant (33.3%), significant (36.1%), or serious (30.6%). Conclusion The experience of prescribers is an important factor that contributes to prescribing errors in pediatrics. Many of the errors made were potentially serious and may impact on the patients' well-being.
Three hundred thirty-one consecutive patients presenting with hypertension to the outpatient medical clinic of Tengku Ampuan Afzan Hospital, Kuantan, Malaysia were screened and 150 patients with concurrent diabetes were enrolled into a cross-sectional study. The majority of patients were male (60.6%) with a mean age of 60.0 +/- 11.0 years. The mean systolic blood pressure (SBP) was 140.9 +/- 20.1 mmHg and the mean diastolic blood pressure (DBP) was 81.7 +/- 9.8 mmHg. Only 38.0% (57/150) of patients had blood pressures within recommended guidelines (130/80 mmHg). The mean blood pressure in this group was 123.7 +/- 8.5/76.4 +/- 5.6 mmHg. The majority of patients were on either 2 (41.3%) or 3 (31.3%) anti-hypertensives. Females had a significantly higher SBP 145.4 +/- 22.7 vs. 138.0 +/- 17.8 mmHg in males (p = 0.026). The level of blood pressure control in diabetics was unsatisfactory, especially in females and the elderly. A reassessment of priorities in the management of patients with concurrent hypertension and diabetes is therefore, urgently needed.

OBJECTIVES. Obesity is an issue of concern among patients with schizophrenia as it is a co-morbid condition that is closely related to metabolic syndrome. The present study assessed the correlation of body mass index with antipsychotic use among multiracial schizophrenia outpatients. The study also compared the patients' body mass index with Malaysian Adult Nutrition Survey (MANS) data.
METHODS. A total of 216 participants were recruited into a cross-sectional study conducted over 5 months, from December 2010 to April 2011. Body weight and height were measured using the standard methods. Demographic data and treatment variables were gathered through interview or review of the medical records.
RESULTS. There were differences in mean body mass index between men and women (p = 0.02) and between Malay, Chinese and Indian races (p = 0.04). Stratified by sex, age, and race, the body mass index distributions of the patients were significantly different to those of the reference MANS population. The prevalence of obesity among patients was more than 2-fold greater than among the reference population in all variables. Although body mass index distribution was related to antipsychotic drugs (χ(2) = 33.42; p = 0.04), obesity could not be attributed to any specific drug.
CONCLUSION. The prevalence of obesity among patients with schizophrenia was significantly greater than that in the healthy Malaysian population, and affects the 3 main races in Malaysia.

BACKGROUND: There are currently limited data available on the patterns of opioid prescribing in Malaysia. This study investigated the patterns of opioid prescribing and characterized the dosing and duration of opioid use in patients with noncancer and cancer pain.
METHODS: This retrospective, cross-sectional study was conducted at an outpatient hospital setting in Malaysia. All prescriptions for opioids (dihydrocodeine, fentanyl, morphine, and oxycodone) issued between January 2013 and December 2014 were examined. The number of prescriptions and patients, the distribution of mean daily dose, annual total days covered with opioids, and annual total opioid dose at the individual level were calculated and stratified by noncancer and cancer groups.
RESULTS: A total of 1015 opioid prescriptions were prescribed for 347 patients from 2013 to 2014. Approximately 41.5% of patients (N = 144/347) and 58.5% (N = 203/347) were associated with noncancer and cancer diagnosis, respectively. Oxycodone (38.0%) was the highest prescribed primarily for the noncancer group. The majority of patients in both noncancer (74.3%) and cancer (60.4%) groups were receiving mean daily doses of < 50 mg morphine equivalents. The chronic use of opioids (> 90 days per year) was associated with 21.8% of patients in the noncancer group and 17.5% in the cancer group.
CONCLUSIONS: The finding from this study showed that 41.5% of opioid users at an outpatient hospital setting in Malaysia received opioids for noncancer pain and 21.8% of these users were using opioids for longer than 90 days. The average daily dose in the majority of patients in both groups of noncancer and cancer was modest.

Background: Several studies have found that pharmacists can assist in screening and prevention of osteoporosis by referring patients for bone mineral density scans and counselling on lifestyle changes. In Malaysia, screening osteoporosis in all elderly women is not mandatory due to its cost. One approach to address this gap is to develop a pharmacist-led osteoporosis screening and prevention program. However, there is a paucity of data on the perspectives of Malaysian pharmacists in this area.
Objective: To explore the perspective of stakeholders (policy makers, doctors, pharmacists, nurses and patients) towards the role of pharmacists in osteoporosis screening and management.
Setting: A primary care clinic located within a teaching hospital in Kuala Lumpur, Malaysia.
Method: Patients (n = 20), nurses (n = 10), pharmacists (n = 11), doctors (n = 10) and policy makers (n = 5) were individually interviewed using a semi-structured topic guide. Purposive sampling was used. Interviews were transcribed verbatim and analysed using thematic analysis. Main outcome measure Perspective of stakeholders on the current and future role of pharmacists.
Results: All participants perceived pharmacists to be suppliers of medication, although there was some recognition of roles in providing medication advice. Nonetheless, these stakeholders were eager for pharmacists to expand their non-dispensing roles towards counselling, creating awareness and screening of osteoporosis. Interviewed pharmacists referred to their current role as 'robotic dispensers' and unanimously agreed to spread out to osteoporosis management role.
Conclusion: Under stakeholders there is a willingness to expand the role of pharmacists in Malaysia to non-dispensing roles, particularly in osteoporosis screening and management.

BACKGROUND: Methadone is a substrate of the permeability glycoprotein (P-gp) efflux transporter, which is encoded by the ABCB1 (MDR1) gene. Large interindividual variability in serum methadone levels for therapeutic response has been reported. Genetic variations in ABCB1 gene may be responsible for the variability in observed methadone concentrations.
OBJECTIVE: This study investigated the associations of ABCB1 polymorphisms and serum methadone concentration over the 24-hour dosing interval in opioid-dependent patients on methadone maintenance therapy (MMT).
METHODS: One hundred and forty-eight male opioid-dependent patients receiving MMT were recruited. Genomic deoxyribonucleic acid (DNA) was extracted from whole blood and genotyped for ABCB1 polymorphisms [i.e. 1236C>T (dbSNP rs1128503), 2677G>T/A (dbSNP rs2032582), and 3435C>T (dbSNP rs1045642)] using the allelic discrimination real-time polymerase chain reaction (PCR). Blood samples were collected at 0, 0.5, 1, 2, 4, 8, 12, and 24 hours after the dose. Serum methadone concentrations were measured using the Methadone ELISA Kit.
RESULTS: Our results revealed an association of CGC/TTT diplotype (1236C>T, 2677G>T/A, and 3435C>T) with dose-adjusted serum methadone concentration over the 24-hour dosing interval. Patients with CGC/TTT diplotype had 32.9% higher dose-adjusted serum methadone concentration over the 24-hour dosing interval when compared with those without the diplotype [mean (SD) = 8.12 (0.84) and 6.11 (0.41) ng ml-1mg-1, respectively; p = 0.033].
CONCLUSION: There was an association between the CGC/TTT diplotype of ABCB1 polymorphisms and serum methadone concentration over the 24-hour dosing interval among patients on MMT. Genotyping of ABCB1 among opioid-dependent patients on MMT may help individualize and optimize methadone substitution treatment.

Arterial hypertension (HPT) burden up to two third of systemic lupus erythematosus (SLE) patients and contributes to accelerated atherosclerosis and cardiovascular (CV) risk. We aim to determine the prevalence of HPT among lupus nephritis (LN) patients who were in complete remission (CR) for a minimum of 6 months, with estimated glomerular filtration rate (eGFR) of >60 mL/min/1.73 m(2). This is a cross-sectional study of 64 LN patients who attended Nephrology/SLE Clinic at The National University of Malaysia Medical Centre (UKMMC). Persistent hypertension (blood pressure (BP) ≥140/90 mmHg for at least two occasions), CR for a minimum of 6 months and eGFR of >60 mL/min/1.73 m(2) were identified. Univariate and multivariate analyses were performed to determine the demographic and disease characteristics associated with HPT. Thirty-four of them (53.1 %) were hypertensive. Persistent HPT was associated with disease duration, acute kidney injury and high BP at the onset of LN, longer duration interval to achieve CR, number of relapses and cyclosporine A (CyA) use. There were no associations between histological classes, nephrotic range proteinuria, body mass index and waist circumference with HPT. Factors independently associated with HPT were disease duration OR 1.06 [95 %CI (0.91-1.24)], longer duration interval to achieve CR OR 1.104 [95 %CI (1.02-1.19)], number of relapses OR 2.53 [95 % CI (1.01-6.3)] and CyA use OR 5.3 [95 % CI (1.14-23.9)]. The prevalence of HPT among LN is high despite in remission. Aggressive treatment is important to achieve early CR and to prevent relapses.

OBJECTIVES: There is a lack of local instruments to assess behavioural and psychological symptoms of dementia (BPSD). This 2-stage cross-sectional study was aimed at validating a Malay translated version of the Neuropsychiaric Inventory (MvNPI).
MATERIALS AND METHODS: It was conducted on a selected group of 138 elderly outpatients with dementia and their caregivers in Hospital Pulau Pinang. Severity of dementia was assessed using the Malay-translated version of Mini Mental State Examination (MMSE). The original NPI was translated and then back-translated before it was pilot-tested. The MvNPI was administered twice, a week apart on the same caregiver by the same investigator.
RESULTS: The individual items and total scale score of MvNPI had high internal consistency, with Corrected Item-Total Correlation ranging from satisfactory to good (0.41 to 0.77). The Cronbach's alpha for all the NPI domains showed high internal consistency (0.83), and subtotal for severity and distress scores were perfect (0.998 to 1.00). There was no significant difference between test-retest mean scores (p>0.05) and their correlations were perfect (0.996 to 1.00). Content validity indicated mild and inverse relationship between MMSE scores and severity, and distress score (-0.281 and -0.268, respectively, with p<0.001). Discriminant validity calculated using Mann-Whitney U test was found to be significant (p<0.001) in differentiating severity of cognitive impairment. Factor analysis revealed four possible components existed in MvNPI.
CONCLUSIONS: The MvNPI is a valid and reliable tool for assessing BPSD among Malay speaking populations of Malaysia and its neighbouring South East Asian countries.
Background: Diabetes mellitus is a lifelong chronic condition that requires self-management. Lifestyle modification and adherence to antidiabetes medications are the major determinants of therapeutic success in the management of diabetes.
Purpose: To assess the effects of a pharmaceutical care (PC) model on medication adherence and glycemic levels of people with type 2 diabetes mellitus.
Patients and methods: A total of 241 people with type 2 diabetes were recruited from a major teaching hospital in Malaysia and allocated at random to the control (n=121) or intervention (n=120) groups. Participants in the intervention group received PC from an experienced pharmacist, whereas those in the control group were provided the standard pharmacy service. Medication adherence was assessed using the Malaysian Medication Adherence Scale, and glycemic levels (glycated hemoglobin values and fasting blood glucose [FBG]) of participants were obtained at baseline and after 4, 8, and 12 months.
Results: At baseline, there were no significant differences in demographic data, medication adherence, and glycemic levels between participants in the control and intervention groups. However, statistically significant differences in FBG and glycated hemoglobin values were observed between the control and intervention groups at months 4, 8, and 12 after the provision of PC (median FBG, 9.0 versus 7.2 mmol/L [P<0.001]; median glycated hemoglobin level, 9.1% versus 8.0% [P0.001] at 12 months). Medication adherence was also significantly associated with the provision of PC, with a higher proportion in the intervention group than in the control group achieving it (75.0% versus 58.7%; P=0.007).
Conclusion: The provision of PC has positive effects on medication adherence as well as the glycemic control of people with type 2 diabetes. Therefore, the PC model used in this study should be duplicated in other health care settings for the benefit of more patients with type 2 diabetes.

Objective: Adherence to medication is essential for maximising the outcomes of patients with schizophrenia as the consequences of poor adherence are devastating. The study aimed to compare medication adherence between patients with relapse schizophrenia and those attending psychiatric follow-up clinics, and to determine the factors affecting adherence.
Methods: This was a cross-sectional study involving 70 patients with schizophrenia who were divided equally into 2 groups. Medication adherence was assessed with the Medication Adherence Rating Scale. Appropriate instruments were used to measure insight, social support, and psychopathology. Various socio-demographic and clinical variables were explored to find associations with medication adherence.
Results: Medication adherence among patients with schizophrenia was poor; 51% of the patients did not adhere to a medication regimen. Adherence was better in outpatients with schizophrenia (61%) than in relapse cases (39%), although the difference was not statistically significant (t = 1.70; p = 0.09). Besides, relapse patients had significant higher number of admission (X2 = 22.95; p < 0.05) and severe psychopathology (t = –29.96; p < 0.05), while perceived social support was significantly better in outpatients with schizophrenia (t = 2.90; p < 0.05). Frequency of admission (adjusted b = –0.55; 95% confidence interval [CI], -0.99 to -0.10; p < 0.05) and psychopathology (adjusted b = –0.12; 95% CI, -0.24 to -0.01; p < 0.05) were also significantly associated with medication adherence.
Conclusion: Medication adherence among both groups of patients with schizophrenia was poor. If adherence is addressed appropriately, the number of admissions and severity of psychopathology could be improved.

The purpose of this study was to compare the serum interleukin (IL)-23 levels between rheumatoid arthritis (RA) patients and healthy controls and to determine the correlation of IL-23 levels with disease activity, joint damage and functional disability in RA. Serum samples were obtained from 45 patients with RA and 45 healthy controls. The enzyme-linked immunosorbent assay method was used for quantitative analysis of IL-23. All the RA patients were assessed for disease activity based on the 28-joint disease activity score, joint damage based on modified Sharp score, and functional ability using the Health Assessment Questionnaire-Disability Index. The mean serum IL-23 level was much higher among the RA patients (24.50 ± 13.98 pg/mL) compared to the controls (5.98 ± 3.40 pg/mL; p < 0.01). There was a significant positive relationship between IL-23 levels and disease activity and questionnaire scores (p = 0.003 and 0.020, respectively). On logistic regression analysis, IL-23 levels were significantly higher in patients with moderate to high disease activity (p = 0.008, odds ratio = 1.073, 95% confidence interval = 1.019-1.130) and patients with significant functional disability (p = 0.008, odds ratio = 1.085, 95% confidence interval = 1.021-1.153). RA patients have significantly higher levels of serum IL-23. The IL-23 levels correlate well with disease activity and functional disability but not with radiographic joint damage.
