    Objective: The aim of the study was to determine the early readmission rate among the psychiatric patients discharged from a teaching hospital in Malaysia. The associated factors were also examined. Methods: This is a prospective and observational study. The socio-demographic and clinical data of 202 patients from the psychiatric ward were collected on discharge along with the administration of instruments including Brief Psychiatric Rating Scale (BPRS), Life Events Questionnaire (LEQ), and Multidimensional Scale of Perceived Social Support (MSPSS). Assessment of compliance to medication and substance use was reliant on self-report data. Medication compliance was categorized as “poor” vs “good”, whereas poor compliance was the complete discontinuation of medication for at least two weeks. The patients were followed up to determine whether they were readmitted within 6 months. Results: At the end of 6 months follow-up, 32.2% of the subjects were readmitted. Univariate regression analysis indicated that patients with psychotic disorder, past episodes, previous admission, poor compliance, on conventional or depot injectable antipsychotic and higher BPRS scores on discharge were significantly associated with early readmission (p

    PIP: 40 experts representing Nepal, Malaysia, Thailand, Singapore, Korea, and the Philippines participated in a 3-day workshop in Manila in March 1976 for the purpose of discussing and proposing ways of dealing with the financial problems confronting the population programs of the individual countries. The Inter-Governmental Coordinating Committee for Southeast Asia Family/Population Planning sponsored the workshop. The recommendations made at the meeting were: 1) standardization of financing reporting procedures by the region's country programs on family planning; 2) closer coordination between donor agencies and policy-making bodies of country programs in the disbursement of funds; 3) frequent exchanges of experiences, ideas, technicaL knowledge, and other matters pertaining to the financial management of such programs; and 4) inclusion of applicable financial management topics in the training of clinical staffs and those involved in follow-up operations. Additionally, a proposal was made that national population organizations or committees develop research and evaluation units. Workshop discussion sessions focused on financial planning and management, accounting and disbursement of funds, use and control of foreign aid, cost of effectiveness and benefit analysis, and financial reporting.

    PURPOSE: This intervention was aimed to analyse the effect of academic writing and journal critiquing as educational approaches in improving critical thinking and collaborative learning among undergraduate medical students.

    METHODS: A research proposal writing format was created for the 4th year medical students of Melaka Manipal Medical College, Malaysia during their ophthalmology clinical postings. The students worked in small groups and developed research protocols through an evidence based approach. This was followed by writing reflective summaries in academic portfolios about the activity undertaken. A mixed methods study was designed to explore the possible role of collaborative research proposal writing in enhancing critical thinking and collaborative learning.

    RESULTS: Analysis of reflections submitted by 188 medical students after the intervention indicate that majority of them found an improvement in their skills of critical thinking and collaborative learning as a result of research protocol writing. All participants agreed that the model helped in applying concepts to new situations in the form of designing their own study, which reflected in enhanced higher order cognitive skills.

    CONCLUSION: This study shows that the introduction of a structured module in the core medical curriculum that focuses on research writing skills embedded with collaborative and reflective practices can enhance collaborative learning, critical thinking, and reasoning among medical students.

    Patients with chronic diseases such as diabetes, hypertension and cardiovascular diseases are known as
    high-risk groups for developing chronic kidney disease (CKD). Adequate related knowledge among them
    helps to increase their awareness towards CKD and adapt healthy attitude and practices for CKD
    prevention, which will result in better health outcomes. This study aimed to identify the patients'
    knowledge, attitude, and practices (KAP) towards the risks for CKD. This cross-sectional study used a selfadministered
    survey questionnaire on 103 adult male and female patients at four general surgical and
    medical wards in a teaching hospital using convenient sampling method. The data were computed using
    STATA version 12. Data on KAP were obtained through the Chronic Kidney Disease Screening Index
    questionnaire. The majority of respondents had poor knowledge (69.9%, n=72), but most of them had good
    attitude (68.9%, n=71) and good practices (88.3%, n=91) towards the risk of CKD. Significant associations
    were indicated between education level, occupation and monthly family income with knowledge (p-value <
    0.05). Significant associations were also indicated between age, sex, marital status and occupation with
    their attitude (p-value < 0.05). Meanwhile, marital status was found to be significantly associated with the
    practices towards the risk for CKD (p-value=0.008).
    Poor knowledge on the risk of getting CKD among hospitalized adults in this study implied the need for
    improvement in the public understanding towards the risk for CKD.

    Introduction: Second generation antipsychotic (SGA) was linked to increased risk of metabolic syndrome. The risk varies between different SGA. We aim to study this risk by examining the co-prescription of antihypertensive, antidiabetic and lipid lowering drugs in patients prescribed with either aripiprazole, quetiapine or clozapine.
    Methods: This is a retrospective cohort study based on the prescription records of a teaching hospital. Prescription records between January 1, 2013 and December 31, 2014 for
    psychiatric unit were extracted. Patients with at least one prescription of any antipsychotic were included. The odds of antihypertensive, antidiabetic and lipid lowering drugs co-prescription in patients with either aripiprazole, quetiapine or clozapine were calculated.
    Results: Of the 1742 study subjects, 88 patients were prescribed with aripiprazole, 175 patients with clozapine and 124 patients with quetiapine. Patients prescribed with quetiapine had
    higher odds of co-prescribed with antihypertensive (OR = 1.71, 95% CI = 1.11, 2.63), antidiabetic drugs (OR = 1.81, 95% CI = 1.11, 2.95) and lipid lowering drugs (OR = 1.94, 95% CI = 1.19, 3.16). There were higher odds of co-prescription of antihypertensive (OR = 1.54, 95% CI = 1.05, 2.25), antidiabetic drugs (OR = 1.69, 95% CI = 1.10, 2.59) and lipid lowering drugs
    (OR = 1.90, 95% CI = 1.24, 2.91) in patients with clozapine. However, there were no increase odds of co-prescription of the three agents in patients with aripiprazole.
    Conclusion: We need to monitor the risk of metabolic syndrome in patients treated with SGA. Aripiprazole has lower risk of metabolic syndrome.

    The aim of the present systematic review was to evaluate the effectiveness of technology-enhanced learning (TEL) in the field of Endodontics to improve educational outcomes compared to traditional learning methods. Randomized controlled studies published in English were identified from two electronic databases (PubMed and Scopus) up to May 2018. Two authors independently performed study selection, data extraction and assessed the risk of bias (ROB). Any teaching method using TEL was considered as the intervention, and this was compared to traditional methods. The outcome measuring the effectiveness of learning activities was evaluated by Kirkpatrick's four-level training evaluation model. The four levels of training outcomes are as follows: Reaction, Learning, Behaviour and Results. A meta-analysis was performed to estimate the standardized mean difference (SMD) by the random effects model. In total, 13 studies were included in the systematic review. Only three studies were assessed as 'low' ROB. A meta-analysis could not be performed in the domains of Reaction and Behaviour. No significant difference was observed in knowledge gain (Learning domain) between TEL and traditional methods (SMD, 0.14 (95% CI -0.10 to 0.39) I2  = 62.7%). Similarly, no difference was observed in performance (Behaviour domain). A variable response was found in attitude (Reaction domain). From the available evidence, it can be concluded that TEL is equally as effective as traditional learning methods.

    BACKGROUND: Blended learning (BL) is a learning innovation that applies the concept of face-to-face learning and online learning. However, examples of these innovations are still limited in the teaching of postgraduate education within the field of family medicine. Malaysian postgraduate clinical training, is an in-service training experience and face-to-face teaching with the faculty members can be challenging. Given this, we took the opportunity to apply BL in their training. This study provides an exploration of the perceptions of the educators and students toward the implementation of BL.

    METHODS: A qualitative approach was employed using focus group discussions (FGD) and in-depth interviews (IDI) at an academic centre that trains family physicians. Twelve trainees, all of whom were in their hospital specialty's rotations and five faculty members were purposively selected. Three FGDs among the trainees, one FGD and two IDIs among the faculty members were conducted using a semi-structured topic guide. Data were collected through audio-recorded interviews, transcribed verbatim and checked for accuracy. A thematic approach was used to analyse the data.

    RESULTS: There were four main themes that emerged from the analysis. Both educators and trainees bill the perspective that BL encouraged continuity in learning. They agreed that BL bridges the gap in student-teacher interactions. Although educators perceived that BL is in concordance with trainees learning style, trainees felt differently about this. Some educators and trainees perceived BL to be an extra burden in teaching and learning.

    CONCLUSION: This study highlights a mix positive and negative perceptions of BL by educators and trainees. BL were perceived positively for continuity in learning and student-teacher interaction. However, educator and learner have mismatched perception of learning style. BL was also perceived to cause extra burden to both educators and learners. Integrating BL to a traditional learning curriculum is still a challenge. By knowing the strengths of BL in this setting, family medicine trainees in Malaysia can use it to enhance their current learning experience. Future study can investigate different pedagogical designs that suit family medicine trainees and educators in promoting independent learning in postgraduate training.

    BACKGROUND: Effective pain management involves a cycle of continual pain assessment, good pain control strategies, and assessment of a standard quality improvement measures. A validated questionnaire that focuses on the quality of postoperative pain management in pediatric surgical patients and parental satisfaction on pain treatment is lacking. We, therefore, modified the revised American Pain Society Patient Outcome Questionnaire to evaluate the quality of postoperative pain management in a pediatric surgical setting. The primary aim of this study was to validate the modified version of revised American Pain Society Patient Outcome Questionnaire.

    METHODS: Parents whose children aged below 12 years and were scheduled for elective surgery in a teaching hospital, were approached to participate in this survey. The reliability of the modified version of revised American Pain Society Patient Outcome Questionnaire was evaluated using Cronbach's alpha test, while the construct validity was assessed with a principal component analysis using a varimax rotation. The parental satisfaction with pain treatment received was measured.

    RESULTS: A total of 108 parents completed the questionnaire. The internal consistency of the questionnaire shows a Cronbach's alpha of 0.798. Principal component analysis revealed a four-factor structure of the 12 items which explained 69.7% of the total variance. The factors are "Interference of sleep and activity," "Pain severity and drowsiness," "Perception of care," and "Adverse effects," respectively. Our study showed that this questionnaire is a valid and reliable measure for "Interference of sleep and activity" and "Pain severity and drowsiness" factors, but not for "Perception of care" and "Adverse effects." The results for "Perception of care" and "Adverse effects," therefore, should be reported as individual items instead of total score. The parental satisfaction with pain treatment given was good (median 8.0; IQR 3.0).

    CONCLUSION: The modified version of revised American Pain Society Patient Outcome Questionnaire is a feasible and easy instrument to administer. The questionnaire can be used to obtain feedback from parents about the outcomes and experiences of pain management and is helpful in continuous quality evaluation and improvement in the postoperative care in a pediatric setting.

    BACKGROUND: Age is an established risk factor for poor outcomes in individuals with influenza-related illness, and data on its influence on clinical presentations and outcomes in the South-East Asian settings are scarce. The aim of this study was to determine the above among adults with influenza-related upper respiratory tract infection at a teaching hospital in Malaysia.

    METHODS: A retrospective case-note analysis was conducted on a cohort of 3935 patients attending primary care at the University Malaya Medical Centre, Malaysia from February 2012 till May 2014 with URTI symptoms. Demographics, clinical characteristics, medical and vaccination history were obtained from electronic medical records, and mortality data from the National Registration Department. Comparisons were made between those aged <25, ≥25 to <65 and ≥65 years.

    RESULTS: 470 (11.9%) had PCR-confirmed influenza virus infection. Six (1.3%) received prior influenza vaccination. Those aged ≥65 years were more likely to have ≥2 comorbidities (P

    Respiratory tract infections (RTIs), including pneumonia and pulmonary tuberculosis, are among the leading causes of death worldwide. The use of accurate diagnostic tests is crucial to initiate proper treatment and therapy to reduce the mortality rates for RTIs. A PCR assay for simultaneous detection of six respiratory bacteria: Haemophilus influenzae, Klebsiella pneumoniae, Mycobacterium tuberculosis, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus pneumoniae, was developed in our lab. The current study aimed to evaluate the performance of this assay along with the retrospective surveillance of respiratory pathogens at a teaching hospital in Kelantan, Malaysia. Leftover sputa (n = 200) from clinical laboratories were collected and undergone DNA template preparation for PCR analysis. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the PCR assay were determined in comparison with the gold standard sputum culture. Overall, the accuracy performance of this assay was 94.67% (95% CI: 90.87% to 97.21%) with sensitivity, specificity, PPV and NPV of 100%, 91.67%, 87.1% and 100%, respectively. Based on the organisms detected from sputa, K. pneumoniae ranked as the top isolate (n = 48), followed by P. aeruginosa (n = 13) and H. influenzae (n = 10). Surveillance among the patients showed that the associations of bacterial positive with gender and means of acquisition were found significant (p values = 0.049 and 0.001, respectively). Besides the promising performance of this ready-to-use molecular-based assay for the rapid detection of selected bacteria pathogens, this study also highlighted significant spread of K. pneumoniae RTIs in the community.

    OBJECTIVES: Flipped classroom (FC) is a pedagogical model to engage students in learning process by replacing the didactic lectures. Using technology, lectures are moved out of the classroom and delivered online as means to provide interaction and collaboration. Poll Everywhere is an audience response system (ARS) which can be used in an FC to make the activities more interesting, engaging, and interactive. This study aims to study the perception of undergraduate pharmacy students on FC activity using Poll Everywhere ARS and to study the effectiveness of FC activity as a teaching-learning tool for delivering complementary medicine module in the undergraduate pharmacy program.

    MATERIALS AND METHODS: In this nonrandomized trial on interrupted time series study, flipped class was conducted on group of 112 students of bachelor of pharmacy semester V. The topic selected was popular herbal remedies of the complementary medicine module. Flipped class was conducted with audio and video presentation in the form of a quiz using ten one-best-answer type of multiple-choice questions covering the learning objectives. Audience response was captured using web-based interaction with Poll Everywhere. Feedback was obtained from participants at the end of FC activity and debriefing was done.

    RESULTS: Randomly selected 112 complete responses were included in the final analysis. There were 47 (42%) male and 65 (58%) female respondents. The overall Cronbach's alpha of feedback questionnaire was 0.912. The central tendencies and dispersions of items in the questionnaire indicated the effectiveness of FC. The low or middle achievers of quiz session (pretest) during the FC activity were three times (95% confidence interval [CI] = 1.1-8.9) at the risk of providing neutral or negative feedback than high achievers (P = 0.040). Those who gave neutral or negative feedback on FC activity were 3.9 times (95% CI = 1.3-11.8) at the risk of becoming low or middle achievers during the end of semester examination (P = 0.013). The multivariate analysis of "Agree" or "Disagree" and "Agree" or "Strongly Agree" was statistically significant.

    CONCLUSION: This study provides insight on how the pharmacy students learn and develop their cognitive functions. The results revealed that the FC activity with Poll Everywhere is an effective teaching-learning method.

    INTRODUCTION: Beta-lactamase producing bacterial infection has been on surge due to selection pressure and injudicious antibiotics usage. Organisms that co-produced more than one beta lactamase enzyme posed diagnostic challenges which may result in inadequate treatment. To date, there is no standardised guideline offering phenotypic detection of AmpC β-lactamase. The purpose of this study was to determine the prevalence of ESBLs, AmpC β-lactamase and co-producer organisms in a teaching hospital.

    MATERIALS AND METHODS: Three hundred and four isolates of E. coli and Klebsiella sp. had been selected via convenient sampling. These isolates were identified using conventional laboratory methods and their antimicrobial susceptibilities were determined using disc diffusion method. Those isolates were then proceeded with ESBL confirmatory test, cloxacillin-containing Muller Hinton confirmatory test, modified double disk synergy test and AmpC disk test.

    RESULTS: Out of 304 isolates, 159 isolates were E. coli and 145 were Klebsiella sp. The prevalence of organisms which co-produced AmpC β-lactamase and ESBL enzymes were 3.0%. Besides that, 39 cefoxitin resistant and three cefoxitin susceptible isolates (13.8%) were proven to produce AmpC β-lactamase through AmpC disk test. Through the CLSI confirmatory test, 252 (82.9%) isolates were identified as ESBLs producers and the prevalence increased slightly when cloxacillin-containing Muller Hinton were used. Only three ESBLs positive organisms were positive for modified double disk synergy test.

    CONCLUSION: Distinguishing between AmpC β-lactamase and ESBL-producing organisms has epidemiological significance as well as therapeutic importance. Moreover, AmpC β-lactamase and ESBLs co-producing organisms can lead to false negative ESBL confirmatory test. Therefore, knowing the local prevalence can guide the clinician in navigating the treatment.

    Multidrug-resistant (MDR) Acinetobacter baumannii has increasingly emerged as an important nosocomial pathogen. The aim of this study was to determine the resistance profiles and genetic diversity in A. baumannii clinical isolates in a tertiary medical center in Malaysia. The minimum inhibitory concentrations of carbapenems (imipenem and meropenem), cephalosporins (ceftazidime and cefepime), and ciprofloxacin were determined by E-test. PCR and sequencing were carried out for the detection of antibiotic resistance genes and mutations. Clonal relatedness among A. baumannii isolates was determined by REP-PCR. Sequence-based typing of OXA-51 and multilocus sequence typing were performed. One hundred twenty-five of 162 (77.2%) A. baumannii isolates had MDR phenotype. From the 162 A. baumannii isolates, 20 strain types were identified and majority of A. baumannii isolates (66%, n = 107) were classified as strain type 1 and were positive for ISAba1-blaOXA-23and ISAba1-blaADCand had mutations in both gyrA and parC genes at positions, 83 and 80, resulting in serine-to-leucine conversion. REP-PCR analysis showed 129 REP types that generated 31 clones with a 90% similarity cutoff value. OXA-66 variant of the blaOXA-51-likegenes was predominantly detected among our A. baumannii clinical isolates belonging to ST195 (found in six clones: 1, 8, 9, 19, 27, and 30) and ST208 (found in clone 21). The study helps us in understanding the genetic diversity of A. baumannii isolates in our setting and confirms that international clone II is the most widely distributed clone in Universiti Kebangsaan Malaysia Medical Centre, Malaysia.

    This study aimed to develop an intervention to reduce medical errors and to determine if the intervention can reduce medical errors in public funded primary care clinics. A controlled interventional trial was conducted in 12 conveniently selected primary care clinics. Random samples of outpatient medical records were selected and reviewed by family physicians for documentation, diagnostic, and management errors at baseline and 3 months post intervention. The intervention package comprised educational training, structured process change, review methods, and patient education. A significant reduction was found in overall documentation error rates between intervention (Pre 98.3% [CI 97.1-99.6]; Post 76.1% [CI 68.1-84.1]) and control groups (Pre 97.4% [CI 95.1-99.8]; Post 89.5% [85.3-93.6]). Within the intervention group, overall management errors reduced from 54.0% (CI 49.9-58.0) to 36.6% (CI 30.2-43.1) and medication error from 43.2% (CI 39.2-47.1) to 25.2% (CI 19.9-30.5). This low-cost intervention was useful to reduce medical errors in resource-constrained settings.

    Intrahospital variations in antimicrobial profiles may be related to many factors. This study compared causative agents of nosocomial bloodstream infections between a neonatal intensive care unit (NICU) that adopted a ward-tailored antibiotic policy and adult intensive care units (ICUs). Data on organisms from blood cultures obtained from the respective wards between 2005 and 2009 were analyzed. Compared with the adult ICUs, the NICU had a higher frequency of Enterobacteriacae and lower frequencies of typical hospital-acquired pathogens (eg, Klebsiella pneumoniae, 17.4% vs 10.0% [P < .001]; Acinetobacter baumannii, 3.9% vs 11.6% [P < .001]). Antibiotic resistance of gram-negative organisms was also significantly lower in the NICU, including resistance to imipenem (5.7% vs 32.1%; P < .001), amikacin (8.8% vs 30.3%), and ceftriaxone (36.1% vs 74.6%; P < .001). This could possibly be due to the ward-tailored antibiotic policy adopted by the NICU but not by the other ICUs.

    The In vitro susceptibility of clinical and environmental isolates of Acinetobacter baumannii to tigecycline and other antibiotics was determined by disk diffusion method. The E-test was used to determine the minimum inhibitory concentration (MIC). The growth curves of tigecycline treated environmental and clinical strains were established. Fifty-seven percent and 75% of the clinical and environmental isolates were MDR strains, respectively. Ninety-five percent of the clinical isolates were susceptible to tigecycline and 5% showed intermediate resistance with MIC ranging between 0.032 and 3 mg/l. Tigecycline susceptible and intermediate resistance among the environmental isolates were 40% and 60%, respectively, with a significantly lower MIC range of 0.5-4 mg/l. The bacterial growth curves demonstrated the higher ability of the environmental strains to tolerate the antibiotic effects than the clinical strains. The relatively high resistance profile among the environmental isolate suggests an insidious emergence of tigecycline resistance amongst A. baumannii. Strict infection control procedures are imperative to prevent the dissemination of tigecycline-resistant A. baumannii strains in the hospital environment.
