1.Medical Ethics: What You Should Know?
International Journal of Public Health Research 2012;2(1):129-136
Medical ethics is a system of moral principles that apply values and judgments to the practice of medicine. As a scholarly discipline, medical ethics encompasses its practical application in clinical settings as well as work on its history, philosophy, theology, and sociology. The medical profession has long subscribed to a body of ethical statements developed primarily for the benefit of the patient. A physician must recognize responsibility to patients first and foremost, as well as to society, to other health professionals, and to self. This paper presents some information regarding medical ethics, including the values and principles of ethical conduct. Later the requirements of consent form is presented to guide the researchers before conducting a study.

The Medical Journal of Malaysia 2012;67(6):606-609
Introduction: Various studies in primary care and
hospitalized patients have discouraged routine use of chest
x-ray (CXR) in medical examination.
Purpose: The study aims to determine the prevalence of
abnormal routine CXR and cost of one CXR at a public health
clinic and discuss the rationale of CXR in routine medical
examination.
Methodology: Data of patients who visited Klinik Kesihatan
Bandar Kota Bharu (KKBKB), a public health clinic, from 1
January until 31 December 2010 were examined. The study
used cross-sectional design. All patients who came for
medical examination and CXR at KKBKB were included.
Cost analysis was performed from the perspective of
provider.
Findings: About 63.1% of 8315 CXR films in KKBKB were
produced as part of routine medical examination.
Prevalence of abnormal CXR was 0.25%. The cost of
producing one CXR ranges from RM15.87 to RM32.34.
Discussion: Low yield from CXR screening and high cost of
CXR are the main concern. CXR screening would also lead
to unnecessary radiation; and false-positive screening
resulting in physical risk, unwarranted anxiety and more
expenditure. CXR screening is appropriately reserved for
high-risk patients and those with relevant clinical findings.

Background: The idea of launching an internet-based self-management program for patients with diabetes led us to do a cross-sectional study to find out about the willingness, interest, equipment, and level of usage of computer and internet in a medium- to low-social class area and to find the feasibility of using e-telemonitoring systems for these patients. Methods: A total of 180 patients with type 2 diabetes participated in this study and fulfilled the self-administered questionnaire in Diabetes Clinic of Primary Medical Center of University Kebangsaan Malaysia Medical Centre; the response rate was 84%. We used the universal sampling method and assessed three groups of factors including sociodemographic, information and communication technology (ICT), willingness and interest, and disease factors. Results: Our results showed that 56% of the patients with diabetes were interested to use such programs; majority of the patients were Malay, and patients in the age group of 51–60 years formed the largest group. Majority of these patients studied up to secondary level of education. Age, education, income, and money spent for checkup were significantly associated with the interest of patients with diabetes to the internet-based programs. ICT-related factors such as computer ownership, computer knowledge, access to the internet, frequency of using the internet and reasons of internet usage had a positive effect on patients’ interest. Conclusion: Our results show that among low to intermediate social class of Malaysian patients with type 2 diabetes, more than 50% of them can and wanted to use the internet-based self-management programs. Furthermore, we also show that patients equipped with more ICT-related factors had more interest toward these programs. Therefore, we propose making ICT more affordable and integrating it into the health care system at primary care level and then extending it nationwide.

Subclinical hypothyroidism (SHT) is a biochemical diagnosis, defined as an elevated Thyroid Stimulating
Hormone (TSH) with normal free thyroxine (FT4). It affects 4-10% of the adult population and is
more prevalent in elderly women. Its commonest cause is autoimmune thyroiditis, detected by antithyroid
peroxidase antibody (TPO-Ab). About 2-5% of SHT patients progress to overt hypothyroidism
annually. The SHT prevalence among depressed patients ranges between 3% and 17%. This study aimed
to determine the prevalence of SHT and TPO-Ab positivity among patients diagnosed with depressive
disorders. It was a cross-sectional study carried out in the Universiti Kebangsaan Malaysia Medical
Centre over a 12 months period. Serum TSH, FT4 and TPO-Ab were measured. Results showed that
82% of depressed patients were euthyroid, 4% had SHT, 11% had subclinical hyperthyroidism and 2%
had discordant thyroid function. TPO-Ab positivity among the subjects was 7%, one of whom had SHT.
In conclusion, the prevalence of SHT and TPO-Ab positivity in the study population, at 4% and 7%,
respectively, were comparable to previous findings.

The paucity of published literature on periodontal treatment needs and services in developing countries has undermined the significance of periodontal disease burden on healthcare systems. This study analyses periodontal status and population treatment needs of Malaysians, and patterns of periodontal services provided at public sector dental clinics. A retrospective approach to secondary data analysis was employed. Data for population treatment needs were extracted from three decennial national oral health surveys for adults (1990, 2000 and 2010). Annual reports from the dental subsystem of the government Health Information Management System (HIMS) provided information on oral health care delivery for years 2006-2010. They were based on summaries of aggregated data; analyses were limited to reporting absolute numbers and frequency distributions. Periodontal disease prevalence declined between 1990 (92.8%) to 2000 (87.2%) but a sharp rise was observed in the 2010 survey (94.0%). The proportion of participants demonstrating periodontal pockets of 6 mm and more increased in 2010 survey after showing improvements in 2000. Individuals not requiring periodontal treatment (TN0) increased in proportion from 1990 to 2000, only to drop in 2010. An increase in utilisation was observed alongside a growing uptake of periodontal procedures (62.2% in 2006 to 73.6% in 2010). Only about 10% of treatment was surgeries. While the clinical burden of periodontal disease is observed to be substantial, the types of treatment provided did not reflect the increasing needs for complex periodontal treatment. Emphasis on downstream and multi-collaborative efforts of oral health care is deemed fit to contain the burden of periodontal disease.

In Malaysia, dialysis-treated end stage renal disease (ESRD) patients have been increasing rapidly. Haemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) use a disproportionately large amount of limited healthcare resources. This study aims to estimate the costs of HD and CAPD from the Ministry of Health (MOH) perspective. One year prospective multicentre study was conducted from October 2016 to September 2017 to assess direct medical costs of 90 HD patients and 73 CAPD patients from five large MOH dialysis centres. A mixed method of activity-based costing and step-down was used. The capital costs included land, building, medical equipment and furnishing. The recurrent costs included staff emoluments, facility utilities, patients’ medical costs and dialysis consumables. One-way sensitivity analysis was performed to investigate variability in the data. One hundred and forty-one patients (82%) completed the study comprising of 77 patients on HD and 64 patients on CAPD. Majority of the patients were between 46-65 years old (n=75, 53.2%). The most common aetiology of ESRD was diabetes mellitus (44.2% in HD and 48.4% in CAPD). Cost per patient per year was RM39,790 for HD and RM37,576 for CAPD. The main cost drivers were staff emoluments (37.6%) and dialysis consumables (70.5%) for HD and CAPD respectively. HD is highly sensitive towards all the variables analysed except for dialysis consumables. In CAPD, there are minimal sensitivities except for the 5% discount rate. Knowledge of the costs of modalities are useful in the context of planning for dialysis services and to optimise the number of kidney failure patients treated by dialysis within the MOH.

Healthcare workers typically work in shift to ensure smooth operation of healthcare industries around the clock. However, working in shift put them at risk of developing occupational fatigue and sleepiness during and after work, with multiple adverse effects to themselves and patients under their care. This review aims to identify available evidence-based intervention for fatigue and sleepiness among healthcare workers working in shift. We searched PubMed, Scopus and CENTRAL database from January 2013 to December 2017. Selection criteria included randomised controlled trials (RCTs) that investigated the effect of any interventions on fatigue and/or sleepiness among shift workers. Two authors independently screened titles and abstracts for relevant studies, extracted data, and assessed risk of bias. We included 8 relevant trials with 7 review-relevant participants. Given the methodological diversity of the included studies in terms of interventions and assessment tools, it is not possible to determine the effectiveness of these interventions to reduce occupational fatigue or sleepiness among healthcare workers working in shift. More good quality RCTs with comparable assessment tools is needed.

Background: The availability of obesity specific quality of life measurement tool is limited. The Malay version of Impact of Weight on Quality of Life-Lite is an obesity specific quality of life questionnaire which has been translated for use in Malaysia. The aim of this study is to evaluate the validity and reliability of this tool to measure quality of life among different body mass index (BMI) groups.Methods: One hundred and twenty subjects with different BMI categories attending an outpatient government clinic participated in this study. The translated Malay version of IWQOL-Lite was used for assessment. The validity of this questionnaire was examined using content validity, criterion validity and construct validity. Reliability analyses used in this study were internal consistencies and test-retest reliability. Results: The Malay version of IWQOL-Lite showed good psychometric properties whereby the content validity was sufficient as measured by expert panels. The mean score of all IWQOL-Lite domains were able to discriminate between different BMI groups. Good internal consistency was demonstrated by Cronbach alpha of 0.936. Test-retest reliability ranged from 0.828 to 0.932. The physical function score (IWQOL-Lite) correlated positively with Physical Component Summary of Short Form-36 questionnaire. Exploratory factor analysis found that the questions loaded on five domains. Conclusion: The results suggest that the Malay version of IWQOL-Lite is a valid and reliable tool to measure quality of life among obese and overweight subjects in Malaysia.

Introduction: The transboundary smoke haze has become a major concern as it had a wide ranging impact in Southeast Asia from the aspect of public health to national economics. This review aims to synthesize available literature in epidemiology, economics and haze related studies to provide essential information for the valuation of health costs associated with haze in Malaysia. Methods: Evidence on health economic impact of haze was gathered by conducting a literature review and collecting information on the health effects of haze and the cost of it as well as the hospitalization cost from medical illnesses and hospital admissions due to haze. Articles were taken from those that were published from 1999 to 2016.Results: The 1997 Asian Haze episode has caused increasing trend of prematurity of mortality and respiratory problems and several series of haze later had caused increased number of hospitalization. The cost impact on hospital admission ranges from MYR1.8 million in 2005 to MYR118.9 million in 2013. During the 1997 haze, the incremental cost of illness (COI) was noted to be MYR 21million and it shot up to MYR 410 million during the 2013 haze. Conclusion: The haze gives a serious health effect to our country and our neighbours. These health effect has caused a significant health economy impact which include rise in hospital admission cost and medication, incremental cost of illness and extend to cost of medical-related leaves taken and lead to loss of income opportunities.

Introduction: An economic analysis was performed to
estimate the annual cost of diabetes mellitus to Malaysia.
Methods: We combined published data and clinical
pathways to estimate cost of follow-up and complications,
then calculated the overall national cost. Costs consisted of
diabetes follow-up and complications costs.
Results: Patient follow-up was estimated at RM459 per year.
Complications cost were RM42,362 per patient per year for
nephropathy, RM4,817 for myocardial infarction, RM5,345 for
stroke, RM3,880 for heart failure, RM5,519 for foot
amputation, RM479 for retinopathy and RM4,812 for cataract
extraction.
Conclusion: Overall, we estimated the total cost of diabetes
as RM2.04 billion per year for year 2011 (both public and
private sector). Of this, RM1.40 billion per year was incurred
by the government. Despite some limitations, we believe our
study provides insight to the actual cost of diabetes to the
country. The high cost to the nation highlights the
importance of primary and secondary prevention.
