Evaluation of psychometric properties of the malay version perceived stress scale in two occupational settings in malaysia.

BACKGROUND: The 10-item version of Perceived Stress Scale (PSS-10) is a widely used tool to measure stress. The Malay version of the PSS-10 has been validated among Malaysian Medical Students. However, studies have not been conducted to assess its validity in occupational settings. AIM: The aim of this study is to assess the psychometric properties of the Malay version of the PSS-10 in two occupational setting in Malaysia. SUBJECTS AND METHODS: This study was conducted among 191 medical residents and 513 railway workers. An exploratory factor analysis was performed using the principal component method with varimax rotation. Correlation analyses, Kaiser-Meyer-Olkin, Bartlett's test of Sphericity and Cronbach's alpha were obtained. Statistical analysis was carried out using statistical package for the social sciences version 16 (SPSS, Chicago, IL, USA) software. RESULTS: Analysis yielded two factor structure of the Malay version of PSS-10 in both occupational groups. The two factors accounted for 59.2% and 64.8% of the variance in the medical residents and the railway workers respectively. Factor loadings were greater than 0.59 in both occupational groups. Cronbach's alpha co-efficient was 0.70 for medical residents and 0.71 for railway workers. CONCLUSION: The Malay version of PSS-10 had adequate psychometric properties and can be used to measure stress among occupational settings in Malaysia.

Cost Analysis Of Hypertension Management In An Urban Primary Medical Centre Kuala Lumpur

Hypertension is one of the commonest health problems in Malaysia and its cases are on a rise. In conjunction with the above statement, it is predictable that the cost of healthcare services will further increase in the future. Therefore, cost study is necessary to estimate the health related economic burden of hypertension in Malaysia. A cross sectional study was carried out to quantify the direct treatment cost of hypertension. Three hundred and ninety one hypertensive patients’ data from Bandar Tasik Selatan Primary Medical Centre in year 2010 were collected and analysed. The direct treatment costs were calculated. The result showed that out of 391 hypertensive patients, 12.5% was diagnosed hypertensive without any co-morbidity, 25.3% with 1 co-morbidity dyslipidemia only; 4.3% with diabetes mellitus type 2 only; 0.5% with chronic kidney disease only and none with ischaemic heart disease. Patients with 2 co-morbidities (dyslipidemia and diabetes mellitus type 2) were 42.2%; with 3 co-morbidities (diabetes mellitus type 2, dyslipidemia and chronic kidney disease) was 4.3%. The mean cost of direct treatment of hypertension per visit/ year was RM289.42 ±196.71 with the breakdown costs for each component were medicines 72.2%, salary 14.6%, laboratory tests 5.0%, administration 4.4% and radiology tests 3.8%. Dyslipidemia is by far the commonest co-morbidity among hypertensive patients. Direct costs of treating hypertension are mostly dependent on present of co-morbidity and numbers of drugs used. Thus, the annual budget could be calculated precisely in the future especially for drugs.

Prospective Study of Functional Recovery of Stroke Patients at Three Months Post Admission: Outcomes and Implications for Post Stroke Care Provision

Functional recovery in the immediate post stroke period predicts the long-term prognosis of post stroke patients. Despite the advancement in stroke rehabilitation in improving the physical function of survivors, there are other factors that may influence functional recovery. We aimed to assess the functional recovery of ischaemic stroke patients attending a tertiary hospital and its associated factors in order to make recommendations for post stroke care after hospital admission. A three months prospective observational study looking at functional recovery using the Modified Barthel’s Index (MBI) and depression (Patient Heath Questionnaire-9)score of post stroke patients. There were 46 ischaemic stroke patients who were recruited for the study. At three months, only 37 patients were eligible for analysis. The mean age was 67.2 (SD 11) years with the Malays (50%) making up the majority of the patients, followed by Chinese (41.3%) and Indians (8.7%). There was a total of seven (15.2%) deaths. Hypertension was the most common risk factor (89.1%) followed by dyslipidaemia (65.2%) and diabetes mellitus(63.0%). The mean MBI difference was 45.2 (SD 27.0) with a median MBI of 17.0(IQR 33.0) at baseline compared to 85.0(IQR 42.0) at three months (p < 0.001, CI 35.98,55.45). The prevalence of depression (PHQ-9≥10) was 21.6%. Lower functional recovery was found among depressed patients (p <0.026) and among patients with recurrent stroke (p< 0.035). Significant functional recovery can be seen as early as threemonths post stroke. Factors such as recurrent stroke and depression may affect functional recovery post stroke; hence should be routinely screened.

Cost analysis of cataract surgery with intraocular lens implantation: a single blind randomised clinical trial comparing extracapsular cataract extraction and phacoemulsification

A randomised single blinded clinical trial to compare the cost of cataract surgery between extracapsular cataract extraction (ECCE) and phacoemulsification (PEA) was conducted at Hospital Universiti Kebangsaan Malaysia (HUKM) between March and December 2000. A total of 60 patients were included in this study. The cost of a cataract surgery incurred by hospital, patients and households up to two months after discharge were included. The costs of training, loss of patients' income after discharge and intangible costs were excluded. Results showed that the average cost for one ECCE operation is RM1,664.46 (RM1,233.04-RM2,377.64) and for PEA is RM1,978.00 (RM1,557.87-RM3,334.50). During this short period of follow up, it can be concluded that ECCE is significantly cheaper than PEA by an average difference of RM 313.54 per patient (p < 0.001). Cost of equipment and low frequency of PEA technique done in HUKM were the two main reasons for the high unit cost of PEA as compared to ECCE.
