What are the direct medical costs of managing Type 2 Diabetes Mellitus in Malaysia?

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.

Most prevalent unmet supportive care needs and quality of life of breast cancer patients in a tertiary hospital in Malaysia.

BACKGROUND: Addressing breast cancer patients' unmet supportive care needs in the early stage of their survivorship have become a prime concern because of its significant association with poor quality of life (QOL), which in turn increases healthcare utilization and costs. There is no study about unmet supportive care needs of breast cancer patients in Malaysia. This study aims to assess the most prevalent unmet supportive care needs of Malaysian breast cancer patients and the association between QOL and patients' characteristics, and their unmet supportive care needs. METHODS: A cross-sectional study was conducted at the Surgery and Oncology Clinic between May 2014 and June 2014 in a tertiary hospital in Malaysia. A total of 117 patients out of 133 breast cancer patients recruited by universal sampling were interviewed using a structured questionnaire consisted of three parts: participants' socio-demographic and disease characteristics, Supportive Care Needs Survey-Short Form Questionnaire (SCNS-SF34) and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30). RESULTS: The highest unmet supportive care needs were observed in the psychological domain (Mean 53.31; SD ± 21.79), followed by physical domain (Mean 38.16; SD ± 27.15). Most prevalent unmet supportive care needs were uncertainty about the future (78.6 %), fears about the cancer spreading (76.1 %), feelings of sadness (69.2 %), feelings about death and dying (68.4 %), concerns about those close to the patient (65.0 %) and feeling down or depressed (65.0 %). Multivariate linear analysis showed that early breast cancer survivors diagnosed at an advanced stage and with greater physical and psychological needs were significantly (p < 0.05) associated with poorer QOL. CONCLUSION: Most prevalent unmet needs among Malaysian breast cancer patients were found in the psychological domain. Early breast cancer survivors with late stage diagnosis who had more unmet needs in psychological and physical domains were more likely to have a poor QOL.

Urinary tract infection and bacteriuria in children performing clean intermittent catheterization with reused catheters.

STUDY DESIGN: This study was designed as a comparative cross-sectional cross-over trial on children performing clean intermittent catheterization (CIC) with reused catheters for 1 or 3 weeks. OBJECTIVES: To determine the incidence of symptomatic urinary tract infection (UTI) and bacteriuria (defined as colony count of ⩾105 colony forming units per ml of a single strain of organism) in these two different frequencies of catheter change. SETTING: Multidisciplinary children's neurogenic bladder clinics at two tertiary care hospitals in Kuala Lumpur Malaysia. METHODS: Forty children aged between 2 and 16 years performing CIC for at last 3 years were recruited. Medical and social data were obtained from case files. Baseline urine cultures were taken. All children changed CIC catheters once in 3 week for the first 9 weeks followed by once a week for the next 9 weeks. Three-weekly urine cultures were obtained throughout the study. Standardization of specimen collection, retrieval and culture was ensured between the two centers. RESULTS: At baseline, 65% of children had bacteriuria. This prevalence rose to 74% during the 3-weekly catheter change and dropped to 34% during the weekly catheter change (Z-score 6.218; P<0.001). Persistence of bacteriuria (all three specimens in each 9-week period) changed significantly from 60 to 12.5%, respectively (P<0.005). There was no episode of UTI during the 18-week study period. CONCLUSION: Reuse of CIC catheters for up to 3 weeks in children with neurogenic bladders appears to increase the prevalence of bacteriuria but does not increase the incidence of symptomatic UTI.

Urinary bladder characteristics via ultrasound as predictors of acute urinary retention in men with benign prostatic hyperplasia.

OBJECTIVE: To determine the clinical utility of urinary bladder and prostate characteristics measured by ultrasound scan in predicting acute urinary retention (AUR) for men with bladder outlet obstruction with an underlying benign prostate hyperplasia (BPH). MATERIALS AND METHODS: Consecutive men aged ≥50 years presenting with lower urinary tract symptoms (LUTS) or AUR were prospectively recruited in this cross-sectional study. International prostatic symptom score (IPSS) and serum prostate-specific antigen (PSA) were recorded. High-resolution ultrasound was used to measure bladder detrusor thickness (DT, mm), prostatic volume (PV, cm3), intravesical prostatic protrusion (IPP, mm), bladder wall thickness (BWT,mm), intravesical volume and bladder radius. The latter two parameters were used to estimate bladder weight (UEBW, g), assuming a spherical bladder. RESULTS: Among selected patients, thirty had AUR while 32 men presented with LUTS only. There were significant differences between those with and without AUR in their age (70.5 vs 66.0, p=0.017), IPSS (24.0 vs 18.5, p=0.009), serum PSA (6.18 vs 1.77, p=0.002), PV (56.7 vs 32.4, p=0.006), BWT (5.0 vs 4.4, p=0.034) and UEBW (39.1 vs 25.0, p=0.0003). Multivariate analysis revealed high IPSS and UEBW to be predictors for AUR. UEBW was the strongest predictor of AUR: area under ROC curve was 0.767, with sensitivity and specificity of 63.3% and 87.5%, respectively, at cut-off point of 35 g. The likelihood ratio for AUR was also best with UEBW≥35 g. CONCLUSIONS: Combined with IPSS, ultrasound determined bladder characteristic, particularly UEBW, is a useful tool in predicting AUR in men with BPH.

Quality of life in Malaysian colorectal cancer patients: a preliminary result.

OBJECTIVE: Rapidly increasing colorectal cancer (CRC) incidence in Malaysia and the introduction of cutting edge new treatments, which prolong survival, mean that treatment outcome measures meed to be evaluated, including consideration of patient's quality of life (QoL) assessment. There are limited data on QoL in CRC patients, especially in Malaysia. Therefore, this study was performed focusing on cancer stages and age groups. METHODS: The cross sectional study was conducted from June to September 2011 at three public tertiary hospitals with the EORTC QLQ C-30 questionnaire in addition to face to face interview and review of medical records of 100 respondents. RESULTS: The mean age was 57.3 (SD 11.9) years with 56.0% are males and 44.0% females, 62% of Malay ethnicity, 30% Chinese, 7% Indian and 1% Sikh. Majority were educated up to secondary level (42%) and 90% respondents had CRC stages III and IV. Mean global health status (GHS) score was 79.1 (SD 21.4). Mean scores for functional status (physical, emotional, role, cognitive, social) rangeds between 79.5 (SD 26.6) to 92.2 (SD 13.7). Mean symptom scores (fatigue, pain, nausea/vomiting, constipation, diarrhea, insomnia, dyspnoea, loss of appetite) ranged between 4.00 (SD 8.58) to 20.7 (SD 30.6). Respondents role function significantly deteriorates with increasing stage of the disease (p=0.044). Females had worse symptoms of pain (p=0.022), fatigue (p=0.031) and dyspnoea (p=0.031). Mean insomnia (p=0.006) and diarrhea (p=0.024) demonstrated significant differences between age groups. CONCLUSION: QOL in CRC patients in this study was comparable to that in other studies done in developed countries. Pain, fatigue and dyspnoea are worse among female CRC patients. Given that functions deteriorates with advanced stage of the disease at diagnosis, a systematic screening programme to detect cases as early as possible is essential nationwide.

The Effects of Fixed Combination of Bimatoprost-Timolol and Travoprost-Timolol on Intraocular Pressure in Patients With Primary Open-Angle Glaucoma or Ocular Hypertension, Previously on Nonfixed Combination of Latanoprost and Timolol.

PURPOSE: To compare the effects of fixed combination of bimatoprost-timolol and travoprost-timolol on intraocular pressure (IOP) in patients with primary open-angle glaucoma or ocular hypertension. DESIGN: This was a prospective, randomized, observer-masked, crossover parallel comparison trial. METHODS: Forty-one patients with primary open-angle glaucoma or ocular hypertension on nonfixed combination of latanoprost and timolol with IOP of 21 mm Hg or less were randomized to either bimatoprost-timolol or travoprost-timolol fixed combinations for 8-week treatment period. Intraocular pressure was measured at 8 AM, 12 PM, 4 PM, and 8 PM at the baseline and at the end point. Conjunctiva hyperemia and superficial punctate keratopathy after treatment with each fixed combination therapy were assessed and compared with the baseline. Patients were then switched to the opposite drug without a medication-free period for another 8-week, and diurnal IOP measurement was repeated. RESULTS: Bimatoprost-timolol fixed combination reduced the baseline mean diurnal IOP statistically significantly from 17.3 mm Hg [95% confidence interval (CI), 16.8-17.7 mm Hg] to 16.4 mm Hg (95% CI, 15.9-17.0 mm Hg) (P = 0.036). Travoprost-timolol fixed combination lowered the mean diurnal IOP to 17.1 mm Hg (95% CI, 16.5-17.7 mm Hg), but it was not significant. Direct comparison between the 2 fixed combinations showed no significant difference. Both fixed combinations had no significant effect on conjunctiva hyperemia. Interestingly, patients on travoprost-timolol fixed combination had significantly less superficial punctuate keratopathy (P = 0.012). CONCLUSIONS: Both fixed combination of bimatoprost-timolol and travoprost-timolol had no significantly different ocular hypotensive effect. However, bimatoprost-timolol fixed combination produced additional IOP lowering in patients previously treated with nonfixed combination of latanoprost and timolol.

Chest x-ray as an essential part of routine medical examination: is it necessary?

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.

Caregivers' satisfaction of healthcare delivery at paediatric clinics of Universiti Kebangsaan Malaysia Medical Centre in 2009.

Patient's satisfaction has become increasingly important as patients evaluate healthcare services for both medical cost and quality. The purpose of this study was to measure the prevalence and the factors influencing caregivers' satisfaction. A cross sectional study of 262 respondents using universal sampling method was conducted at the paediatric clinics of Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Overall, 90.5% were satisfied with the services provided. Satisfaction rates based on various healthcare delivery domains were: 95.0% for communication skills, 88.5% for interpersonal aspect, 83.6% for technical quality, 82.1% for financial aspect, 72.9% for time spent with doctors and 64.9% for ease of contact. This study shows that the caregivers (an unpaid person who helps a person cope with disease) were highly satisfied with the communicational aspect delivered by the clinic. However, there is still room for improvement on ease of contact domain and waiting time in order to produce high quality service.

Comparing extracorporeal shock wave lithotripsy and ureteroscopy for treatment of proximal ureteric calculi: a cost-effectiveness study.

Extracorporeal shockwave lithotripsy (ESWL) and ureteroscopy (URS) are two main methods of treating proximal ureteric stones. Success rates and cost-effectiveness of the two methods were compared. A total of 67 patients who underwent treatment between January 2007 and July 2007 at a state general hospital were included in the study. The success rate for ESWL group was 81.8% and for URS group was 84.6%. ESWL technique produced a significant higher overall cost per patient than URS (RM930.02 versus RM621.95 respectively). There was no significant difference in quality of patient's life. Cost-effectiveness ratio was lower for URS. The analysis suggested that URS was more cost-effective than ESWL.

Piperacillin-tazobactam plus amikacin as an initial empirical therapy of febrile neutropenia in paediatric cancer patients.

INTRODUCTION: We evaluated piperacillin-tazobactam in association with amikacin in the initial empirical therapy of febrile neutropenic children. METHODS: An open-labelled, non-randomised, prospective trial to assess the efficacy and safety of this association was conducted from June 1, 2001 to December 31, 2002. Children and adolescents were treated for a haematological malignancy or a primary, refractory or relapsed solid tumour, and presented with febrile neutropenia. Patients received intravenous piperacillin-tazobactam (90 mg/kg/dose every eight hours) plus a single daily dose of amikacin at 15 mg/kg/day, maximum 250 mg. If fever persisted, second-line therapy with carbapenem was administered. Teicoplanin was added for gram-positive isolates or for unremitting fever after 48 hours, if clinically indicated. Amphotericin B was added at 96 hours, if fever and neutropenia persisted. RESULTS: 155 episodes of fever and neutropenia in 76 patients were evaluable. 40 (25.8 percent) episodes were a microbiologically-documented infection, 30 (19.4 percent) were clinically-documented, and 85 (54.8 percent) were unexplained fever. 77 (49.7 percent) episodes responded to piperacillin-tazobactam plus amikacin without a need for treatment modification. A higher success rate (63.5 percent) was observed in episodes with unexplained fever. The predominant pathogens isolated in our study were gram-negative organisms (70.7 percent). A mild gastrointestinal intolerance occurred in 35 out of 155 (22.6 percent) episodes. CONCLUSION: This study suggests that piperacillin-tazobactam plus amikacin presents a satisfactory efficacy and a good tolerance as initial empirical therapy for febrile neutropenic children.

The electroencephalogram changes in migraineurs.

Migraine is associated with a variety of electroencephalographic (EEG) changes. Previous studies using analogue EEG and old diagnostic criteria may under or over report the prevalence of EEG changes in migraine. The objective of this study was to reevaluate the EEG changes in migraine patients diagnosed by applying the new International Classification of Headache Disorder -2 criteria. This was a case control study involving 70 migraine patients and 70 age and gender matched control who were subjected to scalp EEG. The EEG changes during hyperventilation (HV), which were significantly more common in the migraine group were theta activity (34 vs 22, p = 0.038) and frontal intermittent rhythmic delta activity (FIRDA) (10 vs 3, p = 0.042). Applying the new ICHD -2 diagnostic criteria and digital EEG, this study yielded previously unrecognized features including FIRDA during HV on EEG.

The coexistence of anxiety and depressive personality traits in migraine.

INTRODUCTION: Migraine is associated with a variety of personality traits. The objective of this study was to reevaluate the personality traits using Minnesota Multiphasic Personality Inventory-2 (MMPI-2) in migraine patients diagnosed by applying the new International Classification of Headache Disorders-2 criteria. METHODS: This was a case control study involving 70 migraine patients and 70 age- and gender-matched controls. The personality traits in the two groups were analysed using the MMPI. Data was analysed using the chi-square test. RESULTS: The migraine patients showed a higher MMPI score on the following personality traits: depression (39 versus 15, p-value is less than 0.0005), and anxiety (24 versus 11, p-value equals 0.011). Both depressive and anxiety personality traits were significantly higher in migraine patients. CONCLUSION: All migraine patients should probably be screened for their personality traits and psychopathology using the MMPI.

Factors associated with control of type I diabetes in Malaysian adolescents and young adults.

OBJECTIVES: To examine the association between ethnicity, depression, quality of life, and diabetic control in Malaysian adolescents and young adults with type I diabetes mellitus. METHODS: Fifty-two outpatients with type I diabetes (mean age 15.5 years) who attended a Diabetes Clinic were included. The level of HbA1c was the measure of diabetes control used (better control defined as HbA1c < 10%). Other variables were measured through questionnaires (e.g., depressive symptoms, quality of life), computerized diagnostic interviews (major depression), and medical records (e.g., demographic, family circumstances, compliance with treatment). RESULTS: Ethnic Chinese youth showed better diabetic control than Malays and Indians (mean HbA1c 9.1%, 10.3%, and 11.0% respectively). Young people with better diabetic control (HbA1c < 10%) were more likely to have better quality of life and less likely to live in problematic families. When the cut-off for diabetic control was stricter (HbA1c < or = 8%), the young person's compliance was the main predictor of poor control. Family problems were also associated with poor control but to a lesser extent. The initial association between poorer diabetes control and depression became non-significant when quality of life was taken into account. CONCLUSIONS: There are ethnic differences in juvenile diabetic control in this Malaysian sample which need to be understood further. Previous findings of an association between quality of life and glycemic control were verified but different definitions of good control showed different associations with individual and environmental variables. Clinicians' awareness and early intervention for psychosocial problems (for example, inadequate family support) could improve diabetes control.

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.
