Fulltext Comparative demographics, ROM, and function after TKA in Chinese, Malays, and Indians

Siow WM, Chin PL, Chia SL, Lo NN, Yeo SJ

Clin Orthop Relat Res, 2013 May;471(5):1451-7.
PMID: 23299954 DOI: 10.1007/s11999-012-2776-7

There is marked racial disparity in TKA use rates, demographics, and outcomes between white and Afro-Caribbean Americans. Comparative studies of ethnicity in patients undergoing TKAs have been mostly in American populations with an underrepresentation of Asian groups. It is unclear whether these disparities exist in Chinese, Malays, and Indians.

Impact of ethnic disparities on the treatment outcomes of HIV-negative drug-resistant tuberculosis patients in Kuala Lumpur, Malaysia: A call for a culturally-sensitive community intervention approach

Shariff NM, Shah SA, Kamaludin F

J Glob Antimicrob Resist, 2019 12;19:274-279.
PMID: 31100500 DOI: 10.1016/j.jgar.2019.05.009

OBJECTIVE: Little is known about the treatment outcomes of HIV-negative drug-resistant tuberculosis (TB) patients in Malaysia. With respect to this issue, this study aimed to determine factors associated with unsuccessful treatment outcomes among drug-resistant TB patients at the Institute of Respiratory Medicine, Kuala Lumpur, Malaysia.
METHODS: This retrospective cohort study involved laboratory-confirmed drug-resistant TB patients from January 2009 to June 2013. Multiple logistic regression was used to model the outcome, which was subsequently defined according to the recent definition by the WHO. Data were analysed using IBM SPSS Statistics for Windows version 22.0.
RESULTS: Among the 403 patients who were analysed, 66.7% of them were found to have achieved successful outcomes (cured or completed treatment) while the remaining 33.3% had unsuccessful treatment outcomes (defaulted, treatment failure or died). Multivariable analysis showed that the type of resistance [polyresistant (aOR = 3.00, 95% CI 1.14-7.91), multidrug resistant (MDR) (aOR = 5.37, 95% CI 2.65-10.88)], ethnicity [Malay (aOR = 2.86, 95% CI 1.44-5.71), Indian (aOR = 3.04, 95% CI 1.20-7.70)], and treatment non-compliance (aOR = 26.93, 95% CI 14.47-50.10) were the independent risk factors for unsuccessful treatment outcomes among this group of patients. Notably, the odds of unsuccessful treatment outcome was also amplified among Malay MDR-TB patients in this study (aOR = 13.44, 95% CI 1.99-90.58).
CONCLUSION: In order to achieve better treatment outcomes for TB, effective behavioural intervention and thorough investigation on ethnic disparities in TB treatment are needed to promote good compliance.

Fulltext Barriers to early presentation of self-discovered breast cancer in Singapore and Malaysia: a qualitative multicentre study

Lim JN, Potrata B, Simonella L, Ng CW, Aw TC, Dahlui M, et al.

BMJ Open, 2015 Dec 21;5(12):e009863.
PMID: 26692558 DOI: 10.1136/bmjopen-2015-009863

OBJECTIVE: To explore and compare barriers to early presentation of self-discovered breast cancer in Singapore and Malaysia.
DESIGN: A qualitative interview study with thematic analysis of transcripts.
PARTICIPANTS: 67 patients with self-discovered breast symptoms were included in the analysis. Of these, 36% were of Malay ethnicity, 39% were Chinese and 25% Indian, with an average age of 58 years (range 24-82 years). The number of women diagnosed at early stages of cancer almost equalled those at advanced stages. Approximately three-quarters presented with a painless lump, one-quarter experienced a painful lump and 10% had atypical symptoms.
SETTING: University hospital setting in Singapore and Malaysia.
RESULTS: Patients revealed barriers to early presentation not previously reported: the poor quality of online website information about breast symptoms, financial issues and the negative influence of relatives in both countries, while perceived poor quality of care and services in state-run hospitals and misdiagnosis by healthcare professionals were reported in Malaysia. The pattern of presentation by ethnicity remained unchanged where more Malay delayed help-seeking and had more advanced cancer compared to Chinese and Indian patients.
CONCLUSIONS: There are few differences in the pattern of presentation and in the reported barriers to seek medical care after symptom discovery between Singapore and Malaysia despite their differing economic status. Strategies to reduce delayed presentation are: a need to improve knowledge of disease, symptoms and causes, quality of care and services, and quality of online information; and addressing fear of diagnosis, treatment and hospitalisation, with more effort focused on the Malay ethnic group. Training is needed to avoid missed diagnoses and other factors contributing to delay among health professionals.

Fulltext A qualitative study on healthcare professionals' perceived barriers to insulin initiation in a multi-ethnic population

Lee YK, Lee PY, Ng CJ

BMC Fam Pract, 2012;13:28.
PMID: 22469132 DOI: 10.1186/1471-2296-13-28

BACKGROUND: Nationwide surveys have shown that the prevalence of diabetes rates in Malaysia have almost doubled in the past ten years; yet diabetes control remains poor and insulin therapy is underutilized. This study aimed to explore healthcare professionals' views on barriers to starting insulin therapy in people with type 2 diabetes.
METHODS: Healthcare professionals consisting of general practitioners (n = 11), family medicine specialists (n = 10), medical officers (n = 8), government policy makers (n = 4), diabetes educators (n = 3) and endocrinologists (n = 2) were interviewed. A semi-structured topic guide was used to guide the interviews by trained facilitators. The interviews were transcribed verbatim and analysed using a thematic analysis approach.
RESULTS: Insulin initiation was found to be affected by patient, healthcare professional and system factors. Patients' barriers include culture-specific barriers such as the religious purity of insulin, preferred use of complementary medication and perceived lethality of insulin therapy. Healthcare professionals' barriers include negative attitudes towards insulin therapy and the 'legacy effect' of old insulin guidelines; whilst system barriers highlight the lack of resources, language and communication challenges.
CONCLUSIONS: Tackling the issue of insulin initiation should not only happen during clinical consultations. It requires health education to emphasise the progressive nature of diabetes and the eventuality of insulin therapy at early stage of the illness. Healthcare professionals should be trained how to initiate insulin and communicate effectively with patients from various cultural and religious backgrounds.
Study site: healthcare professionals who provided diabetes care in the three healthcare settings in Malaysia: the government health clinics (Klinik Kesihatan); government university-based primary care clinic and hospital; and private general practice (GP) clinics and hospitals

Fulltext Ethnic disparities in metabolic syndrome in Malaysia: an analysis by risk factors

Tan AKG, Dunn RA, Yen ST

Metab Syndr Relat Disord, 2011 Dec;9(6):441-51.
PMID: 21815810 DOI: 10.1089/met.2011.0031

BACKGROUND: This study investigates ethnic disparities in metabolic syndrome in Malaysia.
METHODS: Data were obtained from the Malaysia Non-Communicable Disease Surveillance-1 (2005/2006). Logistic regressions of metabolic syndrome health risks on sociodemographic and health-lifestyle factors were conducted using a multiracial (Malay, Chinese, and Indian and other ethnic groups) sample of 2,366 individuals.
RESULTS: Among both males and females, the prevalence of metabolic syndrome amongst Indians was larger compared to both Malays and Chinese because Indians are more likely to exhibit central obesity, elevated fasting blood glucose, and low high-density lipoprotein cholesterol. We also found that Indians tend to engage in less physical activity and consume fewer fruits and vegetables than Malays and Chinese. Although education and family history of chronic disease are associated with metabolic syndrome status, differences in socioeconomic attributes do not explain ethnic disparities in metabolic syndrome incidence. The difference in metabolic syndrome prevalence between Chinese and Malays was not statistically significant. Whereas both groups exhibited similar obesity rates, ethnic Chinese were less likely to suffer from high fasting blood glucose.
CONCLUSIONS: Metabolic syndrome disproportionately affects Indians in Malaysia. Additionally, fasting blood glucose rates differ dramatically amongst ethnic groups. Attempts to decrease health disparities among ethnic groups in Malaysia will require greater attention to improving the metabolic health of Malays, especially Indians, by encouraging healthful lifestyle changes.
Study name: Malaysia Non-Communicable Disease Surveillance-1 (MyNCDS-1) survey
