Screening for cardiovascular disease risk factors at baseline and post intervention among adults with intellectual disabilities in an urbanised Asian society.

BACKGROUND: Adults with intellectual disabilities (ID) face significant barriers to screening participation. We determined predictors for regular cardiovascular health screening at baseline among adults with ID in Singapore, and evaluated the effectiveness of a 3-month screening intervention. METHODS: The study population involved all adults with ID aged ≥40 years receiving services from the Movement for the Intellectually Disabled of Singapore (MINDS), the largest such provider in Singapore. Over 3 months in 2011, adult clients not screened regularly at baseline for hypertension, diabetes and dyslipidaemia were offered free and convenient blood pressure, fasting blood glucose and lipid testing; data on other cardiovascular disease risk factors were also collected. Chi-square and logistic regression identified predictors of regular screening at baseline. RESULTS: Participation was 95.0% (227/239). At baseline, among adults with ID, 61.8% (118/191), 24.8% (52/210) and 18.2% (34/187) had gone for regular hypertension, diabetes and dyslipidaemia screening respectively; post intervention, rates rose to 96.9%, 89.5% and 88.8% respectively. Prevalence of cardiovascular disease risk factors (22.5% with hypertension, 10.6% with diabetes, 34.8% with dyslipidaemia, 10.7% obese and 90.6% lacking regular exercise) was high compared against the general population. While receiving residential services was associated with regular hypertension screening, receiving non-residential services and being independently mobile were associated with regular participation in fasting blood tests (all P < 0.05). CONCLUSION: Cardiovascular disease risk factors are common among adults with ID and clinicians should proactively screen such populations. Provision of free and convenient screening for cardiovascular disease risk improved screening participation.

Community psychiatry in Singapore: a pilot assertive community treatment (ACT) programme.

Severe mental illnesses cause their sufferers dismal functional impairment. The Global Burden of Disease lists schizophrenia among the top 10 contributors to health burden and disability around the world. In the Institute of Mental Health (IMH) of Singapore, 9 out of 10 Class-C beds are occupied by patients whose hospitalisation periods last 300 days on average. Whilst de-institutionalisation has not seen its expected level of success overseas, the provision of community-based psychiatric care has been shown to be more cost-effective than hospital-based inpatient care. As such, there is a need for increased emphasis on community psychiatric services, both to provide and to effectively utilise available resources to assist patients with severe mental illnesses in living and functioning within the community. In line with several other efforts, a pilot Assertive Community Treatment or ACT Programme was launched by IMH in November 2003. This article details the aims, set-up and services of this pilot project funded by the Health Service Development Programme (HSDP) for 3 years, which receives referrals from IMH psychiatrists. With the services provided by the ACT team including psychosocial rehabilitation, it is hoped that patients will continue to receive adequate psychiatric care as well as maintain sufficient skills for self-care and independent living within the community despite the well-documented deteriorating course of psychotic illnesses like schizophrenia.

The effects of blood on rapid urease testing for Helicobacter pylori in mucosal biopsies from the gastric antrum.

BACKGROUND: While the eradication of Helicobacter pylori in patients with bleeding peptic ulcer disease (PUD) decreases the rate of ulcer re-bleeding, the sensitivity of the rapid urease test (RUT) for H. pylori diagnosis is lower in this setting. The aim of this study was therefore to determine if exposing a gastric biopsy specimen to blood before its use in the RUT (CLOtest) could account for these findings. METHODS: In patients undergoing endoscopy for the evaluation of dyspepsia gastric mucosal biopsies were obtained for H. pylori diagnosis (RUT, microbiology, and histology). Mucosal biopsies from each patient were also exposed to blood for 15, 30 and 45 minutes before use in the RUT. RESULTS: Using a combination of diagnostic tests (histology, microbiology and routine CLOtest) as the 'gold standard', the sensitivity, specificity, positive predictive value and negative predictive value of the CLOtest remained above 90% despite prior exposure of the gastric biopsy specimen to blood, and these values were not significantly different from the performance characteristics of the CLOtest processed in a routine manner. CONCLUSION: The exposure of gastric mucosal biopsy specimens to blood alone is not the explanation for the reduced sensitivity of the RUT in patients with bleeding peptic ulcers.
