Orthostatic hypotension: prevalence and associated risk factors among the ambulatory elderly in an Asian population

<p><b>INTRODUCTION</b>The prevalence of orthostatic hypotension (OH) among the elderly population in Singapore, as defined by a decline in blood pressure upon a change in position, is not well-established. Studies associate OH with clinically significant outcomes such as falls. This study aims to determine the prevalence of OH among elderly patients attending a public primary care clinic (polyclinic) for chronic disease management, and examine the relationships between postulated risk factors and OH.</p><p><b>METHODS</b>Patients aged ≥ 65 years attending a typical polyclinic in Geylang were identified and targeted for recruitment at the study site. A questionnaire on symptoms and postulated risk factors was administered, followed by supine and standing blood pressure measurements. Cross-sectional analysis was performed with independent sample t-test for continuous data and chi-square test for categorical data. Prevalence rate ratios with 95% confidence interval were calculated for the latter.</p><p><b>RESULTS</b>A total of 364 multiethnic patients participated in the study. The prevalence of OH was 11.0%. Older age, comorbidities such as cardiac failure and kidney disease, being physically inactive at work, fatigue, self-reported dizziness in the past year, and the use of loop diuretics were found to be significantly associated with OH.</p><p><b>CONCLUSION</b>About one in ten elderly patients at a local polyclinic was affected by OH, which was associated with multiple factors. Some of these factors are modifiable and can be addressed to reduce the incidence of OH.</p>

Academy of Medicine-Ministry of Health clinical practice guidelines: attention deficit hyperactivity disorder

The Academy of Medicine (AMS) and the Ministry of Health (MOH) have developed the clinical practice guidelines on Attention Deficit Hyperactivity Disorder (ADHD) to provide doctors and patients in Singapore with evidence-based treatment for ADHD. This article reproduces the introduction and executive summary (with recommendations from the guidelines) from the MOH clinical practice guidelines on ADHD, for the information of SMJ readers. Chapters and page numbers mentioned in the reproduced extract refer to the full text of the guidelines, which are available from the Ministry of Health website: http://www.moh.gov.sg/content/moh_web/healthprofessionalsportal/doctors/guidelines/cpg_medical.html.The recommendations should be used with reference to the full text of the guidelines. Following this article are multiple choice questions based on the full text of the guidelines.

Effects of CBT on children with disruptive behaviour disorders: findings from a Singapore study

Objective: The study examines the effectiveness of a CBT treatment programme over and above that of Treatment As Usual (TAU), with children who were referred to an outpatient child psychiatric clinic for disruptive behaviour disorders in Singapore. Methods: One hundred and three children aged 8 to 12 (mean±SD=10.22±1.31) who participated in the study were assigned to either the CBT+TAU (n= 51) or TAU group (n=52). Children in both the CBT+TAU and TAU groups received a standard and typical service offered to children at the outpatient child psychiatric clinic. In addition, children in the CBT+TAU group attended the CBT treatment programme that consisted of nine 1.5 hour weekly sessions. Results: Findings from ANCOVA indicated that children in the CBT+TAU treatment group showed significantly lower levels of aggression and significantly lower levels of parental stress at posttreatment and at 3-month follow-up in comparison to the TAU group. Conclusions: Findings from the present study provided some evidence of the effects of CBT in reducing aggressive behaviour and parental stress among children with disruptive behaviour disorders. Interpretation of the findings, recommendations for future research, and implications of the present study were presented.
