Health Promotion Board-Ministry of Health clinical practice guidelines: functional screening for older adults in the community.

The Health Promotion Board (HPB) and the Ministry of Health (MOH) publish clinical practice guidelines to provide doctors and patients in Singapore with evidence-based guidance on managing important medical conditions. This article reproduces the introduction and executive summary (with recommendations from the guidelines) from the HPB-MOH clinical practice guidelines on Functional Screening for Older Adults in the Community, for the information of readers of the Singapore Medical Journal. Chapters and page numbers mentioned in the reproduced extract refer to the full text of the guidelines, which are available from the Health Promotion Board website (http://www.hpb.gov.sg/uploadedFiles/HPB_Online/Publications/CPGFunctionalscreening.pdf). 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.

Validation and comparison of three brief depression scales in an elderly Chinese population.

The study aimed to establish the diagnostic accuracy of the Geriatric Depression Scale (GDS), the Even Briefer Assessment Scale for Depression (EBAS DEP), and the single question test for depression in our elderly Chinese population, and to determine if any one instrument was to be preferred. Ninety-eight community-living, socially active and non-depressed elderly and 75 patients diagnosed with depression were administered the three depression scales. Receiver operating characteristics (ROC) were employed to determine the optimal cut-off scores for the GDS and EBAS DEP, and the diagnostic performance of all three instruments were then compared. ROC analysis indicated an optimal cut-off score of 4 and above for the 15-item GDS, with a sensitivity of 84.0% and a specificity of 85.7%, while the EBAS DEP had 77.3% sensitivity and 89.8% specificity at the optimal cut-off score of 3 and above. The sensitivity and specificity of the single question were 64.0% and 94.9%, respectively. The non-parametric test of the areas-under-the-curve showed no significant difference between the diagnostic performances of the GDS and the EBAS DEP; visually, however, the ROC plot of the GDS was superior. The GDS, the EBAS DEP, and the single question were all valid screening tools for depression in the elderly Chinese population. For busy physicians, there is rationale to first use the single-question test, supplemented where necessary with either the GDS or the EBAS DEP, as an efficient diagnostic strategy for identifying depression amongst older Chinese patients.

Depression of old age.

Depression is a common and serious psychiatric problem in the elderly causing suffering to the patients and their carers. Its aetiology include biological causes, psychosocial events, physical illnesses and medication. Clinically, the symptoms are similar to those found in younger patients, but certain symptoms eg somatisation and agitation are more common. Depression in the elderly are often misdiagnosed as physical illnesses and dementia and vice versa as they occur commonly in the elderly and share some similar symptoms. In treatment, the elderly patient's altered pharmacokinetics must be taken into consideration. Some side-effects of antidepressants are not only troublesome but also potentially dangerous in the elderly. Electroconvulsive therapy can be life-saving in those who are severely retarded and refuse food. Depression in old age tends to run a chronic course. Relapse rates are high in those who recover.

Mortality of public mental health patients: a Singapore experience.

This study reports the Standardised Mortality Ratio (SMR) by age and sex among public mental health patients in Singapore. The authors also examine the differences between those who were classified as "inpatient deaths" and those who were classified as "outpatient deaths". Mortality was 5.1 times that of the general population and the SMR was most accentuated in the younger, female patients. Of the 217 deaths documented over two years, schizophrenia was the most common diagnosis. Inpatient deaths (N = 120) occurred in older patients with prior physical illness who died of natural causes. In contrast, outpatient deaths (N = 97) involved younger patients with no previous illness and the majority jumped to their deaths. Mortality studies are necessary in monitoring the efficacy of mental health provisions.

Mortality among psychiatric inpatients in Singapore.

This study examines the Standardized Mortality Ratio (SMR) by age, sex and cause of death among psychiatric inpatients in Singapore. Mortality in mentally ill inpatients was found to be 2.79 times that of the general population. The SMR decreased with age and the SMR for those 70 years and above was lower than that reported in the literature. The mortality ratio was most accentuated in the younger patients, especially in the female. Excess mortality was observed in both the natural as well as the unnatural causes of death. Among the natural causes of death, infection and pneumonia showed high excess in mortality. In the unnatural causes of death, suicide was predominant.
