A prospective study on the use of teledermatology in psychiatric patients with chronic skin diseases.

BACKGROUND: To compare the use of live interactive teledermatology versus conventional face-to-face consultation in long-term, institutionalised psychiatric patients with chronic skin diseases. METHODS: All institutionalised psychiatric patients at the Institute of Mental Health with follow-up appointments at the National Skin Centre were assessed for eligibility and invited to participate. Recruited patients were first seen by a dermatologist via videoconferencing, and then by another dermatologist in person, within 1 week. Clinical outcome measures were then assessed by a third independent dermatologist. The following outcome measures were assessed for each paired patient visit: inter-physician clinical assessment, diagnosis, management plan, adverse events and total patient turnaround time (PTAT) for each consultation. RESULTS: There were a total of 13 patients (mean age, 64.6 years; range 44-80) with 27 patient visits. All were male patients with chronic schizophrenia. The predominant skin condition was chronic eczema and its variants (62%), followed by cutaneous amyloidosis (23%) and psoriasis (15%). The level of complete and partial agreement between the teledermatology and face-to-face consultation was 100% for history-taking and physical examination and 96% for the investigations, diagnosis, management plan and the treatment prescribed. The PTAT for teledermatology was 23 min, compared to 240 min for face-to-face consultations. No adverse events were reported. CONCLUSION: Teledermatology was as effective as face-to-face consultation and reduced the PTAT by 90%, resulting in increased patient convenience, operational efficiency and reduced manpower need. Our study supports the safe and cost-effective use of teledermatology for the follow-up of chronic skin conditions in psychiatric patients.

Prevalence of Dementia in People Aged 60 Years and Above: Results from the WiSE Study.

BACKGROUND: The challenge of an aging population with its expected attendant problem of an increase in the number of people with dementia is a growing concern across the world. OBJECTIVE: The aims of this study were to establish the prevalence and risk factors of dementia in Singapore among the elderly resident population (aged 60 years and above). METHODS: The WiSE study was a comprehensive single phase, cross-sectional, epidemiological survey that adapted the 10/66 protocol to establish the 10/66 and the Diagnostic and Statistical Manual of mental disorders -fourth edition (DSM-IV) diagnosis of dementia. 10/66 and DSM-IV dementia diagnosis as established by the survey questionnaires was validated by comparing against a gold standard of clinical assessment. RESULTS: A total of 2,565 respondents completed the study giving a response rate of 65.6%. The validity of 10/66 dementia was higher (sensitivity = 95.6%, specificity = 81.8%) than that of DSM-IV dementia (sensitivity = 75.6%, specificity = 88.6%) when compared against the clinical gold standard. The study found that the prevalence of 10/66 dementia was 10% in the older adult population while the prevalence of DSM-IV dementia was 4.6%. Older age (75 years and above); no formal education, or completed primary education (versus higher education); homemaker and retired status (versus employed); and a history of stroke were associated with a higher risk of 10/66 dementia. CONCLUSION: The establishment of accurate data on the number of people with dementia is essential in the planning of services and initiatives.

First presentation psychosis among the elderly in Singapore.

INTRODUCTION: In tandem with our ageing population, it is observed there is a growing trend of elderly patients presenting for the first time with psychotic symptoms. Clinical experience suggests differences in the phenomenology of late-onset psychosis in our Asian context compared to studies done in the West. This study aimed to analyse the characteristics and psychopathology of first presentation psychosis in our local elderly and to determine the treatment outcome over a 12-month period. METHODS: A total of 64 subjects with first presentation psychosis were consecutively recruited. Those with a non-affective, non-organic psychotic disorder were evaluated using the Positive and Negative Symptoms Scale, the Clinical Global Impression Scale, Mini-Mental State Examination and the Beck's Depression Inventory. RESULTS: Of the 64 subjects recruited, 55 were enrolled in the study. 59.3% (n = 32) of the subjects were diagnosed to be suffering from very-late-onset schizophrenia-like psychosis, followed by delusional disorder in 31.5% (n = 17). The remaining 11.1% (n = 6) were diagnosed to have late-onset schizophrenia. The sample showed a high preponderance of women, with 88.9% reporting persecutory-type delusions. The majority of them were married and 80% of the subjects were living with relatives. Treatment was effective in ameliorating symptoms, but there was a high loss to follow-up of male subjects (81.8%). CONCLUSION: This descriptive study found sociodemographic and phenomenological similarities to other studies of late-onset psychosis in the West, except that social isolation and partition delusions were not prominent.

Reducing antipsychotic polypharmacy among psychogeriatric and adult patients with chronic schizophrenia.

INTRODUCTION: At the Institute of Mental Health/Woodbridge Hospital, 55% of the long-stay patients are on more than two antipsychotics for treatment of chronic schizophrenia. Our aim was to reduce antipsychotic polypharmacy (APP) among chronic schizophrenia inpatients at the long-term wards at the Institute of Mental Health, Singapore from 2006 to 2008. METHODOLOGY: Using Clinical Practice Improvement Program (CPIP) methodology and using a Plan, Do, Study, Act approach, we surveyed patients, physicians, and nurses for responses regarding reducing the amount of APP for psychiatric patients. The first CPIP (CPIP1) was conducted from August 2006 to January 2007, and focused on psychogeriatric chronic schizophrenia inpatients. This methodology was spread to a second CPIP (CPIP2) from April 2008 to October 2008, which focused on adult chronic schizophrenia inpatients. RESULTS: Both CPIPs were successful in the reduction of APP within the geriatric and adult long-term patients. For CPIP1, eight patients had their antipsychotics reduced. There was a reduction of an average chlorpromazine-equivalent dose per day from 375 mg per patient to 170 mg. For CPIP2, the average number of antipsychotics was reduced from 2.9 to 2.27 from July 2008 to October 2008. There was a reduction of an average chlorpromazine-equivalent dose per day from 1523 mg per patient to 1246 mg. There was no documented relapse within six months of implementation of both the projects. CONCLUSION: APP in long-term patients suffering from chronic schizophrenia can be safely reduced with proper clinical titration, aided by guidelines and protocols.
