Understanding cannabis use in Singapore: profile of users and drug progression.

Introduction: Cannabis has consistently been the third most commonly abused drug among drug arrestees in Singapore over the past few years. Accordingly, this study aimed to understand the profile of cannabis users in Singapore and explore the effects of cannabis use on drug progression. Methods: A total of 450 participants who had used cannabis at least once in their lifetime were recruited from the National Addictions Management Service, prisons, the Community Rehabilitation Centre and halfway houses from August 2017 to May 2018. A face-to-face questionnaire was administered and descriptive analyses were conducted. Results: The mean participant age was 40.9 ± 14.51 years, and 93.1% of them were male. The participants generally initiated cannabis use during adolescence, at a mean onset age of 16.5 ± 4.46 years. Most (89.6%) were introduced to cannabis by peers. Approximately half of them (46.9%) had used cannabis before other illicit drugs and 42.1% of them had used heroin as the succeeding drug. Conclusion: In Singapore, cannabis use is often initiated during adolescence, largely under peer influence. Cannabis users may progress to other illicit drugs, particularly heroin, later in life.

A new paradigm in management of frequent attenders to emergency departments with severe alcohol use disorder-A pilot study for assertive community treatment in Singapore.

Introduction: A majority of frequent users of emergency medical services in Singapore present with alcohol-related problems. These patients are known to engage poorly with traditional addiction services and frequently attend Emergency Departments (EDs) instead, resulting in high healthcare burden. Assertive Community Treatment (ACT) is an alternative intervention to traditional addiction management. ACT involves community visits with focus on holistic care and harm-reduction. Materials and methods: We conducted a prospective before-and-after cohort study at the major tertiary center for addiction disorders in Singapore. The main objective was to evaluate effectiveness of ACT in reducing alcohol-related attendances at EDs nationwide. Socio-demographics, alcohol-related ED attendances, and the Christo Inventory for Substance-misuse Services (CISS) scores were collected for the patients recruited from April 2018 to March 2019. Descriptive analyses and the Wilcoxon Signed-Rank Test were performed. Results: All 14 patients were male with a mean age of 55 years. There was a significant 45.3% reduction in average alcohol-related ED attendances from 6.8 (range 3-22, median 5.5) in the pre-intervention 6-month period, to 3.7 (range 0-28, median 1.5) in the post-intervention 6-month period (Z = -2.244, p = 0.025). CISS scores showed significant improvement from a pre-intervention median of 13.5 (range 9-16) to a post-intervention median of 6.5 (range 1-10, p = 0.001), corresponding to reduction in alcohol-related problem severity. Conclusion: This pilot study suggests that ACT can be effective in reducing alcohol-related ED attendances and alcohol-related problem severity in patients with AUD who frequently attend ED. A multicenter, prospective study using ACT for such patients across four hospitals in Singapore is currently underway.

End-of-life care preferences of nursing home residents: Results of a cross-sectional study.

BACKGROUND: Palliative care services were not available in nursing homes in Singapore. Project CARE (Care At the end-of-life for Residents in homes for the Elderly) was a pilot programme that aimed to promote advance care planning and improve end-of-life care in nursing homes. AIM: We aimed to examine end-of-life care preferences among nursing home residents, and identify factors associated with preference for medical intervention, cardiopulmonary resuscitation and place of death. DESIGN AND SETTING/PARTICIPANTS: A cross-sectional study using data from advance care planning discussions was conducted from September 2009 to April 2012 across seven nursing homes. The advance care planning discussion was conducted with the resident (with a prognosis of 6 months or 1 year), their families and staff from the nursing home and hospital. RESULTS: A total of 600 residents and their families completed the advance care planning discussion. Majority (93.2%) preferred not to proceed with cardiopulmonary resuscitation, 52.3% opted for limited additional intervention at the nursing home with escalation to the hospital if necessary and 77.0% preferred to die at the nursing home. Residents 85+ years (relative risk ratio: 3.34, 95% confidence interval: 1.13-9.93, p = 0.030) were more likely to prefer medical intervention at the nursing home only. No associations were found with the preference for cardiopulmonary resuscitation. Residents who were single, or who were Christians or Catholics (adjusted odds ratio: 2.09, 95% confidence interval: 1.04-4.19, p = 0.039), were more likely to prefer to die at the nursing home. CONCLUSION: Preferences for medical interventions in nursing homes provide support to extend palliative care services to nursing homes, which may benefit residents who are older, single, or Christians or Catholics.

Integrating palliative care across settings: A retrospective cohort study of a hospice home care programme for cancer patients.

BACKGROUND: Terminally ill patients at the end-of-life do transit between care settings due to their complex care needs. Problems of care fragmentation could result in poor quality of care. AIM: We aimed to evaluate the impact of an integrated hospice home care programme on acute care service usage and on the share of home deaths. SETTINGS/PARTICIPANTS: The retrospective study cohort comprised patients who were diagnosed with cancer, had an expected prognosis of 1 year or less, and were referred to a home hospice. The intervention group comprised deceased patients enrolled in the integrated hospice home care programme between September 2012 and June 2014. The historical comparison group comprised deceased patients who were referred to other home hospices between January 2007 and January 2011. RESULTS: There were 321 cases and 593 comparator subjects. Relative to the comparator group, the share of hospital deaths was significantly lower for programme participants (12.1% versus 42.7%). After adjusting for differences at baseline, the intervention group had statistically significantly lower emergency department visits at 30 days (incidence rate ratio: 0.38; 95% confidence interval: 0.31-0.47), 60 days (incidence rate ratio: 0.61; 95% confidence interval: 0.54-0.69) and 90 days (incidence rate ratio: 0.69; 95% confidence interval: 0.62-0.77) prior to death. Similar results held for the number of hospitalisations at 30 days (incidence rate ratio: 0.48; 95% confidence interval: 0.40-0.58), 60 days (incidence rate ratio: 0.71; 95% confidence interval: 0.62-0.82) and 90 days (incidence rate ratio: 0.77; 95% confidence interval: 0.68-0.88) prior to death. CONCLUSION: Our results demonstrated that by integrating services between acute care and home hospice care, a reduction in acute care service usage could occur.

Economic impact analysis of an end-of-life programme for nursing home residents.

BACKGROUND: Due to limited end-of-life discussions and the absence of palliative care, hospitalisations are frequent at the end of life among nursing home residents in Singapore, resulting in high health-care costs. AIM: Our objective was to evaluate the economic impact of Project Care at the End-of-Life for Residents in homes for the Elderly (CARE) programme on nursing home residents compared to usual end-of-life care. DESIGN AND SETTINGS/PARTICIPANTS: Project CARE was introduced in seven nursing homes to provide advance care planning and palliative care for residents identified to be at risk of dying within 1 year. The cases consisted of nursing home residents enrolled in the Project CARE programme for at least 3 months. A historical group of nursing home residents not in any end-of-life care programme was chosen as the matched controls. Cost differences between the two groups were analysed over the last 3 months and final month of life. RESULTS: The final sample comprised 48 Project CARE cases and 197 controls. Compared to the controls, the cases were older with more comorbidities and higher nursing needs. After risk adjustment, Project CARE cases demonstrated per-resident cost savings of SGD$7129 (confidence interval: SGD$4544-SGD$9714) over the last 3 months of life and SGD$3703 (confidence interval: SGD$1848-SGD$5557) over the last month of life (US$1 = SGD$1.3). CONCLUSION: This study demonstrated substantial savings associated with an end-of-life programme. With a significant proportion of the population in Singapore requiring nursing home care in the near future, these results could assist policymakers and health-care providers in decision-making on allocation of health-care resources.

Does practice size matter? Review of effects on quality of care in primary care.

BACKGROUND: There is a trend towards consolidating smaller primary care practices into larger practices worldwide. However, the effects of practice size on quality of care remain unclear. AIM: This review aims to systematically appraise the effects of practice size on the quality of care in primary care. DESIGN AND SETTING: A systematic review and narrative synthesis of studies examining the relationship between practice size and quality of care in primary care. METHOD: Quantitative studies that focused on primary care practices or practitioners were identified through PubMed, CINAHL, Embase, Cochrane Library, CRD databases, ProQuest dissertations and theses, conference proceedings, and MedNar databases, as well as the reference lists of included studies. Independent variables were team or list size; outcome variables were measures of clinical processes, clinical outcomes, or patient-reported outcomes. A narrative synthesis of the results was conducted. RESULTS: The database search yielded 371 articles, of which 34 underwent quality assessment, and 17 articles (13 cross-sectional studies) were included. Ten studies examined the association of practice size and clinical processes, but only five found associations of larger practices with selected process measures such as higher specialist referral rates, better adherence to guidelines, higher mammography rates, and better monitoring of haemoglobin A1c. There were mixed results for cytology and pneumococcal coverage. Only one of two studies on clinical outcomes found an effect of larger practices on lower random haemoglobin A1 value. Of the three studies on patient-reported outcomes, smaller practices were consistently found to be associated with satisfaction with access, but evidence was inconsistent for other patient-reported outcomes evaluated. CONCLUSION: There is limited evidence to support an association between practice size and quality of care in primary care.

Demographic and lifestyle characteristics associated with non-willingness to participate in health promotion programmes among adults of a lower socioeconomic status in Singapore.

INTRODUCTION/OBJECTIVE: Lower socioeconomic groups have been found to have poorer health outcomes and engage in fewer health promoting behaviours. Understanding the reasons behind adverse lifestyle habits and non-willingness to participate in health promotion programmes among lower socioeconomic groups will enable administrators to modify the programmes and increase participation in this population. This study aimed to determine reasons for non-exercise, smoking and non-willingness to participate, and characteristics associated with non-willingness to participate in health promotion programmes among residents in Singapore. METHOD: A cross-sectional survey was conducted on a purposive sample of residents living in four housing developments of one- and two-room households in Singapore from June to October 2009. The patterns of exercise and smoking, receptiveness towards health promotion programmes and the reasons for non-willingness to participate were elicited. Chi-square tests and logistic regression analysis were performed to identify differences between groups. RESULTS: Seven hundred and seventy-eight responses were analysed. Only 36.1% of respondents were willing to participate in at least one health promotion programme (health screening, talk or workshop). Older respondents aged 45-64 years and more than 65 years were less likely to participate than their younger counterparts (18-44 years). Malays were more likely than Chinese to participate, and respondents who do not exercise were less likely to participate than respondents who exercise (regularly/occasionally). Reasons for non-willingness to participate were 'not interested' and 'no time'. CONCLUSION: Health promotion messages should adapt to the needs and situation of the disadvantaged, to increase participation.
