Health system transformation is a complex journey that often results in unintended consequences. Existing methods to drive health system transformation have intrinsic limitations which impede successful implementation in local contexts. The Health System Transformation Playbook is a design-, systems-, and complexity-thinking enabled methodology to systematically design, prioritize and test health system and services transformation actions, anchored on iterative story telling, model building and pathfinding processes that tackles the scale of socially and technologically complex adaptive systems through time.

The personal recovery movement is beginning to gain traction within Singapore's mental healthcare systems. We believe it is timely to give a broad overview of how it developed and provide suggestions on how it can evolve further. From the early custodial care in the 1800s to the community-centric programmes of the 1900s and early 2000s, we now find ourselves at the forefront of yet another paradigm shift towards a more consumer-centric model of care.

The current study seeks to determine how peer support roles change as peer support specialists' positions within organizations and departments mature. We followed ten peer support specialists over the course of a year, interviewing them at three points, starting approximately three months after they began working as peer support specialists. We used an inductive process to analyze our data and followed guidelines on the structuring of longitudinal qualitative trajectories to divide the data into watershed moments.

Stigma towards people with mental illness is widely prevalent in Singapore despite nearly 2 decades of anti-stigma efforts. The latest and most ambitious initiative to tackle stigma, "Beyond the Label", was launched in 2018. We believe that it is timely to highlight the missing gap in Singapore's anti-stigma efforts-the lack of evaluative research on anti-stigma programmes.

People with mental illness may be unable to provide critical input about the care they wish to receive during a psychiatric crisis because of altered mental states. It is therefore imperative that clinicians seek to understand service users' wishes for care while they are well and able to provide meaningful input into the discussion. Achieving such an end may be done by discussing and completing a psychiatric advance directive.

Understanding the lower level of happiness among older adults with cognitive impairment has been a largely neglected issue. This study (1) reports on the level of happiness among older adults in Singapore and (2) examines the potential mediating roles of depression, disability, social contact frequency, and loneliness in the relationship between cognitive scores and happiness. Data for this study were extracted from the Well-being of the Singapore Elderly (WiSE) study: a cross-sectional; comprehensive single-phase survey conducted among Singapore citizens and permanent residents that were aged 60 years and above ( = 2565).

Purpose: To establish the 12-month treatment gap and its associated factors among adults with mental disorders in the Singapore resident population using data from the second Singapore Mental Health Study and to examine the changes since the last mental health survey conducted in 2010.

Methods: 6126 respondents were administered selected modules of the Composite International Diagnostic Interview, to assess major depressive disorder (MDD), dysthymia, bipolar disorder, generalized anxiety disorder (GAD), obsessive compulsive disorder (OCD) and alcohol use disorder (AUD) (which included alcohol abuse and dependence). Past year treatment gap was defined as the absolute difference between the prevalence of a particular mental disorder in the past 12 months preceding the interview and those who had received treatment for that disorder.

Article Synopsis
  • The study investigates the stigma associated with major depressive disorder (MDD) in patients from five Asian countries (China, Korea, Malaysia, Singapore, and Thailand) involving 547 outpatients.
  • It finds that younger patients (under 55) experience significantly higher stigma levels than older patients, with stigma negatively impacting mental health and correlated with various depression and social support factors.
  • Key predictors of perceived stigma include age, symptoms of interpersonal sensitivity and psychoticism, and poor health-related quality of life, identifying young MDD patients with low social support as a key group for targeted stigma reduction efforts.

Objective: Tools generally used in measuring patient safety incidents in general healthcare settings are not considered suitable for mental health settings. The aim of this study was to develop and evaluate a specialized trigger tool for mental health settings that could detect both traditionally defined adverse events (AEs) and other mental health-related patient safety incidents (MHPSIs).

Methods: We first defined and categorized AEs and MHPSIs based on existing literature and then developed a trigger list, initially consisting of 50 items, which was subsequently reduced to 25 items after a pilot study.

Healthcare decision-makers are constantly challenged by growing healthcare needs in tandem with rising healthcare costs. Disinvesting in technologies and practices that are "low in value" is one strategy to re-allocate limited resources to the most effective, safe and cost-effective technologies. We put forward a health technology reassessment framework and examined the opportunities and challenges on technology disinvestment in Singapore and deliberated on possible solutions.

Introduction: The objectives of this current study were to: 1) examine the prevalence and correlates of diabetes mellitus (DM) among older adults (aged 60 years and above) in a multi-ethnic population; 2) examine the prevalence and correlates of comorbid DM and depression among them; and 3) assess the effect of comorbid depression on disability, cognition and healthcare utilisation.

Materials And Methods: Data for the current study came from the Well-being of the Singapore Elderly (WiSE) study; a single phase, cross-sectional survey conducted among Singapore residents aged 60 years and above. A total of 2565 respondents completed the survey; depression was assessed using the Automated Geriatric Examination for Computer Assisted Taxonomy (AGECAT) while a diagnosis of DM was considered if respondents stated that a doctor had diagnosed them with DM.

Objective: This present study estimated the psychiatric morbidity among informal caregivers of older adults and investigated its association with their socio-demographic factors and older adult's health status, including dementia, depression and physical health conditions.

Methods: Data from a national cross-sectional survey were used. For each participating older adult, an informal caregiver who 'knew the older adult best' and was aware of their health condition, was also interviewed to collect information on the older adults' care needs, and behavioral and psychological symptoms of dementia (BPSD).
