Background: Advance Choice Documents (ACDs) have been recommended for use in England and Wales based on evidence from trials that show that they can reduce involuntary hospitalisation, which disproportionately affects Black African and Caribbean people. Our aim was therefore to develop and test ACD implementation resources and processes for Black people who have previously been involuntarily hospitalised and the people that support them.

Methods: Resource co-production workshops were held to inform the development of the ACD template and two types of training for all stakeholders, comprising a Recovery College course and simulation training.

Objectives: With increasing life expectancy and rapid ageing, there is an expanding number of older people who have functional declines, greater needs for care and support and who are at increased risk of insufficient social interaction. Longitudinal investigations on the interplay between loneliness, social isolation and care dependence remain limited. This study thus aimed to investigate the longitudinal reciprocal association between social isolation/loneliness and care dependence among older adults in Latin America and China.

Introduction: Being on a waiting list for elective (planned) cardiac surgery can be physically and psychologically challenging for patients. Research suggests that stress associated with waiting for surgery is dependent on different individual and contextual factors. However, most data on patients' experiences of waiting for surgery and preferences for waiting list management derives from non-cardiac clinical populations.

Background: Return on Investment (ROI), whereby the ratio of costs to benefits is assessed, is encouraged in-order to justify the value of Quality Improvement (QI) programmes. We previously performed a literature review to develop a ROI conceptual framework for QI programmes. We concluded that, QI-ROI is conceptualised as any monetary and non-monetary benefit.

Background: The aim of this study is to investigate the effects on population level mental health literacy (MHL) of Every Mind Matters over 30 months following campaign launch.

Methods: To observe changes in MHL over time, we conducted regression analyses on a nationally representative, repeated cross-sectional dataset of nine survey waves from September 2019 to March 2022 and an individual participant data meta-analysis with data from October 2019 to March 2021 to examine the association between campaign awareness and the outcomes.

Results: There were small improvements in knowledge of management of stress, depression and anxiety, mental health vigilance, sleep literacy and psychological wellbeing self-efficacy from September 2019 to March 2020 and a deterioration in most MHL outcomes from March 2020 compared with September 2019.

Introduction: Contributing to society constitutes an essential part of healthy ageing. To date, however, it remains unclear how valuable contributions such as caregiving and volunteering, also described as unpaid productive activities, are related to older adults' loneliness. The present longitudinal study addresses this question in a lower-middle-income country, in Indonesia.

This study examined the psychometric properties of the seven-item mastery scale among 392 family caregivers of care dependent older adults in a tertiary hospital in Singapore. Item response theory (IRT) analysis and confirmatory factor analysis (CFA) were used to assess the scale's psychometric properties. Construct validity was assessed based on correlations between mastery and caregiver burden, depression, and quality of life.

Background: The number of women of childbearing age with Type 2 diabetes(T2DM) is increasing, and they now account for > 50% of pregnancies in women with pre-existing diabetes. Diabetes pregnancies without adequate pre-pregnancy care have higher risk for poor outcomes (miscarriages, birth-defects, stillbirths) and are associated with increased complications (caesarean deliveries, macrosomic babies, neonatal intensive-care admissions). The risks and costs of these pregnancies can be reduced with pregnancy preparation (HbA1c, ≤ 6.

Objectives: To analyse the empirical support of the functional ability concept in the healthy ageing framework developed by the WHO in a sample of the Philippine older population. According to this framework, environmental factors may enhance or hinder functional ability, which is the person's ability to do what they value, broadly represented by subjective well-being. Moreover, this network of relationships may be moderated by personal characteristics such as gender.

Background: A few instruments that identify and valuate health states are based on the International Classification of Functioning, Disability and Health States of the World Health Organization. One of them is the Health State Description (HSD) questionnaire first used in the World Health Survey (WHS) initiative (HSD-WHS), whose psychometric properties have not been evaluated in Chile. Additionally, the use of latent variables for the valuation process of health states has been scarcely investigated in the context of population health metrics.

Background: Many patients prefer to avoid hospital-based care towards the end of life, yet hospitalisation is common and more likely for people with low socioeconomic position. The reasons underlying this socioeconomic inequality are not well understood. This study investigated health, service access, and social support as potential mediating pathways between socioeconomic position and receipt of hospital-based care towards the end of life.

Aim: This study aimed to investigate the relationships between multimorbidity, healthy aging and mortality.

Methods: Using data from 9171 individuals aged ≥50 years at wave 2 and mortality data at wave 5 of the English Longitudinal Study of Aging, a multiple linear regression model and a Cox proportional hazards model were used to investigate how multimorbidity patterns (identified as cardiorespiratory/arthritis/cataracts, metabolic and relatively healthy) were associated with a composite index of healthy aging (derived from 41 intrinsic capacity and functional ability items) and with mortality.

Results: A total of 60% of the sample with multimorbidity had a moderate or high level of healthy aging.

Background: Several diagnostic criteria for major depressive disorder (MDE) overlap with those of Chronic Fatigue Syndrome (CFS). Furthermore, atypical MDE (A-MDE), a subtype of MDE characterised by profound fatigue and which has frequently been linked with CFS, exhibits similar low cortisol levels to CFS. However, this result has been only found in specimens designed for measuring acute cortisol levels.
