Domestic abuse often begins or escalates during the perinatal period, increasing the risk of adverse pregnancy outcomes and death of the woman and infant. The hidden nature of domestic abuse, compounded by barriers to disclosure, means many clinicians are likely to have unknowingly encountered a patient who is being abused and missed a vital opportunity for intervention. This educational article presents the experience of a woman who was abused during pregnancy. It describes how to facilitate a disclosure and conduct an assessment and illustrates safeguarding duties alongside interventions.

Historically, attention-deficit hyperactivity disorder (ADHD) was conceptualised as a disorder of childhood that gradually improved and diminished as individuals transitioned to adulthood. Over the past decade, several studies have been published describing a cohort of adolescents with a childhood diagnosis of ADHD experiencing a continuity of ADHD symptoms into adulthood. Untreated ADHD in adults is associated with personal relationship difficulties, educational and occupational underachievement, comorbid mental health problems, substance misuse, and increased rates of road traffic accidents and criminality. These result in an increased economic burden and broader public health challenges. This review outlines the current framework and stage of development of ADHD services for adults in the Republic of Ireland.

Aims and method: The prevalence of delaying psychiatric care until the patient has received 'medical clearance', and the definitions and understanding of 'medical clearance' terminology by relevant clinicians, are largely unknown. In a service evaluation of adult liaison psychiatry services across England, we explore the prevalence, definitions and understanding of 'medical clearance' terminology in three parallel studies: (a) an analysis of trust policies, (b) a survey of liaison psychiatry services and (c) a survey of referring junior doctors. Content and thematic analyses were performed.
Results: 'Medical clearance' terminology was used in the majority of trust policies, reported as a referral criterion by many liaison psychiatry services and had been encountered by most referring doctors. 'Medical clearance' was identified as a common barrier to liaison psychiatry referral. Terms were inconsistently used and poorly defined.
Clinical implications: Many liaison psychiatry services seem not to comply with guidance promoting parallel assessment. This may affect parity of physical and mental healthcare provision.

Background: Schizophreniform disorders tend to have an early onset. Early intervention in psychosis (EIP) services aim to provide early treatment, reduce long-term morbidity and improve social functioning. In 2016, changes to mental health policy in England mandated that the primarily youth-focused model should be extended to an ageless one, to prevent ageism; however, this was without strong research evidence.
Aims and method: An inner-city London EIP service compared sociodemographic and clinical factors between the under-35 years and over-35 years caseload cohorts utilising the EIP package following the implementation of the ageless policy.
Results: Both groups received similar care, despite the younger group having significantly more clinical morbidity and needs.
Clinical implications: Our results may indicate that service provisions are being driven by policy rather than clinical needs, potentially diverting resources from younger patients. These findings have important implications for future provision of EIP services and would benefit from further exploration.

Aims and method: The study evaluated a package of measures to improve sleep on psychiatric wards admitting patients from children and young people's services (CYPS). Sleep disturbance has significant impact on adolescent mental health, and in-patient wards can directly cause sleep disturbance, independent of the problem that led to admission. We developed a CYPS-specific package (TeenSleepWell) that promoted a better sleep environment, enhanced staff education about sleep, screened for sleep disorders, and raised awareness of benefits and side-effects of hypnotics. This included personalised sleep care plans that allowed a protected 8 h sleep period when safe.
Results: Evaluation over 2 years showed enhanced in-patient care: 57% of patients were able to have a protected sleep period. There was no increase in adverse events and there was a decrease in hypnotics issued.
Clinical implications: Improving sleep during in-patient CYPS admissions is possible and personalised sleep care plan should be a care standard.

This paper presents an emerging understanding of the psychodynamics of suicide loss, derived from over 1500 accounts of suicide bereavement shared by families, friends and clinicians. It identifies clear patterns in the responses of the bereaved, particularly the formation of delusional narratives that often place them at the centre of blame for the death. These narratives have a profound impact on well-being, increase the risk of mental illness and elevate the likelihood of death by suicide. They not only cause harm to the bereaved but also permeate and distort our systemic and societal responses. Understanding why suicide unleashes such painful and dangerous forces helps mitigate the widespread harm and distress that often follows such a death. This knowledge also enables us to effectively and compassionately support those bereaved.

Aims and method: This cross-sectional study, carried out from 2021 to 2022, investigated the factors associated with domestic violence in 400 Brazilian pregnant women during the COVID-19 pandemic. Violence was assessed with the World Health Organization's Violence Against Women questionnaire and the Abuse Assessment Screen. Demographic, socioeconomic, obstetric, lifestyle and mental health data were collected.
Results: Violence at any time in their lives was reported by 52.2% of the women, and psychological violence was the most prevalent type (19.5%). Violence was associated with being single and mental health changes. Pregnant women exposed to any lifetime violence and psychological violence were, respectively, 4.67 and 5.93 times more likely to show mental health changes compared with women with no reported violence.
Clinical implications: Training health professionals involved in prenatal care in the early detection of single women and women with mental health changes could be important in preventing domestic violence.

Aims and method: The COVID-19 pandemic prompted a surge in adolescent eating disorders and rapid changes in the delivery of intensive community treatments. This study investigates the modification from a group-based day programme to an intensive family treatment approach. A retrospective chart review was performed on data from 190 patients who accessed the intensive service for anorexia nervosa in the past 6 years. Outcomes from the traditional model were compared with the new intensive family model, namely length of admission, percentage median body mass index difference and transfers to in-patient services.
Results: There was a significant reduction in the length of intensive treatment (from 143.19 to 97.20 days). The number of transfers to specialist eating disorder in-patient services also significantly reduced, and is decreasing year on year.
Clinical implications: The findings hold particular relevance as intensive services for adolescent eating disorders continue to be established within health services, with no clear unified approach to treatment.

Aims and method: Workplace violence and aggression toward healthcare staff has a significant impact on the individual, causing self-blame, isolation and burnout. Timely and appropriate support can mitigate harm, but there is little research into how this should be delivered. We conducted multi-speciality peer groups for London doctors in postgraduate training (DPT), held over a 6-week period. Pre- and post-group burnout questionnaires and semi-structured interviews were used to evaluate peer support. Thematic analysis and descriptive statistical methods were used to describe the data.
Results: We found four themes: (a) the experience and impact of workplace violence and aggression on DPT, (b) the experience of support following incidents of workplace violence and aggression, (c) the impact and experience of the peer groups and (d) future improvements to support. DPTs showed a reduction in burnout scores.
Clinical implications: Peer groups are effective support for DPT following workplace violence and aggression. Embedding support within postgraduate training programmes would improve access and availability.
