Emerging multidrug-resistant organisms (MDROs), such as carbapenem-resistant Enterobacterales (CRE), can spread rapidly in a region. Facilities that care for high-acuity patients with longer stays may have a disproportionate impact on this spread.

We assessed the impact of implementing preventive interventions, directed at a subset of facilities, on regional prevalence.

We developed a deterministic compartmental model, parametrized using CRE and patient transfer data. The model included the community and healthcare facilities within a US state. Individuals may be either susceptible or infectious with CRE. Individuals determined to be infectious through admission screening, periodic prevalence surveys (PPSs), or interfacility communication were placed in a state of lower transmissibility if enhanced infection prevention and control (IPC) practices were in place at a facility.

Intervention bundles that included PPS and enhanced IPC practices at ventilator-capable skilled nursing facilities (vSNFs) and long-term acute-care hospitals (LTACHs) had the greatest impact on regional prevalence. The benefits of including targeted admission screening in acute-care hospitals, LTACHs, and vSNFs, and improved interfacility communication were more modest. Daily transmissions in each facility type were reduced following the implementation of interventions primarily focused at LTACHs and vSNFs.

Our model suggests that interventions that include screening to limit unrecognized MDRO introduction to, or dispersal from, LTACHs and vSNFs slow regional spread. Interventions that pair detection and enhanced IPC practices within LTACHs and vSNFs may substantially reduce the regional burden.

Psychotic experiences (PE) occur most often in childhood, at the same age many mental disorders (MD) develop. There is growing evidence that those who report PE and MD show poorer health outcomes. If this occurs in psychosocial outcomes e.g. self-esteem, stress, mental distress, or social support, is under examined. Attachment anxiety and avoidance are the dimensions of attachment, which is hypothesized to develop in infancy as a mechanism for interpersonal relationships in times of need.

To examine the role of transient childhood PE in adult psychosocial outcomes, in those with and without MD. Additionally, to examine if the dimensions of attachment attenuate this model.

One hundred and three participants attended baseline (age 11 – 13) and 10-year follow-up. PE and MD were collected using the Schedule for Affective Disorders and Schizophrenia for School-aged Children, Present & Lifetime Version. Attachment and outcomes were collected using self-report measures. Analysis compared those with PE, MD and PE and MD, to healthy controls.

PE in childhood was associated with lower self-esteem and lower perceived social support from friends. Lower self-esteem in adulthood was more pronounced in those reporting PE and MD, and was additionally associated with stress in relationships, daily life, and mental distress. Childhood MD without PE was not significantly associated with any psychosocial outcomes. Attachment dimensions significantly attenuated the relationship between PE and self-esteem.

This paper illustrates the significant association of childhood PE on adult outcomes, independent of the effect of co-occurring MD, and demonstrate attachment dimensions role in this model.

No significant relationships.

Psychotic experiences (PEs) are relatively common in childhood and adolescence and are associated with increased risk of functional issues and psychiatric illness in young adulthood, and PEs that recur are associated with increased risk of poorer psychiatric and functional outcomes. Childhood adversity is a well-established risk factor for PEs. The aim of this study was to investigate (1) the relationship between childhood adversity and recurring PEs in adolescence and (2) candidate mediators of that relationship.

We used data from Cohort ‘98 of the Growing Up in Ireland study (n = 6039) at three time points (ages 9, 13 and 17) to investigate the relationship between childhood adversity (parent-reported at age 9), recurring PEs (measured using a subset of the Adolescent Psychotic-like Symptoms Screener at ages 13 and 17). The mediating roles of parent–child relationship, internalising and externalising difficulties, self-concept, physical activity, dietary quality, perceived neighbourhood safety and friendship quantity were investigated using the KHB path decomposition method.

Childhood adversity was associated with an increased risk of recurring PEs with a population attributable fraction of 23%. Internalising difficulties and self-concept explained 13% of the relationship between childhood adversity and PEs suggesting a partial mediation. A significant direct effect remained between childhood adversity and recurring PEs.

The established relationship between childhood adversity and PEs may be mainly driven by the relationship between childhood adversity and recurring PEs. Internalising difficulties and self-concept together mediate part of the relationship between childhood adversity and recurring PEs.

People living with dementia (PLWD) in residential aged care homes (RACHs) are frequently prescribed psychotropic medications due to the high prevalence of neuropsychiatric symptoms, also known as behaviors and psychological symptoms of dementia (BPSD). However, the gold standard to support BPSD is using psychosocial/non-pharmacological therapies.

This study aims to describe and evaluate services and neuropsychiatric outcomes associated with the provision of psychosocial person-centered care interventions delivered by national multidisciplinary dementia-specific behavior support programs.

A 2-year retrospective pre-post study with a single-arm analysis was conducted on BPSD referrals received from Australian RACHs to the two Dementia Support Australia (DSA) programs, the Dementia Behavior Management Advisory Service (DBMAS) and the Severe Behavior Response Teams (SBRT). Neuropsychiatric outcomes were measured using the Neuropsychiatric Inventory (NPI) total scores and total distress scores. The questionnaire version “NPI-Q” was administered for DBMAS referrals whereas the nursing home version “NPI-NH” was administered for SBRT referrals. Linear mixed effects models were used for analysis, with time, baseline score, age, sex, and case length as predictors. Clinical significance was measured using Cohen’s effect size (d; ≥0.3), the mean change score (MCS; 3 points for the NPI-Q and 4 points for the NPI-NH) and the mean percent change (MPC; ≥30%) in NPI parameters.

A total of 5,914 referrals (55.9% female, age 82.3 ± 8.6 y) from 1,996 RACHs were eligible for analysis. The most common types of dementia were Alzheimer’s disease (37.4%) and vascular dementia (11.7%). The average case length in DSA programs was 57.2 ± 26.3 days. The NPI scores were significantly reduced as a result of DSA programs, independent of covariates. There were significant reductions in total NPI scores as a result of the DBMAS (61.4%) and SBRT (74.3%) programs. For NPI distress scores, there were 66.5% and 69.1% reductions from baseline for the DBMAS and SBRT programs, respectively. All metrics (d, MCS, MPC) were above the threshold set for determining a clinically significant effect.

Multimodal psychosocial interventions delivered by DSA programs are clinically effective as demonstrated by positive referral outcomes, such as improved BPSD and related caregiver distress.

Hallucinations and delusions that occur in the absence of a psychotic disorder are common in children and adolescents. Longitudinal phenomenological studies exploring these experiences are notably lacking. The objective of the current paper was to explore the phenomenology and characteristics of hallucinations and delusions from early adolescence to early adulthood.

Participants were 17 young people aged 18–21 years from the general population, all of whom had a history of childhood hallucinations and/or delusions. Longitudinal data on the phenomenological characteristics and attributions of reported hallucinatory and delusional phenomena spanning nine years were explored using content analysis.

Hallucinatory and delusional phenomena were transient for two-thirds of the sample. The remaining one-third reported reoccurring hallucinatory and delusional phenomena into early adulthood. In those, two typologies were identified: (1) Paranormal typology and (2) Pathological typology. The former was characterised by hallucinatory and delusional phenomena that were exclusively grounded in subcultural paranormal or spiritual belief systems and not a source of distress. The latter was characterised by delusion-like beliefs that were enmeshed with individuals’ mood states and a source of distress. The perceived source, the subcultural context and how young people appraised and integrated their experiences differentiated the Paranormal and Pathological typologies.

Not all hallucinatory and delusion-like experiences are psychotic-like in nature. To reliably differentiate between pathological and non-pathological hallucinations and delusions, assessments need to explore factors including the phenomenology of individuals’ experiences, how people make sense and appraise them, and the subcultural contexts within which they are experienced.

Abnormal body mass index (BMI) has been associated with development of psychopathology. This association in children is well documented, for both overweight and underweight children. However, the association between change in BMI and the development of psychopathology has been less investigated.

To investigate the association between change in BMI between childhood and adolescence and psychopathology in adolescence.

Data from the Growing Up in Ireland cohort were used. We investigated the ’98 cohort (also known as the child cohort) at age 9/13. BMI, defined using internationally recognised definitions as underweight, healthy or overweight, was used as the exposure, and abnormal Strength and Difficulties Questionnaire scores were used as the outcome. Logistic regression was undertaken for the analysis. All analyses were adjusted for confounders.

A change to overweight from healthy BMI was significantly associated with increased risk of psychopathology (adjusted OR 1.66; 95% CI 1.19–2.32). Both change from underweight to healthy (adjusted OR 0.12; 95% CI 0.03–0.43) or from overweight to healthy (adjusted OR 0.47; 95% CI 0.79–0.8) was associated with a significantly reduced risk of developing psychopathology.

As a child’s BMI returns to within the healthy range, their risk of adolescent psychopathology is reduced. Interventions to restore healthy BMI, in both underweight and overweight, children may reduce their risk of adolescent psychopathology.

Often referred to as psychotic experiences, unusual perceptual experiences, thoughts and beliefs (UPTBs) are not uncommon in youth populations. Phenomenological studies of these experiences are lacking. This study aimed to (1) describe the phenomenological characteristics of UPTBs in a sample of young adolescents and (2) explore how young people made sense of those experiences.

Participants were 53 young people aged 11–13 years from a population-based study of mental health. All met criteria for UPTBs following clinical interviews as part of the study. Documentary data on UPTBs in the form of transcribed notes, recorded during clinical interviews, were analysed using content analysis. Data on UPTBs were coded, organised into categorical themes and quantified using descriptive statistics. Qualitative themes on how participants made sense of their experiences were identified.

Participants reported UPTBs across four domains: auditory verbal, auditory non-verbal, non-auditory perceptual experiences and unusual thoughts and beliefs. UPTBs were phenomenologically rich and diverse. Young people sought to make sense of their experiences in multiple ways: normalising them, externalising them by attributing them to paranormal entities and distancing them from psychiatric explanations. Uncertainty about the source of UPTBs was identified as a superordinate theme.

Findings from this study offer new insights into the phenomenological qualities and characteristics of UPTBs in young adolescents. They also reveal that early adolescents may not make sense of their experiences within a psychiatric framework. These findings highlight the need to develop a more phenomenologically sensitive and nuanced approach to studying UPTBs in young people.

Cognitive impairment impacts on patient outcomes [1] but is under-recognised in acute hospitals [2]. Data on rates and degree of impairment among hospital inpatients remain sparse. This information is vital for strategic planning of health services as the European population ages.

To examine the rates and degree of cognitive impairment among patients aged 65 and older who were admitted to an acute general hospital and to assess its impact on patient outcomes.

All patients aged over 65 who were admitted over a 2-week period were invited to participate. Those who met the inclusion criteria were screened for delirium then underwent a cognitive screening battery. Normative values for age and level of education were obtained from the TILDA study [3]. Demographic and outcome data were obtained from medical records.

One hundred and forty-eight patients underwent cognitive screening. Thirty-nine over 148 (26%) met the DSM-IV criteria for dementia of whom only 16 (41%) had a previously-documented impairment. Thirty over 148 (20%) had evidence of cognitive impairment that did not meet criteria for dementia, only 3 (10%) of whom were previously documented. Seventy-three over 148 (49%) were normal. Six over 148 (4%) were not classifiable. The impact of cognitive status on length of hospital stay, number of readmissions in 6 months and discharge destination was investigated. Impact on length of stay was significant (P = 0.017) but significance was not achieved against number of readmissions or discharge destination.

Cognitive impairment is pervasive and under-recognised in the acute hospital and impacts on length of hospital stay. Longer interval analysis is necessary to investigate further implications.
