Existing systematic reviews have suggested mixed effects of the Covid pandemic on the mental health of children and young people. Those with pre-existing mental health and neurodevelopmental conditions have been suggested to be disproportionately affected, but this has not been meta-analysed. Most reviews of studies in clinical populations to date only include cross-sectional studies during the first lockdown or longitudinal cohorts up to early 2021, which limits our understanding of causality and long-term effects. To our knowledge, this is the first systematic review and meta-analysis to examine the longitudinal impact of the pandemic on the mental health of children and young people with pre-existing mental health and neurodevelopmental conditions.

To compare 1) mental health pre versus during Covid, and 2) mental health during Covid.

Medline, Embase, APA PsycInfo, and Global Health databases were searched up to August 2023. Longitudinal studies reporting mental health outcomes in children and young people (≤18 years old) with pre-Covid mental health and/or neurodevelopmental conditions were included. Cohorts were deemed eligible if children and young people were diagnosed using a diagnostic assessment, scored above clinical threshold on validated measures, or attended mental health services pre-Covid. Outcomes included internalising, externalising, and other symptoms. Studies were narratively synthesised by symptom category and meta-analyses performed where number of studies reporting the same outcomes were sufficient (≥5).

6,083 records were identified and 21 studies (N=2,617) were included. These widely differed in country, setting, diagnosis, outcome, and timepoints under study. The narrative synthesis highlighted mixed findings in mental health changes during the pandemic for all three symptom categories showing increases, reductions, and no changes. Only studies reporting changes in internalising symptoms pre- versus during the pandemic were in sufficient number to be amenable to meta-analysis.

Our findings suggest the pandemic’s impact on the mental health of children and young people with pre-existing mental health and neurodevelopmental conditions were complex and varied. We highlight an urgent need for longitudinal Covid research on long-term mental health outcomes in this vulnerable group. Understanding risk factors and longitudinal trajectories is warranted to guide clinical practice and policy.

The Northern Territory (NT) has Australia’s highest mental health burden. It has a diverse and transient population, including Aboriginal and Torres Strait Islander people and various multicultural communities. While peer support has been widely used nationwide, in the NT, peer support is poorly implemented in psychosocial support activities.

The NT Lived Experience Network (NTLEN), in allyship with a team of researchers from Flinders University, has secured multiple fundings aimed to develop, implement, and evaluate a peer education and recovery program called Recovery Together (RT) for individuals with mental health and alcohol and drug use issues and related challenges.

The suitable evaluation approach was co-designed with live experience representatives from NTLEN and other local key stakeholders. It applied a mixed-method approach, including pre and post-program surveys (n=64) and individual interviews with program participants and the program delivery team (n=32). The evaluation findings were also informed by data collected by NTLEN via feedback forms n=38). We also used a co-design approach to develop survey instruments to ensure they were strengths-based and recovery-oriented.

Participants reported poor and fair self-perceived health, high stress levels, dissatisfaction with their relationships and relatively low recovery scores, which showed improvements at post-program completion. They discussed their journeys in the interviews and shared their experiences with local mental health services and the Recovery Together program. Many expressed that mental health professionals are not necessarily the care providers they feel comfortable engaging with. However, they described their experience with the peer program as highly positive, empowering, safe, non-judgmental, and beneficial, satisfying their support needs. The program gave them hope and tools to manage their mental health challenges and opportunities to gain insight into non-clinical aspects of recovery. Participants conceptualised personal recovery in their own words and described the facilitators and barriers to their recovery. They emphasised that recovery is being empowered, strong within themselves and the leader of their journey, living their best possible life, understanding themselves, having the necessary knowledge about mental health, and looking forward in a hopeful way.

Our findings highlighted the demand and need for ongoing delivery of the RT program in the NT, which was highly effective in supporting personal recovery, addressing the service delivery gap and complementing the available clinical and mental health practices. They also showed the importance of providing recovery-oriented and trauma-informed education for medical and mental health professionals.

Anxiety disorders are the most frequently diagnosed psychiatric conditions in children and adolescents. Cognitive behavioural therapy (CBT) is a well-established and effective treatment for anxiety and related disorders across the lifespan. Expectations of psychotherapy have been demonstrated to affect outcomes, yet there is sparse existing literature on adolescent patient and parent perspectives of CBT prior to engagement with treatment.

This study aimed to qualitatively explore the expectations and perceptions of CBT for anxiety and related disorders among adolescent patients and parents.

Fourteen adolescent patients and 16 parents participated in semi-structured individual interviews or focus groups consisting of 2–3 participants. Interview transcripts were analysed using inductive analysis.

Three themes were identified: worries about CBT, expectations and knowledge of the CBT process, and the role of parents and families. Overall, we found that adolescents and parents had generally positive views of CBT. The outset of CBT saw adolescents and parents express concern about stigma as well as the ambiguity of CBT. Parents continued to express a lack of understanding of what CBT entailed during their child’s treatment course.

These results suggest that both adolescents and parents would benefit from early discussion and reinforcement of expectations for CBT treatment. Further research efforts are warranted and should be directed towards determining appropriate expectations for parental involvement in a child’s CBT course and effective communication of treatment expectations to both adolescents and parents.

Behavioural patterns are important in understanding the synergistic effect of multiple health behaviours on childhood adiposity. Most previous evidence assessing associations between patterns and adiposity were cross-sectional and investigated two or three behaviour domains within patterns. This study aimed to identify behavioural patterns comprising four behaviour domains and investigate associations with adiposity risk in children.

Parent-report and accelerometry data were used to capture daily dietary, physical activity, sedentary behaviour and sleep data. Variables were standardised and included in the latent profile analysis to derive behavioural patterns. Trained researchers measured children’s height, weight and waist circumference using standardised protocols. Associations of patterns and adiposity measures were tested using multiple linear regression.

Melbourne, Australia.

A total of 337 children followed up at 6–8 years (T2) and 9–11 years (T3).

Three patterns derived at 6–8 years were broadly identified to be healthy, unhealthy and mixed patterns. Patterns at 9–11 years were dissimilar except for the unhealthy pattern. Individual behaviours characterising the patterns varied over time. No significant cross-sectional or prospective associations were observed with adiposity at both time points; however, children displaying the unhealthy pattern had higher adiposity measures than other patterns.

Three non-identical patterns were identified at 6–8 and 9–11 years. The individual behaviours that characterised patterns (dominant behaviours) at both ages are possible drivers of the patterns obtained and could explain the lack of associations with adiposity. Identifying individual behaviour pattern drivers and strategic intervention are key to maintain and prevent the decline of healthy patterns.

Prospective audit and feedback (PAF) is an established practice in critical care settings but not in surgical populations. We pilot-tested a structured face-to-face PAF program for our acute-care surgery (ACS) service.

This was a mixed-methods study. For the quantitative analysis, the structured PAF period was from August 1, 2017, to April 30, 2019. The ad hoc PAF period was from May 1, 2019, to January 31, 2021. Interrupted time-series segmented negative binomial regression analysis was used to evaluate change in antimicrobial usage measured in days of therapy per 1,000 patient days for all systemic and targeted antimicrobials. Secondary outcomes included C. difficile infections, length of stay and readmission within 30 days. Each secondary outcome was analyzed using a logistic regression or negative binomial regression model. For the qualitative analyses, all ACS surgeons and trainees from November 23, 2015, to April 30, 2019, were invited to participate in an email-based anonymous survey developed using implementation science principles. Responses were measured using counts.

In total, 776 ACS patients were included in the structured PAF period and 783 patients were included in the in ad hoc PAF period. No significant changes in level or trend for antimicrobial usage were detected for all and targeted antimicrobials. Similarly, no significant differences were detected for secondary outcomes. The survey response rate was 25% (n = 10). Moreover, 50% agreed that PAF provided them with skills to use antimicrobials more judiciously, and 80% agreed that PAF improved the quality of antimicrobial treatment for their patients.

Structured PAF showed clinical outcomes similar to ad hoc PAF. Structured PAF was well received and was perceived as beneficial by surgical staff.

There is emerging evidence of heterogeneity within treatment-resistance schizophrenia (TRS), with some people not responding to antipsychotic treatment from illness onset and a smaller group becoming treatment-resistant after an initial response period. It has been suggested that these groups have different aetiologies. Few studies have investigated socio-demographic and clinical differences between early and late onset of TRS.

This study aims to investigate socio-demographic and clinical correlates of late-onset of TRS.

Using data from the electronic health records of the South London and Maudsley, we identified a cohort of people with TRS. Regression analyses were conducted to identify correlates of the length of treatment to TRS. Analysed predictors include gender, age, ethnicity, positive symptoms severity, problems with activities of daily living, psychiatric comorbidities, involuntary hospitalisation and treatment with long-acting injectable antipsychotics.

We observed a continuum of the length of treatment until TRS presentation. Having severe hallucinations and delusions at treatment start was associated shorter duration of treatment until the presentation of TRS.

Our findings do not support a clear cut categorisation between early and late TRS, based on length of treatment until treatment resistance onset. More severe positive symptoms predict earlier onset of treatment resistance.

Ethnic disparities in treatment with clozapine, the antipsychotic recommended for treatment-resistant schizophrenia (TRS), have been reported. However, these investigations frequently suffer from potential residual confounding. For example, few studies have restricted the analyses to TRS samples and none has controlled for benign ethnic neutropenia.

This study investigated if service-users’ ethnicity influenced clozapine prescription in a cohort of people with TRS.

Information from the clinical records of South London and Maudsley NHS Trust was used to identify a cohort of service-users with TRS between 2007 and 2017. In this cohort, we used logistic regression to investigate any association between ethnicity and clozapine prescription while adjusting for potential confounding variables, including sociodemographic factors, psychiatric multimorbidity, substance use, benign ethnic neutropenia, and inpatient and outpatient care received.

We identified 2239 cases that met the criteria for TRS. Results show that after adjusting for confounding variables, people with Black African ethnicity had half the odds of being treated with clozapine and people with Black Caribbean or Other Black background had about two-thirds the odds of being treated with clozapine compared White British service-users. No disparities were observed regarding other ethnic groups, namely Other White background, South Asian, Other Asian, or any other ethnicity.

There was evidence of inequities in care among Black ethnic groups with TRS. Interventions targeting barriers in access to healthcare are recommended.

To describe the evolution of respiratory antibiotic prescribing during the coronavirus disease 2019 (COVID-19) pandemic across 3 large hospitals that maintained antimicrobial stewardship services throughout the pandemic.

Retrospective interrupted time-series analysis.

A multicenter study was conducted including medical and intensive care units (ICUs) from 3 hospitals within a Canadian epicenter for COVID-19.

Interrupted time-series analysis was used to analyze rates of respiratory antibiotic utilization measured in days of therapy per 1,000 patient days (DOT/1,000 PD) in medical units and ICUs. Each of the first 3 waves of the pandemic were compared to the baseline.

Within the medical units, use of respiratory antibiotics increased during the first wave of the pandemic (rate ratio [RR], 1.76; 95% CI, 1.38–2.25) but returned to the baseline in waves 2 and 3 despite more COVID-19 admissions. In ICU, the use of respiratory antibiotics increased in wave 1 (RR, 1.30; 95% CI, 1.16–1.46) and wave 2 of the pandemic (RR, 1.21; 95% CI, 1.11–1.33) and returned to the baseline in the third wave, which had the most COVID-19 admissions.

After an initial surge in respiratory antibiotic prescribing, we observed the normalization of prescribing trends at 3 large hospitals throughout the COVID-19 pandemic. This trend may have been due to the timely generation of new research and guidelines developed with frontline clinicians, allowing for the active application of new research to clinical practice.

We evaluated the impact of introducing a mandatory indication field into electronic order entry for targeted antibiotics in adult inpatients.

Retrospective, before-and-after trial.

A 400-bed community hospital.

All adult electronic intravenous (IV) and enteral orders for targeted antibiotics (moxifloxacin, ciprofloxacin, clindamycin, vancomycin, and metronidazole) had a mandatory indication field added. Control antibiotics (amoxicillin-clavulanate, ceftriaxone and piperacillin-tazobactam) were chosen to track shifts in antibiotic prescribing due to the introduction of mandatory indication field.

Descriptive statistics were used to summarize the primary outcome, measured in Defined Daily Doses (DDD) per 1000 patient days (PD). Interrupted time-series (ITS) analysis was performed to compare levels and trends in antibiotic usage of targeted and control antibiotics during 24 months before and after the intervention. Additionally, a descriptive analysis of mandatory indication fields for targeted antibiotics in the postintervention period was conducted.

In total, 4,572 study antibiotic orders were evaluated after the intervention. Preset mandatory indications were selected for 30%–55% of orders. There was decreased usage of targeted antibiotics (mean, 92.02 vs 72.07 DDD/1000-PD) with increased usage of control antibiotics (mean, 102.73 vs 119.91 DDD/1000-PD). ITS analysis showed no statistically significant difference in overall antibiotic usage before and after the intervention for all targeted antibiotics.

This study showed moderate use of preset mandatory indications, suggesting that the preset list of indications can be optimized. There was no impact on overall antibiotic usage with the use of mandatory indications. More prospective research is needed to study the utility of this intervention in different contexts.
