Electronic health records (EHRs), increasingly available in low- and middle-income countries (LMICs), provide an opportunity to study transdiagnostic features of serious mental illness (SMI) and its trajectories.

Characterise transdiagnostic features and diagnostic trajectories of SMI using an EHR database in an LMIC institution.

We conducted a retrospective cohort study using EHRs from 2005–2022 at Clínica San Juan de Dios Manizales, a specialised mental health facility in Colombia, including 22 447 patients with schizophrenia (SCZ), bipolar disorder (BPD) or severe/recurrent major depressive disorder (MDD). Using diagnostic codes and clinical notes, we analysed the frequency of suicidality and psychosis across diagnoses, patterns of diagnostic switching and the accumulation of comorbidities. Mixed-effect logistic regression was used to identify factors influencing diagnostic stability.

High frequencies of suicidality and psychosis were observed across diagnoses of SCZ, BPD and MDD. Most patients (64%) received multiple diagnoses over time, including switches between primary SMI diagnoses (19%), diagnostic comorbidities (30%) or both (15%). Predictors of diagnostic switching included mentions of delusions (odds ratio = 1.47, 95% CI 1.34–1.61), prior diagnostic switching (odds ratio = 4.01, 95% CI 3.7–4.34) and time in treatment, independent of age (log of visit number; odds ratio = 0.57, 95% CI 0.54–0.61). Over 80% of patients reached diagnostic stability within 6 years of their first record.

Integrating structured and unstructured EHR data reveals transdiagnostic patterns in SMI and predictors of disease trajectories, highlighting the potential of EHR-based tools for research and precision psychiatry in LMICs.

To evaluate the impact of a mobile-app-based central line-associated bloodstream infection (CLABSI) prevention program in oncology clinic patients with peripherally inserted central catheters (PICCs).

Pre-post prospective cohort study with baseline (July 2015–December 2016), phase-in (January 2017–April 2017), and intervention (May 2017–November 2018). Generalized linear mixed models compared intervention with baseline frequency of localized inflammation/infection and dressing peeling. Cox proportional hazards models compared days-to-removal of lines with localized inflammation/infection. Chi-square test compared bacteremia rates before and after intervention.

CLABSI prevention program consisting of an actionable scoring system for identifying insertion site infection/inflammation coupled with a mobile-app enabling photo-assessments and automated physician alerting for remote response.

We completed 5,343 assessments of 569 PICCs in 401 patients (baseline: 2,924 assessments, 300 PICCs, 216 patients; intervention: 2,419 assessments, 269 PICCs, 185 patients). The intervention was associated with a 92% lower likelihood of having a dressing with peeling (OR 0.08, 95%CI 0.04-0.17, P < 0.001), 53% lower local inflammation/infection (OR 0.47, 95%CI 0.27-0.84, P < 0.011), and 24% (non-significant) lower CLABSI rates (P = .63). Physician mobile-app alerting and response enabled 80% lower risk of lines remaining in place after inflammation/infection was identified (HR 0.20, 95%CI:0.14-0.30, P < 0.001) and 85% faster removal of infected lines from mean (SD) 11.1 (9.7) to 1.7 (2.4) days.

A mobile-app-based CLABSI prevention program decreased frequency of inflamed/infected central line insertion sites and increased speed of removal when inflammation/infection was found.

Interprofessional teams in the pediatric cardiac ICU consolidate their management plans in pre-family meeting huddles, a process that affects the course of family meetings but often lacks optimal communication and teamwork.

Cardiac ICU clinicians participated in an interprofessional intervention to improve how they prepared for and conducted family meetings. We conducted a pretest–posttest study with clinicians participating in huddles before family meetings. We assessed feasibility of clinician enrollment, assessed clinician perception of acceptability of the intervention via questionnaire and semi-structured interviews, and impact on team performance using a validated tool. Wilcoxon rank sum test assessed intervention impact on team performance at meeting level comparing pre- and post-intervention data.

Totally, 24 clinicians enrolled in the intervention (92% retention) with 100% completion of training. All participants recommend cardiac ICU Teams and Loved ones Communicating to others and 96% believe it improved their participation in family meetings. We exceeded an acceptable level of protocol fidelity (>75%). Team performance was significantly (p < 0.001) higher in post-intervention huddles (n = 30) than in pre-intervention (n = 28) in all domains. Median comparisons: Team structure [2 vs. 5], Leadership [3 vs. 5], Situation Monitoring [3 vs. 5], Mutual Support [ 3 vs. 5], and Communication [3 vs. 5].

Implementing an interprofessional team intervention to improve team performance in pre-family meeting huddles is feasible, acceptable, and improves team function. Future research should further assess impact on clinicians, patients, and families.

Improving functioning in adults with major depressive disorder (MDD) and bipolar disorder (BD) is a priority therapeutic objective.

This retrospective post hoc secondary analysis evaluated 108 patients with MDD or BD receiving the antidepressants vortioxetine, ketamine, or infliximab. The analysis aimed to determine if changes in objective or subjective cognitive function mediated the relationship between depression symptom severity and workplace outcomes. Cognitive function was measured by the Perceived Deficits Questionnaire (PDQ-5), the Digit Symbol Substitution Test (DSST), and the Trail Making Test Part B (TMT-B). Depression symptom severity was measured by the Montgomery–Åsberg Depression Rating Scale (MADRS). Workplace function was measured by the Sheehan Disability Scale (SDS) work–school item.

When co-varying for BMI, age, and sex, the association between MADRS and SDS work scores was partially mediated by PDQ-5 total scores and DSST total scores, but not DSST error scores and TMT-B time.

This study was insufficiently powered to perform sub-group analyses to identify distinctions between MDD and BD populations as well as between antidepressant agents.

These findings suggest that cognitive impairment in adults with MDD and BD is a critical mediator of workplace function and reinforces its importance as a therapeutic target.

Head and neck squamous cell carcinomas (HNSCCs) are aggressive tumours lacking a standardised timeline for treatment initiation post-diagnosis. Delays beyond 60 days are linked to poorer outcomes and higher recurrence risk.

A retrospective review was conducted on patients over 18 with HNSCC treated with (chemo)radiation at a rural tertiary care centre (September 2020–2022). Data on patient demographics, oncologic characteristics, treatment details and delay causes were analysed using SPSS.

Out of 93 patients, 35.5% experienced treatment initiation delays (TTIs) over 60 days. Median TTI was 73 days for delayed cases, compared to 41.5 days otherwise. No significant differences in demographics or cancer characteristics were observed between groups. The primary reasons for the delay were care coordination (69.7%) and patient factors (18.2%). AJCC cancer stage showed a trend towards longer delays in advanced stages.

One-third of patients faced delayed TTI, primarily due to care coordination and lack of social support. These findings highlight the need for improved multidisciplinary communication and patient support mechanisms, suggesting potential areas for quality improvement in HNSCC treatment management.

Spinal muscular atrophy (SMA) is a leading genetic cause of infant death and represents a significant burden of care. An improved understanding of the epidemiology of SMA in Canada may help inform strategies to improve the standard of care for individuals living with SMA.

We employed a multisource approach to estimate the minimal incidence and prevalence of 5q SMA and to gain greater insight into recent clinical practices and treatment trends for the Canadian SMA population. Data sources included the Canadian Paediatric Surveillance Program (CPSP), Canadian Neuromuscular Disease Registry (CNDR), and molecular genetics laboratories in Canada.

The estimated annual minimum incidence of 5q SMA was 4.38, 3.44, and 7.99 cases per 100,000 live births in 2020 and 2021, based on CPSP, CNDR, and molecular genetics laboratories data, respectively, representing approximately 1 in 21,472 births (range 12,516–29,070) in Canada. SMA prevalence was estimated to be 0.85 per 100,000 persons aged 0–79 years. Delay in diagnosis exists across all SMA subtypes. Most common presenting symptoms were delayed milestones, hypotonia, and muscle weakness. Nusinersen was the most common disease-modifying treatment received. Most patients utilized multidisciplinary clinics for management of SMA.

This study provides data on the annual minimum incidence of pediatric 5q SMA in Canada. Recent therapeutic advances and newborn screening have the potential to drastically alter the natural history of SMA. Findings underline the importance of ongoing surveillance of the epidemiology and long-term health outcomes of SMA in the Canadian population.

To assess whether measurement and feedback of chlorhexidine gluconate (CHG) skin concentrations can improve CHG bathing practice across multiple intensive care units (ICUs).

A before-and-after quality improvement study measuring patient CHG skin concentrations during 6 point-prevalence surveys (3 surveys each during baseline and intervention periods).

The study was conducted across 7 geographically diverse ICUs with routine CHG bathing.

Adult patients in the medical ICU.

CHG skin concentrations were measured at the neck, axilla, and inguinal region using a semiquantitative colorimetric assay. Aggregate unit-level CHG skin concentration measurements from the baseline period and each intervention period survey were reported back to ICU leadership, which then used routine education and quality improvement activities to improve CHG bathing practice. We used multilevel linear models to assess the impact of intervention on CHG skin concentrations.

We enrolled 681 (93%) of 736 eligible patients; 92% received a CHG bath prior to survey. At baseline, CHG skin concentrations were lowest on the neck, compared to axillary or inguinal regions (P < .001). CHG was not detected on 33% of necks, 19% of axillae, and 18% of inguinal regions (P < .001 for differences in body sites). During the intervention period, ICUs that used CHG-impregnated cloths had a 3-fold increase in patient CHG skin concentrations as compared to baseline (P < .001).

Routine CHG bathing performance in the ICU varied across multiple hospitals. Measurement and feedback of CHG skin concentrations can be an important tool to improve CHG bathing practice.
