Shift-Level Team Familiarity Is Associated with Improved Outcomes in Mechanically Ventilated Adults.

RATIONALE: Organizing intensive care unit (ICU) interprofessional teams is a high priority due to workforce needs, but the role of interprofessional familiarity remains unexplored. OBJECTIVE: Determine if mechanically ventilated patients cared for by teams with greater familiarity have improved outcomes, such as lower mortality, shorter duration of mechanical ventilation (MV), and greater spontaneous breathing trial (SBT) implementation. METHODS: We used electronic health records data of 5 ICUs in an academic medical center to map interprofessional teams and their ICU networks, measuring team familiarity as network coreness and mean team value. We used patient-level regression models to link team familiarity with patient outcomes, accounting for patient/unit factors. We also performed a split-sample analysis by using 2018 team familiarity data to predict 2019 outcomes. MEASUREMENTS: Team familiarity was measured as the average number of patients shared by each clinician with all other clinicians in the ICU (i.e., coreness) and the average number of patients shared by any two members of the team (i.e., mean team value). MAIN RESULTS: Among 4,485 encounters, unadjusted mortality was 12.9%, average duration of MV was 2.32 days and SBT implementation was 89%; average team coreness was 467.2 (SD = 96.15) and average mean team value was 87.02 (SD=42.42). A standard-deviation increase in team coreness was significantly associated with a 4.5% greater probability of SBT implementation, 23% shorter MV duration, and 3.8% lower probability of dying; mean team value was significantly associated with lower mortality. Split-sample results were attenuated but congruent in direction and interpretation. CONCLUSIONS: Interprofessional familiarity was associated with improved outcomes; assignment models that prioritize familiarity might be a novel solution.

Registered Nurses' Well-Being, Michigan, 2022.

Objectives. To examine nurses' well-being and identify individual and workplace factors associated with adverse outcomes. Methods. We administered an e-mail survey to registered nurses in Michigan in March 2022. Outcomes included the Oldenburg Burnout Inventory-Exhaustion scale, self-harm thoughts (yes/no), and overall wellness on a 0 to 10 visual analog scale. Covariates included practice environment, psychological safety, workplace abuse, staffing adequacy, stress coping strategies, and demographics. We examined associations between covariates and exhaustion, thoughts of self-harm (both via logistic regression), and overall wellness (via linear regression). Results. Among surveyed nurses, 93.63% reported significant exhaustion, 9.88% reported self-harm thoughts, and the mean (SD) overall wellness score was 6.2 (2.3). Factors associated with exhaustion included inadequate staffing, lower psychological safety, and younger age. Factors associated with self-harm thoughts included recent workplace physical abuse and younger age. Factors associated with higher wellness scores included employer support, favorable practice environments, higher job satisfaction, and positive coping strategies. Conclusions. Negative well-being outcomes were prevalent among registered nurses and were associated with correctable workplace deficits. Nurses' well-being is a national public health problem that warrants comprehensive interventions at individual, workplace, and community levels.

Effectiveness of take ACTION online naloxone training for law enforcement officers.

BACKGROUND: Training law enforcement officers (LEOs) to administer naloxone is a recommended strategy to reduce overdose deaths in the United States. To achieve this, an evidence-based and scalable naloxone training curriculum that is easy to use and readily scalable is needed. Convenient web-based training is a flexible method for delivering educational interventions particularly for LEOs who have irregular or shifting schedules. This study examined the effectiveness of a comprehensive web-based naloxone training that was created in partnership with LEOs on their knowledge, confidence, and attitudes regarding naloxone. METHODS: From May 2019 to September 2020, five law enforcement departments from Michigan participated in web-based naloxone training. A total of 182 LEOs (77% male) were in the final sample based on matching pre-and post-test surveys. LEOs were assessed on knowledge, confidence, and attitudes towards naloxone. Negative binomial and Poisson regression was conducted to assess associations between knowledge, confidence, and attitudes towards naloxone before and after training. RESULTS: Significant improvements in overdose knowledge and confidence were revealed across all departments with median (IQR) total composite scores for knowledge increasing from 35 (32, 37) to 40 (39, 42) (p < 0.01) and confidence increasing from 18.5 (15, 20) to 20 (20, 25) (p < 0.01). Median (IQR) attitude scores did not change. CONCLUSION: Our web-based naloxone training was effective in improving knowledge and confidence for LEOs but did not significantly improve LEOs attitudes towards naloxone across most departments. The web-based format is readily scalable and quickly disseminated and meets the immediate need for LEO overdose training. Additional intervention is needed to address the negative attitudes of LEOs regarding naloxone.

Tolerability and blinding of high-definition transcranial direct current stimulation among older adults at intensities of up to 4 mA per electrode.

BACKGROUND: Few studies have investigated tolerability, blinding, and double-blinding of High-Definition transcranial Direct Current Stimulation (HD-tDCS) at amplitudes above 2 milliamps (mA). OBJECTIVE: We examined a) tolerability of HD-tDCS during stimulation sessions and b) blinding and double blinding of participants and study team members. METHODS: Data from a mixed neurologic sample of 292 older adults were pooled from 3046 HD-tDCS sessions (2329 active; 717 sham). Per electrode amplitudes ranged from 1 mA to 4 mA with total currents up to 10 mA. Participants completed a standardized sensation (tolerability) questionnaire after each session. Participants and study team members stated whether the participant received active or sham stimulation at the end of various sessions. Data were collapsed into the presence/absence of a symptom due to low rates of positive responding and were analyzed for both differences and bioequivalency. RESULTS: There were no safety-related adverse events. HD-tDCS was well tolerated with mostly no ("none") or "mild" sensations reported across sessions, regardless of active or sham condition and in both stimulation naïve and experienced participants. There were no significant differences in side effects between active and sham, with some achieving bioequivalence. Tingling and itching were significantly more common after lower (<2 mA) than higher (≥3 mA) amplitude active sessions, while skin redness was significantly more common after higher amplitudes. Blinding was effective at the participant and study team levels. CONCLUSIONS: HD-tDCS was well tolerated with center electrode amplitudes up to 4 mA. The bimodal ramp-up/down format of the sham was effective for blinding. These results support higher scalp-based amplitudes that enable greater brain-based current intensities in older adults.

Patterns and Correlates of Nurse Departures From the Health Care Workforce: Results From a Statewide Survey.

BACKGROUND: Health care executives and policymakers have raised concerns about the adequacy of the US nursing workforce to meet service demands. Workforce concerns have risen given the SARS-CoV-2 pandemic and chronically poor working conditions. There are few recent studies that directly survey nurses on their work plans to inform possible remedies. METHODS: In March 2022, 9150 nurses with a Michigan license completed a survey on their plans to leave their current nursing position, reduce their hours, or pursue travel nursing. Another 1224 nurses who left their nursing position within the past 2 years also reported their reasons for departure. Logistic regression models with backward selection procedures estimated the effects of age, workplace concerns, and workplace factors on the intent to leave, hour reduction, pursuit of travel nursing (all within the next year), or departure from practice within the past 2 years. RESULTS: Among practicing nurses surveyed, 39% intended to leave their position in the next year, 28% planned to reduce their clinical hours, and 18% planned to pursue travel nursing. Top-ranked workplace concerns among nurses were adequate staffing, patient safety, and staff safety. The majority of practicing nurses (84%) met the threshold for emotional exhaustion. Consistent factors associated with adverse job outcomes include inadequate staffing and resource adequacy, exhaustion, unfavorable practice environments, and workplace violence events. Frequent use of mandatory overtime was associated with a higher likelihood of departure from the practice in the past 2 years (Odds Ratio 1.72, 95% CI 1.40-2.11). CONCLUSIONS: The factors associated with adverse job outcomes among nurses-intent to leave, reduced clinical hours, travel nursing, or recent departure-consistently align with issues that predated the pandemic. Few nurses cite COVID as the primary cause for their planned or actual departure. To maintain an adequate nursing workforce in the United States, health systems should enact urgent efforts to reduce overtime use, strengthen work environments, implement anti-violence protocols, and ensure adequate staffing to meet patient care needs.

Accelerating improvement: The Pediatric Acute Care Cardiology Collaborative data timeliness project.

BACKGROUND: The Pediatric Acute Care Cardiology Collaborative (PAC3) is a learning network focused on improving acute care cardiology patient outcomes. Data submission timeliness is a vulnerability for PAC3 and most clinical registries, directly affecting collaborative benchmarking, quality improvement (QI) and research projects. OBJECTIVE: PAC3 conducted a collaborative-wide QI project addressing data timeliness and efficiency. Data analysis of submitted cases from September 2019 to February 2020 revealed nine 'High Performer' centers who submitted cases within 67 days of hospital discharge (the limit for timeliness) >90% of the time and eight 'High Potential' sites who submitted timely cases <75% of the time. The primary aim was to increase case submission timeliness in 'High Potential' centers from 41% to 80% by December 2020. The secondary aim was to maintain timeliness in 'High Performer' sites. METHOD: During the intervention phase (March-December 2020), plan-do-study-act (PDSA) cycles included webinars, facilitated exploratory conversations, data review and development of a best practice guide ('Getting Started Toolkit'). On-boarded 'New Centers' starting in 2020 were also invited to test intervention effectiveness. Balancing measures included data collector job satisfaction and stress and resubmission rates. RESULTS: 'High Performer' and 'High Potential' centers submitted 11 358 cases from November 2019 to December 2020. Timely submission rates for 'High Potential' centers improved from 40.6% to 74.6% and were maintained at >90% for 'High Performer' centers. 'New Centers' averaged 92.6% timely case submissions during their first 6 months. Data collector job satisfaction and stress were not impacted, and the resubmission rates did not increase. CONCLUSION: PAC3's multicenter QI project increased data submission timeliness in a large pediatric subspecialty registry. The lessons learned and the Toolkit developed can be applied in other registries to improve data submission efficiency, with resultant improvement in benchmarking, QI, research, length of stay and outcomes.

Successful Reduction of Postoperative Chest Tube Duration and Length of Stay After Congenital Heart Surgery: A Multicenter Collaborative Improvement Project.

Background Congenital heart disease practices and outcomes vary significantly across centers, including postoperative chest tube (CT) management, which may impact postoperative length of stay (LOS). We used collaborative learning methods to determine whether centers could adapt and safely implement best practices for CT management, resulting in reduced postoperative CT duration and LOS. Methods and Results Nine pediatric heart centers partnered together through 2 learning networks. Patients undergoing 1 of 9 benchmark congenital heart operations were included. Baseline data were collected from June 2017 to June 2018, and intervention-phase data were collected from July 2018 to December 2019. Collaborative learning methods included review of best practices from a model center, regular data feedback, and quality improvement coaching. Center teams adapted CT removal practices (eg, timing, volume criteria) from the model center to their local resources, practices, and setting. Postoperative CT duration in hours and LOS in days were analyzed using statistical process control methodology. Overall, 2309 patients were included. Patient characteristics did not differ between the study and intervention phases. Statistical process control analysis showed an aggregate 15.6% decrease in geometric mean CT duration (72.6 hours at baseline to 61.3 hours during intervention) and a 9.8% reduction in geometric mean LOS (9.2 days at baseline to 8.3 days during intervention). Adverse events did not increase when comparing the baseline and intervention phases: CT replacement (1.8% versus 2.0%, P=0.56) and readmission for pleural effusion (0.4% versus 0.5%, P=0.29). Conclusions We successfully lowered postoperative CT duration and observed an associated reduction in LOS across 9 centers using collaborative learning methodology.

Center Variation in Chest Tube Duration and Length of Stay After Congenital Heart Surgery.

BACKGROUND: Nearly every child undergoing congenital heart surgery has chest tubes placed intraoperatively. Center variation in removal practices and impact on outcomes has not been well described. This study evaluated variation in chest tube management practices and outcomes across centers. METHODS: The study included patients undergoing any of 10 benchmark operations from June 2017 to May 2018 at participating Pediatric Acute Care Cardiology Collaborative (PAC3) and Pediatric Cardiac Critical Care Consortium (PC4) centers. Clinical data from PC4 centers were merged with chest tube data from PAC3 centers. Practices and outcomes were compared across centers in univariate and multivariable analysis. RESULTS: The cohort included 1029 patients (N = 9 centers). Median chest tube duration varied significantly across centers for 9 of 10 benchmark operations (all P ≤ .03), with a "model" center noted to have the shortest duration for 9 of 10 operations (range, 27.9% to 87.4% shorter duration vs other centers across operations). This effect persisted in multivariable analysis (P < .0001). The model center had higher volumes of chest tube output before removal (median, 8.5 mL/kg/24 h [model] vs 2.2 mL/kg/24 h [other centers]; P < .001], but it did not have higher rates of chest tube reinsertion (model center 1.3% vs 2.1%; P = .59) or readmission for pleural effusion (model center 4.4% vs 3.0%; P = .31), and had the shortest length of stay for 7 of 10 operations. CONCLUSIONS: This study suggests significant center variation in chest tube removal practices and associated outcomes after congenital heart surgery. Best practices used at the model center have informed the design of an ongoing collaborative learning project aimed at reducing chest tube duration and length of stay.

The Epidemiology of Herpes Simplex Virus Type 1 in Asia: Systematic Review, Meta-analyses, and Meta-regressions.

BACKGROUND: Herpes simplex virus type 1 (HSV-1) epidemiology in Asia was characterized by assessing seroprevalence levels and extent to which HSV-1 is isolated from clinically diagnosed genital ulcer disease (GUD) and genital herpes. METHODS: HSV-1 reports in Asia were systematically reviewed and synthesized, following PRISMA guidelines. Random-effects meta-analyses estimated pooled mean seroprevalence and proportion of HSV-1 detection in GUD and genital herpes. Random-effects meta-regressions identified predictors of seroprevalence and sources of between-study heterogeneity. RESULTS: Forty-nine relevant publications were identified. Fifty-four overall seroprevalence measures (182 stratified measures), and 8 and 24 proportions of HSV-1 detection in GUD and in genital herpes, respectively, were extracted. The pooled mean seroprevalence was 50.0% (n = 26; 95% confidence interval [CI], 41.3%-58.7%) for children and 76.5% (n = 151; 73.3%-79.6%) for adults. By age group, the pooled mean was lowest at 55.5% (n = 37; 95% CI, 47.5%-63.4%) in individuals aged <20 years, followed by 67.9% (n = 48; 62.4%-73.3%) in those aged 20-39 and 87.5% (n = 44; 83.4%-91.1%) in those aged ≥40 years. In meta-regression, age was the major predictor of seroprevalence. The mean proportion of HSV-1 detection was 5.6% (n = 8; 95% CI, 0.8%-13.6%) in GUD and 18.8% (n = 24; 12.0%-26.7%) in genital herpes. CONCLUSIONS: HSV-1 epidemiology is transitioning in Asia. HSV-1 is probably playing a significant role as a sexually transmitted infection, explaining one-fifth of genital herpes cases. There is a need for expanded seroprevalence monitoring and GUD/genital herpes etiological surveillance.

A germline-limited piggyBac transposase gene is required for precise excision in Tetrahymena genome rearrangement.

Developmentally programmed genome rearrangement accompanies differentiation of the silent germline micronucleus into the transcriptionally active somatic macronucleus in the ciliated protozoan Tetrahymena thermophila. Internal eliminated sequences (IES) are excised, followed by rejoining of MAC-destined sequences, while fragmentation occurs at conserved chromosome breakage sequences, generating macronuclear chromosomes. Some macronuclear chromosomes, referred to as non-maintained chromosomes (NMC), are lost soon after differentiation. Large NMC contain genes implicated in development-specific roles. One such gene encodes the domesticated piggyBac transposase TPB6, required for heterochromatin-dependent precise excision of IES residing within exons of functionally important genes. These conserved exonic IES determine alternative transcription products in the developing macronucleus; some even contain free-standing genes. Examples of precise loss of some exonic IES in the micronucleus and retention of others in the macronucleus of related species suggest an evolutionary analogy to introns. Our results reveal that germline-limited sequences can encode genes with specific expression patterns and development-related functions, which may be a recurring theme in eukaryotic organisms experiencing programmed genome rearrangement during germline to soma differentiation.
