Published: April 2021

Objective
Isolated facial injuries are less common among pediatric trauma patients. The literature has focused on, especially, fractures in facial injuries. There is a limited number of studies evaluating all facial injuries in childhood. The study aims to evaluate the clinical characteristics of maxillofacial injuries and to identify patients who require further intervention.

Methods
The data from pediatric patients with maxillofacial injury (<18 years) between January 2011 and December 2015 were collected. Demographic characteristics, trauma mechanisms, concomitant injuries, treatments, hospitalization, and follow-up results were recorded.

Results
The median age of the patients (N = 2926) was 5.0 years (2.0–10.0 years), and 63.1% were boys. Falls and motor vehicle accidents were the leading mechanism of injury. The most common injury types were lacerations (49.3%) and fractures (15.5%). One hundred thirty (0.4%) patients had concomitant injuries. Surgical treatment was performed in only 3.4% of the patients, and the mortality rate was 0.6%. Patients with concomitant injuries had more hospitalization rates, surgical treatment, and organ dysfunction. All patients who underwent cardiopulmonary resuscitation and resulted in mortality were in the concomitant injury group.

Conclusions
Isolated facial injuries are unlikely to be life-threatening, and basic interventions are sufficient in most of the maxillofacial injuries. The primary issue in maxillofacial injuries is to recognize and manage concomitant injuries that can lead to organ dysfunction and mortality.
Injuries Suggestive of Physical Abuse in Young Children With Subconjunctival Hemorrhages
Authors: Wolford Jennifer E. , Berger Rachel P. , Eichman Adelaide L. , Lindberg Daniel M. 
Published: April 2021

Objective
The aim of this study was to compare the demographic characteristics, clinical presentations, medical evaluation, and injuries identified in a cohort of children with and without subconjunctival hemorrhage who were evaluated by a child abuse specialist.

Methods
This was a case-control study that used data from the ExSTRA (Examining Siblings to Recognize Abuse) research network. Subjects with a subconjunctival hemorrhage(s) were designated as cases. Four controls matched for age and participating center were included for each case. Descriptive statistics were used to compare cases and controls.

Results
Fifty of the 2890 subjects in the parent study had a subconjunctival hemorrhage(s) and were designated as cases. The cases had a median (interquartile range) age of 5.0 months (2.0–23.6 months). Two hundred controls were matched to the cases. There was no difference in the demographics, clinical characteristics, medical evaluation, or rate of occult injuries identified in cases and controls. Almost one-quarter of children with subconjunctival hemorrhages had no other external sign of trauma but had the same rate of occult injuries as children with bruises.

Conclusions
These data suggest that subconjunctival hemorrhages are relatively rare among children undergoing evaluation by a child abuse specialist, but that they are often an indicator of occult injury. Even in the absence of other external signs of trauma, the presence of subconjunctival hemorrhages should prompt an age-appropriate evaluation for physical abuse.
Optimizing Critical Care Documentation in a Pediatric Emergency Department
Authors: Jain Shobhit , Shastri Nirav J. , Sharma Nikita , Conners Gregory P. 
Published: April 2021

Objective
Emergency department (ED) physicians frequently provide critical care (CC) but document inconsistently. Variability in documentation can result in underbilling and is inconsistent with financial stewardship. We used admissions to the intensive care unit (ICU) as a proxy for CC provision. At baseline, CC notes were correctly documented for 20% of eligible visits, with potential missed charges of $1.8 million per year.
Our objective was to increase CC note placement for eligible patients from 20% to 60% over 2 years. Additionally, we measured CC notes and the number of ICU admissions per 1000 ED visits, and change in facility fees.

Methods
We performed this project at a midwestern quaternary children's hospital with 2 EDs (combined volume 120,000 visits/year). We surveyed the ED physicians to inform our interventions. We used maintenance of certification points and financial incentives for quality improvement work to obtain buy-in. We used serial interventions with plan-do-study-act cycles: (1) CC note simplification, (2) education, (3) follow-up surveys, (4) additional location for CC note, and (5) timely reminders. We reviewed sample charts and used χ2 test and control charts for analysis.

Results
Critical care note placement for ICU admissions increased from 20% to 60% in 8 months, and further to greater than 75%. The CC notes increased from 4 to 16 per 1000 ED visits. Intensive care unit admissions increased but remained appropriate. The billed facility fee for CC increased by 263%.

Conclusions
This project resulted in significant and sustained improvements in CC note completion. We believe providing education, simplifying the documentation process, automating reminders, and incentivizing optimal documentation were vital to success.

Published: April 2021

ABSTRACT

Objective
In patients with heart failure with preserved ejection fraction (HFpEF), whether living alone could contribute to a poor prognosis remains unknown. We sought to investigate the association of living alone with clinical outcomes in patients with HFpEF.

Methods
Symptomatic patients with HFpEF with a follow-up of 3.3 years (data collected from August 2006 to June 2013) in the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist trial were classified as patients living alone and those living with others. The primary outcome was defined as a composite of cardiovascular death, aborted cardiac arrest, or HF hospitalization.

Results
A total of 3103 patients with HFpEF were included; 25.2% of them were living alone and were older, predominantly female, and less likely to be White and have more comorbidities compared with the other patients. After multivariate adjustment for confounders, living alone was associated with increased risks of HF hospitalization (hazard ratio [HR] = 1.29, 95% confidence interval [CI] = 1.03–1.61) and any hospitalization (HR = 1.26, 95% CI = 1.12–1.42). A significantly increased risk of any hospitalization (HR = 1.16, 95% CI = 1.01–1.34) was also observed in the Americas-based sample. In addition, each year increase in age, female sex, non-White race, New York Heart Association functional classes III and IV, dyslipidemia, and chronic obstructive pulmonary disease were independently associated with living alone.

Conclusions
We assessed the effect of living arrangement status on clinical outcomes in patients with HFpEF and suggested that living alone was associated with an independent increase in any hospitalization.

Using Novel Approaches to Evaluate Behavioral Interventions: Overlooked Significant HIV Prevention Effects in the HPTN 015 Project EXPLORE
Authors: Pitpitan Eileen V. , MacKinnon David P. , Eaton Lisa A. , Smith Laramie R. , Wagman Jennifer , Patterson Thomas L. 
Published: April 2021

Background:
Mediated and moderated processes that lead to intervention efficacy may underlie results of trials ruled as nonefficacious. The overall purpose of this study was to examine such processes to explain the findings of one of the largest, rigorously conducted behavioral intervention randomized controlled trials, EXPLORE.

Methods:
Four thousand two hundred ninety-five HIV-negative men who have sex with men (MSM) in the United States were randomized in a 2-armed trial. Participants completed follow-up and an HIV test every 6 months up to 48 months. We used multiple and causal mediation analyses to test 5 mediators, including safer sex self-efficacy and condomless receptive anal sex with HIV-positive or status-unknown partners on our primary outcome (HIV seroconversion). We also examined whether intervention effects on the mediators would be moderated by robust correlates of HIV among MSM, including stimulant use.

Results:
There were significant effects of the intervention on all hypothesized mediators. Stimulant use moderated the effect on condomless receptive anal sex In stratified multiple mediation models, we found that among MSM with low stimulant use, the intervention significantly prevented HIV by reducing condomless receptive anal sex with HIV-positive or status-unknown partners. Among MSM with higher stimulant use, there were no indirect effects of the intervention on HIV through any of the hypothesized mediators.

Conclusion:
The results suggest that the null effect found in the original EXPLORE trial might have occurred as a function of previously unexplored mediated and moderated processes. This study illustrates the value of testing mediated and moderated pathways in randomized trials, even in trials ruled out as nonefficacious.
Accelerometer-Based Physical Activity Patterns and Associations With Outcomes Among Individuals With Osteoarthritis

Published: April 2021

Background
This study examined patterns of physical activity and associations with pain, function, fatigue, and sleep disturbance among individuals with knee or hip osteoarthritis.

Methods
Participants (n = 54) were enrolled in a telephone-based physical activity coaching intervention trial; all data were collected at baseline. Self-reported measures of pain and function (WOMAC [Western Ontario and McMaster Universities Osteoarthritis Index] subscales), fatigue (10-point numeric rating scale), and PROMIS (Patient-Reported Outcomes Information System) Sleep Disturbance were collected via telephone. Accelerometers were mailed to participants and were worn for at least 3 days. Proportion of time participants spent in sedentary behavior during the morning (from wake until 12:00 pm), afternoon (12:00 pm until 5:59 pm) and evening (6:00 pm until sleep) each day was averaged across all days of wear. Pearson correlations assessed associations between activity and self-reported measures.

Results
Participants spent a large proportion of time in sedentary behavior: 65.6% of mornings, 70.0% of afternoons, and 76.6% of evenings. Associations between proportion of time spent in sedentary behavior and reported outcomes were generally strongest in the afternoon, strongest for WOMAC function, and lowest for PROMIS Sleep Disturbance. In the evening hours, sedentary time was most strongly associated with fatigue.

Conclusions
Overall, findings stress the importance of reducing sedentary behavior among adults with osteoarthritis and suggest behavioral interventions may be strengthened by considering patients’ within-day variation in symptoms and activity.
COVID-19 and Inpatient Rehabilitation Nursing Care: Lessons Learned and Implications for the Future
Authors: Camicia Michelle E. , Cournan Michele C. , Rye Jill 
Published: April 2021

Abstract
The SARS-CoV-2 coronavirus (COVID-19) pandemic is impacting post-acute inpatient rehabilitation nursing practice from preadmission assessment to inpatient care delivery and transition planning. Patients with disability following COVID-19 require interventions to address respiratory, cardiovascular, neurological, musculoskeletal, and psychosocial issues. The pandemic has resulted in changes to program structures and how inpatient rehabilitation facilities approach family caregiver engagement amidst visitation restrictions. Technology solutions can be utilized to reduce the patient and their family's feelings of isolation and support caregiver preparation for discharge. Nurse leaders are essential in supporting staff during this crisis through authentic presence and providing resources and training. Rehabilitation nurses are key in helping patients and families manage rehabilitation and the aftermath of COVID-19 to restore optimal functioning. In this clinical consultation, we synthesize insights learned from the COVID-19 responses at three inpatient rehabilitation facilities. We describe the impact of rehabilitation nursing interventions to improve outcomes for patients with COVID-19 and their caregivers.

Published: April 2021

BACKGROUND
Low-molecular-weight heparin (LMWH) is widely used for venous thromboembolism chemoprophylaxis following injury. However, unfractionated heparin (UFH) is a less expensive option. We compared LMWH and UFH for prevention of posttraumatic deep venous thrombosis (DVT) and pulmonary embolism (PE).

METHODS
Trauma patients 15 years or older with at least one administration of venous thromboembolism chemoprophylaxis at two level I trauma centers with similar DVT-screening protocols were identified. Center 1 administered UFH every 8 hours for chemoprophylaxis, and center 2 used twice-daily antifactor Xa-adjusted LMWH. Clinical characteristics and primary chemoprophylaxis agent were evaluated in a two-level logistic regression model. Primary outcome was incidence of DVT and PE.

RESULTS
There were 3,654 patients: 1,155 at center 1 and 2,499 at center 2. The unadjusted DVT rate at center 1 was lower than at center 2 (3.5% vs. 5.0%; p = 0.04); PE rates did not significantly differ (0.4% vs. 0.6%; p = 0.64). Patients at center 2 were older (mean, 50.3 vs. 47.3 years; p < 0.001) and had higher Injury Severity Scores (median, 10 vs. 9; p < 0.001), longer stays in the hospital (mean, 9.4 vs. 7.0 days; p < 0.001) and intensive care unit (mean, 3.0 vs. 1.3 days; p < 0.001), and a higher mortality rate (1.6% vs. 0.6%, p = 0.02) than patients at center 1. Center 1’s patients received their first dose of chemoprophylaxis earlier than patients at center 2 (median, 1.0 vs. 1.7 days; p < 0.001). After risk adjustment and accounting for center effects, primary chemoprophylaxis agent was not associated with risk of DVT (odds ratio, 1.01; 95% confidence interval, 0.69–1.48; p = 0.949). Cost calculations showed that UFH was less expensive than LMWH.

CONCLUSION
Primary utilization of UFH is not inferior to LMWH for posttraumatic DVT chemoprophylaxis and rates of PE are similar. Given that UFH is lower in cost, the choice of this chemoprophylaxis agent may have major economic implications.

Designing a Liver Transplant Patient and Family Decision Support Tool for Organ Offer Decisions
Authors: Schaffhausen Cory R. , Bruin Marilyn J. , Chu Sauman , McKinney Warren T. , Lake Jack R. , Chinnakotla Srinath , Israni Ajay K. 
Published: April 2021

Background.
For liver transplant candidates on the waiting list, deciding to accept a donor organ with known or potential risk factors can be stressful and can lead to declined offers. Current education for patients and family often takes place during transplant evaluations and can be overwhelming and result in low retention and poor understanding of donor quality.

Methods.
In the first phase, we sought to understand provider experiences when counseling patients about donor risks and donor offers. We conducted interviews and focus groups with liver transplant providers at 1 local center and at a national clinician conference. Twenty providers participated: 15 hepatologists and 5 surgeons. The provider feedback was used to create an initial outline of content that is consistent with decision support frameworks. In a second phase, graphic design collaborators created mockups of a patient-friendly tool. We reviewed mockups with 4 transplant coordinators and 9 liver transplant candidates for feedback on clarity and utility to prepare for an organ offer. Patient responses allowed a comparison of perceived readiness to receive an offer call before and after viewing mockups.

Results.
We identified themes relating to the offer process, repetition and timing of education, and standardization and tailoring of content. The results indicated a gap in available education after the evaluation session, and information specific to offer decisions is needed. Patient feedback emphasized the need to review the offer process before a real offer.

Conclusions.
Patients and providers responded favorably to a patient tool addressing existing gaps in education while waiting for a donor offer. Additional patient, family, and provider feedback will guide the development of an interactive tool to prepare patients and families for an offer decision.
Effective vaccine allocation strategies, balancing economy with infection control against COVID-19 in Japan

Published: April 2021

AbstractDue to COVID-19, many countries including Japan have implemented a suspension of economic activities for infection control. It has contributed to reduce the transmission of COVID-19 but caused severe economic losses. Today, several promising vaccines have been developed and are already being distributed in some countries. Therefore, we evaluated various vaccine and intensive countermeasure strategies with constraint of economic loss using SEIR model to obtain knowledge of how to balance economy with infection control in Japan. Our main result is that the vaccination strategy that prioritizes younger generation outperformed the other strategies in terms of deaths. On the other hand, when we focused on strategies that prioritize older generation, as Japan has decided to do, the optimal vaccination strategy was determined by the basic reproduction number and acceptable economic loss. The strategy vaccinating the young next to the old age group was the best when acceptable economic loss was high, or the basic reproduction number was low. Alternatively, the strategy vaccinating the middle next to the old age group was superior to the others with a moderate acceptable economic loss and the high basic reproduction number setting.
Have news reports on suicide and attempted suicide during the COVID-19 pandemic adhered to guidance on safer reporting? A UK-wide content analysis study

Published: April 2021

AbstractAssociations between sensational news coverage of suicide and subsequent increases in suicidal behaviour in the general population have been well documented. Amidst growing concern over the impact of the COVID-19 pandemic on suicide rates, it is especially important that news coverage of suicidal behaviour adheres to recommended standards for the responsible reporting of suicide. Using a set of dimensions based on international media guidelines, we analysed the quality and content of all UK news reports of possible COVID-19 related suicides and suicide attempts in the first four months of the pandemic (N=285 reports of 78 individual incidents published in print and online newspapers between 16th March and 12th July 2020). The majority of news reports made an explicit link between suicidal behaviour and the COVID-19 pandemic in the headline (187/285, 65.5%), and portrayed this association as strong and direct (n=196/272, 72.1%), mostly based on statements by family, friends or acquaintances of the deceased (171/285, 60%). The impact of the pandemic on suicidal behaviour was most often attributed to feelings of isolation (78/285, 27.4%), poor mental health (42, 14.7%) and sense of entrapment (41, 14.4%) as a result of government-imposed restrictions. Although rarely of poor overall quality, reporting was biased towards young people, frontline staff and relatively unusual suicides (including those involving a celebrity, murder-suicide and violent methods) Also, to varying degrees, reports failed to meet recommended standards; for example, 41.1% (117/285) did not signpost readers to sources of support, a quarter (69, 24.2%) included examples of sensational language and a third provided over-simplistic explanations for the suicidal behavior (93, 32.6%). While news reporting has improved compared to earlier coverage of suicide in the UK, it is essential that careful attention is paid to the quality and content of reports, especially as longer-term consequences of the COVID-19 pandemic develop.
When can we stop wearing masks? Agent-based modeling to identify when vaccine coverage makes nonpharmaceutical interventions for reducing SARS-CoV-2 infections redundant in indoor gatherings
Authors: Farthing Trevor S. , Lanzas Cristina 
Published: April 2021

AbstractAs vaccination efforts to combat the COVID-19 pandemic are ramping up worldwide, there are rising concerns that individuals will begin to eschew nonpharmaceutical interventions for preventing SARS-CoV-2 transmission and attempt to return to pre-pandemic normalcy before vaccine coverage levels effectively mitigate transmission risk. In the U.S.A., some governing bodies have already weakened or repealed guidelines for nonpharmaceutical intervention use, despite a recent spike in national COVID-19 cases and majority population of unvaccinated individuals. Recent modeling suggests that repealing nonpharmaceutical intervention guidelines too early into vaccine rollouts will lead to localized increases in COVID-19 cases, but the magnitude of nonpharmaceutical intervention effects on individual-level SARS-CoV-2 infection risk in fully- and partially-vaccinated populations is unclear. We use a previously-published agent-based model to simulate SARS-CoV-2 transmission in indoor gatherings of varying durations, population densities, and vaccination coverage levels. By simulating nonpharmaceutical interventions in some gatherings but not others, we were able to quantify the difference in SARS-CoV-2 infection risk when nonpharmaceutical interventions were used, relative to scenarios with no nonpharmaceutical interventions. We found that nonpharmaceutical interventions will often reduce secondary attack rates, especially during brief interactions, and therefore there is no definitive vaccination coverage level that makes nonpharmaceutical interventions completely redundant. However, the reduction effect on absolute SARS-CoV-2 infection risk conferred by nonpharmaceutical interventions is likely proportional to COVID-19 prevalence. Therefore, if COVID-19 prevalence decreases in the future, nonpharmaceutical interventions will likely still confer protective effects but potential benefits may be small enough to remain within “effectively negligible” risk thresholds.
