Early Emergency Medicine Milestone Assessment for Predicting First-Year Resident Performance.

Introduction: The Accreditation Council for Graduate Medical Education (ACGME) requires emergency medicine (EM) residency training programs to monitor residents' progress using standardized milestones. The first assessment of PGY 1 resident milestones occurs midway through the first year and could miss initial deficiencies. Early assessment of PGY 1 EM resident milestones has potential to identify at-risk residents prior to standard midyear evaluations. We developed an orientation syllabus for PGY 1 residents followed by a milestone assessment. Assessment scores helped predict future milestone scores and American Board of Emergency Medicine (ABEM) In-Training Examination (ITE) scores for PGY 1 residents. Methods: From 2013 to 2020, we developed and implemented Milestone Evaluation Day (MED), a simulation-based day and written exam assessing PGY 1 EM residents during their first month on the 23 ACGME 1.0 milestones. MED stations included a history and physical with verbal presentation, patient simulation, vascular access, wound management, and airway management. MED, Clinical Competency Committee-generated (CCC-generated) milestone, and ABEM ITE scores were averaged and compared utilizing Pearson's correlation coefficient. Results: Of 112 PGY 1 EM residents, 110 (98%) were analyzed over an 8-year period. We observed a moderate positive correlation of MED and CCC-generated milestone scores (r = .34, p < .001). There was a nonstatistically significant weak positive correlation of MED and ABEM ITE scores (r = .13, p = .17). Discussion: An early assessment of EM milestones in the PGY 1 year can assist in the prediction of CCC-generated milestone scores for PGY 1 residents.

Association of Epigenetic Age and Everyday Discrimination With Longitudinal Trajectories of Chronic Health Conditions in Older Adults.

We investigated the strength of the association between baseline epigenetic age, everyday discrimination, and trajectories of chronic health conditions (CHCs) across 3 study waves, among adults 50 years of age and older. We used 2016-2020 data from the Health and Retirement Study (HRS). Data for the PhenoAge and DNAm GrimAge second-generation epigenetic clocks were from the 2016 HRS Venous Blood Study. CHC trajectories were constructed using latent class growth curve models. Multinomial logistic regression models assessed the strength of the association between accelerated epigenetic age, everyday discrimination, and the newly constructed CHC trajectories for participants with complete data (n = 2 893). In the fully adjusted model, accelerated PhenoAge (relative risk ratios [RRR] = 2.53, 95% confidence interval [95% CI] = 1.81, 3.55) and DNAm GrimAge (RRR = 2.79, 95% CI = 1.95, 4.00) were associated with classification into the high CHC trajectory class. Racial disparities were evident, with increased risk of classification into the high trajectory class for Black (PhenoAge: RRR = 1.69, 95% CI = 1.07, 2.68) and reduced risk for Hispanic (PhenoAge: RRR = 0.32, 95% CI = 0.16, 0.64; DNAm GrimAge: RRR = 0.34, 95% CI = 0.17, 0.68), relative to White participants. Everyday discrimination was associated with classification into the medium-high (RRR = 1.28, 95% CI = 1.00, 1.64) and high (RRR = 1.52, 95% CI = 1.07, 2.16) trajectory classes in models assessing DNAm GrimAge. More research is needed to better understand the longitudinal health outcomes of accelerated aging and adverse social exposures. Such research may provide insights into vulnerable adults who may need varied welfare supports earlier than the mandated chronological age for access to federal and state resources.

Emergency department use of an electronic differential diagnosis generator in the evaluation of critically ill patients.

BACKGROUND: Accurate diagnosis is an essential component of managing critically ill emergency department (ED) patients. Electronic diagnosis generators (EDGs) are software tools which assist clinicians in their diagnosis generation; however, they have not been evaluated for use for critical ED patients. We aimed to evaluate the use of an EDG for this population to determine its impact on diagnosis generation and diagnostic testing. METHODS: We performed an observational study on usage of an EDG in the high-acuity area of a tertiary care ED. The EDG was used by residents evaluating each patient in the area. The resident used the EDG when the case was felt to have diagnostic uncertainty and completed a data collection tool. Data were summarized by frequencies. Chi-squared or Fisher's exact tests were used to assess the association of added value of the EDG for diagnosis generation and diagnostic testing. RESULTS: Over the 8-month study period, the EDG was utilized to evaluate 98 critical ED patients, of whom 60% were female, 7% were pediatric, and 46% were elderly. It was used most commonly for gastroenterological, infectious disease/immunologic, metabolic/renal, and neuropsychiatric presentations, and was least used for trauma presentations. Use of the EDG led to a diagnosis not initially considered in 47% of cases and led to additional diagnostic testing in 4% of cases. CONCLUSION: EDGs have some potential to improve diagnosis in critical EM patients by expanding the differential diagnosis and, to a lesser extent, altering diagnostic testing.

Risk Factors for Coated Midline Catheter-Related Thrombosis: A Secondary Analysis of Existing Trial Data.

Midline catheter-related thrombosis (MCRT) is a high-stakes complication. The authors aimed to explore risk factors for the development of symptomatic MCRT, including patient, procedure, catheter, and vein characteristics. This study performed an analysis of existing trial data that compared MCRT in 2 MCs with differing antithrombotic properties. Cox regression was used for univariable and multivariable analyses to evaluate the primary outcome of MCRT. Among 191 patients in this analysis, the average age was 60.2 years (standard deviation = 16.7 years), and 59.7% were female (114/191). Clinical indications for MC placement included antibiotics (60.7%), difficult venous access (32.5%), or both (6.8%). Body temperature ≥38°C (adjusted hazard ratio [aHR] = 6.26; 95% CI, 1.24-20.29; P = .03), catheter-to-vein ratio >0.40 (aHR = 2.65; 95% CI, 0.99-6.74; P = .05), and MC distance from antecubital fossa >7.0 cm (aHR = 2.82; 95% CI, 1.10-7.90; P = .03), were each significantly associated with the higher risk of the occurrence of symptomatic MCRT. This study found that catheter-to-vein ratio >0.40, distance from the antecubital fossa >7 cm, and body temperature ≥38°C were each associated with higher risk of MCRT. Current practices should be modified to include a minimum vein size to avoid MC insertions that occupy >40% of a given vein. Further research is needed to explain the impact of the catheter tip position and fever in relation to MCRT.

Effect of Instrumented Spine Surgery on Length of Stay.

INTRODUCTION: Total joint arthroplasty studies have identified that surgeries that take place later in the week have a longer length of stay compared with those earlier in the week. This has not been demonstrated in studies focused on anterior cervical diskectomy and fusions or minimally invasive lumbar laminectomies. All-inclusive instrumented spine surgeries, however, have not been analyzed. The purpose of this study was to determine whether day of surgery affects length of stay and whether there are predictive patient characteristics that affect length of stay in instrumented spine surgery. METHODS: All instrumented spine surgeries in 2019 at a single academic tertiary center were retrospectively reviewed. Patients were categorized for surgical day and discharge disposition to home or a rehabilitation facility. Differences by patient characteristics in length of stay and discharge disposition were compared using Kruskal-Wallis and chi square tests along with multiple comparisons. RESULTS: Seven hundred six patients were included in the analysis. Excluding Saturday, there were no differences in length of stay based on the day of surgery. Age older than 75 years, female, American Society of Anesthesiology (ASA) classification of 3 or 4, and an increased Charlson Comorbidity Index were all associated with a notable increase in length of stay. While most of the patients were discharged home, discharge to a rehabilitation facility stayed, on average, 4.7 days longer (6.8 days compared with 2.1 days, on average) and were associated with an age older than 66 years old, an ASA classification of 3 or 4, and a Charlson Comorbidity Index of 1 to 3. CONCLUSIONS: Day of surgery does not affect length of stay in instrumented spine surgeries. Discharge to a rehabilitation facility, however, did increase the length of stay as did age older than 75 years, higher ASA classification, and increased Charlson Comorbidity Index classification.

A Comparison of Prehospital Pediatric Analgesic Use of Ketamine and Opioids.

OBJECTIVE/INTRODUCTION: Ketamine is an opioid-alternative used for analgesia in the prehospital setting. There are knowledge gaps regarding its use during emergency medical services (EMS) encounters for pediatric patients. Our objective was to compare pain reduction, adverse events, and prehospital deaths between ketamine and opioids when used for analgesia administered by any route among pediatric patients. METHODS: This was a retrospective review of 9-1-1 EMS records of injured pediatric patients (≤17 years of age) who received ketamine or opioids for analgesia using the ESO Data Collaborative (calendar years 2019-2020). We excluded interfacility transfers, patients receiving both medications, those with EMS clinician impressions indicating behavioral disorders, and those who received medication to facilitate advanced airway placement. EMS narrative review was performed to confirm ketamine use was for analgesia and to identify any unplanned airway placements. We assessed pain score reduction (0-10 ordinal scale) and clinician-documented patient response (improved, unchanged, worsened, unknown). Adverse events were defined as change in vital signs (GCS, SBP, RR, SpO2), bag valve mask ventilation alone, or death. Descriptive statistics were calculated to compare outcomes between groups. RESULTS: Overall, 9,223 patients were included, 190 (2.1%) received ketamine and 9,033 (97.9%) received opioids. Mean age in years was 12.8 [SD 4.0] for ketamine and 12.7 [SD 4.0] for opioids. Patients in both groups experienced pain reduction, and more patients receiving ketamine had EMS clinician reported improvement (93.2% vs. 87.9%, p = 0.03). Ketamine was associated with a greater average reduction in pain score than opioids (mean difference: -4.4 [SD 3.5], and -3.1 [SD 2.8], p < 0.001). Adverse events were rare with few patients receiving ventilatory support following the use of ketamine or opioids, (0, [SD 0.0%] vs. 6 [SD 0.1%], p = 1). There were no unplanned airway placements or prehospital deaths identified. CONCLUSION: We identified similar high rates of pain reduction and rare adverse events among pediatric patients who received ketamine or opioids. A greater pain reduction was noted among patients administered ketamine. Intubation as a result of medication administration did not occur and need for ventilatory assistance was rare.

Cost effectiveness of ultrasound-guided long peripheral catheters in difficult vascular access patients.

OBJECTIVE: Peripheral intravenous catheter (PIVC) placement is a routinely performed invasive procedure in hospital settings with an unacceptably high failure rate that can result in significant costs. This investigation aimed to determine the cost-effectiveness of using long peripheral catheters (LPC) versus standard short peripheral catheters (SPC) in the difficult vascular access (DVA) population. METHODS: A secondary analysis was performed of a randomized control trial that compared a 20-gauge 4.78 cm SPC to a 20-gauge 6.35 cm SPC for the endpoint of survival. This study assessed cost-effectiveness of the comparative interventions. Costs associated with increased hospitalization length of stay due to PIVC failure, including labor, materials, equipment, and treatment delays were estimated by utilizing healthcare resource utilization data. Cost-effectiveness of the LPC was analyzed through the incremental cost-effectiveness ratio, the cost-effectiveness acceptability curve, and the incremental net benefit. A sensitivity analysis was conducted to evaluate the robustness of the results during the time interval of PIVC insertion. RESULTS: Among the 257 patients, the average total cost for therapy was lower in the LPC group compared to the SPC group ($400 vs $521; mean difference -$121, 95% bootstrapped CI -$461 to $225). A marginally significant absolute difference of complication averted was found for LPC versus SPC (10.8%, p = 0.07). The estimated incremental cost-effectiveness ratio (ICER) for LPC as compared with SPC was -$1123 (95% bootstrapped CI -$8652 to $5964) per complication averted. In a willingness to pay (WTP) analysis, as WTP = $0, the incremental net benefit (INB) $121 was positive, indicating LPC was less costly. Analysis of PIVCs that survived ⩽48 h (n = 134) demonstrated a lower average total cost for therapy among the LPC group ($418 vs $531; mean difference -$113, 95% bootstrapped CI -$507 to $282). Forty-seven of 66 (71.2%) LPCs did not experience a complication, compared with 37 of 68 (54.4%) SPCs, resulting in a significant absolute difference of complication adverted of 16.8% (p = 0.04). In addition, with a positive slope, the INB $113 was positive as WTP = $0, indicating LPC was estimated to be cost-effective. CONCLUSIONS: When using ultrasound guidance for vascular access, LPCs are potentially a cost-effective strategy for reducing PIVC complications in DVA patients compared to SPCs. Given this finding, ultrasound-guided LPCs should be routinely considered as first-line among the DVA population in order to improve their overall care and wellbeing.

A Propensity-Matched Cohort Assessing Impact of a Neutralizing Monoclonal Antibody in Mild-to-Moderate Coronavirus Disease 2019.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoaV-2) is responsible for the coronavirus disease 2019 (COVID-19) pandemic. In randomized clinical trials, patients who were treated with the anti-spike monoclonal antibody bamlanivimab had fewer COVID-19-related hospitalizations or emergency department (ED) visits than the control group. Methods: A retrospective cohort was assembled across a multisite healthcare system between November 20, 2020 and March 31, 2021. Ambulatory COVID-19 patients treated with bamlanivimab (n = 209) were propensity score matched without replacement (1:1) to a pool of 1024 eligible control patients who received similar care without bamlanivimab. The primary endpoint was all-cause mortality or admission at 30 days. Secondary endpoints included hospitalization, critical care admission, oxygenation requirements, and infusion-related reactions. Propensity score matching (PSM) analysis was used to assess the effect of bamlanivimab infusion on the composite endpoint and secondary endpoints. Results: A total of n = 209 matched patients were included in each arm of the study. The absolute standardized difference (stddiff) was calculated and indicated a balance between the groups. Almost all variables had a stddiff of less than 0.10, except for respiratory rate (RR) (stddiff = -0.11). For the primary composite endpoint of the matched cohort, 10.1% (n = 21) of patients in the intervention group were hospitalized or deceased within 30-day postbamlanivimab infusion versus 27.8% (n = 58) in the control group (adjusted odds ratio [aOR]: 0.29, 95% confidence interval [CI]: 0.17 to 0.51, P < .001). Conclusion: Patients with ambulatory COVID-19 who received bamlanivimab in the outpatient setting had a statistically significant reduction on the odds of admission postinfusion. Despite bamlanivimab's lack of efficacy on newer SARS-CoV-2 variants, this study demonstrates that neutralizing monoclonal antibodies can be effective against specific variants. If variant identification becomes a more accessible tool in outpatient centers or EDs, more targeted therapeutic options may be considered.

Prehospital Use of Ketamine versus Benzodiazepines for Sedation among Pediatric Patients with Behavioral Emergencies.

INTRODUCTION: Ketamine is an emerging alternative sedation agent for prehospital management of agitation, yet research is limited regarding its use for children. Our objective was to compare the effectiveness and safety of ketamine and benzodiazepines when used for emergent prehospital sedation of pediatric patients with behavioral emergencies. METHODS: We performed a retrospective review of 9-1-1 EMS records from the 2019-2020 ESO Data Collaborative research datasets. We included patients ≤18 years of age who received ketamine or benzodiazepines for EMS primary and secondary impressions indicating behavioral conditions. We excluded patients with first Glasgow Coma Scale (GCS) scores ≤8, those receiving ketamine or benzodiazepines prior to EMS arrival, those receiving both ketamine and benzodiazepines, and interfacility transfers. Effectiveness outcomes included general clinician assessment of improvement, decrease in GCS, and administration of a subsequent sedative. Safety outcomes included mortality; advanced airway placement; ventilatory assistance without advanced airway placement; or marked sedation (GCS ≤8). Chi-square and t-tests were used to compare the ketamine and benzodiazepines groups. RESULTS: Of 57,970 pediatric patients with behavioral complaints and GCS scores >8, 1,539 received ketamine (13.3%, n = 205) or a benzodiazepine (86.7%, n = 1,334). Most patients were ≥12 years old (89.2%, n = 1,372), predominantly Caucasian (48.3%, n = 744), and were equally distributed by sex (49.7% male, n = 765). First treatment with ketamine was associated with a greater likelihood of improvement (88.8% vs 70.5%, p < 0.001) and a greater average GCS reduction compared to treatment with benzodiazepines (-2.5 [SD:4.0] vs -0.3 [SD:1.7], p < 0.001). Fewer patients who received ketamine received subsequent medication compared to those who received benzodiazepines (12.2% vs 27.0%, p < 0.001). Marked sedation was more frequent with ketamine than benzodiazepines (28.8% vs 2.9%, p < 0.001). Provision of ventilatory support (1.5% vs 0.5%, p = 0.14) and advanced airway placement (1.0% vs 0.2%, p = 0.09) were similar between ketamine and benzodiazepine groups. No prehospital deaths were reported. CONCLUSION: In this pediatric cohort, prehospital sedation with ketamine was associated with greater patient improvement, less subsequent sedative administration, and greater sedation compared to benzodiazepines. Though we identified low rates of adverse events in both groups, ketamine was associated with more instances of marked sedation, which bears further study.

Prehospital Ketamine Use in Pediatrics.

Introduction: Information regarding prehospital ketamine use in the pediatric population is limited as existing literature focuses primarily on critical care and air transport. Our objective was to describe patient characteristics among pediatric EMS patients who received ketamine. Secondarily, we assessed effectiveness, deviation from recommended dosing, and adverse outcomes of pediatric EMS patients who received ketamine.Methods: We conducted a retrospective data review of records from the ESO Data Collaborative for all 9-1-1 transports of pediatric patients (≤ 18 years of age) who received ketamine from 2019-2020. We categorized EMS primary impressions as a proxy for medication indication. We defined effectiveness as paramedic-identified clinical improvement, and pain relief as decrease in pain score ≥2 points between initial and final recording. Descriptive statistics were used to summarize clinical characteristics. Non-parametric Wilcoxon signed-rank test was used to assess change in pain score.Results: Out of 422,968 ground-ambulance pediatric patients, 1,291 received ketamine. They were predominately male (842, 65.2%), teenagers (median age 16, IQR: 13-17), Caucasian (810, 62.7%), and from urban areas (1,041, 80.6%). The most common EMS impressions were related to injuries (810, 62.7%) and behavior disorders (281, 21.8%). Only 980/1,291 (75.9%) had weights and identifiable routes recorded. Most patients (960, 74.4%) received single doses of ketamine, with EMS clinicians reporting improvement in 855 (89.1%) of 960 patients. Among non-behavioral emergency patients, 727/1,010 (72.0%) had pain scores recorded. Pain scores decreased significantly from a median of 8 (IQR: 4-10) to 2 (IQR: 0-6) (p < 0.001) with 59% (429) of 727 patients reporting pain score reductions of 2 or more points. Desaturation (<90% SpO2) events were noted to be minimal (1.8%). A small number (28, 2.2%) received positive pressure ventilation without advanced airway placement. No prehospital deaths were documented.Conclusion: In this large review of pediatric prehospital ketamine use, ketamine was primarily used for analgesia, but was frequently used for other indications. Most patients were observed to improve after ketamine use, with most injured patients reporting decreases in pain scores. We observed few significant adverse events related to ketamine use in this population.

Short peripheral intravenous catheter securement with cyanoacrylate glue compared to conventional dressing: A randomized controlled trial.

BACKGROUND: Short peripheral intravenous catheters (PIVCs) fail prior to completion of therapy in up to 63% of hospitalizations. This unacceptably high rate of failure has become the norm for the most common invasive procedure in all of medicine. Securement strategies may improve PIVC survival. METHODS: We conducted a prospective, single-site, parallel, two-arm randomized controlled investigation with a primary outcome of catheter failure comparing securement with standard semi-permeable dressing and clear tape (SPD) to standard semipermeable dressing and clear tape with cyanoacrylate glue (SPD + CG). Adult emergency department patients with a short PIVC and anticipated hospital duration ⩾ 48 h were enrolled and followed until IV failure or completion of therapy for up to 7 days. Secondary outcomes included complications and cost comparisons between groups. Primary outcome was assessed by intention to treat and per protocol analyses. FINDINGS: 350 patients were enrolled between November 2019 and October 2020. PIVC survival for SPD + CG was similar to SPD group with the absolute risk difference of IV failure in the intention-to-treat (-5.8%, p = 0.065) population and improved in the per protocol (-8.1%, p = 0.04) population, respectively. Kaplan-Meier survival analysis indicated there was a significant benefit of the SPD + CG at greater than 2 days of hospitalization (p = 0.04). Prior to 48 h, there was no survival enhancement to either group (p = 0.98) in the intention to treat population. In a multivariable analysis with piecewise Cox regression, when the IV was functional greater than 48 h, the risk of IV failure in the SPD + CG was 43% less than the SPD group (adjusted hazard ratio [HR] 0.57, 95% confidence interval [CI] 0.34 to 0.97; p = 0.04). Cumulative cost related to IV during hospitalization was similar between groups with a lower incremental rescue cost in the SPD + CG group. INTERPRETATION: SPD combined with cyanoacrylate glue provides similar benefit to patients compared to SPD alone and potentially improves short PIVC survival when the IV was inserted >48 h. As this strategy is cost neutral, it could be considered in admitted patients, particularly those with longer anticipated hospital durations.

The Effect of Resuscitation Residents on the Duration of Pre-induction of Targeted Temperature Management in Out-of-Hospital Cardiac Arrest.

Background The Resuscitation Rotation is a novel second-year emergency medicine rotation focusing on the highest acuity patients, including out-of-hospital cardiac arrest (OHCA). The resuscitation resident (RR) functions as an extra physician during resuscitation and post return of spontaneous circulation (ROSC). The objective of this study is to examine if the presence of a RR decreases the pre-induction interval of targeted temperature management (TTM) for patients following OHCA. Methods A retrospective study was conducted at a tertiary care level 1 trauma center with an annual ED census of 127,323 visits in 2019. We retrospectively reviewed consecutive OHCA patients from September 1, 2014, to July 20, 2020, who underwent TTM. Patients were identified as cases with or without a RR. Clinical characteristics were summarized by the status of RR involvement and compared by using t-test and χ2 test for continuous and categorical variables, respectively. All tests with p < 0.05 were considered to indicate statistical significance. Results Our study population identified 198 adult OHCA patients that underwent TTM from 2014-2020. There were exclusions for missing TTM start time and for missing patient characteristics leaving 176 for final analysis, of which 55 (33.3%) had RR involvement. The mean time (hours) to TTM initiation (ie, the pre-induction phase) for patients involving the RR versus those without was not statistically significant (3.11 vs 3.34, p=0.39). Linear regression analysis indicates that the adjusted effect of RR involvement was not associated with the mean hours of pre-induction (p=0.47). Conclusion There is no statistically significant association of a RR on the duration of the pre-induction phase. Limitations include that both arms had prolonged pre-induction phases. This may represent a non-optimized TTM protocol. Future work will aim to use the RR to improve our pre-induction phase.

Soy isoflavones decrease fibroglandular breast tissue measured by magnetic resonance imaging in premenopausal women: A 2-year randomized double-blind placebo controlled clinical trial.

BACKGROUND & AIMS: Populations consuming soy have reduced risk for breast cancer, but the mechanisms are unclear. We tested the hypothesis that soy isoflavones, which have ovarian hormone-like effects, can reduce fibroglandular breast tissue (FGBT, 'breast density'), a strong risk marker for breast cancer. METHODS: Premenopausal women (age 30-42 years) were randomized to consume isoflavones (136.6 mg as aglycone equivalents, n = 99) or placebo (n = 98) for 5 days per week up to 2 years, and changes in breast composition measured by magnetic resonance imaging at baseline and yearly intervals were compared after square root transformation using linear mixed effects regression models. RESULTS: By intention-to-treat analyses (n = 194), regression coefficients (ß estimates) of the interaction of time and isoflavone treatment were -0.238 (P = 0.06) and -0.258 (P < 0.05) before and after BMI adjustment, respectively for FGBT, 0.620 (P < 0.05) and 0.248 (P = 0.160), respectively for fatty breast tissue (FBT), and -0.155 (P < 0.05) and -0.107 (P < 0.05), respectively for FGBT as percent of total breast (FGBT%). ß Estimates for interaction of treatment with serum calcium were -2.705 for FBT, and 0.588 for FGBT% (P < 0.05, before but not after BMI adjustment). BMI (not transformed) was related to the interaction of treatment with time (ß = 0.298) or with calcium (ß = -1.248) (P < 0.05). Urinary excretion of isoflavones in adherent subjects (n = 135) significantly predicted these changes in breast composition. Based on the modeling results, after an average of 1.2, 2.2 and 3.3 years of supplementation, a mean decrease of FGBT by 5.3, 12.1, and 19.3 cc, respectively, and a mean decrease of FGBT% by 1.37, 2.43, and 3.50%, respectively, were estimated for isoflavone exposure compared to placebo treatment. Subjects with maximum isoflavone excretion were estimated to have 38 cc less FGBT (or ∼3.13% less FGBT%) than subjects without isoflavone excretion. Decrease in FGBT and FGBT% was more precise with daidzein than genistein. CONCLUSIONS: Soy isoflavones can induce a time- and concentration-dependent decrease in FGBT, a biomarker for breast cancer risk, in premenopausal women, and moderate effects of calcium on BMI and breast fat, suggesting a beneficial effect of soy consumption.

An electronic medical record-based intervention to improve hepatitis A vaccination rates in the emergency department during a regional outbreak.

BACKGROUND: In response to the severe hepatitis A outbreak that occurred in Michigan between August 2016 and September 2019, our multihospital health system implemented an electronic medical record (EMR)-based vaccination intervention across its nine emergency departments (EDs). The objectives were to explore the impact of this intervention on increasing vaccination rates among high-risk individuals and to assess the barriers to use of a computerised vaccine reminder system. METHODS: All patients who were 18 years or older were screened using an electronic nursing questionnaire. If a patient was at high risk based on the questionnaire, an electronic best practice advisory (BPA) would trigger and give the physician or advanced practice provider the option to order the hepatitis A vaccine. We explored the vaccination rates in the 24-month preintervention and the 18-month intervention periods. We then administered a survey to physicians, advanced practice providers and nurses evaluating their perceptions and barriers to use of the EMR intervention. RESULTS: During the preintervention period, 49 vaccines were ordered (5.5 per 100 000 patient visits) and 32 were administered (3.6 per 100 000 patient visits). During the intervention period, 574 865 patient visits (74.3%) were screened. 2494 vaccines (322 per 100 000 patient visits) were ordered, and 1205 vaccines (155 per 100 000 patients visits) were administered. Physicians and advanced practice providers were initially compliant with the BPA's use, but compliance declined over time. Surveys revealed that the major barrier to use was lack of time. CONCLUSIONS: EMR screening tools and BPAs can be used in the ED as an effective strategy to vaccinate high-risk individuals. This may be translatable to outbreaks of other vaccine-preventable illnesses like influenza, measles or SARS-CoV-2. Providing ongoing education about the public health initiative and giving feedback to physicians, advanced practice providers and nurses about tool compliance are needed to sustain the improvement over time.

Feasibility Study of Caregiver-Provided Life Review: Implementation, Adaptation, and Effects on Care Recipients' Depressive Symptoms.

OBJECTIVES: This study aimed to examine the feasibility of unpaid, family/friend caregivers conducting life reviews with people with dementia in long-term care and community settings and reported on how we adapted the intervention modality under the COVID-19 pandemic. METHODS: Twenty-one caregiver-care recipient dyads completed 6 weekly life review sessions. The intervention format was modified to accommodate COVID-19 restrictions. Primary and secondary outcome measures were analyzed based on repeated measures at baseline and post-intervention. RESULTS: Due to the changing nature of the pandemic, we iterated the caregiver training intervention four times to accommodate caregivers' needs while having faced multiple recruitment challenges with care facility residents. Care recipients' depression appeared to have improved (p = .001). CONCLUSIONS: Although the COVID-19 pandemic created unique recruitment challenges, all the care recipients seemed to enjoy the life review activities supported by the positive outcomes in gaining socialization opportunities. It may be beneficial to offer a more self-paced intervention modality to ease the burden on caregivers. CLINICAL IMPLICATIONS: It appears that unpaid family/friend caregivers can provide life reviews to their loved ones with dementia. Training the caregivers on how to provide life reviews can be an easy, low-risk activity that might ameliorate depressive symptoms in the care recipients.

Risk Factors for Midline Catheter Failure: A Secondary Analysis of an Existing Trial.

Objective: While midline catheters (MCs) are considered to be a reliable form of vascular access, up to 25% of the placements culminate in failure. We aimed to explore risk factors for MC failure. Methods: We performed an analysis of existing randomized controlled trial data involving a comparison of two midline catheters. The study aimed to assess risk factors related to MC failure, including patient, procedure, catheter, and vein characteristics. Cox regression was used for univariable and multivariable analyses to evaluate the association between characteristics and MC failure. Results: Among 191 patients that were included in this secondary analysis, more patients were female (114/191 [59.7%]) and average age was 60.2 (SD = 16.7) years. Clinical indications for MC placement included antibiotics (60.7%), difficult venous access (32.5%), or both (6.8%). In a univariable Cox regression analysis, the increase in pulse rate (HR 1.02; 95% CI, 1.00-1.04; P=0.02), temperature ≥38°C (HR 5.59; 95% CI, 1.96-15.94; P=0.001), oxygen saturation <93% (HR 2.91; 95% CI, 1.03-8.24; P=0.04), norepinephrine in dextrose infusion (HR 2.41; 95% CI, 1.17-4.97; P=0.02) and cephalic vein insertion (HR, 2.47; 95% CI, 1.09-5.57; P=0.03) were all associated with higher risk of MC failure. In a multivariable Cox model, difficult venous access (aHR 2.05; 95% CI, 1.04-4.05; P=0.04) and norepinephrine in dextrose (aHR 2.29; 95% CI, 1.09-4.82; P=0.03) was associated with catheter failure. Conclusion: Elevated pulse rate, decreased oxygen saturation level, temperature ≥38°C, and norepinephrine use were each associated with an increased risk of MC failure. These factors should be considered when selecting the most appropriate vascular access device for individual patients. Additionally, the cephalic vein insertion has the highest risk for MC failure and other access points could be preferentially considered.

Relationship Between Diabetes-Related Complications and Sleep Complaints in Older Mexican Americans.

INTRODUCTION/OBJECTIVE: The prevalence of Type 2 Diabetes Mellitus is increasing in the older American population, especially Mexican Americans. Sleep disorders are common in older adults with T2DM. This study examined the relationship between T2DM-related complications and sleep complaints in older Mexican Americans over 9 years of follow-up. METHODS: Study included 310 participants aged 77 years or older with self-reported diabetes from the Hispanic Established Population for the Epidemiological Study of the Elderly (2007/08-2016). RESULTS: Of the 310 participants, the mean age was 82.04 years. The cohort had significantly more females (69.03%) than males (30.97%). A substantial number of participants had trouble falling asleep (16.13%), waking up several times (36.45%), trouble staying asleep (15.16%), and feeling tired and worn out after waking up (12.90%). The percent of diabetes complications were 70.2% for circulation problems, 58.2% for eye disorders, 15.9% for kidney disease, and 4.4% for amputation. Participants who experienced sleep complaints for 15 or more days in a month were more likely to experience diabetic complications. DISCUSSION: This study demonstrated a significant relationship between T2DM macro- and micro-vascular complications and increased risk of sleep disorders in older Mexican Americans.

Predictors of ultrasound-guided peripheral intravenous catheter failure: A secondary analysis of existing trial data.

OBJECTIVES: Ultrasound-guided (US) peripheral intravenous catheters (PIVC) have a high failure rate with many failing prior to completion of therapy. Risk factors associated with catheter failure are poorly delineated. This study aimed to assess risk factors related to catheter failure including patient, procedure, catheter, and vein characteristics to further elucidate which variables may impact catheter longevity. METHODS: This was a secondary analysis using an existing trial dataset that primarily compared survival of two catheters: a standard long (SL) and an ultra-long (UL) US PIVC. Adult emergency room patients with difficult intravenous access at a tertiary care suburban academic center were study participants. Kaplan-Meier was employed to estimate the median catheter survival time. Cox regression univariable and multivariable analyses were used to evaluate the primary outcome of catheter survival. RESULTS: Among 257 subjects, 63% of PIVCs survived until completion of therapy. In a multivariable Cox regression model, length of catheter in vein >2.75 cm (adjusted hazard ratio [aHR] 0.58, 95% confidence interval [CI] 0.37-0.90, p = 0.01) was associated with improved survival. First stick success decreased the risk of catheter failure (aHR 0.68, 95% CI 0.44-1.06, p = 0.09) but was not statistically significant. Factors associated with the increased risk of catheter failure included: depth of vein >1.2 cm (aHR 1.68, 95% CI 1.06-2.66, p = 0.03) and PIVC placement in right extremity (aHR 1.64, 95% CI 1.07-2.51, p = 0.02). CONCLUSIONS: This study demonstrated that catheter length in vein (>2.75 cm) was associated with improved US PIVC survival highlighting the value of longer catheters in US PIVC survival. Choosing targets in the non-dominant extremity with shallower depths (⩽1.2 cm) may also increase catheter survival.

Examining D-dimer and Empiric Anti-coagulation in COVID-19-Related Thrombosis.

Objective Thrombosis is thought to occur frequently in the setting of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We aimed to elucidate the relationship between macro/microvascular thrombosis, D-dimer levels, and empiric anticoagulation in coronavirus disease 2019 (COVID-19). Methods This was an exploratory prospective, single-site, observational study. Adult emergency department patients with COVID-19 requiring hospitalization received a point-of-care lower extremity venous duplex ultrasound. The primary endpoint was thromboembolism and associated D-dimer level. Secondary endpoints included rates of micro and macro thrombotic complications as well as empiric anticoagulant use. Results Between January 13th and April 12th 2021, 52 patients were enrolled. Median D-dimer at presentation was 650 ng/mL (range 250-10,000 ng/mL) among patients with negative duplex studies. During hospitalization, 18 patients underwent 20 additional studies assessing for venous thromboembolism (VTE). These studies yielded one deep vein thrombosis (DVT) diagnosis. Among patients with negative studies median D-dimer was 1,246 ng/mL (range 329-10,000 ng/mL). Two patients experienced microvascular complications. Seven patients were started on empiric full dose anticoagulation. Conclusion While VTE remains a major concern amongst patients with COVID-19, the normal D-dimer cut off of >500 ng/mL likely should not be used to initiate further VTE workup. Additionally, moderately elevated D-dimer did not correlate strongly with microvascular complications and may not be relevant in the decision to initiate empiric anticoagulation.

Predictors of hospitalization and severe disease due to breakthrough SARS-CoV-2 infection in fully vaccinated individuals.

Objective: We aimed to identify risk factors for hospital admission and severe disease among fully vaccinated (FV) individuals with COVID-19. Further, we investigated if risk factors for hospitalization and severe disease are similar between unvaccinated (UV) and vaccinated individuals. Methods: This was a multicenter, observational cohort analysis from a large regional healthcare system in metro Detroit using electronic health record data to evaluate risk factors for hospitalization and severe COVID-19 disease. Vaccination data were retrieved using electronic medical records linked to our statewide immunization database. Consecutive adult FV and UV patients with a primary admission diagnosis of COVID-19 were included in the comparative analysis. Partially vaccinated patients and patients who had received a booster dose were excluded. The primary outcome of this study was hospital admission and severe disease inclusive of intensive care unit (ICU) admission, mechanical ventilation, or death. Results: Between December 15, 2020 and December 19, 2021, 20,584 emergency department visits met our inclusion criteria. Among these, 2005 (9.7%) visits consisted of FV individuals, 18,579 (90.3%) were UV, and 40.3% of UV and 52.7% of FV required hospitalization with similar (12.7% and 12.6%, respectively) rates of severe disease. Hospitalized UV patients with severe disease were younger than their FV counterparts (49.5% <65 years vs. 13.5% p < 0.001). Risk factors for severe disease on UV and FV included age ≥65 years (UV: adjusted odds ratio [aOR] 1.49, 95% confidence interval [CI] 1.28-1.73, p < 0.001 and FV: aOR 2.50, 95% CI 1.44-4.36 p = 0.001) and weighted Elixhauser score >10 (UV: aOR 9.11, 95% CI 6.92-12.00, p < 0.001 and FV: aOR 6.04, 95% CI 2.68-13.26, p < 0.001). However, only on UV status, body mass index (BMI) ≥30 kg/m2 was associated with increased odds of severe disease (aOR 2.59, 95% CI 2.09-3.22, p < 0.001). Conclusions: FV patients with breakthrough SARS-CoV-2 infection who require hospitalization and have severe disease are older and have more medical comorbidities compared to UV patients. When comparing risk factors for severe disease between UV and FV individuals, FV status is particularly associated with reduced risk among patients with a BMI ≥30 kg/m2 and a moderate number of medical comorbidities, regardless of age, highlighting the importance of vaccination in these particularly vulnerable groups.
