Managing Antimicrobial Resistance in the Emergency Department.

(Basic awareness and understanding of antimicrobial resistance and prevailing mechanisms can aid emergency physicians in providing appropriate care to patients with infections due to a multidrug-resistant organism (MDRO). Empiric treatment of MDRO infections should be approached with caution and guided by the most likely pathogens based on differential diagnosis, severity of the illness, suspected source of infection, patient-specific factors, and local antibiotic susceptibility patterns. Newer broad-spectrum antibiotics should be reserved for critically ill patients where there is a high likelihood of infection with an MDRO.).

Awareness with paralysis and symptoms of post-traumatic stress disorder among mechanically ventilated emergency department survivors (ED-AWARENESS-2 Trial): study protocol for a pragmatic, multicenter, stepped wedge cluster randomized trial.

BACKGROUND: Awareness with paralysis (AWP) is memory recall during neuromuscular blockade (NMB) and can cause significant psychological harm. Decades of effort and rigorous trials have been conducted to prevent AWP in the operating room, where prevalence is 0.1-0.2%. By contrast, AWP in mechanically ventilated emergency department (ED) patients is common, with estimated prevalence of 3.3-7.4% among survivors given NMB. Longer-acting NMB use is a critical risk for AWP, and we have shown an association between ED rocuronium use and increased AWP prevalence. As NMB are given to more than 90% of ED patients during tracheal intubation, this trial provides a platform to test an intervention aimed at reducing AWP. The overall objective is to test the hypothesis that limiting ED rocuronium exposure will significantly reduce the proportion of patients experiencing AWP. METHODS: This is a pragmatic, stepped wedge cluster randomized trial conducted in five academic EDs, and will enroll 3090 patients. Per the design, all sites begin in a control phase, under observational conditions. At 6-month intervals, sites sequentially enter a 2-month transition phase, during which we will implement the multifaceted intervention, which will rely on use of nudges and defaults to change clinician decisions regarding ED NMB use. During the intervention phase, succinylcholine will be the default NMB over rocuronium. The primary outcome is AWP, assessed with the modified Brice questionnaire, adjudicated by three independent, blinded experts. The secondary outcome is the proportion of patients developing clinically significant symptoms of post-traumatic stress disorder at 30 and 180 days after hospital discharge. We will also assess for symptoms of depression and anxiety, and health-related quality of life. A generalized linear model, adjusted for time and cluster interactions, will be used to compare AWP in control versus intervention phases, analyzed by intention-to-treat. DISCUSSION: The ED-AWARENESS-2 Trial will be the first ED-based trial aimed at preventing AWP, a critical threat to patient safety. Results could shape clinical use of NMB in the ED and prevent more than 10,000 annual cases of AWP related to ED care. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT05534243 .

The SQuID protocol (subcutaneous insulin in diabetic ketoacidosis): Impacts on ED operational metrics.

BACKGROUND: Studies using fast-acting subcutaneous (SQ) insulin analogs in diabetic ketoacidosis (DKA) have demonstrated efficacy, safety, and cost-effectiveness, allowing treatment of mild-to-moderate (MTM)-severity DKA patients in non-intensive care unit (ICU) settings. However, emergency department (ED)-based studies are few, with limited exploration of impacts on operational metrics. METHODS: We implemented the SQuID (Subcutaneous Insulin in Diabetic Ketoacidosis) protocol for adults with MTM-severity DKA in an urban academic ED, collecting data from August 1, 2021, to February 28, 2022. We examined fidelity (frequency of required q2h glucose checks), safety (proportion of patients administered rescue dextrose for hypoglycemia), and ED length of stay (EDLOS) for the SQuID cohort compared to patients (non-ICU) treated with a traditional insulin infusion. We also examined ICU admission rate among MTM-severity DKA patients after introduction of SQuID to two historical control periods (pre-intervention and pre-COVID). We used Mann-Whitney U to test for differences in EDLOS distributions, bootstrapped (n = 1000) confidence intervals (CIs) for EDLOS median differences, and the two-sample z-test for differences in ICU admissions. RESULTS: We identified 177 MTM-severity DKA patients in the study period (78 SQuID, 99 traditional cohort) and 163 preintervention and 161 pre-COVID historical control patients. Fidelity to the SQuID pathway was good, with glucose checks exceeding the q2-h requirement. We found no difference in the proportion of rescue dextrose administration compared to the traditional pathway. We observed significant reductions in median EDLOS for the SQuID cohort compared to the traditional cohort during the study period (-3.0, 95% CI -8.5 to -1.4), the preintervention period (-1.4, 95% CI -3.1 to -0.1), and the pre-COVID control period (-3.6, 95% CI -7.5 to -1.8). CONCLUSIONS: In this single-center study at an academic ED, treatment of patients with MTM-severity DKA with a SQ insulin protocol was effective, demonstrated equivalent safety, and reduced ED length of stay.

Awareness With Paralysis Among Critically Ill Emergency Department Patients: A Prospective Cohort Study.

OBJECTIVES: In mechanically ventilated patients, awareness with paralysis (AWP) can have devastating consequences, including post-traumatic stress disorder (PTSD), depression, and thoughts of suicide. Single-center data from the emergency department (ED) demonstrate an event rate for AWP factors higher than that reported from the operating room. However, there remains a lack of data on AWP among critically ill, mechanically ventilated patients. The objective was to assess the proportion of ED patients experiencing AWP and investigate modifiable variables associated with its occurrence. DESIGN: An a priori planned secondary analysis of a multicenter, prospective, before-and-after clinical trial. SETTING: The ED of three academic medical centers. PATIENTS: Mechanically ventilated adult patients that received neuromuscular blockers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: All data related to sedation and analgesia were collected. AWP was the primary outcome, assessed with the modified Brice questionnaire, and was independently adjudicated by three expert reviewers. Perceived threat, in the causal pathway for PTSD, was the secondary outcome. A total of 388 patients were studied. The proportion of patients experiencing AWP was 3.4% ( n = 13), the majority of whom received rocuronium ( n = 12/13; 92.3%). Among patients who received rocuronium, 5.5% ( n = 12/230) experienced AWP, compared with 0.6% ( n = 1/158) among patients who did not receive rocuronium in the ED (odds ratio, 8.64; 95% CI, 1.11-67.15). Patients experiencing AWP had a higher mean ( sd ) threat perception scale score, compared with patients without AWP (15.6 [5.8] vs 7.7 [6.0]; p < 0.01). CONCLUSIONS: AWP was present in a concerning proportion of mechanically ventilated ED patients, was associated with rocuronium exposure in the ED, and led to increased levels of perceived threat, placing patients at greater risk for PTSD. Studies that aim to further quantify AWP in this vulnerable population and eliminate its occurrence are urgently needed.

Adjusted vs Total Body Weight-Based Dosing of Sedation and Analgesia Used in the Intensive Care Unit.

Background: The purpose of this study was to evaluate if dosing fentanyl, dexmedetomidine, and propofol based on ideal or adjusted vs actual weight in patients would decrease overall opioid and sedative use. Methods: This was a retrospective chart review comparing adjusted vs actual weight-based dosing protocol of mechanically ventilated (MV) intensive care unit (ICU) adult patients who required fentanyl and either propofol or dexmedetomidine. Results: A total of 261 patients were included in which 101 patients were in the actual weight group and 160 patients were in the adjusted weight group. Total doses per MV day of fentanyl was 1042 ± 1060 µg in the actual weight group vs 901 ± 1025 µg in the adjusted weight group (P = .13). Total doses per MV day of midazolam was 20 ± 19 mg in the actual group vs 15 ± 19 mg adjusted group (P = .02). Average MV days was 8.2 vs 7.1 days, ICU length of stay was 10.6 vs 9.4 days, and self-extubation rates were 17.8% vs 4.4% in the actual group and adjusted group, respectively. Conclusion: Total midazolam doses per MV day were lower in the adjusted group. No significant change was seen in MV days, ICU length of stay, or self-extubation rates.

Change in Management of Status Epilepticus With the Addition of Neurointensivist-Led Neurocritical Care Team at a Rural Academic Medical Center.

Learning Objective: Status epilepticus (SE) is continuous clinical and/or electrographic seizures lasting 5 minutes or more without recovery and carries a high mortality. Medication management varies by institution, as well as administration, combination of antiepileptic drugs (AEDs), and dosing. Methods: Single-center retrospective review of medication management of SE patients admitted to West Virginia University Hospital before and after neurointensivist implemented guidelines. Patients admitted between January 2012 and June 2014 were grouped in the prior to neurointensivist group (pre-NI) and patients admitted between July 2014 and June 2016 were grouped in the postneurointensivist group (post-NI). Baseline demographics, hospital, intensive care unit (ICU), and ventilator length of stay were recorded. Medications reviewed included number of AEDs and maximum dose of lorazepam, phenytoin, levetiracetam, and lacosamide. Outcomes included number of continuous infusions of either midazolam or propofol at seizure suppression doses as well as pentobarbital, phenobarbital, or ketamine, and need for vasopressor use. Results: Of the 74 patients included, the pre-NI group (n = 40) utilized more AEDs (6 vs 4) compared with the post-NI group (n = 34). The pre-NI group had less midazolam continuous infusions meeting seizure suppression doses (8 vs 9), but higher average doses (49 vs 27 mg/h) compared with the post-NI group. More patients in the pre-NI group were on propofol seizure suppression doses (15 vs 10) and phenobarbital continuous infusions (11 vs 2) than the post-NI group. Patients had less vasopressor use in the post-NI group than the pre-NI group (11 vs 23). Frequency and dosing of lorazepam, phenytoin, levetiracetam, and lacosamide were similar between the 2 groups. Ventilator use, hospital, and ICU length of stay were also similar between groups. Discussion: Implementation of a neurointensivist and medication guidelines resulted in fewer AEDs and less vasopressor use in the management of SE. Midazolam use was slightly higher in the post-NI group but at lower doses overall.

Utilizing Clinical Pharmacy Specialists to Address Access to Care Barriers in the Veteran Population for the Management of Diabetes.

OBJECTIVE: To show that clinical pharmacy specialists (CPSs) can be utilized in remote facilities to provide appropriate diabetes outcomes along with potential cost savings. METHODS: A retrospective cohort chart review conducted at the Veterans Affairs North Texas Healthcare System (VANTHCS) evaluated outcomes in patients with type 2 diabetes mellitus referred to CPSs at Fort Worth Outpatient Clinic (FWOPC) or the endocrinologist-managed specialty clinic at the Dallas VA Medical Center (DVAMC). The primary outcome was percentage of patients reaching hemoglobin A1c (HbA1c) goal of <8%. Secondary outcomes were percentage of patients reaching HbA1c <7%, time to reach HbA1c goals of <8% and <7%, and cost savings. RESULTS: There was no statistically significant difference in the number of patients reaching HbA1c goal <8% in the FWOPC (65.3%) compared to the DVAMC (55.8%). Secondary end points comparing FWOPC and DVAMC found no difference in patients reaching HbA1c <7% (20.8% vs 19.2%) and time to reach HbA1c goal of <8% (4.5 vs 6 months) and <7% (8.5 vs 7.5 months). Cost-saving analysis demonstrated a composite of US$350 292 could be saved by the VANTHCS facility if patients continued to be referred to CPS. CONCLUSION: CPSs can be utilized in diabetes management to provide similar health outcomes as the endocrinologist-managed clinic and to potentially allow for facility cost savings.
