Quality Improvement Initiative to Increase Modality Education in a Nephrology Clinic During the COVID-19 Pandemic.

Low attendance by patients with advanced chronic kidney disease (CKD stage 4 and 5) to the kidney replacement therapy (KRT) education sessions was noted by our nurse practitioners at a safety net hospital. The main outcome measure was the weekly percentage of patients with advanced CKD seen by the nephrology division weekly that completed KRT education. Process measures were weekly KRT session attendance by scheduled patients and the weekly referral of patients to KRT education sessions. The weekly education class attendance by scheduled patients reached the target level. This quality improvement project resulted in patients having access to virtual education sessions that helped provide distanced education during the COVID-19 pandemic, and benefitted patients living further away or needing more flexible options due to work and other commitments even in post-pandemic times. Making virtual visits available reduces travel cost for the person as well.

Implementation of a pilot novel objective peer comparison evaluation system in an emergency medicine residency program.

Objectives: Emergency medicine (EM) residents are currently evaluated via The Milestones, which have been shown to be imperfect and subjective. There is also a need for residents to achieve competency in patient safety and quality improvement processes, which can be accomplished through provision of peer comparison metrics. This pilot study aimed to evaluate the implementation of an objective peer comparison system for metrics that quantified aspects of quality and safety, efficiency and throughput, and utilization. Methods: This pilot study took place at an academic, tertiary care center with a 3-year residency and 14 residents per postgraduate year (PGY) class. Metrics were compared within each PGY class using Wilcoxon signed-rank and rank-order analyses. Results: Significant changes were seen in the majority of the metrics for all PGY classes. PGY3s accounted for the significant change in EKG and X-ray reads, while PGY1s and PGY2s accounted for the significant change in disposition to final note share. Physician evaluation to disposition decision was the only metric that did not reach significance in any class. Conclusions: These preliminary data suggest that providing objective metrics is possible. Peer comparison metrics could provide an effective objective addition to the milestone evaluation system currently in use.

Impact of COVID-19 and Shelter in Place on Volume and Type of Traumatic Injuries.

INTRODUCTION: Very little is known about the effects of the novel coronavirus (COVID-19) pandemic and its associated social distancing practices on trauma presentations to the emergency department (ED). This study aims to assess the impact of a city-wide stay at home order on the volume, type, and outcomes of traumatic injuries at urban EDs. METHODS: The study was a retrospective chart review of all patients who presented to the ED of an urban Level I Trauma Center and its urban community affiliate in the time period during the 30 days before the institution of city-wide shelter-in-place (preSIP) order and 60 days after the shelter-in-place (SIP) order and the date-matched time periods in the preceding year. Volume and mechanism of traumatic injuries were compared using paired T-tests. RESULTS: There was a significant decrease in overall ED volume. The volume of certain blunt trauma presentations (motor vehicle collisions) during the first 60 days of SIP compared to the same period from the year prior also significantly decreased. Importantly, the volume of penetrating injuries, including gunshot wounds and stab wounds, did not differ for the preSIP and SIP periods when compared to the prior year. The mortality of traumatic injuries was also unchanged during the SIP comparison period. CONCLUSION: While there were significant decreases in visits to the ED and overall trauma volume, penetrating trauma, including gun violence, and other severe traumatic injuries remain a public health crisis that affects urban communities despite social distancing recommendations enacted during the COVID-19 pandemic.

Rate of Decompensation of Normoxic Emergency Department Patients with SARS-CoV-2.

INTRODUCTION: As of October 30, 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected over 44 million people worldwide and killed over 1.1 million people. In the emergency department (ED), patients who need supplemental oxygen or respiratory support are admitted to the hospital, but the course of normoxic patients with SARS-CoV-2 infection is unknown. In our health system, the policy during the coronavirus 2019 (COVID-19) pandemic was to admit all patients with abnormal chest imaging (CXR) regardless of their oxygen level. We also admitted febrile patients with respiratory complaints who resided in congregate living. We describe the rate of decompensation among patients admitted with suspected SARS-CoV-2 infection but who were not hypoxemic in the ED. METHODS: This is a retrospective observational study of patients admitted to our health system between March 1-May 5, 2020 with suspected SARS-CoV-2 infection. We queried our registry to find patients who were admitted to the hospital but had no recorded oxygen saturation of <92% in the ED and received no supplemental oxygen prior to admission. Our primary outcome was decompensation at 72 hours, defined by the need for respiratory support (oxygen, high-flow nasal cannula, non-invasive ventilation, or intubation). RESULTS: A total of 840 patients met our inclusion criteria. Of those patients, 376 (45%) tested positive for SARS-CoV-2. Sixty patients (7.1%) with suspected COVID-19 required respiratory support at 72 hours including 27 (3%) of confirmed SARS-CoV-2 positive patients. Among the 376 patients who tested positive for SARS-CoV-2, 54 patients (14%) had normal CXR in the ED. One-third of patients with normal CXRs decompensated at 72 hours. Seven SARS-CoV-2 positive patients in our cohort died during their hospitalization, of whom five had normal CXRs on admission. CONCLUSION: Sixty (7.1%) of suspected COVID-19 patients hospitalized at 72 hours required respiratory support despite being normoxic in the ED. Further research should look to identify the normoxic SARS-CoV-2 patients at risk for decompensation.

Impact of a shelter-in-place order during the COVID-19 pandemic on the incidence of opioid overdoses.

INTRODUCTION: Since the beginning of the novel coronavirus (COVID-19) pandemic in the United States, there have been concerns about the potential impact of the pandemic on persons with opioid use disorder. Shelter-in-place (SIP) orders, which aimed to reduce the spread and scope of the virus, likely also impacted this patient population. This study aims to assess the role of the COVID-19 pandemic on the incidence of opioid overdose before and after a SIP order. METHODS: A retrospective review of the incidence of opioid overdoses in an urban three-hospital system was conducted. Comparisons were made between the first 100 days of a city-wide SIP order during the COVID-19 pandemic and the 100 days during the COVID-19 pandemic preceding the SIP order (Pre-SIP). Differences in observed incidence and expected incidence during the SIP period were evaluated using a Fisher's Exact test. RESULTS: Total patient visits decreased 22% from 46,078 during the Pre-SIP period to 35,971 during the SIP period. A total of 1551 opioid overdoses were evaluated during the SIP period, compared to 1665 opioid overdoses during the Pre-SIP period, consistent with a 6.8% decline. A Fisher's Exact Test demonstrated a p < 0.0001, with a corresponding Odds Ratio of 1.20 with a 95% confidence interval (1.12;1.29). CONCLUSION: The COVID-19 pandemic and the associated SIP order were associated with a statistically and clinically significant increase in the proportion of opioid overdoses in relation to the overall change in total ED visits.

Emergency department medication dispensing reduces return visits and admissions.

OBJECTIVES: Return visits to the emergency department (ED) and subsequent readmissions are common for patients who are unable to fill their prescriptions. We sought to determine if dispensing medications to patients in an ED was a cost-effective way to decrease return ED visits and hospital admissions for skin and soft tissue infections (SSTIs). METHODS: A retrospective review of ED visits for SSTIs, during the 24 weeks before and after the implementation of a medication dispensing program, was conducted. Charts were analyzed for both ED return visits and hospital admissions within 7 days and 30 days of the initial ED visit. Return visits were further reviewed to determine if the clinical conditions on subsequent visits were related to the initial ED presentation. A cost analysis comparing the cost of treatment to cost savings for return visits was also performed. RESULTS: Before the implementation of the medication dispensing program, the return rate in 7 days for the same condition was 9.1% and the rate of admission was 2.8%. The return rate for the same condition in 8-30 days was 2.1% and the rate of admission was 1.0%. After the implementation of the medication dispensing program, the return rate for the same condition in 7 days was 8.0%, and the admission rate was 1.7%. The return rate for the same condition in 8-30 days was 0.8%, and the admission rate was 0%. The total cost of dispensed medications was $4050, while total cost savings were estimated to be $95,477. CONCLUSION: A medication dispensing program in the ED led to a reduction in return visits and admissions for SSTIs at both 7 days and 30 days. For a cost of only $4050, an estimated total of $95,477 was saved. A medication dispensing program is a cost-effective way to reduce return visits to the ED and subsequent admissions for certain conditions.

An Unlikely Cause of Abdominal Pain.

Cecal bascule is a rare subtype of cecal volvulus where the cecum folds anterior to the ascending colon causing intestinal obstruction. It is a challenging diagnosis to make in the emergency department, as the mobile nature of the cecum leads to a great deal of variation in its clinical presentation. Our discussion of a 78-year-old female who presented with abdominal pain and was found to have a cecal bascule requiring right hemicolectomy, demonstrates how emergency physicians must expand their differential diagnosis for patients reporting signs of intestinal obstruction. Though cecal bascule does not present often, the need for early surgical intervention necessitates a high level of clinical suspicion to prevent life-threatening complications.

Impact of an Opioid Prescribing Guideline in the Acute Care Setting.

BACKGROUND: Death from opioid abuse is a major public health issue. The death rate associated with opioid overdose nearly quadrupled from 1999 to 2008. Acute care settings are a major source of opioid prescriptions, often for minor conditions and chronic noncancer pain. OBJECTIVE: Our aim was to determine whether a voluntary opioid prescribing guideline reduces the proportion of patients prescribed opioids for minor and chronic conditions. METHODS: A retrospective chart review was performed on records of adult emergency department visits from January 2012 to July 2014 for dental, neck, back, or unspecified chronic pain, and the proportion of patients receiving opioid prescriptions at discharge was compared before and after the guideline. Attending emergency physicians were surveyed on their perceptions regarding the impact of the guideline on prescribing patterns, patient satisfaction, and physician-patient interactions. RESULTS: In our sample of 13,187 patient visits, there was a significant (p < 0.001) and sustained decrease in rates of opioid prescriptions for dental, neck, back, or unspecified chronic pain. The rate of opioid prescribing decreased from 52.7% before the guideline to 29.8% immediately after its introduction, and to 33.8% at an interval of 12 to 18 months later. The decrease in opioid prescriptions was observed in all of these diagnosis groups and in all age groups. All 31 eligible prescribing physicians completed a survey. The opioid prescribing guideline was supported by 100% of survey respondents. CONCLUSIONS: An opioid prescribing guideline significantly decreased the rates at which opioids were prescribed for minor and chronic complaints in an acute care setting.

Randomized trial comparing intraoral ultrasound to landmark-based needle aspiration in patients with suspected peritonsillar abscess.

OBJECTIVES: Traditionally, emergency physicians (EPs) have used anatomic landmark-based needle aspiration to drain peritonsillar abscesses (PTAs). If this failed, an imaging study and/or consultation with another service to perform the drainage is obtained. Recently, some EPs have used ultrasound (US) to guide PTA drainage. This study seeks to determine which initial approach leads to greater successful drainage. The primary objective of this study was to compare the diagnostic accuracy of EPs for detecting PTA or peritonsillar cellulitis (PTC) using either intraoral US or initial needle aspiration after visual inspection (the landmark technique [LM]). Secondary objectives included the successful aspiration of purulent material in those patients with a PTA in each arm, the use of computed tomography (CT) scanning in each arm, and the otolaryngology (ENT) consultation rate in each arm. METHODS: This was a prospective, randomized, controlled clinical trial of a convenience sample of adult patients who presented to a single, large, urban university hospital. Patients were enrolled if they presented with a constellation of signs and symptoms that were judged to be a PTA. These patients were randomized to receive intraoral US or to undergo LM drainage. The US was performed using an 8-5 MHz intracavitary transducer immediately prior to the procedure. The probe was then withdrawn and the provider who did the US also performed the needle aspiration. The LM was performed using visual landmarks in a superior to inferior approach until pus was obtained or at least two sticks were performed. Anesthesia was standardized. Patients returned for follow-up in 2 days where a final diagnosis was rendered. RESULTS: There were 28 patients enrolled, with 14 in each arm. US established the correct diagnosis more often than LM [(100%, 95% confidence interval [CI] = 75% to 100% vs. 64%, 95% CI = 39% to 84%; p = 0.04)]. US also led to more successful aspiration of purulent material by the EP than LM in patients with PTA [(100%, 95% CI =63% to 100% vs. 50%, 95% CI = 24% to 76%; p = 0.04)]. The ENT consult rate was 7% (95% CI = 0% to 34%) for US versus 50% (95% CI = 27% to 73%) for LM (p = 0.03). The CT usage rate was 0% for US versus 35% for LM (p = 0.04). CONCLUSIONS: An initial intraoral US performed by EPs can reliably diagnose PTC and PTA. Additionally, using intraoral US to assist in the drainage of PTAs with needle aspiration leads to greater success compared to the traditional method of LM relying on physical exam alone.

Ultrasound-guided peripheral venous access vs. the external jugular vein as the initial approach to the patient with difficult vascular access.

BACKGROUND: Traditionally, Emergency Physicians (EPs) have used the external jugular (EJ) vein to gain vascular access in patients who have failed nursing attempts at peripheral access. Recently, some EPs have used ultrasound (USIV) to gain peripheral access. STUDY OBJECTIVE: This study seeks to determine which initial approach by EPs would lead to greater success. METHODS: This was a prospective, randomized study of all adult patients who presented to the Emergency Department (ED) between June and December 2007. Inclusion criteria were failed nursing attempts at peripheral access (at least three). EPs were 2(nd)- or 3(rd)-year residents who had previously performed more than five each of EJs and USIVs. Patients were randomized into either an initial EJ or USIV approach. RESULTS: Sixty patients were enrolled, 32 in the ultrasound group, 28 in the EJ group. Fifteen different EPs performed access. Initial Success: USIV 84% (95% confidence interval [CI] 68-93%) vs. EJ 50% (95% CI 33-67%), p = 0.006. Success if EJ visible: USIV 84% vs. EJ 66% (p = 0.18). Overall success, including data from the crossover pathway: a total of 41 lines were successfully placed by ultrasound out of 46 attempts (89%) vs. 18 out of 33 for EJ (55%), p = 0.001. In total, 59/60 patients (98%) had a peripheral i.v. successfully placed. The percentage of functioning lines when the patient left the ED was: USIV 89% (95% CI 72-96%) vs. EJ 93% (95% CI 68-98%), p = 0.88. CONCLUSION: As an initial approach to all patients with difficult venous access, ultrasound-guided peripheral lines are superior to the EJ approach. However if the EJ was visible, there was no difference in success among the initial approaches. Both techniques, when used together, could achieve peripheral vascular access in 98% of difficult access patients.

Comparison of ultrasound-guided and standard landmark techniques for knee arthrocentesis.

BACKGROUND: Ultrasound is a useful adjunct to many Emergency Department (ED) procedures. Arthrocentesis is typically performed using a landmark technique but ultrasound may provide an opportunity to improve arthrocentesis performance. OBJECTIVE: To assess the success of emergency physicians performing landmark (LM) vs. ultrasound (US)-guided knee arthrocentesis techniques. METHODS: This was a prospective, randomized, controlled study of patients requiring knee arthrocentesis who presented to one urban university ED and two community EDs between June 2005 and February 2007. RESULTS: There were 66 patients enrolled (39 US-guided, 27 LM). Among all users, there was no difference in arthrocentesis success (US 37/39 vs. LM 25/27); p = 1.0. SECONDARY ENDPOINTS: 1) Patients reported less pain with ultrasound; US-guided 3.71 (95% confidence interval [CI] 2.61-4.80) cm vs. LM 5.19 (95% CI 3.94-6.45) cm; p = 0.02. 2) Providers felt the US-guided technique was easier to perform than LM; 1.67 units on 5-point scale (95% CI 1.37-1.97) vs. 2.11 (95% CI 1.79-2.42) units; p = 0.02. 3) The total procedure time was shorter with the US-guided technique; 10.58 (95% CI 7.36-13.80) min vs. LM 13.37 (95% CI 9.83-16.92) min; p = 0.05. 4) There was no difference in the amount of fluid obtained between techniques; US-guided 45.33 (95% CI 35.45-55.21) mL vs. LM 34.7 (95% CI 26.09-43.32) mL; p = 0.17. CONCLUSION: US-guided knee arthrocentesis technique does not improve overall success of obtaining joint fluid aspirate vs. the standard LM and palpation technique. An US-guided approach does not result in more pain for the patient, takes no additional time to perform and, at least for novice physicians, leads to more fluid aspiration and greater novice provider confidence with the procedure. Further studies with more participants and standardization of anesthetic quantity are required to validate these findings.

The effects of a commercially available weight loss program among obese patients with type 2 diabetes: a randomized study.

The purpose of this study was to assess the effects of a commercially available weight loss program on weight and glycemic control among obese patients with type 2 diabetes. Participants included 69 patients (49 females, 20 males) with type 2 diabetes who had a mean +/- SD age of 52.2 +/- 9.5 years, a body mass index of 39.0 +/- 6.2 kg/m(2), and hemoglobin A1c (HbA1c) of 7.5 +/- 1.6%. Over half (52.2%) of the participants were African American. Participants were randomly assigned to: 1) a portion-controlled diet (NutriSystem D) (PCD) or 2) a diabetes support and education (DSE) program. After the initial 3 months, the PCD group continued on the PCD for the remaining 3 months, and the DSE group crossed over to PCD for the remaining 3 months. The primary comparison for this study was at 3 months. At 3 months, the PCD group lost significantly more weight (7.1 +/- 4%) than the DSE group (0.4 +/- 2.3%) (P < 0.0001). From 3 to 6 months the change in weight for both groups was statistically significant. After 3 months, the PCD group had greater reductions in HbA1c than the DSE group (-0.88 +/- 1.1 vs 0.03 +/- 1.09; P < 0.001). From 3 to 6 months the PCD group had no further change in HbA1c, while the DSE group showed a significant reduction. These data suggest that obese patients with type 2 diabetes will experience significant improvements in weight, glycemic control, and cardiovascular disease risk factors after the use of a commercially available weight management program.

Traumatic, pericardio-diaphragmatic rupture: an extremely rare cause of pericarditis.

A 54-year-old man with a recent history of blunt abdominal trauma presented to the Emergency Department with severe pain in the chest and abdomen. He was tachycardic, tacypneic, and hypoxic. An electrocardiogram (EKG) at that time showed ST elevation and PR depression consistent with acute pericarditis, and a computed tomography (CT) scan subsequently showed herniation of abdominal contents into the pericardium and left hemithorax. After surgical repair of the diaphragmatic defect and intrapericardial hernia, the EKG findings resolved. He recovered over the course of several weeks and was subsequently discharged home.

An investigation of flumazenil to antagonize gamma-hydroxybutyrate intoxication in a murine model.

OBJECTIVE: Prior animal studies have suggested that flumazenil may blunt GHB's sedative-hypnotic affects. We hypothesized that flumazenil would decrease the affects of GHB in a murine model of intoxication. METHODS: We performed a controlled, pilot experiment using 32 mice divided into 3 groups. All mice received intraperitoneal injections of GHB (1.5 g/kg). Group I received sham injections at time 0, and then GHB at 5 minutes. Group II received flumazenil (0.3 mg/kg) at time 0, and then GHB at 5 minutes. Group III received sham injection at time 0, then GHB at 5 minutes, and then 4 escalating flumazenil doses administered at 3-minute intervals (0.003 to 1 mg/kg). We measured certain functions: time to loss/recovery of righting reflexes (RR), time to sprawl/recovery of sprawl (postural tone [PT]), and death. RESULTS: There were statistically significant delays in the loss of PT and shortened recovery time to RR in pre-treated mice (group II) versus controls (group I). There were no differences in group III versus group I for any outcome parameters. CONCLUSIONS: In this model, pre-dosing flumazenil prior to GHB administration delayed clinical intoxication.

Ultrasonography-guided peripheral intravenous access versus traditional approaches in patients with difficult intravenous access.

STUDY OBJECTIVE: We assess the success rate of emergency physicians in placing peripheral intravenous catheters in difficult-access patients who were unsuccessfully cannulated by emergency nurses. A technique using real-time ultrasonographic guidance by 2 physicians was compared with traditional approaches using palpation and landmark guidance. METHODS: This was a prospective, systematically allocated study of all patients requiring intravenous access who presented to 2 university hospitals between October 2003 and March 2004. Inclusion criterion was the inability of any available nurse to obtain intravenous access after at least 3 attempts on a subgroup of patients who had a history of difficult intravenous access because of obesity, history of intravenous drug abuse, or chronic medical problems. Exclusion criterion was the need for central venous access. Patients presenting on odd days were allocated to the ultrasonographic-guided group, and those presenting on even days were allocated to the traditional-approach group. Endpoints were successful cannulation, number of sticks, time, and patient satisfaction. RESULTS: Sixty patients were enrolled, 39 on odd days and 21 on even days. Success rate was greater for the ultrasonographic group (97%) versus control (33%), difference in proportions of 64% (95% confidence interval [CI] 39% to 71%). The ultrasonographic group required less overall time (13 minutes versus 30 minutes, for a difference of 17 [95% CI 0.8 to 25.6]), less time to successful cannulation from first percutaneous puncture (4 minutes versus 15 minutes, for a difference of 11 [95% CI 8.2 to 19.4]), and fewer percutaneous punctures (1.7 versus 3.7, for a difference of 2.0 [95% CI 1.27 to 2.82]) and had greater patient satisfaction (8.7 versus 5.7, for a difference of 3.0 [95% CI 1.82 to 4.29]) than the traditional landmark approach. CONCLUSION: Ultrasonographic-guided peripheral intravenous access is more successful than traditional "blind" techniques, requires less time, decreases the number of percutaneous punctures, and improves patient satisfaction in the subgroup of patients who have difficult intravenous access.

Aspiration of gastric contents: association with prehospital intubation.

We prospectively compared the incidence of pulmonary aspiration of gastric contents between patients endotracheally intubated in the prehospital (PH) setting and those intubated in the emergency department (ED). Tracheal aspirates were collected using a standard Leukens trap from all patients as soon as possible after endotracheal intubation. Tracheal aspirates were then tested for the presence of pepsin, a sensitive and specific marker of gastric contents, using a fibrinogen digestion technique. Over 8 months, 168 patients were enrolled. The pepsin assay was positive in 10 of 20 (50%) patients intubated in the PH group, as opposed to 33 of 148 (22%) of those intubated in the ED (chi2 P=.008; odds ratio, 3.5; 95% CI, 1.34-9.08). Patients endotracheally intubated in the PH setting are more likely to have aspirated gastric contents than those intubated in the ED.

Predictors of success in emergency medicine ultrasound education.

OBJECTIVES: To compare emergency medicine resident performance on an ultrasound-oriented, American Board of Emergency Medicine-styled written examination with the following variables in resident education: number of ultrasound scans performed, presence of a formal, structured ultrasound rotation, presence of a mandatory ultrasound rotation, number of hours of didactic ultrasound education, and percentage of ultrasound education taught by emergency physicians. METHODS: This was a prospective cohort study involving 14 residency programs. A 60-question multiple-choice test was completed by individual residents and returned for scoring. RESULTS: 262 residents completed the study. Average score was 39.1/60 +/- 6.5 (65%). Scores improved as residency year increased (year 1: 36.6, year 2: 39.3, year 3: 42.6) (p < 0.005). Scores improved as number of scans performed increased from 34.3 (57%) for those residents who had performed 0-10 scans to 45.4 (76%) for those with >150 scans (p < 0.005). The presence of an ultrasound rotation at an emergency medicine residency program also produced a statistically significant increase in test score (OR 1.82; 95% CI = 1.29 to 2.55). Residents at programs spending the least time (6 to 15 hours) on didactic education throughout the residency predicted examination failure (OR 0.60; 95% CI = 0.39 to 0.93). Increasing the amount of resident ultrasound teaching by emergency physicians improved the score, but this did not reach significance (p = 0.357). CONCLUSIONS: Improved resident performance on an ultrasound written examination was associated with increasing resident year, number of scans performed, and the presence of an ultrasound rotation at the residency program. Increasing the number of didactic hours spent on ultrasound each year beyond 15 hours showed no improvement in resident performance.
