Vaginal Swabs Are Non-inferior to Endocervical Swabs for Sexually Transmitted Infection testing in the Emergency Department.

STUDY OBJECTIVE: Emergency department (ED) testing for sexually transmitted infections (STI) in women is typically performed with a pelvic examination and an endocervical swab. However, vaginal swabs are effective for STI testing and the preferred specimen type according to the US Centers for Disease Control and Prevention. The utility of using vaginal swabs in the ED for STI screening has not been thoroughly investigated. Our objective was to assess detection rates for two bacterial STIs before and after implementing a screening protocol using vaginal swabs. METHODS: We conducted a quasi-experimental, pre-post study using standardized data from electronic health records across nine metropolitan Detroit hospital EDs. Patients included women who were tested for Chlamydia trachomatis or Neisseria gonorrhoeae in the ED between April 2018-December 2019. Pre-implementation tests from April 2018-February 2019 were done using endo-cervical swabs, and post-implementation tests from February 2019-December 2019 were done with vaginal swabs. We used non-inferiority testing for proportion with a non-inferiority margin of one percentage point absolute difference in detection rates of STI. RESULTS: The study included 22,291 encounters with 11,732 in the pre-implementation and 10,559 in the post-implementation phases. The C. trachomatis detection rates were 7.5% pre-implementation and 7.6% post-implementation (between-group difference, 0.1 percentage points; 95% confidence interval [CI]: -0.7, 0.4; p<.01 for non-inferiority). The N. gonorrhoeae detection rates were 3.1% pre-implementation and 3.6% post-implementation (between-group difference, 0.5 percentage points; 95% CI: -0.8, 0.04; p<.01 for non-inferiority). CONCLUSION: Using vaginal swabs for STI testing in the ED may be a non-inferior alternative to using endocervical swabs.

Hepatitis C Virus Reflex Testing Protocol in an Emergency Department.

INTRODUCTION: Our aim was to measure hepatitis C virus (HCV) screening and linkage-to-care rates in an urban emergency department (ED) before and after implementing an HCV viral RNA (vRNA) reflex testing protocol within a HCV screening program for at-risk patients. Our hypothesis was that using a reflex testing protocol would increase HCV testing rates of at-risk patients in the ED, which would increase the linkage-to-care rate. METHODS: In August 2018, our institution implemented an automated, electronic health record-based HCV screening protocol in the ED for at-risk patients. In January 2019, we implemented an HCV vRNA reflex testing protocol (reflex testing) for all positive HCV antibody (Ab) tests that were initiated through the screening protocol. We compared completion rates of HCV vRNA testing and the rate of linkage to care for patients with positive HCV Ab test results before and after implementation of reflex testing (five months per study period). RESULTS: Prior to reflex testing implementation, 233/425 (55%) patients with a positive HCV Ab test had an HCV vRNA test performed, whereas 270/323 (84%) patients with a positive HCV Ab test result had vRNA testing after reflex testing implementation (odds ratio [OR], 4.2; 95% confidence interval (CI): 3.0-6.0; P < 0.001). Of the eligible patients with positive HCV Ab test results who could be linked to care, 45 (10.6%) were linked to care before HCV reflex implementation and 46 (14.2%) were linked to care with reflex testing (OR, 1.4; 95% CI: 0.9-2.2; P = 0.13). CONCLUSION: Implementing a reflex testing initiative into an HCV screening program in the ED can result in an increase of the percentage of patients who receive an HCV vRNA test after having had a positive HCV Ab. Hepatitis C virus vRNA reflex testing was not associated with a statistically significant increase in linkage-to-care rates for HCV Ab-positive patients; however, further studies are required.

Systematic review and meta-analysis of effectiveness of treatment options against SARS-CoV-2 infection.

Treatment options for severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) are limited with no clarity on efficacy and safety profiles. We performed a systematic review and meta-analysis of studies on patients ≥18 years reporting data on therapeutic interventions in SARS-CoV-2. Primary outcome was all-cause mortality and secondary outcomes were rates of mechanical ventilation, viral clearance, adverse events, discharge, and progression to severe disease. Pooled rates and odds ratios (OR) were calculated. Twenty-nine studies with 5207 patients were included. Pooled all-cause mortality in intervention arm was 12.8% (95% confidence interval [CI]: 8.1%-17.4%). Mortality was significantly higher for studies using hydroxychloroquine (HCQ) for intervention (OR: 1.36; 95% CI: 0.97-1.89). Adverse events were also higher in HCQ subgroup (OR: 3.88; 95% CI: 1.60-9.45). There was no difference in other secondary outcomes. There is a need for well-designed randomized clinical trials for further investigation of every therapeutic intervention for further insight into different therapeutic options.

The mechanistic rationale of drugs, primary endpoints, geographical distribution of clinical trials against severe acute respiratory syndrome-related coronavirus-2: A systematic review.

There are numerous ongoing studies assessing treatment options for preventing, treating, and managing complications of coronavirus disease-2019 disease. The objective of this study was to do a systematic review and critical appraisal of the ongoing clinical trials with an aim to provide insight into the various interventions tested, clinical rationale, geographical distribution of the trials as well as the endpoints assessed in the studies. ClinicalTrials.gov, World Health Organization International Clinical Trials Registry Platform, and PubMed were assessed till 11 May 2020. The search resulted in 3242 ongoing studies of which 829 studies were included. There are 134 different drug-based interventions being assessed in 463 clinical trials as treatment options China accounts for 35% of all ongoing clinical studies followed by USA 23% and other countries together account for 42%. Amongst the 463 studies assessing drug-based treatment options, studies that are funded by federal and academic institutions are 79.6%, pharmaceutical company-funded studies are 15.11%, and no funding information is available in 5.10%. The definitive outcomes like mortality are being assessed as primary outcome in 22.8% of the studies only and need for ventilator in 6.2% of the studies. Amongst the pharmaceutical company-funded drug-based studies, only 20% of the studies had mortality as the primary outcome. Only 5.5% of the ongoing clinical trials are specifically designed to assess the most vulnerable population like elderly, patients with comorbidities and cancer. Multiple intervention-based clinical studies against severe acute respiratory syndrome-related coronavirus-2 are being performed throughout the world with a high concentration of clinical trials in the developed world with concern that of elderly and patients with comorbidities are being underrepresented and definite endpoints like mortality are being assessed in only one-fifth of the studies.

"They're Doing Their Job": Women's Acceptance of Emergency Department Contraception Counseling.

STUDY OBJECTIVE: We explore reproductive-aged women's acceptance of contraception counseling in the emergency department (ED). METHODS: This study is phase 1 of an exploratory sequential mixed methods study. We purposively interviewed 31 participants with the following criteria: black, white, or Latina race/ethnicity; nonpregnant; aged 15 to 44 years; receiving nonemergency care; not using highly effective contraception; and did not intend to become pregnant. We conducted semistructured interviews with a piloted interview guide until reaching thematic saturation. We coded transcripts with an iteratively developed codebook, maintaining intercoder agreement greater than 80%. Qualitative acceptance of ED contraception counseling was grouped into 3 categories: acceptable, unacceptable, and equivocal. We conducted a thematic text analysis to assess themes expressing support and concern for ED contraception counseling. Qualitative findings were stratified by age, race, and frequency of ED use. Using components of grounded theory, we developed a conceptual model. RESULTS: Most participants (81%) accepted ED contraception counseling. Themes expressing support and concern for ED contraception counseling included opportunity to address women's unmet contraception needs, contraception is within the scope of ED practice, the ED is a convenient setting with competent providers, contraception is a sensitive topic, and the ED may be an inappropriate setting for some women. Latina participants had lower acceptance of ED contraception counseling. Dominant subthemes varied slightly by race, age, and frequency of ED use. CONCLUSION: Diverse women had high acceptance of contraception counseling in the ED. Perspectives expressing both support and concern in regard to ED contraception counseling were explored in detail.

Community Health Workers in the Emergency Department-Can they Help with Chronic Hypertension Care.

PURPOSE OF REVIEW: To review community health worker (CHW) interventions tailored for hypertension management and to determine if the emergency department (ED) population would benefit from such interventions. RECENT FINDINGS: When working with patients who have one or more chronic diseases, CHW interventions have been very successful in improving health outcomes and are cost-effective. CHWs use a variety of techniques to address social determinants that patients may face that effect how they manage their chronic disease(s). Current CHW interventions in the ED have targeted the "super-user" population. CHW-based interventions help address social determinants of patients in a variety of settings, especially in the ED where the physicians have limited resources and time. There is limited information about how CHWs can improve community health outcomes outside of the ED "super-user" population. Future research needs to determine if creating a data-driven CHW intervention for the ED would be effective.

Emergency Department Discharge of Pulmonary Embolus Patients.

BACKGROUND: Hospitalization for low-risk pulmonary embolism (PE) is common, expensive, and of questionable benefit. OBJECTIVE: The objective was to determine if low-risk PE patients discharged from the emergency department (ED) on rivaroxaban require fewer hospital days compared to standard of care (SOC). METHODS: Multicenter, open-label randomized trial in low-risk PE defined by Hestia criteria. Adult subjects were randomized to early ED discharge on rivaroxaban or SOC. Primary outcome was total number of initial hospital hours, plus hours of hospitalization for bleeding or venous thromboembolism (VTE), 30 days after randomization. A 90-day composite safety endpoint was defined as major bleeding, clinically relevant nonmajor bleeding, and mortality. RESULTS: Of 114 randomized subjects, 51 were early discharge and 63 were SOC. Of 112 (98.2%) receiving at least one dose of study drug, 99 (86.8%) completed the study. Initial hospital LOS was 4.8 hours versus 33.6 hours, with a mean difference of -28.8 hours (95% confidence interval [CI] = -42.55 to -15.12 hours) for early discharge versus SOC, respectively. At 90 days, mean total hospital days (for any reason) were less for early discharge than SOC, 19.2 hours versus 43.2 hours, with a mean difference of 26.4 hours (95% CI = -46.97 to -3.34 hours). At 90 days, there were no bleeding events, recurrent VTE, or deaths. The composite safety endpoint was similar in both groups, with a difference in proportions of 0.005 (95% CI = -0.18 to 0.19). Total costs were $1,496 for early discharge and $4,234 for SOC, with a median difference of $2,496 (95% CI = -$2,999 to -$2,151). CONCLUSIONS: Low-risk ED PE patients receiving early discharge on rivaroxaban have similar outcomes to SOC, but fewer total hospital days and lower costs over 30 days.

Ventricular tachycardia cardiac arrest during central line placement.

Central venous catheterization is often necessary for the safe administration of medications that are caustic to peripheral veins, to place temporary transvenous pacemakers and to provide invasive hemodynamic monitoring in the critically ill. While a wide range of complications are known to occur with insertion of these catheters, there is a paucity of cases associated with cardiac arrest during the catheters placement. We describe an unusual case of sustained ventricular tachycardia and subsequent cardiac arrest that occurred during an ultrasound guided central venous catheter placement for a patient in septic shock. This case serves as a reminder of the rare, but potentially fatal complication of central venous access placement.

The incidence and significance of bacteremia in out of hospital cardiac arrest.

BACKGROUND: The most common etiology of cardiac arrest is presumed of myocardial origin. Recent retrospective studies indicate that preexisting pneumonia, a form of sepsis, is frequent in patients who decompensate with abrupt cardiac arrest without preceding signs of septic shock, respiratory failure or severe metabolic disorders shortly after hospitalization. The contribution of pre-existing infection on pre and post cardiac arrest events remains unknown and has not been studied in a prospective fashion. We sought to examine the incidence of pre-existing infection in out-of hospital cardiac arrest (OHCA) and assess characteristics associated with bacteremia, the goal standard for presence of infection. METHODS AND RESULTS: We prospectively observed 250 OHCA adult patients who presented to the Emergency Department (ED) between 2007 and 2009 to an urban academic teaching institution. Bacteremia was defined as one positive blood culture with non-skin flora bacteria or two positive blood cultures with skin flora bacteria. 77 met pre-defined exclusion criteria. Of the 173 OHCA adults, 65 (38%) were found to be bacteremic with asystole and PEA as the most common presenting rhythms. Mortality in the ED was significantly higher in bacteremic OHCA (75.4%) compared to non-bacteremic OHCA (60.2%, p<0.05). After adjustment for potential confounders, predictive factors associated with bacteremic OHCA were lower initial arterial pH, higher lactate, WBC, BUN and creatinine. CONCLUSIONS: Over one-third of OHCA adults were bacteremic upon presentation. These patients have greater hemodynamic instability and significantly increased short-term mortality. Further studies are warranted to address the epidemiology of infection as possible cause of cardiac arrest.

Unusual presentation of toxoplasma gondii encephalitis.

We report a case of altered mental status secondary to acute Toxoplasma Gondii encephalitis. The patient had no medical or surgical history and presented with acute onset of lethargy with no clear precipitant. A physical exam revealed no focal neurological deficits and a subsequent medical workup revealed multiple intracranial lesions with a biopsy confirming the diagnosis of Toxoplasma Gondii encephalitis in the setting of newly diagnosed human immunodeficiency virus (HIV). A literature review revealed that this is a unique case of toxoplasmic encephalopathy in the United States in a previously undiagnosed HIV positive patient presenting to an emergency department.

Use of antiemetics in children with acute gastroenteritis: Are they safe and effective?

The use of antiemetics is a controversial topic in treatment of pediatric gastroenteritis. Although not recommended by the American Academy of Pediatrics, antiemetics are commonly prescribed by physicians. A review of the literature shows side effects of promethazine, prochlorperazine, and metoclopramide are common and potentially dangerous. Ondansetron has recently been studied as an adjunct to oral rehydration therapy in treatment of acute gastroenteritis with mild to moderate dehydration. Although studies are limited, early research suggests the medication is safe when used in a single dose and can be effective to prevent vomiting, the need for intravenous fluids, and hospital admission.
