Comparison of Length of Stay Between Children Admitted to an Observation Versus Inpatient Unit.

OBJECTIVES: Many children who require hospitalization are ideal candidates for care in pediatric observation units (POUs) rather than inpatient pediatric units. Differences in outcomes between children cared for in these 2 practice settings have not been thoroughly evaluated. METHODS: In this retrospective cohort study, children aged 0 to 18 years admitted to a POU at a community hospital or inpatient unit at a children's hospital were enrolled if they met specific clinical criteria. Information regarding the current illness, medical history, and hospital course was collected. Hospital length of stay (LOS) was analyzed as the primary outcome; secondary outcomes included conversion to inpatient care for the POU group and return to pediatric emergency department within 7 days. Subgroup analysis was conducted on children presenting with respiratory illnesses. Propensity scores were used as a predictor in the final model. RESULTS: One hundred eighty-one admissions, 92 to POU and 89 to an inpatient unit, were analyzed. Mean LOS was 24.4 hours (95% confidence interval [CI], 21.7-27.1) for observation and 43.2 hours (95% CI, 37.8-48.6) for inpatient (P < 0.01). Among the 126 children admitted for respiratory illnesses, the mean LOS was 32.3 hours (95% CI, 26.0-38.6) for observation and 48.1 hours (95% CI, 42.2-54.0) for inpatient (P < 0.01). Survival analysis demonstrated a 1.61 (95% CI, 1.07-2.42) fold shorter time to discharge among children admitted to observation compared with inpatient (P = 0.02) and a 1.70 (95% CI, 1.07-2.71) fold shorter time to discharge from observation compared with inpatient for respiratory illnesses (P = 0.03). Within 7 days of discharge, 2 (2%) patients from the observation group and 1 (1%) from the inpatient group returned to the pediatric emergency department. CONCLUSIONS: These findings suggest that POU may provide the means toward efficient care for children in community settings with illnesses requiring brief hospitalizations. Future work including prospective investigations is needed to ascertain the generalizability of these findings.

Relationship of hepatitis C risk to hepatitis C test acceptance among adult patients participating in an ED hepatitis C screening programme.

BACKGROUND: It is possible that adult ED patients consider their hepatitis C virus (HCV) risk factor history when deciding whether to accept HCV screening. To help address this question, we examined whether self-reporting any HCV risk was more common among ED patients who agreed than who declined HCV screening. Among ED patients who agreed to HCV screening, we also assessed if self-reporting any HCV risk was more common among those whose HCV antibody (Ab) and HCV viral load (VL) test results were positive. METHODS: This study was conducted among adult patients ≥18 years old participating in a universal, ED-based HCV screening programme in New York City between 22 January 2019 and 9 April 2020. Participants were surveyed about their HCV risk factors. Differences in the frequencies of self-reporting any HCV risk were compared according to HCV screening acceptance and by HCV Ab and VL status. RESULTS: Of the 4658 ED patients surveyed, 2846 (61%) accepted and 1812 (39%) declined HCV screening. Among these participants, 38% reported at least one HCV risk factor, most commonly injection drug use. Self-reporting any HCV risk was not more common among those who accepted versus declined HCV screening (40% vs 37%, p<0.7) but was more common among those with HCV Ab positive versus negative test results (36% vs 6%, p<0.001) and HCV VL positive versus negative results (95% vs 5%, p<0.001). CONCLUSION: HCV risk factors were self-reported by more than one-third of ED patients but were not more commonly present among those who accepted HCV screening.

Evaluation and validation of an RT-PCR assay for specific detection of monkeypox virus (MPXV).

Monkeypox virus (MPXV) is a zoonotic orthopoxvirus within the Poxviridae family. MPXV is endemic to Central and West Africa. However, the world is currently witnessing an international outbreak with no clear epidemiological links to travel or animal exposure and with ever-increasing numbers of reported cases worldwide. Here, we evaluated and validated a new, sensitive, and specific real-time PCR-assay for MPXV diagnosis in humans and compare the performance of this novel assay against a Food & Drug Administration-cleared pan-Orthopox RT-PCR assay. We determined specificity, sensitivity, and analytic performance of the PKamp™ Monkeypox Virus RT-PCR assay targeting the viral F3L-gene. In addition, we further evaluated MPXV-PCR-positive specimens by viral culture, electron microscopy, and viral inactivation assays. The limit of detection was established at 7.2 genome copies/reaction, and MPXV was successfully identified in 20 clinical specimens with 100% correlation against the reference method with 100% sensitivity and specificity. Our results demonstrated the validity of this rapid, robust, and reliable RT-PCR assay for specific and accurate diagnosis of MPXV infection in human specimens collected both as dry swabs and in viral transport media. This assay has been approved by NYS Department of Health for clinical use.

Nontargeted Hepatitis C Screening in an Urban Emergency Department in New York City.

BACKGROUND: Previously the Centers for Disease Control and Prevention (CDC) recommended targeted hepatitis C virus (HCV) screening for adults born between 1945 and 1965 and individuals with HCV risk factors. In April 2020, the CDC updated their recommendations to now include all individuals 18 years of age and older in settings with HCV prevalence > 0.1%. Few emergency departments (EDs) currently employ this nontargeted screening approach. OBJECTIVES: We examined how a shift from targeted to nontargeted screening might affect HCV case identification. We hypothesized that nontargeted screening could improve HCV case identification in our ED. METHODS: Retrospective review of prospectively collected nontargeted screening data from June 6, 2018 to June 5, 2019 in a large urban academic ED. Patients 18 years of age and older, triaged to the adult or pediatric ED and able to provide consent for HCV testing, were eligible for study inclusion. RESULTS: There were 83,864 ED visits and 40,282 unique patients deemed eligible for HCV testing. Testing occurred in 10,630 (26.4%) patients, of which 638 (6%) had positive HCV antibody (Ab+) tests and 214 (2%) had a positive viral load (VL+). Birth cohort-targeted screening would have identified 48% of the patients with Ab+ tests and 47% of those who were VL+. Risk-based targeted screening would increase the number of Ab+ patients to 67% and VL+ to 72%. CONCLUSIONS: Nontargeted ED-based HCV screening can identify a large number of patients with HCV infection. A shift from targeted to nontargeted screening may result in fewer missed infections but requires further study.

Antibiotic prescribing patterns for adult urinary tract infections within emergency department and urgent care settings.

Urinary tract infections (UTI) are a common reason for emergency department (ED) and urgent care (UC) visits. Fluoroquinolones (FQ) are frequently prescribed for treatment of UTI in the outpatient setting; however, data evaluating prescribing patterns after FDA safety warnings is limited, especially in UC. The study goal was to investigate and compare antimicrobial prescribing for UTIs in a single-site ED and an off-site UC in an urban, academic health system. This retrospective study included patients presenting with a UTI to the ED or UC between January and June 2018. Those 18 years or older with uncomplicated, complicated UTI, or pyelonephritis were included. Exclusion criteria were catheter-related UTI, urinary tract abnormalities, immunocompromised, or hospitalization. Primary outcome was FQ prescribing rate for all UTI in the ED and UC. Secondary outcomes were rates of non-FQ prescribing, re-presentation, bug-drug mismatch, and treatment durations. 184 patients were included. FQ prescribing rate was similar in ED and UC (21.2% vs. 16.3%, p = 0.4). Non-FQs prescribed in ED and UC were nitrofurantoin (20.2% vs 53.6%), beta-lactams (46.1% vs 22.6%), and trimethoprim/sulfamethoxazole (12.5% vs. 5%). A longer than recommended duration was identified in 46.3% UC patients compared to 21.2% ED patients. Thirty-day re-presentation with persistent UTI symptoms occurred more frequently in the ED compared to UC (13.5% vs. 7.5%). Predictors of FQ prescribing on logistic regression were male, recurrent UTI, and malignancy. FQ prescribing rate for UTI treatment was low with no difference between ED and UC. Opportunity exists to improve treatment duration and antimicrobial choice.

Sepsis Bundle Adherence Is Associated with Improved Survival in Severe Sepsis or Septic Shock.

INTRODUCTION: There have been conflicting data regarding the relationship between sepsis-bundle adherence and mortality. Moreover, little is known about how this relationship may be moderated by the anatomic source of infection or the location of sepsis declaration. METHODS: This was a multi-center, retrospective, observational study of adult patients with a hospital discharge diagnosis of severe sepsis or septic shock. The study included patients who presented to one of three Los Angeles County Department of Health Services (DHS) full-service hospitals January 2012 to December 2014. The primary outcome of interest was the association between sepsis-bundle adherence and in-hospital mortality. Secondary outcome measures included in-hospital mortality by source of infection, and the location of sepsis declaration. RESULTS: Among the 4,582 patients identified with sepsis, overall mortality was lower among those who received bundle-adherent care compared to those who did not (17.9% vs. 20.4%; p=0.035). Seventy-five percent (n=3,459) of patients first met sepsis criteria in the ED, 9.6% (n=444) in the intensive care unit (ICU) and 14.8% (n=678) on the ward. Bundle adherence was associated with lower mortality for those declaring in the ICU (23.0% adherent [95% confidence interval{CI} {16.8-30.5}] vs. 31.4% non-adherent [95% CI {26.4-37.0}]; p=0.063), but not for those declaring in the ED (17.2% adherent [95% CI {15.8-18.7}] vs. 15.1% non-adherent [95% CI {13.0-17.5}]; p=0.133) or on the ward (24.8% adherent [95% CI {18.6-32.4}] vs. 24.4% non-adherent [95% CI {20.9-28.3}]; p=0.908). Pneumonia was the most common source of sepsis (32.6%), and patients with pneumonia had the highest mortality of all other subsets receiving bundle non-adherent care (28.9%; 95% CI [25.3-32.9]). Although overall mortality was lower among those who received bundle-adherent care compared to those who did not, when divided into subgroups by suspected source of infection, a statistically significant mortality benefit to bundle-adherent sepsis care was only seen in patients with pneumonia. CONCLUSION: In a large public healthcare system, adherence with severe sepsis/septic shock management bundles was found to be associated with improved survival. Bundle adherence seems to be most beneficial for patients with pneumonia. The overall improved survival in patients who received bundle-adherent care was driven by patients declaring in the ICU. Adherence was not associated with lower mortality in the large subset of patients who declared in the ED, nor in the smaller subset of patients who declared in the ward.

The Effect of Utilization Review on Emergency Department Operations.

STUDY OBJECTIVE: Increasingly, hospitals are using utilization review software to reduce hospital admissions in an effort to contain costs. Such practices have the potential to increase the number of unsafe discharges, particularly in public safety-net hospitals. Utilization review software tools are not well studied with regard to their effect on emergency department (ED) operations. We study the effect of prospectively used admission decision support on ED operations. METHODS: In 2012, Los Angeles County + University of Southern California Medical Center implemented prospective use of computerized admission criteria. After implementation, only ED patients meeting primary review (diagnosis-based criteria) or secondary review (medical necessity as determined by an on-site emergency physician) were assigned inpatient beds. Data were extracted from electronic medical records from September 2011 through December 2013. Outcomes included operational metrics, 30-day ED revisits, and 30-day admission rates. Excluding a 6-month implementation period, monthly summary metrics were compared pre- and postimplementation with nonparametric and negative binomial regression methods. All adult ED visits, excluding incarcerated and purely behavioral health visits, were analyzed. The primary outcomes were disposition rates. Secondary outcomes were 30-day ED revisits, 30-day admission rate among return visitors to the ED, and estimated cost. RESULTS: Analysis of 245,662 ED encounters was performed. The inpatient admission rate decreased from 14.2% to 12.8%. Increases in discharge rate (82.4% to 83.4%) and ED observation unit utilization (2.5% to 3.4%) were found. Thirty-day revisits increased (20.4% to 24.4%), although the 30-day admission rate decreased (3.2% to 2.8%). Estimated cost savings totaled $193.17 per ED visit. CONCLUSION: The prospective application of utilization review software in the ED led to a decrease in the admission rate. This was tempered by a concomitant increase in ED observation unit utilization and 30-day ED revisits. Cost savings suggest that resources should be redirected to the more highly affected ED and ED observation unit, although more work is needed to confirm the generalizability of these findings.

Reduction in Jail Emergency Department Visits and Closure After Implementation of On-Site Urgent Care.

This descriptive study evaluates the impact of implementation of full service on-site urgent care services at the Los Angeles County Jail (LACJ) by examining the number of patients seen at the referral hospital, Los Angeles County + University of Southern California Medical Center (LAC+USC), and the number of hours that the referral hospital was closed to transfers in the periods before and after the development of the LACJ Urgent Care. The appropriate utilization of public resources is a critical priority for an overburdened county medical health care system. Implementing on-site urgent care staffed by emergency physicians led to reductions in the average number of patients transferred to LAC+USC, the average number of monthly closure hours, and the average days per month when closure to transfer occurred, and a cost savings of some $2 million, primarily in personnel costs.
