A Novel Risk Score to Guide the Evaluation of Acute Hematogenous Osteomyelitis in Children.

OBJECTIVES: To identify independent predictors of and derive a risk score for acute hematogenous osteomyelitis (AHO) in children. METHODS: We conducted a retrospective matched case-control study of children >90 days to <18 years of age undergoing evaluation for a suspected musculoskeletal (MSK) infection from 2017 to 2019 at 23 pediatric emergency departments (EDs) affiliated with the Pediatric Emergency Medicine Collaborative Research Committee. Cases were identified by diagnosis codes and confirmed by chart review to meet accepted diagnostic criteria for AHO. Controls included patients who underwent laboratory and imaging tests to evaluate for a suspected MSK infection and received an alternate final diagnosis. RESULTS: We identified 1135 cases of AHO matched to 2270 controls. Multivariable logistic regression identified 10 clinical and laboratory factors independently associated with AHO. We derived a 4-point risk score for AHO using (1) duration of illness >3 days, (2) history of fever or highest ED temperature ≥38°C, (3) C-reactive protein >2.0 mg/dL, and (4) erythrocyte sedimentation rate >25 mm per hour (area under the curve: 0.892, 95% confidence interval [CI]: 0.881 to 0.901). Choosing to pursue definitive diagnostics for AHO when 3 or more factors are present maximizes diagnostic accuracy at 84% (95% CI: 82% to 85%), whereas children with 0 factors present are highly unlikely to have AHO (sensitivity: 0.99, 95% CI: 0.98 to 1.00). CONCLUSIONS: We identified 10 predictors for AHO in children undergoing evaluation for a suspected MSK infection in the pediatric ED and derived a novel 4-point risk score to guide clinical decision-making.

Simulation as a Dynamic Tool to Reorganize Pediatric Emergency Department Resuscitation During the Coronavirus Disease 2019 Pandemic and Beyond.

BACKGROUND: The coronavirus disease 2019 pandemic has challenged hospitals and pediatric emergency department (PED) providers to rapidly adjust numerous facets of the care of critically ill or injured children to minimize health care worker (HCW) exposure to severe acute respiratory syndrome coronavirus 2. OBJECTIVE: We aimed to iteratively devise protocols and processes that minimized HCW exposure while safely and effectively caring for children who may require unanticipated aerosol-generating procedures. METHODS: As part of our PED's initiative to optimize clinical care and HCW safety during the coronavirus disease 2019 pandemic, regular multidisciplinary systems and process simulation sessions were conducted. These sessions allowed us to evaluate and reorganize patient flow, test and improve communication modalities, alter the process for consultation in resuscitations, and teach and reinforce the appropriate donning and use of personal protective equipment. RESULTS: Simulation was a highly effective method to disseminate new practices to PED staff. Numerous workflow modifications were implemented as a result of our in situ systems and process simulations. Total number of persons in the resuscitation room was minimized, use of a "command post" with remote providers was initiated, communication devices and strategies were trialed and adopted, and personal protective equipment standards that optimized HCW safety and communication were enacted. CONCLUSIONS: Simulation can be an effective and agile tool in restructuring patient workflow and care of the most critically ill or injured patients in a PED during a novel pandemic.

Accuracy of automated identification of delayed diagnosis of pediatric appendicitis and sepsis in the ED.

BACKGROUND: Delayed diagnoses of serious emergency conditions can lead to morbidity in children, but are challenging to identify and measure. We developed and piloted an automated tool for identifying delayed diagnosis of two serious conditions commonly seen in the ED using administrative data. METHODS: We identified cases with a final diagnosis of appendicitis or sepsis in a freestanding children's hospital from 2008 to 2018, with any hospital ED encounter within the preceding 7 days. Two investigators reviewed a subset of these cases using the electronic health records (EHR) to determine if there was a delayed diagnosis and interrater reliability was assessed using the intraclass correlation coefficient (ICC). An automated tool was applied to the same cases to assess its positive predictive value (PPV) to identify those with a delayed diagnosis, using the manual chart review as the gold standard. The tool used number of days since visit, presence of a related diagnosis on the initial visit, and whether or not the patient was discharged. RESULTS: Previous ED encounters preceded 91/3703 (2.5%) appendicitis cases and 159/1754 (9.1%) sepsis cases; 78 cases of each were sampled for review. In manual review, 73.4% and 22.8% were thought to have delayed diagnoses; reviewer agreement was excellent (appendicitis ICC 0.77, 95% CI 0.62 to 0.86 and sepsis ICC 0.77, 95% CI 0.43 to 0.89). The PPVs of the automated tool for determination of delayed diagnosis for appendicitis within 1, 3 or 7 days were 96.2%, 95.1% and 93.6%, respectively. For sepsis, the PPVs were 71.4%, 63.6% and 41.2% within 1, 3 or 7 days, respectively. CONCLUSIONS: This automated tool performed well compared with expert EHR review. Performance was stronger for appendicitis. Further tool refinement could improve performance.

Palliative Care Consultation and Associated End-of-Life Care After Pacemaker or Implantable Cardioverter-Defibrillator Deactivation.

The presence of cardiac pacemakers and defibrillators complicates making end-of-life (EOL) medical decisions. Palliative care/medicine consultation (PCMC) may benefit patients and primary providers, but data are lacking. We retrospectively reviewed 150 charts of patients who underwent device deactivation at our tertiary care center (between November 1, 2008, and September 1, 2012), assessing for PCMC and outcomes. Overall, 42% of patients received a PCMC, and 68% of those PCMCs specifically addressed device deactivation. Median survival following deactivation was 2 days, with 42% of deaths occurring within 1 day of deactivation. There was no difference in survival between the groups. The EOL care for patients with implanted cardiac devices is complex, but PCMC may assist with symptom management and clarification of goals of care for such patients.

Features and outcomes of patients who underwent cardiac device deactivation.

IMPORTANCE: Little is known about patients who undergo cardiovascular implantable electronic device deactivation. OBJECTIVE: To describe features and outcomes of patients who underwent cardiovascular implantable electronic device deactivation. DESIGN, SETTING, AND PARTICIPANTS: Retrospective review of medical records of 150 patients at a tertiary academic medical center (Mayo Clinic, Rochester, Minnesota). EXPOSURE Cardiovascular implantable electronic device deactivation. MAIN OUTCOMES AND MEASURES: Demographic and clinical data and information regarding advance directives, ethics consultations, palliative medicine consultations, and cardiovascular implantable electronic device deactivations. RESULTS: Of the 150 patients (median age, 79 years; 67% were male), 149 (99%) had poor or terminal prognoses. Overall, 118 patients (79%) underwent deactivation of tachycardia therapies only, and 32 (21%) underwent deactivation of bradycardia therapies with or without tachycardia therapies (6 patients [4%] were pacemaker-dependent). Half of the deactivation requests (51%) were made by surrogates. A majority of deactivations (55%) were carried out by nurses. Although 85 patients (57%) had advance directives, only 1 mentioned the device in the directive. Ethics consultations occurred in 3 patients (2%) and palliative medicine consultations in 64 (43%). The proportions of patients who died within 1 month of device deactivation were similar for those who underwent deactivation of tachycardia therapies only and those who underwent deactivation of bradycardia therapies with or without tachycardia therapies (85% vs 94%; P = .37). CONCLUSIONS AND RELEVANCE: Most requests for cardiovascular implantable electronic device deactivation were for implantable cardioverter-defibrillator-delivered tachycardia therapies only. Many of these requests were made by surrogates. Advance directives executed by patients with these devices rarely addressed device management. Regardless of device therapy, most patients died shortly after device deactivation. Hence, a device deactivation decision may reflect the seriousness of a given patient's underlying illness. Patients with devices should engage in advance care planning to ensure that future care is consistent with their preferences.

Clostridium septicum brain abscesses in a premature neonate.

Brain abscesses in neonates are typically caused by Gram-negative organisms. There are no previously described cases caused by Clostridium septicum. We present a case of a premature male infant who developed recurrent episodes of suspected necrotizing enterocolitis followed by brain abscesses, cerebritis and ventriculitis caused by C. septicum.
