A Tale of 102,726 Messages: Characterizing the Modern Urologist's Portal Message Burden After Common Urologic Surgeries.

We aimed to characterize patient portal messaging use after urologic surgery to identify administrative burden and evaluate postoperative clinical associations. Epic was queried for all urologic surgeries performed at the Mayo Clinic enterprise between 2019 and 2022. Data from the highest volume procedures were extracted including patient-generated portal messages to their provider and emergency department (ED) visits within 6 months of surgery. Factors associated with portal users and message volume, as well as the impact of portal use on risk of subsequent ED visit, were evaluated. We analyzed data from 23,621 urologic procedures, which generated 102,726 patient portal messages within 6 months of surgery. We found that 55% of our cohort sent at least 1 message. Stratifying by subspecialty, endourologic surgeries generated the fewest number of messages per surgery (3.83; SD, 8.76), whereas female pelvic medicine and reconstructive surgeries yielded the most (6.05; SD, 10.92). Younger age, female sex, and White race were associated with increased portal utilization. Multivariable time-to-event analysis revealed a 33% reduction in the risk of ED presentation within 90 days after surgery for patients using the patient portal compared with those who did not. While only half of patients sent portal messages after surgery, active users showed a 33% reduction in ED visits, suggesting its potential to reduce health care utilization. Encouraging broader portal adoption can improve outcomes. However, the message burden for urologists necessitates solutions. Resource allocation should prioritize strategies to help urologists manage messages while preserving the established clinical benefits.

Association between telehealth use in oncology and downstream utilization at a large academic health system.

While telemedicine has been beneficial in oncology by reducing infectious exposure and improving access for patients with poor functional status, it also has intrinsic limitations, including the inability to perform a physical exam, which could lead to increased downstream utilization in this population at high risk of medical decompensation. We conducted a retrospective cohort study investigating the relationship between telemedicine use in oncology and subsequent outpatient oncology encounters, emergency department (ED) visits, and hospitalizations. We included outpatient oncology encounters, including telemedicine and in-person visits, occurring between 1 January 2018 and 31 December 2022 at a large academic health system. Unadjusted descriptive statistics and multiple linear regressions were used to estimate subsequent outpatient oncology visits, ED visits, and hospitalizations within 30 days of an index visit based on modality (telemedicine versus in-person). The multiple regressions were adjusted for various demographic and clinical characteristics, including palliative care visits, baseline utilization, recent chemotherapy, and comorbidities. Our cohort included 63,722 patients with 689,356 outpatient encounters, of which 639,217 (92.7%) were in-person and 50,139 (7.3%) were telemedicine visits. Patients on average had 0.91 outpatient oncology visits, 0.04 ED visits, and 0.05 hospitalizations within 30 days following an index encounter. In our adjusted analyses, telemedicine was associated with 13.7 fewer downstream outpatient oncology visits (95% CI 12.5-14.9; p < 0.001) per 100 index encounters, 0.7 fewer ED visits (95% CI 0.4-1.0; p < 0.001) per 100 index encounters and 0.9 fewer hospitalizations (95% CI 0.6-1.3; p < 0.001) per 100 index encounters compared to in-person visits. Contrary to our hypothesis, oncology patients who had a telemedicine visit had fewer follow-up outpatient oncology encounters, ED visits and hospitalizations after 30 days than those with in-person visits. Future studies should further investigate the efficacy of telemedicine in oncology and outline specific scenarios for appropriate use in this and other populations.

"Before medically advised" departure from hospital and subsequent drug overdose: a population-based cohort study.

A substantial number of hospital admissions end in patient-initiated departure before medical treatment is complete. Whether "before medically advised" (BMA) discharge increases the risk of subsequent drug overdose remains uncertain. We performed a retrospective cohort study using administrative health data from a 20% random sample of residents of British Columbia, Canada. We focused on nonelective, nonobstetric hospital stays occurring between 2015 and 2019. We used survival analysis to compare the rate of fatal or nonfatal illicit drug overdose in the first 30 days after BMA discharge versus the rate after physician-advised discharge. Overall, 6440 of 189 808 (3.4%) hospital stays ended in BMA discharge. Among 820 overdoses occurring in the first 30 days after any hospital discharge, 755 (92%) involved patients with a history of substance use disorder. Unadjusted overdose rates were 10-fold higher after BMA discharge than after physician-advised discharge, and BMA discharge was associated with subsequent overdose even after adjustment for potential confounders (crude incidence, 2.8% v. 0.3%; adjusted hazard ratio [HR] 1.58; 95% confidence interval [CI] 1.31-1.89). Before medically advised discharge was associated with increases in subsequent emergency department visits (adjusted HR 1.92; 95% CI 1.83-2.02) and unplanned hospital readmissions (adjusted HR 2.07; 95% CI 1.96-2.19), but there was no significant association with the uncommon outcomes of fatal overdose and all-cause mortality. Before medically advised departure is associated with an increased risk of drug overdose in the first 30 days after discharge. Improved treatment of substance use disorder, expanded access to overdose prevention services, and new means of postdeparture outreach should be explored to reduce this risk.

Thresholds in PROMIS Scores Anchored to Subsequent Unscheduled Health Service Use Among People Diagnosed With Cancer.

To establish thresholds in the Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference, physical function, fatigue, and depression scores on the basis of their association with subsequent use of the emergency department (ED) or urgent care by people diagnosed with cancer. Retrospective data from 952 people seen at Henry Ford Cancer and insured through the Health Alliance Plan were analyzed using generalized linear mixed-effects models. The log odds of ED or urgent care use during 14 or 30 days after each patient-reported outcome (PRO) assessment were related to PRO scores, while adjusting for comorbidity, sociodemographic, and tumor characteristics. Pain interference and physical function were associated with subsequent ED or urgent care visits, but fatigue and depression were not, and the results for 14- and 30-day visits were similar. Thresholds anchored in the likelihood of these visits differed according to cancer stage. For people with advanced cancer, a pain interference score of 60 or higher (odds ratio [OR] 3.75, [95% CI, 1.53 to 7.87]) and a physical function score lower than 40 (OR 2.94, [95% CI, 1.22 to 7.06]) produced the largest ORs with narrowest CIs for 30-day visits. For people with nonadvanced cancer, the thresholds of 65 for pain interference (OR 2.64, [95% CI, 1.40 to 5.01]) and 35 for physical function (OR 1.87, [95% CI, 1.01 to 3.45]) produced largest ORs with narrowest CIs for 30-day visits. These anchor-based thresholds in PROMIS scores can inform clinicians' actions with the goal of preventing ED or urgent care visits.

Changes in interpersonal violence and utilization of trauma recovery services at an urban trauma center in the United States during the COVID-19 pandemic: a retrospective, comparative study.

This study investigated changes in interpersonal violence and utilization of trauma recovery services during the COVID-19 pandemic. At an urban level I trauma center, trauma recovery services (TRS) provide education, counseling, peer support, and coordination of rehabilitation and recovery to address social and mental health needs. The COVID-19 pandemic prompted considerable changes in hospital services and increases in interpersonal victimization. A retrospective analysis was conducted between September 6, 2018 and December 20, 2020 for 1,908 victim-of-crime patients, including 574 victims of interpersonal violence. Outcomes included length of stay associated with initial TRS presentation, number of subsequent emergency department visits, number of outpatient appointments, and utilization of specific specialties within the year following the initial traumatic event. Patients were primarily female (59.4%), single (80.1%), non-Hispanic (86.7%), and Black (59.2%). The mean age was 33.0 years, and 247 patients (49.2%) presented due to physical assault, 132 (26.3%) due to gunshot wounds, and 76 (15.1%) due to sexual assault. The perpetrators were primarily partners (27.9%) or strangers (23.3%). During the study period, 266 patients (mean, 14.9 patients per month) presented before the declaration of COVID-19 as a national emergency on March 13, 2020, while 236 patients (mean, 25.9 patients per month) presented afterward, representing a 74.6% increase in victim-of-crime patients treated. Interactions with TRS decreased during the COVID-19 period, with an average of 3.0 interactions per patient before COVID-19 versus 1.9 after emergency declaration (P<0.01). Similarly, reductions in length of stay were noted; the pre-COVID-19 average was 3.6 days, compared to 2.1 days post-COVID-19 (P=0.01). While interpersonal violence increased, TRS interactions decreased during the COVID-19 pandemic, reflecting interruption of services, COVID-19 precautions, and postponement/cancellation of elective visits. Future direction of hospital policy to enable resource and service delivery to this population, despite internal and external challenges, appears warranted.

Factors Contributing to the Recurrence of Urinary Tract Infections and Revisit amongst Children in the Emergency Department: A Single-Centre Retrospective Study.

Urinary tract infections (UTIs) are prevalent amongst paediatric patients, and they can lead to emergency department (ED) visits. A subset of patients requires a second ED visit, creating a burden on healthcare resources. This study aimed to shed light on the clinical, laboratory, treatment-related and environmental determinants associated with the recurrence of ED visits in this specific paediatric population. This single-centre retrospective study involved paediatric patients diagnosed with UTIs and admitted to the paediatric ED of our hospital from September 2021, to August 2023. In accordance with whether a second visit was required, the ED patients were grouped into non-second-visit group or second-visit group. The demographic, clinical, laboratory, diagnostic, and environmental factors were analysed in detail. Statistical analyses, including chi-square tests, t-tests and correlation analyses, were employed to assess the associations between various factors and subsequent ED visits. A total of 357 patients, including 324 patients without a second visit and 33 patients with a second visit, were included in this study. Factors significantly associated with second ED visits included fever (≥38.5 °C) at initial presentation (p = 0.034), longer symptom duration (p = 0.022), increased C-reactive protein (CRP) levels (p = 0.018), hydronephrosis (p = 0.033) and lack of oral antibiotic use before the first visit (45.45% vs. 67.9%, p = 0.017). More bubble bath exposure (p = 0.037) and lower consultation rates with paediatric urology services (p = 0.020) were associated with repeated visits. Multifactor logistic regression analysis showed that the factors significantly associated with second ED visits were longer symptoms duration, fever (≥38.5 °C) at initial presentation, presence of flank pain, increased CRP levels, hydronephrosis, renal stones, vesicoureteral reflux, underlying anatomical abnormalities, lack of oral antibiotic use before the first visit, bubble bath exposure and lower consultation rates with paediatric urology services. A series of clinical indicators, laboratory findings, diagnostic measures and environmental factors may be associated with the need for a second ED visit amongst paediatric patients with UTI. Early antibiotic intervention, identification of underlying anatomical anomalies and management of environmental exposures may mitigate recurrent ED visits.

Hospital Encounters Within 1 Year Postpartum Across Insurance Types, Oregon 2012-2017.

Little is known about the timing and frequency of postpartum hospital encounters and postpartum visit attendance and how they may be associated with insurance types. Research on health insurance and its association with postpartum care utilization is often limited to the first 6 weeks. To assess whether postpartum utilization (hospital encounters within 1 year postpartum and postpartum visit attendance within 12 weeks) differs by insurance type at birth (Medicaid, high deductible health plans, and other commercial plans) and whether rates of hospital encounters differ by postpartum visit attendance and insurance status. Time-to-event analysis of Oregon hospital births from 2012 to 2017 using All Payer All Claims data. We conducted weighted Cox Proportional Hazard regressions and accounted for differences in insurance type at birth using multinomial propensity scores. Among 202,167 hospital births, 24.9% of births had at least 1 hospital encounter within 1 year postpartum. Births funded by Medicaid had a higher risk of a postpartum emergency department (ED) visit (hazard ratio: 2.05, 95% CI: 1.99, 2.12) and lower postpartum visit attendance (hazard ratio: 0.71, 95% CI: 0.70, 0.72) compared with commercial plans. Among Medicaid beneficiaries, missing the postpartum visit in the first 6 weeks was associated with a lower risk of subsequent readmissions (adjusted hazard ratio 0.77, 95% CI: 0.68, 0.87) and ED visits (adjusted hazard ratio: 0.87 (0.85, 0.88). Medicaid beneficiaries received more care in the ED within 1 year postpartum compared with those enrolled in other commercial plans. This highlights potential issues in postpartum care access.

A Primary Care-Based Quality Improvement Project to Reduce Asthma Emergency Department Visits.

Asthma exacerbation is a common and often preventable cause of Emergency Department (ED) utilization. Children eligible for Medicaid are at increased risk of poor asthma control and subsequent ED visits. In 2010, we implemented a multicomponent longitudinal quality improvement project to improve pediatric asthma care for our primary care population, which was 90% Medicaid-eligible. Our goal was to reduce asthma-related ED visits by patients ages 2 to 18 years by 3% annually. The setting was a multisite large urban high-risk primary care network affiliated with a children's hospital. We implemented 5 sequential interventions within our network of pediatric primary care centers to increase: use of asthma action plans by clinicians, primary care-based Asthma Specialty Clinic visits (extended asthma visits in the main primary care site), use of a standard asthma note at all visits, documentation of the Asthma Control Test, and step-up therapy for children with poorly controlled asthma. At baseline in 2010, there were 21.7 asthma-related ED visits per 1000 patients per year. By 2019, asthma-related ED visits decreased to 14.5 per 1000 patients per year, a 33% decrease, with 2 center line shifts over time. We achieved and sustained our goal metrics for 4 of 5 key interventions. We reduced ED utilization for asthma in a large, high-risk pediatric population. The interventions implemented and used over time in this project demonstrate that sustainable outcomes can be achieved in a large network of primary care clinics.

Health care utilization and outcomes of patients seen by virtual urgent care versus in-person emergency department care.

Virtual urgent care (VUC) is intended to support diversion of patients with low-acuity complaints and reduce the need for in-person emergency department visits. We aimed to describe subsequent health care utilization and outcomes of patients who used VUC compared with similar patients who had an in-person emergency department visit. We used patient-level encounter data that were prospectively collected for patients using VUC services provided by 14 pilot programs in Ontario, Canada. We linked the data to provincial administrative databases to identify subsequent 30-day health care utilization and outcomes. We defined 2 subgroups of VUC users; those with a documented prompt referral to an emergency department by a VUC provider, and those without. We matched patients in each cohort to an equal number of patients presenting to an emergency department in person, based on encounter date, medical concern and the logit of a propensity score. For the subgroup of patients not promptly referred to an emergency department, we matched patients to those who were seen in an emergency department and then discharged home. Of the 19 595 patient VUC visits linked to administrative data, we matched 2129 patients promptly referred to the emergency department by a VUC provider to patients presenting to the emergency department in person. Index visit hospital admissions (9.4% v. 8.7%), 30-day emergency department visits (17.0% v. 17.5%), and hospital admissions (12.9% v. 11.0%) were similar between the groups. We matched 14 179 patients who were seen by a VUC provider with no documented referral to the emergency department. Patients seen by VUC were more likely to have a subsequent in-person emergency department visit within 72 hours (13.7% v. 7.0%), 7 days (16.5% v. 10.3%) and 30 days (21.9% v. 17.9%), but hospital admissions were similar within 72 hours (1.1% v. 1.3%), and higher within 30 days for patients who were discharged home from the emergency department (2.6% v. 3.4%). The impact of the provincial VUC pilot program on subsequent health care utilization was limited. There is a need to better understand the inherent limitations of virtual care and ensure future virtual providers have timely access to in-person outpatient resources, to prevent subsequent emergency department visits.

Social Navigation for Adolescent Emergency Department Patients: A Randomized Clinical Trial

PurposeAdolescent emergency department (ED) patients have unmet social needs that contribute to ED use. This study aimed to evaluate the effect of social needs navigation for adolescents on subsequent ED visits and community resource use and to identify characteristics associated with elevated social risk. MethodsBetween July 2017 and August 2019, we used a random date generator to establish intervention and control group enrollment dates. All adolescents completed a social needs survey. Adolescents enrolled on intervention dates received in-person, risk-tailored social needs navigation. Those enrolled on control dates received a preprinted resource guide. We used chart review and follow-up calls to assess 12-month ED revisits and community resource use. Logistic regression was used to compare these outcomes between groups. We measured the association between ≥3 reported unmet needs and characteristics hypothesized a priori to be associated with elevated social risk (nonurgent visits, obesity, or any of nine “socially sensitive” chief complaints) using logistic regression. ResultsA total of 399 adolescents were randomized. There was no difference between groups in the number of ED revisits. There was increased community resource use in the intervention group (adjusted odds ratio [aOR]: 3.5 [95% confidence interval {CI}: 1.5, 8.2]). Adolescents with a socially sensitive chief complaint had increased odds of ≥3 unmet needs (aOR: 2.2 [95% CI: 1.3, 3.6]), as did those with food insecurity in a post hoc analysis (aOR: 9.9 [95% CI: 4.0, 24.6]). DiscussionSocial needs navigation increased community resource use but not subsequent ED visits. Adolescents with socially sensitive chief complaints or food insecurity reported increased unmet needs.

A descriptive study of screening and navigation on health-related social needs in a safety-net hospital emergency department

BackgroundHealth-related social needs (HRSN) have been associated with worse clinical outcomes, increased Emergency Department (ED) utilization and higher healthcare costs. The ED is uniquely positioned to bring HRSN screening to the bedside and develop effective interventions. We evaluated whether navigation services for high-risk patients led to the resolution of HRSN. MethodsNavigators screened a convenience sample of patients for HRSN with the Accountable Health Communities Screening Tool from October 2019 to January 2022. Patients with HRSN were considered high-risk if they had at least two ED visits in the previous 12 months. Patients who were high-risk were eligible for navigation including community referrals and one-on-one close follow-up. The HRSN status (resolved, in-progress, unable to resolve) was queried from the Centers for Medicare and Medicaid database. The state hospital association provided data on ED visits and inpatient hospitalizations within 6 months of the screening visit. ResultsOf 185,470 ED visits, HRSN screening occurred in 4050 (2%). HRSN were self-reported in 48% (1944) of patient visits, with 71% of these (1379) considered high-risk. 15% of high-risk patients with HRSN opted out of navigation. Food insecurity was the most identified HRSN (35%) followed by housing instability (26%), transportation needs (24%) and utility assistance (15%). Food insecurity was the most resolved HRSN (39%, in-progress 32%) followed by utility assistance (37%, in-progress 26%), transportation needs (35%, in-progress 35%) and housing instability (28%, in-progress 36%). High-risk visits in which the patient or guardian accepted navigation were less likely to be associated with an ED visit within 6 months of the screening visit (51%) compared to high-risk patients in which the patient or guardian opted out of navigation (61%, p < 0.001), but there was no difference in inpatient hospitalizations (p = 0.427). ConclusionsDuring the study period, one-third of HRSN were successfully resolved with another one-third in-progress. Navigation in high-risk patients was associated with fewer subsequent ED visits.

A Previously Healthy Infant with Lemierre Syndrome in the Emergency Department: Case Report.

Lemierre syndrome (LS) is a rare condition with a high mortality risk. It is well described in older children and young adults involving bacteremia, thrombophlebitis, and metastatic abscess commonly due to Fusobacterium infections. Young, pre-verbal children are also susceptible to LS; thus, careful attention must be given to their pattern of symptoms and history to identify this condition in the emergency department (ED). A 12-month-old previously healthy boy with a recent diagnosis of acute otitis media and viral illness presented to the ED with a complaint of fever. Additional symptoms developed at the head and neck and were noted on subsequent ED visits. Advanced imaging revealed significant lymphadenopathy and deep space inflammation extending to the mediastinum. Subsequent imaging confirmed extensive sinus and deep vein thromboses, consistent with LS. Methicillin-resistant Staphylococcus aureus (MRSA) was the only organism identified. After surgical debridement, appropriate intravenous antibiotics, and heparin anticoagulation therapy, the patient experienced full recovery after prolonged hospitalization. A febrile infant with multiple acute care visits and development of lymphadenopathy, decreased oral intake, decreased cervical range of motion, and sepsis should raise suspicion for Lemierre syndrome. The medical evaluation of deep neck spaces and deep veins should be similar to that of older children and adults with LS, including advanced imaging of the head and neck. However, medical management should particularly target MRSA due to its emerging prevalence among infantile LS cases. Further research is necessary to determine the optimal management strategies of LS for this age group.

Emergency Care Utilization for Mental and Sexual Health Concerns Among Adolescents Following Sexual Assault: A Retrospective Cohort Study

PurposeThis study aimed to explore the health outcomes of adolescent survivors of sexual assault, as measured by subsequent emergency department (ED) utilization for mental and sexual health concerns. MethodsThis retrospective cohort study used the Pediatric Health Information System (PHIS) database. We included patients aged 11–18 years seen at a PHIS hospital with a primary diagnosis of sexual assault. The control group included age- and sex-matched patients seen for an injury. Participants were followed in PHIS for 3–10 years; subsequent ED visits for suicidality, sexually transmitted infection, pelvic inflammatory disease (PID), or pregnancy were identified, and likelihoods of each were compared using Cox proportional hazards models. ResultsThe study population included 19,706 patients. ED return visit rates in the sexual assault and control groups were 7.9% versus 4.1% for suicidality, 1.8% versus 1.4% for sexually transmitted infection, 2.2% versus 0.8% for PID, and 1.7% versus 1.0% for pregnancy, respectively. Compared to controls, sexual assault patients were significantly more likely to return to the ED for suicidality throughout the follow-up period, with the highest hazard ratio of 6.31 (95% confidence interval 4.46–8.94) during the first 4 months. Sexual assault patients also had higher likelihood of returning for PID (hazard ratio 3.80, 95% confidence interval 3.07–4.71) throughout the follow-up period. DiscussionAdolescents seen in the ED for sexual assault were significantly more likely to return to the ED for suicidality and sexual health concerns, highlighting the need for increased allocation of research and clinical resources to improve their care.

Alpha Blocker Medical Expulsive Therapy for Ureteral Stones—Usage of Health Care Resources

Abstract Objective: To study the effects of alpha blocker prescription for ureteral stones on health care resources. Methods: In this retrospective study, patients with a new ureteral stone diagnosis were selected from a commercial claims database between 2011 and 2016. We examined data from patients who were and were not prescribed an alpha blocker for ureteral stone diagnosis. Comparative analyses were performed between these groups at 30 and 90 days postdiagnosis. We evaluated the need for surgical intervention, repeat imaging, emergency department (ED) visits, adverse events, and total medical claims cost. Results: Of 70,599 patients with ureteral stones, alpha blockers were prescribed to 51.1% for a median duration of ten days. At 30 and 90 days after index diagnosis, alpha blocker treated patients were more likely to undergo surgical intervention (P &lt; .01, 1.06 HR), have additional imaging studies (P &lt; .01, 1.37 HR), and visit the emergency department (P &lt; .01, 1.19 HR). Total medical costs at 30 and 90 days were increased by 11.3% and 10.1%, respectively, for patients treated with an alpha blocker (P &lt; .01). Conclusions: Patients who were prescribed an alpha blocker for a diagnosis of ureteral stone had increased surgical interventions, subsequent ED visits, additional imaging studies, and overall total cost to the health care system compared with patients not on alpha blockers. In addition to uncertain and disputed efficacy, the negative impact on health care resources should also be considered in the decision for the use of alpha blockers for ureteral stones.

Association of chronic opioid therapy with emergency department visits and hospitalizations among super-utilizers

Abstract Objectives Patients with complex medical needs and high inpatient utilization frequently use opioids for non-malignant chronic pain. We examine the association between chronic opioid therapy and healthcare utilization among high-need, high-cost patients insured by Medicare. Methods This study is a retrospective cohort study of Medicare beneficiaries in a medically underserved metropolitan area. Patients were included in the study if they had ≥2 hospitalizations or ≥1 hospitalization and ≥2 emergency department (ED) visits in a 6-month-period preceding an index hospitalization between July 2011 and June 2014. Exclusion criteria included substance abuse, psychosis and malignancy. Multivariable negative binomial regression models assessed associations between baseline opioid medication use and subsequent ED and hospital visits for the study population and two subgroups: (1) those with chronic pain and (2) those with both chronic pain and a primary care provider. Key findings The majority of high-need, high-cost patients filled opioid prescriptions of ≥7-day supply (51%). Yet only 2.7% of patients with chronic pain received an opioid prescription of ≥7-day supply from an ED provider in the baseline period. Overall (n = 677), receipt of a ≥7-day opioid supply was positively associated with subsequent ED utilization but not subsequent hospitalization. Among those with chronic pain and ≥1 primary care practice visit (N = 481), opioid use was associated with inpatient utilization but not ED utilization. Receipt of adjuvant pain prescriptions was not protective of hospitalizations or ED visits. Conclusions Chronic pain and opioid therapy are common among high-need, high-cost patients and they are independently associated with higher ED and hospital utilization. Novel patient-centred outpatient pain management strategies have potential to reduce inpatient care in this population.

Implementation of a compulsory clinical pharmacist-led medication deprescribing intervention in high-risk seniors in the emergency department.

The objective of this study was to assess the impact of an emergency department (ED) deprescribing intervention for geriatric adults. We hypothesized that pharmacist-led medication reconciliation for at-risk aging patients would increase the 60-day case rate of primary care provider (PCP) deprescribing of potentially inappropriate medications (PIMs). This was a retrospective, before-and-after intervention pilot study conducted at an urban Veterans Affairs ED. In November 2020, a protocol utilizing pharmacists to perform medication reconciliations for patients 75 years or older who screened positive using an Identification of Seniors at Risk tool at triage was implemented. Reconciliations focused on identifying PIMs and providing deprescribing recommendations to patients' PCPs. A preintervention group was collected between October 2019 and October 2020, and a postintervention group was collected between February 2021 to February 2022. The primary outcome compared case rates of PIM deprescribing in the preintervention group to the postintervention group. Secondary outcomes include per-medication PIM deprescribing rate, 30-day PCP follow-up visits, 7- and 30-day ED visits, 7- and 30-day hospitalizations, and 60-day mortality. A total of 149 patients were analyzed in each group. Both groups were similar in age and sex, with an average age of 82 years and 98% male. The case rate of PIM deprescribing at 60 days was 11.1% preintervention compared to 57.1% postintervention (p< 0.001). Preintervention, 91% of PIMs remained unchanged at 60 days compared to 49% (p< 0.05) postintervention. Regardless of PIM identification, the 30-day primary care follow-up rate increased postintervention: 31.5% and 55.7% (p< 0.0001), respectively. There was no improvement in 7- or 30-day subsequent ED visits, hospitalization, or mortality. Pharmacist-led medication reconciliation in high-risk geriatric patients was associated with an increase both in the rate of PIM deprescribing and in post-ED primary care engagement.

Ambulatory follow-up among publicly insured children discharged from the emergency department.

While children discharged from the emergency department (ED) are frequently advised to follow up with ambulatory care providers, the extent to which this occurs is unknown. We sought to characterize the proportion of publicly insured children who have an ambulatory visit following ED discharge, identify factors associated with ambulatory follow-up, and evaluate the association of ambulatory follow-up with subsequent hospital-based health care utilization. We performed a cross-sectional study of pediatric (<18 years) encounters during 2019 included in the IBM Watson Medicaid MarketScan claims database from seven U.S. states. Our primary outcome was an ambulatory follow-up visit within 7 days of ED discharge. Secondary outcomes were 7-day ED return visits and hospitalizations. Logistic regression and Cox proportional hazards were used for multivariable modeling. We included 1,408,406 index ED encounters (median age 5 years, IQR 2-10 years), for which a 7-day ambulatory visit occurred in 280,602 (19.9%). Conditions with the highest proportion of 7-day ambulatory follow-up included seizures (36.4%); allergic, immunologic, and rheumatologic diseases (24.6%); other gastrointestinal diseases (24.5%); and fever (24.1%). Ambulatory follow-up was associated with younger age, Hispanic ethnicity, weekend ED discharge, ambulatory encounters prior to the ED visit, and diagnostic testing performed during the ED encounter. Ambulatory follow-up was inversely associated with Black race and ambulatory care-sensitive or complex chronic conditions. In Cox models, ambulatory follow-up was associated with a higher hazard ratio (HR) of subsequent ED return (HR range 1.32-1.65) visit and hospitalization (HR range 3.10-4.03). One-fifth of children discharged from the ED have an ambulatory visit within 7 days, which varied by patient characteristics and diagnoses. Children with ambulatory follow-up have a greater subsequent health care utilization, including subsequent ED visit and/or hospitalization. These findings identify the need to further research the role and costs associated with routine post-ED visit follow-up.

Mobile Integrated Health Interventions for Older Adults: A Systematic Review.

Mobile integrated health (MIH) interventions have not been well described in older adult populations. The objective of this systematic review was to evaluate the characteristics and effectiveness of MIH programs on health-related outcomes among older adults. We searched Ovid MEDLINE, Ovid EMBASE, CINAHL, AgeLine, Social Work Abstracts, and The Cochrane Library through June 2021 for randomized controlled trials or cohort studies evaluating MIH among adults aged 65 and older in the general community. Studies were screened for eligibility against predefined inclusion/exclusion criteria. Using at least 2 independent reviewers, quality was appraised using the Downs and Black checklist and study characteristics and findings were synthesized and evaluated for potential bias. Screening of 2,160 records identified 15 studies. The mean age of participants was 67 years. The MIH interventions varied in their focus, community paramedic training, types of assessments and interventions delivered, physician oversight, use of telemedicine, and post-visit follow-up. Studies reported significant reductions in emergency call volume (5 studies) and immediate emergency department (ED) transports (3 studies). The 3 studies examining subsequent ED visits and 4 studies examining readmission rates reported mixed results. Studies reported low adverse event rates (5 studies), high patient and provider satisfaction (5 studies), and costs equivalent to or less than usual paramedic care (3 studies). There is wide variability in MIH provider training, program coordination, and quality-based metrics, creating heterogeneity that make definitive conclusions challenging. Nonetheless, studies suggest MIH reduces emergency call volume and ED transport rates while improving patient experience and reducing overall health care costs.

Violent Injury as a Predictor of Subsequent Assault-Related Emergency Department Visits Among Adolescents

PurposeTo measure the risk of a subsequent assault-related emergency department (ED) visit in assault injured adolescents as compared to those who initially presented for non-assault related injuries. MethodsThis was a historical cohort study of youth (ages 10–18 years) seen at two pediatric EDs between 2016 and 2019. Participants were included if their visit had an International Classification of Diseases-10 code for assaultive injury or accidental injury (motor vehicle collisions (MVC) and sports injuries). We calculated the rate of a subsequent ED visit for an assault-related injury, and then used survival analysis to compare time to subsequent ED visit with an assault-related injury between study and comparison groups. ResultsA total of 6125 adolescents met inclusion criteria (Assault: n = 2782, 45.4%; MVC: n = 1834, 29.9%; Sports n = 1509, 24.6%). The overall rate per 100 person years of a subsequent assault-related ED visit was 5.6 (n = 344). Patients who initially presented with an assault-related injury had an increased adjusted relative risk (aRR) of return for a subsequent ED visit for an assault-related injury when compared to MVC patients (aRR 17.6 [95% CI: 9.6, 32.2]). Kaplan-Meier time to event analysis found that patients in the assault injury group have a higher probability of a subsequent ED visit for an assault-related injury compared to patients in the MVC injury group (adjusted hazard ratio (aHR): 17.7 [95% CI: 9.67, 32.42]). DiscussionAdolescents injured by assault are more likely to return to the ED for a subsequent assault-related injury compared to adolescents who initially present with non-assault-related injuries.
