Association of Timely Outpatient Follow-Up and Readmission Risk in a Mobile Integrated Health Program.

The objective was to identify medical conditions associated with 30-day readmission, determine patient characteristics for which outpatient follow-up is most associated with reduced readmission, and evaluate how readmission risk changes with time to outpatient follow-up within a mobile integrated health-community paramedicine (MIH-CP) program. This retrospective observational study used data from 1,118 adult patient enrollments in a MIH-CP program operating in Baltimore, Maryland, from May 14, 2018, to December 21, 2021. Bivariate analysis identified chronic disease exacerbations associated with higher 30-day readmission risk. Kaplan-Meier curves and Cox proportional hazard regressions were used to measure how hazard of readmission changes with outpatient follow-up and how that association may vary with other factors. Receiver operating characteristic analysis was used to evaluate how well time to follow-up could predict 30-day readmission. Timely outpatient follow-up was associated with a significant reduction in hazard of readmission for patients aged 50 and younger and for patients with fewer than 5 social determinants of health needs identified. No significant association between readmission and specific chronic disease exacerbations was observed. An optimal follow-up time frame to reduce readmissions could not be identified. Timely outpatient follow-up may be effective for reducing readmissions in younger patients and patients who are less socially complex. Programs and policies aiming to reduce 30-day readmissions may have more success by expanding efforts to include these patients.

Association Between Primary Care Availability and Emergency Medical Services Utilization.

BACKGROUND: Emergency medical services (EMS) contribute to the vital role of providing health care to an individual by delivering time-sensitive, episodic treatment to patients with acute illnesses. Understanding which factors impact EMS utilization can help guide policies and allocate resources more effectively. Increasing primary care access has often been touted to decrease unnecessary emergency care utilization. OBJECTIVES: This study seeks to determine whether a relationship exists between access to primary care and EMS utilization. METHODS: Using data from the National Emergency Medical Services Information System, Area Health Resources Files, and County Health Rankings and Roadmaps, U.S. county-level data were analyzed to determine whether increased access to primary care (and insurance coverage) was associated with decreased EMS utilization. RESULTS: Higher primary care availability is associated with less EMS utilization only when insurance coverage in the community surpassed 90%. CONCLUSIONS: Insurance coverage can play an important role in decreasing EMS utilization and may also impact the effect of increased primary care physician availability on EMS utilization in a region.

Evaluating Social Determinants of Health in a Mobile Integrated Healthcare-Community Paramedicine Program.

In 2018, the University of Maryland Medical Center and the Baltimore City Fire Department implemented a community paramedicine program to help medically or socially complex patients transition from hospital to home and avoid hospital utilization. This study describes how patients' social determinants of health (SDoH) needs were identified, and measures the association between needs and hospital utilization. SDoH needs were categorized into ten domains. Multinomial logistic regression was used to measure association between identified SDoH domains and predicted risk of readmission. Poisson regression was used to measure association between SDoH domains and actual 30-day hospital utilization. The most frequently identified SDoH needs were in the Coordination of Healthcare (37.7%), Durable Medical Equipment (18.8%), and Medication (16.3%) domains. Compared with low-risk patients, patients with an intermediate risk of readmission were more likely to have needs within the Coordination of Healthcare (RRR [95% CI] 1.12 [1.01, 1.24], p = 0.032) and Durable Medical Equipment (RRR = 1.13 [1.00, 1.27], p = 0.046) domains. Patients with the highest risk for readmission were more likely to have needs in the Utilities domain (RRR = 1.76 [0.97, 3.19], p = 0.063). Miscellaneous domain needs, such as requiring a social security card, were associated with increased 30-day hospital utilization (IRR = 1.23 [0.96, 1.57], p = 0.095). SDoH needs within the Coordination of Healthcare, Durable Medical Equipment, and Utilities domains were associated with higher predicted 30-day readmission, while identification documentation and social services needs were associated with actual readmission. These results suggest where to allocate resources to effectively diminish hospital utilization.

Evaluating the Impact of a Mobile Integrated Health‒Community Paramedicine Program on Health-Related Social Needs and Hospital Readmissions.

OBJECTIVE: Evaluate a mobile integrated health-community paramedicine program's effect on addressing health-related social needs and their association with hospital readmissions. METHODS: This observational study enrolled 1,003 patients from 5/4/2018-7/23/21. Descriptive statistics summarize social needs. A Poisson regression model examined the association of interventions for social needs with 30-day readmissions. RESULTS: Patients who had their medication-related needs fully addressed had a 65% lower rate of total 30-day readmission compared with patients who had no such needs fully addressed (IRR=0.35, 95% CI 0.18-0.68, P=.002). No variables reached statistical significance related to unplanned 30-day readmissions, aside from the HOSPITAL Score. CONCLUSIONS: Assisting patients with medication-related needs is associated with reductions in overall 30-day readmissions. Interventions within most domains were not associated with reductions in overall or unplanned 30-day readmissions. This program had greater success addressing needs with one-step interventions, suggesting additional time and resources may be necessary to address complex social needs.

Analysis of Readmissions in a Mobile Integrated Health Transitional Care Program Using Root Cause Analysis and Common Cause Analysis.

ABSTRACT: Mobile integrated health and community paramedicine (MIH-CP) programs are gaining popularity in the United States as a strategy to address the barriers to healthcare access and appropriate utilization. After one year of operation, leadership of Baltimore City's MIH-CP program was interested in understanding the circumstances surrounding readmission for enrolled patients and to incorporate quality improvement tools to direct program development. Retrospective chart review was performed to determine preventable versus unpreventable readmissions with a hypothesis that deficits in social determinants of health would play a more significant role in preventable readmissions. In the studied population, at least one root cause that can be considered a social determinant of health was present in 75.8% of preventable readmissions versus only 15.2% of unpreventable readmissions. Root Cause Analysis highlighted health literacy, functional status, and behavioral health issues among the root causes that most heavily influence preventable readmissions. Common Cause Analysis results suggest our MIH-CP program should focus its resources on mitigating poor health literacy and functional status. This project's findings successfully directed leadership of the city's MIH-CP program to modify program processes and advocate for the use of these quality improvement tools for other MIH-CP programs.

Analysis of an Alternative Model of Definitive Care For Low-Acuity Emergency Calls: A Natural Experiment.

BACKGROUND: Emergency medical services (EMS) diversion strategies attempt to limit the impact of low-acuity care on emergency department (ED) crowding, but evidence supporting these strategies is scarce. OBJECTIVE: This study aims to measure the effect of a treat-in-place and alternative destination program on ED transports and EMS utilization. METHODS: We used a natural experiment study design to measure effects of a pilot prehospital diversion program on ED transport, number of EMS vehicles dispatched, and EMS time on task for low-acuity emergency calls in a midsized urban setting characterized by a high prevalence of health disparities, concentrated poverty, and limited access to primary care between October 2018 and January 2020. We also used direct variable cost to estimate the return on investment attributable to avoided ED visits. RESULTS: Of 3725 calls that met eligibility criteria, the program responded to 1084 (29.1%), with 56.7% of those resulting in an ED visit, compared with 64.6% of the 492 control calls that were eligible but were dispatched when program services were unavailable. Of 1084 calls receiving response, 213 (19.6%) were enrolled in the program, and 8.5% of those were transported by EMS to the ED. Adjusted results show EMS time on task was 23.4 min less for enrolled calls vs. controls. The program can achieve a positive return on investment by enrolling 2.9 patients/day. CONCLUSIONS: A prehospital diversion program reduced ED visits and EMS transport times. Improved targeting of patients for enrollment would further increase the intervention's efficacy and cost savings.

The effect of a mobile integrated health program on health care cost and utilization.

OBJECTIVE: To measure the effect of a mobile integrated health community paramedicine (MIH-CP) transitional care program on hospital utilization, emergency department visits, and charges. DATA SOURCES: Retrospective secondary data from the electronic health record and regional health information exchange were used to analyze patients discharged from a large academic medical center and an affiliated community hospital in Baltimore, Maryland, May 2018-October 2019. STUDY DESIGN: We performed an observational study comparing patients enrolled in an MIH-CP program to propensity-matched controls. Propensity scores were calculated using measures of demographics, clinical characteristics, social determinants of health, and prior health care utilization. The primary outcome is inpatient readmission within 30 days of discharge. Secondary outcomes include excess days in acute care 30 days after discharge and emergency department visits, observation hospitalizations, and total health care charges within 30 and 60 days of discharge. DATA COLLECTION: Included patients were over 18 years old, discharged to home from internal/family medicine services, and live in eligible ZIP codes. The intervention group was enrolled in the MIH-CP program; controls met inclusion criteria but were not enrolled during the study period. PRINCIPAL FINDINGS: The adjusted model showed no difference in 30-day inpatient readmission between 464 enrolled patients and propensity-matched controls (adjusted incidence rate ratio = 1.19, 95% confidence interval [CI] [0.89, 1.60]). There was a higher rate of observation hospitalizations within 30 days of index discharge for MIH-CP patients (adjusted incidence rate ratio = 1.78, 95% CI = [1.01, 3.14]). This difference did not persist at 60 days, and there were no differences in other secondary outcomes. CONCLUSIONS: We found no significant difference in short-term health care utilization or charges between patients enrolled in an MIH-CP transitional care program and propensity-matched controls. This highlights the importance of well-controlled, robust evaluations of effectiveness in novel care-delivery systems.

Masking for COVID-19 Is Associated with Decreased Emergency Department Utilization for Non-COVID Viral Illnesses and Respiratory Conditions in Maryland.

BACKGROUND: Masking, which is known to decrease the transmission of respiratory viruses, was not widely practiced in the United States until the coronavirus disease 2019 (COVID-19) pandemic. This provides a natural experiment to determine whether the percentage of community masking was associated with decreases in emergency department (ED) visits due to non-COVID viral illnesses (NCVIs) and related respiratory conditions. METHODS: In this observational study of ED encounters in a 11-hospital system in Maryland during 2019-2020, year-on-year ratios for all complaints were calculated to account for "lockdowns" and the global drop in ED visits due to the pandemic. Encounters for specific complaints were identified using the International Classification of Diseases, version 10. Encounters with a positive COVID test were excluded. Linear regression was used to determine the association of publicly available masking data with ED visits for NCVI and exacerbations of asthma and chronic obstructive pulmonary disease (COPD), after adjusting for patient age, sex, and medical history. RESULTS: There were 285,967 and 252,598 ED visits across the hospital system in 2019 and 2020, respectively. There was a trend toward an association between the year-on-year ratio for all ED visits and the Maryland stay-at-home order (parameter estimate = -0.0804, P = .10). A 10% percent increase in the prevalence of community masking was associated with a 17.0%, 8.8%, and 9.4% decrease in ED visits for NCVI and exacerbations of asthma exacerbations and chronic obstructive pulmonary disease, respectively (P < .001 for all). CONCLUSIONS: Increasing the prevalence of masking is associated with a decrease in ED visits for viral illnesses and exacerbations of asthma and COPD. These findings may be valuable for future public health responses, particularly in future pandemics with respiratory transmission or in severe influenza seasons.

The Application of a Hospital Medical Surge Preparedness Index to Assess National Pandemic and Other Mass Casualty Readiness.

EXECUTIVE SUMMARY: This article describes the use and findings of the Hospital Medical Surge Preparedness Index (HMSPI) tool to improve the understanding of hospitals' ability to respond to mass casualty events such as the COVID-19 pandemic. For this investigation, data from the U.S. Census Bureau, the Dartmouth Atlas Project, and the 2005 to 2014 annual surveys of the American Hospital Association (AHA) were analyzed. The HMSPI tool uses variables from the AHA survey and the other two sources to allow facility, county, and referral area index calculations. Using the three data sets, the HMSPI also allows for an index calculation for per capita ratios and by political (state or county) boundaries. In this use case, the results demonstrated increases in county and state HMSPI scores through the period of analysis; however, no statistically significant difference was found in HMSPI scores between 2013 and 2014. The HMSPI builds on the limited scientific foundation of medical surge preparedness and could serve as an objective and standardized measure to assess the nation's medical readiness for crises such as the COVID-19 pandemic and other large-scale emergencies such as mass shootings. Future studies are encouraged to refine the score, assess the validity of the HMSPI, and evaluate its relevance in response to future legislative and executive policies that affect preparedness measures.

Development of a Logic Model to Guide Implementation and Evaluation of a Mobile Integrated Health Transitional Care Program.

To provide medical and social services to underserved communities, many health care organizations across the United States have expanded the role of emergency medical services to include mobile integrated health and community paramedicine (MIH-CP). Although MIH-CP programs differ in structure and setting, many share the common goal of improving health through home-based, patient-centered care management models. Ideally, these innovative programs reduce use of health care services, including 911 (US emergency system) calls and emergency department visits. In 2018 a large, urban academic medical center partnered with the city's fire department to establish an MIH-CP program to support patients as they transition in their first 30 days at home after hospitalization. Prior to launch, a multidisciplinary team developed a logic model to guide development, implementation, and evaluation of this complex and innovative program. This paper describes the team's structured process for developing a logic model. It also describes key components of the initial logic model and the Transitional Health Support program structure, as well as subsequent revisions to both.

Innovative Use of Emergency Medicine Providers in an Urban Setting to Reduce Overutilization of 9-1-1.

BACKGROUND: Emergency Departments (ED) and Emergency Medical Services (EMS) are relied on to address nonemergent needs causing long ED wait times. Baltimore City EMS provided over 100,000 transports, many for low-acuity medical needs. OBJECTIVE: Minor Definitive Care Now (MDCN) is designed to address low-acuity complaints and decrease ED visits. MDCN provides low-acuity 9-1-1 callers the option of on-scene evaluation and treatment. For patients requiring additional resources, but not needing an ED, an alternate destination is considered. METHODS: Patients were screened low acuity by EMS personnel and voluntarily enrolled in MDCN. A questionnaire was given to patients after their visit to assess satisfaction. CRISP, a database for hospital visits in Maryland, was reviewed to assess if patients went to the ED after an MDCN visit. RESULTS: In 1 year of service, 168 calls were screened, with 144 patients consenting to treatment by the MDCN team. Of enrolled patients: 94 (65%) were treated on the scene, 37 (26%) were transported to an urgent care facility, 1 (0.6%) was transported to their primary care provider for a same-day appointment, and 12 (8.4%) were transported to the ED after further evaluation. Of the 94 patients treated on scene, 3 (3.2%) presented to a local ED in the surrounding area within 72 h. On review, there were no safety issues identified or deficits in the clinical care provided on scene. CONCLUSION: This innovative model of on-scene evaluation and treatment can potentially reduce transports, decrease ED wait times, and reduce costs, in an effective and efficient way.

Development of a Hospital Medical Surge Preparedness Index using a national hospital survey.

To generate a Hospital Medical Surge Preparedness Index that can be used to evaluate hospitals across the United States in regard to their capacity to handle patient surges during mass casualty events. Data from the American Hospital Association's annual survey, conducted from 2005 to 2014. Our sample comprised 6239 hospitals across all 50 states, with an annual average of 5769 admissions. An extensive review of the American Hospital Association survey was conducted and relevant variables applicable to hospital inpatient services were extracted. Subject matter experts then categorized these items according to the following subdomains of the "Science of Surge" construct: staff, supplies, space, and system. The variables within these categories were then analyzed through exploratory and confirmatory factor analyses, concluding with the evaluation of internal reliability. Based on the combined results, we generated individual (by hospital) scores for each of the four metrics and an overall score. The exploratory factor analysis indicated a clustering of variables consistent with the "Science of Surge" subdomains, and this finding was in agreement with the statistics generated through the confirmatory factor analysis. We also found high internal reliability coefficients, with Cronbach's alpha values for all constructs exceeding 0.9. A novel Hospital Medical Surge Preparedness Index linked to hospital metrics has been developed to assess a health care facility's capacity to manage patients from mass casualty events. This index could be used by hospitals and emergency management planners to assess a facility's readiness to provide care during disasters.

Trends in the Contribution of Emergency Departments to the Provision of Hospital-Associated Health Care in the USA.

Traditional approaches to assessing the health of populations focus on the use of primary care and the delivery of care through patient-centered homes, managed care resources, and accountable care organizations. The use of emergency departments (EDs) has largely not been given consideration in these models. Our study aimed to determine the contribution of EDs to the health care received by Americans between 1996 and 2010 and to compare it with the contribution of outpatient and inpatient services using National Hospital Ambulatory Medical Care Survey and National Hospital Discharge Survey databases. We found that EDs contributed an average of 47.7% of the hospital-associated medical care delivered in the United States, and this percentage increased steadily over the 14-year study period. EDs are a major source of medical care in the United States, especially for vulnerable populations, and this contribution increased throughout the study period. Including emergency care within health reform and population health efforts would prove valuable to supporting the health of the nation.

Disaster Preparedness and Response for the Burn Mass Casualty Incident in the Twenty-first Century.

The effective and efficient coordination of emergent patient care at the point of injury followed by the systematic resource-based triage of casualties are the most critical factors that influence patient outcomes after mass casualty incidents (MCIs). The effectiveness and appropriateness of implemented actions are largely determined by the extent and efficacy of the planning and preparation that occur before the MCI. The goal of this work was to define the essential efforts related to planning, preparation, and execution of acute and subacute medical care for disaster burn casualties. This type of MCI is frequently referred to as a burn MCI."

Value-Based Approaches for Emergency Care in a New Era.

Although emergency departments (EDs) play an integral role in the delivery of acute unscheduled care, they have not been fully integrated into broader health care reform efforts. Communication and coordination with the ambulatory environment remain limited, leaving ED care disconnected from patients' longitudinal care. In a value-based environment focused on improving quality, decreasing costs, enhancing population health, and improving the patient experience, this oversight represents a missed opportunity for emergency care. When integrated with primary and subspecialty care, emergency care might meet the needs of patients, providers, and payers more efficiently than yet realized. This article uses the Merit-Based Incentive Payment System from the Medicare Access and CHIP Reauthorization Act as a framework to outline a strategy for improving the value of emergency care, including integrating quality and resource use measures across health care delivery settings and populations, encouraging care coordination from the ED, and implementing robust health information exchange systems.

Junctional Tourniquet Training Experience.

Since 2009, out-of-hospital care of junctional hemorrhage bleeding from the trunk-appendage junctions has changed, in part, due to the newly available junctional tourniquets (JTs) that have been cleared by the US Food and Drug Administration. Given four new models of JT available in 2014, several military services have begun to acquire, train, or even use such JTs in care. The ability of users to be trained in JT use has been observed by multiple instructors. The experience of such instructors has been broad as a group, but their experience as individuals has been neither long nor deep. A gathering into one source of the collective experience of trainers of JT users could permit a collation of useful information to include lessons learned, tips in skill performance, identification of pitfalls of use to avoid, and strategies to optimize user learning. The purpose of the present review is to record the experiences of several medical personnel in their JT training of users to provide a guide for future trainers.

An Economic Analysis and Approach for Health Care Preparedness in a Substate Region.

OBJECTIVE: To demonstrate the application of economics to health care preparedness by estimating the financial return on investment in a substate regional emergency response team and to develop a financial model aimed at sustaining community-level disaster readiness. METHODS: Economic evaluation methods were applied to the experience of a regional Pennsylvania response capability. A cost-benefit analysis was performed by using information on funding of the response team and 17 real-world events the team responded to between 2008 and 2013. By use of the results of the cost-benefit analysis as well as information on the response team's catchment area, a risk-based insurance-like membership model was built. RESULTS: The cost-benefit analysis showed a positive return after 6 years of investment in the regional emergency response team. Financial modeling allowed for the calculation of premiums for 2 types of providers within the emergency response team's catchment area: hospitals and long-term care facilities. CONCLUSION: The analysis indicated that preparedness activities have a positive return on their investment in this substate region. By applying economic principles, communities can estimate their return on investment to make better business decisions in an effort to increase the sustainability of emergency preparedness programs at the regional level.

Recent advances in medical device triage technologies for chemical, biological, radiological, and nuclear events.

In 2010, the US Food and Drug Administration (Silver Spring, Maryland USA) created the Medical Countermeasures Initiative with the mission of development and promoting medical countermeasures that would be needed to protect the nation from identified, high-priority chemical, biological, radiological, or nuclear (CBRN) threats and emerging infectious diseases. The aim of this review was to promote regulatory science research of medical devices and to analyze how the devices can be employed in different CBRN scenarios. Triage in CBRN scenarios presents unique challenges for first responders because the effects of CBRN agents and the clinical presentations of casualties at each triage stage can vary. The uniqueness of a CBRN event can render standard patient monitoring medical device and conventional triage algorithms ineffective. Despite the challenges, there have been recent advances in CBRN triage technology that include: novel technologies; mobile medical applications ("medical apps") for CBRN disasters; electronic triage tags, such as eTriage; diagnostic field devices, such as the Joint Biological Agent Identification System; and decision support systems, such as the Chemical Hazards Emergency Medical Management Intelligent Syndromes Tool (CHEMM-IST). Further research and medical device validation can help to advance prehospital triage technology for CBRN events.

Emergency preparedness in obstetrics.

During and after disasters, focus is directed toward meeting the immediate needs of the general population. As a result, the routine health care and the special needs of some vulnerable populations such as pregnant and postpartum women may be overlooked within a resource-limited setting. In the event of hazards such as natural disasters, manmade disasters, and terrorism, knowledge of emergency preparedness strategies is imperative for the pregnant woman and her family, obstetric providers, and hospitals. Individualized plans for the pregnant woman and her family should include knowledge of shelter in place, birth at home, and evacuation. Obstetric providers need to have a personal disaster plan in place that accounts for work responsibilities in case of an emergency and business continuity strategies to continue to provide care to their communities. Hospitals should have a comprehensive emergency preparedness program utilizing an "all hazards" approach to meet the needs of pregnant and postpartum women and other vulnerable populations during disasters. With lessons learned in recent tragedies such as Hurricane Katrina in mind, we hope this review will stimulate emergency preparedness discussions and actions among obstetric providers and attenuate adverse outcomes related to catastrophes in the future.
