Report Scope of U.S. Emergency Department Market

Major factors expected to drive the market include increasing visits to hospital Emergency Departments (EDs) and growing availability of insurance. Furthermore, the rising prevalence of diseases, heart failure, and accidental injuries is expected to propel market growth over the forecast period. The growing number of emergency department visits is a significant factor driving market growth. According to the CDC, around 140 million visits to Emergency Departments (ED) in the U.S. in 2021. The overall ED visit rate was 43 visits per 100 people in the same year. Infants under the age of 1 year had the highest ED visit rates at 103 visits per 100 infants, while adults aged 75 and over had an ED visit rate of 66 per 100 people. A significant percentage of emergency care (about 60%) was provided outside of regular business hours (other than 8 am to 5 pm), suggesting that the lack of less expensive alternatives is a major factor contributing to the high number of ED visits.

Moreover, hospitals are incorporating new technologies and engaging in various business activities to address the rising demand for EDs and raise awareness. For instance, in August 2023, Rush University System for Health partnered with Cadence to launch an RPM pilot program for Medicare and Medicaid patients with chronic conditions such as hypertension, congestive heart failure, and type 2 diabetes. Patients are expected to use remote monitoring devices to track their vitals, which are expected to be transmitted to Cadence’s data platform & monitored by the startup’s care teams. The pilot program aims to implement RPM technology as a true population health tool and reduce costs & unnecessary healthcare use.

Market Concentration & Characteristics

The degree of innovation in the market is expected to increase gradually with the increasing adoption of digitization. An increasing number of hospitals are adopting technologically advanced tools, such as Artificial Intelligence (AI), for improved diagnosis and to expedite routine procedures, such as devising treatment plans & prescriptions. For instance, in January 2022, Novant Health and Aidoc partnered to use AI for faster treatment of patients in the emergency department. The collaboration drives leverage to Aidoc's enterprise-grade AI solutions for medical imaging to improve patient outcomes and enhance the efficiency of emergency medical services across Novant Health's 15 medical centers across three states.

Market players such as Natchitoches Regional Medical Center (NRMC), Lifepoint Health, Inc.  HCA Management Services, L.P., TH Medical (Tenet Healthcare Corporation) are engaged in merger and acquisition activities. For instance, in January 2023, Beckman Coulter Diagnostics acquired StoCastic, LLC, a prominent AI corporation that provides decision support for hospital emergency departments. StoCastic's TriageGo will be integrated into Beckman Coulter's AI-supported Clinical Decision Support portfolio, enhancing patient care through data-driven insights.

Impact of regulations is high, the Emergency Medical Treatment and Labor Act (EMTALA) of 1986 recognizes EDs as an essential part of the social safety net that provides emergency medical care to all patients, regardless of their demographic characteristics or financial ability to pay. Medicare-participating hospitals that offer emergency services are required under Section 1867 of the Social Security Act to provide a Medical Screening Examination (MSE) upon request for treatment or examination for an Emergency Medical Condition (EMC), including active labor, regardless of the patient's ability to pay.

Market players leverage the strategy of facility expansion to increase their capabilities and promote the reach of their service offerings. For instance, in July 2023, The UAB Hospital University Emergency Department is expanding its capacity to deal with unmet demand for emergency medical services in Alabama and Birmingham. The expansion plan includes temporary waiting room space and 59 new exam rooms with additional imaging facilities for emergency clinical care.

Regional expansion is a significant factor in the market, driven by new government programs and initiatives. These expansions have the potential to deliver invaluable healthcare and economic benefits, transforming regions for future generations. For instance, in November 2022, Lakeland Regional Health established a standalone emergency department in South Lakeland, which would be situated at the junction of South Florida Avenue and C.R. 540A.

U.S. Emergency Department Market By Type Insights

Hospital emergency department segment dominated the market in 2023 with a revenue share of 94.15% and is anticipated to witness the fastest growth rate during the forecast period. The growth of the segment can be attributed to the increasing number of hospitals adopting technologically advanced tools, such as Artificial Intelligence (AI), for improved diagnosis and expedited routine procedures, such as devising treatment plans & prescriptions.

The substantial increase in visits to hospital EDs and widespread availability of insurance are expected to be the primary segment drivers over the coming years. Medicaid and Medicare provide insurance for emergency health services. According to the CDC, in 2019, over 40% of ED visits by adults aged over 65 years were by ambulance, which is covered under Medicare Part B. In addition, part B Medicare covers air ambulance trips by airplane or helicopter if necessary. Part A Medicare contributes to the expenses when a patient enters the emergency room and is subsequently admitted as an inpatient. In contrast, Part B Medicare covers the costs associated with receiving care from a doctor when admission as an inpatient is not required.

The Freestanding Emergency Department (FSED) segment is highly influenced by the overcrowding of EDs at hospitals, the increasing number of patients opting for direct treatment options, and advanced healthcare infrastructure in the country. Moreover, increasing number of injuries due to accidents and the rising incidence of chest pain, epilepsy, stroke, and other diseases requiring immediate attention are expected to drive the need for freestanding emergency departments in the country.

Common medical services include treatment for stomach & abdominal pain, fever, headache, cough, back symptoms, shortness of breath, unspecified pain, throat symptoms, & vomiting. The growth of the segment can be attributed to increasing utilization of data-driven technologies, rising patient footfall in EDs, and growing adoption of Emergency Department Information Systems (EDIS).

Furthermore, the imaging services segment is expected to witness the fastest growth rate during the forecast period. The segment is experiencing growth due to increased awareness of medical screening to assess the urgency of medical conditions, the prevalence of chronic yet manageable diseases, and the availability of ample economic resources. The majority of EDs offer basic imaging services, such as X-ray, ultrasound, and CT. FSEDs are either large facilities serving as many as 100 patients per day or small facilities serving 20 or fewer patients per day. Larger FSEDs can also offer MRI and primary care.

Furthermore, technological advancements and new product launches by companies are expected to drive the segment during the forecast period. For instance, in October 2023, Philips introduced its Point-of-care Ultrasound (POCUS) innovations at the 2023 American College of Emergency Physicians Scientific Assembly in Philadelphia, U.S. POCUS technology provides physicians with immediate insight into a patient's condition, expediting care and providing bedside treatment in various emergency care settings.
