Most Frequent Emergency Department Visits in 2018

Introduction

Emergency departments (EDs) across the United States serve as critical healthcare safety nets, providing round-the-clock medical care for acute illnesses and injuries. In 2018, emergency rooms nationwide saw approximately 145 million visits, many of which were for conditions that could potentially be prevented or managed in alternative healthcare settings. Understanding the most common reasons for emergency department visits helps healthcare systems optimize resources, develop preventive strategies, and improve patient outcomes.

1. Abdominal Pain

Abdominal pain consistently ranked as the leading reason for emergency department visits in 2018, accounting for approximately 7.5% of all ED visits. This broad category encompassed diverse conditions ranging from appendicitis, gallbladder disease, and kidney stones to gastrointestinal infections and gynecological issues. The complexity of abdominal presentations often necessitates comprehensive evaluations, including physical examinations, laboratory testing, and imaging studies to determine underlying causes and appropriate treatment plans.

2. Chest Pain

Chest pain represented nearly 5.5% of emergency department visits in 2018. This symptom often raises significant concern as it can indicate serious cardiac conditions including myocardial infarction. While many patients presenting with chest pain experienced non-threatening issues such as acid reflux, anxiety, or musculoskeletal strain, emergency physicians must rule out life-threatening conditions through electrocardiograms, cardiac enzyme testing, and sometimes observation periods. This systematic approach ensures that patients with cardiac emergencies receive timely intervention.

3. Respiratory Distress

Respiratory complaints, including shortness of breath and difficulty breathing, accounted for approximately 4.5% of ED visits in 2018. These visits frequently involved patients with asthma exacerbations, chronic obstructive pulmonary disease (COPD) flare-ups, pneumonia, and bronchitis. Environmental factors, seasonal variations, and influenza outbreaks contributed to these numbers, with significant peaks observed during winter months when respiratory viruses circulated more widely. Treatment typically involved bronchodilators, steroids, supplemental oxygen, and sometimes respiratory support.

4. Fever

Fever, particularly in pediatric patients, represented approximately 4.2% of emergency department visits. Parents often sought emergency care for children with elevated temperatures, especially when accompanied by concerning symptoms such as lethargy, poor feeding, or dehydration. While most fever-related visits resulted from viral infections that resolve without specific treatment, emergency clinicians carefully evaluated each case to identify potentially serious bacterial infections requiring antibiotic therapy or more intensive intervention.

5. Cough and Upper Respiratory Symptoms

Cough and cold symptoms accounted for approximately 3.8% of emergency department visits in 2018. Many patients seeking care for these relatively common symptoms lacked appropriate access to primary care providers or needed after-hours care when their regular physicians were unavailable. The majority of these visits resulted in symptomatic treatment and discharge home, highlighting potential opportunities for alternative care settings and better patient education about managing common respiratory illnesses.

6. Injuries from Falls

Fall-related injuries represented a significant portion of ED visits in 2018, particularly among elderly populations. These injuries ranged from minor contusions and sprains to serious fractures, hip injuries, and traumatic brain injuries. The aging demographic contributed to increasing numbers of fall-related visits, with many involving patients taking anticoagulant medications, which complicated management due to increased bleeding risks. Prevention programs and home safety assessments could potentially reduce these visits.

7. Back Pain

Back pain accounted for approximately 3.2% of emergency department visits in 2018. While most back pain cases are musculoskeletal in nature and don't require emergency intervention, patients often sought ED care due to severe pain intensity, limited mobility, or concerns about more serious underlying conditions. Treatment typically involved pain medication, muscle relaxants, anti-inflammatory medications, and referrals to appropriate outpatient specialists for ongoing management and physical therapy.

8. Headache

Headache complaints represented approximately 2.8% of ED visits in 2018, with migraines being a common diagnosis. Patients frequently sought emergency care when their usual headache treatments proved ineffective or when experiencing unusually severe pain described as "the worst headache of their life" a concerning symptom potentially indicating subarachnoid hemorrhage. Headaches secondary to other conditions like meningitis, temporal arteritis, or hypertensive crises were also evaluated thoroughly in the emergency setting.

9. Urinary Tract Infections

Urinary tract infections (UTIs) accounted for approximately 2.5% of emergency department visits in 2018. Women were disproportionately affected, with many seeking care for classic UTI symptoms including dysuria, frequency, urgency, and suprapubic discomfort. While UTIs can often be managed in outpatient settings, patients sometimes sought ED care when experiencing severe symptoms, were unable to obtain timely appointments with primary care providers, or when experiencing concerning symptoms like flank pain suggesting possible kidney infections (pyelonephritis).

10. Skin and Soft Tissue Infections

Cellulitis, abscesses, and other skin infections accounted for approximately 2.3% of emergency department visits in 2018. The continued prevalence of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) contributed significantly to this category. Many patients required incision and drainage procedures and prescription of appropriate antibiotics based on likely pathogens and local resistance patterns. These visits increased during warmer months when minor skin injuries provided entry points for bacterial infections.

11. Abdominal Cramps and Pain

Distinct from general abdominal pain, specifically reported abdominal cramps accounted for approximately 2.1% of emergency department visits. These frequently related to gastrointestinal conditions including gastroenteritis, irritable bowel syndrome, inflammatory bowel disease exacerbations, and menstrual-related pain. Management strategies varied based on underlying causes, with treatments including hydration, antiemetics, antispasmodics, and hormonal therapies.

12. Superficial Injuries and Contusions

Superficial injuries and contusions represented approximately 2% of emergency department visits in 2018. These minor injuries typically resulted from falls, sports activities, or accidents and didn't involve fractures or internal organ damage. Many patients sought emergency care despite these relatively minor injuries due to limited access to alternative care settings or concerns about more serious underlying conditions that might not be immediately apparent.

Demographic Patterns

Emergency department visit patterns in 2018 demonstrated notable demographic variations:

• Children under 15 and adults aged 65 and older had the highest ED visit rates
• Female patients generally utilized emergency departments more frequently than males
• Medicaid recipients and uninsured patients had higher ED utilization rates compared to those with private insurance
• Urban hospitals saw higher volumes of emergency visits compared to rural facilities
• Weekend visits increased approximately 15-20% compared to weekdays

Implications for Healthcare Delivery

The patterns of emergency department utilization in 2018 reveal that while trauma and acute life-threatening conditions represent important components of emergency care, a significant proportion of visits relate to conditions that might be preventable or better managed in alternative care settings. These findings suggest important opportunities for healthcare system improvements including:

• Expanded primary care availability and after-hours options
• Better patient education about managing common illnesses and injuries
• Development of urgent care centers for conditions requiring prompt but not emergent intervention
• Improved chronic disease management to reduce exacerbations requiring emergency care
• Integration of telemedicine for appropriate initial assessments

Conclusion

Emergency departments remain essential components of the United States healthcare system, serving as critical access points for acute medical care. The patterns observed in 2018 data highlight both the appropriate utilization of these facilities for genuine emergencies as well as opportunities to improve care delivery models. For healthcare providers and policymakers, understanding these utilization patterns helps inform decisions about resource allocation, preventive health measures, and strategies to reduce unnecessary ED visits while ensuring that patients with genuine emergencies continue to receive timely, appropriate care.
