Topics Overview of the National Hospital Ambulatory Medical Care Survey (NHAMCS) How many children and adolescents go to the ED? Where do they go? Why do they go? What happens while in the ED? Take home messages

Characteristics of NHAMCS Survey Type of Data Years fielded Current sample size (approximate) National Hospital Ambulatory Medical Care Survey (NHAMCS) Visits to hospital emergency department (ED) and outpatient departments (OPD) 1992-present 480 hospitals 35,000 ED visits 30,000 OPD visits 3)NHAMCS-fielded annually since 1992 4)NHAMCS-surveyed 480 hospitals in 2002 5)NHAMCS has 2 components the emergency dept (ED) and outpatient dept (OPD)

NHAMCS Methodology National probability sample Non-Federal, short-stay (<30 days), general (medical/surgical, or children’s) hospitals Located in 50 states and D.C. 4 stage sample design (PSU, hospital, ED/OPD, and visits) 4 week reporting period Endorsed by SAEM, ACEP, ENA, FAH, ACOEP, and Surgeon General Scope: -Basic unit of sampling is patient visit -Emergency and outpatient departments of non-institutional general and short-stay hospitals -4 stage sampling: PSU, Hospital, ED/OPD, visits -In hospital collecting data for 4 weeks

NHAMCS Response Rates ED OPD Doesn’t disrupt workflow Hospitals are used to being surveyed Results are more about the organization than any one practitioner OPD

Data analysis Secondary analysis of ED visit records for persons <18 years of age using data from the 2003-2005 NHAMCS, last time - 1992-94. Visits by patients <18 yrs and age subgroups: <1 year, 1-4 years, 5-12 years, and 13-17 years.

How many go to the ED? 28.3 million pediatric visits annually 38.4 visits per 100 children <18 years Highest rate for black or AA infants <1 year of age (1.6 visits for each infant). Children and adolescents make up 20-30% of all the ED visits

Where do they go? Voluntary nonprofit hospitals -72% Metropolitan statistical areas (MSAs) - 85% Level 2 trauma centers - 28% Large volume EDs (>10,000 pediatric visits annually)- 52% General medicine emergency service areas (ESAs) -73% only 1:5 treated in pediatric dedicated ESAs

Likelihood of arriving to the emergency department via ambulance, by age group: United States, 2003-05 1.7 million (6%) arrive by ambulance.

Trends in the percentage of pediatric emergency department visits with payment source of Medicaid/SCHIP by patient age: United States, 1995-2005 41% had Medicaid or State Children’s Health Insurance Program (SCHIP) listed as expected source of payment; 10% had no insurance. ED visits with SCHIP has increased even though visit rates have stayed the same. Enrollment in Medicaid/SCHIP does not seem to decrease ED usage. 1 1 1 NOTE: 1p<0.05.

Why do they go?

Top 5 diagnosis groups of pediatric emergency department visits by patient age : United States, 2003-05 Viral infections1 Fever Fever Fractures Open wounds Fractures Ear and mastoid Open wounds Contusions General symptoms2 Respiratory illness3 Contusions General symptoms2 Ear and mastoid Sprains and strains General symptoms2 Respiratoryillness3 Respiratoryillness3 General symptoms2 Open wounds 1 Viral infections includes chlamydial infections. 2General symptoms includes items such as rash, heart murmur, cough, stridor, chest pain, nausea, vomiting, and pain. 3Respiratory illness includes acute sinusitis, pharyngitis, tonsillitis, and bronchiolitis.

What happens while in the ED? On average: 2.5 hrs in the ED, 49.5 minutes waiting to see a physician, 1.7 hrs being treated. 10.3% see an NP or PA, 9.2% do not see a physician <1% of visits arrive DOA, die in the ED or need resuscitation. Nonsteroidal anti-inflammatory drug (NSAID) are the most frequently prescribed therapeutic drug class - 17.6% Imaging was the most frequently used diagnostic service – 32.2%

Percent distribution of injury-related pediatric emergency department visits, presenting with moderate or severe pain by mention of pain medication, according to patient age: United States 2003-05 *Includes antipyretics

Percent distribution of pediatric emergency department visits by selected procedures: United States, 2003-05 Other includes cardiopulmonary resuscitation; endotracheal intubation; obstetrics or gynecology care; ear, nose, and throat care; nebulizer therapy; thrombolytic therapy; and nasogastric tube or gastric lavage.

Percent of pediatric emergency department visits by discharge disposition: United States, 2003-05

IOM uses NCHS data to study the future of emergency care With the introduction of the Emergency Pediatric Services and Equipment Supplement (EPSES) to the NHAMCS in 2002 and 2003, and the release of the Emergency Pediatric Preparedness in U.S. Hospitals report, there has been a growing interest in ED pediatric visit data available from the NHAMCS.

Take Home Messages NHAMCS can be used as an effective tool for monitoring trends in pediatric ED encounters. Collecting and analyzing such data can help fill in the gaps of understanding regarding the role that EDs play in health care for children. The results of this study may help policymakers model emergency medical services for children and adolescents.
