Emergency Care Capacity and Quality

This measure's main objectives are to capture variation in emergency care and measure capacity and quality of emergency care to support hospital quality improvement. The measure aims to reduce patient harm and improve outcomes for patients requiring emergency care in an emergency department (ED). Emergency care capacity is inclusive of several concepts pertaining to boarding and crowding in an ED. This measure will be designed to align with incentives to promote improved care both in EDs and the broader health system to help identify where patients do not receive appropriate or timely access to emergency care.

The measure intends to capture established outcome metrics that quantify capacity and access of care in an ED, including for patients with mental health diagnoses. Additional disparities in ED care are well documented for patients of older age, by race and ethnicity, primary language, and insurance status; such documented disparities include significantly longer ED wait times, higher left without being seen rates, longer boarding times, and longer total length of stay in the ED.

The measure will utilize volume standardization to address differences in patient population between hospitals. Volume-standardization is harmonized with other existing measures and accommodates a “like to like” comparison among hospitals. Large volume EDs will always be compared to large volume EDs, while smaller volume EDs will always be compared to EDs of similar size. We will collect other demographic data to explore score variation by various social and demographic risk factors.

This measure aims to reduce patient harm and improve outcomes for patients requiring emergency care in an ED by addressing the variation in emergency care and measuring the capacity and quality of emergency care. There are long-standing concerns about parameters that impact the quality and timeliness of care in the ED. Currently, there are no national metrics to assess the proportion of patients impacted by the quality of timely ED care.

The goal of this Emergency Care Capacity and Quality (ECCQ) measure is to assess and improve the safety of the 140 million ED visits that patients experience each year. Limitations in capacity and quality of emergency care have been shown to be associated with harm, such as increases in mortality, delays in care, preventable errors, poor patient experience and staff burnout. These capacity and quality limitations are also associated with increased costs of care. This proposed ECCQ measure, still in development, is intended for use in CMS’s HOQR program. The numerator is comprised of all ED visits that meet the criteria, defined in the numerator, of a quality gap in access. Challenges related to emergency care access and capacity have been increasing and have prompted public calls for action. Prior efforts to measure components of this proposed measure (for example, ED boarding, through use of the ED-2 measure) were unsuccessful, likely in part due to the construction of the measure score, which was based on median performance that obscured poor performance. Implementation of this proposed measure, which captures multiple components of quality and capacity, will minimize gaming, and help identify facilities where patients do not receive appropriate or timely access to emergency care. This measure, therefore, could positively impact millions of patients who seek treatment in the ED and help address long-standing disparities in emergency care, including for patients with mental health diagnoses.

Improvement noted as a decrease in measure score (decrease in proportion of eligible visits that meet the numerator criteria).

Boarding:
The practice of holding patients in the emergency department after they have been admitted to the hospital because no inpatient beds are available.

ED Observation:
ED observation stays, defined as an observation encounter where the patient remains physically in an area under control of the emergency department and under the care of an emergency clinician inclusive of observation in a hospital bed. ED observation involves placing patients in observation status after their initial evaluation, allowing for continued assessment, treatment, and the determination of a safe disposition. ED observation stays are generally longer than routine ED visits and may allow time to evaluate a patient’s response to treatment.

Mental Health: 
Mental health generally refers to mental health diagnoses, life stressors and crises, and stress-related physical symptoms. Behavioral health care refers to the prevention, diagnosis, and treatment of those conditions. For this measure, mental health cohorts will be defined separately from substance use disorders. 

Left Without Being Seen (LWBS):
Patients arrive to the ED for evaluation and leave before seeing a physician, advanced practice nurse or physician’s assistant.

Measure Score Calculation
The measure score is first calculated at the individual ED level as the proportion of ED visits where any one of the four outcomes occurred. Scores will be standardized z-scores by ED case volume strata (defined in ED visit volume bands of 20,000 visits). For CMS Certification Numbers (CCNs) with more than one ED, volume-adjusted z-scores are then combined as a weighted average for that CCN. A z-score of greater than zero means worse performance and less than zero means better performance, compared to like EDs.

For the purposes of this measure, a decision to admit can be captured using any of the following: 
  - a decision to admit order to admit the patient inpatient 
  - an evaluation that results in a decision to admit
  - an order to admit to inpatient
  - an order for a bed assignment
  - start of inpatient admission

This eCQM is an episode-based measure. An episode is defined as an ED visit that ends during the measurement period. 

This version of the eCQM uses QDM version 5.6. Please refer to the eCQI Resource Center (https://ecqi.healthit.gov/qdm) for more information on the QDM.

The numerator is comprised of ED visits meeting the denominator criteria and where the patient experiences any of the following quality gaps in access:
1. The patient waited longer than 60 minutes (1 hour) after arrival to the ED to be placed in a treatment room or dedicated treatment area that allows for audiovisual privacy during history-taking and physical examination, or 
2. The patient left the ED without being evaluated, or  
3. The patient boarded (time from Decision to Admit order to ED departure for admitted patients) in the ED for longer than 240 minutes (4 hours), or
4. The patient had an ED length of stay (LOS) (time from ED arrival to ED departure as defined by the ED departure timestamp indicating when the patient physically left the ED) of longer than 480 minutes (8 hours).

ED encounters with ED observation stays are excluded from criteria #3 (boarding) and #4 (ED LOS). To clarify, patients who have a ‘decision to admit’ after an ED observation stay remain excluded from criteria #3 (boarded) calculations.
