A New Crowding Indicator in the Emergency Department

An observational study in Emergency Department and Crowding, sponsored by Mario Negri Institute for Pharmacological Research. Active, not recruiting at 52 sites in Italy. Per ClinicalTrials.gov, last updated 2026-05-20.

Why
  1. Emergencies describes something many studies share rather than a condition a study is about.
  2. The study's listed conditions name Crowding.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

Fenice has proposed a new indicator to measure the level of crowding in the ER. The aim of this study is to evaluate, in a national multicenter context, the degree of agreement between the Fenice indicator and the perception of crowding of the ER operators and to compare this agreement with that between NEDOCS and the perception of the operators.

Read the detailed description

The NEDOCS (National Emergency Department OverCrowding Study) is currently the most widely used indicator in Italy to measure the level of crowding in Emergency Departments (EDs). However, despite its widespread use, it presents several critical issues. First of all, it was developed in a context very different from the current Italian one, since it was built on data collected in 2002 in 8 medium-large US university EDs. It is therefore not possible to take for granted that this indicator can accurately describe the current crowding conditions of Italian EDs. Furthermore, the factors that make up the NEDOCS are often calculated differently by the various hospital facilities, compromising the comparability of the estimates.

Fenice has proposed a new indicator to measure the level of crowding in EDs. The indicator was developed to measure one of the objective consequences of crowding in EDs, namely the increase in waiting time for patients with a problem classified as minor urgency or deferrable to triage (codes 3 and 4). In parallel, the Fenice study has shown that NEDOCS is not very sensitive to this objective consequence of crowding.

The aim of this study is to evaluate, in a national multicenter context, the degree of agreement between the Fenice indicator and the perception of crowding of the operators of the ER and to compare this agreement with that between NEDOCS and the perception of the operators.

Lead sponsor

Mario Negri Institute for Pharmacological Research is the lead sponsor of 160 studies on the registry; 37 are open to participants now.

Compared within Crowding, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Emergencies. The counts are of registry records indexed under each term, refreshed daily. How we classify →

What researchers measure

Primary outcomes

  1. Proportion of variation in the ED staff perceived crowding level that is explained by the Fenice crowding score.

    The outcome will be measured using the coefficient of determination (referred to as R2) of the linear model regressing the perceived level of crowding on the Fenice score.

    Time frame: September 2025 - December 2025

Secondary outcomes

  1. Proportion of variation in the ED staff perceived crowding level that is explained by the NEDOCS score, measured using the coefficient of determination (R2) of the linear model regressing the perceived level of crowding on the NEDOCS score.

    Time frame: September 2025 - December 2025

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 20, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
