NCAA Dataset overview

In NCAA, we audit cardiac arrests attended to by in-hospital resuscitation teams.

A clearly defined data collection scope is essential for all hospitals to collect consistent and comparable data. Data are collected where:

  • patient is an adult or child over 28 days old;
  • patient receives chest compression(s) and/or defibrillation;
  • a 2222 call is made; and
  • patient is attended to by hospital-based resuscitation team (or equivalent) in response to a 2222 call.
We are currently collecting a small set of key fields (Level A) to provide us with good quality data on in-hospital cardiac arrests. These cover details about the patient, their hospital admission, the cardiac arrest, and short-term outcome.

Predicted survival

Data are used to predict survival both to the end of the team visit and to hospital discharge. These predictions can then be compared to the actual outcome for each cardiac arrest. See the NCAA Reports page and the NCAA risk models document (under Related files) for further details on risk-adjusted data analysis.

The future

The flexibility of our secure online system allows us to add additional data collection fields as required. In the short-term this allows us to add some key research questions to NCAA data collection.

In the longer-term, we have established NCAA with a modular dataset structure. Hospitals able to collect the current dataset (Level A) will be given the option to expand their data collection thus providing them with more complex analyses. The dataset will increase in complexity through Level B and Level C, beginning to look at areas such as the interventions used during the arrest and longer-term outcomes.
