Objective:

To estimate the cost-effectiveness of cardiopulmonary resuscitation using an automated external defibrillator (AED) compared with basic cardiopulmonary resuscitation, for the resuscitation of unconscious patients in crowded public spaces in Colombia.

Methods:

A decision tree was designed in order to estimate the costs and outcomes of the two alternatives. This included the main outcomes after the loss of consciousness and resuscitation by any of the two alternatives. The perspective of the Colombian Health System was adopted in a time scale consisting of the time of loss of consciousness until hospital admission. The probabilities of the events were obtained from a meta-analysis of clinical trials, and the information on costs from official sources and direct consultations with AED providers in Colombia. The costs were expressed in Colombian pesos of 2016, and the effectiveness in deaths prevented. Deterministic and probabilistic sensitivity analyses were performed to estimate the impact of uncertainty on the conclusions.

Results:

The cost-effectiveness of cardiopulmonary resuscitation with AED was COP $3,267,777 per death avoided. The probability that this intervention would be cost-effective is greater than 90% for cost-effectiveness threshold greater than 10 million Colombian pesos.

Conclusion:

A cardiopulmonary resuscitation program with early defibrillation using an AED in crowded public spaces is a cost-effective alternative for the Colombian Health System.
