Augmented Reality as Discharge Information for Hospitalized Cardiology Patients (RACAR)

February 2, 2026 updated by: Hospital Universitario Getafe

Implementation of an Augmented Reality System to Complement Discharge Information in Hospitalized Cardiology Patients

The goal of this clinical trial is to find out whether a simple augmented reality tool provided at hospital discharge can improve patients' understanding of their care, adherence to treatment, and health outcomes, compared with the usual discharge information.

This study includes adult patients who are admitted to a cardiology department because of:

  • Ischaemic heart disease
  • Atrial fibrillation
  • Heart failure
  • Or who need a pacemaker implantation

The main questions this study aims to answer are:

  • Does providing augmented reality information at discharge improve patients' perceived quality of care?
  • Does it improve patients' adherence to their prescribed treatment?
  • Does it reduce major cardiovascular events such as hospital readmission, heart attack, stroke, or cardiovascular death?

Researchers will compare two groups of participants:

  • A control group, who will receive the usual medical discharge report.
  • An intervention group, who will receive the usual medical discharge report plus an information card with a drawing and a QR code that gives access to an augmented reality application.

Participants will:

  • Receive their discharge information according to the group they are assigned to.
  • Use the augmented reality application if they are in the intervention group.
  • Be followed over time to assess treatment adherence, patient experience, and cardiovascular events.

This is a low-intervention, randomized, single-centre clinical trial conducted in Getafe, Madrid, Spain. Participation in this study does not involve taking any additional medication.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Intervention Group
This group receives the usual medical discharge report plus an information card with a drawing and a QR code that gives access to an augmented reality application explaining their disease.
Device: Augmented reality app

The card provided in addition to the usual medical discharge report is designed with a simple drawing that identifies each condition and a QR code.

This code can be scanned from any mobile device using the device's camera. Once scanned, a 3D model of a heart or a stent (depending on the condition) appears on the device, showing movement, vibration, and sound as an example of augmented reality.

The user can also access simple options through three buttons:

  1. Video recorded by a cardiology professional: a brief and easy-to-understand explanation of the patient's condition, lasting approximately 2-3 minutes, provided by a hospital cardiology professional.
  2. Treatment recommendations: a drop-down section with a table of discharge recommendations for the patient's condition, including lifestyle and dietary advice.
  3. Warning signs: situations that the patient should pay attention to and seek medical advice if they occur.
No Intervention: Control group
This group receives the usual medical discharge report.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
PRIMARY OUTCOME: PREM and treatment adherence at one and six months
Time Frame: Follow up at one and six months from enrollment
To assess PREM (Patient-Reported Experience Measures) in the intervention group and in the control group at discharge and at follow-up.
Follow up at one and six months from enrollment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
MACE at one and six months
Time Frame: From enrollment at one and six months
Data on major adverse cardiovascular events (MACE) will also be collected at one and six months from discharge in both groups. MACE include heart attack, stroke, cardiovascular-related hospital readmission, and cardiovascular death.
From enrollment at one and six months
