Comparing lenient and strict arm instructions after heart device surgery

A Randomized Trial of Lenient Versus Strict Arm Instruction Post Cardiac Device Surgery - LENIENT

Phase 4 Interventional Ottawa Heart Institute Research Corporation · NCT04915261

This study tests whether allowing more movement with the arms after heart device surgery can improve recovery and reduce complications for patients.

What this trial studies

This study investigates the impact of lenient versus strict arm restrictions on patients who have undergone cardiac device surgery. It aims to determine if reducing arm restrictions can enhance patient experience and lower complication rates post-operatively. The study employs a cluster crossover randomized design to compare outcomes between the two groups, focusing on complications such as lead dislodgement and device infection. The goal is to establish standardized postoperative arm restriction recommendations across hospitals.

Who should consider this trial

Good fit: Ideal candidates include all patients undergoing surgery for the implantation of cardiac implantable electronic devices.

Not a fit: Patients undergoing standalone CIED generator replacement may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved quality of life for patients by allowing more freedom of movement after cardiac device surgery.

How similar studies have performed: Other studies have explored postoperative care protocols, but this specific comparison of lenient versus strict arm restrictions is novel.
