NCT04743765

Brief Summary

The HIP ATTACK-2 trial is a multicentre, international, parallel group randomized controlled trial to determine whether accelerated surgery for hip fracture in patients with acute myocardial injury is superior to standard care in reducing death at 90 days after randomization. The trial will also assess secondary outcomes at 90 days after randomization: inability to independently walk 3 metres, time to first mobilization (first standing and first full weight bear), composite and individual assessment of major complications (e.g., mortality, non-fatal myocardial infarction, acute congestive heart failure, and stroke), delirium, length of stay, pain, and quality of life.

Eligibility Criteria

Age45 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • age ≥45 years;
  • diagnosis of hip fracture during working hours with a low-energy mechanism requiring surgery;
  • troponin elevation ( at least one troponin measurement above the upper limit of normal occurring from the time of hip fracture to the time of randomization); and
  • informed consent.

You may not qualify if:

  • taking a therapeutic dose of an anticoagulant for which no reversing agent is available and the anesthesiologist or surgeon believe surgery within 6 hours of eligibility criteria met would not be safe;
  • patients on a therapeutic vitamin K antagonist with a history of heparin induced thrombocytopenia (HIT);
  • patients with peri-prosthetic fracture, open fracture or bilateral fractures;
  • patients requiring an emergency surgery for another reason (e.g., subdural hematoma);
  • patients with acute myocardial infarction deemed to be clinically unstable, with a mechanical complication (i.e., acute papillary muscle rupture, ventricular septal defect), ST elevation myocardial infarction, or cardiogenic shock;
  • patients refusing consent; or
  • patients previously enrolled in HIP ATTACK-2.

Data Sharing

IPD Sharing
Will not share

The Population Health Research Institute (PHRI) is the sponsor of this trial. The PHRI believes the dissemination of clinical research results is vital and sharing of data is important. PHRI prioritizes access to data analyses to researchers who have worked on the trial for a significant duration, have played substantial roles, and have participated in raising the funds to conduct the trial. PHRI balances the length of the research study, and the intellectual and financial investments that made it possible with the need to allow wider access to the data collected. Data will be disclosed only upon request and approval of the proposed use of the data by a Review Committee.
