Next-of-kin (NOK) availability for trauma patients is crucial for consent. One-third of major trauma patients lacked NOK contact within two hours, impacting time-sensitive research enrollment.

Area of Science:

  • Emergency Medicine
  • Trauma Care
  • Clinical Research Ethics

Background:

  • Timely proxy consent is vital for enrolling major trauma patients in clinical trials.
  • Understanding next-of-kin (NOK) availability is essential for research protocol feasibility.

Purpose of the Study:

  • To determine the availability of NOK for proxy consent in major trauma patients within 24 hours of arrival.
  • To assess the impact of NOK contact time on clinical trial enrollment.

Main Methods:

  • Prospective, observational study design.
  • Inclusion of consecutive major trauma patients over a three-month period.
  • Survival analysis to calculate NOK contact probability within 24 hours.

Main Results:

  • NOK were contacted in 92% of 382 subjects.
  • Probability of NOK contact at 2, 6, and 24 hours was 68%, 80%, and 87%, respectively.
  • Median time to NOK contact was 40 minutes.

Conclusions:

  • A significant proportion of trauma patients (one-third) lacked NOK availability within two hours of arrival.
  • Time to NOK contact poses a challenge for time-critical research protocols.
  • Further research is needed to confirm generalizability and consistency of these findings.
