In 2019, nearly half of all hospital contacts in Belgium took place through the emergency department, and more than a third of patients arrived after an accident or trauma. In instances of overcrowding, patients with minor orthopedic injuries face prolonged waiting times. Previous studies have shown that implementing triage protocols for medical imaging conducted by a triage nurse can reduce the Total Length of Stay (TLOS) for this patient group.

This is a single-center, unblinded, randomized, controlled trial that aims to evaluate the impact of a nurse triage protocol on turnaround time (primary outcome), quality of care, and patient satisfaction. The study population consists of adults who present with minor orthopedic injuries below the elbow or knee and have an Emergency Severity Index (ESI) of 4 or 5. Participants are randomly assigned to either the 'nurse triage protocol' group (n=110) or the 'usual care' group (n=110).

Inclusion Criteria:

• Adults (18 years old)
• ESI 4 or ESI 5 Recent trauma (< 10 days after trauma)
• Accidental trauma mechanism
• Trauma below the elbow (forearm, wrist, hand, finger)
• Trauma below the knee (lower leg, ankle, foot, toe)

Exclusion Criteria:

• ESI 1 or ESI 2 or ESI 3
• Return visit after previous emergency department contact for the same injury (e.g. increased pain, tight cast, ...)
• Trauma resulting from underlying somatic pathology (e.g. syncope, epileptic attack, vertigo, vasovagal collapse, ...)
• Atraumatic (pain) complaints (e.g. pain in the calf, toe, foot, wrist, ... without a clear trauma mechanism)
• Additional, non-orthopedic injuries (e.g. laceration, signs of cerebral commotion, ...)
• Pregnancy or a suspicion of pregnancy
