Details and patient eligibility

About

TIGER is a multicentre, 2-arm, parallel group, assessor blinded, non-inferiority randomised controlled trial with an internal pilot to assess if non-surgeon physicians (NSPs) can effectively perform mesh inguinal hernia repair compared to fully trained surgeons in adult patients with non-complicated inguinal hernia.

Full description

Adult patients (18 years old to 60 years old, men and women) with non-complicated inguinal hernias suitable for elective repair will be recruited from at least 18 representative district hospitals in Low- and Middle-Income countries. Before and during a district hospital visit by a senior surgeon (at least once a year), a call will be made to the community, as is current practice (e.g., leaflet, radio, verbal at mosques, churches, market places, etc.).

Patients will attend the local district hospital on specific dates, which are contained within the announcement. A fully trained surgeon will examine the patient and identify patients according to the eligibility criteria, and if confirmed as eligible, they will be invited to enter the trial and consent obtained. If patients are not eligible for the trial, their care will follow the usual pathways.

After patient eligibility has been confirmed and informed consent has been obtained, patients will be randomised into the TIGER trial by a member of the TIGER research team at the site. Patients will be randomised to an operating list: NSP or surgeon list. The operating lists will be performed at the same hospital where the patient is randomised.

Patients are randomised to either of the following:

Intervention: Mesh inguinal hernia repair performed by Non-Surgeon Physicians (NSP) through an accredited training programme prior to commencing participation in the study.

Control: Mesh inguinal hernia repair performed by fully trained surgeons, recognised by the Ghana College of Surgeons and Physicians and other recognised Surgical Colleges around the globe.

A 'random element' will be included in the minimisation algorithm, so that each patient has a probability (unspecified here) of being randomised to a different intervention that they would have otherwise received.

Sample size: A sample size of 1782 patients (891 patients per arm) will be required to detect a non-inferiority margin of 2.5% in safe surgery, assuming a 90% baseline rate of safe surgery in the control arm (i.e., 10% of the patients are expected to have SSI or reoperation or recurrence in the control group). This allows for a 15% loss to follow-up, death before the primary outcome assessment, and misdiagnosis of inguinal hernia.

Inclusion Criteria

  • Patients older than 18 years (male or female) and less or equal to 60 years (this criteria will be made country-specific. Each country will decide the lower and upper age limit for the trial),
  • Primary inguinal hernia (unilateral) eligible for elective inguinal hernia repair
  • Primary bilateral, but only one side being repaired
  • Written informed consent of patient (signature or a fingerprint)

Exclusion Criteria

  • Complex inguinal hernias: recurrent, obstructive, or femoral hernias
  • Bilateral inguinal hernias undergoing simultaneous repair
  • Inguinal hernias needing emergent surgical repair (e.g., incarcerated)
  • Patient unable to complete post-operative follow-up

1,782 participants in 2 patient groups, including a placebo group

Non-Surgeon Physician
Experimental group
Description:
The intervention arm is a mesh inguinal hernia repair performed by a non-surgeon physician (NSP). These are medical officers who have finished a 2-year mandatory house job. The medical officers will be trained to perform inguinal hernia repair by a certified surgical trainer in Ghana.
Treatment:
Other: Mesh inguinal hernia repair performed by Non-Surgeon Physicians (NSP)
Control: Surgeon
Placebo Comparator group
Description:
The control is a mesh inguinal hernia repair performed by a fully trained surgeon, defined as one who is accredited as fully trained with the Ghana College of Physicians and Surgeons, West African College of Surgeons, or equivalent. A trained surgeon will be assisted by an NSP who has completed the TIGER training programme. We anticipate that at least 5-10 fully trained surgeons will take part in the control arm.
Treatment:
Other: Mesh inguinal hernia repair performed by fully trained surgeons
