Brief Summary

Ultrasound-guided regional anesthesia/analgesia techniques (or simply, 'regional blocks') have gained popularity as they can reduce, and sometimes even eliminate, the need for opiate analgesics (and, consequently, their side effects), thereby improving patient safety, reducing length of hospital stay and medical costs, and improving patient satisfaction. However, a major barrier to mainstream uptake of such techniques relates to training. These techniques require the acquisition of new skills under expert guidance, which is often not possible given the daily demands placed upon anesthesiologists. As a result, many opportunities for providing regional blocks may be missed. The purpose of this study is to implement a new real-time 'near remote' guidance method in which trainees who are to perform regional blocks can do so via tele-mentoring under expert guidance. This will be done using a novel technology whereby the ultrasound image is concurrently displayed on an iPad screen (for the block operator/trainee) as well as on the (near remotely supervising) expert mentor's smartphone. Trainees and mentors will use this method to perform various standard of care regional blocks, either in the perioperative or emergency department settings. Participants' opinions of the novel teaching and learning method will be assessed.

Outcome Measures

Primary Outcomes (1)

  • Participant opinion

    The investigators will assess the opinions of mentors and trainees regarding the use of 'near-remote' guidance for the performance of ultrasound-guided regional blocks.

    Immediately following block performance

Secondary Outcomes (6)

  • Block success

    Within 30 min following block performance

  • Block image

    Through study completion, an average of 1 year

  • Complications

    Immediately postoperatively

  • Patient satisfaction

    Immediately postoperatively

  • Number of attempts

    Immediately following block performance

  • +1 more secondary outcomes

Interventions

Trainees who are to perform regional blocks will do so under expert guidance via tele-mentoring. This will be done using a novel technology consisting of a wirelessly linked iPad which will display the ultrasound image to the block operator/trainee. This image will be concurrently visualized by an expert mentor through their smartphone, who will then provide feedback/guidance in real-time to the operator/trainee.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Participants will include: (1) mentors, i.e., staff regional anesthesiologists who are experts in ultrasound-guided regional blocks; (2) trainees, i.e., PGY-3 to PGY-5 anesthesia and emergency medicine residents, and emergency medicine staff physicians; and (3) patients, i.e., individuals 18 years and older scheduled for surgery amenable to regional blocks or presenting to the emergency department with traumatic injuries amenable to regional blocks.

You may qualify if:

  • Mentors: Staff anesthesiologists who are experts in regional blocks.
  • Trainees: Senior (PGY3-5) residents (anesthesiology and emergency medicine), and staff (emergency medicine) physicians who have already performed and are comfortable with being supervised near remotely for the regional block at hand.
  • Patients: Greater or equal to 18 years of age presenting for surgery or with traumatic injuries amenable to regional blocks.
  • All of the above: Able to read and understand English, and competent to provide written informed consent.

You may not qualify if:

  • Mentors: Staff anesthesiologists who are not experts in the performance/teaching of regional blocks.
  • Trainees: Junior (PGY1-2) residents (for any/all types of regional blocks), and senior (PGY3-5) residents and staff physicians who are not comfortable with being supervised near remotely for the regional block at hand.
  • Patients: Less than 18 years of age.
  • All of the above: Unable to read and understand English, and not competent to provide written informed consent.

The information which will be associated (via study ID number) with each ultrasound image includes: sex, age, BMI range, surgery type and regional block type. The data will be saved directly to a secure server, and subsequently exported to SPSS for analysis. The only identifier will be the study ID number.
