Teaching on the run tips 5: teaching a skill

Junior doctors need to have the skills to competently perform a wide range of procedures, and inability to do so is an important stressor for a new doctor.1 Skills may range from carrying out practical tasks (intravenous cannulation), to examining patients (cranial nerve examination), to communicating well (breaking bad news). Teachers rated practical skills teaching 11th in a list of educational themes they felt they needed instruction on, whereas junior medical officers ranked it 5th, suggesting that we don’t teach as well as we think we do.2

Simulated patients, videos, manikins, computers and virtual reality technology are increasingly being used to ensure that trainees learn skills in a safe environment, receive feedback, and reach a certain level of competence before they use the skills on patients.3

The first trainee year is critical for learning many of these skills.4 Skills centres are playing an increasing role these days, but the challenge is to make sure that laboratory-learnt skills are safely implemented in the workplace. Abundant opportunities arise during work that learners are eager to be involved with. As practising clinicians, part of our teaching role is to decide whether junior staff can safely carry out procedures on patients under our care.

Skills require more than performing tasks. They include:

• Knowledge (indications, contraindications, complications and their prevention);

• Skill (preparation, technique, dexterity); and

• Communication (consent, comfort and dignity of patients; realising when to get help).

How are skills learned on the job? The “see one, do one, teach one” approach is limited, often failing to teach the skill properly or to check whether the trainee can perform the skill.

One way of teaching skills, suggested by Rodney Peyton of the Royal College of Surgeons,5 uses four steps:

• Demonstration. Trainer demonstrates at normal speed, without commentary.

• Deconstruction. Trainer demonstrates while describing steps.

• Comprehension. Trainer demonstrates while learner describes steps.

• Performance. Learner demonstrates while learner describes steps.

This four-step approach ensures that the teacher breaks the process into manageable steps, asks the learner to vocalise the steps, and provides repetition to reinforce the learning and correct mistakes.

By following the four-step approach, the trainee has shifted from being “consciously incompetent” (realising they can’t do it) to being “consciously competent” (being able to do it with great thought) (Box). Only with repeated practice will he or she be able to perform satisfactorily in a variety of situations.
