Everything above makes the case that communication, confidence and wellbeing shape clinical outcomes. That still leaves a reasonable question: does coaching move any of it? It is a fair thing to ask before spending a training budget. Here is what the research says, including the studies that used control groups.
In a randomised controlled trial across 26 institutions, women doctors in training who took part in a four-month online group coaching programme showed significant reductions in every measure of burnout, alongside moral injury and impostor feelings, and significant improvements in self-compassion and flourishing, compared with a control group. Online. Group-delivered. Time-limited.

Employees were randomly assigned to coaching, to training, or to nothing. Only the coaching group showed a sustained reduction in impostor phenomenon scores. The training helped in the moment; the coaching held. This was the first controlled evidence that impostor feelings respond to coaching specifically, and it is worth knowing if you have people on your team quietly convinced they are about to be found out.

Doctors randomised to professional coaching saw emotional exhaustion fall while it rose in the control group, with absolute rates of high emotional exhaustion dropping 19.5% in the coached group and rising 9.8% in the controls. Overall burnout fell 17.1% and rose 4.9% respectively. That was six one-hour sessions over five months.

A meta-analysis of coaching in organisational settings found significant positive effects across all five outcome categories measured, from coping through to goal-directed self-regulation. A later meta-analysis focused exclusively on workplace coaching found the same direction of travel, with the largest effects on affective outcomes and individual-level results. Notably, it found no difference in effect between face-to-face and online delivery.

On the commercial side, a global study conducted by PricewaterhouseCoopers found a median return of seven times the initial investment for companies using coaching, with 86% of those able to calculate it reporting they at least made their money back. Separately, Deloitte's UK modelling puts the return on workplace mental health investment at around £4.70 for every £1 spent, and finds that proactive, culture-level approaches return considerably more than reactive support offered once someone is already struggling.

Two things are worth drawing out. The effects hold when coaching is delivered online and in groups, which is how most veterinary teams can realistically access it. And the returns are consistently better when support arrives before someone is in crisis rather than after. Prevention is not only kinder. It is cheaper.
