PAs, if effectively regulated and well managed, could be a great asset to the health service.
The ones I know are dedicated, well trained, clear about their role and extremely trustworthy.
Yes, we need to make sure we have enough doctors, and increased numbers of trainee doctors would be something I would absolutely support.
But we have plenty of clinical staff who aren't doctors who do great jobs and there's absolutely no need to suggest they are dangerous because the public don't have a full awareness of them. Loads of roles that exist now either didn't exist or have a wider scope than they did before.
That doesn't mean that there aren't risks, that they won't make errors (no one can be guaranteed not to make errors) or that they don't need to be regulated, monitored and with suitable planned roles.
But the NHS is in a state and we need more clinicians and to create a sustainable service. Physicians associates, alongside other clinicians and hopefully and expanded number of trainee doctors seem to me like a great and sensible way to do this.
