What's it like as an out-of-hours GP?
The scale of the "crisis" facing GP out-of-hours services has been revealed by BBC Wales research.
It shows Welsh health boards could not fill hundreds of shifts, equating to thousands of hours of GP-cover during the course of last winter. Patients consequently faced delays in seeing a GP at weekends or at night.
The Welsh Government said it was working with health boards "to improve out-of-hours services further".
Dr Mohan De Silva is a GP in Llandovery but also works at out-of-hours centres. He said cases can be quite acute and complex, with patients unfamiliar and some doctors - especially with unfilled shifts around them - can feel isolated.
Dr De Silva said a return to more career out-of-hours doctors needs to be considered.
