Age Alliance Wales and the Bevan Foundation are carrying out research around the difficulties faced by older people in Wales, and their carers, when attempting to make an appointment with a GP. This could include dealing with a complex booking system, dealing with obstructive receptionists, making an appointment at a suitable time or facing physical problems in getting to the surgery (amongst other issues).
Age Alliance have an online survey where people can share their experiences, available at https://www.surveymonkey.co.uk/r/AccessGP
