Hi,
I have experience with this, also having to complete the restoration form. You will definitely nurse again don't worry! It just takes a bit of time to get the relevant CPD etc together. For me I had to show evidence of verifiable CPD only, non-verifiable seems to be irrelevant now. I found Isopharm and DNN were fantastic for this. Keeping a log of your personal development plan is compulsory now too (not required for registration but just going forward). CPD topics that were covered were; Medical Emergencies, Health and Safety, Safeguarding, Radiation Protection, Clinical Governance, Oral Cancer, Legal and Ethical and Complaint Handling. Some of them may only be advisories but I did them all just to be sure! They need this information to ensure nurses are competent enough to return to the register, They gave me a figure, total hours that I needed to complete worth of CPD I had to submit a CPD log (theres a template of the GDC website) along with a copy of the course certificates for it to be valid. You also have to write a written reflection after each course, however this is usually prompted by the course provider and submit this too!
I would find out how much CPD you are required to do and start working your way through them, then at least your clear! I hope I have helped a little lovely and let me know how you get on!
Thanks Victoria
