The short answer
Use the three stages most independent providers follow: a local response, an internal review by someone not involved, then independent adjudication through ISCAS if your practice or hospital subscribes. Acknowledge in writing within three working days and send a full reply within 20 working days, which is the ISCAS stage 1 standard. Call your consultant's indemnifier early for anything clinical.

Questions
Frequently asked questions
Should I apologise if we did nothing wrong?
You can say you are sorry the patient had a poor experience without admitting fault. Where something did go wrong, say so plainly.
When must the consultant's indemnifier be told?
Before replying to anything about clinical care, treatment outcomes or a possible claim. Most indemnifiers prefer to hear early.
Do we have to use ISCAS?
Only if your practice or the hospital subscribes. If not, your final stage should name the independent route that applies.
The complaint is about the hospital, not us.
Pass it to the hospital's complaints lead with the patient's consent, tell the patient you have done so, and agree who replies.
Can we reply by email?
Yes, if that is how the patient contacted you. Keep it in the same structure as a letter and save a copy.
What if a complaint appears as an online review?
Reply briefly and politely, never confirm they are a patient or discuss their care, and invite them to contact you directly.
