They can't refer patients to hospital consultants or social workers or anything useful like that.
They do have safeguarding responsibilities - so, say to a 12 year old girl came in, asking about contraception and they suspected, she was a victim of CSA? Likewise, pharmacies take part in the Ani campaign - whereby victims of domestic abuse can go in and ask for ANI, a code word for help? (Action needed immediately, iirc)
Then, they have to watch out for signs of addiction - so, they shouldn’t sell people codeine, if they are asking for it too often? Ditto other OTC, which can be abused.
Someone collapsed in a supermarket - the pharmacist went and gave CPR, although the customer died from a head injury.
They have to check prescriptions are legal - ie the correct name, address and dosage. What if a GP prescribed the adult dose of a drug to a baby? It’s the pharmacy, who are supposed to pick that up.
Some supply methadone and/or a clean needle exchange. Which is more cost efficient for the NHS - give out clean needles to addicts; or have to treat diseases like HIV, hepatitis, etc passed on by dirty needles?
These are just a few examples of what pharmacists do…..However, they are not GPs. It’s like asking the garage to fix your gas boiler, then complaining they haven’t done it right!
