Treatment summary details needed

Hello all, I am Aayushee, I am currently living in cork to support my sister on her cancer journey. We are originally from India. I have a doubt, my sister was admitted in mercy university hospital cork for 26 days as she developed an infection in surgical site post surgery, we haven’t received any discharge/ treatment summary containing the details of her treatment during that duration. She is currently undergoing chemotherapy and we would need the same details when she is done with her treatment as this would be helpful in taking it back to India for second opinions from doctors. How can I get these?
We had reached out to FOI for scan reports and have received them, but I am still not clear about these treatment summary details.
