There are many parties that can be found liable for medical malpractice
cases, depending on what caused your injury. To name a few:
The hospital itself - Whether there was a paperwork mix-up, negligence due to understaffing,
or one of the hospital's doctors acted in a manner that led to your injuries,
the hospital may be held responsible for damages
The pharmacy - If there is a prescription error or the pharmacist fails to warn you
of side-effects of the drug you are being prescribed and this results
in your injury, the pharmacy may be held responsible
Drug manufacturers - If the drug itself caused you harm, the manufacturer may be held liable
for producing a faulty or dangerous drug
