It sounds to me like the hospital is responsible and negligent in their procedure - they appear to be trying to cover it up - and hoped you wouldn't notice (and I'm not one of those people who's all up on suing people and companies - or someone who sees a conspiracy everywhere ) - but if a patient (healthy for the most part) dies unexpectedly - an autopsy should be performed - I do believe this may be the hospitals call unless the family chooses to push for it. Hospitals are in a unique position in that if a wrong drug is given and kills someone. it can be covered up. Not saying he received the wrong drug - just giving you an example. So if they're the ones giving the meds and they're the ones who are attributing the death to XYZ - then they have far too much power! They would choose not to investigate knowing that his death was untimely and likely their responsibility - I know your dr. Sounsd great and knowledgeable and super nice. But that doesnt mean he is not responsible. Even if a death is suspicious who's to say? The dr treating the patient? If he made a mistake - giving the drug late, not making sure the patient was being well monitored - not making sure a heart monitor was applied ( these would -should all be in the Drs. Orders in the chart - ) or even not reading the contraindications and warning correctly or thoroughly - and then he is the one called in to pronounce... Or even another dr. It's very easy to sign off and say... Natural causes... No dr. Wants to make troubl for another dr. Especially a collegue - and no dr. Wants to lose his licence - so given the choice... Like it or not - and nice or not he may choose self preservation...
I'm not sure if I'm thankful I wasn't offered Erbitux ( there was a clinical trial they were considering for me) but I'm grateful to you for the warning and trying help others. Take care. And do make the drug company aware.
