"Lack of care while in hospital"

My parent was taken to PACS to have their ulcerated wound redressed recently and it was suggested they go to the Emergency Department at Geraldton Regional Hospital by the staff from PACS as the wound smelled and was horrendous.

My parent's friend took them to PACS and these were their words. 

My parent's ankle & toes were swollen and the redness was travelling up to their knee. 

The stench from the foot was absolutely disgusting and their friend demanded my parent get sent to ED and the PACS staff agreed. 

My parent was admitted to hospital and both my parent and their friend was told that they would be in hospital for 5 days and an IV drip antibiotic. 

My parent gave their possessions, including keys and money to their friend to take home for them. My parent's friend went and picked them up 5 days of clothes and took them back to the hospital.   

The hospital rang me and asked could I be put down as next of kin and I said yes and gave them my details (name and phone number) and told them I had returned to Perth and would not be back in Geraldton for another week and a half, so could they please take my parent's friend's phone number as they were the only person in Geraldton that was there to care for my parent. The friend's number was taken by the hospital clerk. 

A doctor contacted me and said my parent had an infection and needed to stay in hospital, so I messaged them details of my parent's doctor's report as well as medical history and medications. 

Now this is where my complaint starts:

My parent was definitely not given the duty of care that they should have been given in the opinion of both myself and my parent's friend.

The information below was given to me by my parent's friend:

Day 1 - the hospital started the IV drip. My parent was told they could shower and get the wound wet. 

(PACS had told my parent they were not to get this wound wet)

The wound was not dressed (as far as I have been told).

Day 2 -my parent was told they could go home and the hospital would organize them to receive the IV drips at home twice a day. The wound had still not been dressed and was open to the air. The hospital did not ring me as their next of kin, nor did they ring my parent's friend to say my parent could go back home! 

My parent was told the hospital will ring them a taxi to get home. 

No one asked my parent if they had house keys or money to pay the taxi. 

Fortunately, my parent's friend went up to the hospital to see them and my parent told them this is what they had said (as I have been told). My parent's friend was fuming that my parent was being discharged, and we (the family) are all upset that no-one was contacted about the details of my parent's situation. 

The friend then took my parent home in their car and when they went to get out of the car, my parent's long pants rolled up as they were getting out the car, revealing that the wound had not yet been dressed and when they asked my parent if they had dressed it at the hospital, they said no not at all. 

I do not think we are overreacting, this has concerned our family a lot as my parent lives alone at home and we need to be notified if they are discharged from hospital and what is happening with their care.

I do expect a response to this!
