Flat Line

I realized I had not even a single "Z" poem, to round out an alphabetical collection I'm putting together. Here it is:

Zanzibar

Zanzibar;
I never wrote about that,
Could have been a great code word
As the vital signs went flat,
When Betty Sue checked out
Without any warning,
The family looked shell-shocked
In unexpected mourning.

It was a memorable transfer
From a hospital nearby,
Famous for screw-ups
Sending sick folks to die,
To save their reputation
Although, how could it be worse?
A death sentence hospital
The place had a curse.

Betty Sue landed
In cardiogenic shock,
There weren't many hours
Left on her clock,
And sadly, she didn't make it
To the end of our shift,
Zanzibar showed up
If you catch my drift.

Upon arrival we noticed
IV's, two weeks old,
Central-line insertion sites
Growing with mold,
It was truly disgusting
The level of substandard care,
She barely lasted six hours
It was a Zanzibar affair.

Zanzibar
Has acquired a definition,
Unexpected flat-line
Completing the mission.
