Friends don’t take Friends to the Hospital

Never self-transport friend or family to the hospital if you suspect Heart Attack or Stroke.  Never.


Paramedics know which Hospitals specialize in treating specific medical conditions and symptoms. 
In Ontario, and most other places, Paramedics are highly trained and well equipped to assess the presence and severity of heart attack and stroke. Based on the patient presentation during their initial assessment the Paramedics will decide which hospital is the appropriate facility to treat the specific symptoms they are observing.  At the start of every shift and updated throughout each shift as changes occur, Paramedics are informed which hospitals in the region are receiving patients with specific symptoms.  A wide range of factors from off load delays, too broken equipment, to Doctors being away on vacation can effect which hospitals are receiving which patients. It would be impractical, perhaps impossible to keep the public updated on this information. The message to the public has to be when symptoms are observed Call 911 and let the Paramedics decide which hospital is best for your situation.

For two of the most common and most devastating medical emergencies, Stroke and Heart Attack, the most significant factor in determining patient outcome is time, specifically the time from the onset of symptoms to the time when blood flow to the affected part of the body is restored. When human tissue is denied blood due to a blockage in an artery it is denied oxygen and without oxygen tissue begins dying. In the case of heart muscle after 90 minutes some tissue will be dead and there will be permanent damage to the heart and loss of some heart function. In the case of Stroke, brain cells may last 150 minutes in a low oxygen environment but beyond that damage is typically permanent and full restoration of all function is unlikely.

In Ontario 15 of 165 hospitals have fully equipped and staffed Cardiac Catheterization Labs that operate around the clock every day.  At these facilities Cardiac Intervention Teams perform the procedure that is most effective for restoring blood flow to affected heart muscle, emergency angioplasty or PPCI – Primary Percutaneous Coronary Intervention.  Nearly 12 million of Ontario’s 13 million residents live close enough to one of these hospitals to make the 90 minute window if 911 is called as soon as definitive symptoms are recognized.  If you self-transport a family member to the wrong hospital by the time you get inside and the staff identifies the problem and calls for an ambulance to transport the patient to the appropriate facility it is almost assured that the 90 minute window will be closed.

For Stroke the target is a moving one and the local hospital that is receiving Stroke patients may change throughout the day as the availability of a CT Scan machine and trained technicians is considered. Clot busting TPA Therapy – tissue plasminogen activator – can only be started after a CT Scan to confirm if the stroke is in fact being caused by a blocked (not ruptured) artery.  Again, getting to the right hospital, with the right equipment in the right timeframe is the only way to achieve the best possible outcome for Stroke.

What does the best possible outcome for Heart Attack or Stroke look like? What does it mean for patients, families and taxpayers when the best possible outcome is achieved? Stay tuned for the next blog in this three part series.
