I agree with Ross.
Most people follow whatever their doctors say.
Some object to ANYTHING their doctors say.
And then there are some who do a lot of research and think about things. Sometimes they find their doctors are correct; somethings it's the reverse.
My husband is one case where our doctor's office -- NOT our doctor, since he is off on Wednesday afternoons, when John was going in for INR tests -- just couldn't increase John's dosage enough to get his INR in range after his MV repair. I started charting his INRs and dosage changes and saw we weren't getting there. So I called the office to speak to our PCP, who was on vacation, but I explained the situation to an office employee who knew I did my own testing.
I said the dosage increase was too low, and offered what I thought it should be.
I was told to have John go with my suggestion and our PCP would be notified.
John took a copy of Al Lodwick's algorithm dosing chart with him to his next INR test, and the MD on call sent back a copy of the dosing chart they were using.
Al's chart is much easier to follow than the chart the MD in our doctor's practice was using -- and it was getting John in range.
It used far too conservative of dosing increases to get him in range. His range was 2.0-3.0, and he was needing around 7mg to get there. My range is 2.5-3.5 and I was taking about 5-6mg. John is 4.5 years older than me; go figure.
Part of the reason that a lot of medical professionals "mismanage" warfarin patients is because they're just not interested in it. It's not something they do 100% of the time. And for many people, it's not an interesting subject. And they probably don't have a lot of in-depth training in it or have attended CE seminars on it.
My new cardiologist & I have discussed this. He's impressed with my knowledge & ability to manage my INR testing and warfarin dosages. His practice -- one of the largest in Fort Worth TX -- has a Coumadin clinic listed at
www.acforum.org. So I would assume (but remember what ASSUME means) that someone there is smarter than the average bear at managing warfarin patients.
