Make better decisions

Our experts will remove ambiguity and misleading data, leaving you with clear options

"A" Grade

An "A" grade study is like a top-tier, well-built car. You can trust it to perform exceptionally well on the road, just as you can trust its findings to guide medical decisions.

"B" Grade"

A "B" grade study is akin to a decent, reliable car. It's not the absolute best, but it's still trustworthy enough to get you where you need to go. Similarly, its findings are still valuable for making medical decisions.

"U" Grade

However, a "U" grade study is like a broken-down, unreliable car that might not even start. Just as you wouldn't want to risk driving such a car, you can't rely on the findings of a "U" grade study to predict patient outcomes accurately.

Technical jargon and complex data

The information you need to make the best decisions is often hidden behind complex data and technical jargon. Even if you have the time to sift through it all, you may not have the expertise to interpret it accurately. That's where we come in. Our experts will remove ambiguity and misleading data, leaving you with clear options.

“Sifting through all the resources, filtering the pertinent information, deciphering what is meaningful, excluding bias and misleading data, is a time consuming process.”

At Health Decision Key we have experienced and passionate medical professionals who specialize in this task and always provide a clear and concise report detailing resources involved and the evidence needed to make decisions.


Cooking Analogy


If you want to cook something and you go to the Internet for a recipe. What would you do if you knew beforehand that 60 to 70% of the recipes were so poorly done that you couldn’t rely on the quality of the food.

Turns out that 60 to 70% of the articles published in the medical literature are of such poor quality that Physicians can’t rely on them to predict what will happen to their patients. What can doctors do to sort these issues out ? Turns out there is a way for doctors to decide which articles are useful and which aren’t. This is called critical appraisal.

Here’s how critical appraisal works. A medical study is a valuated for six criteria that determine whether the study is it well done enough to be usable. Here are the six criteria.

  1. patients must be randomly assigned to either the treatment or the placebo or no treatment group
  2. neither patients nor doctors must know which patient is getting a treatment or a placebo. This is known as blinding.
  3. the way patients are assigned to the two groups must not allow tampering or manipulation of any kind. This is known as concealment of allocation.
  4. patients must be evaluated in the same group, to which they were randomized
  5. both groups must have the same risk factors at the start of the study
  6. both groups must be treated equally except for the treatment in question

If one or more of these criteria are not followed, then the study is less likely to predict the results of the medication or treatment for a given patient. When we evaluate medical studies using the six criteria, we give them a letter grade
A – High quality, can be useful for decision making
B – Not as good as A, but still good enough
U – unusable not well done enough to be an accurate predictor of patient outcomes

When we report results, we will use these three grades. If it is an A or B, you can be reasonably confident that the treatment or medication will perform as advertised. If we give the study a U rating, it means that the study is so poorly done that we are not certain that the proposed treatment/medication will provide the advertised benefit. In that case, you will need to discuss this with your physician and decide if you are comfortable going forward. Remember just because the evidence is a poor quality doesn’t mean that the treatment or medication won’t produce the benefit; it just means you don’t know for sure.
