Why Proving Your Treatment Is Effective Requires High Response Rates

Why Proving Your Treatment Is Effective Requires High Response Rates

So what?  20% is a lot of patients.  Why can’t I just assume that these patients are representative of all of our patients and extrapolate their results? 

Unfortunately, this isn’t accurate.  To see why, let’s look at the patients who responded to one year post-treatment research requests from three groups of treatment centers in the Vista Research Network:

Percentage of Respondents Who Were Abstinent at One Year Post-Treatment

Wow – in all three groups, between 81% and 85% of the patients said they were abstinent one year after leaving treatment.  So all of these groups could claim success rates of over 80%, right? 

In a word, NO. Claiming such ridiculously-inflated success rates has cost the addiction treatment industry dearly.  As much as families would love to believe that more than 80% of a rehab's patients are doing well a year later, they know b.s. when they hear it.  And once a rehab blatantly lies to them, its credibility is forever shattered.

In order to accurately measure success rates, you can only count as successful those patients who actually respond to your request and tell you that they’re meeting their drug and alcohol usage goals.  If a patient doesn’t respond, you have to assume they’re not doing well.  Let’s look at the patients from the three groups of Vista centers again, this time taking response rates into account:

One Year Abstinence Rates by Center Effectiveness

What a difference! Forty-four percent (44%) of the patients attending centers in group C were reachable and abstinent at one year post-treatment compared to 37% in Group B and 28% in Group A.  These three groups, which looked so similar when we considered only patients who responded, have dramatically different success rates!  In fact, this makes sense, because the patients are grouped by the success rates of the center they attended.  Those in Group C attended treatment centers with above-average success rates, those in Group B had average success rates and those in Group A were below average.

Response rates matter. A lot.  Our research has shown that the patients who don’t respond are statistically quite different (with a confidence level above 99.9%) from those who do.  Non-respondents are more likely to have left treatment against medical advice, to have had shorter lengths of stay, and to have been in treatment for heroin or cocaine, the hardest drugs to stop using:

Response Rates Matter

 If you want to show that your treatment center’s outcomes are better than average, you must use an outcomes research methodology that entices a high percentage of your patients to respond. Remember, if you only reach 20% of your patients, you’ll never be able to accurately claim a success rate of more than 20%.

Vista has built an outcomes research system that allows us to consistently reach a strong percentage of our client’s patients at one, six, and twelve months post-treatment.  If you’re ready to prove how effective your treatment is, please check out our demo and low pricing, or reach out to me directly for more information.
