A treatment website announces a high success rate. Before using it to compare services, ask what counted as success. Completing a programme, reporting reduced substance use and remaining engaged with follow-up care are different outcomes.
A useful percentage needs a defined group and a time period. Ask whether the figure includes everyone admitted, only people who completed treatment, or only those who answered a later survey. Those groups can produce very different-looking results.
Try the denominator question
Consider a fictional service that admits 100 people. Sixty complete the programme, and 45 of those report a particular improvement. Reporting 45 out of 60 answers a different question from reporting 45 out of 100. Neither number tells you what happened to people who could not be contacted.
Ask when the outcome was measured and who collected the information. A questionnaire at discharge is not the same as a follow-up months later. A small, self-selected group should not be presented as if it predicts every new patient’s experience.
Use the answer as part of a clinical conversation
The NIAAA’s explanation of relapse describes a return to drinking as a reason to review treatment, rather than treating it as proof that all progress has disappeared. A single promotional measure may miss changes in health, safety, functioning and ongoing engagement with care.
Request a written explanation of the service’s measures and, where available, the published evaluation behind them. Look for the dates, limitations and population studied. A provider that acknowledges uncertainty gives you something more useful to discuss than an unexplained promise.
Bring that information to a qualified clinician when considering care options. The question is whether the service offers appropriate, evidence-based support for your circumstances, not which website displays the largest percentage. No programme can responsibly turn a group result into a guaranteed personal outcome.
