Best practice

When discussing medical treatments or interventions, use "decreased efficacy" to accurately describe situations where the treatment is not working as well as expected. For example, "The study showed a "decreased efficacy" of the drug in patients with advanced stages of the disease."

Common error

Be careful not to use "decreased efficacy" when you actually mean reduced efficiency. Efficacy refers to the ability to produce a desired result, while efficiency refers to the ability to do something without wasting resources. Use "decreased efficacy" when the treatment or method is simply not as effective as it used to be. For example, don't say 'The "decreased efficacy" of the process led to higher costs'; instead, say 'The decreased efficiency of the process led to higher costs'.
