Rapid Response:

Hawthorne Effect

Perhaps this study should be re-titled "Effect of Academia taking an
interest in General Practice, with regular pep-talks", and subtitled
"Subliminal messaging re: managing Hospital Admission Rates" ?

It is interesting that this effect did not depend on the putative
interventions; there was no measurable difference in effect on
cholesterol or BP process measures, yet hospital admissions declined.
That's benefit enough, you might think.. until you ask " What happened to
patient well-being, morbidity and mortality ? "

Perhaps people who needed hospital admission didn't get it ??

One could focus further study on CHD morbidity. Such advice and keen
interest as was shown in this study , also pertains under the QOF
incentive scheme. Yet Des Spence is unimpressed with any outcomes
change.. Perhaps this is a new "Toyota Way" ? Give me academic
"personalised interest" anytime ( and some away-days !), instead of
blanket overburden with muda, mura, and muri ?
