I'm always banging on about the need to publish "negative" results - well, I'm pleased to see this paper has received some air time. The authors investigated whether teams that were a member of a collaborative improvement process ended up with changes in their local organisational culture. The answer is mostly a "no".
"There was no significant effect of collaborative membership on quality-oriented climate and mixed effects on service quality. Doctors' ratings improved significantly more in intervention clinics than in control clinics, staff helpfulness improved less, and timeliness of care declined more. Ratings of doctor-patient communication and willingness to recommend doctor were not significantly different between intervention and comparison clinics."
Improving organizational climate for quality and quality of care: does membership in a collaborative help?
