From “Changes in Nonprofit Hospitals’ Finances, Operations, and Quality of Care After Using Management Consultants,” published in JAMA:
Nonprofit hospitals in the US (n = 2343) collectively spent more than $7.8 billion on management consulting services from 2009 to 2023. A stacked difference-in-differences design comparing 306 US nonprofit hospitals that used a management consulting firm for the first time with 513 matched hospitals that did not use a management consulting firm during the study period found little evidence of substantial, statistically significant, or systematic changes attributable to management consulting engagements.
No surprise there. As the saying goes, “capable of anything and culpable for nothing.”
