Could like point out the studies you mentioned?

The studies concerning long-term impact of surgical checklists I found all claim an improvement.

> Sustained use of the checklist was observed with continued improvements in process measures and reductions in 30-day surgical complications almost 2 years after a structured implementation effort that demonstrated marked, short-term reductions in harm. The sustained effect occurred despite the absence of continued oversight by the research team, indicating the important role that local leadership and local champions play in the success of quality improvement initiatives, especially in resource-limited settings.

The way they run these studies is crazy to me:

>Only 3 of 22 operating stations (13.6%) had a functioning pulse oximeter prior to the intervention; accordingly, a pulse oximeter (model 7500; Nonin Medical Inc) was installed at each operating station as part of the implementation effort

The addition of essential medical equipment surely won't bias our results!

One could argue the essential medical equipment was missing due to lack of checklists ensuring its existence. That said, yeah, it would have been better to do 2 separate studies then: one on adding the equipment and then one on checklists.
