Question 1 · Hard
A ward introduces hourly rounding and bed alarms to reduce falls. After 3 months, falls have dropped from 4.8 to 2.0 per 1,000 patient-days, but patients complain of broken sleep and night-time sedative use has doubled. In the Plan-Do-Study-Act cycle, what is the best next step?
- AAdapt the change and test it in a new cycle
- BAbandon the change because sedation has risen
- CAdopt the change and spread it hospital-wide
- DStop measuring because the falls target is met

Answer: A · Adapt the change and test it in a new cycle
In the Act step, the team decides to adopt, adapt or abandon a change based on the Study results. Falls fell, so the change works, but a balancing measure worsened: more sedatives and poor sleep can themselves cause delirium and falls. The best step is to adapt the change, for example quieter rounding at night, and test it again in another PDSA cycle. Spreading it now would spread the harm as well.
- B: The main outcome improved, so abandoning the change wastes a real gain.
- C: Spreading a change with a worsening balancing measure spreads the harm.
- D: Measurement must continue to confirm the gain holds and the harm is fixed.
