Based off the papers I read, we can go with validity of Patient Safety Indicators and their cost-effectiveness being our problem. Cost-effectiveness would be affected by the validity because if Patient Safety Indicators are not valid, cost-effectiveness decreases since there are still more potential adverse events that could be happening that are not being recorded by the patient safety indicators.
P: every client < we can narrow this if you want
I: Patient Safety Indicators
C: Using patient safety indicators and not using them/valid indicators vs more updated indicators
O: Patient safety outcomes and cost
T: within the next 5 years
I came up with this: Are patient safety indicators valid and cost-effective regarding improving patient safety outcomes?
Hopefully this combined PICOT question puts us in a more narrow direction. Feel free to change it.
