PMID 40833508WHAT IT FOUND
A pressure-injury prevention bundle was associated with more days without a pressure injury and lower total costs than routine care.
But patients were not assigned by chance and bundle implementation cost was omitted, so treat the cost saving as tentative.
Key findings
01The bundle group had 298.8 mean days without a pressure injury, compared with 19.7 mean days without a pressure injury in the routine care group.
02Mean total cost was 36,029.88 SAR lower in the bundle group than in the routine care group, and the difference was statistically significant.
03The bundle group was reported as cost-effective because it had lower total costs and more days without a pressure injury than routine care.

What it does not show
Patients were not randomly assigned, so preexisting differences could explain the outcomes. Mean age was 64.8 years in the routine care group and 58.7 years in the bundle group. The bundle group had a longer mean length of stay (298.8 days) and lower mortality (22%) than the routine care group (140.6 days; 28%), so the groups may not have been comparable. The cost to implement the prevention bundle was not included in the analysis. Pressure injury severity and stage were not accounted for in the length-of-stay or cost comparisons. The study was conducted in one hospital in Saudi Arabia, so generalizability is uncertain. The bundle combined several interventions, so the contribution of any single component cannot be separated.
The easy way to misread this
Do not conclude that the bundle definitely caused fewer pressure injuries or saved money. Patients were not assigned by chance, the groups differed in length of stay and mortality, and the cost of implementing the bundle was not included.
