Changes in malnutrition-related outcomes between preintervention (1 January 2015 to 31 December 2015) and postintervention (1 September 2016 to 31 August 2017) groups*
| Outcome | Preintervention | Postintervention | Change (p value) | Percentage of change |
| No of patients (ages 18+ years) malnourished or at risk of malnutrition | 985 | 1046 | ||
| Infection rates among patients malnourished or at risk of malnutrition | 14% | 9% | −5 (p<0.01) | −35.7 |
| Median LOS for patients malnourished or at risk of malnutrition | 8 days | 6 days | −2 days (p<0.01) | −25.0 |
| Median LOS for patients malnourished or at risk of malnutrition with an infection | 9 days | 7 days | −2 days (p=0.10) | −22.2 |
| 30–60 days of readmission rates among patients malnourished or at risk of malnutrition | 27% | 28% | +1 (p=0.58) | 3.7 |
*The data reflect the preintervention time period of 2015, and another 12 months of data in late 2016–mid 2017 (following the intervention period) to demonstrate the impacts of this QI project.
LOS, length of stay; QI, quality improvement.
