A healthcare system is evaluating a novel pharmacist-led medication reconciliation intervention to reduce 30-day hospital readmissions for patients with congestive heart failure. In a randomized controlled trial, the standard of care group had a 30-day readmission rate of 20%. The intervention group, which received the new pharmacist-led program, had a 30-day readmission rate of 15%.
Based on these trial results, what is the number needed to treat (NNT) to prevent exactly one additional hospital readmission?
Cevap: 20 patients
Cevap
20
The number needed to treat (NNT) is calculated as the inverse of the Absolute Risk Reduction (ARR). The ARR is the control event rate minus the experimental event rate (). Therefore, the NNT is patients. This metric helps hospital administrators evaluate value-based care programs by quantifying how many resources (in patient units) are required to achieve one positive clinical outcome.
