Table 1 Overview of study aims
Overall research question: What are the relevant components of capacity that determine PEWS sustainability in low-resource hospitals? | ||
|---|---|---|
Aim 1: Changes in capacity over time | Question | How does capacity for sustainability and its components change over time through the phases of PEWS adoption, implementation, and sustainability? |
Hypothesis | Capacity develops during early implementation and increases over time | |
Aim 2: Sustainment and patient outcomes | Questions | How do changes in overall capacity and its components predict (a) PEWS sustainment or abandonment and (b) improvement in patient outcomes? |
Hypothesis | Capacity and its components predict PEWS sustainment and continued reduction in clinical deterioration event mortality over time | |
Aim 3: Develop sustainability strategies | Questions | What are staff perceptions of challenges to capacity development and their impact on PEWS sustainability in low-resource hospitals? What are potential strategies that promote sustainability in these settings? |
