Objective:

This research aimed to evaluate the quantitative effects of new hospital design on adult inpatient outcomes.

Background:

Tenets of evidence-based healthcare design, notably single-patient acuity-adaptable and same-handed rooms, decentralized nursing stations, onstage offstage layout, and access to nature were expected to promote patient healing and increase patient satisfaction, while decreasing adverse events.

Methods:

Patient healing was operationalized through length of stay (LOS) and patient safety through three adverse events: falls, hospital-acquired infections (HAI), and medication-related events. Standard patient surveys captured patient satisfaction. Patient records from 2013 through 2017 allowed for equivalent time periods surrounding the move to the new hospital in August 2015. Stratified by hospital division where significant, pre/post comparisons utilized proportional hazards or logistic regression models as appropriate; interrupted time series analyses afforded longitudinal interpretations.

Results:

Observed higher postmove LOS was due to previously increasing trends, not increases after the move. In surgical and trauma units, a constant increase in falls was unaffected by the move. Medication events decreased consistently over time; medication events with harm dropped significantly after the move. No change in HAI was found. Significant improvement on most relevant patient satisfaction items occurred after the move. Call button response decreased immediately after the move but subsequently improved.

Conclusion:

Results did not clearly indicate a net change in adult inpatient outcomes of healing and safety due to the hospital design. There was evidence that the new hospital improved patient satisfaction outcomes related to the environment, including comfort, noise, temperature, and aesthetics.
