Associations of Patient and Staff Outcomes With Inpatient Unit Designs Incorporating Decentralized Caregiver Workstations: A Systematic Review of Empirical Evidence

Objectives:: This systematic literature review synthesizes and assesses quality of research addressing associations of patient and staff outcomes with inpatient unit designs incorporating decentralized caregiver workstations.

Background:: A current hospital design trend is to include decentralized caregiver workstations on inpatient units. A review of literature addressing decentralized unit design is needed.

Methods:: The systematic review methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Database searches were conducted for studies published in peer-reviewed journals through October 2017. Included were empirical studies associating patient and/or staff outcomes and unit design with decentralized caregiver workstations. Individual studies were evaluated for quality using established methods, and Grading of Recommendations Assessment, Development and Evaluation (GRADE) and GRADE-Confidence in the Evidence from Reviews of Qualitative Research (GRADE-CERQual) guided rigorous inspection of evidence quality and strength for quantitative outcomes and qualitative findings, respectively.

Results:: The search yielded 1,096 records with 36 full-text articles examined and 12 articles included in the final review. This work was dominated by studies with limited analyses. Staff outcomes have been most widely studied, especially collaboration/communication and walking. Overall, studies exploring decentralized nursing as a design intervention have produced limited results for both staff and patient outcomes. Strength of evidence of the current literature with quantitative methods as a whole was rated very low quality.

Conclusions:: Although varying degrees of caregiver workstation decentralization in inpatient units are now common, the literature addressing the impacts of such designs is of very low quality and shows inconsistency in associated outcomes. Rigorous, well-designed studies with consistently defined design and outcome measures are needed for greater confidence in determining any effects of decentralized unit design.
