Intra-hospital transport: clinician information. In: JBI+Connect
Includes some useful references discussing factors associated with risk and safety.

PubMed
(“Patient Transfer”[MAJR]) AND shift AND (risk OR error* OR incident* OR safety)

Pezzolesi (2010) looks to be the most relevant. It discusses percentage of incidents that occurred during shift change.

CINAHL
(MH “Transfer, Intrahospital”) AND shift AND (risk OR incident* OR error* OR safety)

DId not see any studies specifically examining shift change and transport problems, but there are several articles discussing patient safety in the transport process. Those articles may reference other evidence.
