BACKGROUND |
An opportunity was identified to compare perceptions of the occurrence and types of missed care at a comprehensive cancer center. |
PURPOSE |
The purpose was to evaluate the difference in perceived occurrence and types of missed care between medical, surgical, and hematologic oncology units in the context of a newly implemented patient care delivery system, Primary Team Nursing (PTN). |
METHODS |
A descriptive, repeated-measures design was used. The MISSCARE survey was distributed electronically to 580 staff members across 6 inpatient units. |
RESULTS |
Frequently perceived elements of missed nursing care were ambulation, turning every 2 hours, and care conference attendance. At the time of study implementation, surgical units reported 0.24 higher scores than medical units (P = .017); hematology units reported 0.26 lower scores than surgical units (P = .005). PTN stat... |
CONCLUSIONS |
Study findings suggest that perceived missed care in a comprehensive cancer center is similar to that in other hospital settings.Atypical Clival Chordoma in an Adolescent without Imaging Evidence of Bone Involvement. |
