Background: Patient safety issues in pre-hospital care are poorly investigated. The aim of the planned study is to

survey patient safety problems in pre-hospital care in Sweden.

Methods/Design: The study is a retro-perspective structured medical record review based on the use of 11 screening

criteria. Two instruments for structured medical record review are used: a trigger tool instrument designed for

pre-hospital care and a newly development instrument designed to compare the pre-hospital assessment with

the final hospital assessment. Three different ambulance organisations are participating in the study. Every month,

one rater in each organisation randomly collects 30 medical records for review. With guidance from the review

instrument, he/she independently reviews the record. Every month, the review team meet for a discussion of

problematic reviews. The results will be analysed with descriptive statistics and logistic regression.

Discussion: The findings will make an important contribution to knowledge about patient safety issues in prehospital

care.
