Results: We assessed a random sample of 1066 electronic patient files. The use of standardised tools to
assess pain was registered in zero to 52% of the electronic patient files per organisation. Registration of
(non-)pharmacological pain treatment was found in less than half of the files. According to the files,
pharmacological pain treatment deviated from the guideline in 73–99% of the files. Time of
administration of medication was missing in 73–100%. Reassessment of pain following pain medication
was recorded in half of the files by the HEMS, but not in files of the other organisations.
