The Finnish Hospital Discharge Register has satisfactory to very good completeness and accuracy for primary data, making it valuable for research despite limitations in secondary data recording.
Supports use of Finnish Hospital Discharge Register primary data in research; confirms satisfactory-to-high validity while cautioning on subsidiary diagnoses.
Completeness and accuracy in the register seem to vary from satisfactory to very good in the register as long as the recognised limitations are taking into account. Poor recording of subsidiary diagnoses and secondary operations and other rarely used items are the most obvious limitations in validity, but do not compromise the value of data in FHDR in being used in studies that are not feasible to conduct otherwise.
