Abstract
Background: Most reports of sickness absence come either from company records, which are limited to specific workforces, or rely on self-report. Electronic recording of sickness certification in primary care medical records provides an alternative source of information.
Purpose: To investigate the validity of electronic sickness certification records in primary care.
Methods: Analysis included 292 primary care LBP consulters, who returned a questionnaire including self-reported work absence, and consented to medical record review. Sickness certification records for 2001–2 were downloaded. Self-reported sickness absence for the previous 2-weeks was matched with electronic records for the same time period. Records were considered to match if there was no reported absence and no certificate, if there was reported absence > =7 days and a certificate, or if reported absence was < 7 days and no certificate was issued.
Results: Overall, 84% of records matched; 87% of employed consulters and 90% of unemployed consulters. Among the employed, 100% of reports of no absence did not have a certificate, 49% of reported absences > =7 days were matched by a certificate for the same time period and lastly, 80% of reported absences of < 7 days did not have a certificate.
Conclusion: We have demonstrated that people with none or short self-reported work absences do not have sickness certificates in their records, but only a small proportion of people with longer self-reported absences appear to have certificates. Further work will investigate possible reasons for non-matching, these may include non-requirement of a certificate, recall errors or incomplete recording of sickness certificates.
