Mangelfull overvåking av skadedødsfall i norsk landbasert arbeidsliv

SAMMENDRAG Bakgrunn: I en tidligere studie av Arbeidstilsynets registreringer av arbeidsskadedodsfall 2000-2003 identifiserte vi – med supplering fra SSB (Dodsarsaksregisteret) – i alt 214 dodsfall i landbasert arbeidsliv blant bosatte i Norge. Av disse var 171 (80%) registrert i Arbeidstilsynet. Komplettheten varierte med naering og skadetype slik at suppleringen endret risikobildet. I denne studien har vi brukt NAVs yrkesskadedata og forsikringsselskapenes yrkesskaderegister DAYSY for a undersoke om ytterligere arbeidsskadedodsfall kunne identifiseres. Metode: Yrkesskadesaker fra NAV og DAYSY med skadedato 2000-2003 og dod innen ett ar, ble gjennomgatt og sammenholdt pa individniva med opplysninger i Dodsarsaksregisteret. Resultater: 32 nye arbeidsskadedodsfall ble identifisert. Gjennomsnittsalderen var lavere enn for de opprinnelige 214 (37 vs 46 ar). Andelen dodsfall pa grunn av transportulykker med personbil (ICD-10 V40-V49) var hoyere (41 vs 10%). Av de tilsammen 246 identifiserte dodsfall hadde Arbeidstilsynet registrert 70%, NAV 64%, Dodsarsaksregisteret 57% og DAYSY 20%. Fortolkning: Tilleggsinformasjon fra NAV og DAYSY endret lite pa det opprinnelige risikobildet basert pa informasjon fra Arbeidstilsynet og Dodsarsaksregisteret. Okningen i totalantallet stemte med vart estimat basert pa to datakilder. Manglende registrering i NAV og DAYSY kan delvis skyldes at det ikke var fremmet krav fra etterlatte om yrkesskadeytelser.

ENGLISH SUMMARY Background: In a previous study of fatal occupational injuries 2000-2003 registered by the Norwegian Labour Inspection Authority (NLIA) and supplemented from Statistics Norway (the Cause of Death Registry, CDR), we identified a total of 214 deaths in land based industries among residents in Norway. From these, 171 (80%) had been registered by the NLIA. The completeness in the NLIA register varied according to industry and type of injury, so that supplementing from CDR altered the distribution of risk. In the present study we have supplemented with two other data sources – the National Insurance Administration (NIA) and Finance Norway (FN) for private insurance companies – in order to see if further deaths from occupational injuries could be identified. Method: Cases of occupational injuries from NIA and FN with date of injury 2000-2003 and death within one year, were scrutinized and compared individually with information in the CDR by means of their unique personal identification number. Results: 32 new cases of fatal occupational injuries were identified. The average age was lower than for the original 214 (37 vs 46 years). The proportion of deaths of car occupants in transport accidents (ICD-10 V40- V49) was higher (41 vs 10%). Due to the small number added, the overall risk distribution remained the same. Of the total 246 deaths identified, the NLIA had registered 70%, NIA 64%, CDR 57% and FN 20%. Interpretation: The additional information from NIA and FN did not markedly alter the risk distribution based on information from NIA and CDR. The increase in total number of registered deaths from four sources was in accordance with our estimated number based on two sources. Some of the incompleteness in registration by NIA and FN indicates that not all the bereaved that were entitled to occupational injury compensation, had made such request.
