Abstract

OBJECTIVES: Occupational exposures significantly contribute to the risk of adverse cancer outcomes, and firefighters face many carcinogenic exposures. Occupational research using cancer registry data, however, is limited by missing and inaccurate occupation-related fields. The objective of this study is to determine the frequency and predictors of missing and inaccurate occupation data for a cohort of career firefighters in a state cancer registry. METHODS: We conducted a linkage between data from the Florida Cancer Data System (1981-2014) and the Florida State Fire Marshal's Office (1972-2012). The percentage and the odds of having a firefighting-related occupation code in the cancer record were calculated, adjusting for other occupation and cancer-related factors. RESULTS: Among 3,928 career firefighters, nearly half (47%) were missing a registry-dervived occupation code and only 17% had a firefighting-related code. Males were more likely to have a firefighting-related code (OR = 2.31;95%CI: 1.41-3.76), as were those with more recent diagnoses (OR1992-2002 = 2.98;95%CI: 1.57-5.67; OR2003-2014 = 11.40;95%CI: 6.17-21.03), and those of younger ages (OR45-64y = 1.26;95%CI: 1.03-1.54; OR20-44y = 2.26;95%CI: 1.73-2.95). CONCLUSIONS: Accurate occupation data is key for identifying increased risk of advserse cancer outcomes. Cancer registry occupation fields, however, are overwhelmingly missing for firefighters and are missing disproportionally by sociodemographic and diagnosis characteristics. This study highlights the lack of accurate occupation data available for hypothesis-driven cancer research. Cancer registry linkage with external occupational data sources represents an essential resource for conducting studies among at-risk populations such as firefighters.

  • Four studies found that occupational data were not missing at random and that male patients were more likely to have occupational information in their record.

    The Discussion (page not specified) says occupation fields are missing disproportionately by case characteristics, including gender. The Results (page not specified) find that male Florida firefighters were more likely to have a firefighting-related occupation code, but do not establish that male patients generally were more likely to have any occupational information in their records. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The NIOSH Industry and Occupation Computerized Coding System, a free web-based system, was evaluated and recommended by several studies for increasing the quality of occupation data prior to analysis.

    “For researchers seeking to increase the quality of occupation data prior to analysis, the National Institute of Occupational Safety and Health (NIOSH) has created a free, web-based system called NIOSH Industry and Occupation Computerized Coding System78 that was evaluated and recommended by several studies.10,60,62,76”

    From The quality of social determinants data in the electronic health record: a systematic review (2021) · cites this paper as [60]

    The Discussion (page unavailable) describes NIOCCS as a web-based tool and reports that an eight-state study found it useful for improving occupation fields. It also calls such tools valuable, but this paper did not itself evaluate NIOCCS, and it cautions that the tool cannot remedy missing occupation information. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Six of the 7 studies (86%) that looked at the quality of occupational data primarily examined completeness, all noting that occupational information is frequently missing from the health record.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
