Comparing causes of death of Hodgkin lymphoma and breast cancer patients between medical records and cause-of-death statistics.

OBJECTIVE: Obtaining accurate data about causes of death may be difficult in patients with a complicated disease history, including cancer survivors. This study compared causes of death derived from medical records (CODMR) with causes of death derived from death certificates (CODDC) as processed by Statistics Netherlands of patients primarily treated for Hodgkin lymphoma (HL) or breast cancer (BC). METHODS: Two hospital-based cohorts comprising 1,215 HL patients who died in the period 1980-2013 and 714 BC patients who died in the period 2000-2013 were linked with cause-of-death statistics files. The level of agreement was assessed for common underlying causes of death using Cohen's kappa, and original death certificates were reviewed when CODDC and CODMR showed discrepancies. We examined the influence of using CODDC or CODMR on standardized mortality ratio (SMR) estimates. RESULTS: Agreement for the most common causes of death, including selected malignant neoplasms and circulatory and respiratory diseases, was 81% for HL patients and 97% for BC patients. HL was more often reported as CODDC (CODDC=33.1% vs. CODMR=23.2%), whereas circulatory disease (CODDC=15.6% vs. CODMR=20.9%) or other diseases potentially related to HL treatment were more often reported as CODMR. Compared to SMRs based on CODDC, SMRs based on CODMR complemented with CODDC were lower for HL and higher for circulatory disease. CONCLUSION: Overall, we observed high levels of agreement between CODMR and CODDC for common causes of death in HL and BC patients. Observed discrepancies between CODMR and CODDC frequently occurred in the presence of late effects of treatment for HL.

Assessment of abuse-related injuries: a comparative study of forensic physicians, emergency room physicians, emergency room nurses and medical students.

A comparative study was made investigating whether emergency room physicians, emergency room nurses, forensic physicians, and interns are competent in describing, recognising and determining the possible cause of injuries. The injury assessment scores varied from good--adequate--fail and remained blank in various participant groups. Forensic physicians scored significantly better than emergency room staff and interns in the assessment of abuse-related injuries. There were almost no differences noted between emergency room physicians and emergency room nurses. For the functional group with more or less than 4 to 6 years of experience, no significant differences were noted for scoring good in all 5 cases. The fact that forensic physicians scored better than the emergency room staff is probably explained by the fact that almost all practicing forensic physicians have been officially qualified. Training in this field for all professionals involved in such assessment should be mandatory.
