Death certificate only proportions should be age adjusted in studies comparing cancer survival across populations and over time
2015
Abstract Background The proportion of cases notified by death certificate only (DCO) is a commonly used data quality indicator in studies comparing cancer survival across regions and over time. We aimed to assess dependence of DCO proportions on the age structure of cancer patients. Methods Using data from a national cancer survival study in Germany, we determined age specific and overall (crude) DCO proportions for 24 common forms of cancer. We then derived overall (crude) DCO proportions expected in case of shifts of the age distribution of the cancer populations by 5 and 10 years, respectively, assuming age specific DCO proportions to remain constant. Results Median DCO proportions acros…
Accuracy of death certificates for amyotrophic lateral sclerosis varies significantly from north to south of Italy: Implications for mortality studies
2004
<i>Objective:</i> To evaluate the accuracy of death certificates (DCs) for amyotrophic lateral sclerosis (ALS) in different parts of Italy. Studies based on DC diagnosis for ALS have shown a reduced mortality comparing northern with southern Italy. These data are in contrast with results from other surveys on the incidence of ALS performed in Italy and other countries. <i>Methods:</i> Archives of neurological clinics from northern (Milano, Monza, Pavia, and Bologna) and southern Italy including islands (Napoli, Sassari, Palermo, and Messina) were searched for patients discharged with a diagnosis of ALS in the period 1970–1995. Subjects affected by definite/probable A…
Deaths Associated with Ankylosing Spondylitis in France from 1969 to 2009.
2017
Objective.To describe deaths for which ankylosing spondylitis (AS) was on death certificates in France.Methods.Death certificates in which AS was indicated were evaluated. Standard mortality ratio (SMR) was assessed.Results.AS appeared in 2940 death certificates. The mortality rate of AS seemed stable. The most frequent initial causes were diseases of the circulatory system [28.3% in the International Classification of Diseases, 10th ed (ICD-10)]. SMR adjusted for age and sex were 2.1 (95% CI 1.45–2.91) for infections and 0.43 (0.36–0.5) for cancers (ICD-10 period).Conclusion.This study found an increase in mortality from infectious and external causes of death; conversely, patients with AS…
Completeness and timeliness: Cancer registries could/should improve their performance.
2015
Abstract Cancer registries must provide complete and reliable incidence information with the shortest possible delay for use in studies such as comparability, clustering, cancer in the elderly and adequacy of cancer surveillance. Methods of varying complexity are available to registries for monitoring completeness and timeliness. We wished to know which methods are currently in use among cancer registries, and to compare the results of our findings to those of a survey carried out in 2006. Methods In the framework of the EUROCOURSE project, and to prepare cancer registries for participation in the ERA-net scheme, we launched a survey on the methods used to assess completeness, and also on t…
Accuracy of death certificates for motor neuron disease and multiple sclerosis in the province of Palermo in southern Italy
2002
Mortality studies based on death certificates (DCs) are relatively inexpensive and easy to conduct. Therefore, they are frequently used to evaluate variations of geographical and temporal patterns, particularly in uncommon diseases. Recent surveys of motor neuron disease (MND) and multiple sclerosis (MS) based on official mortality statistics in Italy showed a decreasing trend of mortality from northern to southern Italy. To evaluate if DCs are homogeneously recorded in Italy and whether or not they can be considered a good instrument for mortality studies, we assessed the accuracy of DCs for MND and MS in the province of Palermo, Italy, and compared our results with those reported in other…
Effects of record linkage errors on registry-based follow-up studies
1997
The importance of reliable record linkage for high quality-population-based disease registration is widely recognized. Systematic methodologic work is lacking, however, on the effects of record linkage errors on the use of disease registries for epidemiologic purposes. The present paper provides algebraic models describing the effects of record linkage errors on monitoring survival of registered patients, which is commonly performed by matching registry records against a database of death certificates, and on registry-based incidence follow-up of external cohorts. Homonym errors, that is, erroneous linkage of records that pertain to distinct individuals, lead to underestimation of survival …
