Why are a quarter of all cancer deaths in south-east England registered by death certificate only ? Factors related to death certificate only registrations in the Thames Cancer Registry between 1987 and 1989.
This paper describes the results of a study set up to investigate factors associated with the high proportions of'death certificate only registrations (DCOs) for all cancers registered in south-east England between 1987 and 1989 and to identify those which might be subject to registry intervention.
DCOs as a proportion of all registrations (n=162 131) were anlaysed by age, sex, district of residence, place of death and survival.
DCO registration ratios (standardised for age and sex) were then derived for each of the 56 districts in the Thames Regions.
A multiple logistic regression model was generated to estimate the effect of age at diagnosis, tumour survival and patient sex on final source of registration.
To minimise the number of dummy variables needed, each of the 56 districts was ranked into quartiles : quartile 1 contained the 14 districts with the lowest age-and sex-standardised ratios for DCO registrations and quartile 4 comprised the 14 districts with the highest DCO ratios.
Final source of registration was treated as a binomial trial (case notes or death certificates).
The significance of associations was measured using the deviance difference as an approximate chi-square statistic.
The effect of each variable on source of registration was estimated as an odds ratio.
Interaction terms were also fitted.
