Estimation of the Combined Effects of Ageing and Seasonality on Mortality Risk: An Application to Spain
2021
Abstract Despite the overwhelming evidence that shows the persistence of intra-annual variations on demographic events (deaths, birth dates and migration flows), life tables are computed and provided on an annual basis. This paper develops a new estimator for estimating sub-annual death rates that, considering the exact moment of occurrence (exact age and day) of events, concurrently accounts for ageing and calendar fluctuations. This paper also shows how modelling the intra-annual variations of death rates, through specific seasonal–ageing indexes, can be used as a tool for constructing new sub-annual tables from annual tables. This new methodology is exemplified using a real database of S…
Hospital readmission rates: signal of failure or success?
2013
AbstractHospital readmission rates are increasingly used as signals of hospital performance and a basis for hospital reimbursement. However, their interpretation may be complicated by differential patient survival rates. If patient characteristics are not perfectly observable and hospitals differ in their mortality rates, then hospitals with low mortality rates are likely to have a larger share of un-observably sicker patients at risk of a readmission. Their performance on readmissions will then be underestimated. We examine hospitals’ performance relaxing the assumption of independence between mortality and readmissions implicitly adopted in many empirical applications. We use data from th…
Time Trends in Hospital-Referred Stroke and Transient Ischemic Attack: Results of a 7-Year Nationwide Survey in France
2010
<i>Background:</i> Nationwide evaluations of the burden of stroke are scarce. We aimed to evaluate trends in stroke and transient ischemic attack (TIA) hospitalization, in-hospital case fatality rates (CFRs) and mortality rates in France during 2000–2006. <i>Methods:</i> Hospitalizations for stroke and TIA were determined from National Hospital Discharge Diagnosis Records that used the International Classification of Disease, 10th revision, codes I60, I61, I63, I64, G45, G46. CFRs and mortality rates were estimated from the national death certificates database. <i>Results:</i> The total number of stays for stroke increased between 2000 and 2006 (88,371 vs…
