BACKGROUND The effects of inaccurate death certificates on cause of death statistics are uncertain. Since 2008, Akershus University Hospital has systematically corrected all death certificates. The effects of these corrections on the total cause of death statistics from the hospital were studied. MATERIAL AND METHOD ICD-10 codes for the underlying cause of death on the original and the correc...

OBJECTIVE Diabetes is the sixth leading cause of death in U.S adults, which may be an underestimate because of under-reporting on death certificates. In this study we examined death certificate sensitivity and specificity for diabetes, as well as the factors related to better reporting, in a community-based sample. RESEARCH DESIGN AND METHODS Death certificates were obtained for 3,209 deceden...

BACKGROUND Population-based mortality statistics are derived from the information recorded on death certificates. This information is used for many important purposes, such as the development of public health programs and the allocation of health care resources. Although most physicians are confronted with the task of completing death certificates, many do not receive adequate training in this ...

BACKGROUND: We aimed to determine optimal strategies for complete mortality ascertainment comparing death certificates and United States (US) Veterans Administration (VA) records. METHODS: We constructed a cohort of California veterans who died in fiscal year (FY) 2000 and used VA services the year before death. We determined decedent status using California death certificates linked to VA util...

A common way to protect objects in distributed systems is to issue authorization certificates to users, which they present to gain access. In some situations a way is needed to revoke existing certificates. Current methods, such as having a master revocation list, have been designed to work efficiently with identity certificates, and do not take into account the delegation of certificate-issuin...

The consequences of lacking birth certificates remain largely unexplored in the economic literature. We intend to fill this knowledge gap studying the effect of lacking birth certificates on immunization of children in the Dominican Republic. This is an interesting country because a significant number of children of Haitian descent face the consequences of lacking proper documentation. We use t...

Public key infrastructure (PKI) has emerged as a critical technology for identity management in e-commerce and e-government and over a hundred Certification Authorities across the globe offer certification services. Despite the passing of legislation in many countries to give equal legal weight to electronic signatures as to handwritten ones, the overall market for digital certificates has not ...

While the technologies for generation of electronic signatures are well-established in public-key infrastructures, the validation of electronic signatures still shows some open problems. The verification of the validity of an electronic signature requires high degrees of diligence, time and effort for the local configuration and management of trusted certificates and their revocation status. A ...

BACKGROUND The inaccuracy of death certification can lead to the misallocation of resources in health care programs and research. We evaluated the rate of errors in the completion of death certificates among medical residents from various specialties, before and after an educational intervention which was designed to improve the accuracy in the certification of the cause of death. METHODS A 9...

In this paper, we proposed a formal representation of certificate validation in Pretty Good Privacy (PGP) and X.509 systems. This representation uses new logical assertions to support public-key based certification systems and different trust levels. Although the meanings of some of those assertions are different in PGP and X.509 cases, the certificate validation can be expressed using the same...
