摘要:

AbstractAn historic perspective on the development of the National Cancer Institute's series of cancer atlases is provided. Emphasis is placed on the role which emergent questions concerning environmental determinants of cancer played in the acquisition and utilization of data resources. Studies which were fielded as a consequence of the atlases are highlighted. The legacy of the collective effort of many persons who worked on the development of the cancer atlases – the facilitation of many current epidemiologic investigations – is discus

摘要:

AbstractThis article identifies geographical contexts important in differentiating infant mortality in Alaska and uses spatial processing models to link and analyse multi‐source data. Information characterizing geographical locations are collected from Alaska's vital statistics for the years 1982–91 and the 1990 Census. Geographic information system (GIS) techniques are applied to identify spatially homogeneous regions, assess spatial compatibility across databases, and allocate geographical units across boundaries. A primary goal of this paper is to encourage spatial linkage and analysis techniques for vital statistics and census data. By demonstrating the interplay of tabular, graphical, and mapping techniques on Alaskan infant mortality, this analysis describes procedures for conducting epidemiological research with data spatially defined at distinct geographical lev

摘要:

AbstractProbabilistic linkage technology makes it feasible and efficient to link large public health databases in a statistically justifiable manner. The problem addressed by the methodology is that of matching two files of individual data under conditions of uncertainty. Each field is subject to error which is measured by the probability that the field agrees given a record pair matches (called themprobability) and probabilities of chance agreement of its value states (called theuprobability). Fellegi and Sunter pioneered record linkage theory. Advances in methodology include use of an EM algorithm for parameter estimation, optimization of matches by means of a linear sum assignment program, and more recently, a probability model that addresses bothmanduprobabilities for all value states of a field. This provides a means for obtaining greater precision from non‐uniformly distributed fields, without the theoretical complications arising from frequency‐based matching alone. The model includes an interative parameter estimation procedure that is more robust than pre‐match estimation techniques. The methodology was originally developed and tested by the author at the U.S. Census Bureau for census undercount estimation. The more recent advances and a new generalized software system were tested and validated by linking highway crashes to Emergency Medical Service (EMS) reports and to hospital admission records for the National Highway Traffic Safety Administration (N

摘要:

AbstractLinkage of same‐person records across multiple databases relies on high‐quality, uniformly available identifying information. These data quality issues become increasingly important when personal names are not available for record linkage. Using deterministic decision criteria, we linked records from two population‐based files in the absence of personal names. The sensitivity of anonymous record linkage procedures ranged from 32 to 85 per cent for the two years studied, and the positive predictive value (PPV) ranged from 14 to 99 per cent. Decreasing sensitivity and PPV were primarily attributed to (1) errors in computerized identifying information and (2) the deterministic decision criteria specified for record linkage. An evaluation of the contribution of personal names to the quality of record linkage found no measurable i

摘要:

AbstractEfforts to utilize Uniform Hospital Discharge Data Sets (UHDDS) for epidemiological studies have been hampered by the limitations of those databases. The purpose of this paper is to illustrate that linking to external databases can provide the verification necessary to overcome many of those limitations. This method has dramatically altered study design at the Connecticut Hospital Research and Education Foundation and has provided an efficient method for specifying data collection weaknesses within the resident databases.
