Injury surveillance. A review of data sources used by the Division of Safety Research.

Injury surveillance by the Division of Safety Research in the National Institute for Occupational Safety and Health has the following two major purposes: the detection of significant changes in the status of worker safety to help define areas for research and the assessment of importance of various safety problems for priority setting in the Division. Surveillance of occupational injuries in recent years has realized a quantum improvement due to the availability of several extensive work-injury case data bases. The Division of Safety Research utilizes three of these to provide essentially independent sources of evidence for the identification and definition of problems for safety research. The National Electronic Injury Surveillance System, based on daily reports from a representative sample of hospital emergency rooms across the nation, provides case data such as age and sex of the injured worker, injury diagnosis, and product involvement. The Supplementary Data System annually provides worker's compensation case files which include the occupation and industry of the injured worker from selected states. A third level of detail is provided by the work injury report surveys of injured workers, conducted annually, and focused on specific accident types of injury groups. Findings, include high-risk occupations, age groups, tools, and equipment.

Alternative data sources and discrepant results in case-control studies of estrogens and endometrial cancer.

In most case-control studies, little attention has been given to two features that can affect the odds ratio: 1) self-selection of the people who are available for interviews, and 2) disagreements between the data obtained by medical records and by direct conversation. The authors investigated these problems during two separate case-control studies of estrogens and endometrial cancer. When interviews were attempted with all patients, fewer controls than cases were available. In samples of patients from a tumor registry, more controls than cases had died before the interview could be solicited, and fewer control patients could be located. In patients sampled from a diagnostic test registry, more controls than cases refused participation. The interview data about estrogen usage disagreed with previously recorded medical information in 16% (52/324) of patients). Among persons marked as "non-users" in medical record data, more cases than controls were available for interview and thus for redesignation as estrogen users. The bias produces a possible artificial increase in the odds ratio when interview and medical record data are combined. Since patients available for interview were systematically biased in favor of having both estrogen use and endometrial cancer, the odds ratio for this association should be calculated separately for record and for interview data.

Archaeological techniques for exhumations: a unique data source for crime scene investigations.

If exhumations to retrieve a body or body samples are conducted according to archaeological methodology, they may provide evidence on events which occurred during the interment process. This article discusses the exhumation methodology employed during exhumations in a tropical environment and provides a case study to serve as an example of the data that can be obtained beyond the simple recovery of human remains.

Methodological issues in a multicentric study of gastric cancer and diet in Italy: study design, data sources and quality controls.

The authors examine the problems of planning and conducting a multicentric case-control study on diet and gastric cancer in Italy. The solutions chosen for the study design, cases and controls identification, dietary interview, production of a common protocol for the field work are discussed. Results on the evaluation of the quality and comparability of collected data are presented. Further, compliance of cases and controls to the interview and to the blood and urine sampling with reasons of non-response are shown. Finally, the phases of the study and the methods for improving and controlling homogeneity among Centers are summarized.

Trends of HIV infections using the anonymous mandatory reporting system and other data sources in Switzerland and in the Federal Republic of Germany.

In Switzerland and in the Federal Republic of Germany the reporting of HIV infections is based on an anonymous mandatory reporting system for laboratories. In Switzerland, physicians have to complete a questionnaire on the patient's clinical status and risk behaviour. To make a rough estimate of the prevalence of HIV infections in the general population at low risk, data on blood donations are used in both countries. In Switzerland, additional data with information on positive and negative test results have been obtained since 1985 from anonymous test sites. In both countries, the data do not show evidence of an increasing incidence of HIV infection. The number of positive test results reported by the laboratories and physicians remains stable, and the rates of HIV-positive blood donations are declining. In the Federal Republic of Germany, homo-/bisexual men play the most important role in the epidemic, whilst in Switzerland, injecting drug users contribute most to the burden of HIV infection, and the proportion of persons probably heterosexually infected is increasing steadily. Possible selection biases need to be further discussed.

Data sources for estimating environment-related diseases.

Relating current morbidity and mortality to environmental and occupational factors requires information on parameters of environmental exposure for practitioners of medicine and other health scientists. A fundamental source of that information is the exposure history recorded in hospitals, clinics, and other points of entry to the health care system. The qualitative and quantitative aspects of this issue are reviewed.

Hospital records as a data source for occupational disease surveillance: a feasibility study.

To assess the feasibility of using hospital records for occupational disease surveillance and to evaluate the quality of the industry/occupation (I/O) information available in these records, the computer file of all discharge diagnoses from a large health maintenance organization during 1985 was reviewed. The frequencies of discharge diagnoses previously listed as Sentinel Health Events (Occupational), or SHE (O), were calculated and three possible SHE(O) diagnoses--lung cancer, bladder cancer, and toxic hepatitis--were selected for further review. Outpatient charts of patients discharged for each diagnosis were abstracted with regard to I/O information and the discharged patients were interviewed by telephone to obtain a lifetime occupational history. The accuracy of the I/O information obtained from the hospital chart was compared to that obtained by patient interview by number of digits matched on standard classification codes. The frequencies of matches for occupation and industry were greater for "usual" than for "last" categories with both cancer diagnoses, but were similar for "usual" and "last" categories with toxic hepatitis. To assess the proportion of each possible SHE(O) diagnosis that was related to workplace exposures, the I/O information obtained by interview was rated in a blinded fashion by an experienced occupational medicine physician. The highest probability ratings for work-relatedness were noted for lung cancer, primarily due to asbestos exposure. The results of this study suggest that hospital records can be used to identify possible SHE(O); if adequate I/O information is available, then work-relatedness can be assessed. However, the accuracy of I/O obtained from hospital charts is relatively low. The efficient and accurate collection of I/O information from hospital records will require the use of a simple, easily coded instrument to be routinely administered on admission.
