Monitoring health in Los Angeles County.

The University of California at Los Angeles School of Public Health, in collaboration with the Los Angeles County Department of Health Services, compiled data and developed a standardized format that displayed a comparison of mortality and morbidity data between Los Angeles County, the State of California, and the United States in 1960, 1970, and 1980 for 16 health topic areas. Findings noted both favorable and unfavorable health trends, as well as substantial data collection problems. In 1980, compared with the United States, the Los Angeles County rates for tuberculosis, gonorrhea, syphilis, and hepatitis B were as much as 45 to 128 percent higher, the homicide rate was more than double, and, for the population aged 65 years and over, the cirrhosis of the liver rate was more than 56 percent higher. The myocardial infarction rate was 58 percent lower in the population aged 18 to 64. Problems of inadequate data for many health indicators, lack of comparability in data, and conflicting information from different data sources were noted. These limitations with the data underscore the need to standardize data collection procedures and to extend the parameters on which information is collected. The approach represents a tool that could be used by many health departments to monitor their activities and set future goals.
