Existing data sources do not provide comprehensive and timely information to adequately monitor drug-related mortality in Los Angeles County. To fill this gap, a surveillance system using coroner data was developed to examine patterns in drugrelated deaths. The coroner provided data on all injury deaths in Los Angeles County. A list of keywords that indicate a death was caused by drug use was developed. The cause of death variables in the coroner data were searched for mentions of one of the keywords; if a keyword was detected, that death was classified as drug related. The effectiveness of the keyword list in classifying drug-related deaths was evaluated by matching records in the coroner death data to records in the state death files. Then, the drug-related deaths identified using the keywords were compared to drug-related deaths in the state mortality files identified using International Classification of Death codes. Toxicological test results were used to categorize drug-related deaths based on the type and legality of the drug(s) ingested. Mortality rates were calculated for each category of drug and legal status and for different demographic groups. Compared to the gold standard state mortality files, the coroner data had a sensitivity of 95.6% for identifying drug-related deaths. Over three quarters of all drug-related deaths tested positive for opiates and/or stimulants. Males, Whites, and 35-54-year-olds each accounted for more than half of all drug-related deaths. The surveillance of drug-related deaths using coroner data has several advantages: data are available in a timely fashion, the data include information about the specific substances each victim ingested, and the data can be broken down to compare mortality among specific subpopulations.

Intimate partner violence (IPV) remains a pressing public health issue. Nationally, 1 in 5 women and 1 in 10 men have sustained severe physical violence from an intimate partner. Intimate partner homicides (IPH) are the most serious IPV outcome. This study examined documented IPH in Los Angeles County during 2017, analyzing if precipitating circumstances, victim demographics, victim/suspect relationship, and weapon type were related to how often a homicide was reported in online media stories. Cases were identified from the National Violent Death Reporting System (NVDRS), and standardized internet searches identified media articles associated with each case. Victim demographics from NVDRS and media articles were compared using Chi Square tests. Media report frequency, within different categorical predictor values, were examined using ANOVA models. 44 incidents were identified; averaging 5.2 articles per decedent. Univariate analyses showed significant difference in media reporting by poverty level (low versus high socioeconomic status) and presence of preceding argument. Multivariate analyses found significantly more media reports (p = 0.002) for incidents in which a preceding argument is reported, the victim was 30-39 years old and from a low socioeconomic status zip code. From our results certain characteristics of IPH are associated with greater media reporting. Promotion of consistent and responsible IPH media reporting guidelines is an opportunity to reinforce public health messaging and dispel myths. In turn, this will encourage the development of future policies and funding streams across the spectrum of preventing and stopping IPV.
