Washington, DC, Metropolitan Area Drug Study (DC*MADS), 1992: Drug Use Among DC Women Delivering Live Births in DC Hospitals (ICPSR 2347)

Alternate Title:  DC*MADS, 1992 (Live Births)

Principal Investigator(s):


The Washington, DC, Metropolitan Area Drug Study (DC*MADS) was conducted in 1991, and included special analyses of homeless and transient delivering live births in the DC hospitals. DC*MADS was undertaken to assess the full extent of the drug problem in one metropolitan area. The study was comprised of 16 separate studies that focused on different sub-groups, many of which are typically not included or are underrepresented in household surveys.

The DC*MADS: Drug Use Among Women Delivering Livebirths in DC Hospitals was designed to examine the nature and extent of drug use among women delivering live births in eight Washington, DC, hospitals participating in the study. Data from the questionnaires include prenatal care, health problems during pregnancy, pregnancy drug use history, needle use, polysubstance use, patterns of use, respondent's general experiences with drug use, including perceptions of the risks and consequences of use, occurrence of psychological and emotional problems, income and insurance coverage, treatment experiences, and maternal and infant outcomes. Medical records were abstracted from the women and their infants to document medical problems. Abstracted data on the mothers included demographics, discharge diagnoses, disposition at discharge, and results of urine screens. Abstracted data on infants included delivery information, status at discharge, discharge diagnoses/procedures, and first urine toxicology screen results.

Sample:   Eight of nine Washington, DC, hospitals participated in the study. Eligible respondents were women delivering live births in participating hospitals during a given period. High-risk women, defined as those giving birth to low birth weight or pre-term infants or those admitting to drug use, were oversampled.

Mode of Data Collection:   record abstracts, face-to-face interview

Data Source:

personal interviews and medical records

Response Rates:   The interview response rate was 86.7 percent. Of those interviewed, 68.8 percent agreed to have medical records abstracted for themselves and their infants, resulting in an abstraction response rate of 59.7 percent.

Extent of Processing:  ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Performed consistency checks.
  • Created variable labels and/or value labels.
  • Standardized missing values.
  • Created online analysis version with question text.
  • Performed recodes and/or calculated derived variables.
  • Checked for undocumented or out-of-range codes.

Restrictions: Users are reminded by the United States Department of Health and Human Services that these data are to be used solely for statistical analysis and reporting of aggregated information and not for the investigation of specific individuals or treatment facilities.
