Study Details:

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.

Study Methodology

Mode of data collection: 
record abstracts
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.
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.
  • 2008-12-15: New files were added. These files included one or more of the following: Stata setup, SAS transport (CPORT), SPSS system, Stata system, SAS supplemental syntax, and Stata supplemental syntax files, and tab-delimited ASCII data file. Some other minor edits were made to improve the data and documentation.
  • 2006-01-18: File CB2347.ALL.PDF was removed from any previous datasets and flagged as a study-level file, so that it will accompany all downloads.
Extent of processing: 
  • 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.
