Health Evaluation and Linkage to Primary Care
The HELP study was a clinical trial for adult inpatients recruited from a detoxification unit. Patients with no primary care physician were randomized to receive a multidisciplinary assessment and a brief motivational intervention or usual care, with the goal of linking them to primary medical care.

treatrandomized to HELP clinic:
Eligible subjects were adults, who spoke Spanish or English, reported alcohol, heroin or cocaine as their first or second drug of choice, resided in proximity to the primary care clinic to which they would be referred or were homeless. Patients with established primary care relationships they planned to continue, significant dementia, specific plans to leave the Boston area that would prevent research participation, failure to provide contact information for tracking purposes, or pregnancy were excluded.
Subjects were interviewed at baseline during their detoxification stay and follow-up interviews were undertaken every 6 months for 2 years. A variety of continuous, count, discrete, and survival time predictors and outcomes were collected at each of these five occasions.
This data set is a subset of the
HELPmiss data set restricted to
the 453 subjects who were fully observed on the
sexrisk variables. (There is some missingness in the other variables.)
HELPmiss contains 17 additional subjects with
partially observed data on some of these baseline variables. This is
also a subset of the
HELPfull data which includes 5 timepoints and
many additional variables.
HELPrct data set was originally named
HELP but has
been renamed to avoid confusion with the
