Description:

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.

Variables:

Data frame with 117 observations on the following variables.

• age subject age at baseline (in years)

• anysub use of any substance post-detox: a factor with levels no yes

• cesd Center for Epidemiologic Studies Depression measure of depressive symptoms at baseline (higher scores indicate more symptoms)

• d1 lifetime number of hospitalizations for medical problems (measured at baseline)

• daysanysub time (in days) to first use of any substance post-detox

• dayslink time (in days) to linkage to primary care

• drugrisk Risk Assessment Battery drug risk scale at baseline

• e2b number of times in past 6 months entered a detox program (measured at baseline)

• female 0 for male, 1 for female

• sex a factor with levels male female

• g1b experienced serious thoughts of suicide in last 30 days (measured at baseline): a factor with levels no yes

• homeless housing status: a factor with levels housed homeless

• i2 maximum number of drinks (standard units) consumed per day, in the past 30 days (measured at baseline)

• avg_drinks average number of drinks (standard units) consumed per day, in the past 30 days (measured at baseline). Same as i1.

• max_drinks maximum number of drinks (standard units) consumed per day, in the past 30 days (measured at baseline). Same as i2.

• id subject identifier

• indtot Inventory of Drug Use Consequences (InDUC) total score (measured at baseline)

• linkstatus post-detox linkage to primary care (0 = no, 1 = yes)

• link post-detox linkage to primary care: no yes

• mcs SF-36 Mental Component Score (measured at baseline, higher scores are better)

• pcs SF-36 Physical Component Score (measured at baseline, higher scores are better)

• pss_fr perceived social support by friends (measured at baseline)

• racegrp race/ethnicity: levels black hispanic other white

• satreat any BSAS substance abuse treatment at baseline: no yes

Details

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 dataset is a superset of the HELPrct data with 17 subjects with partially observed data on some of the baseline variables. This is a subset of the HELPfull data which includes 5 timepoints and many additional variables.
