Hawaii's Opportunity Probation with Enforcement (HOPE)
First Circuit Court, State of Hawaii / RAND Corporation · Honolulu, HI, USA · 2004 · Public Safety
Effect: HOPE vs. control: positive drug tests −72%; missed appointments −61%; new arrests −55%; days incarcerated −48% (fewer revocations meant less jail time overall despite more frequent brief sanctions)
- Positive
IMPACT Collaborative Care for Late-Life Depression
University of Washington / RAND / multiple health systems · United States · 2002 · Public Health
Effect: Depression-free days: +115 days over 24 months vs. usual care; clinical response at 12 months: 45% vs. 19%; quality-adjusted life year difference: 0.26 QALYs; cost-effective at $500 per QALY gained
- Positive
Drug Courts — Randomized Trial Evidence Base
National Institute of Justice / RAND Corporation / multiple jurisdictions · Multiple US cities · 1997 · Public Safety
Effect: Recidivism: −8 to −14 pp vs. standard prosecution in RCTs; drug use: significant reduction while in program, mixed evidence of persistence; incarceration days: substantially fewer during supervision period; cost savings: $3,000–$13,000 per participant vs. incarceration
- Mixed
RAND Health Insurance Experiment
RAND Corporation · United States (6 sites) · 1974 · Public Health
Effect: Free care group used 30% more services than 95% co-insurance group; no significant health outcome differences for average participants; poor and sick patients on free care had meaningfully better blood pressure and vision outcomes
- Mixed
RAND Health Insurance Experiment
RAND Corporation · Multiple US cities · 1971 · Public Health
Effect: Utilization: free care participants used 30–40% more health care than those in high-cost-sharing plans. Health outcomes: almost no significant difference across cost-sharing levels for the average person, except for the poorest and sickest individuals — for whom free care meaningfully improved blood pressure and vision outcomes. Free care improved low-income hypertension control by 10 percentage points.
