Client Outcomes: Real Data From Lantana Recovery

Lantana Recovery tracks clinical outcomes and client-experience feedback across both our Charleston, SC and New Milford, CT locations. The figures below are current as of Q2 2026, sourced directly from clinical assessments, program data, and voluntary discharge surveys — not a one-time report. Every figure here discloses its sample size and time period, including the ones that aren't perfect.

Clinical outcomes

Measured using PHQ-9 (depression) and GAD-7 (anxiety) assessments administered at admission and at follow-up visits.

• Anxiety (GAD-7) improvement: Charleston clients averaged a 25.6% reduction in anxiety symptoms from admission to last follow-up (n=334 matched pairs); New Milford clients averaged a 16.5% reduction (n=49 matched pairs).
• Depression (PHQ-9) improvement: Charleston averaged a 35.9% reduction in depression symptoms (n=334); New Milford averaged a 19.2% reduction (n=49).
• Length of stay: Programming is dosed to each client's clinical needs, not a fixed timeline. Insurance authorization is a major factor, but it isn't what drives our care decisions — in practice, PHP typically runs 4–6 weeks and IOP typically runs 6–8 weeks.
• Step-down to IOP: 32% of Charleston PHP clients and 26% of New Milford PHP clients transitioned into IOP as the next phase of their continuum of care. Not stepping down to IOP doesn't mean a client needed a higher level of care — many complete PHP and continue with standard outpatient care, or conclude treatment at that point.

Based on self-reported clinical assessments (PHQ-9/GAD-7) administered at admission and follow-up visits. Individual results vary.

Q2 2026 program highlights

Charleston, SC

• 70% PHP completion rate (51 of 73 admissions) — well above the 42.6% national treatment-completion average reported in SAMHSA's Treatment Episode Data Set (TEDS 2023).
• 12% left against medical advice, with a median 32-day length of stay for clients who completed — a genuine full course of care, not a brief stay.
• 72% completion rate among clients in Charleston's supported sober-living housing during PHP (n=67) — above the 45–50% national completion range for residential substance use treatment reported in SAMHSA's Treatment Episode Data Set.
• Completion rates held steady across every primary therapist and recovery manager on the Charleston team — a consistent, team-wide standard of care rather than a result driven by any one person.
• Only 5.5% of Charleston PHP clients required referral to a higher level of care while in the program.

New Milford, CT

• 82% completion rate among clients who commuted to treatment rather than staying in program housing, with zero referrals to a higher level of care and zero administrative discharges (n=11) — well above the 37–50% national completion range for outpatient substance use treatment reported in SAMHSA's Treatment Episode Data Set.
• 75% completion rate among clients who stepped down from PHP to IOP (6 of 8) — reaching that step-down is protective for long-term engagement.
• 21.4% of New Milford PHP clients required referral to a higher level of care while in the program.

What clients say at discharge

Based on voluntary client-experience surveys completed at discharge between December 2024 and August 2026 (386 Charleston respondents) and April 2025 and August 2026 (71 New Milford respondents). Results are self-reported and reflect clients who completed the survey, which may not represent every client's experience.
