Summary
What do they do? SFCCC’s Street Outreach Services describes mobile healthcare, including wound care. This does not establish a sustained venous-ulcer protocol. The model is for clinically assessed, eligible venous disease—not every wound or swollen leg. Federal health-center funding and other clinical providers must be reconciled. More
Why this approach interests us
- Sustained, appropriate venous-ulcer care may produce more time without an ulcer.
Our main reservations
- The treatment trial improved ulcer-free time but not generic health utility. Local protocol and course delivery are unverified.
What do you get for your dollar?
Our provisional best estimate is $24,677,966 per better life:10 additional QALYs. This is a narrow, highly uncertain health-only model, not the organization’s overall impact or a verified donation offer. Inspect the assumptions →
- best guess
- $24,677,966 — USD/10 incremental QALYs; conditional donor budget
- positive scenarios
- $550,265–$5,200,000,000 — Joint scenarios, not confidence intervals
- health evidence
- Null is plausible — A positive best guess does not rule out no added health
- funding room
- Unverified — Public contracts are not marginal donation offers
1. What do they do?
SFCCC’s Street Outreach Services describes mobile healthcare, including wound care. This does not establish a sustained venous-ulcer protocol. The model is for clinically assessed, eligible venous disease—not every wound or swollen leg. Federal health-center funding and other clinical providers must be reconciled.
Verify clinical eligibility
Diagnosis and vascular assessment precede treatment; inappropriate compression in arterial disease can harm.
Fund the complete pathway
Budget weekly care while ulcerated plus aftercare and recurrence prevention, rather than borrowing full-course efficacy for twelve contacts.
Compare actual usual care
Measure health and harms beyond existing services. Offer-level trial effects already contain uptake; do not multiply another generic completion factor.
Scope of this review. Count each patient pathway once. Do not add mortality, housing, substance-use treatment or other overlapping benefits without separate causal models and reconciliation.
2. Monitoring and information sharing
233 eligible patients; mean age about74
Morrell1998 randomized clinical bundle. 5.9 additional ulcer-free weeks over one year; generic EuroQol/SF36 difference absent.
Our assessment. Weekly treatment while ulcerated, then stockings/review. Arterial disease excluded. Weeks already incorporate recurrence; no extra recurrence credit.
Healed and nonhealed venous-ulcer respondents
Small observational health-state comparison. Wong2023 .870 versus.812, p=.39; noncausal and imprecise.
Our assessment. The .05 central and .16 favorable utility gaps are judgments, not established causal effects.
3. Qualitative assessment
Sustained, appropriate venous-ulcer care may produce more time without an ulcer.
Key reservations
- Existing usual care may already deliver effective compression. Clinic location alone is not the active ingredient.
- A short twelve-contact pilot cannot inherit the complete one-year package effect without a separate model.
- No sepsis, amputation or mortality credit is inferred from generic wound-treatment encounters.
Benefits not included in our estimate
- Healthcare savings as donor cash
- Unmodeled mortality reduction
- Independent housing and substance-use benefits
- Unpriced public or volunteered resources
4. What do you get for your dollar?
$24,677,966 per10 QALYs
Central gross donor cost isUSD3,500 for a full-year pathway.5.9 extra ulcer-free weeks /52 ×.05 assumed utility ×.5 transfer ×.5 financing gives .00141827 QALY. The utility bridge is judgmental; the trial did not demonstrate a generic utility advantage.
A better life is our comparison unit of 10 additional quality-adjusted life years (QALYs), potentially spread across people. These are uncertain estimates, not measured returns or verified donation offers.
How we calculate the estimate
DOLLARS PER BETTER LIFE: 10 ×course cost / {financing × [ulcer-free weeks /52 ×utility gap ×transfer −extra net harm]}
$24,677,966 per10 QALYs
Model inputs and assumptions
- Donor full-course cost judgment
- 3500 (range: 1000 / 3500 / 6000). Range order: favorable / central / pessimistic. No verified local marginal price. Analyst judgment.
- Additional ulcer-free weeks within one year
- 5.9 (range: 10.5 / 5.9 / 1.2). Range order: favorable / central / pessimistic. No verified local marginal price. External study anchor; not local effect.
- Causal utility gap judgment
- 0.05 (range: 0.16 / 0.05 / 0.02). Range order: favorable / central / pessimistic. No verified local marginal price. Analyst judgment.
- Clinical context transfer
- 0.5 (range: 0.75 / 0.5 / 0.1). Range order: favorable / central / pessimistic. No verified local marginal price. Analyst judgment.
- Additional delivery attributable to financing
- 0.5 (range: 0.75 / 0.5 / 0.25). Range order: favorable / central / pessimistic. No verified local marginal price. Analyst judgment.
- Extra net harm per additional course
- 0 (range: 0 / 0 / 0). Range order: favorable / central / pessimistic. No verified local marginal price. Analyst judgment.
Hypothetical course budget—not a verified funding tranche
- Favorable full-course: $550,265 per10 QALYs. 0.01817 conditional QALY per offered course.
- Central: $24,677,966 per10 QALYs. 0.001418 conditional QALY per offered course.
- Pessimistic: $5,200,000,000 per10 QALYs. 0.00001154 conditional QALY per offered course.
Uncertainty. Zero actual utility benefit, unchanged care or fully replaced financing gives no finite positive price. Net harms can make health negative; this is not a negative-price bargain.
5. Funding and previous grants
Need a named clinically eligible cohort, additional capacity, all payer contributions and measured health difference versus actual usual care.
Constructed course:32 planned contacts ×(.5 RN hour ×USD100 ×1.3 loading +USD30 supplies) +USD460 assessment/aftercare/travel/admin =3,500.32 is a planning proxy, not an observed visit count. The460 allowance needs itemization; volunteer/public resources and failed outreach require verification. No donor quote.
This review does not establish a verified marginal funding offer or a complete history of grants.
