Summary

What do they do? La Casa de las Madres, EIN 94-2330864, provides emergency shelter, community advocacy and counseling, police-response follow-up, statewide crisis lines, supportive-housing services and prevention. Its 2025 report describes 1,384 Bay Area survivors of all ages receiving direct services. More

Why this approach interests us

  • Safety-focused advocacy and practical support may reduce abuse and improve short-term health. External intensive post-shelter advocacy trials provide some support for this pathway.

Our main reservations

  • The external intervention differs from La Casa's mixed services. Additionality, advocacy dose, geography and the finite utility bridge are judgments; a 5%-weight favorable world supplies 86.9% of all-beneficiary expected net benefit.

What do you get for your dollar?

A $100,000 ordinary whole-organization gift produces 0.044061 signed prior-weighted Bay QALYs, or $22,695,319 per 10. Across all modeled beneficiaries, the estimate is $22,460,767 donor cash and $26,728,312 modeled gross resources per 10 QALYs. Observed QALYs and verified marginal capacity remain unknown.

1. What do they do?

La Casa de las Madres, EIN 94-2330864, provides emergency shelter, community advocacy and counseling, police-response follow-up, statewide crisis lines, supportive-housing services and prevention. Its 2025 report describes 1,384 Bay Area survivors of all ages receiving direct services.

Connect with safety and support

Survivors reach crisis response, shelter, a community office or partner co-locations.

Receive appropriate advocacy

Only an assumed adult-eligible fraction receiving an intensive-advocacy-equivalent dose enters the health bridge.

Count finite additional benefit

Apply funding additionality and a signed finite QALY effect; other contacts and overlapping programs are not separately added.

Scope of this review. All FY2025 IRS expense of $4,560,661 is charged. The 1,384 direct-service umbrella is non-additive: 885 community-office users, 815 co-location users, 231 sheltered people, 6,571 shelter service-days, 2,226 police contacts and 6,151 calls/texts are not summed. This retains whole-organization costs while leaving non-advocacy health pathways unquantified, not proven zero.

2. Monitoring and information sharing

La Casa's mixed-age direct-service population

Organization-reported FY2025 activity and finances. Annual report gives a broad 1,384 Bay survivor umbrella alongside overlapping service counts and self-reported outcomes.

Our assessment. Outputs establish delivery, not causal QALYs. Do not sum contacts or interpret success surveys as effects versus a counterfactual.

278 former shelter residents receiving ten weeks of advocacy or control

Randomized trial, Sullivan and Bybee. Authors report reduced violence and better quality-of-life-related outcomes across two-year follow-up, with 95% retained.

Our assessment. An intensive post-shelter intervention is not La Casa's whole portfolio. Present-day dose, adult eligibility and response remain uncertain.

Women experiencing intimate partner abuse in varied settings

Systematic review of randomized and quasi-randomized advocacy trials. Intensive advocacy may improve some short-term quality-of-life and abuse outcomes; evidence is heterogeneous, often low quality, and several outcomes include no benefit.

Our assessment. The NNT≈8 at 24 months is not observed QALY gain or proof of two continuous years without abuse. Null and harm priors remain explicit.

Modeled abused and not-abused states, not La Casa participants

UK decision-model state utilities. Utilities used include 0.63 abused/unidentified, 0.65 seeing an advocate and 0.85 not abused.

Our assessment. Combining the 0.22 gap with an advocacy response rate and finite duration is an analyst heuristic; the full gap is not the measured effect of seeing an advocate.

136 women in nine Dutch shelters

Randomized critical-time-intervention trial. At nine months PTSD improved, but primary quality of life and several re-abuse and mental-health outcomes were null.

Our assessment. Different intervention and setting; supports caution rather than supplying a La Casa coefficient.

La Casa housing support and shelter programs

City executed-agreement reporting and draft funding recommendations. Documented Verona support agreement extends through June2027; separate FY2026–27 shelter support is proposed.

Our assessment. Distinguish executed baseline agreements from proposals; neither demonstrates gift-triggered additional capacity.

3. Qualitative assessment

Safety-focused advocacy and practical support may reduce abuse and improve short-term health. External intensive post-shelter advocacy trials provide some support for this pathway.

Key reservations

  • The modeled result is unfavorable and is not a recommendation to give.
  • 86.9% of all-beneficiary expected net QALYs comes from a 5%-weight favorable prior.
  • No observed La Casa QALY effect, verified advocacy-dose mix or marginal funding offer was found.
  • Public funding, other donors and reserves complicate additionality; assets do not establish unrestricted liquid availability.
  • The two-year health bridge assumes persistence not established by a 24-month outcome measurement.
  • Bay and SF shares are unmeasured residence priors; all costs are retained even for unquantified services.
  • In-kind reconciliation and complete external resource costs remain unknown.

Benefits not included in our estimate

  • Mortality prevention and lifetime effects
  • Separate additive hotline, police-response, shelter, prevention and co-location QALYs
  • Child and caregiver health effects beyond the modeled adult advocacy pathway
  • Financial savings, housing value and taxpayer savings as QALYs

4. What do you get for your dollar?

Signed expected Bay cost: $22,695,319 per 10 QALYs

Compute each joint scenario's signed QALYs, weight health outcomes, then divide the whole gift by the weighted result. Do not average prices or discard harmful worlds.

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

CENTRAL ADVOCACY PATHWAY: QBay = (100000 / 4560661) × 1384 × .70 adult-eligible × .20 full advocacy dose × .15 funding additionality × .05 finite QALY × .98 Bay share
Central Bay QALYs = 0.031226; all-beneficiary central donor cost = $31,383,574 per 10 QALYs. The prior-weighted Bay headline is not this central scenario.

Model inputs and assumptions
Whole annual expense
$4,560,661 FY2025 IRS (range: Annual report: $4,525,216). No overhead or non-advocacy cost removed. Reported $95,586 in-kind input is not assumed included in IRS expense or mechanically added. Reported accounting; reconciliation incomplete.
Broad direct-service umbrella
1,384 (range: 885 community-office subset diagnostic). Mixed ages and services; overlapping outputs are not added. Organization-reported, not a verified unique-dose census.
Adult eligibility and full advocacy dose
70% × 20% central (range: Adult share 50–85%; dose 5–50%). External intensive post-shelter advocacy evidence cannot be assigned to every person, child, call or brief contact. Analyst priors.
Funding additionality
15% central (range: 0–40%). Public funding, other gifts, reserves and operational capacity may replace or constrain a gift's additional services. Analyst prior; no marginal offer.
Finite QALY bridge
0.05 per full advocacy equivalent (range: −0.02 harm to 0.15 favorable). 1/8 responders × (0.85−0.63) modeled annual utility gap × 2 years = 0.055, rounded down to 0.05. A 24-month abuse endpoint does not establish continuous two-year remission. Advocate-state utility is only 0.65. The 0.15 tail is a wide judgment, not measured benefit; no mortality credit. Unvalidated cross-study heuristic.
Recipient geography
98% Bay / 85% SF central (range: Bay 90–99%; nested SF 70–95%). Annual report supports Bay presence, not exact residence shares. Statewide hotline receives no direct health credit. Analyst residence priors.
Joint scenario weights
5/25/20/25/20/5% (range: Harm / funding-null / evidence-null / cautious / central / favorable). Null and negative outcomes are retained. Favorable contribution is 86.9% of all-beneficiary weighted net QALYs. Subjective priors, not statistical confidence.
Gross-resource multiplier
1.15 central (range: 1.10–1.50). Intended to encompass unreconciled in-kind and unpriced partner inputs. Verified complete gross resource cost remains unavailable. Sensitivity, not complete accounting.

Illustrative $100,000 ordinary gift

  • harm: Negative Bay health outcome. 5% weight; −0.011470 Bay QALYs. Nonpositive outcomes have no positive cost-effectiveness ratio.
  • funding-null: Zero additional health. 25% weight; funding additionality zero. Full gift cost remains.
  • evidence-null: Zero health effect. 20% weight; the transferred advocacy effect is zero.
  • cautious: 0.000341 Bay QALYs. 25% weight; low adult eligibility, dose and funding additionality.
  • central: 0.031226 Bay QALYs. 20% weight; 0.05 finite QALY per full advocacy equivalent. All-beneficiary central price is $31,383,574 per 10.
  • favorable: 0.766096 Bay QALYs. 5% weight; 0.15 finite QALY per equivalent. All-beneficiary favorable price is $1,292,264 per 10, not a quoted donation offer.
  • favorable contribution removed: $171,517,256 per 10 all-beneficiary QALYs. Original-weight favorable contribution is removed without renormalization; this is the saved model diagnostic, not a Bay ratio.

Uncertainty. The finite bridge combines heterogeneous advocacy and state-utility evidence. Duration, response, eligibility and dose are not measured La Casa effects. No mortality, lifetime or separate additive shelter/prevention benefit is credited. Linear gift scaling is an accounting assumption, not verified large-gift absorption capacity.

5. Funding and previous grants

Establish a priced additional service or preservation plan, its funding counterfactual, unduplicated recipients, advocacy dose and finite health outcomes before recommending a gift.

No verified marginal funding offer. FY2025 IRS revenue is $5,062,993, surplus $502,332 and net assets $13,476,875; assets are not all current unrestricted cash. A city executed-agreement report lists Verona Hotel support services through June2027, total NTE $1,332,681, supporting 65 housing units. A draft FY2026–27 plan recommends $165,000 for shelter/case management; final executed award was not verified. These are baseline funding records, not prices for additional advocacy. Public funding and private gifts overlap; no entire grant is subtracted from whole expense. Promotional $100 shelter-night examples are not binding marginal prices.

This review does not establish a verified marginal funding offer or a complete history of grants.
