{"edition":"california","organization":"Operation Access","organizationId":"ein:94-3180356","boundaryVersion":"US-CA-state-v1","updated":"2026-09-13","model":{"version":"ca-oa-finite-whole-portfolio-alpha-v1","costScope":"Full ordinary gift in donor numerator. All ten specialty allocations sum to one and include recipient program, management, fundraising and failed-referral work. Separate gross associated resource sensitivity includes all nominal services, not merely health-credited cases; no waived-charge multiplier. Prospective cash per-service costs are judgments anchored to 2025 recipient cash-like scale.","geographicAttribution":"Current patient eligibility requires residence in Northern California or the Central Valley. Accordingly all modeled direct patient benefit is assigned to California: Q_CA=Q_all. This is a service-eligibility inference, not headquarters/population allocation; no Bay=0.6 or SF=0.08 factor is reused. Migration or secondary spillovers are unmodeled. Geographic nesting means these QALYs must not be summed with the same services' Bay/USA benefits.","formula":"Let F(r,H)=(1-exp(-r*H))/r with F(0,H)=H. For specialty k: nominal S_k=C*a_k/c_k; S=sum S_k; activity A=min(S*f,K)/S. For disjoint diagnosis path j within k: P_j=S_k*s_j*A*d_j/r_j, where s=case share,d=nonoverlap fraction,r=services/person. Symptom Q_j=P_j*[success_j*utility_j*(1+discount)^(-delay_j)*F(catchup_j+loss_j+mortality_j+ln(1+discount),horizon_j)-harm_j]. For CRC let z(t)=delta_hazard*exp(-catchup*latency)*F(catchup,min(max(t-latency,0),active_years)); Δsurvival(t)=exp(-baseline_mortality*t)*(exp(z(t))-1). CRC Q=P_crc*[linkage*surviving_utility*(1+discount)^(-delay)*integral_0^H Δsurvival(t)*(1+discount)^(-t)dt - harm]. Sum CRC, cataract, hernia and all named symptom paths, subtract independent harm once. Q_CA=Q_all; donor_price_10=10*C/Q_CA for positive Q_CA. Full exact parameter vectors and scenario overrides are below. Numeric reproduction uses existing lib/oa-portfolio-model.mjs and lib/oa-portfolio-foundation.mjs; its regions.us.q equals CA here solely because eligibility was independently verified.","counterfactual":"Without a new gift, existing funded OA care and other providers continue. f represents the fraction of nominal activity that is maintained/expanded because of new funds, K capacity; catch-up hazards separately represent patients obtaining equivalent care later. Modern medical management and spontaneous remission remain alternatives. Uninsured at intake does not mean no lifetime access.","attribution":"The all-diagnosis ledger partitions each specialty into shares summing to one; repeat services are converted to people and disjoint fractions discount patient overlap. These fractions are priors, not an audited unique-person ledger. Provider donations are complementary inputs; no additional arbitrary provider-credit multiplier is added after modeling funded additional activity. No extra navigation completion multiplier on already-completed services; no productivity/caregiver benefit or duplicate all-cancer survival gain.","uncertainty":"Conditional scenario model dominated by diagnostic mix, baseline utility, funding additionality and later-care assumptions. Favorable, rapid-catch-up, null and adverse states are deliberately wide stress tests, not probability intervals or empirical bounds. The central input set is a transparent judgment, not an observed expectation. Twenty-one supplementary named paths plus CRC/cataract/hernia cover the full specialty allocation; the small other-assessment path has no central benefit and retains burden.","nativeOutcomes":"Observed 2025: 1,529 procedures and diagnostic services, not unique patients. The central model connects additional service-equivalents to diagnosis-specific symptom relief or survival, allowing for repeated visits, later alternative care and harms. The historical cash-like average is about $1,476 per reported service; it does not establish the price of additional care.","inputs":[{"name":"California direct benefit share","value":1,"unit":"fraction","basis":"judgment","rationale":"Independent current eligibility check requires Northern California or Central Valley residence; residence retention over modeled life course is assumed.","sourceIds":["eligibility"]},{"name":"2025 observed specialty service counts","value":"{\"gi\":575,\"general\":201,\"gyne\":168,\"ortho\":158,\"head_neck\":127,\"urology\":101,\"derm\":80,\"vascular\":58,\"eye\":45,\"other\":16}","unit":"reported services by specialty, not persons","basis":"observed","rationale":"2025 annual report chart text refreshed; diagnosis mapping retained from September9 visual audit.
