Who Arca is for.
Arca's lead buyers are risk-bearing oncology groups and the health plans that delegate to them. They carry the cost when treatment stalls, and they run or contract with the practices where the decision is made. Cancer programs of every kind work from the same decision record. Four kinds of organization first, then the people inside them.
The risk-bearing physician group
An oncology group or IPA holding capitation or episode risk, where the acute-care events land on the group's own ledger.
What coordination looks like thereThe group runs care management for its oncology population: nurses on the phone, admission alerts from the health plans, and a monthly reconciliation against claims that arrive months late.
Where it breaksThe events the group is at risk for, the dehydration admission, the missed start, the ED visit a callback would have caught, happen between the touchpoints, and the claims feed announces them long after they cost money.
The first boards on ArcaThe managed population's cases on boards and task lists, so treatment starts, referral loops, and going-quiet flags surface as they happen. The monthly evidence pack computes from the same record.
The payer-provider
A health plan that also delivers care, paying coordination fees on one side and staffing navigation on the other.
What coordination looks like thereThe plan side pays per-member-per-month for oncology management and audits the evidence. The delivery side runs the boards and the navigators. Two teams measure coordination two ways, and neither trusts the other's spreadsheet.
Where it breaksThe health plan pays for activity it can't see, and the delivery side does work it can't prove. Every reconciliation is a negotiation.
The first boards on ArcaOne record both sides read: navigation activity, treatment timelines, and closed loops for the covered population, computed from decision records rather than attested in a spreadsheet.
The community cancer program
A CoC-accredited program at a community hospital or a multi-site group: four to eight boards, two or three navigators, one registrar.
What coordination looks like thereThe boards meet weekly. The coordinator builds agendas from emails and chases pathology the day before. Navigation runs on one very good spreadsheet, and the presentation-rate evidence gets assembled by hand before each survey.
Where it breaksThe spreadsheet's owner goes on vacation. A recommendation with no owner surfaces eight months later in a chart review. The survey prep takes three weeks of pulls, and leakage shows up in the referral data after the quarter closes.
The first boards on ArcaThe two busiest boards first, usually GI and breast: agenda, briefs, capture at the table, and the navigator's task list. The accreditation export comes with them.
The academic medical center
A dozen or more site-specific boards, fellows presenting, research protocols in the room, and volumes that fill every agenda.
What coordination looks like thereEach board has its own coordinator, its own template, and its own definition of ready. Prospective presentation is policy; whether it happened is reconstructed for the survey. The service line sees delay data a quarter late.
Where it breaksPresentation criteria, capture quality, and follow-through vary by coordinator, and no one view spans the program. The referral loop back to community physicians is the loudest complaint the network office hears.
The first boards on ArcaTwo boards with different personalities, one surgical and one medical, to prove the capture works in both rooms, then the program view across them: closure, time to treatment, and flags by board.
What changes for each role.
Every one of them needs the same treatment decision, and today each rebuilds it from the minutes, the chart, or a phone call.
RoleWhat they carry todayWhat Arca gives them
Cancer committee chairRuns the board on memory and minutes; finding out what became of a recommendation takes a chart review.Structured decisions with owners, and last month's follow-through on screen at this month's meeting.
Medical oncologistPresents cases from six open tabs; the outside pathology is on a fax somewhere.One brief per case: pathology, imaging, staging, prior presentations, assembled before the meeting.
Nurse navigatorKeeps the plan alive in a personal spreadsheet, callbacks, and sticky notes.One task list across every board, with due dates, and flags for the cases going quiet.
Tumor board coordinatorChases slides and reports the week of the meeting; builds the agenda by hand.An agenda that fills from staged cases and names what each held case is waiting on, days ahead.
Cancer registrarRe-derives the board's decision months later from minutes and notes.The decision written down at the table; the abstract starts filled.
Quality & accreditation leadAssembles presentation-rate evidence by hand before every survey.Presentation rate and prospective share by board, computed from the record, exportable.
VP oncology / service line leaderLearns about leakage and delays from the quarterly, after the quarter.Time to treatment, referral completion, and open flags by site, monthly and current.
CFOCoordination is a cost center whose output has never been measured.The measurement that CMS coordination payments and health plan programs are paid against.
Health plan / IPA medical directorReviews authorization requests one at a time to learn what the practice already decided, and sees the episode in claims six months later.For delegated populations: the documented, pathway-checked treatment plan with its evidence, and treatment starts as they happen.
Referring physicianSends the patient in and hears back at the next office visit, from the patient.The board's recommendation and the plan's status, returned to the practice.
