# Liability and Economic Assessment — Orr v. North Vale Hospital

## 1. Breach

The duty element is uncontested: an emergency physician–patient relationship existed. Breach is supported by a board-certified emergency physician's signed preliminary opinion that failure to obtain immediate surgical consultation after an MRI reporting a probable spinal epidural abscess violated the standard of care.

The documentary record is unusually strong for a breach case. The MRI report is timestamped 11:18 p.m., it expressly recommended *immediate* surgical consultation, and the physician *electronically acknowledged* it. The call to surgery was not placed until 7:30 a.m. — a documented 8-hour, 12-minute gap between acknowledged notice and any action. The acknowledgment is machine-generated, so the usual "I never saw the report" defense is foreclosed. Expert testimony is still required (this is a professional-judgment matter, not one within ordinary lay knowledge), but the expert has only to characterize a delay the metadata already proves.

**Assessment: breach is the strongest element of the case.**

## 2. Causation under the greater-than-50-percent rule

The neurosurgeon opines that decompression **before 2:00 a.m.** would have given Lena a **60 percent probability** of avoiding permanent neurological deficit. Sixty percent exceeds the governing threshold: this is a more-likely-than-not opinion, not a "lost chance" or "mere possibility" opinion, and it therefore satisfies Rule 2 as pleaded.

Two cautions:

**(a) The intermediate factual link.** The 60 percent figure is conditioned on surgery *before 2:00 a.m.* The expert does not supply that step; the record must. Plaintiff must prove that a call placed at ~11:20 p.m. would in fact have produced decompression within roughly 2.5 hours. That requires the on-call surgeon's schedule, OR availability and staffing that night, anesthesia logs, and the hospital's own response-time policy for suspected epidural abscess. If the realistic earliest surgical time was 3:00 or 4:00 a.m., the 60 percent opinion no longer applies on its own terms and causation may collapse below 50 percent. **This is the single most important investigative task, and it should be resolved before large cost outlays.**

**(b) The margin is thin.** Sixty percent clears the bar by ten points. The anticipated defense — that sepsis and abscess location made the deficit inevitable — attacks precisely this number. It goes to weight rather than admissibility, but it is the reason the panel's success probability is 55 percent rather than 75 percent.

## 3. Does the preliminary record support filing?

Yes. Rule 3 requires an expert certificate with the complaint, and the firm needs both an emergency-medicine standard-of-care opinion and a neurosurgical causation opinion. Both experts are identified, both have signed preliminary opinions, and both will convert to formal certificates within 20 days of retention. Nothing further is required to file.

## 4. Conditional expected verdict

| Branch | Probability | Verdict | Contribution |
|---|---|---|---|
| Low | 60% | $1,200,000 | $720,000 |
| Mid | 30% | $2,400,000 | $720,000 |
| High | 10% | $4,000,000 | $400,000 |
| **Expected verdict \| plaintiff win** | | | **$1,840,000** |

## 5. Lena's net recovery by branch

Order of operations under the proposed agreement: costs ($240,000) reimbursed first → fee is one-third of the remainder → lien ($160,000) paid from Lena's share.

| | $1,200,000 | $2,400,000 | $4,000,000 |
|---|---|---|---|
| Gross verdict | $1,200,000 | $2,400,000 | $4,000,000 |
| Less costs | (240,000) | (240,000) | (240,000) |
| Net after costs | 960,000 | 2,160,000 | 3,760,000 |
| Attorney fee (⅓) | (320,000) | (720,000) | (1,253,333) |
| Client remainder | 640,000 | 1,440,000 | 2,506,667 |
| Less hospital lien | (160,000) | (160,000) | (160,000) |
| **Lena's net** | **$480,000** | **$1,280,000** | **$2,346,667** |

Every branch clears costs plus lien, so there is no branch in which Lena nets zero or the firm goes unreimbursed after a win.

## 6. Lena's overall expected net recovery

Conditional on winning: (0.60 × $480,000) + (0.30 × $1,280,000) + (0.10 × $2,346,667) = $288,000 + $384,000 + $234,667 = **$906,667**.

Unconditional: 0.55 × $906,667 = **$498,667**.

(Cross-check: $1,840,000 − $240,000 − $533,333 − $160,000 = $906,667. ✓)

## 7. Firm's expected fee and expected unreimbursed costs

**Expected fee:** conditional fee = ($1,840,000 − $240,000) ÷ 3 = $533,333. Unconditional: 0.55 × $533,333 = **$293,333**.

**Expected unreimbursed costs:** costs of $240,000 are incurred in all events. On a win they are fully reimbursed off the top (every verdict exceeds $240,000). On a loss (45 percent) the firm absorbs them entirely and charges Lena nothing (Rule 7). Expected loss = 0.45 × $240,000 = **$108,000**.

## 8. Expected net return against intake policy

$$\$293{,}333 - \$108{,}000 = \boxed{\$185{,}333}$$

The policy floor is $175,000. The case clears it by **$10,333 — a cushion of about 5.9 percent.** That is a pass, but a narrow one, and the sensitivity analysis matters:

- **Cost tolerance.** Net return = $337,333 − 0.6333 × (costs). The policy fails once costs exceed **$256,316** — roughly a 6.8 percent overrun. A single extra expert, a second causation deposition abroad, or a Daubert-style challenge requiring supplemental work can consume that.
- **Probability tolerance.** Net return = p × $533,333 − (1 − p) × $240,000. The policy fails once success probability drops below **53.7 percent**. The panel's 55 percent leaves 1.3 points of headroom.

Both margins turn on the same fact: whether surgery before 2:00 a.m. was actually achievable. That inquiry is cheap and should be front-loaded.

## 9. Filing and certificate timetable

| Event | Day |
|---|---|
| Today | 0 |
| Signed certificates from both experts | 20 |
| **Policy filing deadline (30 days before limitations)** | **80** |
| Limitations expires | 110 |

Certificates arrive on Day 20, sixty days before the Day-80 policy deadline and ninety days before the statutory bar. The policy's timing condition is satisfied with a wide margin. Because Rule 3 forbids any extension for ordinary law-office delay, the internal target should be filing by **Day 35–40**, not Day 80, preserving forty-plus days of slack for a recalcitrant expert, a records gap, or a defendant-identification problem.

## 10. Recommendation: **ACCEPT**, with cost discipline as a condition

Both intake criteria are met: expected net return of $185,333 exceeds the $175,000 floor, and the case can be filed with both required expert certificates well before the 30-day cushion. Breach is documented by machine timestamps; causation is supported by a 60 percent more-likely-than-not opinion; every verdict branch leaves the client a substantial net recovery.

The acceptance should be conditioned on a hard cost budget, because the economic margin is thin enough that ordinary overruns would have made the case unacceptable had they been forecast at intake.

**First concrete steps:**

1. **Retain both experts today** on written engagement letters requiring signed certificates within 20 days; calendar Day 20 with a hard follow-up at Day 14.
2. **Serve a litigation-hold and evidence-preservation letter immediately** on North Vale Hospital covering EHR audit-trail metadata, the acknowledgment log for the 11:18 p.m. MRI report, paging and telephone records for 11:00 p.m.–8:00 a.m., on-call rosters, OR and anesthesia logs, and the abscess-response policy. Metadata is the case; it must be locked down before any routine purge cycle.
3. **Resolve the 2:00 a.m. feasibility question first.** Obtain the OR/on-call records and have the neurosurgeon confirm in writing that decompression before 2:00 a.m. was achievable on that night's staffing. Treat this as a go/no-go checkpoint before authorizing spending beyond roughly $25,000.
4. **Draft the complaint now** for filing by Day 35–40; do not use the Day-80 or Day-110 dates as working targets.
5. **Set a written cost cap of $250,000** with partner approval required to exceed it, and re-run the intake arithmetic if the panel's 55 percent estimate is revised downward at any point.
6. **Docket the lien.** The $160,000 lien is currently nonnegotiable and does not affect the firm's fee, but it reduces Lena's share dollar-for-dollar; revisit reduction after liability discovery strengthens, and disclose the branch-by-branch net figures in Section 5 to Lena in writing before she signs the fee agreement, so her expectations are set at $480,000 in the most likely winning scenario — not at the headline verdict.
