Watchful Waiting and Safety-Netting in Suspected Paediatric Appendicitis: No “Mandatory Referral” Where GP Acts with Ordinary Care

1) Introduction

Afolabi v Southdoc Services Ltd and Anor (Approved) [2026] IEHC 110 is a High Court clinical negligence decision arising from an out-of-hours GP consultation on 13 December 2017 at SouthDoc. The plaintiff, Maria Afolabi (then aged 11), attended with abdominal pain, vomiting and later diarrhoea. The second defendant, Dr. Rachel Finnegan, examined her and diagnosed likely gastroenteritis, provided conservative advice, “red flag” (safety-net) guidance, and a hospital referral letter which included the handwritten caution “Cave appendicitis”.

The plaintiff alleged negligent failure to diagnose appendicitis and to refer immediately to hospital, contending that a delay led to perforation and serious complications including laparotomy, infection, prolonged admission and permanent scarring. The defendants maintained that the diagnosis and management were reasonable and that, in any event, the mother did not act on the safety-net advice and referral letter when the child deteriorated.

The judgment is significant for its clear rejection of a pleaded/advanced notion that once appendicitis is within the differential diagnosis, immediate hospital referral is mandatory. The Court endorses a GP “watchful waiting” approach with appropriate safety-netting, on the facts found.

2) Summary of the Judgment

  • Diagnosis: The Court held Dr. Finnegan’s primary diagnosis of likely gastroenteritis was reasonable.
  • Management: The Court accepted that Dr. Finnegan provided appropriate conservative management, red flag advice, and a referral letter “if any deterioration”.
  • Standard of care: The Court preferred the defence evidence that “watchful waiting” is a legitimate GP tool and rejected the plaintiff expert’s “mandatory referral” approach as unworkable.
  • Causation (addressed notwithstanding no breach): The Court found it likely that even if the plaintiff had attended ED on 13 December 2017, she would likely have been discharged with similar safety-netting; earlier attendance on 14/15 December would probably have avoided laparotomy.
  • Outcome: The claim was dismissed.
  • Costs: Defendants awarded costs pursuant to S169 of the Legal Services Regulation Act 2015 (“costs follow the event”).

3) Analysis

3.1) Precedents Cited

Dunne v National Maternity Hospital [1989] IR 91

The Court applied the classic Irish test for medical negligence as stated by Finlay CJ, including that negligence is established only where the practitioner is guilty of a failure such that no practitioner of equal status and skill, acting with ordinary care, would be guilty of; and that the Court is not to choose between two reasonable schools of practice. This framework shaped the decision in two ways:

  1. Deference to a reasonable range of GP practice: The Court treated the dispute between “mandatory referral” and “watchful waiting” as a dispute about acceptable clinical approaches. On the evidence accepted, “watchful waiting” with safety-netting fell within a permissible range of careful practice.
  2. Focus on whether the plaintiff displaced a general/approved practice: The defence position—conservative management with red flag advice and a conditional referral letter—was treated as standard practice. The plaintiff did not establish that this practice had “inherent defects” obvious on due consideration.

Morrisey v HSE [2020] IESC 6

Cited to confirm that the applicable standard is that of a medical professional of equal status acting with ordinary care. The citation reinforced that the Court’s task is not hindsight evaluation but determining whether the defendant’s approach met the ordinary-care standard at the time, based on accepted facts and contemporaneous documentation.

3.2) Legal Reasoning

(a) Fact-finding: primacy of contemporaneous records and plausibility

Central factual disputes concerned mobility (“unable to stand”), the “bed test”, the extent of tenderness, and whether appendicitis concerns were “shot down”. The Court attached greater weight to Dr. Finnegan’s contemporaneous note (“looks well able to get on couch”) and the referral letter expressly recording “Cave appendicitis”. That documentation made it difficult to reconcile the plaintiff’s account (that appendicitis was dismissed “out of hand”) with what was recorded at the time. The Court also expressed concern about the reliability of aspects of the mother’s evidence, noting how the “confusing handwritten note” point only emerged in updated particulars shortly before trial.

(b) Breach: rejecting “mandatory referral” and endorsing safety-netting/watchful waiting

Having found the diagnosis of gastroenteritis reasonable (and noting the GP experts’ common ground on that point), the key question became management: whether ordinary care required immediate hospital referral that evening. The Court preferred the defence GP evidence that GPs must use “time as a tool” and cannot refer every case where a serious condition cannot be fully excluded in primary care. On the accepted clinical picture—settling vomiting, onset of diarrhoea, soft abdomen with only mild generalised tenderness, no rebound/guarding, normal pulse, low-grade temperature—an immediate ED referral was not mandated.

The Court accepted that red flag advice was given and that a conditional referral letter was provided for deterioration. The plaintiff’s case depended heavily on disproving safety-netting and establishing that the only safe option was immediate referral; the Court found neither made out on the facts and expert evidence.

(c) Causation: even if earlier ED attendance, likely discharge; later ED attendance could have avoided laparotomy

Although unnecessary given the no-breach finding, the Court addressed causation. It accepted defence emergency medicine evidence that, on 13 December 2017, the plaintiff would likely have been triaged, had blood tests that may have been normal, and been discharged with return advice. It further accepted evidence suggesting perforation likely occurred later (around 15 December), and that presentation on 14/15 December probably would have led to appendectomy without laparotomy and its sequelae. This dovetailed with the Court’s conclusion that the critical avoidable delay was the failure to act on deterioration using the safety net/referral route.

3.3) Impact

  • Primary care discretion preserved: The decision provides a clear High Court endorsement that where appendicitis is merely a differential diagnosis in a GP setting—without hospital-level diagnostics—immediate referral is not automatically required, provided ordinary-care assessment and safety-netting are in place.
  • Safety-netting as a litigation focal point: Documentation of red flag advice and the content of referral letters (including wording like “Cave appendicitis”) can be determinative in resolving disputes about what was said and whether escalation routes were provided.
  • Causation remains a separate hurdle: Even where an earlier referral might be argued, the Court’s analysis illustrates that plaintiffs must still prove that earlier attendance would probably have changed outcome (e.g., admission, diagnosis, non-perforated surgery), not merely that it was possible.
  • Pleadings discipline: The Court’s observation that a key contention (confusion caused by the handwritten note) “was never pleaded” until late may encourage tighter alignment between evolving evidence and formal pleadings in clinical negligence litigation.
  • Costs exposure: The award of costs under S169 of the Legal Services Regulation Act 2015 underlines the financial risk where claims fail after a full trial, particularly where factual disputes turn on contemporaneous records.

4) Complex Concepts Simplified

  • “Differential diagnosis”: a list of possible conditions that could explain symptoms. A condition can be on the list without being the most likely.
  • “Cave appendicitis”: Latin shorthand meaning “beware of appendicitis”—a caution that appendicitis remains a possibility.
  • “Red flag” / “safety-netting” advice: clear instructions on what worsening symptoms (e.g., worsening pain, persistent vomiting, fever, deterioration) should trigger urgent re-attendance or hospital review.
  • Dunne standard: the Court does not decide the “best” medical approach; it decides whether the defendant’s approach fell outside what any ordinary-care peer would do.
  • Causation: even if care was substandard, the plaintiff must show the substandard act probably caused the injury complained of (not just that it might have).
  • CRP and “doubling time”: CRP is an inflammation marker that can rise over time; retrospective modelling of earlier CRP levels is uncertain and was treated as of limited value unless aligned with clinical features and operative/pathological findings.
  • Alvarado score / Paediatric Appendicitis Score (PAS): scoring tools used mainly in hospital settings to estimate appendicitis likelihood; their retrospective application in this GP-to-ED counterfactual was contested.

5) Conclusion

The High Court dismissed the claim, holding that Dr. Finnegan’s diagnosis of likely gastroenteritis and her management—conservative treatment with safety-netting and a conditional hospital referral letter—met the Dunne v National Maternity Hospital [1989] IR 91 ordinary-care standard as reaffirmed in Morrisey v HSE [2020] IESC 6. The judgment’s central takeaway is that, on appropriate facts, a GP may legitimately adopt “watchful waiting” even where appendicitis is considered, and that well-documented safety-netting and referral pathways can be decisive both on breach and on the later causation narrative.
