Factual and Procedural Background
On 19 February 2014, the Plaintiff, a seriously ill young man newly diagnosed with human immunodeficiency virus ("HIV"), was admitted to The Hospital. During a 42-day admission, The Hospital failed to diagnose visceral leishmaniasis ("VL"), which was later diagnosed after the Plaintiff was transferred to Company B in Spain. The Plaintiff was also diagnosed with hemophagocytic lympho-histiocytosis ("HLH"), triggered by herpes virus type 8 ("HHV-8"), in the context of HIV. The Hospital accepts that none of the five Consultants managing the Plaintiff considered VL as a diagnosis during admission. The central issue is whether The Hospital breached the standard of care by failing to diagnose VL.
Legal Issues Presented
- Should The Hospital have diagnosed VL within four days of the Plaintiff’s admission?
- Alternatively, should The Hospital have diagnosed VL later during the 42-day admission, and if so, when?
- If VL should have been diagnosed, what treatment and recovery would have followed?
- What is the difference between the counterfactual treatment and recovery and what actually occurred?
- What is the appropriate compensation for the difference?
Arguments of the Parties
Plaintiff's Arguments
- The epidemiological association between HIV, VL, and Spain, combined with the Plaintiff’s HIV positive status and Spanish origin, should have alerted clinicians to VL.
- The Plaintiff’s massive splenomegaly was a key diagnostic feature indicating VL.
- The Hospital should have diagnosed VL and commenced treatment with AmBisome within four days of admission.
- Empirical administration of AmBisome was justified on reasonable suspicion of VL.
- Earlier diagnosis and treatment would have led to recovery within approximately five days and discharge within two weeks.
- Instead, the Plaintiff endured six weeks of hospitalisation, chemotherapy, infections, blood transfusions, restricted mobility, intensive care, and ongoing pain and suffering.
- Upon transfer to Spain, VL was diagnosed within three days, treatment commenced, and the Plaintiff recovered sufficiently to be discharged within a week.
Defendant's Arguments
- The Plaintiff’s condition was life-threatening and required urgent diagnosis and treatment.
- The Hospital made a timely and reasonable diagnosis of HLH with credible triggers HIV and HHV-8, and administered appropriate treatment.
- VL was extraordinarily rare in Ireland, never previously encountered by the treating consultants, and was not a breach of care to omit from differential diagnosis.
- Splenomegaly, even massive, is a non-specific sign and does not necessarily indicate VL.
- It was reasonable to allow time for the HLH treatment to work; signs of improvement appeared by mid-March.
- The Plaintiff’s desire to return to Spain was facilitated when he was medically stable enough for transfer.
- The speed of VL diagnosis in Spain was aided by prior investigations and local familiarity with VL, not indicative of breach by The Hospital.

Court's Reasoning and Analysis
The court began by establishing the relevant standard of care under the Dunne principles as restated in Morrissey, focusing on whether no reasonable medical practitioner of similar skill would have acted as The Hospital’s clinicians did. It was undisputed that the clinicians failed to consider VL, but the question was whether this failure breached the standard of care.
The court examined expert evidence from both parties. It accepted that an Infectious Disease ("ID") consultant specializing in HIV should have known, in 2014, of the epidemiological association between HIV and VL in patients from Spain, including the Plaintiff. However, the court found that knowledge of this association alone did not mandate that VL be considered in the differential diagnosis of every HIV positive patient from Spain, especially early in management.
The court rejected the contention that massive splenomegaly was a definitive diagnostic clue for VL, noting conflicting expert opinions and insufficient literature support to make this a required consideration. It emphasized that HLH itself is associated with significant splenomegaly, and that the standard of care permits clinicians to pursue a reasonable working diagnosis supported by credible triggers.
The court further held that clinicians must keep diagnoses under review and reconsider them in light of developments. It found that by no later than 14 March 2014, when the Plaintiff’s HHV-8 levels were negative, treatment had not yielded expected improvement, and his condition worsened, a reconsideration of the diagnosis including suspicion of VL was required. The court identified the period between 10 and 14 March 2014 as the critical window when suspicion of VL should have arisen, prompting empirical treatment with AmBisome.
Regarding causation, the court accepted that earlier diagnosis and treatment with AmBisome would likely have led to symptomatic improvement within a week and substantial recovery within two weeks, sparing the Plaintiff approximately three weeks of debilitating symptoms and hospitalisation. However, it found that it was not negligent for The Hospital to fail to diagnose or treat VL prior to this critical period, given the complexity and rarity of the condition in Ireland.
On damages, the court noted the Plaintiff made a full recovery with no long-term sequelae attributed to the delay. It considered comparable cases and guidelines but found none perfectly analogous. The court assessed general damages for pain, suffering, and loss of amenity at €26,000 for the compensable period, reflecting the severity and duration of the Plaintiff’s illness caused by the delayed diagnosis.
Finally, the court granted reporting restrictions to protect the Plaintiff’s identity and medical condition, recognizing the constitutional imperative for open justice but balancing it against undue stress to the Plaintiff and the interests of justice.
Holding and Implications
The court found that The Hospital breached the standard of care by failing to specifically consider and diagnose visceral leishmaniasis (VL) by no later than 14 March 2014, approximately three weeks after the Plaintiff’s admission.
The failure to diagnose VL within this period led to unnecessary chemotherapy, prolonged hospitalisation, increased risk of infections, and avoidable suffering. The court awarded general damages of €26,000 for the pain and suffering attributable to this breach.
The court held that it was not negligent for The Hospital to fail to diagnose VL earlier than this period, given the rarity of VL in Ireland, the complexity of the clinical picture, and the reasonable working diagnosis of HLH triggered by HIV and HHV-8 initially pursued.
No new legal precedent was established; the court applied established principles regarding medical negligence, standard of care, and expert evidence evaluation. The decision underscores the importance of clinical judgment in complex cases involving rare conditions and the necessity to reconsider diagnoses when expected treatment responses fail to materialize.
