Holding

The High Court held that TASO Uganda Limited was negligent in diagnosing the Plaintiff as HIV positive without following WHO testing guidelines, issuing an erroneous positive result based on inconclusive test data, and dispensing antiretroviral medication for seven years without proper verification or reassessment despite the Plaintiff's reported adverse reactions and subsequent negative independent test results. The Court awarded general damages of UGX 140,000,000 and aggravated damages of UGX 50,000,000.

Outcome

Judgment entered for the Plaintiff with declarations of negligence, damages totaling UGX 190,000,000, interest at 10% per annum, and costs

Facts

In July 2016, the Plaintiff voluntarily attended TASO Jinja for HIV testing. He was informed he was HIV positive and placed on antiretroviral therapy. The Defendant's testing register showed an altered first-test result (Determine marked Non-Reactive without countersignature) and no quality control performed on test kits that day. The serial testing algorithm yielded inconclusive results (Determine+; Stat Pak-; Uni-Gold+) but the Plaintiff was not retested after 14 days as required by WHO guidelines. He took ARVs continuously for approximately seven years, experiencing persistent adverse reactions including excessive sleep, dizziness, and weakness that impaired his work capacity. In 2022, when applying for NSSF benefits, independent PCR tests returned HIV negative results. The Defendant retested the Plaintiff in 2023 and confirmed negative status. The Plaintiff claims the misdiagnosis destroyed his marriage, employment, and social standing, causing grave psychological harm.

Issues

  1. Whether the Defendant was negligent in carrying out the HIV test and care.

Rules and key headnotes

Medical Negligence — Duty of Care Owed by Specialist HIV Treatment Institution
A specialist HIV treatment institution owes a particularly high duty of care to patients entrusting their lives to its diagnosis; the gravity of HIV diagnosis and its lifelong consequences demands that those holding themselves out as possessing special skill must exercise that skill with reasonable competence.
Medical Negligence — Compliance with Protocol Not Substitute for Professional Judgment
Compliance with written medical protocol is relevant but not determinative of reasonable professional care; professional practice must itself be capable of logical justification, and a court is entitled to examine whether practice relied upon meets the standard of reasonableness, particularly where the protocol itself is applied incorrectly or illogically.
Medical Negligence — HIV Testing Standards — WHO Consolidated Guidelines
Where serial HIV testing yields inconclusive results (first assay reactive, second assay non-reactive, third assay reactive), WHO Consolidated Guidelines on HIV Testing Services (2015) require the status to be reported as HIV-inconclusive with retesting after 14 days; using the third assay as a tiebreaker to issue a positive diagnosis over-selects for false positives and constitutes negligence.
Medical Negligence — Quality Control and Record Integrity
Failure to perform quality control on HIV test kits on the material day of testing and alteration of testing register entries without countersignature constitute breaches of essential laboratory practice; external quality assurance audits conducted months later cannot retrospectively validate procedures that on the material day departed from required standards.
Medical Negligence — Continuing Duty to Reassess Diagnosis
A hospital owes a continuing duty to ensure treatment remains appropriate to the patient's actual condition; where a patient reports persistent serious adverse reactions and functional decline, reasonable care requires periodic reassessment of the foundational diagnosis, and blind adherence to a policy against retesting cannot absolve a clinician from the obligation to treat the patient before them.
Burden of Proof — Adverse Inferences Against Custodian of Records
Where a plaintiff demonstrates discordant test results and produces the defendant's own records evidencing adverse effects, an evidential burden shifts to the defendant medical institution, as custodian of the laboratory system and best placed to explain safeguards undertaken; failure to provide such explanation permits an adverse inference under section 147 of the Evidence Act.
HIV Testing — Statutory Mandatory Referral for Discordant Results
Under section 48 of the HIV and AIDS Prevention and Control Act, where a person tests HIV positive initially and later tests negative, the health unit shall forward a sample to the Ministry of Health Laboratory for authoritative confirmation; non-compliance with this mandatory duty constitutes breach of statutory duty rendering the health institution liable for civil wrong.
