The frontiers of medical negligence and diagnosis: an interview-based analysis

Abstract

While errors in medical diagnosis are common and often litigated, the different dimensions of diagnosis—formation, communication, recording—have received much less legal attention. When the process of diagnosis is differentiated in this way, new and contentious legal questions emerge that challenge the appropriateness of the Bolam/Bolitho standard. To explore these challenges, we interviewed 31 solicitors and barristers and asked them: (i) whether Montgomery should apply to information about alternative diagnoses; and (ii) whether the Bolam/Bolitho standard should be rejected in ‘pure diagnosis’ cases. Our qualitative analysis of the interviews sheds light not only on the two questions posed, but also on three cross-cutting themes. First, Bolam/Bolitho is criticised on two grounds that are often conflated: its paternalism for patients and its deference to medical professionals. Second, adopting different standards for different aspects of treatment and diagnosis may be justified in principle, but it can sometimes be difficult or not make sense in practice. Third, new conceptions of patients, doctors, and courts are being articulated in terms of rights or responsibilities over risks. In mapping these issues at the frontiers of medical negligence, this empirical study identifies potential pressure points for future legal developments.
