There to care; not to kill: medical settings, statistics and wrongful convictions

2026-05-08

AI Summary

This study addresses the wrongful convictions of nurses in healthcare settings based on anomalous mortality statistics, exposing a systemic bias in judicial practice that conflates statistical correlation with causal evidence while disregarding direct forensic findings and eyewitness testimony. Employing an interdisciplinary approach—integrating forensic evidence review, statistical data analysis, and semantic interpretation of case files and personal diaries—the research offers the first systematic critique of the flawed logic underpinning such convictions and examines how institutional power dynamics within medical hierarchies shape investigative priorities. The analysis identifies recurring patterns of evidentiary weakness across multiple miscarriages of justice, thereby advocating for a reformation and standardization of how statistical evidence is evaluated and applied in criminal cases involving healthcare professionals.

Abstract

This paper discusses wrongful convictions in a medical setting, focusing on nurses. Common features are lack of strong direct evidence: the nurse was never seen doing anything wrong. There is no DNA evidence of tampering of apparatus or medications by the nurse. There is no CCTV footage showing suspicious actions. Analysis of medical records at the time led coroners to issue certificates of natural deaths, and most events were not, at the time, thought suspicious by hospital staff. There is no confession and the nurse consistently asserts they are completely innocent. There is no evidence of earlier psychopathic behaviour. Instead, private writings (e.g., in a diary) are interpreted by the prosecution as a confession; mundane behaviour is given a sinister interpretation. Motive remains speculation. The main evidence is statistical: a spike in deaths or collapses and a statistical association with a particular nurse. There is forensic evidence which suggests one or two patients might have been harmed by administration of medication much used in the hospital, and even legitimately used earlier in the care of the alleged victims. Police investigations are driven by the hospital consultants who were clinically responsible for the patients allegedly killed or harmed by the nurse.
