<p>Despite suspected suicidal hanging being a common referral to death investigation services there is variation and ongoing debate within the United Kingdom (UK) as to the extent of the postmortem investigations undertaken. This study aimed to gather opinions from Coroners/Procurator Fiscals and consultant autopsy pathologists within the UK on their views on the value of the key components of the traditional invasive autopsy in cases of suspected suicidal hanging. Online questionnaires were distributed to Coroners/Procurator Fiscals and consultant autopsy pathologists within the UK. The data was analysed using quantitative and reflexive thematic analysis. A total of 171 practitioners completed the questionnaire; 86 pathologists and 85 Coroners/Procurator Fiscals. Analysis revealed a wide range of opinion and practice concerning the role of each stage of the investigation in the decision making process. However, reflexive thematic analysis primarily identified that decisions on the approach to the investigation should be made on a case-by-case basis and the quality of each key component was imperative. Due to the variation in circumstances surrounding each case and the wide range of resources available to and approaches taken by death investigation services throughout the UK the study did not allow a firm recommendation to be made on the extent/limit of the examination required for the Coroner/Procurator Fiscal to conclude, on a balance of probabilities, that the death was due to suicidal hanging.</p>
