Abstract
Patient harm due to unsafe healthcare is widespread, potentially devastating, and often preventable. Hoping to eliminate avoidable harms, the World Health Organization (WHO) published the Global Patient Safety Action Plan in July 2021. The UK's National Health Service relies on several measures, including ‘never events’, ‘serious incidents’, ‘patient safety events’ and coroners’ Prevention of Future Deaths reports (PFDs) to monitor healthcare quality and safety. We conducted a systematic narrative review of PubMed and medRxiv on 19 February 2023 to explore the strengths and limitations of coroners’ PFDs and whether they could be a safety tool to help meet the WHO's Global Patient Safety Action Plan. We identified 17 studies that investigated a range of PFDs, including preventable deaths involving medicines and an assessment during the COVID-19 pandemic. We found that PFDs offered important information that could support hospitals to improve patient safety and prevent deaths. However, inconsistent reporting, low response rates to PFDs, and difficulty in accessing, analysing and monitoring PFDs limited their use and adoption as a patient safety tool for hospitals. To fulfil the potential of PFDs, a national system is required that develops guidelines, sanctions failed responses and embeds technology to encourage the prevention of future deaths.
Introduction
Patient harm due to unsafe care is a growing global public health challenge that demands an urgent international response. In July 2021, the World Health Organization (WHO) published the Global Patient Safety Action Plan, with the intention of eliminating avoidable harms in healthcare. 1 In the UK, the National Health Service (NHS) has several initiatives and measures in place to monitor and improve patient safety, including ‘never events’, ‘serious incidents’, coroners’ Prevention of Future Deaths reports (PFDs), and patient safety events (i.e. ‘harms’) reported by patients, the public, and staff. 2 However, it has been estimated that over 10,000 adult deaths in English hospitals are preventable each year. 3
Death is the most severe and objective marker of harm, making it the most used primary outcome in research and healthcare settings worldwide. However, not all deaths are inevitable. Treatment and prevention are two mechanisms by which avoidable deaths can be averted. According to the Office for National Statistics (ONS), preventable mortality describes a death that can be avoided ‘before onset of disease or injury… through effective public health and primary interventions’, 4 and treatable mortality is death that can be avoided ‘after onset of a disease… through timely and effective healthcare interventions’ to reduce case-fatality. 4
Patient safety data
Each year in the NHS, 32,000 records of so-called patient safety events (i.e. harms) are reviewed. 2 The NHS estimates that 160 lives and £13.5 million in treatment costs are saved every year because of the incident review and response efforts of the NHS Patient Safety Strategy. 5 Records are provided from established sources, including Serious Incident reports, Never Events, events that are recorded on the National Reporting and Learning System (NRLS), and coroners’ PFD reports. 2 NHS England and affiliated organisations publish summaries and reports of Never Events at regular intervals.6,7 Furthermore, patient safety incident reports (i.e. reports of harms) are stored in the NRLS database, with organisational and national summaries published by NHS England and NHS Improvement. 8 A systematic search of the literature showed that most published research on harms refers to ‘never events’ (Figure 1, Table S1), and PFDs were an underexploited resource. To explore the potential of PFDs, we conducted a systematic narrative review of studies that investigated PFDs.

Bibliometric analysis of patient safety events (i.e. harms) as indexed in PubMed from their dates of introduction (arrows) to 16 November 2022, including the National Reporting and Learning System (NRLS; black), which was introduced in 2003 (black arrow), Never Events (grey), which were introduced in 2009 (grey arrow), and Serious Incident reports (dotted), which were introduced in 2010 (dotted arrow). 12 The search strategy is summarised in Supplement Table S1.
What are PFDs?
Coroners issue Prevention of Future Death reports (PFDs) when they consider it appropriate to share information detailing actions to be taken to prevent further deaths. PFDs are mandated under The Coroners and Justice Act 2009 9 and The Coroners (Investigation) Regulations 2013. 10 Three processes are involved in issuing PFDs (Figure 2). Once a PFD is written, it is uploaded to the Courts and Tribunal Judiciary website, 11 and assigned to a ‘category’ or multiple categories of deaths.

The Prevention of Future Deaths reports (PFD) process in the context of all deaths in England and Wales, adapted from Zhang and Richards (2022). 13 When an unnatural or unclear death occurs, it may be reported to a coroner. Further investigations, including a post-mortem and inquest, may be requested by the coroner to explore the circumstances and causes of death. After the inquest, if the coroner deems that the death could have been prevented, it is their duty to write a PFD and send it to individuals and/or organisations capable of actions. 10 Recipients of PFDs must respond within 56 days under the statute. 10 PFDs and their responses may be published on the Courts and Tribunal Judiciary website. 11 The percentage of deaths proceeding through each stage was reported in the Chief Coroner's Annual report for 2019. 14
Methods
We conducted a systematic narrative review to identify literature relating to PFDs. We searched PubMed and medRxiv on 19 February 2023 and conducted forward (citations) and backward (reference lists) screening of included studies. Search terms and the search strategy are available in Supplement Tables S2 and S3. For medRxiv, the first two pages of the database were screened to identify unpublished literature.
Studies were screened independently by one reviewer (BTB), cross-checked by a second reviewer (GCR), and shared with a clinical pharmacologist (JKA) who is an expert in the field, for final validation of the list of eligible studies. Studies were included if they reported the use of PFDs as a source of data and/or discussed the strengths and limitations of PFDs in practice and were published in English and related to the English and Welsh coronial and healthcare system regardless of study design. Research letters, commentaries, and editorials were excluded.
Data were extracted and synthesised by one reviewer (BTB) and cross-checked by a second reviewer (GCR). Data relating to the types of PFDs, reported outcomes, and strengths and limitations of PFDs as reported by included study authors, were extracted and summarised narratively. We used content analysis to assess the frequency and patterns of reported strengths and limitations. No meta-analysis and/or quality assessment was performed. Graphs were created with matplotlib.pyplot and numpy packages in Python using Spyder, and flow diagrams were created using Microsoft PowerPoint.
This review was not preregistered, and no review protocol was prepared, owing to the narrative nature and study design. The findings were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist where applicable.
Results
After screening and removing duplicates, 17 studies13,15–30 that examined PFDs in England and Wales were included (Figure 3).

The search strategy used for PubMed and medRxiv databases is available in Supplement Tables S2 and S3. *For medRxiv, the first two pages (20 results) were screened to identify unpublished literature.
Eight studies (47%) explored PFDs describing medicines and drugs that had caused or contributed to deaths,15,16,19,24–26,29,30 two studies assessed PFDs involving chemical products, including paraffin-based emollient creams and alcohol-based hand sanitisers,21,28 one study examined PFDs involving diagnostic errors, 27 four publications explored healthcare-related PFDs,17,18,20,22 and two studies analysed PFDs using a selection of categories from the Courts and Tribunals Judiciary website13,23 (Table 1). Across these studies, preventable deaths often occurred in hospitals. An analysis of all available PFDs between July 2013 and June 2022 (n = 4001) showed that hospital-related deaths were the most common category (44%; n = 1772 PFDs) reported on the Courts and Tribunals Judiciary website. 13 We therefore focused on the strengths and limitations of PFDs as a tool for assessing patient safety in hospitals.

Strengths of PFDs
Studies investigating PFDs have highlighted that they contain rich information and provide essential lessons. Thirteen studies13,15,16,18–26,29 illustrated the potential of PFDs to drive improvements in hospitals and prevent deaths if coroners’ concerns were addressed (Supplement Table S4). For example, lives lost in hospital tragedies, such as the Gosport scandal, 31 could have been prevented if concerns documented in PFDs had been widely disseminated to ensure that actions were taken nationally to safeguard patients.
PFDs have influenced organisations to act, as reported in several studies.18,24,25,28,29 For example, concerns expressed in PFDs led the Medicines and Healthcare products Regulatory Agency (MHRA) to issue a ‘Drug Safety Update’ Bulletin and give wider publicity to fatal adverse drug reactions. 24 However, research to date has focused on analysing coroners’ concerns in PFDs rather than the actions reported or proposed in responses to PFDs by recipients. Thus, the full potential of PFDs to detect unsafe care and promote change in hospitals is currently underexplored.
Limitations of PFDs
Several problems in writing PFDs, responding to them, and the ways in which they are written and collected have been highlighted, including inconsistent reporting, poor response rates, and difficulties in accessing and analysing them. Coroners’ practices vary and are not monitored or audited. Three studies13,23,24 showed significant variability in the rate at which individual coroners produce PFDs, and six studies13,15,20,22,23,29 have reported geographical variation (Supplement Table S4).
The criteria that lead a coroner to write a PFD after an unnatural death, and how coroners decide what information will be included or excluded, are unclear. Two studies18,22 showed considerable differences in the quality, detail, length, and structure of reports. Missing information and errors were frequently identified, including failure to disclose the date of birth or age at death, the names or classes of medicines implicated,15,16,20,22,29 misspelled names, and incorrect dates,13,22 all of which impair the usefulness of PFDs. In a survey of 32 coroners in 2010 to 2011, in which they were asked to state and describe their purpose, only six mentioned the importance of preventing deaths as part of their purposes, and only four specifically mentioned PFDs as a tool for doing so. 32 Nevertheless, the attitudes of coroners towards PFDs have improved in the last decade. In the 2020 Coroner Attitude Survey, 96% of coroners responding felt that one of the most important functions of coroners was to ‘prevent future deaths’. 33 More than half of coroners (55%) also felt that PFDs were effective in preventing future deaths. 33
Given that 16% of all deaths (n = 104,940) were considered preventable in Great Britain in 2020 4 and that only 0.1% resulted in a PFD report, 14 PFDs cannot represent all the actions required to prevent deaths. Cooper et al. highlighted that PFDs report the most severe cases of harm and therefore may not offer generalisable lessons. 27 There is also the problem of timeliness, limiting how swiftly actions can be implemented, owing to the constraints of the coronial system; Ferner et al. 25 found a median delay of 240 days from the date of death to the issue of a PFD. Despite the lag, the concerns in these PFDs still warrant wide public dissemination, to ensure that actions are accountably implemented.
PFDs are unlikely to be highly effective if they are not widely circulated. Responses to PFDs showcase actions taken or proposed that could be implemented nationally or globally to prevent future deaths. However, three studies24,25,29 showed that PFDs, which would have benefitted from national dissemination, were most often sent only to local organisations. Despite the statutory requirement for recipients to respond to PFDs within 56 days, 10 studies reported varyingly low timely response rates between 29% and 37%.15,16,29 There are no sanctions, penalties, or public accountability for failure to respond to PFDs 23 and whether actions reported in responses are implemented is unknown.13,15,16,20–22,29 There is also no mechanism for retaining knowledge and lessons from implementing actions taken after PFDs have been issued. This suggests that there is a need for a two-stage response system where the actions are proposed first in detail then a second response is required sharing how those actions were taken and their results. However, most PFD research has focused on analysing concerns in PFDs rather than the information in responses. Therefore, future research should investigate actions reported or proposed in responses to PFDs.
The impact of PFDs is yet to be fully elucidated, as studies of their effectiveness in improving clinical practice and policy have not been conducted. Several authors15,16,18,22,24,26,29 have reported that coroners raised repeated concerns, suggesting that PFDs did not result in the implementation of remedial actions. For example, a case report of two deaths from alcohol-based hand sanitisers illustrates that if lessons had been disseminated nationally and actions had been implemented in all hospitals, such as the use of lockable dispensers, after the first death in 2013, a subsequent death, in 2015, might have been prevented. 21 In some cases, the issues that led to death (e.g. purchasing drugs from the dark web or online pharmacies) are complex 30 and thus require multifaceted solutions. Before PFDs can be fully incorporated as a patient safety tool for hospitals, future research should assess the effectiveness of PFDs to improve practice and safety and reduce the occurrence of preventable deaths.
The current mechanism of disseminating PFDs on the Courts and Tribunals website is inadequate. To access and analyse information in PFDs requires many hours (and years) of manual labour. Four studies13,15,16,24 showed that PFDs were poorly or incorrectly categorised on the Courts and Tribunals website, with 73% of PFDs (n=2939) not assigned to any category, 13 creating ambiguities and impairing the ability to compare PFDs with national data (e.g. from the Office of National Statistics) and international data, which use internationally recognised classification systems to report deaths (e.g. the WHO International Classification of Diseases 11th Revision (ICD-11)). After more than five years of using and scraping the Courts and Tribunals website, several issues have emerged, including significant missing information, misspellings, and formatting inconsistencies. 13 Our web scraper and the Preventable Deaths Tracker (https://preventabledeathstracker.net/), which collates PFDs and receives more than 10,000 users each month, 34 are helping to streamline analysis and remove some of these problems, to make PFDs more accessible. However, the Chief Coroner's Office should continue to introduce technologies and systems to improve the dissemination and use of PFDs.
Discussion
In this narrative review, we identified 17 studies13,15–30 that analysed PFDs in England and Wales. PFDs documenting deaths related to medicines and drugs were explored most (47%; n = 8), followed by deaths involving healthcare (24%; n = 4) and chemical products (12%; n = 2). Currently, the strengths of PFDs lie in the great depth and high quality of information PFDs provide on individual deaths and the clear potential of PFDs to prevent future deaths if well implemented. PFDs, however, are currently limited by inconsistent quality and rates of reporting, poor response rates, and challenges in accessing and analysing them.
The Australian and New Zealand National Coronial Information System (NCIS), established in Australia and New Zealand in 2001 and 2007, respectively, has contributed cases to over 200 publications cited in PubMed, nearly 70% of which involved medicines. 35 This displays the potential for PFDs in the UK and should encourage the adoption of similar systems in other countries.
Terminology
The term ‘safety’ is often used in relation to adverse drug effects and reactions, but in this review, we refer to harms, since pharmacovigilance is primarily concerned with seeking evidence of harms, not safety. In clinical practice, it is ‘patient safety’ that is being sought, that is, the avoidance of harms. Elsewhere, we have used ‘patient safety’ as ‘avoidance, prevention, or mitigation of the hazards posed by therapeutic interventions (drugs, devices or procedures) or the harms that arise from their use’. 36 Thus, a ‘patient safety tool’ is any piece of information that can be used and implemented to increase the chance of patient safety.
Strengths and limitations
Our review is limited by the included research. Only two databases, PubMed and medRxiv, were used for screening, although forward and backward screening was performed to improve our search strategy. Included studies explored many important types of PFDs, such as those involving medicines and COVID-19. However, many causes and settings of preventable deaths, such as hospitals, remain unexplored. As a result, our findings reflect only the PFDs so far investigated, and it is unknown where these strengths and limitations extend to all PFDs.
Furthermore, while poor rates of response have been identified, research into responses and the actions they report or propose to PFDs is limited. It is therefore difficult to assess the quality of responses to PFDs and the corresponding effectiveness of PFDs. The current barriers and facilitators to writing and responding to PFDs remain under-researched, preventing the development of potential strategies to improve the PFD system.
Implications
PFDs could play a crucial role in measuring and improving patient safety and in supporting the goals of the WHO's Global Patient Safety Action Plan to minimise harms in healthcare. The information in PFDs is the highest quality of evidence available for preventing such deaths, as other study designs, such as clinical trials, are neither feasible nor ethical to perform in such circumstances. Despite the limited quantity of PFDs (0.1% of all deaths), 14 they offer unparalleled insights into deaths due to patient safety errors in hospitals, by providing details not offered by other safety data, such as Serious Incident reports, Never Events, and events recorded on the NRLS. PFDs offer important opportunities for shared information to improve patient safety and could ultimately help prevent future deaths.
Despite the clear role PFDs could play in informing practice, immediate actions are needed to facilitate writing them, to encourage responses to them, and to enhance the ways in which they are reported and implemented.
National guidelines for PFDs should be introduced to address variability in reports and the use of sanctions, penalties, and/or public accountability should be considered to increase response rates. Given that only one PFD was written for every 328 preventable deaths estimated in 2020 (0.29%; 302 PFDs vs. 104,930 preventable deaths4,11), the introduction of an inclusive system that requires coroners to report, after every inquest, the actions taken or proposed, would increase the learning from preventable deaths.
In the meantime, technology should be embedded into the PFD system to improve data quality, collection, automation, and timeliness of PFDs. A regular bulletin and analysis of PFDs should be sent to hospitals and general practitioners to increase their use and lessons learnt. Investment in research is needed to examine the facilitators and barriers to writing and responding to PFDs, the effectiveness of PFDs, actions reported or proposed in responses to PFDs and geographical variations. Using PFDs, many important and wide-reaching types of death, such as those involving medicines and chemical products, have been examined. However, analysis of PFDs and responses detailing deaths in hospitals is an important evidence gap that requires further research.
Conclusions
Preventable deaths are a measure of avoidable harms due to unsafe care. However, current patient safety metrics fail to facilitate the implantation of actions to prevent future deaths, particularly in hospitals. Coroners write PFDs to describe concerns from deaths that should be acted upon to avoid further harms. Academic research has recently begun to unlock a wealth of information on patient safety concerns and to identify some of the ways in which PFDs can contribute. While PFDs may have a limited impact on patient safety in hospitals in their current form, a collective effort involving the Chief Coroner's Office, coroners, policy makers, bereaved families, healthcare professionals, researchers, the media, and the public could restructure and improve the PFD system to unleash their potential. Improved guidance, enforcement of Regulations 29 of The Coroners (Investigations) Regulations 2013, investment in infrastructure and research, and integration into the NHS Patient Safety Strategy are essential for improving PFDs. PFDs offer a unique opportunity to help fulfil the responsibility of hospitals in preventing deaths and ensuring patient safety.
