Updated medical guidance on “excited delirium” brought forward

Tide turning against controversial term accused of covering up deaths in police custody

2024-05-16
(Press-News.org) Updated medical guidance on excited delirium, the controversial term accused of covering up deaths in police custody, including that of George Floyd, is being brought forward before its scheduled date of October 2025, reports The BMJ today.

The move comes as attitudes towards the use of the term appear to be changing, explains journalist Chris Stokel-Walker. For instance, last month Colorado joined California in banning police, medical staff and coroners from using the term, and the UK Independent Office of Police Conduct (IOPC) removed the phrase from its incident forms.

The phrase “excited delirium” was first coined by two doctors working in Miami in the 1980s, but subsequent analyses have never found a reliable medical basis for its use in the medical lexicon.

Yet it and a related term more common in the UK, “acute behavioural disturbance” (ABD), have been mentioned as a cause of death or contributing factor in 44 cases of UK police restraint since 2005, according to an investigation published in March 2024 by the charity Inquest, the Royal College of Psychiatrists and the Observer. 

An earlier study published in July 2023 found that mentions of ABD in mental health records in one London NHS trust increased year-on-year between 2006 and 2021.

James MacCabe, professor of epidemiology and therapeutics at King’s College London, believes that the use of both terms is misguided, while Catherine Polling, NIHR clinical lecturer in general psychiatry, also at King’s College London, says: “It’s not traditionally a term that we use, and it’s not in any of our diagnostic manuals.”

The guidance, produced by the Faculty of Forensic & Legal Medicine (FFLM), part of the Royal College of Physicians, is used to inform police forces’ handling of suspects in custody. 

In 2019, the guidance linked excited delirium and ABD together, discussing how the two overlapped with one another. But an updated version in 2022 shied away from using excited delirium and included additional warnings about using specific forms of restraint and medicine that could result in harm or death to those it was being enacted upon. 

Controversy over the terms are well-warranted, argues MacCabe. “In the case of George Floyd, it’s quite clear what is happening: it’s being used as a way of explaining the fact that people have died when they’ve been in police custody or when they’ve been restrained, and it’s a way of deflecting attention away from the restraint techniques that might have been used.” 

There is also another reason why it’s such a controversial diagnosis, says MacCabe: it seems to be predominantly applied to black people.

The same July 2023 analysis that tracked ABD mentions in the London NHS trust found that black people were more than twice as likely to have ABD referenced in mental health assessments than white people, while a US analysis of 166 reported deaths in police custody between 2010 and 2020 attributed to excited delirium found that black people were 43.3% of the reported deaths. 

A separate study shows that excited delirium is mostly cited as a cause of death in people who have previously been restrained. 

The IOPC said in a statement: “We have decided to stop using the term ‘excited delirium’ as we recognise that it is language that is outdated and potentially offensive. We have removed it from IOPC forms that police forces use to make referrals to us and will not use the term as an option for categorising our investigations.” 

While unable to share a draft of the new FFLM guidance, Margaret Stark, one of the authors, can confirm that it updates references to include the latest knowledge, and removes references to non-clinical terms such as “disproportionate superhuman strength.”

Stark is happy to see the back of excited delirium but thinks losing the term ‘acute behavioural disturbance’ would be a mistake. She points to the importance of having a label for when people feel severe anxiety in police custody, because feeling that anxiety can lead to changes in the body that become a medical emergency. 

Experts agree it’s time to find a better term, but what should replace excited delirium?

Andrew Stolbach, associate professor of emergency medicine at Johns Hopkins University, says that not having a way to define the issues he encounters with patients does them a disservice, though he dislikes “excited delirium.” He says he’d prefer to describe the symptoms in front of him, rather than assume a diagnosis without further tests.

He believes it also serves another, more noble, purpose. “Whenever there’s a term that's historically been associated with racism, it’s important to be sensitive to that,” he says. “We need to recognise the weight that that carries. And that’s just even more reason to move on.”

New study shows continued high effectiveness of HPV vaccination in England

2024-05-16
The human papillomavirus (HPV) vaccination programme in England has not only been associated with a substantial reduction in cervical disease, but has done so in all socioeconomic groups, finds a study published by The BMJ today. Although women living in the most deprived areas are still at higher risk of cervical disease than those in less deprived areas, the results show that well planned and executed public health interventions can both improve health and reduce health inequalities.

Carbon-capture batteries developed to store renewable energy, help climate

Carbon-capture batteries developed to store renewable energy, help climate
2024-05-15
Researchers at the Department of Energy’s Oak Ridge National Laboratory are developing battery technologies to fight climate change in two ways, by expanding the use of renewable energy and capturing airborne carbon dioxide.  This type of battery stores the renewable energy generated by solar panels or wind turbines. Utilizing this energy when wind and sunlight are unavailable requires an electrochemical reaction that, in ORNL’s new battery formulation, captures carbon dioxide from industrial emissions and converts it to value-added products.   ORNL researchers recently created and tested two different formulations for batteries that ...

From roots to resilience: investigating the vital role of microbes in coastal plant health

From roots to resilience: investigating the vital role of microbes in coastal plant health
2024-05-15
Georgia’s saltwater marshes — living where the land meets the ocean — stretch along the state’s entire 100-mile coastline. These rich ecosystems are largely dominated by just one plant: grass. Known as cordgrass, the plant is an ecosystem engineer, providing habitats for wildlife, naturally cleaning water as it moves from inland to the sea, and holding the shoreline together so it doesn’t collapse. Cordgrass even protects human communities from tidal surges. Understanding how these ...

Q&A: How did the COVID-19 pandemic affect older adults’ technology use?

2024-05-15
The onset of the COVID-19 pandemic changed how nearly everyone mediated their social interactions through technology. Some moved happy hours into video chats. Others delved deeper into social media, or took a step back from it. Millions of people worked or learned through computers. University of Washington researchers took particular interest in how this tech shift affected older adults’ social relationships. The team interviewed 16 older adults in Washington and Oregon, ages 65 to 80, about how their technology ...

Blood pressure drugs more than double bone-fracture risk in nursing home patients

2024-05-15
Records from nearly 30,000 nursing home residents indicate that blood pressure medications more than double the risk of life-threatening bone fractures, according to Rutgers Health research. The authors of the study, which appears in JAMA Internal Medicine, said the increased risk stems from the medications’ tendency to impair balance, particularly when patients first stand up and temporarily experience low blood pressure that deprives the brain of oxygen. Interactions with other drugs and low baseline balance in many nursing home patients compound the problem. “Bone fractures often start nursing home patients on a downward spiral,”  ...
