Patients across ten Derbyshire hospitals are now served only decaffeinated tea and coffee as a default, under a new policy introduced by the local NHS trust to reduce the risk of falls and other health complications.
Derbyshire Community Health Services NHS Foundation Trust, which operates community hospitals including Ilkeston and Ripley, implemented the change in January after reviewing clinical evidence on the effects of caffeine. The policy applies to Babington Hospital in Belper, Buxton Hospital, Cavendish Hospital, Clay Cross Hospital, St Oswald’s Hospital in Ashbourne, Walton Hospital in Chesterfield, Whitworth Hospital in Darley Dale, and Florence Nightingale Community Hospital in Derby.
Clinical rationale for the switch
The trust’s board papers describe caffeine as a central nervous system stimulant that has been clinically demonstrated to induce a range of adverse physiological responses. These include anxiety, sleep disturbances, cardiovascular reactions, and serious events such as arrhythmias. The trust identified direct links between caffeine intake and an increased risk of patient falls, disrupted sleep patterns, sudden spikes in blood pressure, and heart palpitations.
Board papers further noted that consuming more than two cups of coffee or four cups of tea daily may increase the likelihood of bone fractures.
The decision is backed by research conducted by Stow Healthcare, which showed a 34.72 per cent decrease in patient falls during trials where caffeine was not routinely offered. Incidents involving continence-related falls dropped by 30 per cent in the same study. The trust’s own analysis also highlighted improvements in sleep quality and fewer instances of sudden cardiovascular fluctuations after caffeine was removed.
Wider evidence from other NHS trusts
Similar initiatives elsewhere have produced comparable results. University Hospitals of Leicester NHS Trust ran a ‘Taste the Difference Challenge’ in 2021, making decaffeinated hot drinks the default option, which led to a 30 per cent reduction in falls related to toileting. Stow Healthcare, in partnership with Care England, conducted a trial in care homes that reported a 35 per cent reduction in toileting-related falls over six months. Northumbria Healthcare NHS Foundation Trust’s ‘Go decaf’ project also showed promising results, particularly in falls linked to toilet trips. Northampton General Hospital reported a 57 per cent drop in falls alongside improved sleep and reduced incontinence in elderly patients during a month-long trial.
How caffeine affects hospital patients
A significant driver behind these policies is the physiological impact of caffeine on vulnerable patients. Caffeine is a known diuretic and can irritate the bladder, increasing the urgency to use the toilet. This is particularly dangerous at night, when patients may be unsteady on their feet and at greater risk of falling. The trust’s board papers specifically mention that caffeine can induce sudden spikes in blood pressure and heart palpitations, which are especially concerning for patients already managing cardiovascular conditions.
The Mayo Clinic, a health research organisation, states that a typical cup of coffee contains approximately 96 milligrams of caffeine, while tea holds around 48 milligrams. Energy drinks contain about 79 milligrams, and a can of cola about 33 milligrams. The recommended safe daily intake for adults is up to 400 milligrams — roughly equivalent to four cups of brewed coffee or ten cans of cola. However, individuals who experience side effects such as headaches, nervousness, or sleep disturbances may need to consume less.
Consumer group Which? has previously found wide variation in caffeine content across high street coffee brands. A Starbucks cappuccino contained 66 milligrams, whereas an equivalent Costa beverage had 325 milligrams.
Beyond falls, reducing caffeine intake has been linked to improved skin health, calmer patients, reduced agitation, and potentially lower risk of bone fractures due to better calcium absorption. A report estimates that scaling up decaffeination initiatives across the care sector could save the NHS up to £85 million per year by preventing falls and related hospital admissions.
Exceptions and continued access
Despite the ward-level restrictions, patients and visitors can still obtain caffeinated drinks through other means. Vending machines dispensing both hot and cold caffeinated beverages remain operational at all trust hospital sites. Charitable community groups continue to operate cafes at the major Ilkeston and Ripley locations, with the trust’s endorsement, serving caffeinated drinks to patients, staff and visitors alike.
Patients may also request caffeinated beverages directly from ward staff if they wish. The trust maintains that individual choice is preserved, though the default offering is now decaffeinated. Some patients who switch may experience withdrawal symptoms — such as headaches and fatigue — typically starting 12 to 24 hours after cessation and lasting a few days. However, trials have shown that many patients report little difference in taste and are willing to make the change when informed of the benefits.
