Project aims to reduce accidents and broken hips for older patients

Falls are one of the most common problems among elderly patients and are associated with fractures, reduced mobility and hospital admissions, and also lead to a loss of independence and confidence.(1) New data presented at the British Pharmaceutical Conference (BPC) in Manchester shows how a closer collaboration between pharmacy and physiotherapy may improve care for older people who fall.

Each year in Britain, a third of the population aged over 65 has a fall, and half of these people fall at least twice.(2)-(5) Multiple drug-taking among elderly patients is thought to increase the incidence of falls. An estimated four out of five people over 75 years take one or more prescribed drugs.(6).

The study carried out at Guy's and St Thomas' NHS Foundation Trust identified that many older patients who have fallen would benefit from having their medicines reviewed to identify any which may be contributing to them being unsteady on their feet and to ensure they receive the correct medicines to help with muscle and bone strength.

During the study, patients seen by physiotherapists after a fall or who were at risk of falling were automatically referred to the pharmacy team to assess whether or not they were taking drugs which may have contributed to their fall.

On the whole, prescribing was found to be appropriate. Although 87% were taking one or more drugs that can be associated with falls, these tended to be antihypertensives, diuretics and antidepressants, drugs where the clinical benefit is weighed against the risk of falling. Few patients were taking sedatives or hypnotics which are particularly problematic in falls patients.

However, the use of vitamin D and bone protection drugs was lower. Of people who had previously suffered a fracture, just over half received bone protection drugs and around 70% were prescribed vitamin D, which helps maintain muscle function.

Pharmacist Alice Oborne, who led the research, said: "Pharmacists and physiotherapists traditionally work independently but this is a novel approach to capturing patients who fall and would benefit from medication review. Sometimes, prescribing of drugs is a risk versus benefit decision and in this case, the clinical benefits of drugs must be weighed against whether they would significantly increase the patient's risk of falling.

"Pharmacists have a vital role to play in the relationship between drugs and falls prevention. Working closely with physiotherapy to offer patients a seamless service allows us to identify prescribing issues which might otherwise be missed and evidence-based multifactorial falls interventions like these can reduce patients' chances of falling again.''

This work was conducted in collaboration with the pharmacy department of Kings College London.
