Get better at managing multiple medicine use, warns report

Press release from the King's Fund.

Policy, medical training and clinical practice have failed to adapt to a significant increase in the number of patients taking multiple prescription drugs, according to a new report published by The King鈥檚 Fund and authored by an Honorary Clinical Senior Lecturer at 91精品黑料吃瓜.

Estimates suggest that from 1995 to 2010 the number of patients taking 10 or more medicines trebled (1), reflecting a large increase in the number of people with complex, or several, long-term conditions - largely driven by an ageing and increasingly frail population but also by increasing use of multiple interventions. While taking numerous prescription drugs (polypharmacy) has often been seen as something to be avoided in the past, the report shows that taking an evidence-based approach to polypharmacy should improve outcomes for many people.

However, with most research and health systems based on single disease frameworks, policy, medical training and clinical practice have often not adapted to provide 鈥榓ppropriate polypharmacy鈥� - optimising the use of multiple medicines and prescribing them according to best evidence.

The report in which Martin Duerden (2) was the lead author, with colleagues from other universities, suggests that for polypharmacy to be used more effectively there needs to be:

  • better training for doctors in managing complex multi-morbidity and in polypharmacy
  • more research set in the context of using treatments where people have several diseases, rather than selecting subjects who have single conditions
  • national guidelines for multi-morbidity to match those for single conditions
  • improved systems, particularly for GPs, to flag problematic polypharmacy
  • regular reviews of patients鈥� medication and a willingness to consider stopping medication, particularly in cases of limited life expectancy
  • changes in systems of medical care to move away from increased specialisation towards a focus on multi-morbidity

The report argues that polypharmacy needs to be better understood and defined, and accompanied by more engagement with patients to ensure that medicines are taken in the way that prescribers intend. This may require compromise between prescribers and patients to ensure that patients feel confident in what they are taking and situations where medicines go unused or are wasted are avoided.

Integrated care is now widely accepted as the way forward in caring for people living with multiple, complex, long-term conditions. Appropriate polypharmacy, or medicines optimisation, now needs to be similarly accepted as one of the ways in which we can deliver more coordinated care.

Martin Duerden, the report鈥檚 lead author, and clinical senior lecturer at  the University鈥檚 Institute for medical & Social Care Research said:

鈥淐urrently patients may still be treated in silos where one specialist doctor will look after their care for diabetes, another for their heart condition and a third for their asthma. They will then be prescribed medicines for each condition but these are often not considered in the whole. We need more generalist doctors able to understand a patient鈥檚 medicine in-take in its entirety and how they are managing, especially if they have to take numerous medicines at different times in the day.鈥�

He added:
鈥楢 sensible way forward might be to identify those taking 10 or more medicines and focus on them first. Their medicine intake should be regularly reviewed so that as well as adding a medicine as a condition worsens you can also scale back or even stop treatment 鈥� particularly recognising that end-of-life quality applies to chronic as well as cancer conditions.鈥�



1. Between 1995 and 2010 the proportion of people in a study of 300,000 patients in Scotland taking 10 or more drugs increased from 1.9 per cent to 5.8 per cent. This was a study by Guthrie and Makubate (2012). 

2. Martin Duerden has worked as a part-time GP in Conwy, North Wales since1999. In 2003 he became Medical Director at Conwy Local Health Board, reorganised to Betsi Cadwaladr University Health Board (BCUHB) in 2009. He now works as Deputy MedicalDirector for BCUHB, which covers all hospital and primary care services for North Wales a well as a Lecturer for 91精品黑料吃瓜.
