According to WHO Report, globally, the cost associated with medication errors has been estimated at US$ 42 billion annually or almost 1% of total global health expenditure.
WHO today launched a global initiative to reduce severe, avoidable medication-associated harm in all countries by 50% over the next 5 years.
“We all expect to be helped, not harmed, when we take medication,” said Dr Margaret Chan, WHO Director-General. “Apart from the human cost, medication errors place an enormous and unnecessary strain on health budgets. Preventing errors saves money and saves lives.”
Every person around the world will at some point in their life take medicines to prevent or treat illness. However, medicines do sometimes cause serious harm if taken incorrectly, monitored insufficiently or as the result of an error, accident or communication problems.
The Global Patient Safety Challenge on Medication Safety aims to address the weaknesses in health systems that lead to medication errors and the severe harm that results. It lays out ways to improve the way medicines are prescribed, distributed and consumed, and increase awareness among patients about the risks associated with the improper use of medication.
Medication errors cause at least one death every day and injure approximately 1.3 million people annually in the United States of America alone. While low- and middle-income countries are estimated to have similar rates of medication-related adverse events to high-income countries, the impact is about twice as much in terms of the number of years of healthy life lost. Many countries lack good data, which will be gathered as part of the initiative.
“Over the years, I have spoken to many people who have lost loved ones to medication-related errors,” said Sir Liam Donaldson, WHO Envoy for Patient Safety. “Their stories, their quiet dignity and their acceptance of situations that should never have arisen have moved me deeply. It is to the memories of all those who have died due to incidents of unsafe care that this Challenge should be dedicated.”
Both health workers and patients can make mistakes that result in severe harm, such as ordering, prescribing, dispensing, preparing, administering or consuming the wrong medication or the wrong dose at the wrong time. But all medication errors are potentially avoidable. Preventing errors and the harm that results requires putting systems and procedures in place to ensure the right patient receives the right medication at the right dose via the right route at the right time.
Medication errors can be caused by health worker fatigue, overcrowding, staff shortages, poor training and the wrong information being given to patients, among other reasons. Any one of these, or a combination, can affect the prescribing, dispensing, consumption, and monitoring of medications, which can result in severe harm, disability and even death.
This challenge is WHO’s third global patient safety challenge, following the Clean Care is Safe Care challenge on hand hygiene in 2005 and the Safe Surgery Saves Lives challenge in 2008.
