Have you washed your hands - another study on patient safety

Since the report by the Institute of Medicine in 2000 that found high rates of medical mistakes in the US, most US hospitals had made efforts to improve patient safety. A new study, published in the NEJM found that patient harm in hospitals has not decreased over time!

Harvard researchers reviewed 2341 admission records obtained from 10 randomly selected hospitals in North Carolina between 2002 and 2007, they found 588 incidents of patient harm, ie 25.1 harms per 100 admissions, resulting from medical procedures, medications, or other causes.
The study found that infections was one of the most common complications, 42.7% required longer hospital stay for treatment, eg infected surgical incision. The types of patient harm varied widely and included falls, injury during surgery, low blood pressure and low blood sugar. Most of the complications were temporary and treatable, but 3% were permanent, eg brain damage from a stroke ( could have been prevented after an operation), 8.5% were life-threatening and 2.4% "caused or contributed to a patient's death."

The study's lead author, Dr. Christopher Landrigan, said "these harms are still very common, and there's no evidence that they're improving". Many of the problems were caused by the hospitals' failure to use protective measures that have been proven to improve care including computerizing patient records and drug prescription orders, using checklists for surgical procedures and other methods. He noted that the frequency of medical errors and injuries has been underestimated and there is a need for a mandatory monitoring system.

Some experts on hospital safety said heathcare providers should have a culture of strong communication and teamwork and it is essential that hospitals be more open about reporting problems. Some suggest that patients need cultural change too in ensuring their own safety, eg discussing about drug interactions with the doctor or asking if the doctor has washed his/her hands!

In the US, 27 state laws require public reporting of hospital-acquired infection rates. In 2005, all hospitals in New York were required by legislation to report hospital-acquired infections to the NY State Department of Health. In 2009, the NY Department of Health issued a state-wide report on hospital-by-hospital infection rates. They said that the information will help patients make more informed choices and allow hospitals to compare with other providers.

In the UK, despite promoting hand hygiene among staff, patients and visitors in NHS Trusts in England and Wales to reduce hospital acquired infections, infection rates and resulting harm are still very high.

In June 2010, the Health Secretary, Andrew Lansley, announced that as part of the new government's information revolution, infection figures for all hospitals in England will be published on a weekly basis from July on the government website . By making the data available to patients as well as hospital managers, he said people can make comparisons between different hospitals and healthcare organisations.

Have you washed your hands? Would you be offended if a patient or a colleague asks if you have washed your hands? What's your veiw?
