Physical restraints (PR) are widely used in ICU around the world. Many institutions have suggested that the use of PR should be reduced. Clinical practice guidelines (CPGs) are a convenient way of packaging evidence and presenting recommendations to healthcare decision makers. There are currently no CPGs on PR in China, while other countries had, so we hope to be able to adapt existing guidelines to apply in Chinese context. We use the CAN-IMPLEMENT approach to adapt and implement the guidelines.

Critically ill patients admitted to intensive care units (ICU) often need more invasive operations (e.g.mechanical ventilation and hemodialysis), due to the needs from their condition, which can also lead to acute pain, discomfort, sleep deprivation, agitation and delirium. Agitation, for example, can propel patients to resist the ventilator, thus increasing the oxygen consumption, causing them to accidentally remove various devices and catheters on them and even posing life-threatening risks. Therefore, the main reason for the use of physical restraints (PR) around ICU is to prevent patients from accidentally removing the catheters or devices needed to protect their safety.

Although PR was used to prevent Unplanned extubation (UE), there were many studies proved that PR is one of the risk factors that account for UE and can not protect patient safety. Indeed, its use has been proven to cause pressure injuries, worsen agitation, delirium and neurovascular complications. But PR is widely used in ICU around the world.

Many institutions have suggested that the use of PR should be reduced, for example, the Government of Ontario released the Patient Restraints Minimization Act in 2001 to "minimize the use of restraints on patients and to encourage hospitals and facilities to use alternative methods, whenever possible, when it is necessary to prevent serious bodily harm by a patient to himself or herself or to others. Registered Nurses Association of Ontario (RNAO) issued clinical practice guidelines on the alternatives to PR in February 2012, aimed to help nurses reduce the use of PR, or use it in a more reasonable and standardized way, and to provide effective alternatives of PR.

Clinical practice guidelines (CPGs) are a convenient way of packaging evidence and presenting recommendations to healthcare decision makers. But the development and updating of high-quality CPGs require substantial time, expertise and resources. Guideline adaptation is the systematic approach to the endorsement and/or modification of a guideline(s) produced in one cultural and organisational setting for application in a different context. Where high quality guidelines are already available, adaptation may be used as an alternative to de novo guideline development to customise the existing guideline to the needs of local users. There are currently no CPGs on PR in China, while other countries had, so we hope to be able to adapt existing guidelines to apply in Chinese context. We use the CAN-IMPLEMENT approach to adapt and implement the guidelines.
