Nurses are closely involved in their patient's current state of health and are often the first to witness (sometimes acute) changes in it. Good clinical judgement is therefore an essential professional skill. Three competences play a key role in clinical judgement: observing, analysing and communication. ProActive Nursing: Clinical Judgement helps nurses to make a professional assessment of 'how the patient is doing' and to clarify their patient’s clinical condition. ProActive Nursing: Clinical Judgement combines the eighteen health care topics of the World Health Organization's International Classification of Functions (ICF) with the three focal points of patient-centred care: wellbeing, bodily functions, and patient functioning. It clarifies what is going well and what is not, what the clinical problems, disorders and limitations of the patient are and what interaction there is between the different problems. All of the eighteen healthcare topics covered in this online book are summarized in a practical mind map showing the clinical focus points. There is also a section on the ‘Time-out practice model’ which helps nurses in a structured way how to apply their clinical judgement skills into practice.
