Patient safety is a fundamental principle of health care. Every point in the process of care-giving contains a certain degree of inherent unsafety. A number of countries have published studies showing that significant numbers of patients are harmed during health care, either resulting in permanent injury, increased length of stay in health care facilities, or even death.
Adverse events may result from problems in practice, products, procedures or systems. A combination of numerous unfavourable factors such as understaffing, inadequate structures and overcrowding, lack of health care commodities and shortage of basic equipment, and poor hygiene and sanitation, contribute to unsafe patient care. A weak safety and quality culture, flawed processes of care, and disinterested leadership teams further weaken the ability of health care systems and organizations to ensure provision of safe health care.
