The book is adapted to a necessary level of infection prevention to cope with today’s emerging and resistant microbes, hygienic challenges and emer- gency preparedness in practical work. It updates current knowledge about infection protection as basic for selecting routines and guidelines to prevent hospital infections. Healthcare-associated infection (HAI) is primarily a patient safety issue, causing more than 90% of patient injuries. Leaders at all levels in the healthcare system are responsible for patient safety and infection control, from the director of the hospital to the health minister and government, and this should be warranted by law. Lack of management is associated with overcrowding, understaffing, corridor-beds, poor maintenance of buildings and equipment, inadequate cleaning and basic hygienic measures which often lead to HAIs. Hospital infections may occur in 5–20% or more of hospitalized patients. In Europe, at least 7.5 million patients acquire HAI each year, and more than 147,000 patients die directly or indirectly from HAIs each year in European hospitals. Hospital infections are detected more often after discharge, due to shorter and shorter stay in hospitals. This may lead to spread of resistant bacteria between healthcare levels and less favourable outcome for the patient with infection. Virus like influenza and norovirus follow the patient and may spread like “fire in dry grass”. Entire departments with patients and personnel will be “sick-reported” and must shut down all activity for 2–3 weeks. The spread of resistant and/or particularly pathogenic, contagious microbes poses a risk to patients, employees, visitors and society as a whole. Dangerous microbes often have a global spread pattern, which requires continuous readiness with effective, limiting measures against epidemics or pandemics. The book is focused on practical measures against severe hospital infections such as postoperative wound infections; intravascular, blood-borne infections; infections in lower respiratory tract, urinary tract, skin and gastrointestinal tract; and infections in neonates and premature and in other patients with impaired infection defence. A good hygiene is important to protect patients, visitors and employees against infections. Good hygiene routines, personal infection protection, cleanliness, textile v vi Preface treatment, sterility, disinfection and high professional hygiene standards for patient care increase patient safety and protect the working environment. Daily infection surveillance, infection detection and adequate contraceptive measures and informa- tion are required to stop the spread of infection. The book is intended to be an aid and an optimal standard in practical work to reduce the incidence of serious hospital infections and spread of infection. This increases the quality of patient treatment; patient safety is better taken care of, and infection control becomes a natural part of measures around hospital patients and employees. Prevention and Control of Infections in Hospitals: Practice and Theory is updated from earlier (1996, 1999, 2003, 2008, 2016) Norwegian handbooks in infection control, lastly published in 2016 (Elefantus forlag, Moss). Each chapter has a practical part and a background information and documentation part. Thanks to the following colleagues for professional advises and comments: Infection control nurses, Mette Rasch and Kjersti Hochlin; chief physician, Kjell Olafsen; and professor in medicine, PhD, Inggard Lereim. In addition, I am grateful to my family, friends and colleagues for friendly assis- tance and positive support during the writing period. However, my greatest and most enthusiastic fan, my dog, Tito, left forever in May 2018. Target groups: health professionals; doctors, nurses and other health profession- als; students in health-related subjects, hospital leaders and health agencies; and patients and their relatives.
