Reducing medical device alarms by an order of magnitude: A human factors approach.

Anaesth Intensive Care 2021 Jan 2;49(1):52-61. Epub 2021 Feb 2.

Department of Anaesthesia, Intensive Care and Emergency, Academic Medical Centre Utrecht, Utrecht, The Netherlands.

The intensive care unit (ICU) is one of the most technically advanced environments in healthcare, using a multitude of medical devices for drug administration, mechanical ventilation and patient monitoring. However, these technologies currently come with disadvantages, namely noise pollution, information overload and alarm fatigue-all caused by too many alarms. Individual medical devices currently generate alarms independently, without any coordination or prioritisation with other devices, leading to a cacophony where important alarms can be lost amongst trivial ones, occasionally with serious or even fatal consequences for patients.

Measurement of Physiological Monitor Alarm Accuracy and Clinical Relevance in Intensive Care Units.

Am J Crit Care 2018 01;27(1):11-21

Halley Ruppel is a doctoral candidate, Marjorie Funk is the Helen Porter Jayne and Martha Prosser Jayne professor of nursing, and Robin Whittemore is a professor at Yale School of Nursing, West Haven, Connecticut.

Background: Alarm fatigue threatens patient safety by delaying or reducing clinician response to alarms, which can lead to missed critical events. Interventions to reduce alarms without jeopardizing patient safety target either inaccurate or clinically irrelevant alarms, so assessment of alarm accuracy and clinical relevance may enhance the rigor of alarm intervention studies done in clinical units.

Objectives: To (1) examine approaches used to measure accuracy and/or clinical relevance of physiological monitor alarms in intensive care units and (2) compare the proportions of inaccurate and clinically irrelevant alarms. Read More

Monge's disease, also known as chronic mountain sickness (CMS), is a disease that potentially threatens more than 140 million highlanders during extended time living at high altitudes (over 2500m). The prevalence of CMS in Andeans is about 15-20%, suggesting that the majority of highlanders (non-CMS) are rather healthy at high altitudes; however, CMS subjects experience severe hypoxemia, erythrocytosis and many neurologic manifestations including migraine, headache, mental fatigue, confusion, and memory loss. The underlying mechanisms of CMS neuropathology are not well understood and no ideal treatment is available to prevent or cure CMS, except for phlebotomy. Read More

A peripheral governor regulates muscle contraction.

Appl Physiol Nutr Metab 2011 Feb;36(1):1-11

Faculty of Kinesiology, University of Calgary, Calgary, AB T2N 1N4, Canada.

Active skeletal muscles are capable of keeping the global [adenosine triphosphate (ATP)] reasonably constant during exercise, whether it is mild exercise, activating a few motor units, or all-out exercise using a substantial mass of muscle. This could only be accomplished if there were regulatory processes in place not only to replenish ATP as quickly as possible, but also to modulate the rate of ATP use when that rate threatens to exceed the rate of ATP replenishment, a situation that could lead to metabolic catastrophe. This paper proposes that there is a regulatory process or "peripheral governor" that can modulate activation of muscle to avoid metabolic catastrophe. Read More

A precarious balance: using a self-regulation model to conceptualize and treat chronic fatigue syndrome.

Vincent Deary

Br J Health Psychol 2008 May 8;13(Pt 2):231-6. Epub 2008 Feb 8.

Institute of Health and Society, Newcastle University, Newcastle Upon Tyne, UK.

The problem posed by chronic fatigue syndrome (CFS) to the affected individual can be conceptualized, using Leventhal's common sense model, as a health threat to be encoded and coped with accordingly. The current paper adopts an alternative use of self-regulation theory. It is hypothesized that in CFS the health threat is no longer the illness, but anything that threatens to disrupt a precarious accommodation to it. Read More

Leadership character: antidote to organizational fatigue.

J Nurs Adm 2007 Oct;37(10):464-70

Connaughton Consulting, 9 Howard Street, Newton, MA 02458, USA.

Despite the tremendous gains nurse leaders have made in shaping the environment of care, an observable, dysfunctional dynamic resulting in organizational fatigue threatens the sustainability of those gains. At its peak, this dynamic cascades through all levels of nursing leadership, causing exhaustion, diminished decision making, and reluctance by nurses to assume formal leadership roles. In the worst case, this dynamic reaches the bedside with the potential to cause harm to patients. Read More

[Population problems of the present (author's transl)].

W Maier

Geburtshilfe Frauenheilkd 1977 Sep;37(9):796-9

At present objective predications on the trend of the population development at give economic and social conditions are very difficult since neither the axiom to report the facts correctly nor the axiom of neutrality in reporting determine what should or should not be included into the description of a situation. Common expressions such as population politics, marriage fatigue, contraction of the birth rate, generative behavior, contraception, termination of pregnancies, birth corntol capitalist economic order are loaded with emotions and can therefore not be considered to be neutral determinants in the description. In the field of demography and sociology no exact methodology and theory comparable to the natural sciences is existent. Read More
