Medical resident work hours

Medical resident work hours is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Medical resident work hours rather than just read about it. In short: Medical resident work hours refers to the (often lengthy) shifts worked by medical interns and residents during their medical residency. As per the rules of the Accreditation Council for Graduate Medical Education in the United States of America, residents are allowed to work a maximum of 80 hours a week averaged over a 4-week period.

Reference excerpt

Medical resident work hours refers to the (often lengthy) shifts worked by medical interns and residents during their medical residency. As per the rules of the Accreditation Council for Graduate Medical Education in the United States of America, residents are allowed to work a maximum of 80 hours a week averaged over a 4-week period. Residents work 40–80 hours a week depending on specialty and rotation within the specialty, with residents occasionally logging 136 (out of 168) hours in a week. Some studies show that about 40% of this work is not direct patient care, but ancillary care, such as paperwork. Trainee doctors are often not paid on an hourly basis, but on a fixed salary; in some locations, they are paid for booked overtime. Limits on working hours have led to misreporting, where the resident works more hours than they record. Medical resident work hours have become a hot topic of discussion due to the potential negative results of sleep deprivation on both residents and their patients. According to a study of 4,510 obstetric-gynecologic residents, 71.3% reported sleeping less than 3 hours while on night call. In a survey of 3,604 first- and second-year residents, 20% reported sleeping an average of 5 hours or less per night, and 66% averaged 6 hours or less per night. In a recent landmark study published in May 2021, the World Health Organization and the International Labour Organization estimated that globally in 2016, more than 745,000 persons died as a result of having a heart disease event or a stroke attributable to having worked long hours (here defined as 55 or more hours per week), making exposure to long working hours the occupational risk factor with the largest disease burden.

Causes of high workloads Medical residencies usually require lengthy hours of trainees. Trainees are traditionally required to be present for set shifts, with the ending time of the shift dependent on momentary circumstances. The flexibility of this system makes it easy to abuse. Junior doctors often lack bargaining power and have difficulty changing employers. This leaves them with little say over their working conditions. Critics of long residency hours note that resident physicians in the US have no alternatives to the position that they are matched to, meaning residents must accept all conditions of employment, including very long work hours, and that they must also, in many cases, contend with poor supervision. This process, they contend, reduces the competitive pressures on hospitals, resulting in low salaries and long, unsafe work hours. The National Resident Matching Program has also been accused of deliberately limiting the available residency posts, thus decreasing the demand for residents, despite work for many more residents being available. In emergencies and in chronically understaffed health systems, all staff, including junior doctors, may be overworked. In some cases, excess work may be disproportionately assigned to junior doctors. There are financial incentives for overworking junior doctors. Since the least-experienced staff are usually paid less, it is cheaper to assign paid overtime to them. Deliberate understaffing and paid or unpaid overtime for junior doctors is thus used to reduce costs for medical facilities, although this may also reduce quality of care, which can be expensive. The medical culture has also been blamed. "Generation-bashing", where senior doctors look down on junior doctors who work fewer residency hours than they did, can push junior doctors to overwork. A desire for formal recognition, such as promotion, may also be important. A higher "entry barrier", with work conditions poor enough to burn out some residents, may be actively desired. There is also a belief that long hours do, or can, improve training. The ability to follow a patient from admission through the next 30 or 40 hours may be valued more than observing several patients for shorter periods. The desire to continue caring for a patient frequently leads doctors to work for longer than is permitted.

Effects on health

Effects of sleep deprivation on residents The evidence for harm to people who are deprived of sleep, or work irregular hours, is robust. Research from Europe and the United States on nonstandard work hours and sleep deprivation found that late-hour workers are subject to higher risks of gastrointestinal disorders, cardiovascular disease, breast cancer, miscarriage, preterm birth, and low birth weight of their newborns. It has also been shown that slow-wave sleep assists in clearing out toxins that build up during the day. Consequently, the disruption of slow-wave sleep increases the level of amyloid-beta, a protein aggregate commonly found in Alzheimer's, present in cerebrospinal fluid the following morning. Chronic sleep deprivation and the resulting fatigue and stress can affect job productivity and the incidence of workplace accidents. There are also social effects. Married fathers in the United States who work fixed night shifts are 6 times more likely than their counterparts who work days to face divorce; for married mothers, fixed nights increase the odds by a factor of 3.

Worked examples

Example 1 — a first encounter with Medical resident work hours

Start with the simplest possible case. Write down what Medical resident work hours claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Medical resident work hours before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Medical resident work hours ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Medical resident work hours

In research: Medical resident work hours appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Medical resident work hours in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Medical resident work hours is common in secondary-school and first-year university syllabi. It links to neighbouring topics Medical education in the United States, Medical regulation in the United States, Working time, so understanding it makes those chapters shorter.
In everyday life: Look for Medical resident work hours outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
