The Implact of Working 8 vs. 12 Hour Shifts on Fatigue Among Nurses

In the past two decades, a lot of changes have been characterised in the healthcare working systems. One of these changes has been the assimilation of shift work systems and the flexibility in work schedules. The need for 24 hour care makes the healthcare professions to work with different shift systems such as 12 h, 8 h, 9 h or 10 hour shifts. However, the common shift work systems divide a 24-h day in two (12-h) or three (8-h) shifts. Nonetheless, this requires the staff to be adapted with the various forms of shift work schedules.

West, Ahern, Byrnes and Kwanten (2007) indicate that the new graduate nurses may have not worked full-time in the past; given that graduate nurses begin their career with a full-time job can lead to exhaustion. It was discovered that shift work leads to desynchronisation of physiologically determined circadian rhythms which has a major psychobiology effect and it is commonly perceived the effects of shift work contribute to graduate nurses attrition rate. The NGNs often have a high level of stress due to disturbed sleeping patterns, as they find to adaption to shift work or rotating work hours difficult. Eventually, it leads to feelings of lack of job satisfaction, exhaustion and spending of less time with their friends and family, which can eventually could lead to burnout (West et al., 2007).

Whether or not mandatory overtime is required varies from facility to facility. Like many other issues, there are both pros and cons to this topic. Witkoski,S, Sloane, D, and Aiken L (2012) did a study and concluded that nurses who worked 10 or more hours a shift were more likely to experience burnout and were dissatisfied with their jobs with an intent on quitting. Burnout can affect the quality of care a nurse provides to patients. Burnout can be the cause of a nurse not noticing subtle changes of patients which could potentially lead to patient neglect. Although there are cons to working long shifts there are some pros. When nurses work 12hour shifts, they often meet or exceed their weekly hours over the course of a 3day work week. Since they would only be working a three-day work week, it provides nurses with a better work-life balance and flexibility (Witkoski,S, Sloane, D, and Aiken L 2012), giving nurses more time outside of their job to do whatever they would like. Getting this kind of flexibility is great for nurses like myself who are either back in school or have families to take care of, or just need a little more time to recover and

Another cause of nurse fatigue is lack of adequate sleep. First, working 12 hour shifts means that nurses only have 12 hours to sleep and also conduct other activities of life outside the workplace, while other professionals have 16 or more hours for rest and social activities. This is the reason for the few hours of sleep recorded by nurses with some opting to not sleep at all but take short naps. These are

In the nursing profession, especially when working in a hospital, it is not uncommon to have 12-hour nursing shifts,

For some nurses, mandatory overtime can be an advantage due to financial instability but mostly mandatory overtime can cause fatigue, burnout, injuries, errors, inadequate sleep and deficits in performance. According to research working long hours which consists more than 40 hours a week or over 12 hours a day leads to an increased medication errors and patient mortality. The probability of making medication errors increases tremendously when nurses work longer than 12.5 hours a day. During surveys regarding reasons of overtime, 60 % of nurses stated that overtime was obligatory as part of their job, 29 % of nurses stated that they volunteered and 41% of nurses stated that they were “on call hours” (Bae, 2012)

The continued shortage of registered nurses will be a catalyst for the increasing stress placed upon practicing nurses now and in the future. Mandatory overtime has been an incessant problem within the nursing profession. When lives are at risk, alertness is a critical part of a nurse’s job performance. Fatigue impairs one’s judgement directly affecting patient and nursing safety or outcomes. This author’s typical six week work schedule consists of eighteen-twelve hour shifts, nine “required” twelve hour call shifts, and three-four hour back-up shifts. A nurse that accepts a patient assignment in the operating room cannot legally or ethically leave when their shift has ended without proper relief. Inevitably, without proper staffing departure is not an

Within the recent years, hospitals and medical facilities have been experiencing nursing shortages that necessitate more nurses to be present to compensate for the care needed to be given. This requires nurses to be dealt with imperative extended work hours along with their normal shifts with no denial or excuse accepted. Working extra hours are accompanied with negative effects that have an impact on the nurse, coworkers, and patients. A major concern that occurs with overtime is that nurses become fatigued or burnout. Fatigue that is experienced is a result of sleep deprivation from working overtime that is associated with arduousness neurobehavioral functioning

Throughout the years there has been more attention directed towards healthcare worker fatigue. More specifically, fatigue associated among night-shift nurses. The Joint Commission has found that lack of sleep from night shifts has contributed to increased errors, leading to poor patient outcomes (Gardner, Dubeck, 2016).

A nurse’s typical day isn’t without stress; it is usually a lot of complex planning, critical thinking, time management, an abundance of communications with all departments of the hospital, and documenting events that have happened throughout the day on their entire patient assignment. “Nurses who are mandated following the completion of their regular shift are often ill-equipped to continue working. They have not planned for that situation with: proper advanced rest, arrangements for

Patients in a hospital and/or healthcare facilities have to be cared for all day and all night, everyday of the week by nurses. The usual way to fulfill this need is to divide up the day into three 8-hour shifts. Different shifts have been put into place to help improve nurse satisfaction, decrease the nursing shortage and save the hospital money. The 24-hour day is made up of two 12-hour shifts; 12 hours in the day and 12 hours at night. There has been quite an ongoing debate over the years regarding this issue of nurses working over 8 hours in a single day. Many people, such as hospital nursing administrators, have reason to believe that working long hour shifts causes more errors in

The term 12 hour shift is used to refer to a two shift system associated with an extended working day, as supposed to an eight hour workshift. Twelve-hour shifts have become the normality and standard shift option for nursing over recent years across the United States (Harris, Sims, Parr, & Davies et al., 2014 p.606). Longer work hours are viewed as a positive impact on recruitment, potential financial savings, retention, and enhanced continuity of care (National Nursing Research Unit, 2013; NHS Evidence, 2010). However, it’s also evident that longer shifts result in nurse fatigue, errors, and reduced alertness. The concept of longer hour shifts have become quite the controversial topic among the healthcare system.

Limited attention has been paid to the hours worked by nurses, or the effects of these hours on patient safety (Rogers, 2008). Even though most nurses favor 12- hour shifts and overtime, it is associated with difficulties staying awake during times of duty, reduced sleep times, and triple the risk of making an error (Rogers, 2008). The most significant risk of making an error occurred when nurses were scheduled to work 12.5 hours or more.

To provide high-quality care for the patient it is essential for the nursing staff to have enough time for recovery from long hours of demanding work. Eight-hour shifts for hospital nurses have become a standard of the past. Nowadays, 12-hour shifts for three days a week have become typical in most hospitals as recommended by the Institute of Medicine (IOM) (Stimpfel, Sloane & Aiken, 2012). The length of the shifts and the working days; however, are often unpredictable due to increased demand for patient care and high census episodes. Nursing shortages, along with a weak economy, have left hospital nurses with no choice, then to work extended hours and overtime. Long hour shifts, as well as mandatory overtime, has become an increasing

The risks of making an error were significantly increased when work shifts were longer than twelve hours, when nurses worked overtime, or when they worked more than forty hours per week. (Trossman, 2009). Working longer hours in a high stress area will always increase the error rate. Designating an adequate number of RN positions to ensure nurses work an appropriate schedule without overtime and that their workload allows for breaks. Managerial staff must work to develop specific policies about the length of work times based on the setting, patient and provider needs. Those policies should limit nurses from working more than 12.5 consecutive hours. Provide education for all care providers on the hazards and causes of fatigue. Continue to document unsafe staffing conditions and work with others to change the current work culture so that it recognizes the effects of fatigue on patient safety, as well as the nurse.
