Han and Chung: The perception of medical residents and faculty members on resident duty hour regulation



This study investigated the perceptions of medical residents and faculty members before the implementation of the duty hour regulation in December 2017.


A survey was administered to 263 residents and 358 faculty members in the Chonnam National University Hospital. The subjects were given a self-administered structured questionnaire designed to measure their perspectives on duty hour regulation. They were also asked to answer an open-ended question regarding their expectations or concerns regarding duty hour regulation. The response rates were 50.2% for residents and 24.0% for faculty members.


Residents and faculty members regarded the improvement of junior residents’ well-being favorably, but had conflicting views regarding senior residents. Residents expressed difficulty in completing unchanged workloads within the limited time, while faculty members were more concerned about worsening patient safety due to the discontinuity of care and insufficient resident education.


Medical residents and faculty members had differing concerns regarding duty hour regulation. Further studies and the development of future policies should be considered to improve resident education and patient safety within the limited duty hour regulation.


In December 2017, the resident duty hour regulation was first implemented in Korea; it was designed to protect the rights of residents, contribute to high-quality resident education, and improve patient safety. However, its effects on patient safety and resident education remain controversial. Residents and residency program directors, who already have work-hour restrictions, believed that quality of patient care and resident education would be negatively affected by the regulation [1,2].
In Korea, several reports have warned of the existence of substandard working environments, including excessive workloads, sleep deprivation, and emotional exhaustion [3,4]. Therefore, the regulation was implemented and teaching hospitals in Korea were given a 1-year grace period to prepare for the new training environment. Duty hour regulation limits work hours as follows: maximum hours of work are limited to 80 hours per week, averaged over 4 weeks, including nightshifts; maximum hours of consecutive duty do not exceed 36 hours; and minimum off-duty time between duty shifts should be guaranteed 10 hours. Despite the implementation of this regulation, there has been a report evaluating the superiority of a night float system with regard to duty hours [5].
In order to ensure that these new changes in graduate medical education develop into a successful system, we should listen to residents and faculty members who have first-hand experience of the duty hour regulation. Teaching hospitals comprise loosely coupled organizations whose members, including residents and faculty members, have strong autonomy to set their own priorities and resist control by authorities [6]. To improve the training environment, we investigated their perception of duty hour regulation, how they have accepted it, and what they want out of it. The specific research questions were as follows: (1) How did the residents and faculty members perceive the new duty hour regulation before the law was enforced? (2) What did they expect or what were their concerns, regarding this regulation, in preparation for the new training environment?


A total of 263 residents and 358 faculty members were recruited from the main and Hwasun regional branches of the Chonnam National University Hospital. The study was approved by review by the Chonnam National University Hospital Institutional Review Board (IRB approval no., CNUH-2017-003).

1. Data collection

We developed a self-administered structured questionnaire in light of the results of former research [1,2]. The questionnaire was sent by post to each department of the hospitals prior to the implementation. The questionnaire consisted of three sections. The first section asked for demographic information. The second section asked about the respondents’ levels of agreement on each item of resident duty hour regulation, on a 5-point Likert scale, and asked for their perceived effects of duty hour regulation on quality of life, resident education, and patient care. These questions required either a positive, neutral, or negative response. The third section asked about the respondents’ expectations or concerns regarding the new regulation; this was an optional and free-text response question.
Data were collected between November and December 2017 which was the last month of the 1-year grace period. All data were provided anonymously.

2. Data analysis

We performed a chi-square test and Student t-test to compare the general characteristics of the participants and their perceptions about the resident duty hour regulation between residents and faculty members. All analyses were performed using IBM SPSS Statistics ver. 25.0 (IBM Corp., Armonk, USA).


We received 132 responses (50.2%) from residents and 86 responses (24.0%) from faculty members. The demographic information of the respondents is summarized in Table 1.

1. Level of agreement and perceived effect of duty hour regulation

The residents and faculty members positively answered in agreement on each item of resident duty hour regulation (Table 2). The perceived effects of duty hour regulation on quality of life for junior residents were favored by both residents and faculty members. However, those for senior residents were contrary to each other (p<0.001) (Table 3). Residents and faculty members had diverse opinions about the effects on patient care and resident education. Faculty members were more worried about the negative effect on continuity of patient care than medical residents (p=0.007). The majority of the residents believed that the quality of resident education and the preparation for a more senior resident role would remain unchanged. Conversely, faculty members had more negative responses, expressing that these factors would be made worse by the new regulation.

2. Expectations or concerns regarding duty hour regulation

The most popular opinion of residents and faculty members alike was to reduce the workloads of residents, instead of merely restricting their duty hours. Residents argued that it was more difficult to complete unchanged workloads within the limited duty hour. It was harder to assign unchanged workloads to residents if their specialty was unpopular. Both groups suggested that a professional workforce, including hospitalists or physician assistants, should be recruited to share the work burden.
Residents anticipated that duty hour regulation would help them to more easily secure off-duty time and time for studies. However, faculty members were more concerned that the discontinuity of patient care would hamper professional development, including the responsibility of patients, and eventually cause the deterioration of patient safety. Duty hour regulation could impede resident education because of fewer clinical experiences as a result of their shortened time and the segmented process of patient care, especially when attending operations that take a long time. Faculty members recommended that there should be education programs or research activities outside of the hospital for residents, to compensate resident education and ultimately, improve patient safety.


Our study showed that residents and faculty members agreed on the positive effect on junior residents’ well-being. However, they had differing viewpoints about the effects of the regulation. Residents expressed the difficulty of completing unchanged workloads within the limited hours, while faculty members were more concerned about worsening patient safety due to the discontinuity of care and insufficient resident education.
Residents complained of the difficulty in making a schedule without exceeding someone’s working hours, given a fixed number of residents. Residents expected that senior residents’ quality of life would be worse since senior residents could assume part of the work from junior residents, as compared with the practices of previous training years. To ameliorate their intense and concentrated workloads, they suggested that existing members should be redistributed, and that a professional workforce should be recruited. The recruitment of new members of the workforce would be essential to sustain a successful change of graduate medical education if labor costs may be offset by the reduction in costs related to preventable adverse events [7].
Faculty members expressed concerns that resident education would be negatively affected by decreased opportunities for clinical exposure. Consequently, duty hour regulation would result in delayed preparation for more senior resident roles and increased duration of training [1]. However, duty hour regulation was not associated with differences in resident examination performance [8]. Residents, in our study, were rather delighted to secure off-duty time and time for studies. Indeed, the residents perceived that their opportunities for learning were influenced by the content and organization of duty hours, rather than the volume of duty hours [9]. A safe and humanistic education environment would be the most important factor for residents’ learning, given a high level of well-being and sufficient high-quality supervision [9].
In our study, residents and faculty members had mixed opinions regarding the effects of the regulation on patient care. Despite concerns about increased handoffs, discontinuity of care, and decreased ownership of patients, there have been no objective values of worsened patient outcomes, in accordance with previous research [8,10]. High levels of emotional burnout and depression have been connected with more medical errors and poorer clinical performance [1,8].
This study has several limitations. First, this research was an observational study to survey participants’ perceptions of duty hour regulation. Thus, there was potential for interpretation and recall bias. The study may have been affected by selection bias because it was both anonymous and voluntary. Second, it was restricted to the main and regional branches of a teaching hospital in one province, and therefore should not be generalized. However, it represents a very meaningful first step towards investigating the perceptions of residents and faculty members on the duty hour regulation. These results would be useful to identify and consider their desires regarding the management of the residency training program considering our medical environments, although the numerous reports of other countries might be a good guide to indicate the long-term consequences of duty hour restrictions [1,2,8-10].
Further research should be conducted to examine changes in perceptions after the implementation of the regulation. A qualitative study could also be undertaken to gain a broader understanding of perceptions of the duty hour regulation. A nationwide survey will be required to determine the effects of the duty hour regulation on resident well-being, patient outcomes, and resident performance, all of which are relevant to our training environment.
In conclusion, residents and faculty members had differing concerns regarding duty hour regulation. Further studies and the development of future policies should be considered to improve resident education and patient safety within the limited duty hour regulation
