Abstract
Objective
There have been concerns about the workplace interpersonal conflict (WIC) among health-
care workers. As healthcare organizations have applied the incident reporting system (IRS)
widely for safety-related incidents, we proposed that this system might provide a channel to
explore the WICs.
Methods
We retrospectively reviewed the reports to the IRS from July 2010 to June 2013 in a medical
center. We identified the WICs and typed these conflicts according to the two foci (task con-
tent/process and interpersonal relationship) and the three properties (disagreement, inter-
ference, and negative emotion), and analyzed relevant data.
Results
Of the 147 incidents with WIC, the most common related processes were patient transfer
(20%), laboratory tests (17%), surgery (16%) and medical imaging (16%). All of the 147 inci-
dents with WIC focused on task content or task process, but 41 (27.9%) also focused on the
interpersonal relationship. We found disagreement, interference, and negative emotion in
91.2%, 88.4%, and 55.8% of the cases, respectively. Nurses (57%) were most often the
reporting workers, while the most common encounter was the nurse-doctor interaction
(33%), and the majority (67%) of the conflicts were experienced concurrently with the inci-
dents. There was a significant difference in the distribution of worker job types between
cases focused on the interpersonal relationship and those without (p = 0.0064). The doctors

tionship (34.1%) than not on it (17.0%). The distributions of worker job types were similar
between those with and without negative emotion (p = 0.125).
Conclusions
The institutional IRS is a useful place to report the workplace interpersonal conflicts actively.
The healthcare systems need to improve the channels to communicate, manage and
resolve these conflicts.
Introduction
Interpersonal conflict is an important type of conflict [1] that a variety of its nomen
exists, such as task, process, information, emotional and relationship conflicts [2–4
of conflict is often regarded as a negative term because individual interests are pe
opposed or negatively affected [5]. Recently, there have been concerns about wor
personal conflict (WIC) and its impact on the healthcare system and the workers [6
of individuals, including doctors, nurses, co-workers, managers and administrative
might have experienced conflicts [7]. The WICs were also commonly encountered
care units [8], operating rooms [9] and emergency rooms [10, 11]. These high-risk
areas often require intensive patient caring, timely decision-making, and multidisc
coordination among the workers [12]. WICs might be the consequence of poor com
tion [13], excessive work stress [14] or unsolved competing priorities of tasks [15]
oped, the WIC might, in turn, possess deleterious effects on the workers, such as in
with the team performance and reduction of staff satisfaction [16]. Furthermore, re
associated WICs with lower-quality patient care, higher rates of medical errors, a h
of staff burnout, and greater direct and indirect costs of care [17].
Since these consequences might compromise patient safety, we proposed that t
of the healthcare system might report interpersonal conflicts in the process of pati
when they report patient safety events. Many healthcare systems worldwide have
the incident reporting system (IRS) to understand the occurrence of patient safety
Since 2000, our institution has established an IRS for the workers in the hospital to
safety-related events in the hospital. Previous reports of the studies on the WIC in
care settings applied mainly questionnaire investigations and surveys [12, 19] whi
case-specific descriptions of the WIC were lacking, probably because reporting dire
the workers might require an adequate channel. Whether or no the IRS might also

jealousy, anger, anxiety, and frustrations [4]. Table 1 depicts the typology of the c
of WICs used throughout this study. In each incident, the investigators identified a
focus and property of conflict. Based on the text descriptions from the reporters an

Collection of data
The investigators collected the following data for analysis: dates, times, place, and
where the incidents and conflicts occurred, types and categories of the reported in

included the data regarding the types of the conflicts into analysis together with th

Our study has several limitations. First, since this study was retrospective and th
of this hospital did not provide a structured form for reporting WICs, we would miss
tion of WICs experienced by the healthcare workers who encountered the incident
also difficult to validate these WICs mainly based on the report contents; this was i
to the reports of incidents, which might be followed by further investigations as ind
ond, we did not know the presence of WICs during the patient care processes if the
incident reported. Although the establishment of a formal process for internal com
might be necessary, we believe that at least some of the WICs would be considere
jected for a formal reporting as complaints. Third, we did not investigate how the w
coped with WICs. Researchers had suggested a variety of types of behaviors for m
flicts in the context of “conflict management strategies” (i.e. a repertoire of reactio
flict that individuals may adopt depending on the situations) or “conflict managem
(implying a fixed tendency) [36]. Furthermore, approaches to managing conflict in
tions have been suggested [37]. Understand the conflict-managing behaviors of th
was beyond the scope of this study and might require other approaches in addition
dent report system here we used.
In conclusion, the institutional incident reporting system is a useful place to acti
the workplace interpersonal conflicts (WICs) related to task content and task proce
interpersonal relationship. The healthcare systems need to improve the channels t
cate, manage and resolve interpersonal conflicts.
