Abstract
-
Purpose
This study investigated the attitudes of Korean medical students about patient safety to determine which perspectives required increased focus in terms of educational development.
-
Methods
Attitudes were assessed using the Patient Safety Questionnaire, a tool designed to measure attitudes toward patient safety among medical students. Questionnaires were distributed to 580 clinical year students across four medical schools in December 2018.
-
Results
A total of 300 returned questionnaires were used in the final analysis. More than half of all respondents agreed (i.e., gave more than 4 out of 7 points) with most items and thoroughly considered the concept of patient safety. However, many students misperceived several items (e.g., professional incompetence as a cause of errors, disclosure responsibility, the importance of patient safety in the curriculum, and situational awareness).
-
Conclusion
Attitudes toward patient safety are highly important due to their substantial impacts on behavioral decisions in the clinical setting. As such, patient safety education should be designed to place greater emphasis on proper attitude. This study’s findings should be useful for medical instructors who wish to determine the appropriate areas of curricular focus.

Key Words: Medical students, Patient safety, Medical education, Attitude, Surveys and questionnaires
Introduction
The hospital safety report titled “To err is human” was published in 1999 [
1]. Since then, increased attention has been paid to patient safety. For instance, there has been growing concern that various adverse events and medical errors can be prevented by increasingly engaging in patient-safety activities. As such, many hospitals strive to improve patient safety and quality through an accreditation evaluation system. There is also an increased need for both health care workers and medical students to directly learn about patient safety.
However, the idea of patient safety is still underdeveloped in the context of undergraduate medical education, especially true in Korea. One Korean study found that 73.7% of all respondents positively assessed the importance of medical error disclosure, but that less than 20% had received education or training on how to disclose errors and thus had negative perceptions of the error disclosure culture [
2].
The World Health Organization World Alliance for Patient Safety released its Patient Safety Curriculum for Medical Schools in 1999 [
3]. In 2017, the Korea Association of Medical Colleges published eight learning outcomes related to human and society-centered issues such as patient safety [
4]. As such, it is expected that patient-safety education programs will gradually increase in popularity. Before developing a patient safety curriculum, it is thus necessary to determine the related perceptions and attitudes of medical students. These perceptions should be thoroughly considered when developing educational contents. This study therefore aimed to identify baseline patient safety attitudes and educational needs using one validated survey instrument developed for use with medical students.
Methods
1. Attitude to patient safety questionnaire
The attitude to patient safety questionnaire (APSQ) was developed to measure attitudes about patient safety among medical students (reliability coefficients from 0.64 to 0.82) [
5]. Responses to each item were rated on a Likert scale ranging from 1 (strongly disagree) to 7 (strongly agree). Several items were reverse scored. Higher scores indicated more affirmative (or positive) responses to the concerned factors. The APSQ was translated into Korean according to established guidelines after obtaining permission from the corresponding author listed in the original study [
5,
6] (
Fig. 1). This study specifically used the APSQ version 4 (the most current) based on a recommendation from Lawton, the same individual.
This study was approved by the Institutional Review Board of Yonsei University Wonju Severance Christian Hospital (CR318102). A cross-sectional, self-administered questionnaire survey was anonymously conducted among 580 third- and fourth-year medical students from four total institutions in Korea during December 2018. Each had completed more than 1 year of their clinical clerkship and had received no prior formal instruction on patient safety (
Table 1). Questionnaires were distributed to all participants using an internet survey service (
https://ko.surveymonkey.com).
Attitude scores were presented as mean and standard variations or the numbers and ratio of agreement. Data were analyzed using IBM SPSS ver. 23.0 (IBM Corp., Armonk, USA).
Results
A total of 343 medical students responded to the survey (response rate of 59.1%). After excluding those with incomplete responses, 300 were used for analysis (180 third year students [60.0%], 175 males [58.3%]; mean age, 26.90±2.38 years). The survey received a Cronbach’s α of 0.720.
For general patient safety, over one-third of all respondents thought that most harm to patients was unavoidable. Over 60% were satisfied with and positively rated the patient-safety training they had received up until the time of survey. Most thought that it was important for undergraduate medical students to receive formal instruction on patient safety. However, 41% believed that patient safety could instead be learned through clinical experience after qualification, while only 31% indicated that it was effective to learn about patient safety issues before becoming qualified health professionals. More than half of all respondents indicated confidence about error reporting and the responsibility of disclosure while working in the capacity of a doctor. However, more than half agreed that junior team members should think carefully before initiating discussions about patient safety. Over 90% believed that human error was inevitable and that medical errors were not indicative of incompetence. Approximately one-third believed that most medical errors resulted from careless health professionals, while around two-thirds believed that medical errors could be avoided by paying more attention while at work. Regarding situational awareness, 72% believed that remaining vigilant about potential risks could actually be detrimental to patient safety (
Table 2).
Discussion
This study investigated attitudes about patient safety among Korean medical students with at least 1 year of clinical clerkship. Because respondents thus had no formal patient safety training, their perceptions may have been affected by information received from informal and/or hidden curricula in the clinical environment. Answers to several survey items seemed to require a change of perception related to patient safety among respondents.
More than one-third of this study’s respondents believed that most harm to patients was unavoidable. This was less than the percentages found by previous studies. For instance, about 70% of medical-student respondents to studies based in both Hong Kong and Iran agreed that most such harm was unavoidable [
7,
8]. Regardless, a substantial number of this study’s respondents require a change of perception.
The next item of note was error-reporting confidence. Although none of the respondents had received formal patient-safety instruction, more than half were confident in reporting errors regardless of who made them. This was similar to the findings of previous studies [
2,
9,
10]. However, over half were also afraid of initiating discussions as junior members. Similarly, a study among American medical students reported that 92% intended to report all encountered patient-safety issues, but that about 70% felt uncomfortable expressing concerns about their own mistreatment to superiors [
11]. These figures indicate that medical students are afraid of and reluctant to discuss mistakes with their superiors. This issue may be the result of hierarchies and/or the lack of error-disclosure training.
Most respondents were generous with their error inevitability estimates. Similarly, about 70% of respondents in previous studies agreed that even competent physicians make medical errors that lead to patient harm [
7,
8]. By contrast, they also seemed to believe that errors partially resulted from professional incompetence. That is, mean respondent scores were 3.83 out of 7 points for the item “Most medical errors result from careless health professionals.” This was similar to the scores found in a study among medical students from Hong Kong and Singapore [
10]. Furthermore, two-thirds of all respondents agreed with the item “If people paid more attention at work, medical errors would be avoided.” This also indicates a misperception similar to that involving the tendency to blame careless medical professionals in the above item. Many medical students in Hong Kong and Singapore appear to agree with this opinion [
10]. Furthermore, although only 11.7% of this study’s respondents believed that medical errors indicated incompetence, many more medical students in previous research projects have indicated the same [
10]. Based on the findings of both this and previous studies, there is still a tendency to blame medical errors on the individual (e.g., carelessness or paying less attention).
About two-thirds of all respondents believed that patient-safety issues could only be learned through clinical experience after qualification, which was also similar to the results of a previous study [
10]. Further, only 31.3% believed that it was effective to learn about patient safety before qualification. This is a very low percentage when compared to those found by previous studies [
7,
9]. This may be because Korean undergraduate medical education does not tend to focus on patient safety. Respondents did not seem to believe they could learn much about patient safety before qualification.
n terms of situational awareness, 72% of all respondents believed that remaining vigilant about potential risks could actually be detrimental to patient safety. While there are no previous studies with which to compare this figure, the results indicate that increased attention should be paid to the potential risks; efforts should be made to improve student misunderstandings in this area.
This study had a few limitations. First, data were only gathered from among four institutions, thus preventing generalizability. Second, since all data were collected anonymously and only minimal personal information was retrieved, it was not possible to compare the APSQ between the institutions. As such, we were not able to determine APSQ differences concerning hidden curricula at any of the four institutions.
Even with its limitations, our findings revealed several important issues. For instance, it is clear that medical students should become more familiar with patient safety through their curricula. They should be aware that they can initiate discussions as a team member despite the established occupational hierarchy. Finally, students should learn to both identify and improve potential risks and human factors while contributing to overall patient safety. It is now essential for future doctors to receive patient safety training. Attitudes toward patient safety are highly important in this context due to their substantial impacts on behavioral decisions in the clinical setting. This study’s results should serve as baseline data for use in developing patient-safety courses in the context of undergraduate medical education.
