Abstract

Background

Recent educational initiatives by both the World Health Organization and the American Association of Medical Colleges have endorsed integrating teaching of patient safety and quality improvement (QI) to medical students. Curriculum development should take into account learners’ attitudes and preferences. We surveyed students to assess preferences and attitudes about QI and patient safety education.

Methods

An electronic survey was developed through focus groups, literature review, and local expert opinion and distributed via email to all medical students at a single medical school in the spring of 2012.

Results

A greater proportion of students reported previous exposure to patient safety than to quality improvement topics (79% vs. 47%). More than 80% of students thought patient safety was of the same or greater importance than basic science or clinical skills whereas quality improvement was rated as the same or more important by about 70% of students. Students rated real life examples of quality improvement projects and participation in these projects with actual patients as potentially the most helpful (mean scores 4.2/5 and 3.9/5 respectively). For learning about patient safety, real life examples of mistakes were again rated most highly (mean scores 4.5/5 for MD presented mistakes and 4.1/5 for patient presented mistakes). Students rated QI as very important to their future career regardless of intended specialty (mean score 4.5/5).

Conclusions

Teaching of patient safety and quality improvement to medical students will be best received if it is integrated into clinical education rather than solely taught in pre-clinical lectures or through independent computer modules. Students recognize that these topics are important to their careers as future physicians regardless of intended specialty.

Background

Medical errors are a significant cause of morbidity and mortality. For example, in the United States (US), medical errors are thought to be responsible for more than 90,000 deaths annually [1, 2]. Quality improvement (QI) has thus been a focus in the US and internationally in the past decade [2]. Both the World Health Organization (WHO) [3] and the American Association of Medical Colleges (AAMC) [4, 5] have endorsed increased teaching of patient safety and QI during medical school. Despite policy consensus, few medical schools have implemented curricula addressing these topics, and there is little evidence on the best methods to teach them [6].

The majority of literature only reports investigations of post-graduate teaching of these topics [7]. Within the sparse literature about undergraduate medical education, a recent systematic review of patient safety curricula in medical schools demonstrated that most teaching about patient safety occurred during the third year, varied in length from 4–30 hours, and was taught by clinicians, ethicists, and medical education experts [8]. The authors concluded that current teaching does not meet the goals established by the WHO and includes no controlled assessments of a standardized curriculum (though results of a pilot study of the WHO curriculum are pending). One study of medical students’ preferences for learning about patient safety demonstrated that three-quarters of students polled supported discussions of real life mistakes, and 70% supported internet-based learning. Blogging and role-playing were much less popular [9]. Other research demonstrates that much of student learning regarding patient safety is informal and occurs as students witness mistakes [10]. Some authors have proposed that witnessing the various ways in which mistakes are handled is an effective way to integrate patient safety training into the clinical years of medical school [11]. One UK school implemented a 5-hour module on patient safety that included lectures, videos, and role playing, and found a year later that knowledge and perceived control over safety had improved, but attitudes had not [12].

Much of the literature regarding teaching quality improvement to medical students is from curricula implemented at individual schools. One school demonstrated that student-led diabetes QI projects both improved the care patients received and taught students QI principles [13]. Another school integrated QI teaching throughout all four years with introductory material presented through lectures in years one and two, physician-guided QI projects with community preceptors during the internal medicine clerkship, and case studies in the fourth year [14]. In order to better inform the development of a curriculum at our medical school, we conducted a survey that collected information regarding students’ attitudes and learning preferences regarding patient safety and QI education. Specifically, we sought to examine students’ preferences on timing, setting, and pedagogical methods for teaching these topics.

Methods

Survey development

First, we conducted a literature search to guide a series of three focus groups with medical students and key informant interviews with local experts in multiple medical specialties. We then used our findings to develop a 34 question electronic survey that was distributed to all medical students at the University of North Carolina School of Medicine via email from April 20, 2012 to May 07, 2012. We collected information on where and when students felt they were learning about patient safety and quality improvement in the current curriculum, how and when students they would prefer to learn about patient safety and quality improvement. We also asked for opinions on the importance of quality improvement education. A full list of survey questions can be found in Additional file 1; results from the questions assessing student knowledge of patient safety and quality improvement topics will be reported in a separate article. The Office of Human Research Ethics of UNC exempted the study from review. Students consented electronically to participate in this research study. Students who completed the survey were eligible to be entered into a drawing to win an iPad.

Students were asked to compare the relative importance of patient safety and quality improvement knowledge to basic science and clinical knowledge using a scale of 1 to 5 where 1 indicated “less important” [than basic science or clinical knowledge], 3 indicated the “same importance”, and 5 indicated “more important”. Students were also asked to choose when they would most like to be taught about these topics and to rate various methods of teaching on a scale of 1 to 5 with 1 representing “not-helpful” and 5 representing “very helpful”. Students were asked to also rate the importance of quality improvement to different medical specialties. Students were not asked these questions regarding patient safety because we did not think that any student would feel that patient safety was unimportant. The importance of quality improvement to each specialty was rated on a scale of 1 to 5 with one being “not important” and 5 being “very important”. Finally students were asked to respond to the following statement: “Quality improvement is important to my future as a physician” on a scale of 1 to 5 where 1 indicated “strongly disagree” and 5 indicated “strongly agree”.

Data analysis

We report student characteristics, previous exposure to patient safety and quality improvement, preferences for curriculum timing and teaching method, and relative importance of patient safety and quality improvement in the medical school curriculum using frequencies or means with a standard deviation when appropriate. All analyses were completed in Stata 12 (StataCorp, College Station, Tx).

Results

A total of 450 of 790 students participated in the survey, for a response rate of 57%. Overall, the demographics of students who participated in our survey were very similar to the medical student population in general. Seven percent of participants were black and 46% were male (Table 1), compared to 8% black and 49% male students in the entire medical school. Thirty-nine percent of participants were in their preclinical years (first or second year), 47% were in their clinical years (third or fourth year), and 14% were classified as other (research year, MPH or PhD years, or leave of absence). In the entire medical school, 42% were in their preclinical years, 44% were in their clinical years, and 13% were classified as other. Among participants, thirty-three percent of students were currently working on or already had an advanced degree, including an MPH, PhD, MBA, or MS. An MPH was the most commonly pursued advanced degree (42% of advanced degree students). Thirty-seven percent of students planned to go into primary care. Ten percent intended to enter a medical or pediatric specialty. Twenty-eight percent planned to go into general surgery or a surgical subspecialty. Twenty-six percent of students intended to enter other specialties (anesthesia, dermatology, emergency, medical psychology, neurology, nuclear medicine, pathology, physical medicine and rehabilitation, preventive medicine, psychology, radiology oncology, or radiology).

When comparing the importance of patient safety knowledge to basic science knowledge, the mean of students’ ratings was 3.7 out of 5 (SD 0.90). When comparing the importance of patient safety knowledge to clinical knowledge, the mean of students’ ratings was 3.1 (SD 0.79). When comparing quality improvement knowledge to basic science knowledge, the mean importance rating was 3.2 (SD 0.88). When comparing quality improvement knowledge to clinical knowledge, the mean importance rating was 2.7 (SD 0.76).

Student preferences for the timing of this education are reported in Table 3 for patient safety and Table 4 for quality improvement. Preferences for all students are reported as well as preferences stratified by pre-clinical and clinical students. Forty-seven percent of students preferred for patient safety education to be taught during clinical rotations, and twenty-seven percent of students preferred to be taught during the clinical skills class during first and second year. Students also preferred teaching about quality improvement to occur during the clinical years with more than 50% of those surveyed choosing this time period.

Students rated independent study including reading and reflection about patient safety topics as least helpful (2.2 out of a maximum of 5). Independently completed computer modules were also rated low with a mean of 2.4, followed closely by a large group lecture (2.6). The two most helpful methods of learning about patient safety were real-life examples of mistakes presented by a physician (4.5) or by patients (4.1) (Table 5).

Students were also asked to rate methods of quality improvement teaching on the same scale of not helpful (1) to very helpful (5) (Table 6). As seen with patient safety teaching, the methods rated least helpful were independent study with reading and reflection (2.3), independent computer modules (2.4), and large group lectures (2.6). The highest rated methods were physician-guided quality improvement projects on a real panel of patients (3.9) and real-life examples of quality improvement projects presented by physicians (4.2).

Finally, students were asked to rate the importance of quality improvement to different medical specialties (Table 7). Perceived importance ratings of QI to all specialties listed were between 4.2 and 4.7, except for dermatology, which received an importance rating of 3.9 (Table 7). There was no significant difference between pre-clinical and clinical students’ opinions. Finally, when students rated the importance of quality improvement to their future career the average score was 4.5. Differences were examined between pre-clinical vs. clinical student categories, and by intended specialty; none of these comparisons proved to be significantly different.

Discussion

Within the last decade there has been a significant push to teach medical trainees about patient safety and quality improvement, in part prompted by landmark publications by the IOM [1, 2]. While there has been an accumulating body of research regarding post-graduate education in these areas, less has been published regarding medical student education [7]. Our survey revealed that more than a decade after the IOM reports most medical students feel they are exposed to patient safety in school, but less than half reported having been exposed to quality improvement. Students do, however, recognize the importance of these topics, despite their varied exposure. In general, most students prefer to be taught these topics in clinical settings and using the most “hands-on” approaches possible. Lectures and independent study methods were very unpopular for learning both topics, while discussions of “real life” mistakes or participation in QI projects on real patients were rated as most helpful.

Student attitudes and learning preferences are important to consider when implementing a major curriculum change. An understanding of student attitudes helps educators predict whether a curriculum is liable to have “buy-in” or face resistance. If resistance is anticipated, education about the importance of the topic may be needed [15]. An understanding of learning preferences, although not the only factor to consider, can assist in prioritizing which pedagogical methods are most likely to be effective [16, 17].

Interestingly, in contrast to the results by Thain and colleagues, who found that 70% of students preferred internet-based learning for patient safety, our students did not believe that computer modules would be helpful [9]. Our results are similar to Thain and colleagues in that students rated discussions of real life mistakes as most helpful. Likewise, students preferred quality improvement education to be more applied than simulated, preferring involvement in real QI projects to virtual simulation, independent study, or work on a “fake cohort” of patients. Perhaps the divergence in students’ attitudes towards internet-based learning is cultural as the studies were conducted in Singapore and the USA, respectively.

It seems clear that to engage medical students in these important topics, they should be delivered in as real an environment as possible. As some have suggested, the slow integration of these topics into medical curricula may be due to the lack of available educators or high cost [18]. Thus, involving medical students in “hands-on” QI projects may be cost-prohibitive, especially when medical school classes are large. However, a few medical schools have managed to involve medical students through introductory lectures early in medical school followed by participation in physician-guided QI projects during their third and fourth years. The results of these curriculum designs appear promising [13, 14].

Our survey demonstrated broad student support for student participation in ongoing quality improvement projects. Additionally, research has shown that involving medical students in QI projects can not only aid student learning, but can also improve the quality of care for patients [13]. Thus integrating these projects into medical school curricula may be an effective use of resources on multiple levels.

Teaching obviously requires teachers with appropriate knowledge and skills in the topic. Therefore, faculty development is a crucial step before QI and patient safety curricula can be widely implemented. Given that post-graduate education has been quicker to integrate these topics into their education, perhaps soon there will be a new pool of faculty members armed with the knowledge necessary to teach medical students patient safety and quality improvement. Patient safety education may be aided by the help of health care administrators who have experience in the topic as one school in China demonstrated [19].

A feasible first step in patient safety education, favored by our students, and validated as an effective method by at least two schools, is the use of standardized patients to learn the art of error disclosure [20, 21]. Medical students work with Standardized Patients (SPs) in the United States for the USMLE Step 2 CS, and most medical schools already have SPs integrated into portions of their curricula. Patient safety learning can also utilize the clinical years to turn the informal witnessing of mistakes into more formalized debriefing sessions and discussions about conflicting ways of dealing with errors as they occur [11].

Our study is limited by the potential for non-response bias. Students who answered this survey may have been more likely to be interested in patient safety and quality improvement. This greater interest may have led to inflation in the rating of attitudes and “helpfulness” ratings of the various teaching methods. However, responders were demographically similar to non-responders, which gives us some reassurance that non-response bias is likely to have had minimal effect. Additionally, more than half of the entire student body responded to the survey. Still, as this survey only represents the opinions of students from one US medical school, their preferences may not be generalizable to other schools.

Conclusions

Overall our survey demonstrated that students are in favor of a new curriculum that formally addresses patient safety and quality improvement. Additional comments at the end of the survey left by students were overwhelmingly supportive. One comment in particular captures the essence of the overall student opinion: “Any situation that causes us to act, rather than simply read from papers or listen to lectures is going to be helpful. I learn by doing.” Medical schools should work to integrate these topics into clinical experiences rather than making them separate experiences in order to emphasize the importance of safety and quality to one’s career as a physician.
