Context
The curriculum of Leiden Medical School, the Netherlands, consists of four preclinical and two clinical years. The preclinical semesters consist of 3- to 6-week blocks divided in themes [34] featuring different educational formats, such as formal lectures, small group tutorials, and self-directed learning. Early clinical experience is very rarely included. In years 3 and 4, clinical problems are the starting point of each theme.
This study was conducted in the block on MSD in the final 3 weeks of year 3. In this block, students learn to apply structured clinical reasoning in dealing with problems of the musculoskeletal system. This block implemented two RPL practicals, which are a novelty to the Leiden Medical School curriculum and subject of this study.
Throughout the year 3, none of the educational formats is obligatory. Students who wish to follow one of the small-scale educational formats such as small group tutorial and/or RPL practical must register and are consequently obliged to be present. The end-of-block test takes place the last day of the block. According to the medical school rules, however, students who undertake the block are not obliged to sit the end-of-block test at that particular moment.
Real patient learning practicals
Each of the two RPL practicals are planned after the formal lectures and small group tutorials concerning the subjects illustrated in the practicals. Each practical lasts 90 min and accommodates 15 students and 4 patients, thus assuring individual scale contact.
Due to the local situation, both RPL practicals are organized differently.
Patients who participate in the practical ‘Back pain’ are out-patients of the departments of rheumatology, orthopedic surgery, and/or patients under treatment of the local physical therapists) because of chronic low back pain and/or participants in the local training groups for patients with spondylarthritis. Students are obliged to take the history, perform the physical examination of the spine, decide on the differential diagnosis, and present their case to their peers. The practical is supervised by an experienced physical therapist. A small incentive is provided for the patients.
Patients who participate in the practical ‘Arthritis’ are members of a professional organization of arthritis educators which employs patients with RA in different phases of their disease [35, 36]. These patients are trained to give presentations and to teach medical students and general practitioners how to recognize and examine inflamed joints and teach about the consequences the disease has on their quality of life. The supervision by a senior staff member is limited to achieve optimal contact between students and patients. Patients receive hourly wages.
Recruitment of student participants
Two months prior to the start of the block, a lecture was given to the cohort of students who were going to participate in the MSD block explaining the purpose of the RPL practicals. In addition, an e-mail was sent to all students with the same content as the lecture. From that moment on until 2 weeks before the start of the MSD block, the practicals were open for enrolment.
Although medical ethics committees in Dutch academic medical centers are currently not required to evaluate this type of study, an ethical procedure was agreed on with the academic hospital’s medical ethics advisor. This meant that students were informed that their data (questionnaires and grades) would be anonymized, but not informed about the content of the questionnaires. They were invited to express any disagreement with the procedure and given the assurance that, if they disagreed, their data would be removed from the database. No disagreement was expressed by any of the students.
Students’ characteristics
The data concerning the gender and enrolment behavior in the (non-obligatory) educational modules in other blocks then in the block musculoskeletal disorders were collected by means of a short questionnaire presented to all students participating in the end-of-block test just after the test.
Primary outcome
Educational effectiveness
Students’ grades on the end-of-block test served as the measure of the educational effect of the practicals.
The test consisted of ten multiple choice questions (range 0–10 points) which examined the basic science knowledge and therapeutic problems (such as side effects of drugs) not directly related to low back pain or arthritis. Twenty extended matching questions (range 0–40 points) examined the knowledge of the musculoskeletal signs and symptoms and differential diagnostic considerations (12 out of 20 related either to low back pain or arthritis). To assess the in-depth acquisition of knowledge, one open question concerning arthritis was included to examine the capacity of the students to exercise the analytical problem-solving method taught during the block (range 0–13 points). In addition, the test included also one open question concerning a pharmacological approach to gout treatment (range 0–4 points). Final test score represents a sum of all subscores (range 0–63 points) with about 60% (37/63) of score representing knowledge concerning either arthritis or low back pain.
The final test grade was determined by method of Cohen–Schotanus [37]. It ranges from 0 (worst) to 10 (best), a score of six points or more means passing the exam.
To be able to correct for the potentially confounding volunteer bias, the test grades received by the students in the third year blocks preceding the MSD block (block abdominal problems, pulmonal and cardiac problems, and oncology) were collected from the medical school database (past test grades). These blocks were chosen because the level of difficulty was similar to that of the MSD block. The past tests’ grades range from 0 (worst) to 10 (best).
Secondary outcomes
Focus groups
Students’ opinions concerning their expectation of the early small scale patient contacts, experienced effects, and satisfaction with the practicals were collected by means of two questionnaires, Q1 and Q2. The questionnaires consisted of items generated by focus groups (focus group 1 and 2). Focus group approach has been shown to be effective in eliciting a rich variety of opinions from groups [38] and have been used in investigations similar to ours [20]. The members of the focus group were students who subscribed to practicals and agreed to participate. They were recruited by e-mail send out to all students who subscribed. This procedure resulted in a focus group of six female students (50%) and six male students (50%). The participants in focus group agreed that the results of the interviews will be reported anonymously and they received a small financial compensation for their efforts.
The focus group was scheduled twice before (focus group 1) and twice after the practicals (focus group 2) and lasted 2 h each. It was chaired by a moderator–educationalist (SV) who stimulated the discussion by asking additional questions and encouraged students to participate in the discussion. The focus group members discussed the following topics:
The focus group discussions were taped, transcribed literally, and subsequently analyzed by the researchers as described by Diemers [20]. Summaries were written and sent to the focus group students for their approval and comments. The qualitative data collected in the focus group meetings were analyzed in three phases as described by Miles and Huberman [39]. First, two researchers extracted separately the aspects of early patient contacts that were mentioned by the students. Second, they combined their analysis and decided about the list of aspects of early patient contacts as put forward by the students. Third, the transcript was analyzed by a third researcher in order to control whether the list of aspects of early patient contact was comprehensive. When this turned out to be the case, the aspects were converted into survey questions. They were piloted with two students to check whether the questions were understandable.
Students’ expectations
Q1 contained a list of 13 statements and students were instructed to select three which they regarded as most important.
Experienced effects and satisfaction with the practicals
Q2 consisted of the list of 12 statements concerning the subjective effects of both practicals. Students were asked to give a level of their agreement with each statement on a five-point Likert scale (0 = I strongly disagree, till 5 = I strongly agree). The practical ‘Back pain’ and the practical ‘Arthritis’ were assessed separately. In addition, four statements concerning the general satisfaction with the practicals were included. Again, students were asked to indicate to what extent they agreed with each statement on a five-point Likert scale.
The questionnaires were transcribed into NetQuestionnaire and e-mailed to all participants of the practicals. Q1 was sent 1 week before start of the block (and again the day before the start of the first practical), Q2 shortly after the end-of-block test (with a reminder 1 week later).
Statistical analysis
Data were analyzed using Statistical Package for Social Sciences version 16.0 based on intention-to-treat as initially assigned. The differences between the participants and non-participants were analyzed using Student’s unpaired t test or chi-square test where appropriate. The mean past test grades were calculated only when at least two out of three grades were available and were used in the linear regression analysis to account for potential confounders. P values below 0.05 were considered to be statistically significant. Effect size was calculated according to Cohen [40].
