The development team comprised 22 professionals specializing in cancer care plus French faculty members. We divided the team into 2 subgroups: a teaching group and a project management group. Among the 22 professionals, 12 worked in a hospital, 8 worked outside the hospital (in the community), 1 specialized in the hospital–community network (and worked in the hospital and the community), 1 was an industrial pharmacist, and 1 worked within an institution (ie, Director of a Regional Health Agency).

The teaching team for the course was composed of 8 coordinator lecturer surgeons, radiotherapists, internal medical practitioners, clinical pharmacologists, a clinical researcher, and supportive care specialists; 14 other lecturers (senior nurses, hospital pharmacists, and physicians); and 8 general practitioners, dispensary pharmacists, physiotherapists, nurses, dentists, research and development managers from the pharmaceutical industry, patients, and caregivers, who provided testimonies. Teachers were volunteers and were chosen by the teaching council (ie, the course manager that introduced the SPOC, the project manager, and the Dean of the Medical Faculty of Toulouse III University). Among the 8 coordinators, we chose 6 lecturers for the 6 weeks of the SPOC, as they were specialists at our hospital (Institut Universitaire du Cancer de Toulouse-Oncopole, Toulouse, France). These 6 coordinators then chose 10 other assistant lecturers to help explore the specialties.

The teaching team and the SPOC project were managed by the project management team, which comprised 4 professionals: a project manager to oversee the project, a social officer to manage registration and forum moderation, a communications officer in charge of advertising, and a technical officer responsible for managing the multimedia elements.

Participation in the course was open to all people involved in the management of cancer patients. Our public population included health students (medical and paramedical), health professionals, and members of patient associations.

Two sessions of the SPOC have been available since October 2016, but the offerings were not linked. Registration in the first session was not needed to register in the second session.

We initially offered open access to the SPOC to facilitate dissemination of knowledge, but then decided to restrict registration to students and professionals, and then, only after verifying their motivation, we also included volunteers from patients’ associations.

We limited the first offering of the course to 600 participants, whereas we did not limit inclusion for the second offering. The first SPOC opened its virtual doors on October 24, 2016, and the second on March 27, 2017. Participants registered on an outside platform and provided their characteristics. The registration home page also asked for the student’s identification number or health professional identification number [13].

We built the SPOC according to previously published information [14,15]. We planned 2 offerings of the course, each lasting 6 weeks, plus 3 supplementary weeks to provide adequate time for students to prepare for the final examination or to finish chatting on the forum.

The course covered 6 topics—week 1: individual health care plans; week 2: cancer surgery; week 3: ionizing radiation; week 4: cancer medicines; week 5: clinical research; and week 6: oncological supportive care (Figure 1).

These 6 topics were chosen by the teaching council. For each topic, at least 5 subthemes were determined in collaboration with the coordinator lecturer, and each subtheme was the subject of a video, as detailed in Table 1.

Each week, depending on the video that was shown, between 1 and 3 quizzes were presented (with a total of 75 quizzes for the 6 weeks). These consisted of multiple-choice questions with answers of true or false, fill-in-the-gap exercises, and drag-and-drop exercises.

The training was personalized: each participant could learn step-by-step and could choose his or her own learning pace. They could stop or rewatch videos, which was especially pertinent for difficult topics, or students could accelerate through a video if they were familiar with the subject. After the first session, we modified interactive parts of the forum and some of the exercises for the second session.

To create social and active online communication, we opened a forum and links to Facebook, Twitter, and LinkedIn for discussion. We had 23 groups of 10 or 11 participants each who worked on 3 subjects: the new secondary effects of a drug, clinical trials, and supportive care. A webinar was suggested after 3 weeks (in the middle of the SPOC). Participants could then direct questions directly to a professional in the field.

Throughout the SPOC, we evaluated each participant’s satisfaction through a questionnaire that included 29 questions, which were validated by the teaching and communication teams. Each question could be answered using a 4-point scale. Categorical data were presented using numbers and percentages. Participants completed an evaluation form so that we could assess their characteristics and their expectations before starting the SPOC. Participants could also complete a satisfaction feedback form after the course. The SPOCs were certified for continuing professional development (CPD) by the Développement Professionnel Continu, according to French national recommendations (Haute Autorité de Santé). A final examination was suggested for each course. Each participant obtained a continuing health training certificate if their final score was greater than 50% (or 10/20), as recommended for CPD programs. The feedback form was designed by the project management team according to the French national recommendations for CPD programs.

We evaluated the success of the SPOCs according to the completion rate (percentage of participants who completed the 6-week course out of the total number of participants registered), success rate (percentage of participants who successfully completed the examination), and commitment rate (percentage of participants who completed the 6-week course out of the total number of participants who completed the first week of the course). We performed descriptive analyses on our population. All qualitative variables are described by numbers and percentages. Categorical variables are expressed as counts and frequencies (percentages). Quantitative variables, following a Gaussian distribution in our study, are described by their means and standard deviations. We used the chi-square test to compare results between the 2 SPOC offerings.

Our SPOC sessions were hosted by a private Web platform that respected the ethical considerations for personal data, in agreement with French law. The details are available on the FunCampus [16] and 360 Learning websites [17].

Students provided information outside these platforms (eg, through our anonymous surveys). Since we did not consider this to be personal data, in agreement with French law (Commission Nationale de l’Informatique et des Libertés), we did not need any ethical approval [18].

To compare the overall cost of the SPOC and the theoretical costs of comparable face-to-face education, we calculated the overall cost of the online course compared with traditional classroom teaching for the same number of participants (eg, 1000 participants). We assumed a group of 25 participants in a traditional classroom. We calculated the point where online education became more effective.

The overall cost included salaries of a project manager, course director, teachers, a community manager, a beta tester, legal assistance, a communication department, and an administrative partner (a private enterprise, specific to a SPOC).

The first course session began on October 24 and finished on December 31, 2016. It lasted 6 weeks plus 3 supplementary weeks to allow adequate time for students to prepare for the final examination.

Among the 600 participants, 176 completed the questionnaire, which provided the following data. Most participants were aged 31 to 45 years (range 18 to >50 years); 68.4% (120/176) of participants were aged over 46 years. The paramedical group was well represented, with 26.1% (46/176) being nurses. A total of 24 (13.8%) were pharmacists, pharmacy students, and dispensary pharmacists, and 17 (9.7%) were in the medical field (doctors, medical students, and residents). The completion rate of this SPOC was 36.0% (216/660), the success rate was 66.0% (396/600), and the commitment rate was 72.0% (432/600).

The second session ran between March 27 and May 31, 2017. The course ran for 6 weeks plus 3 supplementary weeks to enable adequate time for students to prepare for the final examination.

We modified some elements of the SPOC for the second session, as follows. (1) Responding to the feedback form completed in the first SPOC, we rewrote some sentences and modified the format of the collaborative exercises. (2) To ensure that the second SPOC suited the participants, we created a beta test group from the first SPOC to test the format of the exercises and to detect any technical problems before starting the second SPOC. (3) A total of 6 volunteers from the first SPOC participated in moderating the forum, creating collaborative exercises, and encouraging engagement of the participants in the collaborative exercises. (4) We modified the format of the collaborative exercises. The initial format was a pluriprofessional discussion on one predefined subject, but there were few interactions. Each participant answered the question without considering the comments from the other participants. Thus, we switched to an exercise that fostered more collaborative homework. Moreover, participants had to evaluate the homework of the other groups.

In this second course session, of the 975 participants, 270 completed the questionnaire, which supplied the following data. Most participants were aged 31 to 45 years. The age distribution was the same as in the first course. Of the paramedical group, 42.9% (116/270) were nurses. A total of 124 (45.9%) were pharmacists, pharmacy students, and dispensary pharmacists, and 10 (3.7%) were medical students. The completion rate was 34.8% (339/975) the success rate was 76.9% (550/975) and the commitment rate was 56.9% (555/975).

Of the total 1574 participants, 446 completed the evaluation questionnaire. Most participants were aged 31 to 45 years. There were 121 paramedical and social workers (including 56 nurses), 131 pharmacists, 80 participants from the medical field (including 26 physicians), 53 participants from patients’ associations, 28 teachers, 17 administrative or industrial, 13 students, and 3 others (nonclassified) (Table 2).

Registration was open to participants from all countries as long as they could understand the French language; most participants lived in France (n=427, 95.7%) (Figure 2). Other participants mainly lived on African continent (n=6, 1.4%), the United States (n=6, 1.4%), or Canada (n=4, 0.9%) (Figure 3).

Among the participants, 24.9% (111/446) had an independent medical practice, 38.9% (173/446) worked in a public institution, and 36.9% (165/446) worked in a private institution.

Among the participants, 85.9% (383/446) thought they had learned new information (moderately: 179/446, 40.2%; considerably: 205/446, 45.9%), 90.8% (405/446) felt their expectations had been met (fully: 204/446, 45.7%; relatively: 201/446, 45.1%), and 89.9% (401/446) considered the course had a positive impact on their professional practice as a caregiver (Figure 4). The completion rate was 36.02% (567/1574), the success rate was 71.98% (1133/1574), and the commitment rate was 64.99% (1023/1574).

Many participants expressed their satisfaction (or dissatisfaction) by posting comments on the forum during the courses. In total, 2812 comments were posted on videos and the forum: 2367 “liked” (the first session) and nearly 84.9% (379/446) considered it positive, with 15% suggesting improvements.

There was an initial and fixed high cost to developing the SPOC, independently of the number of participants. The only costs that could be modified were the animations, the forum, and the registration platform. In contrast, traditional face-to-face classrooms have a low cost initially, but this then increases according to the number of students. For example, for 1000 participants, the overall cost of the SPOC was €148,000, versus €154,000 for face-to-face education (€154 per student). If we assumed a classroom with 25 students, the point where online education became more effective was 950 participants (Figure 5).

This SPOC was a positive experience with a completion rate of 35.5%, a success rate of 71.5%, and a commitment rate of 64.7%. Among the 1574 participants, most were aged 31 to 45 years and were paramedical practitioners (nurses, pharmacists). Most (90.4%) considered that this course had a positive impact on their professional practice. The cost effectiveness of this online education became more effective at more than 950 participants.

This SPOC was an innovative oncological teaching method and had a high completion rate (35.5%). In general, on MOOC platforms, the completion rates are between 5% and 10% [7]. Hoy suggested that, in medicine, MOOCs could be used in continuing medical education [19]. However, few medical universities use this kind of teaching [4,5,15,20-22].

A high completion rate (38%) was observed in an Australian MOOC on dementia: 4409 registrants took part in discussion boards and 3624 completed the course [23]. In addition, a French MOOC that opened in 2016, the Diagnostic Strategies of Cancers, had a satisfactory completion rate (23%) [4,5].

From that experience, we decided to design a SPOC that was a modified MOOC. In our SPOC, the number of registered participants and the completion rate in the second session (341/975, 34.9%) were similar to rates in the first session (261/600, 36.0%). This demonstrated that students’ interest in this SPOC remained high and was not only an initial enthusiasm for a new teaching method. Also, the large difference in completion rates between MOOCs and our SPOC could be because SPOCs are developed for a targeted audience and are, therefore, able to better suit the educational needs and interests of their participants [3-5,7].

In the MOOC Diagnostic Strategies of Cancers, there were 2 types of learners: students in health and biology, and members of the general public. Of the participants, 71% chose to go on to student teaching. Of the 5285 participants from 81 different countries, 1237 (23%) were successfully certified [4,5].

In our SPOC, we targeted the participant profile at medical and paramedical caregivers to create a stronger link between professionals sharing an interest in oncology. We found that nurses were the main group represented in the first session, whereas pharmacists were the main group in the second session. This could be because more information was delivered by the pharmaceutical community about this SPOC after the first course offering. Moreover, regarding age, we found that most participants were not very young: 41% were aged 31 to 45 years, 20% were aged over 50 years, and 12% were aged 46 to 50 years. Yet digital learning is a modern methodology.

The SPOC allowed experiences to be shared. The participant did not need to train alone in front of his or her computer but could also be involved in social and collaborative work. In fact, Uijl et al [24] recently evaluated 4 courses from the University Medical Center Utrecht’s international Master’s Program in Epidemiology. The 71 included students benefited from extended social interactions during the SPOC. There were around 1500 interactive posts across the 4 courses, in 575 discussions, of which 43% were social discussions. Of these, 90% were initiated by students, and 94% was aimed at students. The authors of this study concluded that the SPOC had a sustainable concept and created an environment suitable for learning, thus fitting with the need for social interactions in higher education [24]. The same results have been observed in other studies [25-27], as well as in our SPOC.

In the second course offering, we improved interactions between the participants through a dedicated forum with collaborative exercises. We deliberately mixed professionals from different areas and institutions: about one-third were in private practice, one-third worked in a public hospital, and one-third worked in a private institution. The result of these interactions was further complemented by peer evaluation. All these activities contributed to the development of a social learning environment and (in large part) to the high completion rate. Indeed, most participants felt their expectations had been met (91%).

As shown in an online accreditation course, a professional practice forum improved learning outcomes through sharing expertise [28]. The SPOC seemed to be a good way to strengthen coherence and communication between the different caregivers (nurses, doctors, pharmacists, physiotherapists, etc). It became clear that digital learning improved communication and united the participants’ efforts on one subject, thus forming a link between those working in the hospital and those working in the surrounding community. In study of a MOOC on diabetes, Wewer Albrechtsen et al reported that, among 845 caregivers, the MOOC had a positive effect on their practice of 88% and extended the professional network of 48% [29].

One major positive aspect of this teaching method is its wide accessibility. As demonstrated in our SPOC, training was accessible from a participant’s computer or tablet from anywhere and at any time. We observed that 4.26% (19/446) of our participants lived outside France: they were either expatriates or foreigners who spoke French.

We analyzed the cost effectiveness of this type of education. In our study, we compared the overall cost of our SPOC with that of a traditional classroom for the same number of participants. We found that the online course was more cost effective when there were more than 950 participants. This may be for three main reasons. First, the overall cost of the SPOC was higher (because we chose a private enterprise as the service provider, outside of the university). Second, this SPOC was free of charge to participants, whereas many online teaching courses charge fees. Third, face-to-face education does not allow for the course to be offered in foreign countries (due to, for example, extra travel costs). Thus, the cost for SPOCs could be less than we have calculated. Other researchers have analyzed costs and compared them with costs of traditional education. In a randomized study, Nilsson et al [30] compared the cost effectiveness of a mobile app-guided versus a textbook-guided ultrasound course. Of the 34 participants who completed the course, there were no statistically significant differences in test performance or diagnostic accuracy between the 2 groups. Yet textbook-guided training was significantly more cost effective than mobile app-guided training [30]. Erbe et al described different methods to study common mental health disorders; they reported that blended interventions (combining the strengths of face-to-face and Internet approaches) were feasible and could be more effective [31]. More randomized clinical trials on the effectiveness and cost effectiveness of blended treatments are necessary. Recently, Tolsgaard and Cook discussed the costs and outcomes of improving educational programs according to their context. They concluded that, even if the costs and outcomes were individually very important, perceived value also must be considered in order to decide change of current educational practices [32].

Moreover, our questionnaire raised some points that need improvement. For example, participants commented on the general nature of the topics covered during the courses and would have liked more detail, for example, about the secondary effects of chemotherapy and radiotherapy. This feedback helped us improve the content and structure of the second SPOC offering. Indeed, SPOCs are constantly evolving, with the possibility that new modules can be added, and thus forums can be developed for discussion, collaborative exercises, and interactivity between participants. Our SPOC will be integrated further for medical and paramedical (nurse) educational institutions and universities in France. To evaluate the educational effectiveness of our SPOC, we plan to test retention of knowledge over time by sending an evaluation form to participants at 1 year after they have completed the SPOC.

The clarity (information, support, access, registration, and content), communication (exercises and forum), and interactivity (assessment, collaborative exercises, and feedback) in our SPOC made this a good educational method for CPD and interprofessional education. This relatively new digital learning tool is an attractive concept to integrate teaching, especially in oncology. It offers optimal propagation of information in a cost-effective way and meets the students’ expectations for training.
