The beliefs of Senegal’s physicians toward the use of telemedicine

Introduction Telemedicine is seen as a potential solution to improve access to specialist services in underserved areas, but using telemedicine depends on physicians' beliefs regarding its use. Applying the theory of planned behaviour, there are three kinds of beliefs of relevance: behavioural, normative and control beliefs. This study aimed to determine the behavioural, normative and control beliefs of Senegal's physicians regarding the use of telemedicine. Methods A qualitative descriptive study involving individual interviews with physicians was conducted between January and June 2014. It included 32 physicians working in public hospitals and 37 physicians working in district health centres. Interviews were taped, transcribed and their content coded thematically using the NVivo 10 software. Results The most significant positive behavioural belief was that telemedicine makes experts' opinions accessible despite distance; the most important negative behavioural belief was that telemedicine can lead to medical errors. The positive normative belief mentioned most was that patients approve the use of telemedicine, but the negative normative belief mentioned most was that the patients would not approve it. The prevailing positive control belief was that physicians will use telemedicine if it is easy to use and the most cited negative control belief was that physicians will not use telemedicine if they have insufficient time. Conclusion The results of this study provide a better understanding of the beliefs of Senegal's physicians regarding telemedicine, which can help in designing interventions to promote its use. Such interventions may help improve access to healthcare in rural areas.


Introduction
Physicians are unevenly distributed in Senegal; only 24% of them working in rural areas where 60% of the country's population lives [1]. This uneven distribution leads to unequal access to healthcare and consequently to health inequalities [2]. One of the leading causes of this uneven distribution of physicians is the failure to both recruit and retain them in rural areas. This failure is influenced by many factors; the best-known are contextual, economic, educational, family, individual, organizational and professional factors [3,4]. International migration also plays an important role with more than 51% of Senegalese-trained physicians work abroad [5]. During the last few decades, Senegal has adopted production and management measures to recruit and retain physicians in rural areas. Production measures include the opening of private medical schools and the provision of fellowships to students who accept to practice in rural areas [3].  [3]. To date, none of these measures has resulted in a more equitable distribution of physicians between rural and urban areas. In this context, telemedicine, the practice of medicine from a distance through information and communication technologies (ICT) [6], could be a useful means to recruit and retain physicians, and to improve access to healthcare in rural areas [4]. The potential success of telemedicine in this regard depends, in part, on physicians' beliefs regarding its use, on which little is known at present. The purpose of this study, then, was to determine Senegalese physicians' beliefs concerning the use of telemedicine drawing upon the theory of planned behavior (TPB) which distinguished between behavioural, normative and control forms. Behavioural beliefs refer to the subjective probability that behaviour will produce a given outcome.
Normative beliefs refer to the perceived behavioural expectations of important referents, including individuals or groups. Control beliefs refer to the perceived presence of factors that may facilitate or impede the performance of the behaviour [7]. This study focuses on physicians working in the public sector only, particularly those working in public hospitals and district health centres, as logistical limitations precluded inclusion of physicians working in the private sector. Existing research, suggests that with regard to behavioural beliefs, telemedicine is considered to reduce the transportation of patients, saving costs [8][9][10], while also facilitating access to continuing education, research and professional exchanges [9][10][11].
Telemedicine is seen as a means to improve the quality of health services and to reduce medical errors [9,11,12], but is also suspected to have a negative impact on data security, the physician/patient relationship and physician work overload [8,10,13]. Telemedicine is equally considered as potentially leading to medical errors, and as an inefficient means to guarantee a good income for physicians [14]. In relation to the normative beliefs, some studies suggest that nurses, physicians and patients are all likely to approve of telemedicine use, [15][16][17], although others believe that both physicians and patients may be opposed to its use [17]. With respect to control beliefs, a determining factor may be the ease of equipment use, physicians' existing familiarity with computers, and their access to handheld devices (e.g. a smartphone) and the internet [15,18]. Data security, data conservation, technical problems, a lack of training, and patient opposition to telemedicine services are all thought to negatively affect perceived control [13, [19][20][21]. Most of these studies were carried out in high-income countries. Little is known about the transferability of their findings to low-income countries such as Senegal. This article reports on the first such study exploring such beliefs amongst practicing physicians in Senegal, with potentially transferable findings to other African countries at a similar level of health system development.

Methods
Study design, participants, and sampling: to identify Senegalese physicians' beliefs about telemedicine use, we conducted a qualitative descriptive study involving individual interviews. Participants comprised physicians who practicing in public hospitals (total N = 596) and district health centres (total N = 187), based on 2013 data.
Using purposive random sampling, 40 physicians were selected from those practicing in public hospitals and 40 from those practicing in district health centres. These physicians were contacted to establish their availability, willingness to participate in the study, and consent to be interviewed and audio-recorded. Thirdy-two physicians practicing in public hospitals and 37 practicing in district health centres accepted to participate in the study.
Data collection: participants were interviewed individually in person. All interviews were audio-recorded and took place in public hospitals, district health centres, physicians' homes, hotels, restaurants, the airport, training centres and at Cheikh Anta Diop University, depending on each physician's availability and preference.
An interview guide was designed and used to facilitate the conduct of individual interviews. Physicians were asked about their positive (advantages of using telemedicine) and negative (inconvenience of using telemedicine) behavioural beliefs; positive (people who can approve their use of telemedicine) and negative (people who can disapprove their use of telemedicine) normative beliefs; and positive (facilitators of the use of telemedicine) and negative (barriers to the use of telemedicine) control beliefs. Table 1

Results
Socio-demographic and professional characteristics of participants: Table 2 shows the socio-demographic and professional characteristics of the physicians. The 32 physicians working in public hospitals were selected from 13 public hospitals spread across five administrative regions. Their average age was 44, with a range of 29 to 61. They were all specialist physicians (32) with more male (25) than female (7) participants. The 37 physicians working in district health centres were selected from 37 district health centres spread across 12 administrative regions. Their average age was 40, with a range of 33 to 53. They were more specialist physicians (24) than general practitioners (13) again with more male (35) than female (2) physicians.

Physicians' behavioural beliefs
Positive behavioural beliefs: Table 3 provides an overview of the positive behavioural beliefs and their number of mention by each group of physicians (those working in district health centres and those working in public hospitals). Physicians working in public hospitals believe that telemedicine allows them to access experts' opinions remotely, to treat their patients remotely, to train themselves continuously, to do research, to reduce their travel outside their work locations, and to save time. They also believe that telemedicine enables their patients' to avoid transportation costs and time and to better organize their patients' transfer if needed. They equally believe that telemedicine enables their health facility to save costs. Finally, they think that telemedicine can contribute to the training of other health professionals. In relation to remote treatment and exchanges with experts, one of the physicians working in public hospitals said: "Well! with telemedicine, I can provide care to patients. I can give advice. I can share my impressions on radiographic images. I can propose a strategy to treat each patient. I can do all these things" (male specialist physician working in a public hospital in Dakar). The physicians working in district health centres identified similar beliefs, for example: "As I said, (telemedicine) benefits include knowledge exchanges between health professionals and saving patients' time and money" (male general practitioner working in a district health centre outside Dakar). The only difference between hospital and district health centre responses was that in the latter locale physicians did not mention telemedicine's contribution to the training of other health professionals. Conversely, physicians in district health centres uniquely reported that the installation of telemedicine equipment (telecommunications and medicine equipment), which is essential to its use, will improve district health centre's the technical platform and hence its reputation amongst patients. Table 3 provides an overview of the negative behavioural beliefs and their number of mention by group of physicians. Specialist physicians working in public hospitals express concern over telemedicine potential to lead to medical errors, data security problem, additional costs to patients and patients' physical safety risks due to the likelihood of increased medical tests generated through telemedicine use. One physician working in a public hospital, reflecting a frequently cited concern, commented that: "The main drawback (with telemedicine) that I find is disclosure of patients' confidential medical information through communication technologies which are not totally secure" (female specialist physician working in a public hospital in Dakar). In relation to patients' physical safety, another physician working in a public hospital said: "Patients need to be protected. I mean that the prescription of various medical tests needs to be justified. People (physicians) will ask for medical tests that are not always needed and that can put patients in more danger.

Negative behavioural beliefs:
I think that this is part of telemedicine's inconvenience" (male specialist physician working in a public hospital in Dakar). Physicians working in district health centres held the same beliefs except the one about the physical safety of their patients. Conversely, physicians working in district health centres uniquely commented on how telemedicine might affect their relationship with their patients by reducing patient trust in their abilities: "Some patients think that we are supermen. They won't understand that we consult another physician (using telemedicine) to treat them. They could say that we are not skilled enough. They can become distrustful of us" (male general practitioner working in a district health centre outside Dakar).
Another concern for physicians working in district health centres was how telemedicine might prevent them from regularly visiting their families in Dakar by reducing their need to travel to Dakar for training, conference, or other practice-related reasons: "telemedicine will reduce my moves outside my area, but my family, which is in Dakar, may dislike that. My wife and my children would like that I frequently come home because I don't live with them. Here, I live alone." (male specialist physician working in a district health centre outside Dakar).

Physicians' normative beliefs
Positive normative beliefs: Table 4 Table 4  Physicians in district health centres identified similar referents apart from those associated directly with hospital administration. They also identified many of the same "positive" referents as potentially having a negative impact, including their private sector colleagues or those splitting time between both private and public, who may see telemedicine as introducing a new competitive element.

Physicians' control beliefs
Positive control beliefs: only one positive control belief was identified: the ease of use of telemedicine which refers to how easily physicians can use telemedicine equipment (Table 5). "If it is something easy in which I will not waste too much time, for example, to start the connection or to download something, I am ready to use it" (male specialist physician working in a public hospital in Dakar). Table 5

Discussion
Our results show that Senegal's physicians perceived both advantages (positive behavioural beliefs) and disadvantages (negative behavioural beliefs) of using telemedicine in their professional activities. The results are broadly consistent with those of the literature reviewed earlier, although that advantages and disadvantages were often contradictory (e.g. telemedicine has the potential to reduce medical error while also increasing medical error); this could indicate some continuing discomfort or uncertainty about telemedicine, at least across the physician population as a whole.
Further probing of these apparent contradictions would be useful in any initiative to increase telemedicine use in the country. That physicians mentioned twice as many advantages as disadvantages suggests that Senegal's physicians may have a more positive than negative attitude toward telemedicine use. The theory of planned behaviour, however, posits that a positive intention also depends on normative and control beliefs. As normative beliefs, many different individuals and groups were identified, and were thought to be supportive but, again and somewhat paradoxically, many were recognized, at the same time and by the same physician being interviewed, as being both a supporter and an opponent. These results coincide with those of researchers that found that nurses [15], physicians [15][16][17] and patients [16,17] can approve the use of telemedicine, but that physicians and patients can also disapprove it [17]. This may reflect differences amongst our physician sample (some seeing the same referent group as a positive, others as a negative, influence) but it could also attest to physicians recognizing the variability that might exist within their referent group, or in the case of patients, specific individuals, or specific patient/physician encounters. Nonetheless, the breadth of referent groups identified infers that the development of telemedicine in Senegal will require a multi-sectoral approach involving quite a large number of individuals and groups, and awareness campaigns targeting referent groups on the necessity of their support for telemedicine use by physicians.
Control beliefs refer to the factors that can encourage or prevent the use of telemedicine by physicians. The control belief regarding ease of use was considered as the only factor that would encourage telemedicine use by our participants. Several others beliefs related to complexity of the technology, training, equipment maintenance or technical difficulties were all seen as impediments to its use, consistent with findings from other studies. These results indicate that Senegal's physicians perceive more barriers than facilitators, which is likely to negatively affect their perceived behavioural control and hence use of telemedicine ( Figure 1) What is known about this topic  Regarding the difficulty to equitably distribute physicians between rural and urban areas, telemedicine is considered as a good means to improve access to physicians, particularly  Tables and figure   Table 1: interview guide for the study of physicians' beliefs Table 2: socio-demographic and professional characteristics of the physicians working in public hospitals and district health centres     Are there any individuals or groups of individuals who would disapprove of your decision to use telemedicine in your professional activities?
