Abstract
Objective
Global efforts to implement national ehealth strategies have occurred, yet specific telemedicine implementations have fallen behind. A weakness inherent within many, perhaps most, national ehealth strategies, including Botswana's – is a lack of telemedicine focus. This is despite its potential to address many current healthcare system needs. The development of a telemedicine-specific strategy, to complement the existing ehealth strategy, has been proposed. This paper reports on an emulated process to determine prioritised health needs, identify broad solutions, consider ehealth and then telemedicine solutions, and prioritise these as insight for telemedicine-specific strategy development.
Methods
The eHealth Strategy Development Framework (eHSDF) was adopted and steps 5–7 were emulated. Key informants participated in telephone-based semi-structured interviews in November 2020, using a key informant interview guide. Participants were asked specific questions related to national health needs, proposed solutions, and prioritisation. The interviews were recorded and transcribed for analysis.
Results
Eleven key informants identified the top five perceived health issues as human resource shortages, congestion and overcrowding, prevalence of diseases, poor referral system, and lack of diagnostic and case management skills. Solutions were proposed, some of which included: Telehealth (including telemedicine), health informatics, and elearning. Telemedicine solutions included: a health professional help desk, teleconsultations, and apps for specialist referral. eLearning solutions were training, mentoring, and continuing professional development.
Conclusion
A telemedicine-specific strategy, addressing the identified health issues and aligned to the existing national ehealth strategy, would provide the required focus to enable the development and deployment of telemedicine activities in the country.
Introduction
eHealth (the use of information and communication technologies (ICT) for health 1 ) is broadly seen as a facilitator of health, and the importance of an ehealth strategy has been emphasised as a prerequisite for national and even local ehealth implementation.2–4 However, many countries, perhaps more so developing countries, still have discrete and uncoordinated ehealth activities, experience policy barriers, suffer from ‘pilotitis’, or have experienced failed implementations.5–7 Botswana has encountered each, but has also been proactive in strategy development. Three components of ehealth exist or have existed in the country; health informatics, telemedicine and elearning. The health informatics implementations are incomplete and only a few of the available modules for an Integrated Patient Management System (IPMS) have been installed. mHealth initiatives in telemedicine and elearning (mHealth being defined as ‘the use of mobile wireless technologies for public health’ 8 have been limited and funder dependent, and most have stopped, 9 although future growth is expected. 10
Botswana is a land-locked country located in southern Africa. It has a relatively young population of ∼2.35 million (2020), median age of 24 years, who are concentrated in and around the two major cities Gaborone and Francistown with an overall population density of only 4 people per km2.11,12 The country provides universal healthcare via a public healthcare system, delivered using a decentralised model focussed on primary care through a network of health facilities (hospitals, clinics, health posts and mobile stops) in 27 health districts (some private healthcare is also available). 13 Similar to many countries in sub-Saharan Africa, the healthcare workforce is limited: Physicians and nurses/midwives per 10,000 population were 3.4 and 28.4 in 2006, 12 and 4.0 and 42 (rural – 3 and 26; urban 9 and 77) in 2014; 14 physicians were 2.9 in 2018. 15 The WHO has identified countries with fewer than 10 doctors and 40 nurses/midwives per 10,000 as having ‘insufficient healthcare professionals’, 16 and projected that in the African region the needs-based shortage of health workers will worsen by 45% between 2013 and 2030. 17 Botswana appears well connected, with mobile cellular telephone subscriptions at 3.8 million and Internet subscriptions at 2.1 million in 2020. 18 Distribution and ownership of mobile phones (including smartphones) in Botswana is uncertain, but it is important to note that the above numbers represent active mobile SIM cards for all mobile devices, not unique cellphone owners.
The country's national ehealth strategy has developed over time. In 2004, Botswana's ehealth policy was incorporated as an addendum to the country's national ICT Policy. In 2015, Botswana developed a draft ehealth strategy premised on the WHO/ITU eHealth Strategy Toolkit, 19 which was approved for implementation in March 2020. However, this strategy lacks a clear focus on telemedicine which could address some of the current health system's shortcomings and deficiencies in healthcare provision and delivery. This shortcoming has been identified resulting in a recommendation for a related telemedicine-specific strategy aligned with the existing National eHealth Strategy. 9 Telemedicine is described as ‘The delivery of health care services, where distance is a critical factor, by all health care professionals using information and communication technologies for the exchange of valid information for diagnosis, treatment and prevention of disease and injuries, research and evaluation, and for the continuing education of health care providers, all in the interests of advancing the health of individuals and their communities’. 20
A scan of the grey literature by the authors found inconsistent strategy-related documentation across sub-Saharan African countries (health strategies, ICT strategies, ehealth strategies), but no telemedicine-specific strategy. Many documents were stale-dated. Even within the available English language ehealth strategy documents reviewed, telemedicine was often mentioned only in passing or not at all. To the authors’ knowledge, there is no approved telemedicine-specific strategy for any country in the sub-Saharan Africa region.
While there is an absence of published national telemedicine strategies for comparison and guidance, as well as limited telemedicine strategy development guidance,21,22 the literature does provide guidance on ehealth strategy development with perhaps four practical and detailed documents describing generic ehealth strategy development.4,23–25 Of these, the ‘eHealth Strategy Development Framework’ (eHSDF) 4 was selected as the most suitable tool due to its theory-driven, evidence-based, and clear stepwise approach to strategy development, capable of being applied in local, regional, or national levels. The spirit and intent of the eHSDF are to develop an overall ehealth strategy that identifies specific ehealth solutions (telehealth, health informatics, elearning and ecommerce) for the specific evidence-based health needs of any particular jurisdiction. Because telemedicine is a subset of ehealth, the eHSDF should allow for the development of a telemedicine-specific strategy.
In the absence of the ability to fully implement the eHSDF process nationally, as is intended, it was emulated as an academic exercise. Seven fundamental principles serve to provide a foundation for the eHSDF, with the process having nine steps, of which seven are described in detail. 4 These are summarised in Table 1. The eHSDF has three basic constituent elements. The first series of steps (Steps 1 to 4) focus on identifying the specific health needs of the jurisdiction; the second series of steps (Steps 5 to 7) focus on identifying solutions and then specific ehealth solutions to the identified needs; and the final steps (Steps 8 to 9) collate the findings into a cohesive strategy (Step 8) and policy direction (Step 9). Thereafter further undertakings must occur, such as the development of the required enterprise architecture, as well as distinct business, readiness assessment, implementation, change management, operational and evaluation plans as required. Steps 1 and 2 and part of Step 4 have been previously reported.9,26 Step 3 (Differential Diagnosis) relates to differing needs of distinct locales or populations within a jurisdiction, and given the focus on national strategy, this step was not emulated.
As its starting point, this study used findings from prior research that had surveyed 142 healthcare workers and patients, and identified 14 health issues of concern for Botswana. 26 The paper reports on the emulation of a component of Step 4, and Steps 5 through 7 of the eHSDF which focus on identifying overarching solutions and then specific ehealth solutions to the health needs previously identified. The study lays the groundwork for the final development of a telemedicine-specific strategy to align with, complement, and strengthen Botswana's formally adopted National eHealth Strategy.
Methods
Key informant selection and recruitment
A non-probability sampling approach was adopted. Key informants (KIs) were identified and were selected on the basis of being experts, knowledgeable and involved in ehealth activities in Botswana. Sixteen KIs were approached; five did not respond. The remaining 11 (69%) were recruited; seven healthcare professionals and four ehealth experts (Table 2). According to Malterud et al., 27 an adequate sample size for interview studies requires sufficient ‘information power’: ‘Information power indicates that the more information the sample holds, relevant for the actual study, the lower number of participants is needed’. 27 Consideration of the five factors impacting ‘information power’ indicated eleven participants of diverse role and location (Table 2) was satisfactory. Healthcare professionals were participants of a prior survey who had consented to further contact. They were purposively selected as follows: three from hospitals and four from clinics (Table 2). Four ehealth experts were also purposively selected from academia (public–private sector health–related) and government (Table 2). They participated in a preliminary needs assessment and subsequent interviews.
Key informant characteristics.
KI interview process
KIs were e-mailed an information package, consent form, and a list of 14 previously identified health issues in Botswana. These health issues were identified in prior research based upon survey responses from 142 healthcare workers and patients. 26 Each KI was requested to review the information package and to read and sign the consent form. Once consented, their tasks were to: select the top five health issues ranking them according to their perceived priority; return the signed consent form, their list of selected and prioritised health issues; and indicate when they should be contacted for the Key Informant Interview (KII). Those without printing or scanning facilities could complete the process online (Google Forms). Upon receipt, a telephone-based KII was scheduled (in accordance with COVID-19 protocols and procedures prevailing at the time).
A KII guide was developed by the authors to conduct the semi-structured interviews in a consistent manner (Supplementary File 1). Participants consented to the interviews being recorded.
These KIIs were used to emulate Steps 4 to 7 in the eHSDF process as follows.
Step 4
Termed ‘Preliminary Prioritisation’ this step is intended to determine the priority health needs (and their associated characteristics). 4 Prior research had listed 14 perceived health issues. 26 Using this list, and prior to their interviews, each KI identified and prioritised their top 5 perceived health issues to be resolved within Botswana, listing them in order of priority. These results were collated and analysed using the Excel ranking function to create a ranked list of the health needs in Botswana requiring resolution The top five items from this list were subsequently presented to each KI during their interview.
Step 5
Termed ‘Identifying Solutions’ this step requires that
Step 6
Termed ‘Considering eHealth Solutions’ the eHSDF gives focus to the top 20% of identified health issues, and technologically appropriate, culturally sensitive, and financially feasible ehealth options are identified for each, whether telehealth, health informatics, elearning, or ecommerce related. 4 Having identified optimal approaches to address each identified health issue (Step 5), KIs were asked to identify which of these approaches might involve the use of ehealth? Informants were reminded that an ‘eHealth Solution’ could include health informatics (e.g. erecords; esurveillance), telehealth (teleconsultation; health-related apps), elearning (education of healthcare professionals and/or patients), or ecommerce (health professional reimbursement), or a combination. Participants were encouraged to brainstorm, focusing on concepts and not details.
Step 7
Termed ‘Secondary Prioritisation’ this step identifies priority ehealth solutions, based upon differentiation between potential options that would be considered

Results
A ranked list of health needs in Botswana requiring resolution, created collectively by KIs prior to their interview, was created (Table 3).

Analysis of KII transcripts from Step 5 identified nine themes. These were: health human resource (HHR) shortages, congestion and overcrowding, prevalence of disease, poor referral system, lack of diagnostic and case management skills, medication shortages, reporting laboratory test results, transport shortages, and lack of medical equipment. The most prevalent related to HHR shortages. Results for each are described below.
For ‘HHR shortages’, KIs noted the need for government intervention to establish policy and provide financing that addressed the pervasive shortages. ‘
In relation to ‘congestion and overcrowding at healthcare facilities’ the majority of KIs (
To directly address the ‘prevalence of diseases’ nearly all KIs (
Regarding the ‘poor referral system’, most KIs (
Almost two-thirds of the participants (
Overall, KIs believed such approaches would result in better patient outcomes and improve the quality of future service delivery as experience in the field is gained. Mandatory continuing professional development (CPD) for physicians, similar to nurses, was noted, as was the inclusion of evidence-based medicine and clinical practice guidelines by training institutes for CPD. KI-01 was quite vociferous in this regard: ‘
Participants noted the problem of ‘medication shortages’ to be associated with poor resource management rather than financing (procuring incorrect medications; allocating nearly expired medications; provision of incorrect alternatives). KIs indicated these required policy changes not only the use of medication management/inventory management systems with collaboration and effective communications between healthcare facilities and central medical stores. One KI implied redistribution of medications through ‘
To permit prompt reporting of ‘laboratory test results’ the introduction of laboratory information systems, fully automated and integrated to SMS platforms, was the only recommended solution, and this by only one KI. Although a laboratory module exists in the IPMS, installed in all government hospitals and some clinics, most participants indicated that IPMS (the most widespread ehealth solution in Botswana) was a failing system. Generally, clinicians rarely use it, being perceived as not user friendly and unavailable when needed. Responses varied, but all indicated issues with the IPMS: ‘
As a resolution to ‘transport shortages’ some KIs (
Subsequently, as part of Step 6, informants were asked to refocus and identify possible ehealth solutions (telehealth, health informatics, elearning or ecommerce) to address the above-perceived health issues and potential solutions. There was a clear belief that ehealth could help in diverse ways: ‘

Step 7 (Secondary Prioritisation) identified three dominant ehealth solutions that were endorsed by key informants: telehealth, e.g. adoption of telemedicine specialties and surveillance tools; health informatics, e.g. electronic medical records and associated software tools such as decision support software; and eLearning, e.g. mandatory CPD for clinicians. Policy changes would facilitate such initiatives.
Discussion
Building on prior research that identified health issues of concern to Botswana, 26 and through emulating several steps of the eHSDF, this study has collected evidence regarding potential ehealth solutions to these issues supporting the need for the development of an effective telemedicine-specific strategy. KI interaction and interviews identified priority health issues, proposed solutions to each identified health issue, identified which proposed solutions could benefit from ehealth applications, and ultimately distinguished priority ehealth solutions. Three dominant ehealth categories were endorsed by key informants: telehealth, health informatics, and elearning. Possible telemedicine solutions could address several of the identified health needs for Botswana identified in Table 3. HHR shortages (including ‘ehealth’ HHR shortages) were found to be central to most of the identified issues. This provides a clear area of focus, since tackling this problem would also positively impact related but peripheral problems. For example, CPD and videoconsultation could enhance local skills and clinical abilities, improving patient outcomes, healthcare worker satisfaction, and easing upstream (referral facility) overcrowding. Other identified challenges included the prevalence of diseases, poor referral system, lack of diagnostic and case management skills and medication shortages.
For the process in Botswana, the following health needs were identified: a critical shortage of healthcare workers, the prevalence of diseases, poor referral system, congestion and overcrowding at health facilities, lack of diagnosis and case management skills of healthcare workers, as well as medication shortages. These findings are not unexpected, as they reflect the reality of many developing countries.30–32 Significantly, telemedicine (as defined) can aid in addressing some of these issues at the practice and process levels and can be enabled at the policy level. Indeed, creating a conducive setting for some ehealth solutions may require policy changes to support investment and aid integration into healthcare systems, recognising the economic, social, and organisational factors that affect sustainable implementation.7,33
The COVID pandemic remains unresolved. Many examples have been described of the use of ehealth to address and resolve aspects of the provision of medical services during the COVID-19 pandemic and it is speculated that its use will be ongoing post-pandemic.34–37 However, of note is that despite the KIIs taking place early in the COVID-19 pandemic (prior to a clear understanding of its severity and longevity) it was not raised as a priority healthcare issue in any KII, although noted by two KIs. The key issue identified was the shortage and maldistribution (urbanisation) of HHR impacting healthcare delivery, particularly in rural areas, which has been described in five categories: provider shortages, maldistribution, quality deficiencies, access limitations and the inefficient utilisation of health care services. 38 Whilst telemedicine cannot immediately increase the number of qualified healthcare workers, it can impact access to and effectiveness of the existing workforce. Thus mHealth, one component of telehealth, has been successfully used to address many purposes including chronic diseases, infectious diseases, health monitoring and surveillance, behaviour change, and mental health.39–42 Similarly, telemedicine can ease referrals 39 and improve the referral process, 43 having knock-on effects that decrease congestion at referral centres. 44 In addition, telemedicine can improve local clinical care and skill levels through consultation and formal (online elearning programmes) and informal (experiential learning) education, enhancing diagnostic and case management skills.45,46 The issue of medication shortages often has more to do with maldistribution and poor supply chain management leading to wastage, 47 and ehealth solutions may crossover between health informatics and telemedicine through national and facility focused software programs to monitor the process. 48
Despite the above, telemedicine can also impact the number of qualified healthcare workers. Indeed, the use of Technology Enabled and Enhanced Training (TEET) 49 has had to be rapidly employed and expanded due to the COVID-19 pandemic.
The development of a complementary approach distinct from an existing ehealth strategy is not entirely new, with Ethiopia and South Africa having developed parallel mHealth strategies to supplement their existing ehealth strategies.50,51 Although it is generally believed that most sub-Saharan African countries have ehealth strategies, the authors’ knowledge suggests the contrary. Many are not true national ehealth strategies (lacking the orderly, systematic, and progressively derived detail developed through following the eHSDF), but instead are often national ‘ICT’ strategies, or national ehealth ‘policies', ‘roadmaps’, or ‘frameworks’. In the absence of widely accepted definitions in the context of ehealth, these can be characterised as: statements of a desired course of action to adopt ehealth (policy), more perfunctory descriptions of a plan to embark on the widespread use of ehealth (roadmaps), or basic ideas for a structure to support ehealth use (frameworks). More importantly, many such documents are often not current, having lapsed, and not been revised, updated, or re-instated. No sub-Saharan African country has a telemedicine-specific strategy, and other countries have no evidence of any form of ehealth or telemedicine-specific strategy documents. This may be an indication that several countries could be struggling to use the available ehealth strategy development guidance. For example, Bhaskar et al. 52 noted the need for ‘Increased strategization’ for development in ‘countries with limited access to current telehealth’. These authors concluded that ‘government support of telemedicine partnerships are required to set the groundwork in many countries’.
There is a belief that telemedicine could positively impact health delivery system performance in a developing country, when deployed in a strategic way. It was proposed that a telemedicine-specific strategy for Botswana, premised on a sound evidence base, be developed to enhance the country's current ehealth strategy document. 26 Therefore, this current study adopted a novel stepwise approach to enhance the development and deployment of ehealth services in Botswana and elsewhere by focusing on telemedicine.
Limitations
The absence of the ability to fully implement the eHSDF process nationally, as is intended, led to the emulation of the process as an academic exercise. While of value, this experience has confirmed the need for a national and more granular approach. It is recommended that governments lead and fully implement the eHSDF process nationally. Performing an emulation with larger numbers of KIs from geographically dispersed locations nationally may prove satisfactory as a preliminary step.
Conclusion
This study has provided the additional insight needed to develop an evidence-based telemedicine-specific strategy, complementary to Botswana's existing national ehealth strategy, enhancing its ability to address identified health needs. Despite limitations, the emulation approach described could be adopted and adapted by other developing countries to swiftly and inexpensively identify their own national health issues and determine which are amenable to telemedicine interventions.
