Benefits and Challenges of Using Virtual Primary Care During the COVID-19 Pandemic: From Key Lessons to a Framework for Implementation

Background: With the onset of COVID-19, general practitioners (GPs) and patients worldwide swiftly transitioned from face-to-face to digital remote consultations. There is a need to evaluate how this global shift has impacted patient care, healthcare providers, patient and carer experience, and health systems. Objective: We explored GPs' perspectives on the main benefits and challenges of using digital remote care. Methods: GPs across 20 countries completed an online questionnaire between June - September 2020. GPs' perceptions on main barriers and challenges were explored using free-text questions. Thematic analysis was used to analyse the data. Results: 1,605 respondents participated in our survey. The benefits identified included reducing COVID-19 transmission risks, guaranteeing access and continuity of care, improved efficiency, faster access to care, improved convenience and communication with patients, greater work flexibility for providers, and hastening the digital transformation of primary care and the accompanying legal frameworks. Main challenges included patient's preference for face-to-face consultations, digital exclusion, lack of physical examinations, clinical uncertainty, delays in diagnosis and treatment, overuse and misuse of digital remote care, and unsuitability for certain types of consultations. Other challenges include the lack of formal guidance, higher workloads, remuneration issues, organisational culture, technical difficulties, implementation and financial issues, and regulatory weaknesses. Conclusion: At the frontline of care delivery, GPs can provide important insights on what worked well, why, and how. Lessons learned during the emergency phase can be used to inform the stable adoption of virtual care solutions, and co-design processes and platforms that are technologically robust, secure, and supported by a strategic long-term plan.


Introduction
For decades, there have been many initiatives to implement virtual care into healthcare systems.In the US, Kaiser Permanente offers secure email communication and routine telephone and video consultations [1].In the UK, the use of telephone consultations is commonplace [2].Many other healthcare systems worldwide have advocated similarly for a virtual approach [3][4][5][6][7][8][9].
The use of virtual care, either via telephone, video, or online technologies, has potential implications on the six domains of quality of care: timeliness, efficiency, patient-centredness, effectiveness, safety, and equity [10].Virtual consultations can reduce delays in the diagnosis and treatment, thus improving timeliness [11].They can also facilitate access for patients living in isolated areas, and reduce inequities in care delivery [12][13][14].Remote care can improve primary care efficiency by acting as a gatekeeper by remotely triaging patients, identifying those who require urgent face-to-face care from those who can be managed virtually [15][16][17].While some studies have suggested that virtual care can improve efficiency and generate time savings [18,19], others did not find a statistically significant reduction [20].Remote care can support the delivery of more patient-centred care and the development of self-management skills [21,22].Virtual care can be effective in the management of chronic conditions, including chronic obstructive pulmonary disease, heart failure, and diabetes mellitus [23].Studies have also suggested improvements on patient safety and a potential reduction in hospital admissions [20,23].However, despite the promised benefits, virtual care has been integrated slowly into primary care.A wide range of obstacles have limited widespread adoption, including cultural, regulatory and policy, industrial and technical, knowledge, financial, and market-related barriers [24].
With the onset of COVID-19, the primary care landscape was radically transformed [25,26].Many countries have released national guidance encouraging the use of virtual triage and consultation systems [26].In a few weeks, General Practitioners (GPs) and patients worldwide transitioned from face-to-face consultations to virtual care [27].Whilst previous evidence surrounding the use of remote care in general practice came from relatively small and local clinical trials, this pandemic forced patients, healthcare providers, and healthcare systems to embrace virtual consultations as the primary route to access care.Thus, this presents us with a unique opportunity to learn more from this global real-life experiment, identify the main challenges and benefits experienced, and incorporate these lessons into the future of virtual primary care [28].
As healthcare providers on the frontline of care delivery, GPs are excellently placed to identify the benefits and challenges of using digital tools for remote care.This study aimed to explore GPs' perspectives on the main benefits and challenges of using virtual care, mapping them against the main domains of quality of care whenever possible.As a secondary aim, we sought to summarise findings as a framework of recommendations for the implementation of virtual care delivery in primary care settings.

Methods
The study used an online questionnaire survey of GPs in twenty countries.Recruitment took place between June -September 2020.

Study population
The inSIGHT Research Group is a worldwide collaboration of primary care researchers exploring the impact of the COVID-19 pandemic on the adoption of virtual primary care.The research group is spread across 20 countries (Australia, Brazil, Canada, Chile, Colombia, Croatia, Finland, France, Germany, Ireland, Israel, Italy, Poland, Portugal, Slovenia, Spain, Sweden, Turkey, United Kingdom, United States).Participants were eligible for the survey if they were GPs working in these countries between March and September 2020.Sampling Each local lead sent an email invitation to GPs in their country and shared the link to the survey in social media channels (e.g., LinkedIn, Twitter, Facebook).Local leads who had difficulty achieving the minimum number required used snowballing to increase the number of responses.Snowballing is a recognised technique for recruiting hard-to-reach populations in health studies [29][30][31].

Description of the questionnaire
The questionnaire included 30 items assessing GPs' perspectives on the adoption and experience of virtual care solutions during the COVID-19 outbreak.Participants' characteristics were collected, including age, gender, country, practice setting, number of years of experience as GP, and involvement in teaching activities.GPs' perceptions on the main benefits and challenges of using virtual care were assessed using free-text questions.

Data analysis
Participants' characteristics were analysed using descriptive statistics.Two independent researchers systematically reviewed the transcripts using the framework analysis method, which includes five main stages: familiarisation, identifying a thematic framework, indexing, charting, and mapping and interpretation [19].At every stage of the data analysis process, the coding framework was kept deductive and inductive, allowing the inclusion of emergent themes.The coding tree was shared between all researchers for iterative refinement until consensus was reached.Resultant themes, subthemes, and the relationships between them, will be visualised using the Miro online whiteboard application [32].As participants did not provide consent for further contact, it was not possible to ask them to provide feedback on the findings.The Consolidated Criteria for Reporting Qualitative Studies checklist was used to ensure the study meets the recommended standards of qualitative data reporting.

Ethics
Overall ethical approval for this project was granted by the Imperial College Research Ethics Committee (ICREC) (Reference 20IC5956).This is a dedicated ethics oversight body at Imperial College London for all health-related research involving human participants.In addition, whenever necessary, local ethical approval and relevant permissions in the respective participating countries were also obtained.

Participants' characteristics
1,605 participants participated in the questionnaire.Most respondents (79.3%) were aged 30-59 years, and 60.9% were female (n=978).Most of the participants have been working as GPs for a minimum of 5 years (79.1%, n=1,329) and reported being involved in teaching activities (63.7%, n=1,023).More than half (62.5%) worked in an urban setting (n=1,004).A full description of the participants, including a breakdown per country, is shown in Table 1.• "Allow qualified triage by doctors, giving access to face-to-face to the patients that do need it (ID 126, Portugal) • "By doing a prior telephone screening, face-to-face assistance and follow-up could be better prioritized.
Before, almost all patients requested a face-to-face appointment as soon as possible without any prioritization or filtering criteria.That was a great improvement."((ID401, Spain) • "Help filter patients and problems, so that only cases that are critical and need a prompt resolution make it to the healthcare centres" (ID 274, Chile) • "Optimise health resources, especially human resources" (ID 870, Chile) • 'Optimisation of resources to answer the healthcare needs of the population' (ID 327, Portugal) • 'We have learned that many issues can be taken care of without a face-to-face consultation.This seems to be efficient for both the doctors and the patients' (ID 10, Finland) Benefits for healthcare professionals Some respondents identified the ability to work remotely as a major benefit, as well as having more control over their schedule.Benefits for healthcare systems Many respondents underscored the use of virtual care gained during the COVID-19 pandemic has been a major factor hastening the digital transformation (i.e., increasing awareness and trust, improving digital skills of both patients and providers, and upgrading technical capacity).Some participants mention the quick deployment of new digital opportunities (e.g., access to e-referrals, e-prescriptions, and electronic processing of fit-to-work certificates).Other benefits included changes in legal and regulatory frameworks, particularly in what concerns the legal context and remunerations of remote care tasks.

Quality of care
Participants were concerned that remote care can negatively impact some aspects of patient-centredness, including patient preferences and the patient-doctor relationship.In fact, one of the identified detractors to the use of virtual care was patients' preference for traditional face-to-face consultations.GPs also reported that it was often difficult to gauge a patient's body language and emotions through digital video/audio channels, thus impairing their ability to build rapport, express empathy, and provide more holistic care to their patients.GPs acknowledge this to have a potential negative impact on patients' wellbeing, since physically attending appointments was an opportunity for social interaction for socially isolated individuals.For clinicians, remote consultations posed additional challenges for patient communication, particularly in emotionally difficult situations, or when there was a need to ensure that their medical advice was properly understood.Participants expressed concerns regarding a negative impact on equity, particularly regarding the digital exclusion of vulnerable patients.They noted that many patients lack access to reliable internet service, and computers or smartphones to conduct video consultations.Even in circumstances where the hardware is present, some patients may lack the digital literacy and skills needed to independently set up and use relevant digital software.The most prominent safety challenge was the inability to perform clinical examinations and assess physical signs to inform clinical decision-making.While some of these issues could be mitigated through careful history taking and patient self-reporting (e.g., photographs of visible lesions and remote monitoring devices, such as blood pressure monitors, glucometers, oximeters), GPs mention that few patients had the necessary devices, and if they had, would often struggle to use them and report the results back.Dealing with uncertainty, a recognised challenge in primary care, seems to be aggravated by these factors and contribute to an increased fear of misdiagnosis and inappropriate clinical management.GPs openly expressing concerns that digital remote care could delay diagnosis and treatment.Respondents reported that these delays could be caused by patients' reluctance to use virtual care, lack of access and digital skills to use these tools, and communication challenges (i.e., to effectively convey non-verbal clinical information).GPs also emphasised some potential threats to the efficiency of care delivery.While some patients expressed hesitancy to use virtual care, others were overly enthusiastic about having a more direct line of communication with their healthcare provider, often resulting in misuse and overuse.This increase in patient demand translated into an increase in GPs' workload.Finally, a few quotes highlighted that virtual care may not be an effective solution for certain types of consultations.

Textbox 2. Main challenges: thematic analysis of the participants' narratives (Table is author's original work) THEME 1: CHALLENGED FOR QUALITY OF CARE Subtheme 1.1. Challenges for patient-centredness
• "Patient preference for face to face due to issues such as poor hearing on devices and patients not having ability to use technology."(ID 1561, Australia) • "Patients and doctors prefer face to face, many patients pay in Ireland, online isn't acceptable [to them]" (ID 1019, Ireland) • "Patients are accustomed to meet in GP clinics to talk with one another, especially older patients, lonely, they are waiting for meetings with doctors frequently too.Some have problems with electronic devices."(ID 556, Poland) • "Lack of human contact, facial and body language.Difficult to show emotions and compassion.I used to close my eyes and imagine the patient on the other side of my table.I expend more time searching the suitable words to overcome the lack of body language" (ID 62, Portugal) • "Difficulty to build rapport with patients who you don't already knowless trust of HCP" (ID 1033, UK&NI) • "Harder for people who are socially isolated, coming to the clinic was an important human interaction, form of meeting other patients, the extended team etc." (ID 630, Canada)

Subtheme 1.2. Challenges for equity, and digital exclusion
• "Some elderly (the ones with the biggest need) have problems using a telephone, let alone a computer…" (ID 1518, Sweden) • "Unfortunately, a lot of elderly patients (...) do not know how to use digital technology (email, messenger, etc) and in my opinion were deprived during the pandemic."(ID 1075, Croatia) • "[an unintended consequence was] Neglecting the less technology-oriented patients, which are also the most vulnerable ones -the elderly, the underprivileged, the immigrants etc, and in fact giving preference to the younger healthier patients, thereby deepening health inequality" (ID 254, Israel)

Subtheme 1.3. Challenges for safety
• "[It is] much harder to make decisions on the phone without examining the patient.Often patients refused to come in for appointments and didn't understand the lack of ability to assess a certain presenting complaint over the phone (e.g., abdominal pain)."(ID 1598, Australia) • "Not all necessary information concerning a patient's condition can be transmitted digitally/by phone and this causes a risk of not noticing a critical symptom/change in a patient's condition" (ID 8, Finland) • "I found that I made more mistakes when making the initial diagnosis over email / our app / phone.If there is only a one-way written communication, then it is more easy to get seduced by the patient's view and not valorise objective facts, as we would in a face-to-face consultation."(ID 1320, Croatia)

Subtheme 1.4. Challenges for timeliness
• "[A potential challenge was] not detecting patients with for instance atrial flutter because not seeing and examining them.More patients with symptoms of serious diseases are reluctant to seek care.Some are probably missed and come when the disease has progressed.I tried to be aware of this and arrange secure ways to investigate the patients."(ID 317, Sweden)

Subtheme 1.5. Challenges for effectiveness
• "Telephone consultations instead of face-to-face are less effective in many cases.It works fine for minor problems" (ID 440, Sweden) • "Harder to check up on chronic diseases patients (prescribing medications without physical examination), easier to miss potentially dangerous symptoms, harder to counsel patients in psychological distress (video calls are not common)" (ID 499, Poland) • "Online tools that don't work as well as they should (for example don't provide all the necessary information for a professional or lead to another face-to-face consultation anyway)" (ID 18, Finland)

Subtheme 3.2. Technical challenges
• "There is no resources (computers, telephones) for all health workers, therefore not everyone can work through digital techs and personal resources need to be used such as personal phones" (ID 274, Chile) • "EHR and network problems -overloaded, not prepared for massive digital use of systems, working very slowly.Still waiting for the solution (new server, better internet connection, etc)" (ID 55, Portugal) • "Lack of efficient digital equipment and software able to communicate with each other, because up to now it means opening many windows over and over again" (ID 199, Chile) • "No integration between systems and some of them do the same thing instead of complementing each other" (ID7, Portugal)

Subtheme 3.3. Implementation issues
• "The technologies were fine, but my health system did a terrible job implementing the changes.They were slow to find video services.They changed the type of video service three times."(ID 566, USA)

Subtheme 3.4. Financial issues
• "They furloughed so many staff personnel that physicians were expected to do digital appts with no staff support.There was no staff to answer phones except two days a week for two weeks.It was a mess."(ID 566, USA) • "Public organizations inability to see investments -only costs.Conservative culture within the organization."(ID 1414, Sweden) • "Lack of financial investment from governments in such technologies; Patients emotional need to get in touch with medical/other health care workers staff; Specially in Brazil, it is possible that our Medical Council pressure up against telemedicine consultations because it is an issue that before the COVID19 pandemic situation they have never been sympathetic with."(ID 65, Brazil) • "Short-sightedness of managers, Unequal distribution of resources, inbred inertia of large systems which resist change" (ID 11, Israel)

Subtheme 3.5. Legal and regulatory weaknesses
• "Current legislation limits teleconsultations" (ID 860, Chile) • "Regulatory barriers across state and geographic lines -overly strict (...) regulations -prevent right care in right venue direction" (ID 1378, USA) • "In my opinion, the main problem lies in the fact that, according to the Italian code of medical ethics, the medical examination can only take place in presence.This limit has significant repercussions on the lawfulness of the prescription and certification carried out during a video consultation."(ID 175, Italy)

Healthcare providers
The lack of formal training, guidance, and inadequate technical support were notable challenges.During the abrupt shift to virtual care, GPs reportedly had to set up, learn how to use, and troubleshoot new systems.These efforts were seldom well-organised or coordinated and often resulted in considerable transitional difficulties.Another major drawback was the higher workload and burnout.Some participants reported that they found virtual consultations to be more taxing and time-consuming to perform, which was often burdened with increased administrative tasks.As described above, the frequency and ease with which GPs could be contacted by patients often blurred the boundaries between their work and personal lives, further contributing to an increased workload.The increase in the number of patients observed daily has also resulted in less engagement with individual patients and decreased overall work satisfaction.GPs also reported inadequate remuneration as a considerable barrier to the continued use of virtual care.Whilst payment structures differed across countries, our respondents expressed that payment for remote consultation which is commensurate to in-person consultations, is critical to incentivising greater acceptance and mainstream use.As many of the remote consultation payment schemes were introduced during the initial months of COVID-19 pandemic as emergency measures, some GPs were doubtful that these efforts would be sustained over time.

Health systems
Participants mentioned organisational culture as an impediment against using virtual care.Overcoming substantial institutional inertia, the lack of pre-existing teleworking culture, the urgency to shift from familiar systems to completely new ones, and challenging the prevailing mentality of 'this was always how things were done', were commonly reported organisational barriers.Participants also reported technical issues with the digital systems used, including inadequate equipment and infrastructure, and poor systems interoperability.In particular, the lack of interoperability between several digital systems, such as appointment schedulers, electronic health records, electronic prescriptions, and epidemiological surveillance systems, was perceived as a major challenge.GPs also described implementation issues related to finances, including a general lack of investment and, more specifically, lack of funding allocated to human resources and supporting the costs of systems set-up and maintenance.Respondents noted that virtual care delivery did not appear to be in the list of priorities of many healthcare systems or policymakers.Finally, GPs identified a range of legal and regulatory weaknesses, highlighting that existing legislation is no longer fit for purpose, nor meets the evolving needs resultant from the pandemic.

Summary of key findings
Benefits for quality of care were identified for the six dimensions of quality of care, including safety (reduction of exposure risks for COVID-19 transmission); effectiveness and equity (ensuring access and continuity of care to those who need it, including those who had previously limitations to access face-toface care); efficiency (remote triage), improved timeliness and patient-centredness (convenience, communication, and patient empowerment).Benefits for healthcare providers included a greater work flexibility and more control over schedule.Benefits for healthcare systems included a transformative effect, hastening the digital transformation (increasing awareness, trust, adoption, skills, and technical capacity) and driving changes in legal and regulatory frameworks.Important challenges have also been noted for six domain of quality of care, including patient-centredness (patients' preference for face-to-face care, potential negative impact on communication), equity (lack of equipment, internet access and digital skills of some patient groups), safety (clinical uncertainty and potentially inappropriate decision making), timeliness (delays in diagnosis and treatment), effectiveness (unsuitability for certain consultations) and efficiency (overuse and misuse).Challenges specific for healthcare providers included the lack of guidance and support, higher workload, and remuneration issues.From the health systems' perspective, the long-established organisational culture, technological challenges, implementation and financial issues, and lack of accompanying supportive policies and regulatory legislation, were challenges identified by participants.

Strengths and limitations
This is the first international study to explore GPs' perceptions on the main benefits and challenges of using virtual consultations in primary care.Participants took part from 20 countries worldwide, with diverse health care systems and levels of healthcare spending.The sample size was large, with participants varying in age, clinical experience, and type of primary care setting (urban, rural, or mixed).This study employed a methodologically rigorous approach, leveraging qualitative methods to capture rich, descriptive data on individual perceptions, attitudes, and behaviours [33,34], performed according to the Consolidated Criteria for Reporting Qualitative Studies criteria [35].Finally, the main benefits and challenges were mapped against a widely recognised framework of Quality of Care [10], whenever possible.Finally, a set of recommendations was developed based on the main findings, to support providers and healthcare organisations translate the lessons learned into practice improvements.
The results must be interpreted considering some limitations.Our findings are also impacted by common limitations of survey research, including self-reported answers and self-selection sampling methods.Only GPs were included in this study; future research should focus on the inclusion of other healthcare professionals, and especially patients.The themes identified as part of this analysis may not be equally relevant for each individual country.Further qualitative content analysis could provide novel insights on their relative importance for individual countries.
Finally, virtual care is a broad concept and future research must explore specific nuances of the various types of technology available (i.e., telephone, video, chat), both in what concerns perceived benefits and challenges of implementation, and patient preferences.

Comparison with previous literature
Remote primary care is widely recognised as an promising solution to ensuring both patient and provider safety by preventing direct physical contact, hence reducing morbidity and mortality during the COVID-19 pandemic [16,36,37].However, important safety concerns also manifested, predominantly concerning diagnostic uncertainty.In this context, previous literature also report GPs' concerns about clinical risk [38] and the need to establish escalation protocols to support clinicians decide when a transition to urgent inperson follow-up care, or even to emergency services, is required [37].Our results underline that remote digital tools may be an effective way of delivering primary care.In line with these findings, a Cochrane systematic review (2015) demonstrated the use of telemedicine strategies to be associated with increased access to care and improved clinical outcomes in single chronic diseases, particularly in type 2 diabetes [39].However, the interventions were heterogenous and the external generalisability of these findings remain unclear.Future research will be needed to address questions such as for which patients, and for which conditions, do virtual care tools actually improve effectiveness.Our participants highlighted that virtual care, particularly through remote triage, can reduce the number of unnecessary visits and thus have a positive impact on efficiency (i.e., minimising waste, including from an economic perspective).In fact, few telehealth evaluations have examined the association between outcomes and costs of virtual care.While some reviews have found that virtual care can decrease the use of acute hospital services [40][41][42], there is less evidence in the primary care context [43].On the other hand, our participants raised concerns about potential overuse and misuse by patients, which could negatively impact the effectiveness of remote care.In a recent study in Canada (2020) evaluating the uptake of a platform for virtual visits in primary care, Stamenova et al. observed that many virtual visits appeared to replace faceto-face visits, yet patients did not overwhelm physicians with requests [44].In what concerns timeliness of care, participants identified both potential advantages and disadvantages.Remote primary care has the potential to offer convenient access to a primary care provider without needing to take time-off work, arrange transportation, and spend time waiting for face-to-face visits.Participants were also concerned that barriers to the use of technology and difficulties inherent to a new mode of care delivery, could result in delays in diagnosis and treatment.There is sparse evidence on the subject.However, a recent study examined patient-initiated primary care visits in the Kaiser Permanente Northern California (a system with over four million members) and concluded that, on average, telephone visits were scheduled 50% sooner than office visits [45].These findings have profound implications, given that timeliness of care is associated with improved health outcomes.[46].Remote care has been promised to reduce inequities in access to care for decades, particularly in rural and geographically remote areas [47][48][49].In line with previous literature, our results demonstrate the ability of remote care to overcome barriers for those who have physical limitations to attend a face-to-face meeting, but also highlight their potential to entrench existing inequities in access to care [50,51].Published evidence shows that the transition to virtual primary care did not unfold in the same manner across communities [52].Proactive efforts are therefore needed to identify and address both patient and provider-related digital barriers so as to avoid that the widespread implementation of virtual care in a manner which reinforces disparities in health access amongst already underserved and excluded groups [52].Equally, with regards to patient-centredness, a range of benefits and challenges have been identified.While participants consider that remote care can improve convenience and patient empowerment, participants also acknowledge that it can have both negative and positive effects on communication.Another important challenge is patient preference for face-to-face visits.Preference theory suggests that patients would prefer a virtual consultation if they perceive its benefits as outweighing its burdens [53].Multiple factors may influence patients' preference, including the situation of care (i.e., patient's perception of their clinical status, treatment requirements, and care pathway), the expectations of care, the demand of care (e.g., social situation, consequences of choice), the capacity to allocate resources (e.g., patient's ability to allocate financial, infrastructural, social and healthcare resources) [54] and patients digital health literacy [55,56].These factors may combine or compete and may be dynamic throughout the patient's journey.The pandemic has a transformational impact in hastening the digital transformation, and in particular increasing awareness, trust, and adoption of remote care [16,57,58].Challenges such as the lack of support, burnout, and remuneration issues, are balanced by a few benefits (i.e., remote working and a better control over schedule).However, to fully embrace the benefits postulated (e.g., greater flexibility to work remotely from home), healthcare systems must explore and implement the enablers required.Potential enablers include single sign-on, sharing of records across systems, electronic generation of form, and the creation of workspaces and secure interfaces without the need for laptops and VPNs [59].While the rapid implementation of virtual consulting tools provides the ability to work more flexibly and from different locations, primary care leaders need to be supported and learn how to build effective teams via novel approaches [60].At the health systems level, previous studies have indicated that implementation barriers largely depended on accreditation, payment systems, and insurance [61].Prioritisation of financial investments into relevant infrastructure, greater emphasis on training and guidance for healthcare providers, and updates to the corresponding legal and regulatory frameworks supporting their use, are equally required.Overcoming institutional inertia is likely to be more feasible post-COVID-19, given that clinical culture is expected to have evolved substantially after a year of daily use of remote care delivery.In addition, as many of the existing guidance and policies on primary remote care were drafted and implemented during the emergency phase, the experience attained, and evidence collected offers an opportunity to refine, optimise, and update the relevant accompanying legal and regulatory frameworks.

Implications for research and policy
Based on our findings, we propose a framework of recommendations for the implementation of virtual care in the primary care setting (Figure 3).The framework consists of suggested action points across five specific domains for high-quality implementation of virtual care, including contextual considerations, technology infrastructure, awareness and experience, safety and risk management, and strategic planning & supporting policies (Figure 3).As part of this framework, we emphasise the importance of continuously monitoring quality across these five areas, which must be collected both through patient & provider feedback, but also using data-driven approaches to systematically evaluate the impact on equity (e.g., usage patterns and patients characteristics, patient preferences, and offer of alternative modes of consultation), effectiveness (e.g., longitudinal monitoring of impact on health outcomes, as well as of the technological, legal and regulatory infrastructure required to deliver effective care), and safety (e.g., longitudinal monitoring of safety indicators, including cybersecurity); efficiency (e.g., cost-effectiveness analysis) and timeliness (e.g., time-to-diagnosis and time-to-treatment).Decisions to adopt remote care services should be based on evidence of their impact, and responsive to ongoing evaluation & monitoring processes.
It is important to note that the technological and regulatory landscape is dynamic, as are patients' preferences.Therefore, virtual care platforms must be secure and reliable, but also flexible enough to accommodate evolving regulatory, professional, and health-care organisations' requirements [62] and processes must ensure that patients are presented with alternative options during their journey.Figure 3: A framework for implementation of virtual consultations in the primary care setting

Conclusion
At the frontlines of care delivery, GPs can provide valuable insights into the use of remote carewhat worked well, how, and why.Experience gained during the emergency phase of the COVID-19 pandemic can be used to inform the stable adoption of virtual care solutions, the co-designing of processes and platforms that are technologically robust, and supported by a strategic long-term plan.The development of such platforms should consider pre-existing health inequities and contextual considerations, and deliberately implement strategies to minimise digital exclusion and optimise patients' experience.Finally, primary care health systems need to rigorously evaluate the ongoing impact on virtual primary care both during and after the pandemic, and incorporate the lessons learned into legal and regulatory frameworks that support its long-term, sustainable use.
