Synthesis of findings
Six barriers to access and evidence for how digital communication may impact on these barriers were identified: practical access issues; lack of candidacy; lack of ability to communicate with healthcare professionals; patient-related barriers; negative experiences with healthcare service and staff; and stigmatising and negative reactions to patients.
Practical access issues
These were experienced by carers and people with mental health problems. The barriers identified were lack of respite care for care recipients,29 inflexible appointments,30 unknown waiting times,30 service availability,1 transport difficulties,31–33 difficulties negotiating appointments and receptionists,34 and the stress and discomfort of waiting in the waiting room.34
Digital clinical communication improved access to general practice as practical barriers were overcome. E-mail offered efficiency, speed, and flexibility, for example, patients and carers could use e-mail to communicate with their clinician while at work.13,35 Asynchronous technology can be used to communicate whenever is convenient for the patient or carer, reducing the need to negotiate receptionists or appointment systems, travel to the surgery, and use waiting rooms.35–38
Lack of candidacy
This was experienced by carers. The barrier identified was that health professionals focus on the needs of the care recipient, with the needs of the carer considered only in terms of what is needed to provide care.30,39–42 Increasing the range of channels through which carers can access general practice will not impact on perceived candidacy because identifying oneself as a candidate for health care is necessary before starting the help-seeking process.43
Lack of ability to communicate with healthcare professionals
This was experienced by refugees and asylum seekers, and people with mental health problems. The barriers identified were language barriers affecting the appointment booking and consultation,44–56 problematic access to professional interpreters,44,48–50,52,57–59 confidentiality fears with both professional and informal interpreters,44,49,58 and lack of discourse to describe mental health concerns.60,61
Digital clinical communication will not change the ability of these disadvantaged groups in communicating with health professionals, with the exception being language translation. There is an increased feeling of privacy when an interpreter is not physically present, which increases willingness to discuss sensitive issues.62 However, people whose first language is not English are not heavy users of digital communication in English-speaking countries,16,63 so this advantage may not be realised.
Patient-related barriers
These were experienced by refugees and asylum seekers, homeless people, and Gypsies and Travellers. The barriers identified were mobility of populations and lack of continuity,51,58,64 unwillingness to divulge address (for personal safety, such as women living in domestic violence shelters, or fear of legal repercussions, such as failed asylum seekers),65 and patients’ lack of knowledge about health service structure and how to access services.47,50
Digital clinical communication improves continuity of care for mobile populations and those unwilling to divulge their address,13,66,67 and the relative anonymity provided could encourage populations who wish to remain hidden to seek help.66,68 However, this type of communication alone will not improve knowledge about health service structure and how to access services. The authors were unable to find any evidence on these factors.
Negative experiences with healthcare service and staff
This was experienced by people with mental health problems, refugees and asylum seekers, homeless people, and Gypsies and Travellers. The barriers identified were staff not being seen as sensitive,44,55,69–71 difficult relationships with GPs,51,71–73 negative perceptions of GPs’ knowledge, skills, and empathy for mental health problems,34,60,61,74,75 distrust in GPs and their abilities,51 communication difficulties due to mental health problems,60 and service-wide lack of awareness of patients’ rights and acceptance of official documentation.52,58
Digital clinical communication will improve continuity of care from a trusted clinician, but where there is no existing patient–clinician relationship it will reduce the quality of communication between patient and clinician. Social presence theory76 states that interpersonal processes are negatively affected by interaction that takes place via media that reduces the feeling of ‘being there’ with each other. In order to build the therapeutic relationship, clinicians and patients need to have face-to-face contact for the richness of stimuli available, including auditory, visual, tactile, and olfactory.37 Patients try to see trusted GPs for mental health issues rather than the most available GP,77,78 prioritising relationship continuity over convenience. Text-based communication in well-established relationships is likely to be more successful than that between strangers because of the room for misinterpretation.37,79
Additionally, digital clinical communication would reduce the need for patients to engage with receptionists and other health centre staff,35–37 ameliorating apprehension about negative experiences with these staff.
No evidence was found that digital communication will in itself improve patients’ trust in general practice clinicians, or increase health services’ awareness of patients’ rights.
Stigmatising and negative reactions to patients
This was experienced by people with mental health problems, refugees and asylum seekers, homeless people, and Gypsies and Travellers. The barriers identified were stigma and hostile attitudes (from healthcare staff and other patients),50,56,60,73–75,81–84 embarrassment,74,85,86 fear,74 social (dis)approval,31,73 and perceived discrimination.32,73,86
Digital clinical communication may reduce patients’ inhibition and sense of intimidation, and promote patient disclosure and asking of questions. Patients consulting for physical problems feel less intimidated via video link and able to ask more questions.90 Kang and colleagues91 found that teenage girls willingly emailed a health professional in a magazine column to discuss problems/queries that they would not necessarily talk about face to face. Online disinhibition theory92 suggests that people express themselves more openly, disclose more, and say things in cyberspace that they would not face to face. The removal of the patient ‘being seen’ seeking help potentially removes the embarrassment, social disapproval, and stigma that some patients may experience at healthcare centres.68,93 Although one review suggested that face-to-face consultations were essential for communication about emotional states,87 other evidence suggests that patients do communicate their emotional states with GPs via e-mail,88 and are able to discuss embarrassing or sensitive questions.89
Table 1 summarises the barriers to general practice access, groups known to experience each barrier, evidence for the impact of digital clinical communication on each barrier, and emerging hypotheses of the impact of digital clinical communication on the barrier in question.
