A Symptom-Checker for Adult Patients Visiting an Interdisciplinary Emergency Care Center and the Safety of Patient Self-Triage: Real-Life Prospective Evaluation. J Med Internet Res 2024; 26:e58157. [PMID: 38809606 PMCID: PMC11240063 DOI: 10.2196/58157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 04/15/2024] [Accepted: 05/29/2024] [Indexed: 05/30/2024] Open
Abstract
BACKGROUND Symptom-checkers have become important tools for self-triage, assisting patients to determine the urgency of medical care. To be safe and effective, these tools must be validated, particularly to avoid potentially hazardous undertriage without leading to inefficient overtriage. Only limited safety data from studies including small sample sizes have been available so far. OBJECTIVE The objective of our study was to prospectively investigate the safety of patients' self-triage in a large patient sample. We used SMASS (Swiss Medical Assessment System; in4medicine, Inc) pathfinder, a symptom-checker based on a computerized transparent neural network. METHODS We recruited 2543 patients into this single-center, prospective clinical trial conducted at the cantonal hospital of Baden, Switzerland. Patients with an Emergency Severity Index of 1-2 were treated by the team of the emergency department, while those with an index of 3-5 were seen at the walk-in clinic by general physicians. We compared the triage recommendation obtained by the patients' self-triage with the assessment of clinical urgency made by 3 successive interdisciplinary panels of physicians (panels A, B, and C). Using the Clopper-Pearson CI, we assumed that to confirm the symptom-checkers' safety, the upper confidence bound for the probability of a potentially hazardous undertriage should lie below 1%. A potentially hazardous undertriage was defined as a triage in which either all (consensus criterion) or the majority (majority criterion) of the experts of the last panel (panel C) rated the triage of the symptom-checker to be "rather likely" or "likely" life-threatening or harmful. RESULTS Of the 2543 patients, 1227 (48.25%) were female and 1316 (51.75%) male. None of the patients reached the prespecified consensus criterion for a potentially hazardous undertriage. This resulted in an upper 95% confidence bound of 0.1184%. Further, 4 cases met the majority criterion. This resulted in an upper 95% confidence bound for the probability of a potentially hazardous undertriage of 0.3616%. The 2-sided 95% Clopper-Pearson CI for the probability of overtriage (n=450 cases,17.69%) was 16.23% to 19.24%, which is considerably lower than the figures reported in the literature. CONCLUSIONS The symptom-checker proved to be a safe triage tool, avoiding potentially hazardous undertriage in a real-life clinical setting of emergency consultations at a walk-in clinic or emergency department without causing undesirable overtriage. Our data suggest the symptom-checker may be safely used in clinical routine. TRIAL REGISTRATION ClinicalTrials.gov NCT04055298; https://clinicaltrials.gov/study/NCT04055298.

Abstract
BACKGROUND Many health care systems have used digital technologies to support care delivery, a trend amplified by the COVID-19 pandemic. "Digital first" may exacerbate health inequalities due to variations in eHealth literacy. The relationship between eHealth literacy and web-based urgent care service use is unknown. OBJECTIVE This study aims to measure the association between eHealth literacy and the use of NHS (National Health Service) 111 online urgent care service. METHODS A cross-sectional sequential convenience sample survey was conducted with 2754 adults (October 2020-July 2021) from primary, urgent, or emergency care; third sector organizations; and the NHS 111 online website. The survey included the eHealth Literacy Questionnaire (eHLQ), questions about use, preferences for using NHS 111 online, and sociodemographic characteristics. RESULTS Across almost all dimensions of the eHLQ, NHS 111 online users had higher mean digital literacy scores than nonusers (P<.001). Four eHLQ dimensions were significant predictors of use, and the most highly significant dimensions were eHLQ1 (using technology to process health information) and eHLQ3 (ability to actively engage with digital services), with odds ratios (ORs) of 1.86 (95% CI 1.46-2.38) and 1.51 (95% CI 1.22-1.88), respectively. Respondents reporting a long-term health condition had lower eHLQ scores. People younger than 25 years (OR 3.24, 95% CI 1.87-5.62) and those with formal qualifications (OR 0.74, 95% CI 0.55-0.99) were more likely to use NHS 111 online. Users and nonusers were likely to use NHS 111 online for a range of symptoms, including chest pain symptoms (n=1743, 70.4%) or for illness in children (n=1117, 79%). The users of NHS 111 online were more likely to have also used other health services, particularly the 111 telephone service (χ12=138.57; P<.001). CONCLUSIONS These differences in eHealth literacy scores amplify perennial concerns about digital exclusion and access to care for those impacted by intersecting forms of disadvantage, including long-term illness. Although many appear willing to use NHS 111 online for a range of health scenarios, indicating broad acceptability, not all are able or likely to do this. Despite a policy ambition for NHS 111 online to substitute for other services, it appears to be used alongside other urgent care services and thus may not reduce demand.

Abstract
STUDY OBJECTIVE There is increasing interest in harnessing artificial intelligence to virtually triage patients seeking care. The objective was to examine the reliability of a virtual machine learning algorithm to remotely predict acuity scores for patients seeking emergency department (ED) care by applying the algorithm to retrospective ED data. METHODS This was a retrospective review of adult patients conducted at an academic tertiary care ED (annual census 65,000) from January 2021 to August 2022. Data including ED visit date and time, patient age, sex, reason for visit, presenting complaint and patient-reported pain score were used by the machine learning algorithm to predict acuity scores. The algorithm was designed to up-triage high-risk complaints to promote safety for remote use. The predicted scores were then compared to nurse-led triage scores previously derived in real time using the electronic Canadian Triage and Acuity Scale (eCTAS), an electronic triage decision-support tool used in the ED. Interrater reliability was estimated using kappa statistics with 95% confidence intervals (CIs). RESULTS In total, 21,469 unique ED patient encounters were included. Exact modal agreement was achieved for 10,396 (48.4%) patient encounters. Interrater reliability ranged from poor to fair, as estimated using unweighted kappa (0.18, 95% CI 0.17 to 0.19), linear-weighted kappa (0.25, 95% CI 0.24 to 0.26), and quadratic-weighted kappa (0.36, 95% CI 0.35 to 0.37) statistics. Using the nurse-led eCTAS score as the reference, the machine learning algorithm overtriaged 9,897 (46.1%) and undertriaged 1,176 (5.5%) cases. Some of the presenting complaints under-triaged were conditions generally requiring further probing to delineate their nature, including abnormal lab/imaging results, visual disturbance, and fever. CONCLUSION This machine learning algorithm needs further refinement before being safely implemented for patient use.

Abstract
Background Care homes predominantly care for older people with complex health and care needs, who are at high risk of unplanned hospital admissions. While often necessary, such admissions can be distressing and provide an opportunity cost as well as a financial cost. Objectives Our objective was to update a 2014 evidence review of interventions to reduce unplanned admissions of care home residents. We carried out a systematic review of interventions used in the UK and other high-income countries by synthesising evidence of effects of these interventions on hospital admissions; feasibility and acceptability; costs and value for money; and factors affecting applicability of international evidence to UK settings. Data sources We searched the following databases in December 2021 for studies published since 2014: Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews; Cumulative Index to Nursing and Allied Health Literature; Health Management Information Consortium; Medline; PsycINFO; Science and Social Sciences Citation Indexes; Social Care Online; and Social Service Abstracts. 'Grey' literature (January 2022) and citations were searched and reference lists were checked. Methods We included studies of any design reporting interventions delivered in care homes (with or without nursing) or hospitals to reduce unplanned hospital admissions. A taxonomy of interventions was developed from an initial scoping search. Outcomes of interest included measures of effect on unplanned admissions among care home residents; barriers/facilitators to implementation in a UK setting and acceptability to care home residents, their families and staff. Study selection, data extraction and risk of bias assessment were performed by two independent reviewers. We used published frameworks to extract data on intervention characteristics, implementation barriers/facilitators and applicability of international evidence. We performed a narrative synthesis grouped by intervention type and setting. Overall strength of evidence for admission reduction was assessed using a framework based on study design, study numbers and direction of effect. Results We included 124 publications/reports (30 from the UK). Integrated care and quality improvement programmes providing additional support to care homes (e.g. the English Care Homes Vanguard initiatives and hospital-based services in Australia) appeared to reduce unplanned admissions relative to usual care. Simpler training and staff development initiatives showed mixed results, as did interventions aimed at tackling specific problems (e.g. medication review). Advance care planning was key to the success of most quality improvement programmes but do-not-hospitalise orders were problematic. Qualitative research identified tensions affecting decision-making involving paramedics, care home staff and residents/family carers. The best way to reduce end-of-life admissions through access to palliative care was unclear in the face of inconsistent and generally low-quality evidence. Conclusions Effective implementation of interventions at various stages of residents' care pathways may reduce unplanned admissions. Most interventions are complex and require adaptation to local contexts. Work at the interface between health and social care is key to successful implementation. Limitations Much of the evidence identified was of low quality because of factors such as uncontrolled study designs and small sample size. Meta-analysis was not possible. Future work We identified a need for improved economic evidence and the evaluation of integrated care models of the type delivered by hospital-based teams. Researchers should carefully consider what is realistic in terms of study design and data collection given the current context of extreme pressure on care homes.

Point-of-Care Ultrasound for the Evaluation and Management of Posterior Cruciate Ligament Injuries: A Systematic Review. Diagnostics (Basel) 2023; 13:2352. [PMID: 37510096 PMCID: PMC10378212 DOI: 10.3390/diagnostics13142352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 07/07/2023] [Accepted: 07/11/2023] [Indexed: 07/30/2023] Open
Abstract
Posterior cruciate ligament (PCL) injuries, though less common than other knee ligament injuries, pose significant management challenges. This study aimed to systematically review and analyze the current evidence on the use of point-of-care ultrasound (POCUS) for the evaluation and management of PCL injuries. It was hypothesized that POCUS has comparable diagnostic accuracy to magnetic resonance imaging (MRI) and that the use of POCUS improves patient outcomes and reduces healthcare costs. A comprehensive systematic review of articles published up to April 2023 was conducted using PubMed, Web of Science, Cochrane, and Scopus databases and adhered to the PRISMA guidelines. Studies were selected based on relevance to the research question, with a focus on diagnostic accuracy, reliability, clinical utility, and cost-effectiveness of POCUS in PCL injuries. Seven studies, analyzing a total of 242 patients with PCL injuries, were included. The reported sensitivity and specificity of POCUS for diagnosing PCL injuries ranged from 83.3% to 100% and 86.7% to 100%, respectively, across the studies. In one study, POCUS demonstrated a positive predictive value (PPV) of 87.9% and a negative predictive value (NPV) of 82.4%. Additionally, three studies reported 100% accuracy in PCL injury detection using POCUS, suggesting a substantial potential for cost savings by eliminating the need for MRI. This systematic review supports the use of POCUS in the evaluation and management of PCL injuries, suggesting that POCUS is a reliable, cost-effective tool with high diagnostic accuracy comparable to that of MRI, offering the potential to improve patient outcomes and reduce healthcare costs. The data collated in this review can inform clinical practice and guide future research in the field.

Abstract
Background NHS 111 online offers 24-hour access to health assessment and triage. Objectives This study examined pathways to care, differential access and use, and workforce impacts of NHS 111 online. This study compared NHS 111 with Healthdirect (Haymarket, Australia) virtual triage. Design Interviews with 80 staff and stakeholders in English primary, urgent and emergency care, and 41 staff and stakeholders associated with Healthdirect. A survey of 2754 respondents, of whom 1137 (41.3%) had used NHS 111 online and 1617 (58.7%) had not. Results NHS 111 online is one of several digital health-care technologies and was not differentiated from the NHS 111 telephone service or well understood. There is a similar lack of awareness of Healthdirect virtual triage. NHS 111 and Healthdirect virtual triage are perceived as creating additional work for health-care staff and inappropriate demand for some health services, especially emergency care. One-third of survey respondents reported that they had not used any NHS 111 service (telephone or online). Older people and those with less educational qualifications are less likely to use NHS 111 online. Respondents who had used NHS 111 online reported more use of other urgent care services and make more cumulative use of services than those who had not used NHS 111 online. Users of NHS 111 online had higher levels of self-reported eHealth literacy. There were differences in reported preferences for using NHS 111 online for different symptom presentations. Conclusions Greater clarity about what the NHS 111 online service offers would allow better signposting and reduce confusion. Generic NHS 111 services are perceived as creating additional work in the primary, urgent and emergency care system. There are differences in eHealth literacy between users and those who have not used NHS 111 online, and this suggests that 'digital first' policies may increase health inequalities. Limitations This research bridged the pandemic from 2020 to 2021; therefore, findings may change as services adjust going forward. Surveys used a digital platform so there is probably bias towards some level of e-Literacy, but this also means that our data may underestimate the digital divide. Future work Further investigation of access to digital services could address concerns about digital exclusion. Research comparing the affordances and cost-benefits of different triage and assessment systems for users and health-care providers is needed. Research about trust in virtual assessments may show how duplication can be reduced. Mixed-methods studies looking at outcomes, impacts on work and costs, and ways to measure eHealth literacy, can inform the development NHS 111 online and opportunities for further international shared learning could be pursued.

Abstract
Symptom Checker Applications (SCA) are mobile applications often designed for the end-user to assist with symptom assessment and self-triage. SCA are meant to provide the user with easily accessible information about their own health conditions. However, SCA raise questions regarding ethical, legal, and social aspects (ELSA), for example, regarding fair access to this new technology. The aim of this scoping review is to identify the ELSA of SCA in the scientific literature. A scoping review was conducted to identify the ELSA of SCA. Ten databases (e.g., Web of Science and PubMed) were used. Studies on SCA that address ELSA, written in English or German, were included in the review. The ELSA of SCA were extracted and synthesized using qualitative content analysis. A total of 25,061 references were identified, of which 39 were included in the analysis. The identified aspects were allotted to three main categories: (1) Technology; (2) Individual Level; and (3) Healthcare system. The results show that there are controversial debates in the literature on the ethical and social challenges of SCA usage. Furthermore, the debates are characterised by a lack of a specific legal perspective and empirical data. The review provides an overview on the spectrum of ELSA regarding SCA. It offers guidance to stakeholders in the healthcare system, for example, patients, healthcare professionals, and insurance providers and could be used in future empirical research to investigate the perspectives of those affected, such as users.

Abstract
BACKGROUND The national Omaolo digital social welfare and health care service of Finland provides a symptom checker, Omaolo, which is a medical device (based on Duodecim Clinical Decision Support EBMEDS software) with a CE marking (risk class IIa), manufactured by the government-owned DigiFinland Oy. Users of this service can perform their triage by using the questions in the symptom checker. By completing the symptom checker, the user receives a recommendation for action and a service assessment with appropriate guidance regarding their health problems on the basis of a selected specific symptom in the symptom checker. This allows users to be provided with appropriate health care services, regardless of time and place. OBJECTIVE This study describes the protocol for the mixed methods validation process of the symptom checker available in Omaolo digital services. METHODS This is a mixed methods study using quantitative and qualitative methods, which will be part of the clinical validation process that takes place in primary health care centers in Finland. Each organization provides a space where the study and the nurse triage can be done in order to include an unscreened target population of users. The primary health care units provide walk-in model services, where no prior phone call or contact is required. For the validation of the Omaolo symptom checker, case vignettes will be incorporated to supplement the triage accuracy of rare and acute cases that cannot be tested extensively in real-life settings. Vignettes are produced from a variety of clinical sources, and they test the symptom checker in different triage levels by using 1 standardized patient case example. RESULTS This study plan underwent an ethics review by the regional permission, which was requested from each organization participating in the research, and an ethics committee statement was requested and granted from Pirkanmaa hospital district's ethics committee, which is in accordance with the University of Tampere's regulations. Of 964 clinical user-filled symptom checker assessments, 877 cases were fully completed with a triage result, and therefore, they met the requirements for clinical validation studies. The goal for sufficient data has been reached for most of the chief symptoms. Data collection was completed in September 2019, and the first feasibility and patient experience results were published by the end of 2020. Case vignettes have been identified and are to be completed before further testing the symptom checker. The analysis and reporting are estimated to be finalized in 2024. CONCLUSIONS The primary goals of this multimethod electronic symptom checker study are to assess safety and to provide crucial information regarding the accuracy and usability of the Omaolo electronic symptom checker. To our knowledge, this will be the first study to include real-life clinical cases along with case vignettes. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID) DERR1-10.2196/41423.

Abstract
Online symptom checkers (SCs) are eHealth solutions that offer healthcare organizations the possibility to empower their patients to independently assess their symptoms. The successful implementation of eHealth solutions, such as SCs, requires a supportive organizational culture and leadership. However, there is limited knowledge about the factors associated with leaders' support for the use of SCs. The aim of the study was to identify the factors associated to primary care leaders' support for SCs in triage and their experiences of the benefits and challenges related to the use of SCs. An online survey was used to collect data from 84 Finnish primary care leaders. The data were analyzed using statistical analysis methods and content analysis. Vision clarity, perceiving efficiency improvements, and considering the service to be beneficial for patients were associated with leaders' support for the service (β ranging from 0.41 to 0.44, p < 0.001). Leaders' support for the service was also associated with how well the leaders provided information about the service to their subordinates (β =0.22, p < 0.048). SCs present slightly more challenges than benefits regarding health professionals' work. The developers of SCs should focus more on features that decrease health professionals' workload as well as how the solution can benefit patients.

Impact of NHS 111 Online on the NHS 111 telephone service and urgent care system: a mixed-methods study. HEALTH SERVICES AND DELIVERY RESEARCH 2021.

Abstract
Background
The NHS emergency and urgent care system is under pressure as demand for services increases each year. NHS 111 is a telephone triage service designed to provide advice and signposting to appropriate services for people with urgent health-care problems. A new service, NHS 111 Online, has been introduced across England as a digital alternative that can be accessed using a website or a smartphone application. The effects and usefulness of this service are unknown.
Objectives
To explore the impact of NHS 111 Online on the related telephone service and urgent care system activity and the experiences of people who use those services.
Design and methods
A mixed-methods design of five related work packages comprising an evidence review; a quantitative before-and-after time series analysis of changes in call activity (18/38 sites); a descriptive comparison of telephone and online services with qualitative survey (telephone, n = 795; online, n = 3728) and interview (32 participants) studies of service users; a qualitative interview study (16 participants) of staff; and a cost–consequences analysis.
Results
The online service had little impact on the number of triaged calls to the NHS 111 telephone service. For every 1000 online contacts, triaged telephone calls increased by 1.3% (1.013, 95% confidence interval 0.996 to 1.029; p = 0.127). Recommendations to attend emergency and urgent care services increased between 6.7% and 4.2%. NHS 111 Online users were less satisfied than users of the telephone service (50% vs. 71%; p < 0.001), and less likely to recommend to others (57% vs. 69%; p < 0.001) and to report full compliance with the advice given (67.5% vs. 88%; p < 0.001). Online users were less likely to report contacting emergency services and more likely to report not making any contact with a health service (31% vs. 16%; p < 0.001) within 7 days of contact. Thirty-five per cent of online users reported that they did not want to use the telephone service, whereas others preferred its convenience and speed. NHS 111 telephone staff reported no discernible increase or decrease in their workload during the first year of operation of NHS 111 Online. If online and telephone services operate in parallel, then the annual costs will be higher unless ≥ 38% of telephone contacts move to online contacts.
Conclusions
There is some evidence that the new service has the potential to create new demand. The service has expanded significantly, so it is important to find ways of promoting the right balance in numbers of people who use the online service instead of the telephone service if it is to be effective. There is a clear need and preference by some people for an online service. Better information about when to use this service and improvements to questioning may encourage more uptake.
Limitations
The lack of control arm means that impact could have been an effect of other factors. This work took place during the early implementation phase, so findings may change as the service expands.
Future work
Further development of the online triage process to make it more ‘user friendly’ and to enable users to trust the advice given online could improve use and increase satisfaction. Better understanding of the characteristics of the telephone and online populations could help identify who is most likely to benefit and could improve information about when to use the service.

Abstract
Background A large number of web-based COVID-19 symptom checkers and chatbots have been developed; however, anecdotal evidence suggests that their conclusions are highly variable. To our knowledge, no study has evaluated the accuracy of COVID-19 symptom checkers in a statistically rigorous manner. Objective The aim of this study is to evaluate and compare the diagnostic accuracies of web-based COVID-19 symptom checkers. Methods We identified 10 web-based COVID-19 symptom checkers, all of which were included in the study. We evaluated the COVID-19 symptom checkers by assessing 50 COVID-19 case reports alongside 410 non–COVID-19 control cases. A bootstrapping method was used to counter the unbalanced sample sizes and obtain confidence intervals (CIs). Results are reported as sensitivity, specificity, F1 score, and Matthews correlation coefficient (MCC). Results The classification task between COVID-19–positive and COVID-19–negative for “high risk” cases among the 460 test cases yielded (sorted by F1 score): Symptoma (F1=0.92, MCC=0.85), Infermedica (F1=0.80, MCC=0.61), US Centers for Disease Control and Prevention (CDC) (F1=0.71, MCC=0.30), Babylon (F1=0.70, MCC=0.29), Cleveland Clinic (F1=0.40, MCC=0.07), Providence (F1=0.40, MCC=0.05), Apple (F1=0.29, MCC=-0.10), Docyet (F1=0.27, MCC=0.29), Ada (F1=0.24, MCC=0.27) and Your.MD (F1=0.24, MCC=0.27). For “high risk” and “medium risk” combined the performance was: Symptoma (F1=0.91, MCC=0.83) Infermedica (F1=0.80, MCC=0.61), Cleveland Clinic (F1=0.76, MCC=0.47), Providence (F1=0.75, MCC=0.45), Your.MD (F1=0.72, MCC=0.33), CDC (F1=0.71, MCC=0.30), Babylon (F1=0.70, MCC=0.29), Apple (F1=0.70, MCC=0.25), Ada (F1=0.42, MCC=0.03), and Docyet (F1=0.27, MCC=0.29). Conclusions We found that the number of correctly assessed COVID-19 and control cases varies considerably between symptom checkers, with different symptom checkers showing different strengths with respect to sensitivity and specificity. A good balance between sensitivity and specificity was only achieved by two symptom checkers.

BMC Med 2020; 18:117.

Abstract
BACKGROUND Reconfiguration of urgent and emergency care services often increases travel time/distance for patients to reach an appropriate facility. Evidence of the effects of reconfiguration is important for local communities and commissioners and providers of health services. METHODS We performed a systematic review of the evidence regarding effects of service reconfigurations that increase the time/distance for some patients to reach an urgent and emergency care (UEC) facility. We searched seven bibliographic databases from 2000 to February 2019 and used citation tracking and reference lists to identify additional studies. We included studies of any design that compared outcomes for people with conditions requiring emergency treatment before and after service reconfiguration with an associated change in travel time/distance to access UEC. Studies had to be conducted in the UK or other developed countries. Data extraction and quality assessment (using the Joanna Briggs Institute checklist for quasi-experimental studies) were undertaken by a single reviewer with a sample checked for accuracy and consistency. We performed a narrative synthesis of the included studies. Overall strength of evidence was assessed using a previously published method that considers volume, quality and consistency. RESULTS We included 12 studies, of which six were conducted in the USA, two in the UK and four in other European countries. The studies used a variety of observational designs, with before-after and cohort designs being most common. Only two studies included an independent control site/sites where no reconfiguration had taken place. The reconfigurations evaluated in these studies reported relatively small effects on average travel times/distance. DISCUSSION For studies of general UEC populations, there was no convincing evidence as to whether reconfiguration affected mortality risk. However, evidence of increased risk was identified from studies of patients with acute myocardial infarction, particularly 1 to 4 years after reconfiguration. Evidence for other conditions was inconsistent or very limited. CONCLUSIONS We found insufficient evidence to determine whether increased distance to UEC increases mortality risk for the general population of people requiring UEC, although this conclusion may not extend to people with specific conditions.

Rodgers M, Raine G, Thomas S, Harden M, Eastwood A. Informing NHS policy in ‘digital-first primary care’: a rapid evidence synthesis. HEALTH SERVICES AND DELIVERY RESEARCH 2019. [DOI: 10.3310/hsdr07410] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022] Open
Abstract
Background
In ‘digital-first primary care’ models of health-care delivery, a patient’s first point of contact with a general practitioner or other health professional is through a digital channel, rather than a face-to-face consultation. Patients are able to access advice and treatment remotely from their home or workplace via a number of different technologies.
Objectives
This rapid responsive evidence synthesis was undertaken to inform NHS England policy in ‘digital-first primary care’. It was conducted in two stages: (1) scoping the published evidence and (2) addressing a refined set of questions produced by NHS England from the evidence retrieved during the scoping stage.
Data sources
Searches were conducted of five electronic databases (MEDLINE, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, the Health Technology Assessment database and PROSPERO were searched in July 2018) and relevant research/policy and government websites, as well as the National Institute for Health Research Health Service and Delivery Research programme database of ongoing and completed projects. No date or geographical limitations were applied.
Review methods
After examining the initial scoping material, NHS England provided a list of questions relating to the potential effects of digital modes and models of engagement, and the contracting and integration of these models into primary care. Systematic reviews and evidence syntheses, including evidence on the use of digital (online) modes and models of engagement between patients and primary care, were examined more closely, as was ongoing research and any incidentally identified primary studies focused on the use of digital (online) modes and models of engagement. All records were screened by two reviewers, with disagreements resolved by consensus or consulting a third reviewer.
Results
Evidence suggests that uptake of existing digital modes of engagement is currently low. Patients who use digital alternatives to face-to-face consultations are likely to be younger, female and have higher income and education levels. There is some evidence that online triage tools can divert demand away from primary care, but results vary between interventions and outcome measures. A number of potential barriers exist to using digital alternatives to face-to-face consultations, including inadequate NHS technology and staff concerns about workload and confidentiality. There are currently insufficient empirical data to either substantiate or allay such concerns. Very little evidence exists on outcomes related to quality of care, service delivery, benefits or harms for patients, or on financial costs/cost-effectiveness. No studies examining how to contract and commission alternatives to face-to-face consultations were identified.
Limitations
The quality of the included reviews was variable. Poor reporting of methodology and a lack of adequate study details were common issues. Much of the evidence focused on exploring stakeholder views rather than on objective measurement of potential impacts. The current evidence synthesis is based on a rapid scoping exercise and cannot provide the breadth or depth of insight that might have been achieved with a full systematic review.
Conclusions
Rapid scoping of the literature suggests that there is little high-quality evidence relating to ‘digital-first primary care’ as defined by NHS England. The broader evidence on alternatives to face-to-face consultation addresses certain policy-maker concerns, such as the possible impact of new technologies on workload and workforce, inequalities, local implementation and integration with existing services. However, although this evidence gives an insight into the views and experiences of health professionals in relation to such concerns, quantitative empirical data are lacking.
