Huang S, Liang Y, Li J, Li X. Applications of Clinical Decision Support Systems in Diabetes Care: Scoping Review. J Med Internet Res 2023; 25:e51024. [PMID: 38064249 PMCID: PMC10746969 DOI: 10.2196/51024] [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: 07/21/2023] [Revised: 11/10/2023] [Accepted: 11/12/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Providing comprehensive and individualized diabetes care remains a significant challenge in the face of the increasing complexity of diabetes management and a lack of specialized endocrinologists to support diabetes care. Clinical decision support systems (CDSSs) are progressively being used to improve diabetes care, while many health care providers lack awareness and knowledge about CDSSs in diabetes care. A comprehensive analysis of the applications of CDSSs in diabetes care is still lacking. OBJECTIVE This review aimed to summarize the research landscape, clinical applications, and impact on both patients and physicians of CDSSs in diabetes care. METHODS We conducted a scoping review following the Arksey and O'Malley framework. A search was conducted in 7 electronic databases to identify the clinical applications of CDSSs in diabetes care up to June 30, 2022. Additional searches were conducted for conference abstracts from the period of 2021-2022. Two researchers independently performed the screening and data charting processes. RESULTS Of 11,569 retrieved studies, 85 (0.7%) were included for analysis. Research interest is growing in this field, with 45 (53%) of the 85 studies published in the past 5 years. Among the 58 (68%) out of 85 studies disclosing the underlying decision-making mechanism, most CDSSs (44/58, 76%) were knowledge based, while the number of non-knowledge-based systems has been increasing in recent years. Among the 81 (95%) out of 85 studies disclosing application scenarios, the majority of CDSSs were used for treatment recommendation (63/81, 78%). Among the 39 (46%) out of 85 studies disclosing physician user types, primary care physicians (20/39, 51%) were the most common, followed by endocrinologists (15/39, 39%) and nonendocrinology specialists (8/39, 21%). CDSSs significantly improved patients' blood glucose, blood pressure, and lipid profiles in 71% (45/63), 67% (12/18), and 38% (8/21) of the studies, respectively, with no increase in the risk of hypoglycemia. CONCLUSIONS CDSSs are both effective and safe in improving diabetes care, implying that they could be a potentially reliable assistant in diabetes care, especially for physicians with limited experience and patients with limited access to medical resources.

Abstract
OBJECTIVE To develop and evaluate a novel Web-based Simulation Tool (WST) that brings simulation technologies to people with Type 1 Diabetes (T1D), enabling unique patient-data interactions seamlessly on a daily basis. METHODS A pilot clinical trial was conducted to assess system usability. The study consisted of one week of observation (Phase 1) and four weeks of interaction with WST (Phase 2). Responses to Technology Acceptance (TA) and Diabetes Distress Scale (DDS) questionnaires were collected, and follow-up interviews were conducted after Phase 2. RESULTS Fifteen participants with T1D using Control-IQ technology (age: 36 ± 13 years, HbA1c: 6.5% ± 0.7%) completed all study procedures. Generated simulation models achieved a median Mean Absolute Relative Difference (MARD) of 6.8% [interquartile range, IQR: 5.1%, 9.1%]. A decrease in expected benefits (likely explained by issues with the third-party data collection system) and an increase in expected burdens were observed. On a 1-5 scale, ease of use, trust, and usefulness scores were 3 [3,4], 4 [3,4], and 4 [3,4], respectively. Time below 70 mg/dL decreased between Phases 1 and 2 (1.6% [0.7%,3.7%] vs 0.8% [0.5%,3.0%]). A reduction in mean emotional burden was also observed (2.5 ± 1.1 vs 2.1 ± 0.8). CONCLUSIONS Results indicate that there was a learning curve to WST, but also that most participants trusted the system and found it useful in their diabetes care. SIGNIFICANCE Simulation technologies like WST could be used by educators and patients to facilitate diabetes self-management, leading to better diabetes literacy and reducing associated distress.

Abstract
Background This systematic review aimed to explore the enablers and barriers faced by adults with diabetes using two-way information communication technologies to support diabetes self-management. Methods Relevant literature was obtained from five databases using search strategies combining four major constructs: adults with diabetes, biomedical technology, communication technology and patient utilisation. Results Of 8430 unique articles identified, 48 were included for review. Risk of bias was assessed using either the Newcastle-Ottowa or Cochrane risk of bias assessment tools. Seventy-one percent of studies were of cohort design with the majority of studies assessed at high or unclear risk of bias. Consistently identified barriers included poorly designed interfaces requiring manual data entry and systems that lacked functionalities valued by patients. Commonly cited enablers included access to reliable technology, highly automated data entry and transmission, graphical display of data with immediate feedback, and supportive health care professionals and family members. Conclusions People with diabetes face a number of potentially modifiable barriers in using technology to support their diabetes management. In order to address these barriers, end users should be consulted in the design process and consideration given to theories of technology adoption to inform design and implementation. Systems should be designed to solve clinical or behavioural problems that are identified by patients as priorities. Technology should be as automated, streamlined, mobile, low cost and integrated as possible in order to limit the burden of usage for the patient and maximise clinical usefulness.

Abstract
We designed a study to evaluate the feasibility, acceptability and effectiveness of an Internet-based self-management system for diabetes. The Virtual Clinic allows a patient to communicate with health professionals, find information and participate in peer-to-peer discussions. Three focus groups were conducted with patients, and there were six interviews with health-care professionals and an expert workshop to gather consensus. All the people who were consulted were enthusiastic about the Virtual Clinic concept and perceived clear benefits in terms of improved self-management. The principal study design problems were: (1) choice and design of intervention; (2) outcome measures; (3) how much of the study is Internet-based; (4) data security and confidentiality. Our results suggest that a well-designed intervention study is possible. It will allow the evaluation of the feasibility, acceptability and effectiveness of the intervention in the context of the UK National Health Service.

BMC Health Serv Res 2015; 15:355. [PMID: 26330299 PMCID: PMC4557865 DOI: 10.1186/s12913-015-0938-5] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2015] [Accepted: 07/06/2015] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Successful diabetes disease management involves routine medical care with individualized patient goals, self-management education and on-going support to reduce complications. Without interventions that facilitate patient scheduling, improve attendance to provider appointments and provide patient information to provider and care team, preventive services cannot begin. This review examines interventions based upon three focus areas: 1) scheduling the patient with their provider; 2) getting the patient to their appointment, and; 3) having patient information integral to their diabetes care available to the provider. This study identifies interventions that improve appointment management and preparation as well as patient clinical and behavioral outcomes. METHODS A systematic review of the literature was performed using MEDLINE, CINAHL and the Cochrane library. Only articles in English and peer-reviewed articles were chosen. A total of 77 articles were identified that matched the three focus areas of the literature review: 1) on the schedule, 2) to the visit, and 3) patient information. These focus areas were utilized to analyze the literature to determine intervention trends and identify those with improved diabetes clinical and behavioral outcomes. RESULTS The articles included in this review were published between 1987 and 2013, with 46 of them published after 2006. Forty-two studies considered only Type 2 diabetes, 4 studies considered only Type 1 diabetes, 15 studies considered both Type 1 and Type 2 diabetes, and 16 studies did not mention the diabetes type. Thirty-five of the 77 studies in the review were randomized controlled studies. Interventions that facilitated scheduling patients involved phone reminders, letter reminders, scheduling when necessary while monitoring patients, and open access scheduling. Interventions used to improve attendance were letter reminders, phone reminders, short message service (SMS) reminders, and financial incentives. Interventions that enabled routine exchange of patient information included web-based programs, phone calls, SMS, mail reminders, decision support systems linked to evidence-based treatment guidelines, registries integrated with electronic medical records, and patient health records. CONCLUSIONS The literature review showed that simple phone and letter reminders for scheduling or prompting of the date and time of an appointment to more complex web-based multidisciplinary programs with patient self-management can have a positive impact on clinical and behavioral outcomes for diabetes patients. Multifaceted interventions aimed at appointment management and preparation during various phases of the medical outpatient care process improves diabetes disease management.

Abstract
BACKGROUND Recent advances in information technology (IT) coupled with the increased ubiquitous nature of information technology (IT) present unique opportunities for improving diabetes self-management. The objective of this paper is to determine, in a systematic review, how IT has been used to improve self-management for adults with Type 1 and Type 2 diabetes. METHODS The review covers articles extracted from relevant databases using search terms related information technology and diabetes self-management published after 1970 until August 2012. Additional articles were extracted using the citation map in Web of Science. Articles representing original research describing the use of IT as an enabler for self-management tasks performed by the patient are included in the final analysis. RESULTS Overall, 74% of studies showed some form of added benefit, 13% articles showed no-significant value provided by IT, and 13% of articles did not clearly define the added benefit due to IT. Information technologies used included the Internet (47%), cellular phones (32%), telemedicine (12%), and decision support techniques (9%). Limitations and research gaps identified include usability, real-time feedback, integration with provider electronic medical record (EMR), as well as analytics and decision support capabilities. CONCLUSION There is a distinct need for more comprehensive interventions, in which several technologies are integrated in order to be able to manage chronic conditions such as diabetes. Such IT interventions should be theoretically founded and should rely on principles of user-centered and socio-technical design in its planning, design and implementation. Moreover, the effectiveness of self-management systems should be assessed along multiple dimensions: motivation for self-management, long-term adherence, cost, adoption, satisfaction and outcomes as a final result.

Abstract
With significant declines in cardiovascular disease (CVD) mortality, attention has shifted to patient management. Programs designed to manage CVD require the involvement of health professionals for comanagement and patients' self-management. However, these programs are commonly limited to large urban centers, resulting in limited access for rural patients. The use of telehealth potentially overcomes geographical barriers and can improve access to care for patients. The current research explores how an Internet-based platform might facilitate collaboration among healthcare providers comanaging patients and enhance behavioural change in patients. Forty-eight participants were interviewed including: (a) patients (n = 12), (b) physicians (n = 11), (c) nurses (n = 13), and (d) allied health professionals (n = 10). The results were organized and analyzed in three central themes: (1) role of technology for CVD management, (2) challenges to technology adoption, and (3) incentives for technology adoption. Health care providers and patients supported future implementation of Internet-based technology support for CVD management.

Abstract
BACKGROUND Patients living outside of urban centres do not have access to the same level of care as patients in cities. The use of the Internet has been suggested as a possible resolution to this geographic inequity. OBJECTIVE To identify the determinants of Internet use in patients with cardiovascular disease and the patterns of use. METHODS Cardiac inpatients of an urban tertiary and a northern regional hospital in British Columbia were invited to participate. Patients who could not speak English or who had mental impairment were excluded. Consenting patients were interviewed regarding demographics and home Internet use. RESULTS A total of 294 patients participated. The mean (+/- SD) age was 64.0+/-12.7 years. Most participants were men (68%) of European ancestry (77%) with some postsecondary education (57%). All geographical regions of British Columbia were represented. A total of 66% of patients had home Internet access. In rural areas, 47% of patients had access to the Internet (P=0.020 compared with nonrural areas). Eighty-four per cent of patients with Internet access had a high-speed connection, 55% reported using the Internet daily and 23% used it more than once per week. Accessing health information from the Internet was reported by 70% of patients. CONCLUSION These data indicate a high prevalence of Internet use among English-speaking cardiac patients and a strong desire to obtain health information using the Internet. Health care organizations can take advantage of the Internet to develop and evaluate the delivery of cardiac services to patients in their homes, particularly to patients in rural and remote communities.

Abstract
BACKGROUND Use of the Internet for health information by patients is growing, and there have been diverse responses to this both within the research community and the medical and health-related professions. The use of Internet discussion boards are one way that people living with long-term conditions can interact with their peers and offer and seek advice, support and information. We report patient perspectives on using a discussion board within a wider pilot study of an Internet-based self-management system for diabetes. DESIGN Qualitative data was gathered during three stages of developing and piloting the wider self-management system. These are: (1) patient focus groups as part of a stakeholder consultation; (2) a pre-test session and focus group; and 3. a 6-month pilot study including follow-up individual interviews. RESULTS Three main themes were identified within participants' perspectives on Internet discussion boards. First, a focus on the importance and value of peer support to these patients. Secondly, participants' awareness of the need to evaluate the information posted by others in light of their own circumstances. Thirdly, the value placed upon the experiential knowledge of others living with the same condition. CONCLUSIONS Many people living with long-term conditions would like to be in contact with their peers, and Internet discussion boards represent a cost-effective and interactive way of achieving this. Within the context of diabetes, the knowledge and expertise accumulated over many years of self-management is central to participants' self-reported ability to evaluate information posted and make decisions on its possible use.

Abstract
Background Internet-based interventions to assist in diabetes management have the potential to provide patients with the information and support they need to become effective self-managers. Objective To assess the feasibility, acceptability, and effectiveness of an Internet-based virtual clinic designed to facilitate self-management in patients who used insulin pumps to manage their diabetes. Methods For a period of 6 months, 17 patients joined the virtual clinic. The system allowed patients to communicate with health professionals, interact with peers and access information. HbA1c, quality of life, and self-efficacy were monitored at baseline and after 6 months. Questionnaires and qualitative interviews examined patient experiences. Results Participants found the virtual clinic easy to use and positively rated its design. Peer support was the most valued aspect and the discussion boards the most used component. All participants highly rated the virtual clinic in terms of improving communication with peers, but few agreed it had improved communication with health care professionals. No significant improvements in physiological and psychological measurements were found. Regarding HbA1c measurements, there was no significant difference found between the pre- and post-test results (P = .53). Mean ADDQoL scores at baseline were -2.1 (SD 1.1, range -3.4 to -0.5) compared to -2.0 (SD 1.2, range, -4.6 to -0.4) post-test (n = 12), (P = .62). Surprisingly, patients’ confidence in their ability to perform self-care tasks was found to be significantly reduced from baseline to follow up (P = .045). Conclusions An Internet-based system to aid the management of diabetes appears feasible and well accepted by patients. The pilot study did not identify evidence of an impact on improving quality of life or self-efficacy in patients who used insulin pump therapy.

Abstract
Self-care is a way of helping the health service to manage the growth in long-term chronic conditions. We developed an Internet-based self-management tool for diabetes following detailed consultations with patients. The Virtual Clinic allows a patient to communicate with their health professionals, find information about their condition and share support and advice with others through peer-to-peer discussions. We conducted a test of the Virtual Clinic with five patients prior to the start of a six-month pilot study to evaluate its feasibility, acceptability and effectiveness. The test session involved an interactive computer-based element followed by a focus group to gather feedback. All five patients were positive about the Virtual Clinic. A user-centred approach to developing an Internet intervention is important to ensure that it will meet patients' needs and that they will be enthusiastic about using it.

Abstract
Less than 25% of eligible patients attend cardiac rehabilitation programs (CRP), with geographical proximity being a predominant barrier. Therefore, we undertook a pilot study to assess the feasibility and safety of using the Internet as a medium for delivery of an interactive "virtual" CRP (vCRP) to patients at a distance. Fifteen patients on the waiting list for a local hospital-based CRP were randomized to either an Internet-based vCRP or observational control. The vCRP consisted of on-line intake forms, one-on-one chat sessions with a nurse, dietitian, and exercise specialist, downloadable exercise heart rate monitoring, education and data monitoring of blood pressure, weight, and glucose. Participants were assessed for exercise capacity, risk factors, and lifestyle behaviors at baseline and at 12 weeks. Those in the vCRP logged onto the Internet-based CRP an average of 4.2 times per week. There were no adverse events in the vCRP participants. The vCRP group significantly improved their HDL-C, triglycerides, total cholesterol:HDL-C ratio, exercise capacity as assessed in metabolic equivalents, weekly physical activity, and exercise specific self-efficacy (p < 0.05). There were no significant improvements in the control group. Improvements in the vCRP group were similar to historical controls in a standard CRP. Feedback from exit interviews of the vCRP participants was unanimously positive. This Internet-based CRP resulted in clinically significant improvements in risk factors and exercise capacity similar to that of a standard CRP. The high user acceptance indicated that this program may have the potential to effectively manage patients who do not have access to traditional hospital-based CRP.

Abstract
Background The development of the Internet has created new opportunities for health care provision, including its use as a tool to aid the self-management of chronic conditions. We studied stakeholder reactions to an Internet-based “virtual clinic,” which would allow people with diabetes to communicate with their health care providers, find information about their condition, and share information and support with other users. Objective The aim of the study was to present the results of a detailed consultation with a variety of stakeholder groups in order to identify what they regard as the desirable, important, and feasible characteristics of an Internet-based intervention to aid diabetes self-management. Methods Three focus groups were conducted with 12 people with type 1 diabetes who used insulin pumps. Participants were recruited through a local diabetes clinic. One-on-one interviews were conducted with 5 health care professionals from the same clinic (2 doctors, 2 nurses, 1 dietitian) and with 1 representative of an insulin pump company. We gathered patient consensus via email on the important and useful features of Internet-based systems used for other chronic conditions (asthma, epilepsy, myalgic encephalopathy, mental health problems). A workshop to gather expert consensus on the use of information technology to improve the care of young people with diabetes was organized. Results Stakeholder groups identified the following important characteristics of an Internet-based virtual clinic: being grounded on personal needs rather than only providing general information; having the facility to communicate with, and learn from, peers; providing information on the latest developments and news in diabetes; being quick and easy to use. This paper discusses these characteristics in light of a review of the relevant literature. The development of a virtual clinic for diabetes that embodies these principles, and that is based on self-efficacy theory, is described. Conclusions Involvement of stakeholders is vital early in the development of a complex intervention. Stakeholders have clear and relevant views on what a virtual clinic system should provide, and these views can be captured and synthesized with relative ease. This work has led to the design of a system that is able to meet user needs and is currently being evaluated in a pilot study.

Abstract
Type 1 diabetes is a complex, multifactorial disease characterized by T cell-mediated autoimmune destruction of insulin-secreting pancreatic beta cells. To facilitate research in type 1 diabetes, a large-scale dynamic mathematical model of the female non-obese diabetic (NOD) mouse was developed. In this model, termed the Entelos Type 1 Diabetes PhysioLab platform, virtual NOD mice are constructed by mathematically representing components of the immune system and islet beta cell physiology important for the pathogenesis of type 1 diabetes. This report describes the scope of the platform and illustrates some of its capabilities. Specifically, using two virtual NOD mice with either average or early diabetes-onset times, we demonstrate the reproducibility of experimentally observed dynamics involved in diabetes progression, therapeutic responses to exogenous IL-10, and heterogeneity in disease onset. Additionally, we use the Type 1 Diabetes PhysioLab platform to investigate the impact of disease heterogeneity on the effectiveness of exogenous IL-10 therapy to prevent diabetes onset. Results indicate that the inability of a previously published IL-10 therapy protocol to protect NOD mice who exhibit early diabetes onset is due to high levels of pancreatic lymph node (PLN) inflammation, islet infiltration, and beta cell destruction at the time of treatment initiation. Further, simulation indicates that earlier administration of the treatment protocol can prevent NOD mice from developing diabetes by initiating treatment during the period when the disease is still sensitive to IL-10's protective function.
