The Effect of Information Technology on the Information Exchange between Laboratories and Ambulatory Care Centers: A Systematic Review.

Laboratory services form an integral part of medical care in the decision-making of physicians, including those working at ambulatory care centers. Information exchange is essential between ambulatory care centers and laboratories. Inevitable errors have always existed in the exchange of such information on paper, which can be to some extent avoided by developing appropriate computer-based interfaces. Therefore, this review aimed to examine studies conducted to determine the effect of electronic communication between ambulatory care centers and laboratories. This systematic review was conducted on the basis of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies were searched in the PubMed, Embase, Cochrane, and Web of Science, and those written in English and published between 2000 and February 2019 with full texts available were selected. From a total of 3898 papers retrieved from the studied databases, 24 papers were eligible for entering this study after removing similar and nonrelated studies. Electronic exchanges between ambulatory care centers and laboratories can have numerous benefits in terms of financial, organizational, and quality. This evidence for the value of electronic communications is an important factor contributing to its local investment and adoption.

Task analysis of information technology-mediated medication management in outpatient care.

AIMS: Educating physicians in the procedural as well as cognitive skills of information technology (IT)-mediated medication management could be one of the missing links for the improvement of patient safety. We aimed to compose a framework of tasks that need to be addressed to optimize medication management in outpatient care. METHODS: Formal task analysis: decomposition of a complex task into a set of subtasks. First, we obtained a general description of the medication management process from exploratory interviews. Secondly, we interviewed experts in-depth to further define tasks and subtasks. SETTING: Outpatient care in different fields of medicine in six teaching and academic medical centres in the Netherlands and the United States. PARTICIPANTS: 20 experts. Tasks were divided up into procedural, cognitive and macrocognitive tasks and categorized into the three components of dynamic decision making. RESULTS: The medication management process consists of three components: (i) reviewing the medication situation; (ii) composing a treatment plan; and (iii) accomplishing and communicating a treatment and surveillance plan. Subtasks include multiple cognitive tasks such as composing a list of current medications and evaluating the reliability of sources, and procedural tasks such as documenting current medication. The identified macrocognitive tasks were: planning, integration of IT in workflow, managing uncertainties and responsibilities, and problem detection. CONCLUSIONS: All identified procedural, cognitive and macrocognitive skills should be included when designing education for IT-mediated medication management. The resulting framework supports the design of educational interventions to improve IT-mediated medication management in outpatient care.

Patient perspectives on test result communication in primary care: a qualitative study.

BACKGROUND: Although the number of blood tests ordered in primary care continues to increase, efficient systems for the communication of blood test results to patients are lacking. This is a concern in terms of both patient safety and patient satisfaction. AIM: To gain an understanding of patient perspectives on organisational and technological aspects of current and prospective systems for communicating laboratory test results in primary care, and the influences that impact patients' preferred methods for receiving results. DESIGN AND SETTING: Qualitative study using patient focus groups in four primary care practices in Birmingham, UK. METHOD: The primary care practices were purposively selected to ensure they varied in size, socioeconomic environment, and the default pathways they used to communicate test results. A total of 26 patients from the four practices who had had a recent blood test were recruited. Over a 6 month period in 2011, six, 1-hour focus groups were conducted at the four practices involved in the study. RESULTS: Patients expressed a preference for receiving results from the ordering GP or a clinically qualified member of staff. Suggestions for refining current systems included improved access to phlebotomy appointments, better management of patient telephone calls, and a clear, accessible protocol for the communication of results. CONCLUSION: Despite the testing and result communication process being a core activity in primary care, it was found that practices could improve their service in a number of areas. Patients described frequent delays and inconsistency in both the level of information and the method of communication, as well as dissatisfaction with non-clinical staff relaying results. Patient preferences for result communication based on their experience of current systems have produced practical suggestions to improve processes.

Patients' online access to their electronic health records and linked online services: a systematic review in primary care.

BACKGROUND: Online access to medical records by patients can potentially enhance provision of patient-centred care and improve satisfaction. However, online access and services may also prove to be an additional burden for the healthcare provider. AIM: To assess the impact of providing patients with access to their general practice electronic health records (EHR) and other EHR-linked online services on the provision, quality, and safety of health care. DESIGN AND SETTING: A systematic review was conducted that focused on all studies about online record access and transactional services in primary care. METHOD: Data sources included MEDLINE, Embase, CINAHL, Cochrane Library, EPOC, DARE, King's Fund, Nuffield Health, PsycINFO, OpenGrey (1999-2012). The literature was independently screened against detailed inclusion and exclusion criteria; independent dual data extraction was conducted, the risk of bias (RoB) assessed, and a narrative synthesis of the evidence conducted. RESULTS: A total of 176 studies were identified, 17 of which were randomised controlled trials, cohort, or cluster studies. Patients reported improved satisfaction with online access and services compared with standard provision, improved self-care, and better communication and engagement with clinicians. Safety improvements were patient-led through identifying medication errors and facilitating more use of preventive services. Provision of online record access and services resulted in a moderate increase of e-mail, no change on telephone contact, but there were variable effects on face-to-face contact. However, other tasks were necessary to sustain these services, which impacted on clinician time. There were no reports of harm or breaches in privacy. CONCLUSION: While the RoB scores suggest many of the studies were of low quality, patients using online services reported increased convenience and satisfaction. These services positively impacted on patient safety, although there were variations of record access and use by specific ethnic and socioeconomic groups. Professional concerns about privacy were unrealised and those about workload were only partly so.

Organizational complements to electronic health records in ambulatory physician performance: the role of support staff.

In industries outside healthcare, highly skilled employees enable substantial gains in productivity after adoption of information technologies. The authors explore whether the presence of highly skilled, autonomous clinical support staff is associated with higher performance among physicians with electronic health records (EHRs). Using data from a survey of general internists, the authors assessed whether physicians with EHRs were more likely to be top performers on cost and quality if they worked with nurse practitioners or physician assistants. It was found that, among physicians with EHRs, those with highly skilled, autonomous staff were far more likely to be top performing than those without such staff (OR 7.0, 95% CI 1.7 to 34.8, p=0.02). This relationship did not hold among physicians without EHRs (OR 1.0). As we begin a national push towards greater EHR adoption, it is critical to understand why some physicians gain from EHR use and others do not.

An assessment of the accuracy and availability of data in electronic patient tracking systems for patients receiving HIV treatment in central Mozambique.

BACKGROUND: Since the rapid scale-up of antiretroviral therapy (ART) programs in sub-Saharan Africa, electronic patient tracking systems (EPTS) have been deployed to respond to the growing demand for program monitoring, evaluation and reporting to governments and donors. These routinely collected data are often used in epidemiologic and operations research studies intended to improve programs. To ensure accurate reporting and good quality for research, the reliability and completeness of data systems need to be assessed and reported. We assessed the completeness and reliability of EPTS used in 16 HIV care and treatment clinics in Manica and Sofala provinces of Mozambique. METHODS: We conducted a cross-sectional study to assess the completeness and reliability of key variables in the electronic data system for patients enrolling in 16 public sector HIV treatment clinics between 1 July 2004 and 30 June 2008. Data from the electronic database was compared with data abstracted from a stratified random sample of 520 patient charts. Percent agreement, kappa scores and concordance correlation coefficients were calculated for specified variables. Percentile bootstrap confidence intervals were calculated to account for the stratified nature of our sampling. RESULTS: A total of 16,149 patients with a median age of 33 years and a median CD4 count of 151 enrolled in these 16 clinics between 1 July 2004 and 30 June 2008. The level of completeness was high for most variables with height (18.6%) and weight (11.5%) having the highest amount of missing data. The level of agreement for available data was also high with reliability statistics of 0.95 (95% CI: 0.92-0.98) for gender, 0.91 (95% CI: 0.80-1.00) for pre-ART CD4 value and 0.97 (95% CI: 0.95-0.99) for patient retention. CONCLUSIONS: Electronic patient tracking systems have been deployed to respond to the growing monitoring, evaluation and reporting requirements. In our cross-sectional study of clinics in Manica and Sofala provinces of Mozambique, we found high levels of completeness and reliability for key variables indicating that these electronic databases provided adequate data not only for monitoring and evaluation but also for research. Routine evaluations of the completeness and reliability of these databases need to occur to ensure high quality data are being used for reporting and research.

Technological resources and personnel costs required to implement an automated alert system for ambulatory physicians when patients are discharged from hospitals to home.

BACKGROUND: With the adoption of electronic medical records by medical group practices, there are opportunities to improve the quality of care for patients discharged from hospitals. However, there is little guidance for medical groups outside integrated hospital systems to automate the flow of patient information during transitions in care. OBJECTIVE: To describe the technological resources, expertise and time needed to develop an automated system providing information to ambulatory physicians when their patients are discharged from hospitals to home. DEVELOPMENT: Within a medical group practice, we developed an automated alert system that provides notification of discharges, reminders of the need for follow-up visits, drugs added during inpatient stays, and recommendations for laboratory monitoring of high-risk drugs. We tracked components of the information system required and the time spent by team members. We used USA national averages of hourly wages to estimate personnel costs. APPLICATION: Critical components of the information system are notifications of hospital discharges through an admission, discharge and transfer registration (ADT) interface, linkage to the group's scheduling system, access to information on pharmacy dispensing and lab tests, and an interface engine. Total personnel cost was $76,314. Nearly half (47%) was for 614 hours by physicians who developed content, provided overall project management, and reviewed alerts to ensure that only 'actionable' alerts would be sent. CONCLUSION: Implementing a system to provide information about hospital discharges requires strong internal informatics expertise, cooperation between facilities and ambulatory providers, development of electronic linkages, and extensive commitment of physician time.

Evaluating a scalable model for implementing electronic health records in resource-limited settings.

Current models for implementing electronic health records (EHRs) in resource-limited settings may not be scalable because they fail to address human-resource and cost constraints. This paper describes an implementation model which relies on shared responsibility between local sites and an external three-pronged support infrastructure consisting of: (1) a national technical expertise center, (2) an implementer's community, and (3) a developer's community. This model was used to implement an open-source EHR in three Ugandan HIV-clinics. Pre-post time-motion study at one site revealed that Primary Care Providers spent a third less time in direct and indirect care of patients (p<0.001) and 40% more time on personal activities (p=0.09) after EHRs implementation. Time spent by previously enrolled patients with non-clinician staff fell by half (p=0.004) and with pharmacy by 63% (p<0.001). Surveyed providers were highly satisfied with the EHRs and its support infrastructure. This model offers a viable approach for broadly implementing EHRs in resource-limited settings.

Introduction: During the last years, the use of theEmergency Services in hospitals has increased significantly,coming many of these users on their own initiative.The main aim is to determine the users’ knowledge aboutOut-Of-Hospital Emergency Services and ContinuousAssistance Point (CAP), and their motivation for comingto Hospital Emergency Services without any previous consultationat Primary Assistance.Methodology: Cross-sectional descriptive study bymeans of an ad hoc questionnaire. Representative sampleof 200 users in Emergency Services of Galdakao-UsansoloHospital over 14, who came without any medical prescriptionand were assisted in the clinic zone during April andMay 2007.Results: a) 80,51% of users knew the existence ofPrimary Assistance Emergency Services and CAP, eventhough for different reasons, decided to use HospitalEmergency Services; b) 79,89% of users belong to thenearest CAP from the reference hospital, and most ofthem to the nearest one; y c) one of the most common reasonfor using Hospital Emergency Services, despite knowingthe existence of CAP, was the prospect of more specializedassistance thanks to the technical means existingat the hospital (25,77%), as well as further personal reasons(29,38%).Conclusions: These results suggests that the users’knowledge about the existence of Out-Of-Hospital Emergency Services is wide, although, for different reasons,they don’t make use of them. All of this suggeststhat an adequate health education at Primary Assistancelevel is necessary(AU)

The impact of a multidisciplinary information technology-supported program on blood pressure control in primary care.

BACKGROUND: Hypertension is a leading mortality risk factor yet inadequately controlled in most affected subjects. Effective programs to address this problem are lacking. We hypothesized that an information technology-supported management program could help improve blood pressure (BP) control. METHODS AND RESULTS: This randomized controlled trial included 223 primary care hypertensive subjects with mean 24-hour BP >130/80 and daytime BP >135/85 mm Hg measured with ambulatory monitoring (ABPM). Intervention subjects received a BP monitor and access to an information technology-supported adherence and BP monitoring system providing nurses, pharmacists, and physicians with monthly reports. Control subjects received usual care. The mean (+/-SD) follow-up was 348 (+/-78) and 349 (+/-84) days in the intervention and control group, respectively. The primary end point of the change in the mean 24-hour ambulatory BP was consistently greater in intervention subjects for both systolic (-11.9 versus -7.1 mm Hg; P<0.001) and diastolic BP (-6.6 versus -4.5 mm Hg; P=0.007). The proportion of subjects that achieved Canadian Guideline target BP (46.0% versus 28.6%) was also greater in the intervention group (P=0.006). We observed similar BP declines for ABPM and self-recorded home BP suggesting the latter could be an alternative for confirming BP control. The intervention was associated with more physician-driven antihypertensive dose adjustments or changes in agents (P=0.03), more antihypertensive classes at study end (P=0.007), and a trend toward improved adherence measured by prescription refills (P=0.07). CONCLUSIONS: This multidisciplinary information technology-supported program that provided feedback to patients and healthcare providers significantly improved blood pressure levels in a primary care setting.

Governance for personal health records.

Personal health records (PHR) are a modern health technology with the ability to engage patients more fully in their healthcare. Despite widespread interest, there has been little discussion around PHR governance at an organizational level. We develop a governance model and compare it to the practices of some of the early PHR adopters, including hospitals and ambulatory care settings, insurers and health plans, government departments, and commercial sectors. Decision-making structures varied between organizations. Business operations were present in all groups, but patients were not represented in any of the governance structures surveyed. To improve patient-centered care, policy making for PHRs needs to include patient representation at a governance level.
