Item Dependability and Security in Medical Information System(Springer Nature, 2007) Zou, Xukai; Dai, Yuan-Shun; Doebbeling, Bradley; Qi, Mingrui; Department of Computer and Information Science, School of ScienceMedical Information Systems (MIS) help medical practice and health care significantly. Security and dependability are two increasingly important factors for MIS nowadays. In one hand, people would be willing to step into the MIS age only when their privacy and integrity can be protected and guaranteed with MIS systems. On the other hand, only secure and reliable MIS systems would provide safe and solid medical and health care service to people. In this paper, we discuss some new security and reliability technologies which are necessary for and can be integrated with existing MISs and make the systems highly secure and dependable. We also present an implemented Middleware architecture which has been integrated with the existing VISTA/CPRS system in the U.S. Department of Veterans Affairs seamlessly and transparently.Item Computerised Clinical Reminders Use in an Integrated Healthcare System(2009) Fung, Constance; Tsai, Jerry; Lulejian, Armine; Glassman, Peter; Patterson, Emily; Doebbeling, Bradley N.; Asch, StevenObjective: To examine levels of routine computerised clinical reminder use in a nationwide sample of primary care physicians and to identify factors influencing reminder use. Design: Cross-sectional using a self-administered questionnaire. Setting: The United States Veterans Health Administration. Methods: Survey responses from 461 VHA primary care physicians sampled from across the Veterans Health Administration were sampled and analysed. We asked physicians how many computerised clinical reminders they use per patient per visit and when they typically use computerised clinical reminders in their clinics. Measured physician characteristics included age, gender, year of medical degree, number of days in clinic per week, and attitudes towards computerised clinical reminders (measured on Likert-like scales). We used multivariable linear regression to determine factors associated with greater use of computerised clinical reminders per patient per visit. Results: Average computerised clinical reminder use per patient visit was 4.2 (SD = 2.5). Eightysix percent of physicians resolve reminders during the visit. In a multivariable regression model, a higher score on the team factors scale is associated with use of more reminders (increase of 0.24 reminders for each unit increase on the team factors scale, or one extra reminder for each four unit increase in the team factor scale). Working more days in clinic is associated with use of more reminders per patient visit (increase of 0.13 reminders for each extra half-day of clinic per week, or about one additional reminder for physicians working ten half-days per week versus physicians working two half-days per week). Academic facility affiliation is associated with one less reminder used per patient visit as compared with no affiliation. Conclusions: Most United States Veterans Health Administration primary care physicians use computerised clinical reminders, typically during the patient visit. Strategies to increase reminder use should focus on improving physicians’ understanding of their role in completing reminder-related tasks and improving usability for users such as physicians who work in clinic less frequently.Item The effect of provider- and workflow-focused strategies for guideline implementation on provider acceptance(2009-10) Flanagan, Mindy E.; Ramanujam, Rangaraj; Doebbeling, Bradley N.Background The effective implementation of clinical practice guidelines (CPGs) depends critically on the extent to which the strategies that are deployed for implementing the guidelines promote provider acceptance of CPGs. Such implementation strategies can be classified into two types based on whether they primarily target providers (e.g., academic detailing, grand rounds presentations) or the work context (e.g., computer reminders, modifications to forms). This study investigated the independent and joint effects of these two types of implementation strategies on provider acceptance of CPGs. Methods Surveys were mailed to a national sample of providers (primary care physicians, physician assistants, nurses, and nurse practitioners) and quality managers selected from Veterans Affairs Medical Centers (VAMCs). A total of 2,438 providers and 242 quality managers from 123 VAMCs participated. Survey items measured implementation strategies and provider acceptance (e.g., guideline-related knowledge, attitudes, and adherence) for three sets of CPGs--chronic obstructive pulmonary disease, chronic heart failure, and major depressive disorder. The relationships between implementation strategy types and provider acceptance were tested using multi-level analytic models. Results For all three CPGs, provider acceptance increased with the number of implementation strategies of either type. Moreover, the number of workflow-focused strategies compensated (contributing more strongly to provider acceptance) when few provider-focused strategies were used. Conclusion Provider acceptance of CPGs depends on the type of implementation strategies used. Implementation effectiveness can be improved by using both workflow-focused as well as provider-focused strategies.Item Provider Perceptions of Colorectal Cancer Screening Clinical Decision Support at Three Benchmark Institutions(2009-11) Saleem, Jason J.; Militello, Laura G.; Arbuckle, Nicole; Flanagan, Mindy; Haggstrom, David A.; Linder, Jeffrey A.; Doebbeling, Bradley N.Implementation of computerized clinical decision support (CDS), and its integration into workflow has not reached its potential. To better understand the use of CDS for colorectal cancer (CRC) screening at benchmark institutions for health information technology (HIT), we conducted direct observation, including opportunistic interviews of primary care providers, as well as key informant interviews and focus groups, to document current challenges to CRC screening and follow-up at clinics affiliated with the Veterans Heath Administration, Regenstrief Institute, and Partners HealthCare System. Analysis revealed six common barriers across institutions from the primary care providers’ perspective: receiving and documenting “outside” exam results, inaccuracy of the CDS, compliance issues, poor usability, lack of coordination between primary care and gastroenterology, and the need to attend to more urgent patient issues. Strategies should be developed to enhance current HIT to address these challenges and better support primary care providers and staff.Item Examining the Relationship between Clinical Decision Support and Performance Measurement(2009-11) Haggstrom, David A.; Militello, Laura G.; Arbuckle, Nicole; Flanagan, Mindy; Doebbeling, Bradley N.In concept and practice, clinical decision support (CDS) and performance measurement represent distinct approaches to organizational change, yet these two organizational processes are interrelated. We set out to better understand how the relationship between the two is perceived, as well as how they jointly influence clinical practice. To understand the use of CDS at benchmark institutions, we conducted semistructured interviews with key managers, information technology personnel, and clinical leaders during a qualitative field study. Improved performance was frequently cited as a rationale for the use of clinical reminders. Pay-for-performance efforts also appeared to provide motivation for the use of clinical reminders. Shared performance measures were associated with shared clinical reminders. The close link between clinical reminders and performance measurement causes these tools to have many of the same implementation challenges.Item The state of the art in clinical knowledge management: An inventory of tools and techniques(2010-01) Sittig, Dean F.; Wright, Adam; Simonaitis, Linas; Carpenter, James D.; Allen, George O.; Doebbeling, Bradley N.; Sirajuddin, Anwar Mohammad; Ash, Joan S.; Middleton, BlackfordPurpose To explore the need for, and use of, high-quality, collaborative, clinical knowledge management (CKM) tools and techniques to manage clinical decision support (CDS) content. Methods In order to better understand the current state of the art in CKM, we developed a survey of potential CKM tools and techniques. We conducted an exploratory study by querying a convenience sample of respondents about their use of specific practices in CKM. Results The following tools and techniques should be priorities in organizations interested in developing successful computer-based provider order entry (CPOE) and CDS implementations: (1) a multidisciplinary team responsible for creating and maintaining the clinical content; (2) an external organizational repository of clinical content with web-based viewer that allows anyone in the organization to review it; (3) an online, collaborative, interactive, Internet-based tool to facilitate content development; (4) an enterprise-wide tool to maintain the controlled clinical terminology concepts. Even organizations that have been successfully using computer-based provider order entry with advanced clinical decision support features for well over 15 years are not using all of the CKM tools or practices that we identified. Conclusions If we are to further stimulate progress in the area of clinical decision support, we must continue to develop and refine our understanding and use of advanced CKM capabilities.Item VA-INPC: Linking Department of Veterans Affairs (VA) and Indiana Network for Patient Care (INPC) data to assess surveillance testing among veterans with colorectal cancer(2010-11) Haggstrom, David A.; Rosenman, Marc; Myers, Laura J.; Teal, Evgenia; Doebbeling, Bradley N.The goal of this project was to provide empiric evidence about the benefit to US veterans and the VA of capturing data from a citywide clinical informatics network (INPC) to assess care received outside the VA. We identified 468 veterans diagnosed with colorectal cancer from 2000–2007 in the Indianapolis VA cancer registry. Electronic VA healthcare data were linked with electronic health records from the regional health information organization (RHIO) INPC; 341 matches were found. Both the VA and INPC systems were queried regarding receipt of surveillance tests. The proportion with additional data from INPC varied by test: colonoscopy (3%), CT scan/abdomen (13%), CT scan/chest (79%), carcinoembryonic antigen test (8%), and other laboratory tests (25%–53%). An incremental benefit of linking VA and INPC data was present and may increase when expanded beyond patients with a single condition. New, important information about care outside the VA is obtained through RHIO data linkage.Item Integrating Clinical Decision Support into Workflow(2011) Doebbeling, Bradley N.; Saleem, Jason; Haggstrom, David; Militello, Laura; Flanagan, Mindy; Arbuckle, Nicole; Kiess, Chris; Hoke, Shawn; Dexter, Paul; Linder, Jeff; Sarbah, Steedman; Burgo, LucillePurpose: The aims were to (1) identify barriers and facilitators related to integration of clinical decision support (CDS) into workflow and (2) develop and test CDS design alternatives. Scope: To better understand CDS integration, we studied its use in practice, focusing on CDS for colorectal cancer (CRC) screening and followup. Phase 1 involved outpatient clinics of four different systems—120 clinic staff and providers and 118 patients were observed. In Phase 2, prototyped design enhancements to the Veterans Administration’s CRC screening reminder were compared against its current reminder in a simulation experiment. Twelve providers participated. Methods: Phase 1 was a qualitative project, using key informant interviews, direct observation, opportunistic interviews, and focus groups. All data were analyzed using a coding template, based on the sociotechnical systems theory, which was modified as coding proceeded and themes emerged. Phase 2 consisted of rapid prototyping of CDS design alternatives based on Phase 1 findings and a simulation experiment to test these design changes in a within-subject comparison. Results: Very different CDS types existed across sites, yet there are common barriers: (1) lack of coordination of “outside” results and between primary and specialty care; (2) suboptimal data organization and presentation; (3) needed provider and patient education; (4) needed interface flexibility; (5) needed technological enhancements; (6) unclear role assignments; (7) organizational issues; and (8) disconnect with quality reporting. Design enhancements positively impacted usability and workflow integration but not workload. Conclusions: Effective CDS design and integration requires: (1) organizational and workflow integration; (2) integrating outside results; (3) improving data organization and presentation in a flexible interface; and (4) providing just-in time education, cognitive support, and quality reporting.Item Paper Persistence and Computer-based Workarounds with the Electronic Health Record in Primary Care(2011-09) Saleem, Jason J.; Flanagan, Mindy; Militello, Laura G.; Arbuckle, Nicole; Russ, Alissa L.; Burgo-Black, A. Lucile; Doebbeling, Bradley N.With the United States national goal and incentive program to transition from paper to electronic health records (EHRs), healthcare organizations are increasingly implementing EHRs and other related health information technology (IT). However, in institutions which have long adopted these computerized systems, such as the Veterans Health Administration, healthcare workers continue to rely on paper to complete their work. Furthermore, insufficient EHR design also results in computer-based workarounds. Using direct observation with opportunistic interviewing, we investigated the use of paper- and computer-based workarounds to the EHR with a multi-site study of 54 healthcare workers, including primary care providers, nurses, and other healthcare staff. Our analysis revealed several paper- and computer-based workarounds to the VA’s EHR. These workarounds, including clinician-designed information tools, provide evidence for how to enhance the design of the EHR to better support the needs of clinicians.Item Development of a Workflow Integration Survey (WIS) for Implementing Computerized Clinical Decision Support(2011-10) Flanagan, Mindy; Arbuckle, Nicole; Saleem, Jason J.; Militello, Laura G.; Haggstrom, David A.; Doebbeling, Bradley N.Interventions that focus on improving computerized clinical decision support (CDS) demonstrate that successful workflow integration can increase the adoption and use of CDS. However, metrics for assessing workflow integration in clinical settings are not well established. The goal of this study was to develop and validate a survey to assess the extent to which CDS is integrated into workflow. Qualitative data on CDS design, usability, and integration from four sites was collected by direct observation, interviews, and focus groups. Thematic analysis based on the sociotechnical systems theory revealed consistent themes across sites. Themes related to workflow integration included navigation, functionality, usability, and workload. Based on these themes, a brief 12-item scale to assess workflow integration was developed, refined, and validated with providers in a simulation study. To our knowledge, this is one of the first tools developed to specifically measure workflow integration of CDS.
