The effective use of information technology (IT) is a crucial component for the delivery of effective services in health care. Current approaches to medical informatics (MI) research have significantly contributed to the success of IT use in health care but important challenges remain to be addressed. We believe that expanding the multi-disciplinary basis for MI research is important to meeting these research challenges. In this paper, we outline theories and methods used in information systems (IS) research that we believe can inform our understanding of health care IT applications and outcomes. To do so, we discuss some general differences in the focus and methods of MI and IS research to identify broad opportunities. We then review conceptual and methodological approaches in IS that have been applied in health care IT research. These include: technology-use mediation, collaborative work, genre theory, interpretive research, action research, and modeling. Examples of these theories and methods in healthcare IS research are illustrated.
We are amending our regulations to provide that we will suspend your disability benefits before we make a determination during a continuing disability review (CDR) under title II and title XVI of the Social Security Act (the Act) when you fail to comply with our request for necessary information. Should you remain non-compliant for a period of one year following your suspension, we will then terminate your disability benefits. Although our current title XVI regulations generally provide for the termination of payments after 12 months of suspension, we are amending our regulations by adding this policy to our title II regulations and by restating it in the title XVI CDR regulatory provisions.
BACKGROUND: The Consortium on the Genetics of Schizophrenia (COGS) is an ongoing, National Institute of Mental Health-funded, 7-site collaboration investigating the occurrence and genetic architecture of quantitative endophenotypes related to schizophrenia. The purpose of this article is to provide a description of the COGS structure and methods, including participant recruitment and assessment. METHODS: The hypothesis-driven recruitment strategy ascertains families that include a proband with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of schizophrenia, and at least one unaffected full sibling available for genotyping and endophenotyping, along with parents available for genotyping and (optional depending on age) endophenotyping. The family structure is selected to provide contrast in quantitative endophenotypic traits and thus to maximize the power of the planned genetic analyses. Probands are recruited from many sources including clinician referrals, local National Alliance for the Mentally Ill chapters, and advertising via the media. All participants undergo a standardized protocol that includes clinical characterization, a blood draw for genotyping, and endophenotype assessments (P50 suppression, prepulse inhibition, antisaccade performance, continuous performance tasks, letter-number span, verbal memory, and a computerized neurocognitive battery). Investigators participate in weekly teleconferences to coordinate and evaluate recruitment, clinical assessment, endophenotyping, and continuous quality control of data gathering and analyses. Data integrity is maintained through use of a highly quality-assured, centralized web-based database. RESULTS: As of February 2006, 355 families have been enrolled and 688 participants have been endophenotyped, including schizophrenia probands (n = 154, M:F = 110:44), first-degree biological relatives (n = 343, M:F = 151:192), and community comparison subjects (n = 191, M:F = 81:110). DISCUSSION: Successful multisite genetics collaborations must institute standardized methodological criteria for assessment and recruitment that are clearly defined, well communicated, and uniformly applied. In parallel, studies utilizing endophenotypes require strict adherence to criteria for cross-site data acquisition, equipment calibration and testing and software equivalence, and continuous quality assurance for many measures obtained across sites. This report describes methods and presents the structure of the COGS as a model of multisite endophenotype genetic studies. It also provides demographic information after the first 2 years of data collection on a sample for whom the behavioral data and genetics of endophenotype performance will be fully characterized in future articles. Some issues discussed in the reviews that follow reflect the challenges of evaluating endophenotypes in studies of the genetic architecture of endophenotypes in schizophrenia.
