  • reliability of an Interactive Computer Program for advance care planning
    Journal of Palliative Medicine, 2012
    Co-Authors: Jane R Schubart, Benjamin H. Levi, Fabian Camacho, Megan Whitehead, Elana Farace, Michael J. Green
    Abstract:

    Abstract Despite widespread efforts to promote advance directives (ADs), completion rates remain low. Making Your Wishes Known: Planning Your Medical Future (MYWK) is an Interactive Computer Program that guides individuals through the process of advance care planning, explaining health conditions and interventions that commonly involve life or death decisions, helps them articulate their values/goals, and translates users' preferences into a detailed AD document. The purpose of this study was to demonstrate that (in the absence of major life changes) the AD generated by MYWK reliably reflects an individual's values/preferences. English speakers ≥30 years old completed MYWK twice, 4 to 6 weeks apart. Reliability indices were assessed for three AD components: General Wishes; Specific Wishes for treatment; and Quality-of-Life values (QoL). Twenty-four participants completed the study. Both the Specific Wishes and QoL scales had high internal consistency in both time periods (Knuder Richardson formula 20 [KR-...

  • advance care planning for patients with als feasibility of an Interactive Computer Program
    Amyotrophic Lateral Sclerosis, 2011
    Co-Authors: Carrie Hossler, Benjamin H. Levi, Zachary Simmons, Michael J. Green
    Abstract:

    This pilot study examined whether an Interactive, Computer based decision aid can help patients with amyotrophic lateral sclerosis (ALS) engage in effective advance care planning. Individuals being treated for ALS ( 18 years old, English speaking, and without dementia) were recruited to use a decision aid and complete pre-/post-intervention measures. Seventeen individuals completed the pre-intervention questionnaires and decision aid; 16/17 (94%) completed the postintervention measures, and none reported any burden from the intervention. ‘ Overall satisfaction ’ with the decision aid was very high (mean 8.5 0.27: 1 not at all satisfi ed, 10 extremely satisfi ed), as was ‘ perceived accuracy ’ of the Computer generated advance directive in refl ecting patients ’ wishes (mean 8.6 0.27: 1 not at all accurate, 10 extremely accurate). Participants judged the ‘ amount of information ’ provided by the intervention appropriate (mean 6.8 0.38: 1 too little, 5 about right, 10 too much), and on a detailed, 12-item assessment judged the decision aid very positively (mean 4.16 0.16: 1 very dissatisfi ed, 5 very satisfi ed). The intervention prompted many participants to discuss advance care planning with loved ones and to share their Computer generated advance directive with their physician. This study demonstrates that individuals with ALS can successfully complete a Computer based decision aid for advance care planning, and suggests that this intervention can help promote effective advance care planning.

  • Development of an Interactive Computer Program for advance care planning
    Health Expectations, 2008
    Co-Authors: Michael J. Green, Benjamin H. Levi
    Abstract:

    Objective  To describe the development of an innovative, multi-media decision aid for advance care planning. Background  Advance care planning is an important way for people to articulate their wishes for medical care when they are not able to speak for themselves. Living wills and other types of advance directives are the most commonly used tools for advance care planning, but have been criticized for being vague, difficult to interpret, and inconsistent with individuals’ core beliefs and values. Results  We developed a multimedia, Computer-based decision aid for advance care planning (‘Making Your Wishes Known: Planning Your Medical Future’) to overcome many of the limitations of standard advance directive forms. This Computer Program guides individuals through the process of advance care planning, and unlike standard advance directives, provides tailored education, values clarification exercises, and a decision-making tool that translates an individual’s values and preferences into a specific medical plan that can be implemented by a health-care team. Pilot testing with 50 adult volunteers recruited from an outpatient primary care clinic showed high levels of satisfaction with the Program. Further pilot testing with 34 cancer patients indicated that the Program was perceived to be highly accurate at representing patients’ wishes. Conclusions  This paper describes the development of an innovative decision aid for advance care planning that was designed to overcome common problems with standard advance directives. Preliminary testing suggests that it is acceptable to users and is accurate.

  • effect of a Computer based decision aid on knowledge perceptions and intentions about genetic testing for breast cancer susceptibility a randomized controlled trial
    JAMA, 2004
    Co-Authors: Michael J. Green, Susan K Peterson, Maria Wagner Baker, Gregory Harper, Lois C Friedman, Wendy S Rubinstein, David T Mauger
    Abstract:

    ContextAs the availability of and demand for genetic testing for hereditary cancers increases in primary care and other clinical settings, alternative or adjunct educational methods to traditional genetic counseling will be needed.ObjectiveTo compare the effectiveness of a Computer-based decision aid with standard genetic counseling for educating women about BRCA1 and BRCA2 genetic testing.DesignRandomized controlled trial conducted from May 2000 to September 2002.Setting and ParticipantsOutpatient clinics offering cancer genetic counseling at 6 US medical centers enrolled 211 women with personal or family histories of breast cancer.InterventionsStandard one-on-one genetic counseling (n = 105) or education by a Computer Program followed by genetic counseling (n = 106).Main Outcome MeasuresParticipants' knowledge, risk perception, intention to undergo genetic testing, decisional conflict, satisfaction with decision, anxiety, and satisfaction with the intervention. Counselor group measures were administered at baseline and after counseling. Computer group measures were administered at baseline, after Computer use, and after counseling. Testing decisions were assessed at 1 and 6 months. Outcomes were analyzed by high vs low risk of carrying a BRCA1 or BRCA2 mutation.ResultsBoth groups had comparable demographics, prior Computer experience, medical literacy, and baseline knowledge of breast cancer and genetic testing, and both counseling and Computer use were rated highly. Knowledge scores increased in both groups (P<.001) regardless of risk status, and change in knowledge was greater in the Computer group compared with the counselor group (P = .03) among women at low risk of carrying a mutation. Perception of absolute risk of breast cancer decreased significantly after either intervention among all participants. Intention to undergo testing decreased significantly after either intervention among low-risk but not high-risk women. The counselor group had lower mean scores on a decisional conflict scale (P = .04) and, in low-risk women, higher mean scores on a satisfaction-with-decision scale (P = .001). Mean state anxiety scores were reduced by counseling but were within normal ranges for both groups at baseline and after either intervention, regardless of risk status.ConclusionsAn Interactive Computer Program was more effective than standard genetic counseling for increasing knowledge of breast cancer and genetic testing among women at low risk of carrying a BRCA1 or BRCA2 mutation. However, genetic counseling was more effective than the Computer at reducing women's anxiety and facilitating more accurate risk perceptions. These results suggest that this Computer Program has the potential to stand alone as an educational intervention for low-risk women but should be used as a supplement to genetic counseling for those at high risk.

  • an Interactive Computer Program can effectively educate patients about genetic testing for breast cancer susceptibility
    American Journal of Medical Genetics, 2001
    Co-Authors: Michael J. Green, Barbara B Biesecker, Aideen Mcinerney, David T Mauger, Norman Fost
    Abstract:

    As genetic testing for susceptibility to breast cancer becomes more widespread, alternative methods for educating individuals prior to testing will be needed. Our objective was to compare face-to-face education and counseling by a genetic counselor with education by an Interactive Computer Program, assessing the effects of each on knowledge of breast cancer genetics and intent to undergo genetic testing. We used a randomized, controlled trial. Seventy-two self-referred women with a first-degree relative with breast cancer received outpatient education and counseling at the Clinical Center of the National Institutes of Health (NIH). Twenty-nine received individualized counseling from a genetic counselor (counseling group), 29 received education from an Interactive Computer Program followed by individualized counseling (Computer group), and 14 were controls. Both pre- and postintervention assessment of knowledge about breast cancer genetics and intent to undergo genetic testing were measured. The control group participants correctly answered 74% of the knowledge questions; the counselor group, 92%; and the Computer group, 96% (P < .0001). Unadjusted mean knowledge scores were significantly higher in the Computer group than the counselor group (P =.048), but they were equivalent when adjusted for demographic differences (P = 0.34). Intent to undergo genetic testing was influenced by the interventions: preintervention, a majority in all groups (69%) indicated that they were likely (definitely and most likely) to undergo testing; after either intervention coupled with counseling, only 44% indicated that they were likely to do so (P =.0002; odds ratio = 2.8, 95% CI = 1.7-4.9). We concluded that a Computer Program can successfully educate patients about breast cancer susceptibility, and, along with genetic counseling, can influence patients' intentions to undergo genetic testing.

  • seisprho an Interactive Computer Program for processing and interpretation of high resolution seismic reflection profiles
    Computers & Geosciences, 2009
    Co-Authors: Luca Gasperini, G Stanghellini
    Abstract:

    SeisPrho is an Interactive Computer Program for processing and interpreting high-resolution seismic reflection profiles developed using the Delphi/Kylix multiplatform Programming environment. For this reason, it is available under Windows(TM) and Linux(TM) operating systems. The Program allows the users to handle SEG-Y data files (and other non-standard formats) carrying out a processing sequence over the data to obtain, as a final result, bitmap images of seismic sections. Some basic algorithms are implemented, including filtering and deconvolution. However, the main feature of SeisPrho is its Interactive graphic interface, which provides the user with several tools for interpreting the data, such as reflector picking and map digitizing. Moreover, the Program allows importing and geo-referencing maps and seismic profiles in the form of digital images. Trace-by-trace analysis of seismic signal and sea-bottom reflectivity is also implemented, as well as other special functions such as compilation of time-slice maps from close-spaced grids of seismic lines. SeisPrho is distributed as public domain software for non-commercial purposes by the Marine Geology division of the Istituto di Scienze Marine (ISMAR-CNR). This paper is an introduction to the Program and a preliminary guide to the users.

  • cg3tool an Interactive Computer Program to process scintrex cg 3 3m gravity data for high resolution applications
    Computers & Geosciences, 2003
    Co-Authors: Germinal Gabalda, Sylvain Bonvalot, R Hipkin
    Abstract:

    A newly developed Interactive Computer Program, CG3TOOL, has been dedicated to the processing of the gravity data acquired by the Scintrex CG-3/3M automated gravity meter. The aim of CG3TOOL is two fold: to allow for an objective evaluation of Scintrex data and to provide a higher resolution in data reductions than those computed in real time by the microprocessor-controlled instrument. The Program reads the gravity data acquired in either field or cycle mode (field surveys and continuous recordings, respectively) and then downloaded from the meter to a PC Computer. The processing tasks are divided into two successive levels. Level 1 is dedicated to the reduction of the daily data files by applying standard or accurate corrections (earth tide, instrumental drift, atmospheric pressure). The precise corrections are performed up to the microGal (µGal) level, in accordance with the specifications of high-resolution surveys. Level 2 contains a series of processing tools (including network adjustment, anomaly computation, and gravity meter calibration) that will precisely compute and adjust the gravity values with error estimates. The Interactive procedures and the Program output (plot and text files) have been designed to ease data handling and archiving as well as to provide useful information for future purposes of data interpretation or modeling. CG3TOOL was developed in a standard C language for Unix Sun workstations and uses the standard graphical and mathematical Generic Mapping Tools (GMT) free library, available from the web. The objectives and principles of the Computer Program are presented below along with corresponding examples of the main processing tasks applied to observed data.

  • teen reach outcomes from a randomized controlled trial of a tobacco reduction Program for teens seen in primary medical care
    Pediatrics, 2005
    Co-Authors: Jack F Hollis, Michael R Polen, Evelyn P Whitlock, Edward Lichtenstein, John P Mullooly, Wayne F Velicer, Colleen A Redding
    Abstract:

    Objective. To test the long-term efficacy of brief counseling plus a Computer-based tobacco intervention for teens being seen for routine medical care. Methods. Both smoking and nonsmoking teens, 14 to 17 years of age, who were being seen for routine visits were eligible for this 2-arm controlled trial. Staff members approached teens in waiting rooms of 7 large pediatric and family practice departments within a group-practice health maintenance organization. Of 3747 teens invited at ≥1 visits, 2526 (67%) consented and were randomized to tobacco intervention or brief dietary advice. The tobacco intervention was individually tailored on the basis of smoking status and stage of change. It included a 30-second clinician advice message, a 10-minute Interactive Computer Program, a 5-minute motivational interview, and up to two 10-minute telephone or in-person booster sessions. The control intervention was a 5-minute motivational intervention to promote increased consumption of fruits and vegetables. Follow-up smoking status was assessed after 1 and 2 years. Results. Abstinence rates after 2 years were significantly higher for the tobacco intervention arm, relative to the control group, in the combined sample of baseline smokers and nonsmokers (odds ratio [OR]: 1.23; 95% confidence interval [CI]: 1.03–1.47). Treatment effects were particularly strong among baseline self-described smokers (OR: 2.42; 95% CI: 1.40–4.16) but were not significant for baseline nonsmokers (OR: 1.25; 95% CI: 0.97–1.61) or for those who had “experimented” in the past month at baseline (OR: 0.95; 95% CI: 0.45–1.98). Conclusions. Brief, Computer-assisted, tobacco intervention during routine medical care increased the smoking cessation rate among self-described smokers but was less effective in preventing smoking onset.
