DEVELOPING A METHOD FOR IDENTIFYING AND REDUCING FUNCTIONAL DISCREPANCIES OF INFORMATION SYSTEMS

Currently more than half of Electronic Health Record (EHR) projects fail. Most of these failures are not due to flawed technology, but rather due to the lack of systematic considerations of human issues. Among the barriers for EHR adoption, function mismatching among users, activities, and systems is a major area that has not been systematically addressed from a human-centered perspective. A theoretical framework called Functional Framework was developed for identifying and reducing functional discrepancies among users, activities, and systems. The Functional Framework is composed of three models – the User Model, the Designer Model, and the Activity Model. The User Model was developed by conducting a survey (N = 32) that identified the functions needed and desired from the user’s perspective. The Designer Model was developed by conducting a systemic review of an Electronic Dental Record (EDR) and its functions. The Activity Model was developed using an ethnographic method called shadowing where EDR users (5 dentists, 5 dental assistants, 5 administrative personnel) were followed quietly and observed for their activities. These three models were combined to form a unified model. From the unified model the work domain ontology was developed by asking users to rate the functions (a total of 190 functions) in the unified model along the dimensions of frequency and criticality in a survey. The functional discrepancies, as indicated by the regions of the Venn diagrams formed by the three models, were consistent with the survey results, especially with user satisfaction. The survey for the Functional Framework indicated the preference of one system over the other (R=0.895). The results of this project showed that the Functional Framework provides a systematic method for identifying, evaluating, and reducing functional discrepancies among users, systems, and activities. Limitations and generalizability of the Functional Framework were discussed.

Camp For All Connection: a community health information outreach project

Purpose: The purpose of the Camp For All Connection project is to facilitate access to electronic health information resources at the Camp For All facility. Setting/Participants/Resources: Camp For All is a barrier-free camp working in partnership with organizations to enrich the lives of children and adults with chronic illnesses and disabilities and their families by providing camping and retreat experiences. The camp facility is located on 206 acres in Burton, Texas. The project partners are Texas Woman's University, Houston Academy of Medicine-Texas Medical Center Library, and Camp For All. Brief Description: The Camp For All Connection project placed Internet-connected workstations at the camp's health center in the main lodge and provided training in the use of electronic health information resources. A train-the-trainer approach was used to provide training to Camp For All staff. Results/Outcome: Project workstations are being used by health care providers and camp staff for communication purposes and to make better informed health care decisions for Camp For All campers. Evaluation Method: A post-training evaluation was administered at the end of the train-the-trainer session. In addition, a series of site visits and interviews was conducted with camp staff members involved in the project. The site visits and interviews allowed for ongoing dialog between project staff and project participants.

IMILAST: A community effort to intercompare extratropical cyclone detection and tracking algorithms: assessing method-related uncertainties

The variability of results from different automated methods of detection and tracking of extratropical cyclones is assessed in order to identify uncertainties related to the choice of method. Fifteen international teams applied their own algorithms to the same dataset - the period 1989-2009 of interim European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERAInterim) data. This experiment is part of the community project Intercomparison of Mid Latitude Storm Diagnostics (IMILAST; see www.proclim.ch/imilast/index.html). The spread of results for cyclone frequency, intensity, life cycle, and track location is presented to illustrate the impact of using different methods. Globally, methods agree well for geographical distribution in large oceanic regions, interannual variability of cyclone numbers, geographical patterns of strong trends, and distribution shape for many life cycle characteristics. In contrast, the largest disparities exist for the total numbers of cyclones, the detection of weak cyclones, and distribution in some densely populated regions. Consistency between methods is better for strong cyclones than for shallow ones. Two case studies of relatively large, intense cyclones reveal that the identification of the most intense part of the life cycle of these events is robust between methods, but considerable differences exist during the development and the dissolution phases.

Anatomic pathways of peripancreatic fluid draining to mediastinum in recurrent acute pancreatitis: visible human project and CT study

BACKGROUND In past reports, researchers have seldom attached importance to achievements in transforming digital anatomy to radiological diagnosis. However, investigators have been able to illustrate communication relationships in the retroperitoneal space by drawing potential routes in computerized tomography (CT) images or a virtual anatomical atlas. We established a new imaging anatomy research method for comparisons of the communication relationships of the retroperitoneal space in combination with the Visible Human Project and CT images. Specifically, the anatomic pathways of peripancreatic fluid extension to the mediastinum that may potentially transform into fistulas were studied. METHODS We explored potential pathways to the mediastinum based on American and Chinese Visible Human Project datasets. These drainage pathways to the mediastinum were confirmed or corrected in CT images of 51 patients with recurrent acute pancreatitis in 2011. We also investigated whether additional routes to the mediastinum were displayed in CT images that were not in Visible Human Project images. PRINCIPAL FINDINGS All hypothesized routes to the mediastinum displayed in Visible Human Project images, except for routes from the retromesenteric plane to the bilateral retrorenal plane across the bilateral fascial trifurcation and further to the retrocrural space via the aortic hiatus, were confirmed in CT images. In addition, route 13 via the narrow space between the left costal and crural diaphragm into the retrocrural space was demonstrated for the first time in CT images. CONCLUSION This type of exploration model related to imaging anatomy may be used to support research on the communication relationships of abdominal spaces, mediastinal spaces, cervical fascial spaces and other areas of the body.

Self-burning – A rare suicide method in switzerland and other industrialised nations – A review

News items reporting self-immolation by Tibetans have been on the increase in recent years. After examining the corpse of a Swiss man who had committed suicide by deliberate self-burning, we wondered how often this occurs in Switzerland. The Federal Statistics Office (FSO) does not register self-burning specifically so no official national data on this form of suicide are available. However, we had access to the data from a Swiss National Science Foundation (SNSF) project Suicides in Switzerland between 2000 and 2010, which collected information on all (4885) cases of suicide investigated by the various institutes of forensic medicine. From this data pool we extracted 50 cases (1.02%) of suicide by selfburning, in order to determine the details and to identify the possible reasons for choosing this method. To look at our results in the light of studies from other countries, we searched the literature for studies that had also retrospectively examined suicide by self-immolation based on forensic records. Our results showed that, on the whole, personal aspects of selfburning in Switzerland do not differ from those in other industrialised nations. Some data, including religious and sociocultural background, were unfortunately missing – not only from our study but also from the similar ones. In our opinion, the most important prevention strategy is to make healthcare professionals more aware of this rare method of suicide.

[Pilot Project: Improved Lung Deposition via a New Nasal Inhalation Procedure].

INTRODUCTION Inhaled drugs can only be effective if they reach the middle and small airways. This study introduces a system that combines a trans-nasal application of aerosols with noninvasive pressure support ventilation. METHODS In a pilot study, 7 COPD patients with GOLD stages II and III inhaled a radiolabeled marker dissolved in water via a trans-nasal route. The mean aerosol particle size was 5.5 µm. Each patient took part in two inhalation sessions that included two application methods and were at least 70 hours apart. During the first session ("passive method"), the patient inhaled the aerosol through an open tube system. The second session ("active method") included pressure support ventilation during the inhalation process. A gamma camera and planar scintigraphy was used to determine the distribution of aerosol particles in the patient's body and lung. RESULTS The pressure supported inhalation ("active method") results in an increased aerosol lung deposition compared to the passive method. Above all, we could demonstrate deposition in the lung periphery with relatively large aerosol particles (5.5 µm). DISCUSSION The results prove that the combination of trans-nasal inhalation with noninvasive pressure support ventilation leads to significantly increased particle deposition in the lung.

The sequence comparison index: A novel method for comparing proteins and proteomes

Historically morphological features were used as the primary means to classify organisms. However, the age of molecular genetics has allowed us to approach this field from the perspective of the organism's genetic code. Early work used highly conserved sequences, such as ribosomal RNA. The increasing number of complete genomes in the public data repositories provides the opportunity to look not only at a single gene, but at organisms' entire parts list. ^ Here the Sequence Comparison Index (SCI) and the Organism Comparison Index (OCI), algorithms and methods to compare proteins and proteomes, are presented. The complete proteomes of 104 sequenced organisms were compared. Over 280 million full Smith-Waterman alignments were performed on sequence pairs which had a reasonable expectation of being related. From these alignments a whole proteome phylogenetic tree was constructed. This method was also used to compare the small subunit (SSU) rRNA from each organism and a tree constructed from these results. The SSU rRNA tree by the SCI/OCI method looks very much like accepted SSU rRNA trees from sources such as the Ribosomal Database Project, thus validating the method. The SCI/OCI proteome tree showed a number of small but significant differences when compared to the SSU rRNA tree and proteome trees constructed by other methods. Horizontal gene transfer does not appear to affect the SCI/OCI trees until the transferred genes make up a large portion of the proteome. ^ As part of this work, the Database of Related Local Alignments (DaRLA) was created and contains over 81 million rows of sequence alignment information. DaRLA, while primarily used to build the whole proteome trees, can also be applied shared gene content analysis, gene order analysis, and creating individual protein trees. ^ Finally, the standard BLAST method for analyzing shared gene content was compared to the SCI method using 4 spirochetes. The SCI system performed flawlessly, finding all proteins from one organism against itself and finding all the ribosomal proteins between organisms. The BLAST system missed some proteins from its respective organism and failed to detect small ribosomal proteins between organisms. ^

Instrumental variable method for the causal relationship between soluble receptor for advanced glycation end-products (sRAGE) and risk of pancreatic cancer

This thesis project is motivated by the potential problem of using observational data to draw inferences about a causal relationship in observational epidemiology research when controlled randomization is not applicable. Instrumental variable (IV) method is one of the statistical tools to overcome this problem. Mendelian randomization study uses genetic variants as IVs in genetic association study. In this thesis, the IV method, as well as standard logistic and linear regression models, is used to investigate the causal association between risk of pancreatic cancer and the circulating levels of soluble receptor for advanced glycation end-products (sRAGE). Higher levels of serum sRAGE were found to be associated with a lower risk of pancreatic cancer in a previous observational study (255 cases and 485 controls). However, such a novel association may be biased by unknown confounding factors. In a case-control study, we aimed to use the IV approach to confirm or refute this observation in a subset of study subjects for whom the genotyping data were available (178 cases and 177 controls). Two-stage IV method using generalized method of moments-structural mean models (GMM-SMM) was conducted and the relative risk (RR) was calculated. In the first stage analysis, we found that the single nucleotide polymorphism (SNP) rs2070600 of the receptor for advanced glycation end-products (AGER) gene meets all three general assumptions for a genetic IV in examining the causal association between sRAGE and risk of pancreatic cancer. The variant allele of SNP rs2070600 of the AGER gene was associated with lower levels of sRAGE, and it was neither associated with risk of pancreatic cancer, nor with the confounding factors. It was a potential strong IV (F statistic = 29.2). However, in the second stage analysis, the GMM-SMM model failed to converge due to non- concaveness probably because of the small sample size. Therefore, the IV analysis could not support the causality of the association between serum sRAGE levels and risk of pancreatic cancer. Nevertheless, these analyses suggest that rs2070600 was a potentially good genetic IV for testing the causality between the risk of pancreatic cancer and sRAGE levels. A larger sample size is required to conduct a credible IV analysis.^

Adherence to HIV /AIDS therapies among low -literacy populations: The ALP project

Adherence to HIV/AIDS therapies has been an important health problem since the early 1980s when AZT was first prescribed as a therapy for HIV/AIDS. It became particularly important between 1995 and 1997 with the advent of protease inhibitors (Chesney, Ickovics, Hecht, Sikipa, & Rabkin J., 1999) and became even more significant as persons with HIV/AIDS began to develop resistance to medications. Low-literacy populations have poorer health (Brez & Taylor, 1997) and higher AIDS rates (Simon, Hu, Diaz, & Kerndt, 1995), than their higher literacy counterparts due to delayed treatment (Baker, Parker, Williams, Clark, & Nurss, 1997), shame of literacy skills (Parikh, 1996), and poor access to care (Williams, et al., 1995). Poorer health and higher AIDS rates can also be attributed to poor patient-provider relationships (Crespo-Fierro, 1997; Eldred, Wu, Chaisson, & Moore, 1998) to a poorer understanding of medical protocols (Murphy, 1997), and inadequate patient education (Ungvarski, 1997; Davis, Michielutte, Askov, Williams, & Weiss, 1998, Doak, Doak, & Root, 1996). ^ The ALP intervention was developed for HIV positive low-literacy populations of African American women in Houston, Texas. The intervention was based on a needs assessment, using the PRECEDE model, an innovative process referred to as Intervention Mapping, and validated using formative evaluation methods with 54 individuals. The needs assessment resulted in a list of behavioral, environmental, predisposing, enabling, and reinforcing determinants of adherence. The Intervention Mapping framework was used to refine these determinants and develop a list of objectives describing what must be learned or changed to for the target population to adhere to HIV/AIDS therapies. Methods and strategies, were developed using theoretical constructs from the Health Belief Model (Rosenstock, 1974) and Social Cognitive Theory (Bandura, 1986). These theories, empirical evidence, and information from the target population indicated that perceived susceptibility, perceived severity, outcome expectations, and self-efficacy were important and changeable determinants of adherence to HIV/AIDS therapies for this population. ^ These components were brought together in the form of a theory-based color cartoon book and 10-minute cassette tape. The book was developed for people with 2.9 years of U.S. education as measured with the Flesch-Kincaid Grade Level method and the script was recorded onto a cassette tape to make it suitable for populations with even lower-literacy skills. A formative evaluation was conducted to ensure that the content and structure were accurate, clear, realistic, readable, appropriate, and likely to be used as intended. ^

Saving Young Lives: Pathfinder International’s Youth-Friendly Postabortion Care Project

As many as 2.5 million adolescent women seek abortion each year, and nearly 70,000 women die from complications related to unsafe abortion, of which almost half are women under the age of 25. A further 5 million women suffer disability due to unsafe abortion yearly. In most developing countries, abortion is legally restricted or highly inaccessible, which leads young women to seek services from unskilled practitioners often leading to incomplete, septic abortions and massive bleeding, which can result in permanent injury, infertility, and death. Based on our deeply held belief that all people, including adolescents, have a right to sexual and reproductive health services and the importance of addressing adolescent needs within Postabortion Care (PAC) services, Pathfinder used private funds to initiate a Youth-Friendly Postabortion Care (YFPAC) program in eight sub-Saharan African countries. Implemented between June 2007 and May 2008, the YFPAC program offered an opportunity to apply the PAC Consortium’s Technical Guidance on Youth-Friendly PAC, generating promising approaches and lessons learned. The goal of the YFPAC initiative was to increase access to PAC services that are responsive to adolescent needs in sub-Saharan Africa. While outcomes varied according to the country, the overall outcomes included: Increased community support for services and activities that prevent unwanted pregnancy, decreased stigma around abortion, and awareness of the issue of unsafe abortion among adolescent women: 311 peer educators reached almost 17,487 youth and other community members; 171 stakeholders (e.g., religious and traditional leaders, health officials, and local government officials) were sensitized on YFPAC, resulting in a positive shift in communities’ attitudes toward youth in need of PAC services. 125 service providers were trained to deliver YFPAC services and three doctors in Ghana were provided with a technical update on YFPAC. YFPAC services are available in Angola, Ghana, Nigeria, Mozambique, Tanzania, Uganda, Ethiopia, and Kenya. Pathfinder introduced YFPAC services into 25 facilities (in 27 service delivery points), and provided more than 3,800 clients with YFPAC services throughout the eight countries. The number of adolescent PAC clients seen at the project facilities increased— 710 clients were seen in the first quarter, 1,144 were seen in the fourth. The number of adolescent PAC clients who adopt a contraceptive method to prevent future unintended pregnancies has increased. Statistics show an average postabortion contraceptive acceptance of 69%, with the highest acceptance being 83% and the lowest being 44%. Evidence-based approaches, tools, and lessons learned are being disseminated and used for scale-up or replication of YFPAC interventions.
