From Caregiver to Computer Geek: The Design of a Web Resource for Novice Clinical Informaticians

Introduction: Throughout the United States, there are massive initiatives in place to reform healthcare through the implementation of electronic health records. The goals are to improve patient care through improved access to records, the improvement of business and reimbursement processes, streamlining of clinician workflows for increased efficiency, and reducing the variability in the delivery of patient care.

Physician coding for mental illness reimbursement and the need for mental health parity

Many patients with anxiety and depression initially seek treatment from their primary care physicians. Changes in insurance coverage and current mental parity laws, make reimbursement for services a problem. This has led to a coding dilemma for physicians seeking payment for their services. This study seeks to determine first the frequency at which primary care physicians use alternative coding, and secondly, if physicians would change their coding practices, provided reimbursement was assured through changes in mental parity laws. A mail survey was sent to 260 randomly selected primary care physicians, who are family practice, internal medicine, and general practice physicians, and members of the Harris County Medical Society. The survey evaluated the physicians' demographics, the number of patients with psychiatric disorders seen by primary care physicians, the frequency with which physicians used alternative coding, and if mental parity laws changed, the rate at which physicians would use a psychiatric illness diagnosis as the primary diagnostic code. The overall response rate was 23%. Only 47 of the 59 physicians, who responded, qualified for the study and of those 45% used a psychiatric disorder to diagnose patients with a primary psychiatric disorder, 47% used a somatic/symptom disorder, and 8% used a medical diagnosis. From the physicians who would not use a psychiatric diagnosis as a primary ICD-9 code, 88% were afraid of not being reimbursed and 12% were worried about stigma or jeopardizing insurability. If payment were assured using a psychiatric diagnostic code, 81% physicians would use a psychiatric diagnosis as the primary diagnostic code. However, 19% would use an alternative diagnostic code in fear of stigmatizing and/or jeopardizing patients' insurability. Although the sample size of the study design was adequate, our survey did not have an ideal response rate, and no significant correlation was observed. However, it is evident that reimbursement for mental illness continues to be a problem for primary care physicians. The reformation of mental parity laws is necessary to ensure that patients receive mental health services and that primary care physicians are reimbursed. Despite the possibility of improved mental parity legislation, some physicians are still hesitant to assign patients with a mental illness diagnosis, due to the associated stigma, which still plays a role in today's society. ^

An assessment of differences in pediatric dental services provided for a Medicaid population when compared to a federally subsidized (military) clinic

Reimbursement for dental services performed for children receiving Medicaid is reimbursed per service while dental treatment for military dependents provided at a military installation is neither directly reimbursable to those providing the care nor billed to those receiving the care. The purpose of this study was to compare pediatric dental services provided for a Medicaid population to a federally subsidized military facility to compare treatment choices and subsequent costs of care. It was hypothesized that differences in dental procedures for Medicaid and military dependent children would exist based upon treatment philosophy and payment method. A total of 240 records were reviewed for this study, consisting of 120 Medicaid patients at the University of Texas Health Science Center at San Antonio (UTHSCSA) and 120 military dependents at Wilford Hall Medical Center (WHMC), Lackland Air Force Base, San Antonio. Demographic data and treatment information were abstracted for children receiving dental treatment under general anesthesia between 2002 and 2006. Data was analyzed using the Wilcoxon rank sum test, Kruskal-Wallis test, and Fisher's exact test. The Medicaid recipients treated at UTHSCSA were younger than patients at WHMC (40.2 vs. 49.8 months, p<.001). The university also treated significantly more Hispanic children than WHMC (78.3% vs. 30.0%, p<.001). Children at UTHSCSA had a mean of 9.5 decayed teeth and were treated with 2.3 composite fillings, 0 amalgam fillings, 5.6 stainless steel crowns, 1.1 pulp therapies, 1.6 extractions, and 1.0 sealant. Children at WHMC had a mean of 8.7 decayed teeth and were treated with 1.4 composite fillings, 0.9 amalgam fillings, 5.6 stainless steel crowns, 1.7 pulp therapies, 0.9 extractions, and 2.1 sealants. The means of decayed teeth, total fillings, and stainless steel crowns were not statistically different. UTHSCSA provided more composite fillings (p<.001), fewer amalgam fillings (p<.001), fewer pulp therapies (p <.001), more extractions (p=.01), and fewer sealants (p<.001) when compared to WHMC. Age and gender did not effect decay rates, but those of Hispanic ethnicity did experience more decay than non-Hispanics (9.5 vs. 8.6, p=.02). Based upon Texas Medicaid reimbursement rates from 2006, the cost for dental treatment at both sites was approximately $650 per child. The results of this study do not support the hypothesis that Medicaid providers provide less conservative therapies, which would be more costly, care when compared to a military treatment center. ^

Efforts of hospital system wound care teams to reduce hospital acquired pressure ulcers

New reimbursement policies developed by the Centers for Medicare and Medicaid Services (CMS) are revolutionizing the health care landscape in America. The policies focus on clinical quality and patient outcomes. As part of the new policies, certain hospital acquired conditions have been identified by Medicare as "reasonably preventable". Beginning October 1, 2008, Medicare will no longer reimburse hospitals for these conditions developed after admission, pressure ulcers are among the most common of these conditions.^ In this practice-based culminating experience the objective was to provide a practical account of the process of program development, implementation and evaluation in a public health setting. In order to decrease the incidence of pressure ulcers, the program development team of the hospital system developed a comprehensive pressure ulcer prevention program using a "bundled" approach. The pressure ulcer prevention bundle was based on research supported by the Institute for Healthcare Improvement, and addressed key areas of clinical vulnerability for pressure ulcer development. The bundle consisted of clinical processes, policies, forms, and resources designed to proactively identify patients at risk for pressure ulcer development. Each element of the bundle was evaluated to ensure ease of integration into the workflow of nurses and clinical ancillary staff. Continued monitoring of pressure ulcer incidence rates will provide statistical validation of the impact of the prevention bundle. ^

Texas dentists' attitudes and activity level since the change in Medicaid reimbursement rates

Purpose. The purpose of this study was to determine if the change in Medicaid reimbursements in Texas affected the activity level of the enrolled providers or changed the attitudes of dentists towards Medicaid. ^ Methods. A letter with instructions for completing a survey online was sent to a random sample of 415 general and 325 pediatric dentists (500 dentists originally sampled by Blackwelder plus 240 additional dentists). The survey consisted of 27 questions about Medicaid. ^ Results. Surveys from 98 (13.2%) of dentists were collected, with 57 (17.5%) from pediatric dentists and 37(9%) from general dentists. Our results were compared to the study by Blackwelder et al, which reported attitudes of Texas dentists toward the Medicaid program prior to the reimbursement change. Our data indicates an increase in Medicaid activity among enrolled providers (58.6% activity to 94.8% activity) with greater percent change among pediatric dentists (61.8% to 97.5%) compared to general dentists (53.3% to 80%). Also, the proportion of enrolled active Medicaid providers spending greater then 10% of their time with Medicaid has increased (76.9% to 87.3%). Furthermore, pediatric dentists spending greater then 50% of their time with Medicaid increased from 30.9% to 38.5%, and general dentists from 18.4% to 37.5%. Perceived barriers appear to be similar to past studies. ^ Conclusions. Our survey indicated the change in Medicaid reimbursements did increase the activity level of enrolled Medicaid providers and it appears that active Medicaid providers are spending more time with Medicaid patients.^

Use of intranet and other interventions to increase influenza vaccination among health care workers

Influenza (the flu) is a serious respiratory illness that can cause severe complications, often leading to hospitalization and even death. Influenza epidemics occur in most countries every year, usually during the winter months. Despite recommendations from the Centers for Disease Control and Prevention (CDC) and efforts by health care institutions across the United States, influenza vaccination rates among health care workers in the United States remain low. How to increase the number of vaccinated health care workers is an important public health question and is examined in two journal articles included here. ^ The first journal article evaluates the effectiveness of an Intranet intervention in increasing the proportion of health care workers (HCWs) who received influenza vaccination. Hospital employees were required go to the hospital's Intranet and select "vaccine received," "contraindicated," or "declined" from the online questionnaire. Declining employees automatically received an online pop-up window with education about vaccination; managers were provided feedback on employees' participation rates via e-mail messages. Employees were reminded of the Intranet requirement in articles in the employee newsletter and on the hospital's Intranet. Reminders about the Intranet questionnaire were provided through managers and newsletters to the HCWs. Fewer than half the employees (43.7%) completed the online questionnaire. Yet the hospital witnessed a statistically significant increase in the percentage of employees who received the flu vaccine at the hospital – 48.5% in the 2008-09 season as compared to 36.5%, 38.5% and 29.8% in the previous three years (P < 0.05). ^ The second article assesses current interventions employed by hospitals, health systems and nursing homes to determine which policies have been the most effective in boosting vaccination rates among American health care workers. A systematic review of research published between January 1994 and March 2010 suggests that education is necessary but not usually sufficient to increase vaccine uptake. Education about the flu and flu vaccines is most effective when complemented with easy access and making the vaccine free, although this combination may not be sufficient to achieve the desired vaccination levels among HCWs. The findings point toward adding incentives for HCWs to get vaccinated and requiring them to record their vaccination status on a declination/consent form – either written or electronic. ^ Based on these findings, American health care organizations, such as hospitals, nursing homes, and long-term care facilities, should consider using online declination forms as a method for increasing influenza vaccination rates among their employees. These online forms should be used in conjunction with other policies, including free vaccine, mobile distribution and incentives. ^ To further spur health care organizations to adopt policies and practices that will raise influenza vaccination rates among employees, The Joint Commission – an independent, not-for- profit organization that accredits and certifies more than 17,000 health care organizations and programs in the United States – should consider altering its standards. Currently, The Joint Commission does not require signed declination forms from employees who eschew vaccination; it only echoes the CDC's recommendations: "Health care facilities should require personnel who refuse vaccination to complete a declination form." Because participation in Joint Commission accreditation is required for Medicare reimbursement, action taken by the Joint Commission to require interventions such as mandatory declination/consent forms might result in immediate action by health care organizations to follow these new standards and lead to higher vaccination rates among HCWs.^ 1“Frequently Asked Questions for H1N1 and Seasonal Influenza.” The Joint Commission - Infection Control: http://www.jointcommission.org/PatientSafety/InfectionControl/h1n1_faq.htm. ^

The SanaViz: Human Centered Geovisualization to facilitate visual exploration of Public Health data

These three manuscripts are presented as a PhD dissertation for the study of using GeoVis application to evaluate telehealth programs. The primary reason of this research was to understand how the GeoVis applications can be designed and developed using combined approaches of HC approach and cognitive fit theory and in terms utilized to evaluate telehealth program in Brazil. First manuscript The first manuscript in this dissertation presented a background about the use of GeoVisualization to facilitate visual exploration of public health data. The manuscript covered the existing challenges that were associated with an adoption of existing GeoVis applications. The manuscript combines the principles of Human Centered approach and Cognitive Fit Theory and a framework using a combination of these approaches is developed that lays the foundation of this research. The framework is then utilized to propose the design, development and evaluation of “the SanaViz” to evaluate telehealth data in Brazil, as a proof of concept. Second manuscript The second manuscript is a methods paper that describes the approaches that can be employed to design and develop “the SanaViz” based on the proposed framework. By defining the various elements of the HC approach and CFT, a mixed methods approach is utilized for the card sorting and sketching techniques. A representative sample of 20 study participants currently involved in the telehealth program at the NUTES telehealth center at UFPE, Recife, Brazil was enrolled. The findings of this manuscript helped us understand the needs of the diverse group of telehealth users, the tasks that they perform and helped us determine the essential features that might be necessary to be included in the proposed GeoVis application “the SanaViz”. Third manuscript The third manuscript involved mix- methods approach to compare the effectiveness and usefulness of the HC GeoVis application “the SanaViz” against a conventional GeoVis application “Instant Atlas”. The same group of 20 study participants who had earlier participated during Aim 2 was enrolled and a combination of quantitative and qualitative assessments was done. Effectiveness was gauged by the time that the participants took to complete the tasks using both the GeoVis applications, the ease with which they completed the tasks and the number of attempts that were taken to complete each task. Usefulness was assessed by System Usability Scale (SUS), a validated questionnaire tested in prior studies. In-depth interviews were conducted to gather opinions about both the GeoVis applications. This manuscript helped us in the demonstration of the usefulness and effectiveness of HC GeoVis applications to facilitate visual exploration of telehealth data, as a proof of concept. Together, these three manuscripts represent challenges of combining principles of Human Centered approach, Cognitive Fit Theory to design and develop GeoVis applications as a method to evaluate Telehealth data. To our knowledge, this is the first study to explore the usefulness and effectiveness of GeoVis to facilitate visual exploration of telehealth data. The results of the research enabled us to develop a framework for the design and development of GeoVis applications related to the areas of public health and especially telehealth. The results of our study showed that the varied users were involved with the telehealth program and the tasks that they performed. Further it enabled us to identify the components that might be essential to be included in these GeoVis applications. The results of our research answered the following questions; (a) Telehealth users vary in their level of understanding about GeoVis (b) Interaction features such as zooming, sorting, and linking and multiple views and representation features such as bar chart and choropleth maps were considered the most essential features of the GeoVis applications. (c) Comparing and sorting were two important tasks that the telehealth users would perform for exploratory data analysis. (d) A HC GeoVis prototype application is more effective and useful for exploration of telehealth data than a conventional GeoVis application. Future studies should be done to incorporate the proposed HC GeoVis framework to enable comprehensive assessment of the users and the tasks they perform to identify the features that might be necessary to be a part of the GeoVis applications. The results of this study demonstrate a novel approach to comprehensively and systematically enhance the evaluation of telehealth programs using the proposed GeoVis Framework.
