Adolescent Participation in HPV Vaccine Clinical Trials: Are Parents Willing?
Erves JC, Mayo-Gamble TL, Hull PC, Duke L, Miller ST
(2017) J Community Health 42: 894-901
MeSH Terms: Adolescent, Clinical Trials as Topic, Health Knowledge, Attitudes, Practice, Humans, Papillomavirus Vaccines, Parents, Patient Acceptance of Health Care, Vaccination
Show Abstract · Added March 27, 2017
Approximately one-quarter of human papillomavirus (HPV) infections are acquired by adolescents, with a higher burden among racial/ethnic minorities. However, racial/ethnic minorities have been underrepresented in previous HPV vaccine trials. Ongoing and future HPV vaccine optimization trials would benefit from racially- and ethnically-diverse sample of adolescent trial participants. This study examined factors influencing parental willingness to consent to their adolescents' participation in HPV vaccine clinical trials and tested for possible racial differences. A convenience sample of parents of adolescents (N = 256) completed a cross-sectional survey. Chi square analyses were used to assess racial differences in parental HPV vaccine awareness and intentions and willingness to consent to their child participating in an HPV vaccine clinical trial. Ordinal logistic regression was used to identify factors associated with willingness. Approximately 47% of parents were willing to allow their adolescent to participate in HPV vaccine clinical trials (30.7% African American and 48.3% Caucasian, p = .081). African Americans had lower HPV vaccine awareness (p = .006) but not lower intentions to vaccinate (p = .086). Parental willingness was positively associated with the following variables: Child's age (p < .039), Perceived Advantages of HPV Vaccination for Adolescents (p = .002), Parental Trust in Medical Researchers (p < .001), and Level of Ease in Understanding Clinical Trial Information (p = .010). Educating parents about the advantages of HPV vaccines for younger adolescents using low-literacy educational materials and building trust between parents and researchers may increase parental willingness to consent to adolescent participation in HPV vaccine clinical trials.

'It means everyone should know their status': exploring lay conceptions of sickle cell trait and sickle cell trait screening among African Americans within middle reproductive age.
Mayo-Gamble TL, Barnes PA, Cunningham Erves J, Middlestadt SE, Lin HC
(2018) Ethn Health 23: 813-829
MeSH Terms: Adult, African Americans, Anemia, Sickle Cell, Decision Making, Female, Health Knowledge, Attitudes, Practice, Humans, Indiana, Male, Mass Screening, Reproductive Health, Sickle Cell Trait, Surveys and Questionnaires
Show Abstract · Added March 18, 2017
OBJECTIVE - This study examined the meaning of sickle cell trait and sickle cell trait screening from the lay perspective of African Americans.
DESIGN AND METHODS - African Americans (N = 300), ages 18-35 and unaware of their sickle cell trait status, completed two open-ended questions from a larger survey. One question asked for their understanding of sickle cell trait; the other asked for their understanding of sickle cell trait screening. Content analysis occurred in two phases: (1) In vivo and holistic coding; and (2) focused coding.
RESULTS - Four categories emerged illustrating lay conceptions of sickle cell trait; (1) Perceived as an illness; (2) Perceived recognition of the inheritance pattern of sickle cell trait; (3) Perceived lack of knowledge of sickle cell trait; and (4) Perceived importance of sickle cell trait. Five categories emerged illustrating lay conceptions for sickle cell trait screening: (1) Perceived recognition that screening means getting tested for sickle cell trait; (2) Perceived lack of knowledge of sickle cell trait screening; (3) Perceived health benefit of sickle cell trait screening; (4) Perceived importance of sickle cell trait screening; and (5) Perceived barriers to sickle cell trait screening.
CONCLUSIONS - Sickle cell trait and sickle cell trait screening are concepts that are both regarded as important among this high-risk population. However, there is still misunderstanding concerning the hereditary nature and reproductive implications of sickle cell trait. Interventions seeking to improve communication on the need for sickle cell trait screening should begin by identifying what the population at large understands, knows and/or believes to improve their ability to make informed health decisions.

Using an Implementation Research Framework to Identify Potential Facilitators and Barriers of an Intervention to Increase HPV Vaccine Uptake.
Selove R, Foster M, Mack R, Sanderson M, Hull PC
(2017) J Public Health Manag Pract 23: e1-e9
MeSH Terms: Adult, Continental Population Groups, Female, Health Knowledge, Attitudes, Practice, Health Personnel, Humans, Incidence, Male, Middle Aged, Papillomavirus Infections, Papillomavirus Vaccines, Patient Acceptance of Health Care, Qualitative Research, Tennessee, United States, Uterine Cervical Neoplasms, Vaccination
Show Abstract · Added February 21, 2017
BACKGROUND - Although the incidence of cervical cancer has been decreasing in the United States over the last decade, Hispanic and African American women have substantially higher rates than Caucasian women. The human papillomavirus (HPV) is a necessary, although insufficient, cause of cervical cancer. In the United States in 2013, only 37.6% of girls 13 to 17 years of age received the recommended 3 doses of a vaccine that is almost 100% efficacious for preventing infection with viruses that are responsible for 70% of cervical cancers. Implementation research has been underutilized in interventions for increasing vaccine uptake. The Consolidated Framework for Implementation Research (CFIR), an approach for designing effective implementation strategies, integrates 5 domains that may include barriers and facilitators of HPV vaccination. These include the innovative practice (Intervention), communities where youth and parents live (Outer Setting), agencies offering vaccination (Inner Setting), health care staff (Providers), and planned execution and evaluation of intervention delivery (Implementation Process).
METHODS - Secondary qualitative analysis of transcripts of interviews with 30 community health care providers was conducted using the CFIR to code potential barriers and facilitators of HPV vaccination implementation.
RESULTS - All CFIR domains except Implementation Process were well represented in providers' statements about challenges and supports for HPV vaccination.
CONCLUSION - A comprehensive implementation framework for promoting HPV vaccination may increase vaccination rates in ethnically diverse communities. This study suggests that the CFIR can be used to guide clinicians in planning implementation of new approaches to increasing HPV vaccine uptake in their settings. Further research is needed to determine whether identifying implementation barriers and facilitators in all 5 CFIR domains as part of developing an intervention contributes to improved HPV vaccination rates.

Parvez S, Abdel-Kader K, Pankratz VS, Song MK, Unruh M
(2016) Clin J Am Soc Nephrol 11: 812-20
MeSH Terms: Adult, Aged, Attitude of Health Personnel, Clinical Competence, Conservative Treatment, Female, Health Care Surveys, Health Knowledge, Attitudes, Practice, Humans, Kidney Failure, Chronic, Male, Middle Aged, Nephrology, Patient Participation, Practice Patterns, Physicians', Primary Health Care, United States, Young Adult
Show Abstract · Added November 29, 2018
BACKGROUND AND OBJECTIVES - Despite the potential benefits of conservative management, providers rarely discuss it as a viable treatment option for patients with advanced CKD. This survey was to describe the knowledge, attitudes, and practices of nephrologists and primary care providers regarding conservative management for patients with advanced CKD in the United States.
DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS - We developed a questionnaire on the basis of a literature review to include items assessing knowledge, attitudes, and self-reported practices of conservative management for patients with advanced CKD. Potential participants were identified using the American Medical Association Physician Masterfile. We then conducted a web-based survey between April and May of 2015.
RESULTS - In total, 431 (67.6% nephrologists and 32.4% primary care providers) providers completed the survey for a crude response rate of 2.7%. The respondents were generally white, men, and in their 30s and 40s. Most primary care provider (83.5%) and nephrology (78.2%) respondents reported that they were likely to discuss conservative management with their older patients with advanced CKD. Self-reported number of patients managed conservatively was >11 patients for 30.6% of nephrologists and 49.2% of primary care providers. Nephrologists were more likely to endorse difficulty determining whether a patient with CKD would benefit from conservative management (52.8% versus 36.2% of primary care providers), whereas primary care providers were more likely to endorse limited information on effectiveness (49.6% versus 24.5% of nephrologists) and difficulty determining eligibility for conservative management (42.5% versus 14.3% of nephrologists). There were also significant differences in knowledge between the groups, with primary care providers reporting more uncertainty about relative survival rates with conservative management compared with different patient groups.
CONCLUSIONS - Both nephrologists and primary care providers reported being comfortable with discussing conservative management with their patients. However, both provider groups identified lack of United States data on outcomes of conservative management and characteristics of patients who would benefit from conservative management as barriers to recommending conservative management in practice.

Show Abstract · Added April 17, 2019
As the role of genomics in health care grows, patients increasingly require adequate genetic literacy to fully engage in their care. This study investigated a model for delivering consumer-friendly genetic information to improve understanding of precision medicine using health literacy and learning style principles. My Cancer Genome (MCG), a freely available cancer decision support tool, was used as a testbed. MCG content on a melanoma tumor mutation, BRAF V600E, was translated to a 6th-grade reading level, incorporating multiple learning modalities. A total of 90 patients and caregivers were recruited from a melanoma clinic at an academic medical center and randomized to 3 groups. Group A (control) received an exact copy of text from MCG. Group B was given the same content with hyperlinks to videos explaining key genetic concepts, identified and labeled by the team as knowledge pearls. Group C received the translated content with the knowledge pearls embedded. Changes in knowledge were measured through pre and post questionnaires. Group C showed the greatest improvement in knowledge. The study results demonstrate that providing information based on health literacy and learning style principles can improve patients' understanding of genetic concepts, thus increasing their likelihood of taking an active role in any decision making concerning their health.

PheKB: a catalog and workflow for creating electronic phenotype algorithms for transportability.
Kirby JC, Speltz P, Rasmussen LV, Basford M, Gottesman O, Peissig PL, Pacheco JA, Tromp G, Pathak J, Carrell DS, Ellis SB, Lingren T, Thompson WK, Savova G, Haines J, Roden DM, Harris PA, Denny JC
(2016) J Am Med Inform Assoc 23: 1046-1052
MeSH Terms: Algorithms, Data Mining, Electronic Health Records, Genomics, Humans, International Classification of Diseases, Knowledge Bases, Natural Language Processing, Phenotype
Show Abstract · Added March 14, 2018
OBJECTIVE - Health care generated data have become an important source for clinical and genomic research. Often, investigators create and iteratively refine phenotype algorithms to achieve high positive predictive values (PPVs) or sensitivity, thereby identifying valid cases and controls. These algorithms achieve the greatest utility when validated and shared by multiple health care systems.Materials and Methods We report the current status and impact of the Phenotype KnowledgeBase (PheKB, http://phekb.org), an online environment supporting the workflow of building, sharing, and validating electronic phenotype algorithms. We analyze the most frequent components used in algorithms and their performance at authoring institutions and secondary implementation sites.
RESULTS - As of June 2015, PheKB contained 30 finalized phenotype algorithms and 62 algorithms in development spanning a range of traits and diseases. Phenotypes have had over 3500 unique views in a 6-month period and have been reused by other institutions. International Classification of Disease codes were the most frequently used component, followed by medications and natural language processing. Among algorithms with published performance data, the median PPV was nearly identical when evaluated at the authoring institutions (n = 44; case 96.0%, control 100%) compared to implementation sites (n = 40; case 97.5%, control 100%).
DISCUSSION - These results demonstrate that a broad range of algorithms to mine electronic health record data from different health systems can be developed with high PPV, and algorithms developed at one site are generally transportable to others.
CONCLUSION - By providing a central repository, PheKB enables improved development, transportability, and validity of algorithms for research-grade phenotypes using health care generated data.

Show Abstract · Added February 22, 2016
A clinic-based intervention study was conducted among high-risk human papillomavirus (HPV)-infected Latinas aged 18-64 years between April 2006 and May 2008 on the Texas-Mexico border. Women were randomly assigned to receive a printed material intervention (n=186) or usual care (n=187) and were followed at three months, six months, and 12 months through telephone surveys and review of medical records. The HPV knowledge of nearly all women had increased greatly, but only two-thirds of women reported they had received follow-up care within one year of diagnosis regardless of additional health education messaging. Our findings suggest that, regardless of type of health education messaging, Latinas living on the Texas-Mexico border are aware that follow-up care is recommended, but they may not receive this care. Individual, familial and medical care barriers to receipt of follow-up care may partially account for the higher rates of cervical cancer mortality in this region.

Starnes JR, McEvoy MD, Ehrenfeld JM, Sandberg WS, Wanderer JP
(2015) J Med Syst 39: 134
MeSH Terms: Accreditation, Anesthesiology, Clinical Competence, Efficiency, Organizational, Health Knowledge, Attitudes, Practice, Humans, Information Systems, Internship and Residency, Interpersonal Relations, Preoperative Period, Problem-Based Learning, Professionalism, Time Factors
Show Abstract · Added October 17, 2015
BACKGROUND - Accreditation Council for Graduate Medical Education (ACGME) core competencies of systems-based practice and practice-based learning and improvement are difficult to assess, as they are often not directly measurable or observable. Reviewing day-of-surgery cancellations could provide resident learning opportunities in these areas.
OBJECTIVE - An automated system to facilitate anesthesiology resident review of cancelled cases was implemented on the Preoperative Evaluation Clinic (PEC) rotation at the authors' institution. This study aims to evaluate its impact on resident education.
METHODS - Residents on the PEC rotation during the 6 months preceding (n = 22) and following (n = 13) implementation in 2014 were surveyed about their experience performing cancelled case reviews in order to ascertain the effect of the intervention on their training.
RESULTS - Significant changes were reported in the number of cases reviewed by each resident (p < 0.0001), perceived importance of review (p = 0.03), and ease of review (p = 0.03) after system implementation. There was also an increase in the proportion of cancelled cases reviewed from 17.3% (34 of 196) to 95.6% (194 of 203) (p < 0.0001). Non-significant trends were seen in perceived rotation effect on ACGME competencies, including systems-based practice. Several specific improvements to our clinical practice, including the creation of standardized guidelines, arose from these case reviews.
CONCLUSION - Implementation of automated systems can improve compliance with educational goals by clarifying priorities and simplifying workflow. This system increased the number of cases reviewed by residents and the perceived importance of this review as a part of their educational experience.

(2016) Behav Res Methods 48: 1178-96
MeSH Terms: Adult, Aged, Aged, 80 and over, Face, Female, Humans, Individuality, Internet, Knowledge, Male, Memory, Middle Aged, Psycholinguistics, Recognition (Psychology), Reproducibility of Results, Semantics, Visual Perception, Young Adult
Show Abstract · Added February 23, 2016
How much do people differ in their abilities to recognize objects, and what is the source of these differences? To address the first question, psychologists have created visual learning tests including the Cambridge Face Memory Test (Duchaine & Nakayama, 2006) and the Vanderbilt Expertise Test (VET; McGugin et al., 2012). The second question requires consideration of the influences of both innate potential and experience, but experience is difficult to measure. One solution is to measure the products of experience beyond perceptual knowledge-specifically, nonvisual semantic knowledge. For instance, the relation between semantic and perceptual knowledge can help clarify the nature of object recognition deficits in brain-damaged patients (Barton, Hanif, & Ashraf, Brain, 132, 3456-3466, 2009). We present a reliable measure of nonperceptual knowledge in a format applicable across categories. The Semantic Vanderbilt Expertise Test (SVET) measures knowledge of relevant category-specific nomenclature. We present SVETs for eight categories: cars, planes, Transformers, dinosaurs, shoes, birds, leaves, and mushrooms. The SVET demonstrated good reliability and domain-specific validity. We found partial support for the idea that the only source of domain-specific shared variance between the VET and SVET is experience with a category. We also demonstrated the utility of the SVET-Bird in experts. The SVET can facilitate the study of individual differences in visual recognition.

Show Abstract · Added April 11, 2017
Clinician attitudes toward multiplexed genomic testing may be vital to the success of translational programs. We surveyed clinicians at an academic medical center about their views on a large pharmacogenomics implementation, the PREDICT (Pharmacogenomic Resource for Enhanced Decisions in Care and Treatment) program. Participants were asked about test ordering, major factors influencing use of results, expectations of efficacy and responsibility for applying results to patient care. Virtually all respondents (99%) agreed that pharmacogenomics variants influence patients' response to drug therapy. The majority (92%) favored immediate, active notification when a clinically significant drug-genome interaction was present. However, clinicians were divided on which providers were responsible for acting on a result when a prescription change was indicated and whether patients should be directly notified of a significant result. We concluded genotype results were valued for tailoring prescriptions, but clinicians do not agree on how to appropriately assign clinical responsibility for actionable results from a multiplexed panel.The Pharmacogenomics Journal advance online publication, 11 August 2015; doi:10.1038/tpj.2015.57.
