Atrial Electrography for Postoperative Tachyarrhythmia Analysis in Patients.

The over 400,000 cardiac surgeries performed in the United States each year hold a risk for the postoperative complication of arrhythmias. Currently, bedside monitoring of surface electrocardiogram leads is used to interpret arrhythmias despite the evidence that atrial electrograms (AEGs) offer superior rhythm discrimination. This hesitancy to use the AEG may be due to a lack of training for practitioners in interpreting AEGs; therefore, our goal was to create an algorithm for the diagnosis of tachyarrhythmia using an AEG that can be utilized by any health care practitioner. Our algorithm classifies the most prevalent type of tachyarrhythmias following cardiac surgery. To allow rhythm identification, we categorized them based on their atrial to ventricular signal ratio, which is uniquely apparent on AEGs. Other considerations were given to rhythm regularity, consistency, P-wave axis, and rate. The algorithm includes the most common postoperative arrhythmias differentiated based on a unique branch-point approach, which walks through the steps in arrhythmia discrimination. Both rendered and collected AEGs are included as references for further understanding and interpretation of tachyarrhythmias. The utility of AEGs for rhythm discrimination post-cardiac surgery is established and recent technology can provide real-time and continuous monitoring; however, practitioner training may be inadequate. To bridge this divide, we created an algorithm so that existing atrial wires can be better used for an enhanced rhythm interpretation via AEGs.

Knowledge and Attitudes Toward Human Papillomavirus Vaccination Among Latina Mothers of South American and Caribbean Descent in the Eastern US.

Purpose: The purpose of this study was to examine knowledge, attitudes, barriers, and facilitators for human papillomavirus (HPV) vaccination among Latina mothers of HPV vaccine-eligible children in low-income urban areas, as well as useful strategies to improve HPV vaccination. Methods: The study included 132 Latina mothers of HPV vaccine-eligible children, interviewed in 14 focus groups. Using semi-structured discussions, mothers were asked about their knowledge about HPV infection and vaccine, views toward HPV vaccination, barriers for HPV vaccine initiation as well as completion, and opinions on strategies to improve HPV vaccination. Results: Only 55% of mothers reported having ever heard of the HPV vaccine, 27% of mothers indicated initiating the HPV vaccine, and 14% indicated completing the multi-dose series. Mothers generally lacked knowledge about HPV infection and vaccination, with varying degrees by Latino descent. Health care provider (HCP) recommendation was the strongest barrier/facilitator for HPV vaccination. Useful strategies to improve HPV vaccine initiation and completion that the mothers suggested included strong recommendation from HCPs and addressing side effects and safety concerns. Other useful strategies included community and school-based approaches and the use of text messaging and smartphone technology to educate mothers and send vaccine reminders. Conclusion: The findings provide insight for the development of interventions targeting low-income Latina mothers and the need to improve HCP communication on HPV vaccination.

A Clustered Randomized Trial of an Educational Intervention During Transplant Evaluation to Increase Knowledge of Living Donor Kidney Transplant.

INTRODUCTION: Maximizing education about living donor kidney transplant (LDKT) during the in-person evaluation at the transplant center may increase the numbers of kidney patients pursuing LDKT. Research Questions and Design: To test the effectiveness of a 1-time LDKT educational intervention, we performed a cluster-randomized trial among 499 patients who presented for evaluation of kidney transplant. We compared usual care education (n = 250) versus intensive LDKT education (n = 249), which was implemented only on the evaluation day and consisted of viewing a 25-minute video of information and stories about LDKT and discussion of LDKT possibilities with an educator. Our primary outcome was knowledge of LDKT, 1 week after the transplant evaluation. RESULTS: One week after evaluation, patients who received intensive education had higher knowledge than patients who received usual care (12.7 vs. 11.7; P = .0008), but there were no differences in postevaluation readiness for LDKT. Among patients who had not previously identified a potential living donor, receiving intensive education was associated with increased willingness to take steps toward LDKT. DISCUSSION: In conclusion, expansion of LDKT education within the evaluation day may be helpful, but interventions that are implemented at multiple times and for greater duration may be necessary to ensure larger and long-term behavioral changes in pursuit of LDKT.

Initiation of Human Papillomavirus Vaccination Among Predominantly Minority Female and Male Adolescents at Inner-City Community Health Centers.

OBJECTIVES: We examined the prevalence and correlates of human papillomavirus (HPV) vaccine initiation among adolescents in low-income, urban areas. METHODS: The study consisted of electronic health record data on HPV vaccination for 3180 adolescents (aged 10-20 years) at a multisite community health center in 2011. RESULTS: Only 27% initiated the HPV vaccine. The adjusted odds ratio (AOR) of HPV vaccination was lower among older adolescents (AOR = 0.552; 95% confidence interval [CI] = 0.424, 0.718) and those seen by nonpediatric health care providers (HCPs; AOR = 0.311; 95% CI = 0.222, 0.435), and higher among non-English speakers (AOR = 1.409; 95% CI = 1.134, 1.751) and those seen at 2 site locations (AOR = 1.890; 95% CI = 1.547, 2.311). Insurance status was significant only among female and Hispanic adolescents. Language was not a predictor among Hispanic adolescents. Across all analyses, the interaction of age and HCP specialty was associated with HPV vaccination. Dramatically lower HPV vaccination rates were found among older adolescents seen by nonpediatric HCPs (3%-5%) than among other adolescents (23%-45%). CONCLUSIONS: Improving HPV vaccination initiation in low-income urban areas is critical to reducing disparities in cervical and other HPV-related cancer, especially among Black, Hispanic, and low-income populations.

HPV Vaccination Completion and Compliance with Recommended Dosing Intervals Among Female and Male Adolescents in an Inner-City Community Health Center.

Human papillomavirus (HPV) vaccination continues to lag behind other adolescent vaccines, especially in areas with pervasive disparities in HPV-related cancers. The purpose of this study was to examine HPV vaccine completion and dosing intervals among low-income adolescents in urban areas. The study included electronic health record data on HPV vaccination for 872 adolescents who received at least one dose of the HPV vaccine. Only 28.4% completed the 3-dose series. For the whole sample, HPV vaccine completion was higher for non-English speakers and among adolescents seen at Newark-South and East Orange sites. Completion was higher among non-English speaking female and Hispanic adolescents, females seen in Newark-South and East Orange sites, and insured Black adolescents. Completion was also dramatically lower among non-English speaking Black adolescents seen at Newark-North, Irvington, and Orange sites (12.5%) compared to other Black adolescents (22.0-44.4%). The mean dosing intervals were 5.5 months (SD = 4.6) between dose 1 and 2 and 10 months (SD = 6.1) between dose 1 and 3. Longer durations between vaccine doses were found among uninsured adolescents and those seen at Newark-North, Irvington, and Orange sites. Non-English speakers had longer duration between dose 1 and 3. Further, durations between dose 1 and 3 were dramatically longer among insured adolescents seen at Newark-North, Irvington, and Orange locations for the whole sample (M = 11.70; SD = 7.12) and among Hispanic adolescents (M = 13.45; SD = 8.54). Understanding how the study predictors facilitate or impede HPV vaccination is critical to reducing disparities in cervical and other HPV-related cancer, especially among Black, Hispanic, and low-income populations.

Protocol of a cluster randomized trial of an educational intervention to increase knowledge of living donor kidney transplant among potential transplant candidates.

BACKGROUND: The best treatment option for end-stage renal disease is usually a transplant, preferably a live donor kidney transplant (LDKT). The most effective ways to educate kidney transplant candidates about the risks, benefits, and process of LDKT remain unknown. METHODS/DESIGN: We report the protocol of the Enhancing Living Donor Kidney Transplant Education (ELITE) Study, a cluster randomized trial of an educational intervention to be implemented during initial transplant evaluation at a large, suburban U.S. transplant center. Five hundred potential transplant candidates are cluster randomized (by date of visit) to receive either: (1) standard-of-care ("usual") transplant education, or (2) intensive education that is based upon the Explore Transplant series of educational materials. Intensive transplant education includes viewing an educational video about LDKT, receiving print education, and meeting with a transplant educator. The primary outcome consists of knowledge of the benefits, risks, and process of LDKT, assessed one week after the transplant evaluation. As a secondary outcome, knowledge and understanding of LDKT are assessed 3 months after the evaluation. Additional secondary outcomes, assessed one week and 3 months after the evaluation, include readiness, self-efficacy, and decisional balance regarding transplant and LDKT, with differences assessed by race. Although the unit of randomization is the date of the transplant evaluation visit, the unit of analysis will be the individual potential transplant candidate. DISCUSSION: The ELITE Study will help to determine how education in a transplant center can best be designed to help Black and non-Black patients learn about the option of LDKT. TRIAL REGISTRATION: Clinicaltrials.gov number NCT01261910.

Knowledge and acceptability of the HPV vaccine among ethnically diverse black women.

The purpose of the study was to examine HPV vaccine knowledge and acceptability among ethnically diverse Black women. Forty-four women were interviewed in 6 focus groups (2 African American, 2 English-speaking Caribbean, 1 Haitian, and 1 African). Thematic content analysis was used to generate common concepts and themes and to compare findings across groups. There was varied but limited knowledge and confusion across ethnic groups about the HPV infection and vaccine. African and Haitian women had the least knowledge. Overall, women were generally receptive toward the HPV vaccine for girls but unclear about the need to vaccinate boys. Concerns about the HPV vaccine were mainly related to side effects/safety and vaccinating children at a young age. Healthcare provider's recommendation of the vaccination was important for decision making. Educational interventions with Black women about HPV vaccination should recognize cultural beliefs that vary by ethnic group.

Improving the delivery of patient education about kidney transplant in a transplant center.

CONTEXT: Kidney transplant is usually the best treatment option for patients with end-stage renal disease; however, transplant rates remain low in the United States. More research is needed about patients' educational needs to ensure that patients are making informed decisions about their treatment options. OBJECTIVE: To examine patients' perceptions of the delivery and format of a kidney transplant education program in a clinical setting, specifically to (1) identify useful aspects of the transplant education process, (2) discuss aspects of the program delivery that need improvement, and (3) provide recommendations to enhance the education delivery and format surrounding kidney transplant. DESIGN: A descriptive study using focus group meetings with patients at different stages of the transplantation process (in evaluation, listed, and transplant recipients). Data were analyzed by using thematic content analysis. RESULTS: Use of printed materials and handouts, group education format, and patient advocate component as well as bringing a companion were all effective aspects of the education program. Concerns about the education program stemmed from its complexity, technicality, and length. Participants recommended that patients be sent a formal invitation letter, with a detailed agenda and a video on kidney transplant, and that patients be encouraged to bring a companion to the education program. Responses specific to the stage of the transplant process are presented. CONCLUSION: Concentrated attention to the delivery and content of the transplant education programs may significantly assist with patients' outcomes throughout the transplant process.

Cervical cancer screening among ethnically diverse black women: knowledge, attitudes, beliefs, and practices.

This is a descriptive study of cervical cancer screening knowledge, attitudes, beliefs, and practices among ethnically diverse black women. We conducted 6 focus groups with Haitian, African, English-speaking Caribbean, and African American women recruited from a federally qualified health center. Overall, there was limited knowledge and confusion across ethnic groups about cervical cancer and its risk factors, the Pap test, and the human papilloma virus (HPV) and its association with cervical cancer. At the same time, there were distinct differences between ethnic groups in knowledge, practices, and cultural beliefs about cervical cancer. African women knew the least among all the groups, while African American participants had the greatest knowledge of HPV. However, their knowledge was still limited. Patient-doctor relationship was the single most important facilitator for cervical cancer screening. Barriers to cervical cancer screening included cost, busy work schedule, fear of the unknown, lack of insurance or being unemployed, and fear of disclosing immigration status. Interventions with ethnically diverse black women would benefit from recognizing cultural barriers and misconceptions that vary by ethnic group. Culturally based strategies suggested by the focus groups include the use of existing social networks, the use of indigenous community-based health workers, and the inclusion of women of all ages in cervical cancer education because of the roles they have in extended families.

A pilot trial of spirituality counseling for weight loss maintenance in African American breast cancer survivors.

A continuing challenge in weight loss treatment is attaining maintenance of weight loss. The goal of this study was to develop a counseling method that would assist African American breast cancer survivors with weight loss maintenance. In this pilot study, 31 obese breast cancer survivors were recruited. Individualized, dietitian-led counseling by telephone and free Weight Watchers coupons were provided to all participants for 18 months. At the 6-month time point, women were randomized to receive spirituality counseling or not in addition to the standard program. The spirituality counseling was delivered via telephone using an 8-step framework. Subjects were asked to utilize daily meditation or prayer, daily readings, and the recording of thoughts in a journal. Mean weight loss from baseline to 6 months was a modest 2.0% of baseline weight. From 6 to 18 months, there was no further weight change in the spirituality arm and a gain of 0.7% in the dietitian-only arm. Despite little effect on weight loss, it did appear that spirituality counseling positively affected spiritual well-being (FACIT-Sp) scores and dietary quality. The spirituality counseling framework therefore may be further refined and useful for other health promotion studies with African American populations.

Knowledge and barriers related to prostate and colorectal cancer prevention in underserved black men.

OBJECTIVES: This qualitative study examined underserved black males' perspectives about prostate and colorectal cancer screening. METHODS: Black male residents of Newark, NJ, > or =18 years of age, were recruited to participate in focus groups. Two groups were conducted with a total of 24 participants. Transcripts were analyzed using an immersion/crystallization approach. RESULTS: Three major themes were identified, while men reflected on their experiences with prostate and colorectal cancer screening: (1) motivation for seeking screening; (2) fear associated with screenings: and (3) healthcare system barriers (e.g., patient-doctor relationships, insurance and mistrust of healthcare professionals). Participants also gave recommendations on how to increase preventive screening. DISCUSSION: Fear and past experiences with healthcare serve as motivators and demotivators of preventive screening behavior. Interventions that address motivation and fear are recommended to increase preventive screening among this population.

Normative health research experiences among African American elders.

OBJECTIVE: Data are meager regarding the prevalence of participation and the overall experience of African American elders in research across a variety of health-related studies. This study sought to increase our knowledge about older African Americans' participation in health research by capturing some of their normative experiences and attitudes. METHODS: A telephone-based survey was conducted on 1,290 urban African Americans greater than or equal to 60 years old. The assessment focused on issues of housing, neighborhoods, health, and experiences with health research. RESULTS: The overall prevalence of respondents who took part in a health research project was 14%. Significant predictors included income, attitudes about fairness, perceptions of protection from harm, understanding of research as a key to improving health care, and participation in survey research. DISCUSSION: Findings underscore the importance of addressing economic, educational, and trust barriers to research participation as well as the importance of conveying a sense of caring for the health of individuals and the community as a whole.

Factors associated with breast cancer clinical trials participation and enrollment at a large academic medical center.

PURPOSE: The practice patterns of medical oncologists at a large National Cancer Institute Comprehensive Cancer Center in Detroit, MI were evaluated to better understand factors associated with accrual to breast cancer clinical trials. PATIENTS AND METHODS: From 1996 to 1997, physicians completed surveys on 319 of 344 newly evaluated female breast cancer patients. The 19-item survey included clinical data, whether patients were offered clinical trial (CT) participation and enrollment, and when applicable, reasons why they were not. Multivariate analyses using logistic regression were performed to evaluate predictors of an offer and enrollment. RESULTS: The patients were 57% white, 32% black, and 11% other/unknown race. One hundred six (33%) were offered participation and 36 (34%) were enrolled. In multivariate analysis, CTs were less likely offered to older women (mean age, 52 years for those offered v 57 years for those not offered; P =.0005) and black women (21% of blacks offered v 42% of whites; P =.0009). Women with stage 1 disease, poor performance status, and those who were previously diagnosed were also less likely to be offered trials. None of these factors were significant predictors of enrollment. Women were not offered trials because of ineligibility (57%), lack of available trials (41%), and noncompliance (2%). Reasons for failed enrollment included patient refusal (88%) and failed eligibility (12%). CONCLUSION: It is important for cooperative groups to design studies that will accommodate a broader spectrum of patients. Further work is needed to assess ways to improve communication about breast cancer CT participation to all eligible women.

Willingness to participate in clinical treatment research among older African Americans and Whites.

PURPOSE: Using a health services utilization conceptual framework, the purpose of this analysis was to examine race differences in factors predictive of the behavioral intention of older persons to participate in a clinical treatment trial should they have a diagnosis of cancer. In addition, the analysis sought to determine if older African Americans were less likely than Whites to express willingness to participate, given knowledge of the Tuskegee syphilis study and greater fatalistic cancer beliefs. DESIGN AND METHODS: Data were drawn from a community-based telephone survey of 216 African Americans and 222 Whites, 50 years of age and older. RESULTS: Findings show that willingness to participate was significantly higher among males, persons of younger age, higher incomes, and with nonfatalistic cancer beliefs. Race differences were only apparent for the two significant interactions of race with age and high income. Neither knowledge of the Tuskegee study nor fatalistic cancer beliefs were more important for African Americans than for Whites. IMPLICATIONS: Study findings suggest that recruitment strategies need to be tailored to racial differences in factors affecting willingness to participate, particularly those related to age and income level.
