Access to prenatal exome sequencing for fetal malformations: A qualitative landscape analysis in the US

OBJECTIVE

There is increasing evidence supporting the clinical utility of next generation sequencing for identifying fetal genetic disorders. However, there are limited data on the demand for and accessibility of these tests, as well as payer coverage in the prenatal context. We sought to identify clinician perspectives on the utility of prenatal exome sequencing (ES) and on equitable access to genomic technologies for the care of pregnancies complicated by fetal structural anomalies.

METHOD

We conducted two focus group discussions and six interviews with a total of 13 clinicians (11 genetic counselors; 2 Maternal Fetal Medicine/Geneticists) from U.S. academic centers and community clinics.

RESULTS

Participants strongly supported ES for prenatal diagnostic testing in pregnancies with fetal structural anomalies. Participants emphasized the value of prenatal ES as an opportunity for a continuum of care before, during, and after a pregnancy, not solely as informing decisions about abortions. Cost and coverage of the test was the main access barrier, and research was the main pathway to access ES in academic centers.

CONCLUSION

Further integrating the perspectives of additional key stakeholders are important for understanding clinical utility, developing policies and practices to address access barriers, and assuring equitable provision of prenatal diagnostic testing.

The Need to Standardize the Reanalysis of Genomic Sequencing Results: Findings from Interviews with Underserved Families in Genomic Research

The reanalysis of genomic sequencing results has the potential to provide results that are of considerable medical and personal importance to recipients. Employing interviews with forty-seven predominantly medically underserved families and ethnographic observations we argue that there is pressing need to standardize the approach taken to reanalysis. Our findings highlight that study participants were unclear as to the likelihood of reanalysis happening, the process of initiating reanalysis, and whether they would receive revised results. Their reflections mirror the lack a specific focus upon reanalysis within consent and results sessions as observed in clinical settings. Mechanisms need to be put into place that standardize the approach to reanalysis in research and in clinical contexts. This would enable clinicians and genetic counsellors to communicate clearly with research participants with respect to potential for reanalysis of results and the process of reanalysis. We argue that that the role of reanalysis is too important to be referred to in an ad-hoc manner. Furthermore, the ad-hoc nature of the current process may increase health inequities given the likelihood that only those families who have the means to press for reanalysis are likely to receive it.

Clinical decision support and electronic interventions to improve care quality in chronic liver diseases and cirrhosis

Significant quality gaps exist in the management of chronic liver diseases and cirrhosis. Clinical decision support systems-information-driven tools based in and launched from the electronic health record-are attractive and potentially scalable prospective interventions that could help standardize clinical care in hepatology. Yet, clinical decision support systems have had a mixed record in clinical medicine due to issues with interoperability and compatibility with clinical workflows. In this review, we discuss the conceptual origins of clinical decision support systems, existing applications in liver diseases, issues and challenges with implementation, and emerging strategies to improve their integration in hepatology care.

Diagnostic yield of pediatric and prenatal exome sequencing in a diverse population

The diagnostic yield of exome sequencing (ES) has primarily been evaluated in individuals of European ancestry, with less focus on underrepresented minority (URM) and underserved (US) patients. We evaluated the diagnostic yield of ES in a cohort of predominantly US and URM pediatric and prenatal patients suspected to have a genetic disorder. Eligible pediatric patients had multiple congenital anomalies and/or neurocognitive disabilities and prenatal patients had one or more structural anomalies, disorders of fetal growth, or fetal effusions. URM and US patients were prioritized for enrollment and underwent ES at a single academic center. We identified definitive positive or probable positive results in 201/845 (23.8%) patients, with a significantly higher diagnostic rate in pediatric (26.7%) compared to prenatal patients (19.0%) (P = 0.01). For both pediatric and prenatal patients, the diagnostic yield and frequency of inconclusive findings did not differ significantly between URM and non-URM patients or between patients with US status and those without US status. Our results demonstrate a similar diagnostic yield of ES between prenatal and pediatric URM/US patients and non-URM/US patients for positive and inconclusive results. These data support the use of ES to identify clinically relevant variants in patients from diverse populations.

Pediatric Primary Care Perspectives of Mental Health Services Delivery during the COVID-19 Pandemic

Due to a national shortage of child and adolescent psychiatrists, pediatric primary care providers (PCPs) are often responsible for the screening, evaluation, and treatment of mental health disorders. COVID-19 pandemic stay-at-home orders decreased access to mental health care and increased behavioral and emotional difficulties in children and adolescents. Despite increased demand upon clinicians, little is known about mental health care delivery in the pediatric primary care setting during the pandemic. This focus group study explored the experiences of pediatric PCPs and clinical staff delivering mental health care during the pandemic. Transcripts from nine focus groups with San Francisco Bay Area primary care practices between April and August 2020 were analyzed using a thematic analysis approach. Providers expressed challenges at the patient-, provider-, and system-levels. Many providers reported increased patient mental health symptomatology during the pandemic, which was often intertwined with patients’ social determinants of health. Clinicians discussed the burden of the pandemic their own wellness, and how the rapid shift to telehealth primary care and mental health services seemed to hinder the availability and effectiveness of many resources. The findings from this study can inform the creation of new supports for PCPs and clinical staff providing mental health care.

Differences in Hospitals' Workplace Violence Incident Reporting Practices: A Mixed Methods Study

Workplace violence (WV) is a significant and growing problem for health care workers. Increased recognition of the need for improved protections has led to policy initiatives at the state and federal levels, including national Joint Commission requirements that went into effect January 2022. California's WV prevention legislation was phased in during 2017-2018 and requires hospitals to use a new incident reporting system, the Workplace Violent Incident Reporting System (WVIRS) for Hospitals. We analyzed WVIRS data collected during the first three years of its implementation, July 1, 2017 - June 30, 2020. In addition, we collected qualitative data from six California hospitals/hospital systems during 2019-2020 to better understand reporting practices. Over the three-year period, the 413 hospitals using the WVIRS reported between zero and six incidents per staffed bed. Sixteen hospitals (3.9%) reported two or more incidents per staffed bed while the rest reported fewer than two incidents. Qualitative analysis identified that reporting procedures vary considerably among hospitals. Several organizations rely on workers to complete incident reports electronically while others assign managers or security personnel to data collection. Some hospitals appear to report only those incidents involving physical harm to the worker. Regulatory guidance for reporting practices and hospitals' commitment to thorough data collection may improve consistency. As hospitals throughout the U.S. consider practice changes to comply with new WV standards, those engaged in implementation efforts should look closely at reporting practices. Greater consistency in reporting across facilities can help to build evidence for best practices and lead to safety improvements.

Integration of stakeholder engagement from development to dissemination in genomic medicine research: Approaches and outcomes from the CSER Consortium

PURPOSE

There is a critical need for genomic medicine research that reflects and benefits socioeconomically and ancestrally diverse populations. However, disparities in research populations persist, highlighting that traditional study designs and materials may be insufficient or inaccessible to all groups. New approaches can be gained through collaborations with patient/community stakeholders. Although some benefits of stakeholder engagement are recognized, routine incorporation into the design and implementation of genomics research has yet to be realized.

METHODS

The National Institutes of Health-funded Clinical Sequencing Evidence-Generating Research (CSER) consortium required stakeholder engagement as a dedicated project component. Each CSER project planned and carried out stakeholder engagement activities with differing goals and expected outcomes. Examples were curated from each project to highlight engagement strategies and outcomes throughout the research lifecycle from development through dissemination.

RESULTS

Projects tailored strategies to individual study needs, logistical constraints, and other challenges. Lessons learned include starting early with engagement efforts across project stakeholder groups and planned flexibility to enable adaptations throughout the project lifecycle.

CONCLUSION

Each CSER project used more than 1 approach to engage with relevant stakeholders, resulting in numerous adaptations and tremendous value added throughout the full research lifecycle. Incorporation of community stakeholder insight improves the outcomes and relevance of genomic medicine research.

Readiness to implement on-site molecular testing for tuberculosis in community health centers in Uganda

Background

Newer molecular testing platforms are now available for deployment at lower-level community health centers. There are limited data on facility- and health worker-level factors that would promote successful adoption of such platforms for rapid tuberculosis (TB) testing and treatment initiation. Our study aimed to assess readiness to implement onsite molecular testing at community health centers in Uganda, a high TB burden country in sub-Saharan Africa.

Methods

To understand implementation readiness, we conducted a qualitative assessment guided by the Consolidated Framework for Implementation Research (CFIR) at 6 community health centers in central and eastern Uganda between February and April 2018. We conducted 23 in-depth, semi-structured interviews with health workers involved in TB care at each health center to assess TB-related work practices and readiness to adopt onsite molecular testing using the GeneXpert Edge platform. Interviews were transcribed verbatim and coded for thematic analysis.

Results

Participants (N=23) included 6 nurses/nursing assistants, 6 clinicians, 6 laboratory directors/technicians, 1 medical officer, 2 health center directors, and 2 other health workers involved in TB care. Health workers described general enthusiasm that on-site molecular testing could lead to greater efficiencies in TB diagnosis and treatment, including faster turn- around time for TB test results, lack of need for trained laboratory technicians to interpret results, and reduced need to transport sputum specimens to higher level facilities. However, health workers also expressed concerns about implementation feasibility. These included uncertainty about TB infection risk, safety risks from disposal of hazardous waste, a lack of local capacity to provide timely troubleshooting and maintenance services, and concerns about the security of GeneXpert devices and accessories. Health workers also expressed the need for backup batteries to support testing or charging when wall power is unstable.

Conclusion

Our study generated a nuanced understanding of modifiable contextual barriers and led to direct revisions of implementation strategies for onsite molecular testing. The findings highlight that novel diagnostics should be implemented along with health system co-interventions that address contextual barriers to their effective uptake. Pre-implementation assessment of stakeholder perspectives, collaborative work processes, and institutional contexts is essential when introducing innovative technology in complex health care settings.

Multicomponent Strategy with Decentralized Molecular Testing for Tuberculosis

BACKGROUND

Effective strategies are needed to facilitate the prompt diagnosis and treatment of tuberculosis in countries with a high burden of the disease.

METHODS

We conducted a cluster-randomized trial in which Ugandan community health centers were assigned to a multicomponent diagnostic strategy (on-site molecular testing for tuberculosis, guided restructuring of clinic workflows, and monthly feedback of quality metrics) or routine care (on-site sputum-smear microscopy and referral-based molecular testing). The primary outcome was the number of adults treated for confirmed tuberculosis within 14 days after presenting to the health center for evaluation during the 16-month intervention period. Secondary outcomes included completion of tuberculosis testing, same-day diagnosis, and same-day treatment. Outcomes were also assessed on the basis of proportions.

RESULTS

A total of 20 health centers underwent randomization, with 10 assigned to each group. Of 10,644 eligible adults (median age, 40 years) whose data were evaluated, 60.1% were women and 43.8% had human immunodeficiency virus infection. The intervention strategy led to a greater number of patients being treated for confirmed tuberculosis within 14 days after presentation (342 patients across 10 intervention health centers vs. 220 across 10 control health centers; adjusted rate ratio, 1.56; 95% confidence interval [CI], 1.21 to 2.01). More patients at intervention centers than at control centers completed tuberculosis testing (adjusted rate ratio, 1.85; 95% CI, 1.21 to 2.82), received a same-day diagnosis (adjusted rate ratio, 1.89; 95% CI, 1.39 to 2.56), and received same-day treatment for confirmed tuberculosis (adjusted rate ratio, 2.38; 95% CI, 1.57 to 3.61). Among 706 patients with confirmed tuberculosis, a higher proportion in the intervention group than in the control group were treated on the same day (adjusted rate ratio, 2.29; 95% CI, 1.23 to 4.25) or within 14 days after presentation (adjusted rate ratio, 1.22; 95% CI, 1.06 to 1.40).

CONCLUSIONS

A multicomponent diagnostic strategy that included on-site molecular testing plus implementation supports to address barriers to delivery of high-quality tuberculosis evaluation services led to greater numbers of patients being tested, receiving a diagnosis, and being treated for confirmed tuberculosis.

Frequency of violence towards healthcare workers in the United States' inpatient psychiatric hospitals: A systematic review of literature

The purpose of this systematic review is to determine the frequency of violent or aggressive behaviour towards healthcare workers in inpatient psychiatric settings in the United States. To achieve this aim, five databases were searched to find English-language quantitative studies reporting prevalence or incidence data of violence or aggression directed towards staff members in inpatient psychiatric settings. No limitations were set based on publication date, and intervention studies were included only if baseline data were provided. Of 335 total studies found, 38 full-text articles were suitable for full-text analysis based on inclusion and exclusion criteria, and 14 were included in the final review. Years of data collection ranged from 1986 to 2018, and a range of psychiatric facilities were represented, from small, private hospital units to large forensic institutions. Researchers utilized surveys, real-time incident reporting tools, and government databases, or a combination of strategies, to collect data related to workers' experiences on the job. Included research indicates that workplace violence in the U.S. inpatient psychiatric setting is a widespread problem, with 25-85% of survey respondents reporting an incident of physical aggression within the year prior to survey, and statewide workers' compensation findings indicating 2-7 claims due to assault per 100 000 employee hours. There are substantial differences between findings based on measurement strategy, making it difficult to arrive at a single estimate of prevalence nationally. As management of this persistent problem receives continued attention from stakeholders, it becomes increasingly important to define and measure the problem with the most appropriate tools.

The University of California San Francisco (UCSF) Training Program in Implementation Science: Program Experiences and Outcomes

Purpose: We evaluated outcomes of trainees who have completed the Certificate program in Implementation Science at the University of California San Francisco.

Methods: All students who completed the in-person Certificate Program between 2008 and 2015 (n = 71), or the online Certificate Program between 2016 and 2017 (n = 13), were eligible for our study. We assessed the potential impact of the Certificate Program on the professional development of trainees, through participant surveys on their self-reported level of comfort with pre-defined competencies, and on academic productivity.

Results: Of eligible trainees, 54 in-person (77%) and 13 online (100%) Certificate Program participants completed surveys. In-person trainees reported a total of 147 implementation science-related publications in peer-reviewed journals (median 3 publications/trainee, IQR 1–15). Thirty-four trainees (63%) reported being a Principal Investigator (PI) of 64 funded implementation science-related grants (median 2 grants/trainee, IQR 1–4). Fifteen percent (15%, n = 8) of participants reported receiving an NIH grant on which they were the PI, including R01 or P01 level funding (n = 4, 7%) and K awards (n = 3, 6%). Both in-person and online trainees reported median high to moderate confidence for all 12 competencies assessed. Confidence waned in skills aligning with later stages of implementation research for all trainees.

Conclusion: The moderate to high confidence in all competencies assessed and reported high level of academic productivity support the benefits of intensive, graduate-level training focused on applied methods to support career development of implementation scientists.

Patterns of usage and preferences of users for tuberculosis-related text messages and voice calls in Uganda

BACKGROUND

Little information exists about mobile phone usage or preferences for tuberculosis (TB) related health communications in Uganda.

METHODS

We surveyed household contacts of TB patients in urban Kampala, Uganda, and clinic patients in rural central Uganda. Questions addressed mobile phone access, usage, and preferences for TB-related communications. We collected qualitative data about messaging preferences.

RESULTS

We enrolled 145 contacts and 203 clinic attendees. Most contacts (58%) and clinic attendees (75%) owned a mobile phone, while 42% of contacts and 10% of clinic attendees shared one; 94% of contacts and clinic attendees knew how to receive a short messaging service (SMS) message, but only 59% of contacts aged 45 years (vs. 96% of contacts aged <45 years, P = 0.0001) did so. All contacts and 99% of clinic attendees were willing and capable of receiving personal-health communications by SMS. Among contacts, 55% preferred detailed messages disclosing test results, while 45% preferred simple messages requesting a clinic visit to disclose results.

CONCLUSIONS

Most urban household TB contacts and rural clinic attendees reported having access to a mobile phone and willingness to receive TB-related personal-health communications by voice call or SMS. However, frequent phone sharing and variable messaging abilities and preferences suggest a need to tailor the design and monitoring of mHealth interventions to target recipients.

Redesigning primary care in the safety net: A qualitative analysis of team-based care implementation

BACKGROUND

Team-based care is an innovative approach to primary care in which groups of health care professionals work collaboratively to manage care for groups of patients. Safety-net organizations face specific barriers to implementing health care innovations. More research is needed that documents the dynamics that inform implementation and sustainment of innovative practices in the safety net.

METHODS

We conducted qualitative fieldwork, including purposeful observation and semi-structured and informal interviews, to explore the implementation of care teams in safety-net clinics in California. Field notes and transcripts were analyzed using an inductive approach to identify overarching themes across sites.

RESULTS

Salient themes across clinics suggest that 1) well-designed physical layouts that promote sustained patterns of structured and spontaneous communication and collaboration are critical to creating high-functioning teams; 2) implementation of team-based care relies on a relaxing of the traditional clinic hierarchy into an agile organizational structure that empowers all clinic staff-most notably medical assistants-by facilitating an ethos of collaborative decision-making, interdependence, and shared responsibility; and 3) resource constraints related to recruitment and retention of qualified staff are key barriers to implementation.

CONCLUSIONS

Team-based care has the potential to improve patient outcomes, strengthen relationships and well-being among clinic staff, and expand staff roles to facilitate collective accomplishment of work goals. To successfully launch and sustain care teams in safety-net clinics, greater commitments to creating well-designed spaces and a re-envisioning of the training and compensation for medical assistants that reflects the valuable role these individuals can play appear to be necessary.

Safety-net institutions in the US grapple with new cholesterol treatment guidelines: a qualitative analysis from the PHoENIX Network

Background

Clinical performance measures, such as for cholesterol control targets, have played an integral role in assessing the value of care and translating evidence into clinical practice. New guidelines often require development of corresponding performance metrics and systems changes that can be especially challenging in safety-net health care institutions. Understanding how public health care institutions respond to changing practice guidelines may be critical to informing how we adopt evolving evidence in clinical settings that care for the most vulnerable populations.

Methods

We conducted six focus groups with representatives of California’s 21 public hospital systems to examine their reactions to the recent 2013 cholesterol treatment guideline.

Results

Participants reported a sense of confusion and lack of direction in implementing the new guideline. They cited organizational and data infrastructural inadequacies that made implementation of the new guidelines impractical in their clinical settings.

Conclusion

Adopting new performance measures to align with evolving cholesterol guidelines is a complex process that may work at odds with existing quality improvement priorities. Current efforts to translate evidence into practice may rely too much on performance measures and not enough on building capacity or support for innovative efforts to meet the goals of guidelines.

Efficiency, Efficacy, and Power in the Implementation of a Medication Adherence Aid

Nonadherence to medication regimens is common, with approximately 50% of patients not taking their medications as prescribed. The Universal Medication Schedule (UMS) is a set of standardized, evidence-based, and patient-centered instructions for pill-form medications that has demonstrated improvements in adherence by promoting patient comprehension. An urban, publicly funded, integrated health care system attempted to adopt UMS labeling but had limited success at its largest pilot site, which was a safety-net health care system's outpatient pharmacy. To assess barriers to implementation, we engaged pharmacists at this site in group interviews. We thematically analyzed transcripts by integrating sociological work on standardization with grounded theory methodologies. In addition to lacking technological infrastructure, tensions among efficiency, efficacy, and effectiveness, and tension between individual/biomedical versus population health perspectives emerged as barriers to implementation. Additionally, we discovered that hierarchies of professional power impeded uptake. For successful implementation of evidence-based practices for vulnerable populations in resource-poor settings, efforts must anticipate and reconcile the tensions among conflicting demands, professional hierarchies, and divergent orientations to patient care. [HLRP: Health Literacy Research and Practice. 2018;2(3):e128-e131.].

Evaluation Activities and Influences at the Intersection of Medical and Social Services

Despite a growing national interest in health care-based strategies focused on patients' social determinants of health (SDH), little has been compiled about the impacts of SDH interventions undertaken in clinical settings. To understand better what is known in this area and incentives and barriers to related research, we conducted 30 semi-structured interviews with leaders and researchers in for-and non-profit organizations developing interventions to bridge health and social service delivery. Key informants described evaluation activities primarily concentrated on program design and implementation, and less commonly on impact evaluations and dissemination research. A diversity of outcome variables being used in intervention research limits the ability to draw conclusions about comparative effectiveness. Major barriers to advancing effective research on these topics relate to confusion around ownership of the SDH space within the health care sector.

Performance Measurement and Target-Setting in California's Safety Net Health Systems

Health policies encourage implementing quality measurement with performance targets. The 2010-2015 California Medicaid waiver mandated quality measurement and reporting. In 2013, California safety net hospitals participating in the waiver set a voluntary performance target (the 90th percentile for Medicare preferred provider organization plans) for mammography screening and cholesterol control in diabetes. They did not reach the target, and the difference-in-differences analysis suggested that there was no difference for mammography ( P = .39) and low-density lipoprotein control ( P = .11) performance compared to measures for which no statewide quality improvement initiative existed. California's Medicaid waiver was associated with improved performance on a number of metrics, but this performance was not attributable to target setting on specific health conditions. Performance may have improved because of secular trends or systems improvements related to waiver funding. Relying on condition-specific targets to measure performance may underestimate improvements and disadvantage certain health systems. Achieving ambitious targets likely requires sustained fiscal, management, and workforce investments.

Identifying barriers to and facilitators of tuberculosis contact investigation in Kampala, Uganda: a behavioral approach

BACKGROUND

The World Health Organization recommends routine household tuberculosis contact investigation in high-burden countries but adoption has been limited. We sought to identify barriers to and facilitators of TB contact investigation during its introduction in Kampala, Uganda.

METHODS

We collected cross-sectional qualitative data through focus group discussions and interviews with stakeholders, addressing three core activities of contact investigation: arranging household screening visits through index TB patients, visiting households to screen contacts and refer them to clinics, and evaluating at-risk contacts coming to clinics. We analyzed the data using a validated theory of behavior change, the Capability, Opportunity, and Motivation determine Behavior (COM-B) model, and sought to identify targeted interventions using the related Behavior Change Wheel implementation framework.

RESULTS

We led seven focus-group discussions with 61 health-care workers, two with 21 lay health workers (LHWs), and one with four household contacts of newly diagnosed TB patients. We, in addition, performed 32 interviews with household contacts from 14 households of newly diagnosed TB patients. Commonly noted barriers included stigma, limited knowledge about TB among contacts, insufficient time and space in clinics for counselling, mistrust of health-center staff among index patients and contacts, and high travel costs for LHWs and contacts. The most important facilitators identified were the personalized and enabling services provided by LHWs. We identified education, persuasion, enablement, modeling of health-positive behaviors, incentivization, and restructuring of the service environment as relevant intervention functions with potential to alleviate barriers to and enhance facilitators of TB contact investigation.

CONCLUSIONS

The use of a behavioral theory and a validated implementation framework provided a comprehensive approach for systematically identifying barriers to and facilitators of TB contact investigation. The behavioral determinants identified here may be useful in tailoring interventions to improve implementation of contact investigation in Kampala and other similar urban settings.

States' Influences on Medicaid Investments to Address Patients' Social Needs

INTRODUCTION

Relationships between socioeconomic adversity and poor health have been well documented. Given these associations, Medicaid MCOs (MMCOs) have shown increasing interest in addressing social determinants of health (SDH) to improve health and decrease healthcare costs. The authors sought to better understand how contractual relationships with State Medicaid Agencies influence MMCO investments in addressing members' SDH.

METHODS

In 52 semi-structured key informant interviews, MMCO executives representing 17 geographically diverse MMCOs ranging in size, commercial status, and state participation in Medicaid expansion were asked to describe existing state and other influences on MMCO SDH-related activities. The authors followed an established iterative coding, thematic development, and interpretation process to analyze all interview transcripts. All data were collected and analyzed between November 2014 and November 2015.

RESULTS

Informants highlighted both general and state-specific regulations that limit MMCOs from incorporating SDH-oriented solutions into care delivery, including regulations governing claimable expenses, rate determination, and enrollment eligibility. MMCO leaders also made recommendations to State Medicaid Agencies to help overcome perceived barriers.

CONCLUSIONS

MMCO experiences should inform new strategies to sustainably implement SDH innovations. An initial promise of managed care was that an MMCO that improves member health through cost-efficient innovations would benefit financially. The views expressed in these interviews challenge this framework's suitability for promoting SDH innovations, as many SDH-promoting services may instead translate into financial losses for MMCOs, even as they produce positive impacts on members' health.

Qualitative analysis of programmatic initiatives to text patients with mobile devices in resource-limited health systems

Background

Text messaging is an affordable, ubiquitous, and expanding mobile communication technology. However, safety net health systems in the United States that provide more care to uninsured and low-income patients may face additional financial and infrastructural challenges in utilizing this technology. Formative evaluations of texting implementation experiences are limited. We interviewed safety net health systems piloting texting initiatives to study facilitators and barriers to real-world implementation.

Methods

We conducted telephone interviews with various stakeholders who volunteered from each of the eight California-based safety net systems that received external funding to pilot a texting-based program of their choosing to serve a primary care need. We developed a semi-structured interview guide based partly on the Consolidated Framework for Implementation Research (CFIR), which encompasses several domains: the intervention, individuals involved, contextual factors, and implementation process. We inductively and deductively (using CFIR) coded transcripts, and categorized themes into facilitators and barriers.

Results

We performed eight interviews (one interview per pilot site). Five sites had no prior texting experience. Sites applied texting for programs related to medication adherence and monitoring, appointment reminders, care coordination, and health education and promotion. No site texted patient-identifying health information, and most sites manually obtained informed consent from each participating patient. Facilitators of implementation included perceived enthusiasm from patients, staff and management belief that texting is patient-centered, and the early identification of potential barriers through peer collaboration among grantees. Navigating government regulations that protect patient privacy and guide the handling of protected health information emerged as a crucial barrier. A related technical challenge in five sites was the labor-intensive tracking and documenting of texting communications due to an inability to integrate texting platforms with electronic health records.

Conclusions

Despite enthusiasm for the texting programs from the involved individuals and organizations, inadequate data management capabilities and unclear privacy and security regulations for mobile health technology slowed the initial implementation and limited the clinical use of texting in the safety net and scope of pilots. Future implementation work and research should investigate how different texting platform and intervention designs affect efficacy, as well as explore issues that may affect sustainability and the scalability.

Health worker perspectives on barriers to delivery of routine tuberculosis diagnostic evaluation services in Uganda: a qualitative study to guide clinic-based interventions

BACKGROUND

Studies of the quality of tuberculosis (TB) diagnostic evaluation of patients in high burden countries have generally shown poor adherence to international or national guidelines. Health worker perspectives on barriers to improving TB diagnostic evaluation are critical for developing clinic-level interventions to improve guideline implementation.

METHODS

We conducted structured, in-depth interviews with staff at six district-level health centers in Uganda to elicit their perceptions regarding barriers to TB evaluation. Interviews were transcribed, coded with a standardized framework, and analyzed to identify emergent themes. We used thematic analysis to develop a logic model depicting health system and contextual barriers to recommended TB evaluation practices. To identify possible clinic-level interventions to improve TB evaluation, we categorized findings into predisposing, enabling, and reinforcing factors as described by the PRECEDE model, focusing on potentially modifiable behaviors at the clinic-level.

RESULTS

We interviewed 22 health center staff between February 2010 and November 2011. Participants identified key health system barriers hindering TB evaluation, including: stock-outs of drugs/supplies, inadequate space and infrastructure, lack of training, high workload, low staff motivation, and poor coordination of health center services. Contextual barrier challenges to TB evaluation were also reported, including the time and costs borne by patients to seek and complete TB evaluation, poor health literacy, and stigma against patients with TB. These contextual barriers interacted with health system barriers to contribute to sub-standard TB evaluation. Examples of intervention strategies that could address these barriers and are related to PRECEDE model components include: assigned mentors/peer coaching for new staff (targets predisposing factor of low motivation and need for support to conduct job duties); facilitated workshops to implement same day microscopy (targets enabling factor of patient barriers to completing TB evaluation), and recognition/incentives for good TB screening practices (targets low motivation and self-efficacy).

CONCLUSIONS

Our findings suggest that health system and contextual barriers work together to impede TB diagnosis at health centers and, if not addressed, could hinder TB case detection efforts. Qualitative research that improves understanding of the barriers facing TB providers is critical to developing targeted interventions to improve TB care.

Using Rapid Ethnography to Support the Design and Implementation of Health Information Technologies

Ethnography is the defining practice - and art - of anthropology. Among health information technology (IT) developers, however, ethnography remains a little used and undervalued mode of inquiry and representation. In this chapter we demonstrate that ethnography can make important contributions to the design and implementation of more user-oriented health IT devices and systems. In particular, we propose 'rapid ethnography' as a pragmatic strategy that draws on classic ethnographic methods, but emphasizes shorter periods of fieldwork and quick turnaround of findings to inform (re)design, programming and implementation efforts. Rapid ethnography is theoretically and empirically situated in science and technology studies' explorations of a) the entanglement of social and technical dimensions of technology use; b) how getting tools to 'work' requires aligning interests across a wide range of human and non-human actors; and c) the ways in which humans and technology transform each other as they interact. We provide two detailed case studies to illustrate the evolution and uses of rapid ethnography at a U.S. academic medical center. By providing deeper insights into the experiences of users, and the contexts and communities in which new tools are introduced, rapid ethnography can serve as a valuable component of Techno-Anthropology and health IT innovation.

A framework for training health professionals in implementation and dissemination science

The authors describe a conceptual framework for implementation and dissemination science (IDS) and propose competencies for IDS training. Their framework is designed to facilitate the application of theories and methods from the distinct domains of clinical disciplines (e.g., medicine, public health), population sciences (e.g., biostatistics, epidemiology), and translational disciplines (e.g., social and behavioral sciences, business administration education). They explore three principles that guided the development of their conceptual framework: Behavior change among organizations and/or individuals (providers, patients) is inherent in the translation process; engagement of stakeholder organizations, health care delivery systems, and individuals is imperative to achieve effective translation and sustained improvements; and IDS research is iterative, benefiting from cycles and collaborative, bidirectional relationships. The authors propose seven domains for IDS training-team science, context identification, literature identification and assessment, community engagement, intervention design and research implementation, evaluation of effect of translational activity, behavioral change communication strategies-and define 12 IDS training competencies within these domains. As a model, they describe specific courses introduced at the University of California, San Francisco, which they designed to develop these competencies. The authors encourage other training programs and institutions to use or adapt the design principles, conceptual framework, and proposed competencies to evaluate their current IDS training needs and to support new program development.

Abstract P4-11-13: A Multi-Institutional Assessment of the Feasibility, Implementation, and Early Clinical Results with Noninvasive Image-Guided Breast Brachytherapy for Tumor Bed Boost

Background: Noninvasive image-guided breast brachytherapy (NIIGBB) is an FDA-approved, commercially available (AccuBoost®, Billerica, MA) mammography-based, breast brachytherapy system whereby the treatment applicators are centered on the planning target volume (PTV) to direct 192Ir emissions along orthogonal axes. This study evaluates the feasibility, implementation, and early results of NIIGBB for breast tumor bed boost in combination with external beam whole breast radiation therapy (WBRT), as part of post-lumpectomy radiation.

Material and Methods: A privacy-encrypted online data registry was created to collect clinical and technical information from 8 independent academic and community-based institutions. Data were collected from consecutive 110 individual women with early stage breast cancer after breast conserving surgery, who received adjuvant WBRT (mean dose 48.3 ± 2.5 Gy) and tumor bed boost with NIIGBB between July, 2007 and March, 2010. Of the patients, 74% had invasive cancer, with 80% ER+ and 34% HER2+. NIIGBB was delivered before, during, or after WBRT in 57%, 39%, or 4% of the patients. Patient age and lumpectomy cavity size ranged from 32-88 yrs and 0.1-5.3 cm, respectively. Boost dose was delivered in 1.9 ± 0.3 Gy/fx for a total of 12.9 ± 3.4Gy. Toxicity and cosmesis were evaluated after radiation therapy and graded according to the Common Toxicity Criteria (v3.0) and the Harvard scale. Median follow up was 6 months (1-17 months).

Results: Grade 1-2 skin toxicity was observed in 18%, 7%, and 0% during the acute (1-3wks), intermediate (4-26 wks), and late-intermediate (&gt;26wks) periods. There were no Grade 3 or higher skin toxicity events. At 6 months, for the entire cohort, cosmetic grading was excellent, good, fair/poor in 52%, 48%, and 0%. The breast compression achieved for each treatment session was remarkably consistent with a mean mammographic plate separation of 6.4 ± 0.3 cm. Breast compression was scored as “uncomfortable” when NIIGBB was delivered before or during WBRT. The mean total duration of set-up and treatment per fraction was 16.7 ± 2.1 min. For each patient, the fraction-to-fraction variability in estimated PTV was low as 69% of treatments were completed with the same applicator size.

Discussion: These data indicate that NIIGBB is feasible and can be consistently implemented in a broad array of practice settings. Preliminary evaluation suggests that NIIGBB is associated with acceptably mild normal tissue toxicity and favorable early cosmetic results. The application of

NIIGBB before completion of WBRT may be associated with better patient tolerance at the expense of slightly less favorable short-term cosmetic outcome.

Generativity in midlife and young adults: links to agency, communion and subjective well-being

Three questions stimulated by Erik Erikson's theory of generativity were addressed: 1) Is generativity associated with greater subjective well-being? 2) Are agency and communion additive or interactive predictors of generativity? 3) Does generativity play a distinct role during the midlife period? Among ninety-eight midlife adults, generativity was positively related to positive affectivity, satisfaction with life, and work satisfaction. Generativity was independently predicted by agentic (masculine) and communal (feminine) traits. Among fifty-eight young adults, generativity predicted positive affect at home. Generativity was independently predicted by agentic (power) and communal (love) interpersonal orientations. Using event-contingent recording of agentic and communal behavior at work, agency was a stronger predictor of generativity for young adult men, and communion was a stronger predictor for young adult women. The studies demonstrate that generativity has similar relations to agency and communion in young and midlife adults; however, generativity may be a stronger predictor of subjective well-being in midlife adults.

Treatment outcomes for female octogenarians with breast cancer

Scant information is available comparing the treatment outcomes of minor surgery (lumpectomy) versus extensive treatment (radical and simple mastectomy or lumpectomy and radiation) in octogenarians with breast cancer. Medical records of women (ages 80-89) who received treatment for breast cancer from 1984 through 1994 were reviewed. All patients were stage T1 or T2, and none had palpable lymph nodes. The recurrence rate, disease-free interval, and death rate for both groups were compared. Of the 41 patients representing 43 minor surgeries, 12 per cent (5 of 41) of patients developed recurrence, all of which were related to the primary breast tumor. The mean disease-free interval was 28.6 +/- 24.7 months (range, 6-65). Forty-six per cent (18 of 39) of patients died, 10 per cent (4 of 39) from recurrence and metastatic disease from breast cancer and 36 per cent (14 of 39) from other causes. Of those who underwent extensive treatment, 14.6 per cent (7 of 48) of patients experienced recurrence, all related to the primary breast tumor. The mean disease-free interval was 24.0 +/- 21.9 months (range, 2-71). Forty-eight per cent (23 of 48) of patients died, 10 per cent (5 of 48) from recurrence and metastatic disease from breast cancer and 37 per cent (18 of 48) from other causes. None of the differences between the minor surgery versus extensive treatment groups were statistically significant. The recurrence rate, disease-free interval, and death rate from recurrent disease are similar for patients undergoing minor surgery compared with those undergoing extensive treatment.

Oral immunization with urease and Escherichia coli heat-labile enterotoxin is safe and immunogenic in Helicobacter pylori-infected adults

BACKGROUND & AIMS

Oral immunization with Helicobacter pylori urease can cure Helicobacter infection in animals. As a step toward therapeutic immunization in humans, the safety and immunogenicity of oral immunization with recombinant H. pylori urease were tested in H. pylori-infected adults.

METHODS

Twenty-six H. pylori-infected volunteers were randomized in a double-blind study to four weekly oral doses of 180, 60, or 20 mg of urease with 5 microg heat-labile enterotoxin of Escherichia coli (LT), LT alone, or placebo. Side effects and immune responses were evaluated weekly after immunization, and gastric biopsy specimens were obtained after 1 month and 6 months for histology and quantitative cultures.

RESULTS

Diarrhea was noted in 16 of 24 (66%) of the volunteers who completed the study. Antiurease serum immunoglobulin A titers increased 1. 58-fold +/- 0.37-fold and 3.66-fold +/- 1.5-fold (mean +/- SEM) after immunization with 60 and 180 mg urease, respectively, whereas no change occurred in the placebo +/- LT groups (P = 0.005). Circulating antiurease immunoglobulin A-producing cells increased in volunteers exposed to urease compared with placebo (38.9 +/- 13. 6/10(6) vs. 5.4 +/- 3.1; P = 0.018). Eradication of H. pylori infection was not observed, but urease immunization induced a significant decrease in gastric H. pylori density.

CONCLUSIONS

H. pylori urease with LT is well tolerated and immunogenic in H. pylori-infected individuals. An improved vaccine formulation may induce curative immunity.

Coactivators and TAFs of transcription activation in wheat

Transcription regulation often activates quiescent genes in a tissue-specific or developmental manner. Activator proteins bind to a DNA sequence upstream of the promoter, interact with the general transcription proteins via bridging proteins, and elevate transcription levels. One group of bridging proteins, the coactivators, have been characterized in animals as polypeptides tightly associated with the general transcription factor TATA-binding protein (TBP). They are referred to as TAFs (TBP-associated factors), and together with TBP comprise general transcription factor IID. We provide biochemical evidence that wheat IID contains coactivators. An activator protein with an acidic activation domain facilitates the binding of IID to the template, and potentiates activated in vitro transcription with wheat IID, but not with wheat TBP. Using antibodies to wheat TBP, we demonstrate that wheat IID also contains TAFs. This is the first demonstration that a plant contains coactivators and TAFs.

Dual diagnosis subtypes in urban substance abuse and mental health clinics

OBJECTIVES

This study sought to determine rates of dual disorders (psychiatric and substance use disorders) in a population of low-income inner-city outpatients, to compare the rates in outpatient mental health and substance abuse treatment settings, and to examine the clinical usefulness of classifying patients with dual disorders into three subtypes.

METHODS

A total of 57 low-income urban residents receiving mental health treatment and 73 receiving substance abuse treatment were given semistructured clinical interviews to ascertain lifetime and concurrent DSM-III-R axis I disorders. Patients with dual disorders were classified into subtypes depending on whether their psychiatric or substance use disorder was caused by the comorbid disorder or whether both disorders existed independently.

RESULTS

Eighty-three patients had a lifetime history of dual disorders: 34 patients (60 percent) in the mental health settings and 49 (67 percent) in substance abuse treatment. Among the 83 with dual disorders, more than half had experienced symptoms of both disorders within the past year. Each of the disorders was considered primary (that is, no indication was found that one was caused by the other) for 24 patients in the mental health settings (71 percent) and 31 in the substance abuse treatment settings (63 percent).

CONCLUSIONS

In each type of treatment setting, nearly two-thirds of the patients met criteria for a lifetime diagnosis of a dual disorder. This high rate of comorbidity did not appear to be attributable to substance use causing psychiatric symptoms, or vice versa. The high rate suggests the need for greater integration of mental health and substance abuse treatment, regardless of setting.

Rheumatoid factor idiotypic and antigenic specificity is strongly influenced by the light chain VJ junction

The aim of this study was to define the structural basis for rheumatoid factor (RF) specificity and for the expression of the RF light chain-associated Ids, 4C9 and 6B6.6, by determining the reactivity of recombined heavy and light chains of Ig derived from monoclonal B cell lines of patients with rheumatoid arthritis and of light chains with site-directed mutations. We found that expression of the 4C9 and 6B6.6 Ids resulted from use of the VkIIIa genes Humkv 328 and Vg, but only in the presence of a permissive VJ junction. Expression of the Ids was independent of heavy chain use for the Humkv328-encoded light chains, but was highly dependent on the associated heavy chain for the Vg-encoded light chains. The RF specificity of the Abs was primarily heavy chain dependent, but the light chain VJ junction was critical in determining the relative avidity of the Abs for Fc. Our study points to the critical contribution of the somatically generated VJ junction to RF autoantibody specificity and to the expression of the two RF-associated Ids studied.

Postprandial sleep in healthy men

Twenty-one healthy men between 18 and 30 years of age were studied to determine the effects of midday food intake on sleep. Twelve subjects were administered liquid carbohydrate meals at lunchtime on 2 consecutive days. Subjects slept on 22 of the 24 study days for an average of 93 minutes during 3 hours of postprandial polysomnographic recording. Nine subjects were used as controls and were deprived of a lunch meal. Six of the nine subjects slept for an average of 30 minutes during the postprandial period. This time was significantly shorter than that of subjects in the meal condition (p < 0.005). There was no difference in latency to sleep onset following food intake between the two study groups. The results of this study suggest that lunchtime food intake does not promote the initiation of sleep, but that it does increase the duration of sleep episodes occurring during the postprandial period.
