RESUMO

The COVID-19 pandemic highlighted the need for potent community-based tools to improve preparedness. We developed a community health-safety climate (HSC) measure to assess readiness to adopt health behaviors during a pandemic. We conducted a mixed-methods study incorporating qualitative methods (e.g., focus groups) to generate items for the measure and quantitative data from a February 2021 national survey to test reliability, multilevel construct, and predictive and nomologic validities. The 20-item HSC measure is unidimensional (Cronbach α = 0.87). All communities had strong health-safety climates but with significant differences between communities (F = 10.65; p<0.001), and HSC levels predicted readiness to adopt health-safety behaviors. HSC strength moderated relationships between HSC level and behavioral indicators; higher climate homogeneity demonstrated stronger correlations. The HSC measure can predict community readiness to adopt health-safety behaviors in communities to inform interventions before diseases spread, providing a valuable tool for public health authorities and policymakers during a pandemic.

RESUMO

Interleukin 22 (IL-22) is a member of the IL-10 cytokine family that is involved in inflammatory and wound healing processes. Originally considered a T helper type 1 (T(H)1)-associated cytokine, IL-22 has since been shown to be produced mainly by IL-17-producing helper T cells (T(H)-17 cells). Here we describe a previously uncharacterized IL-22-producing human helper T cell population that coexpressed the chemokine receptor CCR6 and the skin-homing receptors CCR4 and CCR10. These cells were distinct from both T(H)-17 cells and T(H)1 cells. Downregulation of either the aryl hydrocarbon receptor (AHR) or the transcription factor RORC by RNA-mediated interference affected IL-22 production, whereas IL-17 production was affected only by downregulation of RORC by RNA-mediated interference. AHR agonists substantially altered the balance of IL-22- versus IL-17-producing cells. This subset of IL-22-producing cells may be important in skin homeostasis and pathology.

RESUMO

Mental health informatics studies methods that collect, model, and interpret a wide variety of data to generate useful information with theoretical or clinical relevance to improve mental health and mental health care. This article presents a mental health informatics approach that is based on the decision-making theory of depression, whereby daily life data from a natural sequential decision-making task are collected and modeled using a reinforcement learning method. The model parameters are then estimated to uncover specific aspects of decision-making impairment in individuals with depression. Empirical results from a pilot study conducted to examine decision-making impairments in the daily lives of university students with depression are presented to illustrate this approach. Future research can apply and expand on this approach to investigate a variety of daily life situations and psychiatric conditions and to facilitate new informatics applications. Using this approach in mental health research may generate useful information with both theoretical and clinical relevance and high ecological validity.

RESUMO

Lymphoid tissue inducer cells are members of an emerging family of innate lymphoid cells (ILC). Although these cells were originally reported to produce cytokines such as interleukin-17 (IL-17) and IL-22, we demonstrate here that human CD127(+)RORC(+) and CD56(+)CD127(+) LTi-like ILC also express IL-2, IL-5, and IL-13 after activation with physiologic stimuli such as common γ-chain cytokines, Toll-like receptor (TLR) 2 ligands, or IL-23. Whereas TLR2 signaling induced IL-5, IL-13, and IL-22 expression in a nuclear factor κB (NF-κB)-dependent manner, IL-23 costimulation induced only IL-22 production. CD127(+) LTi-like ILC displayed clonal heterogeneity for IL-13 and IL-5 production, suggesting in vivo polarization. Finally, we identified a role for autocrine IL-2 signaling in mediating the effects of TLR2 stimulation on CD56(+)CD127(+) and CD127(+) LTi-like ILC. These results indicate that human LTi-like ILC can directly sense bacterial components and unravel a previously unrecognized functional heterogeneity among this important population of innate lymphoid cells.

RESUMO

The psychological effects of war represent a growing public health concern as more refugees and asylum seekers migrate across borders. This study investigates whether sociodemographic, premigration and postmigration, and psychosocial factors predict adverse psychiatric symptoms in refugees and asylum seekers exposed to torture (N = 278). Hierarchical linear regressions revealed that female sex, older age, and unstable housing predicted greater severity of anxiety, posttraumatic stress disorder (PTSD), and depression. Cumulative exposure to multiple torture types predicted anxiety and PTSD, while mental health, basic resources (access to food, shelter, medical care), and external risks (risk of being victimized at home, community, work, school) were the strongest psychosocial predictors of anxiety, PTSD, and depression. Also, time spent in the United States before presenting for services significantly predicted anxiety, PTSD, and depression. Consequently, public-sector services should seek to engage this high-risk population immediately upon resettlement into the host country using a mental health stepped care approach.

RESUMO

BACKGROUND/AIMS: Trust is the cornerstone of clinical trial recruitment and retention. Efforts to decrease barriers and increase clinical trial participation among diverse populations have yielded modest results. There is an urgent need to better understand the complex interactions between trust and clinical trial participation. The process of trust-building has been a focus of intense research in the business community. Yet, little has been published about trust in oncology clinical trials or the process of building trust in clinical trials. Both clinical trials and business share common dimensions. Business strategies for building trust may be transferable to the clinical trial setting. This study was conducted to understand and utilize contemporary thinking about building trust to develop an Integrated Model of Trust that incorporates both clinical and business perspectives. METHODS: A key word-directed literature search of the PubMed, Medline, Cochrane, and Google Search databases for entries dated between 1 January 1985 and 1 September 2015 was conducted to obtain information from which to develop an Integrated Model of Trust. RESULTS: Successful trial participation requires both participants and clinical trial team members to build distinctly different types of interpersonal trust to effect recruitment and retention. They are built under conditions of significant emotional stress and time constraints among people who do not know each other and have never worked together before. Swift Trust and Traditional Trust are sequentially built during the clinical trial process. Swift trust operates during the recruitment and very early active treatment phases of the clinical trial process. Traditional trust is built over time and operates during the active treatment and surveillance stages of clinical trials. The Psychological Contract frames the participants' and clinical trial team members' interpersonal trust relationship. The "terms" of interpersonal trust are negotiated through the psychological contract. Contract renegotiation occurs in response to cyclical changes within the trust relationship throughout trial participation. CONCLUSION: The Integrated Model of Trust offers a novel framework to interrogate the process by which diverse populations and clinical trial teams build trust. To our knowledge, this is the first model of trust-building in clinical trials that frames trust development through integrated clinical and business perspectives. By focusing on the process, rather than outcomes of trust-building diverse trial participants, clinical trials teams, participants, and cancer centers may be able to better understand, measure, and manage their trust relationships in real time. Ultimately, this may foster increased recruitment and retention of diverse populations to clinical trials.

RESUMO

BACKGROUND: Nurses, social workers, and medical residents are ethically mandated to engage in policy advocacy to promote the health and well-being of patients and increase access to care. Yet, no instrument exists to measure their level of engagement in policy advocacy. RESEARCH OBJECTIVE: To describe the development and validation of the Policy Advocacy Engagement Scale, designed to measure frontline healthcare professionals' engagement in policy advocacy with respect to a broad range of issues, including patients' ethical rights, quality of care, culturally competent care, preventive care, affordability/accessibility of care, mental healthcare, and community-based care. RESEARCH DESIGN: Cross-sectional data were gathered to estimate the content and construct validity, internal consistency, and test-retest reliability of the Policy Advocacy Engagement Scale. Participants and context: In all, 97 nurses, 94 social workers, and 104 medical residents (N = 295) were recruited from eight acute-care hospitals in Los Angeles County. Ethical considerations: Informed consent was obtained via Qualtrics and covered purposes, risks and benefits; voluntary participation; confidentiality; and compensation. Institutional Review Board approval was obtained from the University of Southern California and all hospitals. FINDINGS: Results supported the validity of the concept and the instrument. In confirmatory factor analysis, seven items loaded onto one component with indices indicating adequate model fit. A Pearson correlation coefficient of .36 supported the scale's test-retest stability. Cronbach's α of .93 indicated strong internal consistency. DISCUSSION: The Policy Advocacy Engagement Scale demonstrated satisfactory psychometric properties in this initial test. Findings should be considered within the context of the study's limitations, which include a low response rate and limited geographic scope. CONCLUSION: The Policy Advocacy Engagement Scale appears to be the first validated scale to measure frontline healthcare professionals' engagement in policy advocacy. With it, researchers can analyze variations in professionals' levels of policy advocacy engagement, understand what factors are associated with it, and remedy barriers that might exist to their provision of it.

RESUMO

This study aims to describe the factors that predict health professionals' engagement in policy advocacy. The researchers used a cross-sectional research design with a sample of 97 nurses, 94 social workers, and 104 medical residents from eight hospitals in Los Angeles. Bivariate correlations explored whether seven predictor scales were associated with health professionals' policy advocacy engagement and revealed that five of the eight factors were significantly associated with it (p < .05). The factors include patient advocacy engagement, eagerness, skills, tangible support, and organizational receptivity. Regression analysis examined whether the seven scales, when controlling for sociodemographic variables and hospital site, predicted levels of policy advocacy engagement. Results revealed that patient advocacy engagement (p < .001), eagerness (p < .001), skills (p < .01), tangible support (p < .01), perceived effectiveness (p < .05), and organizational receptivity (p < .05) all predicted health professional's policy advocacy engagement. Ethical commitment did not predict policy advocacy engagement. The model explained 36% of the variance in policy advocacy engagement. Limitations of the study and its implications for future research, practice, and policy are discussed.

RESUMO

PURPOSE: To investigate the relationships between sociodemographic, pre- and post-migration variables with prevalence of psychological distress and global functioning in a heterogeneous sample of torture survivors. METHODS: Clients referred from resettlement agencies via the Office of Refugee Resettlement (ORR) to a community clinic in the United States (N = 278) were interviewed with structured, translated questionnaires. Univariate and multivariate logistic regression analyses determined the associations of sociodemographic, pre-, and post-migration risk factors with posttraumatic stress disorder (PTSD), depression, anxiety, and global functioning. RESULTS: Regression data indicate that length of time between arrival in US and clinical services was significantly associated with PTSD and depression; participants receiving services after 1 year of resettlement were more likely to experience PTSD (adjusted OR = 3.29) and depression (adjusted OR = 4.50) than participants receiving services within 1 year. Anxiety was predicted by female gender (adjusted OR = 3.43), age over 40 years (adjusted OR = 3.12), Muslim religion (adjusted OR = 2.64), and receiving medical services (AOR 3.1). Severely impaired global functioning was associated with female gender (adjusted OR = 2.75) and unstable housing status (adjusted OR = 2.21). CONCLUSION: Findings highlight the importance of examining post-migration variables such as length of time in country prior to receiving services in addition to pre-migration torture history upon relocated torture survivors. Clinicians and policy-makers should be aware of the importance of early mental health screening and intervention on reducing the psychiatric burden associated with torture and forced relocation.

RESUMO

OBJECTIVE: Lifestyle interventions that promote physical activity and healthy dietary habits may reduce binge eating symptoms and be more feasible and sustainable among ethnic minority women, who are less likely to seek clinical treatment for eating disorders. The purpose of this study was to investigate (1) whether participating in a lifestyle intervention is a feasible way to decrease binge eating symptoms (BES) and (2) whether changes in BES differed by intervention (physical activity vs. dietary habits) and binge eating status at baseline (binger eater vs. non-binge eater) in African American and Hispanic women. METHOD: Health Is Power (HIP) was a longitudinal randomized controlled trial to promote physical activity and improve dietary habits. Women (N = 180) who completed anthropometric measures and questionnaires assessing fruit and vegetable and dietary fat intake, BES and demographics at baseline and post-intervention six months later were included in the current study. RESULTS: Over one-fourth (27.8%) of participants were categorized as binge-eaters. Repeated measures ANOVA demonstrated significant two- and three-way interactions. Decreases in BES over time were greater in binge eaters than in non-binge eaters (F(1,164) = 33.253, p < .001), and women classified as binge eaters who participated in the physical activity intervention reported greater decreases in BES than non-binge eaters in the dietary habits intervention (F(1,157) = 5.170, p = .024). DISCUSSION: Findings suggest behavioral interventions to increase physical activity may lead to reductions in BES among ethnic minority women and ultimately reduce the prevalence of binge eating disorder and health disparities in this population.

RESUMO

Codes of ethics of nursing, social work, and medicine, as well as Joint Commission Accreditation Standards, require members of these professions to engage in advocacy on behalf of patients. With use of expert panels, seven categories of patient problems in the healthcare milieu were identified: ethical rights, quality care, preventive care, culturally competent care, affordable/accessible care, mental health care, and care linked to patients' homes and communities. To measure the frequency with which healthcare professionals engage in patient advocacy related to these specific problems, the Patient Advocacy Engagement Scale (Patient-AES) scale was developed and validated through analysis of responses of 297 professionals (94 social workers, 97 nurses, and 104 medical residents) recruited from the personnel rosters of eight acute-care hospitals in Los Angeles County. Hospitals included public, not-for-profit, HMO, and church-affiliated hospitals that served general hospital populations, veterans, cancer patients, and children. Results supported the validity of both the concept and the instrument. Construct validity was supported by testing the hypothesized seven-factor solution through confirmatory factor analysis; 26 items loaded onto seven components. Pearson correlations for the overall scale and seven subscales in two administrations supported their test-retest stability. Cronbach α ranged from .55 to .94 for the seven subscales and .95 for the overall Patient-AES. The Patient-AES is, to our knowledge, the first scale that measures patient advocacy engagement by healthcare professionals in acute-care settings related to a broad range of specific patient problems. © 2014 Wiley Periodicals, Inc.

RESUMO

Although literature documents the need for hospital social workers, nurses, and medical residents to engage in patient advocacy, little information exists about what predicts the extent they do so. This study aims to identify predictors of health professionals' patient advocacy engagement with respect to a broad range of patients' problems. A cross-sectional research design was employed with a sample of 94 social workers, 97 nurses, and 104 medical residents recruited from eight hospitals in Los Angeles. Bivariate correlations explored whether seven scales (Patient Advocacy Eagerness, Ethical Commitment, Skills, Tangible Support, Organizational Receptivity, Belief Other Professionals Engage, and Belief the Hospital Empowers Patients) were associated with patient advocacy engagement, measured by the validated Patient Advocacy Engagement Scale. Regression analysis examined whether these scales, when controlling for sociodemographic and setting variables, predicted patient advocacy engagement. While all seven predictor scales were significantly associated with patient advocacy engagement in correlational analyses, only Eagerness, Skills, and Belief the Hospital Empowers Patients predicted patient advocacy engagement in regression analyses. Additionally, younger professionals engaged in higher levels of patient advocacy than older professionals, and social workers engaged in greater patient advocacy than nurses. Limitations and the utility of these findings for acute-care hospitals are discussed.

RESUMO

Despite increased interest in self-care for health, little consensus exists around its definition and scope. The World Health Organization has published several definitions of self-care, including in a 2019 Global Guideline rooted in sexual and reproductive health and rights (SRHR), later expanded to encompass health more generally. To establish a robust understanding of self-care, this exploratory study inventorises, consolidates, presents and analyses definitions of self-care beyond the SRHR field. A pragmatic review identified definitions and conceptualisations of self-care from peer-reviewed and grey literature published between 2009 and 2021. The search identified 91 definitions of self-care from 116 relevant publications. Data extraction informed analysis to identify recurring themes and approaches, revealing three key areas of variation: self-care being: (1) defined directly or descriptively; (2) situated within individual, interpersonal or structural contexts; (3) defined broadly or topic-specifically. A multilevel conceptualisation can guide a more broadly applicable understanding of self-care: first, as an aspect of healthcare; second, as a concept operating at individual, interpersonal and institutional levels; third, as a concept that impacts specific health fields and contexts differently. A comprehensive but adaptable framework works in service of improving health and wellbeing for all, acknowledging the linkages between self-care and health-related human rights.

RESUMO

KYV-101 is an autologous anti-CD19 chimeric antigen receptor (CAR)-T cell therapy under investigation for patients with B-cell driven autoimmune diseases. Hu19-CD828Z is a fully human anti-CD19 CAR designed and demonstrated to have a favorable clinical safety profile. Since anti-CD19 CAR T cells target and kill B cells in both circulation and tissues, the treatment with Hu19-CD828Z CAR T cells offers great potential in depleting autoreactive B cells. Demonstrate that Hu19-CD828Z CAR T cells manufactured from cryopreserved leukaphereses from patients with systemic lupus erythematosus (SLE) exhibit CAR-mediated and CD19-dependent cytokine release, proliferation and cytotoxicity when co-cultured with autologous primary B cells. T cells were enriched from cryopreserved leukaphereses from SLE patients or healthy donors (HD). CAR T cells were generated by transducing these cells with a lentiviral vector encoding Hu19-CD828Z. CAR-mediated and CD19-dependent activity was monitored in vitro in a set of cytotoxicity, cytokine release, and proliferation studies, in response to autologous primary CD19+ B cells, a CD19+ cell line (NALM-6), or a CD19- cell line (U937). Hu19-CD828Z CAR T cells produced from SLE patients or HD induced greater proliferation and dose-dependent cytotoxicity against both autologous primary B cells and the CD19+ NALM-6 cells than nontransduced control T cells or co-cultures with a CD19- cell line. Interestingly, there was lower inflammatory cytokine production from SLE patient-derived CAR T cells compared to HD donor-derived CAR T cells with either CD19+ cells or primary B cells. Hu19-CD828Z CAR T cells generated from SLE patient lymphocytes demonstrate CAR-mediated and CD19-dependent activity against autologous primary B cells with reduced inflammatory cytokine production supporting KYV-101 as a novel potential therapy for the depletion of pathogenic B cells in SLE patients.

RESUMO

We report a patient with young onset Parkinson's disease (PD) and a heterozygous point mutation in parkin (c.1000C>T; p.Arg334Cys). After 8 years he developed pyramidal signs and reinvestigation demonstrated MRI and laboratory findings supportive of a diagnosis of multiple sclerosis (MS) with a primary progressive (PP) clinical course. This is a previously un-described association of young onset PD with PPMS. Imaging clearly dates the occurrence of each disease as chronologically separate phenomena. There is not currently evidence for shared causation or pathogenesis between the two neurological disorders but we will follow with interest the emerging genetic characterization of parkin in both PD and MS.

RESUMO

BACKGROUND: Selecting effective implementation strategies to support guideline-concordant dental care is a complex process. We are drawing on data collected during the DISGO study to reflect on barriers we encountered in implementing a deliberative engagement process for discussing implementation strategies relevant to the evidence-based guideline targeted in this intervention. The goal is to identify factors that may influence the success of deliberative engagement as a technique to involve healthcare staff in identifying priorities for implementation strategies. METHODS: We drew on online chat transcripts from the deliberative engagement forums collected during the DISGO study. The chat transcripts were automatically generated for each discussion and captured the written exchanges between participants and moderators in all participating dental clinics. Chat transcripts were analyzed following a content analysis approach. RESULTS: Our findings revealed barriers to the successful implementation of deliberative engagement in the context of the DISGO study. Participants were not familiar with the materials that had been prepared for the forum and lacked familiarity with the topic of deliberation. Participants also did not share divergent viewpoints and reinforced existing ideas rather than introducing new ideas. CONCLUSIONS: In order to ensure that obstacles that were encountered in this study are not repeated, it is important to carefully consider how staff can effectively be prepared for the deliberations. Participants must be familiar with the content of the guideline, and most questions about the content and evidence should be answered before the deliberative engagement sessions. If perspectives among staff on a guideline are homogenous, briefing materials should introduce perspectives that complement existing views among staff. It is also necessary to create an environment in which staff are comfortable introducing opinions that may not be held by the majority of colleagues. TRIAL REGISTRATION: This project is registered at ClinicalTrials.gov with ID NCT04682730. The trial was first registered on 12/18/2020. https://clinicaltrials.gov/ct2/show/NCT04682730 .

RESUMO

Background: Dental caries affects billions worldwide and in the U.S. is among the most prevalent noncommunicable diseases in both children and adults. Early in the caries process, it can be arrested by dental sealants, which are non-invasive and thus tooth sparing, however, few dentists have adopted this approach. Deliberative engagement processes enable participants to engage with diverse perspectives on a policy issue and develop and share with policy makers informed opinions about the policy issue. We examined the effects of a deliberative engagement process on the ability of oral health providers to endorse implementation interventions and to apply dental sealants. Methods: Using a stepped wedge design, 16 dental clinics were cluster randomized, and 680 providers and staff were exposed to a deliberative engagement process that included an introductory session, workbook, facilitated small group deliberative forum, and post-forum survey. Forum participants were assigned to forums to ensure diverse role representation. Mechanisms of action examined included sharing voice and diversity of opinion. Three months after each clinic's forum, the clinic manager was interviewed about implementation interventions deployed. There were 98 clinic-months in the non-intervention period and 101 clinic-months in the intervention period. Results: Compared with providers and staff in small clinics, providers and staff in medium and large clinics more strongly agreed that their clinic should adopt two of the three proposed implementation interventions targeting the first barrier and one of the two proposed implementation interventions targeting the second barrier. Compared with the non-intervention period, in the intervention period providers did not place more sealants on occlusal non-cavitated carious lesions. Survey respondents reported sharing both promotive and prohibitive voice. From the beginning to the end of the forums, most forum participants did not change their opinions about the possible implementation interventions. At the end of the forums, there was no significant within-group variability in implementation interventions endorsed. Conclusions: Deliberative engagement intervention may help clinic leadership identify implementation interventions when there is a challenging problem, a network of semi-autonomous clinics, and autonomous providers within those clinics. It remains to be determined whether there is a range of perspectives within clinics. Trial Registration: This project is registered at ClinicalTrials.gov with ID NCT04682730.

RESUMO

OBJECTIVES: Selecting effective implementation strategies to support guideline-concordant dental care is a complex process. For this research project, an online deliberative forum brought together staff from dental clinics to discuss the strengths and weaknesses of implementation strategies and barriers to implementation of a component of a dental (pit-and-fissure) guideline. The goal was to determine whether deliberative engagement enabled participants' sharing of promotive and prohibitive voice about implementation strategies to promote guideline-concordant care. DESIGN: Qualitative analysis of online chat transcripts of facilitated deliberations from 31 small group sessions. SETTING: Kaiser Permanente Dental (KP Dental) in the USA. PARTICIPANTS: All staff from 16 dental offices. RESULTS: The directed content analysis revealed that participants shared prohibitive and promotive voice when offering critique of the barriers and the implementation strategies suggested by the researchers. The analysis also revealed that the focus of the deliberations often was not on the aspect of the pit-and-fissure guideline intended by the research team for deliberation. CONCLUSIONS: The deliberative forum discussions were a productive venue to ask staff in dental clinics to share their perspectives on strategies to promote guideline-concordant care as well as barriers. Participants demonstrated prohibitive voice and engaged critically with the materials the research team had put together. An important limitation of the deliberation was that the discussion often centred around an aspect of the pit-and-fissure guideline that already was implemented well. To ensure a deliberation oriented towards resolving challenging aspects of the pit-and-fissure guideline, greater familiarity with the guideline would have been important, as well as more intimate knowledge of the current discrepancies in guideline-concordant care. TRIAL REGISTRATION NUMBER: This project is registered at ClinicalTrials.gov with ID NCT04682730. The trial was first registered on 18 December 2020. https://clinicaltrials.gov/ct2/show/NCT04682730.

RESUMO

BACKGROUND: Physical activity (PA) is known to improve quality of life (QoL) as well as reduce mortality and disease progression in individuals with chronic neurological disorders. However, Latina women are less likely to participate in recommended levels of PA due to common socioeconomic barriers, including limited resources and access to exercise programs. Therefore, we developed a community-based intervention with activity monitoring and behavioral coaching to target these barriers and facilitate sustained participation in an exercise program promoting PA. OBJECTIVE: The aim of this study was to determine the feasibility and efficacy of a community-based intervention to promote PA through self-monitoring via a Fitbit and behavioral coaching among Latina participants with chronic neurological disorders. METHODS: We conducted a proof-of-concept study among 21 Spanish-speaking Latina participants recruited from the Los Angeles County and University of Southern California (LAC+USC) neurology clinic; participants enrolled in the 16-week intervention at The Wellness Center at The Historic General Hospital in Los Angeles. Demographic data were assessed at baseline. Feasibility was defined by participant attrition and Fitbit adherence. PA promotion was determined by examining change in time spent performing moderate-to-vigorous PA (MVPA) over the 16-week period. The effect of behavioral coaching was assessed by quantifying the difference in MVPA on days when coaching occurred versus on days without coaching. Change in psychometric measures (baseline vs postintervention) and medical center visits (16 weeks preintervention vs during the intervention) were also examined. RESULTS: Participants were of low socioeconomic status and acculturation. A total of 19 out of 21 (90%) participants completed the study (attrition 10%), with high Fitbit wear adherence (mean 90.31%, SD 10.12%). Time performing MVPA gradually increased by a mean of 0.16 (SD 0.23) minutes per day (P<.001), which was equivalent to an increase of approximately 18 minutes in MVPA over the course of the 16-week study period. Behavioral coaching enhanced intervention effectiveness as evidenced by a higher time spent on MVPA on days when coaching occurred via phone (37 min/day, P=.02) and in person (45.5 min/day, P=.01) relative to days without coaching (24 min/day). Participants improved their illness perception (effect size g=0.30) and self-rated QoL (effect size g=0.32). Additionally, a reduction in the number of medical center visits was observed (effect size r=0.44), and this reduction was associated with a positive change in step count during the study period (P.=04). CONCLUSIONS: Self-monitoring with behavioral coaching is a feasible community-based intervention for PA promotion among Latina women of low socioeconomic status with chronic neurological conditions. PA is known to be important for brain health in neurological conditions but remains relatively unexplored in minority populations.

RESUMO

Intelligent data capture is an application that can provide electronic access to data contained in any type of document, including clinical records and financial documents, thereby reducing or eliminating the need for manual data entry. Before implementing this technology, however, healthcare leaders should: Evaluate technology in the context of a business case to ensure a measurable ROI. Communicate with employees throughout the process so they are prepared for and embrace the inevitable changes that will come with automation. Implement the solution in phases, focusing on those document types that can deliver for a safer, less disruptive approach. Achieve maximum benefit to the organization by reengineering business processes to fully leverage technology rather than simply automating existing manual processes.
