Communities organizing to promote equity: engaging local communities in public health responses to health inequities exacerbated by COVID-19-protocol paper

Background

The COVID-19 pandemic has disproportionately impacted rural and under-resourced urban communities in Kansas. The state's response to COVID-19 has relied on a highly decentralized and underfunded public health system, with 100 local health departments in the state, few of which had prior experience engaging local community coalitions in a coordinated response to a public health crisis.

Methods

To improve the capacity for local community-driven responses to COVID-19 and other public health needs, the University of Kansas Medical Center, in partnership with the Kansas Department of Health and Environment, will launch Communities Organizing to Promote Equity (COPE) in 20 counties across Kansas. COPE will establish Local Health Equity Action Teams (LHEATs), coalitions comprised of community members and service providers, who work with COPE-hired community health workers (CHWs) recruited to represent the diversity of the communities they serve. CHWs in each county are tasked with addressing unmet social needs of residents and supporting their county's LHEAT. LHEATs are charged with implementing strategies to improve social determinants of health in their county. Monthly, LHEATs and CHWs from all 20 counties will come together as part of a learning collaborative to share strategies, foster innovation, and engage in peer problem-solving. These efforts will be supported by a multilevel communications strategy that will increase awareness of COPE activities and resources at the local level and successes across the state. Our mixed methods evaluation design will assess the processes and impact of COPE activities as well as barriers and facilitators to implementation using aspects of both the Consolidated Framework for Implementation Research (CFIR) and Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) models.

Discussion

This protocol is designed to expand community capacity to strategically partner with local public health and social service partners to prioritize and implement health equity efforts. COPE intentionally engages historically resilient communities and those living in underserved rural areas to inform pragmatic strategies to improve health equity.

The Impact of the COVID-19 Pandemic on Patient Disparities in Long-Term Opioid Therapy

BACKGROUND

The COVID-19 pandemic disrupted how primary care patients with chronic pain received care. Our study sought to understand how long-term opioid therapy (LtOT) for chronic pain changed over the course of the pandemic overall and for different demographic subgroups.

METHODS

We used data from electronic health records of 64 primary care clinics across Washington state and Idaho to identify patients who had a chronic pain diagnosis and were receiving long-term opioid therapy. We defined 10-month periods in 2019 to 2021 as prepandemic, early pandemic and late pandemic and used generalized estimating equations analysis to compare across these time periods and demographic characteristics.

RESULTS

We found a proportional decrease in LtOT for chronic pain in the early months of the pandemic (OR = 0.94, P = .007) followed by an increase late pandemic (OR = 1.08, P = .002). Comparing late pandemic to prepandemic, identifying as Asian or Black, having fewer comorbidities, or living in an urban area were associated with higher likelihood of being prescribed LtOT.

DISCUSSION

The use of LtOT for chronic pain in primary care has increased from before to after the COVID-19 pandemic with racial/ethnic and geographic disparities. Future research is needed to understand these disparities in LtOT and their effect on patient outcomes.

Refugee and migrants' involvement in participatory spaces in a US practice-based research network study: Responding to unanticipated priorities

BACKGROUND

Refugees and migrants face suboptimal involvement in spaces for primary healthcare decision-making. Given the rising numbers of resettled refugees and migrants in primary care settings in the United States, there is an urgent need for patient-centred outcome research in practice-based research networks (PBRNs) with diverse ethnolinguistic communities. This study explored whether researchers, clinicians and patients would achieve consensus on (1) a common set of clinical problems that were applicable across a PBRN and (2) potential clinical interventions to address those problems to inform a patient-centred outcomes research (PCOR) study in a similar research network.

METHODS

In this qualitative participatory health research study, patients from diverse ethnolinguistic communities and clinicians from seven practices in a US PBRN discussed preferences for PCOR responsive to patients and the clinicians who serve them in language-discordant settings. Researchers and an advisory panel that included patients and clinicians from each participating practice held regular advisory meetings to monitor progress on project milestones and solve emerging problems. Participants took part in 10 sessions using Participatory Learning in Action and the World Café methods to identify and prioritise their ideas, using questions set for them by the advisory panel. Data were analysed based on principles of qualitative thematic content analysis.

RESULTS

Participants identified common barriers in language-discordant healthcare settings, principally patient-clinician communication barriers and suggestions to overcome these barriers. A key finding was an unanticipated consensus about the need for attention to healthcare processes rather than a clinical research priority. Negotiation with research funders enabled further analysis of potential interventions for care processes to improve communication and shared decision-making in consultations and the practice as a whole.

CONCLUSION

PCOR studies should examine interventions for improving communication between patients from diverse ethnolinguistic communities and primary care staff if the sorts of harms experienced by patients experiencing language-discordant healthcare are to be reduced or prevented. Flexibility and responsiveness from funders to unanticipated findings are key structural supports for participatory health research in primary care clinical settings with this population and others who experience marginalisation and exclusion.

PATIENT OR PUBLIC CONTRIBUTION

Patients and clinicians participated in the study both in the formulation of the study question, data collection, analysis and dissemination of these results; consented to their individual participation; and reviewed early drafts of the manuscript.

Assessing Social Needs and Engaging Community Health Workers in Underserved Kansas Counties: Insights From Primary Care Providers and Clinic Managers

INTRODUCTION

Rural and under-resourced urban communities face unique challenges in addressing patients' social determinants of health needs (SDoH). Community health workers (CHWs) can support patients experiencing social needs, yet little is known about how rural and under-resourced primary care clinics are screening for SDoH or utilizing CHWs.

METHODS

Interviews were conducted with primary care clinic providers and managers across a geographically large and predominately rural state to assess screening practices for SDoH and related community resources, and perspectives on using CHWs to address SDoH. Interviews were conducted by phone, recorded, and transcribed. Data were analyzed using thematic analysis. We completed interviews with 27 respondents (12 providers and 15 clinic managers) at 26 clinics.

RESULTS

Twelve (46.1%) clinics had a standardized process for capturing SDoH, but this was primarily limited to Medicare wellness visits. Staffing and time were identified as barriers to proper SDoH screening. Lack of transportation and affordable medication were the most cited SDoH. While respondents were all aware of CHWs, only 8 (30.8%) included a CHW on their care team. Perceived barriers to engaging CHWs included cost, space, and availability of qualified CHWs. Perceived benefits of engaging CHWs in their practice were: assisting patients with navigating resources and programs, relieving clinical staff of non-medical tasks, and bridging language barriers.

CONCLUSIONS

Rural and under-resourced primary care clinics need help in identifying and addressing SDoH. CHWs could play an important part in addressing social needs and promoting preventive care if financial constraints could be addressed and local CHWs could be trained.

Understanding Medication Adherence in Bhutanese Refugees With Diabetes in a Midwestern City

Introduction:

Bhutanese refugees have a higher prevalence of type 2 diabetes but are less likely to achieve medication adherence and glycemic control. The purpose of this project was to understand factors affecting diabetes medication adherence in this population.

Methodology:

This was a qualitative project using focus groups of adult Bhutanese refugees with type 2 diabetes ≥18 years old and hemoglobin A1C ≥8% and their caregivers from a family medicine clinic at the University of Kansas. Data were analyzed using content analysis.

Results:

A total of 23 individuals participated. Three themes emerged from data analysis: desire to engage in care but face multiple barriers, family and community support invaluable for health, and considerations for culturally contextual person-centered care. Participants provided specific recommendations to address the barriers, with emphasis on improving health literacy.

Discussion:

Integrating the identified factors can foster person-centered, culturally congruent care to improve diabetes medication adherence in Bhutanese refugees.

The impact of economic recession on the health of migrant fathers over time: results from the Growing up in Ireland longitudinal study

Background

The relationship between economic conditions and health can depend on both the health outcome measured and the composition of the population. Analysis of outcomes by both ethnicity and country of birth has been recommended. The aim of our study is to explore the impact of recession on self-rated health and depression of migrant fathers in Ireland over time, considering both ethnicity and country of birth.

Methods

Longitudinal data from waves of a population-representative cohort study (Growing up in Ireland, 2008–2013) was used with Wave 1 collected before the recession and Wave 2 collecting information on how the recession affected families. Socio-demographic variables, self-rated health and depression were compared across three groups of fathers classified by self-identified ethnicity and country of birth: White Irish (n = 5628), Other White European (EU-10) (n = 431), and Black African (n = 192) using chi-square tests and logistic regression models. Rates of follow-up were compared across groups at Wave 3.

Results

Prior to the recession, the rate of employment was lowest for African fathers (51% vs 81% for EU-10 fathers and 92% for Irish fathers, p < 0.001). At Wave 2, African families were more likely to have experienced a very significant effect of the recession (40.1% compared to 22.4% for families from EU-10 and 21.3% for Irish families, p < 0.001). However, the impact of the recession on depression and self-rated health was only found in Irish fathers. By Wave 3, rates of follow-up were lower for migrant fathers, particularly for EU-10 fathers.

Conclusions

Understanding the relationship between economic conditions and health is complex and may be related to multiple dimensions of socio-economic advantage and disadvantage. African families were already more likely to be disadvantaged prior to the recession and that pattern persisted during the recession. Further research on attrition rates of migrants in population cohort studies is needed and the development of effective strategies for recruitment, follow-up and analysis.

'If relevant, yes; if not, no': General practitioner (GP) users and GP perceptions about asking ethnicity questions in Irish general practice: A qualitative analysis using Normalization Process Theory

Context

The use of ethnic identifiers in health systems is recommended in several European countries as a means to identify and address heath inequities. There are barriers to implementation that have not been researched.

Objective

This study examines whether and how ethnicity data can be collected in Irish general practices in a meaningful and acceptable way.

Methods

Qualitative case study data generation was informed by Normalization Process Theory (NPT) constructs about ‘sense’ making and ‘engagement’. It consisted of individual interviews and focus group discussions based on visual participatory techniques. There were 70 informants, including 62 general practitioner (GP) users of diverse ethnic backgrounds recruited through community organisations and eight GPs identified through an inter-agency steering group. Data were analysed according to principles of thematic analysis using NPT.

Results

The link between ethnicity and health was often considered relevant because GP users grasped connections with genetic (skin colour, lactose intolerance), geographic (prevalence of disease, early years exposure), behavioural (culture/food) and social determinant (housing) factors. The link was less clear with religion. There was some scepticism and questions about how the collection of data would benefit GP consultations and concerns regarding confidentiality and the actual uses of these data (e.g. risk of discrimination, social control). For GPs, the main theme discussed was relevance: what added value would it bring to their consultations and was it was their role to collect these data? Their biggest concern was about data protection issues in light of the European Union (EU) General Data Protection Regulation (GDPR). The difficulty in explaining a complex concept such as ‘ethnicity’ in the limited time available in consultations was also worrying.

Conclusions

Implementation of an ethnicity identifier in Irish general practices will require a strong rationale that makes sense to GP users, and specific measures to ensure that its benefits outweigh any potential harm. This is in line with both our participants’ views and the EU GDPR.

Participatory health research with migrants: Opportunities, challenges, and way forwards

CONTEXT

Migration is one of the most politically pressing issues of the 21st century but migrant health remains an under-researched area. The International Collaboration for Participatory Health Research (ICPHR) working group on migration developed this position statement to address opportunities and challenges in relation to migrant health. It aims to contribute to a shift from a deficit model that sees migrants as passively affected by policies to their reconceptualization as citizens who are engaged in the co-creation of solutions.

METHODS

This paper examines the opportunities and challenges posed by the use of PHR with migrants. It draws on a broad literature to provide examples of successful PHR with migrants and highlights critical issues for consideration.

FINDINGS

Successful initiatives illustrate the value of engaging migrants in the definition of the research agenda, the design and implementation of health interventions, the identification of health-protective factors and the operationalization and validation of indicators to monitor progress. Within increasingly super diverse contexts, fragmented community landscapes that are not necessarily constructed along ethnicity traits, inadequate structures of representation, local tensions and operational barriers can hamper meaningful PHR with migrants.

CONCLUSION

For each research context, it is essential to gauge the 'optimal' level and type of participation that is more likely to leverage migrants' empowerment. The development of Monitoring and Evaluation tools and methodological strategies to manage inter-stakeholder discrepancies and knowledge translation gaps are steps in this direction.

PATIENT OR PUBLIC CONTRIBUTION

This paper draws from contributions of migrant populations and other stakeholders to policymaking.

Participatory implementation research in the field of migrant health: Sustainable changes and ripple effects over time

Objective

This study aimed to explore whether positive impacts were sustained and unanticipated ripple effects had occurred four years after the implementation of interventions to improve cross‐cultural communication in primary care.

Background

Sustaining the implementation of change using complex interventions is challenging. The EU‐funded “RESTORE” study implemented guidelines and training on cross‐cultural communication in five Primary Care sites in Europe, combining implementation theory (Normalisation Process Theory) with participatory methodology (participatory learning and action—PLA). There were positive impacts on knowledge, skills and clinical routines.

Design, setting and participants

Four of the five original sites (England, Ireland, Greece, The Netherlands) were available for this qualitative follow‐up study. The study population (N = 44) was primary healthcare staff and migrants, most of whom had participated in RESTORE.

Intervention; main outcome measures

PLA‐style focus groups and interviews explored routine practice during consultations with migrants. Etic cards based on the effects of RESTORE stimulated the discussion. Deductive framework analysis was performed in each country followed by comparative data analysis and synthesis.

Results

Changes in knowledge, attitudes and behaviour with regard to consultations with migrants were sustained and migrants felt empowered by their participation in RESTORE. There were ongoing concerns about macro level factors, like the political climate and financial policies, negatively affecting migrant healthcare.

Conclusion

There were sustained effects in clinical settings, and additional unanticipated positive ripple effects, due in part, from the participatory approach employed.

Engaging with communities, engaging with patients: amendment to the NAPCRG 1998 Policy Statement on Responsible Research With Communities

BACKGROUND

In 1998, the North American Primary Care Research Group (NAPCRG) adopted a groundbreaking Policy Statement endorsing responsible participatory research (PR) with communities. Since that time, PR gained prominence in primary care research.

OBJECTIVES

To reconsider the original 1998 Policy Statement in light of increased uptake of PR, and suggest future directions and applications for PR in primary care. This work contributed to an updated Policy Statement endorsed by NAPCRG in 2015.

METHODS

32 university and 30 community NAPCRG-affiliated research partners, convened a workshop to document lessons learned about implementing processes and principles of PR. This document emerged from that session and reflection and discussion regarding the original Policy Statement, the emerging PR literature, and our own experiences.

RESULTS

The foundational principles articulated in the 1998 Policy Statement remain relevant to the current PR environment. Lessons learned since its publication include that the maturation of partnerships is facilitated by participatory processes that support increased community responsibility for research projects, and benefits generated through PR extend beyond research outcomes. Future directions that will move forward the field of PR in primary care include: (i) improve assessment of PR processes to better delineate the links between how PR teams work together and diverse PR outcomes, (ii) increase the number of models incorporating PR into translational research from project inception to dissemination, and (iii) increase application of PR approaches that support patient engagement in clinical settings to patient-provider relationship and practice change research.

CONCLUSION

PR has markedly altered the manner in which primary care research is undertaken in partnership with communities and its principles and philosophies continue to offer means to assure that research results and processes improve the health of all communities.

Tokenism in patient engagement

BACKGROUND

Patient engagement throughout research is a way to generate more relevant patient-important research questions, methods and results with the ultimate aim of facilitating translation of research into practice. Tokenism is defined as the practice of making perfunctory or symbolic efforts to engage communities or patients.

OBJECTIVE

We wanted to explore how tokenism might influence engaging patients in research to help researchers work towards more genuine engagement.

METHODS

The Community Clinician Advisory Group and Patient and Clinician Engagement program held a workshop at the 2015 North American Primary Care Research Group meeting titled 'How Do We Move beyond Tokenism in Patient Engagement?' Patients, clinicians and academic researchers contributed examples of genuine and token engagement characteristics based on personal experience and knowledge. Data were iteratively collated and categorized into domains and items.

RESULTS

Examples of genuine and token engagement were categorized into three domains: Methods/Structure of engagement, Intent and Relationship building. Members with experience in patient-engaged research projects felt that longitudinal engagement was a key element to effectively translating research into local community and practice.

CONCLUSIONS

The group (i) highly valued genuine intent and relationship building as elements to combat tokenism; (ii) noted that early genuine attempts at engagement may superficially resemble tokenism as researchers build enduring and trusting relationships with patient/community partners and (iii) emphasized the importance of seeking and utilizing patient experiences throughout research. These observations may contribute to more formal methods to help researchers (and reviewers) evaluate where engagement processes sit along the 'genuine-token' continuum.

Participatory methods for research prioritization in primary care: an analysis of the World Café approach in Ireland and the USA

Background

There are increasing imperatives for patients and members of the public to engage as partners in identifying health research priorities. The use of participatory methods to engage stakeholders in health care in research prioritization is not commonly reported.

Objective

This article analyses the use of World Cafés as a participatory method for research prioritization with marginalized communities in Ireland and the USA.

Methods

The principles of purposeful and snowball sampling were followed in both settings and a diverse range of community and health care stakeholders participated (n = 63 Ireland and n = 55 USA). The principles for a classic World Café were employed but there were novel features in each setting as well. Stewart et al.'s (Patients' and clinicians' research priorities. Health Expect 2011; 14: 439-48, conceptual framework for patient engagement was adapted and used to comparatively analyse the strengths and weaknesses of the World Cafés, focusing on agenda setting, engagement with research processes, interactional features and outputs.

Results

Design principles for World Cafés were found to align with high-quality patient engagement for research prioritization in both settings. They served to facilitate meaningful collaboration among stakeholder groups in research prioritization (research agenda setting) and explored research priorities (engagement with research). The café ambience, emphasis on hospitality and self-facilitation created an environment for dialogues within and across participating groups (interactional features). There was a commitment to follow-up actions with reference to possible subsequent research (outputs).

Conclusions

The World Café is a valuable, participatory, flexible method that can be used with community and health care stakeholders for research prioritization with marginalized communities.

Acculturation and post-migration psychological symptoms among Iraqi refugees: A path analysis

Refugees frequently experience symptoms of posttraumatic stress and depression, which impede their acculturation in the new host country where they are resettling. There are few longitudinal studies investigating predictors of mental health and acculturation during the early postmigration period. We conducted a longitudinal study of 298 Iraqi refugees, assessing them upon arrival to the U.S. and 1 year after migration. Premigration trauma was associated with increased PTSD and depressive symptoms at baseline, and with decreased acculturation 1 year later. Resilience was associated with depressive symptoms at 1-year follow-up, but not with other resettlement outcomes (PTSD symptoms, English-language skills, or acculturation). PTSD and depressive symptoms at baseline predicted the same symptoms at 1-year follow-up, but not any other resettlement outcomes. The number of chronic diseases at baseline predicted worse PTSD and depressive symptoms, acculturation, and English language skills at 1-year follow up. Postmigratory exposure to daily stressors and less social support predicted worse 1-year outcomes. Results suggest that interventions that aim to improve mental health and promote acculturation among refugees should assess their history of trauma, chronic disorders, and psychological symptoms soon after migration, and promptly provide opportunities for social support.

Pilot Study of Exercise Therapy on Painful Diabetic Peripheral Neuropathy

OBJECTIVE

Painful diabetic peripheral neuropathy (DPN) is a common complication of diabetes. While the beneficial effect of exercise on diabetes is well established, its effect specifically on painful DPN has not been thoroughly explored. The objective of this pilot study was to examine the effect of aerobic exercise on pain in people with DPN.

METHODS

Fourteen sedentary individuals (mean age 57 ± 5.11 years) with painful DPN were enrolled in a 16-week, supervised aerobic exercise program. The Brief Pain Inventory-Diabetic Peripheral Neuropathy was used to assess pain intensity (worst, least, average, now) and pain interference with daily life (activity, mood, walk, normal work, relationship, sleep, enjoyment of life) pre intervention and postintervention. Body mass index (BMI), maximum oxygen uptake (VO2max ), hemoglobin A1c (HbA1c), and blood pressure were also measured preintervention and postintervention as secondary outcomes of interest.

RESULTS

Significant reductions in pain interference were observed with walking (4.93 ± 3.03 pre to 3.29 ± 2.89 post, P = 0.016), normal work (5.39 ± 3.32 pre to 3.79 ± 3.04 post, P = 0.032), relationship with others (3.96 ± 3.53 pre to 1.29 ± 1.27 post, P = 0.006), sleep (5.11 ± 3.04 pre to 3.5 ± 3.03 post, P = 0.02), and the overall pain interference (4.65 ± 2.70 pre to 2.97 ± 2.22 post, P = 0.013) following the intervention; however, there was no change in pain intensity. VO2max increased significantly postintervention (16.02 ± 3.84 ml/kg/min pre to 17.18 ± 4.19 ml/kg/min, P = 0.028), while BMI, HbA1c, and blood pressure remained unchanged.

CONCLUSION

These preliminary results suggest that perceived pain interference may be reduced following an aerobic exercise intervention among people with painful DPN, without a change in pain intensity. Further validation by a RCT is needed.

Communication during patient-provider encounters regarding diabetes self-management

BACKGROUND AND OBJECTIVES

Diabetes is a common chronic illness with potentially severe complications. The risk of complications is reduced through controlling blood sugar, lipids, and blood pressure. While medical intervention is important, substantial self-management on the part of patients is required to achieve good control. Patients often find self-management difficult, particularly diet and exercise modification. Clinicians face barriers as well, including lack of time, poor reimbursement, and difficulty changing their clinical practice patterns. We hypothesized that a strong focus on readily measured disease indicators competes with patients' agendas relating to symptoms and their day-to-day social context.

METHODS

We recorded clinical encounters to study communication about self-management in context. Recordings were transcribed verbatim and analyzed, primarily using a grounded theory approach.

RESULTS

We found that clinicians often focused their communication on quantitative measures such as blood pressure and glycosylated hemoglobin but that patients found it difficult to relate these measures to how they were feeling physically. Patients' social contexts influenced their self-management activities, in particular heavy caregiving responsibilities and work schedules.

CONCLUSIONS

Supporting self-management of patients with diabetes requires providers to link clinical measurements to patients' symptoms and likely outcomes. It is difficult for providers to know what support or assistance their patients need without knowledge of patients' social contexts.

Patient-provider communication about diabetes self-care activities

BACKGROUND AND OBJECTIVES

Controlling diabetes requires sustained self-management on the part of patients. Health care providers can support patients' self-care efforts through communication and problem solving. We conducted this study to determine the frequency with which self-care activities were discussed during office visits for follow-up care of diabetes and how much time was spent on these discussions.

METHODS

Audio recordings of 28 patient encounters in five primary care clinics were analyzed. We determined the frequency of self-care discussions and the amount of time devoted to these discussions.

RESULTS

Self-care was discussed in all 28 encounters. Median encounter times for each clinic ranged from 19.8 to 37.6 minutes, with self-care discussions taking from 0.1 to 17.2 minutes. Median discussion time devoted to all self-care activities was 5.2 minutes, representing 23.5% of a visit of median length. Blood sugar testing was discussed longer than the other activities. The least time was devoted to eye and foot examinations. Discussions were usually initiated by providers and did not differ in length according to who initiated the discussion.

CONCLUSIONS

Patients with diabetes regularly discussed self-care activities during follow-up visits at family medicine clinics. Providers varied in their capacity to incorporate self-care planning into routine medical care for patients with diabetes. Interventions are needed that help improve goal-setting and documentation. Documentation of self-care discussions will be important for meeting Meaningful Use criteria.

Bike, walk, and wheel: a way of life in Columbia, Missouri, revisited

BACKGROUND

In 2003, Columbia MO was the recipient of a Robert Wood Johnson Foundation (RWJF) Active Living by Design (ALbD) grant to foster active living in the community through behavioral (social marketing, education) and environmental change (improved street design standards, sidewalks around schools, activity-friendly infrastructure) strategies.

PURPOSE

To examine the extent to which the ALbD intervention was associated with increased active living in children and adults community-wide.

METHODS

Seasonal pedestrian and bicyclist counts were performed quarterly in January, April, July, and October at four intersections in downtown Columbia from 2007 to 2009.

RESULTS

Pedestrian counts increased significantly during July 2009 and October 2009 compared to 2007 and 2008, whereas cyclist counts increased significantly during only July 2009 compared to 2007 and 2008.

CONCLUSIONS

The ALbD intervention in Columbia was associated with modest increases in active living in the community, and continued evaluation of these behavior patterns is warranted. The combination of multiple strategies (social marketing, local programming, and infrastructure changes) may be a critical factor in improving active living in communities.

A Walking School Bus program: impact on physical activity in elementary school children in Columbia, Missouri

BACKGROUND

The Robert Wood Johnson Foundation (RWJF) provided Columbia MO with an Active Living by Design (ALbD) grant in 2003 to promote active living in the community. A separate project was funded in 2006 through RWJF's Active Living Research program.

PURPOSE

To evaluate whether participation in a Walking School Bus (WSB) program increased or decreased active living in elementary school children residing in Columbia, in association with ALbD funding.

METHODS

Objective measures of physical activity obtained using accelerometers were collected over 7 days in children participating in a WSB program and children in a nonparticipating comparison group. Differences in the percentage of time spent in moderate- to vigorous-intensity exercise (%MVPA) were compared between groups.

RESULTS

Children in WSB programs showed no differences in %MVPA compared to children not participating in the WSB; however, when comparing the relationship of %MVPA and age, the slope of the regression line was steeper for those children not participating in the WSB.

CONCLUSIONS

The ALbD intervention in Columbia did not result in measurable changes in physical activity in children participating in the Walking School Bus program, but there was a negative association between age and physical activity, and the slope of that regression line was affected by participation in the program.

Comprehensive foot examination and risk assessment. A report of the Task Force of the Foot Care Interest Group of the American Diabetes Association, with endorsement by the American Association of Clinical Endocrinologists

The following article1 is the report of an American Diabetes Association task force that summarizes the recent literature on tests and measures to identify people at risk for foot ulceration and to recommend what should be included in the comprehensive foot exam for adult patients with diabetes. Although this information would be timely and pertinent for physical therapists at any time, its content is particularly complementary to the content of PTJ's Special Issue on Diabetes.

Metabolic effects of interventions to increase exercise in adults with type 2 diabetes

AIMS/HYPOTHESIS

The aim of this meta-analysis was to integrate the results of primary research testing the effect of diabetes self-management interventions that included recommendations to increase exercise on metabolic outcomes among adults with type 2 diabetes.

MATERIALS AND METHODS

Extensive literature searching strategies were used to identify published and unpublished intervention studies that measured glycated haemoglobin outcomes. Primary study results were coded. Fixed- and random-effects meta-analytic procedures included moderator analyses.

RESULTS

Data were synthesised across 10,455 subjects from 103 research reports. The overall mean weighted effect size for two-group comparisons was 0.29 (higher mean for treatment than control). This effect size is consistent with a difference in HbA1c means of 0.45% (e.g. 7.38% for treatment subjects vs 7.83% for control subjects). For single-group studies, the overall mean weighted effect size was 0.32-0.34. Control group subjects experienced no improvement in metabolic control during participation in the studies. Interventions that targeted multiple health behaviours resulted in smaller effect size estimates (0.22) than interventions that focused only on exercise behaviours (0.45). Funded studies reported greater improvements in metabolic controls. Studies with a greater proportion of female subjects reported lower effect sizes. Baseline HbA1c and BMI were unrelated to metabolic outcomes.

CONCLUSIONS/INTERPRETATION

These findings suggest that self-management interventions that include exercise recommendations improve metabolic control, despite considerable heterogeneity in the magnitude of the intervention effect. Interventions that emphasise exercise may be especially effective in improving metabolic control. Primary research testing interventions in randomised trials to confirm causal relationships would be constructive.

Motivational brochures increase the number of medicare-eligible persons with diabetes making therapeutic footwear claims

OBJECTIVE

This study tests the hypothesis that Medicare beneficiaries at high risk of foot complications who are mailed a motivational brochure describing the Medicare diabetes-related therapeutic footwear benefit will increase their therapeutic footwear-related Medicare claims.

RESEARCH DESIGN AND METHODS

In this quasi-experimental study, a motivational brochure was mailed in the summer of 1997 to 5,872 Medicare beneficiaries in Washington, Alaska, and Idaho who were identified as being at high risk for foot-related claims on the basis of their prior Medicare claims history. Beneficiaries were identified through footwear claims made in these states-and also in three comparison states (Oregon, Montana, and Wyoming)-during the 18 months before and after the mailing. Linear regression was used to compare the number of persons making claims in the intervention states with the comparison states before, at the time of, and after the mailing.

RESULTS

Before the intervention, the number of persons making claims was increasing in the non-intervention states and decreasing in the intervention states. During the first month after the intervention mailing, the number of persons making claims remained nearly the same in non-intervention states, but increased 13 persons per month in intervention states (95% CI 3.5-11 persons/month). After the intervention, the number of persons making claims continued to increase similarly in both intervention and non-intervention states.

CONCLUSIONS

Mailed motivational brochures were associated with an increase in the number of persons making therapeutic footwear claims. Randomized trials should confirm these findings.

Interferon-gamma responses to candidate leprosy skin-test reagents detect exposure to leprosy in an endemic population

New tools for the detection of leprosy exposure in a community will be necessary for the eradication of leprosy. Candidate leprosy skin-test antigens derived from the fractionation of the leprosy bacillus into cytoplasmic and cell-wall proteins free of immuno-inhibitory mycobacterial lipoglycans and carbohydrates were used in an overnight blood test to determine whether exposure to leprosy can be detected by the production of the cytokine interferon gamma (IFN-gamma). Strong IFN-gamma responses were detected in leprosy contacts to both skin-test antigens compared with control subjects from the same endemic communities. There was little response in patients with tuberculosis. Responses were greatest in contacts with recent leprosy exposure. The implications of these findings for the application of these reagents in a field trial as skin tests to detect exposure to leprosy are discussed in light of the strong association between overnight IFN-gamma to PPD and the tuberculin skin-test responses previously reported.

Risk factors for erythema nodosum leprosum

A retrospective study of new borderline lepromatous and lepromatous patients reporting for multidrug therapy (MDT) for leprosy at the Anandaban Leprosy Hospital, Kathmandu, Nepal, over an 8-year period was conducted to determine the prevalence of erythema nodosum leprosum (ENL), the time and frequency of reactions, and clinical and laboratory parameters associated with ENL. An overall prevalence of ENL in this cohort of 19% was found. One third of these reactions occurred in patients before MDT was given, one third in the first 6 months and one third after 6 months of treatment. Nearly 1 in 10 of the ENL reactions occurred in patients who had completed 2 years of MDT; 45% of patients with ENL had more than one episode. Data collected at the patients' first presentation was used to identify four major risk factors. Patients with lepromatous disease, skin infiltration or a bacterial index (BI) of > 4+ were at significantly increased risk. Patients older than 40 were at significantly decreased risk of ENL. There was a linear relationship in the risk of ENL with an increasing BI and an inverse relationship to increasing age. These observations should enable clinicians to recognize patients at first presentation who will be likely to develop ENL.
