Connecting Vietnamese-Speaking Immigrants who Smoke to the Asian Smokers Quitline: A Feasibility Pilot of Proactive Outreach Interventions.

INTRODUCTION: Cigarette smoking is highly prevalent among Asian American immigrant subgroups. Previously, Asian-language telephone Quitline services were only available in California. In 2012, the Centers for Disease Control and Prevention (CDC) funded the national Asian Smokers' Quitline (ASQ) to expand Asian-language Quitline services nationally. However, there are relatively few calls to the ASQ from outside California. AIMS AND METHODS: This pilot study assessed the feasibility of two proactive outreach interventions to connect Vietnamese-speaking participants who smoke to the ASQ. Both interventions, (1) proactive telephone outreach with a counselor trained in motivational interviewing (PRO-MI) and (2) proactive telephone outreach with interactive voice response (PRO-IVR), were adapted to be culturally and linguistically appropriate for Vietnamese-speaking participants. Participants were randomly assigned 2:1 to PRO-IVR versus PRO-MI. Assessments were conducted at baseline and 3 months post-enrollment. Feasibility indicators were the recruitment rate and initiation of ASQ treatment. RESULTS: Using the HealthPartners electronic health record, a large health system in Minnesota, we identified approximately 343 potentially eligible Vietnamese participants who were mailed invitation letters and baseline surveys with telephone follow-up. We enrolled 86 eligible participants (25% recruitment rate). In the PRO-IVR group 7/58 participants were directly transferred to the ASQ (12% initiation rate) and in the PRO-MI group 8/28 participants were warm transferred to the ASQ (29% initiation rate). CONCLUSIONS: This pilot study demonstrates the feasibility of our recruitment methods and of implementing proactive outreach interventions to promote the initiation of smoking cessation treatment with the ASQ. IMPLICATIONS: This pilot study contributes novel data on the uptake of Asian Smokers' Quitline (ASQ) services among Vietnamese-speaking people who smoke (PWS) with two proactive outreach interventions: (1) proactive telephone outreach with a counselor trained in motivational interviewing (PRO-MI) and (2) proactive telephone outreach with interactive voice response (PRO-IVR). We found that it is feasible to implement these proactive outreach interventions to promote the initiation of ASQ cessation treatment among Vietnamese-language speaking PWS. Future large trials are needed to rigorously compare PRO-MI and PRO-IVR and conduct budget impact analyses to understand the most efficient strategies for incorporation into health system settings.

An Analysis of the Role of Mental Health in a Randomized Trial of a Walking Intervention for Black Veterans With Chronic Pain.

Black patients and those with co-occurring mental health disorders are disproportionately affected by chronic pain, but few interventions target these populations. This is a secondary analysis of a randomized trial of a walking-focused proactive counseling intervention for Black Veterans with chronic musculoskeletal pain (ACTION). The primary aim was to examine intervention effectiveness among Veterans with an electronic health record-documented mental health diagnosis [depressive disorder, anxiety disorder, substance use disorder, post-traumatic stress disorder or serious mental illness (n = 205)] and those without a diagnosis (n = 175). About 380 Black Veterans receiving care at the Atlanta VA Health Care System were enrolled from 2016 to 2019 and randomized to the intervention or usual care (UC) (1:1). The intervention featured 6 telephone coaching sessions over 8-14 weeks to encourage walking. Participants with a mental health disorder were more likely to complete all counseling sessions (56% vs 38%) and reported improvements in global perceptions of pain and pain intensity/interference (secondary outcomes) at 3-months vs UC. Among participants without a mental health disorder, the intervention was associated with an improvement in pain-related disability at 6-months (primary outcome). Black chronic pain patients with co-occurring mental health disorders may require more intensive treatment to affect improvement in pain-related disability. PERSPECTIVE: This study examines the effectiveness of a walking intervention for chronic pain among Black Veterans with a mental health disorder. These patients were more engaged with the intervention than those without a mental health disorder. However, they did not experience reductions in pain-related disability, suggesting more intensive treatment is needed.

Taking ACTION to Reduce Pain: a Randomized Clinical Trial of a Walking-Focused, Proactive Coaching Intervention for Black Patients with Chronic Musculoskeletal Pain.

BACKGROUND: Black patients in the USA are disproportionately affected by chronic pain, yet there are few interventions that address these disparities. OBJECTIVE: To determine whether a walking-focused, proactive coaching intervention aimed at addressing contributors to racial disparities in pain would improve chronic pain outcomes among Black patients compared to usual care. DESIGN: Randomized controlled trial with masked outcome assessment ( Clinicaltrials.gov : NCT01983228). PARTICIPANTS: Three hundred eighty Black patients at the Atlanta VA Health Care System with moderate to severe chronic back, hip, or knee pain. INTERVENTION: Six telephone coaching sessions over 8-14 weeks, proactively delivered, using action planning and motivational interviewing to increase walking, or usual care. MAIN MEASURES: Primary outcome was a 30% improvement in pain-related physical functioning (Roland Morris Disability Questionnaire [RMDQ]) over 6 months among Black patients, using intention-to-treat. Secondary outcomes were improvements in pain intensity and interference, depression, anxiety, global impression of change in pain, and average daily steps. KEY RESULTS: The intervention did not produce statistically significant effects on the primary outcome (at 6 months, 32.4% of intervention participants had 30% improvement on the RMDQ vs. 24.7% of patients in usual care; aOR=1.61, 95% CI, 0.94 to 2.77), nor on other secondary outcomes assessed at 6 months, with the exception that intervention participants reported more favorable changes in pain relative to usual care (mean difference=-0.54, 95% CI, -0.85 to -0.23). Intervention participants also experienced a significant reduction in pain intensity and pain interference over 3 months (mean difference=-0.55, 95% CI, -0.88 to -0.22). CONCLUSIONS: A novel intervention to improve chronic pain among Black patients did not produce statistically significant improvements on the primary outcome relative to usual care. More intensive efforts are likely required among this population, many of whom were economically disadvantaged and had mental health comorbidities and physical limitations.

Healthcare Providers' Responses to Narrative Communication About Racial Healthcare Disparities.

We used qualitative methods (semi-structured interviews with healthcare providers) to explore: 1) the role of narratives as a vehicle for raising awareness and engaging providers about the issue of healthcare disparities and 2) the extent to which different ways of framing issues of race within narratives might lead to message acceptance for providers' whose preexisting beliefs about causal attributions might predispose them to resist communication about racial healthcare disparities. Individual interviews were conducted with 53 providers who had completed a prior survey assessing beliefs about disparities. Participants were stratified by the degree to which they believed providers contributed to healthcare inequality: low provider attribution (LPA) versus high provider attribution (HPA). Each participant read and discussed two differently framed narratives about race in healthcare. All participants accepted the "Provider Success" narratives, in which interpersonal barriers involving a patient of color were successfully resolved by the provider narrator, through patient-centered communication. By contrast, "Persistent Racism" narratives, in which problems faced by the patient of color were more explicitly linked to racism and remained unresolved, were very polarizing, eliciting acceptance from HPA participants and resistance from LPA participants. This study provides a foundation for and raises questions about how to develop effective narrative communication strategies to engage providers in efforts to reduce healthcare disparities.

Communicating with providers about racial healthcare disparities: The role of providers' prior beliefs on their receptivity to different narrative frames.

OBJECTIVE: Evaluate narratives aimed at motivating providers with different pre-existing beliefs to address racial healthcare disparities. METHODS: Survey experiment with 280 providers. Providers were classified as high or low in attributing disparities to providers (HPA versus LPA) and were randomly assigned to a non-narrative control or 1 of 2 narratives: "Provider Success" (provider successfully resolved problem involving Black patient) and "Provider Bias" (Black patient experienced racial bias, which remained unresolved). Participants' reactions to narratives (including identification with narrative) and likelihood of participating in disparities-reduction activities were immediately assessed. Four weeks later, participation in those activities was assessed, including self-reported participation in a disparities-reduction training course (primary outcome). RESULTS: Participation in training was higher among providers randomized to the Provider Success narrative compared to Provider Bias or Control. LPA participants had higher identification with Provider Success than Provider Bias narratives, whereas among HPA participants, differences in identification between the narratives were not significant. CONCLUSIONS: Provider Success narratives led to greater participation in training than Provider Bias narratives, although providers' pre-existing beliefs influenced the narrative they identified with. PRACTICE IMPLICATIONS: Provider Success narratives may be more effective at motivating providers to address disparities than Provider Bias narratives, though more research is needed.

Sex-difference in bone architecture and bone fragility in Vietnamese.

This study sought to define the sex-difference in trabecular and cortical bone parameters in Vietnamese individuals. The study involved 1404 women and 864 men aged between 20 and 86 years who were recruited from Ho Chi Minh City, Vietnam. Trabecular and cortical volumetric BMD were measured at the proximal tibia and proximal radius at 4%, 38%, and 66% points, using a peripheral quantitative computed tomography XCT2000 (Stratec, Germany). Polar strength strain index was estimated from cortical bone parameters. Changes in bone parameters were assessed by the multiple linear regression model. Among individuals aged 20-39 years, women had significantly lower peak trabecular BMD at both the radius (40%) and tibia (16%) than men, but the age-related reduction in trabecular BMD were similar between two sexes. For cortical BMD, peak values in women and men were comparable, but the age-related diminution was greater in women than men. At any age, polar strength strain index in women was lower than men, and the difference was mainly attributable to cortical bone area and total bone mass. We conclude that in the elderly, sex-related difference in trabecular BMD is originated during growth, but sex-related difference in cortical BMD is determined by differential age-related bone loss.

What Causes Racial Health Care Disparities? A Mixed-Methods Study Reveals Variability in How Health Care Providers Perceive Causal Attributions.

Progress to address health care equity requires health care providers' commitment, but their engagement may depend on their perceptions of the factors contributing to inequity. To understand providers' perceptions of causes of racial health care disparities, a short survey was delivered to health care providers who work at 3 Veterans Health Administration sites, followed by qualitative interviews (N = 53). Survey data indicated that providers attributed the causes of disparities to social and economic conditions more than to patients' or providers' behaviors. Qualitative analysis revealed differences in the meaning that participants ascribed to these causal factors. Participants who believed providers contribute to disparities discussed race and racism more readily, identified the mechanisms through which disparities emerge, and contextualized patient-level factors more than those who believed providers contributed less to disparities. Differences in provider understanding of the underlying causal factors suggest a multidimensional approach to engage providers in health equity efforts.

Taking ACTION to reduce pain: ACTION study rationale, design and protocol of a randomized trial of a proactive telephone-based coaching intervention for chronic musculoskeletal pain among African Americans.

BACKGROUND: Rates of chronic pain are rising sharply in the United States and worldwide. Presently, there is evidence of racial disparities in pain treatment and treatment outcomes in the United States but few interventions designed to address these disparities. There is growing consensus that chronic musculoskeletal pain is best addressed by a biopsychosocial approach that acknowledges the role of psychological and environmental factors, some of which differ by race. METHODS/DESIGN: The primary aim of this randomized controlled trial is to test the effectiveness of a non-pharmacological, self-regulatory intervention, administered proactively by telephone, at improving pain outcomes and increasing walking among African American patients with hip, back and knee pain. Participants assigned to the intervention will receive a telephone counselor delivered pedometer-mediated walking intervention that incorporates action planning and motivational interviewing. The intervention will consist of 6 telephone counseling sessions over an 8-10 week period. Participants randomly assigned to Usual Care will receive an informational brochure and a pedometer. The primary outcome is chronic pain-related physical functioning, assessed at 6 months, by the revised Roland and Morris Disability Questionnaire, a measure recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT). We will also examine whether the intervention improves other IMMPACT-recommended domains (pain intensity, emotional functioning, and ratings of overall improvement). Secondary objectives include examining whether the intervention reduces health care service utilization and use of opioid analgesics and whether key contributors to racial/ethnic disparities targeted by the intervention mediate improvement in chronic pain outcomes Measures will be assessed by mail and phone surveys at baseline, three months, and six months. Data analysis of primary aims will follow intent-to-treat methodology. DISCUSSION: We will tailor our intervention to address key contributors to racial pain disparities and examine the effects of the intervention on important pain treatment outcomes for African Americans with chronic musculoskeletal pain.

In vitro immunomodulation for enhancing T cell-based diagnosis of Mycobacterium tuberculosis infection.

Interferon-gamma release assays have limited sensitivity for detecting latent tuberculosis infection. In this study, we determine if the addition of immunomodulators to the QuantiFERON-TB Gold In-Tube (QFT-GIT) increased test sensitivity without compromising specificity. We prospectively compared QFT-GIT results with and without incubation with 2 immunomodulators (lipopolysaccharide [LPS] and polyinosine-polycytidylic acid [PolyIC]) in 2 cohorts-113 culture-confirmed tuberculosis (TB) subjects in Hanoi, Vietnam, and 226 documented QFT-GIT-negative, low TB risk health care workers undergoing annual TB screening at a US academic institution. Sensitivity of the tests in TB subjects was 84.1% with the standard QFT-GIT and 85.8% and 74.3% after incubation with LPS and PolyIC, respectively. Specificity in low TB risk health care workers was 100% with the standard QFT-GIT by design and 86.7% with LPS and 63.3% with PolyIC. In conclusion, use of the 2 immunomodulators did not improve sensitivity of the QFT-GIT in TB patients and reduced specificity in low-risk health care workers.

Training primary care clinicians in motivational interviewing: a comparison of two models.

OBJECTIVES: To evaluate implementing two training models for motivational interviewing (MI) to address tobacco use with primary care clinicians. METHODS: Clinicians were randomized to moderate or high intensity. Both training modalities included a single ½ day workshop facilitated by MI expert trainers. The high intensity (HI) training provided six booster sessions including telephone interactions with simulated patients and peer coaching by MI champions over 3 months. To assess performance of clinicians to deliver MI, an objective structured clinical evaluation (OSCE) was conducted before and 12 weeks after the workshop training. RESULTS: Thirty-four clinicians were enrolled; 18 were randomly assigned to HI. Compared to the moderate intensity group, the HI group scored significantly higher during the OSCE for three of six global Motivational Interviewing Treatment Integrity scale scores. There was also significant improvement for three of the four measures of MI counseling knowledge, skills and confidence. CONCLUSIONS: Using champions and telephone interactions with simulated patients as enhancement strategies for MI training programs is feasible in the primary care setting and results in greater gains in MI proficiency. PRACTICE IMPLICATIONS: Results confirm and expand evidence for use of booster sessions to improve the proficiency of MI training programs for primary care clinicians.

A brief self-affirmation study to improve the experience of minority patients.

BACKGROUND: There is evidence that Black patients may experience stereotype threat--apprehension about being negatively stereotyped--in healthcare settings, which might adversely affect their behavior in clinical encounters. Recent studies conducted outside of healthcare have shown that a brief self-affirmation intervention, in which individuals are asked to focus on and affirm their valued characteristics and sources of personal pride, can reduce the negative effects of stereotype threat on academic performance and on interpersonal communication. METHODS: This randomised controlled trial examined whether a self-affirmation (SA) intervention would decrease the negative effects of stereotype threat (negative mood, lower state self-esteem, greater perceptions of racial discrimination) and increase communication self-efficacy among Black primary care patients. Self-affirmation was induced by having patients complete a 32-item values affirmation questionnaire. RESULTS: Patients in the SA condition had lower levels of performance self-esteem and social self-esteem than patients in the control. There were no differences between the SA and the control groups on negative mood, communication self-efficacy, and perceptions of discrimination. CONCLUSIONS: Our SA intervention lowered state self-esteem among Black patients. Future research is needed to determine the type of SA task that is most effective for this population.
