ABSTRACT

PURPOSE: Healthy cancer survivorship involves patients' active engagement with preventative health behaviors and follow-up care. While clinicians and patients have typically held dual responsibility for activating these behaviors, transitioning some clinician effort to technology and health coaches may enhance guideline implementation. This paper reports on the acceptability of the Shared Healthcare Actions & Reflections Electronic systems in survivorship (SHARE-S) program, an entirely virtual multicomponent intervention incorporating e-referrals, remotely-delivered health coaching, and automated text messages to enhance patient self-management and promote healthy survivorship. METHODS: SHARE-S was evaluated in single group hybrid implementation-effectiveness pilot study. Patients were e-referred from the clinical team to health coaches for three health self-management coaching calls and received text messages to enhance coaching. Semi-structured qualitative interviews were conducted with 21 patient participants, 2 referring clinicians, and 2 health coaches to determine intervention acceptability (attitudes, appropriateness, suitability, convenience, and perceived effectiveness) and to identify important elements of the program and potential mechanisms of action to guide future implementation. RESULTS: SHARE-S was described as impactful and convenient. The nondirective, patient-centered health coaching and mindfulness exercises were deemed most acceptable; text messages were less acceptable. Stakeholders suggested increased flexibility in format, frequency, timing, and length of participation, and additional tailored educational materials. Patients reported tangible health behavior changes, improved mood, and increased accountability and self-efficacy. CONCLUSIONS: SHARE-S is overall an acceptable and potentially effective intervention that may enhance survivors' self-management and well-being. Alterations to tailored content, timing, and dose should be tested to determine impact on acceptability and outcomes.

ABSTRACT

Introduction: Chronic pain is a prevalent issue among older adults in the United States that impairs quality of life. Physical activity has emerged as a cost-effective and non-pharmacological treatment for chronic pain, offering benefits such as improved physical functioning, weight loss, and enhanced mood. However, promoting physical activity in older individuals with chronic pain is challenging, given the cyclical relationship between pain and sedentary behavior. The Mobile Intervention to Reduce Pain and Improve Health (MORPH) trial was designed as an innovative, mobile health (mHealth) supported intervention to address this issue by targeting daylong movement, weight loss, and mindfulness to manage pain in older adults with chronic multisite pain. The objective of this paper is to provide the result of a qualitative analysis conducted on post-intervention interviews with MORPH participants. Methods: At the conclusion of the MORPH study, 14 participants were interviewed regarding their experience with the program. All interviews were conducted by phone before being transcribed and verified. A codebook of significant takeaways was created based on these accounts. Summaries were further synthesized into themes using the principles of thematic analysis. Results: Three key themes of the MORPH intervention emerged from the qualitative interviews: MORPH technology (smart scales, Fitbit, MORPH Companion App) facilitated program adherence and accountability; MORPH intervention components (food tracking and mindfulness activities) facilitated program adherence and awareness, respectively; and, group meetings provided motivational support and accountability. Mobile health technologies, including a dedicated MORPH app, facilitated self-monitoring strategies, helped to break the cycle of old habits, and provided participants with immediate feedback on successes; however, technical issues required timely support to maintain engagement. Food tracking contributed to adherence and accountability for weight loss. Mindfulness activities increased participants' awareness of anxiety provoking thoughts and pain triggers. Finally, social support via group meetings and connection, played a crucial role in behavior change, but participants noted consistency in the delivery medium was essential to fostering genuine connections. Conclusion: Overall, the study results highlight the key considerations related to program technology, intervention components, and the value of social support that can help to guide the development of future interventions similar to MORPH.

ABSTRACT

Objectives: Participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) has numerous benefits, yet many eligible children remain unenrolled. This qualitative study sought to explore perceptions of a novel electronic health record (EHR) intervention to facilitate referrals to WIC and improve communication/coordination between WIC staff and healthcare professionals. Methods: WIC staff in three counties were provided EHR access and recruited to participate. An automated, EHR-embedded WIC participation screening and referral tool was implemented within 8 healthcare clinics; healthcare professionals within these clinics were eligible to participate. The interview guide was developed using the Consolidated Framework for Implementation Research to elicit perceptions of this novel EHR-based intervention. Semi-structured interviews were conducted via telephone. Interviews were recorded, transcribed, coded, and analyzed using thematic analysis. Results: Twenty semi-structured interviews were conducted with eight WIC staff, seven pediatricians, four medical assistants, and one registered nurse. Most participants self-identified as female (95%) and White (55%). We identified four primary themes: (1) healthcare professionals had a positive view of WIC but communication and coordination between WIC and healthcare professionals was limited prior to WIC having EHR access; (2) healthcare professionals favored WIC screening using the EHR but workflow challenges existed; (3) EHR connections between WIC and the healthcare system can streamline referrals to and enrollment in WIC; and (4) WIC staff and healthcare professionals recommended that WIC have EHR access. Conclusions: A novel EHR-based intervention has potential to facilitate healthcare referrals to WIC and improve communication/coordination between WIC and healthcare systems.

ABSTRACT

PURPOSE: Improved management of pain and co-morbid symptoms (sleep disturbances, psychological distress) among women undergoing surgery for suspected gynecologic malignancies may reach a population vulnerable to chronic pain. PARTICIPANTS: Women undergoing surgery for a suspected gynecologic malignancy. METHOD: We conducted a pilot randomized controlled trial of eHealth Mindful Movement and Breathing (eMMB) compared to an empathic attention control (AC). Semi-structured interviews were conducted by telephone (n = 23), recorded, transcribed, coded, and analyzed using thematic analysis. FINDINGS: Participants reported overall high acceptability such that all would recommend the study to others. Positive impacts of practicing eMMB included that it relieved tension, facilitated falling asleep, and decreased pain. Participants also reported high adherence to self-directed eMMB and AC writing practices and described facilitators and barriers to practicing. CONCLUSIONS: This qualitative feedback will inform future research to assess the efficacy of eMMB for reducing pain and use of remotely-delivered interventions more broadly. CLINICAL TRIAL REGISTRATION NUMBER: NCT03681405.

ABSTRACT

The US Food and Drug Administration is considering banning menthol cigarettes, which could result in some people who smoke menthol cigarettes switching to other tobacco products (OTPs). This qualitative study explored reactions to using OTPs instead of menthol cigarettes. People who smoke menthol cigarettes (N=40) completed a behavioral economic assessment of the effects of menthol cigarette price increases on OTP purchasing. At the highest price, most participants could not afford menthol cigarettes. Instead, they could purchase non-menthol cigarettes, little cigars/cigarillos (LCCs), e-cigarettes, smokeless tobacco, or medicinal nicotine, or they could abstain from tobacco use. Participants used the OTPs they purchased for three days. During follow-up sessions, participants (n=35) completed semi-structured interviews discussing their purchasing-decisions and experiences using OTPs instead of menthol cigarettes. Interviews were analyzed using reflexive thematic analysis methods. Factors influencing purchasing decisions included flavor, price, prior use of OTPs, interest in trying new OTPs, and perceived ability to satisfy nicotine cravings. Participants described positive experiences using e-cigarettes including the "refreshing" menthol flavor, ability to use in places where cigarettes are prohibited, and convenience of use relative to smoking. Among those using non-menthol cigarettes, many reported they were acceptable but less satisfying products compared to menthol cigarettes while others reported negative reactions to them such as tasting like "cardboard". Reactions to smoking LCCs were mostly unfavorable but participants said it gave them "something to light". Multiple considerations may affect switching to OTPs in light of pending menthol cigarette regulation including the availability of menthol-flavored alternatives and (dis)satisfaction with OTPs.

ABSTRACT

Screening for cognitive impairment following ICU discharge is recommended but not part of routine care. We sought to understand older adults' perspectives on screening for cognitive impairment following an ICU admission to inform the design and delivery of a cognitive screening intervention. DESIGN: Qualitative study using semi-structured interviews. SUBJECTS: Adults 60 years and older within 3 months of discharge from an ICU in an academic health system. INTERVENTIONS: Interviews were conducted via telephone, audio recorded and transcribed verbatim. All transcripts were coded in duplicate. Discrepancies were resolved by consensus. Codes were organized into themes and subthemes inductively. MEASUREMENTS AND MAIN RESULTS: We completed 22 interviews. The mean age of participants was 71 ± 6 years, 14 (63.6%) were men, 16 (72.7%) were White, and 6 (27.3%) were Black. Thematic analysis was organized around four themes: 1) receptivity to screening, 2) communication preferences, 3) information needs, and 4) provider involvement. Most participants were receptive to cognitive screening; this was influenced by trust in their providers and prior experience with cognitive screening and impairment. Participants preferred simple, direct, compassionate communication. They wanted to understand the screening procedure, the rationale for screening, and expectations for recovery. Participants desired input from their primary care provider to have their cognitive screening results placed in the context of their overall health, because they had a trusted relationship, and for convenience. CONCLUSIONS: Participants demonstrated limited understanding of and exposure to cognitive screening but see it as potentially beneficial following an ICU stay. Providers should use simple, straightforward language and place emphasis on expectations. Resources may be needed to assist primary care providers with capacity to provide cognitive screening and interpret results for ICU survivors. Implementation strategies can include educational materials for clinicians and patients on rationale for screening and recovery expectations.

ABSTRACT

The Biden Administration is considering a low nicotine product standard for cigarettes. This qualitative study examined reactions to a nicotine reduction policy among adolescents and young adults (AYA) who smoke cigarettes. After completing a lab study involving masked exposure either to low nicotine or normal nicotine research cigarettes and unmasked exposure to e-cigarettes varying in nicotine concentration and flavor, we conducted follow-up semi-structured interviews (N = 25) to explore participants' knowledge, attitudes, and perceptions of a low nicotine product standard and their anticipated tobacco use behavior after policy implementation. Interviews were audio-recorded, transcribed verbatim, double-coded, and analyzed using reflexive thematic analysis. Nearly half of participants supported the policy because they thought it would prevent young people from starting smoking and/or would help people quit. Reasons some participants opposed the policy included beliefs that adults should have the choice to smoke or that a nicotine reduction policy is counterintuitive because the government benefits from cigarette sales. Others believed the policy would be ineffective because youth could circumvent the policy (e.g., illicit market) or would increase their smoking to maintain the same nicotine level. Almost half of participants said they would quit smoking while the other half said they would continue smoking, although potentially reduce their smoking. Overall, our qualitative findings point to the need for pre-policy media campaigns targeting AYA who smoke to minimize negative reactions, dispel fears, and correct misperceptions as well as encourage quitting and provide information on accessing cessation resources.

ABSTRACT

INTRODUCTION: The ongoing COVID-19 pandemic has been associated with increased negative mood in youth, and a few reports of changes in tobacco use. We sought to increase the depth of knowledge on the effects of the pandemic on early young adult mood states, access to tobacco products and tobacco use behaviors, and knowledge of risks associated with tobacco use and COVID-19 by learning more about the lived experience of the pandemic among young adults early in their smoking trajectories. METHODS: Semi-structured qualitative interviews were conducted with 25 young adults ages 18-20 (M = 19) who smoked cigarettes daily or nearly every day and had used electronic cigarettes (ECs) on ≥ 2 occasions in their lifetime. RESULTS: Our results uncovered several themes: 1) The majority of teens experienced mental health disturbances as a result of the pandemic, which manifested as depression, anxiety, and/or acute loneliness due to social isolation; 2) tobacco purchasing behaviors sometimes changed, with both greater and less access reported among participants; 3) changes in tobacco use were also reported, with some reporting increases in use, others reporting decreases, and a few reporting quitting; and 4) while some youth reported that tobacco use could increase their risk related to COVID-19, the majority reported confusion and uncertainty about how tobacco use impacted their risk. CONCLUSIONS: The themes identified specific factors that may account for the heterogeneity of impacts of the pandemic on tobacco use, and highlight the value of qualitative work for centering the lived experience of youth for understanding larger trends in substance use.

ABSTRACT

Background: Patient portals can be an innovative and efficient way to engage patients in advance care planning (ACP). However, comprehension and judgment in older adults with cognitive impairment presents several barriers and challenges to engaging in new technology. Our objective was to develop an ACP portal-based tool (ACPVoice) for community-dwelling persons living with cognitive impairment (PLCI) by engaging end-users in the design process. Methods: Two rounds of cognitive interviews were conducted to identify and resolve cognitive issues related to comprehension, judgment, response, and to assess content validity. Purposive sampling was used with the goal of enrolling 15 different participants (five with mild cognitive impairment and five dyads (those with mild dementia and their care partner) in each round to assess respondents' understanding of questions related to advance care planning to be administered via the patient portal. Results: Twenty PLCI (mean age 78.4, 10 females [50%]) and ten care partners (mean age 60.9, 9 females [90%]) completed cognitive interviews between May 2021 and October 2021. The mean Mini-Mental State Examination score for PLCI was 25.6 (SD 2.6). Unclear wording and undefined vague and/or unfamiliar terms were the major issues identified. Revisions to item wording, response options, and instructions were made to improve question comprehension and response as well as navigational ease. Conclusion: Minor changes to the wording, format, and response options substantially improved respondents' ability to interpret the item content of the ACPVoice tool. Dissemination and implementation of the ACPVoice tool could help to engage community-dwelling PLCI in ACP discussions.

ABSTRACT

This qualitative study aimed to elicit the perspectives of individuals with food insecurity (FI) who were enrolled in a Fresh Food Prescription (FFRx) delivery program through a collaboration between an academic medical center and multiple community partners in the southeastern United States. Semi-structured interviews and open-ended survey responses explored the experiences of participants enrolled in a FFRx delivery program during the COVID-19 pandemic. The interviews probed the shopping habits, food security, experience, and impact of the program on nutrition, health, and well-being; the surveys explored the perceptions of and satisfaction with the program. A coding scheme was developed inductively, and a thematic analysis was conducted on raw narrative data using Atlas.ti 8.4 to sort and manage the data. The themes included that the program promoted healthy dietary habits, improved access to high-quality foods, improved well-being, enhanced financial well-being, and alleviated logistical barriers to accessing food and cooking. Participants provided suggestions for FFRx improvement. Future studies may facilitate improved clinical-community partnerships to address FI.

ABSTRACT

Community volunteering is an under-utilized, at least under-researched, strategy to supplement existing treatment for affective disorders. We present findings from a feasibility study incorporating community volunteering into clinical treatment for depression and anxiety among adolescents and young adults. This exploratory pilot study had four aims: to investigate recruitment feasibility; to describe participants' experiences with volunteering; to explore psychosocial assets by which volunteering might decrease depressive and anxiety symptoms; and to document preliminary changes in mental health outcomes before and after the volunteering intervention. Interviews and surveys were employed with participants (N = 9; ages 14-20, Mage = 16 years old; eight women and one man) newly diagnosed with: mild to moderate depression (single episode), mild to moderate anxiety, or adjustment disorder. Recruitment was feasible overall, successes and challenges are discussed. Experiences with volunteering were very positive. Qualitative findings revealed perceived positive effects of volunteering on mood and well-being such as helping with social anxiety and being a positive distraction. Qualitative findings revealed several psychosocial assets that improved related to volunteering (e.g., sense of purpose/meaning and sense of community). On average, participants reported a 19% decrease in depressive symptoms from the pre-survey (before volunteering) to the post-survey (after volunteering). Although more research is warranted, the implication of this study for practicing psychologists treating adolescents and young adults for mild to moderate depression and/or anxiety is that they may wish to consider incorporating community volunteer activities into treatment. Volunteering was a desirable activity for interested participants in treatment for affective disorders.

ABSTRACT

OBJECTIVE: The US Food and Drug Administration recently announced its intention to pursue a federal ban on menthol cigarettes. This qualitative study assessed reactions to a potential menthol cigarette ban among people who smoke menthol cigarettes. METHODS: As part of a laboratory study examining menthol flavor regulations, we conducted follow-up interviews with participants who smoke menthol cigarettes (N = 35). We explored the following topics: (1) menthol cigarette risk perceptions; (2) knowledge, attitudes, and perceptions of menthol cigarette regulations; and (3) anticipated behavior if menthol cigarettes were banned. Interviews were audio-recorded, transcribed verbatim, double-coded, and analyzed using reflexive thematic analysis. RESULTS: Many participants thought menthol cigarettes carried more health risks than non-menthol cigarettes. Some participants said regulators wanted to ban menthol cigarettes because they appeal to youth. Others thought a ban would be good for public health because fewer people, particularly youth, would smoke. Several voiced skepticism about banning only menthol cigarettes rather than all cigarettes. Most said they would use other products, including electronic cigarettes or non-menthol cigarettes, but many also thought a menthol ban could motivate them or others to quit smoking. CONCLUSIONS: Banning menthol cigarettes could lead some people who smoke menthol cigarettes to switch to potentially less harmful products, like e-cigarettes, or quit smoking, which would likely benefit public health; however, others may simply transition to non-menthol cigarettes. As regulators move forward with banning menthol cigarettes, communication campaigns explaining the public health benefits, potentially focusing on the benefits for youth, should be part of the policy implementation plan.

ABSTRACT

BACKGROUND: Evidence-based interventions are necessary for planning and investing in health information systems (HIS) and for strengthening those systems to collect, manage, sort and analyse health data to support informed decision-making. However, evidence and guidance on HIS strengthening in low- and middle-income countries have been historically lacking. OBJECTIVE: This article describes the approach, methods, lessons learned and recommendations from 5 years of applying our learning agenda to strengthen the evidence base for effective HIS interventions. METHODS: The first step was to define key questions about characteristics, stages of progression, and factors and conditions of HIS performance progress. We established a team and larger advisory group to guide the implementation of activities to build the evidence base to answer questions. We strengthened learning networks to share information. RESULTS: The process of applying the learning agenda provided a unique opportunity to learn by doing, strategically collecting information about monitoring and evaluating HIS strengthening interventions and building a body of evidence. There are now models and tools to strengthen HIS, improved indicators and measures, country HIS profiles, documentation of interventions, a searchable database of HIS assessment tools and evidence generated through syntheses and evaluation results. CONCLUSION: The systematic application of learning agenda processes and activities resulted in increased evidence, information, guidance and tools for HIS strengthening and a resource centre, making that information accessible and available globally. IMPLICATIONS: We describe the inputs, processes and lessons learned, so that others interested in designing a successful learning agenda have access to evidence of how to do so.

ABSTRACT

INTRODUCTION: Male breast cancer (MBC) is a rare disease. Rates of MBC in Northern Africa vary by region. The age-standardized incidence for MBC is higher in Morocco than in Egypt, and the Egyptian rate is similar to the U.S of approximately 1/10(5)This study aimed at investigating the clinical and molecular characteristics of MBC in Egypt and Morocco. METHODS: This case-case study included 211 cases from Egypt and 132 from Morocco. Tumor tissues were available for 47 Egyptian and 18 Moroccan patients. Medical record information was abstracted for patients' demographics, medical history, and treatment. BRCA2 protein expression status was examined in Egyptian and Moroccan tumors. Androgen receptor CAG repeat length was analyzed using the tissue samples in Egyptian MBC tumors and controls. Limited amount of tissues from Morocco did not allow for the analysis of CAG repeats. RESULTS: Egyptian MBC patients had a significantly lower age at diagnosis (Egypt: 57.5 ± 15.1, Morocco: 63.9 ± 14.4, P=0.0002) and a higher prevalence of liver cirrhosis (Egypt: 28.0%, Morocco: 0.8%, P=< 0.0001). MBC patients also had higher tumor grades [I (0.9%), II (81.0%), III (18.1%)] in Egypt vs. [I (10.7%), II (81.0%), III (8.3%)] in Morocco (P=0.0017). The clinical and molecular characteristics of the groups from the 2 countries did not significantly differ. There was no significant difference with respect to BRCA2 expression amongst countries (Egypt: 28.9% non-wild type, Morocco: 27.8% non-wild type, P=0.9297) or CAG lengths amongst BRCA2 expression types in Egyptians (Wild type: 54.6% with CAG repeat lengths of 20+, Non-wild type: 50% with CAG repeat lengths of 20+, P=0.7947). CONCLUSIONS: Differences in MBC between Egypt and Morocco are more likely due to differences in other risk factors such as consanguinity and use of xenoestrogenic pesticides.

ABSTRACT

Male breast cancer (MBC) is a rare disease in the U.S., accounting for less than 1% of all breast cancers. Rates of MBC in Africa are more variable than in the U.S., therefore, understanding the risk factors involved in a population like Egypt can clarify the nature of MBC. The polyglutamine tract (QT) is a variable region of the androgen receptor (AR), a nuclear receptor which is important in modulating androgen actions and generally inhibits growth in breast tissue. It is hypothesized that a long QT results in weaker AR activity over the lifetime, resulting in less AR mediated control over cellular division and higher risk of MBC. As a corollary, we expect to see a distribution skewed toward longer QTs in MBC patients compared to controls and overall relatively longer QT's in populations with higher rates of MBC. This study aimed to investigate for the first time the distribution of AR QT lengths among MBC patients in Egypt. Paraffin-embedded tumor tissues from 44 Egyptian MBC patients were analyzed for this polymorphism. Amplification followed by fragment length analysis revealed QT length. For the control series, blood from 43 Egyptian males without a family or personal history of breast or prostate cancers was collected and analyzed similarly. There was no significant difference between patients and controls with respect to mean QT length (P = 0.84; means were 19.5 ± 2.8 and 19.3 ± 4.2, for patients and controls, respectively). Though, short QT lengths were more prevalent among controls (14.0%), but almost absent in cases (2.3%). Although the mean lengths were not different in cases and controls, the near absence of short tracts in cases suggests a possible protective effect of very short QT lengths against MBC. In populations in which there is variable incidence of MBC by region, investigations of the distribution of AR QT lengths are warranted to further delineate its role as a risk factor in MBC.
