Healthcare disparities: patients' perspectives on barriers to joint replacement.

OBJECTIVE: Racial and ethnic disparities in arthroplasty utilization are evident, but the reasons are not known. We aimed to identify concerns that may contribute to barriers to arthroplasty from the patient's perspective. METHODS: We identified patients' concerns about arthroplasty by performing a mixed methods study. Themes identified during semi-structured interviews with Black and Hispanic patients with advanced symptomatic hip or knee arthritis were used to develop a questionnaire to quantify and prioritize their concerns. Multiple linear and logistic regression analyses were conducted to determine the association between race/ethnicity and the importance of each theme. Models were adjusted for sex, insurance, education, HOOS, JR/KOOS, JR, and discussion of joint replacement with a doctor. RESULTS: Interviews with eight participants reached saturation and provided five themes used to develop a survey answered by 738 (24%) participants; 75.5% White, 10.3% Black, 8.7% Hispanic, 3.9% Asian/Other. Responses were significantly different between groups (p < 0.05). Themes identified were "Trust in the surgeon" "Recovery", "Cost/Insurance", "Surgical outcome", and "Personal suitability/timing". Compared to Whites, Blacks were two-fold, Hispanics four-fold more likely to rate "Trust in the surgeon" as very/extremely important. Blacks were almost three times and Hispanics over six times more likely to rate "Recovery" as very/extremely important. CONCLUSION: We identified factors of importance to patients that may contribute to barriers to arthroplasty, with marked differences between Blacks, Hispanics, and Whites.

Just Say Yes? A Cluster Analytic Approach to Evaluating College Students' Understandings of Affirmative Consent.

Affirmative consent policies on college campuses establish more stringent standards for inferring consent to sex. Although these policies often permit nonverbal communication of consent, they rarely outline finer-grained distinctions about which specific behaviors can stand-in for verbal affirmation. It thus remains possible that students hold different understandings of this policy vis-à-vis the nonverbals used to convey and infer consent, which could undermine the purported utility of affirmative consent initiatives. We presently sampled 442 college undergraduates and asked them to rate whether specific behaviors often present during sexual interaction constitute affirmative indicators of consent. We hypothesized that students would separate into one of three groups depending on how restrictive (e.g., verbal communication only), inclusive (e.g., verbal and clear nonverbals) or potentially non-diagnostic (e.g., sexual arousal, passivity) their behavioral definitions were of affirmative consent. Using cluster analysis, we ultimately identified two groups adhering to a restrictive versus more inclusive operationalization. The former cluster understood affirmative consent as comprising verbal affirmation with variable endorsements of specific nonverbals, whereas the latter consistently endorsed a broader set of nonverbals along with variable ascription to behaviors that do not strongly imply consent. Students in the more inclusive group were more sexually experienced, less likely to use condoms, and viewed casual sex more favorably; as well as were likelier to have received sexual assault education from their parents before and during college, as well as from social media. These findings suggest that subgroups of college students construe affirmative consent policy differently and that these understandings may relate broadly to an individual's sexual experiences, attitudes, and/or education.

Disagreement and Uncertainty Among Experts About how to Respond to Marijuana Use in Patients on Long-term Opioids for Chronic Pain: Results of a Delphi Study.

BACKGROUND: Marijuana use is common among patients on long-term opioid therapy (LTOT) for chronic pain, but there is a lack of evidence to guide clinicians' response. OBJECTIVE: To generate expert consensus about responding to marijuana use among patients on LTOT. DESIGN: Analysis from an online Delphi study. SETTING/SUBJECTS: Clinician experts in pain and opioid management across the United States. METHODS: Participants generated management strategies in response to marijuana use without distinction between medical and nonmedical use, then rated the importance of each management strategy from 1 (not at all important) to 9 (extremely important). A priori rules for consensus were established, and disagreement was explored using cases. Thematic analysis of free-text responses examined factors that influenced participants' decision-making. RESULTS: Of 42 participants, 64% were internal medicine physicians. There was consensus that it is not important to taper opioids as an initial response to marijuana use. There was disagreement about the importance of tapering opioids if there is a pattern of repeated marijuana use without clinical suspicion for a cannabis use disorder (CUD) and consensus that tapering is of uncertain importance if there is suspicion for CUD. Three themes influenced experts' perceptions of the importance of tapering: 1) benefits and harms of marijuana for the individual patient, 2) a spectrum of belief about the overall riskiness of marijuana use, and 3) variable state laws or practice policies. CONCLUSIONS: Experts disagree and are uncertain about the importance of opioid tapering for patients with marijuana use. Experts were influenced by patient factors, provider beliefs, and marijuana policy, highlighting the need for further research.

Managing Concerning Behaviors in Patients Prescribed Opioids for Chronic Pain: A Delphi Study.

BACKGROUND: Current guideline-recommended monitoring of patients prescribed long-term opioid therapy (LTOT) for chronic pain will likely result in increased identification of behaviors of concern for misuse and addiction, but there is a dearth of empiric evidence about how these behaviors should be managed. OBJECTIVE: To establish expert consensus about treatment approaches for common and challenging concerning behaviors that arise among patients on LTOT. DESIGN: We used a Delphi approach, which allows for generation of consensus. PARTICIPANTS: Participants were clinical experts in chronic pain and opioid prescribing recruited from professional societies and other expert groups. MAIN MEASURES: The Delphi process was conducted online, and consisted of an initial brainstorming round to identify common and challenging behaviors, a second round to identify management strategies for each behavior, and two rounds to establish consensus and explore disagreement/uncertainty. KEY RESULTS: Forty-two participants completed round 1, 22 completed round 2, 30 completed round 3, and 28 completed round 4. Half of round 1 participants were female (52%), and the majority were white (83%). Most (71%) were physicians, and most participants practiced in academic primary (40%) or specialty care (19%).The most frequently cited common and challenging behaviors were missing appointments, taking opioids for symptoms other than pain, using more opioid medication than prescribed, asking for an increase in opioid dose, aggressive behavior, and alcohol and other substance use. Across behaviors, participants agreed that patient education and information gathering were important approaches. Participants also agreed that stopping opioids is not important initially, but if initial approaches do not work, tapering opioids and stopping opioids immediately may become important approaches. CONCLUSIONS: This study presents clinical expert consensus on how to manage concerning behaviors among patients on LTOT. Future research is needed to investigate how implementing these management strategies would impact patient outcomes, practice and policy.

Using Patient Perspectives to Inform the Development of a Behavioral Intervention for Chronic Pain in Patients with HIV: A Qualitative Study.

Background: Chronic pain is a common and disabling comorbidity in individuals living with HIV. Behavioral interventions are among the most effective and safe nonpharmacologic treatments for chronic pain. However, the success of a behavioral intervention is influenced by how well it is tailored to the target population's biological, psychological, and social context. Given well-documented psychosocial vulnerabilities among persons with HIV, it is critical to develop a behavioral intervention for chronic pain tailored to this population. Objective: To use qualitative methods to investigate patient preferences for the structure and delivery of a behavioral intervention for chronic pain in individuals with HIV. Methods: Interviews and focus groups were used to elicit participant preferences. A thematic analysis approach, with an initial round of open coding, was used to develop the codebook and analyze the data. Results: Qualitative data from 12 interviews and 3 focus groups with patients living with HIV and chronic pain (total N = 24) were analyzed. Emergent themes fell into four major categories: perceived value of group sessions, incorporating peer leadership, and two key elements of how the intervention should be delivered: the HIV status of group participants and views on phone-delivered intervention content. Discussion: This study provides a framework for the structure and delivery of a behavioral intervention for chronic pain in individuals with HIV based on patient preferences. We will use these results to design our intervention, and hope that our approach informs the work of investigators in other disciplines who seek to incorporate patient preferences during intervention development.

A Comparison of Health Disparities among Transgender Adults in Colorado (USA) by Race and Income.

Transgender individuals face heightened risks for discrimination, harassment, and violence that impact their psychosocial well-being and physical health. However, few studies have thoroughly examined the general physical and mental health of transgender adults or within-group health differences by race/ethnicity and income. To that end, after controlling for health insurance status, age, and engagement in exercise, this study asks: (a) are transgender people of color more likely than White transgender individuals to experience poor health outcomes?, and (b) is lower annual household income among transgender adults associated with poorer health outcomes? The current study analyzes secondary data from a survey of transgender adults (N = 417) in one state in the Western United States using multiple linear regression and logistic regression models. Transgender people of color had significantly greater odds than their White counterparts of having arthritis/rheumatoid arthritis/gout/lupus/fibromyalgia, or having asthma, but lower odds of being told by a provider that they had depression. Having a lower income was significantly associated with worse general health as well as multiple indicators of poor physical and mental health, including depression, anxiety, and suicidal ideation. We discuss implications for health care delivery for transgender people and for future research.

DNA methylation profiling reveals novel biomarkers and important roles for DNA methyltransferases in prostate cancer.

Candidate gene-based studies have identified a handful of aberrant CpG DNA methylation events in prostate cancer. However, DNA methylation profiles have not been compared on a large scale between prostate tumor and normal prostate, and the mechanisms behind these alterations are unknown. In this study, we quantitatively profiled 95 primary prostate tumors and 86 benign adjacent prostate tissue samples for their DNA methylation levels at 26,333 CpGs representing 14,104 gene promoters by using the Illumina HumanMethylation27 platform. A 2-class Significance Analysis of this data set revealed 5912 CpG sites with increased DNA methylation and 2151 CpG sites with decreased DNA methylation in tumors (FDR < 0.8%). Prediction Analysis of this data set identified 87 CpGs that are the most predictive diagnostic methylation biomarkers of prostate cancer. By integrating available clinical follow-up data, we also identified 69 prognostic DNA methylation alterations that correlate with biochemical recurrence of the tumor. To identify the mechanisms responsible for these genome-wide DNA methylation alterations, we measured the gene expression levels of several DNA methyltransferases (DNMTs) and their interacting proteins by TaqMan qPCR and observed increased expression of DNMT3A2, DNMT3B, and EZH2 in tumors. Subsequent transient transfection assays in cultured primary prostate cells revealed that DNMT3B1 and DNMT3B2 overexpression resulted in increased methylation of a substantial subset of CpG sites that showed tumor-specific increased methylation.

A Novel Approach for Mixed-Methods Research Using Large Language Models: A Report Using Patients' Perspectives on Barriers to Arthroplasty.

OBJECTIVE: Mixed-methods research is valuable in health care to gain insights into patient perceptions. However, analyzing textual data from interviews can be time-consuming and require multiple analysts for investigator triangulation. This study aims to explore a novel approach to investigator triangulation in mixed-methods research by employing a large language model (LLM) for analyzing data from patient interviews. METHODS: This study compared the thematic analysis and survey generation performed by human investigators and ChatGPT-4, which uses GPT-4 as its backbone model, using data from an existing study that explored patient perceptions of barriers to arthroplasty. The human- and ChatGPT-4-generated themes and surveys were compared and evaluated based on their representation of salient themes from a predetermined topic guide. RESULTS: ChatGPT-4 generated analogous dominant themes and a comprehensive corresponding survey as the human investigators but in significantly less time. The survey questions generated by ChatGPT-4 were less precise than those developed by human investigators. The mixed-methods flowchart proposes integrating LLMs and human investigators as a supplementary tool for the preliminary thematic analysis of qualitative data and survey generation. CONCLUSION: By utilizing a combination of LLMs and human investigators through investigator triangulation, researchers may be able to conduct more efficient mixed-methods research to better understand patient perspectives. Ethical and qualitative implications of using LLMs should be considered.

Establishment and serial passage of cell cultures derived from LuCaP xenografts.

BACKGROUND: LuCaP serially transplantable xenografts derived from primary and metastatic human prostate cancer encompass the molecular and cellular heterogeneity of the disease and are an invaluable resource for in vivo preclinical studies. A limitation of this model, however, has been the inability to establish and passage cell cultures derived from the xenografts. Here, we describe a novel spheroid culture system that supports long-term growth of LuCaP cells in vitro. METHODS: Xenografts were minced and digested with collagenase. Tissue dissociation was terminated while the majority of cells remained as clusters rather than single cells. The cell clusters were suspended in StemPro medium supplemented with R1881 and Y-27632, a Rho kinase inhibitor, and placed in ultralow attachment dishes for spheroid culture. Serial passage was achieved by partial digestion to small clusters with trypsin/EDTA in the presence of Y-27632. Cell viability, growth and phenotype were monitored with LIVE/DEAD®, MTS, qRT-PCR, and immunocytochemical assays. RESULTS: Cells from six LuCaP xenografts formed proliferating spheroids that were serially passaged a minimum of three times and cryopreserved. Two of the cell lines, LuCaP 136 and LuCaP 147, were further passaged and characterized. Both expressed biomarkers characteristic of the xenografts of origin, were determined to be of independent origin by STR fingerprinting, and were free of mycoplasma. LuCaP 147 formed tumors similar to the original xenograft when injected into mice. CONCLUSIONS: The ability to culture LuCaP cells affords new opportunities for fast, cheap, and efficient preclinical studies and extends the value of the LuCaP xenograft models.

Preparing students to address the social determinants of health in integrated care settings.

BACKGROUND: Health professionals are increasingly being called to address the social determinants of health (SDOH) and, to do so effectively, often requires an integrated approach to care. As a result, accreditation standards across multiple professions have emphasised the importance of interprofessional education (IPE). APPROACH: This paper describes large-scale, community-engaged learning that is required annually of students from nursing, pharmacy, public health, and social work. Through a series of asynchronous and synchronous activities that are informed by the Interprofessional Education Collaborative core competencies, students are trained to be SDOH change makers who can readily adopt integrated care service delivery frameworks into their future practice. EVALUATION: Approximately 1000 students have participated in this event since the University launched its IPE curriculum in 2017. Student consistently report achievement of the course learning objectives, with 91% of students reporting that the learning activities enhanced their understanding of their professional roles/responsibilities in regards to addressing poverty and food insecurity. IMPLICATIONS: Two key lessons learned from these efforts are described, including the benefits of a trauma-informed pedagogical approach and special considerations for large-scale learning.

Transcript levels of androgen receptor variant AR-V1 or AR-V7 do not predict recurrence in patients with prostate cancer at indeterminate risk for progression.

PURPOSE: AR-V7, a ligand independent splice variant of androgen receptor, may support the growth of castration resistant prostate cancer and have prognostic value. Another variant, AR-V1, interferes with AR-V7 activity. We investigated whether AR-V7 or V1 expression would predict biochemical recurrence in men at indeterminate (about 50%) risk for progression following radical prostatectomy. MATERIALS AND METHODS: AR-V7 and V1 transcripts in a mixed grade cohort of 53 men in whom cancer contained 30% to 70% Gleason grade 4/5 and in a grade 3 only cohort of 52 were measured using a branched chain DNA assay. Spearman rank correlations of the transcripts, and histomorphological and clinical variables were determined. AR-V7 and V1 levels were assessed as determinants of recurrence in the mixed grade cohort by logistic regression and survival analysis. The impact of TMPRSS2-ERG gene fusion on prognosis was also evaluated. RESULTS: Neither AR-V7 nor V1 levels in grade 3 or 4/5 cancer in the mixed grade cohort were associated with recurrence or time to recurrence. However, AR-V7 and V1 inversely correlated with serum prostate specific antigen and positively correlated with age. The AR-V1 level in grade 3 cancer in the grade 3 only cohort was higher than in grade 3 or grade 4/5 components of mixed grade cancer. TMPRSS2-ERG fusion was not associated with AR-V7, AR-V1 or recurrence but it was associated with the percent of grade 4/5 cancer. CONCLUSIONS: The AR-V1 or V7 transcript level does not predict recurrence in patients with high grade prostate cancer at indeterminate risk for progression. Grade 3 cancer in mixed grade tumors may differ from 100% grade 3 cancer, at least in AR-V1 expression.

Experiential education accommodations for students with disabilities in United States pharmacy schools: An exploratory study.

INTRODUCTION: We sought to identify challenges and possible outcomes for pharmacy schools providing accommodations on experiential rotations for students with disabilities. METHODS: A survey was developed and sent to the experiential education departments of pharmacy schools across the nation and anonymous responses were collected. Quantitative survey results were assessed using descriptive statistics, and qualitative results were assessed using thematic analysis. RESULTS: A total of 43 individuals who self-identified as current members of the experiential education department of their school responded to the survey. Student, preceptor, and institutional challenges and barriers were identified, and various approaches to providing accommodations for students with disabilities during experiential rotations were described. CONCLUSIONS: Providing accommodations for students on experiential rotations remains a challenge for pharmacy programs. However, guidance for pharmacy schools on proper support of students with disabilities on experiential rotations remains limited.

Barriers and facilitators for screening and treatment of hyperlipidemia among patients with inflammatory arthritis.

BACKGROUND: Patients with inflammatory arthritis (IA), defined as rheumatoid arthritis (RA) and psoriatic arthritis (PsA), are at increased risk for cardiovascular disease (CVD). The frequency of screening and treatment of hyperlipidemia, a modifiable CVD risk factor, is low in these patients. The reasons for low screening and treatment rates in this population are poorly understood. Our objective was to elicit the barriers and facilitators for screening and treatment of hyperlipidemia from the perspective of patients with IA. METHODS: We conducted a qualitative study using focus groups of patients with IA, guided by Bandura's Social Cognitive Theory. We recruited patients with IA aged 40 years and older from a single academic center. Data were analyzed thematically. RESULTS: We conducted three focus groups with 17 participants whose mean age was 56 (range 45-81) years; 15 were women. Four themes emerged as barriers: 1) need for more information about arthritis, prognosis, and IA medications prior to discussing additional topics like CVD risk; 2) lack of knowledge about how IA increases CVD risk; 3) lifestyle changes to reduce overall CVD risk rather than medications; and 4) the need to improve doctor-patient communication about IA, medications, and CVD risk. One theme emerged as a facilitator: 5) potential for peer coaches (patients with IA who are trained about concepts of CVD risk and IA) to help overcome barriers to screening and treatment of hyperlipidemia to lower CVD risk. CONCLUSION: Patients with IA identified educational needs about IA, increased CVD risk in IA and the need for improved doctor-patient communication about screening for hyperlipidemia and its treatment. Patients were receptive to working with peer coaches to facilitate achievement of these goals.

Common and Challenging Behaviors Among Individuals on Long-term Opioid Therapy.

OBJECTIVE: Long-term opioid therapy (LTOT) is commonly prescribed for chronic pain, despite risks such as opioid use disorder (OUD) and overdose. Caring for patients on LTOT can be difficult, given lack of evidence about assessment of challenging behaviors among patients on LTOT. To develop this evidence, a critical first step is to systematically identify the common and challenging behaviors that primary care providers encounter among patients on LTOT, and also to highlight to diverse range of behaviors encountered. METHOD: We conducted a Delphi study in 42 chronic pain experts to determine consensus on how to address the top common and challenging behaviors. This paper reports on the first round of the study, which elicited a range of behaviors. We conducted thematic analysis of the behaviors and also used the Diagnostic and Statistical Manual (DSM)-5 criteria for OUD as a priori codes. RESULTS: In all, 124 unique behaviors were identified by participants and coded into 4 thematic categories: concerning behaviors that map onto DSM-5 criteria for OUD, and those that do not which were: behaviors that suggest deception, signs of diversion, and nonadherence to treatment plan. Those behaviors that fell outside of OUD criteria we identified as "gray zone" behaviors. CONCLUSIONS: While some of these challenging behaviors fall under the criteria for an OUD, many fall outside of this framework, making diagnosis and treatment difficult, and consensus on how to deal with these "gray zone" behaviors is vital. Future research should explore how these "gray zone" behaviors can best be assessed and managed in a primary care setting.

Managing Opioids, Including Misuse and Addiction, in Patients With Serious Illness in Ambulatory Palliative Care: A Qualitative Study.

BACKGROUND: Pain and opioid management are core ambulatory palliative care skills. Existing literature on how to manage opioid misuse/use disorder excludes patients found in palliative care settings, such as individuals with serious illness or those at the end of life. OBJECTIVES: We conducted an exploratory study to: (1) Identify the challenges palliative care clinicians face when prescribing opioids in ambulatory settings and (2) explore factors that affect opioid decision-making. METHODS: We recruited palliative care clinicians who prescribe opioids in ambulatory settings, which included open-ended questions and was conducted online. Results were analyzed qualitatively using a content analysis-based approach. RESULTS: Eighty-three palliative care clinicians (mostly MDs/DOs) participated. Challenges faced when prescribing opioids included clinician differences in approach to care (eg, transitioning from another clinician with more permissive opioid prescribing), medication access (eg, inadequate pharmacy supply), resource constraints (eg, access to mental health and addiction expertise), managing problems outside the typical palliative care scope (eg addiction). Participants also discussed factors that influenced their opioid prescribing decisions, such as opioid-related harms and risks that they need to weigh; they also spoke about the necessity of considering other factors like the patient's environment, disease, treatment, and prognosis. CONCLUSION: This study highlights the challenge of opioid management in patients with serious illness, particularly when misuse or substance use disorder is present, and suggests areas for future research focus. Our next step will be to establish consensus on approaches to opioid prescribing decision-making and policy in seriously ill patients presenting to ambulatory palliative care.

Toward a Core Domain Set for Glucocorticoid Impact in Inflammatory Rheumatic Diseases: The OMERACT 2018 Glucocorticoid Impact Working Group.

OBJECTIVE: To understand the effects of glucocorticoids (GC), which are of importance to patients. METHODS: The results of 2 literature reviews, a patient survey, and a qualitative study were presented. RESULTS: No validated instrument exists to evaluate GC effect on patients. Survey data revealed skin thinning/bruising, sleep disturbance, and weight gain as the most frequent adverse effects. The qualitative research yielded rich data covering rapid benefits and physical and emotional consequences of GC. CONCLUSION: It was agreed that a patient-reported outcome to measure GC effect was required and a research agenda was developed for this goal.

Consensus-Based Treatment Approaches for Managing Concerning Behaviors in Patients on Long-term Opioid Therapy for Chronic Pain: Case-Based Applications.

Guidelines recommend careful monitoring of patients on long-term opioid therapy for chronic pain to assess for concerning medication-taking behaviors that may signal opioid misuse or the presence of a substance use disorder. However, specific management strategies to guide providers if concerning medication-taking behaviors emerge are lacking. Therefore, we recruited a Delphi panel-42 experts in chronic pain and opioid prescribing-to develop consensus-based treatment approaches to guide management of the 6 most common and concerning behaviors identified: missing prescriber appointments, taking opioids for symptoms other than pain, using more opioid medication than prescribed, asking for an increase in opioid dose, aggressive behavior, and alcohol and other substance use. The results of that process are published as a separate study. The purpose of the present study was to present clinical cases in which concerning medication-taking behaviors arise in the course of long-term opioid therapy and demonstrate for readers how the Delphi panel's consensus-based approaches could be applied.

Intervention Mapping to develop a Social Cognitive Theory-based intervention for chronic pain tailored to individuals with HIV.

Chronic pain is an important comorbidity among individuals with HIV. Behavioral interventions are widely regarded as evidence-based, efficacious non-pharmacologic interventions for chronic pain in the general population. An accepted principle in behavioral science is that theory-based, systematically-developed behavioral interventions tailored to the unique needs of a target population are most likely to be efficacious. Our aim was to use Intervention Mapping to systematically develop a Social Cognitive Theory (SCT)-based intervention for chronic pain tailored to individuals with HIV that will improve pain intensity and pain-related functional impairment. Our Intervention Mapping process was informed by qualitative inquiry of 24 patients and seven providers in an HIV primary care clinic. The resulting intervention includes group and one-on-one sessions and peer and staff interventionists. We also developed a conceptual framework that integrates our qualitative findings with SCT-based theoretical constructs. Using this conceptual framework as a guide, our future work will investigate the intervention's impact on chronic pain outcomes, as well as our hypothesized proximal mediators of the intervention's effect.

Management of problematic behaviours among individuals on long-term opioid therapy: protocol for a Delphi study.

INTRODUCTION: Given the sharp rise in opioid prescribing and heightened recognition of opioid addiction and overdose, opioid safety has become a priority. Clinical guidelines on long-term opioid therapy (LTOT) for chronic pain consistently recommend routine monitoring and screening for problematic behaviours. Yet, there is no consensus definition regarding what constitutes a problematic behaviour, and recommendations for appropriate management to inform front-line providers, researchers and policymakers are lacking. This creates a barrier to effective guideline implementation. Thus, our objective is to present the protocol for a Delphi study designed to: (1) elicit expert opinion to identify the most important problematic behaviours seen in clinical practice and (2) develop consensus on how these behaviours should be managed in the context of routine clinical care. METHODS/ANALYSIS: We will include clinical experts, defined as individuals who provide direct patient care to adults with chronic pain who are on LTOT in an ambulatory setting, and for whom opioid prescribing for chronic non-malignant pain is an area of expertise. The Delphi study will be conducted online in 4 consecutive rounds. Participants will be asked to list problematic behaviours and identify which behaviours are most common and challenging. They will then describe how they would manage the most frequently occurring common and challenging behaviours, rating the importance of each management strategy. Qualitative analysis will be used to categorise behaviours and management strategies, and consensus will be based on a definition established a priori. ETHICS/DISSEMINATION: This study has been approved by the Institutional Review Board (IRB) of the University of Alabama at Birmingham (UAB). This study will generate Delphi-based expert consensus on the management of problematic behaviours that arise in individuals on LTOT, which we will publish and disseminate to appropriate professional societies. Ultimately, our findings will provide guidance to front-line providers, researchers and policymakers.
