Equity in an Equal Access System? - Quality & Timeliness of Cancer Care in the Veterans Affairs Healthcare System

The objective of this dissertation was to examine the association between patients' race and receipt of National Comprehensive Cancer Network guideline-adherent and timely colorectal cancer (CRC) and non-small cell lung cancer (NSCLC) care in the Veterans Affairs (VA) healthcare system. Data were from the External Peer Review Program (EPRP) Special Study on CRC and NSCLC, originally purposed for performance monitoring, examined in an observational, retrospective study design. The sample consisted of African American (AA) and Caucasian patients diagnosed with CRC between 2003 and 2006 or NSCLC between 2006 and 2007 at VA hospitals nationwide. Statistical analysis approaches included multivariate logistic regression and survival analysis methods. Our first analysis used multivariable logistic regression to examine associations between race and receipt of guideline-concordant care (computed tomography scan, preoperative carcinoembryonic antigen, clear surgical margins, medical oncology referral for Stages II-III; fluorouracil-based adjuvant chemotherapy for Stage III; surveillance colonoscopy for Stages I-III). There were no significant racial differences in receipt of guideline-concordant CRC care. Our second analysis examined associations between race and CRC care timeliness. There were no racial differences in time to chemotherapy initiation (HR 0.82, p=0.61) or surgery to death (HR 0.94, p=0.0.49). Caucasian race was protective for shorter time to first surveillance colonoscopy (HR 0.63, p=0.02). On average, the difference in time to colonoscopy was sixteen days. Our third analysis examined associations between race and NSCLC care timeliness. There were no racial differences in time to initiation of treatment (72 days for AA versus 65 days for Caucasian patients, HR 1.03, p=0.80) or palliative care or hospice referral (129 versus 116 days, HR 1.10, p=0.34). However, the adjusted model found longer survival for African American compared to Caucasian patients (133 versus 117 days, HR 1.31, p=0.00). In these data there were minimal statistically significant racial differences. We identified no clinically meaningful racial differences in cancer care quality, timeliness, or patient outcomes. This suggests that VA may be a leader in providing equitable cancer care. Future studies could examine causal pathways for the VA's equal, quality care and ways to translate the VA's success into other hospital systems.Doctor of Philosoph

Life satisfaction among a clinical eating disorder population

Background The primary objective was to understand life satisfaction (LS) of patients with eating disorders (EDs) in relation to eating pathology severity, personal/familial ED history, and key demographic and anthropometric variables. Methods Participants (N = 60) completed the Satisfaction with Life Scale (SWLS), the Eating Pathology Severity Index (EPSI), and demographic questionnaires. Bivariate associations via correlations and multiple linear regression models were used to explore these relationships. Results The SWLS mean score was 3.7 out of 7, suggesting it is below the population-based norm. LS was positively statistically significantly associated with private insurance, past ED, EPSI muscle building, EPSI restricted eating, and EPSI negative attitudes. When included in multiple linear regression, the model explained 33% of the variability of LS [F (7, 56) = 3.4, p = 0.0054, R2 = 0.33]. EPSI muscle building remained the strongest predictor (β = 0.13, p = 0.04). Conclusions Based on the data, individuals who have/have had EDs scored lower on the SWLS than the general population. Individuals scoring within this range typically experience significant issues in several areas of life or a substantial issue in one area

Adverse Childhood Experiences Among Females in Substance Use Treatment and Their Children: A Pilot Study

Women with substance use disorder (SUD) often have experienced adverse childhood experiences (ACEs). The intergenerational nature of ACEs also put their children at risk for experiencing ACEs. However, no research has explored the prevalence of ACEs in children whose mothers have SUD. This study assessed ACE scores in mothers with SUD and their children and compared them with non-SUD participants. Females with SUD were recruited from a treatment center (n = 50) and compared to females without SUD from the same area (n = 50). The ACE scores of the participants and their children were measured as well as sociodemographic variables. ANOVA and Fisher’s Exact tests were used to examine univariate differences. Multivariate regression models assessed the difference in ACE scores between the groups and their children and the relationship between maternal and child ACE scores while including sociodemographic confounders. The mean ACE score was significantly higher in SUD participants (4.9, SD = 2.9) when compared to non-SUD participants (1.9, SD = 2.0) after controlling for sociodemographic variables (p \u3c .01). Children of treatment participants also had significantly higher mean ACE scores (3.9, SD = 2.3) than children of comparison participants (1.3, SD = 2.0, p \u3c .01). Maternal ACE score was positively related to children’s ACE score after controlling for sociodemographic variables. Given the intergenerational nature of ACEs and their high burden in both mothers and children in substance use treatment, these preliminary findings suggest that mother–child trauma-informed interventions may be appropriate for this population

Barriers to using new needles encountered by rural Appalachian people who inject drugs: implications for needle exchange

Background Using a new needle for every injection can reduce the spread of infectious disease among people who inject drugs (PWID). No previous study has examined new needle use barriers among PWIDs residing in the rural Appalachian part of the United States, an area currently in the midst of a heroin epidemic. Objective Therefore, our primary aim was to explore self-reported barriers to using a new needle by PWID attending a needle exchange program (NEP). Methods We conducted a cross-sectional survey of PWID attending two NEPs in rural West Virginia located in the heart of Central Appalachia. A convenience sample of PWID (n = 100) completed the Barriers to Using New Needles Questionnaire. Results The median number of barriers reported was 5 (range 0–19). Fear of arrest by police (72% of PWID “agreed” or “strongly agreed”) and difficulty with purchasing needles from a pharmacy (64% “agreed” or “strongly agreed”) were the most frequently cited barriers. Conclusions/Importance Congruent with previous findings from urban locations, in rural West Virginia, the ability of PWID to use a new needle obtained from a needle exchange for every injection may be compromised by fear of arrest. In addition, pharmacy sales of new needles to PWID may be blunted by an absence of explicit laws mandating nonprescription sales. Future studies should explore interventions that align the public health goals of NEPs with the occupational safety of law enforcement and health outreach goals of pharmacists

Scalability of effective adherence interventions for patients using cardiovascular disease medication:A realist synthesis-inspired systematic review

Upscaling of medication adherence interventions to routine care is still challenging. This realist theory-inspired review aimed to assess which intervention aspects are potentially important for the scalability of effective cardiovascular disease (CVD) medication adherence interventions and how they are reported in effectiveness studies. A total of 4097 articles from four databases were screened of which ultimately 31 studies were included. Relevant information on scalability was extracted using a theoretic framework based on the scalability assessment tool used in the QUALIDEC study for the following domains: (i) innovation, (ii) implementers and patients, (iii) adopting organizations and health system, and (iv) socio-political context. Extracted articles were analysed for themes and chains of inference, which were grouped based on commonality and source of evidence to form new hypotheses. Six different domains relevant for scalability of adherence interventions were identified: (1) Complexity of the intervention; (2) training; (3) customization of the intervention; (4) drivers of the intervention; (5) technical interventions; and (6) stakeholder involvement. These six domains might be useful for the development of more scalable interventions by bridging the gap between research and practice. Data relevant for scalability is not well reported on in effectiveness trials for CVD medication adherence interventions and only limited data on scalability has been published in additional papers. We believe the adoption and reach of effective CVD medication adherence interventions will improve with increased awareness for the necessity of scalability in all phases of intervention development

Qualitative case study of needle exchange programs in the Central Appalachian region of the United States

Background The Central Appalachian region of the United States is in the midst of a hepatitis C virus epi- demic driven by injection of opioids, particularly heroin, with contaminated syringes. In response to this epidemic, several needle exchange programs (NEP) have opened to pro- vide clean needles and other supplies and services to people who inject drugs (PWID). How- ever, no studies have investigated the barriers and facilitators to implementing, operating, and expanding NEPs in less populous areas of the United States. Methods This qualitative case study consisted of interviews with program directors, police chiefs, law enforcement members, and PWID affiliated with two NEPs in the rural state of West Virginia. Interview transcripts were coded inductively and analyzed using qualitative data analysis software. Final common themes related to barriers and facilitators of past program open- ings, current program operations, and future program plans, were derived through a consen- sus of two data coders. Results Both NEPs struggled to find existing model programs, but benefited from broad community support that facilitated implementation. The largest operational barrier was the legal conun- drum created by paraphernalia laws that criminalize syringe possession. However, both PWID and law enforcement appreciated the comprehensive services provided by these pro- grams. Program location and transportation difficulties were additional noted barriers. Future program operations are threatened by funding shortages and bans, but necessitated by unexpected program demand. Conclusion Despite broad community support, program operations are threatened by growing partici- pant volumes, funding shortages, and the federal government’s prohibition on the use of funds to purchase needles. Paraphernalia laws create a legal conundrum in the form of criminal sanctions for the possession of needles, which may inadvertently promote needle sharing and disease transmission. Future studies should examine additional barriers to using clean needles provided by rural NEPs that may blunt the effectiveness of NEPs in pre- venting disease transmission

Methodological approaches to study context in intervention implementation studies: an evidence gap map

Within implementation science studies, contextual analysis is increasingly recognized as foundational to interventions' successful and sustainable implementation. However, inconsistencies between methodological approaches currently limit progress in studying context and guidance to standardize the use of those approaches is scant. Therefore, this study's objective was to systematically review and map current methodological approaches to contextual analysis in intervention implementation studies. The results would help us both to systematize the process of contextual analysis and identify gaps in the current evidence.; We conducted an evidence gap map (EGM) based on literature data via a stepwise approach. First, using an empirically developed search string, we randomly sampled 20% of all intervention implementation studies available from PubMed per year (2015-2020). Second, we assessed included studies that conducted a contextual analysis. Data extraction and evaluation followed the Basel Approach for CoNtextual ANAlysis (BANANA), using a color-coded rating scheme. Also based on BANANA and on the Context and Implementation of Complex Interventions (CICI) framework-an implementation framework that pays ample attention to context- we created visual maps of various approaches to contextual analysis.; Of 15, 286 identified intervention implementation studies and study protocols, 3017 were screened for inclusion. Of those, 110 warranted close examination, revealing 22% that reported on contextual analysis. Only one study explicitly applied a framework for contextual analysis. Data were most commonly collected via surveys (n = 15) and individual interviews (n = 13). Ten studies reported mixed-methods analyses. Twenty-two assessed meso-level contextual and setting factors, with socio-cultural aspects most commonly studied. Eighteen described the use of contextual information for subsequent project phases (e.g., intervention development/adaption, selecting implementation strategies). Nine reported contextual factors' influences on implementation and/or effectiveness outcomes.; This study describes current approaches to contextual analysis in implementation science and provides a novel framework for evaluating and mapping it. By synthesizing our findings graphically in figures, we provide an initial evidence base framework that can incorporate new findings as necessary. We strongly recommend further development of methodological approaches both to conduct contextual analysis and to systematize the reporting of it. These actions will increase the quality and consistency of implementation science research

ESPACOMP Medication Adherence Reporting Guideline (EMERGE)

Research on assessing or managing medication adherence applies approaches from observational, interventional, and implementation science that spans many disciplines and demands coherent conceptualization, valid methods, appropriate analyses, and complete and accurate reporting. To ensure such reporting, the European Society for Patient Adherence, COMpliance, and Persistence (ESPACOMP) Medication Adherence Reporting Guideline (EMERGE) recommends standard reporting approaches based on an accepted taxonomy. This guideline is derived from a literature review, a reactive Delphi study with 26 medication adherence experts from many countries and disciplines, and feedback from ESPACOMP members. It is designed to supplement existing guidelines for health research reporting and is structured around 4 minimum reporting criteria and 17 items reflecting best reporting practice. By enhancing and harmonizing research reporting, EMERGE aims to advance research and, ultimately, patient outcomes
