Women's Motivators to Engage in Opioid Use Disorder Treatment While Enrolled in an Opioid Intervention Court.

IntroductionTo address the rising presence of opioid use disorder in the United States, states have begun to implement specialized opioid intervention courts to provide immediate support for individuals at risk of opioid overdose. The present study sought to understand the motivations of women to engage in treatment while enrolled in an opioid intervention court. MethodsWe conducted 31 in-depth, qualitative interviews with women enrolled in an opioid intervention court in Buffalo, NY, to better understand their motivation regarding opioid use treatment. The data indicated a combined social-ecological and self-determination theory framework. ResultsThematic analysis revealed four themes across the Social-Ecological Model that aligned with motivation-related needs of autonomy, competence, and relatedness, as defined by Self-Determination Theory. Themes at each level of the Social-Ecological Model described either support for or undermining of women's motivation for treatment: (1) individual level: personal motivation for change, (2) interpersonal level: support for OUD treatment-related autonomy, competence, and relatedness, (3) community level: court systems provide pathways to treatment, and (4) society level: insufficient social resources can undermine competence. ConclusionsThe findings provide new insights into various factors across all levels of the Social-Ecological Model that influence motivation for opioid use disorder treatment among women enrolled in opioid intervention court. Results support the possibility to integrate programs rooted in Self-Determination Theory to support opioid use disorder treatment among justice-involved persons.

Provider-Patient Communication on Pre-Exposure Prophylaxis (Prep) for HIV Prevention: An Exploration of Healthcare Provider Challenges.

Pre-exposure prophylaxis (PrEP) is a once-daily pill prescribed by healthcare providers to protect patients from contracting HIV. Current data suggests that a minority of healthcare providers have ever prescribed it to clinically-eligible patients. The present study employed a social ecological framework to understand the factors that influence providers' engagement in patient-centered communication regarding PrEP. Semi-structured interviews (N = 20) with physicians, physician assistants, and nurse practitioners working in primary and specialty care practices in Western New York were thematically analyzed to understand provider-based PrEP communication challenges. Although participants never prescribed PrEP, all had clinical experience with patient populations at risk for HIV, such as people who inject drugs, men who have sex with men, transgender women, and people who exchange sex for resources. Results revealed three themes affecting provider engagement in PrEP-related discussions, which emerged across three levels of the social ecological model. At the individual level, challenges affecting provider engagement in patient-centered discussions included lacking PrEP knowledge to educate and counsel patients and discomfort with prescribing PrEP based on its perceived newness. At the interpersonal level, participants expressed varying degrees of discomfort discussing HIV risk behaviors with patients. At the organizational level, providers expressed that time constraints and managing concurrent health conditions were competing clinical priorities. Findings indicate expanding implementation efforts will require multilevel interventions that target potential PrEP-adopting healthcare providers to mitigate the perceived and real challenges surrounding provider-patient communication on PrEP for HIV prevention. Practical implications are discussed.

Meta-Analysis of Alcohol and Serodiscordant Condomless Sex Among People Living with HIV.

While observational studies have found that alcohol consumption is associated with serodiscordant condomless sex among people living with HIV (PLHIV), no meta-analysis has yet examined this trend. We conducted a meta-analysis to synthesize empirical evidence on the association between alcohol and condomless sex with partners at risk of HIV acquisition. To meet inclusion criteria, studies: (1) specifically targeted PLHIV or provided stratified data for HIV-infected participants; (2) provided a quantitative measure of alcohol use; (3) provided a quantitative measure of condomless sex with serodiscordant partners; and (4) reported the results of statistical tests examining the relationship between alcohol use and serodiscordant condomless sex. Using random-effects models, weighted effect sizes were calculated. Three separate analyses were conducted to examine serodiscordant condomless sex in association with any alcohol consumption, binge/problematic drinking, and alcohol in a sexual context. A total of 36 independent effect sizes from 27 studies (including 25,065 HIV-infected participants) were pooled in the meta-analysis. Any alcohol consumption, binge/problematic drinking, and alcohol use in a sexual context were each associated with condomless sex with serodiscordant partners [OR 1.64 (95% CI 1.46-1.85); OR 1.65 (95% CI 1.14-2.39); OR 2.88 (95% CI 2.01-4.12), respectively]. Meta-analytic findings demonstrate a consistent positive relationship between alcohol use and serodiscordant condomless sex among PLHIV. Future public health programming for HIV-infected individuals needs to address the role of alcohol consumption in sexual risk-taking behavior.

Perspectives on Injectable HIV Pre-Exposure Prophylaxis: A Qualitative Study of Health Care Providers in the United States.

The introduction of injectable HIV pre-exposure prophylaxis (PrEP) has the potential to significantly change the biomedical HIV prevention landscape. However, effective implementation will require health care providers to adopt, prescribe, and administer injectable PrEP within clinical settings. This study qualitatively examined challenges and benefit of injectable PrEP implementation from the perspective of health care providers. From April to August 2022, we conducted 19 in-depth interviews with current PrEP-prescribing health care providers in New York State, including 3 physician assistants, 5 physicians, and 11 nurse practitioners. Interviews were audio-recorded, transcribed verbatim, and thematically analyzed to report semantic-level themes regarding injectable PrEP implementation. More than half of participants (61%) were aware of injectable PrEP; only 21% had experience prescribing it. Qualitative findings highlighted five themes. Three themes represented implementation challenges, including speculative concerns about side effects, appointment compliance, and practical and logistical considerations. The remaining two themes described benefits of injectable PrEP relative to oral PrEP, which included greater convenience and enhanced privacy. Findings from this qualitative study make significant applied contributions to the sparse knowledge on health care provider perspectives of injectable PrEP post-US Food and Drug Administration approval and their concerns and considerations regarding implementation in real-world clinical settings.

Lesbian, Gay, Bisexual, and Transgender (LGBT) Health Education in Healthcare Professional Graduate Programs: A Comparison of Medical, Nursing, and Pharmacy Students.

Relative to cisgender heterosexual persons, lesbian, gay, bisexual, and transgender (LGBT) people experience greater health inequities, thereby affecting their engagement in care. One strategy to address these disparities is to educate future healthcare professionals to provide nondiscriminatory care to LGBT people. The goal of this study was to explore the perceived coverage of LGBT health education topics in graduate-level medical (MD), pharmacy (PharmD) and nursing (DNP) curricula. Cross-sectional data were collected from web-based surveys (N = 733) completed by healthcare professional students enrolled at two universities in New York State. Of those who responded, 50.5% were MD, 38.9% were PharmD, and 10.6% were DNP students. Overall, mean scores indicated a dearth of perceived LGBT health coverage. Results demonstrated variations in coverage by degree program. Findings highlight the need to develop educational curricula inclusive of topics concerning LGBT patient health. Adequately educating the next generation of healthcare professionals can further promote healthcare engagement among LGBT persons and improve pedagogical practices in healthcare professional education programs.

Serostatus disclosure to sexual partners among people living with HIV: examining the roles of partner characteristics and stigma.

HIV serostatus disclosure among people living with HIV/AIDS (PLWHA) is an important component of preventing HIV transmission to sexual partners. Due to barriers like stigma, however, many PLWHA do not disclose their serostatus to all sexual partners. This study explored differences in HIV serostatus disclosure based on sexual behavior subgroup (men who have sex with men [MSM]; heterosexual men; and women), characteristics of the sexual relationship (relationship type and HIV serostatus of partner), and perceived stigma. We examined disclosure in a sample of 341 PLWHA: 138 MSM, 87 heterosexual men, and 116 heterosexual women who were enrolled in SafeTalk, a randomized, controlled trial of a safer sex intervention. We found that, overall, 79% of participants disclosed their HIV status to all sexual partners in the past 3 months. However, we found important differences in disclosure by subgroup and relationship characteristics. Heterosexual men and women were more likely to disclose their HIV status than MSM (86%, 85%, and 69%, respectively). Additionally, disclosure was more likely among participants with only primary partners than those with only casual or both casual and primary partners (92%, 54%, and 62%, respectively). Participants with only HIV-positive partners were also more likely to disclose than those with only HIV-negative partners, unknown serostatus partners, or partners of mixed serostatus (96%, 85%, 40%, and 60%, respectively). Finally, people who perceived more HIV-related stigma were less likely to disclose their HIV serostatus to partners, regardless of subgroup or relationship characteristics. These findings suggest that interventions to help PLWHA disclose, particularly to serodiscordant casual partners, are needed and will likely benefit from inclusion of stigma reduction components.

The impact of food insecurity on receipt of care, retention in care, and viral suppression among people living with HIV/AIDS in the United States: a causal mediation analysis.

Introduction: Attaining The Joint United Nations Programme on HIV/AIDS 95-95-95 targets to end the HIV epidemic by 2030 will require a greater understanding of the underlying mechanisms influencing care engagement among people living with HIV/AIDS (PLWHA). One such mechanism is food insecurity, defined as limited or uncertain access to food. Food insecurity has been shown to significantly impact HIV outcomes. Yet, few studies have examined the mechanisms through which food insecurity may influence these outcomes. We aimed to examine the effects of nutritional, behavioral, and mental health mechanisms through which food insecurity may impact HIV care continuum outcomes: receipt of care, retention in care, and viral suppression. Methods: We conducted a cross-sectional study of 200 PLWHA in New York State, United States from May-August 2022. Participants were recruited using convenience sampling methods. Multivariable logistic regression models were conducted to examine the associations between food insecurity and care continuum outcomes (receipt of care, retention in care, viral suppression), adjusting for age, race, ethnicity, education, income, and marital status. Individual causal mediation analyses were conducted to assess whether behavioral, mental health, and nutritional mechanisms mediated the hypothesized associations. Results: The median age of participants was 30 years (IQR: 27-37 years). The majority self-identified as Black (54.0%), male (55.5%) and straight/heterosexual (63.0%). Increasing severity of food insecurity was associated with greater odds of non-retention in care (aOR: 1.35, 95% CI: 1.07, 1.70) and viral non-suppression (aOR: 1.29, 95% CI: 1.08, 1.54). For the impact of food insecurity on non-retention in care, there was an indirect relationship (natural indirect effect; NIE) mediated through Body Mass Index (BMI) (ORNIE: 1.08, 95% CI: 1.00, 1.18). For viral non-suppression, there was an indirect relationship mediated through BMI (ORNIE: 1.07, 95% CI: 1.00,1.16) and an indirect relationship mediated through depression (ORNIE: 1.27, 95% CI: 1.07, 1.47). Discussion: Food insecurity was associated with greater odds of non-retention in care and viral non-suppression among PLWHA. Nutritional and mental health pathways are important mediators of these relationships. Results highlight the need for interventions to target these pathways to address food insecurity as an underlying mechanism influencing engagement in HIV care.

Infusing high-impact practices in undergraduate public health curricula: Models, lessons learned, and administrative considerations from two public universities.

High-impact practices (HIPs) can improve the rigor, quality, and outcomes of undergraduate education. Several high-impact practices are explicitly woven into the overarching goals, learning objectives, and curricular competencies for undergraduate public health degree programs, while others are natural fits. However, capitalizing on the value of HIPs for public health undergraduates requires a conscious effort in the process of curriculum design, course delivery, and administration of these programs. In this paper, we discuss both conceptual approaches and practical steps involved in the integration of HIPs in curriculum design and implementation. We discuss two exemplars of undergraduate programs that incorporate high-impact practices, illustrating how the same practices can be developed and implemented in different but equally effective ways across programs. We close with practical suggestions for designing or refining an undergraduate program to maximize the inclusion and effectiveness of high-impact practices.

Modern public pealth problems and solutions: An undergraduate capstone course to prepare the next generation of public health practitioners to enhance health equity.

With a growing emphasis on health equity in public health practice and research, ensuring a competent and skilled public health workforce is critical to advancing the public health mission of a healthier nation. The expansion of undergraduate public health programs provides a unique opportunity for more extensive training and education of the next generation of public health professionals and to center undergraduate public health education around the need to be competent in addressing health disparities to achieve health equity. Following national accreditation standards set by the Council on Education for Public Health (CEPH), undergraduate Bachelor of Public Health (BSPH) students at the University at Buffalo (UB) must complete a capstone course before graduation. This course focuses on integrating and synthesizing knowledge acquired from the BSPH core curriculum through analysis, explanation, and addressing public health problems via an interdisciplinary approach. We designed the most recent iterations of the capstone class based on the model that includes cross-cutting skills as defined by CEPH, evidence-based decision-making skills, established learning objectives of the course, and centering on health equity. This course also builds on the students' previously acquired knowledge with an ultimate goal to prepare the graduating seniors for the "real world" health equity-related public health activities. As a part of the coursework, students complete case studies, article reviews, and active learning group activities that target each component of the model. The final products of the course are a synthesis paper and oral presentation based on a public health problem as identified through surveillance data, analyzing causes of this problem, identifying critical stakeholders, creating an evidence-based solution to the problem, and explaining how health inequities may be addressed through the proposed solution. Centering the culminating course for BSPH undergraduate students on health equity will help ensure a competent and skilled workforce, informed by accreditation standards and prepared to lead our national public health goal of improved and equitable population health.

Socio-Structural Factors and HIV Care Engagement among People Living with HIV during the COVID-19 Pandemic: A Qualitative Study in the United States.

Achieving HIV prevention goals will require successful engagement in each stage of the HIV continuum. The present study sought to understand the ways in which socio-structural factors influence HIV care engagement among people living with HIV (PLH) within the context of the ongoing COVID-19 pandemic. Twenty-five PLH were recruited from January to October 2021. Semi-structured interviews discussed various socio-contextual factors that influenced engagement in HIV-related care as a result of the pandemic. A thematic content analysis reported semantic level themes describing factors influencing HIV care following an integrated inductive-deductive approach. Qualitative analysis revealed three themes that either supported or hindered engagement in care within the context of the COVID-19 pandemic: (1) social determinants of health, (2) social support, and (3) modes of healthcare delivery. The results underscore the need to assess socio-structural factors of health as means to promote successful engagement in the HIV care continuum and shed new insights to guide future practice in the era of COVID-19.

"I was 15 when I started doing drugs with my dad": Victimization, Social Determinants of Health, and Criminogenic Risk Among Women Opioid Intervention Court Participants.

The presence and severity of childhood and adult victimization increase the likelihood of substance use disorder (SUD), crimes, antisocial behaviors, arrests, convictions, and medical and psychiatric disorders among women more than men. These problems are compounded by the impact of social determinants of health (SDH) challenges, which include predisposition to the understudied, dramatic increase in opioid dependence among women. This study examined victimization, related SDH challenges, gender-based criminogenic risk factors for female participants, and public health opportunities to address these problems. We recruited women from the first national Opioid Intervention Court, a fast-track SUD treatment response to rapidly increasing overdose deaths. We present a consensual qualitative research analysis of 24 women Opioid Intervention Court participants (among 31 interviewed) who reported childhood, adolescent, and/or adult victimization experiences in the context of substance use and recovery, mental health symptoms, heath behaviors, and justice-involved trajectories. We iteratively established codes and overarching themes. Six primary themes emerged: child or adolescent abuse as triggers for drug use; impact of combined child or adolescent abuse with loss or witnessing abuse; adult abduction or assault; trajectory from lifetime abuse, substance use, and criminal and antisocial behaviors to sobriety; role of friends and family support in recovery; and role of treatment and opioid court in recovery, which we related to SDH, gender-based criminogenic factors, and public health. These experiences put participants at risk of further physical and mental health disorders, yet indicate potential strategies. Findings support future studies examining strategies where courts and health systems could collaboratively address SDH with women Opioid Intervention Court participants.

Female Opioid Court Participants' Narratives of Siloed Medical, Legal, and Social Service Sector Interactions to Inform Future Integrated Interventions.

A gap exists regarding how to design gender-specific interventions for women charged with opioid use disorder (OUD)-related crimes. National recent efforts include opioid courts. Treatment courts present opportunities for earlier intervention for women under judicial supervision. We interviewed 31 female participants in the first known opioid court so they could inform cross-sector integrated approaches to address their needs. Data reveal the complexity of participants' involvement with myriad cross-sector organizations, given the duality of their roles as simultaneous lifetime victims and as OUD-related perpetrators. Participants have difficulty trusting systems intended to help them due to systematic failures to prevent or address abuse and neglect over their lifetimes. The opioid crisis cannot be solved without an understanding of early missed intervention opportunities and a cross-sector approach.

"I think everybody should take it if they're doing drugs, doing heroin, or having sex for money": a qualitative study exploring perceptions of pre-exposure prophylaxis among female participants in an opioid intervention court program.

BACKGROUND: Women's rise in opioid use disorder has increased their presence in the criminal justice system and related risk behaviors for HIV infection. Although pre-exposure prophylaxis (PrEP) is an effective biomedical HIV prevention treatment, uptake among this high-risk population has been particularly low. Considerably little is known about the interplay between justice-involved women with opioid use disorder and HIV prevention. The aim of this study was to explore PrEP knowledge, attitudes, and perceptions for personal and partner use among women participants in the nation's first ever opioid intervention court program. METHODS: The authors conducted semi-structured, in-depth interviews with 31 women recruited from an Opioid Intervention Court, a recent fast-track treatment response to combat overdose deaths. We utilized a consensual qualitative research approach to explore attitudes, perceptions, and preferences about PrEP from women at risk for HIV transmission via sexual and drug-related behavior and used thematic analysis methods to code and interpret the data. RESULTS: PrEP interest and motivation were impacted by various factors influencing the decision to consider PrEP initiation or comfort with partner use. Three primary themes emerged: HIV risk perceptions, barriers and facilitators to personal PrEP utilization, and perspectives on PrEP use by sexual partners. CONCLUSIONS: Findings suggest courts may provide a venue to offer women PrEP education and HIV risk assessments. Study findings inform public health, substance use, and criminal justice research and practice with justice-involved participants experiencing opioid use disorder on the development of gender-specific PrEP interventions with the ultimate goal of reducing HIV incidence.

Integrative Approaches to the Undergraduate Public Health Major Curriculum: Strengths, Challenges, and Examples.

Many "first generation" undergraduate public health degree programs were designed based on "siloed" course structures centered around subunits in the discipline (e.g., Introduction to Epidemiology, Introduction to Environmental Health) that may be meaningful primarily to experts in the field. An alternative to the siloed approach is an integrative curricular design, in which courses are designed around meaningful thematic units (e.g., explaining public health problems, asking and answering scientific questions in public health), with an emphasis on drawing connections between knowledge from different but complementary disciplinary areas as a means to improve student learning and retention. The integrative approach shifts the curriculum conversation to capitalize on the interdisciplinary roots of the public health profession. This approach is consistent with the learning outcome recommendations in the Framing the Future Task Force report and in the CEPH requirements for the undergraduate public health major. We explore integrative approaches to developing curricular models for undergraduate public health programs and discuss both pedagogical and career preparation arguments supporting an integrative curriculum approach. These include facilitating the often-challenging task for students of seeing how concepts interrelate, making transparent how "basic" knowledge in the discipline relates to "real world" applications of the content, and better mirroring how professionals in the discipline actually use knowledge in practice. Finally, we review examples of core concepts and features in an integrative curriculum approach to the undergraduate public health major as an effective educational program with high-quality, learner-centered educational experiences.

Awareness, knowledge, and attitudes towards human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) among pharmacy students.

INTRODUCTION: The purpose of this study was to assess pharmacy students' awareness, knowledge, and perceptions towards human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP), confidence and intentions to counsel patients on PrEP, and preferred PrEP training. METHODS: A web-based cross-sectional survey was conducted with pharmacy students. Descriptive statistics and multivariate logistic regressions were performed. RESULTS: Ninety-one percent of participants were aware of PrEP and 61% were familiar with PrEP prescription guidelines. In multivariate analysis, greater PrEP knowledge, attitudes towards PrEP, and familiarity with prescribing guidelines were significantly associated with confidence in PrEP counseling (p < 0.01 for all). Males had significantly higher odds of reporting confidence in PrEP counseling relative to their female counterparts (p < 0.01). Relative to fourth year students, second year students were less likely to report confidence in PrEP counseling (p < 0.01). Participants who were familiar with prescribing guidelines had significantly higher odds of PrEP counseling intentions (p < 0.05). Preferred educational topics regarding PrEP included training on side effects and adherence monitoring (65% and 51%, respectively). The most preferred modalities for receiving PrEP education were online education (47%), educational seminars in required courses (43%), and self-study modules (39%). CONCLUSIONS: Given the key role played by pharmacists in patient engagement, they may be presented with opportunities to provide PrEP counseling and education. The development of educational modules for pharmacy students in an effort to increase PrEP uptake should consider addressing gaps in knowledge and preferred training modalities.

Comparing algorithms for composite measures of intra-disease multiple medication adherence: The case of diabetes.

BACKGROUND: Adherence to multiple medications (i.e., separate dosage forms) intended for a disease can be measured by different single estimators, termed as composite estimators of intra-disease multiple medication adherence: 80% days covered (a) by at least one medication ("at least one"); (b) by both medications ("both"); (c) by each medication measured separately ("all"); and (d) computing an average of the individual medication adherence estimates ("average"). OBJECTIVES: (a) Assess different composite adherence estimators regarding their ability to predict healthcare utilization; (b) compare and contrast composite estimators. METHODS: Using MarketScan 2002-2003 data, 6043 nonelderly patients who filled separate prescriptions of sulfonylurea [SU] and thiazolidinedione [TZD] were identified. Adherence was measured by the proportion of days covered (PDC) over periods of 90 days, 30 days, and cumulatively over such periods. Cox proportional hazards models analyzed all-cause and diabetes-related emergency room (ER) visits as the outcome variables. RESULTS: All composite measures predicted hazards of all-cause or diabetes ER visits (P < 0.001) and each measure showed statistically significant discriminatory power (concordance statistics from 0.55 to 0.58). Cox regression was performed multiple times in which composite estimators measured on a continuous scale (e.g., 'average') were dichotomized using several cut-points. In the majority of cases (≤3 out of 8 times in analyses of ER outcomes), optimal results did not occur when the dichotomization cut-point was set at 80%. CONCLUSIONS: Each composite estimator showed the fundamental quality of a good measure. Although 'average' and 'all' approaches offer ease of measurement, there was no clear trend in superiority of one measure over the others. Clinical and practical considerations should dictate the choice of measure.

University student perceptions about the motives for and consequences of nonmedical use of prescription drugs (NMUPD).

OBJECTIVE: The purpose of the current study was to increase qualitative understanding of student motives for and consequences associated with nonmedical use of prescription drugs. PARTICIPANTS: Sixty-one students participated in eight focus groups between April and November 2013. METHODS: Students described prescription drugs commonly used for nonmedical reasons, as well as the motives for and consequences associated with their use. Data were analyzed using thematic content analysis. RESULTS: Students reported stimulants as the most commonly used prescription drug for nonmedical reasons, least expensive, and easiest to obtain on campus, followed by benzodiazepines. Opioids were less commonly used, more expensive, and difficult to acquire. Motives and consequences varied by prescription drug class. CONCLUSIONS: Our qualitative findings extend previous research by suggesting differences in students' perceived motives for using and consequences associated with the different classes of prescription drugs. These findings provide implications for the development of preventive interventions.

The Proximal Effects of Acute Alcohol Consumption on Male-to-Female Aggression: A Meta-Analytic Review of the Experimental Literature.

The current meta-analytic review examined the experimental literature to quantify the causal effect of acute alcohol consumption on self-reported and observed indicators of male-to-female general, sexual, and intimate partner aggression. Database and reference list searches yielded 22 studies conducted between 1981 and 2014 that met all criteria for inclusion and that were subjected to full text coding for analysis. Results detected a significant overall effect (d = .36), indicating that male participants who consumed alcohol evidenced greater aggressive behavior toward females while completing a subsequent laboratory aggression paradigm than male participants who received no alcohol. We found homogeneity across all categories of potential moderator variables. Results further indicated that alcohol resulted in comparable increases of male-to-female sexual (d = .32) and intimate partner (d = .45) aggression. Further research is required to draw meaningful conclusions about individual and situational factors that may interact with acute alcohol consumption to produce the highest levels of risk.

Feasibility and Acceptability of a Smartphone App for Daily Reports of Substance Use and Antiretroviral Therapy Adherence among HIV-Infected Adults.

While substance use is one of the most consistent predictors of poor adherence to antiretroviral therapy (ART), few studies among people living with HIV (PLH) have utilized mobile phone-based assessment of these health behaviors. PLH were recruited from primary care clinics to report ART and substance use using a smartphone application (app) for 14 consecutive days. The app's feasibility as a data collection tool was evaluated quantitatively via surveys and qualitatively via in-depth interviews to assess daily report completion, compliance, and study satisfaction. Overall, 26 participants (M = 49.5 years, 76% male) completed 95.3% of time-based daily reports. Participants reported high satisfaction with the app and expressed future interest in using smartphones to report daily behaviors. High completion rates and participant acceptability suggest that smartphones are a feasible, acceptable method for collecting substance use and ART data among PLH. Potential areas of concern such as sufficient training and assistance for those with limited smartphone experience should be considered for future app-based research studies among PLH.

Adherence to multiple medications prescribed for a chronic disease: a methodological investigation.

BACKGROUND: Many patients receive multiple medications for the treatment of a disease. While monitoring adherence is important, a composite measure of adherence is useful for estimating adherence to multiple medications in these patients. There are multiple ways to compute composite estimates of adherence to multiple medications, including (a) 80% of days covered by at least 1 medication ("at least 1"); (b) 80% of days covered by both medications ("both"); (c) 80% of days covered by each medication measured separately ("all"); and (d) computing an average of the individual medication adherence estimates ("average"). Comparison of adherence rates to individual medications and that of composite estimates are important for intervention decisions and effective disease management.  OBJECTIVES: To (a) examine adherence to multiple medications prescribed for a disease; (b) estimate composite adherence to multiple medications prescribed for a disease; and (c) determine the rate of differential classification of a patient being adherent as is estimated by different available algorithms.   METHODS: A retrospective cohort study was designed using 2002-2003 MarketScan Commercial Claims and Encounters data. To be included in the cohort, patients had to be less than aged 65 years and had to have separate prescriptions filled for 2 classes of diabetes medications (i.e., any sulfonylurea [SU] and any thiazolidinedione [TZD]) at least once; patients taking other diabetic medications over the observation period were excluded. Adherence was measured by proportion of days covered (PDC) over periods of 90 days (8 quarters total) and cumulatively over the 2-year study period. For some composite adherence estimates, patients were considered adherent if PDC ≥ 80%. Survival curves using the life-table method were constructed to compare the time until PDC became less than 80% as estimated by the 3 different categorical composite measures. RESULTS: A total of 6,043 patients were included in the analysis. Across the 8 quarters under consideration, the average PDC estimates ranged between 69.8%-84.2% for SUs and 70.3%-85.6% for TZDs. The mean composite PDC based on the average algorithm varied between 69.4% and 84.9% when measured over each quarter or cumulatively. Similarly, the rates of composite adherence ranged from 74.5% to 88.2%, 46.4% to 61.2%, and 47.7% to 62.9% for the "at least 1," "both," and "all" methods, respectively. Many subjects were classified as adherent by 1 composite dichotomous measure but not by all 3 dichotomous measures (i.e., "all," "at least 1," and "both"); of these patients, 30.6%-38.2% were classified differently as to their adherence status over different quarters by different measures. Survival curves of categorical composite measures were different (P less than 0.05) from one another. "At least 1" identified more patients as persistent and showed a much slower decline than did the "all" or "both" approaches.  CONCLUSIONS: Subjects were found to have a level of adherence-as estimated by individual medication adherence and composite adherence metrics-for multiple medications prescribed for a disease that, while not optimal from the perspective of patient care, was not entirely poor. In addition, composite estimates of adherence considerably varied depending on algorithms used. Most importantly, a large number of patients appeared to be subject to inconsistent classification based on adherence measurement algorithm. Adherence estimates produced by different composite measurement approaches give rise to difficulty in consistent interpretation, which may be detrimental to appropriate patient care decision making.
