Providers' Use of Pharmacogenetic Testing to Inform Antidepressant Prescribing: Results of Qualitative Interviews

OBJECTIVE

Pharmacogenetic testing (PGx) for patients experiencing depression has been associated with modest improvements in symptoms. However, little is known about providers' use of PGx, including how and for whom providers use the test results in clinical decision making. In this article, results from qualitative interviews on the experience of providers participating in a pragmatic trial of PGx are described; implications of the providers' experiences are highlighted to inform future implementation of PGx.

METHODS

Interviews were conducted with providers participating in the trial (N=61) who treated veterans who had depression. Questions were informed by the Consolidated Framework for Implementation Research. A rapid analytic approach was used.

RESULTS

Two main themes were identified: perceptions regarding which patients would likely benefit from PGx and approaches to using the test results in prescribing. Providers generally expressed positive experiences with using PGx results. However, the providers varied in application of the test results to clinical decision making regarding medications, were uncertain about how much to rely on the results, and differed in perceptions about which patients would benefit from PGx.

CONCLUSIONS

To support future implementation, policies and procedures are needed, as well as mechanisms to support ongoing provider education on PGx.

"I just wanna be another person at school": Disclosing veteran identity on campus and effects on campus engagement

Objective: To describe how veterans feel about disclosing their military status on campus and impacts on engagement with social and health-related services. Participants: Thirty-one university student veterans who participated in a student veterans' health study. Participants self-identified as White and male (90%) with an average age of 29.5 years and 6.7 years of military service. Methods: Qualitative interviews explored veterans' perceptions of belonging on campus and the impact of veteran identity on educational experiences. Data analysis used an inductive, content-based approach. Results: Themes included: (1) varied feelings around disclosing military service history, with many preferring not to disclose; (2) visibility of resources on campus; and (3) use of resources on campus for social engagement, mental, and physical health. Conclusions: Findings illustrate student veterans' complex experiences, and how feelings about disclosing veteran identity on campus relate to resource use. Campuses should acknowledge and explore this complexity with student veterans' input to ensure that supports meet their needs.

Mental Health Needs of Aging Veterans: Recent Evidence and Clinical Recommendations

Objectives: Large numbers of older Americans have a history of military service, which may be positively or negatively associated with mental health in late life. We reviewed literature with the aim of better understanding the mental health needs of older Veterans.Methods: Articles included those published in 2009-2018 and focused on prevalence/risk for mental illness and suicide among older Veterans; utilization of mental health services; effectiveness of evidence-based behavioral treatments; and pertinent care delivery models.Results: Older Veterans are generally resilient. A significant minority experience mental health concerns that are associated with poor outcomes including a substantial number of suicides. Most published research is based on the approximately one third of Veterans who use the Veterans Health Administration (VHA) for care. Older Veterans with mental health diagnoses are less likely to utilize mental health services compared to younger Veterans, but as likely to benefit once engaged. Integrated care models in primary and geriatric care settings are promising.Conclusions: Aging Veterans are a large subset of Americans whose mental health needs are complex and deserve attention.Clinical Implications: Clinicians should ask about history of military service (i.e., Veteran status) and utilize available resources when providing care for older Veterans.

Coping Strategies and Workplace Supports for Peers with Substance Use Disorders

Introduction: Substance use disorder (SUD) peers provide support and navigation through a fragmented treatment system for people who use drugs (PWUD) and those in recovery. While barriers to peers' work are well established, from role ambiguity to stigma surrounding substance use, little research has focused on factors that facilitate peers' work. Methods: We conducted in-depth semi-structured interviews (N=20) with peers as part of an evaluation of a larger project related to the opioid crisis in Western New York. Participants were recruited from a regional peer network via flyers, emails, and a brief presentation. Interviews were conducted in person or by phone, audio recorded, and transcribed. Transcripts were analyzed using thematic content analysis. Results: Peers emphasized two factors: healthy personal coping strategies and strong workplace supports. Coping strategies included a sense of community, setting appropriate boundaries, and self-care routines. At the workplace, peers valued mental and emotional support, as well as professional relationships and organizational policies that made their work easier and supported self-care. For a few peers, professional relationships included advocating on behalf of PWUD by sharing personal experiences of SUD. Conclusions: Peers valued peer colleagues and peer-led organizations, noting how shared experiences of substance use and recovery enabled a unique support system. For peers who lack such support at work, the authors suggest peer networks as an alternative. We also recommend organizational policies and practices to facilitate peers' work, such as promoting peer input and feedback, but further research is needed to measure effects on peer retention and job satisfaction.

Impact of COVID-19 on Screening Rates for Colorectal, Breast, and Cervical Cancer: Practice Feedback From a Quality Improvement Project in Primary Care

PURPOSE

Three New York State practice-based research networks provided quality improvement strategies to improve screening rates for breast, cervical, and colorectal (BCC) cancers in safety-net primary care, over 7 years. In the final year (Y7), the United States experienced the COVID-19 pandemic. The impact of the COVID-19 pandemic on BCC cancer screening rates was assessed qualitatively.

METHODS

A total of 12 primary care practices participated in Y7 of the quality improvement project. BCC cancer screening rates at year beginning and end were assessed. Practice staff were asked about how COVID-19 impacted screening. Average pre/postintervention screening rates and qualitative thematic analysis regarding how COVID-19 impacted cancer screening were ascertained.

RESULTS

In Y7, there was an increase in breast cancer and a decrease in colorectal and cervical cancer screening rates compared to the previous project year. Many practices were able to continue pre-COVID-19 cancer screening processes. Overall, practices reported loss of staff, changes in data entry, and a shift from preventive screening to care of sick patients. Telehealth was vital for practices to continue serving patients but had a less positive impact on patients with financial/technological disadvantages. BCC cancer screenings were impacted at various levels.

CONCLUSIONS

The COVID-19 pandemic negatively impacted primary care practice cancer screening; however, some practices were able to mitigate effects by shifting focus to processes supporting screening outside of in-person office visits.

Increasing Breast, Cervical, and Colorectal Cancer Screenings: A Qualitative Assessment of Barriers and Promoters in Safety-Net Practices

PURPOSE

Breast, cervical, and colorectal cancer screening rates are suboptimal in underserved populations. A 7-year quality improvement (QI) project implemented academic detailing and practice facilitation in safety-net primary care practices to increase cancer screening rates. This manuscript assesses barriers and promoters.

METHODS

Primary care practices providing care to underserved patients were recruited in New York cities Buffalo, Rochester, and Syracuse. Enrollment totaled 31 practices, with 12 practices participating throughout. Annually, each practice received 6 months of practice facilitation support for development and implementation of evidence-based interventions to increase screening rates for the three cancer types. At the end of each practice facilitation period, focus groups and key informant interviews were conducted with participating personnel. Content analysis was performed annually to identify barriers and promoters. A comprehensive final analysis was performed at project end.

RESULTS

Barriers included system-level (inconsistent communication with specialists, electronic health record system transitions, ownership changes) and practice-level challenges (staff turnover, inconsistent data entry, QI fatigue) that compound patient-level challenges of transportation, cost, and health literacy. Cyclical barriers like staff turnover returned despite attempts to resolve them, while successful implementation was promoted by reducing patients' structural barriers, adapting interventions to existing practice priorities, and enacting officewide policies. During the QI project, practices became aware of the impact of social determinants of health on patients' screening decisions.

CONCLUSIONS

The project's longitudinal design enabled identification of key barriers that reduced accuracy of practices' screening rates and increased risk of patients falling through the cracks. Identified promoters can help sustain interventions to increase screenings.

Improving Cancer Screening Rates in Primary Care via Practice Facilitation and Academic Detailing: A Multi-PBRN Quality Improvement Project

PURPOSE

In the United States, cancer screening rates are often below national targets. This project implemented practice facilitation and academic detailing aimed at increasing breast, cervical, and colorectal cancer screening rates in safety-net primary care practices.

METHODS

Three practice-based research networks across western and central New York State partnered to provide quality improvement strategies on breast, cervical, and colorectal cancer screening. Pre/postintervention screening rates for all participating practices were collected annually, as were means across all practices over 7 years. Simple ordinary least squares linear regression was used to calculate the trend for each cancer type and test for statistical significance (ie, P≤0.05), using the ordinal time point as a fixed effect.

RESULTS

An overall increase in mean screening rates was seen over the duration of this project for colorectal (24.6% preintervention to 48.0% in year 7 of intervention; P<0.001) and breast cancer (37.0% preintervention to 48.6% in year 7; P=0.460). Mean cervical cancer screening rates decreased (35.5% preintervention to 31.4% in year 7; P=0.209). Success in increasing screening rates varied across regions of New York State.

CONCLUSIONS

Practice facilitation and academic detailing were successful in significantly increasing, on average, colorectal cancer screening rate. Cervical cancer screening showed an overall decrease, likely due to difficulties for primary care practices in tracking and implementation, as many patients seek this service at outside gynecology facilities. Regional differences, guideline changes, and practice reorganization each may have played a part in observed trends. A standardization of queries being used to pull screening rates is an important step in increasing the reliability of these data.

Variations in Risk and Motivations for Substance Use over the Course of Military Service

Epidemiological data identify risk factors related to substance use among military service members to inform prevention and treatment. Less is known about how motivations and risks for substance use vary over a military service career. The study goal was to explore substance use patterns and motivations among a sample of United States undergraduate student veterans in order to identify periods of risk. Methods: Qualitative interviews were conducted (n = 31) between December 2018 and April 2019. Transcripts were coded in ATLAS.ti using thematic content analysis. Results: Interviews revealed complex motivations around substance use and identified key periods of risk. 1) Pre-service: Participants reported using alcohol and marijuana, primarily during social activities. 2) During service: Participants described a culture of heavy alcohol and tobacco use in social contexts, but little use of other substances. Post-deployment was a notable exception, when some reported heavier alcohol use and use of other drugs, including opiates, cocaine, and ecstasy. 3) Post-service: Transitioning out of the military was described as difficult; some participants reported heavier use of substances during this period. Some participants quit smoking after military service, or switched to vaping. Others reported use of alcohol and/or marijuana to calm themselves, relieve stress, and enable sleep. Conclusions: These data indicate that the periods immediately following deployment and transition out of the military may be especially high-risk for heavy substance use and use of a broader range of substances. This highlights the need for tailored interventions and messaging at different points of military service, particularly during periods of greatest risk.

Primary care and mental health providers' perceptions of implementation of pharmacogenetics testing for depression prescribing

BACKGROUND

Pharmacogenetic testing (PGx) has the potential to improve the quality of psychiatric prescribing by considering patients' genetic profile. However, there is limited scientific evidence supporting its efficacy or guiding its implementation. The Precision Medicine in Mental Health (PRIME) Care study is a pragmatic randomized controlled trial evaluating the effectiveness of a specific commercially-available pharmacogenetic (PGx) test to inform antidepressant prescribing at 22 sites across the U.S. Simultaneous implementation science methods using the Consolidated Framework for Implementation Research (CFIR) are integrated throughout the trial to identify contextual factors likely to be important in future implementation of PGx. The goal of this study was to understand providers' perceptions of PGx for antidepressant prescribing and implications for future implementation.

METHODS

Qualitative focus groups (n = 10) were conducted at the beginning of the trial with Primary Care and Mental Health providers (n = 31) from six PRIME Care sites. Focus groups were audio-recorded and transcribed and data were analyzed using rapid analytic procedures organized by CFIR domains.

RESULTS

Analysis revealed themes in the CFIR Intervention Characteristics domain constructs of Evidence, Relative Advantage, Adaptability, Trialability, Complexity, and Design that are important for understanding providers' perceptions of PGx testing. Results indicate: 1) providers had limited experience and knowledge of PGx testing and its evidence base, particularly for psychiatric medications; 2) providers were hopeful that PGx could increase their precision in depression prescribing and improve patient engagement, but were uncertain about how results would influence treatment; 3) providers were concerned about potential misinterpretation of PGx results and how to incorporate testing into their workflow; 4) primary care providers were less familiar and comfortable with application of PGx testing to antidepressant prescribing than psychiatric providers.

CONCLUSIONS

Provider perceptions may serve as facilitators or barriers to implementation of PGx for psychiatric prescribing. Incorporating implementation science into the conduct of the RCT adds value by uncovering factors to be addressed in preparing for future implementation, should the practice prove effective.

Opportunities and Recommendations for Improving Medication Safety: Understanding the Medication Management System in Primary Care Through an Abstraction Hierarchy

Background

Despite making great strides in improving the treatment of diseases, the minimization of unintended harm by medication therapy continues to be a major hurdle facing the health care system. Medication error and prescription of potentially inappropriate medications (PIMs) represent a prevalent source of harm to patients and are associated with increased rates of adverse events, hospitalizations, and increased health care costs. Attempts to improve medication management systems in primary care have had mixed results. Implementation of new interventions is difficult because of complex contextual factors within the health care system. Abstraction hierarchy (AH), the first step in cognitive work analysis (CWA), is used by human factors practitioners to describe complex sociotechnical systems. Although initially intended for the nuclear power domain and interface design, AH has been used successfully to aid the redesign of numerous health care systems such as the design of decision support tools, mobile patient monitoring apps, and a telephone triage system.

Objective

This paper aims to refine our understanding of the primary care office in relation to a patient’s medication through the development of an AH. Emphasis was placed on the elements related to medication safety to provide guidance for the design of a safer medication management system in primary care.

Methods

The AH development was guided by the methodology used by seminal CWA literature. It was initially developed by 2 authors and later fine-tuned by an expert panel of clinicians, social scientists, and a human factors engineer. It was subsequently refined until an agreement was reached. A means-ends analysis was performed and described for the nodes of interest. The model represents the primary care office space through functional purposes, values and priorities, function-related purposes, object-related processes, and physical objects.

Results

This model depicts the medication management system at various levels of abstraction. The resulting components must be balanced and coordinated to provide medical treatment with limited health care resources. Understanding the physical and informational constraints on activities that occur in a primary care office depicted in the AH defines areas in which medication safety can be improved.

Conclusions

Numerous means-ends relationships were identified and analyzed. These can be further evaluated depending on the specific needs of the user. Recommendations for optimizing a medication management system in a primary care facility were made. Individual practices can use AH for clinical redesign to improve prescribing and deprescribing practices.

Media coverage of managed care: is there a negative bias?

We conducted content analysis of media coverage (both print and broadcast) of managed care over the period 1 January 1990 to 30 June 1997, examining in detail more than 2,100 randomly selected stories. Coverage changed noticeably over the seven and a half-year period, with early years focused on managed care as a business story, and later years focused more on patient care and concerns about backlash. Coverage differed substantially depending on media source. The large majority of all media coverage of managed care was neutral in tone. However, the tone of coverage has become more critical over time and differs dramatically by source of media. The most visible media sources--television and newspaper special series--conveyed negative stories in more than half of their coverage and most often used anecdotes in telling their stories.

Hemodialysis and hemoperfusion for treatment of valproic acid and gabapentin poisoning

A 31-y-old epileptic man developed coma and shock after suicidally ingesting large amounts of valproic acid and gabapentin. His peak valproic acid, level was 1306.9 micrograms/mL (therapeutic range = 30-100 micrograms/mL). His peak gabapentin level was 60.0 micrograms/mL (therapeutic range = 2.0-8.0 micrograms/mL). His hypotension was refractory to crystalloid and pressor infusions, but resolved during concurrent hemoperfusion and hemodialysis to enhance elimination of valproic acid. Concurrent hemoperfusion and hemodialysis, in series, produced a maximum valproic acid plasma clearance of 55.4 mL/min versus a maximum reported intrinsic valproic acid plasma clearance of 10.6 mL/min. concurrent hemoperfusion and hemodialysis, in series, should be considered in hemodynamically unstable patients with valproic acid poisoning whose clinical condition is worsening in spite of aggressive supportive care.

The relationship between interferon-gamma and keratinocyte alloantigen expression after burn injury

BACKGROUND

Cultured keratinocyte (CK) and cadaveric skin allografts have prolonged survival in patients with massive thermal injury. It is unclear if this delayed rejection is due to impaired host responsiveness or decreased graft immunogenicity. Although burn injury has been shown to decrease parameters of allograft response, no studies have examined the effect of burn injury on alloantigen expression. This study investigated the effect of burn size on class II antigen expression in CK allografts as well as on tissue levels of interferon-gamma (IFN-gamma), the principle regulator of alloantigen expression.

METHODS

Anesthetized CBA mice (n = 64) received a 0%, 20% partial-thickness (PT), 20% full-thickness (FT), or 40% FT contact burn. Forty-eight hours later, wounds were partially excised and covered with CK allografts from C57BL/6 donors. Five days after burn injury, grafts were analyzed for donor-specific class II antigen. Protein expression was determined by Western immunoblotting and quantified with video densitometry. Wound, serum, and unburned skin levels of IFN-gamma were determined by enzyme-linked immunosorbent assay. Groups were compared by Fisher's analysis of variance.

RESULTS

As burn size increased, class II antigen expression decreased (p < 0.001). This corresponded with decreased wound and skin levels of IFN-gamma after 40% burn (p < 0.05); however, wound IFN-gamma was significantly elevated after 20% PT and FT burns (p < 0.01). Serum IFN-gamma increased as burn size increased (p < 0.01).

CONCLUSIONS

Burn injury decreases the antigenicity of CK allografts, which partly explains delayed allograft rejection after burn injury. Although wound IFN-gamma increases after minor thermal injury, the profound decrease in wound and skin IFN-gamma after a major burn corresponds with diminished class II antigen expression. The decreased availability of IFN-gamma after major thermal injury provides a mechanism for limited allograft tolerance.

Xenogeneic mouse fibroblasts persist in human cultured epidermal grafts: a possible mechanism of graft loss

Recent reports suggest that long-term graft take of cultured epidermal autografts (CEAs) is less than 50% when late graft loss is considered. The characteristics of late CEA loss suggest that it may occur as a result of an immunologic reaction to persistent xenogeneic cells and/or proteins used to grow CEA. In this study we examined whether immunologically reactive, mouse 3T3 fibroblasts used as feeder layers can persist in primary, secondary, and tertiary human CEA. We cocultured keratinocytes from 11 separate burn patients with growth-arrested 3T3 fibroblasts. After removing visible 3T3 fibroblasts from CEA with trypsinization, we allowed CEA to reach confluence. We then harvested CEA either as primary, secondary, or tertiary cultures. We detected mouse fibroblasts using fluorescence activated cell sorting (FACS) with a monoclonal antibody specific for mouse major histocompatibility (MHC) antigens. We detected mouse MHC class II antigens by performing Western immunoblotting with another mouse MHC-specific monoclonal antibody. By FACS we identified mouse fibroblasts in 100, 75, and 62.5% of primary, secondary, and tertiary passage CEAs, respectively. Similarly by immunoblotting we found mouse MHC class II antigen in 100, 80, and 66.7% of primary, secondary, and tertiary CEAs. These results demonstrate that xenogeneic fibroblast feeder layers capable of generating immunogenic transplantation antigens persist in CEAs. The persistence of these cells and their antigen expression may contribute to CEA loss.
