Overcoming barriers to implementation: mapping implementation strategies in four hospital in home programs within the Veterans Health Administration. Home Health Care Serv Q 2024:1-18. [PMID: 38174378 DOI: 10.1080/01621424.2023.2301413] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/05/2024]
Abstract
The Hospital at Home model, called Hospital-in-Home (HIH) in the Department of Veterans Affairs, delivers coordinated, high-value care aligned with older adult and caregiver preferences. Documenting implementation barriers and corresponding strategies to overcome them can address challenges to widespread adoption. To evaluate HIH implementation barriers and identify strategies to address them, we conducted interviews with 8 HIH staff at 4 hospitals between 2010 and 2013. We utilized qualitative directed content analysis guided by the Consolidated Framework for Implementation Research (CFIR) and mapped identified barriers to possible strategies using the CFIR-Expert Recommendations for Implementing Change (ERIC) Matching Tool. We identified 11 barriers spanning 5 CFIR domains. Three implementation strategies - identifying and preparing champions, conducting educational meetings, and capturing and sharing local knowledge - achieved high expert endorsement for each barrier. A mix of strategies targeting resources, organizational readiness and fit, and leadership engagement should be considered to support the sustainability and spread of HIH.

Measuring Patient-Reported Use and Outcomes From Complementary and Integrative Health Therapies: Development of the Complementary and Integrative Health Therapy Patient Experience Survey. GLOBAL ADVANCES IN INTEGRATIVE MEDICINE AND HEALTH 2024; 13:27536130241241259. [PMID: 38585239 PMCID: PMC10998493 DOI: 10.1177/27536130241241259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 02/06/2024] [Accepted: 03/04/2024] [Indexed: 04/09/2024]
Abstract
Background Assessing the use and effectiveness of complementary and integrative health (CIH) therapies via survey can be complicated given CIH therapies are used in various locations and formats, the dosing required to have an effect is unclear, the potential health and well-being outcomes are many, and describing CIH therapies can be challenging. Few surveys assessing CIH therapy use and effectiveness exist, and none sufficiently reflect these complexities. Objective In a large-scale Veterans Health Administration (VA) quality improvement effort, we developed the "Complementary and Integrative Health Therapy Patient Experience Survey", a longitudinal, electronic patient self-administered survey to comprehensively assess CIH therapy use and outcomes. Methods We obtained guidance from the literature, subject matter experts, and Veteran patients who used CIH therapies in designing the survey. As a validity check, we completed cognitive testing and interviews with those patients. We conducted the survey (March 2021-April 2023), inviting 15,608 Veterans with chronic musculoskeletal pain with a recent CIH appointment or referral identified in VA electronic medical records (EMR) to participate. As a second validity check, we compared VA EMR data and patient self-reports of CIH therapy utilization a month after survey initiation and again at survey conclusion. Results The 64-item, electronic survey assesses CIH dosing (amount and timing), delivery format and location, provider location, and payor. It also assesses 7 patient-reported outcomes (pain, global mental health, global physical health, depression, quality of life, stress, and meaning/purpose in life), and 3 potential mediators (perceived health competency, healthcare engagement, and self-efficacy for managing diseases). The survey took 17 minutes on average to complete and had a baseline response rate of 45.3%. We found high degrees of concordance between self-reported and EMR data for all therapies except meditation. Conclusions Validly assessing patient-reported CIH therapy use and outcomes is complex, but possible.

A Novel Informatics Tool to Detect Periprocedural Antibiotic Allergy Adverse Events for Near Real-time Surveillance to Support Audit and Feedback. JAMA Netw Open 2023; 6:e2313964. [PMID: 37195660 PMCID: PMC10193175 DOI: 10.1001/jamanetworkopen.2023.13964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 03/31/2023] [Indexed: 05/18/2023] Open
Abstract
Importance Standardized processes for identifying when allergic-type reactions occur and linking reactions to drug exposures are limited. Objective To develop an informatics tool to improve detection of antibiotic allergic-type events. Design, Setting, and Participants This retrospective cohort study was conducted from October 1, 2015, to September 30, 2019, with data analyzed between July 1, 2021, and January 31, 2022. The study was conducted across Veteran Affairs hospitals among patients who underwent cardiovascular implantable electronic device (CIED) procedures and received periprocedural antibiotic prophylaxis. The cohort was split into training and test cohorts, and cases were manually reviewed to determine presence of allergic-type reaction and its severity. Variables potentially indicative of allergic-type reactions were selected a priori and included allergies entered in the Veteran Affair's Allergy Reaction Tracking (ART) system (either historical [reported] or observed), allergy diagnosis codes, medications administered to treat allergic reactions, and text searches of clinical notes for keywords and phrases indicative of a potential allergic-type reaction. A model to detect allergic-type reaction events was iteratively developed on the training cohort and then applied to the test cohort. Algorithm test characteristics were assessed. Exposure Preprocedural and postprocedural prophylactic antibiotic administration. Main Outcomes and Measures Antibiotic allergic-type reactions. Results The cohort of 36 344 patients included 34 703 CIED procedures with antibiotic exposures (mean [SD] age, 72 [10] years; 34 008 [98%] male patients); median duration of postprocedural prophylaxis was 4 days (IQR, 2-7 days; maximum, 45 days). The final algorithm included 7 variables: entries in the Veteran Affair's hospitals ART, either historic (odds ratio [OR], 42.37; 95% CI, 11.33-158.43) or observed (OR, 175.10; 95% CI, 44.84-683.76); PheCodes for "symptoms affecting skin" (OR, 8.49; 95% CI, 1.90-37.82), "urticaria" (OR, 7.01; 95% CI, 1.76-27.89), and "allergy or adverse event to an antibiotic" (OR, 11.84, 95% CI, 2.88-48.69); keyword detection in clinical notes (OR, 3.21; 95% CI, 1.27-8.08); and antihistamine administration alone or in combination (OR, 6.51; 95% CI, 1.90-22.30). In the final model, antibiotic allergic-type reactions were identified with an estimated probability of 30% or more; positive predictive value was 61% (95% CI, 45%-76%); and sensitivity was 87% (95% CI, 70%-96%). Conclusions and Relevance In this retrospective cohort study of patients receiving periprocedural antibiotic prophylaxis, an algorithm with a high sensitivity to detect incident antibiotic allergic-type reactions that can be used to provide clinician feedback about antibiotic harms from unnecessarily prolonged antibiotic exposures was developed.

Abstract
OBJECTIVE To understand what factors and organizational dynamics enable Lean transformation of health care organizations. DATA SOURCES Primary data were collected through two waves of interviews in 2016-2017 with leaders and staff at seven veterans affairs medical centers participating in Lean enterprise transformation. STUDY DESIGN Using an observational study design, for each site we coded and rated seven potential enablers of transformation. The outcome measure was the extent of Lean transformation, constructed by coding and rating 11 markers of depth and spread of transformation. Using multivalue coincidence analysis (CNA), we identified enablers that distinguished among sites having different levels of transformation. We identified representative quotes for the enablers. DATA COLLECTION METHODS We interviewed 121 executive leaders, middle managers, expert consultants, systems redesign staff, frontline supervisors, and staff. PRINCIPAL FINDINGS Two sites achieved high Lean transformation, three medium, and two low. Together leadership support and capability development were sufficient for the three-level Lean transformation outcomes with 100% consistency and 100% coverage. High scores on both corresponded to high Lean transformation; medium on either one corresponded to medium transformation; and low on both corresponded to low transformation. Additionally, low scores in communication and availability of data and very low scores in alignment characterized low-transformation sites. Sites with high leadership support also had a high veteran engagement. CONCLUSIONS This multisite study develops a novel measure of the extent of organization-wide Lean transformation and uses CNA to identify enablers linked to transformation. It provides insights into why and how some organizations are more successful at transformation than others. Findings support the applicability of the organization transformation model that guided the study and highlight the roles of executive leadership and capability development in the dynamics of transformation.

Identification of Implementation Strategies Using the CFIR-ERIC Matching Tool to Mitigate Barriers in a Primary Care Model for Older Veterans. THE GERONTOLOGIST 2023; 63:439-450. [PMID: 36239054 DOI: 10.1093/geront/gnac157] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND AND OBJECTIVES As the proportion of the U.S. population over 65 and living with complex chronic conditions grows, understanding how to strengthen the implementation of age-sensitive primary care models for older adults, such as the Veterans Health Administration's Geriatric Patient-Aligned Care Teams (GeriPACT), is critical. However, little is known about which implementation strategies can best help to mitigate barriers to adopting these models. We aimed to identify barriers to GeriPACT implementation and strategies to address these barriers using the Consolidated Framework for Implementation Research-Expert Recommendations for Implementing Change (CFIR-ERIC) Matching Tool. RESEARCH DESIGN AND METHODS We conducted a content analysis of qualitative responses obtained from a web-based survey sent to GeriPACT members. Using a matrix approach, we grouped similar responses into key barrier categories. After mapping barriers to CFIR, we used the Tool to identify recommended strategies. RESULTS Across 53 Veterans Health Administration hospitals, 32% of team members (n = 197) responded to our open-ended question about barriers to GeriPACT care. Barriers identified include Available Resources, Networks & Communication, Design Quality & Packaging, Knowledge & Beliefs, Leadership Engagement, and Relative Priority. The Tool recommended 12 Level 1 (e.g., conduct educational meetings) and 24 Level 2 ERIC strategies (e.g., facilitation). Several strategies (e.g., conduct local consensus discussions) cut across multiple barriers. DISCUSSION AND IMPLICATIONS Strategies identified by the Tool can inform on-going development of the GeriPACT model's effective implementation and sustainment. Incorporating cross-cutting implementation strategies that mitigate multiple barriers at once may further support these next steps.

A Citation Review of 83 Dissemination and Implementation Theories, Models, or Frameworks Utilized in U.S.-Based Aging Research. THE GERONTOLOGIST 2023; 63:405-415. [PMID: 35797202 DOI: 10.1093/geront/gnac096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Dissemination-implementation.org outlines 110 theories, models, and frameworks (TMFs): we conducted a citation analysis on 83 TMFs, searching Web of Science and PubMed databases. RESEARCH DESIGN AND METHODS Search terms were broad and included "aging," "older," "elderly," and "geriatric." We extracted each TMF in identified articles from inception through January 28, 2022. Included articles must have used a TMF in research or quality improvement work directly linked to older adults within the United States. RESULTS We reviewed 2,681 articles of which 295 articles cited at least one of 56 TMFs. Five TMFs represented 50% of the citations: Reach, Effectiveness, Adoption, Implementation, and Maintenance 1.0, Consolidated Framework for Implementation Research, Greenhalgh Diffusion of Innovation in Service Organizations, Quality Enhancement Research Initiative, Community-Based Participatory Research, and Promoting Action on Research Implementation in Health Services. TMF application varied and there was a steady increase in TMF citations over time, with a 2- to 3-fold increase in citations in 2020-2021. We identified that only 41% of TMF use was meaningful. DISCUSSION AND IMPLICATIONS Our results suggest TMF utilization is increasing in aging research, but there is a need to more meaningful utilize TMFs. As the population of older adults continues to grow, there will be increasing demand for effective evidence-based practices and models of care to be quickly and effectively translated into routine care. Use of TMFs is critical to building such evidence and to identifying and evaluating methods to support this translation.

Poor insight and future thinking in early dementia limit patient projections of potential utility of technological innovations and advanced care planning. Front Med (Lausanne) 2023; 10:1123331. [PMID: 36993808 PMCID: PMC10040527 DOI: 10.3389/fmed.2023.1123331] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Accepted: 02/13/2023] [Indexed: 03/14/2023] Open
Abstract
IntroductionCognitive psychology posits that thinking about the future relies on memory such that those with memory impairment may have trouble imaging their future technology and other needs.MethodsWe conducted a content analysis of qualitative data from interviews with six patients with MCI or early dementia regarding potential adaptations to a mobile telepresence robot. Using a matrix analysis approach, we explored perceptions of (1) what technology could help with day-to-day functioning in the present and future and (2) what technology may help people with memory problems or dementia stay home alone safely.ResultsVery few participants could identify any technology to assist themselves or other people with memory problems and could not provide suggestions on what technology may help them stay home alone safely. Most perceived that they would never need robotic assistance.DiscussionThese findings suggest individuals with MCI or early dementia have limited perspectives on their own functional abilities now and in the future. Consideration of the individuals’ diminished understanding of their own future illness trajectory is crucial when engaging in research or considering novel technological management solutions and may have implications for other aspects of advanced care planning.

Prevalence of One-Year Mortality after Implantable Cardioverter Defibrillator Placement: An Opportunity for Palliative Care? J Palliat Med 2023; 26:175-181. [PMID: 36067080 PMCID: PMC9894597 DOI: 10.1089/jpm.2022.0205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/18/2022] [Indexed: 02/05/2023] Open
Abstract
Background: Current guidelines recommend against placement of implantable cardioverter defibrillators in patients with a life expectancy less than one year. These patients may benefit from early palliative care services; however, identifying this population is challenging. Objective: Determine whether a validated prognostic tool, based on patient factors and health care utilization from electronic medical records, accurately predicts one-year mortality at the time of implantable cardioverter defibrillator placement. Design: We used the United States (U.S.) Veterans Administration's "Care Assessment Needs" one-Year Mortality Score to identify patients at high risk of mortality (score ≥95) before their procedure. Data were extracted from the Corporate Data Warehouse. Logistic regression was used to assess the odds of mortality at different score levels. Setting/Subjects: Patients undergoing a new implantable cardioverter defibrillator procedure between October 1, 2015 and September 30, 2017 in the U.S. Veterans Administration. Results: Of 3194 patients with a new implantable cardioverter defibrillator placed, 657 (21.8%) had a score ≥95. The mortality rate among these patients was 151/657 (22.9%) compared with 281/3194 (8.8%) for all patients undergoing a new implantable cardioverter defibrillator procedure. Patients with a score ≥95 had 14.0 (95% confidence interval 8.0-24.4) higher odds of death within one year of the procedure compared with those with a score ≤60. Conclusions: The "Care Assessment Needs" Score is a valid predictor of one-year mortality following implantable cardioverter defibrillator procedures. Integrating its use into the management of Veterans Administration (VA) patients considering implantable cardioverter defibrillators may improve shared decision making and engagement with palliative care.

Abstract
Background and objectives The Department of Veterans Affairs (VA) Hospital-In-Home (HIH) program delivers patient-centered, acute-level hospital care at home. Compared to inpatient care, HIH has demonstrated improved patient safety, effectiveness, and patient and caregiver satisfaction. The VA Office of Geriatrics & Extended Care (GEC) has supported the development of 12 HIH program sites nationally, yet adoption in VA remains modest, and questions remain regarding optimal implementation practices to extend reach and adaptability of this innovation. Guided by theoretical and procedural implementation science frameworks, this study aims to systematically gather evidence from the 12 HIH programs and to develop a participatory approach to engage stakeholders, assess readiness, and develop/adapt implementation strategies and evaluation metrics. Research design and methods We propose a multi-phase concurrent triangulation design comprising of (1) qualitative interviews with key informants and document review, (2) quantitative evaluation of effectiveness outcomes, and (3) mixed-methods synthesis and adaptation of a Reach Effectiveness Adoption Implementation Maintenance (RE-AIM)-guided conceptual framework. Results The prospective phase will involve a participatory process of identifying stakeholders (leadership, HIH staff, veterans, and caregivers), engaging in planning meetings informed by implementation mapping, and developing implementation logic models and blueprints. The process will be assessed using a mixed-methods approach through participant observation and document review. Discussion and implication This study will support the continued spread of HIH programs, generate a catalog of HIH implementation evidence, and create implementation tools and infrastructure for future HIH development. The multi-phase nature of informing prospective planning with retrospective analysis is consistent with the Learning Health System framework.

Abstract
The Veterans Health Administration (VA) provides services to growing numbers of Veterans with dementIa, individuals at heightened risk for hospitalizations and nursing home placement. Beginning in 2010, the VA funded 12 innovative pilot programs to improve dementia care and help Veterans remain at home. We conducted a retrospective qualitative analysis of program materials and interviews with physicians, nurses, social workers, and other personnel (n = 33) to understand the strategies these programs adopted. Interviews were conducted every 6 months between 2010-2013 (4-5 interviews per program) and focused on factors affecting program design and implementation, challenges, and strategies to reduce hospitalizations and nursing home placements. Programs varied considerably yet shared three overarching strategies to improve dementia care: involving and supporting family caregivers; engaging interdisciplinary teams; and improving coordination with other healthcare providers. Our results highlight the importance of adapting common dementia care strategies based on the local context and needs of individuals served.

Factors Affecting Primary Care Implementation for Older Veterans with multimorbidity in VA. Health Serv Res 2021; 56 Suppl 1:1057-1068. [PMID: 34363207 DOI: 10.1111/1475-6773.13859] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 06/30/2021] [Accepted: 07/02/2021] [Indexed: 11/28/2022] Open
Abstract
OBJECTIVE To identify factors affecting implementation of Geriatric Patient Aligned Care Teams (GeriPACT), a patient-centered medical home model for older adults with complex care needs including multiple chronic conditions (MCC), designed to provide them with comprehensive, managed and coordinated primary care. DATA SOURCES Qualitative data was collected from key informants at eight VA Medical Centers (VAMCs) geographically spread across the US. STUDY DESIGN Guided by the Consolidated Framework for Implementation Research (CFIR), we collected prospective primary data through semi-structured interviews with GeriPACT team members (e.g. physicians, nurses, social workers, pharmacists), leaders (e.g., executive leaders and middle managers), and other staff referring to the program. DATA COLLECTION We conducted in-person, semi-structured interviews with 134 key informants. Interviews were recorded with permission and professionally transcribed. Transcripts were coded in NVIVO 11. We used directed content analysis to identify key factors affecting GeriPACT implementation across sites. PRINCIPAL FINDINGS Five key factors affected GeriPACT implementation-5 CFIR constructs within two CFIR domains. Within the intervention characteristics domain, two constructs emerged: 1) the structure of the GeriPACT model, and 2) design, quality and packaging. In the inner setting domain, we identified three constructs: 1) available resources (e.g., staffing and space, and infrastructure and information technology; 2) leadership support and engagement, and 3) networks and communications including teamwork, communication and coordination. CONCLUSIONS Older Veterans with MCC have complex primary care needs requiring high levels of care management and coordination. Knowing what key factors affect GeriPACT implementation is critical. Study findings also contribute to the growing implementation science literature on applying CFIR to evaluate factors that affect program implementation, especially to aging research. Further studies on MCC-focused specialty primary care will help facilitate patient-centered care provision for older adults' complex health needs while also leveraging synergistic work across factors affecting implementation.

Abstract
Background By 2050, nearly 13 million Americans will have Alzheimer disease and related dementias (ADRD), with most of those with ADRD or mild cognitive impairment (MCI) receiving home care. Mobile telepresence robots may allow persons with MCI or ADRD to remain living independently at home and ease the burden of caregiving. The goal of this study was to identify how an existing mobile telepresence robot can be enhanced to support at-home care of people with MCI or ADRD through key stakeholder input. Objective The specific aims were to assess what applications should be integrated into the robot to further support the independence of individuals with MCI or ADRD and understand stakeholders’ overall opinions about the robot. Methods We conducted in-person interviews with 21 stakeholders, including 6 people aged >50 years with MCI or ADRD living in the community, 9 family caregivers of people with MCI or ADRD, and 6 clinicians who work with the ADRD population. Interview questions about the robot focused on technology use, design and functionality, future applications to incorporate, and overall opinions. We conducted a thematic analysis of the data obtained and assessed the patterns within and across stakeholder groups using a matrix analysis technique. Results Overall, most stakeholders across groups felt positively about the robot’s ability to support individuals with MCI or ADRD and decrease caregiver burden. Most ADRD stakeholders felt that the greatest benefits would be receiving help in emergency cases and having fewer in-person visits to the doctor’s office. Caregivers and clinicians also noted that remote video communication with their family members using the robot was valuable. Adding voice commands and 1-touch lifesaving or help buttons to the robot were the top suggestions offered by the stakeholders. The 4 types of applications that were suggested included health-related alerts; reminders; smart-home–related applications; and social, entertainment, or well-being applications. Stakeholders across groups liked the robot’s mobility, size, interactive connection, and communication abilities. However, stakeholders raised concerns about their physical stability and size for individuals living in smaller, cluttered spaces; screen quality for those with visual impairments; and privacy or data security. Conclusions Although stakeholders generally expressed positive opinions about the robot, additional adaptations were suggested to strengthen functionality. Adding applications and making improvements to the design may help mitigate concerns and better support individuals with ADRD to live independently in the community. As the number of individuals living with ADRD in the United States increases, mobile telepresence robots are a promising way to support them and their caregivers. Engaging all 3 stakeholder groups in the development of these robots is a critical first step in ensuring that the technology matches their needs. Integrating the feedback obtained from our stakeholders and evaluating their effectiveness will be important next steps in adapting telepresence robots.

Abstract
OBJECTIVES The goal of this study was to examine psychosocial adjustment following transition from the nursing home (NH) to community and understand the ways in which adjustment intersects with social connection. METHODS We conducted interviews with community-dwelling older male Veterans after they were discharged from an NH. Interviews focused on Veterans' experience during the transition process. We utilized conventional content analysis to inductively code the interviews. We reviewed evidence in each identified domain for common themes. RESULTS We interviewed 13 NH residents after recent transitions from the NH back to the community. Four themes were identified: (1) access to and quality of social support network are important for social connection, (2) engagement in meaningful activities with family and friends improves well-being, (3) service providers form link to social connection, and (4) external stressors affect the quality of social connections. CONCLUSIONS Identified themes aligned with respondents' social connectedness and perceived psychosocial and physical well-being. Our results suggest that social connectedness is one part of the larger milieu of healthy aging including the importance of engagement with social opportunities and having a purpose. CLINICAL IMPLICATIONS Social connectedness is critical to assess for older adults transitioning between care settings. Developing screening tools and other interventions focused on social isolation are needed.

Abstract
BACKGROUND The NIH-DOD-VA Pain Management Collaboratory (PMC) supports 11 pragmatic clinical trials (PCTs) on nonpharmacological approaches to management of pain and co-occurring conditions in U.S. military and veteran health organizations. The Stakeholder Engagement Work Group is supported by a separately funded Coordinating Center and was formed with the goal of developing respectful and productive partnerships that will maximize the ability to generate trustworthy, internally valid findings directly relevant to veterans and military service members with pain, front-line primary care clinicians and health care teams, and health system leaders. The Stakeholder Engagement Work Group provides a forum to promote success of the PCTs in which principal investigators and/or their designees discuss various stakeholder engagement strategies, address challenges, and share experiences. Herein, we communicate features of meaningful stakeholder engagement in the design and implementation of pain management pragmatic trials, across the PMC. DESIGN Our collective experiences suggest that an optimal stakeholder-engaged research project involves understanding the following: i) Who are research stakeholders in PMC trials? ii) How do investigators ensure that stakeholders represent the interests of a study's target treatment population, including individuals from underrepresented groups?, and iii) How can sustained stakeholder relationships help overcome implementation challenges over the course of a PCT? SUMMARY Our experiences outline the role of stakeholders in pain research and may inform future pragmatic trial researchers regarding methods to engage stakeholders effectively.

Abstract
BACKGROUND Many health care systems are beginning to encourage patients to use complementary and integrative health (CIH) therapies for pain management. Many clinicians have anecdotally reported that patients combining self-care CIH therapies with practitioner-delivered therapies report larger health improvements than do patients using practitioner-delivered or self-care CIH therapies alone. However, we are unaware of any trials in this area. DESIGN The APPROACH Study (Assessing Pain, Patient-Reported Outcomes and Complementary and Integrative Health) assesses the value of veterans participating in practitioner-delivered CIH therapies alone or self-care CIH therapies alone compared with the combination of self-care and practitioner-delivered care. The study is being conducted in 18 Veterans Health Administration sites that received funding as part of the Comprehensive Addiction and Recovery Act to expand availability of CIH therapies. Practitioner-delivered therapies under study include chiropractic care, acupuncture, and therapeutic massage, and self-care therapies include tai chi/qi gong, yoga, and meditation. The primary outcome will be improvement on the Brief Pain Inventory 6 months after initiation of CIH as compared with baseline scores. Patients will enter treatment groups on the basis of the care they receive because randomizing patients to specific CIH therapies would require withholding therapies routinely offered at VA. We will address selection bias and confounding by using sites' variations in business practices and other encouragements to receive different types of CIH therapies as a surrogate for direct randomization by using instrumental variable econometrics methods. SUMMARY Real-world evidence about the value of combining self-care and practitioner-delivered CIH therapies from this pragmatic trial will help guide the VA and other health care systems in offering specific nonpharmacological approaches to manage patients' chronic pain.

Abstract
IMPORTANCE Health care-associated infections (HAIs) are preventable, harmful, and costly; however, few resources are dedicated to infection surveillance of nonsurgical procedures, particularly cardiovascular implantable electronic device (CIED) procedures. OBJECTIVE To develop a method that includes text mining of electronic clinical notes to reliably and efficiently measure HAIs for CIED procedures. DESIGN, SETTING, AND PARTICIPANTS In this multicenter, national cohort study using electronic medical record data for patients undergoing CIED procedures in Veterans Health Administration (VA) facilities for fiscal years (FYs) 2016 and 2017, an algorithm to flag cases with a true CIED-related infection based on structured (eg, microbiology orders, vital signs) and free text diagnostic and therapeutic data (eg, procedure notes, discharge summaries, microbiology results) was developed and validated. Procedure data were divided into development and validation data sets. Criterion validity (ie, positive predictive validity [PPV], sensitivity, and specificity) was assessed via criterion-standard manual medical record review. EXPOSURES CIED procedure. MAIN OUTCOMES AND MEASURES The concordance between medical record review and the study algorithm with respect to the presence or absence of a CIED infection. CIED infection in the algorithm included 90-day mortality, congestive heart failure and nonmetastatic tumor comorbidities, CIED or surgical site infection International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis codes, antibiotic treatment of Staphylococci, a microbiology test of a cardiac specimen, and text documentation of infection in specific clinical notes (eg, cardiology, infectious diseases, inpatient discharge summaries). RESULTS The algorithm sample consisted of 19 212 CIED procedures; 15 077 patients (78.5%) were White individuals, 1487 (15.5%) were African American; 18 766 (97.7%) were men. The mean (SD) age in our sample was 71.8 (10.6) years. The infection detection threshold of predicted probability was set to greater than 0.10 and the algorithm flagged 276 of 9606 (2.9%) cases in the development data set (9606 procedures); PPV in this group was 41.4% (95% CI, 31.6%-51.8%). In the validation set (9606 procedures), at predicted probability 0.10 or more the algorithm PPV was 43.5% (95% CI, 37.1%-50.2%), and overall sensitivity and specificity were 94.4% (95% CI, 88.2%-97.9%) and 48.8% (95% CI, 42.6%-55.1%), respectively. CONCLUSIONS AND RELEVANCE The findings of this study suggest that the method of combining structured and text data in VA electronic medical records can be used to expand infection surveillance beyond traditional boundaries to include outpatient and procedural areas.

Using the PACT Resources Framework to Understand the Needs of Geriatric Primary Care Teams. J Am Geriatr Soc 2020; 68:2006-2014. [PMID: 32379919 DOI: 10.1111/jgs.16498] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Revised: 03/20/2020] [Accepted: 04/03/2020] [Indexed: 11/28/2022]
Abstract
OBJECTIVES To identify the perceived organizational resources required by healthcare workers to deliver geriatric primary care in a geriatric patient aligned care team (GeriPACT). DESIGN Cross-sectional observational study using deductive analyses of qualitative interviews conducted with GeriPACT team members. SETTING GeriPACTs practicing at eight geographically dispersed Department of Veterans Affairs (VA) healthcare systems. PARTICIPANTS GeriPACT clinicians, nurses, clerical associates, clinical pharmacists, and social workers (n = 67). MEASUREMENTS Semistructured qualitative interviews conducted in person, transcribed, and then analyzed using the PACT Resources Framework. RESULTS Using the PACT Resources Framework, we identified facility-, clinic-, and team-level resources critical for GeriPACT implementation. Resources within each level reflect how the needs of older adults with complex comorbidity intersect with general population primary care medical home practice. GeriPACT implementation is facilitated by attention to patient characteristics such as cognitive impairment, ambulatory limitations, or social support services in staffing and resourcing teams. CONCLUSION Models of geriatric primary care such as GeriPACT must be implemented with an eye toward the most effective use of our most limited resource-trained geriatricians. In contrast to much of the literature on medical home teams serving a general adult population, interviews with GeriPACT members emphasize how patient needs inform all aspects of practice design including universal accessibility, near real-time response to patient needs, and ongoing interdisciplinary care coordination. Examination of GeriPACT implementation resources through the lens of traditional primary care teams illustrates the importance of tailoring primary care design to the needs of older adults with complex comorbidity.

Novel methodology to measure pre-procedure antimicrobial prophylaxis: integrating text searches with structured data from the Veterans Health Administration's electronic medical record. BMC Med Inform Decis Mak 2020; 20:15. [PMID: 32000780 PMCID: PMC6993312 DOI: 10.1186/s12911-020-1031-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Accepted: 01/20/2020] [Indexed: 11/11/2022] Open
Abstract
Background Antimicrobial prophylaxis is an evidence-proven strategy for reducing procedure-related infections; however, measuring this key quality metric typically requires manual review, due to the way antimicrobial prophylaxis is documented in the electronic medical record (EMR). Our objective was to electronically measure compliance with antimicrobial prophylaxis using both structured and unstructured data from the Veterans Health Administration (VA) EMR. We developed this methodology for cardiac device implantation procedures. Methods With clinician input and review of clinical guidelines, we developed a list of antimicrobial names recommended for the prevention of cardiac device infection. We trained the algorithm using existing fiscal year (FY) 2008–15 data from the VA Clinical Assessment Reporting and Tracking-Electrophysiology (CART-EP), which contains manually determined information about antimicrobial prophylaxis. We merged CART-EP data with EMR data and programmed statistical software to flag an antimicrobial orders or drug fills from structured data fields in the EMR and hits on text string searches of antimicrobial names documented in clinician’s notes. We iteratively tested combinations of these data elements to optimize an algorithm to accurately classify antimicrobial use. The final algorithm was validated in a national cohort of VA cardiac device procedures from FY2016–2017. Discordant cases underwent expert manual review to identify reasons for algorithm misclassification. Results The CART-EP dataset included 2102 procedures at 38 VA facilities with manually identified antimicrobial prophylaxis in 2056 cases (97.8%). The final algorithm combining structured EMR fields and text note search results correctly classified 2048 of the CART-EP cases (97.4%). In the validation sample, the algorithm measured compliance with antimicrobial prophylaxis in 16,606 of 18,903 cardiac device procedures (87.8%). Misclassification was due to EMR documentation issues, such as antimicrobial prophylaxis documented only in hand-written clinician notes in a format that cannot be electronically searched. Conclusions We developed a methodology with high accuracy to measure guideline concordant use of antimicrobial prophylaxis before cardiac device procedures using data fields present in modern EMRs. This method can replace manual review in quality measurement in the VA and other healthcare systems with EMRs; further, this method could be adapted to measure compliance in other procedural areas where antimicrobial prophylaxis is recommended.

Veterans Perceptions of Satisfaction and Convenience with Anticoagulants for Atrial Fibrillation: Warfarin versus Direct Oral Anticoagulants. Patient Prefer Adherence 2020; 14:1911-1922. [PMID: 33116435 PMCID: PMC7569027 DOI: 10.2147/ppa.s279621] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Accepted: 09/29/2020] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Atrial fibrillation (AFib) is associated with high morbidity and mortality. Traditionally, AFib was treated with warfarin, yet recent evidence suggests patients may favor direct oral anticoagulants (DOACs). Variation in preferences is common and we explored patients' perceptions of satisfaction and convenience of DOACs versus warfarin within the Veterans Health Administration (VA). PATIENTS AND METHODS We administered a cross-sectional survey, the Perception of Anticoagulant Treatment Questionnaire 2 (PACT-Q2), to Veterans residing in New England, age ≥65, diagnosed with AFib, and actively taking anticoagulant medication in fiscal year 2018. Survey recipients were randomly selected among patients on warfarin (n=200) or DOACs (n=200). A selection of survey respondents agreed to a follow-up semi-structured interview (n=16) to further investigate perceptions of satisfaction and convenience. RESULTS Of 400 patients, 187 completed the PACT-Q2 survey (49% on DOACs; 51% on warfarin). DOACs received significantly higher convenience ratings than warfarin (87.6, SD 13.5 vs 81.1, SD 18.8; p=0.007); there was no difference in satisfaction (64.2, SD 20.5 SD, warfarin vs, 67.3, SD 19.4, DOACs). Interview results showed that participants perceived their treatment to be convenient. However, participants expressed challenges related to the convenience of taking warfarin or DOACs, such as warfarin users having to follow dietary recommendations or DOAC users desiring some additional monitoring to answer questions or concerns. Overall, warfarin and DOAC users reported satisfaction with ongoing monitoring methods, although a few DOAC users expressed uncertainties with the frequency of monitoring. For most participants, concerns about side effects did not differ by anticoagulant type nor affect satisfaction. CONCLUSION Our survey and interview results showed variable patient satisfaction and perceptions of convenience with both DOACs and warfarin. Although DOACs are increasingly prescribed for AFib, some Veterans felt that regular follow-up on warfarin was advantageous. Our findings demonstrate the importance of patient-centered decision-making in AFib treatment in the VA patient population.

Abstract
Given the number of veterans who have experienced military sexual trauma (MST) and the impact of these experiences on veteran health, Veterans Health Administration (VHA) providers frequently communicate with patients about these experiences, either as part of the VHA's universal MST screening program or more comprehensive clinical care. The purpose of this study was to understand veterans' perceptions of communication related to MST disclosures with VHA providers. We conducted qualitative interviews, including a numeric rating question, with 55 veterans whose medical records indicated recent MST-related interactions with VHA providers. The sample included men and women, with and without histories of MST. We analyzed interview transcripts using matrices and identified themes related to satisfaction with communication. Veterans from all groups reported generally high satisfaction with MST-related communication, although men, as a group, reported a much larger range of satisfaction ratings than women. Key provider-related indicators of satisfaction included providers' communication mechanics and nonspecific patient-centered skills and characteristics. One patient-related indicator of lower satisfaction-inherent discomfort discussing MST experiences-was particularly represented among men with MST histories. These data from veteran patients will be reassuring to providers whose concerns about patient reactions to these conversations may inhibit them from raising this important issue. Understanding variables that promote patient satisfaction with MST disclosure communication is critical for promoting sensitive patient-provider interactions about MST. This ultimately can have important downstream effects on veteran health, allowing veterans to forge satisfying relationships with providers and ultimately facilitate recovery from traumatic experiences.

Predictive value of plasma neutrophil gelatinase-associated lipocalin in acute charcoal-burning carbon monoxide poisoning. Hum Exp Toxicol 2019; 38:877-887.

Abstract
This study aimed to assess the feasibility of using the plasma neutrophil gelatinase-associated lipocalin (NGAL) level at the time of presentation in the emergency department (ED) to predict acute kidney injury (AKI) and the long-term neurological outcomes of acute charcoal-burning carbon monoxide (CO) poisoning. This retrospective study included 260 patients who suffered acute charcoal-burning CO poisoning. The median plasma NGAL concentration at the time of presentation in the ED after acute charcoal-burning CO poisoning was 78 (54–115) ng/ml. The NGAL level was an independent predictor of AKI development and could be used to stratify the severity of AKI. However, the area under the receiver operating characteristic curve (AUC) of the predictive model for AKI that included both the plasma NGAL level and clinical parameters was comparable to that of the predictive model including only the clinical parameters. The plasma NGAL level at the time of presentation in the ED was an independent factor predicting long-term neurological outcomes in patients who did not develop AKI. In these patients, the plasma NGAL level significantly improved the predictive accuracy of the model when used in combination with clinical parameters. In contrast, the plasma NGAL level was not associated with long-term neurological outcomes in patients who developed AKI. Measurement of the plasma NGAL level at the time ED presentation might improve the prediction of long-term neurological outcomes in patients who do not develop AKI after acute charcoal-burning CO poisoning. However, it might not offer additional benefit for AKI prediction compared to previously used markers.

Abstract
This study investigated whether hyperthermia within the first 24 h after presentation was associated with long-term neurological outcomes after acute carbon monoxide (CO) poisoning. This retrospective study included 200 patients with acute severe CO poisoning. Hyperthermia (≥ 37.5°C) developed during the first 24 h after presentation in 55 (27.5%) patients, and poor long-term neurological sequelae assessed at 23 months after acute CO poisoning developed in 19.5% of the patients. The incidence of poor long-term neurological outcomes was significantly higher in the hyperthermia group than in the normothermia group. Patients with poor long-term neurological outcomes had higher maximum temperatures than patients with good outcomes. No significant difference was found in the time of hyperthermia onset within the first day according to the neurological outcomes. Hyperthermia (adjusted odds ratio (aOR) 5.009 (95% confidence interval (CI) 1.556-16.126)) and maximum temperature (aOR 2.581 (95% CI 1.098-6.063)) within the first 24 h after presentation to the emergency department were independently associated with poor long-term neurological outcomes. Body temperature measurements, which are easily and noninvasively recorded at the bedside in any facility, help to predict the risk for poor long-term neurological outcomes. This study carefully emphasizes fastidious control of pyrexia, particularly during the early period after acute CO poisoning.

Abstract
BACKGROUND Improving the process of hospital discharge is a critical priority. Interventions to improve care transitions have been shown to reduce the rate of early unplanned readmissions, and consequently, there is growing interest in improving transitions of care between hospital and home through appropriate interventions. Project Re-Engineered Discharge (RED) has shown promise in strengthening the discharge process. Although studies have analyzed the implementation of RED among private-sector hospitals, little is known about how hospitals in the Veterans Health Administration (VHA) have implemented RED. The RED implementation process was evaluated in five VHA hospitals, and contextual factors that may impede or facilitate the undertaking of RED were identified. METHODS A qualitative evaluation of VHA hospitals' implementation of RED was conducted through semistructured telephone interviews with personnel involved in RED implementation. Qualitative data from these interviews were coded and used to compare implementation activities across the five sites. In addition guided by the Practical, Robust Implementation and Sustainability Model (PRISM), cross-site analyses of the contextual factors were conducted using a consensus process. RESULTS Progress and adherence to the RED toolkit implementation steps and intervention components varied across study sites. A majority of contextual factors identified were positive influences on sites' implementation. CONCLUSION Although the study sites were able to tailor and implement RED because of its adaptability, redesigning discharge processes is a significant undertaking, requiring additional support/resources to incorporate into an organization's existing practices. Lessons learned from the study should be useful to both VHA and private-sector hospitals interested in implementing RED and undertaking a care transition intervention.

Abstract
Geriatric Patient-Aligned Care Teams (GeriPACT) were implemented in the Department of Veterans Affairs (VA) (i.e., Patient-Centered Medical Homes for older adults) to provide high quality coordinated care to older adults with more risk of negative health and psychosocial outcomes. The objectives of this paper are: (1) to present data on GeriPACT structural characteristics; and (2) to examine a composite measure of GeriPACT model consistency. We utilized a web survey targeting 71 physician leads resulting in a 62% response rate. We found GeriPACTs employed a range of staffing, empanelment, clinic space, and patient assignment practices. The mean value of the GeriPACT consistency measure was 2.03 (range: 1-4) and 6.3% of facilities were considered consistent to the GeriPACT model. We observed large variation in GeriPACT structure and in model consistency. More research is needed to understand how these variations are related to processes and outcomes of care.

Abstract
BACKGROUND Given that patient safety measures are increasingly used for public reporting and pay-for performance, it is important for stakeholders to understand how to use these measures for improvement. The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSIs) are one particularly visible set of measures that are now used primarily for public reporting and pay-for-performance among both private sector and Veterans Health Administration (VA) hospitals. This trend generates a strong need for stakeholders to understand how to interpret and use the PSIs for quality improvement (QI). The goal of this study was to develop an educational program and tailor it to stakeholders' needs. In this paper, we share what we learned from this program development process. METHODS Our study population included key VA stakeholders involved in reviewing performance reports and prioritizing and initiating quality/safety initiatives. A pre-program formative evaluation through telephone interviews and web-based surveys assessed stakeholders' educational needs/interests. Findings from the formative evaluation led to development and implementation of a cyberseminar-based program, which we tailored to stakeholders' needs/interests. A post-program survey evaluated program participants' perceptions about the PSI educational program. RESULTS Interview data confirmed that the concepts we had developed for the interviews could be used for the survey. Survey results informed us on what program delivery mode and content topics were of high interest. Six cyberseminars were developed-three of which focused on two content areas that were noted of greatest interest: learning how to use PSIs for monitoring trends and understanding how to interpret PSIs. We also used snapshots of VA PSI reports so that participants could directly apply learnings. Although initial interest in the program was high, actual attendance was low. However, post-program survey results indicated that perceptions about the program were positive. CONCLUSIONS Conducting a formative evaluation was a highly important process in program development. The useful information that we collected through the interviews and surveys allowed us to tailor the program to stakeholders' needs and interests. Our experiences, particularly with the formative evaluation process, yielded valuable lessons that can guide others when developing and implementing similar educational programs.

Abstract
BACKGROUND The lack of a tool for categorizing and differentiating hospitals according to their high reliability organization (HRO)-related characteristics has hindered progress toward implementing and sustaining evidence-based HRO practices. Hospitals would benefit both from an understanding of the organizational characteristics that support HRO practices and from knowledge about the steps necessary to achieve HRO status to reduce the risk of harm and improve outcomes. The High Reliability Health Care Maturity (HRHCM) model, a model for health care organizations' achievement of high reliability with zero patient harm, incorporates three major domains critical for promoting HROs-Leadership, Safety Culture, and Robust Process Improvement ®. A study was conducted to examine the content validity of the HRHCM model and evaluate whether it can differentiate hospitals' maturity levels for each of the model's components. METHODS Staff perceptions of patient safety at six US Department of Veterans Affairs (VA) hospitals were examined to determine whether all 14 HRHCM components were present and to characterize each hospital's level of organizational maturity. RESULTS Twelve of the 14 components from the HRHCM model were detected; two additional characteristics emerged that are present in the HRO literature but not represented in the model-teamwork culture and system-focused tools for learning and improvement. Each hospital's level of organizational maturity could be characterized for 9 of the 14 components. DISCUSSION The findings suggest the HRHCM model has good content validity and that there is differentiation between hospitals on model components. Additional research is needed to understand how these components can be used to build the infrastructure necessary for reaching high reliability.

Abstract
BACKGROUND Donor safety is the most important aspect in living-donor liver transplantation (LDLT). Gilbert syndrome is an autosomal recessive condition that is a common cause of isolated unconjugated hyperbilirubinemia, and its prevalence is not negligibly low in the general population. This study intended to assess donor safety and recipient liver function after LDLT with the use of right liver grafts from living donors with Gilbert syndrome. METHODS Among 2,140 right liver transplantations performed from January 2002 to December 20113 at our institution, we identified 12 living donors (0.6%) who showed a preoperative serum total bilirubin level of ≥2 mg/dL. These donors were clinically diagnosed with Gilbert syndrome. The clinical outcomes of these donors and their recipients were analyzed retrospectively. RESULTS The mean donor age was 24.6 ± 7.1 years, and 11 donors were male. All subjects met the preoperative evaluation conditions for right liver donation except for the level of unconjugated hyperbilirubinemia. The mean serum total bilirubin level of the donors was 2.23 ± 0.20 mg/dL before and 1.79 ± 0.61 mg/dL 1 year after right liver donation. The preoperative donor direct bilirubin level was 0.43 ± 0.19 mg/dL. The preoperative indocyanine green retention rate at 15 minutes was 8.2 ± 2.8%. All donors and recipients recovered uneventfully and were alive at the time of writing. The recipient serum total bilirubin level was 1.29 ± 0.47 mg/dL 1 year after LDLT. CONCLUSIONS We suggest that LDLT with living donors with Gilbert syndrome can be safely performed, but that a meticulous preoperative evaluation is vital to maximize donor safety.

Abstract
AIM To retrospectively analyse the synchondrosis from the occipital bone to the whole cervical spine and determine the feasibility and validity of age estimation using computed tomography (CT) images. MATERIAL AND METHODS A total of 231 cervical spine or neck CT images of young children (<7 years of age) were examined. Twelve ossification centres were assessed (occiput: n = 2; atlas: n = 2; axis, n = 6; whole sub-axial vertebra: n = 2), and the ossification process was graded as open (O, fully lucent), osseous bridging (B, partially ossified), and fusion (F, totally ossified). After the first analysis was completed, the resulting chronological chart was used to estimate the age of 10 new cases in order to confirm the usefulness of the chart. RESULTS Infancy was easily estimated using the sub-axial or C2 posterior ossification centres, while the posterior occipital regions provided good estimation of age between 1-2 years. The most difficult period for accurate age estimation was between 2-4 years. However, the C2 anterior (neurocentral ossification) and C1 posterior regions did yield information to help determine the age around 3 years. The anterior occipital region was useful for age estimation between 4-5 years, and the C1-anterior region was potentially useful to help decide among the other parameters. The test for age estimation (TAE) had a very high ICC score (0.973) among the three observers. CONCLUSION Segmentalised analysis can enhance the ability to estimate real age, at least by the year. The analysis of the occipital bone made a strong contribution to the usefulness of the chorological chart. An organised chronological chart can provide readily available information for age estimation, and the primary application of the above data (TAE) demonstrated the validity of this approach.

Abstract
Health care systems are increasingly burdened by the large numbers of safety measures currently being reported. Within the Veterans Administration (VA), most safety reporting occurs within organizational silos, with little involvement by the frontline users of these measures. To provide a more integrated picture of patient safety, the study team partnered with multiple VA stakeholders and engaged potential frontline users at 2 hospitals to develop a Guiding Patient Safety (GPS) tool. The GPS is currently in its fourth generation; once approval is obtained from senior leadership, implementation will begin. Stakeholders were enthusiastic about the GPS's user-friendly format, comprehensive content, and potential utility for improving safety. These findings suggest that stakeholder engagement is a critical first step in the development of tools that will more likely be used by frontline users. Policy makers and researchers may consider adopting this innovative partnered-research model in developing future national initiatives to deliver meaningful programs to frontline users.

Examining the validity of AHRQ's patient safety indicators (PSIs): is variation in PSI composite score related to hospital organizational factors? Med Care Res Rev 2014; 71:599-618.

Abstract
Increasing use of Agency for Healthcare Research and Quality's Patient Safety Indicators (PSIs) for hospital performance measurement intensifies the need to critically assess their validity. Our study examined the extent to which variation in PSI composite score is related to differences in hospital organizational structures or processes (i.e., criterion validity). In site visits to three Veterans Health Administration hospitals with high and three with low PSI composite scores ("low performers" and "high performers," respectively), we interviewed a cross-section of hospital staff. We then coded interview transcripts for evidence in 13 safety-related domains and assessed variation across high and low performers. Evidence of leadership and coordination of work/communication (organizational process domains) was predominantly favorable for high performers only. Evidence in the other domains was either mixed, or there were insufficient data to rate the domains. While we found some evidence of criterion validity, the extent to which variation in PSI rates is related to differences in hospitals' organizational structures/processes needs further study.

Detecting adverse events in surgery: comparing events detected by the Veterans Health Administration Surgical Quality Improvement Program and the Patient Safety Indicators. Am J Surg 2013; 207:584-95. [PMID: 24290888 DOI: 10.1016/j.amjsurg.2013.08.031] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2013] [Revised: 07/19/2013] [Accepted: 08/01/2013] [Indexed: 01/22/2023]
Abstract
BACKGROUND The Patient Safety Indicators (PSIs) use administrative data to screen for select adverse events (AEs). In this study, VA Surgical Quality Improvement Program (VASQIP) chart review data were used as the gold standard to measure the criterion validity of 5 surgical PSIs. Independent chart review was also used to determine reasons for PSI errors. METHODS The sensitivity, specificity, and positive predictive value of PSI software version 4.1a were calculated among Veterans Health Administration hospitalizations (2003-2007) reviewed by VASQIP (n = 268,771). Nurses re-reviewed a sample of hospitalizations for which PSI and VASQIP AE detection disagreed. RESULTS Sensitivities ranged from 31% to 68%, specificities from 99.1% to 99.8%, and positive predictive values from 31% to 72%. Reviewers found that coding errors accounted for some PSI-VASQIP disagreement; some disagreement was also the result of differences in AE definitions. CONCLUSIONS These results suggest that the PSIs have moderate criterion validity; however, some surgical PSIs detect different AEs than VASQIP. Future research should explore using both methods to evaluate surgical quality.

Abstract
This study compares rates of 11 Agency for Healthcare Research and Quality Patient Safety Indicators (PSIs) among 266 203 veteran dual users (ie, those with hospitalizations in both the Veterans Health Administration [VA] and the private sector through Medicare fee-for-service coverage) during 2002 to 2007. PSI risk-adjusted rates were calculated using the PSI software (version 3.1a). Rates of pressure ulcer, central venous catheter-related bloodstream infections, and postoperative sepsis, areas in which the VA has focused quality improvement efforts, were found to be significantly lower in the VA than in the private sector. VA had significantly higher rates for 7 of the remaining 8 PSIs, although the rates of only 2 PSIs (postoperative hemorrhage/hematoma and accidental puncture or laceration) remained higher in the VA after sensitivity analyses were conducted. A better understanding of system-level differences in coding practices and patient severity, poorly documented in administrative data, is needed before conclusions about differences in quality can be drawn.

Abstract
Patient safety indicators (PSIs) use inpatient administrative data to flag cases with potentially preventable adverse events (AEs) attributable to hospital care. This study explored how many AEs the PSIs identified in the 30 days post discharge. PSI software was run on Veterans Health Administration 2003-2007 administrative data for 10 recently validated PSIs. Among PSI-eligible index hospitalizations not flagged with an AE, this study evaluated how many AEs occurred within 1 to 14 and 15 to 30 days post discharge using inpatient and outpatient administrative data. Considering all PSI-eligible index hospitalizations, 11 141 postdischarge AEs were identified, compared with 40 578 inpatient-flagged AEs. More than 60% of postdischarge AEs were detected within 14 days of discharge. The majority of postdischarge AEs were decubitus ulcers and postoperative pulmonary embolisms or deep vein thromboses. Extending PSI algorithms to the postdischarge period may provide a more complete picture of hospital quality. Future work should use chart review to validate postdischarge PSI events.

Abstract
This study examines whether Agency for Healthcare Research and Quality Patient Safety Indicators (PSIs) Postoperative Wound Dehiscence (PWD) and Accidental Puncture or Laceration (APL) events reflect problems with hospital processes of care (POC). The authors randomly selected 112 PSI-flagged PWD/APL discharges from 2002-2007 VA administrative data, identified true cases using chart review, and matched cases with controls. This yielded a total of 95 case-control pairs per PSI. Patient information and clinical processes on each case-control pair were abstracted from the electronic medical record (EMR). Although PWD cases and controls differed on incision and closure types, APL cases and controls were comparable in examined processes. Further exploration of the process differences between PWD cases and controls indicated that they were primarily caused by patients' underlying surgical problems rather than quality of care shortfalls. Documentation of POC was frequently missing in EMRs. Future studies should combine EMR review with alternative approaches, such as direct observation, to better assess POC.

Is development of postoperative venous thromboembolism related to thromboprophylaxis use? A case-control study in the Veterans Health Administration. Jt Comm J Qual Patient Saf 2012; 38:348-58.

Abstract
BACKGROUND Observational studies continue to report thromboprophylaxis underuse for postoperative pulmonary embolism/deep vein thrombosis (pPE/DVT) despite the long-standing existence of prevention guidelines. However, data are limited on whether thromboprophylaxis use differs between patients developing pPE/DVT versus those who do not or on why prophylaxis is withheld. METHODS Administrative data (2002-2007) from 28 Veterans Health Administration hospitals were screened for discharges with (1) pPE/DVT as flagged by the Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicator software and (2) pharmacoprophylaxis-recommended procedures, and the medical records were reviewed to ascertain true pPE/DVT cases. Controls were selected by matching cases by hospital, age, sex, diagnosis-related group, and predicted probability for developing pPE/DVT, and who underwent a pharmacoprophylaxis-recommended procedure. Records were assessed for "appropriate pharmacoprophylaxis use," defined primarily per American College of Chest Physicians (ACCP) guidelines, and reasons for anticoagulant nonuse. RESULTS The 116 case-control pairs were similar in terms of demographics, surgery type, ACCP risk category, and appropriate pharmacoprophylaxis rates overall. Of the highest-risk patients, respective pharmacoprophylaxis rates among cases and controls were 88% versus 92% among hip/knee replacements and 31% versus 48% among cancer patients. Of the cases and controls who did not receive appropriate pharmacoprophylaxis, only about 25% had documented contraindications. Reviewers identified contraindications in 14% of cases and 9% of controls. CONCLUSIONS Similarities in preventive pPE/DVT practice between cases and controls suggest that pPE/DVTs occur despite implementation of guideline-adherent practices.

Abstract
Naegleria fowleri, a free-living amoeba, is the causative pathogen of primary amoebic meningoencephalitis in humans and experimental mice. N. fowleri is capable of destroying tissues and host cells through lytic necrosis. However, the mechanism by which N. fowleri induces host cell death is unknown. Electron microscopy indicated that incubation of Jurkat T cells with N. fowleri trophozoites induced necrotic morphology of the Jurkat T cells. N. fowleri also induced cytoskeletal protein cleavage, extensive poly (ADP-ribose) polymerase hydrolysis and lactate dehydrogenase (LDH) release. Although no activation of caspase-3 was observed in Jurkat T cells co-incubated with amoebae, intracellular reactive oxygen species (ROS) were strongly generated by NADPH oxidase (NOX). Pretreating cells with necroptosis inhibitor necrostatin-1 or NOX inhibitor diphenyleneiodonium chloride (DPI) strongly inhibited amoeba-induced ROS generation and Jurkat cell death, whereas pan-caspase inhibitor z-VAD-fmk did not. N. fowleri-derived secretory products (NfSP) strongly induced intracellular ROS generation and cell death. Necroptotic effects of NfSP were effectively inhibited by pretreating NfSP with proteinase K. Moreover, NfSP-induced LDH release and intracellular ROS accumulation were inhibited by pretreating Jurkat T cells with DPI or necrostatin-1. These results suggest that N. fowleri induces ROS-dependent necroptosis in Jurkat T cells.

Abstract
Entamoeba histolytica is known to induce host cell death via activation of calpain and caspases. In this study, we investigated the specific proteases involved in the degradation of cytoskeletal proteins during Jurkat T-cell death induced by E. histolytica. Amoebic trophozoites induced marked degradation of paxillin, Cas, vimentin, vinculin and talin, as well as α- or β-spectrin, in Jurkat T cells. The cleavage effects of E. histolytica were strongly retarded by pretreatment with a calpain inhibitor, but not with a pan-caspase inhibitor. In addition, calpain knockdown with siRNA in Jurkat T cells effectively inhibited E. histolytica-induced PARP, paxillin, α-spectrin, β-spectrin and talin degradation, as compared to scrambled siRNA. These results suggest that calpain plays a crucial role in the cleavage of cytoskeletal proteins during cell death induced by E. histolytica.

Abstract
BACKGROUND The Agency for Healthcare Research and Quality Patient Safety Indicator postoperative respiratory failure (PRF) uses administrative data to screen for potentially preventable respiratory failure after elective surgery based on a respiratory failure diagnosis or an intubation or ventilation procedure code. Data on PRF accuracy in identifying true events is scant; a recent study using University HealthSystem Consortium data found a positive predictive value (PPV) of 83%. We examined the indicator's PPV in the Veterans Health Administration. STUDY DESIGN We applied the Patient Safety Indicator software (v.3.1a) to fiscal year 2003-2007 VA discharge data. Trained abstractors reviewed medical records of 112 software-flagged PRF cases. We calculated the PPV and examined false positives to determine reasons for incorrect identification and true positives to determine clinical consequences and potential risk factors of PRF. RESULTS Seventy-five cases were true positive (PPV 67%; 95% CI, 57-76%); 13% were identified by a diagnosis code, 53% by a procedure code, 33% by both. Of false positives, 19% represented coding errors, 76% represented nonelective admissions. Of true positives, 28% of patients died, 56% had an American Society of Anesthesiologists level higher than II. Of associated index procedures, 53% were abdominal/pelvic, and 56% lasted >3 hours. CONCLUSIONS Based on our and University HealthSystem Consortium's findings, PRF should continue to be used as a screen for potential patient-safety events. Its PPV could be substantially improved in the Veterans Health Administration through introduction of an admission status code. Many PRF-identified cases appeared to be at high risk, based on patient and procedure-related factors. The degree to which such cases are truly preventable events requires additional assessment.

Abstract
The Seoul cancer registry was established in 1991. Cancer is a notifiable disease, and registration of cases is done by passive and active methods. The registry contributed survival data for 56 cancer sites or types registered during 1993-1997. Follow-up information has been gleaned predominantly by passive methods with median follow-up ranging between 5-82 months for various cancers. The proportion with histologically verified diagnosis for different cancers ranged between 23-99%; death certificates only (DCOs) comprised 0-67%; 33-100% of total registered cases were included for survival analysis. The top-ranking cancers on 5-year age-standardized relative survival rates were testis and placenta (95%), thyroid (93%), non-melanoma skin (93%), corpus uteri (79%), renal pelvis (77%), cervix (76%), Hodgkin lymphoma (75%), breast (74%) and prostate (74%). Five-year relative survival by age group showed a decreasing trend with increasing age groups for cancers of the small intestine, colon, gall bladder, cervix, corpus uteri, ovary, kidney, urinary bladder and thyroid, or was fluctuating for other cancers.

Abstract
BACKGROUND We determined cardiovascular responses to tracheal intubation in relation to the time since injury in patients with different levels of spinal cord injury. METHODS Two hundred and fourteen patients with complete cord injury were studied. They were either quadriplegics (>C7, n=71) or paraplegics (<T5, n=143), and were subdivided into six groups each according to the time since injury: <4 week (acute), 4 week-1 yr, 1-5, 5-10, 10-20, and >20 yr. Twenty patients with no cord injury served as controls. Systolic arterial pressure (SAP), heart rate (HR), and plasma catecholamine concentrations were determined. RESULTS Intubation did not affect SAP in the quadriplegics regardless of the time post-injury, but it significantly increased SAP in all paraplegics. Moreover, the pressor response was enhanced in the paraplegics who were 10 yr or more since injury (P<0.05). HR increased significantly in all groups; the magnitude of the increase was less only in acute quadriplegics compared with controls. Plasma concentrations of norepinephrine increased in every group except for the quadriplegics within 4 weeks of injury. The maximum increases in SAP, HR, and norepinephrine from awake baseline values were smaller in the quadriplegics than in the paraplegics (P<0.01). CONCLUSIONS The cardiovascular and catecholamine responses to intubation change as a function of the time elapsed and the level of the cord injury. In this study, the pressor response to tracheal intubation was abolished in the quadriplegics but not in paraplegics; indeed, it was enhanced at 10 yr or more since injury in this group.

Abstract
Host cell death induced by Entamoeba histolytica is an important mechanism for both host defence and microbial immune evasion during human amoebiasis. However, the signalling pathways underlying cell death induced by E. histolytica are not fully understood. This study investigated the involvement of the protein tyrosine phosphatases (PTPs) SHP-1 and SHP-2 in the dephosphorylation associated with E. histolytica-induced host cell death. Incubation with E. histolytica resulted in a marked decrease in protein tyrosine phosphorylation levels and degradation of SHP-1 or SHP-2 in Jurkat cells. Pre-treatment of cells with a calpain inhibitor, calpeptin, impeded the amoeba-induced dephosporylation and cleavage of SHP-1 or SHP-2. Additionally, inhibition of PTPs with phenylarsine oxide (PAO) attenuated Entamoeba-induced dephosphorylation and DNA fragmentation in Jurkat T cells. These results suggest that calpain-dependent cleavage of SHP-1 and SHP-2 may contribute to protein tyrosine dephosphorylation in Jurkat T cell death induced by E. histolytica.

Abstract
BACKGROUND The trigger tool methodology uses clinical algorithms applied electronically to 'flag' medical records where adverse events (AEs) have most likely occurred. The authors sought to create surgical triggers to detect AEs in the ambulatory care setting. METHODS Four consecutive steps were used to develop ambulatory surgery triggers. First, the authors conducted a comprehensive literature review for surgical triggers. Second, a series of multidisciplinary focus groups (physicians, nurses, pharmacists and information technology specialists) provided user input on trigger selection. Third, a clinical advisory panel designed an initial set of 10 triggers. Finally, a three-phase Delphi process (surgical and trigger tool experts) evaluated and rated the suggested triggers. RESULTS The authors designed an initial set of 10 surgical triggers including five global triggers (flagging medical records for the suspicion of any AE) and five AE-specific triggers (flagging medical records for the suspicion of specific AEs). Based on the Delphi rating of the trigger's utility for system-level interventions, the final triggers were: (1) emergency room visit(s) within 21 days from surgery; (2) unscheduled readmission within 30 days from surgery; (3) unscheduled procedure (interventional radiological, urological, dental, cardiac or gastroenterological) or reoperation within 30 days from surgery; (4) unplanned initial hospital length of stay more than 24 h; and (5) lower-extremity Doppler ultrasound order entry and ICD code for deep vein thrombosis or pulmonary embolus within 30 days from surgery. CONCLUSION The authors therefore propose a systematic methodology to develop trigger tools that takes into consideration previously published work, end-user preferences and expert opinion.

Abstract
This study evaluated the feasibility of applying a visible-light-activated photocatalytic technique to cleanse air dimethyl disulphide (DMDS) at low concentration conditions (0.027-5.4 ppm), by using nitrogen-enhanced TiO2. In addition, the applicability of a backup adsorption unit for the secondary control of DMDS exiting from the photocatalytic oxidation (PCO) unit was investigated. The PCO unit functioned effectively for the control of DMDS at low concentration levels ( < or = 0.027 ppm) for long-time periods (at least 603 h). However, rapid photocatalyst deactivation levels were observed during photocatalytic processes with a higher DMDS input concentration (IC) (2.7 ppm). The photocatalyst reactivated with humidified or dried air, under visible-light irradiation, did not regain all its initial activities. The photocatalytic degradation efficiencies (PDEs) for DMDS were close to 100% for the relative humidity (RH) range of 45-55%, whereas they were between 86% and 91% and between 78% and 82% regarding the RH ranges of 10-20% and 80-90%, respectively. The PDEs via the PCO alone were close to 100% during this time period for the lowest IC conditions (0.027 ppm), whereas they decreased gradually for the other ICs. The FTIR spectra of the photocatalysts, as well as a solid-liquid extraction method, suggested the formation of sulphate groups on the catalyst surface during a photocatalytic process. Methanol was identified as a gaseous by-product. In addition, the backup adsorption unit could be effectively utilized to remove methanol, under a broad indoor pollution level (0.027-5.4 ppm), as well as DMDS exiting from the PCO units.

Abstract
BACKGROUND The intensity of nociceptive stimuli reflects the severity of tissue injury. The anaesthetic requirement and stress hormonal responses were determined to learn whether they differ according to different surgical approaches (anterior vs. posterior) during the spinal surgery. METHODS Patients undergoing lumbar spine surgery without neurological deficits were divided into two groups: one having posterior (n=13) and the other having anterior fusion (n=13). The end-tidal sevoflurane concentrations (ET(SEVO)) required to maintain the bispectral index score at 40-50 were determined. Mean arterial pressure (MAP), heart rate (HR), central venous pressure (CVP), serum osmolality and plasma concentrations of catecholamines, cortisol and vasopressin (AVP) were measured. RESULTS There were no differences in MAP, HR, CVP and serum osmolality between the groups. ET(SEVO) was higher in the anterior than in the posterior group (P<0.05). The plasma concentrations of norepinephrine and cortisol increased in both groups during the surgery, whereas those of epinephrine remained unchanged. AVP concentrations increased during the surgery in the anterior group, and remained unaltered in the posterior group. The anterior group needed more analgesics (P<0.01) during the first 1 h after the operation. CONCLUSIONS The anterior approach required a deeper level of anaesthesia while undergoing spinal surgery and more use of post-operative analgesics than the posterior approach. It was also associated with a more pronounced AVP release during the surgery.

Abstract
BACKGROUND Eosinophils are important effector cells in the pathogenesis of allergic diseases such as bronchial asthma. Oxidative stress in the form of cellular reactive oxygen species (ROS) has been implicated in the pathogenesis of several allergic diseases. Recently, it has become evident that mitochondrial-derived ROS are important transducers of apoptosis and intracellular signaling. In this study, we investigated the role of mitochondrial ROS in the activation of extracellular signal-regulated kinases (ERK) 1 and 2-mitogen-activated protein kinase (MAPK) and caspase-3 in human eosinophils stimulated with H2O2. METHODS Human eosinophils were purified using immunomagnetic negative selection and then stimulated with H2O. H2O2-induced eosinophil apoptosis was measured by staining cells with annexin V. Activation of ERK1/2 MAPK and caspases was assessed by Western blotting. Eosinophils were pretreated with rotenone, an inhibitor of the mitochondrial electron transport chain, before H2O2 was added. RESULTS Treatment with 1 mM H2O2 induced externalization of phosphatidylserine (PS) and activation of caspases in eosinophils. H2O2-triggered PS externalization and cleavage of caspase-3 were markedly inhibited by pretreatment with the mitochondrial ROS scavenger N-acetyl-L-cysteine. In addition, H2O2 strongly induced phosphorylation of ERK1/2, but not ERK5, in eosinophils. Hydrogen peroxide-triggered activation of caspase-3 and ERK1/2 was attenuated by pretreatment with rotenone. CONCLUSIONS These results suggest that mitochondrial respiration is essential for activation of ERK1/2 and caspase-3 in human eosinophils stimulated with H2O2.

Abstract
Neutrophils are the predominant inflammatory cells found in the vaginal discharge of patients with Trichomonas vaginalis infection. However, it is not known whether neutrophil apoptosis is induced by live T. vaginalis. Therefore, we examined whether T. vaginalis can influence neutrophil apoptosis, and also whether caspase-3 and the Bcl-2 family members are involved in the apoptosis. Thus, human neutrophils were incubated with live T. vaginalis and neutrophil apoptosis was evaluated by Giemsa, annexin V-PI, and DiOC6 stainings. The neutrophil apoptosis was significantly higher in those incubated with T. vaginalis than in the control group. When trichomonads were pre-treated with mAb to AP65 (adhesin protein), or when trophozoites were separated from neutrophils using a Transwell chamber, neutrophil apoptosis was significantly reduced. The activation of caspase-3 was evident in neutrophils undergoing spontaneous apoptosis but was markedly enhanced during T. vaginalis-induced apoptosis. Moreover, the inhibition of caspase-3 effectively reduced T. vaginalis-induced apoptosis. Trichomonad-induced apoptosis was also associated with reduced expression of the neutrophil anti-apoptotic protein, Mcl-1. These results indicate that T. vaginalis alters Mcl-1 expression and caspase-3 activation, thereby inducing apoptosis of human neutrophils.

Abstract
OBJECTIVE To investigate patients with posterior cerebral artery (PCA) infarctions to learn whether hemispatial neglect is more frequent and severe after right than left PCA infarction; whether visual field defects (VFDs) influence the presence or severity of hemispatial neglect; and the anatomic loci of lesions that are associated with hemispatial neglect. METHODS The authors recruited 45 patients with PCA infarction that involved only the occipital lobe or the occipital lobe plus other areas served by the PCA. All subjects received seven neglect tests within 2 months after onset. RESULTS Overall, the frequency of hemispatial neglect was 42.2%. The frequency did not significantly differ between the right (48.0%) and left (35.0%) PCA groups, but the severity of hemispatial neglect was significantly greater in the right group. VFD alone did not influence the frequency or severity of neglect after controlling other variables. Isolated occipital lesions were rarely associated with hemispatial neglect, and it was only the occipital plus splenial lesion that significantly influenced the frequency and severity of neglect. CONCLUSIONS This study suggests that after excluding such confounding factors as aphasia or hemiplegia, neglect frequency does not differ between the right and left posterior cerebral artery (PCA) groups, but the severity of neglect is greater after right PCA infarctions; even in the acute stage of PCA infarction; visual field defect from an isolated occipital lesion does not cause hemispatial neglect; and the injury to both the occipital lobe and the splenium of the corpus callosum is important for producing hemispatial neglect with PCA infarction.

Abstract
PURPOSE To ascertain the factors associated with the proportion of death certificate only (DCO) cases contained in the Kwangju Cancer Registry (KCR) that are not as yet in the good range. MATERIALS AND METHODS The distribution of DCO cases was analyzed by sex, age, cancer site, histological verification (HV) as well as the physician's death certificate status. RESULTS All cases (n=4,243) in Kwangju diagnosed as having cancer between 1997 and 1998 were registered with the KCR. Death certificates (n=2,390) reporting cancer as the causes of death were collected from the National Statistics Office and reviewed with hospital data linkage and a total of 590 cases were registered as DCO. DCOs accounted for 12.2% (male 12.8%, female 11.5%) of all registrations in Kwangju, 1997~1998. The proportion of DCO cases was high in subjects under 15 (male13.5%,female 9.4%) as well as those 75 and over (male 20.3%, female 27.2%). For cancer sites, the proportion of DCO cases was high (over 10%) for liver, bronchus-lung, esophagus and pancreas and low (under 3%) for skin, bladder, uteri cervix and breast. The proportion of DCO cases was inversely associated with HV%. When the death certificate was issued by physician, the possibility of DCO decreased. CONCLUSION The proportion of DCO is positively associated with increasing age and negatively associated with HV% and the issuance of a physician's death certificate. These findings suggest that further socio-cultural efforts are required to reduce the DCO proportion.
