Background: This study quantifies incremental healthcare expenditures of functional impairments and phenotypic frailty in specific healthcare sectors.

Methods: Pooled 2023 analysis of 4 prospective cohort studies linked with Medicare claims including 4 318 women and 3 847 men attending an index examination (2002-2011). Annualized inpatient, skilled nursing facility (SNF), home healthcare (HHC), and outpatient costs (2023 dollars) ascertained for 36 months following index examination.

Background: Low neighborhood socioeconomic status is associated with adverse health outcomes, but its association with health care costs in older adults is uncertain.

Objectives: To estimate the association of neighborhood Area Deprivation Index (ADI) with total, inpatient, outpatient, skilled nursing facility (SNF), and home health care (HHC) costs among older community-dwelling Medicare beneficiaries, and determine whether these associations are explained by multimorbidity, phenotypic frailty, or functional impairments.

Design: Four prospective cohort studies linked with each other and with Medicare claims.

Guidelines strongly recommend trauma-focused therapies to treat posttraumatic stress disorder. Implementation of cognitive processing therapy (CPT) and prolonged exposure (PE) in Veterans Health Administration (VHA) and non-VHA settings began in 2006. We conducted a systematic review of implementation facilitators and challenges and strategies to address barriers.

Background: Improving access to evidence-based psychotherapies (EBPs) is a Veterans Health Administration (VHA) priority. Cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and mindfulness-based stress reduction (MBSR) are effective for chronic pain and several mental health conditions. We synthesized evidence on implementation strategies to increase EBP access and use.

Cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and mindfulness-based stress reduction (MBSR) have demonstrated effectiveness for improving outcomes in chronic pain. These evidence-based psychotherapies (EBPs) remain underutilized in clinical practice, however. To identify research gaps and next steps for improving uptake of EBPs, we conducted a systematic review of patient-, provider-, and system-level barriers and facilitators of their use for chronic pain.

Background: Care coordination (CC) interventions involve systematic strategies to address fragmentation and enhance continuity of care. However, it remains unclear whether CC can sufficiently address patient needs and improve outcomes.

Methods: We searched MEDLINE, CINAHL, Embase, Cochrane Database of Systematic Reviews, AHRQ Evidence-based Practice Center, and VA Evidence Synthesis Program, from inception to September 2019.

Background: Most US adults with posttraumatic stress disorder (PTSD) do not initiate mental health treatment within a year of diagnosis. Increasing treatment uptake can improve health and quality of life for those with PTSD. Individuals with PTSD are more likely to report poor physical functioning, which may contribute to difficulty with treatment initiation and retention.

Background: With continued growth in the older adult population, US federal and state costs for long-term care services are projected to increase. Recent policy changes have shifted funding to home and community-based services (HCBS), but it remains unclear whether HCBS can prevent or delay long-term nursing home placement (NHP).

Methods: We searched MEDLINE (OVID), Sociological Abstracts, PsycINFO, CINAHL, and Embase (from inception through September 2018); and Cochrane Database of Systematic Reviews, Joanna Briggs Institute Database, AHRQ Evidence-based Practice Center, and VA Evidence Synthesis Program reports (from inception through November 2018) for English-language systematic reviews.

Background: Complex health care interventions involve multiple distinct elements that contribute to their functioning. Conducting systematic reviews of complex interventions has substantial challenges. Although methodological guidance exists, less is known about the practical strategies and approaches undertaken by systematic review groups to navigate common challenges and enhance impacts of systematic review findings.

Introduction: Sex- and gender-specific science is essential to inform patient-centered, evidence-based care. Developing such evidence requires adequate inclusion of both women and men in trials. We sought to describe study participation of women and men in Department of Veterans Affairs Health Services Research and Development trials.

Background: Hospitalization-associated functional decline is a common problem for older adults, but it is unclear how hospitalizations affect physical performance measures such as gait speed. We sought to determine hospitalization-associated change in gait speed and likelihood of new limitations in mobility and activities of daily living (ADLs).

Methods: We used longitudinal data over 5 years from the Health, Aging and Body Composition Study, a prospective cohort of black and white community-dwelling men and women, aged 70-79 years, who had no limitations in mobility (difficulty walking 1/4 mile or climbing 10 steps) or ADLs (transferring, bathing, dressing, and eating) at baseline.
