Background: AUA guidelines for shared decision making (SDM) in prostate cancer recommend discussion of five content areas in consultations: (1) cancer severity (tumor risk (TR), pathology results (PR)); (2) life expectancy (LE); (3) cancer prognosis (CP); (4) baseline urinary and erectile function (UF and EF); and (5) treatment side effects (erectile dysfunction (ED), urinary incontinence (UI), and irritative urinary symptoms (LUTS)). However, patient retention of information after the visit and inconsistent risk communication by physicians are barriers to informed SDM. We sought to develop natural language processing (NLP) models based on recorded consultations to provide key information to patients and audit quality of physician communication.

Patients with suspected or confirmed high-consequence infectious diseases (HCIDs) may present for care at any acute care facility. However, there are limited data to inform recommendations for the design, maintenance, and operation of isolation spaces for patients with suspected or confirmed HCIDs. To address this gap, we developed consensus statements by convening a group of 29 subject matter experts to participate in a modified Delphi process facilitated by a validated tool (the RAND-developed ExpertLens system).

Specialty drugs are high-cost medications often used to treat complex chronic conditions. Even with insurance coverage, patients may face very high out-of-pocket costs, which in turn may restrict access. While the Inflation Reduction Act of 2022 included policies designed to reduce specialty drug costs, relatively few policies have been enacted during the past decade.

Background: The current Institute of Medicine (IOM) pregnancy weight gain guidelines were developed using the best available evidence but were limited by substantial knowledge gaps. Some have raised concern that the guidelines for individuals affected by overweight or obesity are too high and contribute to short- and long-term complications for the mother and child.

Objectives: To determine the association between pregnancy weight gain below the lower limit of the current IOM recommendations and risk of 10 adverse maternal and child health outcomes among individuals with overweight and obesity.

Background: The transition from pediatric to adult care poses a significant health system-level challenge impeding the delivery of quality health services for youth with chronic health conditions. In Canada and globally, the transition to adult care is regarded as a top priority in adolescent health in need of readily applicable, adaptable, and relevant national metrics to evaluate and benchmark transition success across disease populations and clinical care settings. Unfortunately, existing literature fails to account for the lack of engagement from youth and caregivers in developing indicators, and its applicability across chronic conditions, primary care involvement, and health equity considerations.

Introduction: Patient engagement and integrated knowledge translation (iKT) processes improve health outcomes and care experiences through meaningful partnerships in consensus-building initiatives and research. Consensus-building is essential for engaging a diverse group of experienced knowledge users in co-developing and supporting a solution where none readily exists or is less optimal. Patients and caregivers provide invaluable insights for building consensus in decision-making around healthcare, policy and research.

Background: Physician treatment preference may influence how risks are communicated in prostate cancer consultations. We identified persuasive language used when describing cancer prognosis, life expectancy, and side effects in relation to a physician's recommendation for aggressive (surgery/radiation) or nonaggressive (active surveillance/watchful waiting) treatment.

Methods: A qualitative analysis was performed on transcribed treatment consultations of 40 men with low- and intermediate-risk prostate cancer across 10 multidisciplinary providers.

Background: The Institute of Medicine pregnancy weight gain guidelines were developed without evidence linking high weight gain to maternal cardiometabolic disease and child obesity. The upper limit of current recommendations may be too high for the health of the pregnant individual and child.

Objectives: The aim of this study was to identify the range of pregnancy weight gain for pregnancies within a normal body mass index (BMI) range that balances the risks of high and low weight gain by simultaneously considering 10 different health conditions.

Article Synopsis
  • * The study aimed to gather expert opinions from palliative care and addiction specialists about treating different clinical scenarios involving opioid misuse in cancer patients through a modified Delphi approach.
  • * Key findings included that buprenorphine/naloxone is appropriate for treating patients with untreated OUD, while the appropriateness of methadone varies based on prognosis; overprescribing of opioids by non-OUD patients was also found to require careful consideration, depending on their medical history and prognosis.

In 2015, the Centers for Medicare and Medicaid Services announced the Medicare Advantage (MA) Value-Based Insurance Design (VBID) model test, which allows MA insurers to use flexible benefit design strategies, such as reduced cost-sharing, to encourage beneficiaries with chronic disease to use high-value care. During the first year of implementation (2017), nine MA insurers offered VBID in 45 health plans to a total of 96 053 eligible beneficiaries. We used MA encounter data to estimate the impact of VBID on health services utilization in 2017 using a difference-in-differences research design.

Purpose: Men with prostate cancer prefer patient-specific, quantitative assessments of longevity in shared decision making. We sought to characterize how physicians communicate the 3 components of competing risks-life expectancy (LE), cancer prognosis and treatment-related survival benefit-in treatment consultations.

Materials And Methods: Conversation related to LE, cancer prognosis and treatment-related survival benefit was identified in transcripts from treatment consultations of 42 men with low- and intermediate-risk disease across 10 multidisciplinary providers.

Importance: Metrics that detect low-value care in common forms of health care data, such as administrative claims or electronic health records, primarily focus on tests and procedures but not on medications, representing a major gap in the ability to systematically measure low-value prescribing.

Objective: To develop a scalable and broadly applicable metric that contains a set of quality indicators (EVOLV-Rx) for use in health care data to detect and reduce low-value prescribing among older adults and that is informed by diverse stakeholders' perspectives.

Design, Setting, And Participants: This qualitative study used an online modified-Delphi method to convene an expert panel of 15 physicians and pharmacists.
