Urinary albumin-creatinine ratio (UACR) and urinary protein-creatinine ratio (UPCR) are both used in clinical practice to diagnose and monitor chronic kidney disease (CKD). Which measure exhibits stronger associations with clinical outcomes and whether this varies by patient characteristics are unknown.

Safe and reliable venous access is critical for high-quality cancer care. Patients with both solid and hematologic cancers require vascular access devices (VADs) for systemic chemotherapies and for supportive treatments, including blood products, antimicrobials, antiemetics, and fluids. However, VADs are associated with serious complications, including bloodstream infection and venous thromboembolism. Evidence-based guidance could maximize benefits and reduce risks in the selection and management of VADs in patients with cancer. The authors convened a 9-member international multidisciplinary panel and used the RAND/UCLA Appropriateness Method to develop recommendations for VAD selection, insertion, and management in patients with cancer. A literature review informed the development of clinical scenarios, which were rated by the panel for appropriateness based on cancer type, treatment indication, urgency, comorbidities, and anticipated duration of use. Of 1422 scenarios, 502 (35%) were rated as appropriate, 400 (28%) were rated as neutral/uncertain, and 520 (37%) were rated as inappropriate. Appropriateness of VAD selection varied by type of cancer, treatment urgency, and planned dwell time. For patients with acute hematologic cancers requiring urgent chemotherapy, placement of a double-lumen peripherally inserted central catheter (PICC) or a tunneled central venous catheter (CVC) was rated as appropriate, regardless of treatment intensity or infusate characteristics. For patients with malignant solid tumors, a single-lumen tunneled CVC or implanted port was rated as appropriate for delivering chemotherapy, regardless of treatment intensity, urgency, or duration. In patients with advanced chronic kidney disease, coordination of care with a nephrologist to ensure vein preservation in the context of cancer prognosis was recommended. By developing comprehensive, evidence-informed expert recommendations, the Michigan Appropriateness Guide for Intravenous Catheters in Adult Patients With Cancer (MAGIC-ONC) aims to improve clinical care, reduce complications, support quality improvement efforts, and advance the safety of vascular access for patients with cancer.

The comparative gastrointestinal safety across glucagon-like peptide-1 receptor agonists and tirzepatide is still unclear.

Evidence synthesis and guideline groups have the potential to address health disparities. In June 2024, the Agency for Healthcare Research and Quality (AHRQ) and the Robert Wood Johnson Foundation (RWJF) cosponsored a summit to address racial and ethnic health equity in systematic reviews and other syntheses and guidelines, with support from Cochrane US. This article summarizes cross-cutting themes around future directions for systematic reviews and guidelines. Discussions addressed include the rationale for addressing racial health equity in systematic reviews and guidelines; representation of people with lived experience in systematic reviews and guidelines; approaches to developing and addressing equity-focused scope, including frameworks, methods, and thoughtful interpretation in systematic reviews; challenges and opportunities for guideline recommendations; need for standardized language and reporting for race and ethnicity in primary research studies, systematic reviews, and guidelines; and measures to track the progress of incorporating and addressing racial and ethnic health equity in systematic reviews and guidelines. Participants acknowledged that a one-size-fits-all approach was not possible or desired. Consensus priorities for next steps were to develop methods guidance to address equity in systematic reviews and guidelines; develop measures to track the progress of addressing racial and health equity in systematic reviews and guidelines; operationalize engaging representative interest holders in systematic reviews and guidelines; and share resources and learning for advancing health equity.

Racial and ethnic health equity is the absence of unfair and avoidable or remediable differences in health and well-being among persons belonging to different racial and ethnic groups. This article summarizes current guidance and identifies practices for systematic reviewers and guideline groups to develop clinical practice guidelines that mitigate such inequities. Current guidance recommends that systematic reviews and clinical practice guidelines ensure a wider perspective; identify, prioritize, and develop equity-focused topics and questions; and apply specific methods and processes to answer equity-focused questions. Ensuring a wider perspective involves incorporating persons with lived experiences and other relevant nonclinical expertise into review and guideline teams as well as engagement of patients and members of affected populations in the review and guideline process. Examples for identifying and developing equity-focused topics and questions include using health equity as a criterion to select and prioritize topics, developing topics specific to mitigating racial and ethnic health inequities, and addressing upstream drivers of inequities and implementation considerations. Appropriate methods and processes might include considering different types of study designs, selecting the type of review accordingly, and using suitable evidentiary frameworks and thresholds to answer a broader set of equity-relevant questions. Several review, health technology assessment, guideline, and other health care decision-maker groups are implementing guidance to address racial and ethnic health equity.

Patients with irritable bowel syndrome (IBS) frequently seek dietary advice, but few evidence-based options exist. Major societal guidelines recommend traditional dietary advice (TDA) as first-line therapy, with the cumbersome and resource-intensive low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet reserved as second-line therapy. Recent pilot data suggest that the Mediterranean diet (MD), renowned for its general health benefits, improves IBS symptoms, but whether it can be considered another first-line dietary option is unknown.

Although physical activity recommendations increasingly consider daily step counts, it remains unclear whether step accumulation patterns-short versus sustained longer bouts-affect associations with mortality and cardiovascular disease (CVD) among suboptimally active populations.

Clinical practice guidelines (CPGs) may not consistently address racial and ethnic health equity (RHE). This article discusses an audit of CPGs in the ECRI Guidelines Trust (EGT) aiming to summarize the extent and context in which CPGs address RHE, determine use of race-based recommendations, and determine inclusion of patient or public perspectives representing a racially or ethnically diverse group. A working group searched the EGT from 1 January 2020 to 31 January 2025 using RHE-related terms. They included CPGs that were developed by a U.S. organization in an adult population and underpinned by a systematic review that used RHE-related terms. They reviewed included CPGs and their supporting materials, extracted key characteristics, and narratively summarized key findings. The working group identified 137 full-text CPGs. Of these, 105 explicitly addressed RHE terms, whereas the remainder discussed equity or disparities more broadly. When explicitly addressed, RHE was most commonly included as part of the implementation considerations or in the discussion (78.1%). When incorporated into the conduct or methods of developing a guideline recommendation (64.7%), RHE was addressed in the search (8.8%), methods (33.8%), results (41.1%), or EtD or recommendation (39.7%). Although none of the guidelines included a race-based recommendation, 22.8% identified RHE evidence gaps. In total, 84.7% described racial and/or ethnic disparities in the clinical condition and 20% explicitly stated that race is a social construct. Only 3.3% expressly incorporated a racially or ethnically diverse patient or public perspective. However, the search was limited to the EGT, and search terms may not represent the full scope of RHE. Among CPGs addressing health equity, explicit consideration of RHE is mostly addressed in implementation considerations, with less incorporation into the methods or guideline recommendation.

Recent developments and controversies in organ transplantation necessitate the reaffirmation and application of foundational ethical norms as the laudable goal of increasing viable organs for transplantation is pursued. The physician's primary duties are to individual patients under the physician's care. For physicians of prospective donor-patients, the "bright line" between serving the best interests of donor-patients and their families and serving potential recipient-patients and the public interest can become blurred in ethically problematic ways. This paper provides ethical guidance for clinicians involved in organ transplantation as well as for patients, families, the public, policymakers, and others to help maintain trust and encourage participation in this life-saving enterprise. It clarifies the duties and roles of care teams of prospective donor-patients, recipient-patients, and organ procurement teams, reaffirming that end-of-life decision making for prospective donor-patients must center on the best interests of donor-patients and their families independent of organ donation potential. It also emphasizes the importance of truly informed consent for organ donation and advocates for prioritizing equity and transparency in transplantation processes.

Systematic reviews and other evidence synthesis products support clinical practice guidelines, policy and coverage decisions, and future research directions. These products can help promote health equity by examining why differences in outcomes exist, how underrepresentation or overrepresentation in the evidence affects generalizability, and how to address underlying societal sources of disparities. This article provides an overview of and background for a series of articles sponsored by the Agency for Healthcare Research and Quality and the Robert Wood Johnson Foundation. The series focuses on racial and ethnic health equity as one approach to enhance the utility of systematic reviews in addressing inequities. Together, the articles in the series address what end users of systematic reviews, specifically guideline developers, have done thus far; how best to methodologically address racial health equity; and what steps to take next.
