Risk adjustment is a critical component of health care reimbursement aimed at ensuring fair compensation on the basis of the characteristics of patients receiving care. Optimizing risk adjustment is not just a matter of improving efficiency or predictive accuracy; it is a crucial step toward achieving health equity by ensuring that resources are directed toward patients who need them most and reducing incentives to exclude or neglect high-risk patients. The authors reviewed available publications from PubMed and Google Scholar published between 2000 and 2025, as well as relevant news articles, policy documents, websites, and other sources related to risk adjustment and application areas. This process yielded 8 recommendations related to standardizing risk adjustment methods, promoting data interoperability, implementing strategies to enable more accurate and continuous reflections of patients' health status, integrating valid and reliable metrics into regular evaluation and feedback mechanisms, limiting "gaming" opportunities and incentives, creating valid ways to measure costs of caring for patients who are experiencing health care disparities and inequities and/or are disproportionately affected by social drivers of health, evaluating and leveraging advanced analytics and machine learning when able to improve risk adjustment models, and promoting research and implementation methods that combine elements of both prospective and concurrent risk adjustment. Implementation of these risk adjustment recommendations has broad implications for various entities in the health care ecosystem.

Climate change is anticipated to continue to adversely affect public health, with heat stress the predominant threat. Accordingly, heat-related illness is predicted to increase as extremely hot days become more frequent. Heat stroke, the most serious heat-related illness, is a medical emergency that may be fatal if it is not promptly recognized, addressed with early and rapid cooling, and accompanied by multidisciplinary supportive care as clinically indicated. Heat stroke is a preventable illness that occurs in 2 distinct forms-classic and exertional-that have distinct demographic profiles and clinical courses but similar management paradigms.

In January 2025, the Republican majority in the House of Representatives' Budget Committee offered a list of possible spending reductions to offset revenue losses from proposed tax cuts. In May, the Committee advanced a bill incorporating several reductions on the list. The Committee estimated that the 6 largest potential Medicaid cuts (for example, work requirements for some Medicaid enrollees) would each reduce the federal government's Medicaid outlays by at least $100 billion over 10 years. On the basis of the Committee's estimates of savings; Congressional Budget Office analyses; and peer-reviewed studies of the coverage, financial, and health impacts of past Medicaid expansions and contractions, the authors project the likely effects of each option and of the House bill advanced by the Budget Committee in May. Each option individually would reduce federal Medicaid outlays by between $100 billion and $900 billion over a decade, increase the ranks of the uninsured by between 600 000 and 3 900 000 and the annual number of persons forgoing needed medical care by 129 060 to 838 890, and result in 651 to 12 626 medically preventable deaths annually. Enactment of the House bill advanced in May would increase the number of uninsured persons by 7.6 million and the number of deaths by 16 642 annually, according to a mid-range estimate. These figures exclude harms from lowering provider payments and shrinking benefits, as well as possible repercussions from states increasing taxes or shifting expenditures from other needs to make up for shortfalls in federal Medicaid funding. Policy makers should weigh the likely health and financial harms to patients and providers of reducing Medicaid expenditures against the desirability of tax reductions, which would accrue mostly to wealthy Americans.

Type 1 and type 2 diabetes are prevalent chronic illnesses, are leading causes of mortality and morbidity, and result in substantial public health burden. Timely identification and appropriate management of diabetes can help reduce adverse consequences of diabetes. The American College of Physicians (ACP) embraces performance measurement as a means to improve quality of care but believes that a performance measure must be methodologically sound and evidence-based in order to be considered for inclusion in payment, accountability, or reporting programs. These principles are critical given the potential impact on physician administrative work, reputation, and reimbursement and to prevent unintended consequences for patient care. To help improve performance measurement and reduce burden, the ACP Performance Measurement Committee (PMC) reviews performance measures using a rigorous process to recognize high-quality measures and address gaps and areas for improvement. In this article, the PMC presents its review of 14 current performance measures for diabetes that are relevant to internal medicine. The PMC supports kidney health evaluation at the individual and group practice levels, hemoglobin A1c control at the health plan level, eye examination at the health plan level, and angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker therapy at the individual physician level.

More than 90 million women in the United States have given birth. Randomized controlled trials (RCTs) of medications almost always exclude pregnant participants.

People with disabilities are less likely than the general population to receive clinical preventive services.

Gout is characterized by deposition of monosodium urate (MSU) crystals in or around joints, tendons, bursae, and other tissues, resulting in painful recurrent flares and tissue damage. Gout is the most common form of inflammatory arthritis, with a prevalence of 5.1% in the United States, affecting 12.1 million adults. When urate levels exceed the limit of solubility (6.8 mg/dL [400 μmol/L]), MSU crystals may form or grow. Gout flares are the result of inflammatory responses to MSU crystals. The primary method to prevent and reduce gout flares, tophi, chronic inflammatory arthritis, and joint damage is to reduce urate levels below the saturation threshold. The pathophysiology of gout is well understood, and inexpensive and effective therapies are available. However, outcomes for patients with gout remain poorly optimized.
