In the Clinic is a monthly feature in Annals of Internal Medicine introduced in January 2007 that focuses on practical management of patients with common clinical conditions. It offers evidence-based answers to frequently asked questions about screening, prevention, diagnosis, therapy, and patient education and provides physicians with tools to improve the quality of care. All ACP members and Annals subscribers have full access to this content.
Management of patients taking anticoagulants around the time of a procedure is a common and complex clinical scenario. Providing evidence-based care requires estimation of risk for thrombosis and bleeding, knowledge of commonly used medications, multidisciplinary communication and collaboration, and patient engagement and education. This review provides a standardized, evidence-based approach to periprocedural management of anticoagulation, based on current evidence and expert clinical guidelines.
Care of the Patient with Abnormal Kidney Test Results
Blood and urine tests are commonly performed by clinicians in both ambulatory and hospital settings that detect chronic and acute kidney disease. Thresholds for these tests have been established that signal the presence and severity of kidney injury or dysfunction. In the appropriate clinical context of a patient's history and physical examination, an abnormal test result should trigger specific actions for clinicians, including reviewing patient medication use, follow-up testing, prescribing lifestyle modifications, and specialist referral. Tests for kidney disease can also be used to determine the future risk for kidney failure as well as cardiovascular death.
