Traditionally, lower extremity deep venous thrombosis (DVT) is diagnosed by radiology-performed venous duplex ultrasound. Providers appropriately trained in focused point-of-care ultrasound (POCUS) can perform a rapid bedside examination with high sensitivity and specificity in critically ill patients. We describe the scanning technique for focused POCUS DVT lower extremity examination.

2023
An interdisciplinary team includes many healthcare professionals working together and utilizing their skills, knowledge, and expertise to provide holistic and quality patient care. Physicians The physician's primary responsibility is to diagnose illness and direct the medical or surgical treatment of the condition. The authority to admit patients to a healthcare agency or institution and practice care within that setting is granted to physicians by the healthcare agency or institution itself.

FAQs
The main mechanism is time-saving access to a preliminary result. Because testing occurs near the patient, clinicians or other care providers can consider findings during the same visit. That timing can support early detection, triage, or a prompt referral or treatment decision, rather than waiting for information from a centralized laboratory.
A screening result is most useful when the test or measurement matches the health risk being assessed and its preliminary nature is recognized. The setting also matters: portable devices and simple examination methods can extend screening where centralized laboratory services are limited. Findings that suggest disease must enter an appropriate follow-up pathway.
The principal difference is where and when the initial assessment occurs. Point-of-care screening is performed close to the patient and often provides information during the same visit, whereas centralized laboratory testing is conducted away from the care setting. The near-patient approach emphasizes rapid access and immediate clinical context, not replacement of needed diagnostic evaluation.
A positive screening finding identifies a possible disease or health risk, but it generally requires appropriate follow-up. Confirmatory testing or a broader diagnostic evaluation may be needed before clinicians establish what the finding means for the patient. This distinction helps prevent a preliminary result from being interpreted as definitive evidence of disease.
A typical workflow begins by selecting an appropriate preliminary test, measurement, or simple examination method for the suspected health risk. The sample or clinical measurement is assessed near the patient with a portable device or rapid assay, and the result is reviewed during the visit. Depending on the finding, care may include referral, treatment, or confirmatory evaluation.
The approach can be used at the bedside, in clinics, pharmacies, or community settings. These locations bring preliminary assessment closer to people who may not have immediate access to centralized laboratory services. Using screening in such settings can improve access to care while allowing results to inform triage, referral, or other clinical decisions during the same visit.
It is especially useful when early identification, rapid triage, or timely referral matters. A near-patient result can help identify possible disease or health risks and support decisions about the next step in care. Its value is also important in settings with limited laboratory services, where portable devices, rapid assays, or simple examinations can broaden access to initial assessment.
