Does This Patient Have Volume Overload? The Rational Clinical Examination

Objective: To identify the most accurate clinical examination, radiographic, and laboratory findings for assessing volume overload in nonintubated patients.

Data sources and study selection: MEDLINE was searched (1946 to January 6, 2026) to identify peer-reviewed English-language studies about the diagnostic accuracy of the clinical examination of spontaneously breathing patients with intravascular volume overload.

Data extraction and synthesis: Three authors independently extracted data for each finding and calculated sensitivity, specificity, and likelihood ratios (LRs). A 2-level mixed logistic regression model was used to pool estimates.

Results: Forty studies, involving 11 490 adult patients, were included, with a prevalence of volume overload of 35% to 69%. Thirty-three of those studies evaluated patients with dyspnea. Prevalence of volume overload was more likely when the physical examination revealed jugular venous distention with the highest point of pulsation more than 3 cm in a vertical line above the sternal angle (LR, 4.1 [95% CI, 2.9-5.6]; specificity, 92%), lower extremity edema (LR, 2.2 [95% CI, 1.5-3.1]; specificity, 80%), or crackles on auscultation (LR, 2.7 [95% CI, 1.7-4.5]; specificity, 81%). Vascular congestion on chest radiography increased the likelihood of intravascular volume overload (LR, 5.9 [95% CI, 2.9-12.0]; specificity, 91%). Point-of-care ultrasonography that identified bilateral pulmonary B-lines suggested volume overload (LR, 4.0 [95% CI, 2.6-6.1]; specificity, 77%), and absence of pulmonary B-lines made volume overload unlikely (LR, 0.09 [95% CI, 0.04-0.23]; sensitivity, 93%). Inferior vena cava collapsibility index of less than 50% increased the likelihood of volume overload (LR, 3.9 [95% CI, 2.5-6.1]; specificity, 79%), and a collapsibility index of at least 50% made it less likely (LR, 0.22 [95% CI, 0.11-0.45]; sensitivity, 82%). Point-of-care ultrasonographic measurement of jugular venous pressure (JVP; >8 cm) also increased the likelihood of volume overload (LR, 2.8 [95% CI, 2.2-3.5]; specificity, 71%), although JVP of 8 cm or less identified patients less likely to have volume overload (LR, 0.26 [95% CI, 0.20-0.33]; sensitivity, 81%). A plasma brain-type natriuretic peptide (BNP) level of 100 ng/mL or higher was the single best test to identify those most likely to have volume overload (LR, 6.9 [95% CI, 2.4-20.4]; specificity, 87%), and a normal value made it less likely (LR, 0.14 [95% CI, 0.08-0.24]; sensitivity, 87%).

Conclusions and relevance: A BNP level of 100 ng/mL or higher and presence of vascular congestion on chest radiography may be the most useful tests to identify patients with volume overload. Absence of pulmonary B-lines using point-of-care ultrasonography or BNP levels of less than 100 ng/mL may be most useful to exclude volume overload.

Abstract

The stethoscope has long been at the center of patient care as well as a symbol of the physician-patient relationship. While advancements in other diagnostic modalities have allowed for more efficient and accurate diagnosis, the stethoscope has evolved in parallel to address the needs of the modern era of medicine. These advancements include sound visualization, ambient noise reduction/cancellation, Bluetooth™ transmission, and computer algorithm diagnostic support. However, despite these advancements, the ever-changing climate of infection prevention, especially in the wake of the COVID-19 pandemic, has led many to question the stethoscope as a vector for infectious diseases. Stethoscopes have been reported to harbor bacteria with contamination levels comparable to a physician's hand. Although disinfection is recommended, stethoscope hygiene compliance remains low. In addition, disinfectants may not be completely effective in eliminating microorganisms. Despite these risks, the growing technological integration with the stethoscope continues to make it a highly valuable tool. Rather than casting our valuable tool and symbol of medicine aside, we must create and implement an effective method of stethoscope hygiene to keep patients safe.

•Stethoscopes are clinically valuable and integral to the doctor-patient connection

•Technological advancement will augment the utility of the stethoscope

•The stethoscope has high utility for assessment of COVID-19 patients

•Pathogen contamination in light of COVID-19 is a concern for the stethoscope

•Innovations in stethoscope hygiene will allow safe auscultation
