Does the Integration of Personalized Ultrasound Change Patient Management in Critical Care Medicine? Observational Trials

Table 1

Types of indications for application of a mobile ultrasound device (MobUS) in comparison to a randomized availability of a personalized ultrasound device (PersUS). 𝑁=101 patients were examined (33 exams with MobUS, 68 with PersUS) with a total of 167 indications and ultrasound studies.

Category number	Kind of indication	𝑁 (% of total); MobUS studies	Time (min); Mean ± SD	𝑁 (% of total); PersUS studies	Time (min); Mean ± SD	Percentage; change (%)
1	Cardiac function (visual LVEF, eyeballing)	15 (9)	4.8±1.1	36 (22)	4.4±1.0	114
2	Focused cardiac anatomy and valve assessment	14 (9)	4.7±1.1	27 (17)	4.5±1.0	93
3	Dyspnoea, suspected pleural effusions	7 (4)	14.1±9.9	24 (14)	9.2±4.8	243
4	Pericardial effusion	4 (2)	4.8±2.2	14 (9)	4.4±0.9	250
5	Abdomen/ascites	3 (2)	21.7±7.6	8 (4)	9.9±5.5	166
6	Ultrasound-guided punctures	2 (1)	20±0	5 (3)	12.0±4.5	150
7	Miscellaneous (a)	1 (1)	10±0	2 (1)	4.5±0.7	100
8	Resuscitation	3 (2)	4.0±1.0	1 (1)	4.0±0	n.a.
	Total (167, 100%)	49 (29)	8.2±7.0	118 (71)	6.5±3.9	141

(a) Including groin aneurysm spurium and cubital vein detection for puncture.
n.a.: not applicable. All times as estimated by the examiner from beginning (hands-on) to end (hands-off) of the examination procedure. Descriptive data presentation only. Percentage change was calculated as (the number of PersUS studies minus the number of MobUS studies) divided by the number of MobUS studies.
