Muscle ultrasound: Examine all patients both USG and Fraility scale

Study summary

Assessment of muscle mass in critically ill patients is critical for both improving clinical outcomes and monitoring the effectiveness of nutritional interventions. Loss of muscle mass is associated with mortality and morbidity in the elderly, including organ transplantation, trauma, and sepsis. Previous studies have assessed muscle mass using computed tomography. The use of computed tomography is costly, carries radiation risks, and requires the patient to be transported to a CT scanner. In contrast, ultrasonography is a noninvasive, rapid, and bedside method without radiation exposure. In particular, anterior thigh muscle thickness (ATMT) stands out as a reliable biomarker in the assessment of muscle mass. ATMT measurement includes the assessment of the combined depth of the vastus intermedius and rectus femoris muscles in the anterior thigh. There is no study in the literature examining the effects of anterior thigh muscle thickness measured by ultrasonography on malnutrition and frailty in intensive care patients. In this study, we aimed to investigate the effects of anterior thigh muscle thickness on frailty, malnutrition and length of stay in intensive care patients.

Eligibility

Primary outcome measure(s)

• Front Thigh Muscle Measurement — Ultrasound assessments will be performed within 24 hours of intensive care unit (ICU) admission and repeated on ICU days 3 and 7.
  Anterior thigh muscle thickness will be measured using ultrasonography with a linear transducer operating at 5-10 MHz. Using ample gel and minimal probe compression, the measurement site will be marked at the midpoint between the anterior superior iliac spine (SIAS) and the superior pole of the patella. Total quadriceps thickness-defined as the combined thickness of the rectus femoris and vastus intermedius-will then be recorded. Thickness will be measured as milimeter. Ultrasound assessments will be performed within 24 hours of intensive care unit (ICU) admission and repeated on ICU days 3 and 7.
• Frailty Assessment — Frailty will be ascertained at ICU admission by interviewing family/caregivers about the patient's frailty level prior to the acute illness and hospitalization.
  Frailty will be assessed using the Clinical Frailty Scale (CFS). Frailty status will be determined at the time of ICU admission by interviewing family members/caregivers to ascertain the patient's frailty level prior to the acute illness and hospitalization. Clinical Frailty Scale (CFS): 1 Very fit; 2 Well; 3 Managing well; 4 Vulnerable-independent but slowed, fatigued; 5 Mildly frail-needs help with instrumental ADLs (finances, transport, heavy housework, meds); 6 Moderately frail-needs help with all outside activities/housework; may need minimal help bathing/dressing; 7 Severely frail-dependent for personal care but clinically stable; 8 Very severely frail-dependent, near end of life; 9 Terminally ill-life expectancy \<6 months. Classification: 1-3 non-frail; 4 pre-frail; ≥5 frail
• Nutritional Status Assessment — Will be ascertained at ICU admission by interviewing with family/caregivers
  Assessment nutritional risk in ICU patients and identify those at high risk of malnutrition, the NRS-2002, GLIM criteria, and the NUTRIC score will be used. (NRS-2002: Nutritional Risk Screening 2002; GLIM: Global Leadership Initiative on Malnutrition; NUTRIC: Nutrition Risk in the Critically Ill.)
