Introduction:
SARC-F (Strength, Assistance in walking, Rise from a chair, Climb stairs and Falls) is a validated screening questionnaire for rapidly assessing sarcopenia in older adults with a variety of diseases while the Rockwood clinical frailty scale (RCFS) is a commonly used tool for assessing frailty in older adults. However, there are no data regarding the use of these tools in patients with type two intestinal failure (T2IF). We aimed to compare SARC-F and RCFS to bioelectrical impedance analysis (BIA) and anthropometry in patients with T2IF.
Methods:
In this cross-sectional study, patients with T2IF admitted to a national U.K. reference centre had SARC-F, RCFS, BIA and anthropometry performed. A SARC-F score ≥4 indicated potential sarcopenia while a RCFS ≥5 indicated frailty. Statistical analyses were conducted to assess correlation, concordance and differences between measurements.
Results:
The study comprised 76 patients, of whom 59.2 % were female, with a mean age of 56.5 years ± 16. Seventy percent of patients had short bowel syndrome as an underlying cause of IF. Thirty eight percent of patients had a SARC-F ≥4 and 20 % had a RCFS ≥5. SARC-F was correlated with RCFS (rs 0.43, p < 0.001), phase angle (PA) (rs -0.55, p < 0.001) and hand grip strength (HGS) (rs -0.34, p 0.004). RCFS was correlated with HGS (rs -0.31, p 0.009). Significant differences emerged between PA (p 0.002) and HGS (p 0.003) values in patients with SARC-F scores ≥4 and < 4 and with HGS for patients with RCFS ≥5 and < 5 (p 0.01). Patients with SARC-F scores ≥4 had longer lengths of stays than those with scores <4 (p 0.002). Compared to PA and HGS, SARC-F had sensitivities of 39 % and 37 % and specificities of 92 % and 73 % respectively.
Conclusion:
We demonstrated SARC-F is correlated with PA and HGS with comparable sensitivity and specificity to its original use in older individuals. There is a role for SARC-F as a means of rapidly assessing muscle quality and function in hospitalised patients with IF with RCFS providing some useful information about muscle function.
