Introduction: Hospitalization is associated with acute changes in sarcopenia status in older people, but the influencing factors are not fully understood. Pre-admission care dependency level as a risk factor has not yet been investigated., Objective: Evaluate if pre-admission care dependency level is an independent predictor of sarcopenia changes following hospitalization., Setting and Subjects: Data came from the Sarcopenia 9+ EAMA Project, a European prospective multi-centre study. For this study, 227 hospitalised older people were included from four different hospitals in Belgium, Spain and Poland, between 18 February 2019 and 5 September 2020., Methods: Sarcopenia status at admission and discharge were calculated using a combined score (desirability value) based on muscle mass (calf circumference), strength (grip) and function (walking speed). Ratio of admission to discharge status was the outcome (desirability ratio; 1.00 meaning no difference). Predictor variable was the pre-admission care dependency level, classified into three groups: independent older people living at home, dependent older people living at home and older people living in a care home. Linear regression models were applied, considering potential confounders., Results: Mean desirability ratio for dependent older people living at home ('middle dependent group') was lower (0.89) compared to independent older people (0.98; regression coefficient -0.09 [95% CI -0.16, -0.02]) and care home patients (1.05; -0.16 [95% CI -0.01, -0.31]). Adjusting for potential confounders or using another statistical approach did not affect the main results., Conclusion: Dependent older people living at home were at higher risk of deterioration in sarcopenia status following hospitalization. In-depth studies investigating causes and potential interventions of these findings are needed., (© The Author(s) 2021.

Background: Sarcopenia is a potentially reversible condition, which requires proper screening and diagnosis., Aims: To validate a Polish version of sarcopenia screening questionnaire (SARC-F), and assess its clinical performance., Methods: Cross-sectional validation study in community-dwelling subjects ≥ 65 years of age. Diagnosis of sarcopenia was based on the 2018 2nd European Working Group on Sarcopenia in Older People (EWGSOP2) consensus. Hand grip and 4-m gait speed were measured, and the Polish version of SARC-F was administered., Results: The mean (SD) age of 73 participants (21.9% men) was 77.8 (7.3) years. Seventeen participants (23.3%) fulfilled the EWGSOP2 criteria of sarcopenia, and 9 (12.3%) criteria for severe sarcopenia. Fourteen (19.2%) participants fulfilled the SARC-F criteria for clinical suspicion of sarcopenia. The Cronbach's alpha coefficient for internal was 0.84. With EWGSOP2 sarcopenia as a gold standard, the sensitivity of SARC-F was 35.3% (95% CI 14.2-61.7, p = 0.33), specificity was 85.7% (95% CI 73.8-93.6, p < 0.0001). The corresponding positive and negative predictive values were 42.9% (p = 0.79) and 81.4% (p < 0.0001), respectively. The probability of false-positive result was 14.3% (95% CI 6.4-26.2, p < 0.0001) and the probability of false-negative result was 64.7% (95% CI 38.3-85.8, p = 0.33). Overall the predictive power of SARC-F was low (c-statistic 0.64)., Discussion: SARC-F is currently recommended for sarcopenia case finding in general population of older adults. However, its sensitivity is low, despite high specificity., Conclusions: At present SARC-F is better suited to rule out sarcopenia then to case-finding. Further refinement of screening for sarcopenia with the use of SARC-F seems needed.

Purpose: To estimate functional capability and attendant falls-risk in older institutionalized people after total hip arthroplasty (THA) for femoral neck fractures., Methods: The study population comprised 149 consecutive patients (F104, M45; mean age 83.4 years) who were permanent residents of nursing care facilities four weeks after THA for femoral neck fractures. Individual mental and functional capability status was assessed using the Mini Mental State Examination (MMSE), Timed Up and Go test (TUG) and Tinetti's Performance Oriented Mobility Assessment (POMA) which includes sub-scales for balance (B) and gait (G), in conjunction with identifying any concomitant disorders, reviewing individual pharmacotherapy and leisure time activities., Results: The subjects' mean MMSE was 23.1 points, whereas in Tinetti's POMA they scored 19 points on average, which translated into a five-fold greater falls-risk, whereas average TUG scores of 23.9s effectively corroborated this assertion. Multiple regression analysis effectively highlighted that TUG scores were strongly correlated with the actual number of concomitant disorders, number of regularly taken medications, and usual manner of spending leisure time., Conclusions: Institutionalized older people after THA for femoral neck fracture continue to be exposed to high risk of recurrent, possibly injurious falls, which is closely correlated with significantly diminished individual functional capabilities., (Copyright © 2015 Elsevier Ireland Ltd.
