were only associated with lower mortality in the first model (HR 0.5,
p-value <0.001). In the second model, there was a tendency (HR 0.7,
p-value 0.085). There was no association in the third model in both
genders.
Conclusion: In elderly people, hemoglobin cannot be used as an
independent risk factor for mortality.

Plaza, E. Sánchez-García, A. Cruz-Jentoft. Hosp. Ramón y Cajal
Introduction: The presence of delirium in patients undergoing hip
fracture is common and this is also true with malnutrition. It seems
important to evaluate the association between MNA and perioperative
delirium in patients undergoing hip fracture.
Method: All patients ≥80 years admitted in the Orthogeriatric Unit of
a tertiary hospital and underwent hip surgery from June 2014 to June
2015 were included. Epidemiologic variables were collected, compre-
hensive geriatric assessment: Barthel index (BI), cognitive status,
visual and hearing deficit, nutritional status, presence of perioperative
delirium, basal location and drugs previously taken. Surgical risk was
classified by the American Society of Anaesthesiologists Index (ASA).
About the type of fracture and anaesthesia, the no authorization
of weight bearing, the mean stay and the hospital mortality were
collected.
Results: 362 patients were included, 33% with dementia, 56% without
visual deficit and 45% without hearing deficit. The 71% was taking
more tan 4 drugs. The 52% had ASA III, 51% pertrochanteric fracture
and the 94% spinal anaesthesia was used. Weight bearing was
not authorized in 8%. The mean stay was 14 ± 6 days and there was
hospital mortality of 4%. A 63% had a MNA < 12. A 44% developed a
perioperative delirium. The MNA <12 values were associated with the
presence of perioperative delirium (p = 0,002). This association
remained after the adjustment for age, gender and the presence of
dementia (p < 0,05).
Conclusions: The risk of malnutrition assessed by the MNA is
associated with the development of perioperative delirium in patients
older than 80 who underwent hip fracture surgery.

Introduction-objective: The Basque “Elderly Care Program” (PAM) is
developed based on a multidimensional geriatric assessment, focused
on a predominant preventive and functional component. Elderly
typologies and frailty are defined regarding their functionality [1–3].
The study objective is to analyse the prevalence of frailty and factors
and conditions associated with this state.
Methods: Transversal study in Primary Care, based on data from the
PAMpilot study. It included community dwelling people aged ≥70; the
study being approved by the Ethics Committee of Euskadi.
Considering the most unfavourable situation (50%), an accuracy and
degree of confidence of 5%, a sample of 377 subjects was needed. A
total of 666 persons was assessed, 569 had the typology stablished.
Typologies were defined, considering functionality (iADL Lawton-
Brody index; bADL Barthel index), existence of relevant chronic
diseases, and life expectancy <6 months, in: “healthy”, “with chronic
disease/s without important functional impairment”, “frail ” (iADL
Lawton alteration, Barthel >59, without terminal state), “dependent”,
“at the end of life ”. Other variables were associated, statistical signi-
ficance p = 0.05.
Results: A 19.2% (95% CI 16.1–22.6) was frail, women 21.2% (17.2 –25.9),
men 16.1% (11.9– 21.4), p 0.125. Frailty was associated -p < 0.001-
with age (32.1% in aged >80 vs 10.7% in aged 70–80), physical activity
(42.1% actives vs 76.7% non-actives), number of chronic medications
(mediane 8 -IQR 5-13- in frail people vs 13-8-17- in non-frail). Without
statistical association with gender, BMI, social support. Bone/osteo-
arthritis and cardiovascular diseases are significantly higher in frail
people.
Conclusions: Frailty is a common syndrome in dwelling elderly
people, associated with factors such as older age, increased activity,
bone/osteoarthritis and cardiovascular diseases, and they take many
medications although less than in non-fragile.

Introduction: Hand grip strength is a useful measure of functional
capacity in older people. It has predictive value for several outcomes.
Hydraulic Jamar® dynamometer (HJD) is the gold standard and the
most used instrument, but there is increasing interest in digital
instruments. Our aimwas to know the validity and reliability of DynX®
digital dynamometer (DDD) compared with HJD.
Objective: (1) To test the precision of both dynamometers. (2) To
compare the reliability among the two dynamometers in a series of
patients.
Methods: (1) Measurements were taken of several known weights
(every 5 Kg, from 5 to 40). (2) Grip strength testing was conducted
on 100 older patients hospitalised in geriatric acute wards. Pearson
correlations, intraclass correlation coefficient (ICC) and repeatability
coefficients and paried t test were used.
Results: (1) Both dynamometers showed excellent correlations with
known weigths (R2 = 0.999 for DDD, and R2 = 0.997 for HJD). (2)
Ninety four of 100 patients were able to complete the tests. Mean age
was 87.2(±5.9) years, 71% were women. There were no differences
among the first and the second test with each dynamometer
(ICC = 0.96 (CI95%: 0.95– 0.98) and ICC = 0.97 (CI95%: 0.95–0.98)
respectively. Significant differences were found between mean grip
scores obtained on the DDD (12 ± 5.5 Kg) and the HJD (14.5 ± 6.1 Kg)
(2.62 Kg, (IC95%: 2.04 to 3.21, p < 0.001).
Conclusions: Both tested dynamometer correlated well with known
weigths. Most hospitalised older patients were able to complete the
tests. HJD exhibited higher strength readings than DDD.
