Effectiveness and organizational conditions of effectiveness of telemedicine in nursing homes. A study protocol of a comparative prospective cohort (EFFORT study)

The profile of nursing home (NH) residents has changed over the past decade with more dependency, more severe chronic diseases and more treatments prescribed. For residents, the major consequence is the higher risk of unplanned hospitalization. French guidelines recommend the development of interactive telemedicine (InT) in NHs in order to improve access to care, and to decrease the rate of avoidable unplanned hospitalizations.

Methods and analysis: The aim of this study is to analyze the impact of an InT protocol delivered in NHs on the rate of unplanned hospitalizations, and on the quality of life at work and the organizational conditions of effectiveness of telemedicine in NHs. We will perform a mixed methods study combining a cluster non-randomized controlled trial in two matched parallel arms (telemedicine group and control group) and qualitative analysis of the evolution of organizational and professional contexts in NHs.

Ethics and dissemination: The study protocol was approved and sponsored by the French Ministry of Health. The study received ethical approval from the Bordeaux University Hospital Institutional Review Board. We will communicate the final results to the public via conferences and results will also be submitted for publication in international peer-reviewed scientific journals.

Is the subcutaneous route an alternative for administering ertapenem to older patients? PHACINERTA study

BACKGROUND

Antibiotic administration by subcutaneous (SC) injection is common practice in French geriatric wards as an alternative to the intravenous (IV) route, but few pharmacokinetic/pharmacodynamic data are available. Ertapenem is useful for the treatment of infections with ESBL-producing enterobacteria.

OBJECTIVES

To report and compare ertapenem pharmacokinetic data between IV and SC routes in older persons.

METHODS

Patients >65 years of age receiving ertapenem (1 g once daily) for at least 48 h (IV or SC, steady-state) were prospectively enrolled. Total ertapenem concentrations [residual (C0), IV peak (C0.5) and SC peak (C2.5)] were determined by UV HPLC. Individual-predicted AUC0-24 values were calculated and population pharmacokinetic analyses were performed. Using the final model, a Monte Carlo simulation involving 10 000 patients evaluated the influence of SC or IV administration on the PTA. Tolerance to ertapenem and recovery were also monitored. ClinicalTrials.gov identifier: NCT02505386.

RESULTS

Ten (mean ± SD age=87±7 years) and 16 (age=88±5 years) patients were included in the IV and SC groups, respectively. The mean C0 and C2.5 values were not significantly different between the IV and SC groups (C0=12±5.9 versus 12±7.4 mg/L, P=0.97; C2.5=97±42 versus 67±41 mg/L, P=0.99). The mean C0.5 was higher in the IV group compared with the SC group (C0.5=184±90 versus 51±66 mg/L, P=0.001). The mean individual AUCs (1126.92±334.99 mg·h/L for IV versus 1005.3±266.0 mg·h/L for SC, P=0.38) and PTAs were not significantly different between groups. No severe antibiotic-related adverse effects were noted.

CONCLUSIONS

SC administration of ertapenem is an alternative to IV administration in older patients.

Quality of Life: Psychological Symptoms-Effects of a 2-Month Healthy Diet and Nutraceutical Intervention; A Randomized, Open-Label Intervention Trial (RISTOMED)

Depression symptoms and lower health-related quality of life (HRQoL) are associated with inflammation. This multicenter dietary intervention was shown to reduce inflammation in older people. This was the main outcome. Here, we describe the effects on HRQoL, anxiety, and depressive symptoms according to inflammation status. Overall, 125 healthy older subjects (65–80 year) were recruited (Italy, France, and Germany) and randomized into four arms (A, Healthy diet (HD); B, HD plus De Simone Formulation probiotic blend; C, HD plus AISA d-Limonene; D, HD plus Argan oil). The HD was weight maintaining, rich in antioxidant vitamins, polyphenols, polyunsaturated fatty acids (n6: n3 ratio = 3:1), and fiber. Data on inflammatory parameters, mental (MCS) and physical (PCS) component summaries of HRQoL (SF−36), anxiety symptoms (STAI state), and depressive symptoms (CES-D) were collected before and after 56 days of intervention. Body fat mass proportion (BFM) was considered a co-variable. A decrease of CES-D score was seen in the four arms (A: −40.0%, p = 0.001; B: −32.5%, p = 0.023; C: −42.8%, p = 0.004; and D: −33.3%, p = 0.21). Within the subgroups of subjects with medium/high inflammation a similar decrease in CES-D score occurred in all groups (A: −44.8%, p = 0.021; B, −46.7%, p = 0.024; C, −52.2%, p = 0.039; D, −43.8%, p = 0.037). The effect of interventions on CES-D was not related to baseline inflammation. MCS-HRQoL improved in A and C. There was no change in anxiety or PCS-HRQoL. In this trial with no control group, a decrease in depressive symptoms in healthy older volunteers was observed after a 2-month healthy diet intervention, independently of inflammation but with possible limitations due to participation.

Effects of a physical activity programme to prevent physical performance decline in onco-geriatric patients: a randomized multicentre trial

BACKGROUND

Older adults with cancer experience negative long-term functional effects of both cancer and treatments. Exercise may minimize their age-related and cancer-related functional decline.

METHODS

We conducted a multicentre open-label 12 month randomized clinical trial with two parallel arms including participants aged ≥70 years with lymphoma or carcinoma requiring curative treatment. The study started at the beginning of any phase of cancer treatment (surgery, chemotherapy, or radiotherapy). The usual care group (UCG) received the current national recommendations in physical activity (a guideline without specific counselling). The intervention group (IG) received 1 year phoned physical activity advice individually adapted to physical assessment (twice a month during the first 6 months and then monthly). The primary outcome was the proportion of subjects with a 1 year decreased short physical performance battery (SPPB) score of 1 point or more. Physical, cognitive, and clinical secondary outcomes were also investigated.

RESULTS

We allocated 301 participants (age 76.7 ± 5.0, female 60.6%) to each group. At baseline, the median SPPB was 10/12 in both groups. Breast was the most frequent tumour site (35.7%). After 1 year, 14.0% of participants in the UCG and 18.7% in the IG had a decrease in SPPB score of 1 point or more (P = 0.772). At 2 years, there was no difference in SPPB, gait speed, International Physical Activity Questionnaire score, and verbal fluency. Subgroup analyses after 2 years showed a decline in SPPB for 29.8% of UCG and 5.0% of IG breast cancer participants (P = 0.006), in 21.7% of UCG and 6.2% of IG female participants (P = 0.019), and in 24.5% of UCG and 11.1% of IG normal nutritional status participants (P = 0.009). Falls, hospitalization, institutionalization, and death rates were similar in both groups.

CONCLUSIONS

Personalized phoned physical activity advice had not reduced functional decline at 1 year but provided preliminary evidence that may prevent physical performance decline at 2 years in older adults with breast cancer.

Design of a Physical Activity Program to Prevent Functional Decline in Onco-Geriatric Patients (CAPADOGE): A Randomized Multicenter Trial

BACKGROUND

Cancer in older patient favours the development of frailty: feeling of exhaustion, loss of weight, decreased muscle strength, slow gait speed, and low physical activity.

OBJECTIVES

To evaluate the efficacy of adapted physical activity phone advices in limiting the cancer-induced loss of autonomy and frailty phenotype development.

DESIGN

Multicenter randomized controlled trial.

SETTING

Patients (>70y) undergoing curative treatment for cancer (n=400) will be recruited from 12 centres.

INTERVENTION

The intervention consists in phoned personalized physical activity advices related to strength, aerobic, balance, proprioception, and flexibility. The contacts are performed twice a month during six months and then monthly until 1 year. The intervention complements the PNNS booklet advices (National Nutritional Health Program). The trial compares «individualized phone advices + PNNS» to «usual care + PNNS».

MEASUREMENTS

Functional, cognitive, clinical and self-reported data are assessed before treatment and at 3, 6, 12, 18, and 24 month follow-up. The primary outcome is the proportion of subjects with a one-year decreased SPPB (Short Physical Performance Battery) score of one point or more, as compared to baseline. The secondary outcomes include quality of life items, rate of hospitalizations, institutionalizations, mortality, Fried phenotype at 1 and 2 years, and the SPPB score at 2 years.

DISCUSSION

This large trial will provide clinical data of the effects of an exercise advices intervention in older patients during cancer therapy on function and cognition evolution, and quality of life. The possibilities of minimizing the development of frailty phenotype due to these advices will be explored.

Impact of personalized diet and probiotic supplementation on inflammation, nutritional parameters and intestinal microbiota - The "RISTOMED project": Randomized controlled trial in healthy older people

OBJECTIVES

To assess the impact of a personalized diet, with or without addition of VSL#3 preparation, on biomarkers of inflammation, nutrition, oxidative stress and intestinal microbiota in 62 healthy persons aged 65-85 years.

DESIGN

Open label, randomized, multicenter study.

PRIMARY ENDPOINT

High-sensitivity C-reactive protein.

SETTING

Community.

INTERVENTIONS

Eight week web-based dietary advice (RISTOMED platform) alone or with supplementation of VSL#3 (2 capsules per day). The RISTOMED diet was optimized to reduce inflammation and oxidative stress.

MEASUREMENTS

Blood and stool samples were collected on days 1 and 56.

RESULTS

Diet alone reduced ESR (p = 0.02), plasma levels of cholesterol (p < 0.01) and glucose (p = 0.03). Addition of VSL#3 reduced ESR (p = 0.05) and improved folate (p = 0.007), vitamin B12 (p = 0.001) and homocysteine (p < 0.001) plasma levels. Neither intervention demonstrated any further effects on inflammation. Subgroup analysis showed 40 participants without signs of low-grade inflammation (hsCRP<3 mg/l, subgroup 1) and 21 participants with low-grade inflammation at baseline (hsCRP≥3 mg/l, subgroup 2). In subgroup 2 addition of VSL#3 increased bifidobacteria (p = 0.005) in more participants and improved both folate (p = 0.015) and vitamin B12 (p = 0.035) levels compared with subgroup 1. The increases were positively correlated to the change in the bifidobacteria concentration for folate (p = 0.023) and vitamin B12 (p = 0.001). As expected change in homocysteine correlated negatively to change in folate (r = -0.629, p = 0.002) and vitamin B12 (r = -0.482, p = 0.026).

CONCLUSIONS

Addition of VSL#3 increased bifidobacteria and supported adequate folate and vitamin B12 concentrations in subjects with low-grade inflammation. Decrease in homocysteine with VSL#3 was clinically relevant. suggesting protective potentials for aging-associated conditions, e.g. cardiovascular or neurological diseases.

Air displacement plethysmography can detect moderate changes in body composition

OBJECTIVES

To determine the sensitivity of air displacement plethysmography (APD) for evaluation of changes in body composition in normal subjects.

DESIGN

Comparison of measurements with and without oil or water loads.

SUBJECTS AND METHODS

Ten healthy volunteers were analyzed, without and with 1 l and 2 l of oil or water. The measured and true changes in fat mass and fat-free mass were compared by paired t-tests. A correlation study and a Bland & Altman procedure was performed on the 60 measurements of adiposity changes in 30 subjects carrying 0.5 l (n=8 x 2), 1 l (n=10 x 2) and 2 l (n=12 x 2) oil and water loads.

RESULTS

Fat-free mass increased when the 10 subjects were carrying water. When they carried oil, fat mass increased, however, a approximately 0.5 kg increase of fat-free mass was also detected. Two liters loads led to distinct changes: +1.49+/-0.59 kg fat and +0.50+/-0.60 kg fat-free with oil and +0.37+/-0.57 kg fat and +1.70+/-0.56 kg fat-free with water (both P<0.001). Mixed loads (+1 l oil and 1 l water) led to detect +0.85+/-0.48 kg fat and +1.09+/-0.45 kg fat-free (both P<0.005 vs without load). For the 30 subjects analyzed thrice, measured changes in fat and fat-free mass were slightly underestimated (-15%, NS) but correlated with the true changes. Measured changes in adiposity were correlated with the true changes, with no bias as indicated by the Bland & Altman procedure.

CONCLUSION

APD detects approximately 2 kg changes in fat or fat-free mass in small populations.
