BMC Geriatr 2020 08 18;20(1):295. Epub 2020 Aug 18.

Department of Geriatrics, Poitiers University Hospital, Poitiers, France.

Background: Older patients with cancer require specific and individualized management. The 3-group Multidimensional Prognostic Index (MPI) based on the Comprehensive Geriatric Assessment (CGA) has shown a predictive interest in terms of mortality. The objective of our study was to assess the prognostic value of MPI for 1-year mortality in an external prospective French cohort of elderly patients with cancer.

Methods: From March 2015 to March 2017 a prospective single-center cohort study enrolled all patients with cancer, aged 75 years and older referred to the geriatric oncology clinic. We used a proportional hazard model for 1-year mortality adjusted for age, sex, tumor sites and metastatic status. C-statistics were used to assess the incremental predictive value of MPI index to these risk factors.

Results: overall, 433 patients underwent CGA with MPI (women 42%; mean age 82.8 ± 4.8 years). The most common tumor sites were prostate (23%), skin (17%), colorectum (15%) and breast (12%); 29% of patients had a metastatic disease; 231 patients (53%) belonged to the "MPI-1" group, 172 (40%) to the "MPI-2" group and 30 patients were classified in the "MPI-3" group. One-year mortality rate was 32% (23% in MPI-1, 41% in MPI-2 and 53% in MPI-3, p = 0.024). All domains of MPI except cognition and living status were significantly associated with mortality at one-year, as well as tumor sites and metastatic status. Higher MPI was associated with a higher mortality risk (adjusted HR 1.56 [95%CI 1.70-2.09] and 1.72 [1.33-2.22] for MPI groups 2 and 3 compared to 1; p < 0.0001).

Conclusions: In addition to established risk factors, MPI improves risk prediction of 1-year mortality. This practical prognostic tool may help to optimize management of these vulnerable patients.

Background: Elderly patients are often underrepresented in implantable cardioverter defibrillator (ICD) trials, and ICD implantation in patients ≥75 years consequently remains controversial. We aimed to evaluate mortality, appropriate ICD therapy rates and survival gain in an elderly population after risk stratification according to the Charlson Comorbidity Index (CCI).

Methods: This monocentric retrospective study included elderly ICD patients ≥75 years. They were subdivided according to their CCI score into 3 categories (0-1, 2-3 or ≥4 points). Elderly patients were matched 1:2 with younger control ICD patients on gender, type of prevention (primary or secondary) and type of device (associated cardiac resynchronization therapy or not).

Results: Between January 2009 and July 2017, 121 elderly patients (mean age 78 ± 3; 83% male) matched with 242 controls (mean age 66 ± 5) were included. At 5 year follow-up after ICD implantation, overall survival was 78%, 57%, and 29% (P = 0.002) in the elderly with a CCI score of 0-1, 2-3 and ≥4 respectively, and 72% in controls. There was no significant difference regarding ICD appropriate therapy between the 3 subgroups despite a trend towards lower rates of therapy in CCI ≥ 4 points patients (34.2%, 39.7% and 22.8% respectively; P = 0.45). Median potential survival gain after an appropriate therapy was >5, 4.7 and 1.4 years, with a CCI score of 0-1, 2-3 and ≥4 respectively (P = 0.01).

Conclusion: Elderly patients with CCI score ≥ 4 had the lowest survival after ICD implantation and little survival gain in case of appropriate defibrillator therapy. More than age alone, the burden of comorbidities assessed by the CCI could be helpful to better select elderly patients for ICD implantation.

[Interest of the multidimensional prognostic index (MPI) as an assessment tool in hospitalized patients in geriatrics].

Geriatr Psychol Neuropsychiatr Vieil 2019 12;17(4):386-392

The collection of prognostic information in the elderly is essential. The main objective was to perform a replication of the multidimensional prognostic index (MPI), to predict mortality at one-year in patients hospitalized in geriatric wards. Secondary objectives were to evaluate if the MPI was predictive of the length of hospital stay, and of rehospitalization in the following year.

Methods: Prospective study conducted from February 2015 to November 2016 at the University Hospital of Poitiers (Geriatrics department). A comprehensive geriatric assessment (number of treatment, lifestyle, autonomy, comorbidities, risk of pressure sore, nutritional and cognitive status) was used to calculate the MPI score and to categorize patients into three groups: low (MPI-1), moderate (MPI-2) and high (MPI-3) risk of mortality.

Results: 153 patients were included, with mean age 85.9 ± 5.4 years. Twenty-one patients (13.7%) belonged to MPI-1 group, 98 (64.1%) to MPI-2 group, and 34 (22.2%) to MPI-3 group. The number of deaths at one-year according to the MPI group was different (p < 0.01). The one-year prognostic performance of MPI was good (AUC at 0.76). MPI was also predictive of hospital length stay (p < 0.05).

Conclusion: MPI appears to be a relevant prognostic tool in the stratification of one-year mortality risk in elderly patients hospitalized in geriatrics.

Using a multidimensional prognostic index (MPI) based on comprehensive geriatric assessment (CGA) to predict mortality in elderly undergoing transcatheter aortic valve implantation.

Int J Cardiol 2017 Jun 16;236:381-386. Epub 2017 Feb 16.

Pôle de Gériatrie, Centre Hospitalier Universitaire de Poitiers, Université de Poitiers, Poitiers, France; INSERM, CIC-P 1402, Centre Hospitalier Universitaire de Poitiers, Université de Poitiers, Poitiers, France.

Background: Selection of appropriate elderly who can benefit from transcatheter aortic valve implantation (TAVI) is challenging. We evaluated the prognosis of this procedure according to the comprehensive geriatric assessment (CGA) based on the multidimensional prognostic index (MPI).

Methods: Prospective observational monocentric study from January 2013 to December 2015. Consecutive patients aged ≥75 who underwent TAVI and a complete CGA were included. Baseline demographic, geriatric and cardiologic data were collected. CGA was used to calculate the MPI score that is divided in three groups according to the mortality risk. Follow up was performed until December 2016 and mortality rate was assessed at one, six and 12months.

Results: 116 patients were included. Mean age was 86.2±4.2years, mean European system for cardiac operative risk evaluation (EuroSCORE) was 19.2±11.3%, mean MPI score was 0.39±0.13. Forty-five (38.8%) patients belonged to MPI-1 group, 68 (58.6%) to MPI-2 group and three to MPI-3 group. MPI score and Euroscore were moderately correlated (Spearman correlation coefficient r=0.27, p=0.0035). Mortality rate was significantly different between MPI groups at six and 12months (p=0.040 and p=0.022). Kaplan Meier survival estimates at one year stratified by MPI groups was significantly different (hazard ratio HR=2.83, 95%confidence interval (CI) 1.38-5.82, p=0.004). Among variables retained to perform logistic regression analysis, the score of instrumental activities of daily living appeared the most relevant (p<0.001).

Conclusion: This study indicates that CGA based on MPI tool is accurate to predict prognosis in elderly patients undergoing TAVI procedure.

Factors associated with orthostatic hypotension in hospitalized elderly patients.

Aging Clin Exp Res 2016 Jun 19;28(3):513-7. Epub 2015 Oct 19.

Pôle de Gériatrie, CHU La Milétrie, 86021, Poitiers Cedex, France.

Objective: To assess the factors associated with orthostatic hypotension (OH) in hospitalized elderly patients.

Design: Prospective observational single center study.

Setting: A French academic center.

Participants: One hundred and thirty-one patients without OH symptoms who underwent OH testing.

Measurements: The OH test was performed when the patient was able to get out of the bed and was no longer receiving parenteral fluids. The blood pressure was measured after a 10-min rest while the patients were sitting and then standing at 1 and 3 min. Demographic data, co-morbidities, current medications and biological parameters were recorded.

Results: The mean patient age was 84.3 ± 7 years. The mean CIRS-G score was 10.6 ± 3.8. The OH test was performed 6.3 ± 3.9 days after admission and was positive in 39 (29.8 %) patients (95 % confidence interval (CI) 22, 38) and positive at 1 min in 87.2 % of the cases. Multivariate analysis showed that OH prevalence correlated with diabetes (odds ratio (OR) = 4.23; 95 % CI 1.10, 16.24; P = 0.03), serum 25-hydroxyvitamin D <20 ng/ml (OR = 3.38; 95 % CI 1.36, 8.42; P = 0.008), use of tranquilizers (anxiolytic and hypnotic) (OR = 2.96; 95 % CI 1.18, 7.4; P = 0.02), CIRS-G score (OR = 1.15; 95 % CI 1.01, 1.31; P = 0.03) and lack of diuretics (OR = 0.20; 95 % CI 0.06, 0.63; P = 0.005).

Conclusion: In older adults, OH is often misdiagnosed because it is asymptomatic. As practitioners may be reluctant to perform the OH test because of time constraints, targeting a subgroup of patients with a higher risk of OH should be worthwhile to prevent further OH complications.

[Decisional algorithm to prescribe vitamin K antagonist in geriatric patients with atrial fibrillation].

Geriatr Psychol Neuropsychiatr Vieil 2014 Mar;12(1):20-4

Pôle de gériatrie.

Preventing atrial fibrillation (AF) complications relies mainly on anticoagulant therapy. Still it is difficult to prescribe vitamin K antagonists (VKA) in geriatric patients with AF. In order to improve anticoagulation decision in this disease, we set up an algorithm. Charts of all patients with AF hospitalized between February and May 2012 were reviewed. Patients treated with anticoagulation for another indication (venous thromboembolism disease, prosthetic valve) were excluded. Algorithm was built-up with 6 criteria (past bleeding with VKA, autonomy (GIR score), MMSE score, risk of falls, co-morbidities index). Each criterion had a score (0, 0.5, 1 point) according to an intensity scale (light, moderate, high). The final algorithm composite score led to the prescription or not of VKA. Patients were followed-up during 6 months after discharge. One hundred and fifty-three patients were included, mean age 86.1 ± 5.6 years; 67.3% had a GIR score ≤3, 70.6% MMSE score < 23, and 83.7% a moderate risk of falls. According to the algorithm, 92 patients (60.1%) had a VKA prescription. Prescription was significantly less prescribed in the oldest old (p=0.02). Follow-up showed 4 bleeding events without any link with VKA prescription. Thirty-four patients died (22.2%), among 24 (34.4%) who did not have VKA (p=0.005). The algorithm improves VKA prescription according to an objective evaluation and probably prevents the prescription in the patients with the worse short term prognosis.
