Wrist Actigraphy: A Simple Way to Record Motor Activity in Elderly Patients with Dementia and Apathy or Aberrant Motor Behavior.

INTRODUCTION: In dementia, behavioral psychological symptoms are frequent and variable. OBJECTIVE: To assess the value of wrist actigraphy as a measure of disorder in motor behavior especially apathy, aberrant motor behavior, agitation and anxiety. METHODS: Cross sectional observational study of consecutive patients older than 75 years admitted to an intermediate care unit of a geriatric hospital ward during a two-year period. Psycho behavioral symptoms and cognitive status were assessed using the NPI scale and MMSE and diagnosis of dementia was done using DSMIV criteria. A wrist actigraph was worn for 10 days to record motor activity, sleep time and number of periods of sleep. RESULTS: 183 patients were included. Among patients with dementia, a significant decrease in motor activity was recorded in those with apathy from 9h to 12h and 18h to 21h (p <0.05) and in those with anxiety from 21h to 24h (p <0.05). Aberrant motor behavior in dementia was associated with a significant increase in motor activity from 21h to 24h (p <0.01). Agitation was not associated with a significant differences in motor activity. CONCLUSIONS: Wrist actigraphy can be used to record motor activity in elderly patients with dementia especially in those with apathy and aberrant motor behavior.

[Therapeutic education of elderly patients under antivitamin - K treatment: evaluation of the program after 5 years]. / Education thérapeutique de patients âges traités par AVK. Biltan d'un programme après 5 années d'existence.

INTRODUCTION: Elderly people with vitamin K antagonists (VKA) have a higher risk of potentially serious hemorrhagic complications. An education program for patients (EPP) aged > or = 75 years with VKA was set up in 2008 in a French geriatric hospital. It includes individual and group sessions conducted by a nurse and a geriatrician. OBJECTIVES: The aim of this study was to assess this EPP after 5 years. Strengths, weaknesses and difficulties of implementation were highlighted, and some improvements were proposed. METHODS: This study is an external audit conducted by a pharmacist trained in EPP. Files of consecutive patients included in the program between may 2008 and March 2013 were reviewed allowing the data collection of patients characteristics and results of the different sessions. The educational objectives were assessed by the rate of correct responses to the questionnaires during the program. The results are presented taking into account the changes made during the 5 years of the program. RESULTS: One hundred forty-three patients, mean age 83.3 +/- 6.5 years, were included in the EPP. 51 sessions were conducted (2.8 patients/session on average). 58% of selected patients were hospitalized. The mean time between the start of anticoagulant treatment and the incLusion in the program was 48.9 +/- 71 months. For 95 patients (66.4%) the medication management at home required a caregiver who was present for sessions in 82 cases (57.3%). The questionnaires form and the organisation of the sessions were gradually improved between 2008 and the end of 2010. Thus, the impact of the EPP has been estimated from November 2010 to March 2013. The correct responses rates before and after the sessions were respectively: 47.8% vs 91.3% for knowledge of INR target values, 25.4% vs 91.3% for knowledge of hemorrhagic signs, 14.9% vs 87.0% for knowledge of the situations or the medications that may disturb the INR equilibrium. Furthermore, the mean number of correct responses, for the 23 patients participating in the entire program, is statistically different between the educational diagnostic and immediate evaluation (3.7/7 vs 5.4/7 p = 0.023) and no significant difference is observed between immediate and distant evaluation (5.4/7 vs 5.8/7 p = 0.720). CONCLUSION: An improvement of patient knowledge was observed with regard to the main educational objectives. Some improvements are proposed: to disseminate information to general practitioners, to add the follow up of INR values to assess an impact on anticoagulant treatment stability. Furthermore, this program is now adapted to the new oral anticoagulants. It is the role of hospital or community pharmacists to initiate and/or assess this type of EPP.

Delirium in older people after proximal femoral fracture repair: role of a preoperative screening cognitive test.

OBJECTIVE: Preoperative cognitive impairment has been identified as a major risk factor for postoperative delirium in older people. The aim of this study was to evaluate whether a validated and rapid screening cognitive test - COgnitive Disorder EXamination (CODEX) - performed preoperatively before proximal femoral fracture repair, was associated with a risk of postoperative delirium. STUDY DESIGN: We performed an observational prospective cohort study in orthopedic surgery department of a French hospital. PATIENTS: We included patients aged 70years or older undergoing proximal femoral fracture repair and who were free of known dementia and delirium at the preoperative phase. METHODS: Before surgery, the anesthesiologist realized the CODEX based on three-word recall test, simplified clock drawing and if one of these tasks was abnormal, spatial orientation was assessed. Delirium was routinely sought on postoperative day 3 (D3) using the Confusion Assessment Method by the geriatrician. RESULTS: Among the 52 included patients, seven (13.5%) had delirium on D3. All seven patients were among the 25 patients with abnormal CODEX results. None of the 27 patients with normal CODEX results had postoperative delirium. Abnormal CODEX was significantly associated with the risk of postoperative delirium in univariate analysis and after adjustment for age (odds ratio [OR]: 13.33; 95% confidence interval, [95%CI]: 1.85±∞; P<0.003). CONCLUSION: Abnormal preoperative rapid screening test CODEX is independently associated with postoperative delirium in older people undergoing hip fracture surgery and free of known dementia.

What is the role of TPE in management of patients at risk or with pressure ulcer as of 2012? Developing French guidelines for clinical practice.

INTRODUCTION: Pressure ulcer (PU) is a common complication in chronic affection, especially neurological disorders and diseases commonly diagnosed in the elderly. For a long period of time, the prevention of skin lesions was taught only in an empirical manner. The development of therapeutic patient education (TPE) sheds a new light on care management for patients with chronic pathologies. OBJECTIVES: Determine the place of TPE in persons at risk of and/or already suffering from pressure ulcer (PU) as of 2012. METHODS: The methodology used is the one promoted by SOFMER, including: a systematic review of the literature with a query of the PASCAL Biomed, PubMed and Cochrane Library databases for data from 2000 through 2010; a compendium of prevailing professional practices and advice from a committee of experts. RESULTS: The review of the literature found six studies including four controlled trials in patients with chronic neurological impairments (most of them with spinal cord injury). No studies were found regarding the elderly. The level of evidence for efficacy in persons with spinal cord injury (SCI) is moderate. The clinical practice study focuses on programs currently underway, dedicated to SCI patients or elderly populations. DISCUSSION: The approach proposed through TPE has its role in a strategy aimed at preventing PU in persons at chronic risk of developing PU. The educational objectives and techniques used must be adapted to the clinical and psychological context and are debated in this review. The co-construction of programs, recommended in the official texts on therapeutic education in France, should help to tailor these programs to the patients' needs. CONCLUSION: TPE is relevant in care management or prevention of PU in persons at chronic risk, patients with spinal cord injury (Grade B) or elderly subjects (Grade C).
