An Integrated Solution for Sustainable Care for Multimorbid Elderly Patients With Dementia

An Integrated Solution for Sustainable Care for Multimorbid Elderly Patients With Mild Cognitive Impairment or Mild Dementia (CAREPATH)

The CAREPATH will conduct Technical Validation and Usability (TVU) study by involving ≥ 45 target end users (16 patients with MCI or mild dementia with their informal caregivers and 16 healthcare professionals from various disciplines) and Clinical Investigation (CI) study involving ≥ 200 patients (≥ 100 users to pilot the CAREPATH platform and ≥ 100 patients as reference cases). Both of these pilot studies will be coordinated in four European countries (Spain, Romania, Germany and UK) with diverse health and social care systems, ICT landscape/digital maturity of healthcare provision and dementia national programs, which will allow for strengthening the evidence base on health outcomes and efficiency gains.

The CAREPATH outcomes can be summarized as:

1. An Integrated Care Platform that jointly addresses multimorbidity, dementia and diminished intrinsic capacity and optimally manages healthcare interventions for its users (patients, informal caregiver, healthcare providers, etc).
2. Technical Validation and Usability (TVU) study involving over 45 users and Clinical Investigation (CI) involving over 200 patients that will be conducted in four European countries (Spain, Romania, Germany and UK) during two years and mobilizing the other necessary actors, such as caregivers and healthcare professionals, for the validation of healthcare interventions.
3. Dementia / Multimorbidity Guidelines that will be conceived for best healthcare delivery.
4. Health Economics Impact Assessment for healthcare cost effectiveness and care provision equalities. The incremental cost-effectiveness and the incremental cost-utility ratio would allow revealing the incremental cost (or the potential savings) per unit of benefit of switching from usual care to CAREPATH-an integrated patient-centred approach- in multimorbid elderly patients with dementia, and therefore, to determinate whether the CAREPATH approach would be considered as a cost-effective alternative.

The study will have two parts:

A. Usability study In order to ensure that the CAREPATH system is well-usable by its main target user groups namely patients with Mild Cognitive Impairment (MCI) or mild dementia, their informal caregivers and health care professionals in charge of caring for this patient group, a usability evaluation of the platform will be conducted as part of the Technical Validation and Usability (TVU) study described in chapter 1.3.6 of the proposal (IEC TR 62366-2: 2016-04 Medical devices - Part 2: Guidance on the application of usability engineering to medical devices). It will be carried out at the end of the main development phase to investigate usability issues and its results will serve as input for the (re-)design of the platform before the clinical investigation starts. Implementation of good usability of a medical device such as the CAREPATH platform is also enforced by the usability engineering process required now in the development of a medical devices by the new Medical Device Regulation (Regulation (EU) 2017/745) (Regulation (EU) 2017/745 of the European parliament and of the council of 5 April 2017 on medical devices, amending Directive 2001/83/EC, Regulation (EC) No 178/2002 and Regulation (EC) No 1223/2009 and repealing Council Directives 90/385/EEC and 93/42/EEC) which originates in the concern that increasing complexity and interactivity of medical devices bears a high risk of errors in handling if poorly designed causing harm to patients. Therefore, usability and safety are seen as interrelated and in the CAREPATH usability study possible hazardous situations will also be taken into account.

B. Clinical Investigation with a Medical Device class IIa After finishing the TVU, a Clinical Investigation will be conducted in order to validate the technological system CAREPATH for multimorbid elderly patients with MCI up to mild dementia (see Work Package 5 of the complete proposal). This version of CAREPATH will include the modifications made by engineers in the system after the analysis of the TVU phase.

The main objective will be to analyze the reduction in healthcare appointments and the hypothesis is that CAREPATH will improve Quality of Life (QoL) of these patients through a multicomponent approach based on the 5 following principles:

1. Identification of purpose.
2. Establishment of disease and treatment burden, by considering how a person's health problems affect their day-to-day life, their mental health and their wellbeing.
3. Formulation of patient goals, values and priorities
4. Communicating to patients and caregivers the benefits, risks and costs of treatments and medications.
5. Provision of an individualised care plan.

Inclusion Criteria:

• Women and men aged ≥ 65 years old (randomization will warrant that at least 40% of each sex will be included in the study).

• Meets NIAAA core clinical criteria for probable Alzheimer disease, dementia or Mild Cognitive Impairment due to Alzheimer´s Disease (consistent with the NIAAA diagnostic criteria and guidelines for MCI; Albert MS, DeKosky ST, Dickson B, et al. The diagnosis of mild cognitive impairment due to Alzheimer's disease: Recommendations from the National Institute on Aging Alzheimer's Association workgroups on diagnostic guidelines for Alzheimer's disease. Alzheimer's & Dement 2011; 7: 270-9)

• Mild symptomatology, as defined by a screening MMSE score of ≥ 22 points and CDR-GS of 0.5 or 1.0.

• Evidence of retrospective decline in cognitive functions.

• Multimorbidity: Presence of at least one of the following chronic diseases: Diabetes mellitus needing pharmacologic treatment, hypertension needing pharmacologic treatment, heart failure NYHA class 2-4, atrial fibrillation with a CHA2DS2-Vasc, chronic obstructive pulmonary disease (COPD) GOLD staging B-D, asthma needing pharmacologic treatment or chronic kidney disease (CKD) stage III-V.

• Living at home.

• Independence for basic activities of daily living.

• Availability of a person (referred to as the "caregiver" throughout this protocol) who in the investigator's judgment:

  • Has frequent and sufficient contact with the patient to be able to provide accurate information regarding the patient's cognitive and functional abilities, agrees to provide information at clinic visits (which require partner input for scale completion), signs the necessary consent form, and has sufficient cognitive capacity to accurately report upon the patient's behavior and cognitive and functional abilities.
  • Is in sufficiently good general health to have a high likelihood of maintaining the same level of interaction with the patient and participation in study procedures throughout the study duration.
  • Note that every effort should be made to have same caregiver participate throughout the duration of the study.

• Fluency in the language used at the study site.

• Willingness and ability to complete all aspects of the study; the patient should be capable of completing assessments either alone or with the help of the caregiver.

• Adequate visual and auditory acuity, in the investigator's judgement, sufficient to perform the neuropsychological testing (eye glasses and hearing aids are permitted).

• Patient must have completed at least 6 years of formal education after the age of 5 years.

• Able to provide written consent signed by the patient (co-signed by the patient's legally authorized representative, if required by the local regulations, guidelines, and independent ethics committee or institutional review board [IRB]).

  • Patients should be judged by the investigator to be lucid and oriented to person, place, time, and situation when giving the informed consent.
  • In judging capacity, the investigator must confirm that the patient is able to understand the information relevant to the decision to participate in the study, appreciate the situation in terms of the treatment and research options and their likely outcomes, and weigh the potential risks and benefits of participation in order to come to a decision and communicate that decision.
