Clinical Trial Summary
Patient non-adherence to treatment recommendations is common and decreases the effectiveness
of Chronic Heart Failure (CHF) treatment. Improving adherence towards medication intake,
physical activity, symptom monitoring/management might prolong life, alleviates symptoms,
increases quality of life, and reduces hospital admissions. The Adherence Improving
self-management Strategy (AIMS) is a nurse delivered intervention, integrated in routine
clinical care, aiming to better support patients in their treatment. AIMS has previously been
demonstrated to be (cost) effective amongst HIV patients. Based on the literature and
advisory boards with healthcare providers and CHF patients, AIMS is adapted to CHF
(AIMS-CHF).
The aim of the study is to evaluate the effectiveness of the AIMS intervention on adherence
regarding medication, physical activity, and symptom management compared to
treatment-as-usual in patients with chronic heart failure.
Description:
◦Quality assurance plan that addresses data validation and registry procedures, including any
plans for site monitoring and auditing.
Data for the primary outcome medication adherence will be monitored electronically and data
will be downloaded during regular clinic visits and automatically downloaded to a protected
study server. The quality of electronically monitored medication adherence data depends on
whether the electronic monitors are used adequately. The research team will monitor adequate
use of these electronic monitors at the start of the study.
Data for secondary outcomes will be collected through questionnaires and the research team
will follow-up on participants not completing those. Statistical analysis plans will be
uploaded before data collection is completed and the database is accessed.
◦Data checks to compare data entered into the registry against predefined rules for range or
consistency with other data fields in the registry.
The quality of electronically monitored medication adherence data depends on whether the
electronic monitors are used adequately. At study exit, data will be discussed with all
patients. When electronic monitoring data is completely missing or suggests very low
adherence (depending on the sample distributions, but this could be e.g., <50% of doses
taken) in the presence of well-controlled symptoms; and the participant self-reports poor use
of the electronic monitor, then a sensitivity analysis will be conducted with those
electronic monitoring data replaced by the participants' self-reported adherence.
Physical activity, will be self-reported. The validity of this self-report will be examined
against electronic physical activity measures used by participants in the treatment arm.
◦Source data verification to assess the accuracy, completeness, or representativeness of
registry data by comparing the data to external data sources (for example, medical records,
paper or electronic case report forms, or interactive voice response systems).
Not applicable
◦Data dictionary that contains detailed descriptions of each variable used by the registry,
including the source of the variable, coding information if used (for example, World Health
Organization Drug Dictionary, MedDRA), and normal ranges if relevant.
Not applicable
◦Standard Operating Procedures to address registry operations and analysis activities, such
as patient recruitment, data collection, data management, data analysis, reporting for
adverse events, and change management.
Patient recruitment Heart failure patients in outpatient clinic will be approached by the
health care professional to inform them about the study and subsequently an information
letter will be handed over. This letter contains information concerning the nature, purpose
and duration of the study as well as possible objections, risks of participation and the
possibility to withdrawal at any time without the need to specify the reason. Subsequently,
the treating physician, or the researcher, will explain all study procedures and answer any
questions. In case the patient is willing to participate and deemed eligible, he/she is asked
to sign the informed consent form, preferably in presence of their partner, family member or
friend.
Data will be handled confidentially and will not be distributed to third parties. After
informed consent, each participant will be given a unique code consisting of letters (the
code name of the study) and a number (e.g. 001). The key linking to the patient identity will
be stored in a secured file and only the involved investigators will have access to this key.
Personal data will be handled in accordance with the Dutch Personal Data Protection Act. The
research data will be stored for 15 years after finalisation of the project. The data
required for the trail will be collected and stored in the electronic Case Report Form (eCRF)
using Castor (Castor EDC 2019.1.15 or further, Ciwit B.V., The Netherlands) and afterwards
exported to SPSS statistics 25 or R for the analyses. Only the involved investigators will
have unrestricted access to all pseudonymized data. Patients in the intervention group will
monitor their behaviour. For medication adherence applies each time they open the MEMS bottle
or push the button the date will be registered. The MEMS cap is ISO 9001 certified,
CE-marked, HIPPA compatible, compliant with FDA 21 CFR part 11 and GDPR compliant. Stored
information can be transferred at any time through the MEMS Reader to the MEMS adherence
software for immediate analysis and interpretation. The data transmission can be done using a
dedicated MEMS USB NFC reader. The data is securely transferred and stored encrypted on
AARDEX servers using end-to-end encryption. Data storage is secured by continuous backups and
data replication. The data is only accessible when logging in with the correct credentials
(login/email and password), and only be accessible for the HCP (direct feedback) and the
researcher (data analysis).
For the activity tracker applies the following; the data from the activity tracker is in the
possession of the patient itself, and will share these data with the HCP. During wear-time,
the activity tracker continuously collects data about the stepping, time of the patient. Data
collection and storage of the activity tracker is GDPR compliant and data is stored on secure
servers protected with pseudonymization and encryption.
Study related correspondence, signed Informed Consent forms, and source documents are to be
maintained by the study site and archived in a locked cabinet for a minimum of 15 years after
the end of this study. Source data will be entered at worksheets in the eCRF and afterwards
exported to SPSS statistics 25 or R for the analyses.
- Sample size assessment to specify the number of participants or participant years
necessary to demonstrate an effect.
136 patients will be recruited (based on a Sample size calculation: effect size: 0.5223;
1-β=0.80; α=0.05, and assuming a 15% dropout).
- Plan for missing data to address situations where variables are reported as missing,
unavailable, non-reported, uninterpretable, or considered missing because of data
inconsistency or out-of-range results.
Depending on the type of missingness (e.g., at random, completely at random) appropriate data
imputation procedures will be used if no alternative data sources for the missing datapoint
is available
◦Statistical analysis plan describing the analytical principles and statistical techniques to
be employed in order to address the primary and secondary objectives, as specified in the
study protocol or plan.
Primary outcome variable Linear mixed-effects models will be used to assess the effects of
AIMS-HF versus treatment-as-usual on dosing adherence measured with MEMS. Baseline dosing
adherence will be used as covariate and intervention assignment as the treatment variable
(0/1). Mean dosing compliance will be calculated per 3-month period and included as repeated
time points.
Secondary study parameter(s) Regression analyses will be conducted for the secondary outcomes
(questionnaires), where the baseline value of the dependent variables and the treatment
variable (0/1) are included as the predictors.
Tertiary study parameter(s) To explore the effects on event-free survival (time to the first
event) Kaplan-Meier survival analysis will be conducted.
