Caregiver Burden of Wet Age-related Macular Degeneration (wAMD) in Japan

August 21, 2017 updated by: Bayer

Caregiver Burden of Wet Age-related Macular Degeneration (wAMD) Treatment in Real-life Japanese Settings.

This study aims at investigation of the caregiver burden of Wet Age-related Macular Degeneration (wAMD) patients and at the assessment of how much of caregiver burden could be reduced in transitioning from Pro Re Nata to proactive therapy especially in real-life rural settings where public transportations are not readily available.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Information on patients will be collected from all female and male out-patients with a diagnosis of wAMD who currently receive anti-VEGF therapy with proactive regimen at Kozawa Eye Hospital (Mito-city, Japan). Of these, patients who are accompanied by his/her caregiver and the caregiver (a pair of patient-caregiver) who satisfy eligibility listed below will be recruited for the assessment of primary and secondary objectives.

Description

Inclusion Criteria:

  • [Patients]

    • Female and male out-patients diagnosed with wAMD.
    • Patients who are accompanied by his/her caregiver(s).
    • Patients who have been receiving anti-VEGF therapy with proactive regimen for 12 months or more at the participating site.
    • Providing informed consent for the participation in this study.

  • [Caregivers]

    • Providing informed consent for the participation in this study.
    • Capable of understanding and completing the questionnaires without any help from others

Exclusion Criteria:

  • [Patients]

    • Presence of a disease or a condition more disabling than wAMD in term of caregiving.
    • Presence of intractable neurologic disease, physical handicap, mental handicap, or any condition that rendered them unable to walk independently.
    • Intraocular surgery for other eye diseases after the start of wAMD therapy.

  • [Caregivers]

    • Professional carers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Degree of caregiving burden on caregivers (BIC-11)
Time Frame: At enrollment
Burden Index of Caregivers (BIC), a multidimensional short care burden scale from Japan.The score range is from 0-40, with high scores indicating greater care giver burden.
At enrollment
Relationship between BIC-11 and the number of hospital visits for wAMD treatments
Time Frame: Up to 1 year
Up to 1 year
Frequency of hospital visits
Time Frame: Up to 1 year
Up to 1 year
Time spent by accompanying caregivers for a clinic visit for wAMD management (minutes)
Time Frame: Up to 1 year
Up to 1 year
Estimated costs spent by accompanying caregivers on hospital visits for wAMD management
Time Frame: Up to 1 year
Up to 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Level of depression among caregivers (CES-D)
Time Frame: At Enrollment
CES-D will be applied to determine depression.The score range is from 0 to 60, with high score indicating greater depressive symptoms. Cut off score is 16 or greater in Japan to assess whether individuals experience depression.
At Enrollment
Types of treatments for wAMD
Time Frame: At Baseline
Anti-VEGF(anti vascular endothelial growth factor)drugs, laser therapy, Photodynamic Therapy,etc.
At Baseline
Frequency of treatments
Time Frame: At baseline
Number of a therapeutic agent given to patients
At baseline
Length of treatment
Time Frame: At baseline
Duration of a therapeutic agent received
At baseline
Dosing schedule
Time Frame: At baseline
The schedule of doses of a therapeutic agent per unit of time
At baseline
Percentage of patients accompanied by primary caregivers
Time Frame: At baseline
