CI-HI: The Cognitive Impairment Health Index

  • Type of Clinical Outcome Assessment (COA): Patient-reported outcome measure (PRO) and Caregiver or observer-reported outcome (CR/ObsRO)
  • Administration Mode: Self-administered
  • Therapeutic Area: Alzheimer’s disease, mild cognitive impairment (MCI), & dementia

    • CI-HI Symptom Subscales: Memory; Fatigue; Cognition; Sleep & Daytime Sleepiness; Social Satisfaction; Communication; Emotional Health; Activity Participation; Pain
  • CICR-HI Number of Independently Validated Symptom Subscales: 8
    • CICR-HI Symptom Subscales: Memory; Cognition; Social Satisfaction; Fatigue; Sleep & Daytime Sleepiness; Emotional Health; Activity Participation; Communication

Instrument Attributes

  • The CI-HI is a patient-reported outcome (PRO) measure designed to assess symptoms and health-related quality-of-life from the perspective of patients with Alzheimer’s disease, mild cognitive impairment, or dementia.
  • Designed and validated to fully satisfy regulatory and published FDA guidance for use in drug-labeling claims and measuring changes in how a patient feels and functions.
  • The CI-HI is highly relevant to patients, has low patient burden, correlates with markers of disease severity, and demonstrates low floor and no ceiling effects.
  • The CI-HI is a fully valid, reliable, responsive, and disease-specific instrument capable of measuring changes in patient-reported health in patients with Alzheimer’s disease, mild cognitive impairment, or dementia in response to therapeutic intervention during clinical trials or clinical monitoring.
  • The CI-HI was developed using extensive patient and caregiver input, including an analysis of 1,166 patient quotes and a large cross-sectional study involving 104 patients.
  • The CICR-HI measures issues that are highly relevant to patients from the perspective of the caregiver, has low participant burden, correlates with markers of disease severity, and demonstrates no floor or ceiling effects.
  • The CICR-HI is a caregiver-reported outcome (CRO/ObsRO) measures designed to assess symptoms and health-related quality-of-life of a patient with Alzheimer’s disease, mild cognitive impairment (MCI), or dementia.
  • The CICR-HI was developed using extensive caregiver input, including an analysis of 1,097 caregiver quotes and a large cross-sectional study involving 329 caregivers. The CICR-HI measures issues and symptoms that are highly relevant to patients and is easy to complete.

Instrument Scoring

All subscales are scored on a scale of 0 to 100 with 0 representing no disease burden and 100 representing the maximum level of disease burden. Symptom questions within each subscale are weighted based on participant-reported prevalence and average impact as identified through the cross-sectional study. Subscale scores are also weighted to generate a total CI-HI or CICR-HI score (0-100) representing overall disease burden.
