The EuroQol-5D (EQ-5D) questionnaire is a standardised tool used to measure health status for clinical and economic appraisal. Gro Health users were invited to complete the EQ-5D at baseline and 6 months after using the app.
Users provided informed consent for use of their anonymised data for research purposes. Health index scores (HIS) and visual analogue scale (VAS) scores were calculated at baseline and 6 months for individuals with prediabetes and type 2 diabetes (T2DM).
Descriptive statistics and multiple-regression models were utilised to assess changes in outcome measures and determine the driving variables for change in HIS.
HIS are average values that reflect people’s preferences about their health state (1=full health, 0=moribund). There was a significant and clinically meaningful increase in mean HIS amongst app users between baseline and follow-up.
The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain.
There was a 18.3% mean improvement in VAS scores from baseline to follow-up.
These VAS score improvements remained significant across age, gender, ethnicity, income, and diagnosis (prediabetes/T2DM).
Baseline HIS, ethnicity and education variables were associated with significant changes in follow-up HIS.
