What does the percentage mean?
Understand how percentage values are calculated in HiBoop reports and what they tell you about patient outcomes.
Percentage values appear in several places in HiBoop's reporting views. Here's what each means.
Severity distribution percentages
In clinic-level reports, percentages show the proportion of patients currently in each severity category for a given assessment. For example:
- 42% Minimal, 42% of patients who completed the PHQ-9 scored in the Minimal severity range
- 28% Mild, 18% Moderate, 12% Moderately Severe / Severe
These percentages are calculated from all patients included in the current filtered view.
Change percentages (trend indicators)
Trend indicators show the percentage change in mean score between two time periods (e.g., current month vs. previous month). A negative percentage indicates improvement (lower score), while a positive percentage indicates worsening symptoms on average.
Example: −14% next to PHQ-9 means the average score across your patient population decreased by 14% compared to the prior period.
Patient-level improvement rate
In aggregate reports, HiBoop shows the percentage of patients who showed a clinically meaningful improvement (typically defined as a 5-point or 50% reduction in score from intake to most recent assessment).
Why percentages rather than raw numbers?
Percentages normalize across different clinic sizes and time periods, making it easier to compare trends across cohorts or over time regardless of how many patients you have in care.
