Feasibility and Acceptability of a Wrist-Worn Digital Pill System for HIV PrEP Adherence

A 30-day pilot study from 2026 by Dhruv Nimbalkar, assessing a next-generation ingestible sensor system for measuring HIV pre-exposure prophylaxis (PrEP) adherence. The dataset includes results from 15 participants, with adherence measured via the digital pill system, pill counts, and user feedback via the System Usability Scale. It contains 49.9 KB of data in an Excel file, published under a CC-BY-4.0 license.

Use Cases

• Validate digital pill system accuracy by comparing system-detected ingestions to pill counts.
• Assess user acceptability and system usability based on System Usability Scale (SUS) scores and qualitative feedback.
• Analyze engagement patterns with a wrist-worn receiver over a 30-day study period.
• Compare user preference between lanyard-based and wrist-worn digital pill reader form factors.

Strengths

• Includes data from a 30-day prospective cohort study with 15 participants.
• Provides a direct accuracy comparison between digital pill detection and pill counts, reporting a correlation of r=0.75.
• Captures quantitative acceptability metrics with a mean System Usability Scale score of 78.0 (± 9.4).
• Contains qualitative user feedback on system usability and convenience.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 49.9 KB size indicates a very limited scope from a small pilot study.
