Text message and online survey protocol captured complete Giardiasis case data for one third of Colorado patients

A Colorado public health investigation evaluated a protocol combining text message invitations with an online survey for Giardiasis case investigation. The population included Colorado patients with laboratory-confirmed Giardia reported between September 2023 and May 2024. The primary aim was to facilitate rapid capture of complete case data.

The main finding was that the protocol achieved rapid capture of complete case data for one third of patients. No specific effect sizes, absolute numbers, statistical measures, or comparative data against other investigation methods were reported. Safety and tolerability of the protocol were not addressed in the report.

Key limitations include the absence of a comparator group, statistical analysis, and detailed methodology. The investigation was conducted only in Colorado, and generalizability to other settings is unknown. The report does not specify sample size, follow-up duration, or funding sources.

For practice, this describes one state's operational approach to case investigation during a specific period. The report suggests text-based methods may have utility for some public health investigations but provides no evidence of superiority over traditional methods. Clinicians should interpret this as a descriptive account rather than evidence for protocol effectiveness.
