Development of a novel diagnostic system for a telepsychiatric application: a pilot validation study

Area of Science:

• Digital health
• Telepsychiatry
• Psychiatric diagnostics

Background:

• A telepsychiatry service developed a net-based decision support system for psychiatric disorder assessment in underserved remote Indian populations.
• The system is a bilingual (English and Hindi) tool for adult patients, featuring screening and criteria-based diagnostic modules for 18 disorders.

Purpose of the Study:

• To describe the development and preliminary diagnostic validation of a telepsychiatry decision support system.
• To assess the accuracy and feasibility of the diagnostic tool among adult outpatients.

Main Methods:

• The diagnostic tool was evaluated on 100 adult outpatients.
• Comparisons were made against semi-structured clinical assessments by a consultant psychiatrist.
• Key metrics included diagnostic accuracy, sensitivity, specificity, predictive values, completion rates, and user satisfaction.

Main Results:

• The screening module demonstrated high sensitivity and specificity.
• Diagnostic sub-modules showed moderate to substantial agreement with consultant diagnoses (kappa 0.4-0.6, >0.6), with high specificity and negative predictive values.
• The system achieved a 100% completion rate, with an average assessment time of 30 minutes, and received positive feedback from patients, relatives, and interviewers.

Conclusions:

• The diagnostic system is comprehensive, time-efficient, and feasible.
• It demonstrates an acceptable level of diagnostic accuracy, making it suitable for telepsychiatric applications.
• The tool shows potential for improving mental healthcare delivery in remote areas.
