# P-1684. Perspectives from Sri Lankan physicians on current and future tools for diagnosing and managing lower respiratory tract infections

## TL;DR

Sri Lankan physicians rely on clinical judgment for managing lower respiratory tract infections, with mixed use of guidelines and interest in electronic decision support tools.

## Contribution

The study provides insights into physician perspectives on current diagnostic practices and potential for electronic clinical decision support tools in Sri Lanka.

## Key findings

- Physicians primarily use clinical judgment and access guidelines online for managing LRTIs.
- Rapid diagnostic tests are seen as valuable but limited by cost.
- eCDSTs are perceived to improve decision-making but face challenges like internet access and local relevance.

## Abstract

Lower respiratory tract infections (LRTIs) impose a significant burden on healthcare systems, including in Sri Lanka. This study explored the attitudes, perceptions, and experiences of Sri Lankan physicians regarding their current approach to diagnosing and managing LRTIs (including the use of guidelines, rapid diagnostic tests [RDTs], and clinical decision support tools [CDSTs]). We also assessed physicians’ perspectives on the value and drawbacks of using electronic CDSTs (eCDSTs), with the goal of developing an eCDST in future to improve LRTI management.

Semi-structured interviews were conducted with 15 physicians working in six public hospitals in the Western and Southern provinces of Sri Lanka. The interview guide topics included current decision-making processes in managing LRTIs, use of guidelines and pathogen-based & biomarker-based RDTs , experience with CDSTs, and the value and drawbacks of using eCDSTs in clinical practice.

Physicians reported relying mainly on clinical judgment when managing LRTIs and generally did not consult guidelines for typical cases. When used, guidelines served as a “framework” for decision-making and were often accessed online. Physicians felt that RDTs hold value, if cost is not a barrier. Twelve physicians reported using CDSTs, such as CURB-65, TIMI score, and Wells’ score, with most accessing them via MDCalc on mobile phones. Perceived benefits of eCDSTs included improved evidence-based decision-making, enhanced efficiency, and uniformity to standardize care and reduce bias. Potential drawbacks included the tools’ inability to account for patients' unique characteristics, local reliability concerns, inconsistent internet access, and unavailability of required inputs.

Physicians relied on clinical judgment for LRTI management, using guidelines as a framework. RDTs were valued but limited by cost. CDSTs were commonly accessed and eCDSTs were seen as beneficial for evidence-based decision-making, efficiency, and standardization but raised concerns including applicability across differing patient characteristics, local relevance, internet access issues, and missing inputs. Effective eCDSTs for LRTI would need to address these limitations.
