Development of a Recurrent Drug Allergy Prevention System in Hospitals by Integrating Online Allergy Histories within the Sisaket Provincial Network

Abstract

Background: Recurrent drug allergies impact patients, families, and society. In fiscal year 2022, Sisaket Hospital reported one case of repeat drug allergy Sisaket. Hospital reports annual cases of drug allergies, with some patients having allergy histories from network hospitals. Thus, online allergy history linkage between hospitals is crucial to reduce recurrence incidents.
Objective: To develop a recurrent drug allergy prevention system by integrating online allergy histories within the Sisaket Provincial Hospital Network.
Method: This action research consisted of three steps: 1. Problem analysis and planning; 2. Developing a real-time online allergy history linkage through the HIMPRO service program and conducting pharmacist training; 3. Data analysis using SPSS with paired t-test.
The study was conducted from October 1st., 2022, to September 30th., 2024. The participants included 29 pharmacists who attended the training and 18 patients enrolled in the pilot system.
Results: After system development, cross-hospital drug allergy incidents decreased from 5 to 0 cases. Overall drug allergies reduced from 8 to 7 cases (due to patient and healthcare personnel factors). Allergy history documentation steps reduced from 3 to 1. A limitation was the lack of automatic medication allergy blocking. Pharmacists showed high system satisfaction (mean 4.2, SD 0.8). demonstrated significantly increased knowledge scores (mean = 25.3, SD 1.3) compared to pre-intervention (mean = 22.9, SD 2.0), with statistical significance (p<0.05) (95%CI: 1.6, 3.8).
Conclusions: The online drug allergy history linking system within the hospital network effectively reduced cross-hospital recurrent drug allergy incidents and streamlined the allergy documentation process, with high user satisfaction among pharmacists.
