IoT-Based Intelligent Medication Dose Calculator for Kids in Drugstore Zhe Jie Tan, Ricky Jin Yuan Kiing, Ahmad Amirul Hakimi Ahmad-Sabri, Noor Shafika Mohd-Rafee, Nur Afiqah Junizan, *Wan Amir Fuad Wajdi Othman School of Electrical & Electronic Engineering, Universiti Sains Malaysia, 14300 Nibong Tebal, Pulau Pinang, Malaysia *Corresponding E-mail: wafw_othman@usm.my Abstract— This paper introduces an IoT-based system for medication dose calculator for kids in drugstore. The system will display the correct type and dosage amount of medicine for children based on the common illness among them by measuring their body weight. This device is specific only for the used in the clinic and drugstore. It also based on the apps application. The common illness that we take into consideration is fever, flu, asthma, headache, cough and cough with phlegm. By entering weight (manual) or measure the weight on the scale (automatic), we can provide suitable medicine type based on the children weight entered or measured with the correct dosage amount based on specific formula.

INTRODUCTION Generally, fixed-dosing regimen is potentially more convenient than weight-adjusted dosing regimen for both patients and clinicians. However, for the sake of safety and efficacy, weight-based dosing method is needed for population and specified in prescribing information for many medications. Joint Commission International (JCI) Accreditation Standards for Hospitals (5th edition) requires that the hospital policy should specify the weight-based dosing strategy in the circumstance such as pediatric patients and frail elderly patients. Pharmacist should consider writing weight- adjusted orders whenever possible. Organizations must strive for strategies that achieve goals such as establishing processes for weighing and weight documentation, requiring pharmacy review of weight-based dosing regimens, ensuring sufficient and convenient availability of appropriate and properly functioning equipment for patient weighing and medication delivery, and using health information technology and clinical decision support software to promote safe and appropriate dosing. However, prescribing appropriate doses of drugs requiring weight-based dosing is still challenging due to poor awareness and adherence. A study showed that 3–12-year-old children with uncomplicated malaria were significantly more susceptible to receive wrong dose of artemether lumefantrine, which should be prescribed based on body weight. A retrospective cohort study of vancomycin prescribing in the emergency department (ED) showed that only 19.6% of patients received a consensus-guideline recommended dosing regimen (15–20 mg/kg). The effect of body weight on drug action may vary in extent. In some cases, weight can primarily determine the dosage; in other cases, the weight effect may be minimal, or dosage can be affected only when weight is combined with other factors. Findings of sporadic studies in recent years indicated that fixed dosing was more advantageous than weight-based dosing in some cases, and some key factors may challenge the
