Keywords:Influenza, respiratory system, ICD-10, casemix, healthcare cost.
Introduction: Influenza is an upper respiratory infection is caused by the influenza virus. It occurs throughout the whole year in Malaysia with occasional outbreaks. Influenza-like illnesses (ILI) are generally treated as outpatient care while the more severe â€˜SARIâ€™ is managed in patient care. The Casemix system, used in healthcare professionals' practices, may help in estimating the cost of influenza management.
Methods: This cross-sectional study extracts the cost of influenza management from different public hospitals in years 2016, 2017 and 2018. Data used selected ICD-10 codes, and the cost was abstracted from Malaysian Diagnostic Related Groups (MyDRG) software. The secondary data are from 2 sources, an urban teaching hospital Hospital Cancellor Tuanku Muhriz (HCTM) and Ministry of Health (MoH) inpatient hospitals database. The sample size of the study was 586, while a structured datasheet collating patientsâ€™ sociodemographic data and cost of admission, per case, was obtained from the MyDRG software. Microsoft Excel and SPSS software were used in the analysis.
Results: Most influenza cases (61.8%) are between the ages of 0 and 10, Malays, and have similar gender proportions. Overall, the influenza treatment cost for inpatient care, totalled to RM 294,017,112. In 2018, the GDP for health consumed 3.76% of Malaysia's GDP income of RM 1.4 trillion, with an estimated RM 60,339 million used for health. Thus, the three-year public cost consumed 0.5% of 2018 GDP.
Conclusion: Influenza screening at the primary healthcare setting, health education and treatment compliance should be scale-up to minimize the cost of influenza management of the public providers.
