Insights
Codeine prescriptions are common for children under 12 in Korea, particularly for outpatients. Limiting pediatric codeine use is crucial to prevent adverse events.
Area of Science:
- Pediatric pharmacology
- Public health
- Drug utilization studies
Background:
- Codeine is a commonly prescribed opioid analgesic.
- Pediatric codeine use requires careful consideration due to potential risks.
- Understanding prescription patterns is essential for safe medication practices.
Purpose of the Study:
- To determine the frequency of codeine prescriptions for children under 12 years old in Korea.
- To identify patient and healthcare system characteristics associated with pediatric codeine use.
Main Methods:
- Retrospective observational study using the Korea Health Insurance Review and Assessment Service National Patient Sample database (2011-2016).
- Analysis of pediatric codeine users (<12 years) by demographics, medical setting, and diagnoses.
- Logistic regression to identify factors associated with codeine prescription.
Main Results:
- Codeine was prescribed to 55.8% of pediatric outpatients and 1.7% of inpatients.
- Higher odds of codeine prescription were observed in outpatient clinics and public hospitals.
- Inpatient prescriptions at public hospitals showed the highest adjusted odds ratio for codeine use.
Conclusions:
- Codeine is frequently prescribed to pediatric outpatients in Korea, especially in primary care settings.
- There is a need to implement strategies to reduce unnecessary codeine prescriptions in children.
- Limiting pediatric codeine use is necessary to mitigate the risk of codeine-related adverse events.
Objectives:
To examine the extent of codeine prescriptions for children younger than 12 years in Korea and to investigate characteristics associated with pediatric codeine use.
Study Design:
A retrospective observational study was conducted to examine codeine prescriptions and patients' characteristics.
Methods:
We used the Korea Health Insurance Review and Assessment Service National Patient Sample database. The study participants were patients younger than 12 years who were prescribed codeine as inpatients or outpatients between 2011 and 2016. Pediatric codeine use was defined as codeine prescribed at least once for a child younger than 12 years. The frequency and proportion of pediatric codeine users were analyzed by age group (0-2, 3-6, or 7-11 years), sex, year, region, diagnosis, type of medical institution, and coprescribed medication. Logistic regression analyses were performed to identify characteristics associated with pediatric codeine use.
Results:
Of all patients younger than 12 years, 518,895 (55.8%) and 16,337 (1.7%) were treated with codeine in outpatient and inpatient settings, respectively. Odds of pediatric codeine prescriptions were highest for outpatients at clinics (adjusted odds ratio [OR], 1.19; 95% CI, 1.16-1.21) and public hospitals (adjusted OR, 1.56; 95% CI, 1.28-1.91) and for inpatients at public hospitals (adjusted OR, 8.38; 95% CI, 6.64-10.58).
Conclusions:
Codeine was frequently prescribed for pediatric outpatients in Korea, especially in primary care clinics. Efforts to limit codeine use in children are required to prevent the occurrence of codeine-related adverse events.
