Insights
Patient-controlled analgesia (PCA) for pediatric sickle cell vaso-occlusive episodes (VOE) is initiated within hours of admission. Lower PCA ratios, indicating higher continuous infusion rates, were associated with fewer adjustments needed within six hours.
Area of Science:
- Pediatric Hematology
- Pain Management
- Sickle Cell Disease
Background:
- Sickle cell vaso-occlusive episodes (VOE) are a common cause of hospitalization in children.
- Effective pain management, often utilizing patient-controlled analgesia (PCA), is crucial for managing VOE.
- Understanding PCA administration patterns can optimize pain control and reduce healthcare resource utilization.
Purpose of the Study:
- To describe the administration of patient-controlled analgesia (PCA) in pediatric patients admitted with sickle cell vaso-occlusive episodes (VOE).
- To identify factors associated with PCA adjustments in this patient population.
Main Methods:
- A single-center retrospective study analyzed inpatient hematology admissions for VOE between 2014 and 2020.
- PCA-ratio (bolus dose/continuous IV opioid dose) and time to PCA adjustment were calculated.
- Statistical models assessed associations between patient characteristics, PCA parameters, and PCA adjustments.
Main Results:
- 866 encounters (172 patients) with PCA for VOE were included; mean age was 15.4 years.
- PCA was initiated at a mean of 3.5 hours post-admission, with a mean initial PCA-ratio of 1.7.
- Lower admission pain scores, lower PCA-ratios, longer time to PCA initiation, and absence of ketamine were associated with PCA not requiring adjustment within 6 hours.
Conclusions:
- Pediatric patients with VOE receive opioids and PCA within hours of admission at this institution.
- While no specific PCA-ratio was definitively superior, lower ratios (higher continuous infusion) correlated with fewer PCA adjustments.
- Further prospective studies are warranted to confirm optimal PCA strategies for VOE pain management.
Objective:
To describe Patient-Controlled Analgesia (PCA) administration in pediatric patients admitted with sickle cell vaso-occlusive episode (VOE).
Methods:
This single-center retrospective study included all inpatient hematology admissions for VOE between 2014 and 2020. PCA-ratio was calculated as the ratio of bolus over continuous IV opioids dose, and time to PCA adjustment as time between first PCA order and a subsequent order that increased dosing or changed opioid medication.
Results:
A total of 866 encounters (172 unique patients) with PCA for VOE were included. The mean age was 15.4 years old (SD = 5.0). On average, after admission (hospital arrival), the first opioid dose was given at 1 hour, PCA started at 3.5 hours, and mean length of stay was 4.3 days (SD = 2.5). The mean initial PCA-ratio was 1.7 (SD = 0.6). There were no significant associations between age, gender, initial pain score, or admission hemoglobin and PCA-ratio (linear regression model P = 0.443). In 24.7% of encounters, the PCA was adjusted within 6 hours. After adjusting by age and gender, lower admission pain scores (OR = 1.15, P = 0.004), lower PCA-ratio (OR = 2.1, P = 0.003), longer time to PCA start (OR = 1.2, P = 0.001), and no adjuvant ketamine (OR = 2.4, P < 0.001) were associated with PCA unadjusted within 6 hours.
Conclusion:
At our institution, patients with VOE received opioids and PCA within the first hours of admission. PCAs were started at a ratio of 1.5-1.8, considered normal continuous. While no specific PCA-ratio was clearly superior for pain control, lower ratios (high continuous infusion) were associated with not requiring PCA adjustments at 6 hours. Prospective studies are needed.
