Insights
This study found that children reliably identify pain locations after laparoscopic surgery using a specific tool. An electronic version may improve its acceptance and professional usability.
Area of Science:
- Pediatric Surgery
- Pain Management
- Reliability Studies
Background:
- Accurate pain assessment in children post-surgery is crucial for effective management.
- Existing pain location tools require validation for pediatric populations, especially after minimally invasive procedures.
Purpose of the Study:
- To evaluate the inter-rater and test-retest reliability of a pain location tool in pediatric patients.
- To explore children's preferences for tool format and identify areas for improvement.
Main Methods:
- Children aged 5-14 years, post-laparoscopic surgery, reported pain at specific abdominal and shoulder locations.
- Pain scores were recorded at baseline, 5 minutes, and 30 minutes to assess reliability.
Main Results:
- The pain location tool demonstrated moderate to substantial inter-rater and test-retest reliability.
- A significant majority (75%) of children expressed a preference for an electronic version of the tool.
- Thematic analysis indicated opportunities to enhance accuracy, usability, and overall usefulness.
Conclusions:
- The validated pain location tool enables reliable self-reporting of pain sites in children following laparoscopic surgery.
- Transitioning to an electronic format could enhance patient acceptability and clinical utility.
Aim:
To determine the 'inter-rater' and test-retest reliability of a pain location tool for children.
Materials & Methods:
In children aged 5-14 years who had undergone a laparoscopic operation, pain scores at each of seven abdominal locations, and at the shoulder tip, were recorded at baseline and after a 5- and 30-min interval.
Results:
Intraclass correlation coefficients were predominantly in the 'moderate' to 'substantial' range for both 'inter-rater' and test-retest reliability. Three quarters of children would prefer an electronic version of the tool. Thematic analysis showed accuracy, usability, utility and usefulness were areas for future development.
Conclusion:
Children can reliably indicate where they hurt after laparoscopic surgery. An electronic version could increase acceptability to children and usability by professionals.
