Evidence for direct learning curve for technique on change of cervical sampling device

Area of Science:

• Gynecologic Oncology
• Public Health Surveillance
• Medical Device Implementation

Background:

• The NHS Cervical Screening Programme recommends the Aylesbury spatula as the primary sampling device.
• A local initiative aimed to reduce cervical screening brush usage by 50% from 41.8% to manage costs and optimize resources.
• The initial inadequate smear rate was recorded at 9.93% prior to the intervention.

Purpose of the Study:

• To evaluate the impact of reducing cervical screening brush usage on the rate of inadequate smears.
• To assess the relationship between changes in sampling device utilization and cervical smear adequacy.
• To understand the implications of implementing new sampling protocols within a national screening program.

Main Methods:

• Controlled the provision of cervical smear taking equipment, specifically limiting brush availability.
• Monitored monthly inadequate smear rates and brush usage percentages before and after the intervention.
• Analyzed the correlation between reduced brush usage and changes in smear adequacy.

Main Results:

• Brush usage decreased from 41.8% to 35.2% of all procedures.
• The inadequate smear rate initially increased from 9.93% to a peak of 17.8% before returning to baseline levels.
• A temporary rise in inadequate smears coincided with the reduction in brush use, suggesting a learning curve.

Conclusions:

• The observed increase in inadequate smear rates is likely attributable to a learning curve associated with transitioning to different sampling devices.
• Healthcare providers may expect a temporary rise in inadequate smears when changing cervical sampling devices.
• Effective management of sampling device provision is crucial during protocol changes in cervical screening programs.
