A Parallel-Group, Randomized Trial Examining Impact of Colposcopy Results Delivery by a Nurse Liaison on Patient-Reported Outcomes and Adherence.

OBJECTIVES

Cervical cancer is on the rise in Canada. Addressing patient anxiety and improving patient understanding of colposcopy and results may improve adherence. This randomized controlled trial examined the impact of colposcopy results delivery by a Nurse Liaison versus the referring primary care provider (PCP) on patient anxiety, and secondary outcomes including patient satisfaction, knowledge of diagnosis, and 9-month adherence to follow-up.

METHODS

Patients ≥18 years old presenting for initial appointment at the study colposcopy clinic were randomized 1:1 to an intervention group (Nurse Liaison) versus a control group (PCP). After receiving colposcopy results, participants completed online measures of anxiety (State-Trait Anxiety Inventory), health care satisfaction scales (Patient Satisfaction Questionnaire-18, Health Anxiety Inventory, Visit-Specific Satisfaction Questionnaire-9), self-reported colposcopy diagnosis, and demographics. Chart review at 9 months assessed adherence to recommended colposcopy follow-up. Groups were compared on continuous and categorical variables, controlling for diagnosis severity and trait anxiety.

RESULTS

The intervention group had significantly lower state anxiety with State-Trait Anxiety Inventory-state mean scores of 37.3 versus 40.7 in controls (P = 0.03). Intervention group participants were more likely to correctly report their diagnosis (84% vs. 66.3%, P = 0.003). Questionnaire responders were more likely to be in the intervention group and had a higher proportion of cervical intraepithelial neoplasia 2+ pathology. There were no differences in demographics, patient satisfaction, or adherence to follow-up between groups.

CONCLUSIONS

Direct delivery of colposcopy results by a trained Nurse Liaison was associated with decreased patient anxiety around colposcopy results, and increased patient knowledge regarding diagnosis. This model may be considered to improve patient-centred care.
