The impact of a culturally tailored patient navigator program on cervical cancer prevention in Latina women.

BACKGROUND Cervical cancer disproportionately affects Latina women in the United States. This study evaluated the impact of patient navigation on cervical cancer prevention in Latinas. METHODS Between January 2004 and April 2011, 533 Latina women with an abnormal Pap smear requiring colposcopy received patient navigation from their healthcare center in Chelsea, Massachusetts, to the Massachusetts General Hospital (MGH). The comparison group comprised 253 non-navigated Latinas from other primary care practices at MGH referred to the same MGH colposcopy clinic. Primary outcomes were the percentage of missed colposcopy appointments, time to colposcopy, and changes in the severity of cervical pathology at colposcopy over two time periods, 2004-2007 and 2008-2011. RESULTS The mean age in both groups was 35 years (range 22-86). Navigated women had fewer missed colposcopy appointments over time, with the average falling from 19.8% to 15.7% (p=0.024), compared with an insignificant increase in the no-show rates from 18.6% to 20.6% (p=0.454) in the comparison group. The difference in the no-show rate trend over time between the groups was significant (p<0.001). The time to colposcopy did not change in either group, though trends over time demonstrated a shorter follow-up for navigated women (p=0.010). The grade of cervical abnormality among navigated women decreased from a numerical score of 2.03 to 1.83 (p=0.035) over the two time intervals, while the severity of pathological score in the non-navigated group did not change significantly from 1.83 to 1.92 (p=0.573) in the same interval. Comparison of trends in pathological score over time showed a decrease in the severity of cervical abnormality for navigated participants compared to the non-navigated group (p<0.001). CONCLUSION Patient navigation can prevent cervical cancer in Latina women by increasing colposcopy clinic attendance, shortening time to colposcopy, and decreasing severity of cervical abnormalities over time.
