AbstractWomen overdue for cervical cancer screening often have other preventive care gaps. We examined whether mailing unsolicited human papillomavirus (HPV) self-sampling kits to increase cervical cancer screening impacted receipt of other preventive services women were due for: mammography, colorectal cancer (CRC) screening, influenza vaccination, depression screening, and diabetic HbA1c monitoring. From 2014 to 2016, 16,590 underscreened women were randomized to receive a mailed kit or usual care Pap reminders within Kaiser Permanente Washington. We used logistic regression to estimate odds ratios (ORs) of preventive services receipt within 12-months between the intervention vs. control arms, and within the intervention arm (comparing those returning a kit vs. attending Pap vs. nothing), adjusting models for demographic variables. There were no significant between-arm differences in uptake of any of the preventive services: intervention vs. control: mammography OR = 1.01 (95% confidence interval:0.88-1.17), CRC screening OR = 0.98 (0.86-1.13), influenza vaccination OR = 0.99 (0.92-1.06), depression screening OR = 1.07 (0.99-1.16), HbA1c OR = 0.84 (0.62-1.13). Within the intervention arm, preventive services uptake was higher in women who completed cervical cancer screening vs. did not, with stronger effects for women who attended Pap: Pap vs. nothing: mammography OR = 11.81 (8.11-17.19), CRC screening OR = 7.31 (5.57-9.58), influenza vaccination OR = 2.06 (1.82-2.32), depression screening OR = 1.79 (1.57-2.05), HbA1c OR = 3.35 (1.49-7.52); kit vs. nothing: mammography OR = 2.26 (1.56-3.26), CRC screening OR = 5.05 (3.57-7.14), influenza vaccination OR = 1.67 (1.41-1.98), depression screening OR = 1.09 (0.89-1.33), HbA1c OR = 1.23 (0.57-2.65). Mailing HPV self-sampling kits to underscreened women did not negatively impact uptake of other preventive services. However, overall preventive service uptake was the highest among women who attended in-clinic cervical cancer screening.Copyright © 2021 Elsevier Inc. All rights reserved.
