Efficacy of self-sampling in promoting participation to cervical cancer screening also in subsequent round.

ABSTRACT: Offering self-sampling devices improves participation of under-screened women. We evaluated participation in routine screening following the self-sampling intervention in two organized population-based screening programmes located in North-East Italy. Data on participation at 3-years-interval after a randomized clinical trial assessing the response to two strategies offering self-samplers (sent at home or offered free at local pharmacy) with a control action (sending reminders for a cervical specimen taken at the clinic) in 30-64 yr-old women non-respondent to the regular call-recall invitation were analyzed. Up to April 2016, 2300 women out of the 2995 recruited in the trial in 2011 were re-invited to perform a screening test at clinic; overall, 698 women adhered. Participation was similar in the three arms (29-32%), and highest (47-68%) among those who participated in the previous round. Over the two rounds, 44.6%, 32.3% and 30.3% women had at least one test in the self-sampling at home, self-sampling at pharmacy and test at the clinic arms, respectively. Our data indicate that the beneficial effect of offering self-sampling devices to nonparticipating women is maintained over time. Self-samplers are useful to increase overall coverage; their sporadic use does not seem to increase the proportion of women regularly repeating the test.

Project description:BackgroundIncidence and mortality rates of cervical cancer in Bolivia are the highest in Latin America. Vaginal cell self-sampling can improve screening coverage. Information on common reasons for low screening coverage and preferences for future screening are essential to reduce cervical cancer incidence. We aimed to evaluate the knowledge about human papillomavirus (HPV) and cervical cancer of Bolivian women from urban, peri-urban and rural areas of Cochabamba and to determine their degree of acceptability and confidence towards vaginal HPV self-sampling. In addition, we assessed the impact of self-sampling on cervical cancer screening coverage in a selected peri-urban area.MethodsWe gathered information from women living in urban, peri-urban and rural areas of Cochabamba province in Bolivia using two different structured questionnaires. In Survey1, we collected information from 222 women about their knowledge on HPV and cervical cancer. In Survey 2, the acceptance and confidence towards vaginal HPV self-sampling compared to the physician-sampling was assessed in 221 women. A non-probabilistic stratified sampling by areas was carried out for the two questionnaires. In the third phase of the study, we determined the impact of HPV self-sampling collection on screening coverage in a peri-urban area of Cochabamba.ResultsBolivian women knew little or nothing about cervical cancer and HPV infection in all areas. They all found self-sampling collection easier to perform (86.9 to 93.2%) and more comfortable (79.4 to 83.3%) compared to physician sampling. Sampling accuracy to detect cervical cancer was probably higher in their point of view when it was taken by physician (35.1 to 63.5%). However in rural areas women preferred self-sampling. Accordingly, the campaign of vaginal HPV self-sampling in this peri-urban area increased screening coverage, reaching in three months the annual rate average.ConclusionsThe knowledge about cervical cancer and HPV infection is poor in Bolivia. Despite greater acceptance of the vaginal HPV self-sampling in all areas, women kept greater confidence in the screening performed by the gynecologist although HPV self-sampling improved coverage rate.

Project description:Whereas systematic screening programs have reduced the incidence of cervical cancer in developed countries, the incidence remains high in developing countries. Among several barriers to uptake of cervical cancer screening, the roles of religious and cultural factors such as modesty have been poorly studied. Knowledge about these factors is important because of the potential to overcome them using strategies such as self-collection of cervico-vaginal samples. In this study we evaluate the influence of spirituality and modesty on the acceptance of self-sampling for cervical cancer screening.We enrolled 600 participants in Nigeria between August and October 2014 and collected information on spirituality and modesty using two scales. We used principal component analysis to extract scores for spirituality and modesty and logistic regression models to evaluate the association between spirituality, modesty and preference for self-sampling. All analyses were performed using STATA 12 (Stata Corporation, College Station, Texas, USA).Some 581 (97%) women had complete data for analysis. Most (69%) were married, 50% were Christian and 44% were from the south western part of Nigeria. Overall, 19% (110/581) of the women preferred self-sampling to being sampled by a health care provider. Adjusting for age and socioeconomic status, spirituality, religious affiliation and geographic location were significantly associated with preference for self-sampling, while modesty was not significantly associated. The multivariable OR (95% CI, p-value) for association with self-sampling were 0.88 (0.78-0.99, 0.03) for spirituality, 1.69 (1.09-2.64, 0.02) for religious affiliation and 0.96 (0.86-1.08, 0.51) for modesty.Our results show the importance of taking cultural and religious beliefs and practices into consideration in planning health interventions like cervical cancer screening. To succeed, public health interventions and the education to promote it must be related to the target population and its preferences.

Project description:ObjectiveTo compare the costs and effects of three sampling strategies for human papillomavirus (HPV) primary screening.DesignCost-consequence analysis from a health system perspective using a deterministic decision tree model.SettingEngland.ParticipantsA cohort of 10 000 women aged 25-65 years eligible for the National Health Service Cervical Screening Programme (NHSCSP).MethodsThe model was based on the NHSCSP HPV primary screening pathway and adapted for self-sampling. It used a 3-year cycle: routine screening (year 1) and recall screening (years 2/3). Parameter inputs were informed using published studies, NHSCSP reports and input from experts and manufacturers. Costs were from 2020/2021, British pound sterling (£).InterventionsThree sampling strategies were implemented: (1) routine clinician-collected cervical sample, (2) self-collected first-void (FV) urine, (3) self-collected vaginal swab. The hypothetical self-sampling strategies involved mailing women a sampling kit.Main outcome measuresPrimary outcomes: overall costs (for all screening steps to colposcopy), number of complete screens and cost per complete screen.Secondary outcomesnumber of women screened, number of women lost to follow-up, cost per colposcopy and total screening costs for a plausible range of uptake scenarios.ResultsIn the base case, the average cost per complete screen was £56.81 for clinician-collected cervical sampling, £38.57 for FV urine self-sampling and £40.37 for vaginal self-sampling. In deterministic sensitivity analysis, the variables most affecting the average cost per screen were the cost of sample collection for clinician-collected sampling and the cost of laboratory HPV testing for the self-sampling strategies. Scaled to consider routine screening in England, if uptake in non-attenders increased by 15% and 50% of current screeners converted to self-sampling, the NHSCSP would save £19.2 million (FV urine) or £16.5 million (vaginal) per year.ConclusionSelf-sampling could provide a less costly alternative to clinician-collected sampling for routine HPV primary screening and offers opportunities to expand the reach of cervical screening to under-screened women.
