RESUMO

Background: CervixCheck, Manitoba's cervical cancer screening program, conducted a pilot study to assess whether screening participation could be improved in unscreened women by offering a mailed self-sampling kit for human papillomavirus (hpv) testing instead of a Pap test. Methods: In a prospective cohort study design, a sample of unscreened women (n = 1052) who had been sent an invitation letter from CervixCheck in the past but who did not respond were randomized to either an intervention group or a control group. The intervention group received a mailed hpv self-sampling kit; the control group received no additional communication. Returned hpv self-sampling swabs were analyzed by a provincial laboratory. After 6 months, screening participation in the two study groups was compared using a logistic regression model adjusted for age and area of residence (urban or rural). Secondary outcomes included hpv positivity, specimen inadequacy, compliance with follow-up, and time to colposcopy. Results: Screening participation was significantly higher in the intervention group than in the control group (n = 51, 9.6%, vs. n = 13, 2.5%; odds ratio: 4.7; 95% confidence interval: 2.56 to 8.77). Geographic area of residence (urban or rural) and age were not statistically significant. Conclusions: The study demonstrated that hpv self-sampling kits can enhance screening participation in unscreened non-responder women in the setting of an organized screening program. Next steps should include additional research to determine the best implementation strategy for hpv self-sampling in Manitoba.

RESUMO

OBJECTIVE: Cytotechnologist (CT) screening workload has been decreasing due to the falling number of Papanicolaou tests. This continuing trend has prompted exploration of ways to best employ the CT skillset. One potential way of more effective use is by having two CTs double screen non-gynaecological (NGC) cases to assess whether this improves screening quality and concordance with pathologists. Another is evaluating the CT's performance on low-complexity negative NGC cases for a potential independent CT sign-out without pathologist review. METHODS: In total, 1119 NGC cases were reviewed; 577 screened by two CTs and 542 screened by one CT. All cases were signed out by a pathologist and all CT interpretations were compared to the pathologist final diagnoses. The disagreements were classified based on degree of discrepancy. The extra workload by adding the second screener was assessed. RESULTS: The agreement rate between the CT's screening interpretation and pathologist's interpretation did not improve by adding a second CT compared to a single screener (91.5% vs 92.9%, respectively). CT to pathologist concordance was very high on low complexity NGC cases (voided urine, fluid, sputum) whether screened and interpreted as negative by one CT (97.3%) or two CTs (99.3%). CONCLUSION: Double screening of NGC cases by two cytotechnologists prior to pathologist sign-out does not improve screening quality and is not cost-effective. The high concordance between the CTs and pathologists in this limited group of low complexity negative cases suggests that such cases could be signed out independently by cytotechnologists.

RESUMO

This study was a double blind comparison of three types of hearing aid circuits: Class A linear peak clipping, Class D compression limiting and K-Amp wide dynamic range compression. Subjective ratings, speech perception tests, real ear measurements and questionnaire data were obtained from a group of 17 new hearing aid users with mild to moderate sensorineural hearing loss. The results indicate a similar performance for all three circuits. We saw no evidence of performance degradation due to saturation distortion, even in the presence of high levels of speech and noise. Our primary conclusions include recommending K-Amps to new hearing aid users with mild to moderate hearing loss, mostly on the basis of battery life, while cautioning about the use of compression knee-point controls and recognizing that Class A and Class D amplifiers are virtually equivalent in every performance measurement.
