Entomological monitoring data driving decision-making for appropriate and sustainable malaria vector control in Côte d'Ivoire.

BACKGROUND: Entomological surveillance provides critical information on vectors for appropriate malaria vector control and strategic decision-making. The widely documented insecticide resistance of malaria vectors in Côte d'Ivoire requires that any vector control intervention deployment be driven by entomological data to optimize its effectiveness and appropriate resource allocations. To achieve this goal, this study documents the results of monthly vector surveillance and insecticide susceptibility tests conducted in 2019 and a review of all previous entomological monitoring data used to guide vector control decision making. Furthermore, susceptibility to pirimiphos-methyl and clothianidin was assessed in addition to chlorfenapyr and pyrethroids (intensity and piperonyl butoxide (PBO) synergism) tests previously reported. Vector bionomic data were conducted monthly in four sites (Sakassou, Béoumi, Dabakala and Nassian) that were selected based on their reported high malaria incidence. Adult mosquitoes were collected using human landing catches (HLCs), pyrethrum spray catches (PSCs), and human-baited CDC light traps to assess vector density, behaviour, species composition and sporozoite infectivity. RESULTS: Pirimiphos-methyl and clothianidin susceptibility was observed in 8 and 10 sites, respectively, while previous data reported chlorfenapyr (200 µg/bottle) susceptibility in 13 of the sites, high pyrethroid resistance intensity and increased mortality with PBO pre-exposure at all 17 tested sites. Anopheles gambiae sensu lato was the predominant malaria vector collected in all four bionomic sites. Vector density was relatively higher in Sakassou throughout the year with mean biting rates of 278.2 bites per person per night (b/p/n) compared to Béoumi, Dabakala and Nassian (mean of 48.5, 81.4 and 26.6 b/p/n, respectively). The mean entomological inoculation rate (EIR) was 4.44 infective bites per person per night (ib/p/n) in Sakassou, 0.34 ib/p/n in Beoumi, 1.17 ib/p/n in Dabakala and 1.02 ib/p/n in Nassian. The highest EIRs were recorded in October in Béoumi (1.71 ib/p/n) and Nassian (3.22 ib/p/n), in July in Dabakala (4.46 ib/p/n) and in May in Sakassou (15.6 ib/p/n). CONCLUSION: Based on all results and data review, the National Malaria Control Programme developed and implemented a stratified insecticide-treated net (ITN) mass distribution in 2021 considering new generation ITNs. These results also supported the selection of clothianidin-based products and an optimal spraying time for the first indoor residual spraying (IRS) campaign in Sakassou and Nassian in 2020.

The Wisconsin Tobacco Quit Line's Fax to Quit program: participant satisfaction and effectiveness.

OBJECTIVE: The purpose of this study was to assess the Wisconsin Tobacco Quit Line's (WTQL) clinic-based Fax to Quit (FTQ) provider referral program in terms of participant satisfaction and short-term quit outcomes, and to compare those findings to a non-FTQ provider referral group. METHODS: A sample of 432 WTQL callers completed a telephone survey approximately 3 months after they received WTQL services. Of these, 265 contacted the WTQL based on a clinic referral and served as the basis for analyses. Of these 265, 158 FTQ respondents were compared to 107 non-FTQ respondents in terms of satisfaction with the WTQL as well as quit attempts and tobacco abstinence. RESULTS: Overall, survey respondents reported high levels of satisfaction with the WTQL (FTQ = 96.8%, non-FTQ = 92.7%). Other measures of satisfaction (cultural sensitivity, respondent needs and concerns understood) showed similarly high levels of respondent satisfaction for both groups. FTQ respondents reported a statistically significantly higher 30-day abstinence rate (46.8%) compared to non-FTQ respondents (32.7%). CONCLUSIONS: Participants expressed high levels of satisfaction with WTQL services and demonstrated high short-term quit rates. FTQ-referred WTQL users reported higher rates of tobacco cessation than non-FTQ-referred WTQL users. These findings suggest that fax referral has potential to successfully link smokers visiting primary care clinics to the WTQL, an evidence-based cessation option.

Is a statewide tobacco quitline an appropriate service for specific populations?

OBJECTIVE: To assess whether smoking quit rates and satisfaction with the Washington State tobacco quitline (QL) services varied by race/ethnicity, socioeconomic status, area of residence (that is, urban versus non-urban), or sex of Washington QL callers. METHODS: From October 2004 into October 2005, we conducted telephone surveys of Washington QL callers about three months after their initial call to the QL. Analyses compared 7-day quit rates and satisfaction measures by race/ethnicity, education level, area of residence and sex (using alpha = 0.05). RESULTS: We surveyed half (n = 1312) of the 2638 adult smokers we attempted to contact. The 7-day quit rate among survey participants at the 3-month follow-up was 31% (CI: 27.1% to 34.2%), 92% (CI: 89.9% to 94.1%) were somewhat/very satisfied overall with the QL programme, 97% (CI: 95.5% to 98.2%) indicated that they would probably/for sure suggest the QL to others and 95% (CI: 92.9% to 96.4%) were somewhat/very satisfied with the QL specialist. Quit rate did not vary significantly by race/ethnicity, education level, area of residence or sex. Satisfaction levels were high across subpopulations. Almost all participants (99%) agreed that they were always treated respectfully during interactions with QL staff. CONCLUSIONS: The Washington QL appeared effective and well received by callers from the specific populations studied. States choosing to promote their QL more aggressively should feel confident that a tobacco QL can be an effective and well received cessation service for smokers who call from a broad range of communities.
