Strategies to improve male involvement in PMTCT Option B+ in four African countries: a qualitative rapid appraisal

BACKGROUND: The World Health Organization recommends that antiretroviral therapy be started as soon as possible, irrespective of stage of HIV infection. This ‘test and treat’ approach highlights the need to ensure that men are involved in prevention of mother-to-child HIV transmission (PMTCT). This article presents findings from a rapid appraisal of strategies to increase male partner involvement in PMTCT services in Uganda, Democratic Republic of Congo, Malawi, and Coˆ te d’Ivoire in the context of scale-up of Option B protocol. DESIGN: Data were collected through qualitative rapid appraisal using focus groups and individual interviews during field visits to the four countries. Interviews were conducted in the capital city with Ministry of Health staff and implementing partners (IPs) and at district level with district management teams, facility-based health workers and community health cadres in each country. RESULTS: Common strategies were adopted across the countries to effect social change and engender greater participation of men in maternal, child and women’s health, and PMTCT services. Community-based strategies included engagement of community leaders through dialogue and social mobilization, involving community health workers and the creation and strengthening of male peer cadres. Facility-based strategies included provision of incentives such as shorter waiting time, facilitating access for men by altering clinic hours, and creation of family support groups. CONCLUSIONS: The approaches implemented at both community and facility levels were tailored to the local context, taking into account cultural norms and geographic regional variations. Although intentions behind such strategies aim to have positive impacts on families, unintended negative consequences do occur, and these need to be addressed and strategies adapted. A consistent definition of ‘male involvement’ in PMTCT services and a framework of indicators would be helpful to capture the impact of strategies on cultural and behavioral shifts. National policies around male involvement would be beneficial to streamline approaches across IPs and ensure wide-scale implementation, to achieve significant improvements in family health outcomes.IS

The Uptake of Integrated Perinatal Prevention of Mother-to-Child HIV Transmission Programs in Low- and Middle-Income Countries: A Systematic Review

BACKGROUND: The objective of this review was to assess the uptake of WHO recommended integrated perinatal prevention of mother-to-child transmission (PMTCT) of HIV interventions in low- and middle-income countries. METHODS AND FINDINGS: We searched 21 databases for observational studies presenting uptake of integrated PMTCT programs in low- and middle-income countries. Forty-one studies on programs implemented between 1997 and 2006, met inclusion criteria. The proportion of women attending antenatal care who were counseled and who were tested was high; 96% (range 30-100%) and 81% (range 26-100%), respectively. However, the overall median proportion of HIV positive women provided with antiretroviral prophylaxis in antenatal care and attending labor ward was 55% (range 22-99%) and 60% (range 19-100%), respectively. The proportion of women with unknown HIV status, tested for HIV at labor ward was 70%. Overall, 79% (range 44-100%) of infants were tested for HIV and 11% (range 3-18%) of them were HIV positive. We designed two PMTCT cascades using studies with outcomes for all perinatal PMTCT interventions which showed that an estimated 22% of all HIV positive women attending antenatal care and 11% of all HIV positive women delivering at labor ward were not notified about their HIV status and did not participate in PMTCT program. Only 17% of HIV positive antenatal care attendees and their infants are known to have taken antiretroviral prophylaxis. CONCLUSION: The existing evidence provides information only about the initial PMTCT programs which were based on the old WHO PMTCT guidelines. The uptake of counseling and HIV testing among pregnant women attending antenatal care was high, but their retention in PMTCT programs was low. The majority of women in the included studies did not receive ARV prophylaxis in antenatal care; nor did they attend labor ward. More studies evaluating the uptake in current PMTCT programs are urgently needed

Integrating Prevention of Mother-to-Child HIV Transmission Programs to Improve Uptake: A Systematic Review

BACKGROUND: We performed a systematic review to assess the effect of integrated perinatal prevention of mother-to-child transmission of HIV interventions compared to non- or partially integrated services on the uptake in low- and middle-income countries. METHODS: We searched for experimental, quasi-experimental and controlled observational studies in any language from 21 databases and grey literature sources. RESULTS: Out of 28 654 citations retrieved, five studies met our inclusion criteria. A cluster randomized controlled trial reported higher probability of nevirapine uptake at the labor wards implementing HIV testing and structured nevirapine adherence assessment (RRR 1.37, bootstrapped 95% CI, 1.04-1.77). A stepped wedge design study showed marked improvement in antiretroviral therapy (ART) enrolment (44.4% versus 25.3%, p<0.001) and initiation (32.9% versus 14.4%, p<0.001) in integrated care, but the median gestational age of ART initiation (27.1 versus 27.7 weeks, p = 0.4), ART duration (10.8 versus 10.0 weeks, p = 0.3) or 90 days ART retention (87.8% versus 91.3%, p = 0.3) did not differ significantly. A cohort study reported no significant difference either in the ART coverage (55% versus 48% versus 47%, p = 0.29) or eight weeks of ART duration before the delivery (50% versus 42% versus 52%; p = 0.96) between integrated, proximal and distal partially integrated care. Two before and after studies assessed the impact of integration on HIV testing uptake in antenatal care. The first study reported that significantly more women received information on PMTCT (92% versus 77%, p<0.001), were tested (76% versus 62%, p<0.001) and learned their HIV status (66% versus 55%, p<0.001) after integration. The second study also reported significant increase in HIV testing uptake after integration (98.8% versus 52.6%, p<0.001). CONCLUSION: Limited, non-generalizable evidence supports the effectiveness of integrated PMTCT programs. More research measuring coverage and other relevant outcomes is urgently needed to inform the design of services delivering PMTCT programs

Clinical use and efficacy of porcine surfactant for the treatment of RDS in infants with birth weight ≤1000 g: Experience of three years

Objective: Evaluate the clinical response to the first and subsequent doses of natural surfactant for the treatment of respiratory distress syndrome (RDS) in extremely low birth weight infants (ELBWI). Methods: Retrospective chart review of all ELBWI admitted to Neonatal Intensive Care Unit of Padova from July 1995 to December 1998 who received porcine surfactant for the treatment of RDS. Data collection included: (a) standard clinical variables (birth weight, gestational age, material steroid treatment, etc) (b) surfactant dosing), and (c) response to surfactant treatment as assessed by changes in the fraction of inspiratory oxygen (F102) and by the Oxygenation Index (OI). Outcome data (d) which included: death, duration of mechanical ventilation, duration of oxygen therapy, days in hospital stay, OI at 3,7 and 21 days of age, oxygen dependency at 28 days and at 36 week post conception were also collected. Data were analyzed by group comparison tests when comparing the groups that received one (S1), two (S2) or Three (S3) surfactant doses and by multiple regression for the "predictors" of the response to surfactant treatment and for the "predictors" of outcome. Results: Ninety-four ELBWI were evaluated. F1O2 at 12 hours after surfactant was reduced by more than one/third in 62% of the infants after the first dose, in 54% of the second doses and 61% of the third doses (non significant). S1, S2 and S3 groups had similar demographics and birth characteristics but the OI differed at 3 and 7 days (1.73±1.39, 3.34±2.15 and 6.45±5.23 at day 3 and 1.42±1.27, 1.98±1.83 and 4.03±3.91 at day 6 for S1, S2 and S3 respectively, p=0.003). The response of exogenous was not found to be a significant predictor in our multiple regression model for major outcome variables such as oxygen dependency at 28 d or 36 wk. Conclusions: In ELBWI in spite of the high percentages of good clinical response to the first, to the second and even to the third surfactant dose, response to surfactant treatment did not predict major general and respiratory outcomes

Interventions for recruiting smokers into cessation programmes

Background: Tobacco control is a top public health priority around the globe due to the high prevalence of cigarette smoking and its associated morbidity and mortality. Much effort has been focused on establishing the effectiveness of different smoking cessation strategies. This review, however, aims to address the initial challenge faced by smoking cessation programmes: recruitment of smokers. Objective: The primary objective of this review was to determine the effectiveness of different strategies for recruiting smokers into cessation programmes. The secondary objective was to determine the impact that these strategies had on smoking cessation rates at least six months after enrolment into a cessation programme Search methods: We searched the specialised register of the Cochrane Tobacco Addiction Group using a search strategy which included the terms ’recruit$’, ’invit$’, ’enter’, ’entry’, ’enrolment’) combined with (’smok$’, ’cigarette’, ’smoking cessation’, ’tobacco’) in the title, abstract or keyword fields. We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), and registers of current and ongoing trials. We also searched the reference lists of included studies. Selection criteria We included randomised controlled trials and cluster randomised controlled trials that compared at least two different methods of recruiting current smokers into a smoking cessation programme. We also included those studies which focused on the effectiveness of a smoking cessation programme as long as the study involved multiple recruitment methods and reported results of the recruitment phase. Data collection and analysis: From each included study, we extracted data on the type of participants, type of recruitment strategies (i.e., setting, mode of communication used, intensity and duration) and comparisons, and on randomisation, allocation concealment, and blinding procedures. Our primary outcome was the proportion of smokers successfully recruited to each cessation programme compared to alternative modalities of recruitment. Our secondary outcome was smoking cessation for at least six months. Given the substantial heterogeneity across recruitment interventions and participants, we adopted a narrative synthesis approach for summarising results. Main results: This review includes 19 studies with a total of 14,890 participants. We categorised the included studies according to the modes used to deliver the recruitment strategy: head to head comparison of individual recruitment strategies; comparison of the same delivery mode but with different content or intensity; and the addition of another mode to an existing recruitment method. We identified three studies that made head-to-head comparisons of different types of recruitment strategies. Of these, only one study detected a significant effect, finding that a personal phone call was more effective than a generic invitation letter (RR 40.73, 95% CI 2.53 to 654.74). Five studies compared interventions using the same delivery modes but different content. Results showed that tailored messages through an interactive voice response system resulted in a higher recruitment rate than assessment of smoking status alone using the same system (RR 8.64, 95% CI 4.41 to 16.93), and that text messages indicating scarcity of places available were more effective than generic text message reminders (RR 1.45, 95% CI 1.07 to 1.96). One study compared interventions using the same delivery mode but different intensity and found that allowing for more phone call attempts to reach potential participants can result in better recruitment (RR 1.87, 95% CI 1.61 to 2.18). Finally, 10 studies investigated the effect of adding a recruitment mode to existing recruitment strategies. Findings showed that: adding a text message reminder or real quotes from participants to a personal phone call improved recruitment of participants (RR 3.38, 95% CI 1.26 to 9.08 and RR 29.07, 95% CI 1.74 to 485.70, respectively); that adding a personal phone call to an existing newsletter can also increase recruitment rates (RR 65.12, 95% CI 4.06 to 1045.4]); that a reactive-proactive recruitment phase is more effective than a proactive phase alone (63.8% versus 47.5%, RR not available); and that active recruitment at schools is more effective than passive recruitment (p < 0.001, denominator not available for calculation of RR). Additionally, a number of studies in this category showed that providing incentives can effectively increase the number of participants recruited into smoking cessation programmes. Out of the 19 included studies, only four reported on the effect of recruitment strategy on smoking cessation at six months or longer. Three of these studies compared strategies that used the same delivery mode with different content. Their results were non-significant. The remaining three studies evaluated adding an additional mode to an existing recruitment intervention. Only one of them showed a significant difference in the levels of smoking cessation that favoured the enhanced recruitment strategy, but this may have reflected the offer of incentives once in the programme rather than the recruitment strategy itself (RR at 15 or 18 months 2.60, 95% CI 1.48 to 4.56). Authors’ conclusions: The substantial heterogeneity across the included studies restricts our ability to draw firm conclusions about the effectiveness of different recruitment strategies in relation to recruitment of participants into smoking cessation programmes or levels of smoking cessation. The limited evidence, however, suggests that the following elements may improve the recruitment of smokers into cessation programmes: personal, tailored interventions; recruitment methods that are proactive in nature; and more intensive recruitment strategies (i.e., those strategies that require increased contact with potential participants). PLAIN LANGUAGE SUMMARY: Can recruitment strategies make smokers more likely to enter programmes to help them quit smoking? A lot of time and money has been invested in programmes to help those who smoke to quit. However, there is currently not enough information about the best way to encourage smokers to enter these programmes. This review aims to identify whether certain recruitment strategies can help to increase the number of smokers enrolling into quit services. It also aims to determine whether these recruitment strategies have any impact on people successfully quitting smoking at six months or longer. This review covers 19 studies, with almost 15,000 participants, but the significant differences across these studies meant that we were unable to draw conclusive answers to our research questions. Our findings do, however, suggest that the following elements could result more people joining Interventions for recruiting smokers into cessation programmes programmes: (1) recruitment strategies tailored to the individual; (2) proactive strategies; and (3) increased contact time with potential participants. This review also highlights the areas within this field that need more attention: identifying the elements of a recruitment strategy that are more likely to effectively engage smokers; whether or not elements of recruitment strategies have an impact on quit rates; and identifying those recruitment strategies (or different combinations of particular recruitment strategies with certain smoking cessation programmes) that work better for different population groups
