Decentralizing Maternity Services to Increase Skilled Attendance at Birth and Antenatal Care Utilization in Rural Rwanda: A Prospective Cohort Study.

To evaluate the effectiveness of decentralizing ambulatory reproductive and intrapartum services to increase rates of antenatal care (ANC) utilization and skilled attendance at birth (SAB) in Rwanda. A prospective cohort study was implemented with one control and two intervention sites: decentralized ambulatory reproductive healthcare and decentralized intrapartum care. Multivariate logistic regression analysis was performed with primary outcome of lack of SAB and secondary outcome of ≥3 ANC visits. 536 women were entered in the study. Distance lived from delivery site significantly predicted SAB (p = 0.007), however distance lived to ANC site did not predict ≥3 ANC visits (p = 0.81). Neither decentralization of ambulatory reproductive healthcare (p = 0.10) nor intrapartum care (p = 0.40) was significantly associated with SAB. The control site had the greatest percentage of women receive ≥3 ANC visits (p < 0.001). Receiving <3 ANC visits was associated with a 3.98 times greater odds of not having SAB (p = 0.001). No increase in adverse outcomes was found with decentralization of ambulatory reproductive health care or intrapartum care. The factors that predict utilization of physically accessible services in rural Africa are complex. Decentralization of services may be one strategy to increase rates of SAB and ANC utilization, but selection biases may have precluded accurate analysis. Efforts to increase ANC utilization may be a worthwhile investment to increase SAB.

Technology to improve reliable access to oxygen in Western Uganda: study protocol for a phased implementation trial in neonatal and paediatric wards.

INTRODUCTION: Oxygen is an essential medicine for children and adults. The current systems for its delivery can be expensive and unreliable in settings where oxygen is most needed. FREO2 Foundation Australia has developed an integrated oxygen system, driven by a mains-powered oxygen concentrator, with the ability to switch automatically between low-pressure oxygen storage device and cylinder oxygen in power interruptions. The aim of this study is to assess the clinical impact and cost-effectiveness of expanding this system to 20 community and district hospitals and level IV facilities in Western Uganda. METHODS AND ANALYSIS: This will be a phased implementation with preintervention and postintervention comparison of outcomes. Standardised baseline data collection and needs assessment will be conducted, followed by implementation of the FREO2 Oxygen System in combination with pulse oximetry in 1-2 facilities per month over a 16-month period, with a total 23-month data collection period. The primary outcome will be the proportion of hypoxaemic children receiving oxygen pre and post oxygen system. Secondary outcomes will assess clinical, economic and technical aspects. Pre and post oxygen system primary and secondary outcomes will be compared using regression models and standard tests of significance. Useability will be quantitatively and qualitatively evaluated in terms of acceptability, feasibility and appropriateness, using standardised implementation outcome measure tools. ETHICS AND DISSEMINATION: Ethics approval was obtained from Mbarara University of Science and Technology (MUREC 1/7) and the University of Melbourne (2021-14489-13654-2). Outcomes will be presented to the involved facilities, and to representatives of the Ministry of Health, Uganda. Broader dissemination will include publication in peer-reviewed journals and academic conference presentations. TRIAL REGISTRATION NUMBER: ACTRN12621000241831.

Determinants of incidence and clearance of high-risk human papillomavirus infections in rural Rakai, Uganda.

BACKGROUND: We used self-administered vaginal swabs to assess the incidence and clearance of carcinogenic human papillomavirus (HPV) infections in rural Rakai, Uganda. METHODS: Women provided self-administered vaginal swab at annual home-based visits. Type-specific carcinogenic HPV incidence and clearance and risk factors were assessed. RESULTS: Carcinogenic HPV incidence was 17.3 per 100 person-years among HIV-positive women compared with 7.0 per 100 person-years among HIV-negative women (P < 0.001). HPV-51 had the highest incidence followed by HPV-16 (1.8 per 100 and 1.5 per 100 person-years, respectively). In multivariate model, HIV-positive women were twice as likely to have incident infection compared with HIV-negative women. Younger women were at higher risk for incident infection, as were women with higher lifetime and recent sexual partners, and high perception of AIDS. Married women were less likely to have incident infection. Approximately half of all carcinogenic HPV infections cleared over the study follow-up of 3 years. HPV-31, HPV-35, and HPV-16 had the lowest clearance (16.7%, 27.9%, and 38.3%, respectively). In multivariate model, HIV-positive, women over 30 years with higher HPV viral, burden and more lifetime sex partners were less likely to clear infections. CONCLUSIONS: Self-collected vaginal swabs provide accurate HPV exposure assessment for studying HPV exposure and epidemiology and can be an important tool for research in populations unwilling to undergo pelvic exam.

Prevalence and risk factors for High-Risk Human Papillomavirus (hrHPV) infection among HIV-infected and Uninfected Rwandan women: implications for hrHPV-based screening in Rwanda.

BACKGROUND: New World Health Organization guidelines recommend high-risk human papillomavirus (hrHPV) screen-and-treat strategies for cervical cancer prevention. We describe risk of, and risk factors for, testing hrHPV positive in a pilot study of hrHPV screen-and-treat conducted in Rwanda. METHODS: A total of 2,964 women, 1,289 HIV-infected (HIV [+]) and 1,675 HIV-uninfected (HIV [-]), aged 30-60 years and living in Rwanda were enrolled in 2010. Cervical specimens were collected and tested by careHPV, a DNA test for a pool of 14 hrHPV types. Prevalence with binomial 95% confidence intervals (95% CI) and determinants of testing hrHPV positive were calculated. RESULTS: hrHPV prevalence was higher in HIV [+] (31.8%, 95% CI = 29.2-34.4%) than HIV [-] women (8.2%, 95% CI = 6.7-9.8%; P < 0.0001). Among HIV [+] women, there was a significant trend (ptrend <0.001) of higher hrHPV prevalence with lower CD4 cell count, with the highest hrHPV prevalence among those with <200 CD4 cell counts (45.5%, 95% CI = 34.8-56.4%). In multivariate analysis of HIV [+] women, testing hrHPV positive was positively associated CD4 count of <200 cells/µL, history of 3 or more sexual partners, and history of using hormonal contraception, and negatively associated with older age. In HIV [-] women, testing hrHPV positive was negatively associated only with older age groups of 45-49 and 50-60 years and surprisingly was not associated with lifetime number of sexual partners. CONCLUSION: hrHPV prevalence is high in HIV [+], especially in women with the lowest CD4 cell counts, which may have implications for utilizing hrHPV-based screening strategies such as screen-and-treat in these high-risk subgroups.

Comparability of self-collected vaginal swabs and physician-collected cervical swabs for detection of human papillomavirus infections in Rakai, Uganda.

OBJECTIVE: The objective of this study was to compare human papillomavirus (HPV) DNA testing between self-administered vaginal swabs and physician-administered cervical swabs in women from rural Rakai District, Uganda. STUDY DESIGN: Between 2002 and 2003, women from a population-based cohort participated in an HPV study. Women collected self-administered vaginal swabs and were also offered a pelvic examination, which included physician-collected cervical samples. METHODS: Hybrid-capture 2 was used to determine carcinogenic HPV status. Polymerase chain reaction was used to determine HPV genotypes. Unweighted kappa statistics were used to determine agreement. RESULTS: Compliance with self-collected swabs was > or =86%; however, only 51% accepted a pelvic examination. Carcinogenic HPV prevalence was 19% in self-collected and 19% in physician-collected samples. Agreement among paired observations was 92% with a kappa of 0.75. Kappa between self- and physician-collected samples was similar in HIV strata (k = 0.71 and 0.75 for HIV-positive and HIV-negative, respectively). DISCUSSION: In this community-based setting, detection of carcinogenic HPV was comparable among self- and physician-administered samples. Self-collection is a feasible and accurate means of obtaining HPV samples from women in resource-poor settings or persons reluctant to undergo a pelvic examination.
