Spatiotemporal dynamics and prevention strategies of cervical cancer incidence in Addis Ababa, Ethiopia: an ecological study

Objective This study analysed the spatial and temporal patterns of cervical cancer incidence in Addis Ababa from 2012 to 2021. Design An ecological study was conducted from 1 September to 30 November 2023 to examine the spatiotemporal trends of cervical cancer incidence. Setting The research was conducted in Addis Ababa, the capital city of Ethiopia. Participants Included were all patients with clinically and/or histopathologically confirmed diagnoses of cervical cancer. Data analysis The study employed advanced analytical tools including R programming, Quantum Geographic Information System V.3.36.0, GeoDa V.1.2.2 and System for Automated Geoscientific Analyses GIS V.9.3.2. Techniques such as Bayesian empirical testing with a block weighting matrix for hotspot identification, Global Moran’s I for spatial autocorrelation, nearest neighbour imputation and universal Kriging interpolation were used to manage data gaps. Joinpoint trend analysis and direct age-standardised incidence rate (ASIR) using the Segi’s World standard population was applied to compare trends across subcities. A statistical significance threshold was set at p<0.05. Results Between 2012 and 2021, a total of 2435 new cervical cancer cases were recorded in the Addis Ababa City Population-based Cancer Registry, with significant spatial clustering observed in Nifas Silk Lafto, Bole, Kirkos as well as parts of Gulele and Yeka sub cities (z score>1.96) in 2018. The citywide age-standardised incidence rate varied from 19 to 26 cases per 100 000 women-years during 2013 and 2016, respectively. Subcity trends varied significantly, with increases and decreases noted in Akaki Kality and Kolfe Keraniyo over different periods while Bole subcity showed modest increase at 4.2% APC (95% CI: 0.6% to 7.9%; p=0.026). Conclusion The study highlights substantial fluctuations in ASIR and significant geographic disparities in cervical cancer throughout Addis Ababa. To address these challenges, the implementation of school-based human papillomavirus vaccination programmes, alongside targeted interventions, active campaigns and sustained surveillance, is critical. These strategies are essential to effectively reduce the cervical cancer burden and improve health outcomes in the community.

Validation of the Amharic version of perceived access to healthcare services for patients with cervical cancer in Ethiopia: A second-order confirmatory factor analysis

BackgroundAccessing healthcare services is a multifaceted phenomenon involving various elements, encompassing the demand, identification, reach, and utilization of healthcare needs. The literature offers methods for capturing patients’ perceptions of healthcare access. However, to accurately measure patient perceptions, it is imperative to ensure the validity and reliability of such instruments by designing and implementing localized language versions.AimThe primary aim of this study was to validate the Amharic version of the perceived access to health-care services among patients diagnosed with cervical cancer in Ethiopia.MethodA cross-sectional study was conducted among cervical cancer patients at oncology centers in Addis Ababa, Ethiopia. A consecutive sampling approach was used and data collection took place from January 1 to March 30, 2023. Following initial validation and pretesting, a KoboCollect mobile phone application was employed for data collection. Subsequently, the collected data underwent cleaning in Microsoft Excel and analysis through Amos software v.26 and R programming. Various validity and reliability tests, such as content validity, convergent validity, face validity, divergent validity, known-group validity, and reliability tests, were executed. A second-order confirmatory factor analysis was developed to calculate incremental model fit indices, including CFI and TLI, along with absolute measures, namely SRMR and RMSEA.ResultsA total of 308 participants were involved in the study, with 202 (65.6%) being patients referred from outside Addis Ababa. The initial evaluation of content validity by expert panels indicated that all criteria were met, with a CVR range of 0.5 to 1, I-CVI values ranging from 0.75 to 1, an S-CVI value of 0.91, and face validity values ranging from 2.4 to 4.8. The internal consistency of items within the final constructs varied from 0.76 to 0.93. Convergent, known-group, and most divergent validity tests fell within acceptable fit ranges. Common incremental fit measures for CFI and TLI were achieved with corresponding values of 0.95 and 0.94, respectively. The absolute fit measures of SRMR and RMSEA were 0.04 and 0.07, indicating good and moderate fit, respectively.ConclusionThe study indicated a high internal consistency and validity of items with good fit to the data, suggesting potential accuracy of the domains. A five-domain structure was developed which enables adequate assessment of perceived access to health-care services of patients with cervical cancer in Ethiopia. We suggest that the tool can be utilized in other patient populations with a consideration of additional constructs, such as geographic accessibility.

Association between delayed initiation of treatment indications and survival in patients with cervical cancer: A systematic review and meta-analysis protocol

Background Cervical cancer is a growing public health problem globally. Despite the availability of management options, the progression of the disease as a function of waiting time may challenge the effort to attain a desired outcome. There is a conflicting report on the role of waiting time to initiate an appropriate treatment in improving patients’ survival. Objective This review aims to evaluate the association between delayed time to initiate any treatment indication with survival in patients with cervical cancer. Methods An internet-based literature search will be performed using text words, MESH terms and truncated words in databases, namely MEDLINE, Cochrane CENTRAL, EMBASE, Web of Science and Scopus. Grey literature searches in Google Scholar, Networked Digital Library of Theses and Dissertations (NDLTD) and Dissertations and Theses Global will be made. All articles published until 30th of December 2021 on human subjects will be searched without a language restriction. Studies which fulfil the inclusion criteria will be screened in full reading, selected, appraised and assessed for methodological quality by two independent reviewers. Data on participants, study methods, interventions, and outcomes will be abstracted. Included studies will be pooled for meta-analysis. Microsoft-Excel and R packages will be employed to carry out the statistical analysis. Heterogeneity will be assessed using Cochrane Q statistic, Tau2, and I2. Results will be reported as a function of 4-week delay in treatment initiation and the corresponding hazard ratio (HR) at 95% confidence interval. Statistical significance will be considered at P<0.05. Trial registration PROSPERO registration number: CRD42022299689.
