“…Where the PH assumption was violated, some studies excluded individual predictors violating the assumption [ 54 ] or reported odds ratio rather than hazard ratios [ 55 ] or censored the analysis at 28 days for a study with follow-up of 12 weeks to meet the PH assumption [ 56 ]. Only one study [ 51 ] among the 3 that performed competing risk analysis mentioned testing the underlying PH assumption but did not report the test results. The two studies that used parametric PH methods tested the PH assumption using the Schoenfeld residual test and reported the results [ 47 , 48 ].…”

“…The two studies reporting parametric accelerated failure time [49,50] and 69 studies performing Cox (67 studies) and parametric (2 studies) proportional hazard models reported time ratios (TR) and hazard ratios (HR) as the measure of effect respectively. Two of the three studies that performed competing risk analysis reported sub-distribution hazard ratios (SHR) [45,51] while the other study reported HR [52]. All 74 studies reported 95% confidence intervals as measure of effect uncertainty (Table 3).…”

Background Survival analyses methods (SAMs) are central to analysing time-to-event outcomes. Appropriate application and reporting of such methods are important to ensure correct interpretation of the data. In this study, we systematically review the application and reporting of SAMs in studies of tuberculosis (TB) patients in Africa. It is the first review to assess the application and reporting of SAMs in this context. Methods Systematic review of studies involving TB patients from Africa published between January 2010 and April 2020 in English language. Studies were eligible if they reported use of SAMs. Application and reporting of SAMs were evaluated based on seven author-defined criteria. Results Seventy-six studies were included with patient numbers ranging from 56 to 182,890. Forty-three (57%) studies involved a statistician/epidemiologist. The number of published papers per year applying SAMs increased from two in 2010 to 18 in 2019 (P = 0.004). Sample size estimation was not reported by 67 (88%) studies. A total of 22 (29%) studies did not report summary follow-up time. The survival function was commonly presented using Kaplan-Meier survival curves (n = 51, (67%) studies) and group comparisons were performed using log-rank tests (n = 44, (58%) studies). Sixty seven (91%), 3 (4.1%) and 4 (5.4%) studies reported Cox proportional hazard, competing risk and parametric survival regression models, respectively. A total of 37 (49%) studies had hierarchical clustering, of which 28 (76%) did not adjust for the clustering in the analysis. Reporting was adequate among 4.0, 1.3 and 6.6% studies for sample size estimation, plotting of survival curves and test of survival regression underlying assumptions, respectively. Forty-five (59%), 52 (68%) and 73 (96%) studies adequately reported comparison of survival curves, follow-up time and measures of effect, respectively. Conclusion The quality of reporting survival analyses remains inadequate despite its increasing application. Because similar reporting deficiencies may be common in other diseases in low- and middle-income countries, reporting guidelines, additional training, and more capacity building are needed along with more vigilance by reviewers and journal editors.

Countries affected by conflict often experience the deterioration of health system infrastructure and weakened service delivery. Evidence suggests that healthcare services that leverage local community dynamics may ameliorate health system-related challenges, however, little is known about implementing these interventions in contexts where formal delivery of care is hampered subsequent to conflict. We reviewed the evidence on community health worker (CHW)-delivered healthcare in conflict-affected settings and synthesized reported information on the effectiveness of interventions and characteristics of care delivery. We conducted a systematic review of studies in OVID MedLine, Web of Science, Embase, Scopus, CINHAL, and Google Scholar databases. Included studies (1) described a context that is post-conflict, conflict-affected, or impacted by war or crisis; (2) examined the delivery of healthcare by CHWs in the community; (3) reported a specific outcome connected to CHWs or community-based healthcare (CBHC); (4) were available in English, Spanish, or French; and (5) were published between 1 January 2000 and 6 May 2021. We identified 1976 articles, of which 55 met the inclusion criteria. Nineteen countries were represented, and five categories of disease were assessed. Evidence suggests that CHW interventions not only may be effective but also efficient in circumventing the barriers associated with access to care in conflict-affected areas. CHWs may leverage their physical proximity and social connection to the community they serve to improve care by facilitating access to care, strengthening disease detection, and improving adherence to care. Specifically, case management (e.g. integrated community case management) were was documented to be effective in improving a wide range of health outcomes and should be considered as a strategy to reduce barrier to access in hard-to-reach areas. Furthermore, task-sharing strategies have been emphasized as a common mechanism for incorporating CHWs into health systems

Treatment outcomes of TB‐infected individuals attending public sector primary care clinics in rural Liberia from 2015 to 2017: a retrospective cohort study

Abstract: In challenging environments, LTFU can be reduced by CHW accompaniment and socio-economic assistance to patients with TB. Approaches are needed to improve cure verification in young patients and reduce mortality.
