Assessing capacity and readiness to manage NCDs in primary care setting: Gaps and opportunities based on adapted WHO PEN tool in Zambia.
INTRODUCTION:Sub-Saharan Africa is experiencing an epidemiological transition as the burden of NCDs overtake communicable diseases. However, it is unknown what capacity and gaps exist at primary care level to address the growing burden of NCDs. This study aimed to assess the Zambian health system's capacity to address in NCDs, using an adapted WHO Essential Non Communicable Disease Interventions (WHO PEN) tool. METHODOLOGY:This was a cross-sectional facility survey in the three districts conducted from September 2017 to October 2017. We defined facility readiness along five domains: basic equipment, essential services, diagnostic capacity, counseling services, and essential medicines. For each domain, we calculated an index as the mean score of items expressed as percentage. These indices were compared to an agreed cutoff at 70%, meaning that a facility index or district index below 70% off was considered as 'not ready' to manage NCDs at that level. All analysis were performed using Stata 15 MP. RESULTS:There appeared to be wide heterogeneity between facilities in respect of readiness to manage NCDs. Only 6 (including the three 1st level hospitals) out of the 46 facilities were deemed ready to manage NCDs. Only the first level hospitals scored a mean index higher than the 70% cut off; With regard to medications needed to manage NCDs, urban and rural health facilities were comparably equipped. However, there was evidence that calcium channel blockers (p = 0.013) and insulin (p = 0.022) were more likely to be available in urban and semi-urban health facilities compared to rural facilities. CONCLUSION:Our study revealed gaps in primary health care capacity to manage NCDs in Zambia, with almost all health facilities failing to reach the minimum threshold. These results could be generalized to other similar districts in Zambia and the sub-region, where health systems remain focused on infectious rather than non-communicable Disease. These results should attract policy attention and potentially form the basis to review current approach to NCD care at the primary care level in Zambia and Sub-Saharan Africa

BACKGROUND: Tuberculosis diagnosis might be delayed or missed in children with severe pneumonia because this diagnosis is usually only considered in cases of prolonged symptoms or antibiotic failure. Systematic tuberculosis detection at hospital admission could increase case detection and reduce mortality. METHODS: We did a stepped-wedge cluster-randomised trial in 16 hospitals from six countries (Cambodia, Cameroon, C么te d'Ivoire, Mozambique, Uganda, and Zambia) with high incidence of tuberculosis. Children younger than 5 years with WHO-defined severe pneumonia received either the standard of care (control group) or standard of care plus Xpert MTB/RIF Ultra (Xpert Ultra; Cepheid, Sunnyvale, CA, USA) on nasopharyngeal aspirate and stool samples (intervention group). Clusters (hospitals) were progressively switched from control to intervention at 5-week intervals, using a computer-generated random sequence, stratified on incidence rate of tuberculosis at country level, and masked to teams until 5 weeks before switch. We assessed the effect of the intervention on primary (12-week all-cause mortality) and secondary (including tuberculosis diagnosis) outcomes, using generalised linear mixed models. The primary analysis was by intention to treat. We described outcomes in children with severe acute malnutrition in a post hoc analysis. This study is registered with ClinicalTrials.gov (NCT03831906) and the Pan African Clinical Trial Registry (PACTR202101615120643). FINDINGS: From March 21, 2019, to March 30, 2021, we enrolled 1401 children in the control group and 1169 children in the intervention group. In the intervention group, 1140 (97路5%) children had nasopharyngeal aspirates and 942 (80路6%) had their stool collected; 24 (2路1%) had positive Xpert Ultra. At 12 weeks, 110 (7路9%) children in the control group and 91 (7路8%) children in the intervention group had died (adjusted odds ratio [OR] 0路986, 95% CI 0路597-1路630, p=0路957), and 74 (5路3%) children in the control group and 88 (7路5%) children in the intervention group had tuberculosis diagnosed (adjusted OR 1路238, 95% CI 0路696-2路202, p=0路467). In children with severe acute malnutrition, 57 (23路8%) of 240 children in the control group and 53 (17路8%) of 297 children in the intervention group died, and 36 (15路0%) of 240 children in the control group and 56 (18路9%) of 297 children in the intervention group were diagnosed with tuberculosis. The main adverse events associated with nasopharyngeal aspirates were samples with blood in 312 (27路3%) of 1147 children with nasopharyngeal aspirates attempted, dyspnoea or SpO(2) less than 95% in 134 (11路4%) of children, and transient respiratory distress or SpO(2) less than 90% in 59 (5路2%) children. There was no serious adverse event related to nasopharyngeal aspirates reported during the trial. INTERPRETATION: Systematic molecular tuberculosis detection at hospital admission did not reduce mortality in children with severe pneumonia. High treatment and microbiological confirmation rates support more systematic use of Xpert Ultra in this group, notably in children with severe acute malnutrition. FUNDING: Unitaid and L'Initiative.
