    Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

    La valorisation de la formation MiocĂšne dans la rĂ©gion de Taza, reprĂ©sentĂ©e par les calcarĂ©nites, a Ă©tĂ© menĂ©e selon deux axes ; tout d’abord une Ă©tude gĂ©ologique, couplĂ©e Ă  des Ă©tudes de terrain nous a permis d’évaluer l’épaisseur de la formation, une carte d’épaisseur a Ă©tĂ© dressĂ©e Ă  cet effet. L’étude gĂ©otechnique de ces matĂ©riaux rĂ©vĂšle que ces calcarĂ©nites ont des qualitĂ©s intĂ©ressantes pour des utilisations industrielles. En effet, en se basant sur les diffĂ©rents tests de duretĂ© (Los Angeles et Micro Duval), la rĂ©sistance Ă  la rupture et la porositĂ© de nos quatre Ă©chantillons, une valeur ajoutĂ©e industrielle peut leur ĂȘtre attribuĂ©e dans beaucoup de domaines, comme: -Graves non traitĂ©s pour couches de fondations pour les chaussĂ©es ou grave bitumeux de fondation; -Ajouts dans les bĂ©tons; -Roche marbriĂšre et pierre de façade. En fin, sur la base de ces Ă©tudes gĂ©ologiques et gĂ©otechniques, on peut considĂ©rer que les calcarĂ©nites de la rĂ©gion de Taza rĂ©pondent Ă  l’ensemble des critĂšres d’une exploitation industrielle. The valuation of the Miocene formation in the Taza region, represented by calcarenites, was conducted according two axes; first geological survey, coupled with field studies allowed us to evaluate the thickness of the formation, a thickness map was derived from this purpose. The geotechnical study of these materials reveals that these calcarenites have interesting qualities for industrial uses. Indeed, based on the different hardness tests (Los Angeles and Micro Duval), the tensile strength and porosity of our four samples, an industrial added value can be attributed to them in many areas, such as: - Untreated Graves for layers of foundations for pavements or bituminous serious foundation; - Additions in concrete; - Roche marble and stone facade. Finally, on the basis of geological and geotechnical studies, we can consider that the calcarenites of the Taza region meet all criteria of an industrial operation
