Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
JAK2 V617F mutation in essential thrombocythemia: correlation with clinical characteristics, response to therapy and long-term outcome in a cohort of 275 patients
The JAK2(V617F) mutation occurs in 50% of patients with essential thrombocythemia (ET). We investigated the correlation between the JAK2(V617F) mutation and clinical and laboratory characteristics, thrombohemorrhagic risk and incidence of disease evolution in 275 patients with ET followed for a median follow-up of 7 years. JAK2(V617F) mutation was detected in 175 patients (64%), of whom 173 were heterozygous. Patients with the mutation were older and displayed higher hemoglobin and hematocrit levels, but lower platelet count. Cytotoxic treatment requirement was similar in the two groups, but patients with the mutation showed better responses. Incidence of thrombosis and disease evolution was comparable. JAK2 mutational status assessment was valuable to distinguish two populations of patients with ET, showing distinctive hematologic and clinical features
A risk prediction score for invasive mold disease in patients with hematological malignancies.
BACKGROUND: A risk score for invasive mold disease (IMD) in patients with hematological malignancies could facilitate patient screening and improve the targeted use of antifungal prophylaxis. METHODS: We retrospectively analyzed 1,709 hospital admissions of 840 patients with hematological malignancies (2005-2008) to collect data on 17 epidemiological and treatment-related risk factors for IMD. Multivariate regression was used to develop a weighted risk score based on independent risk factors associated with proven or probable IMD, which was prospectively validated during 1,746 hospital admissions of 855 patients from 2009-2012. RESULTS: Of the 17 candidate variables analyzed, 11 correlated with IMD by univariate analysis, but only 4 risk factors (neutropenia, lymphocytopenia or lymphocyte dysfunction in allogeneic hematopoietic stem cell transplant recipients, malignancy status, and prior IMD) were retained in the final multivariate model, resulting in a weighted risk score 0-13. A risk score of 5%) of IMD, with a negative predictive value (NPV) of 0.99, (95% CI 0.98-0.99). During 2009-2012, patients with a calculated risk score at admission of 6 (0.9% vs. 10.6%, P <0.001). CONCLUSION: An objective, weighted risk score for IMD can accurately discriminate patients with hematological malignancies at low risk for developing mold disease, and could possibly facilitate "screening-out" of low risk patients less likely to benefit from intensive diagnostic monitoring or mold-directed antifungal prophylaxis
Melphalan-prednisone versus alternating combination VAD/MP or VND/MP as primary therapy for multiple myeloma: final analysis of a randomized clinical study
In the absence of a cure for multiple myeloma (MM) with standard-dose therapy, any strategy that can be expected to increase tumor reduction and to extend survival duration is likely to be of clinical relevance. The primary end-point of the present study was to investigate whether the alternating combination of vincristine-doxorubicin-dexamethasone (VAD) and melphalan-prednisone (MP) or vincristine-mitoxantrone-dexamethasone (VND) and MP could improve the clinical outcome of MM patients thus treated in comparison with those receiving MP alone

Analysis of risk score discrimination and optimal cut-off for invasive model disease risk.
<p>(a) Receiver-operator curve (ROC) analysis plot of the true positives plotted as a function of the false-positives (100-specificity) at different cutoffs of the risk score. Gray bands represent the 95% CI of the plot. The dotted line represents a reference line no discrimination for invasive mold disease (aROC=0.5). The <i>P</i> value is the probability that the aROC differs significantly from aROC=0.5; (b) Plot of sensitivity and specificity versus risk score. The highest sensitivity (true positive rate) and specificity (true negative rate) meet at a score just below 6, suggesting a criterion value of > 6.</p
Impact of posaconazole prophylaxis on the incidence and mortality of invasive mold disease in the 2009-2012 validation cohort.
<p>(a) Cumulative incidence of invasive mold disease in patients with calculated risk scores <6 or > 6. <i>P</i> value determined by Chi-square test. (b) Kaplan-Meier analysis of crude mortality in patients with acute myelogenous leukemia or myelodysplastic syndrome undergoing remission-induction chemotherapy by status of posaconazole prophylaxis. Each patient is analyzed only once and was classified as alive or dead at the time of discharge (censored) or death by day +42 after admission. <i>P</i> value was determined by the Mantel-Cox (log-rank) test.</p
Prospective, randomized study of single compared with double autologous stem-cell transplantation for multiple myeloma: Bologna 96 clinical study
Purpose: We performed a prospective, randomized study of single (arm A) versus double (arm B) autologous stem-cell transplantation (ASCT) for younger patients with newly diagnosed multiple myeloma (MM). Patients and Methods: A total of 321 patients were enrolled onto the study and were randomly assigned to receive either a single course of high-dose melphalan at 200 mg/m2 (arm A) or melphalan at 200 mg/m2 followed, after 3 to 6 months, by melphalan at 120 mg/m2 and busulfan at 12 mg/kilogram (arm B). Results: As compared with assignment to the single-transplantation group (n = 163 patients), random assignment to receive double ASCT (n = 158 patients) significantly increased the probability to attain at least a near complete response (nCR; 33% v 47%, respectively; P = .008), prolonged relapse-free survival (RFS) duration of 18 months (median, 24 v 42 months, respectively; P < .001), and significantly extended event-free survival (EFS; median, 23 v 35 months, respectively; P = .001). Administration of a second transplantation and of novel agents for treating sequential relapses in up to 50% of patients randomly assigned to receive a single ASCT likely contributed to prolong the survival duration of the whole group, whose 7-year rate (46%) was similar to that of the double-transplantation group (43%; P = .90). Transplantation-related mortality was 3% in arm A and 4% in arm B (P = .70). Conclusion: In comparison with a single ASCT as up-front therapy for newly diagnosed MM, double ASCT effected superior CR or nCR rate, RFS, and EFS, but failed to significantly prolong overall survival. Benefits offered by double ASCT were particularly evident among patients who failed at least nCR after one autotransplantation. © 2007 by American Society of Clinical Oncology
