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

Implementation of push notification using SignalR and WCF

Komunikacijo med strežniki in odjemalci lahko realiziramo na več načinov. Osnoven način je, da odjemalec povprašuje in strežnik odgovarja. V primeru, ko odjemalec ne ve, kdaj mu bo določena informacija na voljo, mora v intervalih spraševati strežnik. To je neučinkovito in boljša alternativa temu je, da strežnik obvešča odjemalce. Takemu načinu komunikacije pravimo potisno obveščanje. Implementacijo potisnega obveščanja smo izvedli s knjižnico SignalR in z ogrodjem WCF. Obe tehnologiji smo raziskali in ju primerjali. Za primerjavo tehnologij smo implementirali obveščanje o dogajanju v nadzoru različic kode. V našem primeru smo imeli dva tipa odjemalcev. En odjemalec je vmesnik za upravljanje z nadzorom različic kode Git. Ta obvešča strežnik o akcijah, ki se dogajajo nad kodo. Drugi tip odjemalca pa je namizna aplikacija in aplikacija za Windows Phone 8. Obe aplikaciji sprejemata obvestila o dogajanju v nadzoru različic kode, ki jim jih pošilja strežnik.Communication between servers and clients can be realised in several ways. A basic method is, when the client requests and the server responds. In case the client does not know, when the specific information will be available, it needs to ask the server in intervals. This is ineffective, and a better alternative is when the server informs the clients. Such communication is called server push. Server push was implemented with the SignalR library and with the WCF framework. Both technologies have been explored and compared. For comparison of technologies we implemented the notification of activity in revision control. In our case, we had two types of clients. The first client is an interface for managing the control of the Git revision control. It informs the server about actions, which take place over the code. The second client is a desktop application and an application for Windows Phone 8. Both applications receive notifications of activities in revision control
