Evaluation of Project Managers Understanding of Safety Management Plan on Construction Site.

Safety Management Plan (SMP) is a collection of documents that outline how the principal contractor will manage health and safety for employees, sub-contractors, suppliers, visitors and the general public. SMP formulates the approach to risk management and minimizes the potential human and financial loss to employers and employees alike. Thus, project managers are not expected to be health and safety experts, nor are they expected to conduct thorough worksite inspection. However, a basic appreciation of the safety and regulations issue most frequently encounter in construction site will help to ensure a safe work environment for employee and contractors, and minimize potential liability exposure. The objective of the paper is to determine the level of understanding of safety management system in workplace among the project managers of some selected sites in Kuala Lumpur. Structured or standardized questionnaires were used in the project manager’s interview at 5 different construction sites, on average, the score form the five sites as regard to project manager’s interview is 71.67%. In conclusion, the project managers have virtually all the potential and significant knowledge of the safety management plan practice in their sites, but still there was the need for improvement in the knowledge among the project managers as regard to the safety management system. The study therefore, recommended that in order to improve on the knowledge of safety management system on sites adequate training program should be incorporate into the organisational action plan for project managers. Such training program organised by National Institute of Occupational Safety and Health (NIOSH) Malaysia could be of great help in improving the knowledge of safety management system among the project manager.   Keywords Safety, Health, Management, Construction, Pla

Prevalence of HBsAg Among Prospective Blood Donors and Pregnant Women in Kebbi State, Nigeria

This study was aimed at determining the prevalence of Hepatitis B surface antigen (HBsAg) among prospective blood donors and pregnant women in Kebbi State, Nigeria. Three hundred and sixty one (361) apparently healthy prospective blood donors were recruited and screened for HBsAg using HBsAg rapid test kit. Those that tested positive for HBsAg (16.6%) were further assessed for liver function. The prevalence by gender was 23.4% and 13.1% for male and female subjects respectively. Prevalence by the three senatorial zones of the state is in the order Kebbi South (21.8%) > Kebbi North (15.1%) > Kebbi Central (13.6%). Subjects within the age group 26-30 years had the highest HBsAg prevalence of 20.9% compared to the other age groups. Single males have higher prevalence (26.1%) of HBV infection than their married counterparts (16.7%). Local government workers had highest prevalence (29.2%) followed by self-employed (27.6%) and then state government employees (14.3%). In females, occupational exposure (healthcare worker) and polygamy are risk factors with highest prevalence of 40.0% and 23.2% respectively. The levels of serum liver enzymes and bilirubin were significantly higher (p < 0.05) in HBsAg positive subjects compared to the HBsAg negative subjects. The reverse was, however, the case for albumin. Our result suggests that Kebbi State is one of the HBsAg hyper-endemic areas in Nigeria.Keywords: Hepatitis B, Prevalence, Liver function test, Kebbi State

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

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

U radu je prikazana definicija hidrograma otjecanja s najvažnijim parametrima koji najviše utječu na njegov oblik i definicija i osnovni principi teorije jediničnog hidrograma kao i statističke obrade podataka mjerenja oborina i protoka. Prema zadanim podacima na temelju izmjerenih vrijednosti dnevnih protoka izvora Rumin Veliki i Rumin Mali te njihovog zbroja u vremenskom razdoblju od 2000. do 2014. godine izvršena je hidrološka analiza odnosno izrada krivulje trajanja, te statistička obrada prosječnih vrijednosti srednjih, minimalnih i maksimalnih mjesečnih protoka.In this work is presented the definition of runoff hydrograms with the most important parameters which affect its shape. Also it is presented definition and basic principles of unit hydrogram theory and statistical processing of precipitation and flow measurement data. According to the given data, on the basis of the measured values of daily flows of the Rumin Veliki and Rumin Mali sources and their sum in the period from 2000 to 2014, a hydrological analysis was carried out and a duration curve was developed. Therefore, this work present statistical processing of average values of mean, minimum and maximum monthly flows

The ASOS Surgical Risk Calculator: development and validation of a tool for identifying African surgical patients at risk of severe postoperative complications

Background: The African Surgical Outcomes Study (ASOS) showed that surgical patients in Africa have a mortality twice the global average. Existing risk assessment tools are not valid for use in this population because the pattern of risk for poor outcomes differs from high-income countries. The objective of this study was to derive and validate a simple, preoperative risk stratification tool to identify African surgical patients at risk for in-hospital postoperative mortality and severe complications. Methods: ASOS was a 7-day prospective cohort study of adult patients undergoing surgery in Africa. The ASOS Surgical Risk Calculator was constructed with a multivariable logistic regression model for the outcome of in-hospital mortality and severe postoperative complications. The following preoperative risk factors were entered into the model; age, sex, smoking status, ASA physical status, preoperative chronic comorbid conditions, indication for surgery, urgency, severity, and type of surgery. Results: The model was derived from 8799 patients from 168 African hospitals. The composite outcome of severe postoperative complications and death occurred in 423/8799 (4.8%) patients. The ASOS Surgical Risk Calculator includes the following risk factors: age, ASA physical status, indication for surgery, urgency, severity, and type of surgery. The model showed good discrimination with an area under the receiver operating characteristic curve of 0.805 and good calibration with c-statistic corrected for optimism of 0.784. Conclusions: This simple preoperative risk calculator could be used to identify high-risk surgical patients in African hospitals and facilitate increased postoperative surveillance. © 2018 British Journal of Anaesthesia.
