Frequent Exposure

The construction industry is a risk-prone industry where projects are implemented in a dynamic environment with frequent exposure to various uncertainties. A construction contract is a document that allocates the risks associated with a construction project among the project stakeholders. Guaranteed Maximum Price (GMP) contracts have become popular as a project delivery method because they provide the client with a high degree of cost certainty through a fixed price cap that the contractor cannot exceed. However, most of the GMP projects are risky. Thus, the significant risk factors of GMP projects have to be identified to ensure their successful completion. This study, therefore, aimed to identify and rank the most significant risk factors present in GMP contracts. The study adopted a quantitative approach, which included a Delphi survey conducted in two rounds and a statistical analysis of the survey data. The most significant risk factors associated with GMP contracts were ranked according to their impact on the projects and their probability of occurrence (severity). Poorly defined scope of work and design changes were found to be the most significant risk factors associated with GMP contracts. The other significant risk factors of the projects are related to the scope of work, design, documentation, unfamiliarity with the GMP concept, agreed GMP value, and financial failures of the client and contractor.

<strong>Objective:</strong> We aimed to evaluate the risk factors associated with acute renal failure in patients who underwent coronary artery bypass surgery.<br /><strong>Methods:</strong> One hundred and six patients who developed renal failure after coronary artery bypass grafting (CABG) constituted the study group (RF group), while 110 patients who did not develop renal failure served as a control group <br />(C group). In addition, the RF group was divided into two subgroups: patients that were treated with conservative methods without the need for hemodialysis (NH group) and patients that required hemodialysis (HR group). Risk factors associated with renal failure were investigated.<br /><strong>Results:</strong> Among the 106 patients that developed renal failure (RF), 80 patients were treated with conservative methods without any need for hemodialysis (NH group); while <br />26 patients required hemodialysis in the postoperative period (HR group). The multivariate analysis showed that diabetes mellitus and the postoperative use of positive inotropes and adrenaline were significant risk factors associated with development of renal failure. In addition, carotid stenosis and postoperative use of adrenaline were found to be significant risk factors associated with hemodialysis-dependent renal failure (P &lt; .05). The mortality in the RF group was determined as 13.2%, while the mortality rate in patients who did not require hemodialysis and those who required hemodialysis was 6.2% and 34%, respectively.<br /><strong>Conclusion:</strong> Renal failure requiring hemodialysis after CABG often results in high morbidity and mortality. Factors affecting microcirculation and atherosclerosis, like diabetes mellitus, carotid artery stenosis, and postoperative vasopressor use remain the major risk factors for the development of renal failure.<br /><br />

The Impact

The prevalence of enterococcal infection, especially E. faecium, is increasing, and the issue of the impact of vancomycin resistance on clinical outcomes is controversial. This study aimed to investigate the clinical outcomes of infection caused by E. faecium and determine the risk factors associated with mortality. This retrospective study was performed at the Phramongkutklao Hospital during the period from 2014 to 2018. One hundred and forty-five patients with E. faecium infections were enrolled. The 30-day and 90-day mortality rates of patients infected with vancomycin resistant (VR)-E. faecium vs. vancomycin susceptible (VS)-E. faecium were 57.7% vs. 38.7% and 69.2% vs. 47.1%, respectively. The median length of hospitalization was significantly longer in patients with VR-E. faecium infection. In logistic regression analysis, VR-E. faecium, Sequential Organ Failure Assessment (SOFA) scores, and bone and joint infections were significant risk factors associated with both 30-day and 90-day mortality. Moreover, Cox proportional hazards model showed that VR-E. faecium infection (HR 1.91; 95%CI 1.09–3.37), SOFA scores of 6–9 points (HR 2.69; 95%CI 1.15–6.29), SOFA scores ≥ 10 points (HR 3.71; 95%CI 1.70–8.13), and bone and joint infections (HR 0.08; 95%CI 0.01–0.62) were significant risk factors for mortality. In conclusion, the present study confirmed the impact of VR-E. faecium infection on mortality and hospitalization duration. Thus, the appropriate antibiotic regimen for VR-E. faecium infection, especially for severely ill patients, is an effective strategy for improving treatment outcomes.

Abstract Background: Dengue Fever (DF) is a significant health problem in Yemen especially in the coastal areas. On November 6, 2018, Taiz governorates surveillance officer notified the Ministry of Public Health and Population on an increase in the number of suspected DF in Al Qahirah and Al Mudhaffar districts, Taiz governorate. On November 7, 2018, Field Epidemiology Training Program sent a team to perform an investigation. The aims were to confirm and describe the outbreak by person, place and time in Taiz governorate, and identify its risk factors.Methodology: Descriptive and case-control study (1:2 ratio) were conducted. WHO case definition was used to identify cases in Al Qahirah or Al Mudhaffar districts during August-November 2018. Control was selected from the same districts who did not suffer from DF. Predesigned questionnaire was used to collect data related to sociodemographic, behavioral and environmental characteristics. Bivariate and multivariate backward stepwise analyses were used. The adjusted odds ratios (aOR) and 95% confidence intervals (95%CI) were calculated. A P value < 0.05 was considered as the cut point for statistically significant. Epi info version 7.2 was used.Results: A total of 50 DF cases were found. Almost 52% were males and 76% were <30 years of age. The overall attack rate was 1/10,000 of the population. Case fatality rate was 4%. In multivariate analysis, not working (aOR = 26.6, 95% CI: 6.8–104.7), not using mosquito repellent (aOR = 13.9, 95% CI:1.4–136.8), wearing short sleeves/pants (aOR = 27.3, 95% CI: 4.8–156.8), poor sanitation (aOR = 5.4, 95% CI: 1.4–20.3), presence of outdoor trees (aOR = 13.2, 95% CI: 2.8–63.0) and houses without window nets (aOR = 15.7, 95% CI: 3.9–63.4) were statistically significant risk factors associated with DF outbreak. Eleven 11 (58%) of blood samples were positive for DF IgM.Conclusions: DF outbreak in Al Qahirah and Al Mudhaffar districts, Taiz governorate was confirmed. This study provides evidence-based information regarding the identified risk factors that contributed to the occurrence of this outbreak. Raising community awareness on the importance of personal protection measures and improving the sanitation services are strongly recommended.

Central Catheters

BACKGROUNDPeripherally inserted central catheters (PICCs) are associated with central-line–associated bloodstream infections (CLABSIs). However, no tools to predict risk of PICC-CLABSI have been developed.OBJECTIVETo operationalize or prioritize CLABSI risk factors when making decisions regarding the use of PICCs using a risk model to estimate an individual’s risk of PICC-CLABSI prior to device placement.METHODSUsing data from the Michigan Hospital Medicine Safety consortium, patients that experienced PICC-CLABSI between January 2013 and October 2016 were identified. A Cox proportional hazards model with robust sandwich standard error estimates was then used to identify factors associated with PICC-CLABSI. Based on regression coefficients, points were assigned to each predictor and summed for each patient to create the Michigan PICC-CLABSI (MPC) score. The predictive performance of the score was assessed using time-dependent area-under-the-curve (AUC) values.RESULTSOf 23,088 patients that received PICCs during the study period, 249 patients (1.1%) developed a CLABSI. Significant risk factors associated with PICC-CLABSI included hematological cancer (3 points), CLABSI within 3 months of PICC insertion (2 points), multilumen PICC (2 points), solid cancers with ongoing chemotherapy (2 points), receipt of total parenteral nutrition (TPN) through the PICC (1 point), and presence of another central venous catheter (CVC) at the time of PICC placement (1 point). The MPC score was significantly associated with risk of CLABSI (P<.0001). For every point increase, the hazard ratio of CLABSI increased by 1.63 (95% confidence interval, 1.56–1.71). The area under the receiver-operating-characteristics curve was 0.67 to 0.77 for PICC dwell times of 6 to 40 days, which indicates good model calibration.CONCLUSIONThe MPC score offers a novel way to inform decisions regarding PICC use, surveillance of high-risk cohorts, and utility of blood cultures when PICC-CLABSI is suspected. Future studies validating the score are necessary.Infect Control Hosp Epidemiol2017;38:1155–1166

Risk Of Death

IntroductionPatients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may develop coronavirus disease 2019 (COVID-19). Risk factors associated with death vary among countries with different ethnic backgrounds. We aimed to describe the factors associated with death in Mexicans with confirmed COVID-19.Material and methodsWe analysed the Mexican Ministry of Health’s official database on people tested for SARS-CoV-2 infection by real-time reverse transcriptase–polymerase chain reaction (rtRT-PCR) of nasopharyngeal fluids. Bivariate analyses were performed to select characteristics potentially associated with death, to integrate a Cox-proportional hazards model.ResultsAs of May 18, 2020, a total of 177,133 persons (90,586 men and 86,551 women) in Mexico received rtRT-PCR testing for SARS-CoV-2. There were 5332 deaths among the 51,633 rtRT-PCR-confirmed cases (10.33%, 95% CI: 10.07–10.59%). The median time (interquartile range, IQR) from symptoms onset to death was nine days (5–13 days), and from hospital admission to death 4 days (2–8 days). The analysis by age groups revealed that the significant risk of death started gradually at the age of 40 years. Independent death risk factors were obesity, hypertension, male sex, indigenous ethnicity, diabetes, chronic kidney disease, immunosuppression, chronic obstructive pulmonary disease, age > 40 years, and the need for invasive mechanical ventilation (IMV). Only 1959 (3.8%) cases received IVM, of whom 1893 were admitted to the intensive care unit (96.6% of those who received IMV).ConclusionsIn Mexico, highly prevalent chronic diseases are risk factors for death among persons with COVID-19. Indigenous ethnicity is a poorly studied factor that needs more investigation.

Background: Surgical site infection (SSI) is defined as infection occurring within 30 days after a surgical procedure and affecting either the incision or deep tissues at the operation site. SSIs are the most common nosocomial infections, accounting for 38% of hospital-acquired infections. Despite the advances in SSI control practices, SSIs remain common causes of morbidity and mortality among hospitalized patients. This study was undertaken with an objective to determine and analyze the risk factors associated with cesarean section SSIs.Methods: The study was carried out at Medical College and SSG Hospital, Baroda. After obtaining informed consent to be a part of the study, 140 subjects having cesarean section SSI as per the definition, were included as cases in the study. The controls (140) were also selected from the hospital subjects. The primary post-operative care was similar for the cases as well as controls. For patients who had SSI, samples of discharge from the cesarean section wound were collected and transported for culture. Antibiotics were given accordingly. Details about patient characteristics and outcomes were collected in the proforma for cases and controls and data analyzed.Results: The cesarean section SSI rate was 4.78%. Of the parameters studied, maternal age, parity, gestational age, HIV status, meconium stained amniotic fluid, amount of blood loss, previous surgery, duration of surgery were not associated with cesarean section SSI.Conclusions: Number of antenatal care (ANC) visits, haemoglobin, total white blood cells (WBC) count, pre eclampsia, premature rupture of membranes (PROM), non-progression in 2nd stage and subcutaneous tissue thickness were the independent significant risk factors associated with post-cesarean SSI.

Purpose – The purpose of this paper is to extend the body of knowledge on healthcare facilities management (FM) by investigating the risks associated with outsourcing of FM services in hospitals. Design/methodology/approach – The paper relied on two strands of methodology common with pragmatic research. Questionnaire survey (QS) used data from 208 respondents representing ten hospitals while three out of the ten hospitals involved in the QS were selected based on their willingness to enter the case study (CS) interview. Data collected were analysed using descriptive and inferential statistics for QS and using narrative techniques by discussing themes, sub-themes for the CS. Findings – Findings established 24 out of the 35 risk factors as critical, four factors as somehow critical, and five factors as not critical. Besides, nine risk factors were found to be significantly loaded on the five risk categories. The rank analysis also revealed that the top five critical risk factors are: inexperience and lack of requisite skills; possibility of fraud by vendor; financial failure of chosen vendor; vendor opportunism; and fall in morale of employees. Originality/value – The study provides an unambiguous contribution to exiting body of knowledge on outsourcing risks as it relates to healthcare FM. It reinforces the theory that risks exist in any form of relationship but developed a distinct body of factors associated with outsourcing of FM services particularly from the context of Nigeria’s public healthcare sector.

Background: Subclinical diastolic dysfunction is defined as echocardiographic evidence of left ventricular diastolic dysfunction and normal ejection fraction (EF) without congestive heart failure (HF) symptoms/diagnosis. Our study, for the first time, sought to examine risk factors associated with progression from subclinical diastolic dysfunction to overt HF in a large multiethnic population. Methods: The study population included patients with asymptomatic diastolic dysfunction and EF ≥ 50% assessed by transthoracic echocardiogram between 2003 and 2008 at Montefiore Medical Center, Bronx, NY. Patients with preexisting HF, valvular heart disease or atrial fibrillation prior were excluded. The end point was the development of HF by September 1, 2013. Multivariable adjusted Cox proportional hazards models, determined by stepwise selection method, were performed to examine risk factors associated with the development of HF. All analyses were also performed with adjustment and stratification of race. Results: A total of 7,879 patients, with 21% European Americans (EA), 36% African Americans (AA), 31% Hispanics, and 12% others or unknown, were included in the analysis. Mean follow up time was 6.3 years. Mean age of the cohort was 68±12, with 63% women. The overall cumulative probability of development of HF was 17% (19% in EA, 17% in AA, 19% in Hispanic patients) during the follow up period. In multivariable Cox proportional hazard regression analysis, renal disease (hazard ratio (HR)=1.6, 95% confidence interval (CI) 1.3-2.0, P<0.001) and hemoglobin levels (HR=0.9, 95% CI 0.9-1.0, P=0.001) were significantly associated with the development of HF in overall population. In stratification analysis, age (P=0.012) and hypertension (P=0.007) were independent risk factors for HF in Hispanic patients, but not in EA and AA. Conclusions: In a large multiethnic population with subclinical diastolic dysfunction, renal disease and hemoglobin levels were independently associated with development of HF in overall population.. Age and hypertension were significant risk factors for HF only in Hispanic patients. These results may have important implications in preventing the development of HF from subclinical stage.

ackground: Tuberculosis (TB) is a major public health problem, including Thailand. Anti-TB drugs are very effective treatment, but they can cause hepatotoxicity. Data on the prevalence of anti-TB drug-induced hepatotoxicity (DIH), as well as the contributing risk factors, are scarce in Thailand. Objective: To measure the prevalence and identify risk factors associated with first-line drugs (FLD) induced hepatoxicity in TB patients. Materials and Methods: The present study was a retrospective study design in TB clinic of Suratthani Hospital, in Southern Thailand. All patients diagnosed with TB and received FLD between January and December 2017, were eligible for the study. Hepatoxicity defined as the following criteria: serum aspartate aminotransferase (AST) or alanine aminotransferase (ALT) levels >5x upper limit of normal (ULN) without symptoms, or AST or ALT >3x ULN with clinical symptoms. Results: Of all the 198 TB cases, 18 were identified as DIH. Prevalence of DIH was 9.1%. Hepatitis after FLD was independently associated with age>60 years (adjusted OR [aOR] 28.49, 95% CI 2.68 to 302.95, p=0.005) and serum albumin <3.5 g/dL (aOR 20.97, 95% CI 2.11 to 208.51, p=0.009). Conclusion: Age of more than 60 years and low serum albumin of less than 3.5 g/dL were significant risk factors associated with first-line anti-TB drugs induced hepatoxicity.

Abstract Diversified farms are operations that raise a variety of crops and/or multiple species of livestock, with the goal of utilising the products of one for the growth of the other, thus fostering a sustainable cycle. This type of farming reflects consumers' increasing demand for sustainably produced, naturally raised or pasture-raised animal products that are commonly produced on diversified farms. The specific objectives of this study were to characterise diversified small-scale farms (DSSF) in California, estimate the prevalence of Salmonella enterica and Campylobacter spp. in livestock and poultry, and evaluate the association between farm- and sample-level risk factors and the prevalence of Campylobacter spp. on DSSF in California using a multilevel logistic model. Most participating farms were organic and raised more than one animal species. Overall Salmonella prevalence was 1.19% (95% confidence interval (CI95) 0.6–2), and overall Campylobacter spp. prevalence was 10.8% (CI95 = 9–12.9). Significant risk factors associated with Campylobacter spp. were farm size (odds ratio (OR)10–50 acres: less than 10 acres = 6, CI95 = 2.11–29.8), ownership of swine (OR = 9.3, CI95 = 3.4–38.8) and season (ORSpring: Coastal summer = 3.5, CI95 = 1.1–10.9; ORWinter: Coastal summer = 3.23, CI95 = 1.4–7.4). As the number of DSSF continues to grow, evaluating risk factors and management practices that are unique to these operations will help identify risk mitigation strategies and develop outreach materials to improve the food safety of animal and vegetable products produced on DSSF.
