Risk assessment for postoperative outcomes in a mixed hospitalized gynecological population by the Dutch safety management system (Veiligheidsmanagementsysteem, VMS) screening tool 'frail elderly'.

PURPOSE: Frailty is associated with a higher risk for negative postoperative outcomes. This study aimed to determine the association between the screening tool of the Dutch safety management system, Veiligheidsmanagementsysteem (VMS) 'frail elderly' and postoperative complications in a gynecological population. METHODS: This cohort study included women aged 70 years or older, who were scheduled for any kind of gynecological surgery. VMS screening data (including risk for delirium, falling, malnutrition, and functional impairment) were extracted from the electronic patient records. VMS score could range between 0 and 4 patients with a VMS score of one or more were considered frail. Data on possible confounding factors and complications within 30 days after surgery, classified with the Clavien-Dindo classification, were collected. Regression analysis was performed. RESULTS: 157 women were included with a median age of 74 years (inter quartile range 71-79). Most patients underwent prolapse surgery (52%) or hysterectomy (31%). Forty-one patients (26%) experienced any postoperative complication. Sixty-two patients (39%) were considered frail preoperatively by the VMS screening tool. Frailty measured with the VMS screening tool was not independently associated with postoperative complications in multivariable analysis (Odds ratio 1.18; 95% CI 0.49-2.82). However, a recent fall in the last 6 months (n = 208) was associated with postoperative complications (Odds ratio 3.90; 95% CI 1.57-9.66). CONCLUSION: An independent association between frailty, determined by the VMS screening tool 'Frail elderly', and postoperative complications in gynecological surgery patients could not be confirmed. A recent fall in the last 6 months seems associated with postoperative complications.

Risk assessment of workers' exposure to BTEX and hazardous area classification at gasoline stations.

Vaporization of benzene, toluene, ethylbenzene, and xylene (BTEX) compounds pollutes the air and causes health hazards at gasoline stations. This study revealed the risk of BTEX exposure according to the hazardous area classification at gasoline stations. The risk assessment of gasoline workers from a representative group of 47 stations, which followed the United States Environmental Protection Agency-IRIS method of assessing BTEX exposure, was expressed as the hazard index (HI). A result of matrix multipliers of the hazardous exposure index and fire possibility from flammable gas classified hazardous area-I and area-II at the fuel dispensers. BTEX concentrations were actively sampled in ambient air and a flammable gas detector was used to measure the flammability level. Results showed that the BTEX concentrations from ambient air monitoring were in the range of 0.1-136.9, 8.1-406.0, 0.8-24.1 and 0.4-105.5 ppb for benzene, toluene, ethylbenzene, and xylene, respectively, which exceeded the NIOSH exposure limit of 100 ppb of benzene concentration. The risk assessment indicated that five stations reached an unacceptable risk of worker exposure to BTEX (HI>1), which correlated with the numbers of gasoline dispensers and daily gasoline sold. The risk matrix classified hazardous area-I at 4 meters and hazardous area-II at 4-8 meters in radius around the fuel dispensers. This study revealed the hazardous areas at gasoline stations and suggests that entrepreneurs must strictly control the safety operation practice of workers, install vapor recovery systems on dispenser nozzles to control BTEX vaporization and keep the hazardous areas clear of fire ignition sources within an eight-meter radius of the dispensers.

Patient safety culture and associated factors among health care professionals at public hospitals in Dessie town, north east Ethiopia, 2019.

INTRODUCTION: Patient safety culture is defined as the attitudes, perceptions, and values that staffs share within an organization related to patient safety. The safety of health care is now a major global concern. It is likely that millions of people suffer disabling injuries or death directly related to medical care. Particularly in developing and transitional countries, patient harm is a global public health problem. The objective of the study is to assess patient safety culture and associated factors among health care professionals working in public hospitals in Dessie town, North East Ethiopia, 2019. METHODS: Facility based quantitative study was employed from March 15 -April 30, 2019 in public hospitals in Dessie town. Four hundred and twenty two health care professionals were recruited to complete a structured pretested self-administered questionnaire. The data was cleaned, coded and entered in to Epi Info-7 and exported to SPSS version 20. Data was further analyzed using bivariate and multivariate logistic regression analyses. Variables with P value of less than 0.05 in multivariate analysis were declared as statistically significant at 95% CI. RESULTS: Of the 422 recruited a total of 411 participants completed the survey with a response rate of 97.4%. Close to half (184(44.8%)) of the participants indicated good patient safety culture. Good patient safety culture was positively associated with working in primary hospital (AOR = 2.56, 95% CI = 1.56, 4.21). On the other hand, good patient safety culture was negatively associated with health professional's age between 25-34 year (AOR = 0.25, 95% CI = 0.08-0.74) and working in Pediatrics ward (AOR = 0.39, 95% CI = 0.17-0.9) and in emergency ward (AOR = O.25, 95%CI = 0.09-0.67). CONCLUSION: The overall level of patient safety culture was under 50%. Good patient safety culture had positive association with working in primary hospital and negative association with professionals' age between 25-29 year, 30-34 year and working in pediatrics and emergency ward. Implementing actions that support all dimensions of safety culture should be promoted at all levels of hospitals.

Incident Reporting System in an Italian University Hospital: A New Tool for Improving Patient Safety.

Clinical risk management constitutes a central element in the healthcare systems in relation to the reverberation that it establishes, and as regards the optimization of clinical outcomes for the patient. The starting point for a right clinical risk management is represented by the identification of non-conforming results. The aim of the study is to carry out a systematic analysis of all data received in the first three years of adoption of a reporting system, revealing the strengths and weaknesses. The results emerged showed an increasing trend in the number of total records. Notably, 86.0% of the records came from the medical category. Moreover, 41.0% of the records reported the possible preventive measures that could have averted the event and in 30% of the reports are hints to be put in place to avoid the repetition of the events. The second experimental phase is categorizing the events reported. Implementing the reporting system, it would guarantee a virtuous cycle of learning, training and reallocation of resources. By sensitizing health workers to a correct use of the incident reporting system, it could become a virtuous error learning system. All this would lead to a reduction in litigation and an implementation of the therapeutic doctor-patient alliance.

Patient safety from executive hospital management to wards: A qualitative study identifying factors influencing implementation.

AIM: To examine the journey of safety initiatives from executive hospital management to ward. BACKGROUND: Hospital management teams are often responsible for identifying safety priorities and ensuring delivery of these. METHOD: Naturalistic study design within a large NHS Hospital Trust. Using semi-structured interviews, focus groups and secondary data analysis, the study examines the implementation of safety initiatives. RESULTS: While hospital management developed five safety initiatives, only one of these (falls prevention) was actually seen to permeate all layers of the organisation. Other initiatives stopped one layer down. Both middle management and ward staff added to the list of initiatives developed, resulting in 16 priorities. A range of positive and negative influences to successful implementation are identified. CONCLUSIONS: Safety initiatives need positive reinforcement at all levels to be addressed appropriately. The research suggests that a model related to improvement science may prove useful in ensuring that priorities are addressed. IMPLICATIONS FOR NURSING MANAGEMENT: Care should be taken to ensure that safety initiatives are successfully implemented at all levels within an organisation. Identifying priorities with staff and sharing values and priorities are a key approach to leading such initiatives.

Constraints of coal mining safety management efficiency.

BACKGROUND: Investigation of the safety management efficiency in a coal mine aims to improve its safety management level thus ensuring coal mining safety. However, the safety management efficiency is affected by many factors especially for those coal mines operated underground. Furthermore, the constraint factors that are difficult to be identified and eliminated may impede safety management efficiency. OBJECTIVE: This work aims to explore the constraints affecting safety management efficiency through a mathematical model accompanied by some effective measures guided by the theory of constraint (TOC). METHODS: An index system for coal mining safety management efficiency (CMSME) is first established. Then a mathematical model roughly identifying the constraint factors is constructed. The principle of the proposed model is a comparison with the changes of the ratio of integrated CMSME and the ratio of each impact factor over a certain period. Thus, a constraint factor may be one whose ratio changes at a slower rate than that of the integrated CMSME. Following this, some measures are adopted to identify one, or more, real constraints. Finally, the constraints may be broken by internal, or external, means. RESULTS: A case study from Quandian coal mine verified the proposed method: the constraints affecting CMSME could be identified and broken through during the production. This research currently is applied to coal mining activities in a few coal mines, and it will be widely used in the future. CONCLUSIONS: This paper provides a novel method investigating the constraints affecting CMSME and breaking through them. The case study shows that breaking through constraints during the production is beneficial to CMSME. Furthermore, a coal mine with a high CMSME index may still, at some time, have one, or more, bottleneck constraints.

A highway crash risk assessment method based on traffic safety state division.

In order to quantitatively analyze the influence of different traffic conditions on highway crash risk, a method of crash risk assessment based on traffic safety state division is proposed in this paper. Firstly, the highway crash data and corresponding traffic data of upstream and downstream are extracted and processed by using the matched case-control method to exclude the influence of other factors on the model. Secondly, considering the weight of traffic volume, speed and occupancy, a multi-parameter fusion cluster method is applied to divide traffic safety state. In addition, the quantitative relationship between different traffic states and highway crash risk is analyzed by using Bayesian conditional logistic regression model. Finally, the results of case study show that different traffic safety conditions are in different crash risk levels. The highway traffic management department can improve the safety risk management level by focusing on the prevention and control of high-risk traffic safety conditions.

Medical injection and access to sterile injection equipment in low- and middle-income countries: a meta-analysis of Demographic and Health Surveys (2010-2017).

BACKGROUND: Unsafe injection practices contribute to increased risks of blood-borne infections, including human immunodeficiency virus, hepatitis B and hepatitis C viruses. The aim of this study was to estimate the prevalence of medical injections as well as assess the level of access to sterile injection equipment by demographic factors in low- and middle-income countries (LMICs). METHODS: We carried out a meta-analysis of nationally representative Demographic and Health Surveys (DHSs) conducted between 2010 and 2017 in 39 LMICs. Random effects meta-analysis was used in estimating pooled and disaggregated prevalence. All analyses were conducted using Stata version 14 and Microsoft Excel 2016. RESULTS: The pooled 12-month prevalence estimate of medical injection was 32.4% (95% confidence interval 29.3-35.6). Pakistan, Rwanda and Myanmar had the highest prevalence of medical injection: 59.1%, 56.4% and 53.0%, respectively. Regionally, the prevalence of medical injection ranged from 13.5% in west Asia to 42.7% in south and southeast Asia. The pooled prevalence of access to sterile injection equipment was 96.5%, with Pakistan, Comoros and Afghanistan having comparatively less prevalence: 86.0%, 90.3% and 90.9%, respectively. CONCLUSIONS: Overuse of medical injection and potentially unsafe injection practices remain a considerable challenge in LMICs. To stem the tides of these challenges, national governments of LMICs need to initiate appropriate interventions, including education of stakeholders, and equity in access to quality healthcare services.

Stigma at work: The psychological costs and benefits of the pressure to work safely.

INTRODUCTION: Workplace accidents and injuries can be quite costly to both individual employees and their organizations. While safety climate (i.e., perceptions of policies and procedures related to safety that should reflect an organization's value of safety) has been established as a predictor of safety behaviors, less research has considered the possible negative pressures that could result from an environment that emphasizes safety. Though organizations may intend to create a positive safety climate, concerns about being treated differently if an employee were to be involved in a safety incident may result in unintended, but detrimental safety and health outcomes. METHOD: This study investigated the stigma associated with being involved in a safety-related incident in relation to self-reported safety behaviors and psychological health outcomes. The data were acquired through a two-wave prospective design, surveying workers from Amazon Mechanical Turk (MTurk; N = 528) who indicated they were exposed to at least one physical work stressor (e.g., heavy lifting; air quality; standing for extended periods) a few times each month or more. RESULTS: When controlling for safety climate, safety stigma was related to decreased safety compliance and poorer psychological health. There was a marginally significant interaction between safety stigma and safety motivation in relation to safety compliance. CONCLUSIONS: These findings suggest that experiencing pressure to work safely, for fear of being evaluated negatively, may actually come at the cost of employees' safety compliance and psychological health. Practical applications: These results may be useful in assessing and intervening to improve an organization's safety climate. Organizations should closely examine the climate for safety to ensure that positive aspects of safety are not undermined by a stigmatizing pressure associated with safety in the work environment.

Responding to adverse patient safety events in Viet Nam.

BACKGROUND: The psychological and professional impact of adverse events on doctors and nurses is well-established, but limited data has emerged from low- and middle-income. This article reports the experiences of being involved in a patient safety event, incident reporting and organisational support available to assist health professionals in Viet Nam to learn and recover. METHOD: Doctors and nurses (1000) from all departments of a 1500-bed surgical and trauma hospital in Viet Nam were invited to take part in a cross-sectional survey. The survey explored respondents' involvement in adverse events and/or near miss, their emotional, behavioural and coping responses, experiences of organisational incident reporting, and the learning and/or other consequences of the event. Survey items also assessed the availability of organisational support including peer support and mentorship. RESULTS: Of the 497 respondents, 295 (59%) experienced an adverse event in which a patient was harmed, of which 86 (17%) resulted in serious patient harm. 397 (80%) of respondents experienced a near miss, with 140 of these (28%) having potential for serious harm. 386 (77%) reporting they had been affected professionally or personally in some way, with impacts to psychological health (416; 84%), physical health (388; 78%), job satisfaction (378; 76%) and confidence in their ability (276; 56%) commonly reported. Many respondents were unable to identify local improvements (373; 75%) or organisation-wide improvements following safety events (359; 72%) and 171 (34%) admitted that they had not reported an event to their organisation or manager that they should have. CONCLUSIONS: Health professionals in Viet Nam report impacts to psychological and physical health as a result of involvement in safety events that reflect those of health professionals internationally. Reports of limited organisational learning and improvement following safety events suggest that patient safety culture is underdeveloped in Viet Nam currently. In order to progress work on patient safety cultures and incident reporting in Viet Nam, health professionals will need to be convinced not only that they will not be exposed to punitive action, but that learning and positive changes will occur as a result of reporting safety events.

Durable Improvement in Patient Safety Culture Over 5 Years With Use of High-volume Incident Learning System.

PURPOSE: Incident learning systems (ILSs) require substantial time and effort to maintain, risking staff burnout and ILS disuse. Herein, we assess the durability of ILS-associated safety culture improvements and ILS engagement at 5 years. METHODS AND MATERIALS: A validated survey assessing safety culture was administered to all staff of an academic radiation oncology department before starting ILS and annually thereafter for 5 years. The survey consists of 70 questions assessing key cultural domains, overall patient safety grade, and barriers to incident reporting. A χ2 test was used to compare baseline scores before starting the ILS (pre-ILS) with the aggregate 5 years during which ILS was in use (with ILS). ILS engagement was measured by the self-reported number of ILS entries submitted in the previous 12 months. RESULTS: The survey response rate was ≥68% each year (range, 68%-80%). High-volume event reporting was sustained (4673 reports; average of 0.9 ILS entries per treatment course). ILS engagement increased, with 43% of respondents submitting reports during the 12 months pre-ILS compared with 64% with ILS in use (P < .001). Significant improvements (pre- vs. with-ILS) were observed in the cultural domains of patient safety perceptions (25% vs 39%; P < .03), and responsibility and self-efficacy (43% vs 60%; P < .01). The overall patient safety grade of very good or excellent significantly increased (69% vs 85%; P < .01). Significant reductions were seen in the following barriers to error reporting: embarrassment in front of colleagues, getting colleagues into trouble, and effect on department reputation. CONCLUSIONS: Comprehensive incident learning was sustained over 5 years and is associated with significant durable improvements in metrics of patient safety culture.

Fall Prevention Among Community-Dwelling Older Adults: Current Guidelines and Older Adult Responses.

Older adults are vulnerable to falls that result in injury and disability, making fall prevention a national priority. The purpose of the current study was to evaluate community-dwelling older adults' perceptions about falls and fall prevention activities to guide interventions. Participants had high awareness of falls and believed that they could reduce their risk of falling. Approximately three fourths of participants reported taking actions to reduce risk of falling; however, participation in community fall prevention programs was low. The survey used provides a method to help nurses identify targets for fall prevention interventions to reduce this physical health disparity in vulnerable older populations.

Is there agreement between worker self and supervisor assessment of worker safety performance? An examination in the construction industry.

INTRODUCTION: Individual safety performance (behavior) critically influences safety outcomes in high-risk workplaces. Compared to the study of generic work performance on different measurements, few studies have investigated different measurements of safety performance, typically relying on employees' self-reflection of their safety behavior. This research aims to address this limitation by including worker self-reflection and other (i.e., supervisor) assessment of two worker safety performance dimensions, safety compliance and safety participation. METHOD: A sample of 105 workers and 17 supervisors in 17 groups in the Chinese construction industry participated in this study. Comparisons were made between worker compliance and participation in each measurement, and between workers' and supervisors' assessment of workers' compliance and participation. Multilevel modeling was adopted to test the moderating effects on the worker self-reflection and supervisor-assessment relationship by group safety climate and the work experience of supervisors. RESULTS: Higher levels of safety compliance than participation were found for self-reflection and supervisor assessment. The discrepancy between the two measurements in each safety performance dimension was significant. The work experience of supervisors attenuated the discrepancy between self- and supervisor-assessment of compliance. Contrary to our expectations, the moderating effect of group safety climate was not supported. CONCLUSIONS: The discrepancy between worker self- and supervisor-assessment of worker safety performance, thus, suggests the importance of including alternative measurements of safety performance in addition to self-reflection. Lower levels of participation behavior in both raters suggest more research on the motivators of participatory behavior. Practical applications The discrepancy between different raters can lead to negative reactions of ratees, suggesting that managers should be aware of that difference. Assigning experienced supervisors as raters can be effective at mitigating interrater discrepancy and conflicts in the assessment of compliance behavior.

Novel Methods for Environmental Assessment of Pedestrian Injury: Creation and Validation of the Inventory for Pedestrian Safety Infrastructure.

Nationally, 80% of pedestrian fatalities occur in urban environments, yet the distribution of injuries across urban areas is not uniform. Identifying street-level risk factors for pedestrian injury is essential for urban planning and improvement projects, as well as targeted injury prevention efforts. However, creating and maintaining a comprehensive database of a city's traffic safety infrastructure can be cumbersome and costly. The purpose of this study was to create and validate a neighborhood environmental observational assessment tool to capture evidence-based pedestrian safety infrastructure using Google Street View (GSV)-The Inventory for Pedestrian Safety Infrastructure (IPSI). We collected measures in-person at 172 liquor stores in Baltimore City from June to August 2015 to assess the tool's reliability; we then collected IPSI measures at the same 172 locations using GSV from February to March 2016 to assess IPSI reliability using GSV. The majority of items had good or excellent levels of inter-rater reliability (ICC ≥ 0.8), with intersection features showing the highest agreement across raters. Two scales were also developed using exploratory factor analysis, and both showed strong internal consistency (Cronbach's alpha ≥ 0.6). The IPSI provides a valid, economically efficient tool for assessing pedestrian safety infrastructure that can be employed for a variety of research and urban planning needs. It can also be used for in-person or GSV observation. Reliable and valid measurement of pedestrian safety infrastructure is essential to effectively prevent future pedestrian injuries.

Differences between serious and nonserious patient safety incidents in the largest hospital district in Finland.

OBJECTIVES: To determine if and in what ways serious patient safety incidents differ from nonserious patient safety incidents. METHODS: Statistical analysis was performed on patient safety incident reports that were reported in 2015 in Finland's largest hospital district (Helsinki and Uusimaa, HUS). Reports were divided into two groups: nonserious incidents and serious incidents. Differences between groups were studied from several types of categorically divided information. RESULTS: Of the total number of reports (15,863), 1% were serious incidents (175). Serious and nonserious incidents differed significantly from each other. Serious incidents concerning laboratory, imaging, or medical equipment were more common. On the other hand, incidents concerning medication, infusion, and blood transfusion were less frequent. In serious incidents, the proportion of doctors reporting was greater, and contributing factors were better recognized, the most common being working of procedures. CONCLUSIONS: In the future, special attention should be given to the particular aspects of serious patient safety incidents, such as safe use of medical equipment, training, and handling of procedures. Root cause analysis is an effective way to handle serious incidents and enables the prevention of their reoccurrence. However, a systematic follow-up of the root cause analysis should be developed.

Assessment of safety culture among job positions in high-rise construction: a hybrid fuzzy multi criteria decision-making (FMCDM) approach.

The construction industry is known as one of the most dangerous industries, which not only requires sound operation of executive laws and regulations, but also necessitates the safety culture of all workers at workshops. Therefore, the aim of this research is to identify the factors of safety culture and ranking occupations in jobsites based on those factors in order to proactively improve the safety culture of construction projects and subsequently promote safety conditions and worksites. In this study, safety culture criteria are weighted by a combination of Fuzzy Decision Trail and Evaluation Laboratory and Fuzzy ANP methods. Next, different job positions in high-rise projects are ranked using the Fuzzy Technique for Order of Preference by Similarity to Ideal Solution method. Findings demonstrated that the project manager, site superintendent and supervisor occupations had the highest and labourers had the lowest level of safety culture in the high-rise construction industry. Furthermore, factors such as safety supervision and training must be considered more seriously in order to create a positive safety culture among workers.

Safety Culture and Mortality after Acute Myocardial Infarction: A Study of Medicare Beneficiaries at 171 Hospitals.

OBJECTIVES: To investigate the association between hospital safety culture and 30-day risk-adjusted mortality for Medicare patients with acute myocardial infarction (AMI) in a large, diverse hospital cohort. SUBJECTS: The final analytic cohort consisted of 19,357 Medicare AMI discharges (MedPAR data) linked to 257 AHRQ Hospital Survey on Patient Safety Culture surveys from 171 hospitals between 2008 and 2013. STUDY DESIGN: Observational, cross-sectional study using hierarchical logistic models to estimate the association between hospital safety scores and 30-day risk-adjusted patient mortality. Odds ratios of 30-day, all-cause mortality, adjusting for patient covariates, hospital characteristics (size and teaching status), and several different types of safety culture scores (composite, average, and overall) were determined. PRINCIPAL FINDINGS: No significant association was found between any measure of hospital safety culture and adjusted AMI mortality. CONCLUSIONS: In a large cross-sectional study from a diverse hospital cohort, AHRQ safety culture scores were not associated with AMI mortality. Our study adds to a growing body of investigations that have failed to conclusively demonstrate a safety culture-outcome association in health care, at least with widely used national survey instruments.

Assessment of patient safety culture in private and public hospitals in Peru.

OBJECTIVE: To assess the patient safety culture in Peruvian hospitals from the perspective of healthcare professionals, and to test for differences between the private and public healthcare sectors. Patient safety is defined as the avoidance and prevention of patient injuries or adverse events resulting from the processes of healthcare delivery. DESIGN: A non-random cross-sectional study conducted online. SETTING: An online survey was administered from July to August 2016, in Peru. This study reports results from Lima and Callao, which are the capital and the port region of Peru. PARTICIPANTS: A total of 1679 healthcare professionals completed the survey. Participants were physicians, medical residents and nurses working in healthcare facilities from the private sector and public sector. MAIN OUTCOMES: Assessment of the degree of patient safety and 12 dimensions of patient safety culture in hospital units as perceived by healthcare professionals. RESULTS: Only 18% of healthcare professionals assess the degree of patient safety in their unit of work as excellent or very good. Significant differences are observed between the patient safety grades in the private sector (37%) compared to the public sub-sectors (13-15%). Moreover, in all patient safety culture dimensions, healthcare professionals from the private sector give more favorable responses for patient safety, than those from the public sub-systems. The most significant difference in support comes from patient safety administrators through communication and information about errors. CONCLUSIONS: Overall, the degree of patient safety in Peru is low, with significant gaps that exist between the private and the public sectors.
