Food Hygiene and Safety Practices amongst Food Vendors in the Western Area, Sierra Leone

Food safety and hygiene practices require a multisectoral approach including food, water, sanitation, waste management, transport, education, trade, policies and programs that enable safe food preparation, storage and service. Unsafe food can cause illness keeping people from achieving their full potential and death. This was a descriptive study that uses a mixed method approach to derive insights into the characteristics of food vendors related to demography, knowledge, practices, infrastructure, compliance and recommendation for a policymaking framework. Using the Lemeshows’ sample size formula, 473 vendors from formal (restaurants) and informal (cookri-baffa/table top) sites were interviewed and observed. We found from discussions that respondents had a good understanding on how to keep food safe. However, observed practices were poor 93% handled food with their bare hands, 83% did not cover their hair, and 76% did not wear an apron whilst handling, preparing or serving food, 61% did not keep their finger nails clean or short and 57% did not wash their hand before preparing or serving food. Over half (51%) had access to a toilet but 32% reported their use required payment and emphasized their poor condition/inadequate management. Nearly half (47%) of the vending sites did not have a handwashing facility, with soap and water available. Only 7% reported having any authority oversight of food safety. Food safety and hygiene practices in most cookri shops and restaurants was ‘poor’ with very limited surveillance system in place by competent authorities for compliance of food operators. Hand washing, clean surroundings, and covered food were the most common and emphasized practices to mitigate the risks associated with unsafe food.

Health care staffs’ perception of patient safety culture in hospital settings and factors of importance for this

Many hospital patients are affected by adverse events. Managers are important when improving safety. The perception of patient safety culture varies among health care staff. Health care staff (n = 1023) working in medical, surgical or mixed medical-surgical health care divisions answered the 51 items (14 dimensions) Swedish Hospital Survey on Patient Safety Culture (S-HSOPSC). Respondents with a managerial function scored higher than non-managers for 11 of 14 dimensions, indicating patient safety culture strengths for a majority of dimensions. Enrolled nurses and staff with experience > 10 years also scored high for several dimensions. The 12 dimensions and sample characteristics explained 49% and 26% of the variance for the outcome dimensions Overall Perceptions of Safety and Frequency of Incident Reporting, respectively. RNs, ENs and physicians have different views on patient safety culture. Hospital Management Support and Organisational Learning is some important factors influencing patient safety culture. Bridging the gap in health care staff’s perceptions of safety in order to improve patient safety is of utmost importance. Managers have the responsibility to foster patient safety culture at their workplace and can thus benefit from results when improving safety for patients.

Medication Side Effect Profiles in PD Patients in a Safety-Net Hospital

Background: Compulsive behavior, dyskinesias, motor fluctuations, and hallucinations are common Parkinson’s disease (PD) medication side effects. These are yet to be examined in relation to race and level of education. The goal of this analysis was to identify socioeconomic or clinical variables that are associated with compulsive behavior, dyskinesias, motor fluctuations, and hallucinations in patients in a safety-net hospital. Methods: A movement disorder patient database containing 452 patients with idiopathic PD was analyzed for differences in PD medication side effects using univariate and multivariate logistic regression analysis. Race, sex, and level of education were evaluated as possible confounders. Results: A greater proportion of the patients in this study were Caucasian males. The only variable associated with compulsive behavior was age, with higher age having a protective effect (p = 0.0336). Disease duration (defined as time since the onset of symptoms), diagnosis duration (time since formal diagnosis), and level of education were significantly associated with dyskinesia inunivariate analysis (p =< 0.0001, <0.0001, 0.1236 respectively). However, diagnosis duration was the only variable significantly associated with dyskinesia in multivariate analysis (p = 0.0038), in addition to a borderline significant association when comparing individuals with graduate degree to those who had completed high school education or less (p = 0.0599), with a protective effect of higher education. Disease duration, diagnosis duration, and use of monoamineoxidase inhibitors were also significantly associated with motor fluctuations in the univariate analysis, while only diagnosis duration was significantly associated with motor fluctuations in multivariate analysis (p = 0.0035) with longer diagnosis duration associated with higher risk of motor fluctuations. Age, disease duration, and diagnosis duration were associated with an increased risk of hallucinations in univariate analysis (p =< 0.0001, <0.0001, <0.0001 respectively), but age and disease duration were the only variables associated with hallucinations in multivariate analysis (p = 0.0009, 0.1196 respectively). Race was not associated with a higher risk of compulsive behavior, dyskinesias, motor fluctuations, or hallucinations. Conclusion: Compulsive behavior, dyskinesias, motor fluctuations, and hallucinations in our PD population may be associated with differences in socioeconomic status and access to care, but not with differences in race.

Knowledge Representation in Patient Safety Reporting: An Ontological Approach

Purpose： The current development of patient safety reporting systems is criticized for loss of information and low data quality due to the lack of a uniformed domain knowledge base and text processing functionality. To improve patient safety reporting, the present paper suggests an ontological representation of patient safety knowledge. Design/methodology/approach： We propose a framework for constructing an ontological knowledge base of patient safety. The present paper describes our design, implementation,and evaluation of the ontology at its initial stage. Findings： We describe the design and initial outcomes of the ontology implementation. The evaluation results demonstrate the clinical validity of the ontology by a self-developed survey measurement. Research limitations： The proposed ontology was developed and evaluated using a small number of information sources. Presently, US data are used, but they are not essential for the ultimate structure of the ontology.Practical implications： The goal of improving patient safety can be aided through investigating patient safety reports and providing actionable knowledge to clinical practitioners.As such, constructing a domain specific ontology for patient safety reports serves as a cornerstone in information collection and text mining methods.Originality/value： The use of ontologies provides abstracted representation of semantic information and enables a wealth of applications in a reporting system. Therefore, constructing such a knowledge base is recognized as a high priority in health care.

Construction and Application of Knowledge Graph for Quality and Safety Supervision of Transportation Engineering

Knowledge graph technology play a more and more important role in various fields of industry and academia.This paper firstly introduces the general framework of the knowledge graph construction,which includes three stages:information extraction,knowledge fusion and knowledge processing.In order to improve the efficiency of quality and safety supervision of transportation engineering construction,this paper constructs a knowledge graph by acquiring multi-sources heterogeneous data from supervision of transportation engineering quality and safety.It employs a bottom-up construction strategy and some natural language processing methods to solve the problems of the knowledge extraction for transportation engineering construction.We use the entity relation extraction method to extract the entity triples from the multi-sources heterogeneous data,and then employ knowledge inference to complete the edges in the constructed knowledge graph,finally perform quality evaluation to add the valid triples to the knowledge graph for updating.Subgraph matching technology is also exploited to retrieve the constructed knowledge graph for efficiently acquiring the useful knowledge about the quality and safety of transportation engineering projects.The results show that the constructed knowledge graph provides a practical and valuable tool for the quality and safety supervision of transportation engineering construction.

Agricultural GMO safety administration in China

Given the public concern over the safety of genetically modified （GM） technology and products, the article elaborated the safety regulatory and administration on agricultural GMOs in China. China has made a set of laws and regulations of GMO safety management and confirmed competent authorities with clear-cut responsibilities. According to the laws and regulations, GMO products before entering markets have to pass through safety evaluation, get production and processing permission and be labeled correctly. For the importation of GM products, China has set up an import approval system. In addition, China has established technical supportive systems, including safety evaluation specifications, trial specifications and criteria specifications. The existing regulatory system supervises and regulates all activities and work related to agri- cultural GMOs in China.

Design methodology for the safety of underground rock engineering

In order to optimise the safety of underground rock engineering construction and the long-term security of the resultant facilities, it is necessary to have a knowledge of the likely hazards. These risks or hazards fall into the four categories of 'known beforehand and relatively easily addressed', 'known beforehand and not easily addressed', 'not known beforehand and relatively easily addressed', and 'not known beforehand and not easily addressed'. This paper describes how these four types of hazard can be incorporated into a design methodology approach, including the process by which the relevant mechanical rock mass parameters can be recognised for modelling and hence predictive purposes. In particular, there is emphasis on the fact that information and judgement are the keys to safety——whether the hazards are known or unknown before construction proceeds.

A Comparative Assessment of Patient Safety Culture between Iranian Selected Hospitals and Agency for Healthcare Research and Quality (AHRQ) Report

Establishing a culture of patient safety can be effective in reducing the incidence of medical errors and solving concerns of safety inadequacy in health systems. The purpose of this study was to assess the culture of patient safety in the selected hospitals, and compare the results with published reports of AHRQ. This study was approved by the Ethical Committee of BPUMS. The subjects signed the informed consent form to participle in the study. Confidentiality was maintained throughout the study reports. Cross-sectional study was conducted in 2012;the study sample was composed of 364 staffs working at two selected hospitals affiliated to Bushehr University of Medical Sciences. Hospital Survey on Patient Safety Culture was used to collect data. Descriptive statistical analysis was used to analyze the data. No reports of events in both studied hospitals and benchmark were accounted for the most of the reported errors, although this indicator in studied hospitals was nearly 23% higher than that of the benchmark report. The highest patient safety grade in studied hospitals and benchmark was “acceptable” and “very good”, respectively. The highest percentage of positive response to patient safety dimension was organization learning and then teamwork within units in studied hospitals. Teamwork within units also was the highest average percent in benchmark report. Non-punitive response to errors had the lowest positive percentage of participant responses in both studies. To achieve the patient safety culture, we do not need to blame individual and apply punitive approach when errors occur. This makes person accept responsibility for their actions honestly and report errors in a timely manner to prevent reoccurrence of similar errors.
