Article

Full-text available

Jan 2024

Diabetes is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces. Hyperglycaemia, also called raised blood glucose or raised blood sugar, is a common effect of uncontrolled diabetes and over time leads to serious damage to many of the body's systems, especially the nerves and blood vessels. Diabetic foot disease (DFD) is one of the most debilitating complications of diabetes mellitus. It encompasses infection, ulceration, and osseous destruction of the foot of a person with diabetes. Diabetic foot requires utmost care and the need for efficient and effective management of foot care is paramount. Taking into consideration the importance of adequate foot care in alleviating existing complications and preventing further ones from occurring, this quantitative study was conducted to assess the knowledge and practice of foot care among the diabetic patients in a selected Hospital of Thrissur district. The main objectives of the study were to assess the knowledge and practice of foot care among the patients, to associate the levels of knowledge of foot care among them with their selected demographic variables, to correlate the knowledge and practice among diabetic patients regarding foot care, and to prepare and distribute an information booklet on foot care. Through purposive sampling technique, 60 participants who fulfilled the inclusion and exclusion criteria were selected as samples. The data was collected using a questionnaire. The setting of the study was conducted in Aswini hospital limited, Thrissur. The data collected was analysed by quantitative and inferential statistics. The study was revealed that 7(11.66%) had inadequate knowledge and 53 (88.33%) had adequate knowledge. Regarding the level of practice of foot care among diabetic patients 50(83.33%) maintained good practice and 10 (16.66%) samples reported poor practice. Analysis showed that there was no significant association between demographic variables and knowledge. However an association between knowledge and practice has been observed. The present study reveals the correlation between level of knowledge and practice of foot care among diabetic patients The relationship between level of knowledge and practice on foot care are tested by Karl Pearsons's Correlation. The calculated Karl Pearson's Correlation coefficient value is +1, which is statistically significant at 0.05 level. Hence there was a perfect positive correlation found between knowledge and practice. Thus the research hypothesis was accepted and null hypothesis was rejected.

A Critical Care Societies Collaborative Statement: Burnout Syndrome in Critical Care Health-care Professionals. A Call for Action

Article

Full-text available

Jul 2016
AM J RESP CRIT CARE

Burnout syndrome (BOS) occurs in all types of health-care professionals and is especially common in individuals who care for critically ill patients. The development of BOS is related to an imbalance of personal characteristics of the employee and work-related issues or other organizational factors. BOS is associated with many deleterious consequences, including increased rates of job turnover, reduced patient satisfaction, and decreased quality of care. BOS also directly affects the mental health and physical well-being of the many critical care physicians, nurses, and other health-care professionals who practice worldwide. Until recently, BOS and other psychological disorders in critical care health-care professionals remained relatively unrecognized. To raise awareness of BOS, the Critical Care Societies Collaborative (CCSC) developed this call to action. The present article reviews the diagnostic criteria, prevalence, causative factors, and consequences of BOS. It also discusses potential interventions that may be used to prevent and treat BOS. Finally, we urge multiple stakeholders to help mitigate the development of BOS in critical care health-care professionals and diminish the harmful consequences of BOS, both for critical care health-care professionals and for patients.

The Impact of Nursing Education on Ventilator-Associated Pneumonia Prevention Bundle to Reduce Incidence of Infection: A Quality Improvement Project

Article

Jan 2024
Dimens Crit Care Nurs

Background: Ventilator-associated pneumonia (VAP) is a health care-acquired infection that leads to poor patient outcomes, increased length of hospital stay, exhaustion of health care resources, and unnecessary increases in health care costs. Objectives: This project was designed to educate registered nurses on the importance of an evidence-based VAP prevention bundle that reduces the overall incidence of VAP infections. Methods: Patients (N = 146) were enrolled in this quasi-experimental project that took place in a 14-bed neuro trauma surgical burn intensive care unit (ICU) at a level 1 trauma center. Data were collected from the chart review of patients admitted to the neuro trauma surgical burn ICU prior to and after nursing education intervention. The difference in VAP rate and enhanced nursing knowledge were the primary outcome measures. Results: Data suggest improvement in several patient outcomes. Ventilator days were shortened from 17.45 days to 13.42 days (P = .085), and ICU length of stay decreased from 24.77 days to 17.62 days (P = .035). Patient laboratory data show improved white blood cell values (P < .001), less oxygen requirements (P < .001), and fewer patients meeting the diagnostic criteria for VAP (P = .073). Discussion: Results suggest there were no statistically significant changes in the knowledge of registered nurses or oral care bundle compliance; however, improvements in patient data following the provider education suggest that continued education to nursing staff will have a positive impact on reducing hospital stay and significant costs associated with a VAP infection.

Nurses quality of life, sleep disturbance, and intention to leave critical care units: A cross-sectional moderated mediation analysis

Article

Dec 2023
Intensive Crit Care Nurs

Objectives: This study aims to explore the complex relationships between personal and demographic factors, intermediary factors such as quality of life (depression, anxiety, stress, burnout), and the mediating impact of sleep disturbance on nurses' intention to leave critical care units. Design: Cross-sectional quantitative survey. Setting: Data were collected from registered nurses at a major university hospital in southern Italy. Seven inpatient critical care units were sampled. Main outcome measures: Intention to leave critical care units. Results: We included 160 participants recruited over five weeks in May and June 2023. The data showed that most were female, married, and possessed a bachelor's degree in nursing. The mean quality of life score was moderate, while stress, anxiety, and burnout were mild. A significant percentage of nurses reported poor sleep quality. Logistic regression indicates that service length did not significantly impact the intention to leave. The structural equation model showed that stress positively correlated with emotional exhaustion, whereas job quality was negatively associated with emotional exhaustion and the intention to leave. Sleep disturbance did not explain the relationship between stress and emotional fatigue; however, the results revealed that male gender moderated sleep mediation. Conclusions: This study investigated factors influencing intention to leave among critical care unit nurses. The results suggest that the role of sleep disturbance should always be considered when assessing the issue. In this chain of causes, sleep disturbance explains the relationship between stress and emotional exhaustion. Furthermore , the strength of this mediation was influenced by gender, particularly by the male gender. Implications for Clinical Practice: Stress and emotional exhaustion significantly impact nurses' working quality of life, particularly when sleep quality is taken into account. This leads to a higher intention to leave critical care units. To reduce this tendency, healthcare managers could implement specific evidence-based interventions to promote a good climate of work, which would positively affect stress, emotional exhaustion and sleep disturbance. The likelihood of intention to leave decreased with achieving personal self-fulfilment among nurses.

Patient Safety and Patient Safety Culture: Foundations of Excellent Health Care Delivery

Article

Sep 2014
Nephrol Nurs J

In 1999, patient safety moved to the forefront of health care based upon astonishing statistics and a landmark report released by the Institute of Medicine (IOM). This report, To Err is Human: Building a Safer Health System, caught the attention of the media, and there were headlines across the nation about the safety (or lack of safety) for patients in healthcare organizations. In the ensuing years, there have been many efforts to reduce medical errors. Clinicians reviewed their practices, researchers looked for better ways of doing things, and safety and quality organizations focused attention on the topic of patient safety. Initiatives and guidelines were established to define, measure, and improve patient safety practices and culture. Nurses remain central to providing an environment and culture of safety, and as a result, nurses are emerging as safety leaders in the healthcare setting. This article discusses the history of the patient safety movement in the United States and describes the concepts of patient safety and patient safety culture as the foundations for excellent health care delivery.

Variation in Critical Care Services across North America and Western Europe

Article

Oct 2008
CRIT CARE MED

Objective: Critical care represents a large percentage of healthcare spending in developed countries. Yet, little is known regarding international variation in critical care services. We sought to understand differences in critical care delivery by comparing data on the distribution of services in eight countries. Design: Retrospective review of existing national administrative data. We identified sources of data in each country to provide information on acute care hospitals and beds, intensive care units and beds, intensive care admissions, and definitions of intensive care beds. Data were all referenced and from as close to 2005 as possible. Setting: United States, France, United Kingdom, Canada, Belgium, Germany, The Netherlands, and Spain. Patients: Not available. Interventions: None. Measurements and Main Results: No standard definition existed for acute care hospital or intensive care unit beds across countries. Hospital beds varied three-fold from 221/100,000 population in the United States to 593/100,000 in Germany. Adult intensive care unit beds also ranged seven-fold from 3.3/100,000 population in the United Kingdom to 24.0/100,000 in Germany. Volume of intensive care unit admissions per year varied ten-fold from 216/100,000 population in the United Kingdom to 2353/100,000 in Germany. The ratio of intensive care unit beds to hospital beds was highly correlated across all countries except the United States (r = .90). There was minimal correlation between the number of intensive care unit beds per capita and health care spending per capita (r = .45), but high inverse correlation between intensive care unit beds and hospital mortality for intensive care unit patients across countries (r = −.82). Conclusions: Absolute critical care services vary dramatically between countries with wide differences in both numbers of beds and volume of admissions. The number of intensive care unit beds per capita is not strongly correlated with overall health expenditure, but does correlate strongly with mortality. These findings demonstrate the need for critical care data from all countries, as they are essential for interpretation of studies, and policy decisions regarding critical care services.

Feb 2007

Simulation is a complex social endeavor, in which human beings interact with each other, a simulator, and other technical devices. The goal-oriented use for education, training, and research depends on an improved conceptual clarity about simulation realism and related terms. The article introduces concepts into medical simulation that help to clarify potential problems during simulation and foster its goal-oriented use. The three modes of thinking about reality by Uwe Laucken help in differentiating different aspects of simulation realism (physical, semantical, phenomenal). Erving Goffman's concepts of primary frames and modulations allow for analyzing relationships between clinical cases and simulation scenarios. The as-if concept by Hans Vaihinger further qualifies the differences between both clinical and simulators settings and what is important when helping participants engage in simulation. These concepts help to take the social character of simulation into account when designing and conducting scenarios. The concepts allow for improved matching of simulation realism with desired outcomes. It is not uniformly the case that more (physical) realism means better attainment of educational goals. Although the article concentrates on mannequin-based simulations that try to recreate clinical cases to address issues of crisis resource management, the concepts also apply or can be adapted to other forms of immersive or simulation techniques.
