Health Based Geographic Information Systems (GIS) and their Applications.

Medical researches as well as the study of the Earth’s surface, better still, geography are interlinked with each other; their relationship dates from antiquity. The science of Geographic Information Systems and, by extension, Geomatics engineering belongs to a discipline which is constantly developing at a global level. This sector has many applications regarding medical / epidemiological research and generally, the social sciences. Furthermore, this discipline may act as a decision making tool in the healthcare sector and it might contribute to the formulation of policies into the healthcare sector. The use of GIS so as to solve public health issues has an exponential increase and has been vital to the understanding and treatment of health problems in different geographic areas. In recent years, the use of various information technology services and software has lead health professionals to work more effectively.

A literature review on stress and coping strategies in nursing students

Abstract Background: While stress is gaining attention as an important subject of research in nursing literature, coping strategies, as an important construct, has never been comprehensively reviewed. Aim: The aims of this review were: (1) to identify the level of stress, its sources, and (2) to explore coping methods used by student nurses during nursing education. Methods: This is a systematic review of studies conducted from 2000 to 2015 on stress and coping strategies in nursing students. CINAHL, MEDLINE, PsycINFO and PubMed were the primary databases for the search of literature. Keywords including “stress”, “coping strategy”, “nursing students” and “clinical practice” in 13 studies met the criteria. Findings: Stress levels in nursing students range from moderate to high. Main stressors identified included stress through the caring of patients, assignments and workloads, and negative interactions with staff and faculty. Common coping strategies utilized by nursing students included problem-solving strategies such as developing objectives to resolve problems, adopting various strategies to solve problems, and finding the meaning of stressful events. Conclusion: Nurse educators may consider the use of formulation and implementation of empirically tested interventions to reduce stress while enhancing coping skills.

Motivation, leadership, empowerment and confidence: their relation with nurses' burnout.

Introduction: Burnout is usually defined as a state of physical, emotional and mental exhaustion that results from long-term involvement in work situations that are emotionally demanding. A great deal of researches has been devoted to the understanding of factors contributing to burnout and the negative effects that burnout has in the cost and the quality of the provided healthcare. Discussion: Many researchers believe that in difficult and stressful working conditions the work environment should be changed in order to reduce burnout levels successfully. Indeed, recent studies have highlighted the role of human resources management in burnout. It has been widely recognized that human resource management policies should be at the core of any sustainable solution that aims to increase health care systems performance and efficient. Conclusion: Motivation, leadership, empowerment and confidence are very important factors that should be considered in this direction because they are strongly related with burnout levels.

General Satisfaction Among Healthcare Workers: Differences Between Employees in Medical and Mental Health Sector.

Background: General satisfaction is a personal experience and sources of satisfaction or dissatisfaction vary between professional groups. General satisfaction is usually related with work settings, work performance and mental health status. Aim: The purpose of this research study was to investigate the level of general satisfaction of health care workers and to examine whether there were any differences among employees of medical and mental health sector. Methods: The sample consisted of employees from the medical and mental health sector, who were all randomly selected. A two-part questionnaire was used to collect data. The first section involved demographic information and the second part was a General Satisfaction Questionnaire (GSQ). The statistical analysis of data was performed using the software package 19.0 for Windows. Descriptive statistics were initially generated for sample characteristics. All data exhibited normal distributions and thus the parametric t-test was used to compare mean scores between the two health sectors. P values < 0.05 were defined as reflecting the acceptable level of statistical significance. Results: 457 healthcare workers completed the questionnaire. The mean age of the sample was 41.8 ± 7.9 years. The Cronbach alpha coefficient for GSQ was 0.79. The total mean score of general satisfaction for the employees in medical sector was 4.5 (5=very satisfied) and for the employees in mental health sector is 4.8. T-test showed that these results are statistical different (t=4.55, p<0.01) and therefore the two groups of healthcare workers feel different general satisfaction. Conclusions: Mental health employees appear to experience higher levels of general satisfaction and mainly they experience higher satisfaction from family roles, life and sexual life, emotional state and relations with patients.

Conflicts management in public sector nursing

ABSTRACT We investigated the sources of conflicts in nursing and individual as well as nurse management strategies for conflict resolution, according to certain demographic and work-related characteristics. A cross-sectional study was conducted using a five-part questionnaire, which was administered to 100 nurses. The majority of nurses reported conflict with other professions, usually physicians, and this type of conflict was mostly reported by the more experienced and in managerial positions nurses. The most common style for conflict management was avoidance, followed by collaboration and also in significantly smaller percentages compromise, competition, mediation and accommodation. Age, work experience, education and managerial position significantly affected the strategy of choice for conflict resolution, with younger nurses, with less responsibilities and no previous conflict management education choosing avoidance as their primary strategy. Collaboration was a strategy chosen by the more educated nurses and the supervisor was the most appropriate person for conflict management. The majority of the nurses reported that the management style of choice was problem solving, indicating a more appropriate and integrated management style that often relates to better job satisfaction and work relations. The most effective way in conflict management is improving our understanding and clarifying the parameters that structure the situation in hand.

Background: According to World Health Organization (WHO), spirituality is an important domain of quality of life especially in terminal, life threatens chronic diseases. For many people spirituality and religion are not just very important dimensions of their existence, but also a source of support that contributes to wellbeing and coping with everyday difficulties of life. Aim: Aim of the study was the translation of the Facit Spiritual Well Being Scale (Facit-Sp12) in Greek language and the validation of the scale for the Greek population. Material and Methods: The Facit-Sp12 questionnaire is an anonymous self-administered questionnaire that contains twelve, four point Likert scale, closed questions (0=Not at all, 1=A little bit, 2=Some-what, 3=Quite a bit, 4=Very Much). The questionnaire was translated into Greek language and then back translated in the English in order to be checked for any inconsistencies. The sample of the study was 183 chronic kidney disease patients, undergoing hemodialysis. Exploratory factor analysis, with principal components analysis with Varimax rotation was performed for checking the construct validity of the questionnaire. The test–retest reliability and the internal consistency were also examined. Statistical analysis performed by the use of SPSS 21.0. Statistical significance level was set at p=0.05 Results: The final Greek version of the questionnaire includes all of the twelve questions. The mean age of the participants was 61.81±13.9. Three factors were exported from the statistical analysis. The Cronbach-α coefficient was 0.77 for the total questionnaire and for each subscale was 0.70 for “meaning”, 0.73 for “peace” and 0.87 for “faith”. Between the three subscales “meaning” had the highest score (mean 12.49, SD=2.865). Conclusions: The Facit Spiritual Wellbeing Scale–Facit-Sp12, is a valuable and reliable questionnaire of three dimensions that can be used for assessing spirituality and spiritual wellbeing in Greek population.

Predicting Factors of Depression and Anxiety in Mental Health Nurses: A Quantitative Cross-Sectional Study

Introduction The nursing profession is characterized as one of the most stressful and emotional dementing professions. It is widely agreed that many nurses are experiencing anxiety and depression as a results of their profession. Purpose The purpose of this study was to assess the prevalence and associated factors of depression and anxiety among mental health nurses working in public psychiatric hospitals, in order to identify independent predictors of mental health disorders risk. Material and Methods A descriptive, cross-sectional study was conducted in which 110 mental health nurses who were working in public psychiatric hospitals of Greece participated. The Patient Health Questionnaire-2 (PHQ-2) and the Generalized Anxiety Disorder-2 (GAD-2) questionnaire along with a sheet with basics demographic, social, and work characteristics, including gender, age, marital status, educational level, working experience in nursing, working position and shift, were used as instrument for data collection. Results The mean age of the nurses was 42.64 years (SD = 5.87 years) and working experience in nursing 15.73 years (SD = 5.64 years). Most participants were women 64.5%, married 59.1% and nursing assistant 53.6%, while 48.2% of them held a higher education degree. A very large percentage found to be classified as depressed (52.7%) and anxious (48.2%) and factors that found to be associated were age, marital status and educational level (for depression and anxiety) and working experience (only for depression). Conclusions Mental health nurses are in high risk for developing psychiatric disorders such as depression and anxiety. Being single, divorced or widowed, older, with many years of experience and a higher education degree can be predicting factors associated with depression and anxiety in mental health nurses.

Stress and coping strategies among nursing students: an international study

Abstract Background: Mounting literature on stress and coping in nursing students are available; however, most of the findings are confined to a single cultural group. Aims: This study was conducted to determine the level of stress, its sources and coping strategies among nursing students from three countries: Greece, the Philippines and Nigeria. Methods: Using a descriptive, comparative research design, 547 nursing students (161 Greek nursing students, 153 Filipino nursing students, 233 Nigerian nursing students) participated in the study from August 2015 to April 2016. Two standardized instruments were used, the Perceived Stress Scale (PSS) and the Coping Behavior Inventory (CBI). Results: Findings revealed that the degree of stress and the type of stressors and coping styles utilized by nursing students differ according to the country of origin. The year of study predicted overall stress (β = –0.149, p < 0.001) while advanced age predicted overall coping (β = 0.008, p = 0.037) in the nursing students. Conclusions: Strengthening nursing students’ positive coping skills may be helpful for them to effectively deal with various stressors during their educational experiences while maximizing learning. Implementing empirically tested approaches maybe useful to prevent the recurrence of stress and lessen its impact such as stress management counseling, counseling programs, establishing peer and family support systems, and formulating hospital policies that will support nursing students.

Pressure Ulcers: Developing Clinical Indicators in Evidence-based Practice. A Prospective Study -

Aims and objectives: It is widely recognized that Intensive Care Unit (ICU) patients have a greater likelihood of developing pressure ulcers in comparison to hospital or home care patients. Accordingly, this study aimed to evaluate whether specific clinical characteristics could be used as clinical indicators towards pressure ulcers prevention. Method: We monitored 210 hospitalized ICU patients during a 12-month period. Pressure ulcers were assessed following the current guidelines. Clinical characteristics such as gender, age, hospitalized days, hemodialysis treatment, hematocrit, and serum albumin levels were considered as the most common predictors for pressure ulcers development. The significance of associations was controlled using multiple logistic regression after adjusting for clinical characteristics and was presented as adjusted odds ratio (AOR). Results: The prevalence of pressure ulcers was 24.3%. Logistic regression revealed that patients with increased age AOR=1.04; (CI: 1.01-1.07) and last-long hospitalization AOR=1.17; (CI: 1.11-1.23) were significantly more likely to present pressure ulcers compared to the younger ones and patients with less length of stay, respectively. We also found that patients under hemodialysis treatment were more likely to present pressure ulcers AOR=4.09; (CI: 1.12-14.98) compared to patients that did not underwent hemodialysis and the risk of pressure ulcers development was decreased by 9% for every single unit of hematocrit value increase AOR=0.91; (CI: 0.82-0.99). Conclusion: Our data analysis confirms that the clinical characteristics that were studied are independently associated with pressure ulcers development, and therefore, it is a crucial incentive to consider that these specific clinical characteristics are important indicators in the evidence-based practice.

Assessment of the relation between religiosity, mental health, and psychological resilience in breast cancer patients

Aim of the study The aim of this study was to examine the relationship between religiosity, mental health, and psychological resilience in breast cancer patients. Material and methods A cross-sectional study was conducted in an oncology department of a hospital in northern Greece during February and March 2017. The sample consisted of 152 breast cancer patients. Data were collected with the following instruments: Patient Health Questionnaire two-item scale, Generalised Anxiety Disorder two-item scale, Connor-Davidson Resilience Scale 25, and Centrality of Religiosity Scale. Also, patients’ characteristics were included, specifically demographic, social, and clinical information. Statistical analyses were conducted with the Statistical Package for the Social Sciences V25. Results According to our results, approximately 1 out of 3 patients had depression and anxiety. Also, the sample had moderate resilience and were moderately religious. Patients who were classified as end-stage cancer patients and those who underwent mastectomy found to be more religious. Religiosity correlated positively with the resilience, while no correlation was found with depression, anxiety, and symptom burden. Based on regression results, religious beliefs seem to be a predictive factor for resilience and resilience is a predictive factor for depression. Conclusions Our findings show that there was no association between religiosity and mental health, while a strong relation was highlighted between religious beliefs and psychological resilience. This study should constitute a starting point for further assessments regarding the fact that religiosity can provide social support that facilitates psychological adaption to illness and helps cancer patients to cope with their illness, which should be recognised by health care professionals.
