Prevalence of Secondary Traumatic Stress Among Psychiatric Nurses in Greece.

The aim of this study was to investigate the prevalence of secondary traumatic stress/compassion fatigue (STS/CF), burnout (BO) and compassion satisfaction (CS) in psychiatric nurses, and their risk factors. The Professional Quality of Life Scale (ProQOL R-IV) and a demographic and work related characteristics questionnaire were distributed to 174 psychiatric nurses in 12 public hospitals in Greece. The majority of participants were at the high risk category for STS/CF (44.8%) and BO (49.4%), while only 8.1% of nurses expressed high potential for CS. Awareness of the factors associated with STS may help nurses to prevent or offset the development of this condition.

QALYs: incorporating the rate of change in quality of life.

The need for comparisons and economic evaluations between various health care interventions requires the evaluation of health-related quality of life. To ensure comparability in terms of the duration of any given condition, measures of quality have to integrate the parameter of time, as is the case in measures like QALY. Usually, the rate of change of quality that results from a given intervention is not incorporated in these measures, resulting in a systematically erroneous estimation of QALYs. This estimation error may lead to either a lower QALYs' value compared to the true one, when quality of life improves with a decreasing rate or deteriorates with an increasing rate, or to a higher QALYs' value compared to the true one, when quality of life improves with an increasing rate or deteriorates with a decreasing rate. The proposed method for the estimation of QALYs takes into account the rate of change in health-related quality of life at all stages and discloses deviations up to 16.67% from currently used methods.

Area of the ROC curve when one point is available.

In this paper, the method of extension is proposed for the calculation of the area under the ROC curve, if only one pair of specificity (Sp0=1-FP0) and sensitivity (Se0) is available. The method of extension is algebraic and is based on the assumption that the ROC curve is continuous, concave, truly ascending and has the form Se=κ0+κ1FP+κ2FP2 in parts. The area under ROC curve is calculated by the formula: AUC=(7Sp0+7Se0-2Sp0Se0)/12.

A randomized double-blind trial of anesthesia provided for colonoscopy by university-degreed anesthesia nurses in Greece: safety and efficacy.

There are numerous studies in the literature of anesthesia administered during colonoscopy including various methods, drugs, and monitoring systems; however, none of them has studied whether a university-degreed nurse anesthesia provider (known as a certified registered nurse anesthetist in the United States) is skillful enough to provide safe anesthesia in patients undergoing endoscopic procedures. The aim of our study was to determine whether anesthesia provided by a university-degreed nurse anesthesia provider during an endoscopic procedure is comparable in terms of safety and efficacy with routine sedation practice. This randomized, double-blind study included 100 adult patients who underwent colonoscopy conducted in the Evgenidion University Hospital during a single year. Subjects were divided into 2 groups: the first group received the usual scheme of intravenous sedation with midazolam and fentanyl administered by a member of the endoscopic team that was blind to Bispectral Index (BIS) values recordings (Group 0). The second group received intravenous bolus injection of propofol bolus by a university-degreed anesthesia registered nurse based on the BIS values (Group 1). The average of the mean BIS values of Group 0 was 85.07 (SD = 8.01) and for Group 1 was 76.1 (SD = 10.88; p = .04). The parameters of "patient memory during procedure" and the satisfaction scores (as self-assessed by the patients as well as 2 gastroenterologists) were also significantly different between the patients of the 2 groups (p = .000). Comparison between the 2 groups showed that the sedation offered by a university-degreed nurse anesthesia provider was absolutely safe and effective, offering particular comfort to the patient during the intervention and contributing significantly to its successful results.

Attitudes toward help-seeking and duration of untreated mental disorders in a sectorized Athens area of Greece.

The purpose of the present study was to investigate the association of opinions towards seeking psychiatric help with the duration of untreated mental disorders in a sectorized Athens area, served by a Community Mental Health Centre. The sample consisted of 134 individuals who had sought help from health or mental health non sectorized services prior to their visit to the Centre (group A) and 156 individuals whose visit to the Center was their first ever contact with a mental health service (group B). Opinions were assessed by the "Attitudes Toward Seeking Professional Psychological Help scale. Both groups were selected from a total of 1,008 individuals who had visited the Centre in four consecutive years. The duration of untreated mental disorders was found to be shorter in group A compared to group B. Males and females of both groups, who had visited the Centre in a time period shorter than 12 months since the onset of their psychopathology, expressed more positive views towards help-seeking, compared to their counterparts with longer duration of untreated mental disorder. The variables of gender (females), age at symptom onset (younger) and education (higher) predicted a shorter duration without psychiatric treatment and more positive views about the necessity of help-seeking. More severe type of diagnoses was associated with shorter durations before accessing care. Our findings underline that mental health awareness programs are clearly required in order to strengthen the early recognition of the need for help- seeking. The development of liaison and outreach activities could also prevent prolonged delays in psychiatric treatment.

Factors associated with abnormal eating attitudes among Greek adolescents.

OBJECTIVE: To estimate the prevalence of abnormal eating attitudes among Greek adolescents and identify possible risk factors associated with these attitudes. DESIGN: Cross-sectional, school-based study. SETTING: Six randomly selected schools in Patras, southern Greece. PARTICIPANTS: The study population consisted of 540 Greek students aged 13-18 years, and the response rate was 97%. MAIN OUTCOME MEASURE: The dependent variable was scores on the Eating Attitudes Test-26, with scores > or = 20 indicating abnormal eating attitudes. ANALYSIS: Bivariate analysis included independent Student t test, chi-square test, and Fisher's exact test. Multivariate logistic regression analysis was applied for the identification of the predictive factors, which were associated independently with abnormal eating attitudes. A 2-sided P value of less than .05 was considered statistically significant. RESULTS: The prevalence of abnormal eating attitudes was 16.7%. Multivariate logistic regression analysis demonstrated that females, urban residents, and those with a body mass index outside normal range, a perception of being overweight, body dissatisfaction, and a family member on a diet were independently related to abnormal eating attitudes. CONCLUSIONS AND IMPLICATIONS: The results indicate that a proportion of Greek adolescents report abnormal eating attitudes and suggest that multiple factors contribute to the development of these attitudes. These findings are useful for further research into this topic and would be valuable in designing preventive interventions.

Oxygenation equilibration time after alteration of inspired oxygen in critically ill patients.

To determine the time required for arterial oxygen partial pressure (Pao(2)) equilibration after a change in fractional inspired oxygen (Fio(2)) in intensive care unit (ICU) patients, a prospective study in a 7-bed university ICU was performed. Forty adult patients were examined using sequential arterial blood gas measurements after a .3 alteration in Fio(2). The Pao(2) value measured at 30 minutes after a step change in Fio(2) in both periods was accepted as representative of the equilibrium value for Pao(2). The mean equilibration time was 8.26+/-5.6 minutes and 4.5+/-2.65 minutes for increases and decreases in Pao(2), respectively (P=.003). The constant k values were .44 +/- .31 minutes and .72 +/- .7 minutes for increases and decreases in Pao(2), respectively. There was no significant difference between the increase and the decrease of 90% oxygenation times in the 2 groups (P=.150 and P=.446, respectively). The study confirms that a period of less than 10 minutes is adequate for 90% of the equilibration of Pao(2) to occur after an Fio(2) change in ICU patients.

"On the spot" interventions by mental health nurses in inpatient psychiatric wards in Greece.

The objective of this research was to explore the "on-the spot" clinical interventions mental health nurses make in critical incidents on inpatient psychiatric wards. Mental health nurses play a key role in the management of psychiatric critical incidents. Nurses' autonomy, decision-making, and training in clinical interventions are important issues in psychiatric nursing practice. A descriptive study was conducted among mental health nurses working on inpatient wards of three major psychiatric hospitals in the greater Athens area, using semi-structured interviews. Nurses' personal views also were documented. Semi-structured interviews were conducted with 103 mental health nurses, who were encouraged to make personal remarks. The results of this study show that in the majority of critical incidents, the nurses were found to be in contact with the psychiatrist on call; physical restraints were used frequently in violent episodes; reassurance and support were common interventions; the majority of nurses would have preferred not to intervene with critical incidents; and nurses expressed a need for skills training and higher autonomy. The nurses implemented a specific number of interventions in confronting the various types of crises. The need for specialized training was noticed and problems like accountability, autonomy, and medication administration, were considered crucial by the mental heath nurses.

Temporal bone and mastoid process morphology in Mediterranean population.

The mastoid process originates from a recent phylogenetic formation and is currently considered as an evolution of the supper-structures bones. The aim of this study was the detailed description of the anatomic elements of the mastoid and the temporal bone in a large Greek adult corpse material. In total, 298 temporal bones from 149 cadaverous (74 male and 75 female) were examined from 1973 through 1993. Concerning the shape of the mastoid apex 94.0% were normal, while the rest presented several variations No statistically significant difference was revealed between genders. The diameters and axis of the temporal bone presented an independent correlation with gender in a multiple regression model. This prescription may add in easier surgical approach by adding new morphological details directly from the corpse material.

Informal payments in public hospitals in Greece.

UNLABELLED: Informal payments are an ingrained social institution in Greece. In some cases, they are also part of corruption in the health area, which includes a variety of other forms. OBJECTIVE: The objective of this paper is to measure and analyze the size and nature of informal payments in the Greek public hospitals, concentrating on payments made to health personnel to facilitate access to services and preferred providers. METHODS: We used a randomized countrywide sample of 1616 households, amounting to 4738 individuals. The survey methodology was telephone interviews with a questionnaire supported by the software of Computer Assisted Telephone Interviewing. RESULTS: Out of the total number of those reporting treatment in public hospitals (N=336), 36% reported at least one informal payment to a doctor. Of these, 42% reported it was given because of the fear of receiving sub-standard care (if they did not pay) and another 20% claimed that the doctor demanded such a payment. None of the socio-economic characteristics of the family were related to the size of extra (informal) payments. The probability of extra payments is 72% higher for patients aiming to "jump the queue", compared to those admitted through normal procedures. Also, surgical cases had a 137% higher probability for extra payments compared to non-surgical patients. CONCLUSIONS: A very high percentage of informal payments are made in order to gain access to public hospitals and to receive a higher quality of services. Despite near universal coverage of the population by public health insurance, informal payments are widespread and a major source of inequity and inefficiency in the Greek health care system.

Quality of life outcome of critical care survivors eighteen months after discharge from intensive care.

AIM: To assess the changes in health-related quality of life in patients discharged from the intensive care unit (ICU). METHODS: At the General University ICU, Trauma Hospital in Athens, 242 patients were enrolled prospectively over a study period of 18 months. Out of these, 116 participants (47.9%) completed all survey components at 6, 12, and 18 months. We used Quality of Life-Spanish (QOL-SP) to assess the health-related quality of life. Patients or their relatives were interviewed on ICU admission and at 6, 12, and 18 months after discharge from the ICU. RESULTS: Mean quality of life score of the patients increased from 2.9+/-4.8 (out of maximum 25 points) on ICU admission to 7.0+/-7.2 points at 6 months after discharge, and then decreased to 5.6+/-6.9 points at 18 months (P<0.001; Friedman Test). Multilinear regression analysis showed that the variables which had the strongest association with the quality of life on admission were age (P=0.002) and male sex (P=0.001), whereas age (P<0.001), length of ICU stay (P<0.001), and male sex (P=0.002) had the strongest association 18 months after discharge from the ICU. Survival rate was 66.9% at discharge from ICU and 61.6% at hospital discharge. There were 33% deaths in the ICU, 5.3% in the hospital, and 6.2% after ICU discharge. There were 7.4% patients lost to follow-up. CONCLUSIONS: After discharge from the ICU, patients' quality of life was poor and showed an improvement at 18 months after discharge, but was still worse than on admission. Age, ICU length of stay, and male sex were the factors that had the strongest impact on the quality of life on admission and at 18 months after discharge from the ICU.

Microalbuminuria: a strong predictor of 3-year adverse prognosis in nondiabetic patients with acute myocardial infarction.

BACKGROUND: The aim of this study is to evaluate the significance of microalbuminuria (MA) as a 3-year prognostic index in nondiabetic patients with acute myocardial infarction (AMI). METHODS: One hundred seventy-five patients with AMI were followed prospectively for 3 years. The study end point was cardiac death or rehospitalization for an acute coronary event. RESULTS: Forty-two patients (24%) developed a new cardiac event during the follow-up. Microalbuminuria (P < .001), pulmonary edema during initial hospitalization (P < .001) and postinfarction angina (P = .0364), advanced age (P = .001), severe atherosclerosis (high Gensini score) (P = .036), ejection fraction <50% (P = .0013), history of bypass surgery (P = .0265), and early conservative management (P = .0214) were all associated with adverse prognosis. Cox proportional hazards regression analysis showed that MA was an independent predictor of 3-year adverse prognosis in all the models tested, with an adjusted relative risk for the development of a cardiac event ranging from 2.1 to 4.3. CONCLUSIONS: In nondiabetic patients with AMI, MA is a strong and independent predictor of an adverse cardiac event within the next 3 years.

Comparison of the effects of ramipril versus telmisartan in reducing serum levels of high-sensitivity C-reactive protein and oxidized low-density lipoprotein cholesterol in patients with type 2 diabetes mellitus.

The effect of ramipril (an angiotensin [AT]-converting enzyme inhibitor), telmisartan (an AT-II type 1 receptor blocker), or their combination on inflammation and lipid peroxidation was assessed in 37 patients with type 2 diabetes who were free of coronary artery disease. All regimens were associated with a significant reduction of C-reactive protein and oxidized low-density lipoprotein cholesterol serum levels (p <0.001). These results further enlighten the mechanisms underlying the cardiovascular beneficial effect of renin-AT system inhibition.
