Cost and reimbursement analysis of end-of-life cancer inpatients. The case of the Greek public healthcare sector.

BACKGROUND: While hospital-based Palliative Care services are usually covered through the main funding healthcare framework, traditional reimbursement methods have been criticized for their appropriateness. The present study investigates for the first time the case of treating end-of-life cancer patients in a Greek public hospital in terms of cost and reimbursement. METHODS: This retrospective observational study used health administrative data of 135 deceased cancer patients who were hospitalized in the end of their lives. Following the cost estimation procedure, which indentified both the individual patient and overhead costs, we compared the relevant billing data and reimbursement requests to the estimated costs. RESULTS: The average total cost per patient per day was calculated to be 97 EUR, with equal participation of individual patient's and overhead costs. Length of stay was identified as the main cost driver. Reimbursement was performed either by per-diem fees or by Diagnosis Related Groups' (DRGs), which were correspondingly associated with under or over reimbursement risks. In the case of the combined use of the two available reimbursement alternatives a cross-subsidization phenomenon was described. CONCLUSION: Although the cost of end-of-life care proved to be quite low, the national per-diem rate fails to cover it. DRGs designed for acute care needs are rather unsuitable for such sub acute hospitalizations. POLICY SUMMARY: There is a concrete need for reconsidering the current reimbursement schemes for this group of patients as part of any national plan concerning the integration and reformation of Palliative Care services. Otherwise, there is a serious danger for public institutions' reluctance to admit them with a serious impact on access and equity of end-of-life cancer care.

Scales for assessing medication adherence in patients with hypertension.

BACKGROUND: the choice of the appropriate tool for assessing level of medication adherence is a significant barrier in scientific research. AIMS: to translate into Greek and test the reliability of the Hill-Bone and A-14 scales among patients with hypertension. Also, to compare patients' responses in the Hill-Bone scale, A-14 scale and Morisky Medication Adherence Scale (MMAS). METHODS: data collection occurred between February 2016 and March 2016 at a general hospital in Athens, Greece. The sample consisted of hypertensive patients (n=34) and non-hypertensive patients (n=34). FINDINGS: the coefficient alpha in hypertensive patients was 0.76 for Hill-Bone, 0.64 for MMAS and 0.91 for the A-14 scale. In non-hypertensive patients, the Cronbach's alpha for MMAS was 0.81 and 0.78 for A-14. A statistically significant difference was found among the mean scores of the scales, whereas strong correlation was found only between two pairs of questions with similar meaning. CONCLUSION: all tools are appropriate to assess the level of medication adherence in Greek hypertensive patients. However, careful translation of the scales is essential since items with the same meaning could be understudied in a different way.

Necessity of the Periodical Ultrasound Assessment of the Peripheral Venous System in Intensive Care Unit Patients.

The utility of periodic sonographic assessment and monitoring for early diagnosis of deep vein thrombosis (DVT) in patients hospitalized in intensive care units (ICUs) was investigated. Of 314 patients hospitalized in an ICU over a 24-mo period, 248 were examined. The first examination of the patients was carried out within the first 48 h of ICU admission, and weekly examination followed until discharge. Peripheral veins were examined according to the general principles of the ultrasound study using the compression test in B-mode imaging (image to gray scale). The criterion for the absence or presence of a clot within the lumen was the presence or absence of full compressibility of the venous lumen, respectively. Intermittent compression was applied to multiple cross sections along the entire extent of the limbs. Three patients (1.2%) were diagnosed with sub-clinical DVT. The diagnoses were made on the third (sapheno-femoral junction), fourth (right internal jugular) and fifth (left gastrocnemius) weeks of hospitalization, respectively, although patients received full anticoagulation prophylaxis. DVT in a general-population ICU patient on anticoagulation prophylaxis did not seem to occur very frequently, and hence, regular ultrasound monitoring is not recommended. However, it may have value after the third week or in a selected population of ICU patients with very severe and/or multiple predisposing factors or who are not undergoing anticoagulant treatment because of contraindications.

Circadian disruption of ICU patients: A review of pathways, expression, and interventions.

Intensive care unit patients typically exhibit pathologic wakefulness, poor quality of daytime sleep, nocturnal sleep fragmentation, and sleep patterns that feature the absence of slow wave sleep and rapid eye movement. This article offers a review of the existing literature examining circadian desynchronization in critically ill patients, highlighting contributing factors identified by scholars, and circadian abnormalities observed in these patients. It discusses potential implications for clinical practice and suggests avenues of future research. Elucidating the role of circadian rhythms in the management of critical illness can guide future chronotherapeutic approaches and optimize patient outcomes.

Variable cost of ICU care, a micro-costing analysis.

Intensive care unit (ICU) costs account for a great part of a hospital's expenses. The objective of the present study was to measure the patient-specific cost of ICU treatment, to identify the most important cost drivers in ICU and to examine the role of various contributing factors in cost configuration. A retrospective cost analysis of all ICU patients who were admitted during 2011 in a Greek General, seven-bed ICU and stayed for at least 24hours was performed, by applying bottom-up analysis. Data collected included demographics and the exact cost of every single material used for patients' care. Prices were yielded from the hospital's purchasing costs and from the national price list of the imaging and laboratory tests, which was provided by the Ministry of Health. A total of 138 patients were included. Variable cost per ICU day was €573.18. A substantial cost variation was found in the total costs obtained for individual patients (median: €3443, range: €243.70-€116,355). Medicines were responsible for more than half of the cost and antibiotics accounted for the largest part of it, followed by blood products and cardiovascular drugs. Medical cause of admission, severe illness and increased length of stay, mechanical ventilation and dialysis were the factors associated with cost escalation. ICU variable cost is patient-specific, varies according to each patient's needs and is influenced by several factors. The exact estimation of variable cost is a pre-requisite in order to control ICU expenses.

Adrenergic Effect on Cytokine Release After Ex Vivo Healthy Volunteers' Whole Blood LPS Stimulation.

Catecholamines are molecules with immunomodulatory properties in health and disease. Several studies showed the effect of catecholamines when administered to restore hemodynamic stability in septic patients. This study investigates the effect of norepinephrine and dobutamine on whole blood cytokine release after ex vivo lipopolysaccharide (LPS) stimulation. Whole blood collected from healthy individuals was stimulated with LPS, in the presence of norepinephrine or dobutamine at different concentrations, with or without metoprolol, a ß1 receptor antagonist. Cytokine measurement was performed in isolated cell culture supernatants with ELISA. Results are expressed as mean ± SEM and compared with Mann-Whitney rank-sum test. Both norepinephrine and dobutamine significantly reduced TNF-α and IL-6 production after ex vivo LPS stimulation of whole blood in a dose-dependent manner, and this effect was partially reversed by the presence of metoprolol. Norepinephrine and dobutamine reduce the LPS-induced production of pro-inflammatory cytokines, thus possibly contributing to altered balance between the inflammatory and anti-inflammatory responses, which are vital for a successful host response to severe disease, shock, and sepsis.

Can nurse-led preoperative education reduce anxiety and postoperative complications of patients undergoing cardiac surgery?

BACKGROUND: The effect of preoperative education on anxiety and postoperative outcomes of cardiac surgery patients remains unclear. AIM: The aim of the study was to estimate the effectiveness of a nurse-led preoperative education on anxiety and postoperative outcomes. METHODS: A randomised controlled study was designed. All the patients who were admitted for elective cardiac surgery in a general hospital in Athens with knowledge of the Greek language were eligible to take part in the study. Patients in the intervention group received preoperative education by specially trained nurses. The control group received the standard information by the ward personnel. Measurements of anxiety were conducted on admission-A, before surgery-B and before discharge-C by the state-trait anxiety inventory. RESULTS: The sample consisted of 395 patients (intervention group: 205, control group: 190). The state anxiety on the day before surgery decreased only in the intervention group (34.0 (8.4) versus 36.9 (10.7); P=0.001). The mean decrease in state score during the follow-up period was greater in the intervention group (P=0.001). No significant difference was found in the length of stay or readmission. Lower proportions of chest infection were found in the intervention group (10 (5.3) versus 1 (0.5); P=0.004). Multivariate linear regression revealed that education and score in trait anxiety scale on admission are independent predictors of a reduction in state anxiety. CONCLUSION: Preoperative education delivered by nurses reduced anxiety and postoperative complications of patients undergoing cardiac surgery, but it was not effective in reducing readmissions or length of stay.

First Peripherally Inserted Central Catheter Under Ultrasound Guidance in a Greek Intensive Care Unit: A New Role for Greek Perianesthesia Nurses.

We present a case of a 67-year-old Caucasian female who was admitted to the pulmonary clinic of a general hospital in Athens with fever and respiratory symptoms. A lung biopsy was ordered because a clinical diagnosis of interstitial lung disease was suspected. The patient was then hospitalized in the intensive care unit. Because of the fact that peripheral catheterization was impossible and the prospect of further long-term hospitalization, the patient was referred to a vascular access nursing team composed of perianesthesia nurses to advance a peripherally inserted central catheter and support the line during treatment. The peripherally inserted central catheter line was advanced with no complications, and the position of the catheter was checked using the electrocardiography method.

Translation and validation of the Greek version of the hypertension knowledge-level scale.

AIMS AND OBJECTIVES: To translate and validate a Greek version of the Hypertension Knowledge-Level Scale. BACKGROUND: The major barrier in the management of hypertension is the lack of adherence to medications and lifestyle adjustments. Patients' knowledge of the nature of hypertension and cardiovascular risk factors is a significant factor affecting individuals' adherence. However, few instruments have been developed to assess patients' knowledge level and no one has been translated into Greek. DESIGN: This study used a case control study design. METHODS: Data collection for this research occurred between February 7, 2013 and March 10, 2013. The sample included both hypertensives and non-hypertensives. Participants simultaneously completed the version of the Hypertension Knowledge-Level Scale. A total of 68 individuals completed the questionnaire. RESULTS: Coefficient alpha was 0·66 for hypertensives and 0·79 for non-hypertensives. The difference for the mean scores in the entire scale between the two samples was statistically significant. In addition, significant differences were observed in many sub-dimensions and no correlation was found between level, knowledge and age, gender and education level. CONCLUSIONS: Findings provide support for the validity of the Greek version of the Hypertension Knowledge-Level Scale. RELEVANCE TO CLINICAL PRACTICE: The translation and validation of an instrument evaluating the level of knowledge of hypertension contribute to assessing the provided educational intervention. Low knowledge level should lead to the development of new methods of education, therefore nurses will have the opportunity to amplify their role in patients' education and develop relationships based on honesty and respect.

Neuroprotective Effects of Erythropoietin in Patients with Severe Closed Brain Injury.

AIM: Our research was focused on the neuroprotective function of erythropoietin (Epo) in patients with severe closed traumatic brain injury (TBI). MATERIAL AND METHODS: Our model examined the influence of the outcome and neurological recovery in 42 adults with TBI who were admitted to ICU within 6 hours of their injury and were recruited into a randomized controlled study of two groups; only the patients of the intervention group received 10,000 i.u. of Epo for 7 consecutive days. A prognostic model based on CRASH II injury model and outcome was measured by survival and Glasgow Outcome Scale-Extended version (GOS-E) score at 6 months post-injury. RESULTS: Six patients (18.7%) died during the first two weeks; 4 of the control group and 2 of the intervention group. A mortality rate of 22.2% and 8.3% for the control and intervention group respectively was observed. A lower rate of good outcome (GOS-E score > 4) at 6 months was mentioned among patients of the control group. CONCLUSION: The study provides evidence of lower mortality and better neurological outcome for the patients who received Epo increasing the possibility that Epo therapy could be used in clinical practice, limiting neuronal damage induced by TBI.

Health-related quality of life and rehabilitation cost following intensive care unit stay in multiple trauma patients.

OBJECTIVES: The objective of this study was to assess changes in health-related quality of life (HRQOL) in multiple trauma patients due to motor vehicle crashes during a follow-up period of 2 years after discharge from an intensive care unit (ICU) and the effect of income and financial cost of rehabilitation in HRQOL. METHODS: The study was a prospective observational study of multiple trauma patients from January 2009 to January 2011 who were hospitalized in a general, medical, and surgical ICU of a district hospital in Athens, Greece. Eighty-five patients with multiple traumas due to motor vehicle crashes and with an ICU stay of more than 24 hours were included in the study. HRQOL was assessed by a general questionnaire, the EuroQol 5D. RESULTS: Increased monthly household income and absence of traumatic brain injuries were associated with an improved EQ-VAS score. The frequency of severe problems in mobility, self-care, usual activities, pain/discomfort, and anxiety/depression decreased over time. The financial cost of rehabilitation was initially high but decreased over time. CONCLUSIONS: Severely injured victims of motor vehicle crashes suffer from serious problems in terms of HRQOL which is gradually improved even 2 years after hospital discharge. In addition, HRQOL is significantly related to income. Resources used for rehabilitation decrease over time, but even at 24 months, the patients still use half of the amount as compared with the cost of the first 6 months after trauma.

The immune response after stimulation with wall components of gram-positive bacteria and fungi.

Although several components of the microbial wall of gram-positive bacteria and fungi possess immunostimulatory properties, their pathogenetic role remains incompletely evaluated. The purpose of this study was to assess the basic immune status of patients susceptible to infections and their capability for cytokine production after stimulation with wall components of gram-positive bacteria and fungi. We measured serum cytokine levels as well as cytokine production after ex vivo lipoteichoic acid (LTA) and mannan stimulation of whole blood. The blood was taken from 10 healthy volunteers, 10 patients with end-stage renal disease (ESRD), 10 patients with diabetes mellitus (DM), and 10 patients on their 2nd day of stay in the Intensive Care Unit (ICU), who suffered from non septic systemic inflammatory response syndrome (SIRS) and had an APACHE II score ≥25. We used 1 µg/ml LTA and 100 µg/ml mannan for an incubation period of 8 h to stimulate 100 µl aliquots of whole blood. All patient groups had higher baseline values of TNF-α, IL-6, IL-1ß, and IL-10 compared to the control group, but only for ICU patients the difference was statistically significant. The ratio IL-10/IL-6 was found 0.33, 0.22, and 0.96 in healthy persons, ESRD, and DM patients respectively, and 1.32 in ICU patients. In all examined groups, the levels of cytokines significantly increased after stimulation by LTA and mannan, although in severely ill patients this change was considerably smaller, possibly reflecting a state of monocytes' depression and relative hyporesponsiveness. No significant differences between the LTA and the mannan stimulation were observed.

Nursing Activities Score as a predictor of family satisfaction in an adult intensive care unit in Greece.

AIM: To study family satisfaction with care in an Intensive Care Unit (ICU) and its association with nursing workload estimated by the Nursing Activities Score (NAS). BACKGROUND: Few previous studies have investigated the association between workload in ICUs and family satisfaction. METHODS: Family Satisfaction ICU 24 (FS ICU-24) questionnaires were distributed to 161 family members (106 respondents). Questionnaires' score, NAS measurements and Simplified Acute Physiology Score II (SAPS-II) data were analysed. RESULTS: The mean total level of family satisfaction was equal to 80.72% (± 9.59). Family members were more satisfied with the level of care compared with decision making. NAS values revealed a shortage of nurses in the morning shift. Moreover, there was a statistically significant positive correlation between NAS and total satisfaction after adjusting for age, length of stay and SAPS-II. CONCLUSIONS: Improvements in clinical practice require the measurement of care quality which particularly includes family satisfaction. Our results indicated that family members were less satisfied with decision making. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers should plan for the successful involvement of family members in the decision-making process. Higher levels of nurse staffing might improve the care provided.

Spirometry may underestimate airway obstruction in professional Greek athletes.

PURPOSE: Lung development and consequently, lung volumes, are affected by the duration, type and intensity of sporting. Athletes may have higher spirometric values compared to predicted which may lead to misclassification of this population and misdiagnosis during clinical evaluation. The aim of the study was to compare measured spirometric values with those predicted from the European Community for Steel and Coal statement in Greek professional athletes. METHODS: Measured and predicted spirometric values were recorded from 276 normal professional athletes (168 males, 108 females), aged 15-60 years originated from the metropolitan area of Athens, Greece. Predicted and measured spirometric values were compared using a paired sample t-test and analysed using Bland-Altman method. RESULTS: Measured FEV1 was 109.6 (1.02%) and 109.4 (1.29%) and FVC was 110.8 (1.07%) and 109.6 (1.02%) compared to predicted in males and females respectively. The FEV1 /FVC ratio was 102.2 (0.55%) and 103.2 (0.58%) compared to predicted for males and females, respectively. Bland-Altman analysis revealed a significant bias and magnitude of difference between predicted and measured spirometric values. CONCLUSIONS: European Community for Steel and Coal predicted spirometric values significantly underestimated measured lung volumes and FEV1 /FVC ratio in Greek athletes of both sexes. Predicted spirometric indices should be used with caution in the evaluation of athletes presenting with respiratory symptoms for the risk of underestimation of restrictive disease or airway obstruction.

A higher tidal volume may be used for athletes according to measured FVC.

We investigated whether professional athletes may require higher tidal volume (Tv ) during mechanical ventilation hypothesizing that they have significantly higher "normal" lung volumes compared to what was predicted and to nonathletes. Measured and predicted spirometric values were recorded in both athletes and nonathletes using a Spirovit SP-1 spirometer (Schiller, Switzerland). Normal Tv (6 mL/kg of predicted body weight) was calculated as a percentage of measured and predicted forced vital capacity (FVC) and the difference (δ) was used to calculate the additional Tv required using the equation: New Tv(TvN) = Tv + (Tv × Î´). Professional athletes had significantly higher FVC compared to what was predicted (by 9% in females and 10% in males) and to nonathletes. They may also require a Tv of 6.6 mL/kg for males and 6.5 mL/kg for females during mechanical ventilation. Nonathletes may require a T v of 5.8 ± 0.1 mL/kg and 6.3 ± 0.1 mL/kg for males and females, respectively. Our findings show that athletes may require additional Tv of 10% (0.6/6 mL/kg) for males and 8.3% (0.5/6 mL/kg) for females during general anesthesia and critical care which needs to be further investigated and tested.

Unplanned extubation in critically ill adults: clinical review.

AIMS AND OBJECTIVES: To investigate and synthesize the evidence on the incidence and consequences of unplanned extubation (UE) in intensive care unit (ICU) patients, and on risk factors for UE. BACKGROUND: ICU patients generally spend considerable time being intubated via the endotracheal route. Non-planned endotracheal tube removal, either deliberate or accidental, may pose significant safety risks for them. As UE is among the most studied critical incidents in the ICU, evaluation and summary of existing findings could provide important implications for clinical practice. SEARCH STRATEGIES, INCLUSION AND EXCLUSION CRITERIA: Observational studies published between 1990 and 2012 in English-language journals indexed by Cumulative Index for Nursing and Allied Health Literature (CINAHL), PubMed, Web of Science and the Cochrane Library were searched for studies on UE of critically ill adults. Thirty-three articles were considered eligible for inclusion. CONCLUSIONS: UE incidence varies considerably among reports, with self-extubation representing the majority of cases. Agitation, especially when combined with inadequate sedation, and decreased patient surveillance are the major risk factors for UE. Inexperienced personnel and improper tube fixation may also be important, while physical restraint use remains controversial. UE can be followed by serious complications, mainly aspiration, laryngeal oedema and increased risk for pneumonia. Need for re-intubation is a major determinant of patient outcomes. Implementation of educational or quality improvement programs is expected to advance personnel's knowledge about risk factors for UE, promote skills on safe, standardized procedures for patient care and increase compliance with them. RELEVANCE TO CLINICAL PRACTICE: Identifying risk factors for UE and minimizing UE incidence through appropriate preventive strategies are prerequisites for improving nursing care quality and patient safety in the ICU.

Role of new biomarkers: functional and structural damage.

Traditional diagnosis of acute kidney injury (AKI) depends on detection of oliguria and rise of serum creatinine level, which is an unreliable and delayed marker of kidney damage. Delayed diagnosis of AKI in the critically ill patient is related to increased morbidity and mortality, prolonged length of stay, and cost escalation. The discovery of a reliable biomarker for early diagnosis of AKI would be very helpful in facilitating early intervention, evaluating the effectiveness of therapy, and eventually reducing cost and improving outcome. Innovative technologies such as genomics and proteomics have contributed to the discovery of new biomarkers, such as neutrophil gelatinase-associated lipocalin (NGAL), cystatin C (Cys C), kidney injury molecule-1 (KIM-1), interleukin-18 (IL-18), and liver-type fatty acid binding protein (L-FABP). The current status of the most promising of these novel AKI biomarkers, including NGAL, Cys C, KIM-1, L-FABP, and IL-18, is reviewed.

Fever effects and treatment in critical care: literature review.

Considering that the incidence of fever may reach up to 75% among critically ill adults, healthcare professionals employed in the Intensive Care Unit (ICU) are called to evaluate and manage patient temperature elevation on a daily basis. This literature review synthesizes the evidence about the effects of fever and antipyretic treatment in ICU patients. Although the febrile response acts protectively against infections, noxious effects are possible for patients with cerebral damage, neuropsychiatric disorders or limited cardiorespiratory reserve. Observational studies on ICU populations have reported associations between fever magnitude and patient mortality. Especially recent findings indicated that infected patients may significantly benefit from temperature elevation, while high fever may be maladaptive for non-infected ones. Aggressive antipyretic treatment of ICU patients has not been followed by decreased mortality in randomized trials. However, fever suppression and return to normothermia improved outcomes of septic shock patients. Antipyretic treatment should begin with drug administration and proceed with external cooling in case of refractory fever, but adverse effects of both antipyretic methods should always be considered. This article concludes by providing implications for antipyretic treatment of critically ill adults and suggesting areas for future research.

The continuing question of how fever duration is associated with patient outcome.

Although fever magnitude and etiology have been associated with outcomes of critically ill patients, possible associations between fever duration and mortality remain inconclusive. Since long-lasting fever is generally attributed to severe pathologic conditions, it is expected to be an indicator of adverse outcome. It also seems plausible that persistent fever in specific patient groups, mainly those with cerebral damage or limited cardiorespiratory reserve, could lead to worsened outcomes. Existing studies on these associations have been considerably limited because of methodological flaws, which may account for controversial findings that have been reported. Well-designed, large-sample studies using diverse measures of fever duration need to be conducted.
