Reliability of cutaneous landmarks for the catheter length assessment during peripherally inserted central catheter insertion: A retrospective observational study.

INTRODUCTION: Peripherally inserted central catheters are very common devices for short, medium and long-term therapies. Their performance is strictly dependent on the correct tip location, at the junction between the upper caval vein and the right atrium. It is very important to obtain an estimated measure of the catheter, in order to reach the cavo-atrial junction and optimize the catheter length. Estimated measures are often obtained using cutaneous landmarks. OBJECTIVE: Evaluate the reliability of cutaneous landmark-based length estimation during catheter insertion. Identify any patient's related factors that may affect cutaneous landmarks reliability. METHODS: We used two distinct techniques and collected data about cutaneous landmark-based length estimation, electrocardiographic guided intravascular length, age, weight and height. We studied the reliability of possible correcting factors, balancing the error average by regression models, and we found and tested two different models of prediction. RESULTS: A total number of 519 patients were studied. The average bias, between the two studied length assessment by cutaneous landmarks and electrocardiographic guided catheter length, were 3.77 ± 2.44 cm and 3.28 ± 2.57 cm, respectively. The analysed prediction models (deviance explained 43.5%, Akaike information criterion = 1313.67% and 43.4%, Akaike information criterion = 1313.92), fitted on the validation set, showed a root mean square error of 3.07 and 3.06. CONCLUSION: Landmark-based length estimation for preventive catheter length assessment seems to be unreliable, when associated with post-procedural tip location. They are useful for distal trimming catheters to optimize the 'out of skin' portion when associated with electrocardiographic tip location. Models identified for balancing bias are probably not useful.

The evaluation of nursing workload within an Italian ECMO Centre: A retrospective observational study.

INTRODUCTION: The Nursing Activities Score (NAS) measures the amount of nursing time required for each patient and it has been widely used across Europe since its first validation in 2003. OBJECTIVE: To determine the nursing workload within an Extracorporeal Membrane Oxygenation (ECMO) Centre using a dedicated scoring tool. METHODS: Retrospective observational study. Data from NAS were collected for seventy-two consecutive months from January 2010. RESULTS: A total amount of 2606 patients were enrolled. Their median NAS recorded at Intensive Care Unit's admission was 69.8 (IQR: 56.2-82.9), whilst the daily average NAS was 68.1 (IQR: 58.3-76.7). ECMO patients enrolled were 95 (4%), with 3141 ECMO days. The median NAS of the ECMO patients versus patients without ECMO support was 87.0 (IQR: 82-96) and 67.2 (IQR: 58-78) respectively (p < 0.0001). The number of daily ECMO treatments showed a slight correlation with the average daily NAS (r = 0.176-p < 0.0001). CONCLUSIONS: Our findings suggest that in ECMO patients a nurse-to-patient ratio equal to 1:1, should be guaranteed in accordance to the national health regulations and organizations. The results of this study reinforce the current recommendation about the implementation of referral ECMO centres, in order to centralise patients, provide a dedicated clinical-technical support and also guarantee an adequate number of ECMO nurses supported by an accurate nurse management.

How different helmet fixing options could affect patients' pain experience during helmet-continuous positive airway pressure.

BACKGROUND: Prolonged application time of helmet continuous positive airway pressure (CPAP) leads to better outcomes, but its timing can be influenced by the patient's tolerance. AIMS AND OBJECTIVES: To investigate patients' pain and tolerance experience related to different options of helmet fixing system: 'armpits strap' versus 'counterweights system'. DESIGN: This was a non-randomized crossover study performed in a 10-bed intensive care unit and referral extra corporeal membrane oxigenation (ECMO) centre of an Italian university hospital. RESULTS: Twenty patients were enrolled. For helmet-CPAP cycles performed with the armpit straps option, the mean pain numerical rate on a 0-10 scale was: 0·5 ± 1·4 at T0 (baseline), 1·5 ± 2·0 at T1 (after 1 h) and 2·6 ± 2·5 at T2 (end of cycle) (p = 0·023). The same analysis was performed for the counterweights fixing option. The mean score was 0·3 ± 0·6 at T0 , 0·3 ± 0·2 at T1 and 0·5 ± 0·7 at T2 (p = 0·069). The mean duration for CPAP cycles performed with armpits strap and counterweights system was 3·0 ± 1·0 and 3·9 ± 2·3 h, respectively (p < 0·001). The mean section of the Basilic vein that was investigated before wearing the helmet was equal to 0·23 ± 0·20 cm2 . After 1 h of therapy with the counterweight option and armpit straps, the mean increase of the vein's section was 0·27 ± 0·21(p = 0·099) and 0·30 ± 0·25, respectively (p = 0·080). CONCLUSIONS: The fixing system options in use to anchor the helmet during CPAP could worsen the pain experience level and cause device-related pressure ulcers. When compared with the armpit straps option, the counterweights system appears to be a suitable approach to minimize the risks of pressure sores and pain during the treatment. RELEVANCE TO PRACTICE: The helmet CPAP is a reliable therapy to manage acute respiratory failure. Major improvements regarding pulmonary alveolar recruitment and oxygen levels are strictly related to a prolonged time of helmet CPAP cycles. Using a counterweight fixing system, where the armpits straps are not necessary, could be helpful in reducing patients' pain experience.

Oral Care Protocols With Specialty Training Lead to Safe Oral Care Practices and Reduce Iatrogenic Bleeding in Extracorporeal Membrane Oxygenation Patients.

INTRODUCTION: Oral care, using either a mouth rinse, gel, toothbrush, or combination of them, together with aspiration of secretions, may reduce the risk of ventilator-acquired pneumonia in intubated patents. Oral care procedure in patients on venovenous extracorporeal membrane oxygenation (VV-ECMO) may cause bleeding due to the systemic anticoagulation required. PURPOSE: The aim of this study was to investigate the rate of bleeding episodes during oral care in patients supported by VV-ECMO. METHODS: A retrospective observational study was performed. All patients admitted to an Italian ECMO center during 2014 were included in the study. RESULTS: Data from 14 patients were analyzed. The median intensive care unit length of stay was 39.0 days (interquartile range, 27.3-83.3 days), and median days on VV-ECMO was 19.5 (10.3-46.0). There were 440 ECMO days, with 1320 oral care maneuvers. In 7 patients, bleeding episodes occurred: 2 with orotracheal intubation and 5 initially managed with orotracheal intubation, thereafter via Translaryngeal tracheostomy tube (according to Fantoni's technique). In 61 oral care procedures (4.6%), bleeding was detected during or after the maneuver, whereas the total numbers of days with at least 1 bleeding episode were 35 (8%).The presence or absence of bleeding during ECMO days was statistically significant for international normalized ratio (1.01 [0.95-1.11] vs 1.13 [1.03-1.25], P < .0001), platelets (163 000 [93 500-229 000] vs 61 000 [91 00-100 000], P < .0001), and mouth care score (6 [5-7] vs 8 [7-9], P < .001). CONCLUSION: Oral care can cause bleeding in patients on VV-ECMO. Implementation of protocols for daily oral care in patients on ECMO may reduce risks. As recommended by the literature, this category of patients should be treated in selected centers distinguished by a regular volume of ECMO activity and the presence of dedicated ECMO specialist nurses.

Application of prone position in hypoxaemic patients supported by veno-venous ECMO.

INTRODUCTION: Veno-Venous Extracorporeal Membrane Oxygenation (VV-ECMO) is an advanced respiratory care therapy allowing replacement of pulmonary gas exchange. Despite VV-ECMO support, some patients may remain hypoxaemic. A possible therapeutic procedure for these patients is the application of prone positioning. OBJECTIVE: The primary aim of the present study was to investigate modification of the PaO2/FiO2 ratio, in VV-ECMO patients with refractory hypoxaemia. The secondary aim was to evaluate the safety and feasibility of prone positioning for patients with severe Adult Respiratory Distress Syndrome supported by ECMO. METHODS: We retrospectively reviewed the electronic records and charts of all patients supported by VV-ECMO who experienced at least one pronation. Complications related with prone positioning were also recorded. First PaO2/FiO2 ratio was analysed during four different time steps: before pronation, one hour after pronation, at the end of pronation and one hour after returning to supine. RESULTS: A total of 45 prone positioning manoeuvers were performed in 14 VV-ECMO patients from November 2009 to November 2014. The median duration of prone positioning cycles was 8 hours (IQR 6-10). No accidental dislodgement of intravascular lines, endotracheal tubes, chest tubes or a decrease in ECMO blood flow was observed. During the first prone positioning for each patient, the median PaO2/FiO2 ratio recorded was 123 (IQR 82-135), 152 (93-185), 149 (90-186) and 113 (74-182), during PRE-supine step, 1 h-prone positioning step, END-prone positioning step, and POST-supine step respectively. CONCLUSIONS: The application of prone positioning during VV-ECMO has shown to be a safe and reliable technique when performed in a recognised ECMO centre with the appropriately trained staff and standard procedures.

Workplace incivility, lateral violence and bullying among nurses. A review about their prevalence and related factors.

BACKGROUND: Negative interactions among nurses are well recognized and reported in scientific literature, even because the issues may have major consequences on professional and private lives of the victims. The aim of this paper is to detect specifically the prevalence of workplace incivility (WI), lateral violence (LV) and bullying among nurses. Furthermore, it addresses the potential related factors and their impact on the psychological and professional spheres of the victims. METHODS: A review of the literature was performed through the research of papers on three databases: Medline, CINAHL, and Embase. RESULTS: Seventy-nine original papers were included. WI has a range between 67.5% and 90.4% (if WI among peers, above 75%). LV has a prevalence ranging from 1% to 87.4%, while bullying prevalence varies between 2.4% and 81%. Physical and mental sequelae can affect up to 75% of the victims. The 10% of bullied nurses develop Post-Traumatic Stress Disorder Symptoms. Bullying is a predictive factor for burnout (ß=0.37 p<0.001) and shows a negative correlation with job efficiency (r=-0 322, p<0.01). Victims of bullying recorded absenteeism 1.5 times higher in comparison to non-victimized peers (95% CI: 1.3-1.7). 78.5% of bullied nurses with length of service lower than 5 years has resigned to move to other jobs. CONCLUSIONS: There is lack of evidence about policies and programmes to eradicate workplace incivility, lateral violence and bullying among nurses. Prevention of these matters should start from spreading information inside continue educational settings and university nursing courses.

Preventing workplace incivility, lateral violence and bullying between nurses A narrative literature review.

Introduction: according to available literature workplace incivility, lateral violence and bullying among nurses are widely diffused. Their negative consequences and the outcomes on nurses and healthcare organizations have been well described. However, real pro-active and reactive actions to manage these issues, seem to be poorly recognized and investigated. AIM: to summarize the results of international studies regarding the prevention of individual and collective reactions towards workplace incivility, lateral violence, and bullying between nurses. METHODS: a narrative literature review was performed. RESULTS: 7 original papers were included in this review. The implementation of zero tolerance policies and passive dissemination of information about these phenomena showed to be clearly ineffective. CONCLUSIONS: The limited number of evidence based studies and the typologies of interventions (mainly educational rather than team building programs and assertive communication) show inadequate effectiveness plus a lacking in the scientific evidence-based support. The need to find out innovative and "creative" solutions to face these problems has been suggested by different authors.

Noninvasive ventilation: open issues for nursing research.

According to the current literature, Noninvasive Ventilation (NIV) is a well-recognized respiratory support technique for patients affected by Acute Respiratory Failure (ARF). As highlighted by recent meta-analysis, a tight adherence to protocols regarding patients' selection criteria, relative or absolute contraindications, plus highly skilled and experienced operators, can positively affect the NIV performance and mortality rates. Positive outcome from NIV respiratory support is dependent from: patient's clinical condition and education needs; confidence of the staff with NIV technology; choice and management of the most suitable interface available prevention of interface complications; nutritional assessment (artificial feeding if required) and conditioning of medical gas. Despite these issues, the air leakage represents the major threat during NIV support. Indeed, to obtain a positive outcome from this treatment, the 'NIV troubleshooting' management appears to be crucial. Common issues as air leakage, patient-ventilator asynchrony, interface related pressure ulcers, discomfort, and gastric distention should be promptly detected and solved. The analysis of these current issues reveals a lack of evidence based practice, resulting in bed-side clinical interventions based only on the expert consensus or local opinions. To improve this knowledge gap, more efforts are strongly recommended from medical and nursing research communities. Multicenter randomized controlled clinical trials are needed to achieve adequate knowledge to reach the best patient's outcome. Further information to identify new areas of nursing research on NIV, can be achieved from qualitative studies performed on patients and healthcare operators.

Nursing Activities Score (NAS): 5 years of experience in the intensive care units of an Italian University hospital.

OBJECTIVE: To retrospectively analyse the application of the Nursing Activities Score (NAS) in an intensive care department from January 2006 to December 2011. METHOD: The sample consists of 5856 patients in three intensive care units (GICU: General Intensive Care Unit, NeuroICU: Neurosurgical Intensive Care Unit, CICU: Cardiothoracic Intensive Care Unit) of an Italian University hospital. The NAS was calculated for each patient every 24 hours. In patients admitted to general ICU, the following scores: SAPS 2 and SAPS 3 (Simplified Acute Physiology Score), RASS (Richmond Agitation Sedation Scale) and Braden were also recorded along with the NAS. RESULTS: The mean NAS for all patients was 65.97% (Standard Deviation ± 2.53), GICU 72.55% (± 16.28), NeuroICU 59.33% (± 16.54), CICU 63.51% (SD ± 14.69). The average length of hospital stay (LOS) was 4.82 (SD ± 8.68). The NAS was high in patients with increasing LOS (p<0.003) whilst there were no significant differences for age groups except for children 0-10 years (p<0.002). The correlation of NAS and SAPS 2 was r=0.24 (p=0.001), NAS and SAPS 3 r=-0.26 (p=0.77), NAS and RASS r=-0.23 (p=0.001), NAS and Braden r=0.22 (p=0.001). CONCLUSIONS: This study described the daily use of the NAS for the determination of nursing workload and defines the staff required.
