Complete Blood Count Collected Via Venipuncture Versus Peripherally Inserted Central Catheter in Hematological Patients: A Comparison of 2 Methods.

BACKGROUND: The use of peripherally inserted central catheters (PICCs) in cancer care is increasing over traditional central venous catheters. Nurses frequently collect blood by venipuncture when a PICC is inserted, as there is no available evidence to confirm the reliability of blood tests collected through PICCs in adults. OBJECTIVE: The aim of this study was to assess the reliability of blood samples for complete blood count (CBC) obtained through PICCs as an alternative to venipuncture. METHODS: A cross-sectional design was used to recruit adult hematological patients. The blood samples were collected within 5 minutes of each other by a specialist nurse. Hemoglobin, hematocrit, and platelet count were evaluated. To determine method comparison, Passing-Bablok regression, test of linearity, Pearson product-moment correlation coefficient, and Bland-Altman plots were used. RESULTS: Thirty paired blood samples were collected in 29 hematological patients with a mean age of 66.8 years. A statistical difference was found for hemoglobin (P = .001) and hematocrit (P = .001) levels, but no clinical difference. The regression models revealed no systematic differences and no proportional differences with a linear relationship between the methods. Bland-Altman plots highlighted a good agreement between methods. CONCLUSION: Blood samples for CBC drawn by PICCs are as reliable as those collected via venipuncture. Blood sampling via PICC could be recommended in people with hematological malignancies in needs of frequent blood tests. IMPLICATIONS FOR PRACTICE: Sampling through a PICC provides reliable laboratory results for CBC, and it could reduce patients' discomfort and increase the safety of professionals reducing the risk of accidental percutaneous needlestick injuries.

Factors influencing the perception of protective isolation in patients undergoing haematopoietic stem cell transplantation: A multicentre prospective study.

OBJECTIVES: To identify which factors can influence the patients' perception of protective isolation following Haematopoietic Stem Cell Transplantation (HSCT). METHODS: This is a prospective study conducted in 10 Italian centres, members of the Italian Group of stem cell transplant (GITMO). Patients' perception of protective isolation was assessed using the ISOLA scale between 7 and 9 days post-transplant. Statistical linear regression analysis was performed. RESULTS: The participants were 182 adult patients receiving autologous (48%) or allogeneic (52%) HSCT in protective isolation. Male sex (ß = .152), education level (ß = -.245), double room (ß = .186), satisfaction with visiting hours (ß = -.174) and emotional support from nurses (ß = -.169) were independently associated with isolation-related suffering. Significant predictors of the relationship with oneself included body temperature (ß = -.179), fatigue (ß = -.192) and emotional support from nurses (ß = -.292). Factors independently associated with the relationship with others were education (ß = -.230), chemotherapy cycles (ß = -.218), pain (ß = .150) and satisfaction with visiting hours (ß = -.162). CONCLUSION: Healthcare providers should pay greater attention in caring for those patients who are at risk for a negative isolation experience. Nurses should provide emotional support.

Once-weekly versus twice-weekly carfilzomib in patients with newly diagnosed multiple myeloma: a pooled analysis of two phase I/II studies.

Twice-weekly carfilzomib is approved at 27 and 56 mg/m2 to treat relapsed multiple myeloma patients. In the phase III study ARROW, once-weekly 70 mg/m 2 carfilzomib prolonged the median progression-free survival of relapsed multiple myeloma patients in comparison with twice-weekly 27 mg/m2 carfilzomib, without adding significant toxicity. Data were pooled from two phase I/II studies of newly diagnosed multiple myeloma patients who received nine induction cycles of carfilzomib (either 70 mg/m2 once-weekly or 36 mg/m2 twice-weekly), cyclophosphamide and dexamethasone, followed by carfilzomib maintenance. Overall, 121 transplant-ineligible patients with newly diagnosed multiple myeloma were analyzed (once-weekly, n=63; twice-weekly, n=58). We found no significant difference in median progression-free survival [35.7 months (95%CI: 23.7-not reached, NR) vs 35.5 months (95%CI: 24.3-NR); HR: 1.39; P=0.26] and 3-year overall survival [70% [95%CI: 59%-84%) vs 72% (95%CI: 60%-85%); HR: 1.27; P=0.5] between once-weekly and twice-weekly carfilzomib. From the start of maintenance, 3-year progression-free survival [47% (95%CI: 33%-68%) vs 51% (95%CI: 38%-70%); HR: 1.04; P=0.92] and overall survival [72% (95%CI: 58%-89%) vs 73% (95%CI: 59%-90%); HR: 0.82; P=0.71] were similar in the once- versus twice-weekly carfilzomib. The rate of grade 3-5 hematologic (24% vs 30%; P=0.82) and non-hematologic (38% vs 41%; P=0.83) adverse events was similar in the two groups. Once-weekly 70 mg/m2 carfilzomib as induction and maintenance therapy for newly diagnosed multiple myeloma patients was as safe and effective as twice-weekly 36 mg/m2 carfilzomib and provided a more convenient schedule. The trials are registered at clinicaltrials.gov identifiers: 01857115 (IST-CAR-561) and 01346787 (IST-CAR-506).

An Innovative Model to Predict Pediatric Emergency Department Return Visits.

OBJECTIVES: Return visit (RV) to the emergency department (ED) is considered a benchmarking clinical indicator for health care quality. The purpose of this study was to develop a predictive model for early readmission risk in pediatric EDs comparing the performances of 2 learning machine algorithms. METHODS: A retrospective study based on all children younger than 15 years spontaneously returning within 120 hours after discharge was conducted in an Italian university children's hospital between October 2012 and April 2013. Two predictive models, artificial neural network (ANN) and classification tree (CT), were used. Accuracy, specificity, and sensitivity were assessed. RESULTS: A total of 28,341 patient records were evaluated. Among them, 626 patients returned to the ED within 120 hours after their initial visit. Comparing ANN and CT, our analysis has shown that CT is the best model to predict RVs. The CT model showed an overall accuracy of 81%, slightly lower than the one achieved by the ANN (91.3%), but CT outperformed ANN with regard to sensitivity (79.8% vs 6.9%, respectively). The specificity was similar for the 2 models (CT, 97% vs ANN, 98.3%). In addition, the time of arrival and discharge along with the priority code assigned in triage, age, and diagnosis play a pivotal role to identify patients at high risk of RVs. CONCLUSIONS: These models provide a promising predictive tool for supporting the ED staff in preventing unnecessary RVs.

Development and initial validation of a questionnaire to assess patients' perception of protective isolation following haematopoietic stem cell transplantation.

The aim of this study was to develop and psychometrically test a questionnaire assessing patients' perception of protective isolation following haematopoietic stem cell transplantation (HSCT). The conceptual framework for developing the questionnaire was a three-dimensional model that emerged from a metasynthesis: isolation-related suffering, relationship with oneself and relationship with others. Item selection was performed through a focus group, comparison with the findings of two phenomenological studies, and content validity with 22 experts. Cognitive interviews with five patients were used to verify face validity. A validation study was conducted in 10 Italian centres, all members of the Italian Group of stem cell transplant (GITMO). Patients completed the questionnaires between 7 and 9 days post-transplant. Dimensionality was tested through exploratory factor analysis (EFA). A total of 17 items yielded a content validity index (CVI) of 0.88. Participants included 186 adult patients receiving autologous (48%) or allogeneic (52%) HSCT in protective isolation. The EFA yielded a three-factor solution, explaining 55% of the variance. The scale showed adequate psychometric properties, with the exception of three items, which were eliminated. Future studies should test the psychometric properties of the questionnaire through confirmatory factor analysis and verify its transcultural validity.

Maintenance in myeloma patients achieving complete response after upfront therapy: a pooled analysis.

PURPOSE: Maintenance demonstrated to improve survival in newly diagnosed multiple myeloma (NDMM) patients and the achievement of complete response (CR) is a strong predictor of survival. Nevertheless, the role of maintenance according to response after induction/consolidation has not been investigated so far. To evaluate the impact of maintenance according to response, we pooled together and retrospectively analyzed data from 955 NDMM patients enrolled in two trials (GIMEMA-MM-03-05 and RV-MM-PI-209). METHODS: Primary endpoints were progression-free survival (PFS)1, PFS2 and overall survival (OS) of CR patients randomized to maintenance and no maintenance. Secondary endpoints were PFS1, PFS2 and OS in very good partial response/partial response (VGPR/PR) patients. RESULTS: Overall, 213 patients obtained CR after induction/consolidation, 118 received maintenance and 95 no maintenance. In patients achieving CR, maintenance significantly improved PFS1 (HR 0.50, P < 0.001), PFS2 (HR 0.58, P 0.02) and OS (HR 0.51, P 0.02) compared with no maintenance; the advantage was maintained across all the analyzed subgroups according to age, International Staging System (ISS) stage, cytogenetic profile and treatment. Similar features were seen in VGPR/PR patients. CONCLUSION: Maintenance prolonged survival in CR and in VGPR/PR patients. The benefit in CR patients suggests the importance of continuing treatment in patients with chemo-sensitive disease. TRIAL REGISTRATION: The two source studies are registered at ClinicalTrials.gov: identification numbers NCT01063179 and NCT00551928.

The electronic cigarette phenomenon: prevalence, knowledge and opinion of health care professionals in Italy.

BACKGROUND: Electronic cigarette smoking is spreading among health care professionals. E-cigarette smoke effects on health are not known, especially long-term effects. AIM: The aim of this study was to investigate the phenomenon of electronic cigarettes as regards smoking habits, knowledge and opinions of health care professionals. METHODS: A multicentre cross-sectional descriptive study was conducted by administering an online questionnaire to all the health care professionals employed in two hospitals. RESULTS: The population included 800 employees. More than half (66.8%) of respondents believed the e-cigarette is potentially harmful and capable of attracting young people to smoking and 38.8% of respondents believed that it can serve to stop smoking. The male gender was statistically associated with tobacco and e-cigarette smoking (p=0.034). The electronic cigarette was smoked little at the work place. The population studied did not have any specific knowledge about e-cigarettes and asked for specific training; the population knew the ban on the sale of e-cigarettes to underaged and emphasized the importance of specific management guidelines. CONCLUSIONS: The results of the study show the predominantly negative opinion of health professionals concerning the use of electronic cigarette. Moreover, the study results contributed to an improvement of the smoking policies in the hospitals studied.
