Heparin versus normal saline locking for prevention of occlusion, catheter-related infections and thrombosis in central venous catheter in adults: Overview of systematic reviews.

Venous access devices are used in health care. To prevent occlusions the evidence confirmed the need for routine catheter flushing before and after infusion as well as at the end of use. To date, the efficacy of heparin has not been demonstrated. The aim of this study was to evaluate the effectiveness of the locking of central venous catheters with heparin versus normal saline in adults to prevent occlusion, catheter-related infections and thrombosis in adults. A literature search using Medline, Embase, Cochrane Library and Cinahl was performed to identify all meta-analyses addressing the effectiveness of heparin versus normal saline in locking central venous catheters in adults. Four reviewers independently selected publications assessed quality and extracted data. Parameter estimates regarding occlusion, catheter- related infections and thrombosis were pooled using an umbrella review. We identified 6356 references. Seven systematic reviews were included in the study. Most of the studies included in the systematic reviews were conducted in oncohaematology departments, intensive care and cardiac surgery units among patients with multiple diseases and chronicity. Most studies report a heparin concentration of 10 to 5000 IU/ml versus normal saline and other solutions. There was no evidence that heparin was more effective than normal saline in reducing complications such as occlusion, catheter-related infections and thrombosis. No statistically significant difference was found between heparin and normal saline in reducing catheter occlusion. Heparin is not superior compared to normal saline.

Short Versus Long Timing of Flushing of Totally Implantable Venous Access Devices When Not Used Routinely: A Systematic Review and Meta-analysis.

BACKGROUND: Flushing and locking of totally implantable venous access devices (TIVADs) is recommended to maintain their patency when not in use. Although manufacturers' recommendations indicate monthly access for TIVAD maintenance, there is a tendency in real life to prolong this interval. OBJECTIVES: To assess the effectiveness of prolonged versus short flushing and locking intervals to prevent TIVAD occlusions in adults with cancer. METHODS: A systematic search was carried out in MEDLINE, EMBASE, CINAHL, and Web of Science. Two reviewers independently selected studies, assessed quality, and extracted data. Study findings were summarized, and a meta-analysis conducted. RESULTS: Six articles were included in the review, with a total of 1255 participants. Differences in types of cancers, flushing and locking techniques, and volume and concentration of heparin were described. Pooled results from 4 studies showed fewer catheter occlusions in favor of prolonged flushing and locking intervals (relative risk, 0.81), even if not statistically significant (95% confidence interval, 0.41-1.61) with no heterogeneity among studies (I2 = 0.00%, P = .69). The quality of evidence was very low. CONCLUSIONS: Very low-quality evidence suggests that prolonged schedule flushing and locking intervals has no effect on catheter patency. However, because of low number and poor quality of evidence derived from the studies analyzed, findings of this meta-analysis should be interpreted with caution. IMPLICATIONS FOR PRACTICE: No statistically significant difference in occlusion rate between short and long timing of flushing was found. However, further studies are necessary to strengthen the safe implementation of longer intervals in clinical practice.

Pain prevalence, severity, assessment and management in hospitalized adult patients: a result of a multicenter cross sectional study.

INTRODUCTION: The measurement of pain prevalence among the patients admitted to hospital, estimated that pain remains a common problem for patients. METHODS: This is a multi-center cross sectional study carried out in Italian Hospitals, where data was collected in only one day. All patients aged at least 18 years, hospitalized able or unable to communicate, were eligible to be included in the study. Patients with curarization or quadriplegia (any cause) were excluded. RESULTS: Some hospitals and residential structures took part in our research, 26 centers in total. Pain prevalence has been observed in 268 patients (38%) (95% CI = 34%-41%) (range within wards 31-47%). Women are at higher risk than men (RR = 1.59, 95% CI = 1.29-1.95). Pain prevalence was more observed at 10.9 (+ 1.46) days after surgery. Severe pain has been observed in 148 (21.2%) cases. Pain was managed in 223 (83.2%) cases, and it was predominantly treated with the administration of paracetamol (n = 55; 24.7%) within 30 minutes after having ascertained the presence of pain. CONCLUSIONS: Pain is reported by about 4 out of 10 adults, with a higher prevalence of cases in women, and its appearance does not depend on the care setting. In order to assess the prevalence of pain carefully, an Italian study that involves all regions and a large number of the centers may be necessary.

Effects of prolonged flushing interval in totally implantable venous access devices (TIVADs).

Totally implantable venous access device (TIVAD) lumen occlusion is a long-term complication of central venous catheters, associated with risks of infection, therapy interruptions and increased healthcare costs. The role of flushing and locking in maintaining TIVAD patency is paramount. Most flushing protocols are based on manufacturers' recommendations, which indicate that 4 weeks is the safest interval between two consecutive flushing procedures during periods when TIVADs are not in use. Conversely, results of several studies suggest that extended flushing intervals (FIs) do not increase the rate of obstructive or infective complications. The study aimed to describe the effects of prolonged FIs in a cohort of 317 patients with cancer. The authors found no significant difference in terms of TIVAD problems between long (>45 days) and short (≤45 days) FI groups, which raises questions over the validity of current practice.

Quit attempts and smoking cessation in Italian adults (25-64 years): factors associated with attempts and successes.

Background: Over the past 50 years there was a substantial decrease in the prevalence of smoking in Italy. The objective of this work is to describe attempts to quit and cessation success in Italian smokers. Methods: A surveillance on health-related behaviors (PASSI) was conducted in 2007-13 on a sample of 203 610 Italian adults 25-64 years of age. An analysis of smokers' characteristics and behaviors was performed, focusing on attempts to quit and quit success. Data from national surveys (ISTAT) from 1983 to 2013 (Italian adults, 25-64 years of age, 1983: 46 634; 1987: 40 915; 1990: 36 622; 2000: 77 531; 2005: 71 032; 2013: 64 205) were used to explore if a cessation trend in Italy exists. Results: Smokers who quit in the previous year and were still abstinent when interviewed increased from 1990 to 2013. In the years 2011-13, 38% of people who had smoked in the last 12 months reported at least a quit attempt during the same period and 7% were still abstinent when interviewed. An association of successful recent quit attempts with higher educational level, absence of economic difficulties and younger age was found. In the years 2007-13, the great majority tried to stop unaided. Having received assistance from a cessation program did not increase the probability of enduring abstinence. Conclusions: In Italy interventions to drive more smokers to quit should be focused in particular on disadvantaged groups. Initiatives have to be studied not only to incentive more smokers to try to quit, but also to maintain abstinence over time.

Pressure Ulcers in Older Adults: A Prevalence Study.

OBJECTIVE: The purpose of this study was to measure the prevalence of pressure ulcers (PrUs) in an older adult population. DESIGN: A cross-sectional study. SETTING: The study included all the individuals being cared for in the units of medicine, surgery, intensive care, and medical-surgical specialties of 47 hospitals, 57 public nursing homes, and 37 home care services. PARTICIPANTS: The authors' observational study included 11,957 patients older than 70 years. MAIN OUTCOME MEASURES: Of the population, 50.75% (6067) were assessed to be at risk of developing PrUs according to the Braden Scale, and 24.66% (2949) had already developed PrUs. In addition, a significant association was found between increased risk (Braden <16) and the presence of PrUs with an odds ratio (OR) of 8.71 (confidence interval [CI], 7.52-10.10) in high-risk subjects (Braden ≤ 12) and an OR of 3.86 (CI, 3.36-4.44) in very high-risk patients (Braden 13-16). In the survey, 84.6% of the subjects with PrUs were incontinent, and incontinence increased the risk of developing PrUs in the authors' sample (OR, 1.54; CI, 1.34-1.77). CONCLUSIONS: The authors' data reported in the literature show that the prevalence of PrUs increases as an individual ages. The authors gathered data that showed a large area of intervention in managing the prevention of PrUs, such as an adequate use of protective aids, correcting malnutrition, and controlling incontinence. These results suggest that clinicians should focus more on the prevention of PrUs in older adults.

Normal saline versus heparin solution to lock totally implanted venous access devices: Results from a multicenter randomized trial.

PURPOSE: Our aim was to determine the non-inferiority of normal saline flushing compared to heparin flushing in maintaining the patency of totally implanted venous access devices (TIVADs). METHOD: Four hundred and thirty patients were recruited from 14 Italian centres. Patients were randomized to heparin group or to normal saline group. The primary outcome of the study was TIVAD occlusion. RESULTS: After randomisation, 203 patients were assigned to normal saline group and 212 to heparin group. Median follow up time was 204 days in normal saline group and 294 in the heparin group. We observed 24 withdrawal occlusions (5.78%): 10 in the heparin group and 14 in the normal saline group. One total occlusion was observed in the normal saline group. Taking as reference the arm treated with heparin, the absolute risk difference was 2.67 with the 90% CI including the non - inferiority margin of 4%. No significant difference between hazards of occlusion was found. CONCLUSIONS: This study failed to demonstrate that normal saline flushing is not inferior to heparin flushing, even if a significant difference between the two treatments was not found. The use of heparin is controversial and other prospective trials are necessary in this field. TRIAL REGISTRATION: EudraCT number: 2009-013620-22.

[Assessing the effectiveness of Gelclair® in the prevention and therapy of stomatitis in patients undergoing hematopoietic stem-cell transplantation: a randomized trial]. / Valutazione dell'efficacia del Gelclair® nella prevenzione e cura della stomatite nei pazienti sottoposti a trapianto di cellule staminali emopoietiche: Studio randomizzato.

INTRODUCTION: Chemotherapy-induced stomatitis is a major side effect of the treatment. Numerous approaches are described in the literature for the prevention and treatment of this complication. OBJECTIVE: the aim was assess the effectiveness of Gelclair® in patients undergoing hematopoietic stem-cell transplantation in terms of reducing the incidence of stomatitis, stomatitis-pain and the severity of stomatitis INTERVENTIONS/METHODS: Fifty-seven patients (28 control group and 29 experimental group) used a mouthwash 3 times a day and were evaluated by means of a specially-tailored form containing the following assessment items:stomatitis evaluation scale (WHO), VAS for pain and Likert-Scale for agreement. RESULTS: 61% of patients presented with stomatitis. No difference was observed between the two groups with regard to stomatitis grade throughout the observation period. Painful symptoms were observed in 54% subjects. No differences were observed in terms of average pain perception before the use of mouthwashes throughout the period of observation p=0.06. RESULTS showed a pain-relieving effect in the experimental group after using the mouthwash p=0.04. CONCLUSIONS: Although Gelclair® had no influence on the onset and severity of stomatitis in transplanted patients, a significant benefit was observed in terms of pain control. Our study suggest the possibility to implementation the use of Gelclair® in clinical practice. However, further multicenter trials are needed to provide stronger evidence on the real usefulness of this product.

Totally implantable central venous access ports in patients with cystic fibrosis: a multicenter prospective cohort study.

PURPOSE: The aim of this study was to assess the incidence of late onset complications of totally implantable venous access devices (TIVAD) in patients with cystic fibrosis (CF) and to investigate possible associations between the rate of complications and different policies of TIVAD management. METHODS: A multicenter prospective cohort study was performed in 11 Italian CF Centers. Patients with CF and a TIVAD were recruited and followed-up. RESULTS: The study commenced on May 2008 and ended on September 2010. Eighty subjects were studied (77.5% women--mean age 27.2 years). Eighteen late complications of ports were observed (22.5%; incidence 0.96 per 1000 days of observation): three lumen occlusions, seven catheter-related infections , three port-related venous thrombosis, in addition to five other complications. A statistically significant association was found between the onset of catheter-related infection and the presence of CF-related diabetes (CFRD) (P=.0064) CONCLUSIONS: Our data suggest that TIVADs represent a safe and effective device for the intermittent IV administration of drugs in people with CF. However, people with CFRD have a higher risk of developing TIVAD-related infection.

The late complications of totally implantable central venous access ports: the results from an Italian multicenter prospective observation study.

PURPOSE: The principal aim of this study is to analyze the incidence of late complications in oncologic patients with totally implanted central venous access ports. METHODS: A prospective multicenter observational study was conducted in 26 Italian oncologic outpatient clinics. 1076 cancer patients with Totally Implanted Central Venous Access Ports (TIAP) were observed. 515 devices were observed in patients under treatment and 561 in patients who went to the outpatient clinic only for flushing. RESULTS: Late complications observed in patients under treatment were: 3 pocket infections (0.09/1000 days of port observation), 1 cutaneous infection (0.03/1000 days of port observation), 8 occlusions (0.24/1000 days of port observation) and 12 others. In patients using the device only for flushing we observed 4 cases of device related bacteremia (0.04/1000 days of port observation), 1 pocket infection (0.01/1000 days of port observation), 1 cutaneous infection (0.01/1000 days of port observation), 3 occlusions (0.03/1000 days of port observation) and 7 other complications. CONCLUSIONS: The low incidence of complications suggests that TIAP is safe and reliable for long term intermittent venous access. Our results support the use of TIAP in the oncology patients.
