Incidence and risk factors for central venous access device failure in hospitalized adults: A multivariable analysis of 1892 catheters.

BACKGROUND: Central venous access devices (CVADs) allow intravenous therapy, haemodynamic monitoring and blood sampling but many fail before therapy completion. OBJECTIVE: To quantify CVAD failure and complications; and identify risk factors. DESIGNS, SETTINGS AND PARTICIPANTS: Secondary analysis of multicentre randomised controlled trial including patients aged ≥16 years with a non-tunnelled CVAD (NTCVAD), peripherally-inserted central catheter (PICC) or tunnelled CVAD (TCVAD). Primary outcome was incidence of all-cause CVAD failure (central line-associated bloodstream infection [CLABSI], occlusion, accidental dislodgement, catheter fracture, thrombosis, pain). Secondary outcomes were CLABSI, occlusion and dislodgement. Cox regression was used to report time-to-event associations. RESULTS: In 1892 CVADs, all-cause failure occurred in 10.2% of devices: 49 NTCVADs (6.1%); 100 PICCs (13.2%); 44 TCVADs (13.4%). Failure rates for CLABSI, occlusion and dislodgement were 5.3%, 1.8%, and 1.7%, respectively. Independent CLABSI predictors were blood product administration through PICCs (hazard ratio (HR) 2.62, 95% confidence interval (CI) 1.24-5.55); and in TCVADs, one or two lumens, compared with three to four (HR 3.36, 95%CI 1.68-6.71), intravenous chemotherapy (HR 2.96, 95%CI 1.31-6.68), and diabetes (HR 3.25, 95%CI 1.40-7.57). Independent factors protective for CLABSI include antimicrobial NTCVADs (HR 0.23, 95%CI 0.08-0.63) and lipids in TCVADs (HR 0.32, 95%CI 0.14-0.72). NTCVADs inserted at another hospital (HR 7.06, 95%CI 1.48-33.7) and baseline infection in patients with PICCs (HR 2.72, 95%CI 1.08-6.83) were predictors for dislodgement. No independent occlusion predictors were found. Modifiable risk factors were identified for CVAD failure, which occurred for 1-in-10 catheters. Strict infection prevention measures and improved CVAD securement could reduce CLABSI and dislodgement risk.

Central Venous Access Device-Associated Skin Complications in Adults with Cancer: A Prospective Observational Study.

OBJECTIVES: To identify the prevalence and type of central venous access device-associated skin complications for adult cancer patients, describe central venous access device management practices, and identify clinical and demographic characteristics associated with risk of central venous access device-associated skin complications. METHODS: A prospective cohort study of 369 patients (626 central venous access devices; 7,682 catheter days) was undertaken between March 2017 and March 2018 across two cancer care in-patient units in a large teaching hospital. RESULTS: Twenty-seven percent (n = 168) of participants had a central venous access device-associated skin complication. In the final multivariable analysis, significant (P < .05) risk factors for skin complications were cutaneous graft versus host disease (2.1 times greater risk) and female sex (1.4 times greater risk), whereas totally implanted vascular access device reduced risk for skin complications by two-thirds (incidence risk ratio 0.37). CONCLUSION: Central venous access device-associated skin complications are a significant, potentially avoidable injury, requiring cancer nurses to be aware of high-risk groups and use evidence-based preventative and treatment strategies. IMPLICATIONS FOR PRACTICE: This study has confirmed how common these potentially preventable injuries are. Therefore, the prevalence of these complications could be reduced by focusing on improvements in skin assessment, reductions in central venous access device dressing variation and improving clinician knowledge of this injury.

A randomised trial of topical polaprezinc to prevent oral mucositis in patients undergoing haematopoietic stem cell transplantation (ToPaZ study).

PURPOSE: Oral mucositis (OM) is a common complication in haematopoietic stem cell transplantation (HSCT). Polaprezinc, an anti-ulcer drug, has been shown to be effective to prevent OM in several studies when administered topically and systemically. This study aimed to evaluate the effectiveness of topical polaprezinc in patients undergoing HSCT. METHODS: This was an open-label randomised clinical trial comparing polaprezinc and sodium bicarbonate mouthwashes for the prevention of severe OM in HSCT patients. Adult patients who received conditioning regimens at moderate to high risk of developing OM were included. The primary endpoint was the incidence of severe (WHO grades 3-4) OM. The secondary endpoints included duration of grades 3-4 OM, incidence and duration of grades 2-4 OM, patient-reported pain and functional limitations. RESULTS: In total, 108 patients (55 test arm and 53 control arm) were randomised. There was no difference in the incidence of grades 3 to 4 OM (35% test arm versus 36% control arm). The secondary endpoints were not significantly different. In both arms, patients reported more throat pain compared to mouth pain. CONCLUSIONS: Topical polaprezinc had no effect in the prevention of OM in HSCT patients. Further research is required to evaluate the effects of systemic polaprezinc. The OM assessment tool needs to be reviewed as throat mucositis was a main issue in this study. TRIAL REGISTRATION: ACTRN12320001188921 (Date Registered: 10th November 2020).

Peripheral intravenous catheter material and design to reduce device failure: A systematic review and meta-analysis.

BACKGROUND: Patients require vascular access for medical treatments, diagnostic procedures and symptom management. Current failure rates of peripheral intravascular catheters (PIVCs) are unacceptably high (40-50%). This systematic review aimed to determine the effect of different PIVC materials and designs on the incidence of PIVC failure. METHODS: A systematic search was conducted in November 2022 using CINAHL, PubMed, EMBASE and Cochrane Central Register of Controlled Trials databases. Randomised controlled trials that compared PIVC novel PIVC material/design and standard material/design were included. The primary outcome was all causes of PIVC failure, any reason for device removal due to cessation of device function; and secondary outcomes included individual PIVC complications and infection (local or systemic), and dwell times. Quality appraisal was conducted using the Cochrane risk of bias tool. A meta-analysis was performed using random effects model. RESULTS: Seven randomised controlled trials were eligible for inclusion. In meta-analysis, the impact of material and design on PIVC failure in the studies favoured the intervention arms (RR 0.71, 95% CI 0.57-0.89), however there was substantial heterogeneity (I2 = 81%, 95% CI 61-91%). Through subgroup analyses, a significant difference on PIVC failure favoured the closed system over the open system (RR 0.85, 95% CI 0.73 to 0.99; I2 = 23%, 95% CI 0-90%). CONCLUSION: Catheter material and design can impact PIVC outcome. Conclusive recommendations are limited due to the small number of studies and inconsistent reporting of clinical outcomes. Further rigorous research of PIVC types is necessary to improve clinical practice and device selection pathways should reflect the resulting evidence.

Association between parenteral nutrition-containing intravenous lipid emulsion and bloodstream infections in patients with single-lumen central venous access: A secondary analysis of a randomized trial.

BACKGROUND: Distinguishing primary bloodstream infections (BSIs) related to central venous access devices (CVADs) from those that occur through other mechanisms, such as a damaged mucosal barrier, is difficult. METHODS: Secondary analysis was conducted on data from patients with CVADs that were collected for a large, randomized trial. Patients were divided into two groups: those who received parenteral nutrition (PN)-containing intravenous lipid emulsion (ILE) and those who did not have PN-containing ILE. This study investigated the influence of PN-containing ILE (ILE PN) on primary BSIs in patients with a CVAD. RESULTS: Of the 807 patients, 180 (22%) received ILE PN. Most (627/807; 73%) were recruited from the hematology and hematopoietic stem cell transplant unit, followed by surgical (90/807; 11%), trauma and burns (61/807; 8%), medical (44/807; 5%), and oncology (23/807; 3%). When primary BSI was differentiated as a central line-associated BSI (CLABSI) or mucosal barrier injury laboratory-confirmed BSI (MBI-LCBI), the incidence of CLABSI was similar in the ILE PN and non-ILE PN groups (15/180 [8%] vs 57/627 [9%]; P = 0.88) and the incidence of MBI-LCBI was significantly different between groups (31/180 [17%] ILE PN vs 41/627 [7%] non-ILE PN; P < 0.01). CONCLUSION: Our data indicate that twice as many primary BSIs in ILE PN patients are due to MBIs than CVADs. It is important to consider the MBI-LCBI classification, as some CLABSI prevention efforts aimed at CVADs for the ILE PN population may be better directed to gastrointestinal tract protection interventions.

Perforated intravenous catheter design is acceptable for the administration of contrast-enhanced computed tomography administration in cancer patients: Results of a pilot randomised controlled trial.

BACKGROUND: Optimising first time success of peripheral intravenous catheter (PIVC) insertion and reducing intravenous (IV) complications in cancer patients undergoing contrast-enhanced computed tomography (CT) is vital to ensure vascular access preservation and diagnostic accuracy. The aim of this study was to test the feasibility of a randomised controlled trial (RCT) evaluating a novel perforated PIVC compared to a standard PIVC. METHODS: A single centre, parallel-group, pilot RCT was conducted between March and May 2020. Adult participants diagnosed with cancer were randomised to a non-perforated PIVC (standard care) or a PIVC with a novel perforated design (intervention) for the administration of IV contrast. There were two primary outcomes: (1) feasibility of an adequately powered RCT with pre-established criteria; and (2) all-cause PIVC failure. Secondary outcomes included: first insertion success, modes of PIVC failure, dwell time, contrast injection parameters (volume and injection rate), contrast enhancement, radiographer satisfaction and adverse events. RESULTS: Feasibility outcomes were met, except for eligibility (⩾90%) and recruitment (⩾90%). In total, 166 participants were screened, 128 (77%) were eligible and of these 101/128 (79%) were randomised; 50 to standard care and 51 to intervention. First time insertion rate was 94% (47/50) in standard care and 90% (46/50) in intervention. The median dwell time was 37 minutes (interquartile range (IQR): 25-55) in standard care and 35 minutes (IQR: 25-60) in the intervention group. There was one PIVC failure, a contrast media extravasation, in the intervention group (1/51; 2%). The desired contrast injection rate was not achieved in 4/101 (4%) of participants; two from each group. Radiographers were satisfied with the contrast flow rate. CONCLUSIONS: This pilot RCT suggests perforated PIVCs provide expected flow rate, with no evidence of differences in contrast enhancement to non-perforated PIVCs. The feasibility of conducting a larger powered RCT was demonstrated.

The incidence of severe oral mucositis in patients undergoing different conditioning regimens in haematopoietic stem cell transplantation.

PURPOSE: Oral mucositis is a common complication during haematopoietic stem cell transplantation (HSCT). This study aimed to assess the incidence of severe mucositis in patients undergoing different HSCT regimens. METHODS: This single-centre retrospective study reviewed daily oral assessment for 467 consecutive patients who underwent different transplant regimens for matched unrelated or related allogeneic HSCT with post-transplant methotrexate, haploidentical or mismatched HSCT with post-transplant cyclophosphamide (PTCy), or autologous HSCT. Oral care and cryotherapy with melphalan were used. Patient demographic data, oral mucositis WHO grade, use of total parenteral nutrition (TPN) and patient-controlled analgesia (PCA) were collected. RESULTS: Grade 3-4 oral mucositis was common in myeloablative total body irradiation (TBI)-based regimens cyclophosphamide/ TBI (CyTBI) (71%) and fludarabine/ TBI (FluTBI) with PTCy (46%), as well as reduced-intensity fludarabine/melphalan (FluMel) (43%) and carmustine/etoposide/cytarabine/melphalan (BEAM) autologous HSCT (41%). In contrast, grade 3-4 oral mucositis was less common in reduced-intensity haploidentical regimen melphalan/fludarabine/TBI with PTCy (19%), all non-myeloablative regimens (0-9%) and high-dose melphalan autologous HSCT (26%). TPN and PCA use were correlated to oral mucositis severity. CONCLUSIONS: Severe oral mucositis was associated with myeloablative TBI, methotrexate and melphalan in combination with methotrexate and in BEAM. Use of PTCy was preferable over methotrexate to prevent oral mucositis.

Clinicians' Understanding of Preferences and Values of People with Hematological Malignancies at the End of Life: Concurrent Surveys.

Background: People with hematological malignancies can deteriorate rapidly to a terminal event and have variable levels of engagement when transitioning to palliative and end-of-life care. Objectives: To describe end-of-life care values and preferences of people with hematological malignancies and explore whether these align with hematology clinicians' perceptions. Design: Two matched anonymous quantitative cross-sectional surveys explored: (1) patients' values and preferences around manner and timing of discussions regarding life expectancy and prognosis, involvement in decision making, and concurrent integration of palliative care with active treatment; and (2) clinicians' perceptions of their patients' values and preferences in relation to prognostic information. Settings/Participants: Concurrent online national surveys of people with hematological malignancies known to the Leukemia Foundation of Australia, and clinicians in Australia with membership to the Hematology Society of Australia and New Zealand. Results: Five hundred nine (38% response rate) patients (median age 64 [min 20, max 89, interquartile range 56-70]) and 272 clinicians (21% response rate) responded to the survey. If their health was deteriorating, most patients wanted honest prognostic and life expectancy information (87%); welcomed involvement in decision making (94%); felt they would be comfortable talking to the treating team about the possibility of death (86%); and would be comfortable seeing someone from a specialist palliative care team (74%). Clinicians generally underestimated most of these responses. Conclusion: Although our findings indicate that most people believe they would be comfortable discussing prognosis, life expectancy, and wishes at the end of life, clinicians were largely unaware of their preferences. This highlights the need to embed values clarification in routine care for each patient and family.

Implementation and evaluation of a nurse-allied health clinic for patients after haematopoietic stem cell transplantation.

PURPOSE: Patients who undergo haematopoietic stem cell transplantation (HSCT) often have multiple health issues following hospital discharge. In many centres, outpatient follow-up is solely conducted by specialist physicians. We aimed to implement and describe the outcomes of a nurse-allied health multidisciplinary clinic. METHODS: The clinic consisted of six disciplines-nursing, pharmacy, dietetics, physiotherapy, occupational therapy and social work. All allogeneic and high risk autologous HSCT patients were reviewed at 2 weeks after discharge and on day 100 post HSCT, with additional reviews as needed. Occasions of service, interventions, readmission data and physician satisfaction survey were collected prior to and after implementation. Additionally, patient feedback and quality of life survey (FACT-BMT) were collected during the first 6 months. RESULTS: From July to December 2019, 57 patients were reviewed in the clinic (475 reviews, average 8.3 reviews per patient). Common interventions included the following: exercise programs by physiotherapist (n = 111), diet prescription (n = 103), counselling by social worker (n = 53), medication lists provision (n = 51), fatigue management (n = 43) and nurse education (n = 22). The clinic did not reduce patients' readmission rate; however, positive feedback from patients and physicians were reported. FACT-BMT results demonstrated that there are unmet needs, particularly fatigue management, sexual education and support, body images, back to work support and quality of life improvement. From discharge to day 100, there was no significant improvement in quality of life. CONCLUSIONS: This clinic provides an innovative approach to patient-centred care in HSCT. It has been well received by patients who were supported by multidisciplinary interventions.

A real-world accuracy of oral mucositis grading in patients undergoing hematopoietic stem cell transplantation.

PURPOSE: Oral mucositis is a common complication in patients undergoing hematopoietic stem cell transplantation. Accurate oral mucositis grading is essential for both clinical practice and oral mucositis research. This study aimed to evaluate the accuracy of daily oral mucositis grading by nurses in a tertiary hospital in Australia. METHODS: A retrospective study was undertaken to review the daily patient oral assessment record, including diet, pain, erythema, ulceration and the oral mucositis grade based on World Health Organization (WHO) oral mucositis grading scale. The accuracy of the grade was determined by the observations recorded, and reasons for inaccuracy were documented. Any repetition of the same error in the same patient was noted. RESULTS: In total, 6841 oral assessments in 373 patients, conducted between 2017 and 2020, were reviewed. A total of 70% (N = 4781) were graded correctly. Of these, 64% (N = 3043) were grade 0. When the grade 0 scores were excluded, the accuracy of grading was reduced to 46% (N = 1738). Common reasons for incorrect grading included: unable to grade due to diet not specified, no ulceration and no pain was scored grade 1, no ulceration was scored as grade 2-4, oral intake was not taken into account, and pain without ulcer was scored 0. A total of 77% of the errors were repeated in the same patient on consecutive days. CONCLUSIONS: Our results suggest there is frequent inaccurate evaluation of oral mucositis and a need for nurse training to accurately assess oral mucositis.

Prospective cohort study of an Australian cancer care services-led model of emergent care.

ObjectiveMany cancer care services (CCS) provide pragmatic models of emergent care for their patients as part of 'business as usual' without understanding the scope of this work. We aimed to describe an Australian CCS-led model of emergent care and quantify and profile emergent care provided over a 6-month period to understand scope and demand.MethodsThis prospective cohort study was performed at a large tertiary hospital on the eastern coast of Australia in 2016. The study explored emergent care provided during business hour and after-hours, including telephone advice, unplanned care and unplanned admissions. Data were collected via electronic hospital records and clinical nurses regarding who accessed care, why care was accessed, what care was provided and how the episode of care ended.ResultsBetween March and September 2016, 1412 episodes of unplanned care were provided in the CCS-led model of care, including 307 episodes of telephone advice (237 patients; min max 1-4 episodes per patient; 825 episodes of unplanned care (484 patients; min max 1-9 episodes per patient) and 280 unplanned admissions (233 patients; min max 1-6 episodes per patient). During the same time, an additional 459 unplanned admissions (361 patients) occurred via the emergency department (ED), of which 125 (27.2%) occurred during business hours which could have been managed by the CCS. Most people who received care experienced issues associated with disease or treatment and had received systemic anticancer therapy in the past 30 days.ConclusionsThe data demonstrate that a significant volume of emergent care was provided within the CCS over the study period, in addition to planned cancer treatment. Due to the ever-increasing demands on EDs and the significant need for emergent care for people with cancer, there is need for CCS-led models of care to provide specialist emergent care specifically for people who are receiving systemic anticancer therapy. Such models must be adequately resourced to meet the needs of patients, carers and healthcare professionals.What is known about the topic?There is increasing focus on innovative models of emergent care for people with cancer in the out-patient setting to relieve pressure on EDs and improve patient experiences. Limited literature has focused on such models in the Australian context.What does this paper add?This paper describes, quantifies and profiles care provided in a pragmatic CCS-led model of emergent care in a large tertiary hospital in Australia over 6 months. The data demonstrate significant demand for emergent care within business hours, as well as out of hours, predominantly for people undergoing systemic anticancer therapy.What are the implications for practitioners?The findings of this study highlight the need for CCS to develop pragmatic models of emergent care. Appropriate resources, infrastructure, policies and procedures are required to adequate meet the needs of patients and carers.

Effect of infusion set replacement intervals on catheter-related bloodstream infections (RSVP): a randomised, controlled, equivalence (central venous access device)-non-inferiority (peripheral arterial catheter) trial.

BACKGROUND: The optimal duration of infusion set use to prevent life-threatening catheter-related bloodstream infection (CRBSI) is unclear. We aimed to compare the effectiveness and costs of 7-day (intervention) versus 4-day (control) infusion set replacement to prevent CRBSI in patients with central venous access devices (tunnelled cuffed, non-tunnelled, peripherally inserted, and totally implanted) and peripheral arterial catheters. METHODS: We did a randomised, controlled, assessor-masked trial at ten Australian hospitals. Our hypothesis was CRBSI equivalence for central venous access devices and non-inferiority for peripheral arterial catheters (both 2% margin). Adults and children with expected greater than 24 h central venous access device-peripheral arterial catheter use were randomly assigned (1:1; stratified by hospital, catheter type, and intensive care unit or ward) by a centralised, web-based service (concealed before allocation) to infusion set replacement every 7 days, or 4 days. This included crystalloids, non-lipid parenteral nutrition, and medication infusions. Patients and clinicians were not masked, but the primary outcome (CRBSI) was adjudicated by masked infectious diseases physicians. The analysis was modified intention to treat (mITT). This study is registered with the Australian New Zealand Clinical Trials Registry ACTRN12610000505000 and is complete. FINDINGS: Between May 30, 2011, and Dec, 9, 2016, from 6007 patients assessed, we assigned 2944 patients to 7-day (n=1463) or 4-day (n=1481) infusion set replacement, with 2941 in the mITT analysis. For central venous access devices, 20 (1·78%) of 1124 patients (7-day group) and 16 (1·46%) of 1097 patients (4-day group) had CRBSI (absolute risk difference [ARD] 0·32%, 95% CI -0·73 to 1·37). For peripheral arterial catheters, one (0·28%) of 357 patients in the 7-day group and none of 363 patients in the 4-day group had CRBSI (ARD 0·28%, -0·27% to 0·83%). There were no treatment-related adverse events. INTERPRETATION: Infusion set use can be safely extended to 7 days with resultant cost and workload reductions.

A comparison of hydrophobic polyurethane and polyurethane peripherally inserted central catheter: results from a feasibility randomized controlled trial.

BACKGROUND: To evaluate the feasibility of an efficacy trial comparing a hydrophobic polyurethane peripherally inserted central catheter (PICC) with a standard polyurethane PICC. METHODS: This pilot randomised controlled trial (RCT) was conducted between May 2017 and February 2018. Adult participants (n = 111) were assigned to hydrophobic polyurethane PICC with proximal valve (intervention) or a polyurethane PICC with external clamp (standard care). Primary outcome was trial feasibility including PICC failure. Secondary outcomes were central line-associated bloodstream infection, local infection, occlusion, thrombosis, fracture and dislodgement, phlebitis, local or systemic allergic reaction, and PICC dwell time. RESULTS: All feasibility outcomes were achieved, apart from eligibility criteria. In total, 338 patients were screened, 138 were eligible (41%), and of these 111 were randomised (80%). Patients received the allocated PICC in 106 (95%) insertions. No patients withdrew from the study and there was no missing data. PICC failure was 24% (13/55) in the intervention group and 22% (12/55) in the standard care group (p = 0.820). PICC failure per 1000 PICC days was 16.3 in the intervention group and 18.4 in the control group (p = 0.755). The average dwell time was 12 days in the intervention and 8 days in the control group. CONCLUSIONS: This study demonstrates the feasibility of an efficacy trial of PICC materials in an adult population, once adjustments were made to include not only in-patients, but also patients being discharged to the Hospital in the Home service. TRIAL REGISTRATION: Australia and New Zealand Clinical Trials Registry ACTRN12616001578493 . Prospectively registered on 16 November 2016. The trial protocol was published a priori (Kleidon et al., Vasc Access 3:15-21, 2017).

Harnessing the power of clinician judgement. Identifying risk of deteriorating and dying in people with a haematological malignancy: A Delphi study.

AIM: To provide expert consensus on the clinical indicators that signal a person with a haematological malignancy is at high risk of deteriorating and dying. BACKGROUND: Identification of people who are at risk of deteriorating and dying is essential to facilitate patient autonomy, appropriate treatment decisions, and effective end-of-life care. DESIGN: A three-step modified Delphi approach. METHODS: The study was conducted over 6 months (September 2015-March 2016) to gather opinion from an international panel of experts (N = 27) on the clinical indicators that signal a person with a haematological malignancy is at high risk of deteriorating and dying. The first round was informed by a systematic review of prognostic factors present in the final months of life for people with a haematological malignancy. Consensus was achieved if 70% of responses fell within two points on a seven-point Likert-type scale. FINDINGS: Consensus was achieved on the following 11 clinical indicators: (a) advancing age; (b) declining performances status; (c) presence of co-morbidities; (d) disease status; (e) persistent infections (bacterial and viral); (f) fungal infections; (g) severe graft versus host disease; (h) requiring high care; (i) signs of frailty; (j) treatment limitations; and (k) anorexia and/or weight loss. Consensus was also achieved on associated themes and statements for each indicator. CONCLUSION: The findings of this study indicate that subjective clinician-assessed indicators that are contextually relevant to the nature of haematological malignancies are markers of risk. This study has provided valuable preliminary findings on the topic and will inform future research.

Clinical Indicators That Identify Risk of Deteriorating and Dying in People with a Hematological Malignancy: A Case-Control Study with Multivariable Analysis.

BACKGROUND: Identifying people who are at risk of deteriorating and dying is essential to inform goals of care, appropriate treatment decisions, patient autonomy, and effective end-of-life care. Limited literature exists on predicting survival near the end of life for people with a hematological malignancy. OBJECTIVE: To identify the key clinical indicators that signal a person with a hematological malignancy is at high risk of deteriorating and dying. DESIGN, SETTING, PARTICIPANTS: Eleven clinical indicators identified in a Delphi approach were tested via a retrospective case-control study. Each indicator was assessed for at each in-patient admission between living (n = 236) and deceased (n = 120) people with a hematological malignancy who were admitted to a large tertiary hospital between 1st July 2014 and 31st December 2015. RESULTS: Six clinical indicators were independently associated with mortality in the final three months of life: declining performance status (Odds Ratio [OR] 7.153, 95% Confidence Intervals [CI] 3.281-15.597, p = < 0.001); treatment limitations of the hematological malignancy (OR 7.855, 95% CI 3.528-17.489, p = < 0.001); relapse, refractory or persistent disease (OR 3.749, 95% CI 1.749-8.039, p = 0.001); presence of two or more comorbidities (OR 2.991, 95% CI 1.319-6.781, p = 0.009); invasive fungal infections (OR 4.887, 95% CI 1.197-19.949, p = 0.027); and persistent infections (OR 6.072, 95% CI 2.551-14.457, p = < 0.001). CONCLUSIONS: This study has identified six clinical indicators that signal a person with a hematological malignancy is at high risk of deteriorating and dying and may benefit from an assessment of palliative needs and proactive planning, along-side appropriate treatment.

Peripherally InSerted CEntral catheter dressing and securement in patients with cancer: the PISCES trial. Protocol for a 2x2 factorial, superiority randomised controlled trial.

INTRODUCTION: Around 30% of peripherally inserted central catheters (PICCs) fail from vascular, infectious or mechanical complications. Patients with cancer are at highest risk, and this increases morbidity, mortality and costs. Effective PICC dressing and securement may prevent PICC failure; however, no large randomised controlled trial (RCT) has compared alternative approaches. We designed this RCT to assess the clinical and cost-effectiveness of dressing and securements to prevent PICC failure. METHODS AND ANALYSIS: Pragmatic, multicentre, 2×2 factorial, superiority RCT of (1) dressings (chlorhexidine gluconate disc (CHG) vs no disc) and (2) securements (integrated securement dressing (ISD) vs securement device (SED)). A qualitative evaluation using a knowledge translation framework is included. Recruitment of 1240 patients will occur over 3 years with allocation concealment until randomisation by a centralised service. For the dressing hypothesis, we hypothesise CHG discs will reduce catheter-associated bloodstream infection (CABSI) compared with no CHG disc. For the securement hypothesis, we hypothesise that ISD will reduce composite PICC failure (infection (CABSI/local infection), occlusion, dislodgement or thrombosis), compared with SED. SECONDARY OUTCOMES: types of PICC failure; safety; costs; dressing/securement failure; dwell time; microbial colonisation; reversible PICC complications and consumer acceptability. Relative incidence rates of CABSI and PICC failure/100 devices and/1000 PICC days (with 95% CIs) will summarise treatment impact. Kaplan-Meier survival curves (and log rank Mantel-Haenszel test) will compare outcomes over time. Secondary end points will be compared between groups using parametric/non-parametric techniques; p values <0.05 will be considered to be statistically significant. ETHICS AND DISSEMINATION: Ethical approval from Queensland Health (HREC/15/QRCH/241) and Griffith University (Ref. No. 2016/063). Results will be published. TRIAL REGISTRATION: Trial registration number is: ACTRN12616000315415.

Frequency of dressing changes for central venous access devices on catheter-related infections.

BACKGROUND: People admitted to intensive care units and those with chronic health care problems often require long-term vascular access. Central venous access devices (CVADs) are used for administering intravenous medications and blood sampling. CVADs are covered with a dressing and secured with an adhesive or adhesive tape to protect them from infection and reduce movement. Dressings are changed when they become soiled with blood or start to come away from the skin. Repeated removal and application of dressings can cause damage to the skin. The skin is an important barrier that protects the body against infection. Less frequent dressing changes may reduce skin damage, but it is unclear whether this practice affects the frequency of catheter-related infections. OBJECTIVES: To assess the effect of the frequency of CVAD dressing changes on the incidence of catheter-related infections and other outcomes including pain and skin damage. SEARCH METHODS: In June 2015 we searched: The Cochrane Wounds Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. We also searched clinical trials registries for registered trials. There were no restrictions with respect to language, date of publication or study setting. SELECTION CRITERIA: All randomised controlled trials (RCTs) evaluating the effect of the frequency of CVAD dressing changes on the incidence of catheter-related infections on all patients in any healthcare setting. DATA COLLECTION AND ANALYSIS: We used standard Cochrane review methodology. Two review authors independently assessed studies for inclusion, performed risk of bias assessment and data extraction. We undertook meta-analysis where appropriate or otherwise synthesised data descriptively when heterogeneous. MAIN RESULTS: We included five RCTs (2277 participants) that compared different frequencies of CVAD dressing changes. The studies were all conducted in Europe and published between 1995 and 2009. Participants were recruited from the intensive care and cancer care departments of one children's and four adult hospitals. The studies used a variety of transparent dressings and compared a longer interval between dressing changes (5 to15 days; intervention) with a shorter interval between changes (2 to 5 days; control). In each study participants were followed up until the CVAD was removed or until discharge from ICU or hospital. Confirmed catheter-related bloodstream infection (CRBSI)One trial randomised 995 people receiving central venous catheters to a longer or shorter interval between dressing changes and measured CRBSI. It is unclear whether there is a difference in the risk of CRBSI between people having long or short intervals between dressing changes (RR 1.42, 95% confidence interval (CI) 0.40 to 4.98) (low quality evidence). Suspected catheter-related bloodstream infection Two trials randomised a total of 151 participants to longer or shorter dressing intervals and measured suspected CRBSI. It is unclear whether there is a difference in the risk of suspected CRBSI between people having long or short intervals between dressing changes (RR 0.70, 95% CI 0.23 to 2.10) (low quality evidence). All cause mortalityThree trials randomised a total of 896 participants to longer or shorter dressing intervals and measured all cause mortality. It is unclear whether there is a difference in the risk of death from any cause between people having long or short intervals between dressing changes (RR 1.06, 95% CI 0.90 to 1.25) (low quality evidence). Catheter-site infectionTwo trials randomised a total of 371 participants to longer or shorter dressing intervals and measured catheter-site infection. It is unclear whether there is a difference in risk of catheter-site infection between people having long or short intervals between dressing changes (RR 1.07, 95% CI 0.71 to 1.63) (low quality evidence). Skin damage One small trial (112 children) and three trials (1475 adults) measured skin damage. There was very low quality evidence for the effect of long intervals between dressing changes on skin damage compared with short intervals (children: RR of scoring ≥ 2 on the skin damage scale 0.33, 95% CI 0.16 to 0.68; data for adults not pooled). PainTwo studies involving 193 participants measured pain. It is unclear if there is a difference between long and short interval dressing changes on pain during dressing removal (RR 0.80, 95% CI 0.46 to 1.38) (low quality evidence). AUTHORS' CONCLUSIONS: The best available evidence is currently inconclusive regarding whether longer intervals between CVAD dressing changes are associated with more or less catheter-related infection, mortality or pain than shorter intervals.

Sterile v aseptic non-touch technique for needle-less connector care on central venous access devices in a bone marrow transplant population: A comparative study.

PURPOSE: The aim of this study was to determine whether a variation in practice from an aseptic non-touch technique (ANTT) to a sterile technique when changing needleless connectors on central venous access devices (CVAD) was associated with any change in catheter related bloodstream infection (CRBSI) rates in the bone marrow transplant (BMT) population. METHODS: A two group comparative study without concurrent controls using a retrospective cohort was conducted in a large metropolitan hospital in Brisbane, Australia. INCLUSION CRITERIA: haematological malignancy, Hickman catheter inserted, age ≥18. A tool was developed to extract historical data from medical records and pathology results. PRIMARY OUTCOME: CRBSI. SECONDARY OUTCOMES: laboratory confirmed bloodstream infection, mucosal barrier injury laboratory confirmed bloodstream infection and skin contaminants. RESULTS: One hundred and fifty patients were assessed, 73/150 (49%) in the ANTT group. DEMOGRAPHICS: males 95/150 (63%), with 71/150 (47%) receiving an autologous BMT. No difference in CRBSI rates between groups was observed (ANTT n = 3 (4%) vs Sterile n = 1 (2.7%), p = 0.357 Fishers Exact Test). Infection by skin contaminants were identified in a similar number of cases across both groups (ANTT n = 9 (12.3%) vs Sterile n = 6 (7.8%)). CONCLUSIONS: No causal effect can be deduced from this small study; nevertheless results imply that an ANTT was not associated with increased CRBSI. Poor hand hygiene and ANTT were perceived across both groups. Quality and consistent ANTT is a safe method for managing intravascular devices, however education and awareness of pathogen transfer from healthcare worker and patient to their device is required.

Intravascular device administration sets: replacement after standard versus prolonged use in hospitalised patients-a study protocol for a randomised controlled trial (The RSVP Trial).

INTRODUCTION: Vascular access devices (VADs), such as peripheral or central venous catheters, are vital across all medical and surgical specialties. To allow therapy or haemodynamic monitoring, VADs frequently require administration sets (AS) composed of infusion tubing, fluid containers, pressure-monitoring transducers and/or burettes. While VADs are replaced only when necessary, AS are routinely replaced every 3-4 days in the belief that this reduces infectious complications. Strong evidence supports AS use up to 4 days, but there is less evidence for AS use beyond 4 days. AS replacement twice weekly increases hospital costs and workload. METHODS AND ANALYSIS: This is a pragmatic, multicentre, randomised controlled trial (RCT) of equivalence design comparing AS replacement at 4 (control) versus 7 (experimental) days. Randomisation is stratified by site and device, centrally allocated and concealed until enrolment. 6554 adult/paediatric patients with a central venous catheter, peripherally inserted central catheter or peripheral arterial catheter will be enrolled over 4 years. The primary outcome is VAD-related bloodstream infection (BSI) and secondary outcomes are VAD colonisation, AS colonisation, all-cause BSI, all-cause mortality, number of AS per patient, VAD time in situ and costs. Relative incidence rates of VAD-BSI per 100 devices and hazard rates per 1000 device days (95% CIs) will summarise the impact of 7-day relative to 4-day AS use and test equivalence. Kaplan-Meier survival curves (with log rank Mantel-Cox test) will compare VAD-BSI over time. Appropriate parametric or non-parametric techniques will be used to compare secondary end points. p Values of <0.05 will be considered significant. ETHICS AND DISSEMINATION: Relevant ethical approvals have been received. CONSORT Statement recommendations will be used to guide preparation of any publication. Results will be presented at relevant conferences and sent to the major organisations with clinical practice guidelines for VAD care.

Exploring palliative care provision for recipients of allogeneic hematopoietic stem cell transplantation who relapsed.

PURPOSE/OBJECTIVES: To quantify the characteristics of patients who die in the hospital from relapse after allogeneic hematopoietic stem cell transplantation (alloHSCT), explore palliative care integration and end-of-life (EOL) care, and benchmark standards of care. DESIGN: Retrospective chart review cohort study; a cross-sectional survey design guided a national survey. SETTING: A chart review was conducted in a large tertiary hospital in Australia. The survey was distributed to leading alloHSCT centers in Australia and New Zealand. SAMPLE: The chart review sample group was patients in the hematology department who had received an alloHSCT, relapsed, and died in the hospital (N = 40). The survey sample group was the most advanced nurse involved in patient care at each facility (N = 14). METHODS: A quantitative data collection tool created for chart review, as well as patient notes written by the physician, were examined. The quantitative data collection tool was created for the survey, which was conducted via email or telephone. MAIN RESEARCH VARIABLES: The chart review measured patient demographics, palliative care integration, EOL care, and symptoms. Survey topics included services available, referrals to palliative care services, EOL discussions, and symptom management. FINDINGS: About half of the patients were seen by the palliative care service. Many patients experienced severe symptoms in the terminal phase. Survey participants felt EOL discussions were left until the terminal phase. Participants believed early palliative care integration was beneficial for patients and their family. CONCLUSIONS: The chart review demonstrated late integration of palliative care and poor standards of EOL care. Survey results reiterated this and reflected that nurses are supportive of earlier integration of palliative care and improving EOL care. IMPLICATIONS FOR NURSING: Palliative care should be integrated earlier, and nursing roles have the potential to address unmet needs for these patients.
