Reducing ambulatory central line-associated bloodstream infections: A family-centered approach.

BACKGROUND: Ambulatory central line-associated bloodstream infections (CLABSIs) cause significant morbidity and mortality, especially in pediatric oncology. Few studies have had interventions directed toward caregivers managing central lines (CL) at home to reduce ambulatory CLABSI rates. We aimed to reduce and sustain our ambulatory CLABSI rate by 25% within 3 years of the start of a quality improvement intervention. PROCEDURE: Plan-do-study-act cycles were implemented beginning April 2016. The main intervention was a family-centered CL care skill development curriculum for external CLs. Training began upon hospital CL insertion, followed by an ambulatory teach-back program to achieve home caregiver CL care independence. Other changes included: standardizing ambulatory nurse CL care practice (audits, a train the nurse trainer process, and workshops for independent home care agencies); developing aids for trainers and caregivers; providing supplies for clean surfaces; wide dissemination of the program; and minimizing opportunities of CLABSI (e.g., standardizing timing of CL removal). The outcome measure was the ambulatory CLABSI rate (excluding mucosal barrier injury laboratory-confirmed bloodstream infection), compared pre intervention (January 2015 to March 2016) to post intervention, including 2 years of sustainability (April 2016 to June 2023), using statistical process control charts. We estimated the total number of CLABSI and associated healthcare charges prevented. RESULTS: The ambulatory CLABSI rate decreased by 52% from 0.25 to 0.12 per 1000 CL days post intervention, achieved within 27 months; 117 CLABSI were prevented, with $4.2 million hospital charges and 702 hospital days avoided. CONCLUSIONS: Focusing efforts on home caregivers CL care may lead to reduction in pediatric oncology ambulatory CLABSI rates.

Microbiology and risk factors for central line-associated bloodstream infections among pediatric oncology outpatients: a single institution experience of 41 cases.

BACKGROUND: Risk factors for central line-associated bloodstream infections (CLABSI) among children with cancer in the outpatient setting remain poorly defined, and the microbiology may differ from hospital-onset CLABSI. MATERIALS AND METHODS: We conducted a matched case-control study of oncology patients followed at the Dana Farber/Children's Hospital Cancer Center. Cases (N=41) were patients with CLABSI as per National Healthcare Safety Network criteria who had not been hospitalized in the preceding 48 hours. For each case we randomly selected 2 oncology outpatients with a central venous catheter and a clinic visit within 30 days of the case subject's CLABSI. Multivariate conditional logistic regression models were used to identify independent risk factors for CLABSI. We compared the microbiology to that of 54 hospital-onset CLABSI occurring at our institution during the study period. RESULTS: Independent predictors of community-onset CLABSI included neutropenia in the prior week (odds ratio 17.46; 95% confidence interval, 4.71-64.67) and tunneled externalized catheter (vs. implantable port; odds ratio 10.30; 95% confidence interval, 2.42-43.95). Nonenteric gram-negative bacteria were more frequently isolated from CLABSI occurring among outpatients. DISCUSSION: Pediatric oncology outpatients with recent neutropenia or tunneled externalized catheters are at increased risk of CLABSI. The microbiology of community-onset CLABSI differs from hospital-onset CLABSI.

Improving Home Caregiver Independence With Central Line Care for Pediatric Cancer Patients.

OBJECTIVE: Home caregivers (eg parents) of pediatric patients with cancer with external central lines (CL) must carefully maintain this device to prevent complications. No guidelines exist to support caregiver skill development, assess CL competency, follow-up after initial CL teaching, and support progress over time. We aimed to achieve >90% caregiver independence with CL care within 1 year through a family-centered quality improvement intervention. METHODS: Drivers to achieve CL care independence were identified using surveys and interviews of patient or caregivers, a multidisciplinary team with patient or family representatives, and piloting clinic return demonstrations (teach-backs). A family-centered CL care skill-learning curriculum, with a postdischarge teach-back program, was implemented using plan-do-study-act cycles. Patients or caregivers participated until independent with CL flushing. Changes included: language iterations to maximize patient or caregiver engagement, developing standardized tools for home use and for teaching and evaluating caregiver proficiency on the basis of number of nurse prompts required during the teach-back, earlier inpatient training, and clinic redesign to incorporate teach-backs into routine visits. The proportion of eligible patients whose caregiver had achieved independence in CL flushing was the outcome measure. Teach-back program participation was a process measure. Statistical process control charts tracked change over time. RESULTS: After 6 months of quality improvement intervention, >90% of eligible patients had a caregiver achieve independence with CL care. This was sustained for 30 months postintervention. Eighty-eight percent of patients (n = 181) had a caregiver participate in the teach-back program. CONCLUSION: A family-centered hands-on teach-back program can lead to caregiver independence in CL care.

Developing the Key Driver Diagram by Analyzing Home Central Line Caregiver Proficiency Factors.

Caregivers of pediatric oncology and stem cell transplant patients often care for central lines (CLs) at home. Methods to achieve caregiver CL care proficiency, and interventions designed with caregiver input are lacking. Methods: Caregivers of pediatric oncology and stem cell transplant patients patients with an external CL or removed within 2 weeks were eligible for a survey assessing knowledge, the value of training strategies, and comfort. We mapped responses (n = 79) and acceptability/challenges of introducing a pilot caregiver CL teach-back clinic program onto the capability, opportunity, motivation behavioral (COM-B) model of change to identify drivers of caregiver CL care proficiency. A working group, including caregivers, refined and approved a final driver diagram. Results: Survey: Ninety-four percent of caregivers answered knowledge questions correctly (capability); 95% considered hands-on training helpful (opportunity); 53% were not very comfortable with CL care (motivation). Teach-back: Seventy-nine percent of caregivers were interested in a teach-back as additional training; 38% participated (opportunity); 20% refused participation due to being overwhelmed/not having time (motivation). Thirty-three percent of participants had a CL proficiency assessment (capability). Drivers of home caregiver CL care proficiency included: support for the caregiver's physical capability to perform CL care; enabling the CL care nurse trainer role; facilitating and increasing training opportunities, and engaging caregivers early and continuously to motivate proficiency development appropriately. Conclusions: An approach centered on caregivers as main stakeholders can identify drivers to co-design an intervention for improved home CL care delivery. A standardized process to train and evaluate caregivers with multiple hands-on opportunities might be beneficial.

Three cases of first permanent molar extractions where extraction of the adjacent second deciduous molar is also indicated.

UNLABELLED: Appropriately timed extraction of a carious first permanent molar can result in favourable mesial drift of the second permanent molar when space is not required for orthodontic treatment. However, when the second deciduous molar adjacent to the extracted tooth is not removed, distal drift of the unerupted second premolar may occur. This paper discusses three patients who had first permanent molars extracted without removal of the adjacent second deciduous molar, encouraging unfavourable distal drift of the second premolar in the first two cases. Timely extraction of the second deciduous molar in the third case should prevent this orthodontic problem. CLINICAL RELEVANCE: Treatment of gross caries in a first permanent molar requires assessment of the patient's orthodontic status prior to treatment planning.

Central Venous Catheter Flushing Recommendations: A Systematic Evidence-Based Practice Review.

BACKGROUND: Treatment for many children with blood disorders or cancer includes the use of central venous catheters (CVCs). Few prospective studies have been conducted to address flushing guidelines in pediatric hematology oncology patients. Eighteen pediatric hematology oncology units were surveyed regarding current CVC flushing policies and procedures. Results reported extreme variations in CVC flush procedures, which instigated this systematic review. AIMS: The purpose of this project was to critically review current literature and expert opinion regarding CVC flushing practice in the hopes of reporting standardized recommendations. Dissemination of consistent recommendations may reduce practice variability and complications associated with CVCs as well as increase patient and family confidence and competence in providing CVC care. METHODS: Literature searches used PubMed, Medline, CINAHL, National Guidelines Clearinghouse, and Cochrane Database of Systematic Reviews. Multiple reviewers evaluated results relevant to CVC flushing procedures. Studies excluded were those that included neonates, peripheral intravenous catheters, dialysis catheters, and valved catheters. RESULTS: Evaluation of 5 randomized controlled trials, 3 observational studies, 2 systematic reviews, 7 guidelines, and 1 literature review using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) and Appraisal of Guidelines for Research & Evaluation II (AGREE II) tools, an overall low level of evidence, and weak recommendation for practice was concluded. CONCLUSION: Weak recommendation for daily flushing of noninfusing Broviac/Hickman catheters and accessed implanted ports may be made. There was not sufficient evidence for heparin volume or concentration recommendations. No recommendations can be reported for peripherally inserted central venous catheters. Further research is indicated for CVC flushing procedures in pediatric hematology oncology patients.

Impact of needleless connector change frequency on central line-associated bloodstream infection rate.

BACKGROUND: Bloodstream infection is the most common pediatric health care-associated infection and is strongly associated with catheter use. These infections greatly increase the cost of hospital stay. METHODS: To assess the association between needleless connector (NC) change frequency and central line-associated bloodstream infection (CLABSI) rate, we modeled monthly pediatric stem cell transplant (SCT) CLABSI rate in 3 periods: baseline period during which NC were changed every 96 hours regardless of infusate (period 1); trial period in which NC were changed every 24 hours with blood or lipid infusions (period 2); and a return to NC change every 96 hours regardless of infusate (period 3). Data on potential confounders were collected retrospectively. Autocorrelated segmented regression models were used to compare SCT CLABSI rates in each period, adjusting for potential confounders. CLABSI rates were also assessed for a nonequivalent control group (oncology unit) in which NC were changed every 24 hours with blood or lipid use in periods 2 and 3. RESULTS: SCT CLABSI rates were 0.41, 3.56, and 0.03 per 1,000 central line-days in periods 1, 2, and 3, respectively. In multivariable analysis, the CLABSI rate was significantly higher in period 2 compared with both period 1 (P = .01) and period 3 (P = .003). In contrast, CLABSI rates on the oncology unit were not significantly different among periods. CONCLUSION: In pediatric SCT patients, changing needleless connectors every 24 hours when blood or lipids are infused is associated with increased CLABSI rates. National recommendations regarding NC change frequency should be clarified.

Moving CLABSI prevention beyond the intensive care unit: risk factors in pediatric oncology patients.

BACKGROUND AND OBJECTIVE: Central line-associated bloodstream infections (CLABSIs) frequently complicate the use of central venous catheters (CVCs) among pediatric patients with cancer. Our objectives were to describe the microbiology and identify risk factors for hospital-onset CLABSI in this patient population. DESIGN: Retrospective case-control study. SETTING: Oncology and stem cell transplant units of a freestanding, 396-bed quaternary care pediatric hospital. PARTICIPANTS: Case subjects ([Formula: see text]) were patients with a diagnosis of malignancy and/or stem cell transplant recipients with CLABSI occurring during admission. Controls ([Formula: see text]) were identified using risk set sampling of hospitalizations among patients with a CVC, matched on date of admission. METHODS: Multivariate conditional logistic regression was used to identify independent predictors of CLABSI. RESULTS: The majority of CLABSI isolates were gram-positive bacteria (58%). The most frequently isolated organism was Enterococcus faecium, and 6 of 9 isolates were resistant to vancomycin. In multivariate analyses, independent risk factors for CLABSI included platelet transfusion within the prior week (odds ratio [OR], 10.90 [95% confidence interval (CI), 3.02-39.38]; [Formula: see text]) and CVC placement within the previous month (<1 week vs ≥1 month: OR, 11.71 [95% CI, 1.98-69.20]; [Formula: see text]; ≥1 week and <1 month vs ≥1 month: OR, 7.37 [95% CI, 1.85-29.36]; [Formula: see text]). CONCLUSIONS: Adjunctive measures to prevent CLABSI among pediatric oncology patients may be most beneficial in the month following CVC insertion and in patients requiring frequent platelet transfusions. Vancomycin-resistant enterococci may be an emerging cause of CLABSI in hospitalized pediatric oncology patients and are unlikely to be treated by typical empiric antimicrobial regimens.
