Trajectory of Sleep, Depression, and Quality of Life in Pediatric HSCT Recipients.

Disrupted sleep is commonly reported during hematopoietic stem cell transplant. In this study, we use actigraphy to measure sleep parameters, and qualitative measures of quality of life, depression, and sleep in pediatric and young adult transplant recipients to describe their time course through transplant. Eight patients had evaluable actigraphy data, and 10 patients completed the surveys. The median age of the 6 male and 7 female participants was 13.94 years old. Sleep duration and efficiency measured by actigraphy were suboptimal prior to transplant, then declined to a nadir between Day +7 to +14. Self-reported sleep quality, depression, and quality of life were worst at Day +14 to +30 but improved by Day +100. Findings support efforts to improve sleep, which may improve recovery, mental health and quality of life.

Quality Improvement in Hematopoietic Stem Cell Transplant and Cellular Therapy: Using the Model for Improvement to impact Outcomes.

Quality improvement and quality assurance form a complementary and independent relationship. Quality assurance measures compliance against industry standards using audits, whereas quality improvement is a continuous process focused on processes and systems that can improve care. The Model for Improvement is a robust quality improvement tool that transplant and cellular therapy teams can use to redesign healthcare processes. The Model for Improvement uses several components addressed in sequence to organize and critically evaluate improvement activities. Unlike other health sciences clinical research, quality improvement projects, and research are based on dynamic hypotheses that develop into observable, serial tests of change with continuous collection and feedback of performance data to stakeholders.

Outcomes after bloodstream infection in hospitalized pediatric hematology/oncology and stem cell transplant patients.

BACKGROUND: Pediatric hematology/oncology (PHO) patients receiving therapy or undergoing hematopoietic stem cell transplantation (HSCT) often require a central line and are at risk for bloodstream infections (BSI). There are limited data describing outcomes of BSI in PHO and HSCT patients. METHODS: This is a multicenter (n = 17) retrospective analysis of outcomes of patients who developed a BSI. Centers involved participated in a quality improvement collaborative referred to as the Childhood Cancer and Blood Disorder Network within the Children's Hospital Association. The main outcome measures were all-cause mortality at 3, 10, and 30 days after positive culture date; transfer to the intensive care unit (ICU) within 48 hours of positive culture; and central line removal within seven days of the positive blood culture. RESULTS: Nine hundred fifty-seven BSI were included in the analysis. Three hundred fifty-four BSI (37%) were associated with at least one adverse outcome. All-cause mortality was 1% (n = 9), 3% (n = 26), and 6% (n = 57) at 3, 10, and 30 days after BSI, respectively. In the 165 BSI (17%) associated with admission to the ICU, the median ICU stay was four days (IQR 2-10). Twenty-one percent of all infections (n = 203) were associated with central line removal within seven days of positive blood culture. CONCLUSIONS: BSI in PHO and HSCT patients are associated with adverse outcomes. These data will assist in defining the impact of BSI in this population and demonstrate the need for quality improvement and research efforts to decrease them.

Healthcare Burden, Risk Factors, and Outcomes of Mucosal Barrier Injury Laboratory-Confirmed Bloodstream Infections after Stem Cell Transplantation.

Mucosal barrier injury laboratory-confirmed bloodstream infections (MBI-LCBIs) lead to significant morbidity, mortality, and healthcare resource utilization in hematopoietic stem cell transplant (HSCT) patients. Determination of the healthcare burden of MBI-LCBIs and identification of patients at risk of MBI-LCBIs will allow researchers to identify strategies to reduce MBI-LCBI rates. The objective of our study was to describe the incidence, risk factors, timing, and outcomes of MBI-LCBIs in hematopoietic stem cell transplant patients. We performed a retrospective analysis of 374 patients who underwent HSCT at a large free-standing academic children's hospital to determine the incidence, risk factors, and outcomes of patients that developed a bloodstream infection (BSI) including MBI-LCBI, central line-associated BSI (CLABSI), or secondary BSI in the first year after HSCT. Outcome measures included nonrelapse mortality (NRM), central venous catheter removal within 7 days of positive culture, shock, admission to the pediatric intensive care unit (PICU) within 48 hours of positive culture, and death within 10 days of positive culture. One hundred seventy BSIs were diagnosed in 100 patients (27%): 80 (47%) MBI-LCBIs, 68 (40%) CLABSIs, and 22 (13%) secondary infections. MBI-LCBIs were diagnosed at a significantly higher rate in allogeneic HSCT patients (18% versus 7%, P = .007). Reduced-intensity conditioning (OR, 1.96; P = .015) and transplant-associated thrombotic microangiopathy (OR, 2.94; P = .0004) were associated with MBI-LCBI. Nearly 50% of all patients with a BSI developed septic shock, 10% died within 10 days of positive culture, and nearly 25% were transferred to the PICU. One-year NRM was significantly increased in patients with 1 (34%) and more than 1 (56%) BSIs in the first year post-HSCT compared with those who did not develop BSIs (14%) (P ≤ .0001). There was increased 1-year NRM in patients with at least 1 MBI-LCBI (OR, 1.94; P = .018) and at least 1 secondary BSI (OR, 2.87; P = .0023) but not CLABSIs (OR, 1.17; P = .68). Our data demonstrate that MBI-LCBIs lead to substantial use of healthcare resources and are associated with significant morbidity and mortality. Reduction in frequency of MBI-LCBI should be a major public health and scientific priority.

Sustained reductions in time to antibiotic delivery in febrile immunocompromised children: results of a quality improvement collaborative.

BACKGROUND: Timely delivery of antibiotics to febrile immunocompromised (F&I) paediatric patients in the emergency department (ED) and outpatient clinic reduces morbidity and mortality. OBJECTIVE: The aim of this quality improvement initiative was to increase the percentage of F&I patients who received antibiotics within goal in the clinic and ED from 25% to 90%. METHODS: Using the Model of Improvement, we performed Plan-Do-Study-Act cycles to design, test and implement high-reliability interventions to decrease time to antibiotics. Pre-arrival interventions were tested and implemented, followed by post-arrival interventions in the ED. Many processes were spread successfully to the outpatient clinic. The Chronic Care Model was used, in addition to active family engagement, to inform and improve processes. RESULTS: The study period was from January 2010 to January 2015. Pre-arrival planning improved our F&I time to antibiotics in the ED from 137 to 88 min. This was sustained until October 2012, when further interventions including a pre-arrival huddle decreased the median time to <50 min. Implementation of the various processes to the clinic delivery system increased the mean percentage of patients receiving antibiotics within 60 min to >90%. In September 2014, we implemented a rapid response team to improve reliable venous access in the ED, which increased our mean percentage of patients receiving timely antibiotics to its highest rate (95%). CONCLUSIONS: This stepwise approach with pre-arrival planning using the Chronic Care Model, followed by standardisation of processes, created a sustainable improvement of timely antibiotic delivery in F&I patients.

Rapid cycle development of a multifactorial intervention achieved sustained reductions in central line-associated bloodstream infections in haematology oncology units at a children's hospital: a time series analysis.

BACKGROUND: Immunocompromised children are at high risk for central line-associated bloodstream infections (CLABSIs) and its associated morbidity and mortality. Prevention of CLABSIs depends on highly reliable care. PURPOSE: Since the summer of 2013, we saw an increase in patient volume and acuity in our centre. Additionally, CLABSIs rates more than tripled during this period. The purpose of this initiative was to rapidly identify and mitigate potential underlying drivers to the increased CLABSI rate. METHODS: Through small tests of change, we implemented a standard process for daily hygiene; increased awareness of high-risk patients with CLABSI; improved education/assistance for nurses performing high-risk central venous catheter procedures; and developed a system to improve allocation of resources to de-escalate system stress. RESULTS: The CLABSI rate from June 2013 to May 2014 was 2.03 CLABSIs/1000 line days. After implementation of our interventions, we saw a significant decrease in the CLABSI rate to 0.39 CLABSIs/1000 line days (p=0.008). Key processes have become more reliable: 100% of dressing changes are completed with the new two-person standard; daily hygiene adherence has increased from 25% to 70%; 100% of nurses are approached daily by senior nursing for assistance with high-risk procedures; and patients at risk for a CLABSI are identified daily. CONCLUSIONS: Stress to a complex system caring for high-risk patients can challenge CLABSI rates. Identifying key processes and executing them reliably can stabilise outcomes during times of system stress.

An unexpected increase in catheter-associated bloodstream infections at a children's hospital following introduction of the Spiros closed male connector.

BACKGROUND: Catheter-associated bloodstream infections (CA-BSIs) are associated with increased morbidity and mortality. Previous investigations have reported outbreaks of CA-BSI temporally associated with the use of needleless connector valves or similar devices. METHODS: We observed an unexpected increase in the rate of CA-BSI at our institution during August 2009. We used statistical process control and quality improvement methodology to identify the factor(s) associated with this increased rate of CA-BSI. RESULTS: We reviewed the overall hospital Shewhart U chart for CA-BSI, which indicated special cause variation with an unexpected cluster (6/9; 67%) of CA-BSIs localized to the oncology ward and the bone marrow transplant unit. An event-cause analysis review showed that 5 of these 9 infections were caused by Staphylococcus aureus. We discovered that the Spiros Closed Male Connector (ICU Medical, San Clemente, CA) had been introduced in these 2 units around the same time as the cluster of infections occurred. Based on this information, we discontinued the use of this device, and the CA-BSI rate and distribution of causative microorganisms returned to previous baseline values. CONCLUSION: This case study highlights the utility of statistical process control in the surveillance and investigation of CA-BSI.

A hospital-wide quality-improvement collaborative to reduce catheter-associated bloodstream infections.

BACKGROUND: Catheter-associated bloodstream infections (CA BSIs) are associated with increased hospital length of stay, total hospital costs, and mortality. Quality-improvement collaboratives (QICs) are frequently used to improve health care quality. Our PICU was previously involved in a successful national QIC to reduce the incidence of CA BSI in critically ill children. OBJECTIVE: We hypothesized that the formation of a hospital-wide QIC would reduce the incidence of CA BSI throughout our institution. METHODS: We retrospectively reviewed the incidence of CA BSI from March 2006 to March 2010. The collaborative approach included hospital-wide implementation of central-line insertion and maintenance bundles that emphasized full sterile barrier precautions and chlorhexidine skin preparation during line insertion, daily discussion of catheter necessity, and meticulous site and tubing care. The hospital units involved were our 3 critical care units, the oncology unit, the bone marrow transplant unit, and wards. Each individual unit was responsible for collecting unit-specific data and performing event-cause analysis within 48 hours of identifying a CA BSI. These results were shared with the other hospital units during monthly meetings. Compliance with the insertion and maintenance bundles was monitored and reported to each unit monthly. RESULTS: The hospital-wide CA-BSI rate decreased from a baseline of 3.0 to <1.0 CA BSI per 1000 line-days after implementation of the QIC. CONCLUSIONS: Our hospital-wide QIC resulted in a significant reduction in the incidence of CA BSI at our children's hospital. A collaborative model based on improvement science methodology is both feasible and effective in reducing the incidence of CA BSI.
