Repair of central venous access devices in intestinal failure patients is safe and cost-effective: A retrospective single centre cohort study.

INTRODUCTION: Patients with chronic intestinal failure (IF) require home parenteral nutrition (HPN). Central venous access is needed for prolonged use of PN, usually via a long term central venous access device (CVAD). Post insertion there may be mechanical complications with a CVAD such as catheter rupture or tear. Repair of damaged CVADs is possible to avoid risks associated with catheter replacement in patients with IF. However, catheter related blood stream infections (CRBSI) are a concern when CVAD's are accessed or manipulated. AIMS: To investigate the success of repair of CVADs in patients with IF on HPN, related to repair longevity and incidence of CRBSI following repair. METHOD: Nutrition team records of CVAD repairs carried out in patients with IF were reviewed retrospectively for the period April 2015 to March 2019. RESULTS: Nutrition Clinical Nurse Specialists carried out 38 repairs in 27 patients. Male n = 5, female n = 22; mean age 55 years. Catheter longevity before first repair (n = 27): median 851 days, IQR 137-1484 days. 30/38 (78.9%) of repairs were successful lasting ≥30days. Hospital admission was avoided in 76% of cases. 4 patients in the failed repair group underwent catheter re-insertion where 4 had a further, subsequently successful, repair, an overall success rate of 89.4% (34/38). 30-day CRBSI rate was 0.09/1000 catheter days in repaired catheters. In comparing costs, there is a potential cost saving of 2766GBP for repair compared to replacement of damaged CVADs. CONCLUSION: Repair of tunnelled CVADs in patients with IF is successful and safe with no increased risk of CRBSI. Significant cost savings may be made.

Antimicrobial-impregnated central venous catheters for preventing neonatal bloodstream infection: the PREVAIL RCT.

BACKGROUND: Clinical trials show that antimicrobial-impregnated central venous catheters reduce catheter-related bloodstream infection in adults and children receiving intensive care, but there is insufficient evidence for use in newborn babies. OBJECTIVES: The objectives were (1) to determine clinical effectiveness by conducting a randomised controlled trial comparing antimicrobial-impregnated peripherally inserted central venous catheters with standard peripherally inserted central venous catheters for reducing bloodstream or cerebrospinal fluid infections (referred to as bloodstream infections); (2) to conduct an economic evaluation of the costs, cost-effectiveness and value of conducting additional research; and (3) to conduct a generalisability analysis of trial findings to neonatal care in the NHS. DESIGN: Three separate studies were undertaken, each addressing one of the three objectives. (1) This was a multicentre, open-label, pragmatic randomised controlled trial; (2) an analysis was undertaken of hospital care costs, lifetime cost-effectiveness and value of information from an NHS perspective; and (3) this was a retrospective cohort study of bloodstream infection rates in neonatal units in England. SETTING: The randomised controlled trial was conducted in 18 neonatal intensive care units in England. PARTICIPANTS: Participants were babies who required a peripherally inserted central venous catheter (of 1 French gauge in size). INTERVENTIONS: The interventions were an antimicrobial-impregnated peripherally inserted central venous catheter (coated with rifampicin-miconazole) or a standard peripherally inserted central venous catheter, allocated randomly (1 : 1) using web randomisation. MAIN OUTCOME MEASURE: Study 1 - time to first bloodstream infection, sampled between 24 hours after randomisation and 48 hours after peripherally inserted central venous catheter removal. Study 2 - cost-effectiveness of the antimicrobial-impregnated peripherally inserted central venous catheter compared with the standard peripherally inserted central venous catheters. Study 3 - risk-adjusted bloodstream rates in the trial compared with those in neonatal units in England. For study 3, the data used were as follows: (1) case report forms and linked death registrations; (2) case report forms and linked death registrations linked to administrative health records with 6-month follow-up; and (3) neonatal health records linked to infection surveillance data. RESULTS: Study 1, clinical effectiveness - 861 babies were randomised (antimicrobial-impregnated peripherally inserted central venous catheter, n = 430; standard peripherally inserted central venous catheter, n = 431). Bloodstream infections occurred in 46 babies (10.7%) randomised to antimicrobial-impregnated peripherally inserted central venous catheters and in 44 (10.2%) babies randomised to standard peripherally inserted central venous catheters. No difference in time to bloodstream infection was detected (hazard ratio 1.11, 95% confidence interval 0.73 to 1.67; p = 0.63). Secondary outcomes of rifampicin resistance in positive blood/cerebrospinal fluid cultures, mortality, clinical outcomes at neonatal unit discharge and time to peripherally inserted central venous catheter removal were similar in both groups. Rifampicin resistance in positive peripherally inserted central venous catheter tip cultures was higher in the antimicrobial-impregnated peripherally inserted central venous catheter group (relative risk 3.51, 95% confidence interval 1.16 to 10.57; p = 0.02) than in the standard peripherally inserted central venous catheter group. Adverse events were similar in both groups. Study 2, economic evaluation - the mean cost of babies' hospital care was £83,473. Antimicrobial-impregnated peripherally inserted central venous catheters were not cost-effective. Given the increased price, compared with standard peripherally inserted central venous catheters, the minimum reduction in risk of bloodstream infection for antimicrobial-impregnated peripherally inserted central venous catheters to be cost-effective was 3% and 15% for babies born at 23-27 and 28-32 weeks' gestation, respectively. Study 3, generalisability analysis - risk-adjusted bloodstream infection rates per 1000 peripherally inserted central venous catheter days were similar among babies in the trial and in all neonatal units. Of all bloodstream infections in babies receiving intensive or high-dependency care in neonatal units, 46% occurred during peripherally inserted central venous catheter days. LIMITATIONS: The trial was open label as antimicrobial-impregnated and standard peripherally inserted central venous catheters are different colours. There was insufficient power to determine differences in rifampicin resistance. CONCLUSIONS: No evidence of benefit or harm was found of peripherally inserted central venous catheters impregnated with rifampicin-miconazole during neonatal care. Interventions with small effects on bloodstream infections could be cost-effective over a child's life course. Findings were generalisable to neonatal units in England. Future research should focus on other types of antimicrobial impregnation of peripherally inserted central venous catheters and alternative approaches for preventing bloodstream infections in neonatal care.

Babies who are born too early or who are very sick require intensive care after birth and during early life. Most will have a long, narrow, plastic tube, called a catheter, inserted into a vein. The catheter is used to give babies fluids containing medicines and nutrition to keep them well and help them grow. The catheter can remain in place for several days or weeks. But the presence of plastic tubing in the vein increases the risk of infection. This study aimed to find out whether or not catheters coated with antimicrobial medicines, called rifampicin and miconazole, could reduce the risk of infection. These medicines act by stopping germs from growing on the catheter, but do not harm the baby or interfere with other treatments. A randomised controlled trial was carried out in 18 neonatal units in England. Whenever a baby needed a catheter, their parents were asked for consent to participate in the trial. The baby was then randomised, similar to tossing a coin, to receive either the antimicrobial catheter or a standard one. A total of 861 babies participated. We followed up all babies in the same way until after the catheter was removed to compare how often babies in each group had an infection. It was found that antimicrobial catheters were no better or worse at preventing infection than standard catheters. Antimicrobial catheters cost more and we found no evidence of benefit; these results suggest that their use in neonatal intensive care is not justified. It was calculated that further research on ways to reduce infection may be good value for money, depending on the costs of this research. The babies who took part in this study were typical of babies in England receiving catheters, meaning that the results can be applied across the NHS. Future research should focus on catheters that contain other types of antimicrobials and alternative ways of preventing infection.

Device associated -health care associated infections monitoring, prevention and cost assessment at intensive care unit of University Hospital in Poland (2015-2017).

BACKGROUND: Device-associated health care-associated infections (DA-HAIs) in intensive care unit (ICU) patients constitute a major therapeutic issue complicating the regular hospitalisation process and having influence on patients' condition, length of hospitalisation, mortality and therapy cost. METHODS: The study involved all patients treated > 48 h at ICU of the Medical University Teaching Hospital (Poland) from 1.01.2015 to 31.12.2017. The study showed the surveillance and prevention of DA-HAIs on International Nosocomial Infection Control Consortium (INICC) Surveillance Online System (ISOS) 3 online platform according to methodology of the INICC multidimensional approach (IMA). RESULTS: During study period 252 HAIs were found in 1353 (549F/804M) patients and 14,700 patient-days of hospitalisation. The crude infections rate and incidence density of DA-HAIs was 18.69% and 17.49 ± 2.56 /1000 patient-days. Incidence density of ventilator-associated pneumonia (VAP), central line-associated bloodstream infection (CLA-BSI) and catheter-associated urinary tract infection (CA-UTI) per 1000 device-days were 12.63 ± 1.49, 1.83 ± 0.65 and 6.5 ± 1.2, respectively. VAP(137) constituted 54.4% of HAIs, whereas CA-UTI(91) 36%, CLA-BSI(24) 9.6%.The most common pathogens in VAP and CA-UTI was multidrug-resistant (MDR) Acinetobacter baumannii (57 and 31%), and methicillin-resistant Staphylococcus epidermidis (MRSE) in CLA-BSI (45%). MDR Gram negative bacteria (GNB) 159 were responsible for 63.09% of HAIs. The length of hospitalisation of patients with a single DA-HAI at ICU was 21(14-33) days, while without infections it was 6.0 (3-11) days; p = 0.0001. The mortality rates in the hospital-acquired infection group and no infection group were 26.1% vs 26.9%; p = 0.838; OR 0.9633;95% CI (0.6733-1.3782). Extra cost of therapy caused by one ICU acquired HAI was US$ 11,475/Euro 10,035. Hand hygiene standards compliance rate was 64.7%, while VAP, CLA-BSI bundles compliance ranges were 96.2-76.8 and 29-100, respectively. CONCLUSIONS: DA-HAIs was diagnosed at nearly 1/5 of patients. They were more frequent than in European Centre Disease Control report (except for CLA-BSI), more frequent than the USA CDC report, yet less frequent than in limited-resource countries (except for CA-UTI). They prolonged the hospitalisation period at ICU and generated substantial additional costs of treatment with no influence on mortality. The Acinetobacter baumannii MDR infections were the most problematic therapeutic issue. DA-HAIs preventive methods compliance rate needs improvement.

Costs of ambulatory pediatric healthcare-associated infections: Central-line-associated bloodstream infection (CLABSIs), catheter-associated urinary tract infection (CAUTIs), and surgical site infections (SSIs).

OBJECTIVE: Ambulatory healthcare-associated infections (HAIs) occur frequently in children and are associated with morbidity. Less is known about ambulatory HAI costs. This study estimated additional costs associated with pediatric ambulatory central-line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTI), and surgical site infections (SSIs) following ambulatory surgery. DESIGN: Retrospective case-control study. SETTING: Four academic medical centers. PATIENTS: Children aged 0-22 years seen between 2010 and 2015 and at risk for HAI as identified by electronic queries. METHODS: Chart review adjudicated HAIs. Charges were obtained for patients with HAIs and matched controls 30 days before HAI, on the day of, and 30 days after HAI. Charges were converted to costs and 2015 USD. Mixed-effects linear regression was used to estimate the difference-in-differences of HAI case versus control costs in 2 models: unrecorded charge values considered missing and a sensitivity analysis with unrecorded charge considered $0. RESULTS: Our search identified 177 patients with ambulatory CLABSIs, 53 with ambulatory CAUTIs, and 26 with SSIs following ambulatory surgery who were matched with 382, 110, and 75 controls, respectively. Additional cost associated with an ambulatory CLABSI was $5,684 (95% confidence interval [CI], $1,005-$10,362) and $6,502 (95% CI, $2,261-$10,744) in the 2 models; cost associated with a CAUTI was $6,660 (95% CI, $1,055, $12,145) and $2,661 (95% CI, -$431 to $5,753); cost associated with an SSI following ambulatory surgery at 1 institution only was $6,370 (95% CI, $4,022-$8,719). CONCLUSIONS: Ambulatory HAI in pediatric patients are associated with significant additional costs. Further work is needed to reduce ambulatory HAIs.

Optimizing Duration of Empiric Management of Suspected Central Line-Associated Bloodstream Infections in Pediatric Patients with Intestinal Failure.

OBJECTIVES: To assess whether a 24-hour length of hospitalization and empiric antibiotic therapy to exclude central line-associated bloodstream infection (CLABSI) in children with intestinal failure is potentially as safe as 48 hours, which is the duration most commonly used but not evidence based. STUDY DESIGN: A prospective single-institution observational cohort study was conducted among pediatric patients with intestinal failure from July 1, 2015, through June 30, 2018, to identify episodes of suspected CLABSI. The primary end point was time from blood sampling to positive blood culture. Secondary end points included presenting symptoms, laboratory test results, responses to a parent/legal guardian-completed symptom survey, length of inpatient stay, costs, and charges. RESULTS: Seventy-three patients with intestinal failure receiving nutritional support via central venous catheters enrolled; 35 were hospitalized with suspected CLABSI at least once during the study. There were 49 positive blood cultures confirming CLABSI in 128 episodes (38%). The median time from blood sampling to positive culture was 11.1 hours. The probability of a blood culture becoming positive after 24 hours was 2.3%. Elevated C-reactive protein and neutrophil predominance in white blood cell count were associated with positive blood cultures. Estimated cost savings by transitioning from a 48-hour to a 24-hour admission to rule-out CLABSI was $4639 per admission. CONCLUSIONS: A 24-hour duration of empiric management to exclude CLABSI may be appropriate for patients with negative blood cultures and no clinically concerning signs. A multi-institutional study would more robustly differentiate patients safe for discharge after 24 hours from those who warrant longer empiric treatment.

Preventing catheter-related infections in cancer patients: a review of current strategies.

Introduction: Central line-associated bloodstream infections (CLABSI) are a frequent cause of healthcare-associated infections, increasing healthcare costs and decreasing the quality of life for critically and chronically ill patients such as those with cancer. These infections are largely preventable and have been significantly reduced throughout the United States. However, further reduction of CLABSI requires continued innovation in preventive strategies.Areas covered: We provide an overview of the recent medical literature on catheter-related infections among cancer patients, discussing epidemiology, risk factors, and pathogenesis of CLABSI with a focus on the newest and current preventive measures. The data discussed here were retrieved mainly from clinical trials, meta-analyses, and systematic reviews published in the English language using a MEDLINE database search from 1 January 1990 until the end of December 2019.Expert opinion: The growing impact of CLABSI on the healthcare setting and mortality and morbidity rates in cancer patients calls for novel technologies for preventing central line-related infections. Advances in antimicrobial lock therapy are not limited to salvage therapy but have also provided a novel and promising prophylactic approach to CLABSI. Also, the use of antimicrobial-coated catheters with chlorhexidine-impregnated dressings, along with the application of insertion and maintenance bundles, is an effective and cost-effective approach for preventing central line-related infections.

Incidence, risk factors and healthcare costs of central line-associated nosocomial bloodstream infections in hematologic and oncologic patients.

Non-implanted central vascular catheters (CVC) are frequently required for therapy in hospitalized patients with hematological malignancies or solid tumors. However, CVCs may represent a source for bloodstream infections (central line-associated bloodstream infections, CLABSI) and, thus, may increase morbidity and mortality of these patients. A retrospective cohort study over 3 years was performed. Risk factors were determined and evaluated by a multivariable logistic regression analysis. Healthcare costs of CLABSI were analyzed in a matched case-control study. In total 610 patients got included with a CLABSI incidence of 10.6 cases per 1,000 CVC days. The use of more than one CVC per case, CVC insertion for conditioning for stem cell transplantation, acute myeloid leukemia, leukocytopenia (≤ 1000/µL), carbapenem therapy and pulmonary diseases were independent risk factors for CLABSI. Hospital costs directly attributed to the onset of CLABSI were 8,810 € per case. CLABSI had a significant impact on the overall healthcare costs. Knowledge about risk factors and infection control measures for CLABSI prevention is crucial for best clinical practice.

The impact of infection control cost reimbursement policy on central line-associated bloodstream infections.

BACKGROUND: In September 2016, the Korean National Health Insurance Service began reimbursing infection control (IC) costs on the condition that a certain number of doctors and full-time nurses for IC be allocated to supported hospitals. We analyzed the impact of the IC cost reimbursement policy on central line-associated bloodstream infections (CLABSIs). METHODS: A before-and-after study that analyzed the CLABSI rate trends between preintervention (January 2016 to February 2017) and intervention (March to December 2017) periods using autoregression time series analysis was performed in intensive care units (ICUs) at a 750-bed, secondary care hospital in Daegu, Republic of Korea. The enhanced IC team visited ICUs daily, monitored the implementation of CLABSI prevention bundles, and educated all personnel involved in catheter insertion and maintenance from March 2017. RESULTS: Autoregressive analysis revealed that the CLABSI rates per month in the preintervention and intervention periods were -0.256 (95% confidence interval, -0.613 to 0.101; P = .15) and -0.602 (95% confidence interval, -0.972 to -0.232; P = .008), respectively. The rates of compliance with maximal barrier precautions significantly improved from the preintervention (36.2%) to the intervention (77.9%) period (χ² test, P < .001). CONCLUSIONS: The IC cost reimbursement policy accelerated the decline in CLABSI rates significantly in monitored ICUs. A nationwide study to evaluate the effectiveness of the IC cost reimbursement policy for various health care-associated infections is warranted.

Cost-effectiveness of prophylactic antibiotic use to prevent catheter-associated urinary tract infections.

PURPOSE: We evaluate the cost-effectiveness of prophylactic antibiotic use to prevent catheter-associated urinary tract infections. MATERIALS AND METHODS: A decision tree model was used to assess the cost-effectiveness of prophylactic antibiotics in preventing catheter-associated urinary tract infections for patients with a short-term indwelling urinary catheter. The model accounted for incidence of urinary tract infections with and without the use of prophylactic antibiotics, incidence of antibiotic-resistant urinary tract infections, as well as costs associated with diagnosis and treatment of urinary tract infections and antibiotic-resistant urinary tract infections. Costs were calculated from the health care system's perspective. We conducted one-way sensitivity analyses. RESULTS: The base case analysis showed that the use of prophylactic antibiotics is cost-saving in preventing catheter-associated urinary tract infections. The use of prophylactic antibiotics resulted in lower costs and higher quality-adjusted life-years compared with no prophylactic antibiotics. Sensitivity analyses showed that the optimal strategy changes to no prophylactic antibiotics when the incidence of urinary tract infections after prophylactic antibiotics exceeds 22% or the incidence of developing urinary tract infections without prophylactic antibiotics is less than 12%. Varying the costs of prophylactic antibiotics, urinary tract infection treatment, or antibiotic-resistant urinary tract infection treatment within a reasonable range did not change the optimal strategy. CONCLUSIONS: Prophylactic antibiotic use to prevent catheter-associated urinary tract infections is cost-effective under most conditions. These results were sensitive to the likelihood of developing catheter-associated urinary tract infections with and without prophylactic antibiotics. Our results are limited to the cost-effectiveness perspective on this clinical practice.

You get back what you give: Decreased hospital infections with improvement in CHG bathing, a mathematical modeling and cost analysis.

BACKGROUND: Multiple studies have shown that bathing with chlorhexidine gluconate (CHG) wipes reduces hospital-acquired infections (HAIs). We employed a mathematical model to assess the impact of CHG patient bathing on central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), and hospital-onset Clostridium difficile (C diff) infections and the associated costs. METHODS: Using a Markov chain, we examined the effect of CHG bathing compliance on HAI outcomes and the associated costs. Using estimates from 2 different studies on CHG bathing effectiveness for CLABSI, CAUTI, and C diff, the number of HAIs per year were estimated along with associated costs. The simulations were conducted, assuming CHG bathing at varying compliance rates. RESULTS: At 32% reduction in HAI incidence, increasing CHG bathing compliance from 60% to 90% results in 20 averted infections and $815,301.75 saved cost. CONCLUSIONS: As CHG bathing compliance increases, yearly HAIs decrease, and the overall cost associated with the HAIs also decreases.

Epidemiology and health-economic burden of urinary-catheter-associated infection in English NHS hospitals: a probabilistic modelling study.

BACKGROUND: Catheter-associated urinary tract infection (CAUTI) and bloodstream infection (CABSI) are leading causes of healthcare-associated infection in England's National Health Service (NHS), but health-economic evidence to inform investment in prevention is lacking. AIMS: To quantify the health-economic burden and value of prevention of urinary-catheter-associated infection among adult inpatients admitted to NHS trusts in 2016/17. METHODS: A decision-analytic model was developed to estimate the annual prevalence of CAUTI and CABSI, and their associated excess health burdens [quality-adjusted life-years (QALYs)] and economic costs (£ 2017). Patient-level datasets and literature were synthesized to estimate population structure, model parameters and associated uncertainty. Health and economic benefits of catheter prevention were estimated. Scenario and probabilistic sensitivity analyses were conducted. FINDINGS: The model estimated 52,085 [95% uncertainty interval (UI) 42,967-61,360] CAUTIs and 7529 (UI 6857-8622) CABSIs, of which 38,084 (UI 30,236-46,541) and 2524 (UI 2319-2956) were hospital-onset infections, respectively. Catheter-associated infections incurred 45,717 (UI 18,115-74,662) excess bed-days, 1467 (UI 1337-1707) deaths and 10,471 (UI 4783-13,499) lost QALYs. Total direct hospital costs were estimated at £54.4M (UI £37.3-77.8M), with an additional £209.4M (UI £95.7-270.0M) in economic value of QALYs lost assuming a willingness-to-pay threshold of £20,000/QALY. Respectively, CABSI accounted for 47% (UI 32-67%) and 97% (UI 93-98%) of direct costs and QALYs lost. Every catheter prevented could save £30 (UI £20-44) in direct hospital costs and £112 (UI £52-146) in QALY value. CONCLUSIONS: Hospital catheter prevention is poised to reap substantial health-economic gains, but community-oriented interventions are needed to target the large burden imposed by community-onset infection.

Patterns of Health Care Costs Due to External Ventricular Drain Infections.

BACKGROUND: External ventricular drain (EVD) infections are a significant cause of morbidity among neurosurgical patients and have been correlated with increased length of hospital stay and longer requirements for intensive care. To date, no studies have examined the financial impact of EVD infections. METHODS: Patients who underwent EVD placement between December 2010 and January 2016 were included in the study. Clinical records were retrospectively reviewed and health care cost data were obtained from the hospital's finance department. Clinical information included patient demographics, details from the hospital course, and outcomes. Total costs, direct/indirect, and fixed/variable costs were analyzed for every patient. RESULTS: Over the 5-year study period, 246 EVDs were placed in 243 patients with an overall infection rate of 9.9% (N = 24). The median EVD duration for infected versus noninfected patients was 19 and 9 days, respectively (P < 0.0001). Median length of intensive care unit stay also was increased for patients with EVD infection (30 days vs. 13 days, P < 0.0001). Total health care costs were significantly greater for infected patients (US$ 168,692 vs. US$ 83,919, P < 0.0001). This trend was comparable for all other cost subtypes, including fixed-direct costs, fixed-indirect costs, variable direct costs, and variable-indirect costs. CONCLUSIONS: EVD infection has a substantial effect on clinical morbidity and healthcare costs. These results demonstrate the imperative need to improve EVD infection prevention, particularly in the setting of a value-based health care system.

[Cost analysis of haemodialysis catheter related bloodstream infection through the DRG system, "on behalf of Project Group of Vascular Access of Italian Society of Nephrology"].

Catheter related bloodstream infections (CRBSI) represent a complication that often requires hospitalization and the use of economic resources. In Italy, there is no literature that considers the costs of CRBSI for tunneled catheters (CVCt). The aim of this work is to evaluate the relative costs of CRBSI through the DRG system. From 2012 to 2017 we examined 2.257 hospital discharge forms, 358 of which relating to haemodialysis patients. Patients with CVCt (167), compared to FAVs (157), on average stay in hospital longer (10 vs. 8 days), entail higher costs (+8.5%) and higher admissions rate for infections (+114%). The incidence of CRBSI was 0.67 episodes per 1000 CVCt/days. CRBSI accounts for 23% of the cases of hospitalization of patients with CVCt and 5.2% of total hospitalization costs. Complicated CRBSI involve a 9% increase in average costs compared to simple ones, with patients staying in hospital three times longer. The cost of a CRBSI varies from €4,080 up to €14,800, with an average cost of €5,575. The costs calculated here are less than a third of that reported in American literature but this can be explained by the different reimbursement rates systems. The methodology of CRBSI costs through DRGs appears simple, and its main limit is the correct compilation of the discharge form. This is a reminder that discharge forms are an integral part of the medical record and can become important in recognizing the cost of the medical services provided.

Attributable length of stay and cost for pediatric and neonatal central line-associated bloodstream infections in Greece.

BACKGROUND AND OBJECTIVE: Central line-associated bloodstream infections (CLABSIs) are the most frequent pediatric hospital-acquired infections and are associated with significant morbidity and healthcare costs. The aim of our study was to determine the attributable length of stay (LOS) and cost for CLABSIs in pediatric patients in Greece, for which there is currently a paucity of data. METHODS: A retrospective matched-cohort study was performed in two tertiary pediatric hospitals. Inpatients with a central line in neonatal and pediatric intensive care units, hematology/oncology units, and a bone marrow transplantation unit between June 2012 and June 2015 were eligible. Patients with confirmed CLABSI were enrolled on the day of the event and were matched (1:1) to patients without CLABSI (non-CLABSIs) by hospital, unit, and LOS prior to study enrollment (188 children enrolled, 94 CLABSIs). The primary outcome measure was the attributable LOS and cost. Baseline demographic and clinical characteristics were recorded. Attributable outcomes were calculated as the differences in estimates of outcomes between CLABSIs and non-CLABSIs, after adjustment for propensity score and potential confounders. RESULTS: There were no differences between the two groups regarding their baseline characteristics. After adjustment for age, gender, matching characteristics, central line management after study enrollment, and propensity score, the mean LOS and cost were 57.5days and €31,302 in CLABSIs versus 36.6days and €17,788 in non-CLABSIs. Overall, a CLABSI was associated with a mean (95% CI) adjusted attributable LOS and cost of 21days (7.3-34.8) and €13,727 (5,758-21,695), respectively. No significant difference was detected in LOS and cost by hospitalization unit. CONCLUSIONS: CLABSIs were found to impose a significant economic burden in Greece, a finding that highlights the importance of implementing CLABSI prevention strategies.

Risk-Set Matching to Assess the Impact of Hospital-Acquired Bloodstream Infections.

Hospital-acquired bloodstream infections have a definite impact on patient encounters and cause increased length of stay, costs, and mortality. However, methods for estimating these effects are potentially biased, especially if the time of infection is not incorporated into the estimation strategy. We focused on matching patient encounters in which a hospital-acquired infection occurred to comparable encounters in which an infection did not occur. This matching strategy is susceptible to a selection bias because inpatients that stay longer in the hospital are more likely to acquire an infection and thus also are more likely to have longer and more costly stays. Instead, we have proposed risk-set matching, which matches infected encounters to similar encounters still at risk for infection at the corresponding time of infection. Matching on the one-dimensional propensity score can create comparable pairs for a large number of characteristics; an analogous propensity score is described for risk-set matching. We have presented dramatically different estimates using these 2 approaches with data from a pediatric cohort from the Premier Healthcare Database, United States, 2009-2016. The results suggest that estimates that did not incorporate time of infection exaggerated the impact of hospital-acquired infections with regard to attributed length of stay and costs.

The Cost-effectiveness of Antimicrobial Lock Solutions for the Prevention of Central Line-Associated Bloodstream Infections.

Background: Antimicrobial lock solutions are a low-cost strategy that can reduce the incidence of central line-associated bloodstream infection (CLABSI). The aim of this study was to evaluate the cost-effectiveness of antimicrobial locks for the prevention of CLABSI. Methods: We constructed a decision-analytic model comparing antimicrobial lock solutions to heparin locks for the prevention of CLABSI in 3 settings: hemodialysis, cancer treatment, and home parenteral nutrition. Cost-effectiveness was determined by calculating CLABSIs prevented and incremental cost-effectiveness ratios. Uncertainty was addressed by plotting cost-effectiveness planes and acceptability curves for various willingness-to-pay thresholds. Results: In probabilistic analysis, at a willingness to pay of $50000, antimicrobial lock solutions had a 96.24% chance of being cost-effective, compared with heparin locks in the hemodialysis setting, an 88.00% chance in the cancer treatment setting, and a 92.73% chance in the home parenteral nutrition setting. In base-case analysis, antimicrobial lock solutions resulted in savings of $68721.03 for the hemodialysis setting, $85061.41 for the cancer setting, and $78513.83 for the home parenteral nutrition setting per CLABSI episode prevented. Conclusions: In 3 distinct and clinically important settings (hemodialysis, cancer treatment, and home parenteral nutrition), antimicrobial lock solutions are an effective strategy for the prevention of CLABSI, and their use can result in significant healthcare savings.

Study on the cost attributable to central venous catheter-related bloodstream infection and its influencing factors in a tertiary hospital in China.

BACKGROUND: Central venous catheters (CVC) have been widely used for patients with severe conditions. However, they increase the risk of catheter-related bloodstream infection (CRBSI), which is associated with high economic burden. Until now, no study has focused on the cost attributable to CRBSI in China, and data on its economic burden are unavailable. The aim of this study was to assess the cost attributable to CRBSI and its influencing factors. METHODS: A retrospective matched case-control study and multivariate analysis were conducted in a tertiary hospital, with 94 patients (age ≥ 18 years old) from January 2011 to November 2015. Patients with CRBSI were matched to those without CRBSI by age, principal diagnosis, and history of surgery. The difference in cost between the case group and control group during the hospitalization was calculated as the cost attributable to CRBSI, which included the total cost and five specific cost categories: drug, diagnostic imaging, laboratory testing, health care technical services, and medical material. The relation between the total cost attributable to CRBSI and its influencing factors such as demographic characteristics, diagnosis and treatment, and pathogenic microorganism, was analysed with a general linear model (GLM). RESULTS: The total cost attributable to CRBSI was $3528.6, and the costs of specific categories including drugs, diagnostic imaging, laboratory testing, health care technical services, and medical material, were $2556.4, $112.1, $321.7, $268.7, $276.5, respectively. GLM analysis indicated that the total cost was associated with the intensive care unit (ICU), pathogenic microorganism, age, and catheter number, according to the sequence of standardized estimate (ß). ICU contributed the most to the model R-square. CONCLUSION: Central venous catheter-related bloodstream infection represents a great economic burden for patients. More attentions should be paid to further prevent and control this infection in China.

Incidents related to the Hickman® catheter: identification of damages.

OBJECTIVE: to identify damages resulting from incidents with the Hickman® catheter. METHOD: descriptive, retrospective, qualitative approach. The source of data were the notifications of incidents that occurred between January 2012 and May 2015, as well as the information available on the medical records of patients involved in incidents with the Hickman® catheter. RESULTS: the incidents related to the Hickman® catheter with the greatest impact on patient care were obstruction, fracture and traction. All incidents caused damage to patients, in a greater or lesser degree, in the dimensions of physical damage and subjective damage. FINAL CONSIDERATIONS: damage or potential risk of damage was present in all incidents analyzed. The need to revise cleaning and obstruction protocols for the maintenance of the permeability of Hickman® catheters was demonstrated.

Clinical and economic impact of the taurolidine lock on home parenteral nutrition.

INTRODUCTION: catheter-related bloodstream infections (CRBSI) are one of the most serious concerns in patients on home parenteral nutrition (HPN) which involve high morbidity and cost for the healthcare system. In the last years, taurolidine lock has proven to be beneficial in the prevention of CRBSI; however, the evidence of its efficiency is limited. OBJECTIVE: to determine if taurolidine lock is a cost-effective intervention in patients on HPN. MATERIALS AND METHODS: retrospective study in patients on HPN with taurolidine lock. We compared the CRBSI rate and cost of its complications before and during taurolidine lock. RESULTS: thirteen patients, six (46%) males and seven (54%) females, with a mean age of 61.08 (SD = 14.18) years received taurolidine lock. The total days of catheterization pre and per-taurolidine were 12,186 and 5,293, respectively. The underlying disease was benign in five patients (38.5%) and malignant in eight (61.5%). The CRBSI rate pre vs per-taurolidine was 3.12 vs 0.76 episodes per 1,000 catheter days (p = 0.0058). When the indication was a high CRBSI rate, this was 9.72 vs 0.39 (p < 0.001) in pre and per-taurolidine period respectively. No differences have been observed in the occlusion rates. None of the patients reported any adverse effects. The total cost of CRBSI in the pre-taurolidine period was 151,264.14 euros vs 24,331.19 euros in the per-taurolidine period. CONCLUSIONS: our study shows that taurolidine lock is a cost-effective intervention in patients on HPN with high risk of CRBSI.
