Financial consequences of hospital-acquired bacteraemia in three Belgian hospitals in 2003 and 2004

Excess length of stay and readmission following hospital-acquired bacteraemia: a population-based cohort study applying a multi-state model approach

OBJECTIVES

Population-based estimates of excess length of stay after hospital-acquired bacteraemia (HAB) are few and prone to time-dependent bias. We investigated the excess length of stay and readmission after HAB.

METHODS

This population-based cohort study included the North Denmark Region adult population hospitalized for ≥48 hours, from 2006 to 2018. Using a multi-state model with 45 days of follow-up, we estimated adjusted hazard ratios (aHRs) for end of stay and discharge alive. The excess length of stay was defined as the difference in residual length of stay between infected and uninfected patients, estimated using a non-parametric approach with HAB as time-dependent exposure. Confounder effects were estimated using pseudo-value regression. Readmission after HAB was investigated using the Cox regression.

RESULTS

We identified 3457 episodes of HAB in 484 291 admissions in 205 962 unique patients. Following HAB, excess length of stay was 6.6 days (95% CI, 6.2-7.1 days) compared with patients at risk. HAB was associated with decreased probability of end of hospital stay (aHR, 0.60; 95% CI, 0.57-0.62) driven by the decreased hazard for discharge alive; the aHRs ranged from 0.30 (95% CI, 0.23-0.40) for bacteraemia stemming from 'heart and vascular' source to 0.72 (95% CI, 0.69-0.82) for the 'urinary tract'. Despite increased post-discharge mortality (aHR, 2.76; 95% CI, 2.38-3.21), HAB was associated with readmission (aHR, 1.42; 95% CI, 1.31-1.53).

CONCLUSION

HAB was associated with considerably excess length of hospital stay compared with hospitalized patients without bacteraemia. Among patients discharged alive, HAB was associated with increased readmission rates.

The Association Between Hospital Financial Performance and the Quality of Care - A Scoping Literature Review

BACKGROUND

Improving the quality of hospital care is an important policy objective. Hospitals operate under pressure to contain costs and might face challenges related to financial deficits. The objective of this paper was to identify and map the available evidence on the association between hospital financial performance (FP) and quality of care (Q).

METHODS

A scoping review was performed. Searches were conducted in 7 databases: Medline via PubMed, EMBASE, Web of Science, Scopus, EconLit, ABI/INFORM, and Business Source Complete. The search strategy combined multiple terms from 3 topics: hospital AND FP AND Q. The collected data were analysed using both quantitative and qualitative methods.

RESULTS

10 503 records were screened and 151 full text papers analysed. A total of 69 papers were included (60 empirical, 2 theoretical, 5 literature reviews, and 2 dissertations). The majority of identified studies were published within the last decade (2010-2021). Most empirical studies had been conducted in the United States (55/60), used cross-sectional approaches (32/60) and applied diverse regression models with FP measures as dependent variables, thus measuring the impact of Q on hospitals FP (34/60). The comparability of the studies' results is limited due to differences in applied methods and settings. Yet, the general overview shows that in almost half of the cases the association between hospital FP and Q was positive, while no study showed a clear negative association.

CONCLUSION

This scoping review provides an overview of the available literature on the association between hospital FP and Q. The results highlight numerous research gaps: (1) systematic reviews and meta-analyses of existing studies with similar measures of FP and Q are unavailable, (2) further methodological/conceptual work is needed on the metrics measuring hospital FP and Q, and (3) more empirical studies should analyse the association between FP and Q in non-US healthcare settings.

Real-world use of procalcitonin and other biomarkers among sepsis hospitalizations in the United States: A retrospective, observational study

Background

Sepsis management guidelines endorse use of biomarkers to support clinical assessment and treatment decisions in septic patients. The impact of biomarkers on improving patient outcomes remains uncertain.

Methods

Retrospective observational study of adult sepsis discharges between January 1, 2012, and December 31, 2015, from Premier Healthcare Database hospitals. Sepsis was defined by an All Patients Refined Diagnosis-Related Group code of 720 (septicemia and disseminated infections). Use of four biomarker strategies was evaluated based on hospital records: (i) >1 procalcitonin (PCT), (ii) 1 PCT, (iii) no PCT but ≥1 C-reactive protein (CRP) and/or lactate and (iv) no sepsis biomarkers. Associations between biomarker use and clinical and cost outcomes were examined. The primary outcome was impact of biomarker strategy on hospital costs per day.

Results

Among 933,591 adult sepsis discharges during the study period, 731,392 (78%) had biomarker tests ordered. In multivariable analyses, discharges with >1 PCT had higher hospital costs per day ($1,904; 95% confidence interval [CI] $1,896–$1,911) compared with discharges with no sepsis biomarkers ($1,606; 95% CI $1,658–$1,664). Discharges with >1 PCT also had greater illness severity and antimicrobial exposure compared with other biomarker-use groups. The adjusted odds of dying during hospital stay compared with being discharged were significantly lower for sepsis discharges with >1 PCT (0.64; 95% CI 0.61–0.67) and 1 PCT (0.88; 95% CI 0.85–0.91) compared with no sepsis biomarker use. The proportion of discharges with ≥1 PCT increased almost six-fold during the study; use of other biomarkers remained constant.

Conclusions

Between 2012 and 2015, PCT use among sepsis discharges increased six-fold while lactate and CRP use remained unchanged. PCT use was associated with decreased odds of in-hospital mortality but increased hospital costs per day. Serial biomarker monitoring may be associated with improved patient outcomes in the most critically ill septic patients.

Changing trends in clinical characteristics and antibiotic susceptibility of Klebsiella pneumoniae bacteremia

BACKGROUND/AIMS

Klebsiella pneumoniae is second most common organism of gram-negative bacteremia in Korea and one of the most common cause of urinary tract infection, and intra-abdominal infection.

METHODS

We compared clinical and microbiological characteristics about K. pneumoniae bacteremia in a tertiary hospital between 10 years. Group A is who had K. pneumoniae bacteremia at least one time from January 2004 to December 2005. Group B is from January 2012 to December 2013. We also analyzed antibiotic resistance, clinical manifestation of the K. pneumoniae bacteremia divided into community-acquired infections, healthcare associated infections, and nosocomial infections.

RESULTS

The resistance for ampicillin, aztreonam, cefazolin, and cefotaxime significantly increased compared to 10 years ago. Extended spectrum β-lactamase positivity surged from 4.3% to 19.6%. Ten years ago, 1st, 2nd cephalosporin, and aminoglycoside were used more as empirical antibiotics. But these days, empirical antibiotics were broad spectrum such as 3rd and 4th cephalosporin. In treatment outcome, acute kidney injury decreased from 47.5% to 28.7%, and mortality decreased from 48.9% to 33.2%. In community-acquired infections, there was similar in antimicrobial resistance and mortality. In healthcare-associated and nosocomial infections, there was significantly increasing in antibiotic resistance, decreasing in mortality, and acute kidney injury.

CONCLUSIONS

In community-acquired infections, broader antibiotics were more used than 10 years ago despite of similar antimicrobial resistance. When K. pneumoniae bacteremia is suspected, we recommend to use the narrow spectrum antibiotics as initial therapy if there are no healthcare-associated risk factors, because the antibiotic resistance is similar to 10 years ago in community-acquired infections.

A literature-based economic evaluation of healthcare preventable adverse events in Europe

Purpose

To establish from the literature, cost of preventable adverse events (PAEs) to member states of the Joint Action European Union Network for Patient Safety and Quality of Care.

Data sources

We searched MEDLINE, EMBASE and CINAHL for studies in Europe estimating cost of adverse events (AEs) and PAEs (2000-March 2016). Using data from the literature, we estimated PAE costs based on national 2013 total health expenditure (THE) data reported by World Health Organization and converted to 2015 Euros.

Study selection/Data extraction

Information on type, frequency and incremental cost per episode or estimated cost of AEs was extracted. Total annual disability-adjusted life years (DALYs) resulting from PAEs in 30 EU nations were calculated using an estimate from a published study and adjusted for the percentage of AEs considered preventable.

Result of data synthesis

Published estimates of costs of AEs and PAEs vary based on the care setting, methodology, population and year conducted. Only one study was from primary care, the majority were conducted in acute care. Nine studies estimated percentage of THE caused by AEs, 13 studies calculated attributable length of stay. We estimated the annual cost of PAEs to the 30 nations in 2015 to be in the range of 17-38 billion Euros, total DALYs lost from AEs as 3.5 million, of which 1.5 million DALYs were likely due to PAEs.

Conclusion

The economic burden of AEs and PAEs is substantial. However, whether patient safety interventions will be 'cost saving' depends on the effectiveness and costs of the interventions.

Taking bacteriophage therapy seriously: a moral argument

The excessive and improper use of antibiotics has led to an increasing incidence of bacterial resistance. In Europe the yearly number of infections caused by multidrug resistant bacteria is more than 400.000, each year resulting in 25.000 attributable deaths. Few new antibiotics are in the pipeline of the pharmaceutical industry. Early in the 20th century, bacteriophages were described as entities that can control bacterial populations. Although bacteriophage therapy was developed and practiced in Europe and the former Soviet republics, the use of bacteriophages in clinical setting was neglected in Western Europe since the introduction of traditional antibiotics. Given the worldwide antibiotic crisis there is now a growing interest in making bacteriophage therapy available for use in modern western medicine. Despite the growing interest, access to bacteriophage therapy remains highly problematic. In this paper, we argue that the current state of affairs is morally unacceptable and that all stakeholders (pharmaceutical industry, competent authorities, lawmakers, regulators, and politicians) have the moral duty and the shared responsibility towards making bacteriophage therapy urgently available for all patients in need.

The investment case for preventing NICU-associated infections

BACKGROUND

Nosocomial [hospital-associated or neonatal intensive care unit (NICU)-associated] infections occur in as many as 10 to 36% of very low-birth-weight infants cared for in NICUs.

OBJECTIVE

To determine the potentially avoidable, incremental costs of care associated with NICU-associated bloodstream infections.

STUDY DESIGN

This retrospective study included all NICU admissions of infants weighing 401 to 1500 g at birth in the greater Cincinnati region from January 1, 2005, through December 31, 2007. Nonphysician costs of care were compared between infants who developed at least one bacterial bloodstream infection prior to NICU discharge or death and infants who did not. Costs were adjusted for clinical and demographic characteristics that are present in the first 3 days of life and are known associates of infection.

RESULTS

Among 900 study infants with no congenital anomaly and no major surgery, 82 (9.1%) developed at least one bacterial bloodstream infection. On average, the cost of NICU care was $16,800 greater per infant who experienced NICU-associated bloodstream infection.

CONCLUSION

Potentially avoidable costs of care associated with bloodstream infection can be used to justify investments in the reliable implementation of evidence-based interventions designed to prevent these infections.

The economic burden of patient safety targets in acute care: a systematic review

BACKGROUND

Our objective was to determine the quality of literature in costing of the economic burden of patient safety.

METHODS

We selected 15 types of patient safety targets for our systematic review. We searched the literature published between 2000 and 2010 using the following terms: "costs and cost analysis," "cost-effectiveness," "cost," and "financial management, hospital." We appraised the methodologic quality of potentially relevant studies using standard economic methods. We recorded results in the original currency, adjusted for inflation, and then converted to 2010 US dollars for comparative purposes (2010 US$1.00 = 2010 €0.76). The quality of each costing study per patient safety target was also evaluated.

RESULTS

We screened 1948 abstracts, and identified 158 potentially eligible studies, of which only 61 (39%) reported any costing methodology. In these 61 studies, we found wide estimates of the attributable costs of patient safety events ranging from $2830 to $10,074. In general hospital populations, the cost per case of hospital-acquired infection ranged from $2132 to $15,018. Nosocomial bloodstream infection was associated with costs ranging from $2604 to $22,414.

CONCLUSION

There are wide variations in the estimates of economic burden due to differences in study methods and methodologic quality. Greater attention to methodologic standards for economic evaluations in patient safety is needed.

The economics of sepsis

Sepsis, severe sepsis, and septic shock impose a growing economic burden on health care systems globally. This article first describes the epidemiology of sepsis within the United States and internationally. It then reviews costs associated with sepsis and its management in the United States and internationally, including general cost sources in intensive care, direct costs of sepsis, and indirect costs of the burden of illness imposed by sepsis. Finally, it examines the cost-effectiveness of sepsis interventions, focusing on formal cost-effectiveness analyses of nosocomial sepsis prevention strategies, drotrecogin alfa (activated),and integrated sepsis protocols.
