Reducing the number of unnecessary liver function tests requested on the Paediatric Intensive Care Unit

Rethinking Blood Testing in Pediatric Cancer Patients: A Quality Improvement Approach

Introduction:

The overuse of blood tests burdens the healthcare system and can detrimentally impact patient care. Risks of frequent blood sampling include infection and clinician-induced anemia, which can negatively impact patients and their families. Pediatric cancer patients are particularly vulnerable as they are immunocompromised with a small blood volume. Four blood tests had become a daily practice. Therefore, we aimed to reduce the number of blood tests taken per bed day within the inpatient pediatric cancer unit by 15% within 8 months.

Methods:

This quality improvement project combined several strategies to reduce test frequency and empower clinicians on the rationale for blood test ordering. Recommendations were developed collaboratively presented in a summary table. Targeted behavior-change methodology built engagement and momentum for the change. All clinicians were challenged to STOP and THINK about why a test is necessary for each patient. The primary outcome measure was the frequency of the tests taken per bed day. Frequency was compared between pre- and postimplementation plus follow-up periods across 2019–2021.

Results:

26,941 blood tests were captured in 1,558 admissions. The intervention led to an overall blood test reduction of 37% over 8 months. Liver Function Tests were the standout, with a 52% decrease in test frequency.

Conclusions:

A strategy incorporating education and culture change, combined with clear guidance on testing frequency, significantly reduced the ordering frequency of blood tests without increased patient harm.

Effects of de-implementation strategies aimed at reducing low-value nursing procedures: a systematic review and meta-analysis

Background

In the last decade, there is an increasing focus on detecting and compiling lists of low-value nursing procedures. However, less is known about effective de-implementation strategies for these procedures. Therefore, the aim of this systematic review was to summarize the evidence of effective strategies to de-implement low-value nursing procedures.

Methods

PubMed, Embase, Emcare, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials, Web of Science, and Google Scholar were searched till January 2020. Additionally, reference lists and citations of the included studies were searched. Studies were included that described de-implementation of low-value nursing procedures, i.e., procedures, test, or drug orders by nurses or nurse practitioners. PRISMA guideline was followed, and the ‘Cochrane Effective Practice and Organisation of Care’ (EPOC) taxonomy was used to categorize de-implementation strategies. A meta-analysis was performed for the volume of low-value nursing procedures in controlled studies, and Mantel–Haenszel risk ratios (95% CI) were calculated using a random effects model.

Results

Twenty-seven studies were included in this review. Studies used a (cluster) randomized design (n = 10), controlled before-after design (n = 5), and an uncontrolled before-after design (n = 12). Low-value nursing procedures performed by nurses and/or nurse specialists that were found in this study were restraint use (n = 20), inappropriate antibiotic prescribing (n = 3), indwelling or unnecessary urinary catheters use (n = 2), ordering unnecessary liver function tests (n = 1), and unnecessary antipsychotic prescribing (n = 1). Fourteen studies showed a significant reduction in low-value nursing procedures. Thirteen of these 14 studies included an educational component within their de-implementation strategy. Twelve controlled studies were included in the meta-analysis. Subgroup analyses for study design showed no statistically significant subgroup effect for the volume of low-value nursing procedures (p = 0.20).

Conclusions

The majority of the studies with a positive significant effect used a de-implementation strategy with an educational component. Unfortunately, no conclusions can be drawn about which strategy is most effective for reducing low-value nursing care due to a high level of heterogeneity and a lack of studies. We recommend that future studies better report the effects of de-implementation strategies and perform a process evaluation to determine to which extent the strategy has been used.

Trial registration

The review is registered in Prospero (CRD42018105100).

Sustainable approach to reducing unnecessary combined biochemistry tests on a paediatric cardiology ward

We describe a quality improvement project (QIP) designed to reduce unnecessary biochemistry samples requested on a paediatric cardiology ward in Great Ormond Street Hospital. Prior to the intervention biochemistry tests were requested on a daily basis by nursing and junior doctor staff at an annual cost of around £27 000 for the ward. The lead author observed that for the majority the true indication for these biochemistry tests was for the purpose of monitoring renal function and plasma electrolytes. However, during a diagnostic analysis trying to understand the behaviours around ordering tests it appeared that a broader profile and more expensive combined test set was being requested that included unnecessary liver and bone profile analyses. A driver diagram identified three areas to target in order to rationalise blood test requests: (1) a critical understanding of the purpose of the test by those requesting the tests; (2) effective communication between professionals; and (3) improved utilisation of the computer system. An education-based QIP was initiated with the aim of reducing requests of these costly, unnecessary combined biochemical tests by half, by supporting and encouraging staff to switch to a simpler renal function assay. The project was designed to be engaging and fun and invited clinical teams to consider the cost of wasted resources in terms of the financial implications for the hospital, and in terms of the wider environmental impact of wasted resources illustrated in terms of estimated carbon dioxide use. This perhaps unusual approach of encouraging an awareness of both financial and environmental cost led to a sustained reduction in the ordering of expensive combined biochemical tests, saving an estimated £11 338 (or 13.5%) on biochemistry tests and around 17.8 tonnes of carbon dioxide across a 32-month follow-up period.
