Applying lean principles to continuous renal replacement therapy processes

The impact of lean management on frontline healthcare professionals: a scoping review of the literature

BACKGROUND

Lean management practices are increasingly used in hospitals. However, their impacts on staff have not been systematically synthesised. This scoping review aims to synthesise the evidence on the effects of Lean Management practices on frontline healthcare professionals.

METHODS

A search was conducted in February 2020 on multiple databases to identify relevant sources. Studies had to satisfy the following inclusion criteria to be considered: published in English or French, peer-reviewed, empirical, studied the use of Lean in a healthcare setting and focused on its impacts on frontline workers. The studies included were heterogeneous in terms of participants. Findings were coded and classified using a thematic analysis. The quality and methodological rigour of the reviewed articles were assessed to establish a level of confidence in their findings.

RESULTS

Of 998 identified articles, 17 were included in the review. The findings were coded into four themes: (1) Morale, motivation and job satisfaction (n = 9, 2) work intensification, job strain, anxiety, stress and dehumanisation (n = 7, 3) teamwork, communication and coordination (n = 6); and (4) learning, innovation and personal development (n = 3). Overall, the articles reported positive (n = 11), negative (n = 3) and mixed (n = 3) impacts of Lean on frontline healthcare professionals.

CONCLUSION

This review is the first to synthesise and highlight the gaps in the existing literature examining the impacts of Lean on frontline health professionals. The review revealed a range of both positive, negative and mixed effects, and points to the need for more empirical research to identify the underlying reasons leading to these outcomes.

Preparation times and costs for various solutions used for continuous renal replacement therapy

PURPOSE

Results of a study to determine time and cost requirements for final preparation of continuous renal replacement therapy (CRRT) products are reported.

METHODS

A 3-phase observational study was conducted at a tertiary care university hospital to evaluate costs associated with manual addition of phosphate and/or potassium to 3 commercial 5-L CRRT products. In the first phase of the study, pharmacy workflow processes for solution preparation were established; in the second phase, pharmacist and pharmacy technician time spent in the CRRT workflow and all materials used were observed and recorded. In the third phase, time and personnel requirements were analyzed in economic terms to estimate final preparation costs.

RESULTS

Through direct observation over 35 days, the CRRT workflow was observed and work times recorded for 511 bag preparations. The main cost contributors were the base CRRT solution and electrolyte additive prices. Technician compounding time differed substantially by solution brand and the need for electrolyte addition. Pharmacist verification time did not differ meaningfully by product.

CONCLUSION

Preparation and verification of premade CRRT solutions that contained physiological electrolyte concentrations required less technician and pharmacist time than solutions that needed addition of electrolytes in the pharmacy. Personnel costs, which were a small part of the total cost of dispensed CRRT bags, were higher for technicians than pharmacists. The baseline costs of the solutions and the electrolyte additives, if needed, were the main contributors to total cost.

Prevention of hypophosphatemia during continuous renal replacement therapy-An overlooked problem

Hypophosphatemia is a common and potentially serious complication occurring during continuous renal replacement therapy (CRRT). Phosphate supplementation is required in the vast majority of patients undergoing CRRT, particularly beyond the first 48 hours. Supplementation can be provided either as a standalone oral or parenteral treatment or as an additive to CRRT solutions. Each approach has advantages and disadvantages, and clinicians must weigh the individual factors most relevant in their practice setting. Currently there are no consensus protocols for phosphate replacement in CRRT, and many centers replete phosphate in response to hypophosphatemia as opposed to pre-emptively. Repletion protocols have also been challenged in recent years by shortages in injectable phosphate solutions. More recently a commercially available phosphate-containing CRRT solution was approved in the United States, but there has been limited clinical experience with this product. In this review, we present recommendations for phosphate repletion in CRRT to prevent hypophosphatemia, and describe our experience using phosphate-containing CRRT solutions.

Optimal Role of the Nephrologist in the Intensive Care Unit

As advances in Critical Care Medicine continue, critically ill patients are surviving despite the severity of their illness. The incidence of acute kidney injury (AKI) has increased, and its impact on clinical outcomes as well as medical expenditures has been established. The role, indications and technological advancements of renal replacement therapy (RRT) have evolved, allowing more effective therapies with less complications. With these changes, Critical Care Nephrology has become an established specialty, and ongoing collaborations between critical care physicians and nephrologist have improved education of multi-disciplinary team members and patient care in the ICU. Multidisciplinary programs to support these changes have been stablished in some hospitals to maximize the delivery of care, while other programs have continue to struggle in their ability to acquire the necessary resources to maximize outcomes, educate their staff, and develop quality initiatives to evaluate and drive improvements. Clearly, the role of the nephrologist in the ICU has evolved, and varies widely among institutions. This special article will provide insights that will hopefully optimize the role of the nephrologist as the leader of the acute care nephrology program, as clinician for critically ill patients, and as teacher for all members of the health care team.

Quality measures for acute kidney injury and continuous renal replacement therapy

PURPOSE OF REVIEW

Quality and safety are important priorities in the care of critically ill patients. For patients with acute kidney injury (AKI) or for those receiving continuous renal replacement therapy (CRRT), measures and outcomes associated with quality of care have been suboptimally developed and evaluated. The review is timely as it summarizes current quality practices in AKI and CRRT, and presents ongoing and future developments.

RECENT FINDINGS

The review begins with the history of quality and safety in healthcare. We then discuss the current quality of care offered in AKI and CRRT. Quality measure development methodology, such as plan-do-study-act and the focus-analyze-describe-execute models and lean thinking are then presented and discussed. Finally, recent evidence for quality in AKI and CRRT care, including proposed quality measures, are discussed.

SUMMARY

Few studies have examined the quality of care provided to patients with AKI and CRRT. Evidence suggests opportunities to improve the quality of care received by patients at risk of or who have developed AKI. Priorities for improving quality of care exist across several important themes including risk identification, diagnosis, monitoring, investigation, and strategies for management. Similarly, evidence-informed quality measures of CRRT care have not been rigorously evaluated. These are important knowledge-to-care gaps that require further investigation.
