Influence of the living Pareto chart and data transparency on patient outcomes in neurosurgery

Abstract

Objective: Quality improvement (QI) tools are increasingly being used to calibrate healthcare quality. Achieving healthcare quality is essential, as there is a movement toward value-based healthcare delivery. Visual management, such as a living Pareto chart, is a strategy for improvement within the QI framework. The authors herein hypothesized that transparency of data through a living Pareto chart is a powerful way to improve patient outcomes and gain clinical efficiency.

Methods: The authors retrospectively reviewed patient outcomes and complications; cerebrospinal fluid (CSF) leaks; shunt, baclofen, and other surgical site infections; readmission rates; and same- or next-day appointments in a cohort of patients at the Riley Hospital for Children from November 1, 2016, to May 31, 2020. Similarly, they reviewed neurosurgical outcomes and complications at a second institution, the Oklahoma Children's Hospital, where a living Pareto chart was utilized from February 1, 2021, to March 31, 2022. The discrete frequency and rates per month of outcomes and complications were graphed on scatterplots, Pearson correlation coefficients were calculated to measure the strength of the relationship between event frequency and time, and best-fit lines illustrated the relationship between those points through the least-squares method.

Results: At both the Riley Hospital for Children and Oklahoma Children's Hospital, the use of a living Pareto chart to display data transparently was associated with decreasing infections, and it was associated with decreasing readmissions at Riley. On the other hand, it encouraged same- or next-day clinic appointments to be offered to patients and families. Interestingly, CSF leaks were not mitigated with data transparency alone.

Conclusions: Transparency is a driver of change in patient, provider, and institutional behaviors. It is an essential element of QI and patient safety, as well as building a culture of trust. Readmissions, infections, and same- or next-day appointments were influenced by the living Pareto chart; however, CSF leaks remained recalcitrant to data transparency. Other QI strategies may be necessary to positively affect the occurrence of CSF leaks in neurosurgery.
