Clinical pathway efficiency for elective joint replacement surgeries: a case study

Abstract

Purpose

The purpose of this paper is to define a clinical pathway for total joint replacement (TJR) surgery, estimate the effect of delays between steps of the pathway on wait time for surgery and to identify factors contributing to more efficient operations and challenges to their implementation.

Design/methodology/approach

This is a case study with a mixed methods approach. The authors conducted interviews with hospital staff. Data collected in the interviews and through on-site observation were analyzed to map the TJR process and identify the steps of the care pathway. The authors extracted and analyzed data (time stamps) from 60 hospital patient records for each step in the pathway and ran a regression on the duration of the whole trajectory.

Findings

There were wide variations in the delays observed between the seven steps identified. The delay between Step 1 and Step 2 was the only significant variable in predicting the total wait time to surgery. In one hospital, one delay explained 50 percent of the variation. There was misalignment between findings from the qualitative data in terms of strategies implemented to increase efficiency of the clinical pathway to the quantitative data on delays between the steps.

Research limitations/implications

The study identified the clinical pathway from the consultation with an orthopaedic surgeon to the surgery. However, it did not go beyond the surgery. Future research could investigate the relationship between specific processes and delays between steps of the process and patient outcomes, including length of stay, mobilization and functionality in activities of daily living, as well as potential complications from surgery, readmission and the services required after the patient was discharged.

Practical implications

Wait times can be addressed by implementing strategies at the health system level or at the organizational level. The authors found and discuss areas where there could be efficiency gains for health care organizations.

Social implications

Stakeholders in care processes are diverse and they each have their preferences in how they practice (in the case of providers) and how they perceive and wish to respond adequately to patients’ needs in contexts that have different norms and approaches. The approach in this study enables a better understanding of the processes, the organizational culture and how these may affect each other.

Originality/value

Our mixed methods enabled a process mapping and the identification of factors that significantly affected the efficiency of the TJR surgery process. It combines methods from process engineering with health services and management research. To some extent, this study demonstrates that although managers can define and enforce processes, organizational culture and practices are harder to influence.
