Morristown Medical Center Team Finds No Difference in Infection Rates, Significant Cost Savings Between Antibiotic-Loaded Bone Cement and Plain Cement in Retrospective Analysis

February 20, 2019

Study Presented at the National Meeting of the Orthopedic Research Society

FEBRUARY 20, 2019, Morristown, NJ – A study conducted by a team from the total joint and perioperative service at Atlantic Health System’s Morristown Medical Center found that there was no difference in infection rates between antibiotic-loaded bone cement (ALBC) vs. “plain” cement after primary total joint reconstruction/replacement.

For the past few decades, hospitals have opted to use ALBC over plain cement after primary total joint reconstruction/replacement because of its potential to decrease infection rates.

“As hospitals continue to find ways to improve both patient care and affordability in the wake of bundled payment models and changing payment methods, providers must reduce unnecessary costs in order to increase quality and improve efficiency—and this study proves that plain cement is as effective and more cost-effective than ALBC,” said Dr. James Wittig, our Chairman, Orthopedic Surgery and Medical Director of Orthopedics, Orthopedic Oncology and Sarcoma Surgery, Atlantic Health System, who presented the study at the National Meeting of the Orthopedic Research Society.

Methods

The team conducted a retrospective analysis of 4,116 hip or knee arthroplasty cases performed at Morristown Medical Center between 2016 and 2018. Of 3,968 knee cases, 3,442 received plain cement, and 526 received ALBC. Of 148 hip cases, 71 received plain cement, and 77 received ALBC.

A statistical analysis was performed using Fisher’s exact test and the National Healthcare Safety Network’s surgical site guidelines.

Cost Savings

In addition to no statistically significant difference in infection rates between the cements, the study found plain cement yields a significant cost saving.

In the retrospective analysis, the team found that a total of 989 bags of ALBC were used in 526 knee surgeries and 130 bags in 77 hip cases.

The cost for one bag of ABLC for hip and knee arthroplasty was $363.23 and $335.96 respectively. The cost for one bag of plain cement for hip and knee arthroplasty was $73.98 and $72.16, respectively, making the total cost of ALBC in knee arthroplasty $332,264.44 and hip arthroplasty was $47,219.90.

The team’s analysis found that using plain cement at all indexed procedures would have resulted in a total savings of $298,500.70.

Results

“Our study demonstrates that routine use of antibiotic cement for primary joint replacements is not associated with a lower infection rate compared to use of plain cement, which is much more cost effective,” said Wittig.
