Quantifying and Predicting Surgeon Work Input in Primary vs Revision Total Hip Arthroplasty

The Journal of Arthroplasty

Abstract

Primary total hip arthroplasties (THAs) performed annually are projected to increase 174% by 2030, causing a parallel increase for revision THA. Increased surgical effort and readmission rates associated with revision THA may discourage surgeons from performing them. Although revision THA Medicare reimbursement is greater, it may be disproportionate to time and effort. We examined work input between primary and revision THA, assessing predictive factors. We also compared surgeon work input to current reimbursement. A total of 156 patients were identified, 80 primary and 76 revision THA. Demographic, clinical, and radiographic data were collected. Radiographic data were collected from the most recent preoperative radiographs taken before primary or revision THA. Multiple linear and logistic regression models were used to identify patient factors contributing to select outcome variables by a stepwise method, with a probability value for entry (P = .05) and removal (P = .10). Residual analysis was performed, confirming validity of these models. Average age, body mass index, and percentage of female patients were similar between cohorts. There was no statistically significant difference between the demographic variables, although d...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
