Abstract

Opportunity cost is the value of an activity forgone for participation in some other activity. With respect to surgery, an innovation incurs an opportunity cost when it uses additional operating time that could otherwise be used in a productive way. This report describes an example of assessing opportunity cost in the transition from open to laparoscopic colectomy using pooled analysis data from the surgical literature and hospital financial data. A MEDLINE literature search was performed between the years 1998 and 2008. Data were pooled from the identified studies used for the statistical analysis of cost and operating room time differences between laparoscopic versus open colectomy. The analysis identified five commonly performed, elective general surgery procedures. The profit margins of these procedures then were determined and divided by their average surgical time to calculate a range of opportunity cost multipliers. Finally, these opportunity cost multipliers were applied to the additional time required for performance of laparoscopic colectomy to demonstrate that procedure's true overall cost. Seven comparative studies were identified. The pooled analysis showed that the operating time was longer for a laparoscopic cole...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.

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.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Signaling in Adult Neurogenesis

Neural stem cells play a critical role in the production of neuronal cells in neurogenesis is of great importance. Of interest is the role signalling mechanisms in adult neurogenesis. Discover the latest research on signalling in adult neurogenesis.

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.
