What is he best known for?
The fields of study he is best known for:
- Surgery
- Internal medicine
- Cancer
His primary scientific interests are in Surgery, Esophagectomy, Mortality rate, Perioperative and Intensive care medicine.
John D. Birkmeyer mostly deals with Retrospective cohort study in his studies of Surgery.
His study in Esophagectomy is interdisciplinary in nature, drawing from both Cystectomy, Pancreatectomy and Carotid endarterectomy.
His Mortality rate study which covers Abdominal aortic aneurysm that intersects with Abdominal surgery and Aortic valve replacement.
As a part of the same scientific study, John D. Birkmeyer usually deals with the Perioperative, concentrating on Laparoscopy and frequently concerns with Umbilical hernia, Hernia, Laparotomy and Hernia repair.
His Intensive care medicine research incorporates elements of Quality, Surgical care, Complication and Process.
His most cited work include:
- Hospital Volume and Surgical Mortality in the United States (3933 citations)
- Surgeon volume and operative mortality in the United States. (1442 citations)
- Surgeon volume and operative mortality in the United States (1031 citations)
What are the main themes of his work throughout his whole career to date?
Surgery, Internal medicine, Mortality rate, Emergency medicine and General surgery are his primary areas of study.
His research in Surgery intersects with topics in Odds ratio, Esophagectomy and Epidemiology.
His Esophagectomy study integrates concerns from other disciplines, such as Abdominal aortic aneurysm, Cystectomy, Carotid endarterectomy and Pneumonectomy.
His Internal medicine research is multidisciplinary, relying on both Oncology and Cardiology.
John D. Birkmeyer interconnects Aortic valve replacement, Colectomy, Intensive care medicine, Mitral valve replacement and Risk factor in the investigation of issues within Mortality rate.
The Emergency medicine study combines topics in areas such as Referral and Medical emergency.
He most often published in these fields:
- Surgery (60.64%)
- Internal medicine (19.24%)
- Mortality rate (19.83%)
What were the highlights of his more recent work (between 2011-2020)?
- Surgery (60.64%)
- Emergency medicine (14.58%)
- Retrospective cohort study (10.50%)
In recent papers he was focusing on the following fields of study:
His main research concerns Surgery, Emergency medicine, Retrospective cohort study, Medical emergency and Intensive care medicine.
John D. Birkmeyer studied Surgery and Odds ratio that intersect with Logistic regression.
His Emergency medicine research also works with subjects such as
- Confidence interval that connect with fields like Surgical procedures,
- Quality of care together with Health reform.
While the research belongs to areas of Retrospective cohort study, John D. Birkmeyer spends his time largely on the problem of Cohort study, intersecting his research to questions surrounding Colectomy.
His Medical emergency study combines topics from a wide range of disciplines, such as Hospital quality, Ambulatory, Outpatient surgery and Surgical care.
John D. Birkmeyer combines subjects such as Survival rate, Mortality rate, Vascular surgery, Perioperative and Failure to rescue with his study of Intensive care medicine.
Between 2011 and 2020, his most popular works were:
- Surgical Skill and Complication Rates after Bariatric Surgery (754 citations)
- Hospital volume and operative mortality in the modern era. (309 citations)
- Understanding of regional variation in the use of surgery (281 citations)
In his most recent research, the most cited papers focused on:
- Surgery
- Internal medicine
- Cancer
John D. Birkmeyer mainly investigates Surgery, Complication, Retrospective cohort study, Surgical procedures and Emergency medicine.
In his research, John D. Birkmeyer undertakes multidisciplinary study on Surgery and Risk assessment.
As part of the same scientific family, John D. Birkmeyer usually focuses on Complication, concentrating on Laparoscopic gastric bypass and intersecting with Surgical skills and Physical therapy.
His Retrospective cohort study research is multidisciplinary, incorporating perspectives in Logistic regression, Significant difference, Carotid endarterectomy, Insurance coverage and Esophagectomy.
John D. Birkmeyer has researched Surgical procedures in several fields, including Geographic variation and Quality management.
His Emergency medicine research includes elements of Quality of care, Confidence interval, Lower extremity bypass and Medical emergency.
