Modeling Technical Error and Adverse Outcomes

2019-12-06 00:24:49 | BioPortfolio


The investigators' objective was to develop a theoretical model exploring the relationship between technical errors and adverse patient outcomes. To achieve this aim, the investigators interviewed surgeons from a diverse group of surgical specialties, asking them about their adverse outcomes from surgery and their most granular surgical techniques. the investigators' focus was on adverse outcomes that could be predictably associated with imperfect surgical technique and therefore prevented with proper technique.



Minute technical errors performed by the surgeon have the potential to lead to adverse patient outcomes. The objective was to gain a deeper understanding of this relationship through the development of an intraoperative model.

Materials and Methods:

The investigators used Constructivist Grounded Theory methodology, including a comprehensive review of the literature and interviews with surgeons, focusing on avoidance of technical errors. The investigators used the Observational Clinical Human Reliability Assessment system, which categorizes granular, technical intraoperative errors, as their conceptual framework. The investigators iteratively interviewed surgeons, from multiple adult and pediatric surgical specialties, refined our semi-structured interview, and developed a model. The model remained stable after interviewing 11 surgeons, and it was reviewed it with earlier interviewed surgeons.

Medical and Biotech [MESH] Definitions

Errors or mistakes committed by health professionals which result in harm to the patient. They include errors in diagnosis (DIAGNOSTIC ERRORS), errors in the administration of drugs and other medications (MEDICATION ERRORS), errors in the performance of surgical procedures, in the use of other types of therapy, in the use of equipment, and in the interpretation of laboratory findings. Medical errors are differentiated from MALPRACTICE in that the former are regarded as honest mistakes or accidents while the latter is the result of negligence, reprehensible ignorance, or criminal intent.

A measure of PATIENT SAFETY considering errors or mistakes which result in harm to the patient. They include errors in the administration of drugs and other medications (MEDICATION ERRORS), errors in the performance of procedures or the use of other types of therapy, in the use of equipment, and in the interpretation of laboratory findings and preventable accidents involving patients.

Surgical procedures employed to correct REFRACTIVE ERRORS such as MYOPIA; HYPEROPIA; or ASTIGMATISM. These may involve altering the curvature of the CORNEA; removal or replacement of the CRYSTALLINE LENS; or modification of the SCLERA to change the axial length of the eye.

Surgical techniques on the CORNEA employing LASERS, especially for reshaping the CORNEA to correct REFRACTIVE ERRORS.

Errors in metabolic processes resulting from inborn genetic mutations that are inherited or acquired in utero.
