The Preanalytical Errors In The Healthcare System

Decent Essays

The preanalytical errors increases health care costs and decreases the patient satisfaction. The laboratory errors that happen at any stage of the total testing process have influence on quality of laboratory services. Any errors that happen during this total testing process will affect the patient care that also includes unnecessary recollection of samples, delay in reporting, misdiagnosis and treatment by the clinician. Although the errors can happen at any stage of the total testing process, preanalytical errors accounts for highest percentage (70%). The consequences associated with analytical errors are significantly reduced by the use of modern laboratory instruments. But pre analytical phase is still prone to more errors due to its complexity and different stages that involved within and outside laboratory. The inaccurate reporting of results due to preanalytical errors leads to unnecessary investigations and creating an additional burden to the healthcare system (Kaushik, & Green, 2014). According to Green (2013) the healthcare economist created a model to quantify the costs associated with laboratory errors and poor sample quality. It is based on operating costs, number of beds, test volume, number of rejected samples, instrument problems and the frequency of inaccurate results reported by laboratory and their impacts. As per this model …show more content…

The different storage conditions by laboratories shows variations in sample quality that affects accurate reporting of results and leads to delay in diagnosis, treatment and prognosis. The samples that transported inappropriately causes falsely low glucose results and the leakage of cell contents in to the plasma or serum gives falsely elevated potassium, LDH and AST. The preanalytical errors are unavoidable, but proper training and quality control can prevent or minimize the errors (Kaushik, & Green,
