IMPLEMENTATION OF AN INNOVATIVE SYSTEM FOR THE PICKING OF SAMPLES FOR THE
In healthcare systems, value is centered on patient care for
which total safety and the best quality and financial management are
required. In the clinical laboratory, and considering all
daily time consuming activities, the arrival of large batches of untraceable
samples and the occupation of professionals with non-adding
value tasks (e.g. barcode reading or patient data registration prior to the
analytical phase) are faithful illustrations of activities that compromise
In this regard we present the implementation of an innovative project that
allows early management of laboratory requests from the
entire hospital with the advantages of extending the traceability of
samples, anticipate the registration of data and rationalizing the use of
pneumatic transport lines.
Methods and Materials
A Mini-Indexor® System (MIS, Maksense) connected to the
hospital’s wireless network was incorporated in the mobile transport
units that collect samples from the inpatient locations (IL) (Figure 1).
Simultaneously, MIS readers were placed in all pneumatic picking areas
(PPA), including in the emergency room (ER).
All sample barcodes were read (IL+PPA+ER) prior to transport to the
laboratory and information sent to the laboratory information system (LIS)
allowing the sample to be checked-in automatically and avoiding any
additional step at the reception besides sample sorting (Figure 2). An
evaluation was performed after one month of implementation and the
processing time of a batch of EDTA samples from the Internal Medicine
inpatient was compared to the time before MIS implementation.
After one month, 37,743 samples were recorded by all MIS, 11,285 in mobile
transport units and 26,458 in PPA and ER, without manual integration of
petitions (Figure 3, top). Considering the EDTA samples, the first sample in
batch have completed analysis within 27 minutes after reception in the
laboratory. Before MIS, the time was highly variable, ranging from 31 to 52
minutes (Figure 3, bottom).
The implementation of MIS in the intra-hospital mobile transport units of
samples and in all PPA proved to simplify the intra-laboratory
pre-analytical process, reduce and standardize the turnaround time and
enable improvement in future interventions based on documented evidence.
