The Cost of Pre-Analytical Errors in INR Testing at a Tertiary-Care Hospital Laboratory: Potential for Significant Cost Savings

Direct costs of blood drawings with pre-analytical errors in tertiary paediatric hospital care

BACKGROUND

Blood drawings is a common hospital procedure involving laboratory and clinical disciplines that is important for the diagnosis and management of illnesses in children. Blood drawings with pre-analytical error (PAE) can lead to increased costs for hospitals and healthcare organisations. The direct cost of blood drawings after a PAE is not fully understood in paediatric hospital care.

AIM

The aim of this study was to estimate the average direct cost of PAE per year and per 10,000 blood drawings in tertiary paediatric care.

METHODS

A cost analysis using a bottom-up approach was conducted on the basis of combined information from the hospital's laboratory register for the period 2013-2014 and clinical in-ward observations at a tertiary children's referral hospital in Sweden, the Astrid Lindgren Children's Hospital. For the analysis, we hypothesised the re-collection of all blood drawings with PAE and included the average costs of the sampling materials, the time of the healthcare personnel, the laboratory analyses, and in-ward premises based on the time spent on the blood sampling procedure.

RESULTS

The annual cost of PAE was estimated to be 74,267 euros per 54,040 blood drawings, which corresponds to 13,756 euros per 10,000 blood drawings or 1.5 euros per draw. The personnel cost represented 60.1% (45,261 euros per year) of the cost due to PAE, followed by costs for hospitalisation (25.2%), laboratory analyses (8.1%), and materials (5.7%).

CONCLUSION

PAEs lead to substantial increases in the costs in tertiary paediatric hospital care. If these PAEs can be avoided, costs related to the re-collection of blood drawings with PAE may be re-allocated to other health-promoting activities for children visiting hospital institutions.

Preanalytical Errors in Clinical Biochemistry Laboratory and Relationship With Hospital Departments and Staff: A Record-Based Study

OBJECTIVE

Despite many efforts to improve the overall quality of clinical laboratory service, errors that compromise patient safety and increase healthcare costs continue to occur even infrequently. We aimed to determine the causes of preanalytical errors and related factors by evaluating the laboratory records of a tertiary hospital.

METHODS

In this retrospective study, 7,762,981 requests that were registered in the biochemistry laboratory records of Ondokuz Mayıs University Health Practice and Research Center during 2019 were examined. All rejected samples were analyzed according to the department where they were collected and the reasons for rejection.

RESULTS

Of the total sample rejections, 99,561 (74.8%) were preanalytical and 33,474 (25.2%) belonged to the analytical phase. The preanalytical rejection rate was 1.28%, with the highest rejection rate in the inpatients (2.26%) and the lowest in the outpatients (0.02%). Insufficient sample (43.7%), clotted sample (35.1%), and inappropriate sample (11.1%) were the first 3 rows of rejection reasons. It was determined that sample rejection rates were low during routine working hours and high during nonworking hours.

CONCLUSIONS

Preanalytical errors were most common in inpatient wards and were most likely due to incorrect phlebotomy techniques. Education of health personnel on good laboratory practices, systematic monitoring of errors, and the development of quality indicators will play an important role in reducing the vulnerability of the preanalytical phase.

Senior nursing students' reflections on deviations from guideline adherence regarding venous blood specimen collection practice: A qualitative study

BACKGROUND

Venous blood specimen collection is a common procedure within healthcare and both diagnoses as well as treatment evaluation, are often based on results from these analyses. However, studies among both students and staff have demonstrated suboptimal adherence to venous blood specimen collection practice guidelines which in turn might jeopardize patient safety.

OBJECTIVES

This study aimed to describe final semester nursing students' experiences of deviations from venous blood specimen collection practice guidelines during clinical training.

METHODS

This study adopted a qualitative design. Twentysix final (6th) semester nursing students were recruited through purposive sampling at a Swedish university. Data were collected through semi-structured, face-to-face, focus group interviews in September 2015. The transcribed interviews were analyzed using qualitative content analysis.

RESULTS

The students' experiences generated two categories; 1) Striving to blend in (subcategories Feeling uncomfortable and Adapting to the prevailing practice culture) and 2) Diminished confidence (subcategories Being confused due to inconsistency and Being uncertain about guideline usefulness) forming the overall theme Being a copycat.

CONCLUSION

The research concludes that nursing students adapt to the prevailing practice culture encountered during clinical training, often at the expense of guidelines adherence. Since the students are being assessed during clinical training, the eagerness to belong to the team and be well-liked might be stronger than the ambition to follow guidelines. As a consequence, nursing students in clinical training might become copycats by aligning themselves with the prevailing practice culture which in turn might jeopardize adherence with VBSC guideline practice and thereby patient safety. With the ambition to support nursing students' learning in clinical training, facilitators of learning to comprise both students and supervisors need to be further addressed.

TWEETABLE ABSTRACT

Nursing students adapt to the prevailing venous blood sample collection practice culture and become copycats.
