Inappropriate laboratory test utilization in outpatient tertiary care: Implications for value-based healthcare.

OBJECTIVES: To assess the rate of inappropriate repetition of laboratory testing and estimate the cost of such testing for thyroid stimulating hormone (TSH), total cholesterol, vitamin D, and vitamin B12 tests. METHODS: A retrospective cohort study was carried out in the Family Medicine and Polyclinic Department at King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia. Clinical and laboratory data were collected between 2018-2021 for the 4 laboratory tests. The inappropriate repetition of tests was defined according to international guidelines and the costs were calculated using the hospital prices. RESULTS: A total of 109,929 laboratory tests carried out on 23,280 patients were included in this study. The percentage of inappropriate tests, as per the study criteria, was estimated to be 6.1% of all repeated tests. Additionally, the estimated total cost wasted amounted to 2,364,410 Saudi Riyals. Age exhibited a weak positive correlation with the total number of inappropriate tests (r=0.196, p=0.001). Furthermore, significant differences were observed in the medians of the total number of inappropriate tests among genders and nationalities (p<0.001). CONCLUSION: The study identified significantly high rates of inadequate repetitions of frequently requested laboratory tests. Urgent action is therefore crucial to overcoming such an issue.

The process of litigation for medical errors in Saudi Arabia and the United Kingdom.

Efficient process of litigation of medical errors is a key to ensure fair, speedy, and accessible justice system. The conditions of establishing medical negligence are similar in both legal systems. These conditions include the duty of care, breach of that duty of care, the damages, and establishing causation. A culture of litigation and compensation is growing in the United Kingdom and Kingdom of Saudi Arabia; however the cost of medical claims and awarded compensations are much more in the United Kingdom compared to Kingdom of Saudi Arabia. In Kingdom of Saudi Arabia, there is a need for more transparency in the documentation and publication of litigated medical errors. In addition, there is a need to introduce interventions to shorten the duration of litigation in both legal systems. Financial caps on awarded compensation and caps on expert and legal fees are potential strategies to control the cost of medical errors which seems to work well in the Saudi model.
