ABSTRACT
Context: Laboratory testing constitutes an integral part of patient management and has an extensive influence on medical decision-making. The completion of laboratory investigation request forms is a vital aspect of the highly variable pre-analytical phase of laboratory testing.Aim: We aimed to assess the adequacy of completion of investigation request forms received at our laboratory.Methods: An audit of systematically selected laboratory investigation request forms received over a six-month period at our laboratory was performed to assess the degree of completion of these forms by requesting clinicians. Data was analysed using Microsoft Excel®.Results: Two hundred and fifty four request forms were reviewed. None of the reviewed forms was adequately completed. The clinician's contact number was missing in all the request forms. About two-thirds of the request forms did not have the patient's hospital number (66.1%) and the referring clinician's signature (66.9%) available on them. The clinical diagnosis of the patient was not stated in 18.9% of the request forms. The patient's name, gender and age were the most frequently completed parameters in 100.0%, 98.4% and 97.2% of the request forms respectively.Conclusion: Basic information required for the accurate interpretation of laboratory results are missing in several request forms. This may have deleterious impact on laboratory turn around time, healthcare costs and patient management as most medical decisions are influenced by laboratory results
