Abstract

BACKGROUND: We aimed to provide an overview of all diagnostic tools developed to diagnose appendicitis with their reported accuracy and to further characterize these including their need for diagnostic equipment.

METHODS: This scoping review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews and a protocol was registered at Open Science Framework. We performed a systematic literature search in PubMed, Embase, China National Knowledge Infrastructure, Índice Bibliográfico Espanhol de Ciências da Saúde, and Latin American and Caribbean Health Sciences Literature. We included original articles of all languages with the purpose to derive an accessible diagnostic tool. We extracted data regarding study- and diagnostic tool characteristics, and the accuracy of each diagnostic tool.

RESULTS: The search led to 6419 records, where 74 studies were included, yielding 82 diagnostic tools reported in seven different languages. Among these tools, 35% included patient characteristics, 85% symptoms, 93% physical examinations, 37% vital signs, 78% laboratory values, and 16% imaging. Among the diagnostic tools, 35% relied on a medical doctor/surgeon with access to a laboratory, and six diagnostic tools did not require a bedside medical doctor/surgeon. The median positive predictive value, negative predictive value, sensitivity, and specificity across diagnostic tools were 91%, 94%, 89%, and 86%, respectively.

CONCLUSIONS: We identified 82 diagnostic tools that most frequently were based on symptoms and physical examinations. Most diagnostic tools relied on a medical doctor/surgeon with access to laboratory values. The accuracy was high across the diagnostic tools.
