Abstract

Background : Peritumoral brain edema (PTBE) of meningioma causes morbidity, poor clinical outcomes and complicates surgery. Tumor size correlates with the incidence of PTBE. However, the threshold value for tumor size that cause PTBE in meningioma has not been widely studied. Objective: To determine the threshold value for meningioma size that can predict the incidence of peritumoral edema in general and based on specific intracranial locations on pre-operative head MRI.Methods: This is a cross sectional study on patients with intracranial meningioma who had undergone head MRI imaging at Dr.Sardjito Hospital in the period of 2018-2022 retrospectively. An analysis was carried out to find the threshold value for meningioma size and the prevalence ratio to predict the incidence of PTBE. Results: The cut-off volume for intracranial meningioma was >44 cm3 with RP of 3.61 (p=0.01) in general. Simultaneously, large tumor volume (≥44 cm3) has the strongest correlation to the incidence of peritumoral edema (p=0.01). The cut-off volume for meningioma in supratentorial non-skull base was >22 cm3 with RP of 2.54, while in supratentorial skull base was >54 cm3 with RP of 23.33 (p=0.01). The cut off volume for meningioma in infratentorial region was >19.75 cm3 with RP 3.0 (p=0.52). Conclusion: The cut-off value for intracranial meningioma volume to predict the incidence of peritumoral edema is 44 cm3. There are differences in the cut-off values of meningioma volume and prevalence ratios based on specific intracranial locations to predict the incidence of PTBE in meningioma.

Abstract

Background: RSUP Dr. Sardjito implemented Picture Archiving and Communication (PACS)/ Radiology Information System (RIS) in 2016, achieving a filmless radiology service by July 2020. However, evaluations of this implementation among doctors using a Technology Acceptance Model (TAM) variant have not been conducted.Objective: This research aimed to evaluate PACS/RIS implementation among doctors at RSUP Dr. Sardjito based on perception (usefulness, ease of use, work efficiency) and acceptance levels.Methods: This cross-sectional observational study involved 294 randomly selected physician respondents across 13 clinical departments. Data were gathered using a validated and reliable online questionnaire.Results: The majority of respondents (>60%) demonstrated high perception and acceptance scores (60.2% response rate). Age, specialization, length of service at the hospital, career duration, and training history were significantly associated with system perception and acceptance (P<0.05). Work efficiency exhibited the strongest positive correlation with acceptance (r=0.831), followed by perceived ease of use (r=0.703) and perceived usefulness (r=0.632).Conclusion:  The PACS/RIS implementation has been well-executed and is influenced by doctors' professional characteristics. Perceived work efficiency stands as the variable with the strongest positive correlation to acceptance levels.
