User Acceptance of Picture Archiving and Communication System in the Emergency Department

View Article: PubMed Central - PubMed

ABSTRACT

Background: Picture archiving and communication system (PACS) has allowed the medical images to be transmitted, stored, retrieved, and displayed in different locations of a hospital or health system. Using PACS in the emergency department will eventually result in improved efficiency and patient care. In spite of the abundant benefits of employing PACS, there are some challenges in implementing this technology like users’ resistance to accept the technology, which has a critical role in PACS success.

Objectives: In this study, we will assess and compare user acceptance of PACS in the emergency departments of three different hospitals and investigate the effect of socio-demographic factors on this acceptance.

Materials and methods: A variant of technology acceptance model (TAM) has been used in order to measure the acceptance level of PACS in the emergency department of three educational hospitals in Iran. A previously used questionnaire was validated and utilized to collect the study data. A stepwise multiple regression model was used to predict factors influencing acceptance score as the dependent variable.

Results: Mean age of participants was 32.9 years (standard deviation [SD] = 6.08). Participants with the specialty degree got a higher acceptance score than the three other groups (Mean ± SD = 4.17 ± 0.20). Age, gender, degree of PACS usage and participant’s occupation (profession) did not influence the acceptance score. In our multiple regression model, all three variables of perceived usefulness (PU), perceived ease of use (PEU) and the effect of PACS (change) had a significant effect in the prediction of acceptance. The most influencing factor was change with the beta of 0.22 (P value < 0.001).

Conclusion: PACS is highly accepted in all three emergency departments especially among specialists. PU, PEU and change are factors influencing PACS acceptance. Our study can be used as an evidence of PACS acceptance in emergency wards.

Mentions: In order to describe the acceptance issue more precisely, the model was developed in different ways and more variables have been introduced to it. According to the study conducted by Lee et al. (25), more than twenty variables including education level, computer application proficiency, socio-demographic variable, system management and support, and user’s interaction in different versions of TAM have been used. Subsequent to the investigations performed in this regard, including unified theory of acceptance and use of technology (UTAUT), Holden and Karsh’s study (21), and TAM2, the model used in the present study was selected (Figure 2). The difference between this model (similar to the model in Aldosari’s study (17)) and the TAM original model is the introduction of the change variable, and also, eliminating the effect of PEU on PU (differentiated it from UTAUT model) and omitting the attitude toward use as a variable (distinguished it from TAM2 model).
