The Influence of Technology Acceptance Model Factors and Modification of Roy's Adaptation Theory on the Use of Online Registration Applications in Hospital: A PLS-SEM Analysis Approach

Abstract

Introduction: The implementation of online registration applications in hospital outpatient services represents a significant technological advancement in healthcare service delivery.

Objective: This study aimed to analyze factors influencing the use of online registration applications at the outpatient clinic of RSUD dr. Loekmono Hadi Kudus using the Technology Acceptance Model (TAM) framework integrated with Roy's Adaptation Theory.

Methods: The research employed a quantitative approach with a cross-sectional design, involving 99 respondents who were outpatient clinic users. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) and Importance-Performance Map Analysis (IPMA).

Results:  showed that perceived ease of use (p=0.0200) and behavioral intention (p=0.0091) significantly influenced the actual use of the online registration application, while perceived usefulness (p=0.2885) and attitude toward use (p=0.5515) did not demonstrate significant effects. IPMA identified behavioral intention as the highest priority factor with good performance, while perceived ease of use showed importance but required performance improvement.

Conclusion: The integration of TAM with Roy's Adaptation Theory provided a comprehensive understanding of user behavior in healthcare technology adoption. These findings offer strategic insights for improving online registration system implementation in regional hospitals, particularly by enhancing system usability and strengthening user behavioral intention through targeted education and technical support.
