Introduction: Primary health care plays an important role in healthcare systems. In Malaysia, One (1) Malaysia Clinic (now known as Community Clinic since 2018) was established in 2010 aims to increase healthcare services accessibility within the poor urban population. The aim was to look at the effectiveness of One (1) Malaysia Clinic as a new form of public primary health clinic by looking at expectations and perceptions of the quality of the provided services by the patients. Method: It applied a cross sectional study involving nine clinics in of the busiest district in Kelantan namely, Kota Bharu district. 386 respondents which were Malaysian citizen, 18 years old and above were involved in this study. The survey used Malay validated SERVQUAL questionnaire. The Service Quality (SQ) gap was calculated. Result: The empathy dimension obtained the highest expectation and perception score, while the tangi- ble dimension has the lowest expectation and perception score. In all SERVQUAL dimension, the expectations and perceptions of the service provided was significantly different with P < 0.001. The most critical dimension identified was tangible dimension as it has the largest negative SQ gap score. Conclusion: Negative gaps for all SERVQUAL dimensions and individual items indicated that provided services at One (1) Malaysia Clinic still could not fulfilled the patient’s expectation. A continuous improvement program is needed especially on tangible dimension in deliv- ering a quality healthcare services.
