This is a conceptual paper to analyse the patient-centred decision-making approach adopted in healthcare in Malaysia. This study reviews literature on the history of patient-centeredness and the requirement of shared decision-making and its consequences in healthcare practice. It aims to evaluate the crucial elements of shared decision-making particularly the factors that affect the voluntariness and informed consent in medical practice. This paper reviews the existing literature surrounding the phenomenon of shared decision-making for medical treatment in the healthcare, particularly giving importance to the patients’ views and how it plays a role in shared decision-making. This study provides an overview of the perplexing concept of shared decision-making and the various concerns that have surrounded the topic leading to its recognition. Hence in Malaysia, there is no specific law that governs the provisions for shared decision-making approach in the healthcare practice. This study aims to explore the Malaysian Medical Council Guideline on Consent for Treatment of Patients by Registered Medical Practitioner (MMC Guideline on Consent) and the current Malaysian laws to determine whether they are sufficient to address the element of informed consent requirement in shared decision. Finally, lack of empirical evidence is recognised in this paper and several suggestions are made for future research and recommendations for the enactment of new provisions pertaining to medical treatment.
