i Effects of the Integrated Concentration-Meditation Care Program on Anxiety, Self-Breathing Control, and Weaning Outcomes in Patients with Difficult Weaning from Mechanical Ventilation: A Multi-Site Study Benjamard Thinhuatoey A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Nursing (International Program) Prince of Songkla University 2015 Copyright of Prince of Songkla University ii iii iv v ACKNOWLEDGEMENTS In recognition of my successful study, my deepest appreciation and thanks to Assoc. Prof. Dr. Praneed Songwathana, major advisor and Asst. Prof. Dr. Wongchan Petpichetchian, co-advisor; for their kindness and patience they have shown me. It has been a long journey. Due to the challenge of conducting smart nursing research, a good opportunity was referred upon me in which the Graduate School, Prince of Songkla University, gave me the visiting scholarship to conduct the research for this thesis. I had a valuable experience to work with Prof. Dr. Leanne Aitken and her research team at Nursing Faculty, Griffith University and Princess Alexandra Hospital, Nursing Practice Development Unit, Princess Alexandra Hospital, Australia. My grateful thanks are also given to all my teachers who have taught me and implanted in me to apply nursing philosophy and nursing theory into nursing practice. My grateful appreciation is extended to the dissertation committee. In a perspective vision of human resource development, I greatly appreciated Khun Tareetip Nuntarakchikul who was the Head Nurse of Surat thani Hospital at that moment in supporting me to be the Doctor of Philosophy in Nursing. I wish to acknowledge the director of Surat thani Hospital, Head Nurse, ICU Nurse Supervisor, Head of Medical-ICU for permission of granting leave for study. The biggest appreciation is given to my lovely parents who have always supported me in any situation. I cannot ignore to refer my heartfelt thanks to the ICU vi patients, their caregivers, and ICU nurses from Surat Thani Hospital, Maharat Nakorn Si Thamarat Hospital, and Songkhla Hospital; who participated in exploring the knowledge related to using the ICMCP in enhancing weaning success for difficult weaning from mechanical ventilation. Thanks are also given to my PhD friends for sharing their knowledge. Additional thanks are given to one special ICU patient, Mr. Allan Read and his family who have helped me in improving my academic writing.
