Background: Objective and key results (OKRs) was a strategic tool to drive the organization to achieve a goal. Goals are concomitant and come from leaders and personnel. Most hospital management studies are conducted in a qualitative approach. Objective: To evaluate the association of knowledge, attitudes, practices, personal factor (PF), and perceived organizational support (POS) of OKRs in quantitative approach. Materials and Methods: The present study was a descriptive study conducted at Thammasat University Hospital (TUH), Pathum Thani, Thailand between March and April 2024. Participants were TUH personnel. Self-filling questionnaires were applied and signed written informed consent after thoroughly counselled. Questionnaires consisted of POS, knowledge, attitudes, and practices questions. PF was also collected. Results: Two hundred and twenty-one participants were recruited. Most participant (192 out of 221) were female. Three-quarters (149 out of 221) of the participants had more than ten years’ experience. Eighty-six percent (192 out of 221) of the participants had an educational level equal to or higher than bachelor. Mean knowledge, attitudes, and practices of participants were 9.5±0.6, 3.9±0.4, and 3.7±0.4, respectively. PF was not associated with POS and practices. Hospital personnel with more than 20 years seniority had OKRs’ knowledge less than those less than 10 years seniority (b= –0.21, p=0.04). Monthly income and work experience were significantly positive and negative associated with attitudes at b=0.17 and –0.15, respectively. POS was not associated with attitudes and knowledge. Practice was associated with POS, with statistical significance (b=0.20, p<0.001). Conclusion: OKRs knowledge decreased with work experience. Attitude was associated with high monthly income and reverse associated with work experience. POS was significantly associated with the practice. There was no association between PF and practice, PF and POS, POS and attitude, and POS and knowledge. This study provided guidelines for recognizing organizational support in implementing OKRs and improving processes to ensure efficiency and staff involvement. Management should establish clear policies involving personnel at all levels.
