Background: Information on how the execution of primary health care towards addressing noncommunicable diseases to bring about desired health outcomes have been limited. Hence, this study Aims to determine the experiences in implementing a primary health care approach to address noncommunicable diseases based from the perspectives of various concerned health workers at the primary care level. Methods: A qualitative case study approach was employed using data from 16 focus groups Discussions 68 primary care workers. A semi-structured interview was utilized to determine perceptions and experiences in  implementation of primary health care approach to address noncommunicable diseases in selected care facilities from all cities and municipalities in one province in the Philippines. All interviews were audio-recorded and transcribed verbatim. An inductive content analysis using NVivo 12 was employed to distinguish and classify relevant thematic codes. Results: An inclusive delivery of primary health care approach through health education and promotion, assessment and monitoring of patients, patient treatment and management, and collaboration among health workers and care institutions were implemented. This Resultsed to an efficacious patient health outcome such as increased health knowledge and awareness, prevention of diseases or untoward progression, and better patient satisfaction.  Enablers of primary health care implementation to address noncommunicable diseases include the following: (1) supportive leadership and governance; (2) dedicated and competent healthcare workers; (3) prioritization of noncommunicable diseases; (4) functional referral mechanism; and (5) efficient utilization of limited resources. However, noncommunicable disease service delivery was overshadowed by: (1) health human resource constraints; (2) logistical inadequacies; (3) limited access and availability of services and facility; (4) patient issues and impediments; and (5) structural restrictions. Conclusions: Primary care workers argued a robust delivery of primary health care approaches to confront noncommunicable diseases positively enhancing patient health.  However, its implementation is determined by concurrence of various facilitating and hindering factors.
