This scoping review aims to identify and summarize existing evidence concerning the quality and capacity of PHC services in the Kingdom of Saudi Arabia (KSA) with a focus on the patients and healthcare professionals' perceptions of PHC. Methods: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The digital library, PubMed, and the search engine Google Scholar were searched to broaden our results for primary research involving patient and/or health professionals' perspectives on Primary Healthcare in KSA. Results: A total of 38 publications were selected for the scoping review. Several studies examined patients' overall satisfaction with PHC services (n=14) while others focused their investigation on specific services provided by PHC (n=3). Several studies assessed the perceptions of certain groups of patients (n=5). Several studies examined health professionals' perceptions of the use of electronic health records (n=3), the safety culture (n=2), communicable disease management (n=1), emergency services (n=1), laboratory services (n=1), cost-effectiveness (n=1), and leadership (n=1). This review also included studies that assessed the health professionals' job satisfaction and burnout (n=6). Conclusion: Patients were satisfied with some aspects of PHC services while recognizing that improvements in some areas were needed. These included waiting time, physician-patient communication, access to the services in rural areas, patient involvement in disease management, and oral health. Health workers were positive about certain quality aspects and services provided by PHC such as EHRs, safety culture, communicable disease management, emergency services, and laboratory services. Health workers demonstrated a low level of job satisfaction due to several reasons, including, working conditions, financial incentives, and burnout.
