Abstract
Sterile Injectable Products (SIPs) represent a critical class of pharmaceuticals that frequently face shortages and ultimately compromise patient care. Disruptions within the pharmaceutical supply chain are significant factors contributing to these shortages. This study aimed to investigate the causes and impacts of SIPs shortages in Saudi Arabia, with the central hypothesis that pharmaceutical supply chain disruptions are the primary drivers of these shortages and that they negatively affect patient outcomes. A cross-sectional questionnaire was administered to two key stakeholder groups: supply chain management (SCM) personnel and healthcare professionals (HCPs). A total of 350 responses were collected and statistically analyzed. Our findings demonstrate a strong consensus among SCM respondents, with 73% agreeing that supply chain disruptions significantly affect SIPs availability. Poor demand forecasting and limited sourcing capabilities were identified as the primary contributing factors. From the perspective of HCPs, over 65% indicated that SIP shortages adversely impacted patient care, resulting in treatment delays, extended hospital stays, and increased healthcare costs. Additionally, many respondents reported that staff time is often wasted in the search for alternative therapies, which may also be of short supply. Interestingly, more than 70% of respondents from both groups expressed robust support for the adoption of advanced technologies such as artificial intelligence (AI) and machine learning (ML) to enhance forecasting and inventory management. Taken together, these findings underscore the urgent need for integrated strategies including proactive forecasting, sustainable inventory management, expanded local manufacturing, and AI-driven tools to strengthen the resilience of the SIP supply chain in Saudi Arabia and beyond.
