Why differentiating between health system support and health system strengthening is needed.

There is increasing recognition that efforts to improve global health cannot be achieved without stronger health systems. Interpretation of health system strengthening (HSS) has varied widely however, with much of the focus to-date on alleviating input constraints, whereas less attention has been given to other performance drivers. It is important to distinguish activities that support the health system, from ones that strengthen the health system. Supporting the health system can include any activity that improves services, from distributing mosquito nets to procuring medicines. These activities improve outcomes primarily by increasing inputs. Strengthening the health system is accomplished by more comprehensive changes to performance drivers such as policies and regulations, organizational structures, and relationships across the health system to motivate changes in behavior and/or allow more effective use of resources to improve multiple health services. Even organizations that have made significant investments in health systems have not provided guidance on what HSS entails. While both supporting and strengthening are important and necessary, it is nonetheless important to make a distinction. If activities fail to produce improvements in system performance because they were incorrectly labeled as system strengthening, the value of HSS investments could quickly be discredited. Not distinguishing supportive activities from strengthening ones will lead to unmet expectations of stronger health systems, as well as neglect of critical system strengthening activities. Distinguishing between these two types of activities will improve programming impact.

PEPFAR, health system strengthening, and promoting sustainability and country ownership.

Evidence demonstrates that scale-up of HIV services has produced stronger health systems and, conversely, that stronger health systems were critical to the success of the HIV scale-up. Increased access to and effectiveness of HIV treatment and care programs, attention to long-term sustainability, and recognition of the importance of national governance, and country ownership of HIV programs have resulted in an increased focus on structures that compromise the broader health system. Based on a review published literature and expert opinion, the article proposes 4 key health systems strengthening issues as a means to promote sustainability and country ownership of President's Emergency Plan for AIDS Relief and other global health initiatives. First, development partners need provide capacity building support and to recognize and align resources with national government health strategies and operational plans. Second, investments in human capital, particularly human resources for health, need to be guided by national institutions and supported to ensure the training and retention of skilled, qualified, and relevant health care providers. Third, a range of financing strategies, both new resources and improved efficiencies, need to be pursued as a means to create more fiscal space to ensure sustainable and self-reliant systems. Finally, service delivery models must adjust to recent advancements in areas of HIV prevention and treatment and aim to establish evidence-based delivery models to reduce HIV transmission rates and the overall burden of disease. The article concludes that there needs to be ongoing efforts to identify and implement strategic health systems strengthening interventions and address the inherent tension and debate over investments in health systems.
