Exploring the Challenges Faced by Primary Care Physicians in Providing Optimal Care for Patients With Hypertension: A Qualitative Study

Background: Globally, most patients with hypertension have suboptimal blood pressure (BP) control. Multiple barriers prevent primary care physicians (PCPs) from effectively caring for these patients. This study aimed to explore the challenges faced by PCPs in providing optimal care for patients with hypertension, with a specific focus on identifying new barriers.Methods: This qualitative study involved 17 PCPs across 5 primary care clinics in Singapore. A trained researcher conducted individual in-depth interviews using a topic guide. Purposive sampling was employed to ensure adequate representation of seniority until data saturation was achieved. The audio-recorded interviews were transcribed verbatim and independently checked. The data were managed using NVivo and thematic analysis was conducted.Results: New barriers were divided into patient, physician, drug, and systemrelated factors. Patient factors included a preference for natural health remedies and the inconvenience of blood tests. Meanwhile, physicians faced challenges diagnosing and treating patients with various BP phenotypes and BP variability. The initiation of dual therapy was a drugrelated barrier. Finally, system factors included the suboptimal layout of the electronic medical records (EMR) that impeded effective hypertension management.Conclusion: A multi-pronged approach is required to address the significant barriers to providing optimal hypertension care. Patients should be empowered through education and minimizing the inconvenience of medication titrations. Additionally, physicians should be better equipped to diagnose and treat patients with more challenging BP phenotypes. Finally, improved access to combination pills and an optimized EMR would contribute to improved care for patients with hypertension.
