Sickle Cell Health Awareness, Perspectives, and Experiences (SHAPE) Survey: Perspectives of Physicians in Gulf Cooperation Council Countries on Sickle Cell Disease

Introduction: Sickle cell disease (SCD) is a genetic disorder that adversely impacts patients' physical and emotional well-being, yet research on the impact of SCD on quality of life is limited. The prevalence of SCD across Gulf Cooperation Council (GCC) countries ranges 0.24-5.8% (Abu-Shaheen et al. Expert Rev Hematol 2022). The Sickle Cell Health Awareness, Perspectives, and Experiences (SHAPE) survey aimed to broaden understanding of the global burden of SCD. This analysis reports the experiences of physicians in GCC countries treating patients with SCD who participated in the SHAPE survey within the context of insights obtained globally.

Methods: Physicians from Brazil, Canada, France, Germany, the UK, the US, and 2 countries in the GCC (Saudi Arabia and the United Arab Emirates [UAE]) completed a 12-minute online survey comprising close-ended questions about their experiences of treating patients with SCD. Physicians practicing for 3-35 years and currently caring for ≥10 patients with SCD were eligible.

Results:Of 219 physicians globally who responded, 30 (13.7%; Saudi Arabia and the UAE, n=15 each) were from GCC countries. Physicians in GCC countries on average were caring for 16 patients with SCD and had 16 years of experience treating patients with SCD. The most common symptoms of SCD reported to physicians in GCC countries were bone aches (95%) in patients aged ≤11 years, fatigue/tiredness and bone aches (92% each) in patients aged 12-17 years, and bone aches (100%) in patients aged ≥18 years. Bone aches and yellow eyes/skin/nails were symptoms reported by a significantly higher proportion of patients in all age groups to physicians in GCC countries than all surveyed physicians (Figure 1). Most physicians agreed early treatment of SCD can help with managing/preventing severe symptoms (80% in GCC countries vs 87% globally) and that treating hemolytic anemia can improve most aspects of SCD including, reducing end-organ damage (87% vs 84%). A significantly greater proportion of physicians in GCC countries, compared with all surveyed physicians, reported they were confident in their knowledge of the consequences of hemolytic anemia (93% vs 50%), and they were significantly more likely to attribute the development of SCD complications such as chronic anemia, kidney damage, and blood clots to hemolytic anemia (Figure 2). A significantly greater proportion of physicians in GCC countries, compared with all surveyed physicians, agreed end-organ damage is unavoidable (87% vs 59%), and they were reluctant to discuss the potential future challenges/complications of SCD with a patient or their family (57% vs 37%). Most physicians agreed they were optimistic about future treatments for SCD (73% in GCC countries vs 81% globally). A significantly greater proportion of physicians in GCC countries reported considering the cost/benefit ratio to the patient and/or health care system before recommending a treatment compared with all surveyed physicians (87% vs 64%). Physicians in GCC countries, compared with all surveyed physicians, reported a significantly smaller proportion of patients were treated with hydroxyurea (24% vs 43%) and opioids (10% vs 29%). The top concerns physicians in GCC countries had were their patients not understanding the long-term effects/progression of SCD (47%), only seeking treatment/care when experiencing crises (47%), and lack of community support for patients (40%). Physicians reported wanting more support to educate their patients about the long-term effects of SCD (93% in GCC countries vs 83% globally).

Conclusions: Physicians in GCC countries identified the symptom(s) most frequently reported by patients aged ≤11 years and ≥18 years as bone aches, and by patients aged 12-17 years as bone aches and fatigue/tiredness. Most physicians in GCC countries agreed end-organ damage is unavoidable, but over half were reluctant to discuss the potential future complications of SCD with patients and their families. Findings from the SHAPE survey underline the need for treatments that target specific SCD symptoms and delay end-organ damage, as well as the need of physicians in GCC countries for greater support when treating patients with SCD.
