Summary Depression, disrupted sleep and pain are common comorbidities in sickle cell disease. We tested (1) if these comorbidities are associated with attention/executive functioning, processing speed and instrumental activities of daily living (IADLs), which describe complex skills that support independence, and (2) if cognitive symptoms mediate the relationship between comorbidities and IADLs. Participants (n = 2417) completed patient‐reported outcome measures through the Sickle Cell Disease Implementation Consortium. Mean age of participants was 28 years and HbSS/Sβ0 genotypes were prevalent (73%). Comorbidities of depression, pain frequency and disrupted sleep were associated with processing speed and attention/executive functioning (all p < 0.01) when controlling for stroke and demographics. IADLs were associated with depression, pain, sleep, attention/executive functioning, income (<$25 000) (all p < 0.001) and genotype (p = 0.0025) after controlling for covariates. The indirect effects of attention/executive functioning and processing speed were both significant (p < 0.001) in mediation models that examined pathways between comorbidities and IADLs. Attention/executive functioning accounted for 17.5% of the relationship between depression and IADLs and sleep and IADLs. Processing speed explained 10% of the relationship between sleep and IADLs and 8% of the relationship between depression and IADLs. Managing comorbidities should be prioritized to mitigate cognitive symptoms and improve complex daily living skills. [ABSTRACT FROM AUTHOR]

Acute and chronic pain are the most frequent complications of sickle cell disease (SCD), often severely reducing quality of life and requiring management with long-term pharmacological interventions. A biopsychosocial approach conceptualizing pain in SCD as the result of complex biological, psychological, and social factors could facilitate targeted behavioral interventions. Mindfulness is one procedure for management of pain in individuals with chronic pain/illness. The goal of the current project was to design and implement a bedside mindfulness intervention to help patients with SCD enhance self-efficacy of pain management and reduce distress. As part of a quality improvement project in SCD clinics in a large health system, we developed a bedside mindfulness intervention to be provided during infusion sessions for patients presenting for acute vaso-occlusive episodes (VOE). The approach to development and implementation involved engagement of professionals working directly with patients. Concept planning meetings with these professionals along with qualitative patient and provider feedback informed feasibility, design, and intervention application. During a quantitative phase, patients completed validated surveys items on acceptability. Interview data (N = 11) supported patient interest in mindfulness skills and highlighted a need for tailored, person-centered interventions and non-pharmacological treatment strategies. On quantitative items, participants (N = 14) liked the intervention and agreed mindfulness skills would help manage disease-related distress. Following the interventions, participants reported increased mindfulness (p = .005). While preliminary, these results provide support for the continued development of evidence-based, mindfulness-oriented services to help individuals with SCD manage pain and other psychological difficulties.
