How Would You Treat This Patient With Acute and Chronic Pain From Sickle Cell Disease? : Grand Rounds Discussion From Beth Israel Deaconess Medical Center.

Sickle cell disease is prevalent in large numbers of patients in the United States and has a significant global impact. Its complications span numerous organs and lead to reduced life expectancy. Acute and chronic sickle cell pain is a common cause of patient suffering. The American Society of Hematology published updated guidelines on management of acute and chronic pain from sickle cell disease in 2019. Several of the recommendations are conditional and leave specific decisions to the treating physician. These include conditional recommendations about the use of ketamine for acute pain and the initiation and discontinuation of long-term opioid therapy for chronic pain. Here, 2 hematologists discuss these guidelines and make contrasting recommendations for the management of acute and chronic pain for a patient with sickle cell disease.

Development of a Hematology-General Medicine Hybrid Team to Improve Care of Patients With Sickle Cell Disease.

PROBLEM: Approximately 100,000 individuals in the United States have sickle cell disease (SCD). These individuals face multiple barriers to equitable care. At Brigham and Women's Hospital, existing health inequities for these patients were compounded by admitting, rounding, and team structures that assigned patients with SCD to multiple medicine teams with a hematologist attending, leading to delays in patient care and gaps in residents' hematology knowledge. APPROACH: A hematology-general medicine hybrid team was created in September 2021 to enhance trainee knowledge, skill, and confidence in managing hematology conditions and improve the quality of care delivered to individuals with SCD. This allowed for regionalization of patients with classical hematology conditions to specific hospital floors under the care of one team with a hematologist as the attending of record. OUTCOMES: From October 1, 2021, to January 11, 2022, the majority (745/824, 90%) of in-hospital days for patients with a primary hematology diagnosis were under the care of the hematology-general medicine hybrid team. Regionalization to the home floor of the hybrid team was achieved on 331 (40%) of these 824 hospital days, consistent with regionalization rates for other teams. From October 1, 2021, to September 30, 2022, there were 128 unique patients with SCD admitted over 511 encounters and cared for by approximately 78 residents and 12 medical students. Feedback from residents reported improved knowledge in the management of hematology conditions, especially SCD. NEXT STEPS: The authors are working on a comprehensive analysis of the hybrid team's impact on trainee skill and confidence in managing SCD. The authors believe that this model can be replicated at other institutions to optimize trainee education, consolidate care, and address implicit bias against patients with SCD, even with the hematology attending as a consultant instead of as the attending of record.

The burden of hospital-acquired infections (HAI) in sub-Saharan Africa: a systematic review and meta-analysis.

Background: Hospital-acquired infections (HAI) are a leading cause of morbidity and mortality globally. These infections are diverse, but the majority are lower respiratory tract infection (LRTI), surgical site infection (SSI), bloodstream infection (BSI), and urinary tract infection (UTI). For most sub-Saharan African countries, studies revealing the burden and impact of HAI are scarce, and few systematic reviews and meta-analysis have been attempted. We sought to fill this gap by reporting recent trends in HAI in sub-Saharan Africa (SSA) with attention to key patient populations, geographic variation, and associated mortality. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a literature search of six electronic databases (Web of Science, Pubmed, APA PsycInfo, CINAHL, Embase, and the Cochrane Library) to identify studies assessing the prevalence of HAI in SSA countries. Studies published between 01 January 2014 and 31 December 2023 were included. We applied no language or publication restrictions. Record screening and data extractions were independently conducted by teams of two or more reviewers. Using the R software (version 4.3.1) meta and metafor packages, we calculated the pooled prevalence estimates from random-effect meta-analysis, and further explored sources of heterogeneity through subgroup analyses and meta-regression. This study is registered with PROSPERO, CRD42023433271. Findings: Forty-one relevant studies were identified for analysis, consisting of 15 from West Africa (n = 2107), 12 from Southern Africa (n = 2963), 11 from East Africa (n = 2142), and 3 from Central Africa (n = 124). A total of 59.4% of the patient population were associated with paediatric admissions. The pooled prevalence of HAI was estimated at 12.9% (95% CI: 8.9-17.4; n = 7336; number of included estimates [k] = 41, p < 0.001). By subregions, the pooled current prevalence of HAI in the West Africa, Southern Africa, East Africa and Central Africa were estimated at 15.5% (95% CI: 8.3-24.4; n = 2107; k = 15), 6.5% (95% CI: 3.3-10.7; n = 2963; k = 12), 19.7% (95% CI: 10.8-30.5; n = 2142; k = 11) and 10.3% (95% CI: 1.1-27.0; n = 124; k = 3) of the patient populations respectively. We estimated mortality resulting from HAI in SSA at 22.2% (95% CI: 14.2-31.4; n = 1118; k = 9). Interpretation: Our estimates reveal a high burden of HAI in SSA with significant heterogeneity between regions. Variations in HAI distribution highlight the need for infection prevention and surveillance strategies specifically tailored to enhance prevention and management with special focus on West and East Africa, as part of the broader global control effort. Funding: No funding was received for this study.

Anemia for the Primary Care Physician.

Anemia denotes a reduced red blood cell (RBC) mass from any cause. The causes of anemia are numerous and due to decreased (or abnormal) erythropoesis, shortened RBC life span, or blood loss. The most common etiology of anemia is iron deficiency. A judicious work up of anemia includes evaluating the reticulocyte count and peripheral smear. The severity of illness of a patient with anemia is determined by the degree of anemia and the seriousness of the underlying disorder. Management of patients with hereditary and hemolytic anemias should involve a hematologist.
