Magnitude of Anemia at Discharge Increases 30-Day Hospital Readmissions

Background Anemia during hospitalization is associated with poor health outcomes. Does anemia at discharge place patients at risk for hospital readmission within 30 days of discharge? Our objectives were to examine the prevalence and magnitude of anemia at hospital discharge and determine whether anemia at discharge was associated with 30-day readmissions among a cohort of hospitalizations in a single health care system. Methods From January 1, 2009, to August 31, 2011, there were 152,757 eligible hospitalizations within a single health care system. The endpoint was any hospitalization within 30 days of discharge. The University HealthSystem Consortium's clinical database was used for demographics and comorbidities; hemoglobin values are from the hospitals' electronic medical records, and readmission status was obtained from the University HealthSystem Consortium administrative data systems. Mild anemia was defined as hemoglobin of greater than 11 to less than 12 g/dl in women and greater than 11 to less than 13 g/dl in men; moderate, greater than 9 to less than or equal to 11 g/dl; and severe, less than or equal to 9 g/dl. Logistic regression was used to assess the association of anemia and 30-day readmissions adjusted for demographics, comorbidity, and hospitalization type. Results Among 152,757 hospitalizations, 72% of patients were discharged with anemia: 31,903 (21%), mild; 52,971 (35%), moderate; and 25,522 (17%), severe. Discharge anemia was associated with sev...

Authors: Betul Ergul A, Turanoglu C, Karakukcu C, Guler Kazanci E, Altuner Torun Y Abstract Additional nutritional deficiencies may accompany zinc deficiency. We determined the vitamin B12 levels in patients with zinc (Zn) deficiency. This retrospective study enrolled 256 patients age 6 months to 16 years (176 females and 80 males) in whom Zn levels in hair samples were measured concurrently with serum vitamin B12 and ferritin levels. For all patients, we retrospectively assessed the hair Zn levels, serum ferritin and vitamin B12 levels, red blood cell count, hemoglobin, hematocrit, mean corpuscular volume, mean co...

Authors: Gou SJ, Yu SB, Qiu HY, Hu ZX Abstract Awareness of the uncommon associated clinical manifestations of immunoglobulin G4 (IgG4)-related kidney disease is essential for the early diagnosis and effective treatment of patients. To the best of our knowledge, there have been few reports of patients with IgG4-related kidney disease associated with autoimmune hemolytic anemia. We here report a rare case of IgG4-related kidney disease associated with autoimmune hemolytic anemia. A 70-year-old man with kidney dysfunction and severe anemia had been diagnosed with chronic kidney disease and treated without any improve...

Authors: Yari Z, Mirmiran P Abstract Chronic kidney disease is defined as a glomerular filtration rate lower than 60 mL/min/1.73 m2, which is regarded as a public health priority and part of the growing burden of noncommunicable diseases. Reduced kidney function is concomitant with high levels of inflammatory factors, abnormal lipid profile, and anemia, as well as bone abnormalities, calcium deposition outside the bones, endothelial dysfunction, and cardiomyopathy. Furthermore, metabolic acidosis is a common complication in chronic kidney disease that is associated with secondary hyperparathyroidism and faster kidn...

We report two children with systemic lupus erythematosus (SLE) having severe bleeding manifestations and lupus anticoagulant hypoprothrombinemia syndrome (LAHPS) along with a review of published cases of childhood SLE and LAHPS. We report clinical and laboratory profile of two children diagnosed with childhood SLE and LAHPS. We also conducted literature search to identify similar published cases and a review was performed. An 8-year-old girl had presented with fever, arthralgia, alopecia, anasarca and bleeding from multiple sites. She was diagnosed to have SLE based on laboratory investigations which showed anemia, thrombo...

This study retrospectively reviewed the medical records of non-anemic pregnant women who received first antenatal care at the Department of Obstetrics and Gynecology, Faculty of Medicine Vajira Hospital, Navamindradhiraj University, Bangkok, Thailand, during the June 2009 –December 2010 study period. All included women had blood pressure and urine albumin level data that were recorded at each antenatal visit. The study population was divided into one of the two following groups: iron supplementation starting at gestational age (GA)

CONCLUSIONS: In summary, increasing age, female sex, anemia, and presence of PVD are risk factors for cognitive impairment in PD patients. Self-care PD with cognitive impairment at 1 year has a higher risk for PD-related peritonitis in the second year. Interval HK-MoCA assessment is recommended to detect cognitive impairment in our local PD patients. PMID: 30087176 [PubMed - as supplied by publisher]
