Early intravenous iron administration in the Emergency Department reduces red blood cell unit transfusion, hospitalisation, re-transfusion, length of stay and costs.

BACKGROUND: Moderate to severe iron deficiency anaemia is a common finding in patients admitted to the Emergency Department (ED). According to Patient Blood Management principles, intravenous iron should be the therapy of choice instead of blood transfusion for selected cases affected by chronic iron deficiency anaemia. However, this option is only rarely taken into account by physicians in the ED. As a result, in many circumstances, treatment of iron deficiency anaemia in the ED can differ from that of the Anaemia Clinic. With the aim of reducing inappropriate transfusions, and to implement intravenous iron usage, we shared a specific protocol with the ED. MATERIAL AND METHODS: We reviewed the medical records of all subjects admitted to the ED (n=267, Post-protocol group) with hemoglobin ≤9.0 g/dL and mean corpuscular volume <80 fL in a 13-month period, except if the massive transfusion protocol was activated, and results were compared with an equivalent Pre-protocol historical cohort (n=226). RESULTS: In comparison with the Pre-protocol series, the number of patients transfused did not change, but the appropriateness in terms of transfusion and red blood cell volume transfused improved sharply (87.0 vs 13.3%; p<0.001) with a significant increase in intravenous iron administration (50.2 vs 4.4% of cases; p<0.001). As a positive consequence, both the time spent in the ED by patients who were then directly discharged and costs per subject treated dropped by 37.9% and 59.0%, respectively. Treatment with infusion only in comparison with transfusion only led to a statistically significant Relative Risk reduction in transfusion on the ward and post-discharge transfusion of 55.6% and 44.4%, respectively. DISCUSSION: The implementation of Patient Blood Management principles and early intravenous iron therapy in the Emergency Department have proved to be effective tools to optimise resources both in terms of units transfused and costs.

Performance-based functional assessment in older hospitalized patients: feasibility and clinical correlates.

BACKGROUND: Functional evaluation is a cornerstone of multidimensional geriatric assessment; however, little is known of the clinical value of standardized performance-based assessment in the acute care setting. The aim of this study was to evaluate the clinical correlates and short-term predictive value of the Short Physical Performance Battery (SPPB) in older patients admitted to the hospital for an acute medical event. METHODS: We enrolled 92 women and men 65 years old or older who were able to walk, who had a Mini-Mental State Examination (MMSE) score > or =18, and who were admitted to the hospital with a clinical diagnosis of congestive heart failure, pneumonia, chronic obstructive pulmonary disease (COPD), or minor stroke. The SPPB was assessed at hospital admission and discharge. Self-report functional assessment included basic activities of daily living (ADL) and instrumental activities of daily living (IADL). Spearman's rank correlation coefficients and multivariable linear regression analyses were used to study the association of SPPB score and functional and clinical characteristics, including length of hospital stay. RESULTS: The mean age was 77.7 years (range 65-94 years), 49% were female, 64.1% had congestive heart failure, 16% COPD, 13.1% pneumonia, and 6.5% minor stroke. At hospital admission the mean SPPB score was 6.0 +/- 2.7. SPPB scores were inversely correlated with age, the severity of the index disease, and IADL and ADL difficulty 2 weeks before hospital admission (p <.01), and were directly correlated with MMSE score (p =.002). On average, SPPB score increased 1 point (+0.97, standard error of the mean = 0.2; p for paired t test <.001) from baseline to hospital discharge assessment. After adjustment for potential confounders, baseline SPPB score was significantly associated with the length of hospital stay (p <.007). CONCLUSION: In older acute care inpatients, SPPB is a valid indicator of functional and clinical status. SPPB score at hospital admission is an independent predictor of the length of hospital stay.

Risk factors for short-term mortality in older subjects with acute ischemic stroke.

BACKGROUND: Stroke is the third cause of death in older individuals living in Western Countries. The identification of predictors for mortality after stroke has a major importance for clinicians in order to allow the implementation of therapeutic and preventive strategies. OBJECTIVE: To evaluate the association between clinical and laboratory parameters and 30-days total mortality in a large sample of older patients with stroke. METHODS: 469 older patients (median age: 80.0 years) consecutively hospitalized for acute ischemic stroke were enrolled. The data recorded included: (1) clinical features of stroke; (2) routine clinical chemistry analyses; (3) medical history, and (4) 12-lead ECG. All patients underwent computed tomography scan of the brain. Stroke type was classified by the Oxfordshire Community Stroke Project system. RESULTS: 130 subjects died within 30 days after stroke, with an overall mortality of 27.7%. At univariate analysis, altered levels of consciousness (ALC), congestive heart failure, atrial fibrillation, previous stroke, high blood glucose, fibrinogen and blood sedimentation rate levels, higher white blood cell count, lower serum albumin and iron levels were associated with mortality. Multivariate logistic regression analysis indicated that short-term mortality was associated with ALC (OR: 11.80; CI 95%: 5.50-24.00), congestive heart failure (OR: 3.06; CI 95%: 1.04-8.80), and age (OR: 1.04; CI 95%: 1.002-1.09) independent of gender, previous stroke, AF, fasting blood glucose, serum albumin, serum iron, and white blood cell count. In patients with ALC (high-mortality rate: 63.6%), only hyperglycemia (III vs. I tertile, OR: 9.60; CI 95%: 1.65-52.50) was associated with mortality after multivariate adjustment. CONCLUSION: Our study highlights the role of ALC and congestive heart failure in the short-term prognostic stratification of older patients with acute ischemic stroke. Furthermore, our results support the value of post-stroke hyperglycemia as a marker for short-term mortality also in advanced age, and particularly in the presence of ALC and in nondiabetic individuals.

Anemia and cognitive performance in hospitalized older patients: results from the GIFA study.

BACKGROUND: Anemia represents a major risk factor for adverse health-related events in older persons. The aim of this study was to evaluate the association between hemoglobin levels/anemia and cognitive function in hospitalized older persons. METHOD: Data are from the Gruppo Italiano di Farmacovigilanza nell'Anziano (GIFA) study. Hemoglobin levels (in g/dL) were measured upon admission to hospital; anemia was defined according to the WHO criteria. Cognitive performance was assessed by the Abbreviated Mental Test (AMT) on admission; an AMT score <7 defined cognitive impairment. Logistic regressions and analyses of covariance were performed to evaluate the relationship between cognitive status and hemoglobin levels/anemia. RESULTS: Mean age of the sample (n = 13,301) was 72.0 years. Participants with cognitive impairment presented a higher prevalence of anemia (47%) compared to those without cognitive impairment (35%, p < 0.001). Adjusted logistic regressions showed that hemoglobin levels/anemia were significantly associated with cognitive impairment (OR = 0.96, 95%CI = 0.94-0.99, p = 0.004, and OR = 1.32, 95%CI = 1.18-1.48, p < 0.001, respectively). Patients with anemia and cognitive impairment at the hospital admission presented a higher number of impaired Activities of Daily Living compared to those with only one or none of the studied conditions (p for trend < 0.001). CONCLUSION: Low hemoglobin levels and anemia are independently associated with cognitive performance in older persons admitted to acute care units.

Prescription of antithrombotic therapy in older patients hospitalized for transient ischemic attack and ischemic stroke: the GIFA study.

BACKGROUND AND PURPOSE: Antithrombotic therapy has been demonstrated as an effective tool for secondary ischemic stroke prevention. Nevertheless, scant data are available on actual prescription of this therapy in clinical practice. METHODS: A total of 17 337 patients admitted to geriatric and internal medicine wards participating in the study in the 1993 to 1998 survey period were analyzed. Patients with coded diagnoses of ischemic stroke and transient ischemic attack (TIA) were selected. Data recorded included demographic and clinical characteristics and medication prescription during hospital stay and at discharge. Logistic regression analyses were used to identify conditions associated with the prescription of antiplatelet or anticoagulant drugs. RESULTS: Among 946 patients with diagnosis of stroke or TIA (mean age 78 years), >40% was discharged without antithrombotic prescription. Conditions that made the prescription more unlikely were diagnosis of stroke (odds ratio [OR]: 0.61; 95% confidence interval [CI]: 0.44 to 0.86), presence of anemia (OR: 0.70; 95% CI: 0.49 to 0.98), severe disability (OR: 0.48; 95% CI: 0.30 to 0.75), and cognitive impairment (OR: 0.58; 95% CI: 0.43 to 0.75). There was an independent and additive association of physical and cognitive status with antithrombotic therapy prescription. CONCLUSIONS: A high rate of patients affected by stroke or TIA are discharged from the hospital without antithrombotic therapy. The most important correlates of the likelihood of not receiving an antithrombotic medication were cognitive and functional status.

Comparison of magnesium concentration in serum, erythrocytes and gastric tissue in two groups of patients affected by chronic gastritis, Helicobacter pylori negative and positive.

UNLABELLED: Magnesium seems to be an important factor both for acid gastric secretion regulation (together with Ca2+) and for Helicobacter pylori survival and virulence. It can therefore be useful to evaluate if Helicobacter pylori (HP) infection is accompanied by variations in the host Mg availability. In this study serum, erythrocytary and gastric tissue Mg concentration was measured in 36 patients affected by chronic antral gastritis. Based on the presence of Helicobacter pylori infection, the patients were subdivided in two groups: group A: Helicobacter pylori negative, n = 23; group B: Helicobacter pylori positive, n = 13. RESULTS: While no differences were found between the two groups for serum Mg (group A 0.81 +/- 0.07 mm/L, group B 0.81 +/- 0.11 mm/L), both erythrocytary Mg (EMg) and gastric tissue Mg were found significantly lower in the HP positive subjects (erythrocytary Mg: 2.14 +/- 0.55 vs. 1.81 +/- 0.34 mm/L; gastric tissue Mg: 729.2 +/- 333.8 vs. 510.6 +/- 178.8 microg/g of dried tissue for group A and B respectively, p < 0.001 for both determinations). Erythrocytary Mg reduction is a clue of the whole body reduction in Mg availability (and consequently in gastric cells as well); the erythrocytary Mg reduction detected in the present paper for Helicobacter pylori positive patients can weaken gastric cells by impairing their metabolism. The hypothesis submitted is to impair Mg utilization in Helicobacter pylori, in order to improve eradication treatment, and in the meantime to preserve Mg homeostasis in infected cells.
