Artificial intelligence-assisted identification and retrieval of chronic hepatitis C patients lost to follow-up in the health area of Pontevedra and O Salnés (Spain).

OBJECTIVE: Direct-acting antivirals (DAAs) to treat hepatitis C virus (HCV) infection offer an opportunity to eliminate the disease. This study aimed to identify and relink to care HCV patients previously lost to medical follow-up in the health area of Pontevedra and O Salnés (Spain) using an artificial intelligence-assisted system. PATIENTS AND METHODS: Active retrospective search of previously diagnosed HCV cases recorded in the Galician Health Service proprietary health information exchange database using the Herramientas para la EXplotación de la INformación (HEXIN) application. RESULTS AND CONCLUSIONS: Out of 99 lost patients identified, 64 (64.6%) were retrieved. Of these, 62 (96.88%) initiated DAA treatment and 54 patients (87.1%) achieved a sustained virological response. Mean time from HCV diagnosis was over 10 years. Main reasons for loss to follow-up were fear of possible adverse effects of treatment (30%) and mobility impediments (21%). Among the retrieved patients, almost one in three presented advanced liver fibrosis (F3) or cirrhosis (F4) at evaluation. In sum, HCV patients lost to follow-up can be retrieved by screening past laboratory records. This strategy promotes the achievement of HCV elimination goals.

Adherence to patient blood management strategy in patients with gastrointestinal bleeding: a prospective nationwide multicenter study.

INTRODUCTION: Patient blood management (PBM) adherence in clinical practice is unclear. This real-world practice study assessed the management of patients with gastrointestinal (GI) bleeding after the implementation of the PBM strategy. METHODS: This was a nationwide multicenter and prospective study involving consecutive adults with GI bleeding between March 2019 and March 2021. Patients were examined according to hemoglobin (Hb) level at admission (<7 g/dl, n = 93; 7-8 g/dl, n = 47; 8-9 g/dl, n = 61; and >9 g/dl, n = 249). Study outcomes measures were morbidity and mortality during hospitalization and at 3- and 6-month follow-up. Appropriate anemia or iron deficiency management was considered when adherence to PBM policy was higher than 75%. RESULTS: A total of 450 patients (57.6% men, median age: 74 years, interquartile range: 63-82) were included. Overall, 55.1% and 59.3% of patients received transfusion and iron supplementation, respectively. The rates of appropriate transfusion and iron supplementation adherence were 90.9% (range: 86.9-93.5%, P = 0.109) and 81.8% (range: 78.5-85.1%, P = 0.041), depending on Hb level, respectively. No associations were observed between adherence to the PBM strategy and length of stay (P = 0.263) or risk of further bleeding (P = 0.742). Patients who were transfused [hazard ratio (HR): 0.79, 95% confidence interval (CI): 0.27-0.85] and iron supplemented (HR: 0.91, 95% CI: 0.38-1.41), however, appropriately achieved a lower risk of death. Age (HR: 1.12, 95% CI: 1.12-1.25) and further bleeding (HR: 39.08, 95% CI: 4.01-181.24) were poor prognostic factors. No serious adverse events were reported. CONCLUSIONS: In this nationwide study, there is a high level of adherence and safety of PBM for the treatment of GI bleeding. Adherence to the PBM strategy improved outcomes in patients with GI bleeding.

Heart failure with recovered ejection fraction: Clinical characteristics, determinants and prognosis. CARDIOCHUS-CHOP registry.

BACKGROUND: The magnitude and the prognostic impact of recovering left ventricular ejection fraction (LVEF) in patients with heart failure (HF) and systolic dysfunction is unclear. The aim of this study was to evaluate the clinical characteristics and prognosis of patients with HFrecEF in an HF population. METHODS: 449 consecutive patients were selected with the diagnosis of HF and an evaluation of LVEF in the 6 months prior to selection who were referred to two HF units. Patients with systolic dysfunction were only considered if a second echocardiogram was performed during the follow-up. RESULTS: At the time of diagnosis, 207 patients had LVEF > 40% (HFpEF) and 242 had LVEF ≤ 40% (HFrEF). After 1 year, the LVEF was re-evaluated in all 242 patients with a LVEF ≤ 40%: in 126 (52%), the second LVEF was > 40% (HFrecEF), and the remaining 116 (48%) had LVEF ≤ 40% (HFrEF). After 1800 ± 900 days of follow-up patients with recovered LVEF had a significantly lower mortality rate (HFpEF vs. HFrecEF: hazard ratio [HR] = 2.286, 95% confidence interval [95% CI] 1.264-4.145, p = 0.019; HFrEF vs. HFrecEF: HR = 2.222, 95% CI 1.189-4.186, p < 0.001) and hospitalization rate (HFpEF vs. HFrecEF: HR = 1.411, 95% CI 1.046-1.903, p = 0.024; HFrEF vs. HFrecEF: HR = 1.388, 95% CI 1.002-1.924, p = 0.049). The following are predictors of LVEF recovery: younger age, lower functional class, treatment with renin-angiotensin-aldosterone system inhibitors and beta-blockers, absence of defibrillator use, and non-ischemic etiology. CONCLUSIONS: Patients with HF and reduced LVEF who were re-evaluated after 1 year, had significant improvement in their LVEF and had a more favourable prognosis than HF with preserved and reduced ejection fraction.
