"Vitamin C Deficiency in Hospitalized Adults: Systematic Screening Vs. Traditional Judgment - a Before-and-After Observational Study"

Sponsor: Internist.Ro

Summary

Brief Summary of the Study The goal of this observational study is to assess the incidence of vitamin C deficiency among hospitalized adults presenting with hemorrhagic signs. The study will also evaluate the effectiveness of a standardized screening protocol compared to traditional clinical judgment. The main questions it aims to answer are: What is the incidence of vitamin C deficiency in hospitalized patients with hemorrhagic symptoms? Is a standardized screening protocol more effective than traditional clinical judgment in identifying vitamin C deficiency? Is vitamin C deficiency associated with anemia, other micronutrient deficiencies (folate, B12, albumin, iron), or infectious conditions? Does vitamin C deficiency impact hospital length of stay? Researchers will compare a systematic screening approach based on predefined hemorrhagic criteria (e.g., hematuria, ecchymosis, epistaxis, petechiae, gastrointestinal bleeding, or intracranial hemorrhage) to the traditional physician-judgment approach to determine its effectiveness in identifying vitamin C deficiency. Study Design Participants will: Be hospitalized adults (≥18 years old) presenting with documented micro- or macroscopic hemorrhagic signs. Undergo vitamin C level assessment either as part of the standardized screening protocol (prospective arm) or based on physician judgment (retrospective control group). Have additional clinical and laboratory data collected, including hemoglobin levels, platelet count, iron status, vitamin B9/B12 levels, and other relevant parameters. This non-interventional study will not modify the standard of care but will systematically assess the prevalence of vitamin C deficiency in at-risk patients and evaluate the utility of a structured screening protocol.
