Design outcomes

Primary

MeasureTime frame
Main Objective: Evaluate the effectiveness of orally administered vitamin B12 compared with intramuscular to reestablish the seric level of vitamin B12 at 8, 26 and 52 weeks in patients = 65 years with B12 deficiency, attended in the primary care centers in the Community of Madrid. ;Secondary Objective: 1.Evaluate the safety of both treatment groups. 2.Analyze the quality of life measured by Euroqol-5D. 3.Describe the satisfaction and preferences with specific questions designed for this project, in both treatment groups. 4.Analyze the degree of compliance measured by counting the unused vials in the oral treatment and the number of injections received in the intramuscular treatment. 5.Describe the sociodemographic profile, living habits and the clinical manifestations of patients with vitamin B12 deficiency ;Primary end point(s): Main outcome variable measured in both groups: Normalization of the levels of plasmatic vitamin B12 (B12>179pg/ml, at 8, 26, 52 weeks)=YES /NO ;Timepoint(s) of evaluation of this end point: At 8, 26, 52 study weeks

Secondary

MeasureTime frame
Secondary end point(s): Variables Secondary Result -Level of vitamin B12 (pg/ml) -Adverse events: description, onset and resolution, intensity (degree), evaluation of the relationship of causality with the medication and severity criteria mesured in all visits. -Compliance with treatment: measured by counting the unused vials in the oral treatment and the number of injections received in the intramuscular treatment. -Quality of life, measured by Euroqol-5D questionnaire. -Satisfaction and preferences of patients about form of administration: this will be evaluated at the end of the study with a specific question.;Timepoint(s) of evaluation of this end point: Throughout the study
