Effect of a Web Page Based on a Motivational Video for Voluntary Blood Donation
Condition: Blood Donors
Study type: Interventional

Summary: 
      Voluntary blood donation is currently a key issue in many countries, as the shortage of
      voluntary donors results in a deficit in the supplies of the Blood Banks of the hospitals.
      One factor for which there is a low number of voluntary donors is the limited dissemination
      of information that is given to the population regarding the facilities and benefits of blood
      donation.

      Objective: To evaluate the effect of a web page containing a motivational video and an
      informative text to promote the voluntary donation of blood disseminated through the use of
      social networks such as Facebook and WhatsApp.

      Design and Participants: Online randomized controlled trial for a group of 102 university
      students.

      Intervention: One group exposed to the intervention with video and the other control group
      exposed to informative text.
    

Detailed description: 
      PROBLEM STATEMENT The shortage of voluntary blood donors is a constant worldwide problem,
      since many lives depend on a transfusion every day to carry out medical or surgical
      treatment, however, the demand is so high that it exceeds the available number of units of
      blood. That is why the WHO recommends that at least 2% of the total population donate blood
      to supply the national demand for blood units. It is known that Peru needs around 520,000
      units of blood per year to be able to supply the national demand of blood banks (19). In
      2017, only 1.08% of the Peruvian population donated blood.

      The shortage of blood supply in the blood banks of hospitals is a problem worldwide. The
      demand for blood has increased in recent decades. This is because blood and its derivatives
      are used to attend to procedures that support the patient's well-being. It is due to this
      high demand that all the countries of the world have found themselves in need of generating
      national laws and systems that help to boost research and voluntary blood donation.

      When developing strategies for the promotion of the voluntrary blood donation, it is
      necessary to know the perceptions that donors have regarding the donation. A study conducted
      in a hospital in Lima showed the positive and negative aspects regarding blood donation,
      which resulted in one of the negative aspects is the limited publicity that is given
      regarding the blood donation. The donors interviewed suggested that advertising could be done
      through the internet, spreading the information through emails or through the use of
      Facebook.

      HYPOTHESIS It is proposed that there is a significant difference in the increase in the
      intention to donate blood voluntarily after exposing the participants to a motivational video
      about blood donation compared to participants exposed to an informative text about blood
      donation. Both groups will receive the information (video or text) through a web page.
    

Intervention name(s): Video through a web page; Informative text
Intervention type(s): Other; Other
Intervention description(s): Participants will see a video about blood donation.; Participants will see a brief text about blood donation.
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: Randomized controlled trial conducted online to compare the effect of a web intervention which will be developed through a web page containing a motivational video and an informative text for potential voluntary blood donors. The motivational video or the informative text will be offered randomly to each participant to evaluate the effect of each of them. The website will be offered through social networks Facebook and WhatsApp.
