In a hospital setting, I have come across numerous patients who would refused to have their blood drawn due to different reasons. Some are scared of needles, some are trying to hide their drug dependency, being stubborn or non compliant, due to religious belief, being in denial, mental health status etc. Below are some of those consequences:

  1. Inability to properly diagnose a patient. Although there are other ways of diagnosing patients. Blood tests gives physicians clear picture of one’s health.

How To Encourage Patients For Blood Tests

  1. Prepare them by giving instructions ahead of time in a calm and mild manner.
  2. Set realistic expectations to build trust.
  3. Giving them proper nursing education about a certain test, helps as some of them has false beliefs or has no awareness of certain tests and how a certain test once obtained may help them in the end.
  4. Draw patients blood carefully and safely because some of them has experienced multiple sticks that makes them phobic of blood draw.
  5. Sometimes informing them of the consequences of not having their blood drawn gives them ideas of how important it is.

  9. At times, it is better for some patients to hear it from the doctors on why a certain blood draw is being ordered.
  10. Acknowledge their issues or concerns which are probably legitimate and may need some accommodations like some patients would request for a certain nurse to draw their blood or would rather have a Doppler guided blood draw done.

Nurses Roles And Responsibilities With Blood Tests

When I started with my nursing profession, blood draws were done by Medical Technologies or Phlebotomists. Although there are still hospitals or health care settings who has employed Phlebotomists to draw in-patient blood draw, it is now a common practice for nurses to draw blood. So it is very important to practice and be very skilled with this as blood tests are very important. Make sure to draw blood carefully and skillfully.

Our patients lives, health and well-being relies upon us. Patients becomes at ease and develops trusts when they know that we have the proper know how and ability to care for them. They entrust us with their health and their personal information that are related to their condition because they are comfortable and are aware that we are competent.

Drawing blood is not always easy as patients don’t always have good veins when they enter the hospitals. They sometimes come to the emergency department very sick, dehydrated, has severe blood loss or anatomically is not endowed with good noticeable vein. It becomes a challenge for nurses especially new graduates so it is very important to help them develop the skill in blood draw. It is important to properly mentor new students wherein they should be given enough time to practice and be knowledgeable of certain techniques especially with older populations of patients.

Making nurses more competent with blood draw eliminates a high percentage of patient refusing blood tests as it is one of the most reasons of refusal based on my experience. It is the lack of trust that the nurse will be able to get the stick once why patient dread blood draws. It is the notion that the nurse will be inflicting him/her pain through blood draw that they become so elusive with this test, which becomes difficult for doctors to properly diagnose a patient.

I hope I am able to clarify some misconceptions and was able to assist you in understanding more about blood tests.
