  • DOT is method devised to ensure TB patients are taking their medications as directed and that they essentially complete an adequate course of TB treatment with little to no interruptions
  • This method of medication administration is proven to be effective in treating TB patients and is associated with better treatment outcomes We can ensure patients are getting the recommended doses and can furthermore reduce the frequency of the development of drug resistance and treatment failure or relapse so this explains Why DOT is so important in the treatment of Tuberculosis
  • So when we are giving DOT there are a couple of very important things to remember DOT is not dropping medications off at the patient’s door-step Neither is it allowing patients to self administer medications And we should never entrust a patient’s family member to administer medications in lieu of the DOT worker
  • Again, this is a re-cap of the information presented on the previous slide, however; I would like to touch on the last bullet point Medical professionals should not be allowed to self administer TB medications. They are to patients and a DOT workers must go out and witness the ingestion of those medications
  • Now with DOT there are advantages and disadvantages as noted here Advantages are…..
  • Traditional example of disease treatment: treatment is offered, but it is up to the patient to take it. This is not the case with DOT The treatment of TB is different; responsibility for achieving a cure is placed upon the treating physician and the public health case management team. We are responsible for ensuring the patient is treated appropriately and taking medications as directed In essence, we “ meaning public health” must achieve the cure.

      • “… any public health program or private provider ( or both) undertaking to treat a patient with tuberculosis is assuming a public health function that includes not only prescribing an appropriate regimen but also ensuring adherence to the regimen until treatment is completed”
  • Social Barriers that Affect DOT Adherence
    • Drug Addictions
      • Competing priority of obtaining drugs vs. being available to receive DOT
    • Employment
      • Patient may work in another city and can’t make it to the clinic for DOT
    • Mental Illness
      • Patient can’t comprehend the disease and the need for medications
      • Denial
  • Knocking Down Social Barriers
    • Be Familiar with Alcohol and drug treatment Centers in your area
    • Call other HD to ask for assistance with DOT if your patient is in their area
    • Assess for mental health issues early and give appropriate referrals
  • Cultural Barriers that Affect DOT Adherence
    • Limited or No English
      • Trained interpreters should be available

      • Age
      • Sex
      • Race
      • Education
      • Occupation
      • Socioeconomic status
  • The Non-Adherent Patient
    • Non –Adherence can be caused by many reasons
    • A Patient that is Non-Adherent to DOT may be….
      • Sick for longer Period of Time
      • Spread the Disease to Others
      • Develop and spread drug-resistant TB
      • Die as the result of interrupted treatment
  • Common Causes For Non-Adherence
    • Social and Cultural Beliefs
    • Competing Priorities
      • Education
      • Employment
    • Patient No Longer Feels Sick
    • Mental Capacity
    • Lack of Motivation
    • Poor Relationships with Healthcare Workers
    • Control Issues
  • Tried Everything
    • Centers for Disease Control and Prevention
      • “ individuals have the right to ignore a doctor's advice or refuse
      • treatment if they wish. However, persons with infectious TB may
      • lose that right if health officials believe these persons risk infecting
      • others by not taking their prescribed medicine. Patients who are
      • unwilling or unable to adhere to treatment may be required to do
      • so by law or may be quarantined or isolated until noninfectious.”
    • Health care workers should
      • notify the appropriate supervisory clinical and management staff when patients are non-adherent
    • Determine why the patient is non-adherent and begin strategies that will help the patient finish treatment before legal measures are taken
  • Quarantine
    • When All Else Fails
      • TB control programs should not begin procedures for confining patients to a treatment facility until after the patient has shown that he or she is unable or unwilling to follow a treatment
    • Involuntary confinement or isolation for inpatient treatment should be viewed as the last resort.
    • Criteria for Determining the Need for Involuntary Confinement
      • Laboratory results (acid-fast bacilli smears and cultures)
      • Clinical signs and symptoms of infectious TB
      • An abnormal chest radiograph, especially if cavities are present
      • A history of non-adherence (not caused by factors outside patient's control)
      • The opportunity to infect others
  • Case Study 1
    • You are assigned to deliver DOT to Mrs. Wilson, a 76-year-old woman who lives alone in the house she and her husband bought many years ago. Mrs. Wilson was recently released from the hospital. Upon discharge from the hospital, she received education about TB and about the need to take medications until she completes treatment. She was told that she would be started on DOT and a health care worker would visit her at her home to help her take her medication. Mrs. Wilson is elated to have some company. She happily offers you cookies and wants to "talk awhile" before she takes her medication.
    • What are the tasks you complete when you deliver DOT to Mrs. Wilson?

  • Case Study 2
    • Nick is a 27-year-old single unemployed male. He has been in and out of rehabilitation clinics for crack use. He picks up odd jobs in the warehouses and diners on the waterfront. He lives in a single room occupancy hotel. Four weeks ago he was brought by the police to the emergency room of General Hospital for treatment of stab wounds to the right arm resulting from a drug deal gone bad.
  • Continued….
    • Upon admission he was intoxicated, appeared poorly nourished and underweight, and had a productive cough.
    • His smears were positive for AFB and he was started on appropriate therapy. He remained in the hospital for 5 days.
    • Against medical advice, Nick then insisted on leaving the hospital. On the day of discharge, the infection control nurse telephoned a report to the health department, and instructed Nick to go to the health department the next morning for evaluation and a supply of medicine .
  • Non-Adherent Nick
    • He failed to keep his appointment. The next week a health care worker was assigned to locate Nick and persuade him to come to the clinic. The health care worker found him lying on a park bench near the hotel where he lives. The health care worker convinced Nick to go to the clinic for follow-up tests. At the clinic, Nick reluctantly agrees to take his medication, although he does not want DOT. He says he is not a "baby" and can take the medication on his own.

      • Nick doesn't seem to understand the importance of finishing treatment. Therefore, adherence may be very difficult.
    • Educate Nick about TB and its treatment
      • As part of patient education, Nick should be told that some people have trouble staying on the medication schedule
      • Help Nick find ways to identify and deal with potential adherence problems .
    • Nick is more likely to be adherent if he helps make the decisions and chooses the solutions
    • Nick may be more likely to follow the treatment plan if he understands his illness and the benefits of treatment.
    • Offer Incentives and/or Enablers to help Nick Adhere to Treatment.
  • Patient Education and Rapport Building
    • Explain the benefits of DOT to Nick and to stress the fact that DOT is not punitive.
    • Explain that DOT is more than watching Nick swallow each pill.
