Clinical Trial Summary
Tuberculosis (TB) is a preventable and curable disease mostly affecting lungs and caused by
the bacteria called as Mycobacterium Tuberculosis (MTB). It is estimated that approximately
10 million people are diagnosed with TB every year in the world and 1.7 billion people are
infected by MTB and at risk in terms of the development of the disease. Contacted person is
the one who shares the same environment with the patient suffering from contagious TB and is
exposed to MTB bacilli.
Today, the aim of the TB control and prevention programs is to determine the active TB
patients and provide cure by healing and also to screen those contacted with the TB patients
and determine whether or not they have latent TB infection and treat them and to detect the
active cases among the contacts. In the current guidelines, the importance of screening all
the contacts of the patients with pulmonary TB and applying a protective treatment for the
household in terms of community health care is emphasised. For this reason, it is of prime
importance to perform contact screening of the relatives of the TB patients and apply
protective treatment. The patients receiving TB and TB protection treatment need to use
medicine regularly for at least six months. It is highly important to adherence this period
for the success of the treatment. However, it has been reported in the literature that the
rate of nonadherence to the TB treatment varies between 20-80% and the nonadherence to the TB
treatment is the most serious barrier in the control of the disease. İncomplete treatment may
result in long-lasting infection, drug resistance, relapse, and death.
In the litareture, it has been stated in the study conducted with the individuals with some
chronic diseases that tele-follow-up is effective in providing the self-care agency of
patients and the cognitive-social adaptation. It has been reported that some problems emerge
especially in the TB patients such as the interruption of treatment, forgetting medication
(24.5%), side-effects of drugs, (23.3%), symptomatic recovery (19.5%), failure to know the
necessity of completing the life cycle of drugs by most of patients and not receiving
adequate training and these problems may be managed more effectively by tele-follow-up.
As is known, nurses are involved in all the processes of protecting-promoting the health of
the individuals, families and society and their recovery in case of disease. Moreover,
providing the protective treatment by performing the required screening for treating TB
patients, their follow-up and preventing the development of disease in contacted ones has a
vital importance in preventing the spread of TB in the society. Nurses may follow the
findings of patients, obtain information about the process, produce information and transmit
information with this system (reporting drug changes, performing training follow-up of
patients etc.). In the literature, it has been emphasised that tele-mobile nursing services
is a cost-effective method since it decreases the hospitalisation rate and period of the TB
patients. Accordingly, the main aim of this study is to assess the effect of the training and
the telephone follow-up provided by the nurse for the TB patients and contacts on the
medication adherence.
This research was conducted as a randomised, controlled and quasi-experimental study to
determine the effect of the training and telephone follow-up provided to the TB patients and
contacts on the treatment adherence. The population of the study was composed of the patients
receiving treatment in a tuberculosis control dispensary between July 2018-July 2019. The
sample size was calculated to be 28 in each group through power analysis. Eighty-one TB
patients and 90 TB contacts were included in the study. However, 15 TB patients and 3
contacts were excluded since they were transferred to another dispensary and they died. The
study was completed with 66 TB patients in the intervention (n= 32) and control groups (n=34)
and 87 contacts in the intervention (n= 41) and control groups (n = 46) The TB patients who
applied to the dispensary and their contacts were informed about the aim and scope of the
study. Then, four groups were formed by using the randomisation menu of the computer program:
the intervention and control groups for the TB patients and the intervention and control
groups for the contacts. The randomisation was conducted by a statistics specialist who had
no contact with the participants. All participants were blinded to the randomisation
procedure. However, the researchers were not blinded to the patient groups, due to the nature
of the intervention.
The interviews were performed by using the face-to-face interview technique in the outpatient
clinic. In the first interview, the questionnaire was applied to four groups; TB intervention
and TB control group, Contact intervention and Contact control group.
