Study Design Characteristics:
- Allocation: NON_RANDOMIZED
- Intervention Model: FACTORIAL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* In both phases, all children and adolescents (aged \<18 years) starting anti-TB treatment due to close contact with a TB patient (primary chemoprophylaxis), Latent Tuberculosis Infectious (LTBI) or Tuberculosis (TB) disease were eligible to participate in the study.~Exclusion Criteria:~* Referral from another center after anti-TB treatment had already begun~* Patients with other chronic diseases requiring hospital follow-up and/or other chronic therapies~* Known poor previous adherence to anti-TB treatment (if treatment was repeated or restarted)~* A significant language barrier that prevented the child or his/her relatives from properly understanding the nature of the study.

- Gender: ALL
- Minimum Age: None
- Maximum Age: 18 Years
- Healthy Volunteers: f

Study Arms:
- Phase 1, Retrospective (Type: NO_INTERVENTION): Routine outpatient follow-up visits were scheduled as follows: (a) in patients receiving primary chemoprophylaxis or Latent Tuberculosis Infection (LTBI) treatment: baseline visit, and 2 weeks and 3 months later (end of treatment in most cases); (b) in patients treated for Tuberculosis disease: baseline visit, 2 weeks later and on a monthly basis thereafter.
- Phase 2, Prospective (Type: EXPERIMENTAL): Four nurse-led interventions were implemented after Phase 1:~* Intervention 1: at baseline visit, the parents or carers of the children, were given a leaflet in the mother tongue. This leaflet was available in 10 different languages: Spanish and Catalan (the two official languages of the country), English, French, German, Russian, Romanian, Chinese, Urdu and Arabic.~* Intervention 2: a follow-up open telephone call was made 7-10 days after the baseline visit and whenever the patient failed to attend the scheduled visits.~* Intervention 3: the Eidus-Hamilton test was performed twice, 2 weeks after the baseline visit and at the end of treatment. To prevent patients from only taking their medication occasionally, directly before their visits, they were not informed of the purpose of the urine test.~* Intervention 4: a written questionnaire about adherence to anti-TB treatment on all the follow-up visits.

Based on this trial design, predict the completion outcome and termination type (if applicable).
