Social support from nurses and non-adherence with directly observed therapy (DOTS) maintenance phase among patients with tuberculosis in Metro Manila, Philippines

Objective To determine the influence of community health nurses' social support on non-adherence with the maintenance phase of directly observed therapy (DOTS) among patients with tuberculosis (TB). Design Prospective-cohort. Sample One hundred purposively selected patients with TB starting with DOTS maintenance phase. Measurements Participants answered the robotfoto and Berlin Social Support Scale (BSSS) to assess demographics and social support provided by nurses. Non-adherence was measured using the attendance record and documented in an abstraction form. Cox proportion-hazards regression determined the influence of social support provided by nurses to non-adherence. Results With a median adherence of 3 weeks, 15% of the sample was non-adherent. The hazard of non-adherence was lower with high perceived emotional support (HR = 0.25, p = .046), perceived instrumental support (HR = 0.20, p = .044), perceived support seeking (HR = 0.27, p = .045), and received emotional support (HR = 0.45, p = .045). High received emotional support increased non-adherence (HR = 2.65, p = .039). Conclusion Social support from nurses influenced DOTS non-adherence among patients with TB, a critical issue in the development of drug-resistance. Perceived emotional, instrumental, support seeking and received emotional support decreased the hazard of non-adherence, while received emotional support increased non-adherence. This study highlights the need to promote positive perception of instrumental support needs. Appropriate interventions should be provided to promote support-seeking skills.
