Nurses handling the Tuberculosis Directly Observed Treatment Short Course (TB-DOTS) are crucial in implementing the National Tuberculosis Program (NTP), which faced challenges during COVID-19. Hence, this study aimed to explore and to understand the TB DOTS Nurses' lived experiences on implementing NTP amidst the COVID-19 pandemic.

A descriptive phenomenology research design was used in this study among purposively selected 15 TB DOTS nurses during the pandemic, using in-depth interviews. Descriptive phenomenology was chosen to focus on capturing and describing the nurses' direct experiences. Data were manually transcribed into EXCEL software, coded, clustered, and thematized. Data were also collected from January to April 2023, following IATF Guidelines. Colaizzi's descriptive phenomenology method was employed for analysis, allowing the study to remain true to the participants' own words and perspectives.

This study revealed three major themes with associated subthemes anchored from the significant statements extracted from the participants' verbatims. The first theme, “Menace of Uncertainties,” echoed nurses’ fears of contracting the disease, struggles with implementing the NTP, and balancing patient care with personal well-being. Despite obstacles, nurses formed support systems and remained determined, leading to the emergence of the second theme, "Seeing Light in the Darkness." The third theme, "Establishing a Strong Foundation," outlined nurses' ideas for managing the NTP during a pandemic.

The study underscored the significant challenges TB DOTS nurses faced during the pandemic, including fear, uncertainty, and difficulty balancing personal well-being with patient care. Despite these obstacles, nurses demonstrated resilience, adaptability, and a commitment to their work. The findings underscored the importance of support systems, flexibility, and enhanced resources in managing TB cases during crises. These insights had direct implications for nursing practice, education, and research, while having emphasized the need for improved facilities, support mechanisms, and training to better equip nurses for future health emergencies.
