[Cost-effectiveness of an alternative tuberculosis treatment: home-based guardian monitoring of patients]. / Costo-efectividad de un tratamiento antituberculoso alternativo: seguimiento a convivientes residenciales de los pacientes.

OBJECTIVE: Estimate the cost-effectiveness ratio of the directly observed treatment short course (DOTS) for treatment of tuberculosis (TB), comparing it to a variation of this treatment that includes increased home-based guardian monitoring of patients (DOTS-R). METHODS: Taking a social perspective that includes the costs for the health institutions, the patients, and their family members, and for other entities that contribute to making operation of the program effective, the costs incurred with each of the two strategies were evaluated and the cost-effectiveness ratios were estimated adopting the measures of effect used by the control programs. The estimate of the cost of each of the two strategies includes the cost to the health institutions that administer treatment, the patients and their family members, and the cost to the Ministry of Health that manages public health programs on the municipal level. Based on these costs and the number of cases cured and treatments completed as outcome measures of each of the strategies evaluated, the cost-effectiveness ratio and incremental cost were calculated. RESULTS: The DOTS-R was found to be more cost-effective for achievement of successful treatments than the DOTS. The DOTS-R recorded costs of US$ 1 122.40 to US$ 1 152.70 for each case cured compared to values of US$ 1 137.00 to US$ 1 494.30 for the DOTS. The percentage of cases treated successfully was higher with DOTS-R than with DOTS. CONCLUSIONS: The DOTS-R is a promising cost-effective alternative for improved control of TB in endemic areas. It is recommended that the health authorities include home-based guardian monitoring of patients in their institutional management of the TB program, with the participation of health workers and the physical and financial resources that currently support this program.

Costo-efectividad de un tratamiento antituberculoso alternativo: seguimiento a convivientes residenciales de los pacientes / Cost-effectiveness of an alternative tuberculosis treatment: home-based guardian monitoring of patients

Objetivo. Estimar la relación de costo-efectividad del tratamiento de corta duración bajoobservación directa (DOTS), comparándolo con una variación de dicho tratamiento, que incluyeun mayor seguimiento a los convivientes residenciales de los pacientes (DOTS-R) parael tratamiento de tuberculosis (TB).Métodos. Tomando una perspectiva social que incluye los costos para las institucionesde salud, para los pacientes y sus familiares, y para otras entidades que contribuyen a hacerefectiva la operación del programa, se evaluaron los costos incurridos con cada una de las dosestrategias y se estimaron razones costo-efectividad adoptando las medidas de efecto usadas porlos programas de control. La estimación de los costos de cada una de las dos estrategias incluyelos correspondientes a las instituciones de salud que administran el tratamiento, los pacientesy sus familiares, y los de la secretaría de salud que gestiona los programas de salud pública anivel municipal. Con base en estos costos y el número de casos curados y tratamientos terminadoscomo medidas de resultado de cada una de las estrategias evaluadas, se calcularon lasrazones costo-efectividad y costo incremental.Resultados. El DOTS-R se halló más costo-efectivo para lograr tratamientos exitosos queel DOTS. El DOTS-R registró costos de entre US$ 1 122,4 y US$ 1 152,7 por caso curado,comparados con valores de entre US$ 1 137,0 y US$ 1 494,3 correspondientes al DOTS. Laproporción de casos tratados con éxito fue mayor con DOTS-R que con DOTS.Conclusiones. El DOTS-R es una alternativa costo-efectiva promisoria para mejorar elcontrol de la TB en sitios endémicos. Se recomienda a las autoridades del sector salud incorporaren su gestión institucional del programa contra la TB, acciones de seguimiento de losconvivientes de pacientes, con la participación del personal de salud y los recursos físicos yfinancieros que apoyan actualmente dicho programa.
