Deshabituación tabáquica a largo plazo. Estudio de 1.639 pacientes incluidos en programa de intervención psicofarmacológico tras 12 años de seguimiento / Long-term tobacco cessation. A study of 1639 patients included in a sychopharmacological intervention program after 12 years of follow-up

RESUMEN

Objetivos: evaluar la situación de abstinencia tras una media de 12 años en pacientes que realizaron un programa de intervención psicofarmacológica. Metodología: se incluyeron pacientes tratados en una Unidad Especializada de Tratamiento del Tabaquismo con terapia psicológica asociada, o no, a tratamiento farmacológico. El seguimiento inicial fue de 1 año. Se dividió en dos grupos aquéllos pacientes en los que se objetivó abstinencia (cooximetría (CO) <5 ppm) tras el año de seguimiento (grupo A) y aquéllos pacientes no abstinentes (grupo B). Los pacientes fueron llamados por teléfono tras un periodo de 12 años de media y se comprobó la abstinencia. En caso de indicar que no fumaban, se invitó a que acudieran a nuestras consultas para confirmarlo con CO. Se consideró abstinencia confirmada (AC) si presentaban CO <5 ppm. En caso de no acudir, se indicó situación de abstinencia no confirmada (ANC). Se consideró fracaso (F) si el paciente indicaba que fumaba. Resultados: se estudiaron 1.639 pacientes (366 del grupo A y 1.273 del grupo B). A largo plazo, en el grupo A presentaron AC el 50,5% de los pacientes, ANC 11,7%, F el 20,8%, no fueron localizados el 13,9% y fallecieron el 3,6%. En el grupo B presentaron AC 5,8%, ANC 12,6%, F 45%, no localizados 29,7%, fallecidos 6,7% (p <0,01 entre ambos grupos, excepto ANC). Conclusiones: los pacientes que dejan el tabaco tras un año de seguimiento mantienen la abstinencia a largo plazo en más de la mitad de los casos

ABSTRACT

Objectives: to evaluate abstinence status after an average of 12 years in patients who underwent a psychopharmacological intervention program. Methods: the study included patients treated at a specialized tobacco cessation unit who received pharmacological treatment with or without associated psychological therapy. The initial follow-up lasted 1 year. Patients were divided into two groups those who showed abstinence (CO-oximetry <5 ppm) after a year of followup (group A) and non-abstinent patients (group B). Patients were contacted by phone after an average of 12 years to confirm abstinence. If they indicated they did not smoke, they were invited to our clinics to confirm this with COoximetry. A CO-oximetry result of <5 ppm was considered confirmed abstinence. If patients did not visit the clinic, their status was recorded as unconfirmed abstinence. Status was considered failure if the patient indicated they smoked. Results: 1639 patients were studied (366 in group A and 1273 in group B). In the long run, abstinence was confirmed in 50.5% of patients, unconfirmed in 11.7%, 20.8% were recorded as failure, 13.9% could not be contacted and 3.6% had died in group A. In group B, 5.8% were recorded as confirmed abstinence, 12.6% as unconfirmed abstinence, 45% as failure, 29.7% could not be contacted and 6.7% had died (p <0.01 between both groups, except unconfirmed abstinence). Conclusions: patients who cease tobacco use after a year of follow-up maintain long-term abstinence in more than half of cases
