Effectiveness of regular reporting of spirometric results combined with a smoking cessation advice by a primary care physician on smoking quit rate in adult smokers: a randomized controlled trial. ESPIROTAB study.

BACKGROUND: Undiagnosed airflow limitation is common in the general population and is associated with impaired health and functional status. Smoking is the most important risk factor for this condition. Although primary care practitioners see most adult smokers, few currently have spirometers or regularly order spirometry tests in these patients. Brief medical advice has shown to be effective in modifying smoking habits in a large number of smokers but only a small proportion remain abstinent after one year. The aim of this study is to evaluate the effectiveness of regular reporting of spirometric results combined with a smoking cessation advice by a primary care physician on smoking quit rate in adult smokers. METHODS/DESIGN: Intervention study with a randomized two arms in 5 primary care centres. A total of 485 smokers over the age of 18 years consulting their primary care physician will be recruited.On the selection visit all participants will undergo a spirometry, peak expiratory flow rate, test of smoking dependence, test of motivation for giving up smoking and a questionnaire on socio-demographic data. Thereafter an appointment will be made to give the participants brief structured advice to give up smoking combined with a detailed discussion on the results of the spirometry. After this, the patients will be randomised and given appointment for follow up visits at 3, 6, 12 and 24 months. Both arms will receive brief structured advice and a detailed discussion of the spirometry results at visit 0. The control group will only be given brief structured advice about giving up smoking on the follow up. Cessation of smoking will be tested with the carbon monoxide test. DISCUSSION: Early identification of functional pulmonary abnormalities in asymptomatic patients or in those with little respiratory symptomatology may provide "ideal educational opportunities". These opportunities may increase the success of efforts to give up smoking and may improve the opportunities of other preventive actions to minimise patient risk. Comparing adult smokers in the intervention group with those in the control group, a minimum improvement expected with respect to the rates of smoking cessation would represent a large number of avoided morbimortality.

[Interactions between herbals medicines and drugs in chronic patients with complexity in primary care.] / Interacciones entre plantas medicinales y medicamentos en pacientes crónicos complejos en atención primaria.

OBJECTIVE: Taking medicinal herbs (MH) is frequent in patients and can cause interactions with others medications. Consumption of MH could be high in chronic patients with complexity (CPC) and produce interactions with drugs and knowledge about these drugs in primary health care (PC) professionals about these interactions is low. The aim was to measure the prevalence of potencial interactions between HM and drugs in CPC and evaluate the degree of knowledge of PC professionals. METHODS: Descriptive observational study in a population of CPC assigned to two PC teams. We investigated MH consumption through interviews and review potential drug interactions. We evaluated the degree of professionals knowledge through a survey designed for the study. A descriptive analysis was carried out. The Student-t test for paired data was used to compare the means.The statistical significance was established at p<0.05. RESULTS: The survey was distributed among 179 patients, mean age 76.9 years old (DE 9.7), 54.6% women. 62.57% (112) take MH. We detected 88 potentially relevant interactions in 51 patients (45.54%). Of the 219 professionals interviewed 51.1% consider that their knowledge about MH were low and 64,4% thought that was important to know the mH consumption of their patients. CONCLUSIONS: We detected a high prevalence of MH consumption in CPC and interactions between herbs medicinal and drugs. Lack of knowledge of PC health professionals is important. It's necessary to record this consumption in the medical history and improve the knowledge of professionals about MH to detect possible interactions, reduce the associated risk and improve the quality of care.

OBJETIVO: El consumo de plantas medicinales (PM) es frecuente en pacientes y puede causar interacciones con otros medicamentos. El consumo de PM puede ser alto en pacientes crónicos complejos (PCC) y producir interacciones con su medicación y el conocimiento sobre estos fármacos en profesionales sanitarios de Atención Primaria (AP) es bajo. El objetivo del estudio fue medir prevalencia de interacciones potenciales entre PM y medicamentos en PCC y evaluar grado de conocimiento de los profesionales de AP. METODOS: Estudio observacional descriptivo en una población de PCC asignados a dos equipos de AP. Se evaluaron el consumo de PM mediante entrevistas y se revisaron las interacciones potenciales con su medicación. Se evaluó el grado de conocimiento de los profesionales mediante una encuesta diseñada para el estudio. Se realizó un análisis descriptivo, La comparación de medias se realizó con la prueba t de Student. La significación estadística se estableció en p<0,05. RESULTADOS: La encuesta se distribuyó entre 179 pacientes, con una edad media de 76,9 años (DE 9,7), 54,6% mujeres. El 62,57% (112) consumieron PM. Detectamos 88 interacciones potencialmente relevantes en 51 pacientes (45,54%). De los 219 profesionales entrevistados el 51,1% consideraron que sus conocimientos sobre PM eran bajos y 64,4% pensaron que era importante conocer el consumo de PM de sus pacientes. CONCLUSIONES: Detectamos una alta prevalencia del consumo de PM en PCC y de interacciones entre PM y medicamentos. La falta de conocimientos de los profesionales sanitarios es importante. Es necesario registrar en la historia clínica este consumo y mejorar el conocimiento de los profesionales de AP sobre PM para detectar posibles interacciones, disminuir el riesgo asociado y mejorar la calidad asistencial.
