Objective: A resolution passed by the government of the Brazilian state of São Paulo established a protocol for requesting free COPD medications, including tiotropium bromide, creating regional authorization centers to evaluate and approve such requests, given the high cost of those medications. Our objective was to analyze the requests received by an authorization center that serves cities in the greater metropolitan area of (the city of) São Paulo between 2011 and 2016. Methods: Data regarding the authorization, return, or rejection of the requests were compiled and analyzed in order to explain those outcomes. Subsequently, the clinical and functional data related to the patients were evaluated. Results: A total of 7,762 requests for dispensing COPD medication were analyzed. Requests related to male patients predominated. Among the corresponding patients, the mean age was 66 years, 12% were smokers, 88% had frequent exacerbations, and 84% had severe/very severe dyspnea. The mean FEV1 was 37.2% of the predicted value. The total number of requests decreased by 24.5% from 2012 to 2013 and was lowest in 2015. Most (65%) of the requests were accepted. The main reasons for the rejection/return of a request were a post-bronchodilator FEV1/FVC ratio > 0.7, a post-bronchodilator FEV1 > 50% of the predicted value, and failure to provide information regarding previous use of a long-acting β2 agonist. During the study period, the total number of requests returned/rejected decreased slightly, and there was improvement in the quality of the data included on the forms. Conclusions: Here, we have identified the characteristics of the requests for COPD medications and of the corresponding patients per region served by the authorization center analyzed, thus contributing to the improvement of local public health care measures.

Background: Tuberculosis cure is dependent upon treatment adherence. Objective: To analyze the results of tuberculosis treatment in public health clinics in the city of Campinas, in the state of São Paulo, Brazil, during 2002. Method: From a cohort of 484 patients diagnosed with tuberculosis, we evaluated 436. Treatment outcomes were described for all patients, whether new patients or patients in retreatment, including those presenting the pulmonary form, with or without acquired immunodeficiency syndrome (AIDS) comorbidity. Results: The success rate was 68.6% (72.3% among non-AIDS patients and 57.6% among AIDS patients). Among new cases, the non-AIDS group presented a 2.2-times greater chance of presenting favorable results. In the AIDS group, no differences were observed between new patients and those in retreatment. Among the unfavorable outcomes, only lethality presented a difference (18.9% among AIDS patients and 8.0% among non-AIDS patients). In patients presenting the pulmonary form, the success rate was similar between those who were initially acid-fast bacilli positive and those who were not. Conclusion: The tuberculosis control program in Campinas presented low effectiveness. In comparison to the 2001 national cohort, success rates were higher for non-AIDS patients but lower for AIDS patients. The higher success rate among cases of tuberculosis without AIDS was primarily derived from the treatment of new cases. The unfavorable profile of tuberculosis patients co-infected with AIDS, characterized by the (18.9%) lethality and the (15.3%) noncompliance, were partially responsible for the lower success rate seen among such patients. It is notable that such high proportions of noncompliant patients were seen in a city providing easy access to treatment. In order to improve the program, medical teams should receive further training in supervised treatment, health education and techniques for interacting with patients, all of which will require considerable investment.

Objective: To describe COPD pharmacological treatment patterns in the state of Bahia, Brazil, and to evaluate the extent to which these patterns conform to clinical guidelines for the management of COPD. Methods: This was a cross-sectional study of 441 patients referred from the Public Health Care Network of the state of Bahia to a public referral outpatient clinic of a COPD management program of the Brazilian Unified Health Care System. Individuals with a spirometry-confirmed diagnosis of moderate to very severe COPD were included in the study. Patients were evaluated as to whether they had used any COPD medications in the last seven days. The appropriateness or inappropriateness (undertreatment or overtreatment) of the patient's pharmacological treatment was evaluated by comparing the patient's current treatment with that recommended by national and international guidelines. Results: A total of 383 individuals were included in the analysis. Approximately half of the patients (49.1%) used long-acting bronchodilators. These patients were older and had had the disease longer. Of the sample as a whole, 63.7% and 83.0% did not receive pharmacological treatment in accordance with international and national recommendations, respectively. Inappropriateness due to undertreatment was indentified in more than half of the patients. Conclusions: Long-acting bronchodilators are frequently underused in individuals with moderate to very severe COPD within the Brazilian Unified Health Care System in the state of Bahia. Most patients in our sample were treated inappropriately, and undertreatment predominated. Strategies to improve access to long-acting bronchodilators and the quality of COPD pharmacological management are required.

Objective: Duchenne muscular dystrophy (DMD) is the most common form of muscular dystrophy in children, and children with DMD die prematurely because of respiratory failure. We sought to determine the efficacy and safety of yoga breathing exercises, as well as the effects of those exercises on respiratory function, in such children. Methods: This was a prospective open-label study of patients with a confirmed diagnosis of DMD, recruited from among those followed at the neurology outpatient clinic of a university hospital in the city of São Paulo, Brazil. Participants were taught how to perform hatha yoga breathing exercises and were instructed to perform the exercises three times a day for 10 months. Results: Of the 76 patients who entered the study, 35 dropped out and 15 were unable to perform the breathing exercises, 26 having therefore completed the study (mean age, 9.5  2.3 years; body mass index, 18.2  3.8 kg/m2). The yoga breathing exercises resulted in a significant increase in FVC (% of predicted: 82.3  18.6% at baseline vs. 90.3  22.5% at 10 months later; p = 0.02) and FEV1 (% of predicted: 83.8  16.6% at baseline vs. 90.1  17.4% at 10 months later; p = 0.04). Conclusions: Yoga breathing exercises can improve pulmonary function in patients with DMD.

Objective: To assess ICU patients with COPD, in terms of in-hospital characteristics, two-year mortality and two-year functional status of survivors. Methods: A prospective cohort study involving patients with acute exacerbation of COPD admitted to the ICUs of two hospitals in the city of Porto Alegre, Brazil, between July of 2005 and July of 2006. At two years after discharge, survivors were interviewed by telephone in order to determine Karnofsky scores and scores on a scale regarding activities of daily living (ADL). Results: The sample comprised 231 patients. In-hospital mortality was 37.7%, and two-year post-discharge mortality was 30.3%. Of the 74 survivors, 66 were interviewed (89%). The mean age at ICU admission was 74 ± 10 years, and the mean Acute Physiology and Chronic Health Evaluation II score was 18 ± 7. Two or more comorbidities were present in 87.8% of the patients. Of the 66 interviewees, 57 (86.3%) lived at home, 58 (87.8%) were self-sufficient, 12 (18.1%) required oxygen therapy, and 4 (6.1%) still required ventilatory support. There was a significant reduction in the quality of life and autonomy of the survivors, as evidenced by the Karnofsky scores (85 ± 9 vs. 79 ± 11, p = 0.03) and ADL scale scores (29 ± 5 vs. 25 ± 7; p = 0.01), respectively. Conclusions: In this patient sample, two-year mortality was quite high. Although there was a noticeable reduction in the functional status of the survivors, they remained self-sufficient.

Objective: To evaluate the responsiveness of the six-minute step test (6MST) to an aerobic physical training program (PTP) and to determine the efficacy of the PTP regarding spirometric variables during the 6MST, as well as physical performance, sensation of dyspnea, and SpO2 during the 6MST and the six-minute walk test (6MWT), in patients with COPD. Methods: This was a controlled, prospective randomized study involving patients clinically diagnosed with COPD, with an FEV1/FVC ratio < 70%, and having been clinically stable in the last two months. The patients were randomized to undergo a PTP on a treadmill, three times a week, for six weeks (PTP group) or not (control group). Histories were taken from all of the patients, who received regular respiratory therapy during the study period, undergoing physical examination and spirometry before and after bronchodilator use; incremental symptom-limited cardiopulmonary exercise testing; the 6MST; and the 6MWT. Results: Of the 36 patients that completed the study, 21 and 15 were in the PTP and control groups, respectively. In the PTP group, there was a significant increase in the number of steps climbed during the 6MST and in the six-minute walk distance (in m and % of predicted), as well as a significant decrease in the sensation of dyspnea during the 6MWT. Conclusions: The 6MST showed responsiveness to the PTP. However, the 6MWT appears to be more responsive to the PTP proposed.

Objective: To evaluate the anthropometric data obtained for residents of the city of São Paulo, Brazil, in a study of Latin America conducted in two phases (baseline, in 2003, and follow-up, in 2012). Methods: This was an analysis of data obtained for São Paulo residents in a two-phase population-based study evaluating the prevalence of COPD and its relationship with certain risk factors among individuals ≥ 40 years of age. The anthropometric data included values for weight, height, body mass index (BMI), and waist circumference. In the follow-up phase of that study, the same variables were evaluated in the same population sample as that of the baseline phase. Results: Of the 1,000 São Paulo residents enrolled in the baseline phase of that study, 587 participated in the follow-up phase, and 80 (13.6%) of those 587 subjects had COPD. Comparing the baseline and follow-up phases, we found increases in all anthropometric measures in both groups (COPD and non-COPD), although the differences were significant only in the non-COPD group. The subjects with mild COPD showed increases in weight and BMI (Δweight = 1.6 ± 5.7 and ΔBMI = 0.7 ± 2.2), whereas those with moderate or severe COPD showed reductions (Δweight = −1.7 ± 8.1 and ΔBMI = −0.4 ± 3.0), as did those with severe or very severe COPD (Δweight = −0.5 ± 5.4 and ΔBMI = −0.8 ± 3.3). Conclusions: Between the two phases of the study, the subjects with mild COPD showed increases in weight and BMI, whereas those with a more severe form of the disease showed reductions.

Objective: To report data regarding COPD patients admitted to the ICU of a referral hospital for respiratory diseases, including outcomes and treatment evaluation. Methods: Study of a series of patients with respiratory failure and COPD admitted to the ICU of Nereu Ramos Hospital, located in the city of Florianópolis, Brazil, between October of 2006 and October of 2007. Data related to demographics, causes of hospitalization, pharmacological treatment, ventilatory support, length of hospital stay, in-hospital complications, ICU mortality, and 28-day mortality were obtained from the medical charts of the patients. Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were calculated. Mortality at 18 months was assessed by subsequent telephone calls. Results: During the study period, 192 patients were admitted to the ICU, 24 (12.5%) of whom were diagnosed with respiratory failure and COPD. The mean length of ICU stay was 12.0 ± 11.1 days. Noninvasive ventilation was used in 10 of the 24 patients (41.66%) and failed in 5 of those 10. Invasive mechanical ventilation (IMV) was used in a total of 15 patients (62.5%). Overall ICU mortality and 28-day mortality were 20.83% and 33.33%, respectively. However, 18-month mortality was 62.5%. Conclusions: Respiratory failure associated with COPD was responsible for 12.5% of the ICU admissions. Orotracheal intubation and IMV were necessary in 62.5% of the cases. The ICU mortality rate was in accordance with that predicted by the APACHE II scores. However, late mortality was high.

Objective: Early tuberculosis diagnosis and treatment are determinants of better outcomes and effective disease control. Although tuberculosis should ideally be managed in a primary care setting, a proportion of patients are diagnosed in emergency facilities (EFs). We sought to describe patient characteristics by place of tuberculosis diagnosis and determine whether the place of diagnosis is associated with treatment outcomes. A secondary objective was to determine whether municipal indicators are associated with the probability of tuberculosis diagnosis in EFs. Methods: We analyzed data from the São Paulo State Tuberculosis Control Program database for the period between January of 2010 and December of 2013. Newly diagnosed patients over 15 years of age with pulmonary, extrapulmonary, or disseminated tuberculosis were included in the study. Multiple logistic regression models adjusted for potential confounders were used in order to evaluate the association between place of diagnosis and treatment outcomes. Results: Of a total of 50,295 patients, 12,696 (25%) were found to have been diagnosed in EFs. In comparison with the patients who had been diagnosed in an outpatient setting, those who had been diagnosed in EFs were younger and more socially vulnerable. Patients diagnosed in EFs were more likely to have unsuccessful treatment outcomes (adjusted OR: 1.54; 95% CI: 1.42-1.66), including loss to follow-up and death. At the municipal level, the probability of tuberculosis diagnosis in EFs was associated with low primary care coverage, inequality, and social vulnerability. In some municipalities, more than 50% of the tuberculosis cases were diagnosed in EFs. Conclusions: In the state of São Paulo, one in every four tuberculosis patients is diagnosed in EFs, a diagnosis of tuberculosis in EFs being associated with poor treatment outcomes. At the municipal level, an EF diagnosis of tuberculosis is associated with structural and socioeconomic indicators, indicating areas for improvement.

Introduction: The University Hospital is reference in the city of Rio Grande, in the State of Rio Grande do Sul, Southeast part of Brazil, for chronic lung disease patients, with a major smoking cessation program. Aim: The purpose of this work was to analyze the utilization of Fagerström Tolerance Questionnaire to assess the nicotine dependence of smoking patients with reference to individualization of treatment. Material and Method: The authors used the Fagerström Tolerance Questionnaire (FTQ) in daily smoking adult patients from the Medical Clinic and Chest Medicine Units of the University Hospital and Rio Grande Santa Casa Hospital, during the period of one year. Three hundred and one valid questionnaires were filled out, 40.5% by females and 59.5% by males. Mean age was 48.6 years. The score of the questionnaires classified patients by dependence into five degrees: very low, low, medium, high, and very high. Results: 54.9% belong to the group of high nicotine dependence (score ³ 6), with a significant correlation of elevated nicotine dependence and cigarettes per day or time to the first cigarette of the day (p < 0.001). Conclusion: The use of the FTQ demonstrated ease of administration and more than 50% of the patients with a degree of chemical dependence that anticipate discomfort at cessation of smoking and need of treatment to control the withdrawal symptoms.

Asthma is characterized by variable airflow obstruction, hyperresponsiveness of airways to endogenous or exogenous stimuli and inflammation. Inadequacy of the techniques to use different inhalation devices is a cause of no response to treatment. The main purpose of this study was to evaluate how 20 medical students, 36 resident physicians on Internal Medicine/Pediatrics, and 40 asthma patients used three devices for inhalation therapy containing placebo. All patients were followed at the Pulmonary Outpatient Service of Botucatu Medical School and had been using inhaled medication during the last six months. The following devices were evaluated: metered dose inhalers (MDI), dry powder inhalers (DPI), and MDI attached to a spacer device. A single observer applied a protocol containing the main steps necessary to obtain a good inhaler technique to follow and grade the use of different devices. Health care professionals tested all three devices and patients tested only the device being used on their management. MDI was the device best known by doctors and patients. MDI use was associated with errors related to the coordination between inspiration and device activation. Failure do exhale completely before inhalation of the powder was the more frequent error observed with DPI use. In summary, patients have not been receiving repeated instruction on how to use inhaled medication and health care professionals are not well prepared to adequately teach their patients.

Objective: To evaluate how pulmonologists view the impact that asthma and COPD has on their patients, as well as how they treat these diseases. Methods: Survey including 227 pulmonologists participating in the VI Brazilian Congress on Asthma, II Brazilian Congress on COPD and II Brazilian Congress on Smoking, all of which were held in 2007. Results: According to the answers given by the pulmonologists, COPD is a public health problem of equal or greater importance than asthma, and COPD causes various disruptions in the lives of patients and their family members. When prescribing an inhalation device, pulmonologists feel that simplicity of use is more important than is the cost. There was a slight preference for the Aeroliser® and Diskus® systems. The budesonide-formoterol combination was the therapeutic regimen most often cited for the continued treatment of symptomatic asthma, whereas tiotropium bromide was the most often cited medication for the treatment of COPD. Selection of the therapeutic regimen for asthma and COPD is primarily influenced by the results of therapeutic trials published in the literature. Conclusions: The opinions of pulmonologists on the topics under study are in concordance with data in the specialized literature.

Introduction: Since 1981 the State Health Office has taken over the treatment and hospitalization of all tuberculosis cases in the State of São Paulo, southeastern Brazil. A decrease in both the incidence and the percentage of admissions due to tuberculosis has been observed during this period. Objective: To analyze the evolution of the reasons that led tuberculosis patients to hospitalization and correlate these reasons with hospitalization length and the type of discharge. Material and methods: A sample of 1,805 patients' records compiled between 1981 and 1995 at five tuberculosis hospitals in the State of São Paulo was reviewed. Results: The main reason for admission was general poor health, followed by cachexy. Increasing alcoholism was also observed. Among those who stayed in hospital for less than one week, the most frequent reasons for hospitalization were "other pathologies" and "respiratory insufficiency". These cases also showed the shortest average hospitalization length whereas the longest was presented by the patients admitted for social reasons and treatment failure. The patients with respiratory insufficiency presented the highest rate of dropouts and death. The highest rate of requested discharge was observed among the patients admitted due to drug intolerance whereas those admitted due to social reasons and alcoholism showed the highest rate of disciplinary release. The hospital that admitted females was the one with the highest rate of requested release, whereas in the hospitals that admitted males disciplinary release and dropouts were the most frequent types of discharge.

Objective: To evaluate the association between adherence to treatment and mortality among Chronic Obstructive Pulmonary Disease (COPD) patients treated in the Brazilian public health system. Methods: This is cohort study of moderate-to-severe COPD patients monitored in a public pharmaceutical care-based Disease Management Program (DMP). All subjects who died one year after the beginning of the cohort were age-matched with those who remained alive at the end of the cohort period. Treatment adherence was measured through pharmacy records. Patients who received at least 90% of the prescribed doses were considered adherent to treatment. Results: Of the 333 patients (52.8% age = 65 years, 67.9% male), 67.3% were adherent to treatment (adherence rate, 87.2%). Mortality was associated with lack of adherence (p = 0.04), presence of symptoms (mMRC = 2) and COPD treatment use. The death was associated with non-adherence, presence of symptoms and previous hospitalization. After adjustment, non-adherent patients to treatment were almost twice times likely to die compared to those adherents (Hazard Ratio (HR) 1.86; CI 1.16-2.98, p = 0.01). Conclusion: Non-adherence to treatment was associated with higher mortality among moderate-to-severe COPD patients treated in the Brazilian public health system. Strategies to monitor and optimize adherence should be strengthened to reduce COPD-related mortality.

Objective: Although COPD is a prevalent disease, it is undertreated, and there are no available data regarding previous treatment of COPD in Brazil. This study aimed to determine the appropriateness of maintenance treatment in COPD patients prior to their hospitalization and to identify variables associated with inappropriate treatment. Methods: This was an observational, cross-sectional, analytical study involving 50 inpatients with COPD at two hospitals in the city of Florianópolis, Brazil. The patients completed a questionnaire on parameters related to the maintenance treatment of COPD. Non-pharmacological management and pharmacological treatment were assessed based on the recommendations made by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) in 2011 and by the Brazilian National Ministry of Health in the chronic respiratory diseases section of its Caderno de Atenção Básica (CAB, Primary Care Guidebook). Results: In most of the patients, the COPD was classified as being severe or very severe. Regarding non-pharmacological management, 33% of the patients were smokers, only 32% had been advised to receive the flu vaccine, 28% had received pneumococcal vaccine, and only 6.5% of the patients in the B, C, and D categories received pulmonary rehabilitation. Regarding GOLD and CAB recommendations, pharmacological treatment was inappropriate in 50% and 74% of the patients, respectively. Based on GOLD recommendations, 38% were undertreated. A low level of education, low income, not receiving oxygen therapy, and not receiving the flu vaccine were associated with inappropriate treatment. Conclusions: The application of various non-pharmacological management recommendations was unsatisfactory. Regarding the GOLD recommendations, the high rate of inappropriate maintenance treatment was mainly due to undertreatment. In Brazil, even in severe COPD cases, optimizing treatment to achieve greater benefits continues to be a challenge.

Objective: To assess and compare the prevalence of comorbidities and risk factors for cardiovascular disease (CVD) in COPD patients according to disease severity. Methods: The study included 25 patients with mild-to-moderate COPD (68% male; mean age, 65 ± 8 years; mean FEV1, 73 ± 15% of predicted) and 25 with severe-to-very severe COPD (males, 56%; mean age, 69 ± 9 years; mean FEV1, 40 ± 18% of predicted). Comorbidities were recorded on the basis of data obtained from medical charts and clinical evaluations. Comorbidities were registered on the basis of data obtained from medical charts and clinical evaluations. The Charlson comorbidity index was calculated, and the Hospital Anxiety and Depression Scale (HADS) score was determined. Results: Of the 50 patients evaluated, 38 (76%) had been diagnosed with at least one comorbidity, 21 (42%) having been diagnosed with at least one CVD. Twenty-four patients (48%) had more than one CVD. Eighteen (36%) of the patients were current smokers, 10 (20%) had depression, 7 (14%) had dyslipidemia, and 7 (14%) had diabetes mellitus. Current smoking, depression, and dyslipidemia were more prevalent among the patients with mild-to-moderate COPD than among those with severe-to-very severe COPD (p < 0.001, p = 0.008, and p = 0.02, respectively). The prevalence of high blood pressure, diabetes mellitus, alcoholism, ischemic heart disease, and chronic heart failure was comparable between the two groups. The Charlson comorbidity index and HADS scores did not differ between the groups. Conclusions: Comorbidities are highly prevalent in COPD, regardless of its severity. Certain risk factors for CVD, themselves classified as diseases (including smoking, dyslipidemia, and depression), appear to be more prevalent in patients with mild-to-moderate COPD.
