Objective: To determine the prevalence of latent and active TB among detainees in a prison hospital in Bahia, Brazil. Methods: A cross-sectional study with prospective data collection was carried out comprising 237 inmates in the Bahia State Prison Hospital between July 2003 and April 2004. A standardized questionnaire was applied and completed by medical students. The detainees were systematically submitted to the following tests: tuberculin skin test, chest X-ray (anteroposterior), sputum smear microscopy and culture for mycobacteria. The events of interest were active TB and latent TB. Results: The mean age of the participants was 36.6 years, and 89.9% were male. Smoking and alcohol consumption were reported by 70.0% and 43.9% of the inmates, respectively. A history of treatment for TB was reported by 11.3% of the inmates. Of the inmates evaluated, 36.3% reported cough and 31.4% reported expectoration. Other less common symptoms were asthenia (in 26.2%), weight loss (in 23.1%), loss of appetite (in 17.7%), fever (in 11.3%) and hemoptysis (in 6.7%). Of the 86 inmates tested, none presented positive HIV serology. The prevalence of latent TB was 61.5% (96 of the 156 inmates submitted to tuberculin skin tests), whereas that of active TB was 2.5% (6 of the 237 inmates evaluated). The presence of cough was a determinant of active TB (prevalence ratio = 8.8; 95% CI: 1.04-73.9; p = 0.025). Conclusions: Active and latent TB are highly prevalent among inmates hospitalized in the Bahia State Prison Hospital. Our findings justify the need to implement public policies specifically directed towards the control of TB in this population.

Objective: To describe the clinical characteristics, laboratory data, and clinical outcomes of patients with and without sepsis admitted to the ICU of a private hospital in the city of Salvador, Brazil, and to identify clinical variables related to a worse prognosis in those with sepsis. Methods: This was a longitudinal study including all patients admitted to the general ICU of the Hospital Português, in the city of Salvador, Brazil, between June of 2008 and March of 2009. At ICU admission, two groups of patients were identified: with sepsis and without sepsis. Epidemiological, clinical and laboratory data were collected, and the Acute Physiology and Chronic Health Evaluation II (APACHE II) score was calculated. Results: Of the 144 patients in the study, 29 (20.1%) had sepsis. Among the patients with sepsis, males accounted for 55.2%, the mean age was 73.1 ± 14.6 years, and the mean APACHE II score was 23.8 ± 9.1, compared with 36.3%, 68.7 ± 17.7 years, and 18.4 ± 9.5, respectively, among those without sepsis. There were significant associations between a diagnosis of sepsis and the following variables: APACHE II score; in-hospital mortality; ICU mortality; HR; mean arterial pressure; hematocrit level; white blood cell count; and antibiotic use. The use of life support measures and lower hematocrit levels were associated with a worse prognosis in the patients with sepsis. Conclusions: The patients diagnosed with sepsis presented worse clinical outcomes, probably due to their greater severity. Hematocrit level was the only variable that was a predictor of mortality risk in the patients with sepsis.

Abstract Objective: To determine the rate of adherence to treatment with inhaled corticosteroids in patients with severe asthma, to identify predictive factors for adherence and to evaluate the relationship between adherence to treatment and parameters of clinical and functional response. Methods: Prospective cohort study of patients enrolled in the Program for the Control of Asthma and Allergic Rhinitis in the state of Bahia, Brazil. The study comprised 160 patients with severe asthma, monitored for 180 days in order to evaluate adherence (dependent variable) to the prescribed inhaled corticosteroid. Independent variables were assessed at baseline and for a six-month follow-up period by means of interviews and the completion of a standardized questionnaire. Patients recorded the missed doses in a diary. Results: Of the 160 patients, 158 completed the study. Adherence rate was 83.8%. Of the 158 patients, 112 (70.9%) were considered adherent (cut-off point: 80% of prescribed doses administered). There was a significant association between asthma control and adherence to treatment. Predictors of poor adherence were adverse effects, living far from the referral center, limited resources to pay for transportation and dose schedule. Other factors, such as depressive symptoms, religion and economic status, were not associated with poor adherence. Conclusions: Adherence to asthma treatment was high and was associated with the clinical response to treatment, in a sample of patients with severe asthma enrolled in a public program that provides free medication and the assistance of a multiprofessional specialized team in a referral center.

Objective: To determine the prevalence and characteristics of smoking among inpatients at a university hospital, as well as to evaluate their motivation, interest, and need for help in quitting smoking. Methods: A prospective study involving inpatients treated between May of 2008 and April of 2009 on the cardiovascular disease wards at the Antonio Pedro University Hospital, located in the city of Niterói, Brazil. All inpatients were asked to complete a questionnaire designed to collect data regarding demographics, reasons for admission, and smoking status. The smokers also responded to additional questions regarding their smoking habits. The level of nicotine dependence was determined with the Fagerström Test for Nicotine Dependence. Results: Of the 136 inpatients who participated in the study, 68 (50.0%) were male. The mean age was 60.7 years. The prevalence of smoking was 13.2%. Among the 49 patients with coronary disease, 36 (73.5%) were smokers or former smokers. The majority of the patients presented with a high level of nicotine dependence and reported withdrawal symptoms during hospitalization. Although most smokers were motivated to quit smoking, they admitted that they needed help to do so. Conclusions: Because smoking is forbidden in the hospital environment and most inpatients who smoke are highly motivated to quit, health professionals should view the hospitalization period as an opportunity to promote smoking cessation.

Objective: To determine the main causes of hemoptysis and to classify this symptom, in terms of the amount of blood expectorated, in patients hospitalized at a referral hospital for pulmonology. Methods: The study included 50 patients with hemoptysis admitted to the pulmonology ward of a general hospital in the city of Recife, Brazil, between July of 2005 and February of 2006. The data of interest were analyzed and compared with those in the literature. Results: The most common cause of hemoptysis was infection-in 39 patients (78%)-mostly related to tuberculosis sequelae or active tuberculosis. Regarding the severity of hemoptysis, moderate hemoptysis, diagnosed in 28 patients (56%), was the most common. Conclusions: Our results suggest that all patients who present with hemoptysis should be investigated for infection.

Objective: To evaluate the use of venous thromboembolism (VTE) prophylaxis in a general hospital. Methods: A cross-sectional cohort study at the Hospital Nossa Senhora da Conceição, located in the city of Porto Alegre, Brazil, involving a random sample of patients admitted between October of 2008 and February of 2009. We included patients over 18 years of age and hospitalized for more than 48 h. The exclusion criteria were anticoagulant use, pregnancy, puerperium, and a history of thromboembolic disease. The adequacy of prophylaxis was evaluated in accordance with a protocol created by the Hospital and principally based on the American College of Chest Physicians guidelines, eighth edition. Results: We included 262 patients. The mean age was 59.1 ± 16.6 years. The most common risk factors were immobilization (in 70.6%), infection (in 44.3%), cancer (in 27.5%), obesity (in 23.3%), and major surgery (in 14.1%). The risk of VTE was classified as high and moderate in 143 (54.6%) and 117 (44.7%) of the patients, respectively. Overall, 46.2% of the patients received adequate prophylaxis, 25% of those with ≥ three risk factors for VTE and 18% of those with cancer, the differences between these last two groups and their counterparts (patients with < three risk factors and those without cancer) being statistically significant (p < 0.001 for both). Conclusions: Our data reveal that nearly all patients at our hospital were at risk for VTE, and that less than half received adequate VTE prophylaxis, which is in agreement with the literature. It is surprising that inadequate prophylaxis is more common in high-risk patients.

Objective: To evaluate the experience in diagnosing and treating malignant pleural mesothelioma (MPM) accumulated over 5 years in a tertiary public hospital. Methods: The medical charts of the patients diagnosed with MPM between January of 2000 and February of 2005 were evaluated retrospectively. Results: Of the 17 patients analyzed, 14 were male and 3 were female. The mean age was 54.1 years (range, 13-75 years). The biopsy specimens for histopathological examination were obtained through thoracoscopy in 9 patients (53%), Cope needle in 5 (29.5%), and open pleural biopsy in 3 (17.5%). The following histological types were identified: epithelial, in 14 patients (82%); sarcomatoid, in 1 (6%); and biphasic, in 2 (12%). The therapeutic approaches used were as follows: multimodal (pleuropneumonectomy and adjuvant radiotherapy and chemotherapy) in 6 patients (35%); chemotherapy and radiotherapy in 6 (35%); radiotherapy alone in 3 (17.5%); and chemotherapy alone in 2 (12%). The mean survival was 11 months (range, 1-26 months). Conclusions: In the cases studied, an integrated multidisciplinary approach was used, and a highly complex hospital infrastructure was available for the diagnosis and treatment of MPM, as recommended in the literature. However, the mean survival was only 11 months, reflecting the aggressiveness of the disease.

Patients with active tuberculosis (Tb) can be admitted to hospital due to other health problems, Tb not being the admission diagnosis. In this study, the authors analyzed 141 inpatients with Tb, notified to the São Paulo Hospital Central Control of Infectious Diseases, during the period of august, 1999 to April, 2001, trying to identify causes of admission, risk factors, and duration of hospitalization. Of the total number of patients, 63% were male and 37% female, mean age being 38 years-old. 28% were smokers, 23% were alcoholics, and 17% were drug addicts. 23% of them reported previous Tb. 42% were HIV positive. 54.6% of the patients presented pulmonary tuberculosis and 67.5% of them had positive sputum. 22% of the patients had side effects to Tb treatment during hospitalization, drug-induced hepatitis (65.7%) and gastric intolerance (25.7%) being the most frequent. 8.5% of the patients required intensive care, staying there for 11 days, and 54% of the patients stayed at an infirmary with respiratory isolation. 17.7% of the patients died in hospital and 52% due to Tb. The patients were hospitalized for 29 days and isolated for 18 days. Drug addicts and smokers patients had longer hospital stays. HIV positive patients who had positive sputum had the same hospitalization period as others.

Objective: To describe the epidemiological monitoring of exposure to tuberculosis in a hospital environment and to analyze the profile of the disease in a general teaching hospital. Methods: A descriptive and retrospective study of tuberculosis cases diagnosed between 2000 and 2006, with the determination of indicators of morbidity and mortality, which were compared with the general population of patients treated at the hospital and with the hospital employees who developed active tuberculosis. Results: There were 763 patients who were treated for active tuberculosis (mean, 109 patients/year), 481 (63.1%) of whom were male. Most of the patients were in the 30-59 year age bracket. Tuberculosis that was exclusively pulmonary or extrapulmonary predominated. However, among the hospitalized patients, the combination of pulmonary and extrapulmonary tuberculosis, as well as exclusively noninfectious tuberculosis, predominated. Comorbidities were more prevalent among the hospitalized patients and among those who evolved to death. Only 52.8% of the cases treated at the hospital were reported. The overall hospital indicators showed longer length of hospital stay and greater mortality among the patients with tuberculosis. The incidence and prevalence show that there was a high risk of exposure to tuberculosis in the hospital during the period studied. Conclusions: The proposed indicators can potentially help standardize epidemiological monitoring procedures for nosocomial tuberculosis, and the epidemiological profile described in this study can contribute to a better understanding of the situation of tuberculosis in Brazil.

Objective: To determine the frequency of smoking among hospitalized patients in a general hospital, and to evaluate their profile. Methods: A random representative sample of 111 patients, classified as nonsmokers, former smokers or smokers, was evaluated. The smokers were submitted to the Fagerström test and measurement of expired carbon monoxide. Expired carbon monoxide higher than 6 ppm was considered a significant indicator of recent smoking. Results: Of the 111 patients in the sample, 60 (54%) were female. The mean age was 70 years. Of the 111 patients, 56 (51%) had never smoked, 36 (32%) were former smokers, and 19 (17%) were smokers. All of the smokers were male. The smokers were younger (58 ± 17 years) than the nonsmokers (68 ± 12 years) and the former smokers (73 ± 14 years)-ANOVA: F = 6.57 (p = 0.002). Among the smokers, the mean tobacco intake was 43 pack-years and the mean Fagerström score was 5.0. Of the 19 smokers, 11 (58%) had respiratory symptoms and 3 had withdrawal symptoms. The mean expired carbon monoxide in the smokers was 5.0 ppm. Expired carbon monoxide levels were higher than 6 ppm in 8 (42%) of the smokers. There was a higher prevalence of smokers in some wards: 70% of all smokers were hospitalized on only five wards. Conclusions: In a large tertiary hospital, 17% of the hospitalized patients were smokers, and 7% had smoked within the last 8 h. The smokers were younger men, hospitalized on specific wards.

Objective: To analyze the complications related to flexible bronchoscopy (FB) and its collection procedures in outpatients and inpatients with various lung and airway diseases treated at a university hospital. Methods: This was a retrospective analysis of complications occurring during or within 2 h after FB performed between January of 2012 and December of 2013, as recorded in the database of the respiratory endoscopy department of a hospital complex in the city of São Paulo, Brazil. Results: We analyzed 3,473 FBs. Complications occurred in 185 procedures (5.3%): moderate to severe bleeding, in 2.2%; pneumothorax, in 0.7%; severe bronchospasm, in 0.8%; general complications (hypoxemia, psychomotor agitation, arrhythmias, vomiting, or hypotension), in 1.6%; and cardiopulmonary arrest, in 0.03%. There were no deaths related to the procedures. Specifically, among the 1,728 patients undergoing biopsy, bronchial brushing, or fine-needle aspiration biopsy, bleeding occurred in 75 (4.3%). Among the 1,191 patients undergoing transbronchial biopsy, severe pneumothorax (requiring chest tube drainage) occurred in 24 (2.0%). Conclusions: In our patient sample, FB proved to be a safe method with a low rate of complications. Appropriate continuing training of specialist doctors and nursing staff, as well as the development of standardized care protocols, are important for maintaining those standards.

The authors conducted a cross-sectional survey to estimate the prevalence of tuberculosis infection in employees at the Uberlândia University Hospital, Minas Gerais. The participants (167) were classified according to exposure to tuberculosis into three groups: A) clinical medicine ward, frequent; B) admission unit, limited; and C) administration area, none, and underwent a two-step tuberculin testing. Factors associated with positive results were: level of exposure (44.70%; OR, 1.45; IC, 1.13-2.15; p = 0.013), age over 40 years (52.60%; OR, 1.66; IC, 1.20-2.30; p = 0.004) and employed for more than 10 years (59.30%; OR, 1.63; IC, 1.13-2.22; p = 0.011). Among clinical personnel at the Uberlândia University Hospital the prevalence of significant tuberculin reaction was high.

Mycobacterium tuberculosis is one of the most successful human pathogens. Highly virulent strains, which are more easily transmitted than are less virulent strains, elicit variable immune responses. We evaluated the Th1 responses (IFN-γ production) in healthy volunteers after stimulation with various strains. Our results show that the individuals with negative tuberculin skin test (TST) results were not necessarily naive to all of the strains tested, whereas individuals with positive TST results did not respond to all of the strains tested. Drug-resistant strains induced a lower mean level of IFN-γ production than did drug-sensitive strains. One possible practical application of this finding would be for the prediction of responses to treatment, in which it might be advantageous to have knowledge of the estimated IFN-γ production elicited by a specific isolated strain.

Objective: To determine the impact that implementing a combination of a computer-based clinical decision support system and a program of training seminars has on the use of appropriate prophylaxis for venous thromboembolism (VTE). Methods: We conducted a cross-sectional study in two phases (prior to and after the implementation of the new VTE prophylaxis protocol) in order to evaluate the impact that the combined strategy had on the use of appropriate VTE prophylaxis. The study was conducted at Nossa Senhora da ConceiþÒo Hospital, a general hospital in the city of Porto Alegre, Brazil. We included clinical and surgical patients over 18 years of age who were hospitalized for ≥ 48 h. The pre-implementation and post-implementation phase samples comprised 262 and 261 patients, respectively. Results: The baseline characteristics of the two samples were similar, including the distribution of patients by risk level. Comparing the pre-implementation and post-implementation periods, we found that the overall use of appropriate VTE prophylaxis increased from 46.2% to 57.9% (p = 0.01). Looking at specific patient populations, we observed that the use of appropriate VTE prophylaxis increased more dramatically among cancer patients (from 18.1% to 44.1%; p = 0.002) and among patients with three or more risk factors (from 25.0% to 42.9%; p = 0.008), two populations that benefit most from prophylaxis. Conclusions: It is possible to increase the use of appropriate VTE prophylaxis in economically constrained settings through the use of a computerized protocol adhered to by trained professionals. The underutilization of prophylaxis continues to be a major problem, indicative of the need for ongoing improvement in the quality of inpatient care.

Objective: To describe the reasons smokers give for seeking smoking cessation treatment, correlating those reasons with sociodemographic characteristics, clinical data, stage of readiness to change, and severity of nicotine dependence. Methods: Between February of 2008 and February of 2009, we evaluated 53 smokers who were naive to smoking cessation treatment and sought such treatment at the psychoactive substance abuse outpatient clinic of a university general hospital. The instruments used in the study were as follows: a form for the collection of sociodemographic and clinical data; the Fagerström Test for Nicotine Dependence; the University of Rhode Island Change Assessment scale; and a questionnaire on the smoking habit. Results: The sample comprised 34 women and 19 men, with a mean age of 48.1 years. Most of the participants had less than 8 years of schooling, had tobacco-related diseases, started smoking during adolescence, had smoked for more than 20 years, and had high nicotine dependence. The decision to quit smoking was mainly influenced by advice from family members, and the decision to seek specialized smoking cessation treatment was influenced by physicians. Most of the men were in the contemplation stage of change, whereas the women tended to have a more balanced distribution of the stages (p = 0.007). The women had attempted to quit smoking more often than had the men (p = 0.017) and also had a higher level of nicotine dependence (p = 0.053). Conclusions: The findings of this study highlight the role of health professionals in the approach to smoking cessation and suggest the importance of interventions that are more targeted, in view of the differences between men and women.

Objective: To implement community-acquired pneumonia (CAP) guidelines at a public hospital in Brazil and to evaluate the impact of these guidelines on health care quality. Methods: A quasi-experimental study, with a before-and-after design, involving adult patients diagnosed with CAP and hospitalized between July of 2007 and October of 2008 in the general ward of the Marília School of Medicine Hospital das Clínicas, located in the city of Marília, Brazil. Results: During the study period, 68 patients were diagnosed with CAP: 48 before the implementation of the guidelines and 20 after their implementation. After the implementation of the guidelines, 85% of the cases were treated in accordance with the guidelines, and there was a significant increase in the use of antibiotic therapy for atypical bacteria in patients with severe CAP (6.3% vs. 75.0%; p < 0.001). Comparing the pre-implementation and post-implementation periods, we observed a trend toward a decrease in the mortality (35.4% vs. 15.0%; p = 0.09) and toward an increase in the recording of SpO2 in the medical charts of the patients (18% vs. 30%; p = 0.42). During the study period, the degree of severity was not recorded on the medical charts of most patients. In addition, the initiation of antibiotic therapy followed a pre-established schedule, regardless of the severity of the infection. Conclusions: This study showed that, although the development and implementation of CAP guidelines promoted the optimization of the treatment, there were no significant differences regarding the assessment of severity, SpO2 recording, or the initiation of antibiotic therapy. Therefore, strategies that are more effective are needed in order to modify variables related to the work of physicians and nurses.

Objective: To determine the prevalence of smoking and the frequency of smoking cessation counseling among patients at a university hospital, as well as to compare smokers and former smokers in terms of smoking history. Methods: A cross-sectional study involving 629 patients at the Federal University of Paraná Hospital de Clínicas, located in the city of Curitiba, Brazil. Results: Of the 629 patients, 206 (32.7%) were male, 76 (12.1%) were smokers, 179 (28.5%) were former smokers, and 374 (59.5%) were nonsmokers. The mean age of the patients was 49.9 ± 15.0 years (range, 18-84 years). Of the 76 smokers and 179 former smokers, 72 (94.7%) and 166 (92.7%), respectively, were questioned about tobacco use. Smoking history and degree of nicotine dependence were higher among the former smokers (p = 0.0292 and p = 0.0125, respectively). Gender, age at smoking initiation, physician inquiry about tobacco use, and smoking cessation counseling were comparable between the two groups. The smoking cessation rate was 0.70. The prevalence of heavy smoking varied by gender and by age bracket, being higher in males and in the 41-70 year age bracket. Conclusions: The smoking prevalence in this group of patients was lower than that reported for patients at another university hospital, for adults in Curitiba, and for adults in Brazil. The smoking cessation rate was higher in these patients than in the general population of Curitiba. Smokers and former smokers differed regarding age, smoking history, and degree of nicotine dependence. Heavy smoking and a moderate or high degree of nicotine dependence were not obstacles to smoking cessation.

This study was performed in 117 patients infected by HIV, admitted to a reference hospital, in a period of one year (from 10/1/95 to 9/30/1996). All patients were 15 years old or more and had their sputum collected for AFB research, by clinical indication. All the 117 collected samples were submitted to bacilloscopic examination and 116 to culture (due to contamination in one sample) and also drug susceptibility test in all the 39 isolated strains. The strains were evaluated by PNB and TCH tests, and sent to a reference laboratory to typify the specimens. The bacilloscopic examination was positive in 34.2% (40/117) of the samples. From the 39 isolated strains, three did not belong to the M. tuberculosis complex (M. avium intracellulare in two, and one not identified strain). The resistance rate attributed separately to the M. tuberculosis was 13.90% (5/36). Resistance was not found that could be attributed to a single drug and the combination responsible for the highest resistance rate was that of rifampicin and isoniazid. The primary and secondary resistance was 20% (4/20) and 9.1% (1/10), respectively. Among social-demographic and clinical aspects, drug resistance was just significantly associated to a larger number of previous hospitalization (p < 0.03). These data suggest an intrahospital possible transmission of MDR (multi drug resistant) strains, among patients infected by HIV.

The direct costs incurred in managing patients with poorly controlled asthma are high and educational programs could decrease these costs. Aim: The objectives of this study were to compare the direct cost of the implementation of an educational program for adult asthmatic patients with the cost of the usual care delivered to asthmatics by specialists. Methods: Five years ago, a six-month study demonstrated that an educational program improved clinical outcomes (22 in educational program-E and 20 patients in control group-C). Throughout the educational intervention period all cases of hospitalization, emergency and regular calls involving patients from both groups were recorded. The basis for the values utilized in the calculation of costs was the healthcare database of the Brazilian government (DATASUS). The overall medication cost/patient in both groups was based on the amount of medication taken during the month preceding the last call. The final values were converted into US dollars. Results: The mean direct cost/patient in the educational (E) and control (C) groups and the difference (Δ) between groups were: hospitalizations (C = US$ 183, E = 0, Δ = US$ 183); emergency calls (C = US$ 14, E = US$ 5, Δ = US$ 9); regular calls (C = US$ 10, E = US$ 24, Δ = -US$ 14); medication (C = US$ 124,3, E = US$ 195,6, Δ = -US$ 71,3). The total cost was US$ 33/patient in group C and US$ 224/patient in group E with an average cost saving of US$ 107/patient. Conclusion: The expenses with medication is higher in E group because the regular use of maintenance drugs, however the study suggested that the application of the asthma education program reduced the total direct costs of asthma.

Objective: To determine the morbidity and mortality related to respiratory diseases among adults attending a tertiary-care hospital in Nigeria. Methods: We carried out a retrospective study of 183 adult patients (> 15 years of age), diagnosed with respiratory diseases between November of 2006 and October of 2008 at the Federal Medical Centre in Ido-Ekiti, Nigeria. Results: Of the 183 patients enrolled in the study, 78 (42.6%) were male and 105 (57.4%) were female, the male:female ratio being 1:1.4. Respiratory diseases were predominant in the 25-44 year age bracket (37.2%) and lower socioeconomic class (81.4%). Pulmonary TB was the leading cause of morbidity (in 42.1%), followed by asthma (in 17.5%) and pneumonia (in 15.3%). Lung cancer was uncommon (in only 0.6%). Pulmonary TB was the leading cause of hospitalization for respiratory disease (in 32%). Pulmonary TB, asthma, pneumonia and pleural pathologies were more common in women, whereas COPD was more common in men. The most common comorbidity was HIV infection (in 11.5%). The overall mean length of hospital stay was 14 days. Overall mortality was 8.7%; 50% of the deaths were attributed to pulmonary TB, 25% were attributed to pleural disease, 12.5% were attributed to pneumonia, and 6.25% were attributed to acute exacerbation of COPD. Mortality was higher in women and in the 25-44 year age bracket. Conclusions: Pulmonary TB, asthma and pneumonia were the leading causes of respiratory disease-related morbidity. Pulmonary TB was the leading cause of respiratory disease-related mortality among the adult Nigerians evaluated. Therefore, these conditions should be given higher priority in patient care. In addition, antiretroviral therapy should be readily accessible and affordable to HIV-infected individuals.
