Objective: To evaluate the effects that a hand hygiene education program has on the compliance of health professionals in an ICU. Methods: This was a quasi-experimental study with an interrupted time-series design, conducted over a 12-month period: the 5 months preceding the implementation of a hand hygiene education program (baseline period); the 2 months of the intensive (intervention) phase of the program; and the first 5 months thereafter (post-intervention phase). Hand hygiene compliance was monitored by one of the researchers, unbeknownst to the ICU team. The primary outcome measure was the variation in the rate of hand hygiene compliance. We also evaluated the duration of mechanical ventilation (MV), as well as the incidence of ventilator-associated pneumonia (VAP) at 28 days and 60 days, together with mortality at 28 days and 60 days. Results: On the basis of 959 observations, we found a significant increase in hand hygiene compliance rates-from 31.5% at baseline to 65.8% during the intervention phase and 83.8% during the post-intervention phase, corresponding to prevalence ratios of 2.09 and 2.66, respectively, in comparison with the baseline rate (p < 0.001). Despite that improvement, there were no significant changes in duration of MV, VAP incidence (at 28 or 60 days), or mortality (at 28 or 60 days). Conclusions: Our findings indicate that a hand hygiene education program can increase hand hygiene compliance among ICU professionals, although it appears to have no impact on VAP incidence, duration of MV, or mortality.

Objective: To evaluate the effects of an outpatient education program in patients with uncontrolled asthma. Methods: This was an uncontrolled study evaluating an educational intervention and involving patients with uncontrolled asthma ≥ 14 years of age. The participants completed a questionnaire designed to assess the level of asthma control, the inhalation technique, and quality of life. All of the patients underwent pulmonary function testing, after which they participated in an education program consisting of one 45-min face-to-face session, followed by phone interviews at two, four, and eight weeks. The participants were reevaluated after three months. Results: Sixty-three patients completed the study. There was a significant improvement in the level of asthma control (p < 0.001). Of the 63 patients, 28 (44.4%) and 6 (9.5%) were classified as having partially controlled asthma and controlled asthma, respectively. The mean FEV1 was 63.0 ± 20.0% and 68.5 ± 21.2% of the predicted value prior to and after the educational intervention, respectively (p = 0.002), and all of the quality of life scores improved (p < 0.05 for all). The same was true for the proportion of patients prior to and after the educational intervention using the proper inhalation technique when using metered dose inhalers (15.4% vs. 46.2%; p = 0.02) and dry powder inhalers (21.3% vs. 76.6%; p < 0.001). The logistic regression analysis revealed that an incorrect inhalation technique identified during the first evaluation was independently associated with a favorable response to the educational intervention. Conclusions: This study suggests that an outpatient education program for asthma patients improves the level of asthma control, lung function parameters, and quality of life. An incorrect inhalation technique identified during the first evaluation was predictive of a favorable response to the educational intervention.

Objective: To describe the implementation of a Tele-ICU program during the COVID-19 pandemic, as well as to describe and analyze the results of the first four months of operation of the program. Methods: This was a descriptive observational study of the implementation of a Tele-ICU program, followed by a retrospective analysis of clinical data of patients with COVID-19 admitted to ICUs between April and July of 2020. Results: The Tele-ICU program was implemented over a four-week period and proved to be feasible during the pandemic. Participants were trained remotely, and the program had an evidence-based design, the objective being to standardize care for patients with COVID-19. More than 100,000 views were recorded on the free online platforms and the mobile application. During the study period, the cases of 326 patients with COVID-19 were evaluated through the program. The median age was 60 years (IQR, 49-68 years). There was a predominance of males (56%). There was also a high prevalence of hypertension (49.1%) and diabetes mellitus (38.4%). At ICU admission, 83.7% of patients were on invasive mechanical ventilation, with a median PaO2/FiO2 ratio < 150. It was possible to use lung-protective ventilation in 75% of the patients. Overall, in-hospital mortality was 68%, and ICU mortality was 65%. Conclusions: Our Tele-ICU program provided multidisciplinary training to health care professionals and clinical follow-up for hundreds of critically ill patients. This public health care network initiative was unprecedented and proved to be feasible during the COVID-19 pandemic, encouraging the creation of similar projects that combine evidence-based practices, training, and Tele-ICU.

Objective: To analyze the effectiveness of the Tuberculosis Control Program, in conjunction with the recently incorporated Family Health Program, in the city of Cáceres, Brazil, between 1999 and 2004. Methods: This was a descriptive epidemiological study, based on the registry of tuberculosis cases diagnosed and treated in Cáceres, according to the characteristics of the cases diagnosed, whether or not the protocol for diagnosis, treatment, and monitoring of patients was followed, as well as the type of health care facility involved. Results: The incidence of tuberculosis was reduced from 99.4 to 49.8 (per 100,000 inhabitants) between 1999 and 2004. The patients presented characteristics similar to those of patients from other regions of Brazil, with a predominance of males during their most economically productive years. Among the patients presenting pulmonary forms and treated via the Family Health Program, there was a reduction in the number of sputum smear microscopies performed at the moment of diagnosis (OR = 0.33; 95%CI: 0.16-0.66) and prior to discharge (OR = 0.32; 95%CI: 0.18‑0.59). The patients monitored via the Family Health Program presented a 16.4% lower cure rate than did those treated at the referral center, as well as being more likely to abandon treatment (OR = 2.93; 95%CI: 1.15-7.46) and to die (OR = 5.71; 95%CI: 1.85‑18.1). Conclusion: The decentralization of the treatment services to the family health clinics did not improve the treatment or monitoring of tuberculosis cases in the city of Cáceres.

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 prevalence, outcomes, and predictors of multidrug-resistant nosocomial lower respiratory tract infections (LRTI) in patients in an ICU. Methods: This was an observational cohort study involving patients with nosocomial LRTI (health care-associated pneumonia, hospital-acquired pneumonia, or ventilator-associated pneumonia). Data were prospectively collected between 2015 and 2019. The multidrug-resistant pathogens (MDRPs) identified in the isolates studied included resistant to extended-spectrum cephalosporin-resistant and carbapenem-resistant Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa, carbapenem-resistant Enterobacteriaceae, and methicillin-resistant Staphylococcus aureus at microbiological diagnosis. Results: During the study period, 267 patients in the ICU were diagnosed with LRTI, microbiological confirmation of LRTI having been obtained in 237. Of these, 146 (62%) had at least one MDRP isolate. Patients infected with MDRP were found to have poorer outcomes than patients infected with susceptible strains, such as prolonged mechanical ventilation (18.0 days vs. 12.0 days; p < 0.001), prolonged ICU length of stay (23.0 days vs.16.0 days; p < 0.001), and higher mortality (73% vs. 53%; p < 0.001) when compared with patients infected with susceptible strains. Hospital length of stay = 5 days (OR = 3.20; 95% CI: 1.39-7.39; p = 0.005) and prolonged use vasoactive drugs (OR = 3.15; 95% CI: 1.42-7.01; p = 0.004) were independent predictors of LRTI caused by MDRPs (LRTI-MDRP). The presence of LRTI-MDRP was found to be an independent predictor of death (OR = 2.311; 95% CI: 1.091-4.894; p = 0.028). Conclusions: Prolonged use of vasoactive drugs and prolonged hospital length of stay were independent predictors of LRTI-MDRP in this population of critically ill patients with very poor outcomes.

Objective: Knowledge of acute asthma management in children is a subject that has rarely been explored. The objective of this study was to assess the level of such knowledge among health professionals in the city of Recife, Brazil. Methods: This was a cross-sectional survey involving 27 pediatricians and 7 nurses, all with at least two years of professional experience, at two large pediatric teaching hospitals in Recife. The participants completed a self-administered multiple-choice questionnaire. Results: The pediatricians and nurses all possessed insufficient knowledge regarding the use of metered dose inhalers, nebulization, and types/doses of medications, as well as techniques for decontamination and disinfection of the equipment. Conclusions: Insufficient knowledge of acute asthma management in children can lead to less effective treatment in hospitals such as those evaluated here. Educational programs should be developed in order to minimize this problem.

Objective: To evaluate the relationship between the reduction in the number of asthma-related hospital admissions and the changes occurring after the intervention performed in the health care system of the city of Londrina, Brazil. Methods: In 2003, an intervention was performed in the local health care system (Family Health Clinics). The steps adopted were as follows: development of a protocol based on the III Brazilian Consensus on Asthma Management; access to free inhaled corticosteroids for patients; training of health professionals; and implementation of educational measures, especially for the community. The authorizations for hospital admissions of patients diagnosed with asthma alone between 2002 and 2005 in the city of Londrina were analyzed. Results: The mean age was 14.3 ± 0.5 years, without gender predominance. The number of hospital admissions fell more markedly in 2005 than in the previous years studied. This decline was more pronounced at the Family Health Clinics where professional training occurred earlier. The post-intervention (2004-2005) rate of asthma-related hospital admissions (120/100,000 inhabitants) was significantly lower than the pre-intervention (2002-2003) rate (178/100,000 inhabitants; p < 0.01). Conclusions: The admission curve showed a tendency toward a reduction after 2003, and, aside from the intervention performed, no other factors that would explain the results obtained were identified. The rate at which the number of hospital admissions decreased was in direct proportion to the length of time elapsed since the intervention (greater decreases over time). We conclude that the intervention performed in the local health care system was responsible for the data presented.

Objective: To describe treatment outcomes (cure, noncompliance or death) after the implementation of the Directly Observed Treatment, Short-course (DOTS) strategy for tuberculosis control in the city of São José do Rio Preto, Brazil, between 1998 and 2003. Methods: A descriptive study, based on secondary data (National Case Registry database, Tuberculosis Epidemiology database, and the 'Black Book' Registry), was conducted using a specific instrument. The data were analyzed using descriptive statistics. Results: After the implementation of the DOTS strategy, there was a decrease in noncompliance and case detection rates as well as an increase in cure and death rates. The increase in the number of tuberculosis-related deaths might be attributable to three factors: the predominance of the disease in individuals over 50 years of age, tuberculosis/HIV co-infection, and the presence of accompanying diseases. Conclusion: The implementation of the DOTS strategy strengthened the decentralization of the tuberculosis control plans as well as the integration of the Basic Health Care Clinic teams with the Tuberculosis Control Program team. Political commitment of the administrator to tuberculosis control, in conjunction with the policy of benefits and incentives, is essential for the sustainability of the DOTS strategy.

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.

Introduction: The patient with COPD has his global physical activity decreased due to a progressive worsening of the lung function resultant from any kind of physical effort he may perform. Pulmonary rehabilitation (PR) is used in the United States and Europe as an alternative therapy in COPD treatment. Objective: To evaluate the effectiveness of PR as an ancillary treatment for COPD. Patients and methods: 30 patients prospectively submitted to the PR program developed in six weeks with three weekly sessions. Evaluation included clinical history and complete physical examination, the six-minute walking distance test, maximum workload test for upper limbs, maximum load test for lower limbs, a questionnaire of effort perception, spirometry and analysis of blood gases. Results: Concerning spirometry and analysis of blood gases, pre and post PR program, no statistically significant change was observed (p > 0.05). Pre and post PR program, statistically significant values (p < 0.05) were observed in the decrease in effort perception and increase in functional physical capacity, maximum workload test for upper limbs and incremental test for lower limbs used to determine the maximum workload. Conclusions: The authors concluded that, in the group studied, the PR program increased the patients' physical capacity and maximum workload for upper limbs whereas no changes were observed in the data regarding spirometry and analysis of blood gases.

Background: Asthma education programs induce better asthma control and are one of main recommendations in guidelines. The programs recommendations should include a nurse in the educational team applying the structured program. The purpose of the intervention is to bring a change in the daily life of the patient and the family in order to improve disease control and quality of life. Aim: To standardize and apply a structured post-consultation model as part of multidisciplinary care in an educational program for asthmatic patients seen at the outpatient clinic of a public hospital, and to monitor the changes in asthma knowledge and quality of life. Methods: A longitudinal prospective study over six months with regular visits at four week intervals (total = 6 visits), conducted at the outpatient department of Unifesp/EPM/HSP, and the patients were included after signing a consent form. The asthma structured educational plan was conducted by a multidisciplinary team and addressed the following issues: what is asthma, relief and prevention medicines, daily report of symptoms and dyspnea score, training of the correct use of inhaled medication, discussion and actions regarding triggering factors and how to avoid them, and tips to recognize the signals of uncontrolled asthma. A standard questionnaire about general knowledge on asthma and a quality of life questionnaire were applied at the beginning, during the course, and at the end of the program. Results: 26 asthmatics were followed over six months and showed a statistically significant improvement in their identification and management of asthma skills as well as better quality of life indices. Conclusion: The model of care and the approach and training techniques were adequate and useful in the development of a structured educational program for socially deprived patients.

Objective: In ICU patients on mechanical ventilation (MV), ventilator-associated pneumonia (VAP) is a common infection. However, such infection can be prevented through oral care protocols. The objective of this study was to compare the efficiency of the use of chlorhexidine and oral hygiene protocols (brushing and clinical procedures) with that of the use of chlorhexidine alone (intervention group and control group, respectively) in decreasing the prevalence of VAP in patients ≥ 18 years of age admitted to the ICU and requiring MV. Methods: In this systematic review and meta-analysis, studies were identified through searches of various national and international databases, as well as of the gray literature, and were selected in accordance with eligibility criteria. Results: We evaluated six studies, involving a collective total of 1,276 patients. We classified the risk of bias as low in three studies, high in two, and uncertain in one; among the six risk domains evaluated, a low risk of bias was predominant in five. The results for random risks were similar in terms of direction and statistical magnitude-chi-square = 6.34; risk difference: −0.06 (95% CI: −0.11 to −0.02); I2 = 21%; p = 0.007. There was a decrease in the prevalence of VAP in the intervention group (n = 1,276) included in the meta-analysis. Conclusions: Protocols that include the mechanical removal of oral biofilm in combination with the use of chlorhexidine can reduce the incidence of VAP among ICU patients requiring MV.

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.

Objective: To investigate the completeness of tuberculosis control program records for the 2001-2005 period in the case registry database of the state of Espírito Santo, Brazil. Methods: A descriptive study using secondary data analysis. The following variables were studied: race/color; educational level, supervised treatment, sputum culture at treatment outcome, HIV status, smear sputum microscopy at the sixth month of treatment and treatment outcome. Results: Using technical parameters of the case registry database of the Brazilian National Ministry of Health regarding the percentage of completeness of data on the reporting forms, the tuberculosis database of the state of Espírito Santo can be classified as fair to excellent. The state of Espírito Santo has 78 cities, 8 of which are considered priorities for tuberculosis control. For the variables studied, the cities not considered priorities presented better completeness of records than did those considered priorities, the exception being the variable treatment outcome, for which the percentage of completeness was comparable among all of the cities. Conclusions: Since the cities that are considered priorities accounted for 70.2% of the total number of reports, the responsible officials in those cities should improve the quality of those reports in terms of the completeness of forms and the updating of data, which are fundamental to the reliability of epidemiological analyses. That will make it possible to plan activities aimed at the prevention and control of tuberculosis in the state.

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 evaluate health professionals working at a tertiary pediatric hospital in terms of their knowledge regarding the practical use of metered-dose inhalers. Methods: Practical and written tests on the use of metered-dose inhalers were applied to physicians, physical therapists, nurses and nursing assistants. A score from 0 to 10 was assigned to each evaluation, and median scores were calculated for each professional category. Questions with higher and lower correct values were identified, and a descriptive comparison was made regarding the performance of the various professional categories. Statistical analysis was performed using the Kruskal-Wallis method for comparison of medians. A sequential logistic multiple regression analysis was also performed. Results: A total of 30 resident physicians or interns in the pediatrics department, 23 attending physicians, 29 physical therapists, 33 nurses and 31 nursing assistants were evaluated. Resident physicians, physical therapists and attending physicians performed significantly better than did nurses and nursing assistants. Only resident physicians had a median score greater than 6. Conclusions: The health professionals evaluated, particularly the nurses and nursing assistants, who are directly involved in the practical use of metered-dose inhalers, possess insufficient knowledge regarding the use of such inhalers.
