[International standards for tuberculosis management]

International Standards for TB Care describe the international accepted levels of care for TB patients and suspects. The basic principles are the same worldwide: early correct diagnosis, standardized treatment insuring support and supervision, monitoring of the treatment results and highlighting all the public health responsibilities. The Standards provide the possibility to adhere to policies and practices necessary for an efficient control of the disease by all factors involved, including private or other areas. The Standards do not intend to replace local guidelines, but are focused on the relationship between individual care and the control based on community intervention. The article presents briefly the standards for diagnosis and treatment and the responsibilities of public health domain.

Are physicians aware of obstructive sleep apnea in children?

BACKGROUND AND PURPOSE

Childhood obstructive sleep apnea (OSA) affects 1-3% of preschool children. If left untreated, it can result in serious morbidity including growth retardation, cor pulmonale, and neurocognitive deficits, such as poor learning and behavioral problems. Early recognition and treatment is important to prevent morbidity and sequela and to provide better quality of life both for the child and his or her family members. The purpose of this study was to elucidate the knowledge and attitude physicians have about pediatric OSA, using the Obstructive Sleep Apnea Knowledge and Attitudes in Children (OSAKA-KIDS) questionnaire.

PATIENTS AND METHODS

The first section of the OSAKA-KIDS questionnaire, which includes 18 items presented in a true-or-false format, was developed to assess the knowledge physicians have about pediatric OSA. The second section, including five items, was developed to assess attitudes and was measured on a five-point Likert scale ranging from 1 to 5.

RESULTS

A total of 230 questionnaires were completed by physicians: 138 (60.3%) pediatricians, 70 (30.5%) general practitioners and 21 (9.2%) pulmonologists. The mean total knowledge score was 66.7%. The knowledge score positively correlated with having sub-specialty training (r=0.205, P=0.002) and negatively correlated with having a higher degree (r=-0.283, P<0.001). The mean total attitude score was 3.4. The knowledge score positively correlated with the attitude score (r=0.27, P<0.001).

CONCLUSIONS

This study shows that among physicians there are deficits in knowledge about childhood OSA and its treatment. More focused educational programs are needed within medical schools and within pediatric residency and post-graduate training programs.

[Pneumonia awareness year, 2004: scientific impact through publications in Archivos de Bronconeumología]

Pneumonia is a common and potentially serious infectious disease. Morbidity and mortality rates continue to be high in spite of major advances and steady progress in diagnosis and treatment. The economic impact of the disease is also great. It is therefore necessary to enlist the public, primary care and emergency physicians, and public policy administrators to join forces to treat and prevent pneumonia for the common good. The annual incidence of pneumonia in the population over the age of 14 years is 1.6 to 2.6 episodes/1000 inhabitants. The mortality rate is 14.1 per 100,000 inhabitants, and the associated costs are 115 million euros annually. The RESPIRA Foundation and the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) declared 2004 to be pneumonia awareness year with the aim of coordinating efforts to raise awareness, distribute information, and foster debate.

Combination of interventional pulmonology techniques (Nd:YAG laser resection and brachytherapy) with external beam radiotherapy in the treatment of lung cancer patients with Karnofsky Index < or =50

PURPOSE

To compare Nd: YAG laser resection with Nd: YAG laser plus brachytherapy and external beam radiotherapy (EBRT) in the palliation of malignant central airway obstruction symptoms due to lung cancer.

PATIENTS AND METHODS

In this prospective non-randomized study we evaluated the effects of Nd:YAG laser photoresection alone vs. Nd:YAG laser resection in combination with brachytherapy and EBRT on cough, dyspnoea, thoracic pain, haemoptysis, body weight loss, atelectasis, postobstructive pneumonia, endoscopic findings, disease-free period and survival rate in lung cancer patients. Only patients with Karnofsky index (KI) < or =50 were included. Sixty-four patients were divided into 2 groups: group I patients ( = 20) were treated only with Nd: YAG laser, and group II patients (n = 44) were treated with Nd: YAG laser followed by brachytherapy and EBRT.

RESULTS

Group I patients showed statistically significant improvement in all investigated parameters but cough. Group II patients achieved significant improvement in all investigated parameters. Comparative statistical analysis between the 2 groups revealed statistically significant improvement in group II with regard to dyspnoea, haemoptysis, KI and atelectasis. No significant improvement in group II was seen when other investigated parameters were considered. Disease-free period and survival rate were significantly longer in group II (p< or =0.0005).

CONCLUSION

The combination of interventional pulmonology procedures with standard modalities is the best option for the treatment of selected lung cancer patients.

Appropriateness of Hospital Admissions to a Pulmonology Department

OBJECTIVES

To analyze the rate of inappropriate admissions to a pulmonology department over the period of a year and to establish the reasons for such admission and predictors.

PATIENTS AND METHODS

All 2004 admissions to the pulmonology department of the Hospital de Valme were analyzed using a version of the Appropriateness Evaluation Protocol (AEP) developed for concurrent review. Two physicians who were not directly involved in admitting the patients performed the review. A logistic regression analysis was performed in order to identify the independent predictors of inappropriate hospital admission.

RESULTS

Of the 633 admissions analyzed, 92.1% (n = 583) were appropriate and 7.9% (n = 50) were inappropriate. The main reason for considering an admission to be inappropriate was that the patients in question could have been managed as outpatients (70%), whereas appropriate admissions were most frequently justified by the need for parenteral treatment (76.3%) or respiratory therapy (62%). In the logistic regression analysis, the variables that were independently associated with inappropriate admission were nonurgent admission (odds ratio, 2.82; 95% confidence interval, 1.28-6.21; P = .01), and a neoplasia diagnosis as the reason for admission (odds ratio, 8.57; 95% confidence interval, 2.69-27.24; P < .0005).

CONCLUSIONS

The rate of inappropriate hospital admissions was lower than that reported in other studies. Most inappropriate admissions were of patients who could have been managed as outpatients. An admission diagnosis of neoplasm and nonurgent admission were independent predictors of inappropriateness.

[Extrapulmonary tuberculosis at "Benéfico Jurídico" hospital in the 1999-2003 period]

A retrospective and descriptive study was conducted on patients diagnosed with extrapul-monary tuberculosis and discharged from "Benéfico Juridico" neumological hospital in the 1999-2003 period. The objective was to describe the perfor-mance of this disease. As a result, it was find out that of a total number of 353 diagnosed patients, 14% had extrapulmonary tuberculosis, 58% of these patients were in the 35-54 years age group, being the average age 39 years. The most frequent clinical manifestation was pleural (81%) followed by ganglionic tuberculosis (15%). Sixty one percent of cases were diagnosed based on clinical indications. Only 8% of patients were diagnosed by isolation of tuberculosis bacillus in a Lowestein-Jensen culture.

Differences in the evaluation and management of exercise-induced bronchospasm between family physicians and pulmonologists

Previous studies have demonstrated that specialists and generalists differ in the evaluation and management of asthma especially in terms of use of objective testing. We speculated that there also may be differences in the diagnosis and management of exercise-induced respiratory complaints. An Internet survey was sent to samples of pulmonologists and family physicians. Our data suggests that pulmonologists are much more likely to order bronchoprovocation testing than family physicians, and family physicians are more likely to start any empiric therapy than perform bronchoprovocation testing when exercise-induced bronchospasm is suspected. These differences may lead to inaccurate or missed diagnoses and unnecessary morbidity.

Validity of asthma diagnoses recorded in the Medical Services database of Quebec

The goal of this study was to evaluate the validity of asthma diagnoses recorded in the Medical Services (physician billing) database of the Canadian province of Quebec. The predictive positive value (PPV) and predictive negative value (PNV) of two operational definitions of asthma based on diagnoses recorded in the database were evaluated. Patients 16-80 years old treated by a respiratory or a family physician in 2002 were selected from the database. The diagnosis derived from the Medical Services database was compared to the diagnosis written in the patient's medical chart. The PPV and PNV of the first operational definition based on one asthma diagnosis or more recorded in the database over a 1-year period were found to be 0.75 and 0.96 for respiratory physicians and 0.67 and 0.99 for family physicians, for patients 16-44 years old. The PPV increased to 0.78 for family physicians and to 0.77 for respiratory physicians when the second operational definition based on two diagnoses of asthma or more was used. Results tended to be lower for 45-80 years old patients. We conclude that diagnoses recorded in the Medical Services database of Quebec are valid to identify patients with asthma.

[Chemotherapy and survival in advanced non-small cell lung carcinoma: is pneumologists' skepticism justified?]

OBJECTIVE

Few studies have assessed whether the advantage chemotherapy has been shown to have in treating advanced non-small lung carcinoma in clinical trials is transferrable to normal health care activity. This could explain the skepticism of a large number of pneumologists towards this treatment. The objective of our study was to analyze prognostic factors related to survival and to see whether cytostatic treatment was an independent predictor.

PATIENTS AND METHODS

Patients enrolled in the study had been diagnosed with non-small cell carcinoma in stages IV or IIIB with pleural or N2-N3 involvement and with a performance status of 2 or below according to the Eastern Cooperative Oncology Group (ECOG). Survival was analyzed with regard to the following variables: age, sex, comorbidity, weight loss, laboratory test results, histological type, ECOG score, TNM staging, and treatment. The Student t test, the chi(2) test, the Kaplan-Meier method, the log-rank test, and Cox regression analysis were used in the statistical analysis.

RESULTS

We enrolled 190 patients (157 men and 33 women) with a mean (SD) age of 61.75 (10.85) years (range, 33-85 years). Of these patients, 144 received cytostatic treatment and 46 palliative treatment. The median survival was 31 weeks and was related to absence of weight loss (hazard ratio [HR], 1.73; 95% confidence interval [CI], 1.26-2.39; P=.001), cytostatic treatment (HR, 1.85; 95% CI, 1.25-2.76; P=.002), and ECOG score of 0 to 1 (HR, 2.84; 95% CI, 1.62-5.00; P=.0001). In patients with ECOG scores of 0 to 1, weight loss and treatment were significant prognostic factors. Survival in the ECOG 2 group was 15 weeks for patients undergoing cytostatic treatment and 11 weeks for patients with symptomatic treatment.

CONCLUSIONS

In normal clinical practice, chemotherapy significantly prolongs survival in patients with performance status of less than 2, more time being gained if there is no associated weight loss. We conclude that the reluctance shown by many pneumologists toward using this treatment is not entirely justified.

Management of Patients with Small Pulmonary Nodules: A Survey of Radiologists, Pulmonologists, and Thoracic Surgeons

OBJECTIVE

The objective of our study was to survey recommendations for the management of small pulmonary nodules found on helical CT from radiologists, pulmonologists, and thoracic surgeons.

MATERIALS AND METHODS

We surveyed 774 radiologists, 623 pulmonologists, and 101 thoracic surgeons. All are members of an associated Austrian scientific society and were asked for their recommendations in 13 hypothetical cases. Statistical analysis was focused on possible differences between medical specialities, residents and fellows, and male and female doctors and on a possible influence of the number of years in training or in medical practice.

RESULTS

Complete surveys were returned from 91 radiologists, 74 pulmonologists, and 12 thoracic surgeons. The most frequent recommendation from radiologists was follow-up, whereas the most frequent recommendation from pulmonologists and surgeons was biopsy. The most frequently advised CT follow-up period was 3 months. Whereas thoracic surgeons preferred video-assisted thoracoscopy, radiologists and pulmonologists recommended less invasive procedures (bronchoscopy, CT-guided biopsy) to gain a specific diagnosis.

CONCLUSION

There are significant differences in the management of small pulmonary nodules among radiologists, pulmonologists, and thoracic surgeons. Whereas radiologists tend to recommend short-term follow-up, pulmonologists and thoracic surgeons prefer a more aggressive approach, especially in patients with a higher likelihood of malignancy.

The cardiopulmonary system: research and training opportunities

The new biology has the potential to provide mechanistic insights into the causes and progression of complex cardiopulmonary diseases such as congenital heart disease and bronchopulmonary dysplasia. Such research requires collaborative investigation supported by sophisticated infrastructures and core facilities. Translating basic observations to clinical outcomes will require networks for collaborative translational research. The research initiatives require excellently trained and motivated clinician-scientists, but there are numerous barriers to the training and support of clinician-scientists in cardiology and neonatology.

How is difficult asthma managed?

Most patients with asthma can be easily treated. Some have difficult asthma; in some because the diagnosis is erroneous, in others because of comorbidity or noncompliance. A European Respiratory Society Task Force has called for an integrated approach for these patients, and positive results have been reported using protocols. In the UK, there is no overall understanding of the size of this problem, or how these patients are managed. A postal survey of 683 consultant members of the British Thoracic Society designed to elicit respondents' views on how they would manage four clinical scenarios was conducted. There was a 50.4% response rate. Few reported a uniform approach to the investigation of such patients. The availability of allied healthcare professionals was variable. The 21 consultant respiratory physicans, reporting a special interest in difficult asthma, were significantly more likely to objectively assess compliance, perform skin-prick tests and to utilise a liaison psychiatrist than those without an expressed special interest in asthma. Many reported difficulty in accessing psychologists, liaison psychiatrists and social workers. Approaches to the diagnosis and management of "vocal cord dysfunction" were variable. The results of this postal survey of specialist thoracic physicians in the UK suggest that a protocol for difficult asthma is not in widespread use and that access to necessary allied healthcare professionals is not uniform. Pulmonologists with a declared special interest in difficult asthma may have configured their services and approaches more in line with that proposed by the European Respiratory Society Task Force.

Influenza vaccination status and influenza-related perspectives and practices among US physicians

BACKGROUND AND OBJECTIVE

The influenza vaccination rate among US healthcare workers (HCWs) remains low. This survey was designed to assess influenza vaccination status and related knowledge, attitudes, and beliefs among a national sample of primary care physicians and subspecialists likely to see patients at high risk for complications from influenza.

METHODS

We used a mail survey of a national random sample of 495 family physicians (FPs), 491 internists (IMs), 498 geriatricians (GERs), and 497 pulmonologists (PUDs).

RESULTS

The overall response rate was 38%. Almost all respondents (87%) reported receiving an influenza vaccine during the 2003-2004 influenza season, with no significant difference across specialty groups (84% FPs, 87% IMs, 87% GERs, 91% PUDs). In a multivariate model, adjusted for physician specialty and age group, significant predictors of vaccination were: strong agreement that HCWs have professional responsibility to be vaccinated, access to vaccination on site and free of charge, strong worksite recommendation for HCWs to be vaccinated, and strong agreement that benefits of vaccination outweigh risk of side effects.

CONCLUSIONS

Physicians reported a high influenza vaccination rate. To improve these rates further, with likely benefits for other HCWs, worksite policies that facilitate access to vaccination and documentation of reductions in nosocomial influenza associated with HCW vaccination should continue to be pursued.
