Breath-actuated INhalation TheRapy: survey of phySicians' PErCepTion (INTROSPECT) in Nepal.

OBJECTIVE: Breath-actuated inhalers (BAIs) are gaining attention in the management of obstructive airway diseases (OADs). In Nepal, a BAI containing fluticasone propionate/salmeterol (FPS) has been available for a year. This survey is aimed at determining the perception and experience of physicians in Nepal concerning BAIs. METHODS: A cross-sectional, questionnaire-based survey was conducted. A total of 141 physicians participated and filled the survey. RESULTS: Most physicians felt that the right device should be easy to teach, learn and remember. They considered coordination and multiple steps as the primary challenges with pressurized metered-dose inhalers and dry powder inhalers, respectively. Most of them agreed that BAIs could address these challenges. BAIs were not only preferred by most of the physicians for asthma and chronic obstructive pulmonary disease but were also the preferred choice in newly diagnosed patients. Physicians believed that if current patients were shifted to BAIs, it could improve inhalation technique (88%) and compliance/adherence (81%). Almost all of them (92-97%) agreed that teaching the breathing technique and the cleaning process was easier and faster in BAIs. BAIs were considered easy and simple to use. Also, BAI's dose-counter helps patients to increase adherence to inhalation therapy. CONCLUSIONS: In this INTROSPECT survey, physicians in Nepal believed that BAIs could address the key challenges faced with using pMDIs and DPIs in asthma and COPD patients.

Understanding Practice Patterns of COPD: A Survey of Physicians in Nepal, Sri Lanka and Malaysia.

INTRODUCTION: There is much recent data from Nepal, Sri Lanka and Malaysia that can help us understand the practice patterns of physicians regarding the diagnosis and management of chronic obstructive pulmonary disease (COPD) in these countries. We conducted this survey to understand the practice patterns of physicians related to the diagnosis and management of COPD in these three countries. METHODS: This questionnaire-based, observational, multicentre, cross-sectional survey was carried out with 438 randomly selected physicians consulting COPD patients. RESULTS: In the survey, 73.29% of the physicians consulted at least five COPD patients daily (all patients > 40 years of age). 31.14% of the COPD patients visiting their doctors were women. Among physicians, 95.12% reported that at least 70% of their patients were smokers. 34.18% of the physicians did not routinely use spirometry to diagnose COPD. Most physicians preferred a short-acting ß2-agonist (SABA) (28.19%) in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) Group-A and long-acting muscarinic receptor antagonist plus long-acting ß2-agonist/inhaled corticosteroids (LAMA + LABA/ICS) in both the GOLD Group-C (39.86%) and Group-D (72.89%) patients. A significant number (40.67%) of physicians preferred LABA/LAMA for their GOLD Group-B patients. A pressurised metered dose inhaler (pMDI) with or without spacer was the most preferred device. Only 23.67% of the physicians believed that at least 70% of their patients had good adherence (> 80%) to therapy. Up to 54.42% of the physicians prescribed inhalation therapy to every COPD patient. Also, 39.95% of the physicians evaluated their patients' inhalation technique on every visit. Up to 52.67% of the physicians advised home nebulisation to > 10% of patients, with nebulised SABA/short-acting muscarinic receptor antagonist (SAMA) being the most preferred management choice. Most physicians offered smoking cessation advice (94.16%) and/or vaccinations (74.30%) as non-pharmacological management, whereas pulmonary rehabilitation was offered by a smaller number of physicians. Cost of therapy and poor technique were the most common reasons for non-adherence to COPD management therapy. CONCLUSION: Awareness of spirometry can be increased to improve the diagnosis of COPD. Though physicians are following the GOLD strategy recommendations for the pharmacological and non-pharmacological management of COPD, awareness of spirometry could be increased to improve proper diagnosis. Regular device demonstration during each visit can improve the inhalation technique and can possibly increase adherence to treatment.

Knowledge, practice pattern and attitude toward asthma management amongst physicians from Nepal, Malaysia, Lebanon, Myanmar and Morocco.

OBJECTIVE: This survey aimed to understand the physicians' practice pattern and challenges faced while treating their patients with asthma in five countries-Malaysia, Nepal, Myanmar, Morocco and Lebanon. METHODS: Questionnaire-based data was gathered from internal medicine doctors (209), general practitioners (206), chest physicians (152) and pediatricians (58) from 232 locations from across the five countries. RESULTS: Of the 816 physicians, 374 physicians encountered at least 5 asthma patients daily. Approximately, 38% physicians always used spirometry for diagnosis and only 12% physicians always recommended Peak flow meter (PFM) for home-monitoring. Salmeterol/fluticasone (71%) followed by formoterol/budesonide (38%) were the most preferred ICS/long-acting beta2-agonists (LABA); Salbutamol (78%) was the most preferred reliever medication. 60% physicians said >40% of their patients were apprehensive to use inhalers. 72% physicians preferred a pressurized metered-dose inhaler (pMDI) to a dry powder inhaler (DPI) with only a third of them using a spacer with the pMDI. 71% physicians believed that using similar device for controller and reliever can be beneficial to patients. Skipping medicines in absence of symptoms (64%), incorrect inhaler technique (48%) and high cost of medication (49%) were considered as major reasons for non-adherence by most physicians. Incorrect inhaler technique (66%) and nonadherence (59%) were considered the most common causes of poor asthma control. CONCLUSIONS: There are opportunities to improve the use of diagnostic and monitoring tools for asthma. Non-adherence, incorrect inhaler technique and cost remain a challenge to achieve good asthma control. Asthma education, including correct demonstration of inhaler, can potentially help to improve inhaler adherence.

Pneumococcal disease burden from an Indian perspective: Need for its prevention in pulmonology practice.

Globally, pneumococcal diseases are a significant public health concern. They are preventable and frequently occur among older adults. Major risk factors for the disease are extremes of age, alcohol intake, smoking, air pollution, and comorbid conditions (diabetes, chronic obstructive pulmonary disease, chronic kidney disease, liver disease, and heart disease). Risk factors, coupled with limited disease-burden data and the emergence of antibiotics resistance, are hindering the effective management of the disease in older adults. Various global guidelines recommend pneumococcal vaccines for the prevention of pneumococcal diseases, as they reduce disease burden, hospitalization, and mortality rates among patients with comorbid conditions. Besides being an integral part of childhood immunization, these vaccines are advocated by various Indian healthcare bodies/groups for older and younger adults with certain medical conditions. The article presents an overview of the closed-door discussion by the Indian pulmonary experts on the scientific evidence and clinical practice followed for the prevention of pneumococcal disease in India.

Guidelines for Diagnosis and Management of Bronchial Asthma: Joint Recommendations of National College of Chest Physicians (India) and Indian Chest Society.

Bronchial asthma is an important public health problem in India with significant morbidity. Several international guidelines for diagnosis and management of asthma are available, however there is a need for country-specific guidelines due to vast differences in availability and affordability of health-care facilities across the globe. The Indian Chest Society (ICS) and the National College of Chest Physicians (NCCP) of India have collaborated to develop evidence-based guidelines with an aim to assist physicians at all levels of health-care in diagnosis and management of asthma in a scientific manner. Besides a systematic review of the literature, Indian studies were specifically analysed to arrive at simple and practical recommendations. The evidence is presented under these five headings: (1) definitions, epidemiology and impact, (2) diagnosis, (3) pharmacologic management of stable disease, (4) management of acute exacerbations, and (5) non-pharmacologic management and special situations. The modified grade system was used for classifying the quality of evidence as 1, 2, 3, or usual practice point (UPP). The strength of recommendation was graded as A or B depending upon the level of evidence.

Validation of the St. George's Respiratory Questionnaire in Nepal.

The St. George's Respiratory Questionnaire (SGRQ) is a standardized questionnaire for measuring impaired health and perceived well-being in chronic airway disease, but it is not available in the Nepali language. We translated the original SGRQ into Nepali and validated its use in 150 individuals aged 40 to 80 years with and without COPD.We also examined if the SGRQ could be used as a screening tool to identify individuals at risk for COPD. We translated the SGRQ following a standard protocol. The validation study was then conducted in both community and hospital-based settings in Nepal. We enrolled 100 participants from a community setting who were not actively seeking medical care, 50 of which met criteria for chronic obstructive pulmonary disease (COPD) (post-bronchodilator forced expiratory volume in 1 second [FEV1]/ forced vital capacity [FVC]<70%) and 50 who did not. We also enrolled 50 participants with an established diagnosis of COPD who attended outpatient pulmonary clinics. All participants completed the questionnaire. We used linear regressions to compare average SGRQ scores by disease status categories and by lung function values, adjusted for age, sex, height and body mass index (BMI).All 150 participants (mean age 59.8 years, 48% male, mean BMI 20.5 kg/m2) completed the SGRQ. In multivariable regression, the average SGRQ total score was 23.9 points higher in established cases of COPD and 18.1 points higher in community cases of COPD when compared to participants without COPD living in the community (all p<0.001). The SGRQ total score also increased by an average of 2.1 points for each 100 mL decrease in post-FEV1 (p<0.001). The area-under-the-curve for the SGRQ total score as a predictor of COPD was 0.77 (95% confidence interval [CI] 0.68 to 0.85) and the optimal cutoff to identify COPD was 33 points.We developed a Nepali-validated version of SGRQ, which correlated well with both disease status and severity.

DOTS centre at a tertiary care teaching hospital.

In April 2002 Directly Observed Treatment - Short course (DOTS) centre was established in Nepal medical college teaching hospital(NMCTH) by National tuberculosis centre(NTC) with the aim to expand the services of DOTS to the general population. In this communication, we describe the experience of establishing a DOTS centre at Nepal's one of the premier medical institute and discuss the lessons learned. Since April 2002 to July 2004 (28 months), patients diagnosed with tuberculosis were enrolled for the treatment at the NMC DOTS clinic. 103 patients were diagnosed as suffering from tuberculosis, of them 8 patients were transferred out and 95 patients were given treatment at NMC DOTS clinic. Forty Patients were sputum positive cases, out of which 35 were new sputum positive cases and 5 were relapsed patients.20 patients had sputum negative pulmonary tuberculosis and 35 patients were diagnosed as having extra pulmonary tuberculosis. Cure rate of 97.0% (34/35) were achieved in the new sputum positive cases and 92.0% (37/40) in overall sputum positive cases. Despite tremendous patient load at tertiary care facility, it is possible to achieve a good sputum conversion and cure rate, by using DOTS.

Sleep apnoea syndrome in Nepal.

Sleep apnoea syndrome is a well recognized entity. Sleep studies of diagnosed patients with sleep apnoea were analyzed to understand the clinical profiles of Nepalese patients with this disorder. Eighty nine patients were diagnosed to have sleep apnoea syndrome during the period of 15 months starting from November 2003. All these patients were subjected to a detailed clinical evaluation including symptoms, presence or absence of other risk factors and co-morbidities, general physical and systemic examination and relevant investigations before performing polysomnography. Clinical profiles of patients who were confirmed to have sleep apnoea syndrome with apnoea hypopnoea index (AHI) more than five were included in the study. Forty one patients (46.1%) were found to have mild disease (AHI 6-20), 22 patients (24.7%) had moderate disease (AHI 21-40) and 26 patients (29.2%) were found to have severe disease. The common symptoms were snoring, excessive daytime sleepiness, frequent awakenings, nocturia, and choking spells during sleep. Obesity was found to be the most important risk factor associated with sleep apnoea. Males having collar size more than 16 inches and females with collar size more than 14.5 inches were found to have an increased risk to develop this problem. Hypertension (66.3%), chronic obstructive pulmonary disease (43.2%) and cardiac diseases (19.1%) were the common co-morbidities associated with this disorder. Sleep apnoea syndrome is not an uncommon problem in Nepalese population. It could be the cause of various cardiovascular problems and may complicate patients with chronic obstructive pulmonary disease.

Transbronchial needle aspiration in the diagnosis of respiratory diseases.

Thirty-three patients were subjected to transbronchial needle aspiration during the routine diagnostic bronchoscopy. Of the 17 patients with submucosal diseases, Transbronchial needle aspiration (TBNA) had a yield of 88.2% as against 81.2% for bronchial biopsies, 54.5% for bronchial brush smears and 41.1% for bronchial aspirates. TBNA also had a good yield in endobronchially visible growths. Nine patients had mediastinal or hilar lymph nodes as evident in contrast enhanced CT scans. TBNA was attempted from eight lymph node sites in six patients with bronchogenic carcinoma and was positive for malignant cells from four of these sites, while normal lymphoid cells were obtained from the other four sites. TBNA could also diagnose the disease from the left hilar lymph node in one patient with sarcoidosis, an extra tracheal bronchogenic carcinoma in another patient and an extra bronchial metastasis in yet another patient where conventional bronchoscopic techniques failed. TBNA was found to be a safe, cost effective and valuable diagnostic tool in the diagnosis of pulmonary diseases.

Allergic bronchopulmonary aspergillosis--a case report.

A 24 years old male presented with recurrent symptoms of cough and breathlessness for 6 years but increased in past 6 months. Fleeting radiological opacities, peripheral eosinophilia and central type bronchiectasus in high resolution CT scan gave the suspicion of allergic bronchopolmonary aspergilosis. Confirmation of the diagnosis was done by skin prick and immunological tests. The patient showed an excellent response to oral prednisolone.
