In cases of infection with Influenza A (H5N1), the presence of both neutropenia and raised serum transaminase levels predicts a poor outcome. Oseltamivir treatment shows benefit, but treatment with corticosteroids is associated with an increased risk of death.
BackgroundEarly initiation of treatment is essential for treatment of avian influenza A/H5N1 viral infection in humans, as the disease can lead to rapid development of severe pneumonia which can result in death. Contact with infected poultry is known to be a significant risk factor for contraction of H5N1 infection. However, handling and encountering poultry are a part of most peoples' daily lives, especially in rural communities in Vietnam where epidemic outbreaks among poultry have been continuously reported. Enhancing proper knowledge relating to H5N1 and to the importance of early initiation of treatment are crucial. The aim of this study was to develop an effective educational program to enhance awareness of H5N1 and motivate people to access to health care earlier when H5N1 infection is suspected or likely.Methodology and Principal FindingsA study was conducted in two agricultural communities (intervention and control groups) in the Ninh Binh province in Vietnam, where epidemic outbreaks of avian influenza have recently occurred in birds. A unique educational intervention was developed and provided to the intervention group, and no intervention was provided to the control group. A knowledge, attitude and practice (KAP) survey was conducted in both groups with a face-to-face interview by trained local healthcare workers at time points before and after the educational intervention. KAP scores were compared between the different time points and between the groups. How educational intervention influenced awareness relating to H5N1 and accessibility of healthcare in the population was analyzed. The study indicated an increased awareness of H5N1 and increased reliance on local health care workers.ConclusionsThe novel educational program which was developed for this study impacted awareness of H5N1, and resulted in more people seeking early access to healthcare, and also resulted in earlier medical intervention for patients with H5N1 avian influenza infection in Vietnam.
Chronic obstructive pulmonary disease (COPD) is a major disease in Asia. However, how to manage specifically Asian COPD patients has not been proposed. Awareness of COPD is very low and underdiagnosis/undertreatment is common in Asian countries. Low utilization of pulmonary function test and inhalers is also a problem. Moreover, high smoking prevalence and air pollution are barriers to managing Asian patients with COPD. The relatively low body mass index of Asian patients with COPD can increase their risk for experiencing adverse effects from COPD drugs. Physicians should consider the unique features of Asian populations with COPD such as the high prevalence rates of bronchiectasis and tuberculosis‐destroyed lungs, biomass smoke exposure and parasitic infection.
BackgroundIncorrect use of inhalers is very common and subsequently leads to poor control of COPD. Among health care providers, pharmacists are in the best position to educate patients about the correct use of inhaler devices.ObjectiveThe objective of this study was to evaluate the impact of pharmacist-led training on the improvement of inhaler technique for COPD patients in Vietnam.Patients and methodsFor this pre- and post-intervention study, standardized checklists of correct use of metered-dose inhalers (MDIs) and dry powder inhalers (DPIs) were used to evaluate the inhaler technique. A scoring system (maximum score =8) was applied before and after training to guarantee assessment uniformity among pharmacists. Three methods including “face-to-face training”, “teach-back” and “technique reminder label” were used. After the baseline evaluation (T0), the inhaler technique was reassessed after 1 month (T1), 3 months (T2), 6 months (T3) and 12 months (T4).ResultsA total of 211 COPD patients participated in the study. Before the training, a high rate of errors was recorded. After the training, the percentage of patients using MDIs and DPIs perfectly increased significantly (p<0.05). The mean technique score for MDIs and DPIs improved from 6.0 (T0) to 7.5 (T3) and 6.9 (T4) and 6.7 (T0) to 7.6 (T3) and 7.2 (T4), respectively (p<0.05). The average training time was 6 minutes (T0) and 3 minutes (T3), respectively.ConclusionPharmacist-led comprehensive inhaler technique intervention program using an unbiased and simple scoring system can significantly improve the inhaler techniques in COPD patients. Our results indicated a 3-month period as the optimal time period between training and retraining for maintaining the correct inhaler technique. The training would be highly feasible and suitable for implementing in the clinical setting. Our model of pharmacist-led training should be considered as an effective solution for managing COPD patients and better utilization of health care human resources, especially in a developing country like Vietnam.
For a long time lung cancer was associated with a fatalistic approach by healthcare professionals. In recent years, advances in imaging, improved diagnostic techniques and more effective treatment modalities are reasons for optimism. Accurate lung cancer staging is vitally important because treatment options and prognosis differ significantly by stage. The staging algorithm should include a contrast computed tomography (CT) of the chest and the upper abdomen including adrenals, positron emission tomography/CT for staging the mediastinum and to rule out extrathoracic metastasis in patients considered for surgical resection, endosonography-guided needle sampling procedure replacing mediastinoscopy for near complete mediastinal staging, and brain imaging as clinically indicated. Applicability of evidence-based guidelines for staging of lung cancer depends on the available expertise and level of resources and is directly impacted by financial issues. Considering the diversity of healthcare infrastructure and economic performance of Asian countries, optimal and costeffective use of staging methods appropriate to the available resources is prudent.The pulmonologist plays a central role in the multidisciplinary approach to lung cancer diagnosis, staging and management. Regional respiratory societies such as the Asian Pacific Society of Respirology should work with national respiratory societies to strive for uniform standards of care. For developing countries, a minimum set of care standards should be formulated.Cost-effective delivery of optimal care for lung cancer patients, including staging within the various healthcare systems, should be encouraged and most importantly,tobacco control implementation should receive an absolute priority status in all countries in Asia.
