Clinical standards for the diagnosis and management of asthma in low- and middle-income countries.

BACKGROUND: The aim of these clinical standards is to aid the diagnosis and management of asthma in low-resource settings in low- and middle-income countries (LMICs).METHODS: A panel of 52 experts in the field of asthma in LMICs participated in a two-stage Delphi process to establish and reach a consensus on the clinical standards.RESULTS: Eighteen clinical standards were defined: Standard 1, Every individual with symptoms and signs compatible with asthma should undergo a clinical assessment; Standard 2, In individuals (>6 years) with a clinical assessment supportive of a diagnosis of asthma, a hand-held spirometry measurement should be used to confirm variable expiratory airflow limitation by demonstrating an acute response to a bronchodilator; Standard 3, Pre- and post-bronchodilator spirometry should be performed in individuals (>6 years) to support diagnosis before treatment is commenced if there is diagnostic uncertainty; Standard 4, Individuals with an acute exacerbation of asthma and clinical signs of hypoxaemia or increased work of breathing should be given supplementary oxygen to maintain saturation at 94-98%; Standard 5, Inhaled short-acting beta-2 agonists (SABAs) should be used as an emergency reliever in individuals with asthma via an appropriate spacer device for metered-dose inhalers; Standard 6, Short-course oral corticosteroids should be administered in appropriate doses to individuals having moderate to severe acute asthma exacerbations (minimum 3-5 days); Standard 7, Individuals having a severe asthma exacerbation should receive emergency care, including oxygen therapy, systemic corticosteroids, inhaled bronchodilators (e.g., salbutamol with or without ipratropium bromide) and a single dose of intravenous magnesium sulphate should be considered; Standard 8, All individuals with asthma should receive education about asthma and a personalised action plan; Standard 9, Inhaled medications (excluding dry-powder devices) should be administered via an appropriate spacer device in both adults and children. Children aged 0-3 years will require the spacer to be coupled to a face mask; Standard 10, Children aged <5 years with asthma should receive a SABA as-needed at step 1 and an inhaled corticosteroid (ICS) to cover periods of wheezing due to respiratory viral infections, and SABA as-needed and daily ICS from step 2 upwards; Standard 11, Children aged 6-11 years with asthma should receive an ICS taken whenever an inhaled SABA is used; Standard 12, All adolescents aged 12-18 years and adults with asthma should receive a combination inhaler (ICS and rapid onset of action long-acting beta-agonist [LABA] such as budesonide-formoterol), where available, to be used either as-needed (for mild asthma) or as both maintenance and reliever therapy, for moderate to severe asthma; Standard 13, Inhaled SABA alone for the management of patients aged >12 years is not recommended as it is associated with increased risk of morbidity and mortality. It should only be used where there is no access to ICS.The following standards (14-18) are for settings where there is no access to inhaled medicines. Standard 14, Patients without access to corticosteroids should be provided with a single short course of emergency oral prednisolone; Standard 15, Oral SABA for symptomatic relief should be used only if no inhaled SABA is available. Adjust to the individual's lowest beneficial dose to minimise adverse effects; Standard 16, Oral leukotriene receptor antagonists (LTRA) can be used as a preventive medication and is preferable to the use of long-term oral systemic corticosteroids; Standard 17, In exceptional circumstances, when there is a high risk of mortality from exacerbations, low-dose oral prednisolone daily or on alternate days may be considered on a case-by-case basis; Standard 18. Oral theophylline should be restricted for use in situations where it is the only bronchodilator treatment option available.CONCLUSION: These first consensus-based clinical standards for asthma management in LMICs are intended to help clinicians provide the most effective care for people in resource-limited settings.

Challenges of Continuation of Exclusive Breast Feeding up to 6 Months in a Setting with High Exclusive Breast Feeding Rates Reported. Experience from Eastern Province of Sri Lanka.

BACKGROUND: According to the World Breastfeeding Trends Initiative, Sri Lanka ranked as number one and only country to achieve green status. Exclusive breastfeeding (EBF) for six months is current practice with a rate of 75.5% among 0-5 months. AIM: Identify factors contributing early cessation of breastfeeding in a single centre of Eastern province Sri Lanka. METHODS: A descriptive cross-sectional study conducted in Sammanthurai Medical officer of Health area. Consecutive mother-infant days with the infant ageing < 6 months were included from 25 public health midwife areas using an interviewer administered questionnaire. Missing values imputed using 'missForest' algorithm. RESULTS: The mean age of the sample was 28.4(SD ± 5.6). Of the 257 mothers recruited, 15(5.8%) were teenagers and 42(16.3%) > 35 years. 251(97.6%) had children 1-5 and 86(33.5%) were first born. 140 (54.5%) had tertiary education, 28 (10.9%).31(12.1%) were employed. EBF rates 0-6 months was 79.8% (n = 205). 239(93.0%) started breastfeeding within an hour. EBF was not associated with maternal age, birth order or income. 18 employed mothers and 186 unemployed mothers continued EBF. Regarding the factors associated with EBF, having a tertiary education (p < .001), being employed (p = .004) and having less than 3 children (p = .03) were associated with non-exclusive breastfeeding. Tertiary education was the significant predictor of non-exclusive breastfeeding in this population with an odds ratio of 4.50 (95% CI 1.331-15.215). CONCLUSION: Employment identified as a risk factor for early cessation of EBF needs well planned further research to overcome this practical issue. Also might need revision of workplace policies, establishment of lactation areas in office premises to overcome some of these issues.
