Item Quality of care in the management of asthmatic children with regard to compliance with the guidelines in in-ward setting in a district of Sri Lanka: a descriptive study(College of Community Physicians of Sri Lanka, 2020) Abeysena, C.; Perera, N.INTRODUCTION: The quality of paediatric asthma management in the in-ward settings has not been assessed in Sri Lanka. OBJECTIVES: To describe the quality of care in the management of asthmatic children with regard to compliance with the guidelines. METHODS: A descriptive cross-sectional study was carried out in state hospitals with paediatric units in a district of Sri Lanka. A sample of 577 children diagnosed by a consultant paediatrician was selected. Eleven indicators were chosen by modified Delphi technique. Data collection instruments were an interviewer-administered questionnaire and a record sheet. Compliance with guidelines according to 11 indicators was expressed in percentages. RESULTS: The assessment of acute severity was 100%. The use of systemic corticosteroid at first prescription was 88.9% (n=513), whereas it was 69% (n=398) with oral steroid therapy and 54.5% (n=315) with long-term use of steroid inhaler. Assessment of chronic asthma severity was 31.2% (n=180). Caregivers who had received health education on triggering factors of asthma, on what to do during an asthma attack, and how to use the inhaler were 62.0% (n=358), 37.1% (214) and 68.8% (n=217), respectively. All patients have been issued a diagnosis card on discharge and among them, 74.4% (n=429)received a complete discharge summary and 90.6% (n=523) were scheduled for follow up appointments. CONCLUSIONS: Assessment of acute severity of asthma and the provision of diagnosis card on discharge were exceptional. Assessment of the severity of chronic asthma and providing health education for caregivers should be improved. Prescribing long term use of a steroid inhaler is to be revised. KEYWORDS: Children, Clinical, Indicators, Medication, PerformanceItem Knowledge on primary and secondary prevention of asthma among caregivers of asthmatic children admitted to paediatric wards in Gampaha District.(College of Community Physicians of Sri Lanka., 2019) Perera, N.; Abeysena, C.INTRODUCTION: Asthma is considered to be one of the major public health problems. The accurate knowledge of caregiver on asthma is important for the management. OBJECTIVES: To describe the knowledge on primary and secondary prevention of asthma among caregivers of asthmatic children admitted to the paediatric wards in the district of Gampaha. METHODS: A descriptive cross-sectional study was carried out among 577 caregivers of inward asthmatic children. Pre-tested interviewer- and self-administered questionnaires were used to assess the knowledge on asthma. The grand score of knowledge on asthma was calculated out of 34. The 75th percentile value was considered to differentiate ‘good’ knowledge from ‘poor’ knowledge. Multiple logistic regression was applied to determine the factors associated with poor knowledge on asthma. Results were expressed in adjusted odds ratio (aOR) and 95% confidence interval (CI). RESULTS: The mean score for knowledge on asthma was 20.6 (SD=4.42) ranging from 7 to 30. Among the caregivers, 369 (64%) had poor knowledge on asthma. Low educational level of the caregiver (aOR=2.48; 95% CI=1.59, 3.86) and being under prophylaxis treatment for less than one year (aOR=2.49; 95% CI=1.50, 4.13) were the determinants of poor knowledge on asthma. CONCLUSIONS: Majority of the caregivers’ knowledge on asthma was poor. The caregivers’ low educational level and shorter duration of prophylaxis treatment for the children were associated with poor knowledge on asthma.Item Effectiveness of providing health education to caregivers of hospitalized children with asthma for the prevention of recurrent attacks: a quasi-randomized trial(Informa Healthcare, 2020) Perera, N.; Abeysena, C.OBJECTIVE: To determine the effectiveness of health education intervention for caregivers of children with asthma, focused on preventing recurrent attacks and improving knowledge. METHODS: A quasi-randomized trial of 177 caregivers of asthmatic children was conducted in government hospitals in a district of Sri Lanka. At the time of discharge from the hospital, a health education booklet was prepared and given to the caregivers in the intervention group, along with individual explanation and discussion. The caregivers' knowledge of asthma and preventive practices was assessed. The primary outcome was the proportion of children with recurrent attacks of asthma who needed doctor visits during the three month post discharge period. The intention-to-treat principle was applied for data analysis.RESULTS: In comparison to the control group, the intervention group had a 76% significant reduction in visits to the doctor for recurrent attacks (95% CI:45%-90%) and a 75% significant reduction in hospital admissions required for asthmatic children (95% CI:16%-93%) at the end of three months of intervention. The mean score of knowledge of asthma in the intervention group was 1.73 units higher at three months (p < 0.01) and 1.47 units higher at six months (p < 0.01) than the control group. The mean score of preventive practices for asthma in the intervention group was 1.25 units higher at three months (p = 0.02) and 1.15 units higher at six months (p < 0.01) versus the control group.CONCLUSION: Health education intervention significantly decreased doctor and hospital visits at three months. In addition, caregiver knowledge of asthma and preventive practices also improved. TRIAL REGISTRATION NUMBER: SLCTR/2010/007.Item Association between functional abdominal pain disorders and asthma in adolescents: A cross-sectional study(Baishideng Publishing Group, 2018) Kumari, M.V.; Devanarayana, N.M.; Amarasiri, L.; Rajindrajith, S.AIM: To find the association between asthma and different types of functional abdominal pain disorders (FAPDs) among teenagers. METHOD : A cross-sectional study was conducted among 13 to 15-year-old children from six randomly selected schools in Anuradhapura district of Sri Lanka. Data were collected using translated and validated self-administered questionnaires (Rome III questionnaire, International Study on Asthma and Allergies in Childhood questionnaire, and Pediatric Quality of Life Inventory 4.0) and administered under an examination setting after obtaining parental consent and assent. RESULTS: Of the 1101 children included in the analysis, 157 (14.3%) had asthma and 101 (9.2%) had at least one FAPDs. Of children with asthma, 19.1% had at least one type of FAPDs. Prevalence rates of functional abdominal pain (FAP)(8.9% vs 3.3% in non-asthmatics), functional dyspepsia (FD) (2.5% vs 0.7%), and abdominal migraine (AM) (3.2% vs 0.4%) were higher in those with asthma (P < 0.05, multiple logistic regression analysis), but not in those with irritable bowel syndrome (4.5% vs 3.1%, P = 0.2). Severe abdominal pain (10.8% vs 4.6%), bloating (16.6% vs 9.6%), nausea (6.4% vs 2.9%), and anorexia (24.2% vs 16.2%) were more prevalent among asthmatics (P < 0.05). Lower gastrointestinal symptoms did not show a significant difference. Scores obtained for health related quality of life (HRQoL) were lower in those with asthma and FAPDs (P < 0.05, unpaired t-test). CONCLUSION: Asthma is associated with three different types of FAPDs, namely, FD, AM, and FAP. HRQoL is significantly impaired in teenagers with asthma and FAPDs.Item The Prevalence of asthma in Sri Lankan adults((Wiley Blackwell Scientific Publications, 2016) Amarasiri, D.L.; Undugodage, U.C.M.; Silva, H.K.M.S.; Sadikeen, A.; Gunasinghe, W.; Fernando, A.; Wickremasinghe, A.R.; Gunasekera, K.D.BACKGROUND AND AIMS: Data on adult asthma is scarce in Sri Lanka. The objective of this study was to estimate the prevalence of asthma and related symptoms amongst adults in the general population. METHODS: A multi-centered, cross-sectional study was conducted using an interviewer-administered translated version of the screening questionnaire of the European Community Respiratory Health Survey from June to December 2013 in 7 provinces of Sri Lanka. Subjects were selected randomly from different regions by stratified sampling. The prevalence of asthma was defined as "wheezing in the past 12 months (current wheeze)", 'self-reported attack of asthma in the past 12 months' or 'current asthma medication use'. RESULTS: The study comprised 1872 subjects (45.1% males, 48.8% aged18-45 years) of which 12.2% were current smokers. In the total population, the prevalence of current wheeze was 23.9% (95% CI: 22.0%-25.9%), of self-reported asthma was 11.8% (95% CI: 10.3%- 13.2%) and of current asthma medication use was 11.1% (95% CI: 9.6%- 12.5%). The prevalence of asthma according to a positive response to either of the above questions was 31.4% (95% CI: 29.3%-33.4%) The prevalence of symptoms was higher in adults aged >45 years. Of those with current wheeze, 60.9% denied a diagnosis of asthma and only 38.2% admitted to use of asthma medication. In those with current wheeze, wheezing was the only symptom in 19.9% whereas 80.1% had at least one other respiratory symptom (tightness of chest, cough or shortness of breath) of which cough was the most common symptom. In those without current wheeze, self-reported asthma and current asthma medication use, 30%, 35.9% and 36.6% respectively had at least one other respiratory symptom. CONCLUSIONS: The prevalence of asthma in Sri Lankan adults is high in comparison with global data. A significant percentage of symptomatic individuals deny having asthma and are not on medication.Item Prevalence and correlates of asthma among selected garment factory workers at the Free Trade Zone, Ekala(College of Community Physicians of Sri Lanka, 2015) Jayawardana, P.; Abeysena, C.Objective To determine prevalence of bronchial asthma (BA) and its correlates and respiratory functions among selected garment factory workers (GFW) at the Free Trade Zone, Ekala. Methods This consisted of a cross sectional descriptive and an analytical study. It was conducted at three selected garment factories and a clinic setting in Ekala. Study group for first component included 674 GFW who have worked for 1 or more years at the current garment factories. Control group for second component included 100 participants who have never worked in garment factories. Study instruments consisted of an interviewer administered questionnaire and spirometry. Bivariate analysis was followed by multiple logistic regressions. Results were expressed as odds ratios (OR) and 95% Confidence intervals (CI). Results Overall prevalence of BA among GFW was 32.3% (95% CI:28.8-36.0%). Prevalence of “probable occupational asthma” among asthmatic GFW was 49.5% (95% CI:42.7-56.4%). Being a GFW (OR=3.5, 95% CI:1.9-7.2) and age >30 years (OR=1.5; 95% CI:1.1-2.1) were significantly associated with prevalence of BA. Among GFW, FEV1.0 and PEFR were significantly lower among asthmatics compared to non asthmatics, and FVC, FEV1.0, and PEFR among those exposed to dust for >3 years compared to ≤3 years. Conclusions Prevalence of bronchial asthma was higher among Garment Factory Workers. However, respiratory functions were lower only among those who were asthmatics.Item The Prevalence of reflux oesophagitis in adult asthmatics(Wiley- Blackwell, 2009) Amarasiri, L.; Ranasinha, C.D.; de Silva, H.J.BACKGROUND/PURPOSE: Asthma and gastro-oesophageal reflux disease are known to be associated. The severity of asthma is related to the degree of reflux. This relationship has been little studied in South Asia. METHODS: Thirty asthmatics underwent a reflux symptom assessment using a validated questionnaire assessing 7 upper gastro-intestinal (UGI) symptoms graded on a 5-point Likert scale (Amarasiri LD 2009). They further underwent UGI endoscopy. RESULTS: All asthmatics had mild stable asthma. 20 of the 30 asthmatics had apositive GORD symptom score. 27 asthmatics consented to UGI endoscopy. The grade of oesophagitis was classified using Savary Miller criteria. 10 of the 27 asthmatics had evidence of mucosal damage (see Table 1). There was no correlation between the grade of oesophagitis and the GORD score (r = 0.025; P = 0.896, Spearman Rank correlation). CONCLUSIONS: The prevalence of reflux oesophagitis in asthmatics was 37%. There was no association of severity of oesophagitis with symptoms. Both these findings are consistent with the global data, but have not previously been described in a South Asian population.Item The role of reflux in the genesis of respiratory symptoms in a cohort of adult asthmatics in Sri Lanka(Wiley-Blackwell, 2010) Amarasiri, L.; Ranasinha, C.D.; Pathmeswaran, A.; de Silva, H.J.INTRODUCTION: The oesophagus and airways have a common origin. Reflux related respiratory symptoms may be triggered by aspiration of gastric refluxate into airways or a vagally mediated oesophago-tracheo-bronchial. This association has not been reported previously in Sri Lanka. The aim of this study was to describe the association between gastro-oesophageal reflux (GOR) events and respiratory symptoms in a cohort of adult asthmatics in Sri Lanka. METHODS: Thirty stable, mild asthmatics (American Thoracic Society criteria) underwent dual-sensor ambulatory oesophageal pH monitoring. Respiratory symptoms (cough, wheeze, difficult breathing, chest tightness) during monitoring were recorded and correlated with reflux events. RESULTS: Both proximal and distal GOR parameters were significantly higher in asthmatics than controls (P < 0.050; Mann–Whitney U-test). However, there was no difference in any parameter between asthmatics with and without respiratory symptoms. Abnormal proximal acid reflux was documented in 66.7% and distal reflux in 73.3% of 30 asthmatics. Of 102 respiratory symptoms in all asthmatics, majority (72%) were cough episodes. In total, 93% of coughs, 81% of wheeze and all of chest tightness was reflux-associated, where in most, reflux events preceded respiratory symptoms. Of 15 asthmatics with respiratory symptoms, acid exposure was normal in 4 (26%), abnormally high in proximal oesophagus in 9 (60%) and abnormally high in the distal oesophagus in 11 (73%) and abnormal at both levels in 8 (53%). Most reflux events in asthmatics occurred in the upright position. CONCLUSION: Asthmatics have more GOR and associated respiratory symptoms than non-asthmatic volunteers, with reflux episodes preceding respiratory symptoms in most cases. Distal GOR and upright acid exposure was more prominent than proximal GOR.Item Factors affecting the compliance of SLMA asthma prophylactic guidelines in children(Sri Lanka Medical Association, 2001) Karunasekera, K.A.W.; Perera, K.P.J.INTRODUCTION: Guidelines to use prophylactic drugs in childhood asthma were laid down by SLMA in 1995. Yet a fair number of children we come across in clinical practice are not on prophylactic agents, though they are indicated. OBJECTIVE: To determine the compliance with SLMA asthm a prophylactic guidelines among patients admitted with asthma and to determine the socio-demographic factors affecting compliance. METHODS: All consecutive admissions to the university paediatric unit, Ragama Hospital between January 1996 and February 1998 with asthma (356) were included. Children admitted several times during the study period were included only on the 1st admission. Diagnosis of asthma was made clinically by-a consultant paediatrician. Details regarding frequency of asthma, severity, sleep disturbances, number of admissions to hospital, school absenteeism and use of prophylactic agents were obtained together with socio-demographic data. Chi-squared test was used as the statistical test. RESULTS: Only 18.2% of 251 children for whom asthma prophylactics were indicated were using prophylactic agents. 67.3% had one indication, 28.3% had two and 3.98% had three indications to use prophylaxis. Older age, male sex and monthly income of more than Rs.lO,000/= were found as significant factors for adhering to SLMA guidelines for asthma prophylaxis (p<0.05). Parental education and occupation did not show any significant association with the use of prophylaxis (p>0.05). CONCLUSIONS: Among the children in this study, boys older children and children from households with a monthly income over Rs. 10,0007= were more likely to use prophylactics.Item Prevalence of asthma and atopy among primary school children(Sri Lanka Medical Association, 2001) Karunasekera, K.A.W.; Perera, K.P.J.INTRODUCTION : Prevalence of asthma and atopy among school children in Sri Lanka is not known. Objectives : To estimate prevalence of asthma and atopy in children between 5-11 years and to determine the influence of sex and age on the prevalence of asthma. METHODS: A total of 2043 children between 5-11 years of 3 mixed schools in Gampaha district were screened for symptoms of asthma and atopy using a questionnaire in August 1998. Diagnosis of asthma was based on the presence of 3 symptoms of the following 5 in the preceding 12 months; cough at night, breathlessness, wheezing, persistent cough more than a week after common cold and cough and/or chest tightness during or after playing. Chi squared test and Chi squared test for trend were used for analysis. RESULTS: Prevalence of asthma symptoms were cough at night 22.1%, breathiessness 17.2%, wheezing 22.6%, persistent cough after common cold 29.9% and cough or chest tightness with playing 11%. Prevalence of asthma based on questionnaire was 17.1 %, allergic rhinitis 10% and eczema 2.5%. The prevalence of asthma in males was not significantly different from that of females (p=0.4). There was a decreasing trend of the prevalence of asthma with increasing age. This trend was significant in girls (p= 0.01) but not in boys. CONCLUSIONS: Nearly one fifth of primary school children suffer from asthma and 10% have allergic rhinitis. There was no significant gender difference in Jhe prevalence of asthma in primary school children. There was a decreasing trend of the prevalence of asthma with increasing age in girls but not in boys.
