    Evaluating the programme and behavior change theories of a community alcohol education intervention in rural Sri Lanka: a study protocol

    by Jane Brandt Sørensen, K. S. Kylie Lee, Angela Dawson, Lalith Senarathna, P. H. G. Janaka Pushpakumara, Thilini Rajapakse, Flemming Konradsen, Nick Glozier, Katherine M. Conigrave, Prabash Siriwardhana, et al.

    Risky alcohol use is a major public health problem globally and in Sri Lanka. While a reduction in alcohol consumption can result in physical, mental, and social benefits, behaviour change is difficult to achieve. Effective, context-adapted interventions are required to minimise alcohol-related harm at a community level. THEATRE is a complex, community-based intervention evaluating whether a promising Sri Lankan pilot study that utilised arts-based research to moderate alcohol use can be scaled up. While the scaled-up pilot study protocol is presented elsewhere, the aim of this protocol paper is to describe the intervention programme theory and evaluation design, and modifications made to the study resulting from COVID-19 and the financial crisis. Drawing on the Behaviour Change Wheel (BCW) and Theoretical Domains Framework, behaviour change theories are presented with potential pathways to guide implementation and evaluation. Alcohol consumption patterns and context of drinking is detailed. The multifaceted intervention targets individuals and communities using arts-based interventions. Four of nine BCW functions are employed in the design of the intervention: education, persuasion, modelling and enablement, and training. Modifications made to the study due to COVID-19 and the financial crisis are described. Ethical approval was obtained from the Ethics Review Committee, Faculty of Medicine and Allied Sciences, Rajarata University of Sri Lanka (ERC/2018/21-July 2018 and Feb 2022) and the University of Sydney (2019/006). Findings will be disseminated locally to community members and key stakeholders and via international peer-reviewed publications.

    Clinical and psychosocial factors associated with domestic violence among men and women in Kandy, Sri Lanka

    by Piumee Bandara, Andrew Page, Lalith Senarathna, Kumudu Wijewardene, Tharuka Silva, David Gunnell, Duleeka Knipe, Thilini Rajapakse

    Domestic violence (DV) is a violation of human rights with adverse intergenerational consequences on physical and mental health. Clinical and psychosocial correlates of DV have been documented internationally, but evidence from South Asia is limited, especially among men. This is a nested cross-sectional study of the control population (N = 856) of a large case-control study in Kandy, Sri Lanka. Multivariable logistic regression models were conducted to estimate the association between clinical and psychosocial factors and experience of DV. Overall associations were examined and stratified by sex and type of abuse. Overall, 19% (95% CI 16%-21%) of the sample reported DV of any form in past year, with a similar prevalence being reported in both men (18% 95% CI 14%–22%) and women (19% 95% CI 15%–23%). Depression symptoms (adjusted OR [AOR] 3.28 95% CI 2.13–5.05), suicidal ideation (AOR 6.19 95% CI 3.67–10.45), prior diagnosis of a mental illness (AOR 3.62 95% CI 1.61–8.14), and previous self-harm (AOR 6.99 95% CI 3.65–13.38) were strongly associated with DV, as were indicators of perceived poor social support (AOR range 2.48–14.18). The presence of in-laws (AOR 2.16 95% CI 1.34–3.48), having three or more children (AOR 2.15 95% CI 1.05–4.41) and being divorced/separated/widowed were also strongly associated with DV (AOR 2.89 95% CI 1.14–7.36). There was no statistical evidence that any associations differed by sex. A multi-sectoral approach is needed to address DV in this context. Enhanced coordination between DV support services and mental health services may be beneficial. Further research and support for men as well as women is needed.

    Sex education and self-poisoning in Sri Lanka: an explorative analysis

    by Grace Crowley, Piumee Bandara, Lalith Senarathna, Ayodhya Malalagama, Sonali Gunasekera, Thilini Rajapakse, Duleeka Knipe

    Background: Self-harm and suicide are important causes of morbidity and mortality in Sri Lanka, but our understanding of these behaviours is limited. Qualitative studies have implicated familial and societal expectations around sex and relationships. We conducted an explorative analysis using case-control data to investigate the association between sex education and self-poisoning in Sri Lanka.Methods: Cases (N=298) were self-poisoning inpatients on a toxicology ward, Teaching Hospital Peradeniya. Controls (N=500) were sex and age frequency matched to cases and were outpatients/visitors to the same hospital. Participants were asked whether they had received sex education, and to rate the quality and usefulness of any sex education received. Logistic regression models adjusted for age, sex, and religion quantified the association between receipt, quality and usefulness of sex education and self-poisoning. We tested whether the associations differed by sex.Results: Roughly 1-in-3 cases and 1-in-5 controls reported having not received sex education. Individuals who did not receive sex education were nearly twice as likely to have self-poisoned than those who did (OR 1.68 (95% CI 1.11-2.55)). Those who reported the sex education they received as not useful were more likely to have self-poisoned compared to those who reported it useful (OR 1.95 (95% CI 1.04-3.65)). We found no evidence of an association between self-poisoning and the self-rated quality of sex education, or that associations differed by participant sex.Conclusion: As sex education is potentially modifiable at the population-level, further research should aim to explore this association in more depth, using qualitative methods and validated measurement tools.

    Paediatric poisoning in rural Sri Lanka: an epidemiological study

    by Godakanda Arachchige Maneesha Prasadi, Fahim Mohamed, Lalith Senarathna, Rose Cairns, Pahala Hangidi Gedara Janaka Pushpakumara, Andrew Hamilton Dawson

    Acute paediatric poisoning is a common public health concern for both developed and developing countries. The type of agent and underlying cause differ depending on the social, cultural, economic and educational background. The objectives of this study were to identify the incidence and pattern of paediatric poisoning in a rural district in Sri Lanka and establish whether tertiary referral hospital data are a useful surrogate for estimating district level epidemiology of paediatric poisoning. A subset of epidemiological data were obtained from March 2011 to February 2013 from a randomized controlled trial (SLCTR/2010/008) conducted in 45 hospitals in Kurunegala district. The age adjusted annual incidence of all cause of acute poisoning in children aged 1 to 12 years in the study area was 60.4 per 100,000. The incidence of poisoning of younger age group (1 to 6 years; 76 per 100,000) was significantly higher than older age group (7 to 12 years; 41 per 100,000) (p = 0.0001) in Kurunegala district. The annual incidence rate of paediatric admissions due to deliberate self-poisoning is 18 per 100,000 population. This study also established that admission data from primary hospitals provided the most accurate epidemiological information on paediatric poisoning. In rural districts of Sri Lanka, acute paediatric poisoning cases were less frequent and less severe compared to adult poisoning cases (426–446 per 100,000 population). The incidence of poisoning was significantly higher among young children with compared to old children. In this study, deliberate self-poisoning among older children was more frequently seen than in other comparable countries. Because most of the admissions are directed to and managed by primary hospitals, data from referral hospitals alone cannot be used to represent the true incidence of acute poisoning within a district. The data set from all the primary hospitals (n = 44) yielded more accurate poisoning incidence amongst a paediatric population.

    The effect of a community based health promotion intervention to change gender norms among women in a rural community in Sri Lanka

    by T. Herath, D. Guruge, M. Fernando, S. Jayarathna, L. Senarathna

    Gender norms practiced by respective societies increase the risk of violence by men against women. To date, there is a dearth of research evidence on changing gender norms through health promotion approaches around the globe, including in Sri Lanka. This study provides an evaluation of effectiveness of a health promotion intervention in changing the acceptance of gender norms among women. A quasi-experimental study was conducted in two rural villages in Anuradhapura district in Sri Lanka including women who have a child under five years of age. One village was allocated to receive an intervention developed based on a health promotion approach and the other village was a control. A community based mechanism to question selected gender norms among women was developed as the intervention. The pre- and post-intervention assessments of the level of acceptance of gender norms were done using an interviewer administered questionnaire and by using focus group discussions. Following the intervention, acceptances of prominent gender norms were changed significantly among the women receiving the intervention method. The control group showed no changes towards the acceptance of gender norms during this period. Women in the intervention group had higher levels of self-reported positive behavior changes and greater understanding of gender concepts compared to the control group. The acceptance of gender norms among women in rural villages in Sri Lanka can be changed by a community based intervention targeting gender norms.


  • Social Dynamics in Rural Sri Lankan Hospitals

    by Lalith Senarathna, Cynthia Hunter, Andrew H. Dawson, Michael J. Dibley

    Different hospitals produce different cultures—products of relationships between people of different staff categories and people from external community groups. These relationships demonstrate unique social dynamics in rural peripheral hospitals that form a major part of the health care system in Sri Lanka and other developing countries. Understanding the existing social dynamics might be useful when trying to implement new treatment guidelines that can involve behavior change. We aimed to explore the existing social dynamics in peripheral hospitals in rural Sri Lanka by examining the treatment related to cases of acute self-poisoning that is a common, highly interactive medical emergency. These hospitals demonstrate higher levels of community influence in treatment decisions and closer interactions between hospital staff. We argue that health care teamwork is effective in peripheral hospitals, resulting in benefits to all staff, who see these hospitals as better places to work and train, in contrast to a commonly held belief that such rural hospitals are disadvantaged and difficult places.

    Effect of a Brief Outreach Educational Intervention on the Translation of Acute Poisoning Treatment Guidelines to Practice in Rural Sri Lankan Hospitals: A Cluster Randomized Controlled Trial

    by Lalith Senarathna, Nick A. Buckley, Michael J. Dibley, Patrick J. Kelly, Shaluka F. Jayamanna, Indika B. Gawarammana, Andrew H. Dawson

    In developing countries, including Sri Lanka, a high proportion of acute poisoning and other medical emergencies are initially treated in rural peripheral hospitals. Patients are then usually transferred to referral hospitals for further treatment. Guidelines are often used to promote better patient care in these emergencies. We conducted a cluster randomized controlled trial (ISRCTN73983810) which aimed to assess the effect of a brief educational outreach (‘academic detailing’) intervention to promote the utilization of treatment guidelines for acute poisoning. This cluster RCT was conducted in the North Central Province of Sri Lanka. All peripheral hospitals in the province were randomized to either intervention or control. All hospitals received a copy of the guidelines. The intervention hospitals received a brief out-reach academic detailing workshop which explained poisoning treatment guidelines and guideline promotional items designed to be used in daily care. Data were collected on all patients admitted due to poisoning for 12 months post-intervention in all study hospitals. Information collected included type of poison exposure, initial investigations, treatments and hospital outcome. Patients transferred from peripheral hospitals to referral hospitals had their clinical outcomes recorded. There were 23 intervention and 23 control hospitals. There were no significant differences in the patient characteristics, such as age, gender and the poisons ingested. The intervention hospitals showed a significant improvement in administration of activated charcoal [OR 2.95 (95% CI 1.28–6.80)]. There was no difference between hospitals in use of other decontamination methods. This study shows that an educational intervention consisting of brief out-reach academic detailing was effective in changing treatment behavior in rural Sri Lankan hospitals. The intervention was only effective for treatments with direct clinician involvement, such as administering activated charcoal. It was not successful for treatments usually administered by non-professional staff such as forced emesis for poisoning. Controlled-Trials.com ISRCTN73983810 ISRCTN73983810

    Changing epidemiologic patterns of deliberate self poisoning in a rural district of Sri Lanka

    by Lalith Senarathna, Shaluka F Jayamanna, Patrick J Kelly, Nick A Buckley, Michael J Dibley, Andrew H Dawson

    Acute poisoning is a major public health issue in many parts of the world. The epidemiology and the mortality rate is higher in low and middle income countries, including Sri Lanka. The aim of this study was to provide details about the epidemiology of acute poisoning in a rural Sri Lankan district and to identify the changing patterns and epidemiology of poisoning.


  • Validity of referral hospitals for the toxicovigilance of acute poisoning in Sri Lanka

    by L Senarathna, NA Buckley, Sf Jayamanna, Pj Kelly, Mj Dibley, Ah Dawson

    To identify the hospital admission data set that best captures the incidence of acute poisoning in rural Sri Lanka. Data were collected on all acute poisoning cases admitted to 34 primary and 1 referral hospital in Anuradhapura district from September 2008 to January 2010. Three admission data sets were compared with the "true" incidence of acute poisoning to determine the systematic bias inherent to each data set. "True" incidence was calculated by adding all direct admissions (not transfers) to primary hospitals and to the referral hospital. The three data sets were: (i) all admissions to primary hospitals only; (ii) all admissions to the referral hospital only (direct and referrals), and (iii) all admissions to both primary hospitals and the referral hospital ("all admissions"). The third is the government's routine statistical method but counts transfers twice, so for the study transferred patients were counted only once through data linkage. Of 3813 patients admitted for poisoning, 3111 first presented to a primary hospital and 2287 (73.5%) were later transferred to the referral hospital, where most deaths (161/177) occurred. All data sets were representative demographically and in poisoning type, but referral hospital data yielded a more accurate case-fatality rate than primary hospital data or "all admissions" data. Admissions to primary hospitals only or to the referral hospital only underestimated the incidence of acute poisoning by about 20%, and data on "all admissions" overestimated it by 60%. Admission data from referral hospitals are easily obtainable and accurately reflect the true poisoning incidence.
