Compliance with local travel restrictions and face masks during first phase of COVID-19 pandemic in Ireland: a national survey

Background

This study examines compliance with local travel restrictions and assesses early uptake of mask wearing, during the initial phase of the coronavirus disease of 2019 (COVID-19) pandemic in Ireland, to inform the ongoing outbreak response.

Methods

A series of four nationally representative telephone surveys were developed. Information was collected at a household level and from primary respondents. Multivariable logistic regression estimated the association between sociodemographic characteristics and compliance with the local travel restriction and with mask use in primary respondents.

Results

Household compliance with local travel restrictions was similar by region, household size and social position. 73.4% of all household members complied, with high levels maintained over time. Higher proportions reported travelling for non-permitted reasons with time. Older age, female gender and attending higher education were independently associated with compliance to local travel restrictions. Among primary respondents, no factors were independently associated with mask use.

Conclusion

High compliance with local travel restrictions during the early stages of the pandemic demonstrates the engagement of the population with public health guidance. Although high compliance with local travel restrictions was generally maintained over time, non-permitted activities increased. Early adoption of mask use before required by national policy or legislation provides further evidence of the responsiveness of the population.

Cohort profile update: The Cork and Kerry Diabetes and Heart Disease Study

Background: The Cork and Kerry Diabetes and Heart Disease Study was established to investigate the prevalence of diabetes and cardiovascular disease among middle-aged adults in Ireland. The Mitchelstown cohort was recruited from a single large primary care centre between 2010-2011. A rescreen of this cohort was conducted in 2015. Methods: Data were collected on cardiovascular health and associated risk factors. In addition, the rescreen incorporated new measures which included information on cognition and frailty, medication adherence, dietary factors and the collection of stool samples with RNA sequencing of the gut microbiome. Results: Of 2047 participants in the original cohort, 237 (11.6%) were deceased, too ill to participate or were lost to follow-up. Of the remaining 1810 baseline study participants, 1378 men and women aged 51-77 years agreed to take part in the rescreen (response rate of 76.1%). The prevalence of hypertension was high, ranging from 50% to 64% depending on the measurement method. An investigation of the association of gut microbiota with metabolic syndrome and obesity indicated greater microbiome diversity in metabolically healthy non-obese individuals relative to their unhealthy counterparts. Analysis of prescribing data over time demonstrated a high prevalence of potentially inappropriate prescribing among older-aged people in primary care which increased as they progressed to more advanced old age. Conclusions: The rescreen has provided new insights into cardiovascular health. In addition, this study is embedded in a single primary care centre, enabling passive follow-up of study participants through electronic health records. All data collected at baseline and rescreen are maintained and stored at the School of Public Health, University College Cork and specific proposals for future collaborations are welcome.

COVID-19 pandemic in Ireland: Epidemiology, public health restrictions and vaccination uptake

Background: The first wave of COVID-19 pandemic in Ireland was managed by a prolonged national lockdown. The second and third waves were managed by continued non-pharmaceutical interventions (NPIs) and deployment of a national vaccination programme. This paper aims to describe the epidemiological trends, Public Health restrictions and vaccination uptake during the first three waves of the pandemic.   Methods: Data on confirmed cases of COVID-19 from 1 March 2020 to 27 March 2021 were extracted from the national COVID-19 data hub, the Health Protection Surveillance Centre (HPSC) and the National Contact Management Programme. Vaccine uptake and epidemiological data from European Centre for Disease Prevention and Control were reported from four other EU states.  Results: Ireland experienced three distinct waves of COVID-19; first wave occurred March to August 2020, second August to November 2020 and third from November 2020 onwards. The third wave was attributable to emergence of the Alpha variant of concern (B.1.1.7 strain) and relaxation of public health restrictions in December 2020, when weekly mean number of close contacts per case peaked at 5.2. A similar epidemiological trajectory was observed across four other EU states.   Conclusions: Surges of COVID-19 continue to occur despite increasing vaccine coverage in the EU, due to the emergence of novel variants of concern and relaxation of Public Health restrictions. A “vaccine plus policy” is needed.

Cross-sectional survey of compliance behaviour, knowledge and attitudes among cases and close contacts during COVID-19 pandemic

Objectives

A key public health intervention is self-isolation for cases and restriction of movement for contacts. This study aimed to identify predictors of compliance behaviour and describe knowledge and attitudes among cases and contacts identified by the national Contact Management Programme to inform the global public health response.

Study design

Secondary data analysis of anonymised cross-sectional survey data on national sample of cases and close contacts.

Methods

A sample of 1000 cases and 1000 contacts was calculated to estimate compliance within a margin of error of 3% with 95% confidence. A telephone survey administered by trained interviewers collected information on socio-demographics, compliance behaviours, knowledge, and attitudes to COVID-19 from cases and close contacts. Data analysis included chi-squared statistics and multivariable logistic regression.

Results

Most cases and contacts complied with public health guidance with similar characteristics in those who did and did not comply. Reasons for non-compliance included exercise, medical appointment, shopping, and work. Cases and contacts reported high levels of understanding about symptoms of COVID-19 and satisfaction with available information.

Conclusion

Achieving high compliance with public health guidance is feasible and requires political leadership, policy changes and practical solutions.

Health care utilization and the associated costs attributable to cardiovascular disease in Ireland: a cross-sectional study

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of mortality and disability globally. We examined healthcare service utilization and costs attributable to CVD in Ireland in the period before the introduction of a major healthcare reform in 2016.

METHODS

Secondary analysis of data from 8113 participants of the first wave of The Irish Longitudinal Study on Ageing. Cardiovascular disease was defined as having a self-reported doctor's diagnosis of myocardial infarction, angina, heart failure, stroke, atrial fibrillation, or transient ischaemic attack. Participants self-reported the utilization of healthcare services in the year preceding the interview. Negative binomial regression with average marginal effects (AMEs) was used to estimate the incremental number of general practitioner (GP) and outpatient department (OPD) visits, accident and emergency department attendances and hospitalizations in population with CVD relative to population without CVD. We calculated the corresponding costs at individual and population levels, by gender and age groups.

RESULTS

The prevalence of CVD was 18.2% (95% CI: 17.3, 19.0) Participants with CVD reported higher utilization of all healthcare services. In adjusted models, having CVD was associated with incremental 1.19 [95% confidence interval (CI): 0.99, 1.39] GP and 0.79 (95% CI: 0.65, 0.93) OPD visits. There were twice as many incremental hospitalizations in males with CVD compared to females with CVD [AME (95% CI): 0.20 (0.16, 0.23) vs. 0.10 (0.07, 0.14)]. The incremental cost of healthcare service use in population with CVD was an estimated €352.2 million (95% CI: €272.8, €431.7), 93% of which was due to use of secondary care services.

CONCLUSION

We identified substantially increased use of healthcare services attributable to CVD in Ireland. Continued efforts aimed at CVD primary prevention and management are required.
