RESUMEN
BackgroundThe role of schools in SARS-CoV-2 transmission has been a debated topic since the beginning of the COVID-19 pandemic.AimTo examine SARS-CoV-2 transmission in all schools in Ireland during the 2020-21 school year.MethodsIn a national descriptive cross-sectional study, we investigated PCR-confirmed cases of COVID-19 among students (aged < 20 years) and staff (aged ≥ 20 years) who attended school during their infectious period to identify school close contacts. SARS-CoV-2 PCR test results of all school close contacts were pooled to obtain an overall positivity rate and to stratify positivity rate by school setting and role (i.e. student or staff).ResultsIn total, 100,474 individuals were tested as close contacts in 1,771 schools during the 2020-21 school year. An overall close contact positivity rate of 2.4% was observed across all schools (n = 2,373 secondary cases). The highest positivity rate was seen in special schools (3.4%), followed by primary (2.5%) and post-primary schools (1.8%) (p < 0.001). Of the close contacts identified, 90.5% (n = 90,953) were students and 9.5% (n = 9,521) were staff. Overall, students had a significantly higher positivity rate than staff (2.4% vs 1.8%, p < 0.001).ConclusionThis study demonstrated that a low level of SARS-CoV-2 transmission occurred in Irish schools during the 2020-21 academic year. In the event of future pandemics, and as the COVID-19 pandemic continues, there is a need to carefully weigh up the harms and benefits associated with disrupted education to mitigate infectious disease transmission before reflexively closing classes or schools.

AIMS: To assess levels and correlates of adherence to hypoglycaemic medication among patients offered organised general practice diabetes care. METHODS: 60 patients prescribed oral hypoglycaemic medication were recruited to a two-month prospective study. Prescribed doses taken and days on which the prescribed number of doses was taken were measured by MEMS (Medication Event Monitoring System). RESULTS: Overall 99.1% of prescribed doses were taken (median, IQR: 96.8-100%), this was inversely correlated with daily dose frequency (Spearman's rho=0.37, p=0.004). Only 4 patients (6.7%) took less than 90% of prescribed doses. The prescribed dose was taken on 96.4% of days (median, IQR: 89.1-98.2%), this was correlated with age (rho=0.26, p=0.047) and inversely correlated with HbA(1c) levels (rho=-0.29, p=0.02) and daily dose frequency (rho=-0.33, p=0.009). Adherence to metformin was less than to other hypoglycaemic medication (Z=-3.48, p=0.0005). CONCLUSIONS: A dispensing practice with a well-run diabetes service can support high rates of adherence to hypoglycaemic medication. Before changing medication, low adherence might be considered as a possible cause of progressive hyperglycaemia, particularly among patients prescribed metformin more than once a day. Selective monitoring with MEMS may have a clinical as well as a research role in such people.
