Background Global recognition of antimicrobial resistance (AMR) as an urgent public health problem has galvanized national and international efforts. Chief among these are interventions to curb the overuse and misuse of antibiotics. However, the impact of these initiatives is not fully understood, making it difficult to assess the expected effectiveness and sustainability of further policy interventions. We conducted a systematic review to summarize existing evidence for the impact of nationally enforced interventions to reduce inappropriate antibiotic use in humans. Methods We searched seven databases and examined reference lists of retrieved articles. To be included, articles had to evaluate the impact of national responsible use initiatives. We excluded studies that only described policy implementations. Results We identified 34 articles detailing interventions in 21 high- and upper-middle-income countries. Interventions addressing inappropriate antibiotic access included antibiotic committees, clinical guidelines and prescribing restrictions. There was consistent evidence that these were effective at reducing antibiotic consumption and prescription. Interventions targeting inappropriate antibiotic demand consisted of education campaigns for healthcare professionals and the general public. Evidence for this was mixed, with several studies showing no impact on overall antibiotic consumption. Conclusions National-level interventions to reduce inappropriate access to antibiotics can be effective. However, evidence is limited to high- and upper-middle-income countries, and more evidence is needed on the long-term sustained impact of interventions. There should also be a simultaneous push towards standardized outcome measures to enable comparisons of interventions in different settings.

ObjectivesThe WHO’s Global Action Plan on Antimicrobial Resistance (AMR) includes increasing overall public awareness of appropriate antibiotic use and resistance as a key priority area. We aimed to measure public knowledge, attitudes and practices of antibiotics and antibiotic resistance in Singapore, as well as their healthcare-seeking behaviours relating to respiratory illnesses, providing baseline data against which to measure the progress of future interventions.DesignA cross-sectional study.SettingThe general population in Singapore.ParticipantsBetween May and June 2019, we conducted a survey via an online panel in Singapore with 706 respondents.ResultsOur findings indicated common misconceptions surrounding antibiotic effectiveness and mechanisms of antibiotic resistance—most participants thought that resistance occurs when our bodies become resistant to antibiotics (62.5%) or when antibiotics become less powerful (48.5%). In multivariable analyses, better knowledge scores were associated with more favourable antibiotic attitudes (β=0.29; 95% CI 0.20 to 0.37). In addition, more favourable attitude scores were associated with lower odds of both expecting (OR: 0.84, 95% CI 0.72 to 0.99) and being prescribed antibiotics by a primary care doctor (OR: 0.76, 95% CI 0.63 to 0.90).ConclusionsThis study presents important information about population perceptions towards antibiotics and antibiotic resistance in Singapore. Results from this study emphasise the importance of effective public communication strategies to promote responsible antibiotic use locally and should be used to inform future implementation of programmes and activities as laid out in Singapore’s National Strategic Action Plan on AMR.

Vitamin B-12 deficiency was associated with risk of grade repetition and school absenteeism rates in school children from Bogota, Colombia. The effects of correcting vitamin B-12 deficiency on educational outcomes and neurocognitive development of school children need to be determined in intervention studies.

This pilot study aimed to explore the benefits of an online Symptom Care and Management System (SCMS) in the home monitoring and symptom management of patients receiving chemotherapy. A single-group experimental design was employed, and four patients aged 39-59 years undergoing their first chemotherapy treatment were recruited from one cancer centre in Singapore from November 2010 to February 2011. A mixed method was used to collect patient's data. All patients used the SCMS to record and send daily symptom reports to the cancer centre and receive symptom management advice from the nurse via teleconferencing. Patients' perceptions on the use of the system were evaluated. All participants believed that the system improved the management of their symptom and felt reassured they were being monitored at home. The results presented in this pilot study suggest that the SCMS has the potential to enhance the remote monitoring, feasible and acceptable way for a specific group of cancer patients to manage their symptom at home.
