Justifying quarantine in preventing the spread of COVID-19 in healthcare

Background

The first COVID-19-positive patient was identified in Ireland on 29 February 2020 (Department of Health, Government of Ireland; https://www.gov.ie/en/pressrelease/2f75fd-statement-from-the-national-public-healthemergency-team-sat-29-feb/). Healthcare worker (HCW) quarantining became a core intervention for those identified as ‘close contacts’ to reduce onward transmission within the workplace to patients and colleagues. Whether a quarantining strategy could be justified at a time when there was an increased demand for the services of HCWs remained unknown.

Aims

To establish whether quarantining staff away from a healthcare setting during a pandemic is justified.

Methods

This retrospective study examined close contacts of COVID-19-positive index cases (both residents and HCWs) in a community hospital over a 4-week period from 1 to 28 April 2020. Close contacts were identified in accordance with national guidelines. Zones of the hospital were examined to determine the number of COVID-positive index cases and their close contacts. A cumulative result for the hospital was recorded.

Results

While outcomes varied over time, per zone and per HCW category, the overall conversion rate from close contact to an index case was 30%.

Conclusions

This study vindicates the policy of quarantining close contact HCWs from their workplaces as they pose a significant threat to both their patients and fellow workers.

Irish Defence Forces combat medical technician training: experience of a novel university medical school-based programme

AIMS

This study explores the opinions and experiences of Irish Defences Forces' (IDF) graduates from University College Dublin's Diploma in Military Medicine Care (DMMC). It aims to identify which aspects of medical education are relevant for the development of military graduates in the role of Combat Medical Technician (CMT) in future.

METHODS

A validated Clinical Learning Environment Score tool was adapted and incorporated into an online survey. This was sent electronically to 71 graduates. Responses were anonymous.

RESULTS

38 (54%) graduates responded. Student feedback was positive regarding teaching and clinical placements in the DMMC. In total 16 (42%) students reported use of their new skills in their daily work. Of the 9 (24%) deployed overseas, all used their new skills. Emergency and occupational health skills were used more frequently, while advanced skills were used rarely.

CONCLUSION

An increased emphasis on frequently used skills should be considered. Links to healthcare services would be of benefit to graduates in skills maintenance. Key advanced skills, such as intravenous cannulation and advanced airway management are rarely used but mechanisms to maintain them will improve the relevance of the programme to the CMT role. A change in how the IDF acknowledges qualifications may support more graduates in advancing and maintaining their career in the military medical workforce.

Should adjuvant chemotherapy be withheld from any patient with operable breast cancer?

We examined the clinical course of operable breast cancer and looked at what effect tumour size had on the probability of death from the disease. We analysed data from 1936 patients who were classified as having international stage I and II disease: decision theory was used to show a technique for determining the best strategy for adjuvant chemotherapy in the overall management of breast cancer.To evaluate this approach further, studies need to be designed to yield numerical values for the total morbidity of treatment on a scale from 0 to 100-the concept of utility loss-where 100 represents the maximum utility loss in patients in the early stages of disease. Such studies would contribute more to determining the best overall management of such patients than the current proliferation of clinical trials that are designed to evaluate either different combinations of adjuvant drugs or the effect of known combinations in selected subgroups of patients.
