Increase of blood culture contamination during COVID-19 pandemic. A retrospective descriptive study.

ABSTRACT:

Background

Secondary bacterial infection during the care of coronavirus disease 2019 (COVID-19) patients poses risks to the patients, but there are concerns of an increase in blood culture contamination.

Methods

A retrospective comparative study was conducted from April 1 to December 31, 2020, when the patients with COVID-19 were taken care of (pandemic period, PP), and it was compared with the same period in 2019 (pre-pandemic period, pre-PP).

Results

A total of 346 patients with COVID-19 were hospitalized during the study period in 2020. A total of 1,040 and 918 blood cultures were taken during PPP and PP respectively. 38 and 56 contaminations occurred during pre-PP and PP respectively (3.7% [95% CI 2.6%-5.0%], vs 6.1% [95% CI 4.6%-7.8%], P = .015). For the ICU, 10 and 32 contaminations occurred during the same periods (5.0% [95% CI 2.4%-9.0%], vs 12.5% [95% CI 8.7%-17.1%], P = .0097). True bacteremia in the ICU per patient-day also increased during the PP.

Conclusions

We found a significant increase in blood culture contamination during the COVID-19 pandemic in the ICU setting, while true bacteremia also increased. A safe and effective way to obtain blood cultures from patients with COVID-19 should be sought.

Project description:Covid-19 pandemic had affected transfusion services including recruitment of donors and blood donation camps activities. The blood donors may have concerns, confusion, and misleading rumours about blood donation during pandemic. People's priorities for blood donation may shift because of a dearth of necessities. It is important to identify factors which prevent or motivate blood donors during pandemic. This study was designed to understand blood donors' knowledge, attitudes, and perceptions during the Covid-19 pandemic. A descriptive cross-sectional study to assess donor's knowledge, attitude, and perception regarding blood donation using self-administered 20 questions. The study duration was 4 months. A total 503 whole blood donors participated. The fear of infection and reduced blood donor motivation were observed to be the major deterrents of blood donation activity. Environment of blood donation area and travel to blood donation site were perceived two major sources of Covid-19 infection by participants. The top 3 motivational factor for blood donation were direct patient request to donate (30%), followed by family/ friends need and social media campaigns (26% each). Most donors (70.6%) were aware of importance of Covid-19 appropriate behaviour during current pandemic. The 67% donors felt that adequate Covid-19 preventive measures had been followed by the staff involved in blood collection. Based on the survey results, the inferences are that donors may harbour fear of infection and concerns for their safety, deterring blood donation. The direct appeal from a patient's relative to donate blood or a requirement in their family/friends and social media appeals emerge important factors to motivate donors. Travel facility arrangement may aide blood donation. Most of the donors are more than satisfied with the blood donation experience and are motivated to inform the transfusion services of any appearance of Covid-19 symptoms post donation. The donors were satisfied with the steps to reduce Covid-19 infection.Supplementary informationThe online version contains supplementary material available at 10.1007/s12288-021-01504-y.
