Effectiveness of COVID-19 pre-operative protocol to prevent in-hospital transmission among healthcare personnel and patients undergoing elective cataract surgery under local anesthesia

Completed

• Conditions: The patients had severe visual impairment due to cataractHealth care personnel; Cataract surgery, COVID-19, Pre-operative SARS-CoV-2 screening, pool PCR testing

• Registration Number: TCTR20210603002
• Lead Sponsor: Faculty of Medicine, Mahasarakham University, Mahasarakham, Thailand

Brief Summary

Healthcare personnel tested negative in each of the four consecutive weekly rRT-PCR nasopharyngeal-throat swabs for SARS-CoV-2. Their two SARS-CoV-2 IgG tests were also negative. The estimated incidence rate of COVID-19 infection among healthcare personnel was 0 (95% CI, 0.000-0.003) per 100 person-hours. Therefore, there were no differences in infection rates between patients screened by nasopharyngeal-throat swabs plus questionnaire and those screened by questionnaire only.
