Impact of COVID-19 on quality checks of solid tumor molecular diagnostic testing-A surveillance by EQAS provider in India.

BACKGROUND: Molecular tests in solid tumours for targeted therapies call for the need to ensure precision testing. To accomplish this participation in the External Quality Assessment Program (EQAS) is required. This evaluates the consistency of diagnostic testing procedures and offers guidance for improving quality. Outbreak of COVID-19 pandemic led to worldwide lockdown and disruption of healthcare services including participation in EQAS.The present study describes the extended scope of EQAS offered byMPQAP (Molecular Pathology Quality Assurance Program), the first proficiency test provider for solid tumor diagnostics in India. The study surveys the preparedness of molecular testing laboratories in routine diagnostics and participation for quality assessment scheme. METHODS: A documented guideline for measures and precautions to be carried by testing laboratories in performing routine diagnostic tests during the lockdown period were charted and distributed to all MPQAP participant centres. A survey was conducted for MPQAP participants to check whether laboratories were involved in COVID-19 testing and to evaluate the impact of lockdown on the operations of diagnostics procedures. From the acquired response of the survey, 2 cycles out of initially proposed 11 cycles were executed with transformed approach using digital tools and image interpretation modules. FINDINGS: Out of 25 solid tumour testing laboratories registered as participants, 15 consented to participate in survey. The summary of survey conveyed the impact of COVID-19onroutine operations of diagnostics tests such as shortcomings in inventory and human resource management. Thirteen participants showed active willingness and consented to participate in EQAS test scheme. INTERPRETATIONS: The survey findings and assessment of EQAS cycles endorsed the quality testing procedures carried by participating laboratories throughout the lockdown. It highlighted the utility of EQAS participation during pandemic along with emphasis on safety measures for continual improvement in quality of diagnostic services.

Outcomes of COVID-19 and risk factors in patients with cancer.

Patients with cancer are at higher risk for adverse coronavirus disease 2019 (COVID-19) outcomes. Here, we studied 1,253 patients with cancer, who were diagnosed with severe acute respiratory syndrome coronavirus 2 at a tertiary referral cancer center in India. Most patients had mild disease; in our settings, recent cancer therapies did not impact COVID-19 outcomes. Advancing age, smoking history, concurrent comorbidities and palliative intent of treatment were independently associated with severe COVID-19 or death. Thus, our study provides useful insights into cancer management during the COVID-19 pandemic.

Incidence of SARS-CoV-2 infection among asymptomatic patients undergoing preoperative COVID testing prior to cancer surgery: ASPECT study.

BACKGROUND AND OBJECTIVES: The COVID-19 pandemic, with high rate of asymptomatic infections and increased perioperative complications, prompted widespread adoption of screening methods. We analyzed the incidence of asymptomatic infection and perioperative outcomes in patients undergoing cancer surgery. We also studied the impact on subsequent cancer treatment in those with COVID-19. METHODS: All patients who underwent elective and emergency cancer surgery from April to September 2020 were included. After screening for symptoms, a preoperative test was performed from nasopharyngeal and oropharyngeal swabs before the procedure. Patients were followed up for 30 days postoperatively and complications were noted. RESULTS: 2108 asymptomatic patients were tested, of which 200 (9.5%) tested positive. Of those who tested positive, 140 (70%) underwent the planned surgery at a median of 30 days from testing positive, and 20 (14.3%) had ≥ Grade III complications. Forty (20%) patients did not receive the intended treatment; 110 patients were retested in the Postoperative period, and 41 (37.3%) tested positive and 9(22%) patients died of COVID-related complications. CONCLUSION: Routine preoperative testing for COVID-19 helps to segregate patients with asymptomatic infection. Higher complications occur in those who develop COVID-19 in postoperative period. Prolonged delay in surgery after COVID infection may influence planned treatment.

COVID 19 pandemic testing time - Crisis or opportunity in disguise for India?

The current SARS-CoV-2 infection or the COVID 19 pandemic has taken the world by storm, where the best health care systems in the world seem to be overwhelmed and still this virus is eluding us as we are compelled to explore the preventive and/or therapeutic interventions to control the disease outbreak as well as to prevent deaths. In parallel to clinical services, laboratories have been overwhelmed with task of keeping up with ever increasing demand for testing. Real time PCR detection of COVID19 is the gold standard method, however, has certain shortcomings in terms of availability of infrastructure, reagents, consumables, and technical expertise. All these have paved the way for the alternative testing algorithms and strategies. Countries like United States and Italy have struggled with these issues. India has been criticized for not testing enough and not adopting the right policy, but has been managing the disease within its resource limited health care system to a fair extent. The present review provides the Indian perspective of COVID 19 testing, the journey from not testing enough in the past to a vast expanse and depth of testing in present time.
