Evaluation of endoscopy requests in the resumption of activity during the SARS-CoV-2 pandemic: denial of nonindicated requests and prioritization of accepted requests.

Introduction: the global SARS-CoV-2 pandemic forced the closure of endoscopy units. Before resuming endoscopic activity, we designed a protocol to evaluate gastroscopies and colonoscopies cancelled during the pandemic, denying inappropriate requests and prioritizing appropriate ones.
Methods: two types of inappropriate request were established: a) COVID-19 context, people aged ≤ 50 years without alarm symptoms and a low probability of relevant endoscopic findings; and b) inappropriate context, requests not in line with clinical guidelines or protocols. Denials were filed in the medical record. Appropriate requests were classified into priority, conventional and follow-up. Requests denied by specialty were compared and the findings of priority requests were evaluated.
Results: between March 16th and June 30th 2020, 1,658 requests (44 % gastroscopies and 56 % colonoscopies) were evaluated, of which 1,164 (70 %) were considered as appropriate (priority 8.5 %, conventional 48 %, follow-up 43 % and non-evaluable 0.5 %) and 494 (30 %) as inappropriate (20 % COVID-19 context, 80 % inappropriate context). The reasons for denial of gastroscopy were follow-up of lesions (33 %), insufficiently studied symptoms (20 %) and relapsing symptoms after a previous gastroscopy (18 %). The reasons for denial of colonoscopies were post-polypectomy surveillance (25 %), colorectal cancer after surgery (21 %) and a family history of cancer (13 %). There were significant differences in denied requests according to specialty: General Surgery (52 %), Hematology (37 %) and Primary Care (29 %); 31 % of priority cases showed relevant findings.
Conclusions: according to our study, 24 % of endoscopies were discordant with scientific recommendations. Therefore, their denial and the prioritization of appropriate ones optimize the use of resources.
