RESUMO
Background: To study incidence of sinonasal mucormycosis in active and post COVID-19 patients in a district-level hospital in India and develop a simplified screening and referral protocol for use at peripheral centres to aid rapid diagnosis/treatment. Methods: Study design: A prospective, interventional cohort study conducted from April 2021 to January 2022. Setting: Secondary level hospital in North India. Inclusion criteria: COVID-19 positive patients with diabetes mellitus as co-morbidity and with at least one of the following: received steroid therapy and/or on high flow oxygen therapy and/or had prolonged hospital stay (> 7 days). Exclusion criteria: Patients already immunocompromised/having malignancy/organ transplant recipients. Clinical workup: History, examination, imaging (CECT/MRI nose and paranasal sinuses if indicated), diagnostic nasal endoscopy + Nasal scrapings for KOH mount to detect fungal elements. STROBE guidelines were followed in the study. Results: Fourteen out of 250 patients tested positive for mucormycosis (incidence 5.6%). Thirteen were symptomatic, one patient was asymptomatic and detected on screening. No significant difference was found in mucormycosis versus non-mucormycosis group with respect to HbA1c status, vaccination status or steroid + oxygen treatment (p > 0.05 in all scenarios). Patients were treated with intravenous liposomal amphotericin B and surgical debridement when indicated. Two succumbed to disease (survival 85.7%). A clinical screening protocol was thus developed which can be used as an effective tool even at far-flung and remote healthcare facilities for diagnosis and timely referral of patients. Conclusions: Mucormycosis is a potentially lethal disease which needs rapid diagnosis and timely action to decrease morbidity and mortality.
RESUMO
Background: Surgical site infections (SSIs) may be reduced by following SSI prevention measures. We assessed the SSI rate following caesarean section (CS) and gynaecologic surgery after implementing a simple SSI prevention bundle including preoperative bath and hair wash. Methods: The study was carried out in two hospitals in North India (Post Graduate Institute of Medical Education and Research [PGIMER] and Civil Hospital CH) from August 2018 to July 2019. The SSI rate during intervention period (9 months) was compared with baseline rate (3 months). Womens' knowledge about SSI was assessed preoperatively and after counselling, postoperatively. Results: The baseline SSI rate after CS (n = 165) was 11.1% at PGIMER and 8.5% at CH. After gynae surgery (n = 172), it was 13% at PGIMER and 11.5% at CH. During intervention, (CS = 585, gynae surgery = 503), SSI rate was reduced significantly at PGIMER (CS: 11.1% to 3.7%, P = 0.048; gynae surgery: 13% to 7.1%, P = 0.027), but not at CH (CS: 8.5% to 8.2%, P = 0.903; gynae surgery: 11.5% to 11.4%, P = 0.984). Three measures were followed more often at PGIMER than at CH: before CS, bath with hair-wash: 99.3% vs 78.5%, P = 0.00, hair-clipper vs razor: 100% vs 5.1%, P = 0.00 and antibiotic prophylaxis ≤120 min: 100% vs 92.4%, P = 0.00; and before gynae surgery, bath with hair-wash: 93.2% vs 71%, P = 0.00, hair-clipper vs razor: 93.6% vs 1.9%, P = 0.00 and antibiotic prophylaxis ≤120 min: 100% vs 80.8%, P = 0.00. Postoperatively, womens' knowledge about SSI prevention improved significantly at the two sites. Conclusion: The reduction in SSI at PGIMER was attributed to better compliance to SSI prevention measures listed above. Counselling women about simple SSI prevention method like preoperative bath with scalp hair wash increased their knowledge about these significantly.
