oa The rate of in-patient medical admissions post-bariatric surgery for medical complications during COVID-19 pandemic

Background: A rising number of bariatric surgeries (BS) are associated with a rise in medical complications including protein malnutrition and neuromuscular complications (NM). Although BS were minimized during the COVID-19 pandemic, the number of admissions due to complications continued to increase. Proper outpatient follow-up was negatively affected during the pandemic. We aim to address the rising rate of post-BS admissions during COVID-19 pandemic compared to the previous six years' admissions with a similar diagnosis. Methods: This is a retrospective observational study of 33 patients admitted with malnutrition and/or NM complications post-BS at Hamad General Hospital, Qatar, from 1st Jan 2014–30th Aug 2020. Patients’ data were retrieved from the electronic medical records and bariatric patients’ database. Malnutrition was evaluated using serum albumin, total protein, minerals, and vitamins. Nerve conduction study/electromyography confirmed NM complications. Risk factors addressed were interval between BS and admission, gastrointestinal symptoms, total weight loss (TWL %), excess weight loss (EWL %), and irregular multivitamins intake. Results: The study included 21 patients, admitted from 1st Jan 2014-31th Dec 2019, compared to 12 patients during the period 1st Jan-30th August 2020. The patients’ mean age was 26.90 ± 9.81 years, and females were 18 (59%). The mean pre-operative weight, Body Mass Index (BMI), post-operative weight, BMI were: 123.48 kg, 44.37 kg/m² and 84.61 kg – 30.67 kg/m², respectively. The mean weight loss, EWL% and TWL% was 38.04 kg, 73.26%, and 30.57%, respectively. The time interval between BS and admission was 7.18 ± 8.99 months. Seventeen patients (51.5%) had malnutrition, while 16 (58.5%) had NM complications, 87.9% were off multivitamins, and 66% had gastrointestinal symptoms. All patients showed minerals and vitamins deficiencies, especially for vitamin D (81.8%) and potassium (30.3%). Conclusion: Despite a reduction in the number of BS during the COVID-19 pandemic, an increase in the rate of hospital admissions with medical complications after BS was observed.
