Knowledge, attitudes and practices of healthcare workers during the early COVID-19 pandemic in a main, academic tertiary care centre in Saudi Arabia.

As the Middle East respiratory syndrome coronavirus (MERS-CoV) continues to occur in small outbreaks in Saudi Arabia, we aimed to assess the knowledge, attitudes and intended practices of healthcare workers (HCWs) during the early stage of the COVID-19 pandemic and compare worry levels with previous findings during the MERS-CoV outbreak in 2015. We sent an adapted version of our previously published MERS-CoV questionnaire to the same cohort of HCWs at a tertiary hospital in Saudi Arabia. About 40% of our sample had previous experience with confirmed or suspected MERS-CoV patients, and those had a significantly higher knowledge score (13.16 ± 2.02 vs. 12.58 ± 2.27, P = 0.002) and higher adherence to protective hygienic practices (2.95 ± 0.80 vs. 2.74 ± 0.92, P = 0.003). The knowledge scores on COVID-19 were higher in the current cohort than the previous MERS-CoV outbreak cohort (68% vs. 79.7%, P < 0.001). HCWs from the current cohort who felt greater anxiety from COVID-19 compared to MERS-CoV were less likely to have been exposed to MERS-CoV infected/suspected cases (odds ratio (OR) = 0.646, P = 0.042) and were less likely to have attended the hospital awareness campaign on COVID-19 (OR = 0.654, P = 0.035). We concluded that previous experience with MERS-CoV was associated with increased knowledge and adherence to protective hygienic practices, and reduction of anxiety towards COVID-19.

Clinical and therapeutic features of brucellosis: An 11-year study at a tertiary care hospital in Riyadh, Saudi Arabia.

To study the varying presentations, risk factors, and treatment outcomes among patients with physician-diagnosed brucellosis. This retrospective analysis evaluated all cases of brucellosis reported at King Khalid University Hospital during 2003-2013. Data were retrieved from patient records and a laboratory information system. Descriptive statistics were generated to summarize the study variables. Fisher's exact test or Pearson's chi-square test was used to compare categorical variables. Out of 163 patients identified with brucellosis, 76.7% of patients were culture positive. Fever was the most frequent symptom (85.9%), followed by arthralgia (46.6%). The most common clinical signs was splenomegaly (12.9%), followed by hepatomegaly (11.0%). Laboratory investigations revealed lymphocytosis and anemia in 66.3% and 55.2% of the patients, respectively. Approximately half of the patients (47.8%) had high erythrocyte sedimentation rates, and 56.4% had neutrophilia. Raw milk consumption and direct contact with animals were reported by 45.4% and 16.0% of patients, respectively. Treatment failure and relapse were observed in 8 (5.7%) cases. All treatment failures and relapses occurred among children <= 10 years of age or adults > 45 years old (11.0% vs. 0%; p = 0.006). Our findings demonstrate that raw milk consumption can be a substantial factor in brucellosis prevention in Saudi Arabia. Laboratory findings, along with the observed pattern in clinical signs and symptoms, can potentially mean underdiagnosis of mild cases. Age was the only factor associated with unfavorable treatment outcomes.
