Effects of Computerised Clinical Decision Support on Adherence to VTE Prophylaxis Clinical Practice Guidelines among Hospitalised Patients.

OBJECTIVE: Venous thromboembolism (VTE) is an important patient safety concern. VTE leads to significant mortality and morbidity and a burden on healthcare resources. Despite the widespread availability of evidence-based clinical practice guidelines on VTE prophylaxis, we found that only 50.9% of our patients were receiving appropriate prophylaxis. The purpose of this study was to evaluate the impact of automation of an adapted VTE prophylaxis CPG using a clinical decision support system (the VTE-CDSS) on VTE prevention among hospitalised adult patients. DESIGN AND SETTING: A quasi-experimental study (pre- and post-implementation) was conducted at a large 900-bed tertiary teaching multi-specialty hospital in Riyadh, Saudi Arabia. PARTICIPANTS: The 1809 adult patients in the study included 871 enrolled during the pre-implementation stage and 938 enrolled during the post-implementation stage. INTERVENTION: Multi-faceted implementation interventions were utilised, including leadership engagement and support, quality and clinical champions, staff training and education and regular audit and feedback. MAIN OUTCOME MEASURE: Two rate-based process measures were calculated for each admission cohort (i.e. pre- and post-implementation): the percentage of inpatients who were assessed for VTE risk on admission and the percentage of inpatients who received appropriate VTE prophylaxis. Two outcome measures were calculated: the prevalence of hospital-acquired VTE (HA-VTE) events and the in-hospital all-cause mortality. RESULTS: The percentage of inpatients risk assessed for VTE on admission increased from 77.4% to 93.3% (P < 0.01). The percentage of patients who received appropriate VTE prophylaxis increased from 50.9% to 81.4% (P < 0.01). The HA-VTE events decreased by 50% from 0.33% to 0.15% (P < 0.01).All-cause in-hospital mortality did not significantly change after implementation of the VTE-CDSS compared with pre-implementation mortality (P > 0.05). CONCLUSION: The VTE-CDSS improved patient safety by enhancing adherence to the VTE prophylaxis best practice and adapted CPG. The multi-faceted implementation strategies approach improved the compliance rate of risk assessment and the adherence to prophylaxis recommendations and substantially reduced the HA-VTE prevalence. A successful CDSS requires a set of critical components to ensure better user compliance and positive patient outcomes.

Prevalence of diabetes, management and outcomes among Covid-19 adult patients admitted in a specialized tertiary hospital in Riyadh, Saudi Arabia.

This retrospective study aimed to characterize comorbidities and associated with mortality among hospitalized adults with Covid-19 managed as perthe Saudi Ministry of Health protocol in a specialized tertiary hospital in Riyadh, Saudi Arabia. Medical records of 300 adult patients with PCR-confirmed SARS-CoV2 infection and admitted in King Salman Hospital (KSH) from May 1 to July 31, 2020 were included. Medical history, management and outcomes were noted. Males significantly outnumber females (259 versus 41). South Asians comprise 41% of all admitted patients. Mortality rate was 10% and highest among Saudi males (28.9%). Type 2 diabetes mellitus (T2DM) was the most common comorbidity (45.7%). Almost all patients (99%) had pneumonia. Patients > 50 years were three times more likely to die (confidence interval, CI 1.3-6.9; p = 0.01) from Covid-19. Congestive heart failure (odds ratio OR 19.4, CI-1.5-260.0; p = 0.02) and acute kidney injury (OR 11.7, CI-4.7-28.6; p < 0.001) were significantly associated with higher mortality. Dexamethasone use significantly improved the final outcome based on net reclassification improvement (NRI) and integrated discrimination improvement (IDI) (p < 0.05). In this single-center study, T2DM was very common among hospitalized Covid-19 patients. Patients > 50 years, those with congestive heart failure and acute kidney injury are at higher risk for worse Covid-19 outcome.

Descending necrotizing mediastinitis.

Descending necrotizing mediastinitis (DNM) is a rare but severe life threatening complication of oropharyngeal infections. We report a young lady who had severe pharyngitis complicated by anterior neck infection that descended to the mediastinum causing necrotizing mediastinitis. The course of her illness was complicated with septic shock, acute kidney injury, tracheo-esophageal fistula, and critical illness polyneuropathy. There was considerable delay in her diagnosis; however, she survived after aggressive surgical intervention, wide spectrum antibiotics, and appropriate intensive care management. Early and repeated chest imaging using computed tomography was vital for the detection and follow up of this case. There is a need to increase physicians' awareness of this condition that can complicate odontogentic or pharyngeal infection, procedures, or trauma.
