Screening for Medication Errors and Adverse Events Using Outlier Detection Screening Algorithms in an Inpatient Setting.

OBJECTIVES: To evaluate the potential of a novel system using outlier detection screening algorithms and to identify medication related risks in an inpatient setting. METHODS: In the first phase of the study, we evaluated the transferability of models refined at another medical center using a different electronic medical record system (EMR) on 3 years of historical data (2017-2019), extracted from the local EMR system. Following the retrospective analysis, the system's models were fine-tuned to the specific local practice patterns. In the second, prospective phase of the study, the system was fully integrated in the local EMR and after a short run-in period was activated live. All alerts generated by the system, in both phases, were analyzed by a clinical team of physicians and pharmacists for accuracy and clinical relevance. RESULTS: In the retrospective phase of the study, 226,804 medical orders were analyzed, generating a total of 2731 alerts (1.2% of medical orders). Of the alerts analyzed, 69% were clinically relevant alerts and 31% were false alerts. In the prospective phase of the study, 399 alerts were generated by the system (1.6% of medical orders). The vast majority of the alerts (72%) were considered clinically relevant, and 41% of the alerts caused a change in prescriber behavior (i.e. cancel/modify the medical order). CONCLUSION: In an inpatient setting of a 600 bed computerized decision support system (CDSS) -naïve medical center, the system generated accurate and clinically valid alerts with low alert burden enabling physicians to improve daily medical practice.

Evaluation of SARS-CoV-2 in the Vaginal Secretions of Women with COVID-19: A Prospective Study.

OBJECTIVE: We aimed to investigate the likelihood of vaginal colonization with Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pregnant and non-pregnant women with Coronavrus Disease 2019 (COVID-19). MATERIALS AND METHODS: Vaginal swabs were taken from women diagnosed with mild to moderately acute SARS-CoV-2 infection, at Wolfson Medical Center, Israel, from March 2020 through October 2020. COVID-19 was diagnosed by real-time polymerase chain reaction (RT-PCR) performed on nasopharyngeal swabs. Vaginal swabs were tested for the presence of SARS-CoV-2 by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: In total, 51 women diagnosed with COVID-19 were included in the study. Of the 51 women with COVID-19 enrolled in this study, 16 (31.4%) were pregnant at enrollment and 35 (68.6%) were non-pregnant. Mean age was 43.5 ± 15.3 years (range 21-74 years). Compared to the non-pregnant group, the pregnant group was characterized by a higher white blood cell and absolute neutrophil count (p = 0.02 and p = 0.027, respectively). The non-pregnant patients were more likely to have chronic diseases (p = 0.035) and to be hospitalized (p < 0.001). Only one patient (1.9%) aged 60 years tested positive for SARS-CoV-2 in vaginal secretions. Mean gestational age at the diagnosis of COVID-19 of the pregnant group was 32.3 ± 7.8 weeks. Thirteen patients delivered during the study period; all delivered at term without obstetric complications and all neonates were healthy. CONCLUSIONS: Detection of SARS-CoV-2 in the vaginal secretions of patients diagnosed with COVID-19 is rare. Vaginal colonization may occur during the viremia phase of the disease, although infectivity from vaginal colonization needs to be proven.

Validating the Hebrew version of the Person-Centered Care of Older People with Cognitive Impairment in Acute Care scale.

AIM: To validate the Hebrew version of the Person-Centered Care of Older People with Cognitive Impairment in the Acute Care scale. BACKGROUND: The Person-Centered Care of Older People with Cognitive Impairment in Acute Care scale is a reliable and valid measure to assess the extent to which person-centred care among people with dementia is adopted in the acute care setting. METHODS: A cross-sectional study using a self-reporting structured questionnaire was conducted with 678 professionals (69% nurses, 26% physicians, 5% other health care professionals) in five hospitals across Israel. RESULTS: Similar to other languages, best results were obtained using 14 of the 15 items included in the original scale. Confirmatory factor analysis indicated the appropriateness of a three-factor structure for the Hebrew version of the scale. Cronbach's alpha scores for these factors were moderate to good. CONCLUSIONS: The Hebrew version of the scale is a reliable and valid tool for assessing hospital professionals' perceptions of person-centred care. IMPLICATIONS FOR NURSING MANAGEMENT: A new language validated version of the scale will allow nurse managers to learn from multiple countries' experience while conducting international comparisons. Such developments will improve and expand the implementation of the person-centred care among people with dementia in hospital settings.

[WOLFSON MEDICAL CENTER - PAST, PRESENT AND FUTURE].

INTRODUCTION: The Wolfson Medical Center was established forty years ago, in 1980, with the aim of providing residents of the surrounding cities with medical services of international standards. It has about 700 hospital beds. The population served by the Wolfson Medical Center numbers about one million residents, from the cities of Bat Yam, Holon, Rishon Lezion and Tel Aviv-Yafo. This population is very diverse, and includes patients of a wide age range, residents of all religions and cultures, religious and secular, people of socioeconomic and educational status from a broad spectrum, foreign workers, refugees and residents of countries from all over the world. This diversity reflects the unique challenges facing Wolfson Medical Center. As part of the activities of "Save a Child's Heart" over 5,000 children with congenital heart defects from 65 countries around the world have been operated on in Wolfson in the last 25 years. As part of the joint work with "Save a Child's Heart", the new Children's Hospital will be opened in the coming months. In this issue, we will present works that reflect the diversity of clinical and research work at the medical center.

Hyperuricemia attenuates aortic nitric oxide generation, through inhibition of arginine transport, in rats.

OBJECTIVES: Hyperuricemia provokes endothelial dysfunction (ECD). Decreased endothelial nitric oxide synthase (eNOS) activity is an important source of ECD. Cationic amino acid transporter-1 (CAT-1) is the specific arginine transporter for eNOS. We hypothesize that hyperuricemia inhibits arginine uptake. METHODS: Experiments were performed in freshly harvested aortas from untreated animals and rats fed with oxonic acid (hyperuricemia), and compared to hyperuricemic rats treated with either allopurinol, benzbromarone or arginine. RESULTS: Arginine transport was significantly decreased in hyperuricemia. Benzbromarone and arginine prevented the decrease in arginine transport in hyperuricemic rats while allopurinol did not. Arginine transport was significantly decreased in control rats treated with allopurinol. Blood pressure response to acetylcholine was significantly attenuated in hyperuricemic rats, an effect which was prevented in all other experimental groups. L-NAME inhibitable cGMP response to carbamyl-choline was significantly decreased in hyperuricemic rats and this was completely prevented by both benzbromarone and arginine, while allopurinol partially prevented the aforementioned phenomenon. Hyperuricemia induced a significant increase in protein nitration that was prevented by benzbromarone, allopurinol, and arginine. Protein abundance of CAT-1, PKCα, and phosphorylated PKCα remained unchanged in all experimental groups. CONCLUSIONS: In hyperuricemia, the decrease in aortic eNOS activity is predominantly the result of attenuated arginine uptake.
