Objective

To analyze the relationship between the type of hospital admission (outlier and non-outlier admissions) and the appearance of clinical complications and the average stay.

Methods

From a retrospective epidemiological study of a cohort of patients admitted to the Hospital Complejo Asistencial Universitario de Salamanca (Salamanca, Spain) over a six-month period, outlier and non-outlier patients were identified. This project had access to the admissions department database, the hospital's CMBD (in Spanish, Conjunto Mínimo Básico de Datos) for hospitalisation, the AP-DRG (All Patient-Diagnosis Related Groups) and ALCOR (a clinical-statistics analytics tool). It then proceeded to break down the results by DRG, looking at the five most common DRGs in that period.

Results

8.4% of the total 11,842 admissions were medical outliers. In the overall study, the average stay was longer for outlier patients (8. 11 days) than for other patients (7.15 days). The mortality rate was, likewise, higher for outlier patients, although there was a reduced incidence of complications (7.6% for outlier patients as opposed to 8.4% for others). The analysis by DRG corroborated these results in three of the five cases investigated, showing longer average stays but fewer clinical complications in the case of outlier patients.

Conclusions

On admission to hospital, a significant proportion of patients were allocated beds on inappropriate wards (outlier patients). It was more common to find medical patients placed on surgical wards than vice versa. The average stay of outlier patients was longer than that of patients admitted to the correct ward. The study found no significant difference between the two group? in terms of clinical complication rates.  相似文献

Purpose: The authors presented their results in effectively using a free and widely-accessible online app platform to manage and teach a first-year pathology course at Mayo Medical School.

Methods used: The authors utilized the Google “Blogger”, “Forms”, “Flubaroo”, “Sheets”, “Docs”, and “Slides” apps to effectively build a collaborative classroom teaching and management system. Students were surveyed on the use of the app platform in the classroom, and 44 (94%) students responded.

Results: Thirty-two (73%) of the students reported that “Blogger” was an effective place for online discussion of pathology topics and questions. 43 (98%) of the students reported that the “Forms/Flubaroo” grade-reporting system was helpful. 40 (91%) of the students used the remote, collaborative features of “Slides” to create team-based learning presentations, and 39 (89%) of the students found those collaborative features helpful. “Docs” helped teaching assistants to collaboratively create study guides or grading rubrics. Overall, 41 (93%) of the students found that the app platform was helpful in establishing a collaborative, online classroom environment.

Conclusions: The online app platform allowed faculty to build an efficient and effective classroom teaching and management system. The ease of accessibility and opportunity for collaboration allowed for collaborative learning, grading, and teaching.  相似文献
