Ask an answerable question (PICO)：
Build up a clinical question: explore that use the Bed-Exit alarm system could show result to prevent the inpatient fall down. PICO - P: inpation ; I:use the Bed-Exit Sensor ; C:usual care ; O:rate of falls.
The Method and Analysis of Literature Review：
The literature searching database includes PubMed,CEPS,Cochrane, Embase, Clinicalkey
Keywords are includes as follows: P (Inpatient), I(Sensor, Bed exit alarm, Bed alarm, Technology, Monitoring, Telemedicine, Alarms), C(Usual care), O(Fall prevention, Reduce falls, Accident Prevention/instrumentation, Accidental Falls/prevention & control,rate of falls),Keywords is corresponding with PICO , and the sequence of PICO keywords: ” P&I→O→C”; combine text words/keywords/MeSH term searching with Boolean characters “OR, AND, NOT ” ; the languages selected are Chinese and English.
Critical Appraisal：
Qualified critical appraisal of literature- the searching results: there are total 43 articles found in Chinese and English literature databases; by deducting and removing the literature with issue of duplicate, use other intervention, the title isn’t accordance the article, the test group isn’t used the sensor bed and no control group, a total 3 articles of literature are being appraised ,with the appraising tool of CASP in the version of 2018.
Clinical Application of Evidence：
Use the 7 steps empirical knowledge translation to improve, implement and analyze the results at the same time, during the study period, from January 1, 2020 to August 31, 2020; performed in the Oncology ward of a regional teaching hospital in the North, it is aimed at the standard patients who correspond with Oncology’s use the Bed-Exit alarm.
Evaluation of Effectiveness：
According to the data from the Patient-Safe Bulletin of this hospital, the period from January 1, 2020 to August 31, 2020 the patients who agree used the Bed-Exit alarm system total 83 persons, make use of the Bed-Exit alarm system patient are 67 actually, total 1,236 patients used it per day, include 10 patients fell, the rate of falls was 0.81%(10/1,236), it was 0 event of fall at bedside.
Conclusions and Recommendations：
This article explores that use the Bed-Exit alarm system
could prevent the inpatient fall down effectively. Based on the empirical inquiry and clinical application, PICO is formed to use the empirical medical strategies to search and screen the relevant literature, and strictly evaluate 3 literatures. The evidence show that use the Bed-Exit alarm system is not effective prevent the inpatient fall down, but consider if patient falls may cause the burden to the Healthcare system so apply it in clinical. Applicable result: the rate of falls was 0.81%(10/1,236),the rate of falls in the Oncology Ward is 0.07%(13/17,102). After use the Bed-Exit alarm system. Although that is not obvious effect after use the Bed-Exit alarm system, however it was 0 event of fall at bedside; the bed side alarm main function is immediate find and prevention then applying help, maybe this main function can effect prevent the event of bedside falls. Now difficult situation is that the nurses too busy to immediate reach the bedside when the alarm ringing, and the family or the patient reject install this system. We should strengthen the patient and the family know the Bed-Exit alarm system to attain the goal of prevention falls together. Suggestion that could express the prevention function if make the system connect with the nursing’s cart, nursing’s alarm system and the family’s mobile. Hope that empirical the Evidence-based result let more participant would like to join the research, afford the patient better and safer care equipment.
