Question

Can you please identify which is independent and dependent variable? Thanks

Abstract

Background: Medical Emergency Teams (METs) were developed in response to the low success rate of Cardiopulmonary Resuscitation (CPR). The MET process is based on recognizing a patient’s worsening condition early to avoid CPR. MET usage is still sub-optimal in Finland and many other countries. Knowledge regarding its function in practice is scarce. Thus, it is warranted to assess it. Objective: Analyzing the function of MET at Kuopio University Hospital (KUH) in Finland. Methods: In this quantitative study, the registered data, recorded by MET team per MET call activation at KUH in 2013 and 2014, were analyzed retrospectively. Descriptive statistics cross tabulation and Chi-squared test were used. Results: The distribution of MET calls varied over shifts, weekdays and months. Day shifts (70%) received more calls than night shifts (30%). Fridays received the highest proportion of MET calls (16.6%), and Sundays the lowest (11.2%).The mean time Nurse 1 spent on MET calls was 31.71 minutes (SD=16.73), while Nurse 2 spent 30.21 minutes (SD =15.57). The four most common reasons for activating MET were: “other reasons” (35.3%), “poor general condition of a patient” (33.1%), “O2 sat< 90” (27.8%) and “loss of consciousness” (22.4%). Following the MET calls, about one-fifth (20.7%) of patients were transferred to the Intensive Care Unit, 3.8% to the Intensive Cardiac Care Unit (CCU) and the rest (68.1%) remained either in the initial ward or was transferred to another ward. Conclusions: Although METs are becoming a popular patient safety initiative, there is not enough knowledge about how they function in hospital settings. There is a strong need for an international cooperation on patient safety to improve the hospitalization and healthcare quality. Impact of the study: The results of this study can be used for quality improvement of the METs function to provide more evidence to improve the patient care.

Answer 1

We are given that the Medical Emergency Teams (METs) were developed in response to the low success rate of Cardiopulmonary Resuscitation (CPR). The MET process is based on recognizing a patient’s worsening condition early to avoid CPR.

A Dependent variable is somethinng that depends on other factors .

We know an Independent variable is exactlty what it sounds like that is it is not changed by other variables that we are trying to measure.

Thus independent variable causes a change in dependent variable.

Here we see whether to avoid the early CPR on which the MET process is based on. So the we see the MET Process is dependent and CPR is independent variable.
