Design Flaws and Recommendations

Gold vs. Spree (Temperature):

Since our P-value of 1.809 x 10^-20 is so low (<0.05), we can conclude that our test was statistically significant and there is no correlation between temperature readings of the Gold device and the readings of the Spree device. This means the Spree device is not nearly as accurate as the standard Gold device and should not be used to measure temperature. We recommend that the Spree device be modified so that it has more accurate readings on temperature or to not be used at all in a clinical setting.


Gold vs. Spree (Heart rate):

Since our P-value of 0.662506 is so high (>0.05) we can conclude that our test was not statistically significant and there is a correlation between the heart rate readings of the Gold device and the readings of the Spree device. This means the Spree device was very close in terms of accuracy to the standard gold device and is an accurate way of measuring heart rate. We recommend that the Spree device can be used in a clinical setting or elsewhere.



Experimental Design of Own Device

The unique set of catheter fittings will be shipped to specific hospitals and tested over a period of many months. These will be tested against the control group of the standard Luer fittings that are currently widely used in hospitals. 10 hospitals will be the control group and 10 will be under specific protocol to use the new connectors provided. These hospitals will be of similar size and number of staff. They will both record instances of catheter misconnections and errors to provide data that can be compared. This data will be gathered for a period of six months and compared using statistical analysis to verify the effectiveness of custom fittings in preventing misconnections and patient injury
