The aim is to evaluate the impact of an innovative asynchronous communication application on the number of calls from technologists to radiologists. Even though it is paramount that radiologists be accessible and available to other healthcare workers in the enterprise, frequent interruptions have negative impact on productivity and well-being. A novel communication app was developed that streamlines communication between technologists and radiologists: RadConnect.

| RadConnect | Device | The study will be performed in a clinical setting at the department of radiology of LUMC, meaning that we aim to test the hypothesis that ("RadConnect") can reduce the number of phone calls from a select set of extension used by technologists (the "Sending Extensions") to another select set of extensions manned by radiologists ("Receiving Extensions"). |
| Measure | Description | Time Frame |
|---|---|---|
| Test the hypothesis that adoption of RadConnect leads to reduction of phone calls to radiologists. |
The primary endpoint will be obtained by testing the hypothesis that P1 > P2 using Wilcoxon's one-tailed test with significance level P < 0.05. | Numbers are continously measured during each shift of the subjects over a period of 40 consecutive working days during the before (phase 1) and 40 consecutive working days during the after phase (phase 2) of this study. |
| Measure | Description | Time Frame |
|---|---|---|
| Compare experiences and attitudes of technicians and radiologists towards RadConnect versus phone calls. |
The first secondary endpoint will be obtained by testing the hypothesis that C1 ≠ C2 using Wilcoxon's two-tailed test with significance level P < 0.05. |

Subjects are not patients, but radiologists, technologist, doctor assistants and physician assistants employeed by LUMC. That drive the radiological workflow and frequently raise and answer questions related to the image acquisition.

| Continously measured during each shift of the subjects over a period of 40 consecutive working days during the before (phase 1) and 40 consecutive working days during the after phase(phase 2) of this study. |
| Measure the characteristics of technician questions raised over phone and through RadConnect. | • R2 = Mean number of completed RadConnect consultations per working day during regular working hours between Sending Extensions and Receiving Extensions in After Phase The second secondary endpoint will be obtained by testing the hypothesis that P1 ≠ P2 + R2 using Wilcoxon's two-tailed test with significance level P < 0.05. | Continously measured during each shift of the subjects over a period of 40 consecutive working days during the before phase (phase 1) and 40 consecutive working days during the after phase (phase 2) of this study. |
| Consolidated opinion usability and experience of RadConnect in itself and in comparison to alternative communication methods. | The third secondary endpoint will be obtained by aggregating survey responses. In the structured online survey, if more than half of the respondents indicate that they prefer communication over RadConnect to calling, it will be concluded that RadConnect is a viable alternative to calling. If more than half of radiologist respondents indicate that they believe RadConnect helps them avoid interruptions, it will be concluded that RadConnect is a viable alternative to calling that may help reduce radiologist interruptions. The opinions of study participants are captured as Likert scale response and averaged to obtain a consolidated opinion. The consolidated responses are visualized as histograms. | 1 hour, after completion of the after phase (phase 2 of this study) |
