Investigation of the Effect of Ergonomic Intervention on Medical Emergency Announce Time of Dispatch in Alborz

Effective communication is an important factor in pre-hospital care. The emergency medical communication and dispatch center is one of the most stressful work environments in the healthcare domain so that it is essential to assess the harmful factors associated with this work environment. According to the guidelines of pre-hospital emergency procedures, it should take 120 seconds from the triage nurse response to the moment the mission is announced. The present study aimed to investigate the effect of ergonomic status at the workplace on the time of the announcement of the mission to dispatch personnel working at emergency medical communication and dispatch center. This study was conducted based on a descriptive-interventional design. In total, 36 participants were randomly selected from emergency medical communication and dispatch center. The data were collected using luxmeter, sound meter, and rapid office strain assessment. This study evaluated the time of the mission announcement by the communication and dispatch staff. The data were analyzed through descriptive statistics. P-value less than 0.05 was considered statistically significant. According to the results, the intervention affected the time of call registration and the mission assignment. The measured time before the intervention was 2.02s which decreased to 1.92s after the intervention. Therefore, the results indicated that the intervention significantly contributed to the differences between the times of registration until the mission assignment. It can be concluded that the improvement of ergonomic status can have effects on the staffs' performance.
