Studies Using OACIS Return to Work Survey

The OACIS Return to Work survey focuses on understanding the impact of patients’ hospital stay experience on their ability to return to usual activity. It primarily consists of collecting details about the employment status, occupation, working hours, activities performed at work, effectiveness in their job, etc.

Below are example publications and study protocols that include OACIS Return to Work Survey.
