A former Manitoba nurse is using social media to shed light on what she describes as growing cracks in the province’s health-care system, drawing hundreds of thousands of viewers and sparking important conversations in the process. Katrina Koop spent more than a decade working across Manitoba’s health-care system, from hospital units and private nursing to agency, infusion clinics and flight nursing. “I just wanted to make the world a better place,” Katrina said of her decision to enter nursing in 2008. Instead, she recorded a video explaining how she said the health-care system operates behind the scenes and why staffing shortages are more serious than headline numbers suggest. Katrina’s following, which pre-dated her health-care advocacy, has grown rapidly as her focus shifted to system issues that affect everyday Manitobans.
