Overtime Puts Your Staff at Risk

The link between overworked nurses and patient safety has been well established[i],[ii], but there are other safety factors that aren’t talked about as much even though they should be. In industries where overtime is a factor, workplace safety issues are a major concern.

Regardless of industry, jobs with overtime schedules lead to workplace injury hazard rates that are as high as 61% when compared to jobs that don’t operate with overtime schedules[iii]. In fact, simply working as much as 12 hours in a single day leads to a 37% increase in injury rates[iv]. For those of us who work in healthcare these numbers should be cause for concern.

Industry-wide about 50% of full-time nurses work overtime[v], which means their exposure to injury risk is increased. As an industry, healthcare experiences higher injury rates than others. We work in an always-open environment and the work is often physically challenging. In fact, the rate of injury in healthcare is actually two times greater than normal. For an average hospital the cost of nurse injuries can easily climb to $440,000 annually[vi].

However, beyond the tangible cost and impact to the budget there are other costs that should be equally concerning. Nursing assistant injuries have been associated with lower employee satisfaction, increased desire to quit, and a decreased likelihood of recommending the facility for either treatment or as employer[vii]. In an accountable-care business model where financial and clinical metrics are linked to success, employee satisfaction creates a trickle down impact on several factors, including quality care and patient satisfaction.

When overtime is increasingly becoming the rule and not the exception, we need to step back and rethink how we optimize our workforce to ensure employee safety, patient safety and the health of the organization’s bottom line.  To learn more, read the white paper, “Adding It Up – Accounting for the Transformational Power of an Optimized Workforce.”
