Temporary staff can boost liability risk

The key: being oriented carefully

Temporary staff members working in a hospital's fast-paced emergency department (ED) are twice as likely as permanent employees to be involved in medication errors that harm patients, according to new research from The Johns Hopkins University School of Medicine in Baltimore. In addition to minimizing the use of temporary staff, the solution, say some experts, is to devote more attention to choosing the temporary staff you do use.

Results of the Johns Hopkins research raise serious issues related in particular to temporary nursing staff because they already are a substantial and growing part of the healthcare workforce, owing to the national nursing shortage, says study leader Julius Cuong Pham, MD, an assistant professor of anesthesiology and critical care medicine and emergency medicine at the school. These fill-ins plug holes in short- and long-term work schedules, and they are seen as a cheaper alternative to permanent hires, Pham notes. They often earn more per hour, but don't receive benefits, he says.

The Johns Hopkins team cautions that while it might be easy to blame the temps themselves for the errors, the problem is probably more diffuse and complex.

"A place that uses a lot of temporary staff may have more quality-of-care issues in general," Pham says. "It may not be the temporary staff that causes those errors, but a function of the whole system."

The Johns Hopkins team says that its findings do suggest, however, that the temp strategy in hospital staffing might be exacting a price in patient harm, and that temp staff's unfamiliarity with the practices and systems of a new hospital could be more costly in the long run in terms of patient safety. "Our work suggests that if you can, you probably want to avoid hiring temporary staff because they are associated with more severe medical errors," Pham says.

Pham and his colleagues did their study by examining a national Internet-based voluntary medication error reporting system and data from 2000 and 2005, which encompasses 592 hospitals and nearly 24,000 emergency department (ED) medication errors. Medication errors made by temporary workers, they found, were more likely to reach the patient, result in at least temporary harm and be life-threatening.1

Pham says that temporary personnel often are not familiar with local staff, care management systems, protocols, or procedures. This lacking of familiarity might hamper communication and teamwork, a situation that causes them difficulty in retrieving important medical information and leaves them unsure of which procedures to follow. In addition, temporary help might be less likely to speak up if they see problems, and they might also lag behind the latest knowledge because they, unlike permanent employees, typically manage their own continuing education.

"You may know the medicine," Pham said, "but you still may get tripped up by the policies and procedures of an unfamiliar system. This can lead to more serious errors."

Pham notes that the ED is a unique environment with a high risk for medication errors, likely due to the increased severity of injury or disease, the rapidity with which lifesaving decisions must be made, the medical complexities encountered, and overcrowding. Many medications are ordered, dispensed, and administered in the ED without the standard pharmacy check that occurs in nonemergency situations elsewhere in a hospital. There is a higher prevalence of verbal orders, and they often are given urgently.

Hospital administrators might not want to use temporary staff but might have no choice but to hire temporary help or be understaffed, depending on the situation, Pham says.

Some temporary nurses and doctors spend a month or two in a city and then move on, not because they can't hold down a permanent job, but because they like to travel to new places, Pham says. While some temporary employees are used in a single department over their stay to give them an opportunity to become more familiar with procedures, others are moved from unit to unit as needed, which gives them fewer opportunities to become properly prepared.

Pham says it isn't known whether a correlation between temporary workers and more serious medication errors exists in other hospital service areas. Further research is needed to determine that connection, he says.
