yes, i certainly do believe in team nursing!!!
a few years back, i worked at a large hospital in an oncology unit where we had a nurse manager who was very prostaff involvement. we pioneered the concept of the rn/cna team with the rn actually interviewing and hiring her/his own partner. each team worked the same schedule.
the rn was then responsible for training/orienting her cna. as the team grew together, they became a very strong unit, knowing precisely what each other was responsible for and communicating each other's and the patients' needs in a very accurate and proficient manner. average patient load per team was 8.
it was so successful that other units adapted our rn/cna concept. however, when the rns were not allowed to select their own permanent team member, the results were no where near the same. personality and responsibility problems were abundant!
i currently work in a hospital that has no cna's, only licensed staff. "teams" are made up of rns and lvns, but there is no continuity to these teams. each pair is responsible for 10-12 patients, with one doing meds/assessments/admits/discharges, and the other doing adl's/vs/i&o. so, you have two licensed nurses per team, but they are so busy trying to get the basics done, that they do not have time to learn the other's strengths and weaknesses. thereby preventing the formation of a more effective, cohesive team.
it does not work!
in summary: the team concept is great!!! however, it must be a well-thought out plan with consideration for both staff and patients.
