I just went into GOOGLE and found tons of info on "team nursing" -- just not on the first page of results.
Having worked agency for a number of years, I've had both good and bad experiences with team nursing, depending on how the particular facility tilized the system.
Several places I've worked, as recently as three years ago, did team nursing.
Charge RN would make any necessary calls to docs, etc., check off orders (and implement orders if no secretary), coordination type stuff,
RNs would be responsible for assessments, IV meds, blood products, carrying out new orders , and delegation to LVNs and CNAs.
LVNs would do most treatments, pass po meds, IMs, prns(including insulin coverage).and possible blood products if the hospital's policy allowed it.
CNAs would assist with ADLs, do VS, weights, accuchecks if hosp policy allowed, and many incidental chores.
I found that the team system worked well when there was a charge nurse , but not all places have a charge. Then the RN on each team makes all the calls, takes off the orders, and still does patient care. Plus, for a team system to work, the team must have a reasonable patient load. I've had everything from five to fifteen patients under one team's care.
Advantages: More than one personality on the care team gives a better chance that the patient will have a caregiver they can relate to; more people are popping in and out of the patients' rooms so a problem might be noticed earlier (assuming good staff).
Disadvantages: Communication may get lost in transit from patient through the various caregivers; docs sometimes don't care who they talk to and don't understand why the verbal order given to a CNA wasn't carried out before the RN finally tracked down the doc for clarification; and, if the team is caring for a large # of patients, the RN is responsible for picking up anything that the LVN and CNA don't have time to finish.
Does this help?
