In 1992, the Nursing Department Documentation Committee at Spaulding Rehabilitation Hospital decided to revise the process of and forms for documenting nursing diagnoses. A sub-committee developed a format for standardized nursing care plans and piloted its use on two patient care units. The unit nursing staffs selected a number of common nursing diagnoses and, using the new format, developed standardized nursing care plans for them. After refining the process based on this pilot, the development of care plans was extended to all patient care units. A collaborative partnership was then formed between interested Primary Nurses, the Psychiatric Clinical Nurse Specialist and the Nursing Practice Coordinator to focus on developing psychosocially-oriented care plans as well as physically-oriented plans. Although psychosocial diagnoses are less frequently identified in the assessment process and included in nursing care planning, they are still very important for providing comprehensive care. This article describes the process of developing and implementing psychosocial care plans. This article also describes the components of the standardized nursing care plans developed for four psychosocial nursing diagnoses.
