Background: Nursing care Process is a systematic method which utilizes scientific reasoning,rnproblem solving and critical thinking to direct nurses in caring for patients effectively. Despiternthe important role nursing process plays for the betterment of the health care, its implementationrnstatus is far below expected, particularly in developing countries. Similarly, the baselinernassessment in this project showed that the implementation of nursing care process in wacharnprimary hospital was poor. Thus, after the intervention was made the implementation of thernnursing care process completeness improved in the hospital.rnObjectives: To improve the implementation of nursing care process completeness from 10 % torn65% in medical and surgical wards of wacha primary hospital, by the end of May 2018.rnMethodology: A facility based pre- post interventional study was conducted from March 1rn tornMay 30, 2018 in Wacha Primary Hospital, Kafa Zone, South Nation Nationalities People ofrnRepublic, Ethiopia. A total of 100 Medical Records were reviewed ba s e d on HPMI rngui de l i ne of Et hi opi a (50 at baseline and 50 at the end of the study by simple randomrnsampling method) to compare the nursing c a r e Process implementation status during prernand post-intervention periods. A structured questionnaire was used to collect the data. rnResult: The percentage of patient cards with complete nursing care process increased fromrn5(10%) to 40(80%) after intervention made. Nursing admission assessment from 3(6 %) torn41(82%), Nursing diagnosis from 5(10%) to 41(82%); Nursing care plan from 6(12%) torn40(80%); Nursing implementation from 7(8%) to 40(80%) and Nursing evaluation from 5(10%)rnto 40(80%), with all changes showing there is an improvement. rnConclusion and Recommendations: Effective implementation of the nursing care process leadsrnto improve quality of care for the patient and stimulates the construction of theoretical andrnscientific knowledge of nurses on the best clinical practice. Continuous internal supportivernsupervision of nurses followed by on job training can strengthen the implementation of thernnursing care process.
