[What nurses see? Occurrence and typology of wastes in medical and surgical wards: a cross-sectional study.]

AIM: To describe the occurrence and the typology of waste in the nurses clinical practice as well as the differences between the medical and surgical area.

METHODS: A cross-sectional study was conducted in a north eastern Italian hospital. Data collection, conducted on 100 nurses in September 2015, was carried out using a semi-structured questionnaire consisting of 56 items and eight dimensions (Overproduction / Underutilisation, Wait, Stocks, Process, Inefficiency and Errors, Material Transport and Information Flows, Movements, Dispersion of Knowledge).

RESULTS: In a nurses' working week 2,028 ± 9.2 waste occurrences were reported, with an average of 20.2 ±9.2 per nurse. Seven hundred fifty-nine (37.4%) of them occurred in the medical area, while 1,269 (63.6%) occurred in the surgical area. The most frequent number of waste (398; 19.6%) occurred in the "Process" dimension. Across the investigated dimensions, the main types of waste were: the inappropriate use of energy (30.0%), waiting for the physician (17.1%), shortage of materials (33.1%), the excess of human resources distributed in a sub-optimal manner (31.8%), human resources shortage (22.4%), incomprehensible and/or incomplete therapeutic prescriptions (22.6%), the search of materials in distant warehouses or in outside locale (23.9%), the transfer of team members from one department to another (30.0%), and limited application of scientific evidence in clinical practice (51.7%). No statistical differences emerged between the two investigated clinical areas (p-value = 0.480).

CONCLUSIONS: The study is a contribution to the national debate on the phenomenon of waste in health care organizations, and provides useful insights on the possible strategies of its containment.
