Nurse managers' decision-making in daily unit operation in peri-operative settings: a cross-sectional descriptive...

To describe the tactical and the operational decisions made by nurse managers when managing the daily unit operation in peri-operative settings.

Management is challenging as situations change rapidly and decisions are constantly made. Understanding decision-making in this complex environment helps to develop decision support systems to support nurse managers' operative and tactical decision-making.

Descriptive cross-sectional design.

Data were collected from 20 nurse managers with the think-aloud method during the busiest working hours and analysed using thematic content analysis.

Nurse managers made over 700 decisions; either ad hoc (n = 289), near future (n = 268) or long-term (n = 187) by nature. Decisions were often made simultaneously with many interruptions. Ad hoc decisions covered staff allocation, ensuring adequate staff, rescheduling surgical procedures, confirmation tangible resources and following-up the daily unit operation. Decisions in the near future were: planning of surgical procedures and tangible resources, and planning staff allocation. Long-term decisions were: human recourses, nursing development, supplies and equipment, and finances in the unit.

Decision-making was vulnerable to interruptions, which sometimes complicated the managing tasks.

The results can be used when planning decision support systems and when defining the nurse managers' tasks in peri-operative settings.
