Post operation pain management for orthopedic surgeries among adults

Five articles ( qualitative and quantitative) The objective of this project which is specific, realistic, and measurable is to establish a guideline for pain management. It is for patients who have undergone an orthopedic surgery. The guideline needs to be developed because of the widespread inability of caregivers to effectively manage acute pain. The goals of this guideline are:
To determine current pain assessment practices
To provide interventions for pain management
Ninety per cent of critical care staff unit will score at least eighty per cent of the post test. This needs to be accomplished during orientation and annually thereafter.
The articles should justify why my project are worth researching on the solutions for pain management. The paper should follow the guidelines for analyzing qualitative or quantitative research report. The names of the articles( from the year 2000) and authors need to be provided.
