[The Mainz Pain Staging System is also suitable for grading chronic pain in inpatient geriatric patients]

The Mainz Pain Staging System (MPSS), which has been validated primarily in middle-aged and chronic low back pain patients, is designed to predict prognosis and control the use of resources at baseline. In multi-morbid and functionally impaired patients (geriatric patients) with multiple causes of pain, it is unclear whether this instrument can be implemented at all and whether it permits statements to be made on the severity of pain chronification.

Therefore, 173 consecutive patients with pain were classified in the second week of inpatient geriatric treatment according to the MPSS. For validation, the questions from the "Pain interview for geriatric patients" (SgP) were used. In addition, the MPSS was compared with the personal history of the duration of the main pain.

With the exception of the questions on medication intake, the items in the MPSS could be collected predominantly by self-assessment. Even with current analgesic therapy, MPSS has significant correlations with sensory, affective, and emotional dimensions of pain from the SgP. The data on duration correlated with only one category of MPSS (spatial aspects of pain).

MPSS can be used in multi-morbid and functionally impaired elderly patients undergoing inpatient treatment. Chronification features are more pronounced at higher stages than at lower levels. Only one category of the MPSS cannot be collected by self-assessment. The possibilities of prognosis estimation and resource control using the MPSS should be further investigated for these patients.
