Pain Characteristics of Adults 65 Years of Age and Older Referred to a Tertiary Care Pain Clinic
Bibliographic record
Abstract
BACKGROUND: Reports indicate that characteristics of older adults with chronic pain may be different than those of younger persons. OBJECTIVE: To study the pain characteristics of older patients presenting to a tertiary pain clinic for the first time. METHODS: Age, sex and relative contributions of biomedical versus psychosocial variables contributing to chronic pain were investigated in patients 65 years of age and older, in comparison with younger patients, from a sample of 1242 consecutive new patients attending a tertiary care pain clinic. The presence of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision somatoform pain disorders were defined, using an explicated method of ascertaining the biomedical and psychological variables underlying the pain complaints. RESULTS: The older patients (14.7% of the total sample) had relatively more physical problems (concordant with their complaints) but fewer psychological factors contributing to disability than the younger pain patients. Musculoskeletal and neuropathic disorders affected 40.7% and 35.2% of the older patients, respectively, while several patients had more than one painful disorder. Musculoskeletal problems were more prevalent in the women, and neuropathic problems were more prevalent in the men. CONCLUSIONS: The older pain patients are a distinct group. Factors affecting the delayed presentation of older pain patients to the pain clinic and limitations of the present study are discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
