Patient-Reported Mental Health Outcomes After Single-Digit Non-thumb Traumatic Amputation in Adults.

Abstract

Background: Though traumatic digital amputations are common, outcomes data are scarce. The FRANCHISE study clarified functional outcomes after digital amputation, but little information is available regarding mental health outcomes. The aims of this study were to document patient-reported mental health outcomes after traumatic digital amputation, elucidate the relationship between mental health and functional outcomes, and determine which patient/injury attributes conferred risk of unfavorable mental health outcomes.

Methods: This was a descriptive, retrospective study of 77 patients with history of single digit, non-thumb traumatic amputation. Eligible patients completed Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity, Pain Interference, Anger, Anxiety, and Depression computer adaptive tests, and a short questionnaire recorded handedness, demographics, and worker's compensation status.

Results: Correlation across the 3 PROMIS mental health domains (Anger, Anxiety, Depression) was uniformly strong and statistically significant. Correlation between the PROMIS mental health and functional (Upper Extremity and Pain Interference) scores was statistically significant but much weaker. Multivariable analysis revealed younger age and a worker's compensation claim had independent statistically significant predictive value for worse PROMIS Anger, Anxiety, and Depression scores. Female sex was also found to independently predict PROMIS Anxiety.

Conclusions: By identifying patients at increased risk for feelings of anger, anxiety, and depression after digital amputation, anticipatory counseling can be provided. Anger, anxiety, and depression are very likely to coexist in the same patient; when responding to a patient who exhibits 1 element of this triad, the surgeon should be aware that the other 2 elements are likely to be present, even if not obvious.
