Bone injury, vascular grafts, and high injury severity predict worse abnormal cold sensitivity.
Observational (n=182)
A CISS score >50 defines abnormal cold sensitivity in hand injuries, with severity driven by a multifactorial etiology including bony, vascular, and neural components.
Our aim was to identify a cut-off value for self-reported, abnormal cold sensitivity and to identify cold sensitivity predictors after hand injuries. The Cold Intolerance Symptom Severity (CISS) questionnaire and a VAS question concerning discomfort on exposure to cold were investigated in 94 normal people and 88 patients. A CISS score >50 was defined as abnormal cold sensitivity. Multiple injured digits, an increased number of injured vessels, complete nerve injury and replantation were variables associated with high VAS scores. Factors linked to both abnormality and worse CISS or VAS scores were: the presence of bone injury; a larger number of repaired vessels; the use of vascular grafts and a high Hand Injury Severity Score (HISS). The causes of abnormality and severity suggest a multifactorial aetiology with bony, vascular and neural components. A cut-off for abnormality is useful for descriptive, comparative and assessment purposes.

Carlsson et al. (2009) conducted an observational in Hand injuries (n=182). Hand injury characteristics (bone injury, repaired vessels, vascular grafts, high HISS) vs. Normal individuals / absence of specific injury factors was evaluated on Abnormal cold sensitivity (CISS score >50) and VAS discomfort score. A CISS score >50 defined abnormal cold sensitivity, with bone injury, increased repaired vessels, vascular grafts, and high Hand Injury Severity Score predicting worse severity.
