Prediction of hand function after occupational hand injury by evaluation of initial anatomical severity.
OBJECTIVE
To examine the relationship between initial anatomic severity evaluated by the Hand Injury Severity Scoring (HISS) system and recovered hand function evaluated by the Purdue Pegboard after occupational hand injury.


METHODS
In the retrospective cohort study, 95 patients hospitalized between 1 January 2000 and 31 December 2003 for surgery due to occupational hand injury were recruited. The HISS scores were obtained by chart review by a surgeon. The Purdue Pegboard was performed at least 6 months after the injury by well-trained occupational therapists. The Purdue Pegboard scores were compared with the initial HISS scores by simple regression, multiple regression and logistic regression analysis.


RESULTS
The total HISS score was negatively correlated with scores of the Purdue Pegboard subtests, including injured-hand, both-hands, and assembly. The risk of having low injured-hand score (<13) was significantly increased in workers with initial major severity (HISS >or= 101), with OR 9.57 (95% CI 1.4-94.8). The risk of having low both-hands score (<10) was significantly increased in workers with initial severe and major severity (HISS of 51-100 and >or=101), with OR 4.5 (95% CI 1.1-21.8) and OR 25 (95% CI 3.5-263). The risk of having low assembly score (<25) was significantly increased in workers with initial major severity (HISS >or= 101), with OR 9.0 (95% CI 1.3-72.5).


CONCLUSIONS
The study showed that after occupational hand injury, initial anatomic severity evaluated by the HISS system could predict hand function after recovery.
