Defining the appropriate setting for treating obese patients: do we have the right tools?

PURPOSE

To allocate obese patients to the correct therapeutic setting, the Italian Obesity Society (SIO) has suggested a new algorithm based on the Edmonton obesity staging system (EOSS). The aim of our study was to apply in two retrospective cohorts of obese patients both the EOSS and the activities of daily life (ADL) scale to identify also their rehabilitation needs.

METHODS

288 out-patients and 298 in-patients were recruited. All patients were evaluated with a multidisciplinary approach and the mental, mechanical, and metabolic comorbidities were scored.

RESULTS

The 2 groups differed for gender (28.8% men in out-patients, p = 0.001), age (> 60 years in in-patients, p = 0.03), BMI (40.8 ± 6.3 kg/m in in-patients, p < 0.001), and ADL (44.0 ± 16.0 in in-patients, p < 0.001). EOSS distribution was significant different: stages 0 and 1 were more present in out-patients and stages 3 and 4 in in-patients. In both groups, BMI increased significantly in EOSS category [95% CI + 1.4 (+ 0.5; + 2.2) for out-patients and + 1.7 (+ 0.7; + 2.6) for in-patients] and ADL were positively correlated with EOSS [95% CI + 5.0 (+ 2.5; + 7.4) for out-patients and + 9.9 (+ 7.7; + 12.2) for in-patients]. Mean ADL difference between the two groups, adjusted for age (over/under 60 years), BMI category, and EOSS was 24.8 (p < 0.0001).

CONCLUSIONS

SIO algorithm seems an effective tool for staging obesity in relation to the clinical impairment. To better define the correct rehabilitative allocation of obese patients, we suggest to integrate the SIO algorithm with the ADL score.
