Impact of a Responsibility System Management Model on Deep Vein Thrombosis and Functional Recovery Following Internal Fixation for Pelvic Fractures.

AIM: This study evaluates the impact of a responsibility system management model in patients undergoing internal fixation for pelvic fractures, by examining the incidence of deep vein thrombosis (DVT) and postoperative pelvic functional recovery.

METHODS

This retrospective observational study included 145 patients who underwent internal fixation for pelvic fractures at Ganzhou People's Hospital between January 2022 and October 2024. Based on the nursing model, patients were categorized into a responsibility care group (n = 70), which received responsibility system management nursing care and a conventional care group (n = 75), which was managed through conventional postoperative care. The incidence of postoperative lower extremity DVT was compared between the two groups. Furthermore, pelvic function was assessed using the Majeed Pelvic Score and pain levels were evaluated using the Visual Analogue Scale (VAS). Additional parameters assessed were postoperative recovery, compliance with mechanical prophylaxis, and nursing satisfaction.

RESULTS

The responsibility system management care group demonstrated a significantly lower incidence of postoperative lower extremity DVT compared to the conventional care group (p < 0.05). Furthermore, the responsibility care group had significantly higher postoperative Majeed functional scores, lower VAS pain scores (p < 0.05), better overall recovery, longer duration of mechanical prophylaxis use, and higher nursing satisfaction (p < 0.05).

CONCLUSIONS

The responsibility system management nursing model was significantly associated with a lower risk of early DVT and better short-term pelvic functional recovery during hospitalization. This model represents a promising postoperative management strategy; however, its long-term efficacy and generalizability require further validation through multicenter prospective studies with extended follow-up.
