Objective To evaluate the feasibility of the clinical pathway based on the medical data information integration system to guide the treatment of palmar hyperhidrosis (PHH). Methods We retrospectively analyzed the clinical data of 106 PHH patients in the Fourth Affiliated Hospital of Harbin Medical University from March 2012 through June 2015. The patients were divided into two groups including a day surgery group (52 patients) and a traditional group (54 patients). The patients in the day surgery group underwent day surgery guided by clinical pathway of PHH based on medical data information integration system. The patients in the traditional group stayed in hospital for 2-3 days. The pre-surgical situation, post-surgical effect of patients and cost of hospitalization were compared between the two groups. Results Only one patient of PPH suffered from insufficient relief of symptoms. The other patients’ symptom of PPH disappeared. No serious complication occurred. The postoperative visual analogue scale (VAS) pain score of patients was lower than 2 points. The hospitalization expense of the day surgery group was significantly lower than that of the traditional operation group. The average follow-up time was 2.5 months (0.5 to 4 months). The symptoms of the whole group had no recurrence. All of the patients were not found with compensatory hyperhidrosis. Conclusion Day-surgery clinical pathway of PHH based on medical data information integration system is safe and feasible. Day-surgery clinical pathway of PPH can accelerate the recovery of patients and save the cost of hospitalization.
