[National project for the clinical management of healthcare processes. The surgical treatment of cholelithiasis. Development of a clinical pathway].
BACKGROUND
Because surgical treatment of gallstones is highly prevalent, this topic is particularly suitable for a national study aimed at determining the most important indicators and developing a clinical pathway.


OBJECTIVE
To analyze the results obtained during the hospital phase of the process. To define the key indicators of the process. To design a clinical pathway for laparoscopic cholecystectomy.


METHODS
A multicenter, prospective, cross-sectional, descriptive study was performed of patients who consecutively underwent surgery for gallstones in 2002. The sample size calculated with data provided by the National Institute of Statistics was 304 patients, which was increased by 45% to compensate for possible losses. Inclusion criteria consisted of elective cholecystectomy for gallstones, without preoperative findings suggestive of common duct stones. A database was designed (Microsoft Access 2000) with 76 variables analyzed in each patient.


RESULTS
Completed questionnaires were obtained from 37 hospitals with 426 patients. The mean age was 55.69 years, with a predominance of women (68.3%). The most frequent symptom was biliary colic (23%). A total of 20.3% of the patient had prior episodes of cholecystitis and 18% had a history of mild pancreatitis. Diagnosis was given by ultrasonography in 93.2% of the patients. Informed consent was provided by 93.2%. The intervention was performed on an inpatient basis in 96.1% and in the ambulatory setting in the remainder. Antibiotic and antithrombotic prophylaxis was administered in 78.9% and 75.1% of the patients respectively. The laparoscopic approach was used in 84.6%, with a conversion rate of 4.9%. Intraoperative cholangiography was performed in 17.8% of the patients and common duct stones were found in 7 patients. The most frequent complication was surgical wound infection (1.1%). Possible accidental lesion of the biliary tract occurred in 0.7% of the patients and was described as biliary fistula. There were four reinterventions: biliary fistula (1), hemoperitoneum (2) and cause unknown (1). The mean surgical time was 73.17 minutes, with a median of 60 minutes. Postoperative length of stay was 4.75 days in open surgery and 2.67 days in laparoscopic surgery. Ninety-nine percent of the patients were satisfied or highly satisfied with the healthcare received.


CONCLUSIONS
Analysis of the process and review of the literature identified a series of areas requiring improvement, which were gathered in the clinical pathway developed. These areas consisted of increasing the number of patients with correctly indicated antibiotic and antithrombotic prophylaxis, increasing the percentage of patients providing informed consent and undergoing adequate preoperative tests, limiting intraoperative cholangiography to selected patients, and reducing the number of patients with an overall stay of 3 days.
