Objective: To perform the first randomized controlled trial to compare laparoscopic and open liver resection. Summary Background Data: Laparoscopic liver resection is increasingly used for the surgical treatment of liver tumors.However, high-level evidence to conclude that laparoscopic liver resection is superior to open liver resection is lacking. Methods: Explanatory, assessor-blinded, single center, randomized superiority trial recruiting patients from Oslo University Hospital, Oslo, Norway from February 2012 to January 2016. A total of 280 patients with resectable liver metastases from colorectal cancer were randomly assigned to undergo laparoscopic (n ¼ 133) or open (n ¼ 147) parenchyma-sparing liver resection. The primary outcome was postoperative complications within 30 days (Accordion grade 2 or higher). Secondary outcomes included cost-effectiveness, postoperative hospital stay, blood loss, operation time, and resection margins. Results: The postoperative complication rate was 19% in the laparoscopicsurgery group and 31% in the open-surgery group (12 percentage points difference [95% confidence interval 1.67–21.8; P ¼ 0.021]). The postoperative hospital stay was shorter for laparoscopic surgery (53 vs 96 hours, P < 0.001), whereas there were no differences in blood loss, operation time, and resection margins. Mortality at 90 days did not differ significantly from the laparoscopic group (0 patients) to the open group (1 patient). In a 4-month perspective, the costs were equal, whereas patients in the laparoscopicsurgery group gained 0.011 quality-adjusted life years compared to patients in the open-surgery group (P ¼ 0.001). Conclusions: In patients undergoing parenchyma-sparing liver resection for colorectal metastases, laparoscopic surgery was associated with significantly less postoperative complications compared to open surgery. Laparoscopic resection was cost-effective compared to open resection with a 67% probability. The rate of free resection margins was the same in both groups. Our results support the continued implementation of laparoscopic liver resection.

Aim To compare nursing intensity and nurse staffing costs for liver transplant (LTx) vs. kidney transplant (KTx) patients through the use of the RAFAELA system (the OPCq instrument). Background High-quality patient care correlates with the correct allocation of nursing staff. Valid systems for obtaining data on nursing intensity, in relation to actual patient care needs, are needed to ensure correct staffing. Methods A prospective, comparative study of 85 liver and 85 kidney transplant patients. Nursing intensity was calculated using the Oulu Patient Classification (OPCq) instrument. The cost per nursing intensity point was calculated by dividing annual total nursing wage costs with annual total nursing intensity points. Results The results showed significantly higher nursing intensity per day for liver transplant patients compared to kidney transplant patients. The length of stay was the most important variable in relation to nursing intensity points per day. Conclusions The study demonstrated differences in nursing intensity and nurse staffing costs between the two patient groups. Implications for Nursing Management When defending nurse staffing decisions, it is essential that nurse managers have evidence-based knowledge of nursing intensity and nurse staffing costs.
