- Background: Laparoscopic surgery for colorectal cancer has been shown in clinical trials to be effective regarding short-term outcomes and oncologically safe. Health economic analyses have been performed early in the learning curve when adoption of laparoscopic surgery was not extensive. This cost-effectiveness analysis evaluates laparoscopic versus open colorectal cancer surgery in Swedish routine care. Methods: In this national retrospective cohort study, data were retrieved from the Swedish ColoRectal Cancer Registry. Clinical effectiveness, resource use and unit costs were derived from this and other sources with nationwide coverage. The study period was 2013 and 2014 with 1 year follow-up. Exclusion criterion comprised cT4-tumors. Clinical effectiveness was estimated in a composite endpoint of all-cause resource-consuming events in inpatient care, readmissions and deaths up to 90days postoperatively. Up to 1 year, events predefined as related to the primary surgery were included. Costs included resource-consuming events, readmissions and sick leave and were estimated for both the society and healthcare. Multivariable regression analyses were used to adjust for differences in baseline characteristics between the groups. Results: After exclusion of cT4 tumors, the cohort included 7707 patients who underwent colorectal cancer surgery: 6060 patients in the open surgery group and 1647 patients in the laparoscopic group. The mean adjusted difference in clinical effectiveness between laparoscopic and open colorectal cancer surgery was 0.23 events (95% CI 0.12 to 0.33). Mean adjusted differences in costs (open minus laparoscopic surgery) were $4504 (95% CI 2257 to 6799) and $4480 (95% CI 2739 to 6203) for the societal and the healthcare perspective respectively. In both categories, resource consuming events in inpatient care were the main driver of the results. Conclusion: In a national cohort, laparoscopic colorectal cancer surgery was associated with both superior outcomes for clinical effectiveness and cost versus open surgery. © 2019, The Author(s).

- Objectives: For medical devices, benefits other than direct clinical effects may have a large impact on the patients' well-being, but a standardized method for measuring these benefits is unavailable. The objective was to explore potential patient benefits provided by medical devices, and to assess the relative preferences of these benefits in the general Swedish population. Methods: To identify attributes of patient benefit, healthcare personnel within a wide range of disease areas were interviewed. The generalized attributes were then validated among healthcare personnel, patient organizations, and manufacturers; in two pilot studies in the general population; and in two rounds of cognitive interviews. The general population's preferences of the attributes were measured with a usability-tested questionnaire in a final responding sample of 3,802 individuals, representative of the Swedish population. Results: Twenty attributes were identified, encompassing aspects of integrity, sense of security, social participation, and convenience. When measuring the relative preferences, the response rate was 37.0 percent, and the results showed that the attributes with the highest preferences concerned reliability, reduced need for assistance, and sense of control of the illness/disability. Conclusions: A set of twenty attributes of patient benefit relevant to users of medical devices was identified and validated. A questionnaire for patient-reported assessment of the benefits provided by a medical device was developed, based on the attributes. The questionnaire, designated MedTech20, provides a generic measurement method for the evaluation of medical devices used in a wide range of diseases/disabilities.

- ObjectivesWarfarin-treated patients with poor international normalized ratio (INR) control, measured with time in therapeutic range (TTR) or the standard deviation of transformed INR (SDTINR), have an increased risk for clinical events. To what extent only a short period with an altered INR control may influence outcomes remains unknown. This study assessed the impact of transient periods of improved or worsened INR control on life expectancy and quality-adjusted life years (QALYs) among warfarin-treated patients with atrial fibrillation (AF) using both metrics.MethodsWarfarin-treated patients with AF, registered in the patient record system Journalia during years 1985-2000, were included. Information on all-cause mortality was collected from the Cause of Death Register. Scenarios where patients were assumed to have a transiently altered INR control during 30 days were modeled statistically using hazard functions, and the impact on remaining life expectancy and QALYs was assessed.ResultsWhen using SDTINR, a 70-year old man within the 2.5th worst INR control percentile was estimated to gain 10.8 days of life or 0.0168 QALYs from a 30-day improvement in INR control to that of an average 70-year old man. Correspondingly, 15.5 days of life or 0.0196 QALYs would be lost if a 70-year old man within the 2.5th best INR control percentile would have an average INR control during 30 days. The magnitudes were smaller when TTR was used to determine INR control.ConclusionsEven short periods of altered INR control is expected to have impact on life expectancy and QALYs among patients with AF.
