Objective:
Response-shift has been cited as an important measurement consideration when assessing patient reported quality of life (QoL) outcomes over time among patients with severe chronic conditions. Here we report the results of a systematic review of response shift in studies assessing QoL among cancer patients.
Methods:
A systematic review using MEDLINE, EMBASE, and PsychINFO along with a manual search of the cited references of the articles selected, was conducted. A quality review was performed using STROBE criteria and reported according to PRISMA guidelines.
Results:
A systematic review of 1,487 records published between 1,887 and December 2018 revealed 104 potentially eligible studies, and 35 studies met inclusion criteria for content and quality. The most common cancer patient populations investigated in these studies were breast (18 studies), lung (14 studies), prostate (eight studies), and colorectal (eight studies). Response shift was identified among 34 of the 35 studies reviewed. Effect sizes were reported in 17 studies assessing QoL outcomes among cancer patients; 12 of which had negligible to small effect sizes, four reported medium effect sizes which were related to physical, global QoL, pain, and social (role) functioning and one reported a large effect size (fatigue). The most prevalent method for assessing response shift was the
then-test
, which is prone to recall bias, followed by the
pre-test and post-test
method. Given the heterogeneity among the characteristics of the samples and designs reviewed, as well as the overall small to negligible effect sizes for the effects reported, conclusions stating that changes due to internal cognitive shifts in perceived QoL should account for changes observed in cancer patients' QoL outcomes should be interpreted with caution.
Conclusion:
Further work is needed in this area of research. Future studies should control for patient characteristics, time elapsed between diagnosis and baseline assessment and evaluate their contribution to the presence of response shift. Time between assessments should include short and longer periods between assessments and evaluate whether the presence of response shift holds over time. Possible avenues for inquiry for future investigation are discussed.
Identifying the barriers and facilitators to patient and caretaker engagement in decision making is a key step in the development of a structured, patient-centered SDM approach. Intervention early in the decision process, the use of individualized decision aids that employ graphic risk presentations, and a dedicated decisional coach were identified by patients and providers as approaches with a high potential for success. The impact of such a formalized shared decision making process in cardiac surgery on decisional quality will need to be formally assessed. Given the trend toward older and frail patients referred for complex cardiac procedures, the need for an effective shared decision making process is compelling.
Background: The Carpentier-Edwards Perimount valves have a proven track record in aortic valve replacement: good durability, hemodynamic performance, rates of survival, and low rates of valve-related complications and prosthesis-patient mismatch. The St. Jude Medical Trifecta is a newer valve that has shown comparable early and midterm outcomes. Studies show reoperation rates of Trifecta are comparable with Perimount valves, with a few recent studies bringing into focus early structural valve deterioration (SVD), and increased midterm SVD in younger patients. Given that midterm data for Trifecta is still sparse, we wanted to confirm the early low reoperation rates of Trifecta persist over time compared with Perimount. Methods: The Maritime Heart Centre Database was searched for AVR between 2011 and 2016, inclusive. The primary endpoint of the study was all-cause reoperation rate. Results: In total, 711 Perimount and 453 Trifecta implantations were included. The reoperation hazards were determined for age: 0.96 (0.92-0.99; p = .02), female (vs. male): 0.35 (0.08-1.53; p = .16), smoker (vs. nonsmoker): 2.44 (0.85-7.02; p = .1), and Trifecta (vs. Perimount): 2.68 (0.97-7.39; p = .06). Kaplan-Meier survival analysis in subgroups-age <60, age ≥60, male, female, smoker, and nonsmokershowed Perimount having lower reoperation rates than Trifecta in patients younger than 60 (p = .02) and current smokers (p < .01). Conclusions: The rates of reoperation of Perimount and Trifecta were comparable, with Trifecta showing higher rates in patients younger than 60 years, and current smokers. Continued diligence and further independent reporting of midterm reoperation and SVD rates of the Trifecta, including detailed echocardiographic follow-up, are needed to confirm these findings.
Background
Aortic valve replacement (AVR) is one of the most common open‐heart surgical procedures. The durability of the tissue valve in the aortic position is crucial in AVR and transcatheter AVR. We reviewed structural valve deterioration using echocardiographic follow‐up in three types of surgical aortic tissue valves.
Methods
A retrospective analysis was conducted where hemodynamic deterioration was evaluated and compared using transthoracic echocardiography, including pressure gradients and effective orifice area. Kaplan–Meier analyses were used to summarize the time to failure.
Results
The study included 133 Trifecta, 156 Epic, and 321 Magna Ease valves. Seventy‐six percent (1941/2551) of patients had to be excluded due to insufficient echo data. Through univariate analysis, 34% (216/610) of valves met deterioration criteria after 24 months. Unadjusted survival curves showed a significant difference between valves (p ≤ .001), with a longer mean time to deterioration for the Magna Ease versus Trifecta and Epic of 68.9 versus 50.1 and 38.2 months, respectively. A Cox proportional hazard analysis found worse hazard ratios of 1.69 (p ≤ .04) and 2.4 (p ≤ .01) for Trifecta versus Magna and Epic versus Trifecta, respectively.
Conclusion
All three valve types demonstrated structural valve deterioration on echocardiographic follow‐up with significant differences in rate. The Magna Ease appeared to have the highest durability, and the Epic the lowest. Further investigation is warranted to confirm the results in a larger multicenter study.
in 2pts and zone 3 in 4 pts. One patient died perioperatively (6%) of ongoing mesenteric ischemia. No patient showed recurrent thromboembolism. One pt required TEVAR explant one month postoperatively for device infection. Five-year survival was 78% with two late nonvascular deaths (lung neoplasia and complication from Crohn disease). A thrombophilia syndrome or neoplasia was diagnosed in 9/17 (52.9%) pre or postoperatively. CONCLUSION: Thoracic FFAT is rare and can involve any aortic segment. Thrombus size and location are key to establish the operative strategy. TEVAR seems a safe alternative to a standard open surgery in presence of adequate proximal and distal landing sites. Freedom from late FFAT recurrence is excellent regardless of the surgical approach. Postoperative thrombophilia and cancer screening is mandatory.
