A double constraint bears on their action: avoiding the risk of dilution of their assistance on the one hand, and finding a satisfying mix between long term but highly uncertain results and short term but often limited to solvency consideration outcomes on the other hand.
Several key areas will be discussed, including selection of patients, trial design, psychological intervention considerations, outcomes and evaluation of results, publication of trial results, and special issues related to pediatric clinical trials.
With respect to technical considerations outcomes of interest were length of the proximal limb, tension on the anastomosis, and anastomotic leakage.
With respect to oncologic considerations outcomes of interest were survival, disease recurrence, and incidence of positive lymph nodes at the root of IMA.
With respect to anatomic considerations outcomes of interest for effect on anastomotic circulation were tissue blood flow, tissue oxygen tension, and anastomotic leakage, and for effect on autonomous innervation were bowel and urogenital dysfunction and location of nerve supply in relation with the root of IMA.
Outcome consideration The effect of the event on the patient is considered.
Last but not least, an important consideration in outcome studies is around multiplicity control for primary endpoints and other secondary endpoints.
At the same time it welcomed the increased consideration of outcome quality in the quality reports and underscored the need to address indicator validity and reliability issues [ 29].
Overall, a consideration of outcome measures, alongside refined methodology as discussed earlier, would allow researchers to assess whether the preliminary indications of benefit seen here can be replicated.
Here, we take full advantage of the richness of the EMR to define cases and controls for select binary traits as well as to extract laboratory values for consideration as outcome variables.
