ContextConcerns regarding the applicability of “special follow up” schemes the early introduction of technologies that are deemed to have an important It can hamper impact on health. In some cases the new technology has already diffused within the health system and patients who are candidates for the procedure can be discriminated from receiving it if they do not attend the authorized centers. Research studies are frequently very demanding (too many variables, follow up visits, long follow up times) and clinicians allege that they have great difficulty in collaborating (lack of time, important workload that difficults data collection, patient losses). The process is very lengthy and medical procedures frequently evolve during the research process, to the point that indications might be obsolete or the trials findings might be of little relevance when results are available. Does not provide useful information to resolve uncertainties regarding appropiate use in daily practice and best clinical management.

Main considerations derived from the guidelineOnly key data should be collected (MINIMUM DATA SET )The different stakeholders should be implicated from the beginning and should be involved in theestablishement of data requirements, data collection methods, follow up schedule and outcomeindicators that are considered feasible, clinically meaningfull and relevant to the health caresystemData recorded should be as far as possible, final result variables and be part of data recordedroutinelly in medical records or considered relevant for decision makingThe study should not increase the number of procedures or tests performed to the patientWhenever possible, follow up contacts should be in agreement with routine check upsThe follow up should be as short as possible, even though sufficient for obtaining an adequatenumber of patients in each study subgroupData collection instruments should be context specific. The incorporation of outcome variables into theelectronic clinical records is the recommended option but not always feasible.

Results of post-introduction observation of TAVIsVía de acceso Type of access n= 48 n= 33 94 TAVI implantations 6 follow up losses All symptomatic patients with n= 14 high surgical risk or inoperable
Results of post-introduction observation of TAVIs Mean age: 82 years (64-93) 8,5% < 75 yrs No significant differences among hospitals
Results of post-introduction observation of TAVIs Logistic EuroScore: 15,1% (2,9-73,2)
R esults of post-introduction observation ofTAVIs Correct implantation: 96,8% Hospital mortality: 7,4% Acumulated 1 year survival: 81,7% Complications: 40,4 % All patients improved NYHA functional class
Proposal derived from the stakeholder meeting Update of systematic review and creation of a multidisciplinar group for the revision of selection criteria for TAVI authorization Policy makers Representatives from authorized centres Creation of a multidisciplinary Hospital Commission within each authorized hospital to consensuate TAVI implantation Cardiologists and cardiac surgeons Analise implantation variability not attributed to geographical differences (accessibility problems, overuse, underuse?)
Main limitations Delay in the forwarding of data (various contacts and active collection in 1 centre) Different follow up visits and data recording times Not all patients underwent transthoracic echocardiography before or after the intervention and so it was impossible to assess valve hemodynamics, paravalvular leaks or severity of aortic stenosis The majority of centres only took into account disnea to establish symptomatology Insufficient number of patients to determine if there are deviations in adverse events (n.s) or if there are differences between different subgroups (type of access, type of valve, hospital, etc) Insufficient patients to detect cost deviations Reticence of clinicians to be evaluated by external organizations
Ongoing strategies to improve applicability Definition and standardization of result variables to homogeneize data recording Development of a web application to promote visibility and use of the tool in collaborative projects in order to increase power to detect deviations in effectiveness/safety and allow for subgroup analysis NEAR FUTURE!!! Incorporate result variables in electronic clinical records and develop linkage mechanism to import data
