Studiebefolkning

Pædiatriske patienter i alderen 3 måneder til under 12 år, som kan overvejes for antikoagulering med Pradaxa Pellets på grund af venøse tromboemboliske hændelser (VTE), behandles normalt i neonatologi, pædiatrisk generel kirurgi, hjertekirurgi eller intensivafdelinger. Pædiatriske patienter med antikoagulering med Pradaxa Pellets til forebyggelse af tilbagevendende VTE vurderes normalt af pædiatriske hæmatologer på pædiatriske hæmatologiske afdelinger. Enhver af disse patienter, som får ordineret Pradaxa-pellets, kan overvejes at inkludere i denne undersøgelse.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Cumulative Incidence of Clinically Relevant Bleeding Events
Tidsramme: From first Pradaxa Pellets exposure until its discontinuation plus 3 days of residual effect period, switch to other anticoagulation therapy, or planned observation time, whichever occurred first. Up to 373 days.

Cumulative incidence of clinically relevant bleeding events was reported as the number of participants with clinically relevant bleeding events, defined as the composite of major bleeding events (MBE) and clinically relevant non-major (CRNM) bleeding events, according to recommendations from international thrombosis and hemostasis committees.

MBE were defined as: fatal bleeding; clinically overt bleeding associated with a decrease in hemoglobin of at least 2 grams/deciliter in a 24-hour period; critical site bleeding; bleeding that required an intervention via invasive procedure; and overt bleeding for which a reversal agent was administered.

CRNM bleeding was defined as: overt bleeding for which a blood product was administered and did not meet the criteria for major bleeding; bleeding that resulted in a medical or procedural intervention not meeting major bleeding criteria, including a medication change; and bleeding that resulted in hospitalization or an increased level of care.
From first Pradaxa Pellets exposure until its discontinuation plus 3 days of residual effect period, switch to other anticoagulation therapy, or planned observation time, whichever occurred first. Up to 373 days.
