Trying to eliminate duplicate entries when using SQL to build data report

reporting

Trying to pull very detailed information from a large hospital database. Software uses SQL to build a report but repeats entries if multiple tasks are involved.
Example:
Patient XYZ had 2 surgeries on same day. Report will list patient XYZ twice for each surgery. Trying to stop it from listing second time.

New to any type of coding but have been able to get to this point with research.

Below is the current Code we are using (minus private data). Any help would be greately appreciated.

select distinct top 100 percent Rtrim(Ltrim(Patients.FirstName))+space(Len(Patients.MiddleInit))+Rtrim(ltrim(Patients.MiddleInit))+' '+Patients.LastName as Name,
Patients.BirthDate as Birth_Date,
Encounter.EncounterType as Study_Code,
dbo.ConcatReferring(Encounter.EncounterID) as Referring,
dbo.GetLastStudydays(Encounter.PatientID, '', getdate(),'') as Days_since_last_study,
Encounter.EncounterID, Patients.PatientID, Facility.FacilityName as Lab
FROM
Encounter LEFT OUTER JOIN PatientReferral ON (Encounter.EncounterID=PatientReferral.EncounterID)
LEFT OUTER JOIN Personnel Referring ON (Referring.PersonID=PatientReferral.ReferringID) LEFT OUTER JOIN Facility ON (Encounter.EncounterLocation=Facility.FacilityID)
INNER JOIN Patients ON (Patients.PatientID=Encounter.PatientID)
LEFT OUTER JOIN PatientEndPoint ON (Patients.PatientID=PatientEndPoint.PatientID)
WHERE (
dbo.GetLastStudydays(Encounter.PatientID, '', getdate(),'') >= 365 AND
(
Referring.Last_Name = '*' OR
Referring.Last_Name = '*'
) AND
dbo.GetLastStudyresult(Encounter.PatientID, '','') <> 'Negative' AND
NOT (
PatientEndPoint.SurvivalStatus = 'Dead' OR
Patients.BirthDate < '01/01/1925 12:00:00 AM' OR
Encounter.EncounterType like 'SBE%' OR
Encounter.EncounterType like 'SBF%' OR
Encounter.EncounterType like 'SBG%' OR
Encounter.EncounterType like 'SBB%'
) AND
dbo.GetLastStudydays(Encounter.PatientID, '', getdate(),'') < 730
)

ORDER BY Name ASC, Referring ASC
