Make SQL query faster that it is

Question

I have the below query that it works fine but it takes time. And the table is being bigger and bigger so it takes more and more time. Is there any way to make this query faster? The query is here:

SELECT        patient.bartar_id, patient.bartar_enteringthesystem, patient.bartar_proviencename, patient.bartar_cityname, patient.bartar_coloplastrepname, patient.bartar_consultorname, 
                     patient.bartar_provienceofsurgeryname, patient.bartar_cityofsurgeryname, patient.bartar_surgeryhospitalname, patient.bartar_doctorsname, patient.bartar_patientstatusname, patient.bartar_ostomytypename, 
                     patient.bartar_insurancetypename, patient.bartar_ostomytimename, patient.bartar_dateofseurgery, patient.bartar_deathhealeddate, patient.bartar_customercode, patient.bartar_name, patient.bartar_family, 
                     patient.bartar_age, patient.bartar_birthyear, patient.bartar_connectornursename, patient.bartar_hastakmiliname, patient.bartar_doctorsname AS Expr1, patient.bartar_patientstatusname AS Expr2, 
                     patient.bartar_generalstatusname, patient.new_description AS CCDesc, patient.bartar_visitname, patient.bartar_repvisitname, patient.bartar_salename, patient.bartar_customersstatusname, r.bartar_date, 
                     r.bartar_delay, r.bartar_nextcall, r.new_newcaller, r.bartar_bagPerMonth, r.bartar_brand, r.bartar_paste, r.bartar_bag, r.bartar_acc, r.bartar_insuranceinfo, r.bartar_pastePerMonth
FROM            Filteredbartar_newpaitient AS patient INNER JOIN

and the rest is here:

(SELECT DISTINCT bartar_patientname,
(SELECT        TOP (1) bartar_date

ORDER BY patient.bartar_enteringthesystem ASC

Answer 1

Get rid of all the top 1 sub
just join or left join

min(bartar_date)... 
from   
group by bartar_patientname
