Ngaba Iindleko zokuSebenza koMhlaza we-CT wokuHlola uMhlaza kuyabonakala?

I-National Lung Screening Trial (NLST) idatha ibonisa ukuba i-computed tomography (CT) i-scans inokunciphisa ukufa komhlaza wemiphunga ngama-20 ekhulwini xa kuthelekiswa ne-X-ray yesifuba. Uphononongo olutsha lwedatha lubonisa ukuba lunokuba luncedo kwezoqoqosho.

Ngokwembali, izigulane zokuhlolwa komhlaza wemiphunga zenziwe ngeX-reyi yesifuba, indlela enexabiso eliphantsi lokuxilongwa. Ezi X-reyi zidutyulwa esifubeni, nto leyo ebangela ukuba lonke ulwakhiwo lwesifuba lubekwe phezulu kumfanekiso wokugqibela we-2D. Nangona i-X-rays yesifuba inemisebenzi emininzi, ngokutsho koshicilelo lwamva nje oluvela kwiYunivesithi yaseBrown, uphando oluphambili olwenziwe kwiminyaka emine edlulileyo, i-NLST, lubonise ukuba i-X-rays ayisebenzi ngokupheleleyo ekuhlolweni komhlaza.

Ukongezelela ekuboniseni ukungasebenzi kwe-X-rays, i-NLST ibonise ukuba ukufa kwancitshiswa malunga neepesenti ze-20 xa i-dose ephantsi ye-spiral CT scans isetyenziswe. Injongo yohlalutyo olutsha, olwenziwa yi-epidemiologists kwiYunivesithi yaseBrown, kukufumanisa ukuba ii-CT scans eziqhelekileyo - ezixabisa kakhulu kune-X-rays - zinengqiqo kwinkqubo yokunakekelwa kwempilo, ngokutsho kweendaba.

Imibuzo enjalo ibalulekile kwimeko yezempilo yanamhlanje, apho iindleko zokwenza i-CT scans rhoqo kwizigulane zingenakunceda inkqubo yonke.

"Ngokonyukayo, iindleko ziyinto ebaluleke kakhulu, kwaye ukwaba imali kwindawo enye kuthetha ukuncama abanye," utshilo u-Ilana Gareen, unjingalwazi oncedisayo kwi-epidemiology kwiYunivesithi yaseBrown yeSikolo seMpilo yoLuntu, kwingxelo yeendaba.

Uphononongo olupapashwe kwiNew England Journal of Medicine lubonise ukuba idosi ephantsi yokuhlolwa kwe-CT ixabisa malunga ne-$1,631 ngomntu ngamnye. Iqela libale imilinganiselo eyongeziweyo yeendleko zokusebenza kakuhle (ICERs) ngokusekelwe kwiingcamango ezahlukeneyo, okubangele i-ICERs ye-52,000 ye-$ 52,000 ngonyaka wobomi obufunyenweyo kunye ne-$ 81,000 ngonyaka wobomi obuhlengahlengisiweyo (QALY) obufunyenweyo. I-akhawunti ye-QALY yomahluko phakathi kokuhlala kwimpilo enhle kunye nokuhlala kunye nemicimbi ebalulekileyo yezempilo, njengoko kuchazwe kwi-press release.

I-ICER yimetric entsonkothileyo, kodwa umgaqo wesithupha kukuba nayiphi na iprojekthi engaphantsi kwe-100,000 yeedola kufuneka ithathelwe ingqalelo njengeendleko. Nangona ezi ziphumo zithembisa, izibalo zisekelwe kwinani leengqikelelo ezichaphazela kakhulu iziphumo. Ngoku engqondweni, isiphelo esiphambili sophononongo sesokuba impumelelo yezemali yezo nkqubo zokuhlola iya kuxhomekeka kwindlela eziphunyezwa ngayo.

Ngelixa ukwenza umfanekiso womhlaza wemiphunga usebenzisa i-CT scans isebenza ngakumbi kunokusebenzisa ii-X-reyi, uphando lusaqhubeka ukuze kuphuculwe ngakumbi i-CT scan. Kutshanje, inqaku elipapashwe kwi-Med Device Online lixoxe ngesoftware yokucinga enokunceda ukuphucula ukubonwa kwamaqhuqhuva emiphungeni.
