Ngaba Uvavanyo lwe-CT lomhlaza wemiphunga lusebenza kakuhle?

Idatha yeNational Lung Screening Trial (NLST) ibonisa ukuba ii-computed tomography (CT) scans zinokunciphisa ukufa kwabantu abanomhlaza wemiphunga ngama-20 ekhulwini xa kuthelekiswa nee-X-ray zesifuba. Uvavanyo olutsha lwedatha lubonisa ukuba inokuba luncedo kwezoqoqosho.

Ngokwembali, izigulane ezihlola umhlaza wemiphunga ziye zenziwa nge-X-ray yesifuba, indlela yokuxilonga engabizi kakhulu. Ezi X-ray zidutyulwa esifubeni, nto leyo ebangela ukuba lonke ulwakhiwo lwesifuba lubekwe kumfanekiso wokugqibela we-2D. Nangona iiX-ray zesifuba zisetyenziswa kakhulu, ngokutsho kwengxelo yakutshanje evela kwiYunivesithi yaseBrown, uphando olukhulu olwenziwe kwiminyaka emine eyadlulayo, i-NLST, ibonise ukuba iiX-ray azisebenzi ngokupheleleyo ekuxilongeni umhlaza.

Ukongeza ekuboniseni ukungasebenzi kakuhle kwe-X-rays, i-NLST ikwabonise ukuba ukufa kwehle ngama-20 ekhulwini xa kusetyenziswa ii-CT scans ezijikelezayo ezinedosi ephantsi. Injongo yolu hlalutyo lutsha, olwenziwe ziingcali zezifo eBrown University, kukufumanisa ukuba ngaba ii-CT scans eziqhelekileyo - ezibiza kakhulu kunee-X-rays - zinengqondo na kwinkqubo yokhathalelo lwempilo, ngokutsho kwengxelo yabezindaba.

Imibuzo enjalo ibalulekile kwimeko-bume yezempilo yanamhlanje, apho iindleko zokwenza ii-CT scans rhoqo kwizigulana zisenokungayincedi inkqubo iyonke.

“Ixabiso liyanda, kwaye ukwabela imali kwenye indawo kuthetha ukuncama eminye,” utshilo uIlana Gareen, uprofesa oncedisayo we-epidemiology kwiSikolo sezeMpilo kaRhulumente kwiYunivesithi yaseBrown, kwingxelo yabezindaba.

Uphononongo olupapashwe kwiNew England Journal of Medicine luveze ukuba ukuhlolwa kwe-CT ngedosi ephantsi kubiza malunga ne-$1,631 ngomntu ngamnye. Iqela libalile umlinganiselo wokusebenza kakuhle kweendleko (ii-ICER) ngokusekelwe kwiingqikelelo ezahlukeneyo, nto leyo ebangele ukuba ii-ICER zibe yi-$52,000 ngobomi bomntu ngamnye ezifunyenweyo kunye ne-$81,000 ngobomi bomntu ngamnye obulungisiweyo ngomgangatho (ii-QALY). Ii-QALY zichaza umahluko phakathi kokuphila impilo entle nokusinda ngeengxaki zempilo ezibalulekileyo, njengoko kuchaziwe kwingxelo yabezindaba.

I-ICER yindlela entsonkothileyo yokulinganisa, kodwa umthetho oyintloko kukuba nayiphi na iprojekthi engaphantsi kwe-$100,000 kufuneka ithathwe njengenexabiso eliphantsi. Nangona ezi ziphumo zithembisa, izibalo zisekelwe kwiingqikelelo ezininzi ezichaphazela kakhulu iziphumo. Ngokuphathelele oku engqondweni, isigqibo esiphambili sophando kukuba impumelelo yezemali yeenkqubo zokuhlola ezinjalo iya kuxhomekeka kwindlela eziphunyezwa ngayo.

Nangona ukufota umhlaza wemiphunga usebenzisa ii-CT scans kusebenza ngcono kunokusebenzisa ii-X-reyi, uphando luyaqhubeka ukuphucula ii-CT scans. Kutshanje, inqaku elipapashwe kwi-Med Device Online lithethe ngesoftware yokufota enokunceda ekufumaneni amaqhuqhuva emiphungeni.
