Ingabe Ukuphumelela Kwezindleko Kokuhlolwa Kwe-CT Umdlavuza Wephaphu Kuyabonakala?

Idatha ye-National Lung Screening Trial (NLST) ibonisa ukuthi izikena ze-computed tomography (CT) zinganciphisa ukufa komdlavuza wamaphaphu ngamaphesenti angu-20 uma kuqhathaniswa ne-X-ray yesifuba. Ukuhlolwa okusha kwedatha kubonisa ukuthi ingase futhi ibe namandla ngokwezomnotho.

Ngokomlando, iziguli ezihlolelwa umdlavuza wamaphaphu zenziwe nge-X-ray yesifuba, indlela engabizi kakhulu yokuxilongwa. Lawa ma-X-ray adutshulwa esifubeni, okwenza ukuthi sonke isakhiwo sesifuba sibekwe phezulu esithombeni sokugcina se-2D. Nakuba i-X-ray yesifuba inokusetshenziswa okuningi, ngokusho kokukhishwa kwabezindaba kwakamuva okuvela e-Brown University, ucwaningo olukhulu olwenziwa eminyakeni emine edlule, i-NLST, lubonise ukuthi ama-X-ray awasebenzi ngokuphelele ekuhlolweni komdlavuza.

Ngaphezu kokubonisa ukungasebenzi kwe-X-rays, i-NLST iphinde yabonisa ukuthi ukufa kwancishiswa cishe ngamaphesenti angu-20 lapho kusetshenziswa ama-CT scans okuvunguza okuphansi. Umgomo wokuhlaziywa okusha, okwenziwa ochwepheshe bezifo eziwumshayabhuqe eNyuvesi yaseBrown, ukuthola ukuthi ukuhlolwa kwe-CT evamile - okubiza kakhulu kune-X-ray - kunengqondo ohlelweni lokunakekelwa kwezempilo, ngokusho kokukhishwa kwabezindaba.

Imibuzo enjalo ibalulekile endaweni yanamuhla yokunakekelwa kwezempilo, lapho izindleko zokwenza ama-CT scan ajwayelekile ezigulini zingase zingazuzisi uhlelo lulonke.

“Ngokwandayo, izindleko ziyisici esibalulekile, futhi ukwaba imali endaweni eyodwa kusho ukudela ezinye,” kuphawula u-Ilana Gareen, umsizi kaprofesa wezifo eziwumshayabhuqe eBrown University's School of Public Health, esitatimendeni.

Ucwaningo olushicilelwe ku-New England Journal of Medicine lwembula ukuthi ukuhlolwa kwe-CT ngedosi ephansi kubiza cishe u-$1,631 umuntu ngamunye. Ithimba libale izilinganiso ezikhuphukayo zokuphumelela kwezindleko (ama-ICER) ngokusekelwe ekucabangeni okuhlukahlukene, okuholele kuma-ICER angu-$52,000 ngonyaka wokuphila ngamunye azuziwe kanye no-$81,000 ngonyaka wokuphila olungiswe ngekhwalithi (QALY) ezuziwe. Ama-QALY alandisa ngomehluko phakathi kokuphila impilo enhle nokuphila ngezinkinga ezibalulekile zempilo, njengoba kushiwo esitatimendeni sabezindaba.

I-ICER iyimethrikhi eyinkimbinkimbi, kodwa umthetho wesithupha uwukuthi noma iyiphi iphrojekthi engaphansi kuka-$100,000 kufanele ibhekwe njengebiza kakhulu. Nakuba le miphumela ithembisa, izibalo zisekelwe enanini lokuqagela okunomthelela kakhulu emiphumeleni. Unalokhu emqondweni, isiphetho esikhulu socwaningo siwukuthi impumelelo yezezimali yalezo zinhlelo zokuhlola izoncika ekutheni zenziwa kanjani.

Nakuba ukucabanga umdlavuza wamaphaphu usebenzisa ama-CT scan kuphumelela kakhulu kunokusebenzisa ama-X-ray, ucwaningo lusaqhubeka ukuze kuthuthukiswe izikena ze-CT. Muva nje, i-athikili eshicilelwe ku-Med Device Online ixoxe ngesofthiwe yokuthwebula engasiza ukuthuthukisa ukutholwa kwamaqhuqhuva wamaphaphu.
