ABSTRAK
Latar Belakang: Malnutrisi berdampak besar pada pasien kanker sehingga harusdievaluasi dengan Patient-Generated Subjective Global Assessment (PG-SGA),namun memakan waktu dan membutuhkan tenaga kesehatan terlatih. Pengukurankekuatan genggam tangan (KGT) memiliki keuntungan lebih singkat dan mudahdibandingkan PG-SGA, tetapi belum ada data titik potong dan akurasi diagnostikKGT pada pasien kanker di Indonesia. Tujuan: Mendapatkan titik potong dan akurasi diagnostik KGT sebagai penapismalnutrisi pasien kanker rawat jalan di RSCM.Metode: Penelitian potong lintang ini dilakukan pada pasien 18-59 tahun dipoliklinik onkologi RSCM selama 4 Mei-1 Oktober 2015. Titik potong KGTdianalisis menggunakan kurva ROC. Akurasi diagnostik KGT dinilai denganmenghitung sensitivitas, spesifisitas, NDP, NDN, RKP, dan RKN.Hasil: Proporsi pasien dengan status nutrisi baik, malnutrisi sedang, danmalnutrisi berat adalah17,4%, 64,2%, dan 18,4%. Titik potong optimal KGT pasien kanker lelaki dan perempuan berturut-turut adalah ≤ 36,5 dan ≤ 21,5 kgfdengan sensitivitas 92,2% dan 73,9%, spesifisitas 54,6% dan 60,9%, NDP 92,2% dan 88,3%, NDN 54,6% dan 36,8%, RKP 2 dan 1,9, serta RKN 0,1 dan 0,4. Simpulan: Titik potong optimal KGT pasien kanker lelaki dan perempuanberturut-turut adalah ≤ 36,5 dan ≤ 21,5 kgf. Akurasi diagnostik KGT pasienkanker lelaki dan perempuan sebagai penapis malnutrisi berturut-turut dinilai baik dan sedang.ABSTRACT
Background: Malnutrition has a huge impact on cancer patients and therefore ithas to be evaluated using PG-SGA, but there are limitations such as the timeconsumingnature and the need of trained health personnels. Measurement ofHGS is faster and easier, but there is no sufficient information regarding its cutoffpointand diagnosticaccuracyfor cancerpatientsin Indonesia.Aim:defining cut-off point and diagnostic accuracy of HGS as a malnutritionscreening modality for outpatient cancer population at RSCM.Method: A cross-sectional study was conducted at RSCM oncology outpatientclinic from May 4th-October 1st, 2015. Subjects were 18-59 years old. Cut-offpoint and diagnostic accuracy of HGS were analyzed to generate sensitivity,specificity, PPV, NPV, LR+, and LR- .Result: The proportion of well nourished, moderately malnourished, and severelymalnourished subjects were 17.4%, 64.2%, and 18.4%, respectively. The optimalHGS cut-off point in male and female cancer patients were ≤ 36.5 and ≤ 21.5 kgfrespectively with sensitivity 92.2% and 73.9%, specificity 54.6% and 60.9%,, PPV92.2% and 88.3%, NPV 54.6% and 36.8%, LR+ 2 and 1.9, and LR- 0.1 and 0.4. Conclusion: The optimal HGS cut-off point in male and female cancer patientswere ≤ 36.5 and ≤ 21.5 kgf, respectively. Diagnostic accuracy of HGS as amalnutrition screening modality in male and female cancer patients were good and moderately good.;Background: Malnutrition has a huge impact on cancer patients and therefore ithas to be evaluated using PG-SGA, but there are limitations such as the timeconsumingnature and the need of trained health personnels.
