Sejumlah penelitian telah mengaitkan penurunan fungsi kognitif dengan kepatuhan minum obat. Diabetes Melitus Tipe 2 (DMT2) merupakan salah satu faktor resiko dari penurunan fungsi kognitif yang jarang disadari pasien. Oleh karena itu, penulis mencoba menilai pengaruh penurunan fungsi kognitif terhadap kepatuhan minum obat pada pasien DMT2. Penelitian ini menggunakan desain potong lintang yang dilakukan di Puskesmas Pasar Minggu Jakarta. Fungsi kognitif dinilai dengan kuesioner Montreal Cognitive Assesment versi Indonesia (MoCA-Ina) yang telah divalidasi. Penilaian kepatuhan dilakukan menggunakan kuesioner Adherence to Refills and Medications Scale (ARMS) versi bahasa Indonesia yang tervalidasi dan Pharmacy refill adherence yaitu dengan menghitung Proportion of Days Covered (PDC). Pasien dikatakan patuh jika skor ARMS <12 dan hasil perhitungan PDC ≥80%. Hasil penelitian ini menunjukkan bahwa penurunan fungsi kognitif berhubungan dengan kepatuhan minum obat yang buruk (p=0,005). Berdasarkan analisis multivariat, pasien dengan fungsi kognitif menurun 3,7 kali menyebabkan ketidakpatuhan minum obat dibanding pasien dengan fungsi kognitif normal setelah dikontrol variabel usia, tingkat pendidikan, kadar HbA1c, dan komorbid dislipidemia.

Several studies have linked cognitive decline with lack of adherence to medication. Type 2 Diabetes mellitus (T2DM) is one of the risk factors for cognitive decline that patients are rarely aware of. Therefore, the aim of this study is to assess the effect of decreased cognitive function on medication adherence in T2DM patients. The study uses a cross-sectional design and was conducted at the Pasar Minggu Primary Health Center, Jakarta, Indonesia. Cognitive function was assessed using a validated Indonesian version of the Montreal Cognitive Assessment (MoCA-Ina) questionnaire. Adherence assessment was made using a validated Indonesian version of the Adherence to Refills and Medications Scale (ARMS) questionnaire and the proportion of days covered (PDC). A patient was considered to be adhere if the ARMS score was <12 and the PDC calculation result was ≥80%. The results of this study showed that cognitive decline was associated with poor medication adherence (p=0.005). Based on multivariate analysis, patients with cognitive decline had 3.7 times greater nonadherence to medication than patients with normal cognitive function after controlling for variables of age, education level, HbA1c levels, and comorbid dyslipidemia.
