AbstractA delirium in patients in the intensive care unit (ICU) is a manifestation of a severe acute dysfunction of the brain. It has a high prevalence and is associated with a relevant increase in morbidity and mortality. A cholinergic deficit and dopaminergic overactivity are considered to be a cause of delirium. Polypharmacy, which is often present before admission to the ICU, especially in the elderly, plays a key role as a trigger. The knowledge and identification of risk factors for delirium is a precondition for the early and effective prevention of delirium. The aim is the pre-operative or pre-interventional optimization of modifiable risk factors. Early and effective prevention of delirium can improve clinical outcome, reduce mortality, and positively impact long-term functional outcome. Non-pharmacological measures are always the basis for the prevention of delirium: maintenance of the day-night rhythm, sleep promotion at night and stimulation during the day, involvement of relatives, the avoidance of dehydration and malnutrition, and others more. They are pharmacologically accompanied by an effective analgesia and a target and symptom-oriented sedation with well controllable, as little as possible delirogenic substances. Interdisciplinary and interprofessional cooperation is essential so that preventive concepts significantly reduce the risk of delirium, even in high-risk patients.

Pendahuluan. Infeksi masih merupakan ancaman yang serius bagi dunia kesehatan saat ini, terutama bagi populasi khusus seperti usia lanjut. Usia dinyatakan sebagai salah satu faktor prediktor dalam keberhasilan vaksinasi. Semakin tua usia seseorang, respon imunnya akan semakin buruk. Respon yang berbeda pada usia lanjut ini diperkirakan karena frailty dan kejadian immunosenescense yang mendasarinya. Penelitian ini dilakukan untuk mengetahui hubungan status frailty dengan respon imun pascavaksinasi influenza pada populasi usia lanjut.Metode. Studi kohort retrospektif ini mengambil data dari penelitian induk dengan subjek usia lanjut berusia ≥60 yang tergabung dalam Posyandu Lansia di 4 kelurahan di Kecamatan Pulo Gadung, Jakarta Timur. Status frailty ditentukan berdasarkan kuisoner Frailty Index 40 Items (FI-40). Vaksin Influenza yang dievaluasi adalah vaksin influenza trivalen inaktif. Serokonversi didefinisikan sebagai peningkatan titer inhibisi hemagglutinin sebanyak 4x lipat. Seroproteksi didefinisikan sebagai titer inhibisi hemagglutinin ≥1:40.Hasil. Terdapat 140 subjek penelitian. Tingkat serokonversi vaksin influenza pada kelompok frail, pre-frail dan sehat adalah 37,9%, 39% dan 60%. Tingkat seroproteksi vaksin influenza pada kelompok frail, pre-frail dan sehat adalah 80%, 92,2% dan 94,8% . Risiko relatif (RR) kelompok pre-frail/frail untuk kejadian tidak serokonversi adalah 0,93 (IK 95% 0,72-1,02) dan RR untuk kejadian tidak seroproteksi adalah 1,7 ( IK 95% 0,5-6,2).Simpulan. Tidak ditemukan hubungan antara status frailty dengan serokonversi dan seroproteksi vaksin influenza pada populasi usia lanjut.Kata Kunci: Frailty, pre-frail, frail, serokonversi, seroproteksi, usia lanjut, vaksin influenza  Correlation of Frailty Status with Influenza Vaccine Seroconversion and Seroprotection among Elderly PopulationIntroduction. Infection is still considered as a serious health threat in the world, especially among the elderly. Age was identified as one of the predictor factors for successfull vaccination. Immune response would decrease in older people. A different response in the elderly is expected from frailty and underlying immunosenescense events. This study was conducted to determine the relationship with the Frailty status after the vaccination immune response of influenza in the elderly population. Methods. This retrospective cohort study was conducted using secondary data from the parent study of elderly subjects age ≥60 years who live in the community of Posyandu lansia in Pulo Gadung Region, East Jakarta. Frailty status was stated by Frailty Index 40 Items (FI-40). The influenza vaccine evaluated was the Trivalent Inactivated Vaccine. Seroconversion defined as four fold increase hemagglutinin inhibition titre. Seroprotection defined as Hemagglutinin Inhibition titer ≥1:40. Results. There are 140 subject included in this study. Seroconversion influenza vaccine rate in frail, pre-frail, and robust group are 37.9%, 39%, 60%, respectively. Seroprotection rate in frail, pre-frail, and robust group are 80%, 92.2%, 94.8%, respectively. Relative Risk (RR) pre-frail/frail group for not seroconverted is 0.93 (CI 95% 0.72-1.02), and RR for not seroprotected is 1,7 ( CI 95% 0.5-6.2). Conclussions. There is no association between frailty status and seroconversion nor seroprotection of influenza vaccine in elderly population. Keywords: elderly, frail, influenza vaccine, pre-frail, seroconversion, seroprotection
