Öğe Evaluation of clinical pharmacist interventions on drug-related problems in the gastroenterology ward(Marmara University, 2022) Ceylan, Cengizhan; Sancar, Mesut; Beceren, Ayfer; Demir, Ali; Kuş, Coşkun; Omurtağ, Gülden ZehraIntegrating clinical pharmacists in a multidisciplinary patient care team improves the treatment process by identifying and resolving drug-related problems (DRPs). The aim of the study was to determine the effect of clinical pharmacist intervention for DRPs in the gastroenterology service. The first period of the study was conducted between 15.06.2018 and 15.02.2019. Eighty patients admitted to the gastroenterology ward, who used at least one medication, were included in ‘the study group’. The clinical pharmacist participated in ward rounds and made interventions to solve identified DRPs. In the second period of the study, the control group consisted of 80 patients admitted to the same ward between 01.03.2019 and 06.06.2019. DRPs were determined only from the data obtained from the hospital system in the control group. DRPs were classified according to the European Pharmaceutical Care Network (PCNE V9.1). A total of 136 and 46 with an average of 1.7 and 0.57 DRPs per patient (p?0.01) were identified in the study and control groups, respectively. Of the DRPs in the study group, 59 were related to treatment effectiveness, while 61 were related to treatment safety. Likewise, 21 DRPs were related to treatment effectiveness in the control group, while 12 were related to treatment (p?0.01). 65% of the interventions were made at the physician level and 49% at the drug level. 97% (n=133) of the total interventions were accepted. The number of DRPs was significantly reduced in the control group within the time frame after the clinical pharmacist intervention period. In conclusion, clinical pharmacists' importance in detecting and preventing DRPs in the gastroenterology ward has been demonstrated.Öğe Evaluation of clinical pharmacist interventions on drugrelated problems in the gastroenterology ward(Marmara University, 2022) Ceylan, Cengizhan; Sancar, Mesut; Beceren, Ayfer; Demir, Ali; Kuş, Coşkun; Omurtag, Gülden ZehraIntegrating clinical pharmacists in a multidisciplinary patient care team improves the treatment process by identifying and resolving drug-related problems (DRPs).

The fractional derivatives are taken in the sense of Caputo which is more suitable than Riemann-Liouville sense. We assume that the order q satisfy the condition nq = 1 for some natural number n which determines the number of the linearly independent solutions. Since the delay term is small, the linear fractional differential equation is expanded in powers series of which reduce the problem to regular or singular perturbation problem for which it is easier to find the solution. The solution is obtained in the form of a series expansion of E. To demonstrate the accuracy and the effectiveness of the proposed approach, some illustrative examples are presented.Öğe The stability analysis of a system with two delays(Springeropen, 2018) Erman, Sertaç; Kodal Sevindir, Hülya; Demir, AliThis paper presents new results of stability analysis for a linear system with two delays. We attempt to determine the asymptotic stability regions of the system in a parameter space by using D-partition method. Moreover, some stability and instability conditions in terms of coefficient inequalities have been obtained for the system.
