Purpose: The rapid response team is a patient safety system that detects symptoms and signs of deteriorating inpatients and provides intervention and treatment. This study analyzed the factors influencing the activation time of the team. Methods: This is a descriptive correlation study that analyzed the electronic medical records of patients activated by the rapid response team. The collection period was from January 2014 to December 2017. We analyzed 278 pieces of data activated by the rapid response team for patients aged 16 years or older at C University S Hospital in Seoul. We employed the SPSS 23.0 program for data analysis. Results: The reasons for activation of the rapid response team were oxygen saturation of less than 90.0%, other causes, and change in consciousness. The most common diagnosis of activated patients was respiratory failure (32.4%). The average activation time was 153.43±286.05 min. The activation time was shortest during convulsions (13.29±7.32 min). For patients with a history of kidney disease (B=0.58, p=.008), in case of surgery (B=0.55, p<.001), if the first symptom is mediated by the physician (B=0.53, p=.007) the active time is often extended. On the other hand, activation time is reduced when consciousness changes (B=-0.51, p=.002), especially when oxygen saturation is below 90.0% (B=-0.64, p<.001). Conclusion: Based on the results of the study, it is expected that patients deteriorating in the general ward would be recognized early, which will help in the effective activation of the rapid response team.

Purpose: The purpose of this study was to investigate the motor subtypes of delirium in patients in a Surgical Intensive Care Unit (SICU), and identify the factors related to the characteristics of patients according to the motor subtypes of delirium. Methods: Data were collected in the SICU of a tertiary hospital in ^⁎ city from October 2018 to June 2019. Delirium was detected using the Confusion Assessment Method for the ICU (CAM-ICU) and motor subtypes of delirium were measured with the Delirium Motor Subtype Scale (DMSS)-4. Patients' characteristics were obtained by using the electronic medical records. Descriptive statistics were used to analyze the data. Results: Among 1,112 patients, 172 patients showed delirium (15.5%). After excluding dementia patients and patients refusing to participate in the study, 126 patients included in the final analysis. Delirium patients were classified as hyperactive delirium (32.5%), hypoactive delirium (42.9%), mixed delirium (11.9%), and non-motor subtype delirium (12.7%). Conclusion: The study results suggest that hypoactive delirium is the most prevalent motor subtype of delirium in SICU. More application of ventilators, more administration of sedatives, more use of catheters, and higher nursing severity were reported for hypoactive delirium cases than hyperactive ones. Therefore, it is necessary to assess early the motor subtypes of delirium using structured tools and develop appropriate nursing interventions suitable for each subtype of delirium.

Background: Patients diagnosed with cancer tend to have multiple risk factors for drug related problems such as old age, comorbid conditions, self-medication, additional medications for supportive therapy, and the cancer treatment itself. Objective: The aim of this study was to investigate notable polypharmacy and related problems in oncology patients during hospitalization or following clinic visit. Method: The electronic medical records of patients who were discharged from oncology division at Seoul National University Hospital (SNUH) from June $1^{st}$ to June $30^{th}$, 2011 were retrospectively reviewed. Results: A total of 334 discharged patients were included in this study. Among them, 221 patients had pre-admission medications. Forty percent of the patients, including 60.3% of elderly patients (over 65 years of age) were prescribed more than 5 kinds of medications. Twenty percent of the patients were prescribed to take medications more than 7 times a day. Medication duplications were observed in 2.4% of patients. In 10.5% of the reviewed patients, 47 cases of potential drug-drug interaction including 3 cases of contraindication and 17 cases of major clinical implication according to Micromedex were detected. Medication changes were made in 88% of patients during hospitalization and in 94.7% of patients at their first visit after discharge. Antidiarrheal agent (loperamide) was prescribed along with laxatives in 18.5% of the prescriptions and inadequate instructions on how to take it were observed in 63% of the prescriptions. Conclusion: This study identified the prevalence of polypharmacy and related problems in cancer patients, which presents the need for an active role of pharmacists in pharmaceutical care in oncology wards.

Background: Invasive aspergillosis (IA) is associated with high morbidity and mortality, particularly among immunocompromised patients, such as lung transplant recipients. Voriconazole, the first-line therapy for IA, shows a non-linear pharmacokinetic profile and has a narrow therapeutic range. Careful and appropriate administration is necessary, primarily because it is used for critically ill patients; however, the clinical usefulness of therapeutic drug monitoring (TDM) has not been sufficiently verified. Therefore, in this study, we validated the safety and efficacy of voriconazole TDM in lung transplant recipients receiving only voriconazole for IA treatment. Methods: The electronic medical records of lung transplant recipients (${\geq}19$ years of age) administered only voriconazole for > 7 days for treatment of IA from June 1, 2013 to May 31, 2018 were analyzed retrospectively. Results: Among the 54 patients, 27 each were allocated to TDM and non-TDM groups, respectively. There were no significant differences in patient characteristics between the two groups except for ICU-hospitalization status. Of the TDM group patients, 81.5% needed adjustment of voriconazole dosage because the levels were out of target range. Comparison of two groups showed that treatment response was higher throughout treatment and switching rates of second-line agents were significantly lower in the TDM group, but it was insufficient to confirm safety improvements through voriconazole TDM. Conclusions: Considering that the treatment response tended to be higher and the rates of switching to second-line antifungal agents were lower in the TDM group, voriconazole TDM may increase the therapeutic effect on IA in lung transplant patients.

Background: Hypercalcemia is an important metabolic emergency condition in cancer patients. Bisphosphonate is the treatment of choice for hypercalcemia, whereas calcitonin and hydration with furosemide are recommended for acute supportive therapy. However, data regarding real-world treatment patterns and outcomes of pharmacological treatments are limited. Therefore, we aimed to investigate the treatment patterns and clinical outcomes of hypercalcemia treatment in solid tumor patients. Methods: Electronic medical records of 123 adults with solid cancers and albumin-corrected calcium levels >10.5 mg/dL or ionized calcium levels >1.35 mmol/L were reviewed. We retrospectively analyzed the pharmacological treatment and recovery rate according to the severity of hypercalcemia. Results: A total of 177 cases were identified, of which 49 were not treated and 30 were treated with hydration only. In moderate-to-severe cases, 86.5% received pharmacological treatment. Thirty-four cases (19.2%) were treated with bisphosphonate alone and 58 cases (32.8%) were treated with bisphosphonate and calcitonin. In mild hypercalcemia cases, the recovery rate was higher for those receiving hydration only or pharmacological treatment (79.7%) than for those receiving no treatment (61.4%, p = 0.041). Most moderate-to-severe cases were treated with medication and of those treated, 56.3% recovered. The recovery rate was lower in those treated with bisphosphonate alone (38.2%) than in those who underwent calcitonin combination treatment (73.7%, p = 0.001). Conclusions: Bisphosphonate combined with calcitonin was found to be more effective than bisphosphonate alone for the treatment of moderate-to-severe hypercalcemia. Considering the current shortage of calcitonin, further efforts are required to ensure its stable supply.

Background: The role of clinical pharmacists in medication therapy to improve clinical and economic outcomes has been reported in the literature. This study was conducted to analyze the changes in details of medication interventions before and after the introduction of clinical pharmacists into the care of neurocritical care unit (NCU) patients, and to evaluate the economic effects of clinical pharmacists by calculating the avoidance cost. Methods: A retrospective study was conducted reviewing the electronic medical records from June 2013 to May 2014 (before), and from June 2016 to May 2017 (after). We calculated the number and rates of intervention, the acceptance rates of it, and also reviewed the list of interventions. We calculated avoidance cost if there was no intervention. Results: The monthly mean number of interventions increased from 8.0 (${\pm}5.7$) to 31.7 (${\pm}12.8$) (P<0.001) and the frequency of intervention also increased from 0.8% to 1.6% (P=0.003). The most frequently provided pharmacist intervention was nutritional support before introduction of clinical pharmacists and discussions on the medication plan after. The number of classified interventions was 14 before introduction of clinical pharmacist services and 33 after. The calculated cost avoidance associated with a clinical pharmacists' integration was 77,990,615 won per year. Conclusion: Introduction of clinicals pharmacist into the NCU was associated with increased intervention rates and expanded types of clinical interventions. The cost avoidance achieved by the pharmacists' interventions can be further explored to evaluate if similar expansions of pharmacists' services achieve similar results in other settings.

Objectives: This retrospective study aimed to analyze data on nerve damage in patients who complained of sensory changes after dental implant surgery, the clinical results according to proximity of the implant fixture to the inferior alveolar nerve (IAN) canal, and the factors affecting recovery of sensation. Materials and Methods: The electronic medical records of 64 patients who had experienced sensory change after implant surgery were reviewed. Patients were classified by sex, age, implant installation sites, recovery rate and the distance between the implant fixture and IAN canal on computed tomography (CT). The distance was classified into Group I (D>2 mm), Group II (2 mm≥D>0 mm), and Group III (D≤0 mm). Results: The 64 patients were included and the mean age was 57.3±7.3 years. Among the 36 patients who visited our clinic more than two times, 21 patients (58.3%) reported improvement in sensation, 13 patients (36.1%) had no change in sensation, and 2 patients (5.6%) reported worsening sensation. In Group II, symptom improvement was achieved in all patients regardless of the removal of the implant fixture. In Group III, 8 patients (40.0%) had reported symptom improvement with removal of the implant fixture, and 2 patients (33.3%) of recovered patients showed improvement without removal. Removal of the implant fixture in Group III did not result in any significant difference in recovery (P=0.337), although there was a higher possibility of improvement in sensation in removal cases. Conclusion: Clinicians first should consider removing the fixture when it directly invades the IAN canal. However, in cases of sensory change after dental implant surgery where the drill or implant fixture did not invade the IAN canal, other indirect factors such as flap elevation and damage due to anesthesia should be considered as causes of sensory change. Removal of the implant should be considered with caution in these situations.

Background: Denosumab (Prolia®) is administered every 6 months for osteoporosis treatment. Co-administration of calcium and vitamin D is required to minimize hypocalcemia risk. We evaluated clinical outcomes based on the administration interval of denosumab and co-prescription with calcium-vitamin D combination products. Methods: A retrospective study was conducted using electronic medical records from 668 patients who started denosumab therapy between January 1 and December 31, 2018, at Seoul National University Bundang Hospital. Clinical outcomes, as measured by changes in T-score, were evaluated by the intervals and concurrent prescriptions with calcium-vitamin D combination products. Results: Of the 668 patients, 333 patients met the eligibility criteria. These patients were divided into two groups based on appropriateness of the administration interval: "Appropriate" (304 patients, 91.3%) and "Inappropriate" (29 patients, 8.3%). T-score changes were significantly higher in the "Appropriate" than in the "Inappropriate" group (0.30±0.44 vs. 0.13±0.37, p=0.048). At the beginning of the treatment, 221 patients (66.4%) were prescribed calcium-vitamin D combination products, but the changes in T-scores were not significantly different by the prescription status of the product (0.29±0.46 vs. 0.28±0.38, p=0.919). Conclusion: T-scores were significantly improved in patients with appropriate administration intervals. No significant changes in T-scores were observed by the prescription status with calcium-vitamin D combination products. For optimal treatment outcomes, prescribers should encourage adherence to the approved prescription information on dosage and administration, and pharmacists should provide medication counseling for patients.
