Purpose: The purpose of this study was to identify the factors influencing medication adherence in hemodialysis patients among primary medical care and secondary medical care. Methods: A cross-sectional survey design was utilized. Data were collected using questionnaires from 280 hemodialysis patients who had taken prescribed medication regularly as a result of chronic renal failure at primary and secondary medical care in Korea. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients, and multiple regression. Results: There were statistically significant differences in medication adherence according to living area (p=.002), health condition (p<.001), amount of medication (p=.004), inconvenience for taking medication (p<.001), and depression level (p=.001). The mean of medication adherence was 3.72 points. Medication adherence was explained by perceived barrier related to medication taking (${\beta}=.338$), attitude (${\beta}=.250$), and depression (${\beta}=.132$). Conclusion: This study strongly recommended that nursing intervention program to improve medication adherence should be developed and a match control study in improvement of medication adherence for hemodialysis patients needs to be done.

Purpose: This study investigates the status of medication use of the elderly with chronic disease taking non-opioid analgesics and attempts to identify factors influencing medication adherence. Methods: Data were collected from September 1 to October 19, 2016. A structured questionnaire was used for face-to-face interview with a convenience sample of 161, elderly people with chronic disease taking non-opioid analgesics. The survey included questions about status of medication use, medication adherence, symptom experience, depression and family function. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression with IBM SPSS 23.0 program. Results: The mean score of medication adherence of the elderly with chronic disease was $4.48{\pm}2.35$. Experiences of side effects (${\beta}=.31$, p< .001), use of over-the-counter pain medication (${\beta}=.19$, p= .009), and family function (${\beta}=.16$, p= .031) were identified as significant predictors. The final model explained 18.0% of the variation of medication adherence of the elderly with chronic disease taking non-opioid analgesics (F= 12.30, p< .001). Conclusion: Therefore, as a strategy to improve medication adherence of the elderly with chronic disease, therapeutic intervention should be developed to improve family function and to manage with personalized plans considering experiences of side effects and use of over-the-counter pain medication.

This study aimed to develop a planned discharge nursing intervention guideline for patients with pneumothorax, and to examine its influence on drug compliance, knowledge about disease, compliance level with therapeutic regimen, and nursing satisfaction. Methods: The planned discharge nursing intervention guideline was developed based on comprehensive literature reviews and clinical experiences. Patients having video-assisted thoracoscopic surgery at a single general hospital were allocated to either intervention (n=30) or control group (n=29). Participants in the intervention group were administered planned discharge nursing intervention thrice, 30 minutes each, by a cardiovascular nurse. Standard care was provided to patients in the control group. Data were collected from March, 2010 to December, 2010. Results: Participants in the intervention group presented statistically significant improvement in drug compliance (t=-2.05, p=0.044), pill count (t=-2.61, p=0.011), knowledge about disease (t=-4.39, p=0.001), and nursing satisfaction (t=-4.13, p=0.001). No significant difference in compliance levels was observed with standard therapeutic regimen. Conclusion: Planned discharge nursing intervention can be successfully implemented for patients undergoing thoracoscopic surgery. Further research is required to evaluate long-term effects like complication or relapse.

Purpose: This study was conducted to measure medication adherence and perceptions of anticoagulation therapy and its relationship to patients taking warfarin. Methods: in a cross-sectional survey, 150 patients taking warfarin who had visited an outpatient clinic of a cardiovascular center in Seoul were included as research subjects. Medication adherence was measured using a visual analogue rating scale (VAS). Barriers and attitudes toward adherence, and oral anticoagulation knowledge, were measured using a structured questionnaire. Participants' medical records also were reviewed to identify clinical characteristics. Results: About one third of the participants (30.7%) reported medication adherence as 100%. The major barriers to adherence were identified as "Forgetting the time of medication" and "Not carrying their medication". Overall attitudes toward medication adherence were high, but oral anticoagulation therapy knowledge was low. To determine the relationship of medication adherence and perceptions of anticoagulation therapy, participants were stratified into three groups, based on their medication adherence levels (high adherence, moderate adherence, low adherence). Participants in the high adherent group more likely to be older (OR: 1.04, 95% CI: 1.005-1.071) and to have positive attitudes toward medication adherence (OR: 1.12, 95% CI:1.013-1.229) compared to the other two groups. Conclusion: The results show that age and attitude exerts significant influence on medication adherence in patients taking warfarin.

Purpose: This study was aimed to describe the level of medication adherence and to identify the impact of cognitive function and self-efficacy on medication adherence of elderly patients with chronic disease. Methods: The descriptive study included 303 patients over 65 years with chronic diseases from two medical centers in Cheonan city. Data were collected from July to November 2011. A questionnaire including questions on the Korean version of mini-mental state examination (MMSE-K), self-efficacy and medication adherence were completed by the subjects. Data were analyzed using the SPSS/WIN 20.0 program. Results: The mean score of medication adherence was $1.4{\pm}1.6$. In univariate analysis, exercise (t=2.85, p=.005), type of disease (F=3.91, p=.001) and self-efficacy (r=-.57, p<.001) were the significant factors related to medication adherence. Linear regression analysis demonstrated that self-efficacy (${\beta}$=-.57, p<.001) was a significantly associated factor with medication adherence. Self-efficacy explained about 33% of the total variance of the medication adherence in elderly patients. Conclusion: The results suggest that self-efficacy to medication can be a facilitator to medication adherence in elderly patients. However, these results indicate that there remains much work to be done in identifying other predictors of medication adherence of elderly patients with chronic diseases.

Purpose: Dyslipidemia was a known risk factor for cardiovascular disease and was a leading cause of mortality in worldwide. This study aimed to determine the factors associated with prevalence and medication treatment of dyslipidemia in Korean adult population. Methods: In this study, based on the criteria set by the Korean Society of Lipidology and Atherosclerosis, the factors associated with prevalence and medication treatment of dyslipidemia was evaluated in a population of 12,506 people ($age{\geq}20$), who participated in the Korean National Health and Nutrition Examination Survey (2013-2015). The findings were tested by using multivariate logistic regression. Results: Dyslipidemia prevalence rate was 36.5%. Among populations with dyslipidemia, 17.5% were treated with lipid-lowering drugs. In the multivariate logistic regression model, male, increase in age, lower education level, non-drinker, current smoking, less physical activity, increase of body mass index, hypertension, and diabetes were associated with an increased odd of dyslipidemia. Female, increase in age, higher income, excess fat intake, hypertension, diabetes, myocardial infarction, and angina were associated with an increased odd of medication treat. Conclusion: The results of this study could be used to screen patients at the high risk for dyslipidemia or to predict medication adherence.

Purpose: The purposes of this study were to examine the relationships between health literacy, self-efficacy, social support, and medication adherence and to determine its impact on medication adherence in the elderly. Methods: This study was a descriptive research study. Structured questionnaires were used for survey with a convenience sample of 220 elderly in a community. Data were analyzed using descriptive statistics, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression with IBM SPSS 18.0. Results: The mean scores of health literacy, self-efficacy, social support, and medication adherence were $35.89{\pm}19.39$, $55.34{\pm}7.44$, $86.54{\pm}15.90$ and $4.82{\pm}1.83$, respectively. There were significant correlations between health literacy, self-efficacy, social support, and medication adherence. Social support (${\beta}=.23$, p=.001) and health literacy (${\beta}=.21$, p=.002) were significantly associated factors with medication adherence. Conclusion: This finding showed that nursing interventions to promote medication adherence in the elderly group should focus on social support program and health literacy intervention.

This study was performed to identify the health behaviors and medication compliances of hypertensive patients in a rural area, from May 1 to July 31. 2001. The subjects were 100 hypertensive patients who were registered at the Health Center in Goeje City. The data was collected by face-to-face interviews with a 25-item questionnaire on health behaviors, and analyzed by the Chi-square test on each variable. The results were as follows: Approximately 76% of the subjects were currently taking drug medication. In the comparison of health behavior rates between male and female, there were statistically significant differences in smoking (p< .000), alcohol(p< .003), low salt diet(p< .014), and the health behavior rates of female were higher than those of male. In the comparison of socioeconomic factors by medication compliance, there was statistically significant difference in sex(p< .001), and the medication compliance rate of female was higher than that of male. In the comparison of subjects' perception by medication compliance, there were statistically significant differences in seriousness of hypertension (p< .001) and medication period for hypertension care (p< .004), The medication compliance rate of the group of subjects who took the threat on their hypertension seriously was higher than that of the group who didn't, and the medication compliance rate of the group who knew that they should take medication for the rest of their life was higher than that of the group who didn't. These results suggest that community health education programs and distribution of information must be emphasized in order to increase medication and to encourage behavior changes for promoting health.

Purpose: The purpose of this study is to examine factors influencing medication adherence in patients with hypertension. Methods: This study carried out a secondary analysis of data from the 2008 Korean National Health and Nutrition Examination Survey (KNHANES). Stratified sampling was used to select a participant sample that was representative of patients with hypertension throughout the country. Using the SPSS/WIN 18.0 program, data were analyzed using descriptive statistics, $x^2$ test, t-test, and logistic regression. Results: Of the patients with hypertension, 8.8% had showed non-adherence to medication. Medication adherence was associated with age, spouse, Medicare insurance, number of other diseases, and current smoking status. The cases with older age, a spouse, Medicare insurance, higher number of other diseases, and no current smoking status showed significantly high medication adherence. Conclusion: Nursing interventions and further studies are needed to achieve high levels of medication adherence based on factors influencing medication adherence such as age, spouse, Medicare insurance, number of other disease, and current smoking status.

Purpose: The purpose of this study was to explore socio-demographic, clinical and psychological factors associated with medication adherence among patients with chronic heart failure (CHF). Methods: In a cross-sectional survey, 133 patients with CHF who had visited a clinic located in Seoul participated. Medication adherence (MA) was measured using a single item visual analogue rating scale (VAS). Barriers and attitudes toward adherence, and depression were measured using a structured questionnaire. Medical records were reviewed to identify their clinical characteristics. Multivariate logistic regression was performed identify factors affecting medication adherence. Results: About one third of participants (31.1%) reported their MA as 100%. Overall attitudes on MA were highly positive and 49 (36.8%) of participants were depressive. MA was associated with significantly barriers (p<.001), attitudes (p<.001), age (p<.001), and duration of disease (p<.001). The high adherent group had significantly less barriers than other groups (OR=.389, p=0.02). Conclusion: This study indicates that barriers and attitudes toward MA were the most important factors affecting their adherence to HF medication. To improve MA for patient with CHF, the nursing strategies which can lead poor adherent patients to their optimal level should be developed.
