Purpose: The study aimed to clarify the concept of spiritual self-care in hospice team members. Methods: To analyze the concept of spiritual self-care of hospice care team, the study was carried out using Schwartz-Barcott and Kim's hybrid model including theoretical, fieldwork and final analytic stages. In the theoretical stage, 'spirituality', 'spiritual well-being', 'spiritual health', 'spiritual care', and 'self-care' were set as search terms, and the resulting 107 related works of domestic and international literature were analyzed. In the field survey stage, data were collected from nurses and spiritual experts with more than 5 years of experience in spiritual self-care. Results: The concept of spiritual self-care is to realize the meaning and purpose of life while constantly maintaining relationships with oneself, neighbors, communities, and the absolute, utilize transcendence and internal resources, strengthen professional competence, maintain work-life balance, and achieve spiritual well-being. It was identified as a dynamic state to realize. The quality attributes of the concept of spiritual self-care were found to have 5 attributes and 15 indicators. Conclusion The attributes and indicators derived through this study will be helpful in understanding the concept of hospice team members' spiritual self-care. In addition, as a way to continuously grow and train professional hospice team members, it can be used to develop a spiritual self-care assessment tool and an educational program to prevent burnout.

Objective: To demonstrate the effect of daily treatment time on recovery of functional outcomes and how each type of rehabilitation treatment influences the improvement of subgroups of functional outcomes in stroke patients. Methods: We conducted a retrospective study in 168 patients who were admitted to the Department of Rehabilitation Medicine between 2015 and 2016. Patients who experienced their first-ever stroke and unilateral lesions were included. All patients underwent conventional rehabilitation treatment, and each treatment was administered one to two times a day depending on individual and treatment room schedules. Based on the mean daily treatment time, patients were divided into two groups: a high-amount group (n=54) and low-amount group (n=114). Outcomes were measured through the Korean version of Modified Barthel Index (MBI), FuglMeyer Assessment of the upper extremity, Trunk Impairment Scale (TIS), and Berg Balance Scale (BBS) scores on admission and at discharge. Results: The functional change and scores at discharge of MBI, TIS, and BBS were greater in the high-amount group than in the low-amount group. Among various types of rehabilitation treatments, occupational therapy training showed significant correlation with MBI, TIS, and BBS gain from admission to discharge. Conclusion The amount of daily mean treatment in post-stroke patients plays an important role in recovery. Mean daily rehabilitation treatment time seems to correlate with improved balance and basic activities of daily living after stroke.

OBJECTIVE: To explore the feasibility of cardiopulmonary exercise test (CPET) in leukemia patients after chemotherapy. METHODS: Leukemia patients with histologically confirmed hematologic malignancies were reviewed. We evaluated for CPET, between receiving chemotherapy and undergoing stem cell transplantation after 2 weeks. We recorded exercise testing and physiologic parameters during CPET between January 2013 to May 2015. All patients were subjected to symptoms limited to exercise testing, according to the Modified Bruce Protocol. We considered that if respiratory exchange ratio achieved was over 1.10, participants had successfully completed CPET. We dichotomized all participants into two groups (normal group, normal range of resting heart rate; higher group, over 100 per minute of heart rate). RESULTS: 30 patients were finally enrolled. All participants had no adverse effects during the exercise test. Mean peak double product was 26,998.60 mmHg·beats/min (range, 15,481–41,004), and mean peak oxygen consumption (VO₂ peak) was 22.52±4.56 mL/kg/min. Significant differences were observed in the normal group with VO₂ peak (mean, 24.21 mL/kg/min; p=0.027) and number of prior intensive chemotherapy, compared to the higher group (mean, 1.95; p=0.006). CONCLUSION: Our results indicate that CPET in leukemia patients before stem cell transplantation was very safe, and is an efficient method to screen for patients with poor cardiac functions. As CPET presents the parameters which reveal the cardiopulmonary functions, including VO₂ peak, double product and exercise capacity, this exercise test would help to predict the physical performance or general condition of the leukemia patients.

Objective: We conducted a systematic review and meta-analysis to analyze the effects of cardiac rehabilitation (CR) on post-discharge prognoses of patients with acute myocardial infarction (AMI). Methods: A literature search was conducted through four international medical and two Korean databases. Primary outcomes for the effectiveness of CR included all-cause mortality, cardiovascular mortality, recurrence, revascularization, major adverse cardiovascular event, major adverse cardiocerebrovascular event, and readmission. We summarized and analyzed results of studies about CR for AMI, including not only randomized controlled trials (RCTs) but also non-RCTs. We calculated the effect size separately by the study type. Results: Fourteen articles were finally selected. Of these, two articles were RCTs, while 12 were non-RCTs. In RCTs, the overall mortality rate was lower in the group that participated in CR than that in the conventional care group by 28% (relative risk=0.72; 95% confidence interval, 0.34–1.57). Among non-RCTs, CR participation significantly decreased the overall risk of mortality. Moreover, the rates of recurrence and major adverse cardiovascular events were lower in the group that participated in CR compared to those in the non-CR group. Conclusion The meta-analysis shows that CR reduces the risk of re-hospitalization and all-cause mortality after AMI, compared to no participation in CR. This outcome was seen in RCTs as well as in non-RCTs. More studies are necessary for concrete conclusions about the beneficial effects of CR after AMI in various settings.

OBJECTIVE: To investigate factors associated with enrollment and participation in cardiac rehabilitation (CR) in Korea. METHODS: Patients admitted to four university hospitals with acute coronary syndrome between June 2014 and May 2016 were enrolled. The Cardiac Rehabilitation Barriers Scale (CRBS) made of 21-item questionnaire and divided in four subdomains was administered during admission. CRBS items used a 5-point Likert scale and ≥2.5 was considered as a barrier. Differences between CR non-attender and CR attender, or CR non-enroller and CR enroller in subscale and each items of CRBS were examined using the chi-square test. RESULTS: The CR participation rate in four hospitals was 31% (170 of the 552). Logistical factors (odds ratio [OR]=7.61; 95% confidence interval [CI], 4.62–12.55) and comorbidities/functional status (OR=6.60; 95% CI, 3.95–11.01) were identified as a barrier to CR enrollment in the subdomain analysis. Among patients who were enrolled (agreed to participate in CR during admission), only work/time conflict was a significant barrier to CR participation (OR=2.17; 95% CI, 1.29–3.66). CONCLUSION: Diverse barriers to CR participation were identified in patients with acute coronary syndrome. Providing the tailored model for CR according to the individual patient's barrier could improve the CR utilization. Further multicenter study with large sample size including other CR indication is required.

Background: Recently, active surveillance (AS) has been introduced as an alternative to early surgery (ES) for the management of papillary thyroid microcarcinoma (PTMC), because of its indolent features and low mortality. However, its cost effects have not been determined and the findings of current studies differ, according to each country’s medical system. Methods: A Markov model was constructed to compare the cost-effectiveness of AS and ES, based on a reference case of a 40-year-old patient diagnosed with PTMC. Costs and transition probabilities were derived from previous clinical studies in Korean populations, and the incremental cost-effectiveness ratio (ICER) and net monetary benefit (NMB) were calculated. The willingness-to-pay (WTP) threshold was set at USD 100,000 per quality-adjusted life year (QALY) gained. Sensitivity analyses were conducted to address the uncertainties in the model’s variables. Results: From the base scenario, the cumulative costs and effectiveness were both higher in ES than AS. The ICER for ES, compared with AS, was USD 6,619.86/QALY, lower than the set WTP. The NMB difference between AS and ES increased across the stages (USD 5,980 at the first stage and USD 159,667 at the last stage). The ICER increased along with decreasing age and increasing cost of surgery. The higher the ES utility score and the lower that of AS, the more cost-effective ES, with WTP set at USD 30,000. Conclusion In the current Korean medical system, ES is more cost-effective than AS. ES is more cost-effective as it is diagnosed at young age and followed-up for a long time.

Background: There is debate about ultrasonography screening for thyroid cancer and its cost-effectiveness. This study aimed to evaluate the cost-effectiveness of early screening (ES) versus symptomatic detection (SD) for differentiated thyroid cancer (DTC) in Korea. Methods: A Markov decision analysis model was constructed to compare the cost-effectiveness of ES and SD. The model considered direct medical costs, health outcomes, and different diagnostic and treatment pathways. Input data were derived from literature and Korean population studies. Incremental cost-effectiveness ratio (ICER) was calculated. Willingness-to-pay (WTP) threshold was set at USD 100,000 or 20,000 per quality-adjusted life year (QALY) gained. Sensitivity analyses were conducted to address uncertainties of the model’s variables. Results: In a base case scenario with 50 years of follow-up, ES was found to be cost-effective compared to SD, with an ICER of $2,852 per QALY. With WTP set at $100,000, in the case with follow-up less than 10 years, the SD was cost-effective. Sensitivity analysis showed that variables such as lobectomy probability, age, mortality, and utility scores significantly influenced the ICER. Despite variations in costs and other factors, all ICER values remained below the WTP threshold. Conclusion Findings of this study indicate that ES is a cost-effective strategy for DTC screening in the Korean medical system. Early detection and subsequent lobectomy contribute to the cost-effectiveness of ES, while SD at an advanced stage makes ES more cost-effective. Expected follow-up duration should be considered to determine an optimal strategy for DTC screening.
