        Perception of Long-Term Oxygen Therapy for Chronic Lung Diseases May Affect Poor Adherence in Korea

        Hyun-Kyung Lee, M.D., Ph.D.,Hyo Jin Kim, M.D.,Hongyeul Lee, M.D.,Ji Young Yang, M.D.,Jae Ha Lee, M.D.,Seung Won Ra, M.D., Ph.D.,SungMin Hong, M.D.,Ho Young Lee, M.D.,Sung Hyun Kim, M.D.,Mi-Yeong Kim, 대한결핵및호흡기학회 2024 Tuberculosis and Respiratory Diseases Vol.87 No.1

        Background: Long-term oxygen therapy (LTOT) improves the survival of patients withhypoxemia due to chronic respiratory diseases. The clinical outcomes of LTOT arestrongly associated with patient adherence. To improve the adherence of patients,physicians have focused on the efficacy of LTOT. However, poor adherence may stemfrom patients’ perceptions of LTOT. Herein we evaluated patients’ perceptions of LTOTaffecting adherence. Methods: We conducted a cross-sectional survey study using descriptive, open, andclosed-ended questionnaire. Patients using oxygen therapy (OT) or requiring it butavoiding OT responded to the questionnaires at three university hospitals. Results: Seventy-nine patients responded to the questionnaires. The number of patientsusing home and portable OT was 69 (93%) and 37 (46.3%), respectively. Patientswith good adherence were 22 (30.1%). Among patients with good adherence, 90.9%used oxygen according to physicians’ prescriptions whereas only 37.3% of those withpoor adherence followed physicians’ prescriptions (p<0.01). The reasons for avoidingusing home OT were fear of permanent use (50%), unwanted attention (40%), and lackof symptoms (40%). They avoided portable OT because of unwanted attention (39%),heaviness (31.7%), and lack of symptoms (21.6%). Conclusion: Patients on LTOT had the perception of the misunderstanding the effectsof OT and of psychosocial barriers to initiate or use LTOT. Considering these findings,health professionals need to provide effective education on the purpose of LTOT toimprove patient adherence to OT and provide sufficient support for the management ofpsychosocial barriers in patients using LTOT.

        수술 후 재발한 유두상 갑상선 암의 경부 재발 위험인자에 대한 연구

        하태권,유성목,김상효,Tae Kwun Ha,M.D.,Sung Mock Ryu,M.D. and Sang Hyo Kim,M.D. 대한갑상선-내분비외과학회 2010 The Koreran journal of Endocrine Surgery Vol.10 No.4

        Purpose: Papillary thyroid carcinoma (PTC) is known to have a favorable prognosis and long-term survival due to its biologic characteristics of slow growth and late distant metastasis. However, its characteristic of lymph node metastasis has resulted in a high incidence of neck recurrence and only rare lung metastasis. The objective of this study is to analyze the characteristics of recurrent or persistent thyroid cancer and to evaluate the risk factors for the development of recurrence. Methods: We retrospectively reviewed 479 consecutive cases of PTC and these patients had undergone surgical operations from January 2004 to December 2006. We assessed age, gender, the tumor characteristics, the operative methods and the recurrence patterns, and the correlations between these factors and recurrence were analyzed. Results: Of the 479 patients with PTC and who were initially treated with surgery at our hospital, 42 patients (8.8%) had recurrent disease. Univariate analysis showed that an age less than 45 years, male gender, extra-thyroidal extension, lymph node metastasis, multifocality, bilaterality and neck node dissection were related to a higher rate of recurrence. Of these, lymph node metastasis and central or lateral neck node dissection were the independent risk factors for recurrent PTC on the multivariate analysis. Conclusion: The significant factors influencing locoregional recurrence and distant metastasis were cervical lymph node metastasis and incomplete neck node dissection. In order to reduce the rate of recurrence of PTC, an exact preoperative evaluation of the nodal status and formal neck node dissection are recommended during the initial surgery in patients who have these factors of recurrence.
