A phenomenological study of hospital readmissions of Chinese older people with chronic obstructive pulmonary disease / CUHK electronic theses & dissertations collection

January 2015 (has links)
Hospital readmission is prevalent among people with chronic obstructive pulmonary disease (COPD), particularly among older people in Hong Kong. Evidence shows that hospital readmissions exert a considerable impact on patients. Studies in this area primarily identify various associative factors based on the perspectives of health professionals. However, these factors are inadequate in illustrating the needs of older people and in illuminating the phenomenon of hospital readmissions. A thorough understanding of the issue can be achieved if the related experiences are interpreted from the perspective of the patients and in terms of their context. Understanding of their experiences has paramount significance in uncovering the unmet needs of patients and in informing the provision of healthcare services. Yet, there is a dearth of studies unfolding the experiences of Chinese older people. / This study aimed to explore and describe the lived experience of hospital readmissions of Chinese older people with COPD and to identify Chinese socio-cultural influences on the experience. Understanding was acquired through descriptive phenomenology. Twenty-two Chinese older people aged 62 to 89 were recruited by purposive sampling. They had been readmitted 4 to 14 times in the previous year. The older people were interviewed once during their hospitalization, and their readmission experiences were elicited from these unstructured interviews. Narrative descriptions were analyzed using the phenomenological method described by Giorgi (1985). / The general structure of the lived experience of hospital readmissions of Chinese older people with COPD reveals that older people refrain from unnecessary readmissions because they regard hospital care as the last resort in relieving breathlessness. When their breathlessness becomes intolerable, they perceive the urgency of surviving the distress. Craving for survival, they seek hospital readmission, which provides them immediate relief from the imminent threat. After being readmitted to a hospital, they feel powerless when their need for hospital care is disregarded by their doctors. Considering themselves as demanding to their families in daily lives, older people remain conscious of relieving their burden during their periods of hospital readmission because they regard this as the only opportunity to relieve their burden. Older people come to realize hospital readmissions are unavoidable after they put every effort to refrain from it but hospital care remains necessary. They further rationalize hospital readmissions as inevitable and resign themselves to it because of their perception of aging, doctors’ accounts of COPD, experience with and knowledge of the disease, and belief in fate. This acceptance of the inevitability of hospital readmissions precipitates an attitudinal shift toward the belief of living for the moment. Their past experiences inspire them to be satisfied with the current state of living and engage the present. This positive outlook enables them to embrace the experiences of hospital readmissions into their lives. Six invariant constituents emerged from the lived experience. The constituent “refraining from unnecessary readmissions” describes how older people manage their diseases in relation to hospital readmissions. “Craving for survival” explains why they seek hospital readmissions. “Feeling being disregarded and powerless” and “being conscious of relieving burden to families” characterize their experience of hospital readmissions. “Resigning to hospital readmissions” illustrates how they understand the recurrence of this phenomenon and “living for the moment” illuminates how they live with their experiences. / A deep understanding of hospital readmissions is embodied in the experiences of older people. The findings emphasize that hospital readmissions among Chinese older people are complex experiences shaped by their sociocultural context. The meanings of hospital readmissions to older people are influenced by their assumption of a submissive patient role, collectivism, external attribution style, and past life experiences. Although older people appear to accept and cope well with hospital readmissions, this study uncovers their needs as they move to and fro the hospital and home. The findings of this study offer implications in promoting the wellness of Chinese older people as they go through this revolving door. / 再次住院在患有慢性阻塞性肺病人士中相當普遍,尤其是在中國老年患者。研究證據顯示再次住院對病人有很大的影響。現有的研究偏重於從醫務人員角度尋找不同的關聯因素,但該些因素並不足以反映老年人的需要以及解釋再次住院的現象。只有透過病人的觀點以及結合他們的背景來闡釋這些相關經驗,才能作出深入了解。了解病人的再次住院經驗有助於找出病人的需要以及指引醫療服務的提供。然而,有關中國老年人再次住院經驗的探討相當缺乏。 / 是次研究目的是探討和描述患有慢性阻塞性肺病的中國老年人再次住院的體驗,以及認識中國社會文化對再次住院經驗的影響。研究採用描述現象學方法。研究以立意抽樣方式選取了22名62至89歲的中國老年人。他們在去年入院次數為4至14次。這些老年人在住院期間均接受一次非結構式訪談以了解他們的再次住院經驗。這些敘述性描寫再按 Giorgi (1985) 的現象學方法作出分析。 / 患有慢性阻塞性肺病中國老年人再次住院的體驗的通用結構顯示他們避免不必要的再次住院,因為他們將住院護理視為紓緩呼吸困難的最後方法。當他們的呼吸困難惡化至無法忍受,他們會感受到從危病中活下來的迫切性。因著渴望生存的意識,他們尋求再次住院以即時消除緊迫的生命威脅。再次入院後,對於醫生漠視其住院護理的需要,他們感到無力。由於考慮到他們在日常生活中對家人的需求頗多,老年人以再次住院其間來減輕家庭負擔,因他們視這其間為唯一能減輕家庭負擔的機會。儘管老年人盡能力以避免再次入院,但他們依然需要住院護理,老年人逐漸意識到再次住院為無可避免。由於老年人對於老化的感知、醫生對慢性阻塞性肺病的解明、患病經驗和對疾病的相關知識以及相信命運的看法,他們更將再次住院合理化為無可避免並順從。接受再次住院為無可避免促成他們的態度轉變為活在當下。過去的經驗令他們對目前的生活感到滿意並希望活在當下。這個正面想法令他們將再次住院接納為生活的一部份。六個不變組成要素呈現於老年人的再次住院體驗當中。組成要素「避免不必要的再次住院」描述老年人如何管理慢性阻塞性肺病以避免再次住院。「渴望生存」解釋了他們尋求再次住院的原因。「感到被忽略和無力」以及「減輕家庭負擔的意識」敘述了他們再次住院的經驗。「順從再次住院」說明了他們對再次住院現象發生的理解,而「活在當下」說明了他們如何接納再次住院經驗。 / 對於再次住院的深入了解具體表現於老年人的經驗當中。是次研究結果強調,老年人再次住院是由他們的社會文化背景塑造而成的複雜經驗。對於老年人而言,再次住院的意義受到他們對順從性病人角色的假設、集體主義觀念、外部歸因以及過往的生活經驗所影響。雖然老年人似乎接受並適應再次住院,是次研究發現了他們在這現象中的需要。研究結果對於促進再次住院的中國老年人的健康帶來新的啟示。 / Tang, Wing Ki. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2015. / Includes bibliographical references (leaves 342-393). / Abstracts also in Chinese. / Title from PDF title page (viewed on 05, October, 2016). / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only.

Development and validation of a measure of quality of life for Chinese people living with HIV and AIDS in Hong Kong. / CUHK electronic theses & dissertations collection

January 2013 (has links)
隨著高效能抗病毒藥物治療的推出,愛滋病病患者的不良健康狀況得以逆轉。愛滋病病毒感染已不再是無藥可治的絶症,而是一種需要終生服藥的慢性疾病。但是,藥物的出現並未減輕疾病本身對病患者的心理健康打擊,例如被社會歧視,而藥物的副作用則被大量發現,藥物治療的進步並不一定能改善病患者的生活質素,而監測患者的生活質素便成為必要。但是,目前供病患者所使用的生活質素量表,均於推出高效能抗病毒藥物治療前或不久後發展而成,並在西方國家使用,因此,此項研究的目的是要發展和確認一份與本土文化和環境背景相關的生活質素量表,供香港的華藉愛滋病病毒感染者和病患者所使用。 / 此研究項目共分為三個階段。第一階段集中於項目產生,以質性研究方法探討愛滋病病毒感染者和病患者對生活質素含義和組成內容的看法。此階段共招募了36位參與者(30男、6女)進行面對面的單獨訪問。以主題分析方法,找出了10個生活質素的類別及65個項目,並以它們為藍本構成量表的項目庫。項目庫的表面效度和全面性經參與者的確認後,新的生活質素量表CHAQOL才成立。 / 第二階段集中於項目删減。此階段以統計方法為主導,删減多餘和缺乏一貫性的項目。從168位參與者的數據分析所得,保留40個項目便能使新量表達致最理想的內部結構和項目的一致性和變異性,結果並顯示香港華藉愛滋病病毒感染者和病患者的生活質素由六個因素模型構成,這包括:「生活滿意度」、「情緒健康」、「身體健康」、「羞辱和歧視」、「親密關係」和「抗病毒治療的信念」。 / 第三階段集中測試CHAQOL量表的心理計量特質,此階段新招募了239位參與者,再測試可信度的初試和複試相隔兩週進行,分析結果顯示,40個項目的加權卡帕係數為0.46至0.93,在六個範圍組內的相關係數為0.82至0.97。至於內部一致性可信度,克隆巴赫係數為0.63至0.93。這些結果皆顯露CHAQOL量表是可信的。至於效度方面,驗證性因素檢測結果支持CHAQOL量表是由六個因素模型構成的,而多項特質排列檢驗分析結果亦顯示CHAQOL量表有良好的項目會聚性,其在六個範圍組內的會聚成功率為75%至100%,與此同時,CHAQOL量表內的所有範圍組內的區分成功率為71%至100%,只有「情緒健康」範疇得到較不理想的區分成功率。CHAQOL量表在區分已知有差異組別上的表現良好,六個構成量表的範疇均能區分有不同臨床特徵的病患者的主觀感受,這包括病情、病徵和藥物治療副作用的嚴重程度。已被確認有效度的通用生活質素量表WHQOOL-BREF和HIV Stigma量表的子量表被用作檢測CHAQOL量表的同時效度,檢測結果顯示較強至中等強度的相關性只存在於CHAQOL量表的「滿意生活度」、「情緒健康」、「身體健康」的三個範疇和WHQOOL-BREF量表內的各個範疇,但不存在於CHAQOL量表內的餘下範疇,而類似的最強相關性關係也存在於HIV Stigma量表的子量表和CHAQOL量表內的「羞辱和歧視」範疇。總括來說,測試結果提供初步科學證據支持CHAQOL量表的信度和效度。 / With the introduction of highly active antiretroviral therapy (HAART), the health status of patients with acquired immune deficiency syndrome (AIDS) becomes reversible. The human immunodeficiency virus (HIV) infection is no longer an incurable fatal disease, but a chronic disease that requires lifelong treatment. However, the emergence of HAART does not lessen the detrimental impact of the disease on the psychosocial well-being of patients, such as the effect of social stigmatization. The side effects of HAART are also well documented. Therefore, the advancement in treatment not necessarily improves the quality of life (QOL) of patients and monitoring patients’ QOL becomes crucial. Nevertheless, existing QOL measures specifically for HIV/AIDS patients were developed either before or shortly after HAART, which were used in Western countries. Therefore, the aim of this study is to develop and validate a culturally and contextually relevant QOL measure for the Chinese people living with HIV/AIDS in Hong Kong (HK). / This study comprised three phases. Phase One focused on generating items for the QOL measure. Qualitative research methodology was adopted to explore the meaning and constituents of QOL from the perspective of HIV/AIDS patients. Thirty-six (30 male, 6 female) participants were recruited for face-to-face individual interviews. Using thematic analysis, 10 QOL categories were identified, and 65 items were devised to form an item pool. The face validity and comprehensiveness of the item pool was affirmed by the participants. The initial draft of new measure, named CHAQOL, was thus established. / Phase Two focused on item reduction. A statistically driven approach was adopted to eliminate any psychometrically redundant and incoherent items. Based on the data collected from 168 participants, 40 items were retained to give the optimal internal structure and item consistency and variability. This initial version suggested a six-factor model of QOL for the Chinese people living with HIV/AIDS of HK. The six factors are: "life satisfaction", "emotional well-being", "physical well-being", "stigma and discrimination", "intimate relationships", and "belief in antiretroviral therapy" (ART). / Phase Three focused on testing the psychometric properties of the CHAQOL. Another sample of 239 HIV/AIDS participants was recruited. The test and retest conducted two weeks apart. The weighted kappa values of 40 items ranged between 0.46 and 0.93 whereas the intraclass correlation coefficients of six QOL dimensions ranged between 0.82 and 0.97. For the internal consistency, Cronbach’s alpha ranged from 0.63 to 0.93. The results demonstrated CHAQOL to be reliable. In the evaluation of construct validity, the results of confirmatory factor analysis supported the six-factor model underlying CHAQOL. Multitrait scaling analysis showed that CHAQOL had good item convergent success rate ranging from 75% to 100% for the six subscales. All subscales of the CHAQOL, except the emotional well-being, had good item discriminant validity with an item discriminant success rate ranging from 71% to 100%. Known-group comparison indicated that the CHAQOL was able to distinguish the differences in all six QOL dimensions between Chinese HIV-infected people with different levels of disease severity, symptom severity and severity of ART-related side effects. The validated generic measure WHOQOL-BREF (HK) and the HIV Stigma subscale were used to examine the concurrent validity with the CHAQOL. Strong-to-moderate correlations were found only between the CHAQOL dimensions “life satisfaction, “emotional well-being, and “physical well-being, as well as the domains of WHOQOL-BREF (HK), but not for the remaining dimensions. Similarly, strongest correlations were found between the CHAQOL subscales “stigma and discrimination and the HIV stigma subscale. The results provide evidence on the reliability and validity of the CHAQOL. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Ho, Choi Fung. / "December 2012." / Thesis (Ph.D.)--Chinese University of Hong Kong, 2013. / Includes bibliographical references (leaves 244-272). / Electronic reproduction.
