The evolving experience of illness for Chinese women with breast cancer: a qualitative study.

The study of illness meaning in cancer in western communities has usually focused on causal attributions. We report a phenomenological study of 17 Hong Kong Chinese women with breast cancer, interviewed on completion of initial treatment, and describe how the illness experience and hence, meaning evolves for women in the Hong Kong Chinese culture. Themes arising from the identification and treatment of the disease include the difficulty of living in uncertainty and of maintaining and regaining normalcy in a superstitious society. The initial uncertainty of disease detection and the diagnostic process are characterized by shock and disbelief mingled with fear of death. Treatment choice presents women with difficulties arising from more uncertainty over the pressure to make quick decisions and the dilemma of death or mutilation. Following treatment, re-evaluation, re-prioritizing and positive life-re-evaluation occur. Changes in appearance proved problematic for those women who tried to hide their disease to protect themselves against stigmatization and social exclusion. In many ways, these findings parallel studies on western populations, suggesting that a common disease-medical care process is a predominant influence in shaping breast cancer experience. Implications for care are drawn from these data.

Smoking and perceived health in Hong Kong Chinese.

This population-based cross-sectional study examined the associations between smoking and perceived health in Hong Kong. 6117 healthy Chinese (3053 men, 3064 women), aged 25-74 years, were randomly selected for telephone interviews in Hong Kong in 1994-96. Adjusted odds ratios (ORs) of having poor or very poor perceived health (against good or very good) were calculated. In men, the ORs (and 95 percent confidence intervals) for current smokers in young (25-39) and middle age (40-59) were close to unity, but that of 1.97 (1.01, 3.85) in old age (60-74) was significantly raised. The adjusted ORs for male quitters were 1.98 (0.43, 9.14), 1.70 (0.75, 3.81) and 2.59 (1.23, 3.33) for young, middle and old age, respectively. Compared with current smokers, the adjusted ORs for quitters was 2.30 (1.07, 4.92) for those who had quit for less than 5 years, 2.02 (0.80, 5.11) for 5-9 years and 1.14 (0.47, 2.75) for 10 years or more. Among former smokers, each year of quitting was associated with 7 percent reduction in reporting poor or very poor perceived health with OR of 0.93 (0.85, 1.01). In women, the ORs were 1.95 (1.15, 3.28) for current and 1.54 (0.60, 3.94) for former smokers. In both genders combined, the overall ORs were 1.41 (1.04, 1.92) for current and 1.94 (1.27, 2.97) for former smokers. In conclusion, former smokers apparently had the worst perceived health but long-term quitting was beneficial. Overall, current smokers had worse perceived health than never smokers, but in men the excess risk was mainly observed in old age. The perceived health of smokers may have implications for the approaches used in smoking cessation.

The mediating role of optimism on post-radiation quality of life in nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) is prevalent in southern China. In non-welfare countries, eating difficulties after radiotherapy may hinder NPC patients' short-term quality of life (QoL) especially regarding work and finance. This study explored the positive mediating role of optimism on the relationship between eating ability and QoL of Chinese NPC patients who received radiotherapy in Hong Kong. A sample of 211 newly referred patients were recruited and followed-up face-to-face or by telephone at four (post-radiation 1) (FU 1) and eight (post-radiation 2) (FU 2) months from baseline. QoL was measured by the FACT-G (Chinese). Optimism and eating ability were measured by two 11-point self-rated items. Mediating effects were tested with a series of multiple regression models. After adjustment for pre-radiation QoL, socioeconomic status and cancer stage, optimism significantly mediated the relationship between eating ability at FU 1 and overall QoL at FU 2, in particular physical and social/family well-being. This study is the first to underpin the mediating role of optimism on QoL of NPC patients. Faced with aversive side-effects of radiotherapy, facilitating positive thinking in Chinese NPC patients may accelerate their short-term post-radiation adjustment.

Participation and satisfaction with surgical treatment decision-making in breast cancer among Chinese women.

PURPOSE: To report Chinese women's preferred and perceived participation in breast cancer treatment decision making (TDM), describe influences on women's participation preference and participation congruence (PC) (correspondence between preferred and actual amount of participation in TDM), and explore subsequent satisfaction with TDM. PATIENTS AND METHODS: Of 172/211 eligible and available Chinese women recently undergoing breast cancer surgery at one of six Hong Kong government hospitals 154 (89.5%) were recruited. Within 12 days after surgery, women provided interview information on preferred and perceived TDM participation, satisfaction with TDM consultation, difficulties in TDM, and medical and demographic information. RESULTS: Half (55%) reported a treatment choice: 33% wanted the choice to be their own, 59% wanted to share and 8% wanted to delegate the decision. Only age predicted participation preference with older women preferring a more passive role. Eighty percent of women participated as much as, 13% more than and 6% less than desired. Adjusted for age, women reporting PC had fewer difficulties in TDM (beta = 0.21, p = 0.009) than women not reporting PC, while over-involved women had more doubts about their choice (beta = -0.23, p = 0.005). PC was associated with being offered a treatment option (chi2 = 15.59, p < 0.001) and surgeons expressing a surgical preference (chi2 = 6.63, p = 0.036). Satisfaction was unrelated to PC. CONCLUSION: Most Chinese women want shared TDM and to know their surgeon's treatment preference. Over-involved women are at greater risk of difficulties and doubts in TDM and under-involved women perceive a lack of time and information to make their decision.

The development and validation of a knowledge, attitude and behaviour questionnaire to assess undergraduate evidence-based practice teaching and learning.

OBJECTIVES: Most evidence-based practice (EBP) educational assessment tools evaluated to date have focused on specific knowledge components or technical skills. Other important potential barriers to the adoption of EBP, such as attitudinal, perceptual and behavioural factors, have yet to be studied, especially in the undergraduate setting. Therefore, we developed and validated a knowledge, attitude and behaviour questionnaire designed to evaluate EBP teaching and learning in an undergraduate medical curriculum. METHODS: We derived the questionnaire from a comprehensive literature review, informed by international and local experts and a Year 5 student focus group. We determined its factor structure and refined and validated the questionnaire according to the responses of a cohort of Year 5 and a combined group of Years 2 and 3 students using principal components factor analysis with varimax rotation. Factor reliability was computed using Cronbach's alpha coefficient. We assessed construct validity by correlating the factors with other measures of EBP activity and examined responsiveness through paired t-test of the pre/post factor mean scores. RESULTS: A 43-item questionnaire was developed. Four factors were identified from both student groups. The overall questionnaire as well as each factor had high construct validity (Cronbach's alpha > 0.7 for each scale). No significant correlations were found between the 4 factors, confirming their orthogonality. Positive correlations, however, resulted between factor mean scores and other EBP activities. The responsiveness of the questionnaire was satisfactory. CONCLUSION: A reliable knowledge, attitude and behaviour measure of EBP teaching and learning appropriate for undergraduate medical education has been developed and validated.

Voluntary HIV antibody testing amongst youth in Hong Kong.

We performed a study to estimate the prevalence of and factors associated with human immunodeficiency virus (HIV) antibody-testing behaviour among youth in Hong Kong. It was a population-based cross-sectional study. Questions on HIV testing were asked as part of a youth sexuality study conducted in July to December 1996 among young adults in Hong Kong. A total of 517 (53.6%) males and 447 (46.4%) females aged 17 to 28 years completed an anonymous structured self-administered questionnaire. Respondents had good knowledge about correct modes of HIV transmission and prevention. 9.4% (95% confidence interval [CI]: 7.0, 12.3) of males and 6.4% (95% CI: 4.3, 9.1) of females had been tested for HIV through blood donation. Excluding blood donation, 3.7% (95% CI: 2.2, 5.7) of males and 3.6% (95% CI: 2.1, 5.9) of females had been tested (voluntary testing). 47.5% (95% CI: 44.4, 50.7) of subjects reported at least one major risk factor for HIV infection. In multivariate analyses, factors independently associated with both voluntary HIV testing and HIV testing by blood donation were age and having had sex with multiple partners. A higher educational level was a predictor of HIV testing by blood donation. Self-assessment of having sufficient sex education was also significantly associated with voluntary HIV testing. HIV testing is not widespread in Hong Kong and those at risk are more likely to have been tested. It is of concern, however, that many of those reporting risk factors have not been tested.

Physicians' attitudes towards the computerization of clinical practice in Hong Kong: a population study.

OBJECTIVE: To identify the prevailing attitudes among physicians to use of computers in the clinical setting and specifically those attitudes that may be associated with the adoption of computers in practice. DESIGN: A self-completed, 20-question postal questionnaire sent to 4850 randomly selected physicians. The questionnaire focused on details of the physicians' practice; actual computerization of or intention to computerize clinical and administrative functions; attitudes towards computerization; self-perceived computer ability and knowledge; and demographic information. The attitude statements were grouped under four themes according to a factor analysis. RESULTS: The survey was completed by 897 physicians. Only physicians in 'individual' practices were included in the analysis. This group was further dichotomized into clinical users (those with one or more clinical functions computerized) and non-clinical users. Non-clinical users were older and had fewer specialist qualifications. Although there was strong support for the attitude statements among both groups with regard to the benefit of computerization to patient care, there was much less support for electronic medical records. Non-clinical users were concerned about the potentially negative impact of computerization on the clinical encounter and the perceived high cost of computerization. DISCUSSION: The attitudes among current clinical users and non-users were substantially different. The most important disincentives to computerization were the potential for interference with the patient-physician encounter and the cost of computerizing multiple practice locations. Turning these disincentives into opportunities for change remains the challenge.

The development and evaluation of an integrated community-based, patient-centred learning activity at the University of Hong Kong.

OBJECTIVE: To develop and evaluate the Patient Care Project (PCP), an integrated patient-centred, community-based learning activity, implemented at the University of Hong Kong since 1992. DESIGN: The PCP, a required course in the first 2 preclinical years, is structured into four learning cycles over 9 months. Each cycle consists of a patient interview followed by a debriefing group tutorial. In-depth interviews with the same patient allow students to explore the impact of disease and patients' illness experience, as well as the contribution of the wider determinants of health to their condition. The debriefing tutorial frames empirical observations into theoretical models and its format reinforces habits of problem-based learning. The programme was evaluated using survey questionnaires completed by students, patients and tutors. PARTICIPANTS: 324 first- and second-year medical students. RESULTS: Students, participating patients and tutors all rated the PCP positively in end-of-course evaluations. Specifically, 68% of students commented that the PCP had met all or most of its stated objectives, while there was nearly unanimous agreement among patients that students demonstrated understanding and empathy in the visits and interviews. Tutor appraisal of student performance also indicated the attainment of all stated aims and objectives overall. CONCLUSIONS: The PCP is a valuable contribution to community-based learning and the promotion of the patient-centred clinical method.

Patterns of cigarette smoking, alcohol use and other substance use among Chinese university students in Hong Kong.

The pattern of tobacco, alcohol, and other substance use was assessed among 1,197 Chinese undergraduates in Hong Kong. Students reported their current and past use of tobacco (13%), alcohol (61%), marijuana (2%), and other illicit drugs (0.4%). Perceptions of risk from the use of different substances were low among those who use substances and among senior students. The rate of substance use was higher among males, residents of university hall, senior students, and among those who possessed a positive attitude towards substance use. There were significant associations between different substance uses among the respondents.

Risk factors for sexually transmitted diseases and casual sex among Chinese patients attending sexually transmitted disease clinics in Hong Kong.

BACKGROUND: The risk factors for sexually transmitted diseases (STDs) and having casual sex among the Chinese people are unknown. GOAL: The goal of the study was to estimate the prevalence of STDs and to develop a profile of risk behavior among patients attending STD clinics in Hong Kong. STUDY DESIGN: In a clinic-based, cross-sectional study, 448 patients attending two government STD clinics were randomly sampled and interviewed by means of a structured questionnaire. RESULTS: The prevalence of STDs was 51% (70% of men and 35% of women). Attendees who had STDs diagnosed were more likely to be male, never married, and smokers and alcohol users (ever) and to have had casual sex or sex during travel with someone not their usual partner. Those who did not always use condoms were more likely to be male and never married. Having had casual sex was reported by 63% of the respondents. Those who reported having had casual sexual encounters were more likely to have the following characteristics: male; never married; no religious belief; ever smoker and alcohol user; current STD; had sex during travel; history of STD; inconsistent condom user; and perception of being at low risk for STD. After adjustment, only male gender was associated with casual sexual encounters. CONCLUSION: The results of this study indicated several risk factors among Chinese patients for the acquisition of STDs, for not using condoms, and for having casual sex. This information is useful in strengthening and evaluating currently available STD prevention and control strategies for the Chinese population in Hong Kong and elsewhere.
