Cross-Sectional Study on Attitudes among General Practitioners towards Pneumococcal Vaccination for Middle-Aged and Elderly Population in Hong Kong

Objective

To study the attitudes among general practitioners towards pneumococcal vaccination for middle-aged (50–64) and elderly population (over 65) in Hong Kong and the factors affecting their decision to advise pneumococcal vaccination for those age groups.

Design

Cross-sectional study of general practitioners in private practice in Hong Kong.

Participants

Members of Hong Kong Medical Association delivering general practice services in private sector.

Measuring Tool

Self-administered questionnaire.

Main Outcome Measures

Intention to recommend pneumococcal vaccination, barriers against pneumococcal vaccination.

Results

53.4% of the respondents would actively recommend pneumococcal vaccination to elderly patients but only 18.8% would recommend for middle-aged patients. Consultation not related to pneumococcal vaccine was the main reason for not recommending pneumococcal vaccine (43.6%). Rarity of pneumonia in their daily practice was another reason with 68.4% of respondents attending five or less patients with pneumonia each year. In multivariate analysis, factors such as respondents would get vaccination when reaching age 50 (OR_m 10.1), and attending 6 pneumonia cases or more per year (OR_m 2.28) were found to be associated with increasing likelihood for recommending vaccination to the middle-aged. While concerns of marketing a product (OR_m 0.41), consultation not related to vaccination (OR_m 0.45) and limited time (OR_m 0.38) were factors that reduced the likelihood.

Conclusion

Public policy is needed to increase the awareness of impact of pneumococcal pneumonia and the availability of preventive measures.     

Two new species of Spadicoides from Brunei and Hong Kong

Spadicoides hodgkissa sp. nov. and Spadicoides arengae sp. nov., recorded from submerged decaying wood in Hong Kong and from decaying palm fronds in Brunei, are described and illustrated. Spadicoides hodgkissa is characterized by versicolored, obovoid conidia with up to 2 septa, including a distal distoseptum and a proximal euseptum, while Spadicoides arengae is characterized by unicellular, ellipsoidal conidia with verruculose walls that are relatively large. Eight genera, including Dendrographium, Helminthosporium, Luzfridiella, Paliphora, Polyschema, Polytretophora, Porosubramaniania, and Weufia, have the same conidiogenesis as Spadicoides. A key to these genera is provided.     

Prevalence of Mental Illness among Homeless People in Hong Kong

MetholodogyThis study examined the prevalence and correlates of mental illness in homeless people in Hong Kong and explored the barriers preventing their access to health care. Ninety-seven Cantonese-speaking Chinese who were homeless during the study period were selected at random from the records of the three organisations serving the homeless population. The response rate was 69%. Seventeen subjects could not give valid consent due to their poor mental state, so their responses were excluded from the data analysis. A psychiatrist administered the Structured Clinical Interview for DSM-IV Axis-I disorders (SCID-I) and the Mini -Mental State Examination. Consensus diagnoses for subjects who could not complete the SCID-I were established by three independent psychiatrists.FindingsThe point prevalence of mental illness was 56%. Seventy-one percent of the subjects had a lifetime history of mental illness, 30% had a mood disorder, 25% had an alcohol use disorder, 25% had a substance use disorder, 10% had a psychotic disorder, 10% had an anxiety disorder and 6% had dementia. Forty-one percent of the subjects with mental illness had undergone a previous psychiatric assessment. Only 13% of the subjects with mental illness were receiving psychiatric care at the time of interview. The prevalence of psychotic disorders, dementia and the rate of under treatment are hugely underestimated, as a significant proportion (18%) of the subjects initially selected were too ill to give consent to join the study.ConclusionThe low treatment rate and the presence of this severely ill and unreached group of homeless people reflect the fact that the current mode of service delivery is failing to support the most severely ill homeless individuals.     

Variations in problem conceptualizations and intended solutions among Hong Kong students

Cognitive schema were used to explain health and illness behaviors among Chinese students. University students in Hong Kong were asked to attribute causes and suggest solutions to five health/mental health problems: Weakness/Fatigue, Tension/ Anxiety, Sleep Difficulty, Hollow/Emptiness, and Headache. The patterns of endorsement on the causal and solution categories used for the five problems were compared using a new asymptotic chi-squared test. The response patterns were found to be significantly different across the five problems. Each problem was attributed to multiple causes including psychological, social, situational, somatic, and existential factors. The intended solutions were often related to the nature of the causal attributions especially when the problems were mild. In lay help-seeking, the Hong Kong students would attempt a variety of self-help measures. However, for professional consultation, the medical doctor would be the primary care professional the students would turn to for most of the problems except in the case of Hollow/Emptiness.     

Social Determinants of Health Information Seeking among Chinese Adults in Hong Kong

Background

Health communication inequalities were observed in Western population but less is known about them among the Chinese. We investigated health information seeking behaviours and its social determinants among Chinese adults in Hong Kong.

Methods

Probability-based sample surveys over telephone were conducted in 2009, 2010/11 and 2012 to monitor family health and information use. Frequency of health information seeking from television, radio, newspapers/magazines and Internet were recorded and dichotomised as ≥1 time/month and <1 time/month (reference). Logistic regression was used to yield adjusted odds ratios (aOR) of health information seeking for different demographic characteristics, socioeconomic status (education, employment and income), chronic disease and behaviours (smoking, drinking and physical activity).

Results

Among 4553 subjects in all surveys, most (85.1%) had sought health information monthly from newspapers/magazines (66.2%), television (61.4%), radio (35.6%) or Internet (33.2%). Overall, being male, lower education attainment, lower household income, ever-smoking and physical inactivity were associated with less frequent health information seeking (all P <0.05). Compared with younger people, older people were less likely to search health information from Internet but more like to obtain it from radio (both P for trend <0.001). Having chronic diseases was associated with frequent health information seeking from television (aOR  =  1.25, 95% CI: 1.07–1.47) and Internet (aOR  =  1.46, 95% CI: 1.24–1.73).

Conclusions

This study has provided the first evidence on health information inequalities from a non-Western population with advanced mass media and Internet penetration. Socioeconomic inequalities and behavioural clustering of health information seeking suggested more resources are needed for improving health communication in disadvantage groups.     

Perceptions and uses of Chinese medicine among the chinese in Hong Kong

The present paper was based on both qualitative observations and quantitative survey data. Major findings are as follows: (1) The sacred or magical-religious tradition of Chinese medicine is accepted by a relatively small portion (roughly one-fifth) of the ordinary Chinese people in urban Hong Kong, and is relatively more popular among women or less educated people. (2) Both the classical-professional and the local-empirical traditions of secular medicine are resorted to by many Chinese people (over one half) either for treating diseases or for strengthening their constitution. The acceptance of secular Chinese medicine does not vary significantly among different sex, age, education, or income groups. It should be noted that secular Chinese medicine is often used in addition to or in combination with modern Western medicine. (3) It appears that most people are more confident in the Chinese medical tradition than in Chinese-style practitioners in Hong Kong, and that people's confidence in secular Chinese medicine has been increasing in recent years. (4) There are reasons for the confidence in secular Chinese medicine. Chinese medicine is generally perceived to be better than or as good as Western, scientific medicine in some ways, such as for tonic care, for fewer side effects, for curing the cause (not symptoms) of diseases, and for treating certain diseases. Therefore, to ordinary Chinese people, Chinese and Western medicine may perform either equivalent or complementary functions. (5) As regards the process of seeking medical care, most people seem to follow the pattern of moving from self-medication, using Chinese and/or Western home remedies, to Western-style doctors, to Chinese-style practitioners, and finally to a Western medical hospital. Policy and theoretical implications of these findings are discussed.
