Benefits and limitations of implementing Chronic Care Model (CCM) in primary care programs: a systematic review
Background:
Chronic Care Model (CCM) has been developed to improve patients' health care by restructuring health systems in a multidimensional manner. This systematic review aims to summarize and analyse programs specifically designed and conducted for the fulfilment of multiple CCM components. We have focused on programs targeting diabetes mellitus, hypertension and cardiovascular disease.
Method and results:
This review was based on a comprehensive literature search of articles in the PubMed database that reported clinical outcomes. We included a total of 25 eligible articles. Evidence of improvement in medical outcomes and the compliance of patients with medical treatment were reported in 18 and 14 studies, respectively. Two studies demonstrated a reduction of the medical burden in terms of health service utilization, and another two studies reported the effectiveness of the programs in reducing the risk of heart failure and other cardiovascular diseases. However, CCMs were still restricted by limited academic robustness and social constraints when they were implemented in primary care. Higher professional recognition, tighter system collaborations and increased financial support may be necessary to overcome the limitations of, and barriers to CCM implementation.
Conclusion:
This review has identified the benefits of implementing CCM, and recommended suggestions for the future development of CCM

Household characteristics and influenza vaccination uptake in the community-dwelling elderly: a cross-sectional study
Elderly people are at higher risk of influenza diseases. The morbidity benefit of vaccination is often offset by its low and variable coverage in elderly people in the community.
To assess household and individual factors associated with influenza vaccination uptake in the community-dwelling elderly of age ≥65, data from a cross-sectional Thematic Household Survey conducted in 2011/12 in Hong Kong were analysed, using vaccination in the past 12 months as the outcome variable. Households comprising an elderly person living with non-elderly member(s) of age ≤64 were also evaluated. Data fields included socio-demographics, household structures, health status, eligibility to financial subsidy, and subscription to health insurance.
The influenza vaccination rate was 27% in 4204 elderly persons from 3224 households. Being male, being economically active, attaining primary education, having smoking behaviours were negatively associated with vaccination, while chronic illness and age ≥70 were positively associated factors. Elderly people living alone gave a variable rate of vaccination ranging from 16.4% in males of age 65–69 to 36.3% in females ≥70. Household size per se was not associated with vaccination, but a positive correlation could be seen if the household was composed of vaccinated non-elderly member(s).
Influenza vaccination uptake in the community-dwelling elderly is dependent on both individual and household characteristics, the latter including the influence of vaccinated non-elderly member(s). The low vaccination coverage of “younger” (age 65–69) elderly men living alone is particularly worrisome. Interventions focusing on vulnerable elderly people and their social networks would be desirable
Perspective from health professionals on delivery of sub-acute care in Hong Kong: A qualitative study in a health system
Objectives The perception and understanding of health professionals of the role of sub-acute care in the health system will have an impact on the potential effectiveness in preventing unnecessary hospitalization. This study aims to explore the perceived role and quality of sub-acute care services in the context of Hong Kong from the perspective of health service providers and to identify barriers to effectiveness.Methods Seven focus groups were conducted and the discussion was led by a guide covering three main areas: definition/component/role of sub-acute, difficulties in the sub-acute care services provision, and suggestion for further improvement in the provision of sub-acute care.Results The participants highlighted the positive role of sub-acute to promote patient's health and quality of life so as to reduce unnecessary hospitalization. The potential barriers in the sub-acute care identified were interrelated and focused mainly on systemic issues including lack of service coordination, specialist input and resources. The participants also suggested a number of practical ways to improve the quality of sub-acute care services.Conclusions The findings showed a need for further improvement in the process of sub-acute care by developing operation guideline and re-evaluating the allocation of resources to support the sub-acute care provision.Sub-acute care Communication barrier Health professionals Healthcare system
Primary care physicians' response to pandemic influenza in Hong Kong: A mixed quantitative and qualitative study
Objectives: The current study was conducted to use a developed framework to appraise the public primary care response to pandemic 2009 influenza A H1N1 virus in Hong Kong in 2009. Methods: A cross-sectional survey was conducted of 300 doctors working in public primary care clinics. In addition, a qualitative study was conducted in two selected general outpatient clinics (GOPCs) with 10 doctors between September and December 2009. Results: We found that there was an increase in clinical service demand for public primary care doctors and that there was lower compliance with hand washing as compared to the wearing of masks among GOPC doctors during the study period. Conclusions: Since hand hygiene and influenza vaccination are effective methods to prevent the spread of influenza infection, future studies should explore the reasons for non-compliance with these preventive behaviors among doctors. More education and training in dealing with influenza A H1N1 infection may be needed. © 2012 International Society for Infectious Diseases.link_to_subscribed_fulltex
Acceptance of the COVID-19 vaccine based on the health belief model: A population-based survey in Hong Kong
BACKGROUND: Vaccines for COVID-19 are anticipated to be available by 2021. Vaccine uptake rate is a crucial determinant for herd immunity. We examined factors associated with acceptance of vaccine based on (1). constructs of the Health Belief Model (HBM), (2). trust in the healthcare system, new vaccine platforms and manufacturers, and (3). self-reported health outcomes.
METHODS: A population-based, random telephone survey was performed during the peak of the third wave of COVID-19 outbreak (27/07/2020 to 27/08/2020) in Hong Kong. All adults aged ≥ 18 years were eligible. The survey included sociodemographic details; self-report health conditions; trust scales; and self-reported health outcomes. Multivariable regression analyses were applied to examine independent associations. The primary outcome is the acceptance of the COVID-19 vaccine.RESULTS: We conducted 1200 successful telephone interviews (response rate 55%). The overall vaccine acceptance rate after adjustment for population distribution was 37.2% (95% C.I. 34.5–39.9%). The projected acceptance rates exhibited a “J-shaped” pattern with age, with higher rates among young adults (18–24 years), then increased linearly with age. Multivariable regression analyses revealed that perceived severity, perceived benefits of the vaccine, cues to action, self-reported health outcomes, and trust in healthcare system or vaccine manufacturers were positive correlates of acceptance; whilst perceived access barriers and harm were negative correlates. Remarkably, perceived susceptibility to infection carried no significant association, whereas recommendation from Government (aOR = 10.2, 95% C.I. 6.54 to 15.9, p < 0.001) was as the strongest driving factor for acceptance. Other key obstacles of acceptance included lack of confidence on newer vaccine platforms (43.4%) and manufacturers without track record (52.2%), which are of particular relevance to the current context.CONCLUSIONS:
Governmental recommendation is an important driver, whereas perceived susceptibility is not associated with acceptance of COVID-19 vaccine. These HBM constructs and independent predictors inform evidence-based formulation and implementation of vaccination strategies
Association between antipsychotic use and acute ischemic heart disease in women but not in men: a retrospective cohort study of over one million primary care patients
Background:
Research comparing sex differences in the effects of antipsychotic medications on acute ischemic heart disease (IHD) is limited and the findings ambiguous. This study aimed to investigate these associations within a primary care setting.
Methods:
Hong Kong public general outpatient electronic records of patients aged 45+ during 2007–2010 were extracted, with the last consultation date as the baseline for a 4-year follow-up period to observe acute IHD hospitalizations (2011–2014). Antipsychotic use was defined as any prescription over the previous 12 months from a list of 16 antipsychotics, while acute IHD was defined by ICD-9: 410.00–411.89. Both sex-specific and sex-combined (both sexes) mixed-effects Cox models (random intercept across 74 clinics) were implemented to examine the association and test the interaction between antipsychotics and sex.
Results:
Among 1,043,236 included patients, 17,780 (1.7%) were prescribed antipsychotics, and 8342 (0.8%) developed IHD. In sex-specific analyses, antipsychotic prescription was associated with a 32% increased hazard rate of acute IHD among women (95% CI 1.05–1.67) but not among men. A likelihood ratio test comparing sex-combined models with and without the interaction between antipsychotic use and sex suggested significant interaction (χ2 = 4.72, P = 0.030). The association between antipsychotic use and IHD among women attenuated and became non-significant when haloperidol was omitted from the operationalization of antipsychotic use (HR = 1.23, 95% CI 0.95–1.60).
Conclusion:
Our results suggest that antipsychotic prescription is moderately associated with an increased risk of acute IHD among women in primary care and this relationship may be explained by specific antipsychotics. Further research should observe and capture the potential intermediary mechanisms and the dose-response relationship of this association to provide more rigorous evidence to establish causality and inform clinical practices
