The Chronic Disease Co-Care (CDCC) Pilot Scheme is initiated for early screening and management of people with hypertension (HT), pre-diabetes mellitus (pre-DM) and diabetes mellitus (DM) in Hong Kong. This study will evaluate the quality of care, feasibility, acceptability, effectiveness and cost-effectiveness of the Scheme.
This is a 12-month cohort study among the District Health Centre (DHC) or DHC Express, healthcare providers, CDCC participants and a comparison group of 1,886 non-participants. All the person-in charge, 2 family doctors and 1 of each allied health provider from each DHC/DHC Express will be administered with the questionnaires on quality of care and costing. All CDCC participants will be included in subject characteristics, among which a convenience sample of 548 will complete a telephone survey on experience, enablement and satisfaction of the CDCC Pilot Scheme. The health outcomes of 1,886 CDCC participants and 1,886 non-participants will be compared for evaluation of effectiveness and cost-effectiveness.
Participant characteristics, enablement, compliance to the standards of care, and costing of CDCC Pilot Scheme will be summarized using descriptive statistics. Differences in the proportion of patients meeting treatment targeted for HT, pre-DM and DM after 12 months will be compared by chi-squared test and logistic regressions. The incremental cost-effectiveness ratio will be evaluated by comparing with the World Health Organization (WHO) threshold. This study will inform future healthcare planning and policy for manpower and resource allocation.
This study aims to evaluate the quality of care, feasibility, acceptability, effectiveness and cost-effectiveness of the CDCC Pilot Scheme in Hong Kong. The objectives of this study are the following:
The detailed study design of each objective are:
Objective (a): All participants in CDCC Pilot Scheme between 1 Jan 2024 and 30 Jun 2024 will be included in the evaluation. The characteristics including demographics, comorbidities, and medications of the participants will be summarized using descriptive statistics.
Objective (b): For the evaluation of the structure of care, quantitative data will be collected through structured questionnaires on the quality of care with DHC/DHC Express managers at 6 months and repeated at 12 months. Each DHC/DHC Express will also nominate two family doctors and one of each network allied health professionals (optometrists, podiatrists, dietitians, and physiotherapists subject to the availability in each center) within their service network to complete the questionnaire at 12 months. For the evaluation of the standards on process and outcome of care, all participants in the CDCC Pilot Scheme between 1 Jan 2024 and 30 Jun 2024 will be included.
Objective (c): Participants will be conveniently sampled after completion of the Health Risk Factor Assessment (HRFA) at DHC/DHC Express between 1 Jan 2024 and 31 Mar 2024 to complete surveys on self-reported outcomes. For the first survey at 3 months, a questionnaire will be used to assess participants' enablement level and experience during the screening phase. The second follow-up survey will be administered at 12 months to assess participants' experience in clinical encounters.
Objective (d): This will be a 1-year comparative cohort study including CDCC and non-CDCC participants to evaluate the effectiveness of the CDCC Pilot Scheme. A total of 264 CDCC participants, and 264 non-CDCC participants screened positive for HT, pre-DM, or DM will be included as intervention and comparison group, respectively. All participants will be followed up 12 months. Records for CDCC participants who meet the inclusion criteria between 1 Jan 2024 and 30 Apr 2024, will be extracted from the Electronic Health Record Sharing System database. Meanwhile, a convenient sample of 1,886 non-CDCC participants (comparison group) will be recruited from the community between 1 Jan 2024 and 30 Apr 2024.
Objective (e): This will be a 1-year comparative cohort study including CDCC and non-CDCC participants to evaluate the costs and cost-effectiveness of the CDCC Pilot Scheme. The total costs incurred on the CDCC Pilot Scheme from 1st January 2024 to 31st December 2024, including set-up costs, ongoing operational costs and ongoing administrative and maintenance costs will be collected via questionnaires. Direct medical costs for CDCC participants and non-CDCC participants will be collected after 12 months.

For categorical variables, frequency and proportion will be used. | Characteristics of CDCC participants will be described at baseline |
| Healthcare providers' adherence to care standards on the evaluation framework by the quality of care questionnaire | The standards (proportion of participants) achieved by the program in each of the criterion specified under each domain of quality of care according to the CDCC Pilot Scheme protocol. The questionnaire is developed based on the evaluation framework on structure, process and outcome. The percentage of adherence out of 100% based on pre-determined key performance indicators will be reported. A higher score means a greater adherence to the standards of care. | Questionnaires will be implemented at 6 months and 12 months after the study begins |
