Scientific title
A prospective observational cohort project to assess the feasibility of a prevention program for cardiovascular diseases in the context of a private health insurance in rural Nigeria (QUICK-I) plus the development and evaluation of a patient centred cardiovascular health education program for patients in rural Nigeria: from an exploration of stakeholders perspectives towards practical tools (QUICK-II)
Acronym
QUICK-I + QUICK-II
Study hypothesis
Please note that under this record, two protocols are contained (but both part of the same trial). The first protocol, QUICK-I, is an observational cohort study to assess the feasibility of a prevention program for cardiovascular disease in rural Nigeria, whilst the second protocol, QUICK-II, is a two-part protocol that involves a qualitative study design for the development of a tailored cardiovascular health education program (CHEP) (part 1), and a prospective observational cohort study using repeated measurements for an evaluation of treatment adherence (part 2). The anticipated trial dates for each part of the trial are as follows:
QUICK-I:
Anticipated start date: 11/06/2010
Anticipated end date: 11/11/2011
QUICK-II:
Anticipated start date: 11/03/2011
Anticipated end date: 11/12/2012
Furthermore, the target number of participants for each protocol are as follows:
QUICK-I: 300 patients
QUICK-II: 150 patients
All other differences for each protocol can be found under the relevant section with the subtitles for each protocol (QUICK-I or QUICK-II).
QUICK-I:
The implementation of a cardiovascular disease (CVD) prevention program, based on international guidelines, is feasible in patients at risk for development of CVD in the context of a private health insurance in rural Nigeria.
QUICK-II:
The addition of a tailored cardiovascular health education program (CHEP) will lead to better treatment adherence in hypertensive patients who participate in a cardiovascular disease prevention program in rural Nigeria.

Intervention
QUICK-I:
Observational research. In a rural clinic in Nigeria, participating in the Hygeia Community Health Plan insurance scheme, 300 patients at risk for development of CVD (patients with hypertension, diabetes, renal disease or established CVD) will be prospectively followed for one year. Patients will be treated for CVD risk factors (e.g. antihypertensive treatment, treatment for diabetes, treatment for dyslipidaemia) according to international guidelines. Data on test results, treatment regimes and treatment outcomes will be collected. Costs of the program will be estimated using costs data from the clinic and the insurance company with additional World Health Organization data. After one year of follow up for each patient, treatment will be continued (all treatment is standard CVD care) but data collection will end.
QUICK-II:
Patient centered cardiovascular health education program. The project consists of two parts:
1. The development of CHEP
2. The evaluation of CHEP
Part 1 will consist of four phases. First, interviews will be conducted to make a qualitative assessment of how key stakeholders perceive the nature and the management of risk factors for CVD. The interviews will be done with patients at risk for CVD visiting the participating clinic, health care professionals (HCP) and with the staff of the health insurance company. Second, the interview data from patients will be used for the development of CHEP. Third, the interview data from health care professionals will be used to identify supportive strategies that are needed for the implementation of CHEP. Fourth, these supportive strategies will be implemented (e.g. training health professionals).
The second part of the project will evaluate the effect of CHEP through a prospective hospital based project. Using a pre-post design, this project will assess the effect of CHEP on adherence to therapy (primary outcome) and a number of secondary outcomes e.g. blood pressure (BP) control. Measurements will be conducted prior to CHEP (baseline) and 6 months thereafter in a subset of patients included in the CVD prevention project (QUICK 1) those with uncontrolled hypertension after eight months of treatment. Case file data, and interview data with health care professionals in the participating clinic will be used to evaluate the feasibility of the application of CHEP in practice.
Part 1 (development of CHEP) is planned for the first 8 months. After inclusion, patients will receive the intervention (CHEP): 3 sessions during 12 weeks. After the intervention, patients will be followed for a maximum of 6 months. The total duration of follow up per patient is therefore maximum 9 months.

Primary outcome measures
QUICK-I:
1. The adjusted cardiovascular care quality score based on the United Kingdom National Health Services Quality and Outcome framework (NHS QOF) after the implementation of the CVD prevention program
2. The range of possible costs of CVD prevention treatment per patient per year, divided per category (treatment, consultation etc):
2.1. For the insurance company considering the current benefit package
2.2. For the hospital
2.3. For the patient
2.4. Costs outside the scope of this particular insurance program (for example costs when using different benefit packages/treatment regimes)
3. The estimated resources required for CVD prevention per year related to the total yearly medical pay out of the insurance company
4. The estimated net health care costs of a CVD prevention program per quality adjusted life year gained in a community health insurance setting
All primary endpoints are assessed after completion of follow up of the entire cohort (the last patient is estimated to complete follow up 1.5 years after inclusion of the first patient). Assessment is estimated to be completed 6 months after completion of the cohort follow up time.
QUICK-II:
Part 1:
Development of CHEP. This will be completed after completion of the follow up period of the QUICK-I cohort (estimated 1.5 years after inclusion of the first patient in QUICK-I).
Part 2:
Level of adherence to medication at 6 months after the implementation of CHEP minus level of adherence to medication at baseline as measured by the 8 item Morisky adherence scale. The primary endpoint will be assessed after completion of the follow up period of the entire QUICK-II cohort. This is estimated to be one year after the inclusion of the first patient in the QUICK-II cohort.
Secondary outcome measures
QUICK-I:
1. The proportion of patients in whom CVD risk factor treatment is successful at one year of follow up. In addition, the proportion of patients successfully treated will be determined per risk factor.
2. Description of characteristics of responders to treatment and non responders to treatment after one year of follow up
3. The proportion of patients with target organ damage at baseline and at one year of follow up
4. The proportion of patients with CVD at baseline and at one year of follow up (new and recurrent CVD events)
5. Incidence of all cause mortality in the project population during one year of follow up
6. Score on the 12-item short form health survey (SF-12) quality of life questionnaire at baseline and after one year of follow up
7. Score on the 8-item Morisky Medication Adherence Scale at three, six, nine months and one year of follow up
8. The proportion of patients who report side effects during one year of follow up and description of the most frequent reported side effects of CVD preventive drugs during one year of follow up
9. The association between baseline serum creatine kinase (CK) and the reduction in blood pressure after drug treatment at 6 months and one year of follow up
10. The association between the changes in blood pressure after drug treatment and the changes in serum CK at 1 year of follow up compared to baseline
All secondary endpoints are assessed after completion of follow up of the entire QUICK-I cohort (the last patient is estimated to complete follow up 1.5 years after inclusion of the first patient). Assessment is estimated to be completed 6 months after completion of the cohort follow up time.
QUICK-II:
Part 2 only, measured at 6 months after baseline:
1. Changes with respect to physiological measures systolic blood pressure, diastolic blood pressure, and body mass index (BMI)
2. Changes in other factors that may influence patients' hypertension management
3. The presence of self-reported additional cardiovascular risk factors (physical activity, diet, smoking, alcohol, sodium intake)
4. Knowledge of hypertension and hypertension management
5. Perceptions of hypertension
6. Perceptions of medication
7. Self efficacy
8. Experienced stress
9. Patient satisfaction with the delivered care within QUICK-I (e.g. doctors' performance, supply of medication, frequency of follow up, satisfaction with CHEP)
All secondary endpoints will be assessed after completion of the follow up period of the entire QUICK-II cohort. This is estimated to be one year after the inclusion of the first patient in the QUICK-II cohort.
