  1. Components of health services research projects August 18, 2004 Jose Suaya, MD, MBA, MPH Funder/project name etc info.

  2. Source • Designing and conducting health system research projects • Corlien Varkevisser • IDRC (Canada) & WHO

  3. Background • Part of the health system: set of cultural beliefs about health and illness that provide the basis for health seeking and health promoting behavior

  4. Health system • 1-The individual, family and community • 2-The health care services: public and private sector • 3-Health-related sectors

  5. Health services research • It is problem oriented: • Concentrate on those factors that help to explain/solve a problem under examination

  6. Types of problems/concerns • Policy: Role of government/MOH • Administration and management: monitoring and evaluation procedures • Direct services: access, acceptability, appropriateness, coverage, quality, cost, effectiveness • Individual: social/psychological/physical needs ; families

  7. Stages • I- Statement of the problem • II- Objectives of the study • III- Methodology • IV- Pilot study • V- Work plan • VI- Administration • VII- Monitoring • VIII- Budget Justification • IX- Deliverables

  8. Stage I: Statement of the problem • Identification of the problem for research • Analysis of the problem • Formulation of the statement of the problem

  9. Stage II: Objectives of the study • Literature Review • Objectives: • General • Specific • Title of the study

  10. Stage III: Methodology -a • Selection, definition, and operationalization of the variables • Outcome of interest • Exposure or intervention • Confounders

  11. Stage III: Methodology -b Study design • Non-interventional studies (observational) • Exploratory • Cross sectional • Follow-up (cohort) • Case control • Interventional studies • Experiment • Quasi-experiment

  12. Goal of the study • To obtain: • Valid: true conclusions • Reliable: same method, same circumstances, same results

  13. Threats to validity • Confounders • History • Differential loss • Hawthorne effect

  14. Stage III: Methodology -c Data collection techniques • Use of available data • Observation: watching and recording behavior • Interviews • Written questionnaires • Focus groups discussions • Combination of the above

  15. Stage III: Methodology -d Sampling • Non Probabilistic • Convenience • Quota • Probabilistic • Simple random sample • Systematic • Cluster sampling • Multistage

  16. Stage III: Methodology -e Sample Size • Desirable • Expected value (expected proportion) • Margin error for the estimate • Precision (e.g. 95%) • Feasible • Cases, human, time, money

  17. Stage III: Methodology -f Data Collection and Data Handling • What • How • By whom • When • Sequence • Quality control

  18. Stage III: Methodology -g Data Compilation • Software • Data base development • Coding • Data entry • Verification and Validation • Programming

  19. Stage III: Methodology -h Data Analysis • Plan for data analysis • Univariate • Bivariate • Multivariate • Graphical representation

  20. Stage IV: Pilot Study • Helps to identify potential problems in methodology and logistics

  21. Stage V: Workplan • Workload: tasks, duration, and person responsible for each of the activities • Time schedule (Gantt): describe graphically the order and the duration for each of the activities

  22. Stage VI: Administration • Human • Material • Financial • Logistical resources • Accountability

  23. Stage VII: Monitoring • Ongoing process of checking implementation of the project: • Track of resources used • Number and quality of tasks completed

  24. Stage VIII: Budget Justification • Starting from the working plan, identify the resources needed for each activity and calculate the unit cost and total cost

  25. Stage IX: Deliverables • Progress Reports • Scientific • Financial • Final Report/ Publishable Papers
