Survey Design and Analysis for Health Research

Transforming Health Data into Actionable Insights

In clinical research, public health, and epidemiology, surveys play a crucial role in gathering real-world evidence (RWE) and patient-reported outcomes (PROs). However, effective survey-based research requires meticulous design, validated instruments, and robust analytical methods to ensure accuracy, reliability, and scientific validity.

At Clievi, we specialize in end-to-end survey design and data analysis services, helping researchers, healthcare organizations, and pharmaceutical companies develop and analyze high-quality survey data for evidence-based decision-making.

Our Comprehensive Survey Research Services

1. Survey Design and Development

A well-designed survey minimizes bias and enhances data accuracy. We assist in:

• Defining research objectives and key variables for health-related surveys.
• Developing structured questionnaires with appropriate question formats (Likert scales, multiple-choice, open-ended, etc.).
• Ensuring validity and reliability through pre-testing and cognitive interviews.
• Adopting validated health survey instruments such as:
  • SF-36 (Short Form Health Survey)
  • EQ-5D (EuroQol Health Questionnaire)
  • PROMIS (Patient-Reported Outcomes Measurement Information System)
  • WHOQOL (WHO Quality of Life Survey)

2. Target Population and Sampling Strategy

Accurate sampling ensures that findings are representative. We help in:

• Identifying target demographics, patient groups, or healthcare professionals.
• Determining appropriate sample size using power calculations.
• Employing probability and non-probability sampling techniques (random sampling, stratified sampling, snowball sampling).

3. Data Collection Methods and Implementation

We assist in selecting the most effective survey administration method:

• Online surveys (Qualtrics, REDCap, Google Forms, SurveyMonkey, etc.)
• Telephone and in-person interviews
• Paper-based surveys for hospital or clinical settings
• Mobile health (mHealth) surveys for real-time patient feedback
• Electronic patient-reported outcomes (ePRO) tools

4. Ethical Considerations and Regulatory Compliance

We ensure surveys comply with:

• Ethical approval and Institutional Review Board (IRB) requirements.
• GDPR and HIPAA data protection regulations for handling patient data.
• Informed consent procedures to protect participant rights.

5. Data Cleaning and Preprocessing

We perform rigorous data validation and cleaning to enhance data quality:

• Handling missing data and outliers.
• Standardizing responses for consistency.
• De-identifying patient data to maintain confidentiality.

6. Statistical Analysis and Interpretation

Once data is collected, our team conducts advanced statistical analysis using:

• Descriptive statistics (mean, median, standard deviation, prevalence rates).
• Inferential statistics (t-tests, chi-square tests, ANOVA, regression analysis).
• Multivariate modeling (logistic regression, survival analysis, structural equation modeling).
• Machine learning techniques for predictive analytics.
• Textual and qualitative analysis (Thematic coding, NVivo, ATLAS.ti) for open-ended responses.

7. Visualization and Reporting of Survey Findings

We provide:

• Interactive dashboards and visualizations (Tableau, Power BI, R Shiny).
• Infographics and summary reports for easy data interpretation.
• Manuscripts, white papers, and conference presentations to disseminate findings.
