A well-constructed study plan is the backbone of any clinical research project. It guides the research process and ensures that the study is feasible, ethical, and capable of generating valid results. Here’s a step-by-step guide to developing an effective study plan.
The core of your study plan is the research question. It must be specific and significant and address an unresolved issue. For example, “Can we diminish loneliness among the elderly by providing a structured in-home support program?” This question is precise and has direct implications for improving patient care.
Could you conduct a thorough literature review to understand what is already known?
Define the significance of the research question and its potential impact on clinical practice or public health.
2. Study Design:
Choose between observational and clinical trials based on the research question and available resources.
Consider various designs, such as cross-sectional, cohort, or case-control studies for observational research and randomised controlled intervention trials.
3. Participants:
Define explicit inclusion and exclusion criteria to ensure a representative sample.
Estimate the required sample size early to avoid feasibility issues later.
4. Variables:
Clearly define predictor, confounding, and outcome variables.
Ensure these variables are measurable and relevant to the research question.
5. Statistical Issues:
Formulate hypotheses and determine the appropriate statistical methods.
Plan for data analysis to ensure the results are valid and reliable.
Expertise in your study area is crucial. Keep abreast of recent advances and engage with the scientific community through:
Systematic literature reviews.
Participation in scientific meetings and conferences.
Building relationships with other experts in the field.
Ethical standards are paramount in clinical research. Ensure your study:
Obtains informed consent from participants.
Maintains participant confidentiality.
Receives approval from relevant ethical committees.
Throughout the study, remain open to new ideas and improvements:
Attend conferences and engage in informal discussions with peers.
Be receptive to feedback and willing to refine your study plan as necessary.
Developing a robust study plan involves meticulous preparation and continuous learning. By focusing on a well-defined research question and adhering to ethical standards, you can ensure that your clinical research will be feasible, impactful, and valuable to the scientific community.

Estimating the total cost of a clinical trial before it runs is challenging. Public data on past trial costs can be hard to come by, as many companies guard this information carefully. Trials in high income countries and low and middle income countries have very different costs. Clinical trial costs are not normally distributed.[1] I took a dataset of just over 10,000 US-funded trials. You can see that the range is huge, from small device or behavioural trials costing as little as $50,000, while large multi-centre international trials can cost hundreds of millions.
Guest post by Safeer Khan, Lecturer at Department of Pharmaceutical Sciences, Government College University, Lahore, Pakistan Introduction The success of clinical studies relies heavily on proper financial planning and budgeting. These processes directly impact key factors such as project timelines, resource allocation, and compliance with regulatory requirements. The accurate forecasting of costs for clinical trials, however, is a highly complex and resource-intensive process. A study by the Tufts Center for the Study of Drug Development found that the average cost of developing a new drug is approximately $2.
Guest post by Safeer Khan, Lecturer at Department of Pharmaceutical Sciences, Government College University, Lahore, Pakistan Introduction Recent years have seen a substantial rise in oncology clinical trials, with annual growth exceeding 260 studies on average [1]. Despite this increase, these studies continue to be some of the most demanding and resource-intensive in clinical research. The combination of intensive monitoring, detailed assessment schedules, and highly specific eligibility criteria creates substantial operational challenges.
