Integrated thyroid disorder module in pharmacology curriculum

Introduction Conventionally, undergraduate MBBS education in India has been organized into separate disciplines taught across the different phases of the curriculum. Basic science subjects taught during the 1st year focus on the structure and normal functioning of the human body, followed by subjects dealing with the pathological basis of disease and pharmacological management, while clinical subjects are largely reserved for the later years. Although this sequential pattern is intended to gradually build a foundation for clinical understanding, students often find it difficult to appreciate the practical relevance of the concepts being taught at earlier stages. This compartmentalized nature of subject-wise teaching frequently reduces learner engagement and continuity of understanding. This fragmented approach also results in considerable repetition. Faculty members in later phases often need to revisit previously taught concepts before introducing advanced topics, consuming valuable teaching time. Similar overlap may occur across multiple subjects, leading to redundancy and inefficient utilization of curricular hours.[1] Integrated teaching modules across the full course have emerged as an effective strategy to overcome these limitations. It promotes meaningful connections among subjects and presents medical knowledge in a more clinically relevant and learner-centered manner. Recognizing its importance, the competency-based medical education curriculum introduced in India in 2019 incorporated integration as a key educational principle and making six modules as mandatory. Since the human body itself functions as an integrated system, teaching subjects in isolation may hinder the development of holistic understanding. Integrated learning helps students perceive diseases and organ systems as unified concepts rather than disconnected fragments of information, for example, thyroid disorders.[2,3] Both horizontal and vertical integration are essential to ensure continuity between basic sciences and clinical application. Such alignment strengthens the biological basis of disease understanding while encouraging a comprehensive approach to patient care. Pharmacology naturally intersects with anatomy, biochemistry, physiology, pathology, community medicine, general medicine, and several other disciplines. Although individual teachers may occasionally incorporate related concepts during routine lectures, these efforts are often isolated and not co-ordinated across departments. In a structured integrated module, however, all relevant departments collaboratively contribute to the planning and delivery of competencies related to a particular disease or system, ensuring coherence and shared educational goals. For pharmacology teaching integration must be seen as great opportunity to apply the learnt concepts as pharmacology is considered a bridge between normal (physiology) and clinical sciences like medicine. An important principle of integration is that it should be competency-driven rather than teacher-driven. The focus must remain on achieving learning objectives and improving student understanding, rather than merely combining teaching sessions from different departments. The example of an integrated module on thyroid disorders illustrates how coordinated teaching can effectively connect concepts across disciplines and enhance meaningful learning. Integrated Module Development Successful implementation of an integrated module requires effective academic coordination and collaborative planning. A designated module coordinator or team leader should oversee the development, execution, and evaluation of the integrated program. The integration team should comprise faculty members from all the disciplines contributing relevant competencies or learning objectives related to the selected topic. The process can be understood using thyroid disorders as an example, particularly to illustrate the contribution of pharmacology within an integrated framework. The initial step involves identifying competencies and learning objectives from different subjects that can be meaningfully connected. Faculty members then engage in collaborative discussions and brainstorming sessions to determine the content suitable for inclusion in the module. Once the objectives are finalized, appropriate teaching–learning methods are selected, and sessions are distributed across large group teaching, small group discussions, case-based learning, or other instructional formats. Another important component is deciding the type of integration to be adopted, such as sharing, nesting, or correlation. Lead departments are identified for specific sessions to ensure coordination, communication among participating departments, and smooth conduct of the integrated activities. These integrated sessions are subsequently incorporated into the annual academic timetable. Sessions may be conducted by one faculty member or jointly by teachers from multiple departments; however, the essential aspect is that all involved departments collaboratively plan the teaching activity, irrespective of who ultimately delivers the session. In the thyroid disorder module, pharmacology assumes a leading role during a Phase II large group teaching session, where selected competencies from anatomy, biochemistry, physiology, community medicine, and medicine are incorporated through the nesting model of integration [Figures 1 and 2]. In this approach, the primary subject addresses certain learning objectives of related disciplines within its teaching session, while all participating departments remain informed and coordinated regarding the shared content.[4]Figure 1: Example of integrated module on thyroid disorders in Phase 1 and 2 of MBBS curriculumFigure 2: Example of integrated module on thyroid disorders in Phase 3 of MBBS curriculumFor Phase II small group teaching, a “linker case” strategy is used to integrate competencies from pharmacology and medicine. This reflects the correlation model of integration, where a clinical case introduced in one phase is progressively expanded in later phases with additional clinical details and learning objectives. Such cases create continuity across the disciplines and phases of training. Linker case discussions are particularly useful for revisiting concepts from normal anatomy, biochemistry, physiology, community medicine, and pathology while simultaneously connecting them with clinical management. Multiple cases may also be incorporated depending on the scope of competencies being addressed.[5,6] In Phase III, medicine becomes the lead discipline for selected thyroid disorder sessions. Here, the sharing model of integration is applied because several competencies overlap between subjects [Figure 3]. This method reduces duplication of content, optimizes teaching time, and prevents unnecessary repetition by allowing one department to comprehensively address shared concepts.Figure 3: Methods of integration showing nesting (a), correlation (b) and sharing (c)Despite the emphasis on integration, it is essential that phase-specific competencies and learning objectives remain the primary focus within each stage of training. Integration is feasible only for selected topics, while other subjects may require alignment rather than full integration. Alignment refers to synchronizing related topics from different disciplines within the same academic period – for example, teaching thyroid disorders topics concurrently in pharmacology, pathology, and microbiology. Topics that are unsuitable for integration or alignment should still receive adequate dedicated teaching time and may continue as parallel sessions within the curriculum. Reflections At the completion of an integrated module within a phase, students participate in a dedicated session for feedback and reflection writing in logbooks, usually conducted over approximately 1 h. Learner reflections provide valuable insights into the effectiveness of the module and help identify areas for further improvement. Assessment strategies are also aligned with the principles of integrated teaching, ensuring that integrated topics are represented in both formative and summative examinations. In the recent CBME 2024 revision, integrated topics have gained greater emphasis, with one complete examination question specifically dedicated to integrated learning areas. These themes have also been standardized across medical colleges in India to maintain uniformity in undergraduate medical training. Benefits of Integrated Modules Integrated teaching offers several educational advantages: Reduces unnecessary overlap and repetition between subjects Encourages learning within a clinical and practical context making it more student centred Promotes meaningful, relevant, and application-oriented understanding Facilitates linkage of concepts across different phases of the curriculum Improves long-term retention of knowledge Enhances collaboration, communication, and coordination among faculty members across departments. In fact many meet for first time even when working in same institutes for many years. Challenges in Implementation Like any major curricular reform, integrated teaching also faces several practical challenges, which may vary across institutions and regions. The commonly encountered barriers include:[1,6] Limited motivation or willingness to adopt change Inadequate administrative or leadership support like Principal office Constraints related to infrastructure and logistics like meeting places Lack of awareness on integration Lack of integrated modules. Despite these challenges, integrated teaching reflects the natural way in which medical knowledge and patient care are interconnected. Learning medicine through integration is much like enjoying a well-prepared biryani – its essence lies in the harmonious blending of all ingredients together, rather than experiencing each component separately in isolation.
