TEACHING LEARNING METHODS

The following strategy is used for organizing teaching learning activities:

a)       Lectures are used for teaching the basic principles for 4th semester students of surgery viz. infection, wound healing, shock, trauma.

b)       Integrated seminars are utilized during the 6th and 8th semester for teaching system based surgery viz. thyroid and endocrine disorders, GIT, urinary, head and neck and vascular disorders.

c)        Clinical teaching to a group of 12 students on surgical Inpatient Wards and OPD’s.

d)       Clinical skill training- We teach basic surgical skills to our final year students and interns in minor OT, casualty theatre and main theatre. In the department we also organize yearly workshop on suturing & knot tying where students get an opportunity to acquire hands-on experience on these important skills.

Guidelines for students posted in Department of Surgery 3rd – 4th Semester

This is the first introductory posting in surgery to provide orientation, towards the general functioning of the Department and the nature of clinical work performed in the Department of surgery. You will be posted in the surgical Out-patients department. This is a five weeks posting. The learning objectives for this session are to learn :

  • the art and science of history taking,
  • general evaluation of overall health;
  • basic principles of examination of a lump;
  • examination of hernia, hydrocoele and abdomen;
  • examination of breast;
  • examination of head and neck;
  • evaluation of wounds, ulcers and sinuses.

You will be required to attend the surgical Out-patient clinic from 9.15 A.M. to 12.00 noon. Be punctual as any person coming to clinic after 9.30 A.M. will be marked absent. Attendance register will be sent to the Dean.

You are required to be properly dressed, wear a white coat, with a name plate (no jeans and no sneaker shoes please!). You are required to bring the following:-

A pen torch with metal tip, measuring tape, Vernier callipers, stethoscope, patella hammer;

Please read “ Norman Browse- An Introduction to the symptoms and signs surgical diseases” or “Hamilton Bailey- Physical signs”, in order to acquire theoretical background of clinical examination. A book by “ S.Das ” has many mistakes, and therefore, not recommended.

5th Semester

The learning objectives for this session are honing the skills of physical examination. You are again posted in the Out-patient surgical department. The timings are 9.15 A.M. to 12.00 A.M.. Attendance is compulsory. For this semester utilize your time in examining as many patients as possible. Visit the consultation rooms of all the consultants and senior registrars. Remember there is no substitute for seeing the patients.

You cannot acquire the practical skills by sitting in the Library.

A famous physician of USA, Sir William Osler said” To study the phenomena of disease without books is to sail an uncharted sea whilst to study books without patients is not to go to sea at all”

Besides seeing patients you should also acquire the following basic surgical skills- wound dressing, debridement , abscess aspiration and drainage, excision biopsy of skin lesions, lipoma and epidermal cysts, skin suturing and knot tying, proctoscopy, rubber banding of piles.

Please attend minor surgical operation theatre situated at the end of the surgical OPD corridor to acquire the above skills. Please maintain a record of cases seen and surgical skills learnt in a diary/log book. You will be assessed on this.

Assessment of III – V Semesters

A weightage of 15 marks for III semester and 25 marks for IV & V semester will be given in the form of viva questions with short case presentations.

6th Semester

The learning objectives in the 6th semester are to master the skills of surgical diagnostic evaluation. You are advised to follow a problem based approach (PBL).

Greet the patient cheerfully with a smile and introduce yourself. Seek patient’s permission for

interrogation and examination (e.g. “ I am________ , a 6th semester student of MBBS. Can I ask a few

questions about your illness and can I examine you. This will help me in learning the diagnosis and in becoming a good doctor so that I may serve the society well). Be extremely polite in your approach. If patient refuses simply thank him and go to a next one. Ask presenting symptoms along with duration.

Formulate a diagnostic hypothesis (e) based on the patient’s age, gender, place of living and initial symptoms. This is essentially a list of differential diagnoses. Think about pros and cons of each possibility.

Now ask details of the present and past history focused on the initial diagnostic hypothesis. For example-in a patient with bleeding P/R at age 40. If you have consider piles and cancer rectum as your diagnostic hypothesis, your interrogation should revolve around these two conditions with the objective of proving one and refuting the other.

After interrogation revise your diagnostic hypothesis(e) on the basis of historical facts. Perform a quick general exam and make a note of overall health status.

The next step is to carry out a detailed physical exam of the lump, swelling or ulcer. Remember no exam of a swelling or ulcer is complete without checking the draining lymph nodes.

Make a diagrammatic representation of your findings with colour felt pens on your diary/log book. Go through the following checklist while seeing any lump: number, site, size, shape, margin , surface, skin over it, structures superficial and deep to it, temperature over it, tenderness, consistency, transillumination, thrill or bruit and the regional nodes.

Once again revise your diagnostic hypothesis. Generate a diagnostic workup plan (Diagnostic decisions).

Allocation of Units

Find which unit you are posted with? The first 12 students of the batch go with Surgical Unit 1 and Unit 3, while the remaining students are posted with Unit 2 and Unit4. Reverse this order during the 8th semester posting.

You will get 3 beds allotted to you. You are responsible for seeing all the patients admitted to these beds during your stay of 6 week with us. Record the history, exam findings and results of any investigations.

Assessment: OSCE = 12 marks with 3 clinical skills stations. Portfolio= 5 marks. Total=17 marks. Note these marks are added in the final MBBS exam result.

8th Semester Posting: This is again 6 weeks long posting on surgical wards. The learning objectives of this final session is to develop the competency in making a diagnosis, generating a diagnostic decision plan and outlining the therapeutic decision. During this period you have to accompany the patient to the operation theatre, assist in the operation, write postoperative orders and follow the postoperative recovery of the case. Write down the daily progress in your case records till the patient is discharged.

Perform dressings, I.V. line insertion, catheter and nasogastric tube insertion on your cases.

Assessment: OSCE= 13 marks with 3 clinical skills stations, diary/log book= 5 marks, Total =18 marks.

Objectives of Clinical Training

At the end of clinical posting in surgery, a student should be able to:

  • Elicit a detailed & relevant history
  • Carry out a physical examination
  • Identify patients’ problems
  • Reach a differential diagnosis
  • Formulate appropriate investigations
  • Interpret the results of investigations

Practical / Clinical Assessment:

Long Case, Short Case, Objective Structured Clinical Examination (OSCE)

Notes on OSCE

Objective Structured Clinical Examination (OSCE) has proved to be a valid, reliable and objective modality of assessment for assessing clinical skills. This involves breaking up clinical competence in to a series of clinical skills (history taking, performing physical examination, interpreting lab data, differential diagnosis, treatment & follow up), and testing each skill in a separate ‘station’. Each station is provided with a real or simulated patient, mannequin, equipment, X-Ray, or even a question which should be tackled by a student within a prescribed time limit say, 2 – 5 minutes, on rotation basis. The performance is observed by an observer using a predetermined check list for assigning marks. A detailed discussion on the preparation of OSCE is beyond the scope of this book. However, a few tips have been given for initial introduction.

Principles of Designing OSCE Define skill to be tested

  • Break into steps
  • 3-5 minutes to perform each task
  • Observation by examiner

Scoring based on vital components of skill and precautions to be observed

  • Provision for negative score, if necessary

Two types :Procedure stations (needs observer) and Question stations Skills that can be tested using OSCE

  • History taking
  • Physical examination
  • Analysis of clinical data
    • Observation and ability to recognize disease patterns
    • Interpretation of investigations
    • Performance of a procedure

–          Diagnostic

–          Therapeutic

  • Problem solving skill
  • Communication skill
  • Others

–           Surgical/clinical instruments

–           Surgical specimens

–          Procedures on models/dummy

–          Patient education
