Background

Latin word audire meaning “to hear “. Started way back in Persia (522-486 BC), China, Egypt, Greece. Auditors in Britain in medieval times, used to hear the accounts read out to them and written records followed soon after. Audit is hence “hearing the data to” verify transactions to prevent fraud, to detect errors

Audit was thus used random method to check the data for errors. Audit in every industry has changed from finding faults to establishing some standards and audit compliance with

Audit is a standard practice in

  • Finance and accounts
  • Airline industry
  • Quality
  • Performance
  • Project
  • Energy
  • Information technology
  • Operations audit
  • Forensic audit

Health Care Audit

  • King Hammurabi, the sixth king of Babylon in 1750 BC! Instigated the audit for clinicians
  • Florence Nightingale, detailed statistical analysis in 1853 to 1855, reducing mortality from 40–2%
  • Ernest Codman from Harvard, in 1916, Ortho Surgeon, Surgical outcomes
  • Avedis Donabedian in 1966, conceptual model of clinical audit.

What is the difference between audit and research?

AuditResearch
Are we doing, what we should be doingAre we doing, what we should be doing
Guidelines or standards already in placeSet the standards ( new knowledge)
Sometimes what is common senseTo discover better ways of doing

Are they completely different?

  • Often Audit is needed as first part of research
  • Sometimes one needs to research to get the data for audit
  • Audit is easier to complete and present and publish
  • Research is easier when one has experience of audits

Areas of Clinical Audit: Avedis Donabedian

  • Resources: Waiting times
  • Process: Infection prevention, bed sore prevention etc
  • Outcome: Most clinical studies

What is not clinical audit

  • Review of mortality of one patient in a meeting
  • Knee jerk reaction to mortality and morbidity and changing practice
  • Looking at the outcome in a non systematic manner.

Who should (Should not?)

Medical Audit to Clinical Audit

Audit was formally introduced into the NHS in 1989 via the Working for Patients White Paper, called Medical Audit

Nurses and other health care professionals started getting involved and hence the term changed to Clinical Audit

National clinical audits in UK are now mandatory.

Who should not?

  • If I audit my work, then I understand all the compounding factors
  • If I do not audit my work, someone else would audit and tell me what to do
  • Professional is someone who constantly strives to improve his work and takes accountability

Why doctor should do clinical audit?

Reasons to do clinical audit

  • Many ways to skin a cat, which method should I follow
  • Want to make the treatment better for my patient
  • Have to answer my patient questions and concerns
  • Should do it, otherwise someone else will tell me what to do

Need not do?

  • Follow standard guidelines and protocols
  • My patients are doing well in my practice
  • Base my practice on what learned seniors and peers advice
  • Can answer all the questions, patients and relatives ask

How to do Clinical audit

  • Method 1: Follow standard practice, Protocol approach and audit compliance
  • Method 2: Local Trigger initiating clinical Audit with a systematic approach

Method 1

  • Look out for protocols which are already accepted and implement them locally where we work
  • For example, Safe Surgery Check list, Use of Ultrasound for CVC, marking the site and side of the patient for surgery,
  • Audit compliance of the same regularly and change practice to ensure compliance.

Method 2

Use of triggers for audits locally

A Scenario 1

We saw failures at six weeks after a fracture surgery so we decided to look at all patients with this surgery over a period of time. Reviewed over 300 X rays, 33% of patients had problems with this particular technique.

It was decided to change our practice to different accepted surgical technique. Review of X rays of the different surgical technique showed 5% problems

A Scenario 2

82 year old lady with fracture neck of femur, Diabetic keto acidosis, Sepsis. Operated but died on the third post op day

Discussed in the audit meeting

  • Review all fracture neck of femur patients treated at kauvery hospital
  • Over 80 years of age I.e octogenarians
  • Our mortality rate was well below the reported incidence in the literature 5% as opposed to 6 to 9.6 %

Some practical example

1. The trigger: Valium given instead of Voveran for a patient

Action

Medical Council of India code of medical ethics says “Every physician should prescribe drugs with generic names legibly and preferably in capital letters”

A simple trigger

  • One of the patients presented with back pain
  • X rays and clinical exam was normal
  • He was treated with standard analgesia and physio
  • He returned with ongoing pain, and more importantly with night pain

A simple analysis of data

  • His investigations showed him to have secondaries from lung tumor
  • Do not want to miss any red flag signs
  • But we have limited time to take history in a busy clinic

Change in practice

Beta version

The current one

Change in practice saves time (and potentially Life). But needs re-analyzing the data for accuracy

2. The Trigger: Blood is being cross matched, but not used. Time and money cost

Group and save vs Cross matching

# neck of femur IT type#neck of femur Intra capsular type
Blood loss was higherBlood loss was lower
Post op Hb was lowerPost op Hb drop was not high
Transfusion need was higherTransfusion need was lower
Transfusion index was usedTransfusion index was used
X matching doneGroup and save done

*Cost and time savings achieved

3. The trigger

  • A female (Nurse) patient with back pain was sent for an X ray
  • Patient was not asked if she could be pregnant prior to these investigations

Action

Atomic Energy Regulatory Board of Government of India

A permanent radiation warning symbol and instructions for pregnant/likely to be pregnant women shall be pasted on the entrance door of the X-ray installation, illustrating that the equipment emitsx-radiation.

4. The trigger

  • We prescribe pain relief to be given as needed
  • Nurse mentions that the patient is comfortable after surgery, but patient had wept due to pain in the night

Action

KMC Speciality pain audit

  • Used Knowledge and attitude to pain questionnaire among health care professionals by using a standard validated questionnaire
  • Found out that there is general lack of understanding patients pain
  • Pain assessment score chart was introduced based on patients perception and rather than the perception of the health care professional.

Change in the way pain is monitored

5. The trigger

  • Patient was quite depressed in the ward
  • Psychiatrist opined Post trauma stress syndrome

Action

Literature review

  • Post-Traumatic stress disorder: An under-diagnosed and under-treated entity. January 2013”

Audit: Analysis of all patients with major trauma identified many with PTSS with a standard questionnaire, this was administered by a social worker

Findings: Significant number of major trauma patients were found to be depressed.

Change in practice

  • Psychiatrist advice is sought for major trauma and poly trauma patients
  • This will also is a starting point of research in this area

6. The Trigger: Not all patients who had undergone partial hip replacement were happy with their hip replacement

Action

Literature and guidelines

  • Total hip replacement gives better functional results than partial hip replacement
  • But there is a risk of postoperative dislocation as a complication

Change in practice

  • Total hip replacements were introduced at Kauvery hospitals, Trichy
  • The case cohort were studied for complications and satisfaction
  • Over 110 patients who had total hip replacements were reviewed
  • Their mortality, morbidity especially the dislocation rate were reviewed
  • It was found out that the total hip was safe even in the elderly population.
  • It is routinely offered for our patients

7. The trigger

  • Quite a few patients and the relatives do not consent for total knee replacement
  • Even though this would make their quality of life better
  • They mention the age in particular for not undergoing the procedure

Action

Literature review and audit

  • Quite a number of papers in the literature to support this surgery in the elderly population
  • Outcome Audit: We reviewed 50 patients over the age of 70 who had undergone TKR and shown that the mortality was nil and morbidity noted could be managed by other departments effectively

Change in practice

  • We are able to counsel patients accordingly
  • We seek opinion of other consultants promptly to ensure optimal outcome

8. The Trigger

  • Quite a few patients were supplemented with Vitamin D for Musculo skeletal pain
  • This practice was questionable when there was a different diagnosis for many patients which needed a definitive treatment

Action

Literature review

  • Vitamin D deficiency can give symptoms of non specific body and bone pain
  • Vitamin D deficiency leads to muscle weakness which makes function of joints difficult

Audit

  • Vitamin D testing was performed on a case cohort of patients who had presented with non specific pain, difficulty in getting up from sitting posture, weakness, tiredness with body pain
  • It was found quite a significant number of patients were deficient and insufficient, a small percentage with hypervitaminosis D
  • These patients were treated with vitamin D replacement only and patients showed noticeable improvement

Change in practice

  • Vitamin D testing more commonly used
  • Vitamin D is now used for treatment more often
  • Sit to stand test is now routinely used in Orthopaedic clinical examination as it detects proximal myopathy

9. The trigger

  • Aunt of a doctor who had total knee replacement, In post op pain, felt that she should not have undergone this procedure
  • Was on epidural analgesia for pain relief, but still!

Action

Literature review and Audit

  • Peri articular injection of analgesia was practiced in US and Australia
  • There were many papers to justify this
  • An audit was performed studying epidural group and showed unsatisfied patients with inadequate pain relief.

Change of practice

  • PIA is routinely used instead of epidural analgesia
  • Consistent pain relief and satisfaction is noted
  • The audit cycle was completed.

10. Trigger: Frozen shoulder is a common problem

Physiotherapy does not help all the patients shoulder arthroscopy is quite interventional and poor acceptance by patients. MUA and injection helps and audit of all patients with good results.

Action

How to audit deaths

Mortality

  • Mortality review for individual deaths has limited learning value
  • Mortality is a crude outcome indicator
  • Has multiple compounding factors in most cases
  • Individual patient mortality is best done as a confidential enquiry, Eg CEPOD

Change in practice

  • All patients with fracture neck of femur are offered surgery
  • Pre-op optimisation and early surgery
  • Immediate post op mobilization
  • Not kept in ICU unless warranted

Certainly Audit can change practice for betterment of patients

  • At all our kauvery units clinical audit meeting was started way back in 2009 and should continue
  • Change is the constant Mantra
  • But with systematic analysis, which is what is Clinical Audit and that is how it should be done

When should I do clinical audit

  • As a medical student
  • As an intern
  • As a practicing doctor
  • As a health care professional

We are in the business of treating patients

  • All Clinical Audits should start with patients in mind
  • what does the patient want?
  • Ideas, Concerns and Expectations of the patient is a start
  • I don’t want to die
  • I don’t want to stay in ICU
  • I do not want any complications
  • Will there be lot of pain
  • will I walk normally like I used to.

Where should I do clinical audit

  • Outpatients
  • In patients
  • Operating Theatres
  • Emergency department
  • Treatment rooms
  • Para clinical areas
  • Non clinical areas which will impact on clinical satisfaction.

Summary

Use Triggers to start clinical audit in your area of responsibility and practice

The trigger

  • Children with fracture lower limbs, stayed in the hospital longer, cost and family difficulties noted
  • Though children were treated in plaster casts, traction and major surgery when they had fractured thigh bones
  • Newer techniques were standard in major institutions to
    1. Reduce the hospital stay,
    2. Reduce the cost to the hospital and the family and
    3. Improve the outcome

Change in practice

  • The thigh bone fractures were stabilized with Minimally invasive surgery resulting in better outcome
  • This was shown by comparing the traditional methods of treatment with a different technique of acceptable treatment
  • This changed our practice locally.

Audit can change practice across a country

  • Elderly patients with fracture neck of femur were developing bed sores
  • The patients with fracture neck of femur patients were waiting in trolleys for a long period in Emergency department
  • Time delay for admission from emergency department to hospital bed was stipulated to less than 4 hr across the country.
