• Base line survey revealed that the treatment for
  chronic bronchial asthma is irrational and cost
  of therapy is high compared to Standard Treatment
  Guidelines (STG).
• A prospective, randomized controlled study was
  designed to study the impact of two consecutive
  face-to-face educational intervention for
  prescribers on prescribing behaviour and cost of
  therapy in bronchial asthma.
• After first intervention, 6 prescriptions were
  according to STG After second intervention,
  again 6 prescriptions were according to STG,
  though 9 of the prescriptions had steroid
  inhalations but other medicines differed from
  STG. In control facility none of the
  prescriptions was according to STG.
• Cost of treatment in both the control and
  intervention facilities was significantly higher
  as compared to the treatment given according to
  STG. Cost of treatment given by pooled
  procurement of medicines is statistically less as
  compared to the same medicines purchased from the
  retailers.

BACKGROUND

• Cost of irrational drug use is enormous in terms
  of limited resources and adverse clinical
  consequences. Chronic common illnesses, like
  bronchial asthma and hypertension are an economic
  burden to the country.
• Baseline survey done, revealed that 98 and 3 of
  the prescriptions for mild hypertension and for
  chronic bronchial asthma respectively were
  according to STGs in colony hospital (Secondary
  health care facility) of Delhi.
• Qualitative assessment of prescribers behaviour
  revealed that misconception for treatment of
  bronchial asthma is a major cause of irrational
  prescribing.
• Hence, a face-to-face educational intervention
  study was conducted.

AIMS OF THE STUDY

• Impact of two consecutive educational
  intervention on prescribing behaviour of doctors
  for bronchial asthma treatment in colony
  hospital.
• Effect of change in prescribing behaviour, if
  any, after intervention on cost of therapy in
  bronchial asthma.

STUDY DESIGN

• A prospective randomized controlled study of
  prescription monitoring from the outpatient
  department of two public colony hospitals.

SAMPLE SIZE

• Prescribers of two colony hospitals, intervention
  and control.
• 100 prescriptions of patients who were on
  maintenance therapy for bronchial asthma at each
  health facility.

5
METHODS

• Two colony hospitals who had shown in baseline
  survey irrational prescription were chosen, in
  one, educational intervention was done and other
  acted as control.
• A training programme (face-to-face educational
  intervention) was done for prescribers of one
  colony hospital at respiratory medicine
  department of a tertiary care hospital.
• STGs for treatment of bronchial asthma, patient
  education and proper use of inhalers were
  discussed. Published literature was given.
• STGs for chronic bronchial asthma Regular use
  of inhaled corticosteroid, like Budesonide,
  Flutiacasone or Beclomethasone (400-1600 ?g) as
  per severity of disease. Use of bronchodilater
  (salbutamol) as and when required.

6
METHODS Contd.

• After one month of training, hundred
  prescriptions of chronic bronchial asthma from
  OPD of colony hospitals (intervention and
  control) were monitored using the same performa
  as was used for base line survey (characteristics
  of the patient, diagnosis, no. of drugs
  prescribed, their name, dose, duration and route
  of administration).
• For re-enforcement, a second, similar training
  programme for the same prescribers was done after
  a gap of 3 months.
• After one month of the second training programme,
  100 prescriptions were monitored as before, from
  both the health facilities.

RESULTS

• All completed performas were computed with regard
  to number of drugs prescribed, drugs from EDL and
  cost of 14 days treatment at the rate at which
  the public facility is procuring medicines
  (pooled procurement).
• 14 days estimated cost of therapy according to
  STG was calculated for each patient at pooled
  procurement rate.
• 14 days cost of therapy for each patient was also
  calculated at retail/market price.

CONCLUSIONS

• This study has shown that even though the
  prescribers are prescribing from EDL, their
  prescriptions for chronic bronchial asthma are
  irrational.
• Two face-to-face educational training programmes
  have changed the prescribing behaviour to a small
  extent in the treatment of bronchial asthma.
• Pooled procurement system of purchasing medicines
  is very economical and money saved can be used to
  purchase more essential drugs.
• Recommendations
• Another mode of intervention e.g. managerial or
  regulatory may also be used along with
  educational intervention to change the
  prescribing behaviour of doctors for the
  treatment of bronchial asthma.
• Corticosteroid inhalers should be included in
  essential drug list and made available for all
  public facilities.
