ARTI (Antibiotics and Respiratory Tract Infections):linking academia to primary care practice

Antibiotics and Respiratory Tract Infections

RTIs: acute otitis media

sinusitis, cold

sore throat (tonsillitis, laryngitis)

acute cough (bronchitis, pneumonia)

Mostly viral and self-limiting

Effects of antibiotics are limited

Over-prescription of antibiotics• resistance• patients’ re-consultation• unnecessary exposure to adverse effects• unnecessary costs

Antibiotics in The Netherlands

Comparatively low antibiotic consumption (coinciding with low resistance)

450 treatments / 1000 inhabitants / year France: x3, Greece: x5

No OTC selling

80% is prescribed by general practitioners

► 4 primary care guidelines for treatment of RTIs antibiotics indicated for patients: with a severe RTI

with risks of complications

(suspected of) pneumonia

How does it work in daily practice?

diagnostic uncertainty

ARTI 1: insight in antibiotic prescribing

Methods: detailed analysis of 2800 consultations for RTIs

ARTI 1: Results

Antibiotic prescription for RTIs: 37% of consultations

prescription over-prescription

OMA 47% 5%

sore throat 30% 58%

sinusitis, cold 35% 53%

acute cough 38% 48%

44% of prescriptions are not according to the guidelines:

over-prescription is

▪ highest for tonsillitis and bronchitis

▪ associated with - inflammations signs

- patients’ wish for an antibiotic

ARTI 2 and 3:interventions to optimise antibiotic prescribing

ARTI 2: RCT

intervention: ▪ education GPs (practice level)

guidelines, literature, communication

▪ monitoring/feedback prescribing data and behaviour

▪ information material patients

outcome: -12% in antibiotic prescribing rate

ARTI 3: CBA

similar intervention: ▪ education to larger groups of GPs

▪ monitoring/feedback prescribing data

outcome: no reduction in number of antibiotic prescriptions

Implementation: ARTI 4

Antibiotic prescribing practice can be improved

Barriers in implementation: - commitment of physicians

- sustainability of the effect

embedment within a regular quality assurance cycle:

practice accreditation* of the Dutch College of General Practitioners

* improving quality in care and organisational structure of primary care practices

3 years cycle: - yearly audit

- practice organisation

- prescribing routines

- chronic disease management

- yearly ‘improvement plans’

ARTI 4: support and a ready-to-use plan

optimising Ab prescription for RTIs

reducing (chronic) use of PPIs

ARTI 4: Study set-up (I)

• RCT with 87 primary care practices (1-7 GPs / practice)

• Ab and PPI practices serve as each others controls

• Primary outcomes:

Antibiotics: Ab prescriptions / 1000 pnts / year

% 2nd choice prescriptions

J01 collected via pharmacies

• Secondary outcomes and feed-back supplied to practices:

Antibiotics: prescribing behaviour

4-weeks registration of RTIs

• Data collection: 1 year preceding intervention, at year 1 and 2

ARTI 4 study set-up (II)

Multiple intervention

• educational meeting GPs at practice level

- guidelines, literature

- feedback on prescription data / behaviour

- communication, patients’ pressure

• improvement plan

ARTI4 intervention significantly reduces antibiotic prescription

Goals and future plans:

• long-term effectiveness of this intervention (2 years)• development of internet-based educational programs
