Result

Follow up

Baker et al, 1997

[66]

Leicester, UK

Audit on all long-term users (> 4 weeks) in the medical centre then GPs received either: 1 = feedback on prescribing practices + criteria for the management of long term BZ users. 2 = feedback + criteria + reminder cards for patient files.

RT

18 practices patients = 2409 long term BZ users

Both groups changed after intervention with respect to levels of compliance to criteria. 8.2% of patients were stopped and 1.3% were decreasing BZs. No difference between groups.

2nd audit completed 1 year post intervention

Holden et al, 1994 [67]

Liverpool, Southport - UK

Audit of BZ use + GPs invited to 2 meetings on auditing BZ use in general practice. Individual practices determined their own BZ policy for prescribing and reducing use.

Observational

15 practices, 3234 patients

Overall reduction of 16%. Sig reduction in those <65 (25%) compared to those >65 = 12%.

2nd audit at 8 months (end of study)

Pimlott et al, 2003 [68]

Canada - Ontario

1 = audit and feedback on GPs prescribing of BZs compared to peers and best practice + information sheet on BZs every 2 months for 6 months.

2 = Control group had the same intervention for antihypertensives.

RCT

168 GPs (intervention) 206 GPs (control)

No sig decrease in BZ prescribing and no sig difference between intervention and control groups.

6 months post intervention

Study Design and Size

Result

Follow up

McClaugherty, 1997 [69]

Texas

LTC pharmacist audited BZ use + gave feedback to nurses and doctors. Nurses were given sleep promoting guidelines. OT's & physio's were encouraged to increase activities for those who couldn't sleep.

Quasi-Experimental

10 Nursing Homes, 3 Texas counties

% of patients prescribed routine BZ decreased from 4.5% (baseline) to 1.6% (post intervention). % of patients prescribed BZ on an as needed basis increased from 7.9% (baseline) to 9.3% (post intervention)

3 months post intervention

Gill et al, 2001

[70]

Ontario, Canada

Review of patients chart + a letter was sent to the treating doctor if inappropriate e.g. long acting BZ explaining why medication was inappropriate and suggestions for alternative therapy.

Quasi-Experimental

1 LTC facility, 450 Patients

37.9% of inappropriate medications were withdrawn or changed after the letter.

2 months after follow-up letters

Elliot et al, 2001 [37]

Australia

Audit and 1 h meeting = feedback to all staff on prescribing compared to other hospitals and review of literature + posters in wards

Quasi-Experimental

9 hospitals (6 aged care 3 medical wards)

No sig reduction in BZ use. Sig increase in appropriate prescribing at 8 week (22%) and 6 months (30%) post intervention.

4-8 weeks (all) and 6 months (for 3 hospitals only) post intervention

Audit and Feedback + Education Targeting LTC

Study Design and Size

Result

Follow up

Roberts et al, 2001 [34]

QLD + NSW, Australia

1 = 11 hrs of problem based education session for nurses + wall charts, bulletins, telephone, visits. Written drug review for 500 selected patients. Report on review placed in patient's records and available to the GPs.

2 = Control

RCT

52 nursing homes, 13 (intervention), 39 (control).

Sig difference in the reduction of BZs between intervention (decreased 597 items/year/1000 residents) and control (increased 278 items/year/1000 residents).

12 months (end of study)

Batty et al, 2001 [35]

England/

Wales

Audit then:

1 = lecture to staff on literature review on appropriate prescribing of BZs. Feedback on prescribing compared to another hospitals. 2 = Bulletin (2 sided A4) with same information as lecture.

3 = Control

RCT

Elderly inpatients at 17 hospitals (6 lecture, 4 bulletin, 7 control)

No sig change in any group but verbal group increased appropriate prescribing by 15%, bulletin decreased appropriate prescribing (9%) and control remained the same.

4-6 weeks post intervention

Eide and Schjott, 2001

[33]

Norway

1 = Audit of BZ use, feedback to staff (reports and a presentation). Academic education to all staff by pharmacist, consisting of 6 simple rules for the use of hypnotics (data collected in 1995 and 2000). 2 = Control (data collected in 2000 only)

CT

10 LTC Facilities, 5 (intervention) and 5 (control)

Sig dif in the % of patients use BZS in control (44%) compared to intervention (24%) post intervention. Sig higher dose of BZs in intervention group in 2000 (60%) compared to 1995 (38%).

5 years post intervention

Crotty et al, 2004 [71]

Adelaide,

Australia

Audit then:

1 = GP received education and guidelines and audit of use. Nurses received education in behaviour management and all staff received education on reducing psychotropic medication use

2 = control

MRP

20 LTC facilites, 10 (intervention) and 10 (control)

No sig reduction in BZ use (6.3%, intervention, 0% control), no significant decrease in long acting BZs (2.8% intervention and 0.9% control) and no sig difference in BZ being prescribed on a as needed basis (4% intervention and 1% control)

2nd audit was at 7 months (end of study)

  1. BZ = benzodiazepine, GP = General Practitioner, Av = Average, Sig = statistically significant (p < 0.05), LTC = long term care, OT's = Occupational Therapists, RCT = Randomized controlled trial, CT = Controlled trial, RT = randomized trial, MPR = Matched pair randomisation
