IT Interventions in Primary Healthcare
Improvement in patient outcomes through enhancing collaborative practice and safety
A systematic review of RCTs

Inclusion Criteria
1. Intervention based on IT
2. Intervention performed in primary care
3. Outcomes were on reported medication safety
4. Only RCTs

A Policy-maker's perspective
Clinical decision Support
CDS seemed to be successful when tailored to specific medication cases or subsets.
Study design
Systematic review
Data extraction
Third party reviewer
Clear methods
Diverse group of patients studied

Group 3: Information technology interventions
to improve medication safety in primary
care: a systematic review

Directions for Future Study
As a policymaker, there is not enough conclusive evidence in this paper to support the widespread implementation of any one of these IT primary care intervention systems.
Collaboration between pharmacists and physicians seemed to have a positive effect on reducing the incidence of medical errors. This was supported by a reference to a RCT of a system called the pharmacist-led information technology intervention for medication errors (PINCER).
However, this RCT was not evaluated in the systematic review (it was published outside of the search date range).
PINCER protocol: Collaboration between pharmacist and physicians to best identify and counter medication errors, coupled with improved education and patient counseling. (Avery et al, 2009)
The PINCER trial was successful in reducing medication errors and in the monitoring of errors associated with NSAIDs, beta-blockers, and ACE inhibitors. (Avery et al, 2012)
Promising IT primary care intervention systems such as CDS and pharmacist-led IT interventions should be further researched and optimized prior to wide-spread implementation.
Standardized high quality RCTs examining the effect of IT interventions on medication safety in primary care settings are needed.
Computerized Provider Order Entry (CPOE) is an integrated IT framework that houses patient data and acts a means for the clinical team to operate best.
Such systems also include Clinical Decision Support.
Universally agreed as ideal environment, but costly and prone to being outdated, misused and underused.
Inclusion and exclusion criteria
Excluded everything except RCT
Inclusion criteria had many definitions
Included studies
Only ten RCT met inclusion criteria, and of that only three showed reductions in unsafe prescribing
Only three studies included follow up information
Study durations ranged from 3-30 months
Inadequate blinding and concealment of allocation in majority of studies
Lack of generalization
Research Question
P: Patients receiving medication in any primary care setting
I: any IT intervention
O: improvement of medication safety
Thank you for your attention,
we would be happy to entertain
your questions
3 of 6 studies evaluated effectively reduced unsafe prescribing

Consider alert fatigue with CDS

Pharmacists led IT intervention
Of the two studies evaluated, both decreased prescribing of potentially inappropriate medication in elderly or unsafe prescribing in pregnancy
Web Based and Telemedicine
Neither showed reduction in ADEs

Neither had medication safety as a primary outcome however, ADEs were important secondary outcomes
What else?
A 2007 retrospective file review of 1801 drug prescription in out-patient in medical walk-in clinic

The drug interaction database correctly identified 81% of clinically relevant adverse drug interactions, but also flagged up several clinically non significant interactions

A 2010 quasiexperimental, pretest-post-test study examined the impact of CPOE in primary care.

5,016 prescriptions written by hand before using the system were compared with 5,153 electronically prescribed documents.

10% reduction in prescribing error (18% to 8%) such as illegibility errors, use of inappropriate abbreviations, and missing information
A 2014 systematic review of 16 studies that met the inclusion criteria concluded that hospital use of CPOE showed more than 50% reduction in preventable ADEs.

A 2014 study on cost-effectiveness of CPOE in improving medication safety showed that it was in fact cost-effective and also decreased medication errors and ADEs.
