Pharmacy user: 70 patients with asthma
  • mean age: intervention 35.7 ± 10.2 years; control 38.7 ± 10.7 years

  • % female:intervention 52.8%; control 52.9%


Setting: rural
Country: Canada
Interventions Pharmacy worker‐directed intervention: pharmacist trained in an interactive, activity and case‐based program which focused on patient assessment, patient interviewing and communication skills
  • Delivered by: unclear

  • Type: self‐management; patient assessment, patient interviewing and communication skills

  • Mode of delivery: group

  • TDF: knowledge, skills

  • Duration: appears to have been a single afternoon with ongoing support visits and meetings as needed.


Pharmacy worker control: the same pharmacists delivered care to both intervention and control groups

Pharmacy user‐directed intervention: patients received education on asthma, assessment, and optimisation of drug therapy, with focus on a written asthma plan
  • Delivered by: pharmacist and referral to respiratory therapist and/or physician as needed

  • Type: self‐management; education; medication management; based on clinical practice guidelines

  • Mode of delivery: individual face‐to‐face

  • TDF: knowledge, behavioural regulation

  • Duration: an initial visit for information/education, referral to physician and pharmacist follow‐up: 2 weeks and at 1, 2, 4, and 6 months. Respiratory therapist follow‐up: 2 and 6 months

  • Follow‐up: 6 months (end of intervention)


Pharmacy user control: wait list with asthma education and advice as needed, as well as referral to respiratory therapist

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Randomization was accomplished through an Internet randomization service provided by the Epidemiology Coordinating and Research (EPICORE) Centre and the Centre for Community Pharmacy Research and Interdisciplinary Strategies (COMPRIS) at the University of Alberta. Randomization was stratified by centre."
Allocation concealment (selection bias) Low risk Centralised service, see above
Baseline outcome measures similar Low risk No differences for main outcomes
Baseline characteristics similar Low risk Differences for range characteristics ‐ text reported that this was controlled for in analyses.
Incomplete outcome data (attrition bias) 
 All outcomes Low risk Last value of ACQ carried forward where missing
Blinding of outcome assessment (detection bias) 
 All outcomes High risk It is possible that assessors were not blinded
Protection against contamination Low risk Cluster randomised
Selective reporting (reporting bias) Unclear risk Not noted
Other bias High risk Quote: “The sites did not apply the intervention uniformly. According to case report forms received, follow‐up was poor, few asthma management recommendations were made, and one‐quarter of patients in the intervention group never received a written action plan, [which was] the focus of the intervention. The follow‐up completed at each site varied, with some sites having less than 30% follow‐up at the time of the 6‐month visit. The low rate of follow‐up leads us to believe that the application of the intervention was also minimal at these sites.”
Blinding of participants and personnel (performance bias) 
 All outcomes High risk Caregivers/pharmacists involved in the study were not blinded.
