Methods | Design: RT Groups: intervention (asthma management); control group (usual care) |
|
Participants | Pharmacies: 5 Pharmacy workers: not reported ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ Pharmacy user: 70 patients with asthma
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
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
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. |
