Blalock 2010.
| Methods | Randomised trial | |
| Participants | 186 elderly participants (intervention 93; control 93). 100 community pharmacies from the same chain, located in North Carolina USA Year of study: Not stated. |
|
| Interventions | Quote "Intervention was a face‐to‐face medication consultation conducted by a community pharmacy resident. The pharmacist reviewed the patient’s medications and identified potential problems in their drug therapy. Special attention was given to medications that have been found to increase the risk of falling, with an emphasis on Central Nervous System (CNS)‐active medications using structured algorithms. Control group received no medication consultation. Participants in both groups received a packet containing 2 brochures on the prevention of falls developed by the Centers for Disease Control and Prevention (What You Can Do to Prevent Falls and Check for Safety: A Home Fall Prevention Checklist for Older Adults)." 1 45‐minute meeting Duration 12 months |

| Outcomes | Number of falls | |

| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Low risk | Quote "Random assignments will be based on a list of random numbers generated using statistics software package" |
| Allocation concealment (selection bias) | Low risk | Quote "620 envelopes will be prepared such that each envelope includes a card on which either 'Experimental Group' or 'Control Group' is written. The envelopes will be sealed and arranged sequentially, by the list of random numbers." |
| Blinding of participants and personnel (performance bias) All Outcomes/Outcome 1 | Low risk | Protocol states that participants were blinded but pharmacists were not. |
| Blinding of outcome assessment (detection bias) All Outcomes/Outcome 1 | Low risk | Quote "To monitor data quality, all data collection instruments will be reviewed by a research assistant immediately upon their return by study participants. In cases where participants have missed items or provided incomplete, illegible, or ambiguous information, the research assistant will follow‐up with the participant by telephone to obtain the needed information. The research assistants will be blinded to participants' experimental group assignment." |
| Incomplete outcome data (attrition bias) All outcomes | Unclear risk | High attrition rate but reported as intention‐to‐treat analysis. Between group attrition < 10%. |
| Selective reporting (reporting bias) | Low risk | Main results reported |
| Other bias | Low risk | None |
