Khan 2011‐ Hispanic.

Methods Parallel randomised controlled clinical trial (RCT)
Randomisation ratio: 67 intervention:62 control
Superiority design
Participants Inclusion criteria:
  • Age over 18 years

  • Verbal fluency in English

  • Responsible for own diabetes self‐management


Exclusion criteria: not stated
Diagnostic criteria: not stated
Interventions Number of study centres: 1
Treatment before study: does not say
Intervention: was the 'Living Well with Diabetes Multimedia Program.' Aim of the intervention was to improve participants' diabetes self‐management behaviours, therapy intensification and glycaemic control over a 3‐month period
19 bilingual computer multimedia lessons on diabetes self‐management: Content included an introduction to diabetes, blood glucose management, oral medications and insulin, nutrition and physical activity, depression and stress, oral hygiene and the prevention of complications (eye, foot, cardiovascular, kidney diseases). Each lesson targeted a specific self‐care objective. The programme also consisted of more than 160 testimonials from African American and Hispanic patients with diabetes related to diabetes self‐care, emphasising barriers to care and challenges and personalised solutions that they or family members had encountered. Different testimonials and messages were used to relate both language and culturally appropriate information to African American or Latino users
Programme available to participants in waiting areas before attending general education. Each lesson targeted a specific objective according to Gagne's theory of learning and the component display theory
Control: given an American Diabetes Association brochure on self‐management ("Living with Diabetes," written at 6th grade level)
Co‐interventions: All participants received traditional diabetes self‐management education. This involved group educational sessions, individualised risk assessment and goal setting
Outcomes Outcomes reported in abstract of publication: diabetes knowledge, self‐efficacy, behaviours, medications prescribed, HbA1c and BP levels over 3 months
Study details Run‐in period: none stated
Study terminated before regular end: no
Publication details Language of publication: English
Funding: Agency for Healthcare Research and Quality
Publication status: peer‐reviewed journal

Notes
Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Comment: random allocation by research assistant pulling a card out of a box, with each card indicating group assignment
Allocation concealment (selection bias) Unclear risk Comment: not mentioned
Blinding of participants and personnel (performance bias) 
 Objective outcomes High risk Comment: participants not blinded because of the nature of the study; physicians were blinded

 Subjective outcomes High risk Comment: participants not blinded because of the nature of the study; physicians were blinded
Blinding of outcome assessment (detection bias) 
 Lab tests: Lipids, HBA1C Unclear risk Comment: does not say whether or not research assistants were blinded; physicians were blinded
Blinding of outcome assessment (detection bias) 
 Subjective outcomes High risk Comment: participants not blinded completing questionnaires
Incomplete outcome data (attrition bias) 
 Objective outcomes Low risk Comment: 12/129 lost to follow‐up, roughly equal in control/intervention group. Reasons for dropping out included relocation, phone disconnection and leaving the county health system
