Haskard 2008.
| Methods |
Randomization procedure: Adequate. Physicians were randomized into one of four groups in a fully crossed 2 x 2 between‐subjects analysis of variance (ANOVA) design assigned by a computer generated random order Informed consent obtained: Yes Protection against contamination: Not Used Outcomes assessors blinded: Unclear. Two groups of raters rated 2000 audio tapes from all three time points and rating were z‐scored within rater to equate individual variability in use of the rating scale but blinding of raters was not mentioned Intention to treat analysis: Not stated as used Potential for unit of analysis error: Yes, acknowledged and adjusted. They randomized by physician and some measures are from patients who were different groups of patients at different times but this was corrected for with ANOVA design Comments on study quality: They used 156 physicians in order to provide adequate power with a robust and generalisable random‐effects model |

| Interventions |
Aim of study (hypothesis):
(Expected Outcome): The patient training will show positive effects on physician satisfaction and attitudes, although these effects will be weaker than those of physician training (because patients were not followed over time, and their training was relatively brief). Outcomes will be worse from training only one member of the dyad compared with training both or no training for physician and patient Content of intervention: Part I:First month. 6‐hr interactive workshop on core communication skills in healthcare teaching engaging, empathizing, educating patients about diagnosis, prognosis, and treatment and enlisting patients in mutually agreed upon treatment plans Second month: 6‐hr interactive workshop on patient adherence, enhancing patients’ health lifestyles, reducing health risk behaviours, and building confidence and conviction in patients to make health behavior changes Third month: 6‐hr interactive workshop on sources and nature of interpersonal difficulties between providers and patients, recognizing and assessing tension in relationships, acknowledging problems, discovering meaning, showing compassion, setting boundaries, and helping patients find additional support. Includes key provider‐patient communication competencies detailed in Kalamazoo Consensus statement Part II Coaching sessions (30‐45 min) Review of a routine audio‐taped patient visit, and additional tapes on communicating with terminally ill patients, informed consent, health beliefs, improving adherence, and working with patients with alcohol and nicotine dependence Review of an audio‐taped patient visit involving the issue of patient behavior change and received a copy of Motivational Interviewing (Miller & Rollnick, 1991) Review of a difficult interaction audio‐taped patient visit and receiving a copy of Conversation Repair (Platt, 1995) Patient training 20‐min waiting room pre‐visit intervention involved listening to audio CD with accompanying patient guide book focusing on planning and organizing concerns and questions for physician and encouragement to discuss treatment choices, negotiate best plan, repeat their understanding of the plan, follow‐up of care with their physician, asking questions about medications, tests, procedures, and referral Conceptual Focus: Shared decision making & motivational interviewing.
Number of providers receiving intervention: start group 1 = 31/156, group 1a = 35/156 end group 1 = 27/127, group 1a = 34/127. (Groups 1b & 2 did not receive the provider intervention but group 1b patients received the patient intervention) Number of patient receiving intervention: total number of patients = 2196 no data on patients per group Fidelity/integrity of intervention: Appointments with doctors and patients were audio‐taped |
|
| Outcomes | (They only reported significant results) Primary Outcomes: Patient satisfaction (when physician trained and not trained)Physician satisfaction with patient (when patient trained and not trained); as measured by patient and physician satisfaction surveys Consultation process: Physician information giving, satisfaction with consultation and sensitive communication, whether physician conducted a detailed physical examination. Satisfaction: Rating on Physician Information‐giving scale (Heisler), single item: whether recommend doctor to a friend Health behaviours: NA Health status: NA |
|
| Notes | Also collected Provider Outcomes: 1. Physician Satisfaction with patient. 2. Physician wanted aspects of the physician‐patient relationship to change. (questionnaires & audiotape ratings) | |
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Low risk | Used computer generated random order |
| Allocation concealment (selection bias) | Unclear risk | Article does not state that randomisation was concealed |
| Blinding (performance bias and detection bias) All outcomes | Unclear risk | Two groups of raters rated 2000 audio tapes from all three time points and ratings were z‐scored within rater to equate individual variability in use of the rating scale but blinding of raters was not mentioned. Physicians were aware of which patients would receive training |
| Incomplete outcome data (attrition bias) All outcomes | High risk | Had attrition rate of 29/156 (18.6%) of total randomized sample; control, physician only trained, and patient only trained had similar rates; but group with both physicians and patients trained had attrition rate of 29%. Did not use ITT analysis |
| Selective reporting (reporting bias) | High risk | Looked at numerous outcomes and reported only results that were statistically significant. "Bordeline significant items (P < 0.10) were available in an Appendix held by authors. Did not indicate that results had been adjusted for multiple comparisons |
| Other bias | High risk | Unclear whether protected against contamination, but not likely. Acknowledged and adjusted for unit of analysis error with design and in analysis. Collected baseline, but did not provide information on results or indicated that they adjusted for these differences |
