Scoring frontline provider surveys
| Survey instrument | Scoring |
| Work Relationship Scale (WRS) | Due to survey burden and partial overlap with other scales (see below), the original 15-item WRS was reduced to 9 items based on the original Rasch item analyses and areas of overlap with items on the other scales. Items 1, 2, 4, 5, 8, 9, 11, 14 and 15 of the original items were retained and references to clinic were changed to team.51 A new Rasch item analysis and principal components analysis will be conducted to assure that unidimensionality has been retained. Total scores will be calculated per respondent (possible range 9–45), averaged across respondents for each facility and facilities will be compared using SAS PROC Mixed. |
| Relational Coordination (RC) Survey | RC scores are first calculated for each individual by summing the scores of all roles (eg, care transitions staff, inpatient attending, outpatient primary care nurse, etc) for each dimension (eg, frequent communication) and then dividing by the number of responses. The overall RC score for each participant is derived by calculating the mean of the seven individual scores (range 1–5).53 RC scores at the facility level are calculated for each functional group (eg, care transitions manager, hospitalist, primary care nurse or physician) by calculating the mean of each dimension for all members of the functional group, and then a facility RC mean. The primary analyses will use the facility mean score, and secondary analyses will examine variation in RC scores among functional groups (care transitions staff, inpatient attendings, primary care teams). |
| Adapted Safety Organization Scale | Originally described by Vogus and Sutcliffe54 as a measure of self-reported behaviours enabling a safety culture in-hospital nursing units. Original respondents were nurses only. Questions 1, 3 and 4 were used unmodified. Questions 2, 4, 7, 8 and 9 were modified to be focused on care transitions and preventing readmissions. For example, the original question 2 was ‘we talk about mistakes and ways to learn from them’. The modified version is ‘we talk about readmissions and ways to learn from them’. The original question 5 was dropped as it dealt only with inpatient nursing shift report giving. The responses were kept the same. As for the Work Relationship Scale above, a Rasch item analysis and principal components analysis will be conducted to assure that unidimensionality has been retained. Total scores will be calculated per respondent (possible range 8–56), averaged across respondents for each facility and facilities will be compared using SAS PROC Mixed. |
