*After intervention.
†First six scores are percentages, simply reflecting percentage of respondents who answered “yes” to single question or set of questions. The seven others are on scale of 1-5 and are based on mean of between three and six questions, each of which was scored between 1 and 5 for each respondent. For six of these seven scores, higher scores are better, though for “intention to leave” lower scores are better.
‡Indicates range of scores across intervention and control hospitals in first survey to give some context for level of change shown. Difference in change and corresponding confidence interval does not necessarily reflect difference in absolute change because of inclusion of covariates in models tested.
§These scores were not included in SPI1 evaluation.
