  • a Higher scores indicate perception of safer practices.

  • b Higher scores indicate more severe/frequent access problems or more severe harm.

  • c Bivariate linear regression.

  • d Correlation coefficient.

  • e Deprivation measured using the Index of Multiple Deprivation; higher scores indicate higher deprivation levels.

  • f Safety climate measured using the instrument “PC-SafeQuest” (information available only from 31 practices).
