Table 2 Factors related to rates of patients’ perception of communication from GPs to medical specialists about their illness when they are referred (multi-response logistic multilevel analysis)

From: Patients’ perception of communication at the interface between primary and secondary care: a cross-sectional survey in 34 countries

Ncountries = 34
NGPs = 6519
Npatients = 38,432
Odds Ratioa(CI)
Patient level
 The patient has a personal doctor1.99(1.67, 2.36)
GP level
 Frequency of referral letters sent to medical specialists by GPs (ref. more than ‘seldom or never’)
 Seldom or never0.75(0.64, 0.87)
 Score of job satisfaction of GPs1.1(1.00, 1.22)
Country level
 List system in place0.76(0.41, 1.41)
 Variance country level1.79 
 Variance GP level1.88 
 Percentage of reduction of variance (Country level)b4.2% 
 Percentage of reduction of variance (GP level)c0.7% 
 Intraclass correlation (ICC) country level26% 
 Intraclass correlation (ICC) GP level27% 
  1. CI 95% confidence interval
  2. aadjusted also for age and gender of GPs, practice location, employment status of GPs, age and gender of patients, income of patients, perceived health status of patients and presence of at least one longstanding disease
  3. bthis percentage was calculated by using the variance at a country level of the initial model (variance initial model =1.88)
  4. cthis percentage was calculated by using the variance at a GP level of the initial model (variance initial model =1.90)
