Additional file 4: Table S4. of Reasons for encounter by different levels of urgency in out-of-hours emergency primary health care in Norway: a cross sectional study

Reasons for encounter, ICPC-2 chapters, red urgency level (life threatening). Counts, proportions. Total, minimum and maximum incidence in individual OOH casualty clinics. (PDF 79 kb

Distance and consultation rates, nonlinear regression.

<p>Relative change (%) in consultation rates when moving 50 kilometres away from the casualty clinic for different distance measures. Constants and coefficients (with 95% confidence interval (CI)) for exponential functions.</p

Postcode based travel time and consultation rate at the casualty clinic.

<p>Relationship between average postcode based travel time (minutes) from Watchtower municipalities to casualty clinic and consultation rate at the casualty clinic (per 1 000 inhabitants per year). Each point represents rate in one municipality for one year (2007–2011). Circles indicate monomunicipal and crosses intermunicipal out-of-hours districts.</p

Quality of postcode based coordinates by a five point quality scale.

<p>Quality of postcode based coordinates by a five point quality scale.</p

Correlation analysis of different travel time measures at short distances by correlation coefficients for the relationship between different travel time measures and mean travel time as calculated by Statistics Norway to casualty clinic.

<p>Analyses on municipalities with shorter distances than indicated on the X-axis (N = 3 to 11). Critical r curves corresponding to p = 0.05. r-values between these curves are statistically non-significant.</p

Postcode based distance and consultation rate at the casualty clinic.

<p>Relationship between average postcode based distance (kilometres) from Watchtower municipalities to casualty clinic and consultation rate at the casualty clinic (per 1 000 inhabitants per year). Each point represents rate in one municipality for one year (2007–2011). Circles indicate monomunicipal and crosses intermunicipal out-of-hours districts.</p

Mean absolute error (MAE) of distance measures in intermunicipal and monomunicipal out-of-hours districts.

<p>Deviations (absolute) from mean distance to casualty clinic (kilometres) as calculated by Statistics Norway for the different measures. Error bars indicate 95% confidence intervals.</p

Comparison of different travel time category measures to casualty clinic.

<p>Correlation analysis of relationship between mean travel time for inhabitants and other travel time measures to casualty clinic. The analyses are performed for different maximum travel times. r = correlation coefficient.</p

Baseline data, Watchtower municipalities, sequence by mean distance to casualty clinic.

Correlation analysis of different distance measures at short distances by correlation coefficient, r, for the relationship between different average distance measures and mean travel time to casualty clinic.

<p>Analyses on municipalities with shorter travel times than indicated on the X-axis (N = 3 to 11). Critical r curves corresponding to p = 0.05. r-values between these curves are statistically non-significant.</p
