Competing Interests

I have read the journal’s policy and the authors of this manuscript have the following competing interests: Authors were conducting quantitative analysis for Polish Association of Employers of Poviat Hospitals (OZPSP – Ogólnopolski Związek Pracodawców Szpitali Powiatowych) who provided data for the study. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
