A retrospective analysis of above-mentioned data, covering the period January-April 2019 and January-April 2020, was carried out. The evaluation of the staff's absence included all workers employed under an employment contract: 713 workers in 2019 and 747 workers in 2020. The variable number of employees was a result of the employment dynamics in the subsequent 2 years, due to variable quantity of healthcare services that were contracted with the national payer and changes in the form of employment of some hospital workers.Three types of analyses were carried out: global analysis, analysis taking into account division into specific professions and the analysis of absence in different hospital organizational units/areas. The absences due to medical reasons, holidays or childcare were analyzed together. The analysis of performing the contracted tasks was shown in relative values ( %). The analysis included the structure of contracted services dividing them into: Orthopedics (alloplasty and others), rehabilitation (person-day), rheumatology (drug trials and others). Considering the rehabilitation unit, it was subdivided into inpatient and outpatient wards due to temporary closure of the outpatient ward.
Work attendance of more than 700 hospital workers was evaluated. The assessment of the number of medical services that were performed was based on monthly reports prepared for the national payer of health services.
