Questionnaire design
The questionnaire consisted of questions on demographics, occupation, lifestyle, the ICP workload, utilization of PPE, OHH, and PHP needs of interventional cardiologists. OHHs were assessed with respect to orthopedic pain and comorbidities. A detailed assessment of pain location, pain severity, pain management, and pain-related sick leave was conducted. The verbal pain rating scale15 was used to assess pain severity. This questionnaire also included questions of satisfaction with the current PPE used in ICPs, limitations associated with PPE, concerns of career development and PHP needs. Non-interventional cardiologists were guided only to questions on demographics, occupation, lifestyle and OHH.
