Study design and settings

This is a cross sectional study and has been carried out at an apex tertiary care hospital located in the capital city of India. The hospital includes several separate buildings housing different centres. This study was carried out in the “Main Hospital building” which is 8-floor building, in which most of the medical and surgical facilities for adults and children are located. Selected support services catering to main hospital have also been included in the study. This study was carried out during the period of Jan 2019 to March 2019.

Sample and sampling

Proportionate stratified random sampling method was chosen for selecting the study population. The total population in the selected areas of the hospital was around 2000 employees. Only those employees were considered for the study, which were willing to participate and were working for more than one year in the institute. Stratification was done based on the departments of various clinical and support departments, so at least 10% of minimum population is covered in the sample. Total calculated sample size for the study was 406.

Data collection

Interviews of employees were conducted in select representative work areas of hospitals. A structured interview questionnaire was designed after review of literature10. The reliability of interview questionnaire was scrutinized with pilot study and calculating coefficient alpha values. The values were ranging from 0.79 to 0.89.

Data procession and analysis

The Interview data was collected in Microsoft Excel^® software and was interpreted using IBM SPSS version 24.

Ethics statement

Approval for this study was obtained from the institutional ethics committee of All India Institute of Medical Sciences New Delhi.

This study was conducted in various clinical and non-clinical areas of the hospital Table 1

year. Out of which 5 are from clinical areas and 9 are from non-clinical areas. Pearson Chi-Square = 12.724, df=2, p=0.002 which shows there is strong relationship between workplace and incidence of STFs. Non-clinical areas show significantly higher incidence of STFs as compared to clinical areas. Hence, incidence was higher in support staff than Doctors and Nursing staff.

6 (0.5%) respondents from support service areas and 3 (0.1%) respondents from clinical areas had taken at least one day leave in the last one year due to incidence of slip, trip and fall at workplace.

AIIMS, New Delhi is an apex tertiary care hospital located in the capital of country. It is the largest public healthcare institution of the country. The institute has various centres of different specialities and super-specialities, but the main hospital building is the oldest structure and it consists of various departments. Main hospital building is an eight storey structure and it has total 1162 inpatient beds. Total 1,20,110 patients were admitted in the year 2019-20 in the main building of the hospital with an average length of stay of 9.9 days11. All these figures provide a glimpse of the workload on healthcare workers of hospital. There are many occupational hazards which are associated with hospitals, STFs is an underrated hazard. However, we observed in this study that the one-year incidence of STFs is about ten times than that of US healthcare.

Studies suggest that

Since there was no mechanism in the hospital to record the incidences of STFs among the heath care workers, the incidence of STFs was calculated using the interview of the sample population. Total 14 HCWs had at least one incident of STF in the last one year. Out of these, 9 were from the staff of non-clinical areas. Also, 13 out of these 14 have taken at least one day leave due to the incidence. When calculated, in totality 60 lost work days were observed. Majority of the STFs incidences recorded are from support areas of the hospital.
