Contact rates within the nursing home: collected data and rates used in the model
| A- Contacts between staff members and residents | ||||
| Staff category | Mean no. of contacts/day/resident | Mean duration of contacts (min) | Risk level of contacts | Weighted no. of contacts/day |
| Nurse | 1 | 6.5 | 1 | 0.44 |
| Auxiliary nurse | 2 | 15 a | 1a | 2 |
| Receptionist | 1 | 1 | 0.5 | 0.04 |
| Activity leader | 1 | 20 | 0.5 | 0.67 |
| Ancillary staff (e.g. catering staff) | 2 | 40 | 0.5 | 2.67 |
| Therapist | 1 | 10 | 0.5 | 0.34 |
| Building maintenance staff | 1 | 5 | 0.5 | 0.17 |
| Total weighted number of contacts/resident/day | 6.33 | |||
| Computed Staff-Resident daily contact rate CSR | 6.33/63 = 0.1 | |||
| B- Contacts between staff members | ||||
| Average proportion of the working staff contacted over a given day, per staff member | Proportion of staff working on any given day in the NH | Risk level of contacts | Computed Staff-Staff daily contact rate CSS | |
| 90 % | 21 % | 0.25 | 0.045 | |
| C- Contacts between residents | ||||
| Mean no. of contacts/day/resident | Risk level | Weighted no. of contacts/day | Computed Resident-Resident daily contact rate CRR | |
| 5 | 0.5 | 2.5 | 2.5/100 = 0.025 | |
