Change working patterns
Redesign shift structures to support changes such as removing 24-hour duties, introducing new day and night arrangements or changing on-call models.

Workforce — Roster Design Services
When working arrangements, staffing levels or service requirements change, the existing roster structure may no longer be the right one. MedModus helps healthcare organisations design and test alternative roster models — understanding what works, what doesn’t and the staffing required to make change possible.
Better roster management or optimisation can solve many scheduling problems. But sometimes the underlying roster structure needs to be reconsidered. We work with clinical and operational teams to redesign complex rosters around the realities of service delivery, staffing availability and workforce requirements — from changing an on-call model to bringing multiple clinical activities together within a more workable structure.
Redesign shift structures to support changes such as removing 24-hour duties, introducing new day and night arrangements or changing on-call models.
Understand the staffing required to provide appropriate clinical cover across days, nights, weekends and different service areas.
Bring together service coverage, working hours, rest, leave, skill requirements, fairness and individual constraints within a workable roster.
Design roster arrangements that recognise the interaction between on-call, inpatient, theatre, outpatient and other clinical responsibilities.
From roster design to a workable roster
Roster designs that appear workable on paper can become difficult when applied to real staff, services and constraints. MedModus combines healthcare workforce experience with roster modelling and optimisation capability, so proposed structures can be built and tested before they are adopted.
We model different shift arrangements and staffing levels, generate representative rosters and identify where competing requirements make a proposed design difficult or impossible to deliver.
Questions we help answer
Can the service eliminate 24-hour shifts?
How many staff would the alternative model require?
Can appropriate rest and working patterns be maintained?
Can on-call commitments be better aligned with elective activity?
What compromises are required when every constraint cannot be satisfied?

From service requirements to a practical roster design.
01 — UNDERSTAND
Review the existing roster, staffing profile, clinical requirements and the issues driving the need for change.
02 — DEFINE
Identify the clinical, contractual and staffing requirements the roster must accommodate — coverage, leave, rest, skills and working patterns.
03 — DESIGN
Design potential roster structures, shift patterns and staffing scenarios that address the agreed objectives.
04 — MODEL & TEST
Generate representative rosters to test feasibility and identify staffing gaps, conflicting requirements and trade-offs.
05 — REFINE
Review results with stakeholders and refine the design around what is achievable in practice.
A redesigned roster may solve a specific workforce or service challenge. In other cases, it establishes the structure and rules needed for ongoing roster optimisation or e-Rostering. Roster design capability is also an important part of many of our larger rostering engagements.

Anaesthesia
St. Vincent's University Hospital needed to understand the workforce impact of removing 24-hour shifts for anaesthesia NCHDs while maintaining theatre and ICU cover.

General Paediatrics
Three hospital services will combine in the new children's hospital. MedModus designed a greenfield General Paediatrics roster covering inpatient, on-call and outpatient commitments.

Surgical SHOs
On-call allocations were clashing with General Surgery theatre lists and outpatient clinics. MedModus redesigned the call roster to favour lower-impact days.
