ZS provides an analytically driven understanding of patient behaviour to help your organisation become more patient-centric and reduce disparities in care:

Enterprise readiness: Is your organisation prepared for patient centricity? We’ll assess your readiness and search for the overlaps between patient needs and business objectives to find the best opportunities for delivering next-level patient initiatives. We then work with your team to build out the capabilities and processes to help you succeed in delivering exceptional experiences and value to patients and your business.

Health equity: We take a multifaceted approach to tackling health equity, leveraging our research capabilities, healthcare expertise, and problem-solving approaches to uncover fresh insights and incubate innovation at the leading edge of the fight against health inequities. We drive change by embedding health equity across our work, from strategy and insights to execution and operations. We support our clients in maximising their own impact and driving meaningful change progress in the populations they serve while also partnering directly with organisations across healthcare, such as the Healthcare Leadership Council, to understand and drive meaningful and measurable progress.

Insights and research: Precise insights into patient decision-making and behaviours provide the baseline for improving patient engagement. We offer a broad range of collaborative market research, data analysis, behavioural and health decision science research, social listening, patient barrier analysis, and more.

Patient strategy: The right message at the right time to the right audience is the key to successful communications. We assess your value proposition, map the patient journey, segment your market, and craft your messaging to help you interact with patients in a meaningful way.

Patient support and programme measurement: We can help you plan your investments, promotions, and channel mix, and measure the impact through tracking studies, closed-loop measurement approach to DTC impact measurement, marketing mix models, KPI tracking and benchmarking, and predictive modelling.
