The NHS South West London Integrated Care Board (ICB) is undertaking a comprehensive ten-year transformation plan to address growing healthcare demands across six boroughs—Croydon, Kingston, Merton, Richmond, Sutton, and Wandsworth—serving a population of 1.9 million. The initiative comes amid rising levels of ill health and financial pressures, with the ICB already operating within a significant budget deficit.
To assist with this challenge, the board engaged consultancy CF to analyze patient data from five hospital trusts, two mental health trusts, and four community providers. The consultancy employed its own analytics and modeling tools to track service usage patterns over the past year and predict changes over the next decade. Their analysis revealed that 8 percent of residents with high needs accounted for nearly 45 percent of NHS spending in the region. Without intervention, CF projects this group could grow to 14 percent of the population and consume 59 percent of spending by 2035-36.
Stella Vig, joint chief clinical transformation officer at the NHS South West London ICB, highlighted concerns over current spending patterns and the quality of patient experience. A key part of the transformation plan involves engaging clinical experts in discussions to interpret the data and identify potential improvements, rather than relying solely on clinicians to analyze raw figures.
One area identified for enhanced coordination is diabetes care, where many patients also manage additional health conditions. CF found that on average, these patients visit their general practitioners and attend outpatient appointments over once a month, receive about 50 prescriptions annually, visit accident and emergency departments twice a year, and experience four unplanned hospital admissions. The plan proposes consolidating appointments to reduce the burden on patients—for example, allowing individuals attending podiatry consultations to see a diabetes nurse during the same visit.
Efforts to reduce unnecessary hospital stays also feature prominently. Vig cited an example of patients unable to be discharged promptly because they must demonstrate they can manage stairs post-operation, but physiotherapy assessments are delayed, resulting in extended hospital stays. Additionally, some patients who live alone remain in hospital, despite feeling capable of managing at home with support from neighbors or remote assistance. The ICB acknowledges that existing guidelines sometimes contribute to these delays and is considering revising them to better align with patient needs.
The transformation plan projects that timely interventions could prevent serious health conditions in approximately 28,000 individuals. It also estimates a potential 17 percent reduction in the number of hospital beds required and a 36 percent decrease in outpatient appointments. Financially, the plan outlines a pathway to move from the current deficit toward a surplus by 2035-36.
By leveraging detailed data analysis and fostering collaboration between analytics experts and clinicians, the NHS South West London ICB aims to enhance patient care while managing resource constraints in a complex healthcare environment.
