Background Organisational values are widely assumed to have positive effects on performance and staff. National Health Service (NHS) trusts in England have accordingly chosen their own organisational values. However, there has been no survey of the values adopted, and there is little evidence that the choice of values per se has consequences for outcomes. We comprehensively described trusts’ organisational values, using natural language processing to identify common themes. We tested whether the choice of themes was associated with outcomes for patients and staff.
Methods We collected data on trusts’ values (from their websites), performance (Summary Hospital-level Mortality Indicator (SHMI) statistics, Care Quality Commission (CQC) ratings), sickness absence rates (SAR) and staff opinions (NHS Staff Survey responses). We first characterised values based on lexical properties then progressed to semantic analysis, using Google’s Universal Sentence Encoder, to transform values to high-dimensional embeddings, and k-means clustering of embeddings to semantically cluster values into 12 common themes. We tested for associations between trusts’ use of these themes and outcomes.
Results Organisational values were obtained for 221 of 228 NHS trusts, with 985 values in total (480 unique). Semantic clustering identified themes including ‘care’, ‘value respect’ and ‘togetherness’. There was no significant association between themes and SHMI or CQC ratings. However, themes predicted trusts’ SAR (p=0.001, R2=0.159), with use of ‘care’, ‘value respect’, ‘aspirational’ and ‘people’ all significant predictors of increased sickness absence; themes also predicted staff opinions on ‘Equality, diversity and inclusion’ (p=0.011, R2=0.116), but with ‘supportive’ and ‘openness’ predicting more negative responses.
Conclusion A trust’s adoption of individualised organisational values does not seem to make a positive difference to its patients or staff. These findings should give NHS managers pause for thought, challenging them to reconsider their reliance on value-defining initiatives, and to seek evidence that a focus on values has measurable benefits on outcomes.
