Disentangling the value equation: a step forward in value-based healthcare

TL;DR

This paper proposes a method to calculate a single value for patient-centered outcomes in value-based healthcare using breast cancer patient data.

Contribution

It is the first to combine ICHOM's patient-centered outcomes into a single numerator figure for value-based healthcare.

Findings

Pain had the highest weight among patient-reported outcomes in the composite indicator.

The composite indicator of patient-centered outcomes was more informative than health-related quality of life measures.

The calculated weights were robust to sensitivity analysis.

Abstract

The value equation of value-based healthcare (VBHC) as a single figure remains ambiguous, closer to a theoretical framework than a useful tool for decision making. The challenge lies in the way patient-centred outcomes (PCOs) might be combined to produce a single value of the numerator. This paper aims to estimate the weights of PCOs to provide a single figure in the numerator, which ultimately will allow a VBHC figure to be reached.

A cohort of patients diagnosed with breast cancer (n = 690) with a 6-month follow-up recruited in 2019–20 across six European hospitals was used. Patient-reported outcomes (PROs), clinical-related outcomes (CROs), and clinical and socio-demographic variables were collected. The numerator was defined as a composite indicator of the PCOs (CI-PCO), and regression analysis was applied to estimate their weights and consequently arrive at a single figure.

Pain showed as the highest weight followed by physical functioning, emotional functioning, and ability to work, and then by a symptom, either arm or breast. PCOs weights were robust to sensitivity analysis. The CI-PCO value was found to be more informative than the health-related quality of life (HRQoL) value.

To the best of our knowledge, this is the first research to combine the PCOs proposed by ICHOM to provide a single figure in the numerator of the value equation. This figure shows a step forward in VBHC to reach a holistic benchmarking across healthcare centres and a value-based payment. This research might also be applied in other medical conditions as a methodological pathway.
