Diversity of interpretations of the concept "patient-centered care for breast cancer patients"; a scoping review of current literature

RATIONALE, AIMS AND OBJECTIVES

Patient-centered care is considered a vital component of good quality care for breast cancer patients. Nevertheless, the implementation of this valuable concept in clinical practice appears to be difficult. The goal of this study is to bridge the gap between theoretical elaboration of "patient-centered care" and clinical practice. To that purpose, a scoping analysis was performed of the application of the term "patient-centered care in breast cancer treatment" in present-day literature.

METHOD

For data-extraction, a literature search was performed extracting references that were published in 2018 and included the terms "patient-centered care" and "breast cancer". The articles were systematically traced for answers to the following three questions: "What is patient-centered care?", "Why perform patient-centered care?", and "How to realize patient-centered care?". For the content analysis, these answers were coded and assembled into meaningful clusters until separate themes arose which concur with various interpretations of the term "patient-centered care".

RESULTS

A total of 60 publications were retained for analysis. Traced answers to the three questions "what", "why", and "how" varied considerably in recent literature concerning breast cancer treatment. Despite the inconsistent use of the term "patient-centered care," we did not find any critical consideration about the nature of the concept, regardless of the applied interpretation. Interventions that are supposed to contribute to the heterogeneous concept of patient-centered care as such, seem to be judged desirable, virtually without empirical justification.

CONCLUSIONS

We propose, contrary to previous efforts to define "patient-centered care" more accurately, to embrace the heterogeneity of the concept and apply "patient-centered care" as an umbrella-term for all healthcare that intends to contribute to the acknowledgement of the person in the patient. For the justification of measures to realize patient-centered care for breast cancer patients, instead of a mere contribution to the abstract concept, we insist on the demonstration of desirable real-world effects.

The economic impact of disease progression and death in hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer patients: using Korean nationwide health insurance claims data

OBJECTIVES

Recognizing the value of anticancer treatments based on progression-free survival and overall survival may help decision making in healthcare policy. We aimed to measure and compare the impact of disease progression and terminal state prior to death on healthcare costs in HR+, HER2- ABC patients.

METHODS

We conducted a retrospective study using Korean nationwide health insurance claims database between 1 September 2012 and 31 August 2017. The impact of disease progression was estimated by measuring the average incremental monthly cost per patient during 1 year after progression compared to 1 year before progression. Death-related costs per patient per month (PPPM) were measured for those who died within 1 year after progression. Generalized estimating equation (GEE) was used to estimate the variations in PPPM costs by progression and death with adjustment for clinical factors.

RESULTS

After progression, 1,636 patients expensed $2,892 per month more on average than before progression ($3762 vs. $870). The GEE analysis with adjustment for baseline characteristics showed that PPPM costs increased by 3.46 folds (95% CI = 3.06-3.93) after progression. Also, PPPM costs were 1.74 (95%CI = 1.43-2.12) times higher in patients who died within 1 year after progression relative to survived patients. When considering the interaction between progression and death, deceased patients showed higher increased ratio of PPPM costs after progression (4.91; p=value<.0001) than survived patients (2.95; 95% CI = 2.61-3.34).

CONCLUSIONS

From the payer's perspective, more healthcare costs incurred during the progression state than terminal state in HR+, HER2- ABC patients. The impact of disease progression emphasizes the importance of effectively treating HR+, HER2- ABC patients.
