Using health status to measure NHS performance: casting light in dark places

Choice in the presence of experts: The role of general practitioners in patients' hospital choice

This paper considers the micro-econometric analysis of patients' hospital choice for elective medical procedures when their choice set is pre-selected by a general practitioner (GP). GPs have a dual role with regard to elective referrals in the English NHS, advising patients and at the same time taking account of the financial implications of referral decisions on local health budgets. The paper proposes a two-stage choice model that encompasses both patient and GP level optimization. It demonstrates that estimators that do not take account of strategic pre-selection of choice sets may be biased and inconsistent. We find that GPs as patients' agents select choice options based on quality, but as agents of health authorities also consider financial implications of referrals. When considering these choice options, patients focus on tangible hospital attributes, like amenities.

Variation in Patient-reported Outcomes Across Hospitals Following Surgery

BACKGROUND

Although there is growing interest in applying patient-reported outcomes (PROs) toward surgical quality, the extent to which PROs vary across hospitals following surgical procedures is unknown.

OBJECTIVES

We examined variation in PROs, specifically health-related quality of life (HRQOL), across hospitals performing bariatric surgery.

RESEARCH DESIGN

A retrospective cohort study.

SUBJECTS

The Michigan Bariatric Surgery Collaborative is a statewide consortium of 39 hospitals performing laparoscopic gastric bypass, gastric banding, or sleeve gastrectomy (n=11,420 patients between 2008 and 2012).

MEASURES

We examined generic and disease-specific HRQOL measured by the Health and Activities Limitations Index (HALex) and Bariatric Quality of Life index (BQL) preoperatively and at 1 year. We measured the variation in postoperative HRQOL across hospitals, and the effect of risk and reliability adjustment on hospital ranking.

RESULTS

In this cohort, HRQOL varied by 56% (HALex) and 37% (BQL) across hospitals. Patient factors accounted for 58% (HALex) to 71% (BQL) of the variation in HRQOL across hospitals. After risk and reliability adjustment, HRQOL varied by 18% (by HALex) and 14.5% (by BQL) across hospitals, and the proportion of patients who experienced a large improvement in HRQOL by HALex ranged from 33% to 69% and 67% to 92% by BQL. After adjusting for patient factors and reliability, these differences diminished to 55%-64% (HALex) and 79%-84% (BQL).

CONCLUSIONS

Patient factors explain a large proportion of hospital-level variation in PROs following bariatric surgery, underscoring the importance of risk adjustment. However, some variation in PROs across hospitals remains unexplained, suggesting PROs may represent a viable indicator of hospital performance.

Health services research: evolution and applications

Health services research (HSR) is broadly focused on characterizing and improving the access, quality, delivery, and cost of health care. HSR is a multidisciplinary field, engaging experts in clinical medicine and surgery, policy, economics, implementation science, statistics, psychology, and education to improve the care of patients across all specialties. This article summarizes the evolution and distinctive attributes of HSR and present several real-world applications.
