Emergency contracting and the delivery of elective care services across the English National Health Service and independent sector during COVID-19: a descriptive analysis

Patient outcomes, efficiency, and adverse events for elective hip and knee replacement in private and NHS hospitals: a population-based cohort study in England

Background

Since the early 2000s, the National Health Service (NHS) in England has expanded provision of publicly funded care in private hospitals as a strategy to meet growing demand for elective care. This study aims to compare patient outcomes, efficiency and adverse events in private and NHS hospitals when providing elective hip and knee replacement.

Methods

We conducted a population-based cohort study including patients ≥18 years, undergoing a publicly funded elective hip or knee replacement in private and NHS hospitals in England between January 1st 2016 and March 31st 2019. Comparative probability was estimated for three patient outcome measures (in-hospital mortality, emergency readmissions with 28 days, hospital transfers), two efficiency measures (pre-operative length of stay (LOS) >0 day and post-operative LOS >2 days), and four adverse events (hospital-associated infection, adverse drug reactions, pressure ulcers, venous thromboembolism). Probit regression was used to adjust for observable confounding followed by instrumental variable (IV) analyses to also account for unobserved confounding at the patient-level. Propensity score matching was then used as a robustness check.

Findings

Our study sample included 169,232 patients in private hospitals, and 262,659 patients in NHS hospitals. Estimates from probit regression indicated that treatment in private hospital was associated with reduced probability of in-hospital mortality (-0.0009, 95% CI -0.0010, -0.0007), emergency readmissions (-0.0181, 95% CI -0.0191, -0.0172), hospital transfers (-0.0076, 95% CI -0.0084, -0.0068), prolonged post-operative LOS (-0.1174, 95% CI -0.1547, -0.0801), hospital-associated infection (-0.0115, 95% CI -0.0123, -0.0107), adverse drug reactions (-0.0051, 95% CI -0.0056, -0.0046), pressure ulcers (-0.0017, 95% CI -0.0019, -0.0014), and venous thromboembolism (-0.0027, 95% CI -0.0031, -0.0022). IV analyses produced no significant differences between private and NHS hospitals, except for lower probability in private hospitals of hospital-associated infection (-0.0057, 95% CI -0.0081, -0.0032), and greater probability in private hospitals of prolonged post-operative LOS (0.2653, 95% CI 0.1833, 0.3472). Propensity score matching produced similar results to probit regression.

Interpretation

Our findings indicate there is potentially important unobservable confounding at the patient-level between private and NHS hospitals not adjusted for when using probit regression or propensity score matching.

The COVID-19 Pandemic and the Private Health Sector: Profiting without Socially Contributing

The COVID-19 pandemic necessitated the mobilization of all available health care resources, including private, for-profit ones. The aim of this multiple methods study (combination of document and secondary data analysis) was to assess government regulations facilitating the private health sector's participation in the COVID-19 response in Greece. During the pandemic, the government made three successive increases in private providers' reimbursement fees, provided additional financial incentives to private providers, and allocated €280 million of emergency funding for the private sector's involvement in the national COVID-19 response. In response, private hospitals made available on average 2.2% of their total bed capacity per epidemic wave for the treatment of COVID-19 patients and 1.7% of their total bed capacity for the treatment of non-COVID-19 patients transferred from National Health System (NHS) hospitals. In 2020 the five largest health care corporate groups maintained their revenues, while in 2021 they increased them by 18.7%-a striking comparison with the 9% recession experienced by the Greek economy in 2020 and its 8.4% recovery in 2021. In a time of an acute public health crisis, private health care providers responded to society's pressing health care needs by insulating their facilities from COVID-19 patients and NHS patient transfers, minimizing their social contribution and safeguarding their revenues and profits.
