Placental growth factor testing for suspected pre-eclampsia: a cost-effectiveness analysis.

OBJECTIVE: To calculate the cost-effectiveness of implementing PlGF testing alongside a clinical management algorithm in maternity services in the UK, compared with current standard care. DESIGN: Cost-effectiveness analysis. SETTING: Eleven maternity units participating in the PARROT stepped-wedge cluster-randomised controlled trial. POPULATION: Women presenting with suspected pre-eclampsia between 20+0 and 36+6  weeks' gestation. METHODS: Monte Carlo simulation utilising resource use data and maternal adverse outcomes. MAIN OUTCOME MEASURES: Cost per maternal adverse outcome prevented. RESULTS: Clinical care with PlGF testing costs less than current standard practice and resulted in fewer maternal adverse outcomes. There is a total cost-saving of UK£149 per patient tested, when including the cost of the test. This represents a potential cost-saving of UK£2,891,196 each year across the NHS in England. CONCLUSIONS: Clinical care with PlGF testing is associated with the potential for cost-savings per participant tested when compared with current practice via a reduction in outpatient attendances, and improves maternal outcomes. This economic analysis supports a role for implementation of PlGF testing in antenatal services for the assessment of women with suspected pre-eclampsia. TWEETABLE ABSTRACT: Placental growth factor testing for suspected pre-eclampsia is cost-saving and improves maternal outcomes.

The administration of intermittent parathyroid hormone affects functional recovery from trochanteric fractured neck of femur: a randomised prospective mixed method pilot study.

AIMS: We wished to assess the feasibility of a future randomised controlled trial of parathyroid hormone (PTH) supplements to aid healing of trochanteric fractures of the hip, by an open label prospective feasibility and pilot study with a nested qualitative sub study. This aimed to inform the design of a future powered study comparing the functional recovery after trochanteric hip fracture in patients undergoing standard care, versus those who undergo administration of subcutaneous injection of PTH for six weeks. PATIENTS AND METHODS: We undertook a pilot study comparing the functional recovery after trochanteric hip fracture in patients 60 years or older, admitted with a trochanteric hip fracture, and potentially eligible to be randomised to either standard care or the administration of subcutaneous PTH for six weeks. Our desired outcomes were functional testing and measures to assess the feasibility and acceptability of the study. RESULTS: A total of 724 patients were screened, of whom 143 (20%) were eligible for recruitment. Of these, 123 were approached and 29 (4%) elected to take part. However, seven patients did not complete the study. Compliance with the injections was 11 out of 15 (73%) showing the intervention to be acceptable and feasible in this patient population. TAKE HOME MESSAGE: Only 4% of patients who met the inclusion criteria were both eligible and willing to consent to a study involving injections of PTH, so delivering this study on a large scale would carry challenges in recruitment and retention. Methodological and sample size planning would have to take this into account. PTH administration to patients to enhance fracture healing should still be considered experimental.
