Dual-theatre high-intensity lists (HIT) for day-case minimally invasive parathyroidectomy: a prospective service evaluation.
Article in BMJ open quality, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundElective ENT waiting lists and constrained theatre capacity require pathway redesign that increases surgical throughput without compromising safety. At our trust, patients awaiting minimally invasive parathyroidectomy faced waits of approximately 52 weeks, while routine intraoperative frozen-section confirmation created predictable theatre downtime. LOCAL PROBLEM: Minimally invasive parathyroidectomy is well suited to day-case high-intensity theatre delivery because selected patients follow a standardised pathway. However, evidence for dual-theatre models in this setting is limited.
methodsWe conducted a prospective registered service evaluation of two dual-theatre, 5 hour morning high-intensity theatre sessions for day-case minimally invasive parathyroidectomy at a UK NHS trust. Predefined timings, throughput and safety/balancing outcomes were collected prospectively from routine theatre documentation.
interventionTwo adjacent theatres were allocated by operative side with staggered starts. One consultant surgeon alternated between rooms while assistants completed haemostatic checks and wound closure under supervision. Six selected day-case patients were scheduled per session; eligibility required concordant imaging and suitability for day-case surgery.
resultsTwelve patients underwent successful minimally invasive parathyroidectomy across two morning sessions. Six cases were completed within each 5 hour session, and all procedures were completed by 13:00 on both days. Mean knife-to-specimen time was 18.4 min, mean frozen-section duration was 24.1 min, mean incision-to-closure time was 42.9 min, and mean call-to-incision time was 42.2 min. All patients had histological confirmation of parathyroid adenoma and postoperative biochemical improvement.
conclusionsA dual-theatre high-intensity theatre model can convert frozen-section waiting time into productive operating time and substantially increase throughput for carefully selected day-case parathyroidectomy pathways. Wider implementation requires careful patient selection, operational planning, pathology availability, staff engagement and prospective monitoring of safety, cost and workforce impact.
