Incidence and predictors of immediate postoperative haemodynamic instability among adult surgical patients in Ethiopia, 2024: a multicentre prospective observational study.
Observational study in BMJ open, 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
objectiveThis study aimed to find the incidence and predictors of postoperative haemodynamic instability among adult surgical patients in the postanaesthesia care unit (PACU). STUDY
designA multicentre prospective observational study was conducted from 1 June to 30 September 2024.
settingThe study was conducted at three hospitals in the South Gondar Zone, north-west Ethiopia.
participantsThe study included 404 elective surgical patients undergoing surgery who were in the PACU. All adult patients who were fit, stable and underwent elective surgery under anaesthesia and were admitted to the PACU for monitoring and stabilisation were included in the study. Patients who were directly admitted to an intensive care unit or ward after an operation and those who refused to give consent were excluded from the study. OUTCOME MEASURES: The study investigates the incidence and predictors of immediate postoperative haemodynamic instability in adult surgical patients.
resultThe incidence of postoperative haemodynamic instability in the PACU was 47.8% (95% CI 43.1% to 52.5%). Multivariable logistic regression analysis shows that American Society of Anesthesiologists class III patients (adjusted OR (AOR): 3.04, 95% CI 1.48 to 6.25), patients with preoperative anxiety (AOR: 2.9, 95% CI 1.73 to 4.78), preoperative use of beta-blocker medication (AOR: 1.9, 95% CI 1.11 to 3.32), patients who experienced intraoperative haemodynamic instability (AOR: 1.8, 95% CI 1.2 to 3.14) and patients with a procedure lasting more than 4 hours (AOR: 3.7, 95% CI 3.26 to 9.67) were significantly associated with haemodynamic instability.
conclusionThe incidence of postoperative haemodynamic instability in this study was high. Our findings highlight the urgent need for hospital quality improvement initiatives and healthcare professionals assigned to the PACU should monitor the patients continuously. We also recommend that future researchers monitor the patients for 24 hours.
