Validation of the postoperative Quality of Recovery-15 questionnaire after emergency surgery and association with quality of life at three months.

PURPOSE: The Quality of Recovery-15 (QoR-15) tool, validated for measuring postoperative recovery following scheduled surgeries, has not been psychometrically assessed in emergency contexts. Moreover, the QoR-15's associations with long-term outcomes remain underexplored. This study aimed to confirm the validity and reliability of the QoR-15 following emergency surgery and assess its association with three-month postoperative quality of life. METHODS: We conducted a prospective cohort study (August 2021-April 2022) on adult patients who underwent emergency surgery. The QoR-15 questionnaire was administered before surgery (H0) and at 24 hr (H24) and 48 hr (H48) after surgery. We examined the H24 score's associations with both the three-month quality of life, as assessed by the EQ-5D scale, and the number of days spent at home at 30 (DAH30) and 90 (DAH90) days. RESULTS: Of the 375 included patients, 352 (94%) completed the QoR-15 at H24 and 338 (90%) were followed up at three months. The population represented the following diverse surgical specialties: orthopedic (51%), gastrointestinal (27%), urologic (13%), and others (9%). The QoR-15 questionnaire confirmed all psychometric qualities (internal consistency, reproducibility, responsiveness, acceptability, construct, and convergent validities) in the emergency context. The average minimum clinical difference was 8.0 at H24. There was an association between QoR-15 at H24 and the three-month quality of life (r = 0.24; 95% confidence interval [CI], 0.14 to 0.34; P < 0.001), DAH30 (r = 0.33; 95% CI, 0.23 to 0.41; P < 0.001), and DAH90 (r = 0.31; 95% CI, 0.22 to 0.40; P < 0.001). CONCLUSION: The QoR-15 score is valid for measuring early postoperative recovery after emergency surgery. The H24 score significantly correlated with both the three-month quality of life and the number of days at home. STUDY REGISTRATION: ClinicalTrials.gov (NCT04845763); first submitted 11 April 2021.

RéSUMé: OBJECTIF: L'outil Quality of Recovery-15 (QoR-15), validé pour mesurer la récupération postopératoire après des chirurgies programmées, n'a pas fait l'objet d'une évaluation psychométrique dans des contextes d'urgence. De plus, l'association entre les réponses au QoR-15 et les devenirs à long terme demeure peu explorée. Cette étude visait à confirmer la validité et la fiabilité du QoR-15 après une chirurgie d'urgence et à évaluer son association avec la qualité de vie postopératoire à trois mois. MéTHODE: Nous avons mené une étude de cohorte prospective (août 2021-avril 2022) auprès de patient·es adultes ayant bénéficié d'une intervention chirurgicale d'urgence. Le questionnaire QoR-15 a été administré avant la chirurgie (H0), ainsi que 24 (H24) et 48 heures (H48) après la chirurgie. Nous avons examiné les associations du score à H24 avec la qualité de vie à trois mois, telle qu'évaluée par l'échelle EQ-5D, et le nombre de jours passés à la maison à 30 (DAH30) et 90 (DAH90) jours. RéSULTATS: Sur les 375 patient·es inclus·es, 352 (94 %) ont complété le QoR-15 à H24 et 338 (90 %) ont bénéficié d'un suivi à trois mois. La population représentait les diverses spécialités chirurgicales suivantes : orthopédique (51 %), gastro-intestinale (27 %), urologique (13 %) et autres (9 %). Le questionnaire QoR-15 a confirmé toutes les qualités psychométriques (cohérence interne, reproductibilité, réactivité, acceptabilité, construit et validités convergentes) dans le contexte de l'urgence. La différence clinique minimale moyenne était de 8,0 à H24. Il y avait une association entre le QoR-15 à H24 et la qualité de vie à trois mois (r = 0,24; intervalle de confiance à 95 % [IC], 0,14 à 0,34; P < 0,001), le DAH30 (r = 0,33; IC 95 %, 0,23 à 0,41; P < 0,001) et le DAH90 (r = 0,31; IC 95 %, 0,22 à 0,40; P < 0,001). CONCLUSION: Le score QoR-15 est valable pour mesurer la récupération postopératoire précoce après une intervention chirurgicale d'urgence. Le score à H24 était significativement corrélé à la fois à la qualité de vie à trois mois et au nombre de jours passés à la maison.

Oesophageal pressure monitoring in intubated patients by intensive care units' nurses: An educational study.

Trained ICU nurses may perform oesophageal pressure measurements which may help facilitate its implementation in the usual patient care to better assess lung and chest wall mechanics and easily detect patient-ventilator asynchronies. We thus conducted a prospective educational study aiming to assess the ability of ICU nurses to perform reliable oesophageal pressure measurements after a short dedicated training program. All the 11 nurses who completed the program succeeded their practical evaluation (nine (82%) at the first evaluation and two (18%) at their second attempt). These results show that this training program is feasible and that trained ICU nurses can perform accurate oesophageal pressure measurements in mechanically ventilated patients.

Advanced respiratory mechanics assessment in mechanically ventilated obese and non-obese patients with or without acute respiratory distress syndrome.

BACKGROUND: Respiratory mechanics is a key element to monitor mechanically ventilated patients and guide ventilator settings. Besides the usual basic assessments, some more complex explorations may allow to better characterize patients' respiratory mechanics and individualize ventilation strategies. These advanced respiratory mechanics assessments including esophageal pressure measurements and complete airway closure detection may be particularly relevant in critically ill obese patients. This study aimed to comprehensively assess respiratory mechanics in obese and non-obese ICU patients with or without ARDS and evaluate the contribution of advanced respiratory mechanics assessments compared to basic assessments in these patients. METHODS: All intubated patients admitted in two ICUs for any cause were prospectively included. Gas exchange and respiratory mechanics including esophageal pressure and end-expiratory lung volume (EELV) measurements and low-flow insufflation to detect complete airway closure were assessed in standardized conditions (tidal volume of 6 mL kg-1 predicted body weight (PBW), positive end-expiratory pressure (PEEP) of 5 cmH2O) within 24 h after intubation. RESULTS: Among the 149 analyzed patients, 52 (34.9%) were obese and 90 (60.4%) had ARDS (65.4% and 57.8% of obese and non-obese patients, respectively, p = 0.385). A complete airway closure was found in 23.5% of the patients. It was more frequent in obese than in non-obese patients (40.4% vs 14.4%, p < 0.001) and in ARDS than in non-ARDS patients (30% vs. 13.6%, p = 0.029). Respiratory system and lung compliances and EELV/PBW were similarly decreased in obese patients without ARDS and obese or non-obese patients with ARDS. Chest wall compliance was not impacted by obesity or ARDS, but end-expiratory esophageal pressure was higher in obese than in non-obese patients. Chest wall contribution to respiratory system compliance differed widely between patients but was not predictable by their general characteristics. CONCLUSIONS: Most respiratory mechanics features are similar in obese non-ARDS and non-obese ARDS patients, but end-expiratory esophageal pressure is higher in obese patients. A complete airway closure can be found in around 25% of critically ill patients ventilated with a PEEP of 5 cmH2O. Advanced explorations may allow to better characterize individual respiratory mechanics and adjust ventilation strategies in some patients.

Postoperative transfusion hemoglobin threshold and functional recovery after high-risk oncologic surgery: A randomized controlled pilot study.

BACKGROUND: Robust evidence to inform best transfusion management after major oncologic surgery, where postoperative recovery might impact treatment regimens for cancer, is lacking. We conducted a study to validate the feasibility of a larger trial comparing liberal versus restrictive red blood cells (RBC) transfusion strategies after major oncologic surgery. STUDY DESIGN AND METHODS: This was a two-center, randomized, controlled, study of patients admitted to the intensive care unit after major oncologic surgery. Patients whose hemoglobin level dropped below 9.5 g/dL, were randomly assigned to immediately receive a 1-unit RBC transfusion (liberal) or delayed until the hemoglobin level dropped below 7.5 g/dL (restrictive). The primary outcome was the median hemoglobin level between randomization to day 30 post-surgery. Disability-free survival was evaluated by the WHODAS 2.0 questionnaire. RESULTS: 30 patients were randomized (15 patients/group) in 15 months with a mean recruitment rate of 1.8 patients per month. The median hemoglobin level was significantly higher in the liberal group than in the restrictive group: 10.1 g/dL (IQR 9.6-10.5) versus 8.8 g/dL (IQR 8.3-9.4), p < .001, and RBC transfusion rates were 100% versus 66.7%, p = .04. The disability-free survival was similar between groups: 26.7% versus 20%, p = 1. DISCUSSION: Our results support the feasibility of a phase 3 randomized controlled trial comparing the impact of liberal versus restrictive transfusion strategies on the functional recovery of critically ill patients following major oncologic surgery.

Early quality of recovery according to QoR-15 score is associated with one-month postoperative complications after elective surgery.

STUDY OBJECTIVE: The QoR-15 scale is a validated tool to assess the quality of postoperative recovery (QoR). Our objective was to assess the association between the early QoR-15 values and the occurrence of one-month postoperative complications. DESIGN: We used the data from a prospective single-centre cohort study conducted in the Angers University Hospital from July 2019 to February 2020 that validated the French version of the QoR-15 (FQoR-15). SETTING: Preoperative room, ward, and home. PATIENTS: 363 French-speaking adult patients, undergoing elective surgery, were enrolled (217 (59,8%) men, median age 60 (range 44 to 71) years old), including 139 (38.3%) ambulatory surgeries. INTERVENTION: Patients completed the QoR-15 scale the day before, at 24 and 48 h after surgery. MEASUREMENTS: Postoperative complications were recorded according to the PostOperative Morbidity Survey (POMS) classification till 30 days after surgery. The QoR was classified as excellent (QoR-15 > 135), good (122 ≤ QoR-15 ≤ 135), moderate (90 ≤ QoR-15 ≤ 121) or poor (QoR-15 < 90). Days alive and out of hospital up to 30 days after surgery was also recorded. MAIN RESULTS: According to the POMS classification, 176 (48.5%) patients had at least one complication up to 30 days after surgery. Among the 69 (19.0%) patients with a poor recovery at H24, 58 (84.1%) had at least one complication up to 30 days after surgery compared to 10 (23.8%) among the 42 (11.6%) in the excellent recovery group (p < 0.0001). The QoR-15 score at H24 allowed suitable discrimination of the occurrence of at least one complication up to 30 days after surgery (AUC 0.732 (95% CI 0.680 to 0.784)). CONCLUSION: The early QoR-15 scale after surgery is moderately associated with the occurrence of postoperative complications up to 30 days after elective surgeries (i.e. it has predictive validity).
