This study combines retrospective data analysis with a single-center prospective non-interventional cohort study to understand postoperative sleep disturbance on the first night after video-assisted thoracoscopic (VATS) lobectomy or segmentectomy. It mainly wants to answer the question: Can perioperative data collected along the clinical timeline dynamically predict which patients will experience clinically significant sleep disturbance on their first postoperative night? Participants undergoing elective VATS lung resection will have multidimensional data systematically collected from preoperative screening (including PSQI and GAD-7), intraoperative anesthetic parameters, PACU-to-ward handover, pre-bedtime symptom burden, and follow-up through 1 month. Three dynamic prediction models (M0 preoperative screening, M1 early postoperative update, and M2 pre-bedtime main model) will be developed using logistic regression with RCSQ-assessed sleep disturbance as the primary outcome, while an explanatory model will quantify the impact of nighttime disruptions such as intravenous infusions, vital sign monitoring, nursing entries, and awakenings.
This study combines retrospective data analysis with a single-center prospective non-interventional cohort study. The primary data collection is prospective, while retrospective data may be used for preliminary analysis or baseline comparison.

Counted across the registry records on this site, refreshed daily.
Adults aged 18 years and older undergoing elective video-assisted thoracoscopic (VATS) lobectomy or segmentectomy within a single-center thoracic surgery perioperative care pathway. Participants are drawn from the routine inpatient population managed under standard enhanced recovery after surgery (ERAS) protocols, with planned postoperative admission to a general thoracic ward, ASA physical status I-III, capacity to understand and complete study questionnaires, and willingness to provide informed consent. The population encompasses the perioperative window from preoperative assessment through PACU recovery to the first postoperative night.

- Aged 18 years or older; Scheduled for elective video-assisted thoracoscopic surgery (VATS) lobectomy or segmentectomy; Planned postoperative admission to a general thoracic surgery ward; (ASA) physical status classification I-III; Capable of understanding questionnaires and verbal communication; Prospective cohort participants who voluntarily enroll in the study and provide written .
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Procedure: Video-assisted thoracoscopic (VATS) lobectomy or segmentectomy
Standard elective video-assisted thoracoscopic (VATS) lobectomy or segmentectomy with general anesthesia and one-lung ventilation, performed according to routine institutional protocols. This is an observational study; no experimental modification is made to the surgical procedure, anesthetic management, or postoperative care. Patients receive standard thoracic ERAS care including analgesia, chest tube management, and vital sign monitoring. The procedure provides the clinical context for prospective perioperative data collection to develop dynamic prediction models for first-night sleep disturbance and analyze ward workflow impacts.
Clinically significant postoperative sleep disturbance on the first night after VATS lobectomy or segmentectomy
Clinically significant postoperative sleep disturbance (PSD) assessed by the Richards-Campbell Sleep Questionnaire (RCSQ) on postoperative day 1 morning. RCSQ contains 5 items (sleep depth, latency, awakenings, return to sleep, overall quality) scored 0-100; total score is the mean (higher=better). PSD defined as RCSQ total ≤50. First postoperative night: from PACU return to 06:00 next day (or actual return time if after 22:00). One missing item: mean of remaining four; ≥2 missing or inability to complete due to delirium/cognitive/communication barriers: invalid.
Time frame: From PACU return to the general thoracic ward until 06:00 on postoperative day 1, assessed on the morning of postoperative day 1
