Among the 56 studies in Pain, Postoperative with a site in Brazil, from their registry updates:
Nothing recorded among them since 2026-09-25.
After surgery, doctors need to know how patients are doing, especially in the first hours after they leave the recovery room. This can be hard to track once patients go to a regular hospital room, and some symptoms - like pain or nausea - may go unnoticed.
This study tests whether an online form, sent to patients' phones, can help doctors check on pain and recovery in the first 12 and 24 hours after surgery. Patients (or a family member helping them) will receive a link by WhatsApp and answer a short set of questions about their pain, nausea, medications, and how they are recovering.
The main goal is to find out whether patients are willing and able to use this online form, and whether it is a helpful and practical way to follow up with them after surgery.
Postoperative recovery is a dynamic process requiring continuous monitoring. After discharge from the post-anesthesia care unit (PACU), patients are typically assessed only through periodic in-person visits by the ward staff, which can create gaps in surveillance and lead to underreporting of pain, nausea, and other symptoms during the immediate postoperative period. Digital tools have been proposed as a way to narrow this gap by allowing patients to report symptoms directly and continuously, potentially enabling earlier identification of complications and more timely clinical response.
Despite promising results from international studies on postoperative digital monitoring, reviews have identified important gaps, including methodological heterogeneity, a lack of standardized and validated instruments, and limited integration with clinical teams. There is a particular scarcity of studies evaluating simple, accessible digital tools for the immediate postoperative period in Brazilian public hospitals.
This pilot study was designed to address that gap by testing a simplified, purpose-built digital form for remote postoperative follow-up. During the pre-anesthetic evaluation, patients (or an accompanying caregiver, when needed) are given a link, sent via WhatsApp, to a web-responsive online questionnaire designed for ease of use among postoperative patients. The form includes 18 questions covering pain at rest and during movement, nausea and vomiting, use of rescue analgesics and antiemetics, need for anesthesiology team intervention, functional recovery (ability to urinate and defecate), and overall satisfaction with the recovery process and with the questionnaire itself. Patients are asked to complete the form at two time points: 12 and 24 hours after PACU discharge.
The study's central hypothesis is that a simplified digital form is a feasible and well-accepted tool for remote postoperative monitoring, and that it can capture clinically meaningful data on pain, adverse effects, and perceived recovery. Findings from this pilot are intended to inform the future development of digital follow-up protocols - including potential integration with electronic medical records - for postoperative care in Brazilian public hospital settings, and to identify barriers to more equitable implementation of remote monitoring tools.
Adult patients undergoing elective surgery not intended for postoperative intensive care unit (ICU) admission, consecutively enrolled at a single tertiary public hospital in the Federal District, Brazil. Patients are approached during the pre-anesthetic evaluation and, if eligible and willing to participate, are followed remotely via a digital form during the first 24 hours after discharge from the post-anesthesia care unit (PACU).

Adult patients (≥18 years) undergoing elective, non-ICU-bound surgery at a tertiary public hospital, who completed a digital web-based form to report pain, nausea/vomiting, medication use, functional recovery, and satisfaction at 12 and 24 hours after PACU discharge.
Other: Digital web-based postoperative follow-up form
A responsive, 18-item online questionnaire, accessed via a WhatsApp link, used to remotely collect patient-reported data on pain, nausea/vomiting, medication use, functional recovery, and satisfaction at 12 and 24 hours after PACU discharge. This is a data-collection tool and does not constitute a clinical/therapeutic intervention.
Adherence Rate to the Digital Follow-up Form
Proportion of enrolled patients who fully completed the digital questionnaire, calculated separately at 12 and 24 hours after discharge from the post-anesthesia care unit (PACU).
Time frame: At 12 hours and at 24 hours after PACU discharge
Plan to share: Undecided — A decision regarding individual participant data sharing has not yet been made. Data are currently stored on a secure digital platform with restricted access limited to the research team, in accordance with the approved research protocol. Any future data-sharing plan will comply with applicable Brazilian data protection and research ethics regulations (Law No. 14,874/2024; CNS Resolution No. 466/2012) and will be submitted for review by the Research Ethics Committee (CEP/IGESDF) before implementation.
Start is estimated for Oct 2026; primary completion for Sep 2027, 11 months later.
Of 391 non-industry observational studies under Pain, Postoperative, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 32. This study's planned 11 months is below that.
Counting every sponsor, half of 395 studies reached it within 13 months; a quarter within 5 and three quarters within 33.
