Brief Summary

An international team of experts is working on a project called PrECiSIOn to develop a clear, consistent definition of PPCs. The goals of this study are to:

  • Define postoperative pulmonary complications in a way that makes sense for patients, families, and healthcare providers.
  • Rank complications by severity so doctors can focus on the most serious ones first.
  • Decide how and when to monitor patients after surgery to catch problems early.

Outcome Measures

Primary Outcomes (1)

  • Generate consensus on the postoperative pulmonary complications construct

    A diverse group of panellists worldwide, based on pre-specified qualification criteria, will conduct iterative Delphi rounds to generate consensus on the construct of postoperative pulmonary complications.

    3-6 months

Secondary Outcomes (4)

  • Generate consensus on the postoperative pulmonary complications definition and components

    3-6 months

  • Generate consensus on the on the timeframe of monitoring for postoperative pulmonary complications

    3-6 months

  • Generate consensus on the methods of monitoring of postoperative pulmonary complications

    3-6 months

  • Generate consensus on weightage grade of individual postoperative pulmonary complications

    3-6 months

Study Arms (2)

Delphi Panellists

An international panel of 35-40 panellists from Anesthesiology, Surgery or Intensive Care Medicine and including patient representatives, will be invited to this Delphi study. A concerted effort will be made to include panellists from low- and middle-income countries and both sexes.

Other: Delphi study

Patient and Public involvement

Individuals who have either personally experienced PPCs following surgery within the last 5 years or, primary caregivers of such patients will be recruited as patient care representatives.

Other: Structured Interview

Interventions

This Delphi study involves multiple iterative rounds until a stable consensus or dissensus is reached on all the statements.

Delphi Panellists

Structured interviews will be conducted by members of the steering committee and an independent qualitative research expert. A pilot-tested case vignette along with a Likert scale-based questionnaire, will be employed to gather insights regarding the impact and severity of PPCs. The impact of the individual components of PPCs will be evaluated on a 7-point Global Rate of Change (GRC) scale (from "very much worse" to very much better") to calculate the minimal clinical important difference. Patient care representatives will be engaged in anonymous voting on the questionnaire. PPCs' rankings and key themes synthesised from the interviews will be shared with the panel in the second Delphi round, facilitating the integration of patient perspectives into the consensus process.

Patient and Public involvement

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

To encourage the continued engagement of the panellists and help prevent them from dropping out before completing the full process, at least three personalised email reminders will be sent during each Delphi round, in addition to an effort to establish personal contact. Furthermore, all panellists will be recognised as collaborative authors in the final publication in appreciation of their professional expertise. Should the attrition rate of panellists exceed 20%, a sensitivity analysis will be conducted, considering the plausible worst-case and best-case scenarios, and taking into account the opinions of non-responders.

You may qualify if:

  • At least 10 years of clinical experience as a staff member in Anesthesiology, Surgery or Intensive Care Medicine with involvement in care of patients with postoperative complications
  • Author of at least three publications (observational studies or randomised controlled trials) using postoperative pulmonary complications as a primary or secondary outcome For patients and public involvement Individuals who have either personally experienced PPCs following surgery within the last 5 years or, primary caregivers of such patients will be recruited as patient care representatives. Proficiency in English is required. To mitigate potential bias, patient care representatives mustn't maintain a professional or advisory relationship with the steering committee or panellists.

You may not qualify if:

  • \- None
