About this study

Official title: Impact of Ambulatory Management for Primary Spontaneous Pneumothorax in the Emergency Department on Quality of Life: a Randomized Clinical Trial

Outpatient treatment of Primary Spontaneous Pneumothorax (PSP) compared to usual inpatient management could improve quality of care and represent a more efficient, generalizable and sustainable strategy.

This multicenter, cluster-controlled, randomized interventional study with stepped wedge implementation will evaluate the impact on quality of life (between inclusion, after drain placement, and 6 months) of an ambulatory strategy for the management of large abundance primary spontaneous pneumothorax in the emergency department, compared with usual care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ambulatory managementOther

    • Chest tube drainage in emergency department (Furhmann drain connected to Heimlich valve), connected to suction system at -5 to -10 cm H2O until bubbling stops
    • Follow-up imaging at 4 hours (chest X-ray or low-dose CT scan, depending on management practices in the centers)
    • if the pneumothorax is still very large, or if clinical tolerance is unsatisfactory (dyspnea, unrelieved pain, abnormal vital parameters), the patient should be admitted to hospital
    • if the lung is in the process of reattachment and a minimal detachment persists, and clinical tolerance is good (assessed on vital parameters, with oxygen saturation above 98%, good hemodynamic stability and pain relieved by analgesics), the patient may be discharged home.
  • Standard CareOther

    Hospitalisation in a hospital department (pulmonology, thoracic surgery, short-stay emergency unit, critical care, according to the usual pathway of the center in which the patient is included).

    In-hospital monitoring until complete resolution of pneumothorax and drain removal (average 4-6 days).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Quality of life at 6 months

    Evaluate the impact on quality of life (between inclusion, after drain placement, and 6 months) of an ambulatory strategy for the management of large abundance primary spontaneous pneumothorax in the emergency department, compared with usual care, using the Short Form (36) Health Survey (The lower the score the more disability)

    Measured: 6 months

Secondary outcomes (23)
  1. Success rate of the strategy as measured by pulmonary expansion (lung reattachment on X-ray / CT scan) the latest by the investigator who performed the drainage procedure

    Measured: Day 6

  2. Proportion of patients having benefited from an exclusive outpatient management (patients not requiring hospitalisation during the ambulatory approach)

    Measured: Day 6

  3. Assessment of Pain

    Pain assessed on a numerical scale (rated from 0 to 10), 0 being the lowest pain and 10 being the maximum pain

    Measured: Day 0, Day 2, Day 4, Day 6 and monthly

  4. Assessment of Dyspnea according to the mMRC classification

    mMRC classification (0 to 4), 0 being no discomfort and 4 shortness of breath for simple acts of daily living.

    Measured: Day 0, Day 2, Day 4, Day 6 and monthly

  5. Complication rates (major and minor) in the 2 groups

    • Minor (bleeding at insertion site, tube kinking, pain limiting inspiratory movements, subcutaneous emphysema, unsightly scar)
    • Major (hemothorax due to lesion of the vasculonervous bundle, bubbling (leakage) at the tube insertion site, accidental removal, perforation of an organ (lung, spleen, etc.), local abscess, iatrogenic pneumothorax on tube removal, pulmonary re-expansion edema).

    Measured: Day 2, 4, 6, 1 month and 1 year

  6. Pneumothorax Recurrence Rate

    Incidence of recurrence in both groups.

    Measured: at 1 year

  7. Patient satisfaction assessed by SAPS (The Short Assessment of Patient Satisfaction) questionnaire

    Measured: Day 0, 1 month, 6 months and 1 year

  8. Patient preference (coded from 0 to 5): ambulatory/non-ambulatory

    Preference will be assessed as follows: Each patient will be asked to code their opinion of outpatient management from 0 to 5, and their opinion of inpatient management from 0 to 5, whatever their randomization group (0 being the worst opinion of the strategy, and 5 a very positive opinion of the strategy).

    Measured: Day 0, 1 month, 6 months and 1 year

  9. Anxiety assessed by the State-Trait Anxiety Inventory (STAI)

    Measured: Day 0, 1 month, 6 months and 1 year.

  10. Quality of life assessed by SF-36 (The Short Form (36) Health Survey)

    Measured: at 1 month and 1 year

  11. Ambulatory strategy implementation criteria : Penetrance

    Assesses how widely the device is deployed within a service and whether it is transferable to other contexts. Studied through focus groups with professionals on adoption, institutional changes, and scalability

    Measured: At 1 year

  12. Ambulatory strategy implementation criteria : Acceptability

    Represents how patients and healthcare professionals perceive the benefits and limits of the device in care and relationships. Evaluated through semi-structured interviews (patients' experiences) and focus groups (care practices)

    Measured: At 1 year

  13. Ambulatory strategy implementation criteria : Appropriation

    Concerns the perceived added value of the device in care management and patient-professional relations. Measured via interviews (perceived value/efficacy) and focus groups (use in ambulatory vs hospital care).

    Measured: At 1 year

  14. Ambulatory strategy implementation criteria : Adoption

    Refers to whether professionals and patients integrate or learn new practices with the device. Assessed by interviews on experiences and focus groups on care practices.

    Measured: At 1 year

  15. Ambulatory strategy implementation criteria : Feasibility

    Looks at the practical experience of using the device in daily care and the caregiver-patient relationship. Explored in focus groups with healthcare professionals discussing usability and practicality.

    Measured: At 1 year

  16. Ambulatory strategy implementation criteria : Fidelity

    Examines whether the device is applied as initially intended, and the perceived quality of its implementation. Assessed through focus groups reflecting on adherence to goals and strategies in care delivery.

    Measured: At 1 year

  17. Ambulatory strategy implementation criteria : Cost of implementation

    Considers the economic impact for patients and the health system (direct and indirect costs). Evaluated through quantitative patient data: hospital stays, readmissions, and insurance compensation.

    Measured: At 1 year

  18. Ambulatory strategy implementation criteria : Durability

    Relates to maintaining the device over time and integrating it into routine care across hospitals. Evaluated via interviews (patients' risk perception, care continuity) and focus groups (staff reflection on long-term use).

    Measured: At 1 year

  19. Duration of emergency care in the 2 groups

    Measured: 1 year

  20. Estimation of costs associated with each strategy

    Total direct and indirect healthcare costs associated with each management strategy.

    Measured: at 1 year

  21. Estimation of the difference in QALYs gained using a mixed model

    Measured: at 1 year

  22. Incremental cost-utility ratio, defined as the difference in costs divided by the difference in utility estimated by the EQ-5D scores obtained by mapping from the SF-36

    with a valuation of the scores obtained with the utilities published for the French population

    Measured: at 1 year

  23. Budgetary impact of a national roll-out scenario for the ambulatory care strategy from the perspective of the French Health Insurance

    Measured: at 1 year
