Postoperative Pain, Why Still in Hospital and DAOH Following TORS for SCCUP & OSAS
An Investigation of Postoperative Pain, Why Still in Hospital and Days Alive and Out of Hospital Following Transoral Robotic Surgery for Squamous Cell Carcinoma of Unknown Primary and Obstructive Sleep Apnea
This protocol investigates the effect of a high dose dexamethasone regimen in the treatment of postoperative pain following Transoral Robotic Surgery (TORS). The protocol consists of three substudies.
- Randomized double-blinded clinical trial assigning half of the participants to a high-dose dexamethasone regimen while the other half will receive a low-dose dexamethasone dosage and placebo in the first postoperative period.
- A investigation of "Why in hospital?" following TORS. From the first postoperative day until discharge reasons for continued hospitalization will be registered in order to identify clinical and organizational factors contributing to hospitalization
- An assessment of "Days Alive and Out of Hospital" following TORS. From the day of surgery and the first 12 postoperative months all admissions to a hospital ward will be registered along with admission reasons. Any death during the first 12 months will be noted with a cause of death.

Detailed Description
The morbidity after TORS has not yet been fully investigated, but a recent studies suggest that pain is one of the primary causes for unplanned readmission This issue has been investigated by Clayburgh D et al who found that a prolonged dexamethasone regime lowered the pain scores on day three after surgery. The patients treated with the prolonged dexamethasone regime also showed a significant improvement in the food consistency they were capable to swallow and had a shortened length of stay (LOS). Recently, a pilot-study showed, that an intensified dexamethasone regime among TORS patients reduced the pain level to that of a standard tonsillectomy. Besides an analgesic effect glucocorticoids furthermore poses an anti-inflammatory quality which can be used to lower the physiological stress and inflammatory response following surgery and may prevent organ dysfunctions and complications The analgesic effect of dexamethasone has been the topic of many clinical studies, and are well described in various surgical fields. However, the optimal dose and regime for glucocorticoids prescription has so far not been established. The evidence favoring one dosage regime and an optimal prescribed dose is restricted by the variance in the regimes used in various clinical trials and the fact that there is a need for clinical trial investigating steroids with pain as the primary endpoint Consequently, it is important to thoroughly investigate and optimize the analgesic regime after TORS.
Hospitalization So far when evaluating the long-term consequences of TORS, the main focus has been on oncological outcomes and quality of life with attention to functional outcomes, i.e. feeding tube dependency and dysphagia while the LOS following TORS and why the patient is hospitalized after the procedure have been sparsely studied.
The reason why TORS patients are still hospitalized after the procedure and which clinical and organizational factors contribute to the hospitalization have not yet been examined and understood but is highly relevant in order to understand and improve the postoperative care.
A method to assess the efficiency of a therapy have emerged from the cardiology field and is called Days Alive and Out of Hospital (DAOH). This has been used in investigations of heart failure patients and myocardial infarction patients. This outcome combines mortality and morbidity, and accounts for the number but also duration of several hospitalizations after the primary discharge.
DAOH has only sparse been used in the surgical field, and only in few studies in the cardiac surgery area. The measurement is a patient-centered outcome that provide better information to the patient and surgeon when planning surgery, and can be used for quality improvement studies since it accounts for effective and efficient care.
Therefore, the DAOH measurement applied to the evaluation of TORS treatment for SCCUP will benefit the insight in how the patient's life after treatment is affected.
The aims of this study comprising patients treated with TORS for SCCUP:
- To lower the patients pain intensity after the TORS procedure with an intensified dexamethasone regimen.
- To investigate the clinical and organizational factors contributing to hospitalization after TORS, and with this knowledge to establish an optimized postoperative care program.
- To measure the efficiency and morbidity after TORS using DAOH as a descriptive assessment 12 months postoperatively.
This project consists of four studies:
Study 1 - Corresponding to aim A. The investigators hypothesize that an intensified dexamethasone regime will lower patients' reported pain intensity following TORS. This will be investigated in a randomized (1:1) double-blinded clinical trial among SCCUP patients undergoing TORS and extrapolated to the entire TORS population.
- A routine surgical complications study will be performed and examine surgical complications within the first 30 postoperative days.
Study 2 - Corresponding to aim B The investigators hypothesize that not much is known about the precise reasons for why patients are hospitalized following TORS. Hence, a prospective observational study regarding "why still in hospital after TORS?" will be conducted among all patients with SCCUP scheduled for TORS.
Study 3 - Corresponding to aim C The investigators hypothesize that TORS is an efficient procedure with a low morbidity. Hence, a prospective observational study regarding DAOH will be conducted among all SCCUP patients scheduled for TORS.

Patient-reported Pain intensity
Time Frame: Postoperative day 1 until day 14 postoperatively
|
Visual analog scale (VAS) ranging from 0-10.
0 being no pain and 10 being maximum pain.
The patient will twice daily self-assess pain-intensity during both rest and activity (swallowing).
The pain-intensity will be noted in a pain-diary
|

Time Frame |
---|---|---|
Why in hospital
Time Frame: Postoperative day 1 until discharge
|
A functional discharge criteria scheme will be used twice daily at 9 a.m. and 2 p.m. (± 2 hours) to decide whether the patient can be discharged.
The scheme will be filled out by a doctor and/or nurse and used until discharge from the ward.
This is an assessment of organizational and clinical factors contributing to hospitalization
|
Postoperative day 1 until discharge
|
Days Alive and Out of Hospital
Time Frame: From the day of surgery and the first 12 postoperative months
|
Days alive and out of hospital is a composite patient-centered endpoint.
It is calculated by deducting the length of stay of the initial admission as well as any subsequently admissions and days after potential death from the total follow-up period.
Days Alive and Out of Hospital will be investigated from the day of surgery with a 12 months follow-up period.
