Readmission after Adult Uvulopalatopharyngoplasty: A Population-Based Inpatient Cohort Study in Taiwan

OBJECTIVE

To investigate readmissions among adult inpatients who underwent uvulopalatopharyngoplasty (UPPP) in Taiwan.

DESIGN

Population-based survey.

SETTING

Retrospective study with the National Health Insurance Database.

METHODS

All cases of inpatient adult UPPP (age >20 years) from 1997 to 2012 were identified through International Classification of Diseases, Ninth Revision, Clinical Modification. Factors associated with readmission within 30 days after surgery were analyzed.

RESULTS

A total of 38,839 adults with UPPP were identified (mean age, 39.3 years; men, 73.7%). The incidence of UPPP was 14.6 per 100 000 adults, which increased from 1997 to 2012 (6.7 to 16.7 per 100,000, P_trend < .001). The rates of readmission for any reason, readmission for bleeding, reoperation for bleeding, and 30-day mortality were 4.2%, 1.7%, 1.0%, and 0.14%, respectively. Young age increased the risk of reoperation for bleeding, and old age increased the risk of readmission for any reason and mortality. Men had an increased risk of readmission and reoperation. Hypertension was associated with an increased risk of readmission for any reason (odds ratio [OR], 1.29; 95% CI, 1.10-1.51), bleeding-related readmission (OR, 1.89; 95% CI, 1.52-2.36), and reoperation (OR, 2.47; 95% CI, 1.84-3.30). Concurrent hypopharyngeal surgery was associated with an increased risk of readmission for any reason (OR, 1.34; 95% CI, 1.07-1.66) and bleeding-related readmission (OR, 1.69; 95% CI, 1.25-2.27). Finally, the use of steroids was associated with an increased risk of bleeding-related readmission and reoperation.

CONCLUSIONS

The incidence of adult UPPP increased from 1997 to 2012 in Taiwan. Age, sex, comorbidity, concurrent hypopharyngeal surgery, and drug administration were associated with readmission after inpatient UPPP.

Modified uvulopalatopharyngoplasty and coblation channeling of the tongue for obstructive sleep apnea: a multi-centre Australian trial

STUDY OBJECTIVES

To investigate the surgical outcomes and efficacy of modified uvulopalatopharyngoplasty (mod UPPP) and Coblation channelling of the tongue (CCT) as a treatment for obstructive sleep apnea (OSA).

METHODS

Adult patients with simple snoring or obstructive sleep apnea were treated with combined modified UPPP, bilateral tonsillectomy, and CCT (N = 48). Full polysomnography was performed preoperatively and 3 months postoperatively. Postoperative clinical assessment, sleep questionnaires, and patient demographics including body mass index were compared to preoperative data. All polysomnograms were re-scored to AASM recommended criteria by 2 sleep professionals.

RESULTS

The preoperative AHI (median and interquartile range) of 23.1 (10.4 to 36.6) was lowered to a postoperative AHI of 5.6 (1.9 to 10.4) (p < 0.05). The Epworth Sleepiness Scale score fell from 10.5 (5.5 to 13.5) to 5.0 (3.09 to 9.5) (p < 0.05). Morbidity of the surgery was low, with no long-term complications recorded.

CONCLUSIONS

Modified UPPP combined with CCT is a highly efficacious intervention for OSA with minimal morbidity. It should be considered for individuals who fail or are intolerant of CPAP or other medical devices.

Clinical Equipoise in Sleep Surgery

Objective. Surgical approaches for alleviating snoring and/or obstructive sleep apnea (OSA) have been questioned because of a lack of evidence from high-quality randomized controlled trials (RCTs). An ethical requirement for RCTs is that they must test questions where community equipoise (ie, uncertainty) exists as to the correct treatment. We aimed to measure perceived importance, community equipoise, and willingness to enroll patients in 5 potential trial targets among members of the Australian Society for Otolaryngology Head and Neck Surgery (ASOHNS).

Study Design, Setting, and Subjects. All ASOHNS members were surveyed using a multistage mail, email, Internet, and phone-based questionnaire.

Methods. Equipoise was measured for each of the scenarios using a bidirectional linear scale comparing 2 treatments. Responses were categorized into 1 of 3 groups: (A) preferred treatment 1, (B) completely undecided, and (C) preferred treatment 2. The resulting proportions are called equipoise ratios: A:B:C. Using tick boxes, the authors queried the general clinical importance and willingness to enroll patients for all scenarios.

Results. A total of 167 of 313 surgeons responded (53.4%). Three of the 5 trial scenarios exhibited evidence of community equipoise, but 2 scenarios, radiofrequency ablation plus uvulopalatopharyngoplasty (UPPP) versus UPPP alone and upper-airway reconstruction versus mandibular advancement splint (MAS), did not have strong support for enrolling patients. Informal feedback indicates one of these may be feasible in a smaller number of specifically trained surgeons.

Conclusion. We suggest 2 potential RCT targets: septoplasty and turbinate reduction versus conservative measures for snoring and airway reconstruction versus MAS for OSA, where importance, clinical equipoise, and willingness all exist.
