Factors determining length of the postoperative hospital stay after major head and neck cancer surgery

Development and validation of a novel nomogram model for identifying risk of prolonged length of stay among patients receiving free vascularized flap reconstruction of head and neck cancer

Background

The aim of the present study was to build and internally validate a nomogram model for predicting prolonged length of stay (PLOS) among patients receiving free vascularized flap reconstruction of head and neck cancer (HNC).

Methods

A retrospective clinical study was performed at a single center, examining patients receiving free vascularized flap reconstruction of HNC from January 2011 to January 2019. The variables were obtained from the electronic information system. The primary outcome measure was PLOS. Univariate and multivariate analyses were used to find risk factors for predicting PLOS. A model was then built according to multivariate results. Internal validation was implemented via 1000 bootstrap samples.

Results

The study included 1047 patients, and the median length of stay (LOS) was 13.00 (11.00, 16.00) days. Multivariate analysis showed that flap types ((radial forearm free flap (odds ratio [OR] = 2.238; 95% CI, 1.403-3.569; P = 0.001), free fibula flap (OR = 3.319; 95% CI, 2.019-4.882; P < 0.001)), duration of surgery (OR = 1.002; 95% CI, 1.001-1.003; P = 0.004), postoperative complications (OR = 0.205; 95% CI, 0.129-0.325; P = P < 0.001) and unplanned reoperation (OR = 0.303; 95% CI, 0.140-0.653; P = 0.002) were associated with PLOS. In addition to these variables, blood transfusion was comprised in the model. The AUC of the model was 0.78 (95% CI, 0.711-0.849) and 0.725 (95% CI, 0.605-0.845) in the primary and internal validation cohorts, respectively. The DCA revealed the clinical utility of the current model when making intervention decisions within the PLOS possibility threshold range of 0.2-0.8.

Conclusions

Our study developed a nomogram that exhibits a commendable level of accuracy, thereby aiding clinicians in assessing the risk of PLOS among patients receiving free vascularized flap reconstruction for HNC.

Postoperative infections associated with microvascular free flaps in head and neck reconstruction: Analysis of risk factors and results with a standardized prophylaxis protocol

Currently, large defects of the head and neck regions are mainly reconstructed using microvascular free flap. Postoperative infections, including surgical site infections (SSIs) and medical postoperative infections (MPI), are important causes of morbidity and worsening of surgical outcomes. The authors aimed to analyze the results obtained using a standardized prophylaxis protocol in a series of 100 consecutive patients who underwent microvascular reconstruction surgery between 2016 and 2021 at a single institution, to identify the risk factors, which could be overcome, to minimize the incidence of infectious complications. In this study, 24 patients developed infectious complications. Higher American Society of Anesthesiologists (ASA) score was statistically associated with higher risk of infectious complications (p = 0.01), need for postoperative transfusions (p = 0.01), and higher T and N stage (p = 0.03 and p = 0.02, respectively) in patients with cancer. We also found a correlation between the increase in surgery duration, hospitalization, and intensive care unit (ICU) stay with higher risk of infection (p = 0.03, p = 0.01, and p = 0.001, respectively). Nine patients reported partial or total flap necrosis and in this group of patients, a higher incidence of infectious complication was recorded (p = 0.001). Our experience shows that SSIs and MPIs affect the global and surgical outcomes of patients and both their incidences can be reduced by correcting potential risk factors preoperatively (e.g., anemia), intraoperatively (amount of blood loss and duration of surgery), and postoperatively (duration of hospitalization and ICU stay and early elimination of potential sources of infection).

Hypothyroidism as an Independent Predictor of 30-day Readmission in Head and Neck Cancer Patients

OBJECTIVES

To define the role of hypothyroidism and other risk factors for unplanned readmissions after surgery for head and neck cancer.

STUDY DESIGN

Retrospective cohort study.

METHODS

The Nationwide Readmission Database (NRD) was used to identify patients who underwent surgery for mucosal head and neck cancer (oral cavity, oropharynx, larynx, and hypopharynx) between 2010 and 2017. Univariate and multivariate logistic regression were performed to determine patient, tumor, and hospital related risk factors for 30-day readmission. Readmitted patients were stratified by preoperative diagnosis of hypothyroidism to compare readmission characteristics.

RESULTS

For the 131,013 patients who met inclusion criteria, the readmission rate was 15.9%. Overall, 11.91% of patients had a preoperative diagnosis of hypothyroidism. After controlling for other variables, patients with a preoperative diagnosis of hypothyroidism had 12.2% higher odds of readmission compared to those without hypothyroidism (OR: 1.12, 1.03-1.22, p = 0.008). Patients with hypothyroidism had different reasons for readmission, including higher rates of wound dehiscence, fistula, infection, and electrolyte imbalance. Among readmitted patients, the length of stay for index admission (mean 10.5 days vs. 9.2 days, p < 0.001), readmission (mean 7.0 vs. 6.6 days, p = 0.05), and total hospital charge were higher for hypothyroid patients ($137,742 vs. $119,831, p < 0.001).

CONCLUSION

Hypothyroidism is an independent risk factor for 30-day readmission following head and neck cancer resection. Furthermore, hypothyroid patients are more likely to be readmitted for wound complications, infection, and electrolyte imbalance. Targeted interventions should be considered for hypothyroid patients to decrease readmission rates and associated patient morbidity, potentially leading to earlier initiation of adjuvant treatment.

Airway Management of Orofacial Infections Originating in the Mandible

The primary aim of this study was to assess the incidence of a difficult airway and emergency tracheostomy in patients with orofacial infections originating in the mandible, and a secondary aim was to determine the potential predictors of difficult intubation. This retrospective single-center study included all patients who were referred between 2015 and 2022 with an orofacial infection originating in the mandible and who were surgically drained under intubation anesthesia. The incidence of a difficult airway regarding ventilation, laryngoscopy, and intubation was analyzed descriptively. Associations between potential influencing factors and difficult intubation were examined via multivariable analysis. A total of 361 patients (mean age: 47.7 years) were included in the analysis. A difficult airway was present in 121/361 (33.5%) patients. Difficult intubation was most common in patients with infections of the massetericomandibular space (42.6%), followed by infections of the mouth floor (40%) and pterygomandibular space (23.5%). Dyspnea and stridor were not associated with the localization of infection (p = 0.6486/p = 0.4418). Multivariable analysis revealed increased age, restricted mouth opening, higher Mallampati scores, and higher Cormack-Lehane classification grades as significant predictors of difficult intubation. Higher BMI, dysphagia, dyspnea, stridor and a non-palpable mandibular rim did not influence the airway management. Patients with a difficult airway were more likely to be admitted to the ICU after surgery than patients with regular airway were (p = 0.0001). To conclude, the incidence of a difficult airway was high in patients with orofacial infections originating in the mandible. Older age, limited mouth opening, a higher Mallampati score, and a higher Cormack-Lehane grade were reliable predictors of difficult intubation.

Infusion management associated with prolonged length of stay following free flap reconstruction of head and neck defects: A propensity score matching study

BACKGROUND

Surgical resection of the primary lesion and reconstruction of the defects with free flaps are common treatments for head and neck cancer (HNC). However, various variables can lead to prolonged length of stay (LOS). The aim of this study is to investigate risk factors correlated with prolonged LOS following free flap reconstruction of head and neck defects.

METHODS

A retrospective study of patients with all types of free flaps reconstruction of HNC between January 2011 and January 2019 at Sun Yat-sen Memorial Hospital was performed. We recorded predictive variables and divided them into: personal and clinical, hemodynamic, anesthetic and surgical. The primary endpoint was prolonged length of stay. Univariate and multivariate analyses were applied to identify risk factors that associated with prolonged LOS. Propensity score matching was performed with the identified risk variables and other perioperative factors that may impact transfusion decision to explore the independent influence of intraoperative blood transfusion on prolonged LOS.

RESULTS

A total of 1047 patients were included in this study. The median LOS was 13.00 (11.00, 16.00) days. Multivariate analysis suggested that blood transfusion, duration of surgery, postoperative complications and unplanned reoperation were associated with prolonged LOS. After propensity score matching, unnecessary blood transfusion and inadequate fluid rate over 24 h, postoperative complications and unplanned reoperation were identified risk factors that led to prolonged LOS.

CONCLUSION

Unnecessary blood transfusion and inadequate fluid infusion rate over 24 h were independent risk factors associated with prolonged LOS in HNC patients who underwent free flap reconstruction. Our results indicated consideration of restrictive blood transfusion and adequate fluid infusion over postoperative 24 h in these patients.

Synchrony in head and neck surgery: Feasibility and outcomes of simultaneous scapular free flap reconstruction

BACKGROUND

The scapula free flap is a versatile option in head and neck reconstruction but is less amenable to simultaneous harvest and ablation.

METHODS

Retrospective series (2015-2021) of consecutive scapula flaps. Cases categorized as simultaneous versus sequential, compared for operative time, oncological and patient-reported outcomes.

RESULTS

Seventy consecutive scapula free flaps were performed (n = 21 simultaneous, n = 49 sequential). Mandible reconstruction was performed in 51.0% and 61.9% of sequential and simultaneous cases, respectively; 49.0% and 38.1% addressed bony maxillary defects. Simultaneous surgery reduced operative time by 37.9% (151 min, p < 0.00001) and there were fewer tracheostomies performed (p < 0.005). Rates of positive margins and free flap compromise were equivalent (n = 1, 4.8% vs. n = 2, 4.1%). There was no difference in patient-reported outcomes.

CONCLUSIONS

This series demonstrates feasibility, efficacy, and outcomes of bony scapula reconstruction of maxillofacial defects comparing simultaneous and sequential approaches. Benefits of the two-team approach are highlighted including decreased operative time.

The Utility of Comorbidity Indices in Assessing Head and Neck Surgery Outcomes: A Systematic Review

OBJECTIVE

To evaluate the utility of comorbidity index (CI) scores in predicting outcomes in head and neck surgery (HNS). The CIs evaluated were the Charlson Comorbidity Index (CCI), Elixhauser Comorbidity Index (ECI), Kaplan-Feinstein Index (KFI), American Society of Anesthesiologists Physical Status (ASA-PS), Adult Comorbidity Evaluation-27 (ACE-27), National Cancer Institute Comorbidity Index (NCI-CI), and the Washington University Head and Neck Comorbidity Index (WUHNCI).

METHODS

We report a systematic review according to the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Electronic databases (PubMed, Cochrane, and Embase) and manual search of bibliographies identified manuscripts addressing how CI scores related to HNS outcomes.

RESULTS

A total of 116 studies associated CI scores with HNS outcomes. CIs were represented in the literature as follows: ASA-PS (70/116), CCI (39/116), ACE-27 (24/116), KFI (7/116), NCI-CI (3/116), ECI (2/116), and WUHNCI (1/116). The most frequently cited justification for calculating each CI (if provided) was: CCI for its validation in other studies, ACE-27 for its utility in cancer patients, and ECI for its comprehensive design. In general, the CCI and ACE-27 were predictive of mortality in HNS. The ECI was most consistent in predicting >1-year mortality. The ACE-27 and KFI were most consistent in predicting medical complications.

CONCLUSION

Despite inconsistencies in the literature, CIs provide insights into the impact of comorbidities on outcomes in HNS. These scores should be employed as an adjunct in the preoperative assessment of HNS patients. Comparative studies are needed to identify indices that are most reliable in predicting HNS outcomes.

Long-Term Opioid Use in Post-Surgical Management of Patients With Head and Neck Cancer

OBJECTIVE

This study aims to identify clinical and socioeconomic factors associated with long-term, post-surgical opioid use in the head and neck cancer population.

METHODS

A single center retrospective study was conducted including patients diagnosed with head and neck cancer between January 1, 2014 and July 1, 2019 who underwent primary surgical management. The primary outcome measure was continued opioid use 6 months after treatment completion. Both demographic and cancer-related variables were recorded to determine what factors were associated with prolonged opioid use. Univariate analysis was performed using chi-squared test for categorical variables and 2-sample t-test for continuous variables. Multivariate analysis was performed using logistic regression.

RESULTS

A total of 359 patients received primary surgical management. Forty-five patients (12.53%) continued to take opioids 6 months after treatment completion. Using univariate analysis, patients less than 65 years of age (P = .0126), adjuvant chemoradiation (n = 25, P < .001), and overall length of hospital stay (8.60 ± 8.58 days, P = .0274) were significantly associated with long term opioid use. Multivariate logistic regression showed that adjuvant chemoradiation (OR = 3.446, 95% CI [1.742, 6.820], P = .0004) and overall length of hospital stay (OR = 0.949, 95% CI [0.903, 0.997], P = .0373) to be significantly associated with opioid use 6 months after head and neck cancer treatment.

CONCLUSION

Long-term postoperative opioid use in head and neck cancer patients is significantly associated with adjuvant chemoradiation, and patients with longer length of hospital stay. Therefore, future research should focus on interventions to better manage opioid use during the acute treatment period to decrease long-term use.

Analysis of hospitalization costs and length of stay for oral cancer patients undergoing surgery: Evidence from Hunan, China

OBJECTIVE

To provide information about hospitalization costs and length of stay (LOS) for inpatients undergoing oral cancer (OC) surgery, and to investigate the association of hospitalization costs and LOS with demographics, tumor subsite, surgery-related and hospital characteristics.

METHODS

Data extracted from Chinese National Health Statistics Network Reporting System database in Hunan, China during 2017-2019 were analyzed using quantile regression models.

RESULTS

A total of 6,420 OC patients undergoing surgery were identified. After controlling potential compounding variables, the median hospitalization cost was significantly higher in male than in female patientsby $515.70 at the median (p < 0.001). Patients aged over 60 hadsignificantly less costs by $294.85 at the meanthan did those below 60, while no differenceof LOS existed across age. OC patients with neck dissection had significantly higher costs by $1,983.33 at the median than those without (P < 0.001). Regional flaps were the most economical, with lower costs than free flaps by $3,084 (P < 0.001) and the pectoralis major myocutaneous flap (PMMF) by $549.45 (P < 0.001) at the median.

CONCLUSION

Male is a significant driver of hospitalization costs and LOS for OC, and age over 60 is associated with lower costs, but not with LOS. Mouth primary site is associated with the highest costs and LOS, while lip primary site the lowest. Absence of neck dissection in early-stage OC can significantly reduce costs and LOS, but its oncological validity needs more evidence. Regional flaps are less expensive than free flaps and the PMMF for oral reconstruction, and are recommended in select patients.

Association between perioperative chlorhexidine oral care and postoperative pneumonia in non-cardiac surgical patients: A systematic review and meta-analysis

BACKGROUND

Postoperative pneumonia is the third most common complication after surgery, and its occurrence is associated with a poor prognosis in patients. Perioperative chlorhexidine oral care has been reported to reduce the incidence of postoperative pneumonia in patients undergoing cardiac surgery. However, whether perioperative chlorhexidine oral care can reduce the incidence of postoperative pneumonia in noncardiac surgical patients is still unknown. The aim of this systematic review and meta-analysis was to determine the association between perioperative chlorhexidine oral care and postoperative pneumonia in noncardiac surgical patients.

METHODS

A comprehensive systematic search of PubMed, Ovid Embase, Web of Science, the Cochrane Library, Wanfang Database, and the China National Knowledge Infrastructure was conducted to include studies from the inception of each database through March 2021. The reference lists of all included studies were also searched by hand. Eligible studies were published and unpublished randomized controlled trials and observational studies evaluating the effect of perioperative chlorhexidine oral care on the reported incidence of postoperative pneumonia. Relative risks or odds ratio with their 95% confidence intervals were calculated and risk of bias was assessed for eligible studies.

RESULTS

Seven randomized controlled trials with a total of 1,773 patients and 3 observational studies with a total of 12,528 noncardiac surgical patients were included. A total of 621 and 5,904 patients received perioperative chlorhexidine oral care in randomized controlled trials and observational studies, respectively. Six (85%) randomized controlled trials had a high risk of bias, and 2 (67%) observational studies had a high quality. Perioperative chlorhexidine oral care significantly reduced the incidence of postoperative pneumonia in randomized controlled trials (relative risk, 0.60; 95% confidence interval, 0.44-0.80; P < .001) and observational studies (odds ratio, 0.26; 95% confidence interval, 0.08-0.90; P = .03).

CONCLUSION

Perioperative chlorhexidine oral care led by a nurse significantly decreases the incidence of postoperative pneumonia in noncardiac surgical patients and may be more convenient and economical compared with dental professional-led perioperative oral care.

Acinetobacter: An Enemy after Head and Neck Cancer Operations with Microvascular Free Flap Reconstruction?

Background: Patients after head and neck cancer reconstructive surgical procedures are predisposed to have post-operative surgical site infections (SSI) develop. They are very often caused by multi-drug resistant strains, including Acinetobacter baumannii as the most common one. Methods: The aim of the study was to determine important risk factors contributing to SSI of A. baumannii origin. The analysis included 134 head and neck cancer patients after salvage operations with microvascular free flap reconstruction. The A. baumannii was cultured in 27 of all 48 infected patients. Results: The following risk factors were significantly associated with A. baumannii infection: re-hospitalization before reconstructive operation (p = 0.00011), massive blood loss (p = 0.00277), and need of revision surgical procedure (p = 0.00419). Of patients with A. baumannii infection, 48% were hospitalized in a general intensive care unit (ICU) after operation that, together with prolonged intubation, constituted a strong risk factor of that infection (p = 0.01077). Mean time of hospital stay was significantly longer in the A. baumannii group (58 days vs. 35 days; p = 0.02697). Conclusions: Our analysis identified a subset of head and neck cancer patients after salvage operation with microvascular free flap reconstruction who are at high risk of A. baumannii infection developing. Previously hospitalized patients with extensive blood loss and need of surgical revision necessitate increased monitoring for the development of this complication. Mechanical ventilation and hospital stay in an ICU should be shortened maximally or avoided in that challenging group of patients. Early recognition of patients at high risk remains a key point to prevent or limit the spread of A. baumannii infections.

Predicting length of stay in head and neck patients who undergo free flap reconstruction

OBJECTIVE

Understanding factors that affect postoperative length of stay (LOS) may improve patient recovery, hasten postoperative discharge, and minimize institutional costs. This study sought to (a) describe LOS among head and neck patients undergoing free flap reconstruction and (b) identify factors that predict increased LOS.

METHODS

A retrospective cohort was performed of 282 head and neck patients with free flap reconstruction for oncologic resection between 2011 and 2013 at a tertiary academic medical center. Patient demographics, tumor characteristics, and surgical and infectious complications were characterized. Multivariable regression identified predictors of increased LOS.

RESULTS

A total of 282 patients were included. Mean age was 64.7 years (SD = 12.2) and 40% were female. Most tumors were located in the oral cavity (53.9% of patients), and most patients underwent radial forearm free flap (RFFF) reconstruction (RFFF-73.8%, anterolateral thigh flap-11.3%, and fibula free flap-14.9%). Intraoperative complications were rare. The most common postoperative complications included nonwound infection (pneumonia [PNA] or urinary tract infection [UTI]) (15.6%) and wound breakdown/fistula (15.2%). Mean and median LOS were 13 days (SD = 7.7) and 10 days (interquartile range = 7), respectively. Statistically significant predictors of increased LOS included flap take back (Beta coefficient [C] = +4.26, P < .0001), in-hospital PNA or UTI (C = +2.52, P = .037), wound breakdown or fistula (C = +5.0, P < .0001), surgical site infection (C = +3.54, P = .017), and prior radiation therapy (C = +2.59, P = .004).

CONCLUSION

Several perioperative factors are associated with increased LOS. These findings may help with perioperative planning, including the need for vigilant wound care, optimization of antibiotics prophylaxis, and institution-level protocols for postoperative care and disposition of free flap patients.

Development and Validation of Nomograms for Predicting Delayed Postoperative Radiotherapy Initiation in Head and Neck Squamous Cell Carcinoma

Importance

The standard of care for initiation of postoperative radiotherapy (PORT) in head and neck squamous cell carcinoma (HNSCC) is within 6 weeks of surgical treatment. Delays in guideline-adherent PORT initiation are common, associated with mortality, and a measure of quality care, but patient-specific tools to estimate the risk of these delays are lacking.

Objective

To develop and validate 2 nomograms (that use presurgical and postsurgical data) for predicting delayed PORT initiation.

Design, Setting, and Participants

This cohort study obtained patient data from January 1, 2004, to December 31, 2015, from the National Cancer Database. Adults aged 18 years or older with a newly diagnosed HNSCC who underwent surgical treatment and PORT at a Commission on Cancer-accredited facility were included. Data analysis was conducted from June 2, 2019, to January 29, 2020.

Exposures

Surgical treatment and PORT.

Main Outcomes and Measures

The primary outcome measure was PORT initiation more than 6 weeks after the surgical intervention. Multivariable logistic regression models were created in a random selection of 80% of the sample (derivation cohort) and were internally validated with bootstrapping, assessed for discrimination by calibration plots and the concordance (C) index, and externally validated in the remaining 20% of the sample (validation cohort).

Results

The study included 60 766 adults with HNSCC who were grouped into derivation and validation cohorts. The derivation cohort comprised 48 625 patients (mean [SD] age, 59.59 [11.3] years; 36 825 men [75.7%]) selected randomly from the full sample, whereas 12 151 patients (mean [SD] age, 59.63 [11.2] years; 9266 men [76.3%]) composed the validation cohort. The rate of PORT delay was 55.8% (n=27140) in the derivation cohort and 56.7% (n=6900) in the validation cohort. Both nomograms created to predict the risk of PORT initiation delay used variables, including race/ethnicity, insurance type, tumor site, and facility type. The nomogram based on presurgical variables included clinical stage and severity of comorbidity, whereas the nomogram with postsurgical variables included US region, length of stay, and care fragmentation between surgical and radiotherapy facilities. For the presurgical nomogram, the concordance indices were 0.670 (95% CI, 0.664-0.676) in the derivation cohort and 0.674 (95% CI, 0.662-0.685) in the validation cohort. For the nomogram with postsurgical variables, the concordance indices were 0.691 (95% CI, 0.686-0.696) in the derivation cohort and 0.694 (95% CI, 0.685-0.704) in the validation cohort.

Conclusions and Relevance

This study found that a nomogram developed with presurgical data to generate personalized estimates of PORT initiation delay may improve pretreatment counseling and the delivery of interventions to patients at high risk for such a delay. A nomogram including postsurgical data can drive institutional quality improvement initiatives and enhance risk-adjusted comparisons of delay rates across facilities.

National Surgical Quality Improvement Program risk calculator validity in South Australian laryngectomy patients

BACKGROUND

Assessing an individual patient's post-operative risk profile prior to laryngectomy for cancer is difficult. The American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) risk calculator was developed to better inform preoperative decision-making. The calculator uses patient-specific characteristics to estimate the risk of experiencing post-operative complications within 30 days of surgery. We investigated the ACS-NSQIP risk calculator's performance for Australian laryngectomy patients.

METHODS

The ACS-NSQIP risk calculator was used to retrospectively calculate the 30-day post-operative predicted outcomes in patients who underwent laryngectomy for laryngeal, hypopharyngeal and thyroid cancers (with laryngeal involvement) in two institutions in South Australia. These data were compared against the actual mortality, morbidity, complications and length of stay (LOS) collected from a retrospective chart review.

RESULTS

A total of 144 patients underwent surgical intervention for malignancies with laryngeal involvement. The median LOS was 25 days (range 13-197) compared to the predicted LOS of 6.5 days (range 3.5-12.5). Overall mortality was 2.78% with post-operative complications occurring in 63% of patients. The most common complication was wound infection, occurring in 33% of patients. Hosmer-Lemeshow plots demonstrated good agreement between predicted and observed rates for complications.

CONCLUSION

The ACS-NSQIP risk calculator effectively predicted post-operative complication rates in South Australian laryngeal cancer patients undergoing laryngectomy. However, differences in predicted and actual LOS may limit the usefulness of the calculator's LOS predictions for Australian patients.

Airway management techniques in head and neck cancer surgeries: a retrospective analysis

BACKGROUND

The aim of this study was to conduct a retrospective analysis of modalities of airway management and its impact on patients undergoing head and neck cancer surgeries.

MATERIALS AND METHODS

A retrospective review of the medical record of 500 patients operated from January 2008 to December 2013 was conducted at our institute. Patients were reviewed for a mode of airway management, a total length of post-operative hospital stay (PLOS), and incidence of elderly patients in the total number of head and neck cancer surgeries posted for various diagnostic and definitive treatments.

RESULTS

Out of 500 patients, 462 patients (92.4%) underwent nasal intubation, of which 320 underwent fiberoptic (FO) intubation (64%), 7 underwent tracheotomies after completion of surgery (1.4%), and 3 underwent at the beginning of surgery (0.6%). The remaining 38 patients (7.6%) underwent oral intubation.

CONCLUSION

Nasotracheal intubation using fiberoptic bronchoscopy is the most preferred technique for the management of a difficult airway. Efficient airway management during the perioperative period significantly reduces the post-operative length of hospital stay and morbidity.

Quality Indicators: Measurement and Predictors in Head and Neck Cancer Free Flap Patients

Objective

To determine the predictors of length of stay (LOS), readmission within 30 days, and unplanned return to the operating room (OR) within 30 days in head and neck free flap patients.

Study Design

Case series with chart review.

Setting

Tertiary academic cancer hospital.

Subjects and Methods

All head and neck free flap patients at The Ohio State University (OSU, 2006-2012) were assessed. Multivariable logistic regression to assess the impact of patient factors, flap and wound factors, and intraoperative factors on the aforementioned quality metric outcomes.

Results

In total, 515 patients were identified, of whom 66% had oral cavity cancers, 33% had recurrent tumors, and 28% underwent primary radiotherapy. Of the patients, 31.5% had a LOS greater than 9 days, predicted by longer operative time, oral cavity and pharyngeal tumor sites, blood transfusion, diabetes mellitus, and any complication. A total of 12.6% of patients were readmitted within 30 days predicted by absent OSU preoperative assessment clinic attendance and any complication, and 14.8% of patients had an unplanned OR return predicted by advanced age.

Conclusions

When assessing quality metrics, adjustment for the complexity involved in managing patients with head and neck cancer with a high comorbidity index, clean contaminated wounds, and a high degree of primary radiotherapy is important. Patients seen in a preoperative assessment clinic had a lower risk of readmission postoperatively, and this should be recommended for all head and neck free flap patients. Quality improvement projects should focus on predictors and prevention of complications as this was the number one predictor of both increased length of stay and readmission.

Airway management and postoperative length of hospital stay in patients undergoing head and neck cancer surgery

Background and Aims:

General anesthesia and airway management of patients for head and neck cancer surgery is a challenge for the anesthesiologist. Appropriate assessment and planning are essential for successful airway management. Our objectives were to review airway management strategies in patients undergoing head and neck cancer surgery in our tertiary care institution and also to observe the effect of airway management techniques on postoperative length of hospital stay (PLOS).

Material and Methods:

A retrospective medical record review of 400 patients who underwent major head and neck cancer surgery in our institution was conducted. A special form was used, and records were searched for airway and anesthetic management in the operating room and recovery room, and for PLOS.

Results:

289 (72.25%) of the patients were male, and 111 (27.75%) female. 49.8% of patients had Mallampati score of 3 and 4. Airway was managed with tracheostomy in 81 (20.25%) patients; nasal intubation was performed in 177 (44.25%) and oral intubation in 142 (35.5%) patients. Postoperative emergency tracheostomy was not done in any of the patients.

Conclusion:

Median postoperative hospital stay was significantly longer (P = 0.0005) in patients who had a tracheostomy performed compared with those where the airway was managed without it.

Algorithm to predict postoperative complications in oropharyngeal and oral cavity carcinoma

BACKGROUND

Preoperative data in patients with oral cavity/oropharyngeal cancer may predict postoperative complications that may modify therapeutic choices and improve patient care.

METHOD

We reviewed 320 consecutive patients with oral cavity/oropharyngeal cancer, operated on 2003 through 2006 at the European Institute of Oncology. By multivariate analysis of preoperative patient and tumor characteristics, we developed an algorithm to predict postoperative complications. We tested the algorithm on a new series of 307 patients operated on 2007 through 2010.

RESULTS

The final algorithm used to produce a nomogram was comprised of: alcohol consumption (p = .01), site of primary (p = .03), interaction of clinical T classification to sex (p = .007), and type of neck dissection (p < .0001). The algorithm had good ability to predict complications (concordance index [c-index] 0.74) in the new series.

CONCLUSION

The nomogram accurately predicts presurgical risk of postoperative local/systemic complications in patients with oral cavity/oropharyngeal cancer and can be used to adapt therapy to patient characteristics, optimize ward admissions, and improve care.

Impact of a clinical pathway on hospital costs, length of stay and early outcomes after hepatectomy for hepatocellular carcinoma

BACKGROUND

A clinical pathway (CP) can standardize and improve perioperative care for a number of interventions. In hepatic surgery, however, pertinent evidence is very limited. This study was conducted to implement a CP for hepatocellular carcinoma (HCC) patients undergoing hepatectomy, and to evaluate its effects on hospital costs, length of hospital stay (LOHS) and early clinical outcomes.

MATERIALS AND METHODS

Medical records for HCC patients undergoing hepatectomy were retrospectively reviewed before implementation of a CP (the non-CP group) from March 2012 to August 2012. This information was compared with the data collected prospectively from patients after implementation of the CP (the CP group) between September 2012 and April 2013. Hospital costs, LOHS and early clinical outcomes were evaluated and compared between groups.

RESULTS

There were no significant differences in terms of patient clinical characteristics between the two groups. For clinical outcome measures, no significant differences were found in postoperative complications, mortality and readmission rate. The hospital costs were significantly reduced from 24,844 RMB in the non-CP group to 19,761 RMB in the CP group (p<0.01). In addition, patients of the CP group also had shorter LOHS compared with the non-CP group (8.3 versus 12.3 days, p<0.001).

CONCLUSIONS

The CP proved to be an effective approach to minimize hospital costs and LOHS with hepatectomy for HCC without compromising patient care.
