Discharge Disposition After Head and Neck Reconstruction: Effect on Adjuvant Therapy and Outcomes

OBJECTIVES

Head and neck cancer patients that require major reconstruction often have advanced-stage disease. Discharge disposition of patients can vary and impact time to adjuvant treatment. We sought to examine outcomes in patients discharged to skilled nursing facilities (SNF) compared to those discharged home, including the impact on adjuvant therapy initiation and treatment package time (TPT).

METHODS

Patients with head and neck squamous cell carcinoma treated with surgical resection and microvascular free flap reconstruction from 2019 to 2022 were included. Retrospective review was conducted to evaluate the impact of disposition on time to radiation (RT) and TPT.

RESULTS

230 patients were included, with 165 (71.7%) discharged to home and 65 (28.3%) discharged to SNF. 79.1% of patients were recommended adjuvant therapy. Average time to RT was 59 days for patients discharged to home compared to 70.1 days for patients discharged to SNF. Disposition was an independent risk factor for delays to starting RT (p = 0.03). TPT was 101.7 days for patients discharged to home versus 112.3 days for those who discharged to SNF. Patients discharged to SNF had higher rates of readmission (p < 0.005) compared to patients discharged home in an adjusted multivariate logistic regression.

CONCLUSIONS

Patients discharged to an SNF had significantly delayed time to initiation of adjuvant treatment and higher rates of readmission. Timeliness to adjuvant treatment has recently been established as a quality measure, thus identifying delays to adjuvant treatment initiation should be a priority.

Institutional financial toxicity of failure to adhere to treatment guidelines for head and neck squamous cell carcinoma

BACKGROUND

Delays in treatment of head and neck squamous cell carcinoma (HNSCC) are known to increase disease recurrence, generating the need for additional salvage treatment, often with immunotherapy.

METHODS

Three treatment metrics were identified: time from diagnosis to treatment initiation (TTI), time from surgery to postoperative radiotherapy (surg → PORT), and total treatment package time (TPT). Financial toxicity was calculated using hazard ratios, pembrolizumab cost, and dosing data for a Veterans Health Administration (VHA) institutional cohort (n = 338) and a standardized cohort (n = 100).

RESULTS

Estimated financial toxicity for the VHA cohort was $2 047 407, $316 545, and $1 114 101 for TTI, surg → PORT, and TPT, respectively. Estimated financial toxicity for the standardized patient cohort was $454 028, $544 576, and $1 879 628 for TTI, surg → PORT, and TPT, respectively.

CONCLUSIONS

Failure to meet established HNSCC treatment metrics generates significant, yet avoidable, institutional financial toxicity which is particularly relevant to integrated single-payer systems such as the VHA in the modern immunotherapy era.

Quantitative survival impact of composite treatment delays in head and neck cancer

BACKGROUND

Multidisciplinary management of head and neck cancer (HNC) must reconcile increasingly sophisticated subspecialty care with timeliness of care. Prior studies examined the individual effects of delays in diagnosis-to-treatment interval, postoperative interval, and radiation interval but did not consider them collectively. The objective of the current study was to investigate the combined impact of these interwoven intervals on patients with HNC.

METHODS

Patients with HNC who underwent curative-intent surgery with radiation were identified in the National Cancer Database between 2004 and 2013. Multivariable models were constructed using restricted cubic splines to determine nonlinear relations with overall survival.

RESULTS

Overall, 15,064 patients were evaluated. After adjustment for covariates, only prolonged postoperative interval (P < .001) and radiation interval (P < .001) independently predicted for worse outcomes, whereas the association of diagnosis-to-treatment interval with survival disappeared. By using multivariable restricted cubic spline functions, increasing postoperative interval did not affect mortality until 40 days after surgery, and each day of delay beyond this increased the risk of mortality until 70 days after surgery (hazard ratio, 1.14; 95% confidence interval, 1.01-1.28; P = .029). For radiation interval, mortality escalated continuously with each additional day of delay, plateauing at 55 days (hazard ratio, 1.25; 95% confidence interval, 1.11-1.41; P < .001). Delays beyond these change points were not associated with further survival decrements.

CONCLUSIONS

Increasing delays in postoperative and radiation intervals are associated independently with an escalating risk of mortality that plateaus beyond certain thresholds. Delays in initiating therapy, conversely, are eclipsed in importance when appraised in conjunction with the entire treatment course. Such findings may redirect focus to streamlining those intervals that are most sensitive to delays when considering survival burden. Cancer 2018. © 2018 American Cancer Society.
