RESUMO

BACKGROUND: Cancer centers are regionalizing care to expand patient access, but the effects on patient volume are unknown. This study aimed to compare patient volumes before and after the establishment of head and neck regional care centers (HNRCCs). METHODS: This study analyzed 35,394 unique new patient visits at MD Anderson Cancer Center (MDACC) before and after the creation of HNRCCs. Univariate regression estimated the rate of increase in new patient appointments. Geospatial analysis evaluated patient origin and distribution. RESULTS: The mean new patients per year in 2006-2011 versus 2012-2017 was 2735 ± 156 patients versus 3155 ± 207 patients, including 464 ± 78 patients at HNRCCs, reflecting a 38.4 % increase in overall patient volumes. The rate of increase in new patient appointments did not differ significantly before and after HNRCCs (121.9 vs 95.8 patients/year; P = 0.519). The patients from counties near HNRCCs, showed a 210.8 % increase in appointments overall, 33.8 % of which were at an HNRCC. At the main campus exclusively, the shift in regional patients to HNRCCs coincided with a lower rate of increase in patients from the MDACC service area (33.7 vs. 11.0 patients/year; P = 0.035), but the trend was toward a greater increase in out-of-state patients (25.7 vs. 40.3 patients/year; P = 0.299). CONCLUSIONS: The creation of HNRCCs coincided with stable increases in new patient volume, and a sizeable minority of patients sought care at regional centers. Regional patients shifted to the HNRCCs, and out-of-state patient volume increased at the main campus, optimizing access for both local and out-of-state patients.

RESUMO

BACKGROUND: The objective of this study was to compare the cosmesis and recurrence rates of conventional excision (CE), Mohs micrographic surgery (MMS), external-beam radiation therapy (EBRT), or brachytherapy (BT), for basal cell carcinoma and squamous cell carcinoma of the skin. METHODS: Population, Intervention, Control, Outcome, Study Design (PICOS), Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), and Meta-Analyses of Observational Studies in Epidemiology (MOOSE) methods were used to identify studies on PubMed (from 1985 to 2018), including patients with American Joint Committee on Cancer (AJCC) T1-T2N0 basal cell carcinomas and squamous cell carcinomas and ≥10 months follow-up who received CE, MMS, EBRT, or BT. The primary endpoint was cosmesis, classified as "good," "fair," or "poor." The secondary endpoint was 1-year recurrence. Fixed-effects and random-effects meta-analyses were performed to evaluate primary and secondary outcomes with respect to treatment modality. RESULTS: In total, 18,095 studies met initial search criteria. There were 24 CE, 13 MMS, 19 EBRT, and 7 BT studies included with a total of 21,371 patients. The summary effect size for "good" cosmesis was 81% (95% CI, 70.6%-89.6%), 74.6% (95% CI, 63%-84.6%), and 97.6% (95% CI, 91.3%-100%) for CE, EBRT, and BT, respectively. Good cosmesis was 96.0% in the only MMS study that reported cosmesis. BT had improved "good" cosmesis over EBRT (P = .0025) and was similar to CE and MMS. No significant differences were seen for "fair" or "poor" cosmesis. One-year recurrence rates were low throughout at 0.8% (95% CI, 0.3%-1.6%), 0.2% (95% CI, 0%-0.6%), 2% (95% CI, 1.3%-2.7%), and 0% (95% CI, 0%-0.5%) for CE, MMS, EBRT, and BT, respectively. CONCLUSIONS: For T1-T2N0 skin cancers, BT and MMS have improved cosmesis over EBRT and CE. It is unclear whether this is because of treatment superiority or selection and reporting bias. Local control is similar among all modalities at 1 year.

RESUMO

BACKGROUND: The association between regional breast cancer diagnostic rates, treatments, and outcomes is unclear. We sought to investigate the management and survival of women with invasive ductal carcinoma (IDC) from geographic regions with variable rates of diagnosis. METHODS: Data on women diagnosed with IDC years 2009-2010 were obtained from the Surveillance, Epidemiology, and End Results database. Patients were divided into quartiles based on the IDC diagnostic rate within their county of residence. Chi-square and one-way analysis of variance (ANOVA) analyses tested the association between patient and clinical characteristics and the diagnostic rate quartiles. Cox regression analyses compared survival between the quartiles. RESULTS: Among the 83,375 patients included, the mean age was 60.8 y and 70.9% were white. Patients residing in counties with the highest diagnostic rates were more frequently white, employed, educated, and wealthier and more often received adjuvant radiation following both partial mastectomy for localized disease and complete mastectomy for advanced disease compared to patients in counties with the lowest diagnostic rates. The highest diagnostic rate quartile had 10% decreased odds of death compared to the lower quartile (hazard ratio: 0.897; 95% confidence interval: 0.832-0.966). However, after adjustment for socioeconomic variables, survival was comparable (hazard ratio: 0.916; 95% confidence interval: 0.835-1.003). CONCLUSIONS: Regional variation in IDC diagnostic rates is associated with differences in socioeconomic status, grade, stage, and treatment. Patients from regions with the highest rates of diagnosis may have improved access to evidence-based care and resultant superior survival. Enhancing access to care may improve outcomes of patients residing in regions where breast cancer is diagnosed less frequently.

RESUMO

Vocal cord paralysis after administration of the chemotherapeutic agent vincristine is a rare occurrence. Most occurrences are bilateral. Of the 24 cases referenced in this article, 19 are children. In all the reported cases, symptoms have occurred after multiple doses of vincristine have been administered. The authors report a case of a 39-year-old woman with unilateral vocal cord motion impairment occurring 3 days after the administration of the first dose of vincristine. This is the first case of vocal cord motion impairment reported after the administration of only 1 dose of this drug.

RESUMO

The free fibula flap is the preferred reconstructive method for oncologic defects of the mandible. Arterial inflow of the extremity is routinely evaluated with several modalities; however, venous screening is rarely performed. Patients with cancer are at elevated risk of occult deep venous thrombosis (DVT). An asymptomatic thrombus encountered during free fibula reconstruction is a serious concern. Although such cases have been reported, we suspect the incidence of DVT during fibula free flap harvest is underappreciated. This monograph uses a case example to review risk factors for occult DVT, present a strategy for preoperative assessment, and provide a reconstructive algorithm to for mandibular reconstruction in such instances.

RESUMO

BACKGROUND: In head and neck cancer patients prior to treatment, dysphagia noted by patients is more common than aspiration on formal swallow studies. The authors hypothesized that patient-reported dysphagia impacts multiple domains of quality of life (QOL) and predicts disease recurrence and disease-related death. METHODS: The Swal-QOL, a dysphagia-specific, swallowing-related, QOL measure, and the EuroQOL-5D-3L were administered to 159 patients before treatment with curative intent in this prospective cohort study. Logistic regression analysis evaluated associations among clinical and subjective measures. Multivariable competing risk regression tested the impact of clinical, tumor, and patient-reported measures on survival. RESULTS: Baseline dysphagia, pain, and diminished patient-reported health state were found to be closely associated with weight loss before treatment and advanced T classification. However, only 58% of patients (23 of 40 patients) reporting dysphagia experienced > 5% weight loss. Dysphagia was found to be associated with pain and/or diminished patient-reported health state, independent of weight loss. Female patients were more likely to report pain and dysphagia, whereas male patients reported dysphagia alone. Dysphagia was found to be predictive of disease recurrence and disease-related death, adjusting for T and N classifications, ECOG performance status, smoking status, and weight loss, and accounting for competing risks of death (recurrence-free survival: hazards ratio, 3.8 [95% confidence interval, 1.7-8.4; P = .001] and disease-related death: hazards ratio, 4.2 [95% confidence interval, 1.04-5; P = .004]). CONCLUSIONS: Baseline dysphagia affects multiple domains of QOL and general health perceptions in patients with head and neck cancer prior to treatment. A dysphagia measure captures the effort of maintaining nutrition, and identifies patients predisposed to disease recurrence and disease-related death.

RESUMO

OBJECTIVE: Patients treated for oropharyngeal cancer (OPC) have historically demonstrated high feeding tube rates for decreased oral intake and malnutrition. We re-examined feeding tube practices in these patients. STUDY DESIGN: Retrospective analysis of prospective cohort from 2015 to 2021. SETTING: Single-institution NCI-Designated Comprehensive Cancer Center. METHODS: With IRB approval, patients with new oropharyngeal squamous cell cancer or (unknown primary with neck metastasis) were enrolled. Baseline swallowing was assessed via videofluoroscopy and Performance Status Scale for Head and Neck Cancer (PSSHN). G-tubes or nasogastric tubes (NGT) were placed for weight loss before, during, or after treatment. Prophylactic NGT were placed during transoral robotic surgery (TORS). Tube duration was censored at last disease-free follow-up. Multivariate regression was performed for G-tube placement (odds ratio [OR] [95% confidence interval [CI]) and removal (Cox hazard ratio, hazard ratio [HR] [95% CI]). RESULTS: Of 924 patients, most had stage I to II (81%), p16+ (89%), node-positive (88%) disease. Median follow-up was 2.6 years (interquartile range 1.5-3.9). Most (91%) received radiation/chemoradiation, and 16% received TORS. G-tube rate was 27% (5% after TORS). G-tube risk was increased with chemoradiation (OR 2.78 [1.87-4.22]) and decreased with TORS (OR 0.31 [0.15-0.57]) and PSSHN-Diet score ≥60 (OR 0.26 [0.15-0.45]). G-tube removal probability over time was lower for T3 to T4 tumors (HR 0.52 [0.38-0.71]) and higher for PSSHN-Diet score ≥60 (HR 1.65 [1.03-2.66]). CONCLUSIONS: In this modern cohort of patients treated for OPC, 27% received G-tubes-50% less than institutional rates 10 years ago. Patients with preserved baseline swallowing and/or those eligible for TORS may have lower G-tube risk and duration.

RESUMO

We report the case of a 77-year-old non-smoker and non-drinker with a solid-organ transplant who had malignant transformation of respiratory papillomatosis 3 years after the initial diagnosis of this benign lesion. This is the first case reported in the literature of malignant transformation of respiratory papillomatosis in a solid-organ transplant patient. Virus-associated cutaneous cancers occur more frequently and aggressively in solid-organ transplant patients. There may be a higher rate of malignant transformation of respiratory papillomatosis in immunosuppressed patients, as this is a virus-associated disease. Closer observation, airway evaluation with laryngoscopy and tracheobronchoscopy, and interval biopsies of immunosuppressed patients with respiratory papillomatosis is recommended.

RESUMO

Importance: Counseling prior to thyroid cancer (TC) treatment is an essential component of informed consent. An informed patient affects treatment-related expectations and patient engagement, factors that contribute significantly to patient-reported quality-of-life outcomes. Objective: To describe experiences with pretreatment counseling among survivors of TC and to test factors associated with self-reported treatment meeting expectations. Design, Setting, and Participants: A cross-sectional survey was administered between October 18, 2019, and February 8, 2020, to members of ThyCa: Thyroid Cancer Survivors' Association Inc, and to individuals accessing the public-facing ThyCa website. Survey respondents were asked 55 questions, including 4 free-text questions and 2 multiple-choice questions about pretreatment counseling. Main Outcomes and Measures: Respondents self-reported (1) their unmet information needs, (2) rates of treatment meeting expectations, and (3) rates of treatment understanding. A mixed-methods analysis was performed, including qualitative content analysis of free-text responses and multivariable logistic regression of factors associated with self-reported levels of treatment meeting expectations. Results: Of the 1412 survey respondents, 1249 were women (88.4%). The median age at diagnosis was 48 years (range, 18-85 years), and the median age at the time of survey completion was 60 years (range, 18-87 years). A total of 1259 respondents (89.2%) provided free-text responses to the question, "What would you tell someone newly diagnosed with your same condition?" Of these individuals, 526 (37.2%) reported inadequate pretreatment plan understanding and 578 (40.9%) reported that their treatment experience did not meet their expectations. Treatment met expectations for only 95 respondents (18.1%) reporting an inadequate pretreatment plan understanding. Of the 526 survivors of TC reporting a lack of understanding, 473 (90.0%) provided additional textual comments, most commonly in the categories of postoperative treatment, surveillance, and treatment effects. On multivariable logistic regression, self-reported failure to have an understanding of TC treatment was independently associated with failure of treatment to meet expectations (odds ratio, 5.1 [95% CI, 3.7-6.9]). Patients reporting a full understanding of their treatment plan were 5-fold more likely to indicate that their initial treatment experience was on par with expectations, independent of reported postoperative complications, age, sex, and other potential confounders. Conclusions and Relevance: In this survey study, a substantial proportion of survivors of TC reported inadequate pretreatment understanding. This gap in understanding was associated with high levels of self-reported failure of treatment to meet expectations, which in turn is associated in other studies with poorer patient-reported quality-of-life outcomes. These outcomes may be improved by addressing gaps in patient understanding so expectations more closely match TC diagnosis and treatment pathways.

RESUMO

The utilization of sentinel lymph node (SLN) biopsy has transformed the workup and staging of intermediate-thickness cutaneous melanomas. SLN biopsy, performed at the time of primary tumor excision, accurately maps lymph nodes at risk of harboring occult metastatic deposits from head and neck cutaneous melanomas and represents the current standard of care. Completion lymphadenectomy identifies additional tumor in 12% to 24% of SLN biopsy positive cases but does not affect melanoma-specific survival.

RESUMO

PURPOSE: Definitive or postoperative chemoradiation (CRT) is curative for human papillomavirus-associated (HPV+) oropharynx cancer (OPC) but induces significant toxicity. As a deintensification strategy, we studied primary transoral surgery (TOS) and reduced postoperative radiation therapy (RT) in intermediate-risk HPV+ OPC. METHODS: E3311 is a phase II randomized trial of reduced- or standard-dose postoperative RT for resected stage III-IVa (American Joint Committee on Cancer-seventh edition) HPV+ OPC, determined by pathologic parameters. Primary goals were feasibility of prospective multi-institutional study of TOS for HPV+ OPC, and oncologic efficacy (2-year progression-free survival) of TOS and adjuvant therapy in intermediate-risk patients after resection. TOS plus 50 Gy was considered promising if the lower limit of the exact 90% binomial confidence intervals exceeded 85%. Quality of life and swallowing were measured by functional assessment of cancer therapy-head and neck and MD Anderson Dysphagia Index. RESULTS: Credentialed surgeons performed TOS for 495 patients. Eligible and treated patients were assigned as follows: arm A (low risk, n = 38) enrolled 11%, intermediate risk arms B (50 Gy, n = 100) or C (60 Gy, n = 108) randomly allocated 58%, and arm D (high risk, n = 113) enrolled 31%. With a median 35.2-month follow-up for 359 evaluable (eligible and treated) patients, 2-year progression-free survival Kaplan-Meier estimate is 96.9% (90% CI, 91.9 to 100) for arm A (observation), 94.9% (90% CI, 91.3 to 98.6]) for arm B (50 Gy), 96.0% (90% CI, 92.8 to 99.3) for arm C (60 Gy), and 90.7% (90% CI, 86.2 to 95.4) for arm D (66 Gy plus weekly cisplatin). Treatment arm distribution and oncologic outcome for ineligible or step 2 untreated patients (n = 136) mirrored the 359 evaluable patients. Exploratory comparison of functional assessment of cancer therapy-head and neck total scores between arms B and C is presented. CONCLUSION: Primary TOS and reduced postoperative RT result in outstanding oncologic outcome and favorable functional outcomes in intermediate-risk HPV+ OPC.

RESUMO

The incidence of Merkel cell carcinoma (MCC) continues to increase. Understanding of MCC biology has advanced rapidly, with current staging providing valuable prognostic information. MCC treatment often is multidisciplinary. Surgery remains an important component in the staging and treatment, most commonly involving wide excision of the cancer and sentinel lymph node biopsy. Lymphadenectomy is used to treat nodal disease. Radiotherapy enhances locoregional control and possibly survival. Systemic therapies, in particular novel immunotherapies, may be promising in the treatment of advanced or recurrent and metastatic disease.

RESUMO

OBJECTIVE: Prognostic factors and optimal treatment approaches for Merkel cell carcinoma (MCC) remain uncertain. This study evaluated the influences of sentinel lymph node (SLN) biopsy and lymphovascular invasion (LVI) on treatment planning and prognosis. STUDY DESIGN: Retrospective cohort study. METHODS: Stage 1 to 3 MCC patients treated 2005 to 2018. Predictors of nodal radiation were tested using logistic regression. Predictors of recurrence-free, disease-specific, and overall survival were tested in Cox proportional hazard models. RESULTS: Of 122 patients, 99 were without clinically apparent nodal metastases. Of these, 76 (77%) underwent excision and SLN biopsy; 29% had metastasis in SLNs, including 20% of MCCs 1 cm or less. Primary tumor diameter, site, patient age, gender, and immunosuppressed status were not significantly associated with an involved SLN. Among patients who underwent SLN biopsy, 13 of 21 (62%) MCCs with LVI had cancer in SLNs compared with 14 of 44 (25.5%) without LVI (P = .003). Although local radiation was common, nodal radiation was infrequently employed in SLN negative (pathologic N0) patients (21.8% vs. 76.2% for patients with SLN metastases, P = .0001). Survival of patients with positive SLNs was unfavorable, regardless of completion lymphadenectomy and/or adjuvant radiation. After accounting for tumor (T) and node (N) classification, age, immunosuppression, and primary site, a positive SLN and LVI were independently associated with worse survival (LVI/recurrence-free survival [RFS]: hazard ratio [HR] 2.3 (1.04-5, P = .04; LVI/disease-specific survival [DSS]: HR 5.2 (1.8-15, P = .007); N1a vs. pN0/RFS HR 3.6 (1.42-9.3, P = .007); DSS HR5.0 (1.3-19, P = .17). CONCLUSION: SLN biopsy assists in risk stratification and radiation treatment planning in MCC. LVI and disease in SLNs, independently associated with worse survival, constitute markers of high-risk disease warranting consideration for investigational studies.

RESUMO

INTRODUCTION: Survivin is an inhibitor of apoptosis that is proposed as a target for anti-cancer therapy because of its high expression in cancer cells. It has potential as a prognostic and predictive biomarker of response to radiation and systemic therapies. We report its expression in head and neck squamous cell carcinoma (HNSCC) and its correlation with treatment response and survival. METHODS: We measured survivin protein expression in tumor specimens from 96 patients with HNSCC treated at Fox Chase Cancer Center, of whom 21 were p16+. Quantitative automated immunofluorescence was employed to score nuclear and cytoplasmic survivin in 5 tissue microarrays (TMAs) consisting of 316 H&N tumor cores and 107 control tissue cores. Survivin levels were then correlated to therapy response and survival outcomes. RESULTS: Using the median score as the cutoff, overall survival (OS) was significantly shorter for the group expressing higher survivin in nuclear (p = 0.013), cytoplasmic (p = 0.018) and total compartments (p = 0.006). No correlation was seen between survivin expression and patient sex or grade of tumor, T or N stage, or p16 status. Survivin expression in metastases did not significantly differ from that in primary tumors. Levels of p53 expression showed a significant positive correlation with higher survivin expression in the cytoplasm (p = 0.0264) and total compartments (p = 0.0264), but not in the nucleus (p = 0.0729). CONCLUSIONS: Survivin expression above the median is associated with shorter overall survival in HNSCC, including for patients treated with chemotherapy or radiation. p16 expression did not correlate with survivin levels.

RESUMO

BACKGROUND: Rapid recurrence, defined as gross tumor recurrence after primary operation but prior to initiating postoperative radiation therapy (PORT), is underappreciated in head and neck cancer (HNC). METHODS: CT simulation images in patients with HNC managed surgically with adjuvant therapy at a single center between 2010 and 2017 were retrospectively reviewed. RESULTS: A total of 194 patients with HNC were included. Rapid recurrence occurred in 39 patients (20%) with a median time from operation to CT simulation of 37 days. On multivariable analysis (MVA), extranodal extension (ENE) was the only predictor of rapid recurrence (P = .03). While rapid recurrence, ENE, and perineural invasion were all associated with poor overall survival (OS) on MVA, rapid recurrence was the strongest predictor (hazard ratio [HR] 5.47). CONCLUSION: Rapid recurrence occurs at an underappreciated rate and is associated with poor survival outcomes. Patients with ENE are at highest risk and may benefit from diagnostic imaging evaluations immediately prior to PORT.

RESUMO

OBJECTIVES: To develop nomograms predicting overall survival (OS), freedom from locoregional recurrence (FFLR), and freedom from distant metastasis (FFDM) for patients receiving chemoradiation for laryngeal squamous cell carcinoma (LSCC). MATERIAL AND METHODS: Clinical and treatment data for patients with LSCC enrolled on NRG Oncology/RTOG 0129 and 0522 were extracted from the RTOG database. The dataset was partitioned into 70% training and 30% independent validation datasets. Significant predictors of OS, FFLR, and FFDM were obtained using univariate analysis on the training dataset. Nomograms were built using multivariate analysis with four a priori variables (age, gender, T-stage, and N-stage) and significant predictors from the univariate analyses. These nomograms were internally and externally validated using c-statistics (c) on the training and validation datasets, respectively. RESULTS: The OS nomogram included age, gender, T stage, N stage, and number of cisplatin cycles. The FFLR nomogram included age, gender, T-stage, N-stage, and time-equivalent biologically effective dose. The FFDM nomogram included age, gender, N-stage, and number of cisplatin cycles. Internal validation of the OS nomogram, FFLR nomogram, and FFDM nomogram yielded c = 0.66, c = 0.66 and c = 0.73, respectively. External validation of these nomograms yielded c = 0.59, c = 0.70, and c = 0.73, respectively. Using nomogram score cutoffs, three risk groups were separated for each outcome. CONCLUSIONS: We have developed and validated easy-to-use nomograms for LSCC outcomes using prospective cooperative group trial data.

RESUMO

The COVID-19 epidemic was not the first coronavirus epidemic of this century and represents one of the increasing number of zoonoses from wildlife to impact global health. SARS CoV-2, the virus causing the COVID-19 epidemic is distinct from, but closely resembles SARS CoV-1, which was responsible for the severe acute respiratory syndrome (SARS) outbreak in 2002. SARS CoV-1 and 2 share almost 80% of genetic sequences and use the same host cell receptor to initiate viral infection. However, SARS predominantly affected individuals in close contact with infected animals and health care workers. In contrast, CoV-2 exhibits robust person to person spread, most likely by means of asymptomatic carriers, which has resulted in greater spread of disease, overall morbidity and mortality, despite its lesser virulence. We review recent coronavirus-related epidemics and distinguish clinical and molecular features of CoV-2, the causative agent for COVID-19, and review the current status of vaccine trials.

RESUMO

OBJECTIVE: To survey a large cohort of thyroid cancer survivors from ThyCa on information needs and expectations of their treatment to better understand the pretreatment counseling, information, and support needs of this population. METHODS: Anonymous survey of thyroid cancer survivors. RESULTS: One thousand one hundred twenty-four patients with thyroid cancer participated in the survey. Three hundred sixty-two (37.44%) reported not having had a full understanding of their treatment plan and 407 (46.41%) reported that their thyroid cancer treatment did not conform to expectations. Patients diagnosed at younger ages were significantly more likely to report inadequate understanding of the treatment, failure of treatment to meet expectations, and call for greater attention to psychological well-being. Older patients were more likely to report unexpected effects on speech and swallowing. Regardless of age, patients most frequently called for greater attention to management of energy levels (endorsed by 61% of respondents), psychological well-being (50%), and weight changes (48%). CONCLUSIONS: Improvements are needed in age-specific communication of thyroid cancer diagnosis and treatment.

RESUMO

OBJECTIVE: Hospital-acquired aspiration pneumonia remains a rare but potentially devastating problem. The best means by which to prevent aspiration in a cancer hospital population has not been evaluated. The aim of this study was to evaluate the impact of dysphagia screening on aspiration pneumonia rates in an acute care oncology hospital. METHODS: A prospective single-institution quality improvement dysphagia screening protocol at a comprehensive cancer center. Effect of dysphagia screening implemented in 2016 on hospital-acquired aspiration pneumonia rates coded "aspiration pneumonitis due to food/vomitus" was compared with rates from 2014 to 2015 prior to implementation. Screening compliance, screening outcomes, patient demographics, and medical data were reviewed as part of a post hoc analysis. RESULTS: Of 12,392 admissions in 2014 to 2016, 97 patients developed aspiration pneumonia during their hospitalization. No significant change in aspiration pneumonia rate was seen during the dysphagia screening year when compared to prior years (baseline, 7.36; screening year, 8.78 per 1000 discharges; P = .33). Sixty-eight of the cases (66%) were associated with emesis/gastrointestinal obstruction or perioperative aspiration and only 15 (15%) with oropharyngeal dysphagia. Multivariate analysis found that patients admitted to gastrointestinal surgery had an aspiration risk equivalent to patients admitted to head and neck, thoracic, and pulmonary services (odds ratio, 0.65; P = .2). DISCUSSION: Nursing-initiated dysphagia screening did not decrease aspiration pneumonia rates. The causes of aspiration-associated pneumonia were heterogeneous. Aspiration of intestinal contents is a more common source of hospital-acquired pneumonia than oropharyngeal dysphagia.
