Analysis of socioeconomic factors in laryngology clinic utilization for treatment of dysphonia

Socioeconomic Determinants of Health and Reflux Management: Insights from a Tertiary Medical Center

OBJECTIVES

To assess the correlation of social determinants of health (SDOH) with the general care patterns related to gastroesophageal reflux disease and laryngopharyngeal reflux. Determine correlation of SDOH on utilization rates for medication, reflux testing and surgical intervention for patients diagnosed with reflux. Describe overall care patterns for gastroesophageal reflux disease care at a tertiary academic facility.

STUDY DESIGN

Retrospective chart review.

METHODS

Patient demographics (age, sex, race, ethnicity, and insurance status) were extracted for adults diagnosed with reflux between 2009 and 2019. Odds ratios (ORs) for the associations between sociodemographic factors and reflux treatment pathways were determined by chi-square analyses.

RESULTS

A total of 143,786 patients were evaluated during the study period with a diagnosis code of reflux. A subgroup of 40,754 patients had objective reflux testing including Bravo, dual pH-impedance, manometry, esophagogastroduodenoscopy (EGD) and esophagram, but no significant difference in utilization rates was found. A total of 239 patients who failed medical management underwent fundoplication. White (OR 2.43, 95% confidence interval [CI] 1.56-3.70) and female (OR 1.37, 95% CI 1.05-1.79) patients were more likely to undergo fundoplication than Black (OR 0.42, 95% CI 0.25-0.70) and male (OR 0.72, 95% CI 0.55-0.95) patients. Patients with private insurance (OR 1.58, 95% CI 1.23-2.04) were more likely to undergo fundoplication than those with public insurance (OR 0.65, 95% CI 0.50-0.84). Male patients were less likely to undergo fundoplication (OR 0.69, 95% CI 0.49-0.98) among patients evaluated for reflux with EGD.

CONCLUSIONS

SDOH correlate with patterns of reflux evaluation and management at our tertiary care center.

Evaluation of Social Determinants of Health on Dysphagia Care Pathways at a Tertiary Care Facility

OBJECTIVES

Limited research exists evaluating the impact of social determinants of health in influencing care pathways for patients with dysphagia. A better understanding of whether these determinants correlate to altered care and resource utilization is essential as it relates to patient outcomes.

STUDY DESIGN

Retrospective chart review.

METHODS

All adult patients seen at a tertiary midwestern hospital were screened for ICD codes of dysphagia diagnoses from 2009 to 2019. Demographic information was collected from these patients with dysphagia including sex, race, ethnicity, and insurance status. Subgroup analysis was performed to assess referral pattern rates and types of diagnostic interventions ordered (none, videofluoroscopic swallow study, esophagram, and esophagogastroduodenoscopy).

RESULTS

A total of 31,858 patients with dysphagia were seen at our institution during the study period, with a majority being female (56.36%), Caucasian (79.83%), and publicly insured (63.16%), at a median age of 60.35 years. There were no significant care delivery pattern differences based on geography/zip code analyses. African American patients were significantly more likely to have imaging or interventions performed (odds ratio [OR] 1.463, p = 0.005). Patients with public insurance also had higher rates of diagnostic study utilization (OR 1.53, p = 0.01). Only 3% of all patients with dysphagia were seen by laryngologists.

CONCLUSION

No significant differences were seen in dysphagia evaluation modalities based on zip code analyses surrounding this tertiary care facility. African American patients and those with public insurance had significantly higher utilization of subsequent testing and intervention for dysphagia care. Further studies are necessary to delineate causes and outcome differences for these measurable differences in dysphagia care pathways.

Association of Sociodemographic Factors on the Presentation and Management of Unilateral Vocal Fold Immobility

OBJECTIVE

To determine the association of social determinants of health (SDOH) on the presentation and management of unilateral vocal fold immobility (UVFI).

METHODS

Retrospective chart review of 207 adult UVFI patients evaluated at a tertiary-care hospital between 2018 and 2019 was performed. Sociodemographic factors including gender, median household income, preferred language, and insurance type were recorded. Confounding clinical factors including etiology of UVFI, Voice Handicap Index-10 (VHI-10) score, laryngoscopic findings, and intervention history were extracted from medical records. Multivariable logistic regression was performed using sociodemographic and clinical factors.

RESULTS

Patient demographics and socioeconomic status were not associated with time to presentation. Patients presenting with glottic insufficiency and UVFI due to malignancy or recurrent laryngeal nerve (RLN) sacrifice had a shorter time to presentation. Higher household income was associated with greater number of interventions (p = 0.02), but neither income nor insurance type affected intervention type or timing. Female patients were less likely to undergo injection medialization laryngoplasty (odds ratio [OR] 0.25, p = 0.005). Older patients were more likely to undergo injection (OR 1.04, p = 0.027). Patients with large glottic gaps (OR 21.2, p = 0.014) and higher VHI-10 scores (OR 1.06, p = 0.047) were more likely to undergo surgery.

CONCLUSION

Higher household income was associated with greater number of interventions and longer duration of care at a private tertiary-care hospital. RLN sacrifice, known malignancy, and glottic insufficiency significantly reduced the time to presentation. Type of intervention received was a complex interplay of both demographic and clinical factors. Large prospective studies should examine the role of SDOH in the presentation and management of UVFI.

Demographic differences in the treatment of unilateral vocal fold paralysis

Objective

To determine the impact of patient demographics and social determinants of health on treatment pathways for unilateral vocal fold paralysis (UVFP) at a tertiary laryngology clinic.

Study design

Retrospective medical record review.

Methods

Patient demographics (age, gender, race, ethnicity, and insurance status) were extracted for adults diagnosed with UVFP between 2009 and 2019. Odds ratios for the associations between sociodemographic factors and UVFP treatment pathways were determined by chi-square analyses.

Results

A total of 1490 UVFP diagnoses were identified during the study period with the majority being female (58%), White (85%), non-Hispanic (97%), and publicly insured (54%). Five treatment pathways were identified: observation, injection laryngoplasty, voice therapy, laryngeal framework surgery/thyroplasty, and reinnervation surgery. There were 538 patients who underwent observation, 512 injection laryngoplasty, 366 voice therapy, 136 thyroplasty, and 26 laryngeal reinnervation surgery. Males were more likely to undergo injection laryngoplasty than females (OR 1.32; CI 1.08-1.61), whereas females were more likely to undergo voice therapy (OR 1.39; CI 1.09-1.76). Patients with public insurance (OR 1.48; CI 1.03-2.14) and Hispanics (OR 2.60; CI 1.18-5.72) were more likely to undergo thyroplasty. Patients who underwent reinnervation surgery were younger than those in other treatment pathways (median: 39.1 years vs. 50.7-56.1 years).

Conclusions

Gender, ethnicity, and insurance status were significantly associated with specific UVFP treatment pathways. Patients with public insurance were more likely to undergo surgical intervention than voice therapy. This data overall supports differences in care pathway utilization for UVFP based on social determinants of health.
