Improving Outpatient Follow-Up Rates for New In-Hospital Consults

This investigation aimed to define the rate of outpatient follow-up after in-hospital consultation, identify factors associated with establishing care, and evaluate an alternative scheduling process to improve outpatient adherence.

Two-phase, prospective study at an academic, tertiary-care institution from March 2020 to August 2022. First, all patients not previously known to our practice encountered via inpatient consult who warranted outpatient follow-up were prospectively captured. Logistic regression analysis was used to identify demographic, disease, and practice factors predictive of follow-up. Second, a randomized control trial was performed to validate the effects of pre-assigning appointments prior to discharge.

Six hundred subjects were included in the final study cohort; 500 in phase-one, and 100 randomized during phase-two. In the phase-one cohort, 54% (n = 272) were lost to follow-up. Multivariate analysis showed increased odds of outpatient follow-up when appointments were pre-assigned before discharge (odds ratio [OR]: 3.69 [95% confidence interval [CI]: 2.29-5.96], p < 0.001), the primary reason for hospitalization was ENT and consult-related (OR: 3.29 [1.92-5.64], p < 0.001), and the diagnosis was one of Oncology (OR: 1.93 [1.02-3.69], p = 0.045) or Pediatrics (OR: 3.36 [1.41-7.98], p = 0.006) subspecialties. During phase-two, subjects randomized for pre-assigned appointments had higher outpatient follow-up (82%) compared to the control group (20%) (p < 0.001).

Hospital-based consultations represent an important referral pathway for new patients. Disease characteristics may identify patients less likely to follow-up upon discharge. Appointment scheduling protocols, including pre-assigning appointments, are modifiable targets for improving adherence to care. Laryngoscope, 133:2540-2545, 2023.
