Cost and safety of inpatient versus outpatient open reduction internal fixation of isolated ankle fractures.

BACKGROUND: As health care shifts to value-based models, one strategy within orthopedics has been to transition appropriate cases to outpatient or ambulatory settings to reduce costs; however, there are limited data on the efficacy and safety of this practice for isolated ankle fractures. The purpose of this study was to compare the cost and safety associated with inpatient versus outpatient ankle open reduction internal fixation (ORIF). METHODS: All patients who underwent ORIF of isolated closed ankle fractures at 2 affiliated hospitals between April 2016 and March 2017 were identified retrospectively. Demographic characteristics, including age, gender, comorbidities and injuryspecific variables, were collected. We grouped patients based on whether they underwent ankle ORIF as an inpatient or outpatient. We determined case costing for all patients and analyzed it using multivariate regression analysis. RESULTS: A total of 196 patients (125 inpatient, 71 outpatient) were included for analysis. Inpatients had a significantly longer mean length of stay than outpatients (54.3 h [standard deviation (SD) 36.3 h] v. 7.5 h [SD 1.7 h], p < 0.001). The average cost was significantly higher for the inpatient cohort than the outpatient cohort ($4137 [SD $2285] v. $1834 [SD $421], p < 0.001). There were more unimalleolar ankle fractures in the outpatient group than in the inpatient group (42 [59.2%] v. 41 [32.8%], p < 0.001). Outpatients waited longer for surgery than inpatients (9.6 d [SD 5.6 d] v. 2.0 d [SD 3.3 d], p < 0.001). Fourteen patients (11.2%) in the inpatient group presented to the emergency department or were readmitted to hospital within 30 days of discharge, compared to 5 (7.0%) in the outpatient group (p = 0.3). CONCLUSION: In the treatment of isolated closed ankle fractures, outpatient surgery was associated with a significant reduction in length of hospital stay and overall case cost compared to inpatient surgery, with no significant difference in readmission or reoperation rates. In medically appropriate patients, isolated ankle ORIF can be performed safely in an ambulatory setting and is associated with significant cost savings.

Wait times, resource use and health-related quality of life across the continuum of care for patients referred for total knee replacement surgery.

Background: The escalating socioeconomic burden of knee osteoarthritis (OA) underscores the need for innovative strategies to reduce wait times for total knee arthroplasty (TKA). The purpose of this study was to evaluate resource use, costs and health-related quality of life (HRQoL) across the continuum of care for patients with knee OA. Methods: This was a prospective study of 383 patients recruited from a high-volume teaching hospital at different stages of care (referral, consultation and presurgery). Outcomes included health care resource use; costs captured from the health care payer, private sector and societal perspectives; HRQoL measured using the Western Ontario and McMaster Universities Osteoarthritis Index, the 12-Item Short Form Health Survey, and EuroQoL 5-Dimension 5-Level tool; wait times; and the proportion of referrals deemed suitable candidates for surgery. Results: The most commonly used conservative treatments were pharmacotherapy, exercise and lifestyle modification. Forty percent of patients referred for TKA were deemed not to be suitable candidates for surgery. The greatest proportion of costs was borne by the patient or private insurer; a small proportion was borne by the public payer. Across all stages of care, more than 60% of the total costs was attributed to productivity losses. HRQoL remained relatively stable throughout the waiting period (mean wait time from referral to TKA 13.2 mo) but improved postoperatively. Conclusion: The suboptimal primary care management of knee OA calls for the development of innovative models of care. This study may provide valuable guidance on the design and implementation of a new online educational platform to improve referral efficiency and expedite wait times for TKA.

Contexte: Le fardeau socioéconomique croissant de l'arthrose du genou rappelle que nous avons besoin de stratégies novatrices afin de réduire les temps d'attente pour l'arthroplastie totale du genou (ATG). Le but de cette étude est d'évaluer l'utilisation des ressources, les coûts et la qualité de vie liée à la santé (QVLS) dans tout le continuum des soins pour les patients souffrant d'arthrose du genou. Méthodes: Cette étude prospective a porté sur 383 patients recrutés dans un établissement d'enseignement fort achalandé, qui en étaient à différentes étapes du continuum de soins (demande de consultation, consultation et préchirurgie). Les paramètres incluaient l'utilisation des ressources en santé, les coûts du point de vue sociétal et des régimes d'assurance maladie publics et privés, la QVLS mesurée au moyen de l'indice WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index), du questionnaire Short Form Health Survey en 12 points et de l'outil EuroQoL appliqué à 5 dimensions et à 5 niveaux, les temps d'attente, et la proportion de demandes de consultation concernant des patients considérés comme de bons candidats à la chirurgie. Résultats: Les traitements conservateurs les plus utilisés étaient la pharmacothérapie, l'exercice et les modifications à l'hygiène de vie. Quarante pour cent des patients adressés en consultation pour ATG ont été considérés comme de bons candidats à la chirurgie. La plus grande part des coûts a été assumée par le patient ou un assureur privé; une faible part des coûts a été assumée par le régime public. À toutes les étapes du continuum, plus de 60 % des coûts totaux ont été attribués à des pertes de productivité. La QVLS est demeurée relativement stable tout au long de la période d'attente (temps d'attente moyen entre la consultation et l'ATG, 13,2 mois) mais s'est améliorée après la chirurgie. Conclusion: La prise en charge sous-optimale de l'arthrose du genou en soins primaires rappelle qu'il est nécessaire d'établir des modèles de soins novateurs. Cette étude pourrait faciliter la mise au point et l'application d'une nouvelle plateforme éducative en ligne pour améliorer l'efficience des demandes de consultation et abréger les temps d'attente pour l'ATG.
