Outcomes of a Novel Spine Virtual Fracture Clinic in an Australian Tertiary Hospital.

STUDY DESIGN: This was a retrospective cohort study. OBJECTIVE: To determine the proportion of referrals diverted by the SVFC from traditional outpatient clinic management. SUMMARY OF BACKGROUND DATA: The consistent rise in demand for orthopaedic outpatient clinic services is creating marked challenges to the provision of quality care. Virtual fracture clinics for upper and lower limb fractures have reduced the burden on outpatient clinics through telephone-based management of these conditions. To date, no study describes the expansion of virtual care to the spine trauma population. METHODS: A study of spine fractures referred to the RMH Department of Orthopaedic Surgery was conducted comparing outcomes prior to (January to December 2021) and following (July 2022 to November 2023) implementation of a spine virtual fracture clinic (SVFC). The primary aim of this study was to investigate the effects of a telephone-based SVFC on outpatient clinic activity, represented by the proportion of referrals discharged without requiring in-person clinic review. Secondary aims included appointment utilisation, lost to follow-up rates, duration of care, missed or mis-diagnoses, unplanned operations and complications. RESULTS: A total of 91.9% (n=666) referrals managed by the SVFC were discharged without in-person clinic attendance. Compared to outpatient clinic management (n=150 referrals), SVFC implementation was associated with reductions in the average number of consultations per referral (1.8 versus 2.4, P<0.001), appointments not attended (5% versus 13%, P<0.001), referrals lost to follow-up (0 versus 10.7%, P<0.001) and a shorter duration of care (median 48 d versus 58 d, P<0.001). A total of 65 patients (8.1%) were redirected to in-person clinics of which three underwent surgical intervention. No diagnostic errors, complications or adverse events were identified. CONCLUSION: This study demonstrates that a SVFC is an effective and safe alternative pathway to traditional hospital-based outpatient clinics with low-risk for any adverse outcomes.

Spinal fractures in fused spines: nonoperative treatment is a reliable alternative.

INTRODUCTION: Spinal fractures in fused spines such as in ankylosing spondylitis or DISH are typically of type B or C fractures where operative treatment is recommended. The mortality rate in non-operatively treated patients is reported to be 51%. The purpose of this study was to investigate the mortality rate, complication rate and demographics of patients following non-operatively treatment in fused spine injuries. METHODS: Between 2019 and 2021, a retrospective study was conducted including all patients who presented to our trauma center with a spinal fracture of a fused spine. Radiology and patient charts were analyzed for fracture pattern, complications, neurological deficit, comorbidities, and mortality rate. RESULTS: A total of 49 patients were found at a mean age was 79.8 ± 10.9 years and primarily males were affected in 65.3%. All fractures were of type B and the thoracic spine was involved in 85.7%. The mean follow-up was 6.3 ± 8.2 months and fusion was obtained in all patients. No neurological deficit was observed in any. A total of 13 patients died at a mean age of 86.5 ± 10.0 years after 157.1 ± 158.1 days. 6 patients (10.2%) deceased within the first 6 weeks at a mean age of 91.8 ± 3.8 years. One patient each suffered from heart failure, an acute delirium, end stage colon cancer and subdural hemorrhage. CONCLUSION: This study shows that the mortality rate in the first 6 weeks following a fracture in a fused spine is 10.2% for patients above the age of 90 years. Therefore, non-operative treatment should be taken into consideration as the mortality rate in other studies may be overestimated. LEVEL OF EVIDENCE: III, retrospective study.

The impact of morphological characteristics on late outcomes in patients born with hypoplastic left heart syndrome†.

OBJECTIVES: Patients with hypoplastic left heart syndrome are at high risk of late adverse events after Fontan completion, but it is unclear whether their morphological characteristics influence these outcomes. METHODS: Retrospective review of the data from the Australian and New Zealand Fontan Registry identified 185 patients with hypoplastic left heart syndrome who survived to hospital discharge after Fontan completion. Their outcomes were reviewed to identify predictors of adverse events with a particular focus on the impact of morphological characteristics. All available echocardiographic parameters were collected, and the hypoplasia of the left ventricle was subjectively considered to be mild, moderate or severe. RESULTS: The mean follow-up after the Fontan procedure was 6.4 ± 4.7 years. The median age at Fontan procedure was 4.41 years, 95% (176/185) of patients underwent an extracardiac conduit Fontan procedure and 71% (132/185) of those were fenestrated. At 15 years after Fontan, freedom from death and cardiac transplantation was 90% [95% confidence interval (CI) 85-97], freedom from Fontan failure was 78% (95% CI 70-87) and freedom from adverse events was 32% (95% CI 22-46). Morphological parameters did not influence transplant-free survival or Fontan failure. Independent risk factors predicting higher incidence of adverse events included aortic atresia (P = 0.003). CONCLUSIONS: The long-term survival of Fontan survivors with hypoplastic left heart syndrome is excellent and appears comparable to that of the general Fontan population. However, intrinsic morphological characteristics may continue to burden patients with late morbidity.

Long-term outcomes of single-ventricle palliation for pulmonary atresia with intact ventricular septum: Fontan survivors remain at risk of late myocardial ischaemia and death.

OBJECTIVES: The specific outcomes of patients with pulmonary atresia with intact ventricular septum late after Fontan palliation are unknown. Patients with smaller right ventricles and myocardial sinusoids are known to have worse survival in the first years of life. Whether the potential for coronary ischaemia affects the long-term outcomes of these patients after Fontan palliation is still unknown. METHODS: All patients with pulmonary atresia with intact ventricular septum who underwent the Fontan procedure from 1984 to 2016 in Australia and New Zealand were identified, and preoperative, perioperative and follow-up data were collected. RESULTS: Late follow-up data were available for 120 patients. The median length of follow-up after the Fontan procedure was 9.1 years (interquartile range 4.2-15.4 years). Late death occurred in 9% of patients (11/120). Six were sudden, unexpected deaths; 4 of those occurred in patients known to have right ventricle-dependent coronary circulation (RVDCC). Those with RVDCC had a higher incidence of sudden death (4/20 vs 2/100; P = 0.007). RVDCC was associated with late death (P = 0.01) and the development of myocardial ischaemia after Fontan completion (P < 0.001). The 10-year survival rate was 77% (95% confidence interval 56-100%) for patients with RVDCC vs 96% (95% confidence interval 92-100%) for patients without RVDCC. CONCLUSIONS: Long-term survival of patients with pulmonary atresia with intact ventricular septum after the Fontan procedure is excellent, but patients with RVDCC remain susceptible to coronary ischaemia and sudden death. Closer surveillance and investigation for exercise-induced ischaemia may be necessary.
