Purpose of the study and background. This audit report outlines a physiotherapy lead spinal triage program for inpatients in a private hospital. The reason to trial this model was proposed as a way to expedite the assessment of inpatients presenting with back pain and implement an appropriate and prompt management plan. Summary of the methods used and the results. An audit tool was developed to record the patient details and outcomes of referrals to the spinal triage program. Length of time between referral and triage was recorded as was the number of patients that went on to require a spinal surgeon consult and spinal intervention. A total of 75 patients were referred into Spinal Triage over a 7 month period. The majority of in patients referred for spinal consult within this private hospital setting were triaged solely by physiotherapy (56%) and a management plan decided on in conjunction with the spinal surgeon on call who could access any imaging remotely. Six patients (8%) involved in the triage program went on to have spinal surgical intervention. Conclusion. Results indicate that the majority of spinal consults at inpatient level do not proceed to require surgical intervention. These results support the model of using Physiotherapists to triage this patient group.

Microdiscectomy is the most commonly performed spine surgery in the world. Due to its technical simplicity and low complication rate, this was the first spine surgical procedure transitioning for one-day surgery. However, the economic assessment of this outpatient transition was never performed and the question on the real impact in the burden of spine care remains. This economic study aims to access the cost-utility of outpatient lumbar microdiscectomy when compared with the inpatient procedure. To do so, a cost-utility study was performed, adopting the hospital perspective. Direct medical costs were retrieved from the assessment of 20 patients undergoing outpatient lumbar microdiscectomy and 20 undergoing inpatient lumbar microdiscectomy, from a in a Portuguese NHS hospital. Utilities were calculated with quality-adjusted life-years were derived from Oswestry Disability Index values (ODI). ODI was assessed prospectively in outpatients in pre and 3- and 6-month post-operative evaluations. Inpatient ODI data were estimated from a meta-analysis. both probabilistic and deterministic sensitivity analyses were performed and incremental cost-effectiveness ratio (ICER) calculated. A willingness to pay (WTP) threshold of €60000/QALY gained with inpatient procedure was defined. Out results showed that inpatient procedure was cost-saving in all models tested. At 3-month assessment ICER ranged from €135753 to €345755/QALY, higher than the predefined WTP. At 6-month costs were lower and utilities were higher in outpatient, overpowering the inpatient procedure. Probabilistic sensitivity analysis showed that in 65% to 73% of simulations outpatient was the better option. The savings with outpatient were about 55% of inpatient values, with similar utility scores. No 30-day readmissions were recorded in either group. The mean admission time in inpatient group was 2.5 days. Since there is an overall agreement among spine surgeons that an uncomplicated inpatient MD would only need a one-day admission, an analysis reducing inpatient admission time for one day was also performed and outpatient remained cost-effective. In conclusion, as the first economic study on cost-utility of outpatient lumbar microdiscectomy, this study showed a significant reduction in costs, with a similar clinical outcome, proving this outpatient transition as cost-effective

Aims. The escalating demand for medical resources to address spinal diseases as society ages is an issue that requires careful evaluation. However, few studies have examined trends in spinal surgery, especially unscheduled hospitalizations or surgeries performed after hours, through large databases. Our study aimed to determine national trends in the number of spine surgeries in Japan. We also aimed to identify trends in after-hours surgeries and unscheduled hospitalizations and their impact on complications and costs. Methods. We retrospectively investigated data extracted from the Diagnosis Procedure Combination database, a representative inpatient database in Japan. The data from April 2010 to March 2020 were used for this study. We included all patients who had undergone any combination of laminectomy, laminoplasty, discectomy, and/or spinal arthrodesis. Results. This investigation included 739,474 spinal surgeries and 739,215 hospitalizations in Japan. There was an average annual increase of 4.6% in the number of spinal surgeries. Scheduled hospitalizations increased by 3.7% per year while unscheduled hospitalizations increased by 11.8% per year. In-hours surgeries increased by 4.5% per year while after-hours surgeries increased by 9.9% per year. Complication rates and costs increased for both after-hours surgery and unscheduled hospitalizations, in comparison to their respective counterparts of in-hours surgery and scheduled hospitalizations. Conclusion. This study provides important insights for those interested in improving spine care in an ageing society. The swift surge in after-hours spinal surgeries and unscheduled hospitalizations highlights that the medical needs of an increasing number of patients due to an ageing society are outpacing the capacity of existing medical resources.

Aims. With resumption of elective spine surgery services in the UK following the first wave of the COVID-19 pandemic, we conducted a multicentre British Association of Spine Surgeons (BASS) collaborative study to examine the complications and deaths due to COVID-19 at the recovery phase of the pandemic. The aim was to analyze the safety of elective spinal surgery during the pandemic. Methods. A prospective observational study was conducted from eight spinal centres for the first month of operating following restoration of elective spine surgery in each individual unit. Primary outcome measure was the 30-day postoperative COVID-19 infection rate. Secondary outcomes analyzed were the 30-day mortality rate, surgical adverse events, medical complications, and length of inpatient stay. Results. In all, 257 patients (128 males) with a median age of 54 years (2 to 88) formed the study cohort. The mean number of procedures performed from each unit was 32 (16 to 101), with 118 procedures (46%) done as category three prioritization level. The majority of patients (87%) were low-medium “risk stratification” category and the mean length of hospital stay was 5.2 days. None of the patients were diagnosed with COVID-19 infection, nor was there any mortality related to COVID-19 during the 30-day follow-up period, with 25 patients (10%) having been tested for symptoms. Overall, 32 patients (12%) developed a total of 34 complications, with the majority (19/34) being grade 1 to 2 Clavien-Dindo classification of surgical complications. No patient required postoperative care in an intensive care setting for any unexpected complication. Conclusion. This study shows that safe and effective planned spinal surgical services can be restored avoiding viral transmission, with diligent adherence to national guidelines and COVID-19-secure pathways tailored according to the resources of the individual spinal units.

Purpose of the study and background. An integrated rehabilitation programme was developed and found feasible taking into account the existing evidence base, appropriate theories, and patient and public involvement. The integrated programme encompasses inpatient activities supported by a multidisciplinary team, and integration of knowledge, skills and behaviours in the patient's everyday life. The aim of this trial was to compare the effectiveness of an integrated rehabilitation programme with an existing rehabilitation programme in patients with chronic low back pain (CLBP). Methods and Results. Comparison of two parallel rehabilitation programmes in a randomised controlled trial including 165 patients with CLBP. The integrated rehabilitation programme comprised an alternation of in total three weeks of inpatient stay and in total 11 weeks of home-based activities. The existing rehabilitation programme comprised a four-week inpatient stay. Primary outcome was changes in disability (Oswestry Disability Index). Secondary outcomes were changes in pain, pain self-efficacy, health related quality of life and depression. Outcomes were collected at baseline and 26-week follow-up. Disability decreased −5.76 (95%CI; −8.31, −3.20) for the integrated programme and −5.64 (95%CI; −8.45, −2.83) for the existing programme. The adjusted difference between the two programmes was −0.28 (95%CI; −4.02, 3.45). No statistically significant difference was found in any of the secondary outcomes. Conclusion. The results of the trial were consistent, showing no significant differences in patients' outcomes when comparing an integrated rehabilitation programme with an existing programme.

Background. Advances in surgical and anesthetic technique have resulted in a reducing length of stay for lumbar decompression, with the first day case procedure published in the literature in 1980. Current evidence suggests day case surgery is associated with improved patient satisfaction, faster recovery, reduced infection rates and financial savings. Following the introduction of a locally agreed day case protocol for lumbar microdiscectomy, we reviewed our 30-day postoperative complication rates. Aims. To review postoperative complication rates for patients who underwent day case primary lumbar microdiscectomy. Methods. We studied all patients that met a locally agreed day case protocol for lumbar microdiscectomy and were operated upon between 1. st. March 2013 and 31. st. December 2015. Results. 134 patients underwent primary day case microdiscectomy (70 males, 64 females). The cohort had a mean age of 41 years (16–82). 96% (n=129) were single level procedures, 93% were unilateral (n=125). 81% (n=109) took place at either L4/L5 or L5/S1. All patients were discharged on the same day as admission and operation. 3% (n=4) of patients re-presented to hospital within 30 days of which 75% (n=3) were reviewed and discharged from the emergency department within 4 hours, following a satisfactory clinical review. One patient required an inpatient stay for a washout of a superficial postoperative infection. Conclusion. This study demonstrates that with adherence to robust listing and discharge protocols, day case lumbar microdiscectomy can be safely performed. Our 30-day postoperative complication rate of under 1% is comparable to that of traditional inpatient primary lumbar microdiscectomy. No conflicts of interest. No funding obtained

Aims

People with severe, persistent low back pain (LBP) may be offered lumbar spine fusion surgery if they have had insufficient benefit from recommended non-surgical treatments. However, National Institute for Health and Care Excellence (NICE) 2016 guidelines recommended not offering spinal fusion surgery for adults with LBP, except as part of a randomized clinical trial. This survey aims to describe UK clinicians’ views about the suitability of patients for such a future trial, along with their views regarding equipoise for randomizing patients in a future clinical trial comparing lumbar spine fusion surgery to best conservative care (BCC; the FORENSIC-UK trial).

The aim of this study was to prospectively assess the outcome of patients with metastatic spinal disease who underwent minimally invasive fixation of the spine for intractable pain or spinal instability. This is a prospective audit of patients with metastatic spinal cord disease who have undergone minimally invasive fixation of the spine from August 2009 until the present date. This was assessed by pre and post-operative Oswestry Disability Index (ODI), EQ5D and Tokuhashi scores. Intra- and post-operative complications, time to theatre, length of inpatient stay, analgesia requirements, mobility, chest drain requirement and post-operative HDU and ITU stays were also recorded. So far, 10 patients have met the criteria. There were no intra-operative complications. Post-operatively, there were no complications, chest drains, increase in analgesia or stay on the HDU or ITU. All patients showed an improvement in mobility. The mean post-operative day of mobilisation was 2 days, post-operative days until discharge 5.3 days and length of inpatient stay was shorter than traditional surgery. Blood loss was minimum except one patient with metastatic renal cell carcinoma who needed transfusion intraoperatively. ODI, VAS and EQ-5D scores were calculated and were significantly improved compared to preoperatively. This novel approach to management of metastatic spinal disease has resulted in improved mobility, short inpatient stays without the need for chest drains, HDU or ITU and an improved the quality of life in pallliative patients. This is a completely new strategy to treat the pain in these patients without the usual associated risks of surgery and has major advantages over traditional surgical techniques which may preclude this group of patients having any surgical stabilisation procedure at all

To examine the impact of a structured rehabilitation programme as part of an integrated multidisciplinary treatment algorithm for adult spinal deformity patients. A prospective cohort study was performed over a 2-year period at a major tertiary referral centre for adult spinal deformity surgery. All consecutive patients requiring 2-stage corrective surgery for sagittal malalignment were included (n=32). Details of physiotherapy initial evaluation, inpatient rehabilitation progress, details of bracing treatment and time to discharge were collected. Clinical outcome scores were measured preoperatively and at 6 weeks, 6 months and 1 year postoperatively. After second stage corrective surgery, the mean time to standing without assistance was 2.1 days, mean time to independent ambulation was 4.2 days, mean time to competent ascending and descending stairs was 5.6 days and mean time to moulded orthosis application 7.1 days. Successful progression through the structured rehabilitation programme was associated with high clinical outcome scores and improved health related quality of life (HRQOL). The introduction of this programme contributed to the development of an enhanced recovery pathway for patients having adult spinal deformity surgery, reducing inpatient length of stay and optimising clinical outcomes

Aims

Historically, patients undergoing surgery for adolescent idiopathic scoliosis (AIS) have been nursed postoperatively in a critical care (CC) setting because of the challenges posed by prone positioning, extensive exposures, prolonged operating times, significant blood loss, major intraoperative fluid shifts, cardiopulmonary complications, and difficulty in postoperative pain management. The primary aim of this paper was to determine whether a scoring system, which uses Cobb angle, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and number of levels to be fused, is a valid method of predicting the need for postoperative critical care in AIS patients who are to undergo scoliosis correction with posterior spinal fusion (PSF).

Aims

Psychoeducative prehabilitation to optimize surgical outcomes is relatively novel in spinal fusion surgery and, like most rehabilitation treatments, they are rarely well specified. Spinal fusion patients experience anxieties perioperatively about pain and immobility, which might prolong hospital length of stay (LOS). The aim of this prospective cohort study was to determine if a Preoperative Spinal Education (POSE) programme, specified using the Rehabilitation Treatment Specification System (RTSS) and designed to normalize expectations and reduce anxieties, was safe and reduced LOS.

Increasing numbers of posterior lumbar fusions are being performed. The purpose of this study was to identify trends in demographics, mortality and major complications in patients undergoing primary posterior lumbar fusion. We accessed data collected for the Nationwide Inpatient Sample for each year between 1998 and 2008 and analysed trends in the number of lumbar fusions, mean patient age, comorbidity burden, length of hospital stay, discharge status, major peri-operative complications and mortality. An estimated 1 288 496 primary posterior lumbar fusion operations were performed between 1998 and 2008 in the United States. The total number of procedures, mean patient age and comorbidity burden increased over time. Hospital length of stay decreased, although the in-hospital mortality (adjusted and unadjusted for changes in length of hospital stay) remained stable. However, a significant increase was observed in peri-operative septic, pulmonary and cardiac complications. Although in-hospital mortality rates did not change over time in the setting of increases in mean patient age and comorbidity burden, some major peri-operative complications increased. These trends highlight the need for appropriate peri-operative services to optimise outcomes in an increasingly morbid and older population of patients undergoing lumbar fusion.

Purpose. This review aims to explore the methodologies used for estimating the direct and indirect costs attributed to back pain in developed countries. Methods. Six databases were searched to uncover studies about the direct and indirect costs of back pain published in English upto November 2016. Data extracted included study characteristics, cost categories and analysis methods. Results were synthesised descriptively. Results. The search identified 8009 potential studies, of which 40 were included for data extraction. The included studies reported data from 14 industrialised countries with considerably varying methodologies. Most of the studies (n=25) followed a retrospective study design and cost perspective was largely societal (n=26). Nearly half of the selected studies included indirect costs in their analysis as well as direct costs; and the proportion of indirect costs in most of the studies far outweighed the direct costs (3:1 ratio). The analysis method used most frequently was the top-down approach (n=13) followed by bottom-up approach (n=7) and econometric methods (n=7). Inpatient costs and absenteeism costs were the most important cost drivers accounting for 12%−35% of the direct costs and 5%−67% of the indirect costs respectively. The healthcare costs associated with back pain in the UK were estimated at £1.6 billion in 1998 while the indirect costs ranged from £5 billion to £10.7 billion. Conclusions. This is the first methodological systematic review assessing the costs of back pain. Despite differences in methodology, the economic burden of back pain is significant. Development of guideline and standardisation of methodologies is needed for future studies. Conflict of interest: None. Sources of funding: None

Aims

The aim of this study was to identify the risk factors for adverse events following the surgical correction of cervical spinal deformities in adults.

The National Inpatient Register and the Swedish Death Register were linked to determine the incidence of surgical intervention, the trends and characteristics of the patients, the death rate and the pre- and post-operative admissions for herniation of a lumbar disc based on comprehensive national data between 1987 and 1999. There were 27 576 operations which were followed cumulatively for 155 249 years, with a median of 6.0 years. The mean annual rate of operation was 24 per 100 000 inhabitants, the median age of the patients was 42 years. The 30-day death rate was 0.5 per 1000 operations. The rates of re-operation at one and ten years were 5% and 10%, respectively, decreasing significantly (40%) with time. The mean length of stay decreased from nine to five days. Patients who had been in hospital because of a previous spinal disorder had a significantly higher risk of readmission

We have assessed the influence of somatisation on the outcome of treatment in 81 patients with chronic low back pain. All, irrespective of whether treatment was surgical or conservative, had a significantly better (p < 0.001) health-related quality of life at follow-up on all but one scale of the SF-36. Lower health-related quality of life at follow-up correlated significantly with a higher tendency to somatise before treatment and at follow-up. A logistic regression analysis yielded two factors which predicted the outcome; somatisation (p < 0.001) and ‘doctor shopping’ (the number of physicians consulted before the present inpatient treatment, p < 0.001). These factors accurately distinguished between patients with good and those with poor outcomes in 82%. Patients with somatisation and ‘doctor shopping’ were at a higher risk for a poor outcome. The results show the relevance of somatisation in the outcome of treatment in patients with low back pain

Introduction. One of the most complicated problems of orthopaedics is the treatment of scoliosis. More than 90% of cases are attributable to idiopathic deformation, the cause of which is unknown. We investigated the cause and pathogenesis of this disorder. Methods. At our institution, more than 6900 patients aged 1–89 years have undergone inpatient and outpatient treatment in connection with spinal pain syndrome and different neurological disorders associated with idiopathic scoliosis. This study was undertaken between February, 1996, and February, 2010. All patients had had clinical, radiographic, and laboratory examinations. Results. 29·6% of patients were aged 31–50 years; 60% were men and 40% women. While examining patients with scoliosis deformation we noted symptoms of body asymmetry–ie, different volumes of right and left halves of face, body, and limbs. These features were typical for all patients irrespective of sex, age, and ethnic origin. 83·2% of patients had underdevelopment of left part of the body, and only 16·8% the right side. Analysis of published work in anatomy, physiology, neurophysiology, and vertebrology, done simultaneously with analysis of clinical material, allowed us to make some conclusions. Conclusions. First, asymmetrical structure of human body is based on laws of nature and is linked with difference of sizes and activity of brain's hemispheres, particularly of right or left gyrus centralis anterior, which control the muscle's function and our movements. Second, asymmetrical tension of Erector spinae muscles leads to inclination of the pelvis on a side of weak muscles; thus initiating development of lateral spine curves. Since such a situation is typical for all people, this deformation is known as functional scoliosis. Third, further development of bodies of vertebrae, their arches, processes, intervertebral discs, ligaments, and other anatomical elements in position of deviation leads to one-sided underdevelopment of these structures. As a result, areas of instability appear in each segment of spine (neck, chest, lumbar, and sacral areas). Fourth, the muscles in a growing body misbalance and on the ground of rotating movement start rotatory dislocation of vertebrae in zones of instability in all parts of the spine. As a result, torsion of deformed wedge-shaped vertebrae leads to formation of structural scoliosis. Rotation of vertebrae, described above, does not depend on sex, age, and ethnic origin of a patient and has a character of natural development. Thus, from our point of view, the term idiopathic scoliosis must be changed to spinal muscle asymmetrical deformation of a reflex origin. Understanding of this rotation allowed us to establish an effective non-surgical method of treatment of scoliosis and spinal pain syndrome in patients of all ages

Aims

HIV predisposes patients to opportunistic infections. However, with the establishment of Highly Active Anti-Retroviral Therapy (HAART), patients’ CD4 counts are maintained, as is a near normal life expectancy. This study aimed to establish the impact of HIV on the bacteriology of spondylodiscitis in a region in which tuberculosis (TB) is endemic, and to identify factors that might distinguish between them.

Aims

There is little information about the optimum number of implants to be used in the surgical treatment of idiopathic scoliosis. Retrospective analysis of prospectively collected data from the Swedish spine register was undertaken to discover whether more implants per operated vertebra (implant density) leads to a better outcome in the treatment of idiopathic scoliosis. The hypothesis was that implant density is not associated with patient-reported outcomes, the correction of the curve or the rate of reoperation.

Aims

The aim of this study was to determine whether the sequential application of povidone iodine-alcohol (PVI) followed by chlorhexidine gluconate-alcohol (CHG) would reduce surgical wound contamination to a greater extent than PVI applied twice in patients undergoing spinal surgery.
