Is the Delay to Surgery for Isolated Hip Fracture Predictive of Outcome in Efficient Systems?

Adverse outcomes for patients with isolated hip fracture have been documented when preoperative delay is longer than 48 hours. An efficient system will have the capacity to repair all hip fractures within 48 hours. We hypothesized that in an efficient system, there would be a medical justification for a delay greater than 48 hours. The purpose of this study was to identify the causes and outcome of delay for hip surgery in an efficient system. All patients with isolated hip fracture admitted to a regional trauma center from April 1993 to March 2003 were reviewed. Demographics, presence of comorbidity, preoperative delay, complications, and mortality were collected. Univariate and multivariate analysis were carried out. The cohort included 977 patients. Overall mortality was 12.2%. Surgery was performed within 24 hours in 53% of cases and within 48 hours in 87% of cases. The presence of comorbidity partly explained longer (>48 hours) surgical delays. Multivariate analysis revealed that age greater than 65, male sex, and the presence of pulmonary and cardiac comorbid conditions or an active cancer but not surgical delay were associated with mortality and complications. However, surgical delay was associated with longer postsurgical hospital stay, independently of the presence of comorbidity or increasing age. Preoperative delay does not entail adverse outcomes when the surgery is delayed to allow for treatment of comorbid medical conditions. Preoperative delay is associated with a longer hospital stay. The presence of comorbidity only partly explains preoperative delay and adverse outcomes. A prospective study coding for the severity of comorbid conditions and the justification of the preoperative delay will be required to fully elucidate the link between delay and outcome.

Endovascular Treatment of Ruptured and Symptomatic Abdominal Aortic Aneurysms

Objective To report the experience of endovascular repair (ER) in patients with ruptured and symptomatic abdominal aortic aneurysms (rAAA and sAAA), comparing results with a cohort of controls who underwent open repair (OR) of sAAA or rAAA. Design A historically controlled cohort study. Materials Retrospective data from 21 patients who underwent ER and prospective data from 23 patients who underwent OR. Methods Results were compared using the Mann–Whitney U-test. Results Eleven ER patients had sAAAs and 10 had rAAAs. Nine OR patients had rAAAs and 13 had sAAAs. Thirty-day mortality was 11% in patients with rAAA in the ER group, and 54% in the OR group ( p=0.03). There were no post-operative deaths in the patients who had an sAAA in the ER group, and one death in the patients who had sAAA in the OR group. Results as expressed as mean ER value versus mean OR value and p-value. ER was associated with significant reductions in the length of operation (2.6 versus 3.1 h, p=0.03), blood transfusion requirements (0.86 versus 10.7 units p<0.01), time in critical care (1.5 versus 6.1 days, p=0.02), and total hospital stay (8.5 versus 17.5 days, p=0.01) compared with OR. There was no difference in time from admission to arrival in theatre between the two groups (3.4 versus 5.0 h, p=0.35). Conclusions In patients with rAAA and sAAA that are suitable for stenting, ER has reduced mortality compared with open repair. Assessment for ER does not cause a pre-operative delay, operating time is reduced, blood transfusion requirements are reduced and there is a faster recovery.

Effect of Preoperative Delay on Survival in Patients With Bladder Cancer Undergoing Cystectomy in Quebec

Effect of Preoperative Delay on Survival in Patients With Bladder Cancer Undergoing Cystectomy in Quebec: A Population Based Study

In Canada there is growing concern that waiting time for cancer surgery has been increasing. We used population based data to estimate the average PD for RC in Quebec and assess whether delayed surgery has a negative impact on long-term survival. We used the provincial billing database of the maladie du Quebec to identify all patients with bladder cancer 18 years or older who underwent RAMQ from 1990 to 2002. PD was calculated as the time elapsed between the most recent transurethral resection and the date of RC. Patients were categorized according to PD tertiles into 3 groups, namely 1) 20 or less, 2) 21 to 47 and (C) 48 days or greater. Cox proportional hazards models were used to assess the effect of PD on overall survival, while adjusting for patient and provider factors. During the study period 1,592 radical cystectomies were performed. Overall median PD was 33 days (95% CI 30 to 35). Median PD increased from 23 days in 1990 to 50 in 2002. After adjusting for calendar year, and patient and provider variables there were no significant differences in survival among the 3 delay categories. However, patients subject to greater than 12 weeks of delay were at 20% greater risk for dying (95% CI 1.0 to 1.5, p = 0.051). In line with previous reports PD greater than 12 weeks seems to be associated with a worse long-term prognosis.

Surgical Management of Trapezius Palsy

Injury to the spinal accessory nerve in the posterior cervical triangle leads to paralysis of the trapezius muscle. The aim of this study was to determine the indications for nerve repair or reconstructive surgery according to the etiology, the duration of the preoperative delay, and specific patient characteristics. Of twenty-seven patients with a trapezius palsy, twenty were treated with neurolysis or surgical repair (direct or with a graft) of the spinal accessory nerve and seven were treated with the Eden-Lange muscle transfer procedure. Lymph node biopsy was the main cause of the nerve injury. The nerve repairs were performed at an average of seven months after the injury, and the reconstructive procedures were done at an average of twenty-eight months. Nerve repair was performed for iatrogenic injuries of the spinal accessory nerve, within twenty months after the onset of symptoms, and in one patient with spontaneous palsy. Reconstructive surgery was performed for cases of trapezius palsy secondary to radical neck dissection, for spontaneous palsies, and after failure of nerve repair or neurolysis. The mean follow-up period was thirty-five months. The functional outcome was assessed clinically on the basis of active shoulder abduction, pain, strength of the trapezius on manual muscle-testing, and level of subjective patient satisfaction. The results were good or excellent in sixteen of the twenty patients treated with nerve repair and in four of the seven patients treated with the Eden-Lange procedure. Poor results were seen in older patients and in patients with a previous radical neck dissection. Good results can be expected from a repair of the spinal accessory nerve if it is performed within twenty months after the injury, as the nerve is basically a purely motor nerve and the distance from the injury to the motor end plates is short. Muscle transfer should be performed in patients with spontaneous trapezius palsy, when previous nerve surgery has failed, or when the time from the injury to treatment is over twenty months. Treatment is less likely to succeed when the patient is older than fifty years of age or the palsy was due to a radical neck dissection, penetrating injury, or spontaneous palsy.

Shoulder arthroplasty for atraumatic avascular necrosis of the humeral head: Nineteen shoulders followed up for a mean of seven years

Nineteen shoulder arthroplasties for the treatment of nontraumatic avascular necrosis of the humeral head were evaluated. The osteonecrosis was idiopathic in 6 shoulders, was a result of corticotherapy in 10, occurred after radiation in 2, and occurred after Gaucher's disease in 1. A total shoulder arthroplasty was performed in 5 cases and a hemiarthroplasty in 14. At 7 years' follow-up (range, 2 to 12 years), there were 7 excellent, 9 satisfactory, and 3 unsatisfactory results. The Constant score averaged 58 points, for an adjusted score of 78%. Radiolucent lines were present around 2 glenoid components, and 1 was radiographically loose. In 2 cases with humeral head replacement, there was painful glenoid wear. Shoulder arthroplasty for nontraumatic avascular necrosis yields satisfactory results with a pain-free shoulder in more than 80% of cases. However, limitation of motion often persists. Better results can be expected with shorter preoperative delay, when preoperative pain is moderate and range of motion preserved and when the etiology is not postradiation avascular necrosis, which in our series yielded the worst results.

Audit, guidelines and standards: Clinical governance for hip fracture care in Scotland

Purpose: To report on experience of national-level audit, guidelines and standards for hip fracture care in Scotland.Methods: Scottish Hip Fracture Audit (from 1993) documents case-mix, process and outcomes of hip fracture care in Scotland. Evidence-based national guidelines on hip fracture care are available (1997, updated 2002). Hip fracture serves as a tracer condition by the health quality assurance authority for its work on older people, which reported in 2004.Results: Audit data are used locally to document care and support and monitor service developments. Synergy between the guidelines and the audit provides a means of improving care locally and monitoring care nationally. External review by the quality assurance body shows to what extent guideline-based standards relating to A&E care, pre-operative delay, multidisciplinary care and audit participation are metConclusion: Three national-level initiatives on hip fracture care have delivered: Reliable and large-scale comparative information on case-mix, care and outcomes; evidence-based recommendations on care; and nationally accountable standards inspected and reported by the national health quality assurance authority. These developments are linked and synergistic, and enjoy both clinical and managerial support. They provide an evolving framework for clinical governance, with casemix-adjusted outcome assessment for hip fracture care as a next step.

Decision-intervention interval in ruptured uteri in Ile-Ife, Nigeria.

To determine the decision-intervention interval in ruptured uterus with a view of overhauling the management strategy thereby improving the maternal and perinatal outcome. Cross-sectional survey based on secondary data done between 1990-1999. Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. One hundred and two consecutive women who had uterine rupture. The decision-surgical intervention interval ranged from 30 minutes to 4.5 hours. The major reason for delay was unavailability of compatible blood (88.2%), followed by lack of electricity (4.9%), unsterile instruments (3.9%), waiting for ambulance to get senior obstetricians (2.9%), delay in arrival of anaesthetist (1.9%) and neonatologists (1.9%). The peri-natal mortality rate (PNMR) was 843 per 1000 total births and maternal mortality rate (MMR) 4902 per 100,000 births. The maternal and perinatal outcome in uterine rupture would be improved by early diagnosis and avoidance of preoperative delay through availability of essential obstetric services.

Predicting survival after treatment for fracture of the proximal femur and the effect of delays to surgery

Background and Objectives: The aim of this study was to evaluate the prognosis after treatment for femoral neck fracture, to assess the impact of delay to surgery, and to devise a clinical prediction rule and score.Methods: A prospective observational study was conducted in which 1780 patients treated surgically in two teaching hospitals between 1 November 1997 and 31 October 1999 were followed over 12 months. Logistic regression was used to distinguish the effects of predictor variables on survival. Using a probit transformation of the predicted posterior probabilities of death, a prognostic score was devised with scores constrained so that a nominal score of approximately 90 represented a 50:50 chance of survival over 12 months.Results: Mortality was 30.1% in men and 19.5% in women. Increasing age, male gender, longer pre-operative delay, a higher American Society of Anesthesiology score, a lower Mental Test score, and a lower activities of daily living (Barthel) score were associated with increased risks of death. Of those waiting between 1 and 5 days for surgery, approximately 8 medium-risk and 17 high-risk patients (with prognostic scores of 90 and 120, respectively) would have to have their delay reduced to <24 hours to yield one additional survivor.Conclusion: The application of prediction rules must be guided by ethical, social, and scientific concerns.

The added cost of urgent cholecystectomy to health systems.

The purpose of this study is to assess the cost and reimbursement differential between elective and urgent laparoscopic cholecystectomy. All visits for laparoscopic cholecystectomy (ICD-9 Code 51.23) to the University of Michigan Health System were reviewed for 1997 to 2001 (n = 752). Data were obtained from the University of Michigan Data Warehouse. Patients were grouped into urgent and elective cases, and further subgrouped into complicated and uncomplicated cases based on Diagnostic Related Group (DRG) coding. Total costs were determined for 13 distinct facility cost centers with average costs greater than $10 per case. Reimbursement was also assessed. Total costs were approximately 90% higher in urgent cases. The largest contributors to increased costs were nursing care and pharmacy costs. The emergent group experienced a pre-operative delay to surgery of 1.8 days. Reimbursement was similar for both elective and urgent patients when stratified by complicated and uncomplicated DRGs. The urgency of the operation significantly elevates the costs and resource consumption associated with laparoscopic cholecystectomy. These cost differences should also be recognized when setting reimbursement premiums under risk-bearing systems, such as Medicare Diagnosis Related Group reimbursement. Consideration for including urgent operation as a comorbidity should be assessed.

Effect of preoperative delay on prognosis for patients with early stage non-small cell lung cancer

Objective: Screening for lung cancer will discover many nodules of indeterminate pathology. Observation has the theoretic risk of permitting dissemination of a localized cancer and worsening prognosis, whereas immediate evaluation of benign conditions generates morbidity and cost. This study was conducted to assess the effect of delay in surgical intervention on survival for patients with early stage non-small cell lung cancer. Methods: Records for patients with resected pathologic stage I and II non-small cell lung cancer (1989-1999) were abstracted for patient age, race, sex, medical history, date of presentation, date and type of surgical treatment, pathologic stage, and date of death or last follow-up. Kaplan-Meier survival analysis was performed to test for the effect of delay (time from presentation to surgical intervention) on survival. Results: Eighty-four patients were identified. Median age was 66 years, median preoperative interval was 82 days (range, 1-641 days), and median follow-up was 3.3 years (range, 5 days-11.9 years). Median survival was 3.7 years. Overall 5-year survival was 40%; disease-specific 5-year survival was 63%. Log-rank analysis of the effect of delay on overall survival generated a P value of.54, with an estimated hazard ratio for a 90-day delay of 1.06 (95% confidence interval, 0.87-1.30). Conclusions: For this population, we were unable to detect a significant effect of delay on prognosis. Although these results suggest that the risk of judicious observation of indeterminate pulmonary nodules might be low, the 95% confidence interval is broad. Larger sample sizes are needed to reach definitive conclusions.J Thorac Cardiovasc Surg 2003;125:108-14

Hand injuries resulting from high-pressure injection: lesions specific to industrial oil

Nineteen cases of high pressure injection injuries in the hand were treated between 1973 and 1998. Same surgical treatment plan was followed in all cases: excision of the penetration point, irrigation, debridement and synovectomy if opening of the flexor sheath was noted, and skin closure to allow early mobilisation. All cases concerned men, work injuries, and volar aspect of the hand. The elapsed time between injection and initial surgery ranged from 1 hour to 1 month with a mean of 6.5 days. Eighteen patients out of 19 were reviewed with a mean follow up of 12 years. In 11/19 cases, (58%) oil was injected. The results of oil injection cases have been analysed: the quantity of oil and the preoperative delay (if more ten hours) are associated with poor functional results or complications. Two amputations, two cases of skin necrosis at the injection point, and one case of infection are reported. One case of oleoma of the thumb is described. The specificity of injuries by industrial oil under pressure must be known: paint or white spirit are more toxic than oil which was in all cases injected in the dominant hand (no high pressure injection tool but a defect in the pipe). An important inflammatory reaction with functional sequelae is caused by foreign bodies in oil. Extraction of oil off the injured tissues is difficult because oil is not visible. A specific information is necessary for farmers and truck driver, very exposed population.

Influence of preoperative medical status and delay to surgery on death following a hip fracture.

A retrospective study of 138 patients with fractured hips was undertaken to determine if a delay to surgery beyond 24 h influenced 1-year mortality. In particular, the results of the subgroup of patients who were in the American Society of Anesthesiologists (ASA) Class 3 or 4 were considered. Patients were found using ICD-9 database information. One-year mortality data was collected from Births, Deaths and Marriages -- the New Zealand government agency that collects and stores statistics on these events. The 1-year mortality rate was 17.4%. Age, operation type and time to surgery did not significantly affect 1-year mortality. American Society of Anesthesiologists' Class 1 and 2 patients had a significantly lower 1-year mortality (5.3%) than ASA Class 3 and 4 patients (22.4%) (P = 0.02). Time to surgery did not significantly affect 1-year mortality within each ASA Class.

Resective surgery in infants and young children with intractable epilepsy

Despite the relatively high incidence of epilepsy during the first few years of life, and its documented adverse impact on development, few studies have documented the long term outcomes following epilepsy surgery in infants and young children.We report a consecutive series of 11 patients under 3 years of age who underwent excisional surgery for intractable seizures. A total of 16 resective procedures were performed, and comprised functional hemispherectomy, temporal lobectomy, and lesionectomy. The mean follow-up period was 3 years.At follow-up, 73% (8/11) were seizure-free, with over half of these patients able to cease anti-epileptic medications. Acceleration of neurodevelopment was seen in all patients in whom preoperative developmental delay was present. Quality of life was enhanced in all patients.This series confirms that excellent results can be obtained following excisional surgery in well-selected infants and young children with intractable seizures.

Delayed referral reduces the success of video-assisted thoracoscopic debridement for post-pneumonic empyema

The aim of this study was to evaluate the effect of preoperative delay on the efficacy of video-assisted thoracoscopic surgery (VATS) for post-pneumonic pleural empyema (PPE). This was a prospective study of 39 consecutive patients with PPE who were treated by VATS with curative intent over a 4-year period. Failure to obtain full lung re-expansion resulted in conversion to thoracotomy. Pre- and post-operative variables were correlated with surgical outcome. VATS debridement was successful in 16 (41%) patients while conversion to open decortication was needed in 23 patients (21 immediate, two delayed). There was no difference in the age/sex distribution of the two groups. In the failed VATS group the delay from hospital admission to operation was longer: 24 (2·1) vs. 16·6 (2·7) days (P=0·03, 95% CI 0·53–14·3 days); operating time was longer: 128·2 (7·9) vs. 86·2 (10·4) min (P=0·003, 95% CI 15·2 – 68·5 min) and post-operative stay was longer: 8·4(0·8) vs. 5·2(0·6) days (P=0·03, 95% CI 1·1–5·3 days). VATS can be used successfully to treat PPE with a faster post-operative recovery when successful than open surgery. Delayed surgical intervention decreases the success of VATS thus earlier referral for surgical intervention in PPE (ideally within 21 days) is advocated to gain its full benefits.

Active observation of children with possible appendicitis does not increase morbidity.

Attempts to maximise diagnostic accuracy and reduce unnecessary surgery have led to the hospital observation of children with suspected appendicitis but unconvincing physical signs. However, morbidity associated with perforation necessitates the prompt management of acute appendicitis and increases anxiety concerning prolonged preoperative observation. To assess the preoperative delay and subsequent complications associated with active observation of appendicitis, we reviewed the records of 378 children who had an appendicectomy performed at the Women's and Children's Hospital during a 4-year period. Active observation was associated with an overall diagnostic accuracy of 93%. The mean preoperative hospital time was 12 h. The incidence of gangrene or perforation was 32%, with a mean preoperative hospital time in this group of 7 h. In view of the short preoperative waiting time in this group, we do not believe perforation in hospital to have been a frequent occurrence. The overall incidence of postoperative infective complications was 4%, with an incidence of 12% following perforation. Children with advanced disease often have convincing signs on presentation and are not usually subjected to a significant delay. Active observation is not associated with high postoperative morbidity.

Thoracoscopic decortication: a role for video-assisted surgery in chronic postpneumonic pleural empyema

Background. We evaluated a technique of video-assisted thoracoscopic (VAT) decortication of the visceral cortex to reexpand entrapped lung in cases of chronic postpneumonic pleural empyema.Methods. A prospective cohort study of 48 consecutive patients with multiloculated postpneumonic pleural empyema in whom visceral pleural decortication was required was studied. The effect of VAT decortication on perioperative outcome and factors affecting its success were assessed.Results. Before the introduction of VAT decortication 12 patients were treated by thoracotomy (group T). In the subsequent 36 patients VAT decortication was attempted with success in 21 (group VS) but lung expansion was not observed in 15 patients (group VF) who required thoracotomy. There was no difference in the age or sex distribution of the 3 groups. Operating time was significantly longer in group T than group VS, mean difference 30.3 minutes (p = 0.001) and postoperative hospital stay was longer in group T than group VS, mean difference 2.9 days (p = 0.004). The success of VAT decortication was not related to either the delay between onset of symptoms or hospital admission and surgery; indeed the operating time decreased with increasing preoperative delay. However, success was related to increasing operative experience (p = 0.001).Conclusions. VAT decortication is a feasible new technique to achieve lung reexpansion in chronic postpneumonic pleural empyema and has perioperative benefits over thoracotomy.
