The rapid access palliative radiotherapy program: blueprint for initiation of a one-stop multidisciplinary bone metastases clinic.

GOALS OF WORK: Radiotherapy (RT) for palliation of pain due to bone metastases (BM) is effective but underutilized likely due to the traditional practice of separate clinic visits for consultation, treatment planning, and RT delivery. However, recent evidence proves one RT treatment is as effective as multiple for analgesia, enabling investigation of an alternative model of RT delivery, the rapid access palliative radiotherapy program (RAPRP). MATERIALS AND METHODS: Prior to the start of the program, needs assessment was performed to determine the composition of the optimal team. Screening tools were implemented to streamline holistic, multidisciplinary assessment. An advertising strategy, treatment and research protocols, and mechanisms for patient feedback were established. After RAPRP implementation, patient outcomes such as symptom relief were tracked. MAIN RESULTS: Eighty-six patients with painful BM were referred over the 25-week pilot. Median age was 69.9 years; 64% had prostate cancer, and median performance status was 70. Patient-rated pain was on average 6.1/10 at baseline, improving to 2.6/10 by week 4 post-RT. On average, 6.2 symptoms were reported (baseline) compared to 5.2 (week 4). Team members assessed 10-100% of patients and were successful in stabilizing or improving all symptoms in >75% contacted at week 4. One hundred percent of patients surveyed were satisfied with their experience. CONCLUSIONS: Early needs assessment was advantageous in determining the optimal team and methods of assessment for our 'one-stop' BM clinic. This approach was successful in improving pain and other symptoms, and the convenience of seeing multiple providers on 1 day was appreciated by the patients.

Secondary impairments after spinal cord injury: a population-based study.

OBJECTIVE: To determine the prevalence of secondary impairments among individuals with long-standing spinal cord injury in Quebec and the potential relationships between these impairments and several variables. DESIGN: A review of 2,200 medical files was conducted to determine the target population; 976 patients were selected randomly and mailed questionnaires. The results were based on 482 individuals with spinal cord injury who returned the completed questionnaire. The questionnaire included 14 subsections, such as sociodemographic, medical, psychosocial, and environmental information. The medical section, including the type and level of lesion and the presence of secondary impairments, was analyzed. RESULTS: Urinary tract infection, spasticity, and hypotension were the most frequently reported secondary impairments, regardless of the severity of injury. Relationships between the prevalence of secondary impairments and the duration of injury, as well as perceived health status, were observed. CONCLUSIONS: This is the first study to describe secondary impairments after long-standing spinal cord injury in Quebec. Patients with spinal cord injury still present a high prevalence of secondary impairments many years after their rehabilitation, despite preventive education or medical follow-up visits. Further studies are required to determine the specific impact that these impairments have on the patients' social role and their quality-of-life.

A two-center study evaluating the hemodynamic and pharmacodynamic effects of cisatracurium and vecuronium in patients undergoing coronary artery bypass surgery.

OBJECTIVE: To determine the hemodynamic and pharmacodynamic effects of rapid bolus administration of cisatracurium compared with vecuronium. DESIGN: A randomized, prospective, double-blind study. SETTING: Tertiary-care university hospitals. PARTICIPANTS: Seventy-nine adult patients with diagnosed coronary artery disease (CAD). INTERVENTION: Elective coronary artery bypass graft surgery (CABG). MEASUREMENTS AND MAIN RESULTS: Patients were randomly divided into four groups. Patients received a rapid bolus of two or four times the 95% peak depression of twitch (ED95) of either cisatracurium (groups 1 and 2) or vecuronium (groups 3 and 4). Three minutes after a midazolam induction, all patients received a rapid bolus administration of either study drug. Maintenance of anesthesia was with a standardized propofol-sufentanil-oxygen anesthetic. Patients were monitored with radial and pulmonary artery catheters and electromyography. End points of the study were hemodynamic stability at induction, after bolus administration of study drugs, and after intubation; the quality of intubating conditions; drug interventions to correct hemodynamic instability; the onset, duration, and recovery of neuromuscular function; and drug cost. Mean arterial pressure (MAP) and heart rate (HR) decreased in a similar proportion in all four groups after induction while, following study drug administration, MAP and HR did not change significantly. Both cisatracurium groups required more boluses to maintain neuromuscular block, but spontaneous recovery rates were faster. Both agents, but cisatracurium to a lesser degree, showed increased duration with repeated maintenance doses. Both agents afforded good to excellent intubating conditions, but the cost of cisatracurium was significantly less. CONCLUSION: The authors conclude there is no evidence of a hemodynamic difference between the two neuromuscular blocking drugs (NMBDs). There are some clinical and cost advantages in favor of cisatracurium.

Propofol or midazolam for sedation and early extubation following cardiac surgery.

PURPOSE: The purpose of this randomized, double-blind study was to evaluate the efficacy of midazolam and propofol for postoperative sedation and early extubation following cardiac surgery. METHODS: ASA physical status II-III patients scheduled to undergo elective first-time cardiac surgery with an ejection fraction > 45% were eligible. All patients received a standardized sufentanil/isoflurane anaesthesia. During cardiopulmonary bypass 100 micrograms.kg-1.min-1 propofol was substituted for isoflurane. Upon arrival in the Intensive Care Unit (ICU), patients were randomized to either 10 micrograms.kg-1.min-1 propofol (n = 21) or 0.25 microgram.kg-1.min-1 midazolam (n = 20). Infusion rates were adjusted to maintain sedation within a predetermined range (Ramsay 2-4). The infusion was terminated after four hours. Patients were weaned from mechanical ventilation and their tracheas extubated when Haemodynamic stability, haemostasis, normothermia and mental orientation were confirmed. Haemodynamic measurements, arterial blood gas tensions and pulmonary function tests were recorded at specified times. RESULTS: There were no differences between the two groups for the time spent at each level of sedation, number of infusion rate adjustments, amount of analgesic and vasoactive drugs, times to awakening and extubation. The costs of propofol were higher than those of midazolam. There were no differences in haemodynamic values, arterial blood gas tensions and pulmonary function. CONCLUSION: We conclude that midazolam and propofol are safe and effective sedative agents permitting early extubation in this selected cardiac patient population but propofol costs were higher.

Hemodynamic and pharmacodynamic comparison of doxacurium and high-dose vecuronium during coronary artery bypass surgery: a cost-benefit study.

Doxacurium (DOX), a new nondepolarizing neuromuscular blocking drug (NMBD), was compared in a randomized, double-blind fashion to high-dose vecuronium (VEC) in 60 coronary artery bypass grafting (CABG) patients. A third group of 15 patients older than 70 years of age (DOX-70) was added to compare the effects of DOX to VEC in the older population. Endpoints of the study were hemodynamic stability, ease of ventilation and intubation, anesthesiologist's satisfaction, drug interventions to correct hemodynamic instability, and total cost of the drug. Anesthesia was induced with fentanyl (30 micrograms/kg) along with the NMBD (DOX 80 micrograms/kg, VEC 400 micrograms/kg) over a 2-minute period. Following induction, heart rate (HR) and mean arterial pressure (MAP) were decreased (P < 0.01) in all groups. Tracheal intubation caused the HR to return to baseline in the DOX-70 group. There was no difference in central venous pressure, pulmonary artery occlusive pressure, cardiac index, systemic vascular resistance, and drug intervention for DOX and VEC. None of the patients had evidence of myocardial ischemia. There was a statistically significant but clinically irrelevant decrease in central venous pressure and systemic vascular resistance in the DOX-70 group. The durations of the induction and maintenance doses of DOX were similar in the younger and older patients. Although the intubating dose of VEC had a faster onset of action, this had no effect on the ease of ventilation, conditions for tracheal intubation, and overall anesthesiologist satisfaction. The total cost for each NMBD was not different.(ABSTRACT TRUNCATED AT 250 WORDS)
