Is rural radiation oncology practice quality as good as the big smoke? Results of the Australian radiotherapy single machine unit trial

Radiotherapy utilization rates in rural Australia are suboptimal, with one solution being the building of single machine units (SMUs). One concern raised with such an approach is the quality of care delivered in SMUs. The Australian and Victorian governments have established two SMUs in the state of Victoria, with each SMU operated as a satellite service of a major ‘hub’ site. We report on the planned evaluation of practice quality. Radiation oncologist (RO) clinical practice was externally audited using the Royal Australian and New Zealand College of Radiologists Peer Review Audit instrument. This tool splits RO clinical practice into documentation/quality assurance (QA) criteria and decision‐making criteria. Over the four sites, 130 patients were randomly selected for audit. At hub sites, 79.6% of all criteria audited were adequate, compared with 84.4% of criteria audited at SMUs (P = 0.0002). This difference was largely because of better adherence to documentation/QA criteria at the SMU sites. RO decision‐making and protocol adherence were routinely very high and consistent with other clinical practice audits. There were no significant differences between hubs and SMUs for adherence to decision‐making criteria; however, the few potential deficiencies in patient care identified occurred only at the hub sites. In at least one of these cases, potential suboptimal management was as a direct result of inadequate documentation. This audit found that SMUs provide as high a standard of radiotherapeutic care as larger hub departments. The findings also emphasize the need for all departments to target clinical documentation.     

Pathology of colposcopic findings in 2635 diethylstilbestrol-exposed young women

An analysis of 6055 colposcopically directed biopsy specimens from 2635 diethylstilbestrol (DES)-exposed women and 445 biopsy specimens from 277 nonexposed women was undertaken to correlate microscopic findings with colposcopic patterns. All examinations were performed using a standardized protocol which required that each participant have colposcopy, cytologic smears, and biopsy of abnormal colposcopic lesions. The findings of colposcopic "columnar epithelium, gland openings, and Nabothian cysts" correlated most often with glandular epithelium in the biopsy specimen. "White epithelium," which includes three related colposcopic patterns, mosaicism, punctation, and white epithelium, was associated most frequently (82-93% of cases) with squamous metaplasia, but occasionally with dysplasia and carcinoma in situ (CIS)(0-6%). The presence of dysplasia or CIS in any individual biopsy specimen occurred most frequently with the observation of higher graded lesions by colposcopy or a prior diagnosis of dysplasia.     

Local Anaesthesia for Fiberoptic Intubation : A Comparison of Three Techniques

Background

The successful conduct of fiberoptic aided intubation is dependent upon effective local anaesthesia. The aim of the study was to compare three different methods of anaesthetizing the airway.

Methods

60 adult patients (American Society of Anaesthesiologists status I-III and Mallampati class III & IV), scheduled for elective surgery, received sedation followed by spraying of the nares and posterior pharyngeal wall with 4% lignocaine. Thereafter the patients received 4 ml of 4% lignocaine either by transtracheal injection (n=20, group A), via intubating fiberscope (Pentax F1-10P2) using ‘spray as you go’ technique (n=20, group B) or by nebulizer (Devilbiss 5610W) 20 min before intubation, (n=20, group C). Patients were asked to score the procedure using visual analog scale (VAS) and severity scores. Episodes of coughing, choking, stridor, extra / total local anaesthetic used and intubation times were recorded. Patients were monitored continuously for vital parameters.

Results

Group B patients showed better VAS scores with shorter intubation times and had a lower incidence of coughing and choking. The endoscopists’ VAS scores also showed a preference for group B.

Conclusion

In conclusion the ‘spray as you go’ technique was safe, provided effective local anaesthesia and was preferred by both patients and endoscopists.Key Words: Awake intubation, Difficult airway, Fiberoptic intubation     

A new guard for Kirschner wires

Means of providing adequate protective cover for Kirschner wires protruding through the skin were investigated. A new guard was developed which satisfactorily abolishes the difficulties associated with other forms of cover.     

Epidural buprenorphine for pain relief after major abdominal surgery. A controlled comparison with epidural morphine

In a controlled trial epidural buprenorphine was compared with epidural morphine as the sole means of analgesia after major abdominal surgery. Bolus injections of buprenorphine 60 micrograms in 10 ml or morphine 2 mg in 10 ml of normal saline were given on demand for the first 48 hours postoperatively. Both drugs produced significant reduction in pain scores as assessed by the linear visual analogue scale and both produced prolonged analgesia at this dosage, which could be extended by further 'top-ups'. The authors conclude that, for postoperative epidural analgesia, buprenorphine may be the opiate of choice and the reasons for this are discussed.     

The role of relaxation in systematic desensitization: Revisiting an unresolved issue

Forty-three socially anxious females received systematic desensitization, noncontiguous relaxation, hierarchy exposure only, or no treatment. Analysis of pre-posttest fear in a laboratory social interaction task revealed virtually no treatment effects on self-report or behavioral measures. Analysis of continuously monitored heart rate, however, indicated reduced anticipatory activity among subjects receiving relaxation training and reduced reactive activity for desensitization subjects.     

Pain relief following Arthroscopy - a comparative study of Intra-articular Bupivacaine,Morphine and Neostigmine

Pain after arthroscopy is quite distressing. Intra-articular bupivacaine produces transient analgesia and reports of analgesia using intra-articular opioids have produced conflicting results. Recently, spinal administration of neostigmine was shown to produce dose-dependant analgesia. However, this was limited by adverse effects. The purpose of this study was to compare the effects on intra-articular neostigmine, bupivacaine and morphine. 75 patients were randomized to receive intra-articular saline, bupivacaine, morphine, neostigmine and bupivacaine-neostigmine after arthroscopic surgery under spinal anaesthesia. Visual analog pain scores (VAS), duration of analgesia as defined as time for first demand for parenteral opioids and the total subsequent consumption of morphine was evaluated. Intra-articular bupivacaine resulted in significant VAS reduction at one and four hours as compared to those receiving intra-articular saline and morphine. Analgesia lasted longer after 500ugm intra-articular neostigmine as compared with bupivacaine, morphine or saline. The need for supplementary analgesia was lowest in the neostigmine group as compared to the other groups. No significant difference was found if bupivacaine was added to neostigmine. Among all the groups, no significant side-effects were observed.Key Words: Arthroscopy, Bupivacaine, Morphine, Neostigmine     

An interdisciplinary approach to a day-long palliative care course for undergraduate students

Although it is desirable that students in the health sciences be educated together to prepare them for interdisciplinary practice, many educational programs remain discipline specific. An undergraduate course in palliative care, originally designed for medical students at McMaster University, Hamilton, Ont., was expanded in 1993 to include students from various health sciences programs in the region. The course introduces students to the components of palliative care and its interdisciplinary nature in a problem-based way and directs students to additional educational resources. The authors describe the planning, content and evaluation of the course material. The observed decline in attendance by medical students, which coincided with the introduction of the interdisciplinary format, warrants further investigation. Future directions of the course are discussed.
