Communication between an occupational physician and other medical practitioners--an audit

Four hundred and seventy-two consecutive referral episodes relatingto 386 patients attending the Occupational Health Departmentof a general teaching hospital were analyzed to evaluate thefrequency, content and effect on management of communicationsbetween the occupational physician and other doctors. In all,250 episodes (53%) were associated with such a communication.The likelihood of a communication was strongly influenced byreason for referral, particularly in respect of long or shortterm sickness absence; univariate odds ratios (OR)=10.58, 95%Cl=8.13–27.08) and 2.65, 95% Cl=1.55–4.60) respectively;a medical diagnosis of psychiatric illness (OR=3.17, 95% Cl=1.69–5.97));and by number of consultations. Communication was also morelikely when the occupational outcome was ill health retirement,rehabilitation in work or modified work. Ninety-eight per centof specific requests for information or an opinion eliciteda reply. Information received from other doctors influencedthe occupational health physician's management in 52 referralepisodes (20%). Specific action by GPs as a result of communicationwas documented in 54 and by specialists in 37 episodes. Theimportance of communication between occupational health physicianand other doctors in the occupational health process is confirmed.     

Interviewing skills: self-evaluation by medical students

In an independent learning project, 52 third-year medical students carried out a structured self-assessment of two videotaped psycho-social interviews they had conducted with volunteer clients 1 year earlier, as part of a previous course. The interviews had been conducted in small tutorials with feedback from their clients, fellow students and tutors, facilitated by videotape playback. During the sequence of 16 tutorials each student had carried out an early and a late interview and had observed and participated in the discussion of the interviews of 14 peers. Students were asked to tally the frequencies of various interview behaviours, to evaluate the quality of their behaviours, and to establish priorities for future learning. The videotapes were also reliably rated by an independent observer. Students' overall self-assessments correlated 0.46 with those of the independent observer. This correlation was higher than is typically reported in studies of the validity of self-assessment. In absolute terms, the students' mean rating of interviewing performance was 3.2 (adequate plus) which was significantly lower than the observer's mean of 3.6 (adequate to good). Results are discussed in terms of Gordon's (1992) two recommendations for improving the validity of self-assessments and two further suggestions, for paired comparisons and low-threat learning environments, are added.

The Effect of 50 Hz External Electrical Interference on Implanted Cardiac Pacemakers

The effects of injected 50 Hz alternating current on the function of cardiac pacemakers has been observed in 18 patients with implanted unipolar VVI units. Current, in the range 0-600 microA was applied via electrodes attached to the patients' upper body and feet and fed from a specially designed current injection unit at the bedside. Most implanted pacemakers reverted to interference mode in the current range 29-250 microA. At current levels just below the reversion current all units developed irregular and inappropriate pacing. This current level was pacemaker dependent and varied in the range 27-246 microA. The total reversion current depended on the location of the injecting electrodes and on the patients' posture. The sensitivity of the units to injected interference was increased by deep inspiration. Temporary pacing catheters fitted to an additional ten patients were used to monitor the interference voltage which would be sensed by an implanted unit. This voltage was similarly dependent on patient posture and on deep respiration. Current injection has proved to be a safe, controllable and reproducible method of testing the sensitivity of implanted pacemakers to 50 Hz external interference.     

"Are You Talking to Me?" Confronting Behavioral Disturbances in Patients With Headache

The famous question, "Are you talking to me?," was coined by Robert DeNiro in his lead role as Travis Bickle in the Martin Scorsese classic, Taxi Driver . The phrase also characterizes the troubling encounters that many headache-treating professionals confront as they attempt to discuss serious matters of care and compliance with some of their headache patients. Although most headache patients are eager to take professional advice and guidance, there exists a minority of patients whose behavior undermines a collaborative relationship between doctor and patient. In these cases, the physician may need to directly confront this behavior in order to overcome behavioral barriers that interfere with desirable treatment outcomes. This article offers explicit means and strategies to engage difficult patients, increase the likelihood of program adherence and improvement, and develop a more satisfying doctor-patient relationship, based on clinical experience in a national referral center for difficult-to-manage headache patients.     

Multicultural Health Care in Practice

This study presents a first assessment of the challenges faced by Dutch health care providers dealing with the increasing cultural diversity in Dutch society. Qualitative interviews with 24 Dutch caregivers and policy-makers point to a number of important difficulties encountered when confronted with the growing diversity of patient populations. The study focuses explicitly on the challenges health care providers perceive in their direct interactions with patients. On the basis of the observations of the 24 respondents five strategies were formulated to improve the delivery of care in a multicultural environment. Their findings were further evaluated by confronting the empirical data with care-ethical notions (attentiveness, responsibility, competence, and responsiveness) and intercultural communication-theory.     

INTRAOPERATIVE BLEEDING IN ENDOSCOPIC SUBMUCOSAL DISSECTION IN THE STOMACH AND STRATEGY FOR PREVENTION AND TREATMENT

To control intraoperative bleeding is an important key to successful endoscopic submucosal dissection. The distribution of submucosal vessels encountered during the procedure differ in places in the stomach and are roughly categorized into three groups: those located in the antrum, those in the lesser curvature, and those on the anteroposterior corpus wall which consists of oblique muscle layers. Therefore, knowledge of a suitable setting of diathermy and adjusted depth of dissection in the submucosal layer for each site is imperative. The combination of utilizing the distal attachment forced or swift coagulation (trimming with coagulation mode) have enable the treatment with an insulation tipped knife safer.     

Radiofrequency Procedures

Abstract:   Radiofrequency is a minimally invasive, target-selective technique that has been in clinical use for more than 25 years and has demonstrated success at reducing pain in several chronic pain conditions, including trigeminal neuralgia, chronic low back pain, postherpetic neuralgia, and complex regional pain syndrome. However, the success of radiofrequency in chronic pain has not been adequately reproduced in good-quality, randomized controlled trials, and its use in the management of neuropathic pain is under some debate. In addition, conventional radiofrequency occasionally leads to worsening and even new onset of neuropathic pain. Nevertheless, clinical experience suggests that radiofrequency may be a useful tool in the overall management of refractory neuropathic pain. Pulsed radiofrequency in particular is a minimally destructive procedure that may offer new opportunities and a broader perspective for therapy with radiofrequency.
