Barriers and facilitators to implementing addiction medicine fellowships: a qualitative study with fellows, medical students, residents and preceptors.

BACKGROUND: Although progress in science has driven advances in addiction medicine, this subject has not been adequately taught to medical trainees and physicians. As a result, there has been poor integration of evidence-based practices in addiction medicine into physician training which has impeded addiction treatment and care. Recently, a number of training initiatives have emerged internationally, including the addiction medicine fellowships in Vancouver, Canada. This study was undertaken to examine barriers and facilitators of implementing addiction medicine fellowships. METHODS: We interviewed trainees and faculty from clinical and research training programmes in addiction medicine at St Paul's Hospital in Vancouver, Canada (N = 26) about barriers and facilitators to implementation of physician training in addiction medicine. We included medical students, residents, fellows and supervising physicians from a variety of specialities. We analysed interview transcripts thematically by using NVivo software. RESULTS: We identified six domains relating to training implementation: (1) organisational, (2) structural, (3) teacher, (4) learner, (5) patient and (6) community related variables either hindered or fostered addiction medicine education, depending on context. Human resources, variety of rotations, peer support and mentoring fostered implementation of addiction training. Money, time and space limitations hindered implementation. Participant accounts underscored how faculty and staff facilitated the implementation of both the clinical and the research training. CONCLUSIONS: Implementation of addiction medicine fellowships appears feasible, although a number of barriers exist. Research into factors within the local/practice environment that shape delivery of education to ensure consistent and quality education scale-up is a priority.

Two birds with one stone: experiences of combining clinical and research training in addiction medicine.

BACKGROUND: Despite a large evidence-base upon which to base clinical practice, most health systems have not combined the training of healthcare providers in addiction medicine and research. As such, addiction care is often lacking, or not based on evidence or best practices. We undertook a qualitative study to assess the experiences of physicians who completed a clinician-scientist training programme in addiction medicine within a hospital setting. METHODS: We interviewed physicians from the St. Paul's Hospital Goldcorp Addiction Medicine Fellowship and learners from the hospital's academic Addiction Medicine Consult Team in Vancouver, Canada (N = 26). They included psychiatrists, internal medicine and family medicine physicians, faculty, mentors, medical students and residents. All received both addiction medicine and research training. Drawing on Kirkpatrick's model of evaluating training programmes, we analysed the interviews thematically using qualitative data analysis software (Nvivo 10). RESULTS: We identified five themes relating to learning experience that were influential: (i) attitude, (ii) knowledge, (iii) skill, (iv) behaviour and (v) patient outcome. The presence of a supportive learning environment, flexibility in time lines, highly structured rotations, and clear guidance regarding development of research products facilitated clinician-scientist training. Competing priorities, including clinical and family responsibilities, hindered training. CONCLUSIONS: Combined training in addiction medicine and research is feasible and acceptable for current doctors and physicians in training. However, there are important barriers to overcome and improved understanding of the experience of addiction physicians in the clinician-scientist track is required to improve curricula and research productivity.

Alterations in electrical pain thresholds by use of acupuncture-like transcutaneous electrical nerve stimulation in pain-free subjects.

Acupuncture-like transcutaneous electrical nerve stimulation (ALTENS) was compared with a placebo treatment in altering acute electrical pain thresholds. Ten pain-free subjects underwent, on different days, an acclimatization session, an ALTENS treatment, and a placebo treatment in a cross-over design. Electrical sensation and pain thresholds were measured from the tip of the index finger bilaterally at 15-minute intervals twice before, once during, and three times after a 30-minute treatment session. The ALTENS treatment was given at 4 Hz at an intensity just below pain threshold delivered to acupuncture points in the hand and wrist. The placebo treatment was similarly delivered, except that the intensity of stimulation was just above sensation threshold. Neither the ALTENS treatment nor the placebo treatment produced a significant change in pain threshold. There was no correlation between initial pain threshold and change in pain threshold. Implications for the modulation of pain are discussed.

Depression of hippocampal low calcium field bursts by the antiepileptic drug valproic acid.

The antiepileptic drug valproic acid (VPA) reduces the occurrence of the rhythmic and synchronous bursts produced by hippocampal neurons maintained 'in vitro' and bathed in Ringer-containing low-Ca2+ (0.2 mM), high-Mg2+ (4.0 mM). In this medium, synaptic transmission is blocked, thus demonstrating an action of VPA unrelated to potentiation of GABAergic phenomena. This conclusion is reenforced by the persistence of VPA effects in the presence of bicuculline. Also, the VPA doses effective in reducing the low-calcium synchronous burst in the hippocampal slice are similar to the free plasma levels of VPA observed to exert anticonvulsant effects in kindled rats.
