BACKGROUND: Non-image guided injection treatments (\"nerve blocks\") are commonly provided in community pain clinics in Ontario for chronic non-cancer pain (CNCP) but remain controversial.
OBJECTIVE: We explored patients\' perspectives of nerve blocks for CNCP.
METHODS: We administered a 33-item cross-sectional survey to patients living with CNCP pain attending four community-based pain clinics in Ontario, Canada. The survey captured demographic information and asked about patient experiences with nerve blocks.
RESULTS: Among 616 patients that were approached, 562 (91%) provided a completed survey. The mean age of respondents was 53 (SD 12), 71% were female, and the majority (57%) reported living with CNCP for more than a decade. Fifty-eight percent had been receiving nerve blocks for their pain for >3 years, 51% on a weekly frequency. Since receiving nerve blocks, patients self-reported a median improvement in pain intensity of 2.5 points (95% CI -2.5 to -3.0) on an 11-point numeric rating scale and 66% reported stopping or reducing prescription medications, including opioids. The majority who were not retired (62%) were receiving disability benefits and were unable to work in any capacity. When asked what impact cessation of nerve blocks would have, most employed patients (52%) reported they would be unable to work, and the majority indicated their ability to function across multiple domains would decrease.
CONCLUSIONS: Our respondents who received nerve blocks for CNCP attribute important pain relief and functional improvement to this intervention. Randomized trials and clinical practice guidelines are urgently needed to optimize the evidence-based use of nerve blocks for CNCP.

This paper conceptualizes the act of diagnosis in primary care as a \'diagnostic moment,\' comprising a diagnostic utterance in a \'diagnostic slot,\' together with a patient response. Using a dataset of 201 treated conditions drawn from 255 video recorded medical visits with 71 physicians across 33 clinical practices in the Western United States, we investigate the incidence of diagnostic moments, aspects of their verbal design, and patient responsiveness. We find that only 53% of treated conditions in the dataset are associated with a diagnostic moment. Physicians present 66% of these diagnoses as hedged or otherwise doubtful, and deliver 30% of them without gazing at the patient. In the context of these diagnostic moments, patients are non- or minimally responsive 59% of the time. These findings underscore the different significance that may be accorded diagnosis in primary care in contrast to care in other medical contexts. The paper concludes that the analysis of sequences of action which empirically realize diagnosis are underrepresented in the sociology of diagnosis, and that better understanding of the diagnostic moment would enhance our understanding of diagnostic processes in primary care.

BACKGROUND: Treatment for hidradenitis suppurativa is often empiric and inadequate, and determining which patients will respond is difficult.
OBJECTIVE: We sought to determine which patient factors are associated with a positive response to first-line medical therapy.
METHODS: A single-center retrospective cohort study of all patients with hidradenitis suppurativa seen between January 1, 1992, and October 1, 2014, was conducted. Response to first-line medical therapy (oral/topical antibiotics, intralesional corticosteroids, and topical washes) was examined at follow-up within 6 months of initiating therapy. A multivariate binary logistic regression model was built examining response to treatment and the interplay of patient factors and treatment initiated.
RESULTS: In all, 198 patients were included in the final model. Nonsmokers (odds ratio 2.634, 95% confidence interval 1.301-5.332, P = .007) and older individuals (odds ratio 1.046 for each additional year, 95% confidence interval 1.020-1.072, P < .001) were more likely to have improvement at follow-up. In addition, current smokers differed significantly from nonsmokers in several regards.
CONCLUSIONS: The retrospective nature of this study is a limitation, as is relying on classification of disease severity from physical examination findings in some patients.
CONCLUSIONS: The results of this study suggest that clinicians may be able to more accurately predict which patients with hidradenitis suppurativa will respond to first-line medical therapy, and which patients may require therapy escalation.
