Engendering pain management practices: the role of physician sex on chronic low-back pain assessment and treatment prescriptions.
The impact of physician sex on dimensions of medical care such as treatment prescriptions and referrals has been underexplored, especially in a pain context. Also, few studies have analyzed whether physician sex moderates the influence of patients' or clinical situations' characteristics on pain management practices or its mediating processes. Therefore, our goal was to explore whether physician sex moderates the effects of patient (distressed) pain behaviors and diagnostic evidence of pathology (EP) on treatment prescriptions and referrals for chronic low-back pain, and to explore the mediating role of pain credibility judgments and psychological attributions on these effects. A total of 310 general practitioners (GPs; 72.6% women) participated in a between-subjects design, 2 (patient pain behaviors) × 2 (EP) × 2 (GP sex) × 2 (patient sex). GPs were presented with vignettes depicting a fe(male) chronic low-back pain patient, with(out) distress and with(out) EP (eg, herniated disc). GPs judged the patient's pain and the probability of treatment prescriptions and referrals. Results showed that EP had a larger effect on male than on female physicians' referrals to psychology/psychiatry. Also, GP sex moderated the pain judgments that accounted for the effect of EP and pain behaviors on prescriptions. These findings suggest framing medical decision-making as a process influenced by gender assumptions. ⋯ This paper shows that physician sex moderates the influence of clinical cues on pain management practices and the mediating role of pain judgments on these effects. It may potentially increase clinicians' awareness of the influence of gender assumptions on pain management practices and contribute to the development of more gender-sensitive services.

Pain treatment for older adults during prehospital emergency care: variations by patient gender and pain severity.
Older adults are less likely than younger adults to receive analgesic treatment during emergency department visits. Whether older adults are less likely to receive analgesics during protocolized prehospital care is unknown. We analyzed all ambulance transports in 2011 in the state of North Carolina and compared the administration of any analgesic or an opioid among older adults (aged 65 and older) versus adults aged 18 to 64. Complete data were available for 407,763 transports. Older men were less likely than younger men to receive an analgesic or an opioid regardless of pain severity. Among women with mild or moderate pain, older women were less likely than younger women to receive either form of pain treatment, but among women with more severe pain (pain score 8 or more), older women were more likely than younger women to receive pain treatment. Further, among women with mild or moderate pain, the oldest patients (aged 85 and older) were the least likely to receive any analgesic or an opioid, but among women with severe pain the oldest patients were the most likely to receive treatment. Further research is needed to assess the generalizability of this interaction between age, gender, and pain severity on pain treatment. ⋯ During prehospital care in North Carolina in 2011, older adults were generally less likely to receive pain treatment. However, older women with severe pain were more likely to receive treatment than younger women with severe pain. These results suggest an interaction between age, gender, and pain severity on pain treatment.

People with intellectual disabilities (IDs) have a higher risk of painful medical conditions. Partly because of the impaired ability to communicate about it, pain is often undertreated. To strengthen pain assessment in this population, we conducted a systematic review to identify behavioral pain indicators in people with IDs by using Embase, PubMed, PsycINFO, CINAHL, and Cochrane. Inclusion criteria were 1) scientific papers; 2) published in the last 20 years, that is, 1992 to 2012; 3) written in English, 4) using human subjects, 5) intellectual disabilities, 6) pain, 7) behavior, and 8) an association between observable behavior and pain experience. From 527 publications, 27 studies were included. Pain was acute in 14 studies, chronic in 2 studies, both acute and chronic in 2 studies, and unspecified in 9 studies. Methodological quality was assessed with the Mixed Methods Appraisal Tool. Of the 14 categories with behavioral pain indicators, motor activity, facial activity, social-emotional indicators, and nonverbal vocal expression were the most frequently reported. Most of the behavioral pain indicators are reported in more than 1 study and form a possible clinical relevant set of indicators for pain in people with IDs. Determination of a behavioral pattern specific for pain, however, remains a challenge for future research. ⋯ This review focuses on categories of behavior indicators related to pain in people with IDs. The quality of evidence is critically discussed per category. This set of indicators could potentially help clinicians to recognize pain in this population, especially when unique individual pain responses are also identified.

We examined changes in intraepidermal nerve fibers (IENFs) to differentiate patients with diabetic neuropathy (DN) and diabetic neuropathic pain (DN-P) from those with DN without pain (DN-NOP). Punch skin biopsies were collected from the proximal thigh (PT) and distal leg (DL) of normal subjects, patients with type 2 diabetes without evidence of DN (DM), or DN-P and DN-NOP patients. Protein gene product 9.5-positive (PGP+) immunohistochemistry was used to quantify total IENF, and growth-associated protein 43 (GAP43) for regenerating IENF. Compared to normal subjects and patients with type 2 diabetes without evidence of DN, both DN-P and DN-NOP have reduced PGP+ IENF densities in DL and PT. Although GAP43+ IENF densities were also reduced in DL for both DN-P and DN-NOP, the GAP43+ IENF densities in PT of DN-P remained at the control levels. Higher GAP43/PGP ratios were detected in DN-P compared to DN-NOP in the DL and PT. In parallel, increased numbers of axonal swellings per PGP+ fiber (axonal swelling/PGP) were detected in DN-P compared to normal subjects, patients with type 2 diabetes without evidence of DN, and DN-NOP in the DL. These axonal swellings were positive for tropomyosin-receptor-kinase A and substance P, suggesting that they are associated with nociception. ⋯ Among patients with DN, the ratios of GAP43/PGP and axonal swelling/PGP are likely to differentiate painful from painless phenotypes.
