Chronic Pain and Associated Factors in India and Nepal: A Pilot Study of the Vanderbilt Global Pain Survey.

BACKGROUND: Evaluation and treatment of chronic pain worldwide are limited by the lack of standardized assessment tools incorporating consistent definitions of pain chronicity and specific queries of known social and psychological risk factors for chronic pain. The Vanderbilt Global Pain Survey (VGPS) was developed as a tool to address these concerns, specifically in the low- and middle-income countries where global burden is highest. METHODS: The VGPS was developed using standardized and cross-culturally validated metrics, including the Brief Pain Inventory and World Health Organization Disability Assessment Scale, as well as the Pain Catastrophizing Scale, the Fibromyalgia Survey Questionnaire along with queries about pain attitudes to assess the prevalence of chronic pain and disability along with its psychosocial and emotional associations. The VGPS was piloted in both Nepal and India over a 1-month period in 2014, allowing for evaluation of this tool in 2 distinctly diverse cultures. RESULTS: Prevalence of chronic pain in Nepal and India was consistent with published data. The Nepali cohort displayed a pain point prevalence of 48%-50% along with some form of disability present in approximately one third of the past 30 days. Additionally, 11% of Nepalis recorded pain in 2 somatic sites and 39% of those surveyed documented a history of a traumatic event. In the Indian cohort, pain point prevalence was approximately 24% to 41% based on the question phrasing, and any form of disability was present in 6 of the last 30 days. Of the Indians surveyed, 11% reported pain in 2 somatic sites, with only 4% reporting a previous traumatic event. Overall, Nepal had significantly higher chronic pain prevalence, symptom severity, widespread pain, and self-reported previous traumatic events, yet lower reported pain severity. CONCLUSIONS: Our findings confirm prevalent chronic pain, while revealing pertinent cultural differences and survey limitations that will inform future assessment strategies. Specific areas for improvement identified in this VGPS pilot study included survey translation methodology, redundancy of embedded metrics and cultural limitations in representative sampling and in detecting the prevalence of mental health illness, catastrophizing behavior, and previous traumatic events. International expert consensus is needed.

Dexmedetomidine sedation for laryngeal framework surgery.

OBJECTIVES: Sedation for laryngeal framework surgery has lacked easy modulation between appropriate pain control, airway protection, and the alertness appropriate for vocal testing. Our objective was to determine whether dexmedetomidine hydrochloride could safely and effectively be used as the sole intravenous anesthetic agent in conjunction with local anesthesia for laryngeal framework procedures. METHODS: We undertook a prospective review of 14 patients who underwent laryngeal framework surgery with dexmedetomidine anesthesia in 2004 and 2005. All dexmedetomidine doses, sedation levels, and vital signs, including blood pressure, heart rate, respiratory rate, and oxygen saturation level, were recorded every 15 minutes by the anesthesiologist throughout the duration of the procedures. Operative conditions were noted by the surgeon, focusing special attention on airway protection, patient arousability, and patient comfort. RESULTS: Dexmedetomidine sedation produced hemodynamic and respiratory values that were maintained near preoperative values, and overall pharyngeal-laryngeal integrity provided superior operating conditions for the patient and the operating surgeon. CONCLUSIONS: We believe that dexmedetomidine provides excellent sedative and operative conditions for awake laryngeal framework procedures. Coupled with local anesthesia, dexmedetomidine produced virtually no undesirable hemodynamic or respiratory effects, while allowing for adequate sedation the majority of the time. The operative conditions were markedly improved over those of previous standard monitored anesthesia regimens.

University of Washington orthopedic resident experience and interest in developing an international humanitarian rotation.

An academic orthopedic residency program can have a significant impact on the burden of musculoskeletal disease in low- and middle-income countries. Such an exposure may also enhance the education of a resident. A 17-question electronic survey was developed to quantify the interest of orthopedic residents in pursuing an elective international rotation. The survey, which gathered resident demographic data and interest in pursuing an elective international orthopedic rotation, was sent to (and completed by) all 38 University of Washington orthopedic residents during academic year 2007-2008. More than 60% (23/38) of residents indicated they would be willing to commit to an international rotation; an additional 24% (9/38) indicated they would be very interested. Almost 40% of residents had participated in international medical volunteerism before entering residency. Among residents, there is a clear interest in pursuing an international rotation to complement their education in the United States.
