The following data were gathered: age, sex, diagnosis, previous analgesic treatments, pain intensity, localization and area of pain, concomitant pain medication, indicators of feasibility, health state and adverse events related to the capsaicin patch as well as the effectiveness of the capsaicin patch.
Given the chaotic nature of the ED, there will be patients during a study shift who will not be approached for the study by the RA for these 'missed' patients we will gather age, sex, presenting complaint, triage level and discharge disposition (through retrospective chart review).
The following variables were gathered: age, gender, history of hypertension, need for cardiopulmonary resuscitation, need for intracranial surgery, use of vasopressor support, use of antidiuretic hormone (ADH), plasma creatinine level, length of hospital stay before brain death diagnosis, cause of death and multiorgan or kidney-only donation.
We also desired to gather age-matched normal people as control group to enhance the effectiveness of comparative studies.
Additionally, the European Sero-Epidemiology NESENrk (ESEN), was set up in 1996 to gather age-stratified immunity data for measles (and other diseases) in Italy, the UK, Denmark, France, Germany, and the Netherlands, although, being based on residual sera, the data does not form a random cross-sectional survey [ 9, 11].
Information was gathered on: age of patient, underlying aetiology, radiation dose, date of surgery, date of first radiograph and adequacy of radiographs.
Data was gathered on age, gender, analgesic method, pain scores, analgesia failure, vasopressor use, highest arterial lactate within 24 h, unit LOS and readmission rates.
