Longitudinal trends in the treatment of abdominal pain in an academic emergency department.

BACKGROUND: Abdominal pain is a top chief complaint of patients presenting to Emergency Departments (ED). Historically, uncertainty surrounded correct management. Evidence has shown adequate analgesia does not obscure the diagnosis, making it the standard of care. OBJECTIVE: We sought to evaluate trends in treatment of abdominal pain in an academic ED during a 10-year period. METHODS: We prospectively evaluated a convenience sample of patients in an urban academic tertiary care hospital ED from September 2000 through April 2010. Adult patients presenting with a chief complaint of abdominal pain were included in this study. Analgesic administration rates and times, pain scores, and patient satisfaction at discharge were analyzed to evaluate trends by year. RESULTS: There were 2,646 patients presenting with abdominal pain who were enrolled during the study period. Rates of analgesic administration generally increased each year from 39.9% in 2000 to 65.5% in 2010 (p value for trend <0.001). Similarly, time to analgesic administration generally decreased by year, from 116 min in 2000 to 81 min in 2009 (p < 0.001). There was no improvement in mean pain scores at discharge by year (p = 0.27) and 48% of patients during the 10-year period still reported moderate to severe pain at discharge. Patient satisfaction with pain treatment increased from a score of 7.1 to 9.0 during the study period (p < 0.005), following the trend of increase in analgesic administration. CONCLUSIONS: In patients presenting to the ED with abdominal pain, analgesia administration increased and time to medication decreased during the 10-year period. Despite overall improvements in satisfaction, significant numbers of patients presenting with abdominal pain still reported moderate to severe pain at discharge.

Efficacy of high-flow oxygen therapy in all types of headache: a prospective, randomized, placebo-controlled trial.

OBJECTIVE: We aimed to assess the efficacy of oxygen inhalation therapy in emergency department (ED) patients presenting with all types of headache. METHOD: We performed a prospective, randomized, double-blinded, placebo-controlled trial of patients presenting to the ED with a chief complaint of headache. The patients were randomized to receive either 100% oxygen via nonrebreather mask at 15 L/min or the placebo treatment of room air via nonrebreather mask for 15 minutes in total. We recorded pain scores at 0, 15, 30, and 60 minutes using the visual analog scale. At 30 minutes, the patients were assessed for the need for analgesic medication. Patient headache type was classified by the treating emergency physician using standardized diagnostic criteria. RESULTS: A total of 204 patients agreed to participate in the study and were randomized to the oxygen (102 patients) and placebo (102 patients) groups. Patient headache types included tension (47%), migraine (27%), undifferentiated (25%), and cluster (1%). Patients who received oxygen therapy reported significant improvement in visual analog scale scores at all points when compared with placebo: 22 mm vs 11 mm at 15 minutes (P < .001), 29 mm vs 13 mm at 30 minutes (P < .001), and 55 mm vs 45 mm at 60 minutes (P < .001). When questioned at 30 minutes, 72% of patients in the oxygen group and 86% of patients in the placebo group requested analgesic medication (P = .005). CONCLUSION: In addition to its role in the treatment of cluster headache, high-flow oxygen therapy may provide an effective treatment of all types of headaches in the ED setting.

A randomized clinical trial comparing the effect of rapidly infused crystalloids on acid-base status in dehydrated patients in the emergency department.

STUDY OBJECTIVE: To compare the effect of normal saline (NS), lactated Ringer's, and Plasmalyte on the acid-base status of dehydrated patients in the emergency department (ED). METHOD: We conducted a prospective, double-blind, randomized trial of consecutive adult patients who presented to the emergency department with moderate-severe dehydration. Patients were randomly allocated to blindly receive normal saline (NS), lactated Ringer's or Plasmalyte at 20 ml/kg/h for 2 hours. Outcome measures of the study were pH and changes in electrolytes, including serum potassium, sodium, chloride and bicarbonate levels at 0, 60, and 120 minutes in venous blood gas samples. RESULTS: Ninety patients participated in the study and were randomized to NS (30 patients), lactated Ringer's (30 patients) and Plasmalyte (30 patients) groups. Mean age was 48±20 years and 50% (n=45) of the patients were female. All pH values were in the physiological range (7.35-7.45) throughout the study period. In the NS group there was a significant tendency to lower pH values, with pH values of 7.40, 7.37, and 7.36 at 0, 1, and 2 hours respectively. Average bicarbonate levels fell in the NS group (23.1, 22.2, and 21.5 mM/L) and increased in the Plasmalyte group (23.4, 23.9, and 24.4 mM/L) at 0, 1, and 2 hours, respectively. There were no significant changes in potassium, sodium, or chloride levels. CONCLUSIONS: NS, lactated Ringer's, and Plasmalyte have no significant effect on acid-base status and all can be used safely to treat dehydrated patients in the emergency department. However, NS can effect acidosis which might be significant in patients who have underlying metabolic disturbances; thus, its use should be weighed before fluid administration in the ED.

Communication skills training for emergency nurses.

OBJECTIVE: To determine the effects of a communication skills training program on emergency nurses and patient satisfaction. METHODS: Sixteen emergency nurses attended a 6-week psychoeducation program that was intended to improve their communication skills. The first 3 sessions of the psychoeducation program consisted of theoretical education on empathy and communication. Other sessions covered awareness, active communication, and empathic skills on a cognitive behavioral basis using discussion, role play, and homework within an interactive group. The effects of the program were assessed using a communication skills scale, empathy scale, and patient satisfaction survey and were reflected by the reduction in the number of undesirable events between nurses and patients in the emergency department. RESULTS: The mean communication skill score (177.8±20) increased to 198.8±15 after training (p=0.001). Empathy score also increased from 25.7±7 to 32.6±6 (p=0.001). The patient satisfaction survey of 429 patients demonstrated increased scores on confidence in the nurses (76.4±11.2 to 84.6±8.3; p=0.01); the nurse's respect, kindness, and thoughtfulness (72.2± 8.1 to 82.1 ± 6,5; p=0.01); individualized attention (71.3± 6.2 to 73.2 ± 9.8; p=0.2); devotion of adequate time to listening (84.6± 9.3 to 89.8 ± 7.6; p=0.03); and counseling and information delivery (71.1± 10.2 to 80.2 ± 9.7; p=0.01). The number of undesirable events and complaints during nurse-patient interactions decreased 66 % from 6 to 2. CONCLUSION: "Communication Skills Training" can improve emergency nurses' communication and empathy skills with a corresponding increase in patient satisfaction and reduction of the undesirable events and complaints during nurse-patient interactions.
