Abstract
The welfare of unwanted horses presents a significant concern for the equine industry. However, there is a lack of research on how unwanted horses are affected by major crises. The drastic changes that resulted from the COVID-19 pandemic presented ample opportunity to investigate how unwanted horses are impacted by challenging circumstances. Study objectives were to evaluate the COVID-19 pandemic's impact on the unwanted horse population and determine the current perceptions of horses in-transition. A 23-question online survey designed using QualtricsTM was administered electronically to adults living in the United States. Questions pertained to effects on equine ownership, equine management, event participation, and perceptions of unwanted horses. Frequency analysis combined with Chi-squared analyses and analyses of variance identified the impacts of COVID-19 on horse owners, non-horse owners, and equine professionals. From survey results, equine ownership, management practices, and time spent with horses proved to be unaffected (P < 0.001) by the coronavirus pandemic. A decreased ability to participate in equine events was evident across all groups (P ≤ 0.03). Financial hardship, unmanageable behavior, and injury were cited as leading causes for horses becoming "in-transition." Euthanasia was the transitioning method perceived as most accessible, while donation to an equine program was least accessible. Based on results, the COVID-19 pandemic had negligible impact on the number of unwanted horses in the United States. Long-term effects of COVID-19 on equine ownership and management decisions should be considered to provide a deeper base of knowledge for how major crises affect the horse in-transition population.

Abstract
Abstract
Introduction
Falls are a major cause of morbidity and mortality in patients over 65. Unrecognised postural hypotension is a significant and treatable contributor. Training nurses and health-care assistants (HCAs) in correct measurement technique can be challenging, as these groups are rarely able to fully attend single sessions due to urgent clinical commitments, night duties and staff-shortages. We aimed to improve the frequency and quality of lying-standing blood pressure (LSBP) measurement in a Geriatric inpatient cohort.
Methods
Three PDSA cycles were performed over a 10-month period on a single Care of the Elderly ward, including an initial audit in March 2021. The outcome measures were:
1. the percentage of non-bedbound patients having LSBP correctly measured (5-min recumbent, 1 and 3-min standing readings), assessed by chart review and
2. the understanding and confidence of measurers in correct technique, as assessed by a questionnaire.
The intervention was developed into three separate days of ad-hoc mobile teaching sessions to allow reinforcement of knowledge. Trainers moved from bay-to-bay delivering a 5-minute pre-prepared presentation/demonstration on the indications and correct technique of LSBP measurement. This was repeated throughout each day until all measurers had participated.
Results
On initial assessment, only 21% (6/28) of non-bedbound patients had LSBP correctly measured. This improved to 44% (8/18) by July and 62% (8/13) by December 2021. When sampled, measurers had sustained improvements from July (n=8) to December (n=7), in terms of self-rated confidence (mean 4.4/5 vs 4.9/5), correct technique (25% vs 100%), interpretation of results (25% vs 43%) and knowledge of contraindications to measurement (88% vs 100%).
Conclusions
We describe a strategy using ad-hoc mobile teaching sessions to train nurses and HCAs to measure LSBP in a Geriatric inpatient cohort, which resulted in sustained improvements. We believe this technique is readily applicable to other units and areas of practice.

Abstract
Abstract
Introduction
There has been an increasing focus on the development of scoring systems for patients admitted following resuscitation from out-of-hospital cardiac arrest (OHCA) to determine both prognosis and short-term management. One such system, the CREST score, has been shown to predict circulatory aetiology death in patients without ST-elevation myocardial infarction, however with an increasing number of OHCAs seen, general scoring systems to predict outcome in OHCA would be helpful.
Aims
We sought to determine whether the addition of an admission lactate ≥8 mmol/l to the existing CREST score was able to better predict in-hospital mortality in patients admitted with OHCA.
Methods and results
We retrospectively analysed the data of 500 patients admitted with an OHCA of presumed cardiac origin to our tertiary cardiac centre between June 2014 and Oct 2018. Mean age was 62.6y (±14.7), 379 (76%) were male and 250 (50%) were Caucasian. 313 (62.6%) were admitted with ST elevation myocardial infarction or equivalent. 48.6% (243/500) of patients died in hospital and of those that survived, 20.2% (52/257) were left with hypoxic brain injury (CPC score 3–4).
When analysed independently, all individual factors other than history of Coronary artery disease (OR 1.47, p=0.084) significantly predicted in-hospital mortality: Admission lactate ≥8 mmol/l (OR 6.78, p<0.0001), non-shockable Rhythm (OR 10.9, p<0.0001), Ejection fraction <30% (OR 5.84, p<0.0001), Shock at presentation (OR 5.49, p<0.0001) and ischaemic Time >25 minutes (OR 12.8, p<0.0001).
When each factor was assigned one point and totalled, both increasing CREST and C-AREST scores were associated with increasing in-hospital mortality: CREST (0–5 points): 4.3%, 30.5%, 41.5%, 85.6%, 95.2%, 100% vs C-AREST (0–6 points): 9.1%, 28.3%, 41.9%, 62.8%, 97.6%, 96.4%, 100%. When analysed with stepwise logistic regression, the addition of admission lactate ≥8 mmol/l to the model improved the prediction of in-hospital mortality: CREST (40.8% of variance explained) vs C-AREST (43.3%), with admission lactate remaining an independently significant predictor (OR 3.67, p=0.002).
Conclusion
We describe a novel modification to the previously described CREST scoring system for OHCA: the C-AREST score. The addition of admission lactate ≥8 mmol/l may have a role in differentiating those in intermediate risk categories (score between 2 and 3) where the predicted in hospital mortality would otherwise vary greatly. Given the relative ease of obtaining admission lactate, this scoring system may further improve stratification of patients who may or may not benefit from invasive management.

Abstract
Abstract
Background
Out-of-hospital cardiac arrest (OHCA) is a major cause of death in Europe and the United States. There has been recent literature to suggest that the centralisation of OHCA services may benefit patient outcomes. In 2015, two major tertiary cardiac centres in the UK agglomerated to form a large dedicated tertiary cardiac centre. The previous centre had strict criteria on which OHCA patients could be admitted, with the vast majority of cases being STEMI-related. After the agglomeration, admission criteria were relaxed to include all OHCA cases within geographic range with a suspected cardiac cause.
Purpose
This study aimed to compare the short-term mortality of patients admitted with an OHCA to a tertiary cardiac centre before-and-after a major agglomeration of services had taken place and admission criteria had been relaxed.
Methods
We retrospectively analysed the data of patients admitted before and after agglomeration (2015) with OHCA who were resuscitated via conventional cardiopulmonary resuscitation. Baseline demographic characteristics were recorded, along with factors relating to the cardiac arrest. Primary endpoint was in-hospital mortality.
Results
A total of 650 patients (189 before and 461 after the agglomeration) with an OHCA between 2013 and 2018 were analysed. Patients admitted pre merger were older (67.7 vs 62.4 years, p=0.022), otherwise there were similar baseline demographic characteristics between patients admitted before and after the agglomeration (pre vs post) in terms of gender (74.4% vs 75.9% male, p=0.827), ethnicity (66.7% vs 58.9% Caucasian, p=0.588) and existing coronary artery disease (22.8% vs 22.7%, p=0.432). There were also similar peri-arrest characteristics, with a comparable number of patients having a non-shockable rhythm (15.4% vs 25.4%, p=0.164) and similar total downtimes between the groups (33 vs 32.3 mins, p=0.883). Interestingly there was a decrease in those with cardiogenic shock on arrival (92.3% vs 57.0%, p=0.0001) and fewer patients with an ejection fraction <30% (63.2 vs 38.7%, p=0.0003) post-agglomeration.
There was a greater proportion of non-ACS-related OHCA admission after the agglomeration (16.9% vs 24.1%, p=0.047) and a corresponding decrease in those admitted with a STEMI (81.5% vs 62.3%, p=0.032) and those treated with PCI (77.8% vs 54.0%, p=0.034). Despite this, in-hospital mortality was lower after the agglomeration (69.7% vs 47.1%, p=0.019), which persisted after adjustment for the previously described demographic and arrest-related characteristics using stepwise logistic regression (p=0.036) between the two groups.
Conclusion
Despite an increase in non-ACS-related-OHCA cases, the formation of a centralised invasive heart centre was associated with improved survival in OHCA patients. This suggests there may be a benefit for an out-of-hospital cardiac arrest-centre model of care, supporting a centralised strategy for immediate post-resuscitation care in OHCA patients.

Abstract
Vacuum-packaged Certified Angus Beef (CAB) subprimals ( = 72) that included the longissimus thoracis (LT), longissimus lumborum (LL), gluteus medius (GM), and infraspinatus (IF) muscles were purchased from a major beef packing facility. Subprimals were allocated to 1 of 3 aging periods (14, 28, or 42 d) and aged at 2°C. After aging, 5 steaks were cut from each subprimal and assigned to pH, water-holding capacity, Warner-Bratzler shear force (WBSF), cooked color, cooking yield, cooking loss, and sensory panel analysis. Infraspinatus steaks were more tender ( < 0.05) than all other steaks, and subprimals aged 14 d had greater ( < 0.05) WBSF values than the other 2 aging periods, regardless of muscle. Water-holding capacity and cook yield were greater ( < 0.05) for LL and LT than IF and GM steaks, whereas purge loss was greater ( < 0.05) for IF and GM than LL and LT steaks. Throughout the aging periods, pH declined for all muscle groups, with IF steaks having the greatest ( < 0.05) pH values among all muscles. Among IF steaks, sensory evaluations of all attributes did not ( ≥ 0.26) differ across aging periods; yet among LT steaks, consumers rated those aged 14 d greater ( < 0.05) in overall impression than LT steaks aged 28 and 42 d. Among LT steaks, those aged 14 d received greater ( < 0.05) flavor ratings than LT steaks subjected to longer aging periods, and LT steaks aged 14 d received the greatest ( < 0.05) overall impression, with consumers giving greater ( < 0.05) overall impression scores to LT steaks aged 42 d over those aged 28 d. Aging period had no effect ( ≥ 0.017) on consumer ratings for flavor, tenderness, juiciness, or overall impression of LL steaks. Among GM steaks, consumers rated steaks aged 14 and 28 d more ( < 0.05) flavorful than those aged 42 d, and consumer ratings for overall impression were greater ( < 0.05) for GM steaks aged 28 d than for GM steaks aged 42 d; however, consumers failed ( = 0.035) to note differences in tenderness scores of GM steaks in response to aging period. Furthermore, consumers indicated a greater ( < 0.05) likelihood to purchase LT steaks aged 14 d over LT steaks aged 28 d, LL steaks aged 42 d over LL steaks aged 14 d, and GM steaks aged 14 and 28 d over GM steaks aged 42 d. These results indicate that consumers struggled to identify steak flavor attributes and suggest that the benefit of aging for premium beef products does not offer a tremendous sensory advantage to the consumer.

Abstract
In 1994, it was estimated that about 44,500 American women would die from breast cancer and 7000 women from cervical cancer. While early detection methods (screening mammography, breast examinations, and pap smears) have proven to be effective means of decreasing these cancers, they are underused by all groups. In particular, low-income women use them least, resulting in their lower survival and higher mortality rates than the rest of the population. This article quantifies the effect of a simple intervention undertaken by a health maintenance organization (HMO) serving the indigent to improve breast and cervical cancer screening rates. The HMO mailed personal letters and newsletter articles to women members > or = 40 years about the need for cancer prevention. Articles also were printed in the monthly HMO newsletters to providers about the benefits of using these early detection methods. A review of provider claims from 574 women showed that baseline utilization rates for screening mammograms and pap smears before the intervention in year 1 (1990) were 14% and 16.4%, respectively. After the intervention, in years 2 and 3, mammograms had increased to 41% and pap smears to 38% for both years, indicating a levelling off effect of the intervention by year 3. These data show that while a significant improvement in screening behaviors was achieved, the intervention impact was limited to only about one third of the sample on the long term. Further, data do not indicate whether behavioral change was initiated as the member or provider level. More research is needed to increase overall screening behavior among the indigent and their physicians. The results reported here provide a baseline against which more intensive interventions can be measured in this setting.

Abstract
Recent animal data suggest that the gut plays a far more important metabolic role than previously thought. During critical illness, disruption in bowel barrier function may result in a chronic hypermetabolic state and contribute to multiorgan failure. Animal studies have demonstrated that enterocytes of the gastrointestinal tract use glutamine as a respiratory fuel and during critical illness the consumption of glutamine by the gut significantly increases. The selective uptake of glutamine by the gut, to date, has not been confirmed in humans. Seven patients who sustained multisystem trauma necessitating laparotomy underwent portal venous catheterization. This was done by carefully reopening the obliterated umbilical vein and facilitating access to the left branch of the portal vein using a standard central venous catheter. Portal venous and systemic blood samples were recorded for 5 days after operation. Amino acid levels in both circulations were recorded at 48 h and 5 days. Using Student's t test for related samples, the differences between individual amino acids in portal and systemic circulations were compared. At 48 h, mean(s.d.) portal venous glutamine was 85(5) per cent of the systemic levels (253(80) compared with 296(90) mumol/ml, P less than 0.002). At 5 days, portal glutamine was 87(3) per cent of the systemic levels (255(69) compared with 292(83) mumol/ml, P less than 0.003). Levels of citrulline, a breakdown product of glutamine metabolism, were elevated in the portal venous circulation at 48 h (20(4) compared with 16(3) mumol/ml, P less than 0.005) and at 5 days (21(5) compared with 14(3) mumol/ml, P less than 0.002). No significant differences between any of the other amino acids analysed were identified. This study confirms, for the first time in humans, that selective uptake of glutamine occurs in the gut. In stressed states, glutamine deficiency is associated with gut mucosal atrophy. This has significant implications as glutamine is not provided in most commercially available parenteral and enteral nutrition formulations.

Abstract
Meeting the increased metabolic demands in the critically injured is a continuing challenge. Benefits of early enteral feeding after abdominal trauma have been previously reported, but the frequency of patient intolerance due to GI complaints remains unclear. One hundred twenty-three patients undergoing emergent laparotomy for major abdominal trauma with an abdominal trauma index greater than or equal to 15 were prospectively randomized to either a control group (n = 52, no enteral nutrition during the first 5 days) or an enteral-fed group (n = 71). The enteral group had a needle catheter jejunostomy (NCJ) placed at laparotomy and an elemental diet begun 12 h postoperatively, advanced in volume and concentration at 8-h intervals to 100-125 ml/h of full-strength diet. Symptoms of GI complaints (nausea, vomiting, cramping, distention, and diarrhea) were monitored daily and graded as minimal, moderate, or significant. Fifty percent of the control group had one or more GI complaints during the study period; six (12%) developed moderate discomfort. In the enteral group, 59 (83%) patients reported some GI discomfort; 11 had significant complaints (two nausea, seven cramping, six distention, two diarrhea). Nine (13%) of the enteral-fed patients ultimately required total parenteral nutrition supplementation due to GI complaints. The remaining 62 (87%) enteral patients were maintained on the elemental diet for a mean of 7 days (range 5 to 20). By postoperative day 5, patients received an average of 35 kcal/kg and 14.5 g N/day; 66% (41/62) were in positive N balance.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Recent animal models suggest that enteral feeding (TEN) compared to parenteral nutrition (TPN) improves resistance to infection. This prospective clinical trial examined the impact of early TEN vs. TPN in the critically injured. Seventy-five patients with an abdominal trauma index (ATI) greater than 15 and less than 40 were randomized at initial laparotomy to receive either TEN (Vivonex TEN) or TPN (Freamine HBC 6.9% and Trophamine 6%); both regimens contained 2.5% fat, 33% branched chain amino acids, and had a calorie to nitrogen ratio of 150:1. TEN was delivered via a needle catheter jejunostomy. Nutritional support was initiated within 12 hours postoperatively in both groups, and infused at a rate sufficient to render the patients in positive nitrogen balance. The study groups (TEN = 29 vs TPN = 30) were comparable in age, injury severity and initial metabolic stress. Jejunal feeding was tolerated unconditionally in 25 (86%) of the TEN group. Nitrogen balance remained equivalent throughout the study period, at day 5 TEN = -0.3 +/- 1.0 vs. TPN 0.1 +/- 0.8 gm/day. Traditional nutritional protein markers (albumin, transferrin, and retinol binding protein) were restored better in the TEN group. Infections developed in 5 (17%) of the TEN patients compared to 11 (37%) of the TPN group. The incidence of major septic morbidity was 3% (1 = abdominal abscess) in the TEN group contrasted to 20% (2 = abdominal abscess, 6 = pneumonia) with TPN. This clinical study demonstrates that TEN is well tolerated in the severely injured, and that early feeding via the gut reduces septic complications in the stressed patient.

Abstract
Reprioritization of hepatic protein synthesis, a process involving accelerated production of acute-phase proteins at the expense of constitutive proteins, accompanies major trauma. The impact of isocaloric, isonitrogenous total enteral nutrition (TEN) versus total parenteral nutrition (TPN) on hepatic reprioritization was investigated in a prospective, randomized trial. Of the 59 patients with an abdominal trauma index (ATI) greater than 15 but not more than 40, 45 evaluable patients were followed. Results from 36 (18 TEN, 18 TPN) evaluable patients revealed that mean serum levels of acute-phase proteins increased, whereas mean serum levels increased to a greater extent in the TPN group. The maximal increase from baseline for the acute-phase response in both groups occurred at postinjury day 5 and was significantly higher for alpha 1-antitrypsin (alpha 1AT, p = 0.03) and orosomucoid (p = 0.02) in the TPN group. Nonacute-phase proteins reached a nadir at day 10 in the TPN group and increased in the TEN group; significant differences between TEN and TPN groups appeared for albumin (p = 0.004) and retinol-binding protein (RBP, p = 0.03); alpha 2-macroglobulin (alpha 2M) approached significance at day 10 (p = 0.07). When change from baseline values was compared, day 10 increases in alpha 2M were significantly higher (p = 0.04) in the TEN group. These data suggest that postinjury TEN attenuates reprioritization of hepatic protein synthesis in patients sustaining major trauma.

Abstract
Benefits of immediate postinjury nutritional support remain ill defined. Seventy-five consecutive patients undergoing emergent celiotomy with an abdominal trauma index (A.T.I.) greater than 15 were randomized prospectively to a control group (no supplemental nutrition during first 5 days) or enteral-fed group. The enteral patients had a needle catheter jejunostomy (N.C.J.) placed at laparotomy with the constant infusion of an elemental diet (Vivonex HN) begun at 18 hours and advanced to 3,000 ml/day (3,000 kcal, 20 gm N2) within 72 hours. Control and enteral-fed groups were comparable with respect to demographic features, trauma mechanism, shock, colon injury, splenectomy, A.T.I., and initial nutritional assessment. Twenty (63%) of the enteral patients were maintained on the elemental diet greater than 5 days; four (12%) needed total parenteral nutrition (T.P.N.). Nine (29%) of the control patients required T.P.N. Nitrogen balance was markedly improved (p less than 0.001) in the enteral-fed group. Although visceral protein markers and overall complication rate were not significantly different, septic morbidity was greater (p less than 0.025) in the control group (abdominal infection in seven and pneumonia in two) compared to the enteral-fed patients (abdominal abscess in three). Analysis of patients with A.T.I. 15-40 disclosed sepsis in seven (26%) of the control versus one (4%) of the enteral-fed group (p less than 0.01). Our clinical experience demonstrates the feasibility of immediate postoperative enteral feeding via N.C.J. after major abdominal trauma, and suggests this early nutrition reduces septic complications in critically injured patients.

Abstract
Twenty-one patients with multiple organ failure were studied with hemodynamic monitoring. The five survivors were compared with the 16 nonsurvivors. Significant differences were found in the cardiac index (CI), the left ventricular stroke work index (LVSWI), and the pulmonary vascular resistance index (PVRI). The CI was higher in survivors (4.38 +/- 1.71) than in nonsurvivors (3.43 +/- 1.49). The LVSWI was also higher (43.0 +/- 16.8, 28.7 +/- 12.8) than in nonsurvivors (47.4 +/- 2.91). The PVRI was lower in survivors (168 +/- 122) than in nonsurvivors (474 +/- 291). It is postulated that the elevated PVRI in MOF is related to the adult respiratory distress syndrome.

Abstract
Previous work has shown that an abdominal trauma index (ATI) based on anatomic severity of injury reliably predicts complications following abdominal trauma, whereas the Prognostic Nutritional Index (PNI) does not. This study was undertaken to reconcile the disparity between the PNI and ATI as predictors of postoperative morbidity and mortality. Twenty-four patients undergoing immediate laparotomy following acute abdominal trauma were evaluated. Their mean age was 32.8 years (range 18-59 years); 18 were men. All patients underwent nutritional assessment within 12 hours of surgery. A statistical comparison of blood replacement, operating time, ATI, and PNI was performed. The mean PNI was 51 and mean blood replacement was 12.5 units. Using linear regression the PNI and amount of blood replacement correlated significantly (r = 0..44, p less than 0.05). Operating time and ATI did not correlate with PNI. In conclusion, the PNI was more strongly influenced by blood loss than severity of intraperitoneal injury. For this reason it is relatively ineffective in predicting complications following trauma.

Abstract
The safety and efficacy of enteral feeding by needle catheter jejunostomy has prompted its use after many major gastrointestinal operations. Indeed, the technical complications of this procedure are infrequent. This report details the development of massive pneumatosis intestinalis associated with elemental feeding via jejunostomy. The proposed etiology includes excessive gas accumulation within the small intestine secondary to 1) inadequate nasogastric suction, 2) post-traumatic intestinal ileus, and 3) disaccharide fermentation; combined with a mucosal defect created by the catheter jejunostomy. Successful management consists of nasogastric suction and immediate termination of the enteral feeding.

Abstract
The high nitrogen demands imposed by severe trauma may quickly render the injured patient malnourished. Nutritional assessment of these patients is confused by tissue damage, shock, blood loss, operation, and anesthesia. Consequently, standard nutritional markers do not correlate well with immunocompetence and postoperative morbidity. For this reason we devised an abdominal trauma index (ATI) based on the anatomical severity of injury. The ATI is calculated by assigning a risk factor (1-5) to each organ injured and then multiplying this by a severity-of-injury estimate (1-5). The sum of the individual organ scores comprises the final ATI. The incidence of postlaparotomy complications is low (5%) with an ATI less than 15, intermediate (15%) with 15-25, and high (50%) with greater than 25. Having identified the high-risk trauma patient, we initiated a prospective randomized study to assess the cost-benefit of early nutritional support. Patients with an ATI greater than 15 were allocated to a control group (no supplemental nutrition during first five postoperative days) or enteral-fed group. The enteral group had a needle catheter jejunostomy (NCJ) placed at laparotomy. The constant infusion of an elemental diet (Vivonex HN) was begun at 18 hours postoperatively and advanced to 3,000 cc/day within 72 hours. To date 26 patients (14 control, 12 enteral) have been entered in this study. At one week, nitrogen balance in the control group (-12.9 to -11.1 g/day) continues to be negative compared to a positive trend (-12.2 to +3.3 g/day) in the fed group. In control patients serum albumin (3.54 +/- 0.16 to 3.19 +/- 0.15 g%) and transferrin (227 +/- 11 to 204 +/- 10 mg%) decrease while in the enteral patients albumin (3.27 +/- 0.11 to 3.34 +/- 0.15 g%) and transferrin (229 +/- 10 to 234 +/- 12 mg%) remain stable. Although the incidence of overall morbidity is similar, septic complications occurred in 29% (4/14) of the control group compared to none in the enteral group. Our experience suggests the following: (1) Anatomical severity of injury is a better predictor of postinjury septic morbidity than standard nutritional markers; (2) immediate postoperative feeding by NCJ is safe and feasible; and (3) early nutritional support decreases the incidence of septic complications in the severely injured patient.

Abstract
Jejunostomy feedings were used in the immediate postoperative period in patients with massive abdominal and retroperitoneal injuries. Patients were selected for early feeding if they had two or more major visceral injuries. Over a six-month period, 30 such patients were studied: ten had blunt trauma, 11 had gunshot wounds, and nine had stab injuries. The injuries included 11 pancreatic, ten small-bowel, six colon, and six major retroperitoneal vascular injuries. A 16-gauge intracatheter was placed in the proximal jejunum. The constant infusion of nutritional solution (Vivonex HN) was begun 18 hours postoperatively, and within 72 hours all patients were receiving 2,400 calories per day. Feedings were maintained for an average of eight days. Serum albumin and transferrin levels, total lymphocyte count, and delayed hypersensitivity were maintained or improved during jejunal feeding. Patients with pancreatic injuries received supplemental nutrition without evidence of pancreatic stimulation. Needle-catheter jejunostomy can provide early, safe nutritional support after major abdominal trauma. Further investigation is needed to determine who will benefit from this early feeding.

Abstract
This experiment was designed to compare the monitoring performance of Ss using a visual display with the performance of Ss using an auditory display. 24 Ss were randomly assigned to monitor either the visual or the auditory display for a 3-hr. period. Two measures of performance, reaction time and probability of responding, were obtained during the monitoring session. An analysis of the results indicates that Ss who monitored the auditory display had shorter reaction times, higher probability of responding, and less variability than Ss who monitored the visual display.
