[Physical structure, human resources, and health care quality indicators in public hospital emergency departments in the autonomous communities of Madrid and Catalonia: a comparative study]

OBJECTIVES

To compare the general, structural, and organizational characteristics of public hospital emergency departments in the Spanish autonomous communities of Madrid and Catalonia.

MATERIAL AND METHODS

Descriptive survey-based study covering 3 areas of inquiry: general hospital features (18 questions), structural features of the emergency department (14 questions), and organizational and work-related policies of the emergency department (30 questions). Hospitals were grouped according to complexity: local hospitals (level 1), high-technology or referral hospitals (levels 2-3).

RESULTS

We studied 26 hospital departments in Madrid (21, levels 2-3; 5, level 1) and 55 in Catalonia (24, levels 2-3; 31, level 1). Hospitals in Madrid are in newer buildings (P=.002), have more beds on conventional wards and in critical care units (P<.001, both comparisons), are more often affiliated with a university (P<.001), and serve larger populations (P=.027). The emergency departments in Madrid have larger surface areas available for clinical care and more cubicles for preliminary evaluations and observation beds (P=.001, all comparisons). Hospitals in Madrid also attended a larger median number of emergencies (P<.001). More physicians were employed in Catalonia overall, but the numbers of physician- and nurse-hours per hospital were higher in Madrid, where it was more usual for physicians to work exclusively in the emergency department (92.5% in Madrid vs 56.8% in Catalonia, P<.001). However, fewer of the employed physicians had permanent contracts in Madrid (30.5% vs 75.1% in Catalonia, P<.001). The ratio of resident physicians to staff physicians differs between the 2 communities on afternoon/evening, night, and holiday shifts (3:1 in Madrid; 1:1 in Catalonia).

CONCLUSION

The physical and functional structures of hospital emergency departments in the communities of Madrid and Catalonia differ significantly. The differences cannot be attributed exclusively to geographic location.

Ecchymosis and/or haematoma formation after prophylactic administration of subcutaneous enoxaparin in the abdomen or arm of the critically ill patient

INTRODUCTION

Ecchymosis and/or haematoma are the most common adverse events after subcutaneous administration of low molecular weight heparin. There is no strong recommendation as to the puncture site.

OBJECTIVE

To evaluate the adverse events, ecchymosis and/or haematoma after the administration of prophylactic subcutaneous enoxaparin in the abdomen vs the arm in the critically ill patient.

METHODOLOGY

A randomised, two-arm clinical trial (injection in the abdomen vs the arm), performed between July 2014 and January 2017, in an 18-bed, polyvalent intensive care unit. Patients receiving prophylactic enoxaparin, admitted >72h, with no liver or haematological disorders, a body mass index (BMI) >18.5, not pregnant, of legal age and with no skin lesions which would impede assessment were included. We excluded patients who died or who were transferred to another hospital before completing the evaluation. We gathered demographic and clinical variables, and the onset of ecchymosis and/or haematomas at the injection site after 12, 24, 48 and 72hours. A descriptive analysis was undertaken, with group comparison and logistic regression. The study was approved by the ethics committee with the signed consent of patients/families.

RESULTS

301 cases (11 excluded): 149 were injected in the abdomen vs 141 in the arm. There were no significant differences in demographic and clinical variables, BMI, enoxaparin dose or antiplatelet administration [ecchymosis, abdomen vs arm, n(%): 66(44) vs 72(51), P=.25] [haematoma abdomen vs arm, n(%): 9(6) vs 14(10), P=.2]. Statistical significance was found in the size of the haematomas after 72h: [area of haematoma (mm²) abdomen vs arm, median (IQR): 2(1-5.25) vs 20(5.25-156), P=.027].

CONCLUSIONS

In our patient cohort, prophylactic subcutaneous enoxaparin administered in the abdomen causes fewer haematomas after 72hours, than when administered in the arm. The incidence rate of ecchymosis and haematoma was lower than the published incidence in critically ill patients, although patients receiving anti-platelet agents present a higher risk of injury. No relationship was observed in relation to BMI.

Self versus examiner administration of the Ocular Surface Disease Index©

PURPOSE

To compare the difference in Ocular Surface Disease Index^© (OSDI) scores when participants were given the OSDI to complete on their own (self-guided, SG), versus under the guidance of the examiner (examiner-guided, EG).

METHODS

100 participants enrolled in this prospective two-visit study (fifty under-45 years old, 38F/12M; and fifty 45 years-and-older, 42F/8M). Participants who scored ≥1 on the Subjective Evaluation of Symptoms of Dryness (SESoD) were included in this study. Participants completed the OSDI SG during the first visit. Participants returned the next day and repeated the OSDI, but with EG (with standardized instructions). Participants were under deception and believed that they were comparing the OSDI to the SESoD.

RESULTS

The mean OSDI score of the SG and EG administration was 32.0±17.3 and 33.8±19.6 respectively (p>0.05) with 95% limits of agreement between -20.6 and +24.2. The correlation between SG and EG administration was Spearman's r=0.81, p<0.01. The mean difference between SG and EG was not significant (p>0.05) for both the under-45 group, and 45-and-older group. The 95% limits of agreement for the under-45 group were smaller than the 45-and-older group (under-45: [-15.5, +13.1,], 45-and-older: [-23.3, +32.2]). A significant difference was found between 8 of the 12 questions items (all p≤0.01). However, the mean difference for each was <0.6 and was not considered to be clinically significant.

CONCLUSION

There was no clinically significant difference in OSDI score between SG and EG administration, however having instructions provided with EG administration affected variability of scores in the older group more than the younger group.
