[Artículo traducido] Mortalidad a 30 días en pacientes con fractura de fémur proximal durante la pandemia COVID-19 en Vizcaya (País Vasco)

OBJECTIVES

Compare 30-day mortality rate following a proximal femur fracture (PFF) and SARS-CoV-2 infection versus a PFF and no SARS-CoV-2 infection.

DESIGN

Retrospective comparative study.

SETTING

Three university hospitals in Biscay province (Basque Country, Spain).

PATIENTS

77 patients over 65 years-old with PFF (AO 31-A and 31-B).

INTERVENTION

Study conducted between 9 March and 15 April 2020. The COVID-19 group included only patients with SARS-CoV-2 infection, confirmed by a positive RT-PCR test.

MAIN OUTCOME MEASUREMENTS

30-Day mortality rate and risk factors for mortality.

RESULTS

Of a total 77 patients, 10 were diagnosed with SARS-CoV-2 infection. Mean age was 85 years. Patients with SARS-CoV-2 infection had higher BMI (29.53 kg/m²) compared to patients without infection (24.09 kg/m²) (p = 0.001). No significant differences were found between both groups in terms of the Charlson Comorbidity Index, ASA score, use of oral anticoagulants or presence of cognitive impairment. Seven of the 10 patients in the COVID-19 group developed (viral) pneumonia, as compared to one single case (1/67) of (bacterial) pneumonia in the control group (p < 0.001). Thirty-days mortality was higher (p = 0.03) in COVID-19 patients (40%) than in those in the control group (11.9%). In the multivariate analysis, age ≥ 91 years-old, ASA class IV and BMI > 25 kg/m² were significant predictors of 30-day mortality. All deaths in the COVID-19 group occurred while the patients were hospitalized.

CONCLUSIONS

SARS-CoV-2 infection in patients with a PFF was seen to result in higher rates of early mortality, with COVID-19-related pneumonia being the leading direct cause of mortality.

LEVEL OF EVIDENCE

Level III study.

[Risk factors for clinical deterioration in patients admitted for COVID-19: A case-control study]

INTRODUCTION

There is controversy regarding the best predictors of clinical deterioration in COVID-19.

OBJECTIVE

This work aims to identify predictors of risk factors for deterioration in patients hospitalized due to COVID-19.

METHODS DESIGN

Nested case-control study within a cohort. Setting: 13 acute care centers of the Osakidetza-Basque Health Service. Participants: Patients hospitalized for COVID-19 with clinical deterioration-defined as onset of severe ARDS, ICU admission, or death-were considered cases. Two controls were matched to each case based on age. Sociodemographic data; comorbidities; baseline treatment; symptoms; date of onset; previous consultations; and clinical, analytical, and radiological variables were collected. An explanatory model of clinical deterioration was created by means of conditional logistic regression.

RESULTS

A total of 99 cases and 198 controls were included. According to the logistic regression analysis, the independent variables associated with clinical deterioration were: emergency department O2 saturation ≤90% (OR 16.6; 95%CI 4-68), pathological chest X-ray (OR 5.6; 95%CI 1.7-18.4), CRP >100 mg/dL (OR 3.62; 95%CI 1.62-8), thrombocytopenia with < 150,000 platelets (OR 4; 95%CI 1.84-8.6); and a medical history of acute myocardial infarction (OR 15.7; 95%CI, 3.29-75.09), COPD (OR 3.05; 95%CI 1.43-6.5), or HT (OR 2.21; 95%CI 1.11-4.4). The model's AUC was 0.86. On the univariate analysis, female sex and presence of dry cough and sore throat were associated with better clinical progress, but were not found to be significant on the multivariate analysis.

CONCLUSION

The variables identified could be useful in clinical practice for the detection of patients at high risk of poor outcomes.

P994Association of late gadolinium enhancement with prognosis and sudden cardiac death risk in non-ischemic dilated cardiomyopathy

Objectives

to evaluate the association between late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging (cMRI) and prognosis in patients with non-ischemic dilated cardiomyopathy (NIDM).

Background

Risk stratification in NIDM needs to be improved.

Methods

A total of 210 patients with NIDM and cMRI from 2005 to 2018 were included in our population. Outcomes were retrospectively assessed by medical records. The pattern of LGE was classified as midwall, subepicardial, or both patterns. Primary endpoint was sudden cardiac death (SCD) and aborted SCD. Secondary endpoints were global mortality and a composite endpoint of cardiovascular mortality and heart failure hospitalization. Demographic and clinical parameters were also evaluated. Patients with LGE (LGE+) were more likely to be male (80,6% vs 66,7%, p=0,03). No significant differences were observed between LGE+ and LGE− patients in comorbidities, NYHA class, left ventricular ejection fraction (LVEF), left bundle branch block or neurohormonal treatment.

Results

Of 210 patients (71,4% men, median age 59,8 years) with a median follow up of 5,6 years (3,24–8,15), 72 patients (34,3%) had non ischemic LGE (LGE+). Mean LVEF was 34%.

SCD or aborted SCD occurred in 11 patients (5,2%). 6 patients (9,5%) with LGE+ reached the primary endpoint vs 5 (4,07%) of LGE− patients (p=0,19).

The adjusted OR for the presence of LGE in the composite endpoint (cardiovascular mortality and heart failure hospitalization) was 2,45, confidence interval (CI): 1,16–5,17, (p=0,02).

LGE presence was not associated with global mortality.

The subepicardial pattern of LGE was associated with SCD and aborted SCD: 3 out of 11 patients (27, 1%) with subepicardial pattern of LGE suffered from SCD or aborted SCD (p=0,02).

Conclusions

In our cohort of 210 patients with NIDM, LGE presence was not associated with SCD and aborted SCD, probably because of low event rate in a relatively small population. However, LGE presence was associated with the composite endpoint of cardiovascular mortality and heart failure hospitalization. The subepicardial pattern of LGE identified patients at high risk of SCD and aborted SCD.

Prognostic factors after a traumatic hip dislocation. A long-term retrospective study

INTRODUCTION

Traumatic hip dislocations can have devastating complications such as osteoarthritis or osteonecrosis. The aim of this study was to identify the variables and prognostic factors associated with clinical and radiological outcome after a traumatic hip dislocation at long-term follow-up.

MATERIAL AND METHODS

A review was performed of all dislocations and fracture-dislocations of the hip from January 1999 to December 2012. A computed tomography scan was performed after reduction in all cases. The Harris Hip Score and modified Merle-d'Aubigné-Postel method were used for clinical evaluation and radiological assessment was performed according to the Thompson and Epstein classification.

RESULTS

There were 30 cases in 29 patients with a mean follow-up of 11 years (range, 4-17). The great majority were simple dislocations (21; 70%) vs. complex dislocations (9; 30%). Closed reduction was performed in less than 6h in all except one case (29; 96.7%). All of the patients with simple dislocations had an excellent outcome without radiological signs of osteoarthritis at the end of the follow-up (P<.01). Overall, arthritic signs had developed in 4 patients (13.3%) and avascular necrosis was noted in 3 patients (10%). Five patients with intraarticular fragments were treated non-operatively, and 3 of them developed arthritic changes (P<.05).

CONCLUSION

Our study suggests that complex dislocations are associated with poorer functional and radiological outcomes than simple dislocations. We also found a strong association between intraarticular fragments and osteoarthritis, so surgical fragment removal could be considered in these cases.

Analgesia with interfascial continuous wound infiltration after laparoscopic colon surgery: A randomized clinical trial

OBJECTIVES

For major laparoscopic surgery, as with open surgery, a multimodal analgesia plan can help to control postoperative pain. Placing a wound catheter intraoperatively following colon surgery could optimize the control of acute pain with less consumption of opioids and few adverse effects.

METHODS

We conducted a prospective, randomized, study of patients scheduled to undergo laparoscopic colon surgery for cancer in Galdakao-Usansolo Hospital from January 2012 to January 2013. Patients were recruited and randomly allocated to wound catheter placement plus standard postoperative analgesia or standard postoperative analgesia alone. A physician from the acute pain management unit monitored all patients for pain at multiple points over the first 48 hours after surgery. The primary outcome variables were verbal numeric pain scale scores and amount of intravenous morphine used via patient controlled infusion.

RESULTS

92 patients were included in the study, 43 had a wound catheter implanted and 49 did not. Statistically significant differences in morphine consumption were observed between groups throughout the course of the treatment period. The mean total morphine consumption at the end of the study was 5.63±5.02mg among wound catheter patients and 21. 86±17.88mg among control patients (P=.0001). Wound catheter patients had lower pain scale scores than control patients throughout the observation period. No adverse effects associated with the wound catheter technique were observed. The wound catheter group showed lower hospital stays with statistically significant difference (P=.02).

CONCLUSIONS

In patients undergoing laparoscopic colon surgery, continuous infusion of local anaesthetics through interfascial wound catheters during the first 48h aftersurgery reduced the level of perceived pain and also reduced parenteral morphine consumption with no associated adverse effects and lower hospital stays.

Cauda equina syndrome secondary to lumbar disc herniation: Surgical delay and its relationship with prognosis

OBJECTIVE

To determine whether surgical treatment delayed for more than 48 hours in patients with cauda equina syndrome (CES) influenced the clinical outcome.

MATERIAL AND METHODS

A retrospective study of 18 patients treated in our hospital from March 2000 to January 2012, after presenting with CES. The pre- and post-operative clinical status was determined: existence of back pain and/or sciatica, sensory disturbance in the perineum, sensory and motor deficits in the lower extremities, and the degree of sphincter incontinence (complete or incomplete CES). A clinical assessment was performed using the Oswestry disability index.

RESULTS

As regards the onset of symptoms, 44% (8 of 18) of patients were treated at an early stage (within 48 hours). None of the patients with complete CES operated in the early stage had urinary incontinence, and also had greater motor recovery. Of the 5 patients with complete CES who underwent delayed surgery, 3 showed residual urinary incontinence. A mean of 12.55 was obtained on the Oswestry disability index scale at the end of follow-up.

CONCLUSION

Although no statistically significant difference was found in our study, we observed greater motor and sphincter recovery in patients who were operated on within 48 hours.

Changes in health-related quality of life and activities of daily living after hip fracture because of a fall in elderly patients: a prospective cohort study

BACKGROUND

The impact of hip fracture because of a fall on health-related quality of life (HRQoL) and activities of daily living (ADL) have not been well established.

AIM

To evaluate changes in HRQoL and the ability to conduct ADL among patients with hip fracture because of a fall and to compare these changes with patients who did not fall and break a hip, adjusting by gender and age.

METHODS

Adults aged 65 or more who attended the emergency departments of seven public hospitals were recruited in a prospective double-cohort study (fracture cohort, n = 776; non-fracture cohort, n = 115). ADL and HRQoL were assessed at baseline (during the postfall hospitalisation or by telephone afterwards) and 6 months later using the Barthel Index and the Lawton Brody Index for ADL, and the Short Form Health Survey (SF-12) and Western Ontario and McMaster Universities Osteoarthritis Index short form (WOMAC-SF) for HRQoL.

RESULTS

Adjusting by gender, age and baseline status, a hip fracture was a strong predictor of decline in all outcomes measured except for mental quality of life among men (measured by SF-12). Hip fracture patients younger than 74 years reported significantly more pain (measured by WOMAC-SF) than the comparison group (p = 0.02), but this difference was not observed among older patients (p = 0.19 for 75-84 years; p = 0.39 for ≥ 85 years).

DISCUSSION

Hip fractures have profound effects on HRQoL and ADL in both men and women, regardless of age. This indicates the need for special follow-up care of elderly hip fracture patients in the immediate and late postfracture periods.

Health-related quality of life and functionality in elderly men and women before and after a fall-related wrist fracture

AIMS

To evaluate health-related quality of life (HRQoL) and functionality among older men and women who suffered a wrist fracture because of a fall and to identify postfracture consequences.

METHODS

Observational, prospective cohort study of patients recruited in the emergency departments (ED) of six public hospitals of the Basque Health Service and one of the Catalan Health Service. Two groups of adults aged 65 or older were recruited: 960 with wrist fractures because of falls (fracture cohort) and 119 without fall-related wrist fractures in the previous year (non-fracture cohort). We collected sociodemographical and clinical data; general and specific HRQoL data measured by the 12-Item Short Form Health Survey (SF-12) and a short version of the Disabilities of the Arm, Shoulder, and Hand instrument (QuickDASH); and data about basic (BADL) and instrumental (IADL) activities of daily living, measured by the Barthel Index and the Lawton and Brody Index (LBI).

RESULTS

Women with wrist fractures exhibited greater declines than men 6 months after the fall in all questionnaires except the LBI, and greater declines than those in the non-fracture cohort independent of gender. Patients aged 80 years and older presented with worse baseline scores in all the outcome measures and lost more HRQoL and functionality after wrist fractures.

DISCUSSION

Women and older individuals experienced the greatest reductions in HRQoL and functionality after a fall-related wrist facture, suggesting that they might merit special attention in clinical care and public health policy.

CONCLUSIONS

Specific prevention strategies may be needed to avoid or reduce the consequences of fall-related wrist fractures.

Impact of interdisciplinary treatment on physical and psychosocial parameters in patients with fibromyalgia: results of a randomised trial

AIM

Fibromyalgia (FM) is a persistent disorder that can have a devastating effect on patients' lives. The purpose of the study was to assess the effects of an interdisciplinary treatment for FM on patients' physical and psychosocial parameters.

METHODS

A randomised controlled clinical trial carried out among 153 patients. The control group (CG) received standard pharmacological therapy. The experimental group (EG) received an interdisciplinary treatment. At baseline and 6 months after the intervention, participants completed assessment for impact of FM in the quality of life, anxiety, depression, coping with pain, social support and satisfaction with the treatment.

RESULTS

A total of 110 participants completed the trial. Six months after the intervention, statistically significant improvements in quality of life (p = 0.04), pain (p = 0.03), self-assertiveness (p = 0.01), mental self-control (p = 0.05), social support (p = 0.02) and satisfaction (p = 0.0001) were observed in the EG. Randomisation to the EG was identified as a predictor for improvement.

CONCLUSION

An interdisciplinary intervention may be appropriate for patients referred to a hospital pain management unit.

Acute adverse reactions to iopromide vs iomeprol: a retrospective analysis of spontaneous reporting from a radiology department

OBJECTIVE

To compare the safety of iopromide and iomeprol use in a hospital that switched from the former to the latter and found an apparent increase in the number (and a different profile) of adverse reactions reported for iomeprol, putting the safety of its use into question.

METHODS

This was a retrospective study of cases of acute reactions to iopromide and iomeprol reported in two successive time periods. Data from examinations using iopromide (62539 CT scans and 10348 urography scans) and iomeprol (34308 CT scans and 2846 urography scans) were obtained from the computer system of the hospital.

RESULTS

For each period, 154 cases of reactions were reported for iopromide and 86 for iomeprol, being severe in 10 (6.5%) patients for iopromide vs 17 (19.8%) patients for iomeprol; a statistically significant difference of p<0.003 was recorded. The most frequent adverse reactions (%/%) for iopromide/iomeprol were urticaria (29.1/17.2), pruritus (22.6/15.6), upper respiratory tract signs and symptoms (12.1/16.7), oedema (4.3/0), erythemas (3.4/5.0), nausea or vomiting (1.2/11.7) and chest pain (0/3.9) (p<0.0001 for the global comparison). The distribution of the reactions (%/%) by System Organ Class for iopromide/iomeprol was skin (56.7/41.1), respiratory (19.2/26.7), vascular (6.8/2.2), general (5.3/7.2), gastrointestinal (4.6/15.0) and others (7.4/7.9) (p<0.0002 for the global comparison).

CONCLUSION

Adverse reactions were more severe for iomeprol. Skin and vascular reactions with no chest pain were more frequent for iopromide, whereas gastrointestinal reactions were more frequent for iomeprol.

ADVANCES IN KNOWLEDGE

Comparative studies of media contrast safety are scarce and summary information on product characteristics is insufficient. This study showed the differences in severity and profile of adverse reactions between iopromide and iomeprol.

Evaluation of the psychometric characteristics of the Spanish version of the Anorectic Behaviour Observation Scale

AIMS

The Anorectic Behaviour Observation Scale (ABOS) was designed to obtain information from relatives about behaviours and attitudes of patients with eating disorders (ED). The aim of this study was to validate the ABOS into Spanish.

METHODS

We evaluated the psychometric characteristics of the Spanish version of the ABOS in a clinical ED sample (239 caregivers of 143 ED patients). Instrument reliability (internal consistency), validity (construct, convergent and discriminant, known groups), responsiveness and goodness-of-fit were measured.

RESULTS

Data from the Spanish population revealed a three-factor structure similar to that of the original ABOS, although the composition of subscales differed somewhat from the original. An ABOS cut-point of 21 was identified. The Cronbach's alpha coefficient for the total ABOS score was 0.81. Correlations with other instruments demonstrated convergent and divergent validity. Among caregivers, the total ABOS score and Factor scores significantly discriminated between anxiety, depression and health-related quality of life, while among ED patients they discriminated between diagnosis, severity and level of ED symptoms - evidence of known-groups validity.

CONCLUSION

These findings suggest that the ABOS can be reliably and validly used in Spain in a number of different clinical contexts, by researchers and clinicians alike.

Relationship of sociodemographic variables with outcomes after cataract surgery

PURPOSE

The objective of this study is to analyse the relationship between sociodemographic characteristics of patients undergoing cataract extraction and their outcomes.

METHODS

The method comprised a prospective cohort study of patients recruited from 17 hospitals of different areas of Spain. Data gathered before surgery included sociodemographic variables, visual acuity, and visual function (using the Visual Function Index-14). After surgery, we assessed visual acuity and visual function at 6 weeks and at 3 months, respectively. Multivariate multilevel analysis was performed to assess the relationship of sociodemographic variables with changes in visual acuity and function, analysing whether improvements surpassed the minimal clinically important differences (MCIDs).

RESULTS

Multivariate analysis showed that for visual acuity, (i) older men had a lower odds ratio (OR) of surpassing the MCID (OR: 65-75 years, 0.64; >75 years, 0.51); (ii) those with primary (1.65) or secondary (1.41) education had higher ORs than those with no formal education; and (iii) those living in a residential home had a lower OR than men living alone (0.36). In women, we found that the higher the educational level, the greater the improvement in visual acuity (primary, 1.41; secondary, 1.76), whereas socially dependent women (0.70) were less likely to exceed the MCID. With regards to predictors related to achievement of an MCID in visual function, only dependency was associated with more improvement in men (OR: 1.39), whereas in women the educational level was the only predictor (primary: 0.72; secondary: 0.61).

CONCLUSIONS

This study found that patients with certain sociodemographic characteristics were less likely to experience an MCID in visual acuity or visual function after cataract surgery.

Explicit criteria for hospital admission in exacerbations of chronic obstructive pulmonary disease

OBJECTIVE

To develop detailed, explicit criteria for determining the appropriateness of admission for patients with exacerbations of chronic obstructive pulmonary disease (COPD).

DESIGN

Using a modified Delphi process, a panel of seven pneumologists and five emergency department (ED) physicians was assembled to establish the appropriateness of hospital admission for 896 distinct theoretical scenarios. To assess the reliability of the criteria, a second national panel of five pneumologists and five ED physicians was assembled. We examined the influence of all variables on the first panel score using linear regression models. The explicit criteria developed were summarised by classification and regression tree analysis.

RESULTS

The appropriateness of the hospitalisation scenarios increased with the severity of COPD. The kappa of agreement between the two panels was 0.79. Predictors of appropriate hospitalisation were severity of current COPD exacerbation, response to previous treatment and expected adherence to treatment. The panel results were synthesised and presented in three decision trees. Misclassification error in the decision trees, as compared with the panel's original ratings, was 6.1%.

CONCLUSIONS

These explicit criteria can be used to help determine the appropriateness of admission for patients with exacerbations of COPD.

[Study of contacts in children and adolescents using the QuantiFERON®-TB Gold In-Tube]

OBJECTIVE

To compare the results of the Mantoux Tuberculin Test (TT) and the QuantiFERON TB® Gold In-Tube (QFT-GIT) in a population of children and adolescents with TB contacts.

MATERIAL AND METHODS

A prospective study using data collected on children and adolescents (< 17years) from a Health District of 300,000 inhabitants in the Basque Country (Spain) recruited into a TB contact study over a period of almost three years. The study included performing the Tuberculin Test using the Mantoux technique (with 2-TU of RT-23 PPD RT23 and Tween 80), and the QFT-GIT simultaneously, and collecting the demographic and clinical data.

RESULTS

Of the 160 children included in the study, 14% had a positive TT (≥ 5mm) and 11% a positive QFT-GIT. There was 95%-96% agreement between the tests, depending on the TT cut-off point chosen, and was higher in non-vaccinated children (100%) and in children less than 5 years-old (100%). A significant relationship was observed between a positive result for both tests with exposure in the home. The use of QFT-GIT in the screening of latent TB infection could reduce preventive treatments by 28%-34% compared with conventional screening with the TT.

CONCLUSIONS

The behaviour of QFT-GIT was comparable to the TT in identifying children with a tuberculosis infection; therefore it could potentially replace the TT.
