Effect of Prehospital Epinephrine on Out-of-Hospital Cardiac Arrest Outcomes: A Propensity Score-Matched Analysis

PurposeA pilot project using epinephrine at the scene under medical control is currently underway in Korea. This study aimed to determine whether prehospital epinephrine administration is associated with improved survival and neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients who received epinephrine during cardiopulmonary resuscitation (CPR) in the emergency department.Materials and MethodsThis retrospective observational study used a nationwide multicenter OHCA registry. Patients were classified into two groups according to whether they received epinephrine at the scene or not. The associations between prehospital epinephrine use and outcomes were assessed using propensity score (PS)-matched analysis. Multivariable logistic regression analysis was performed using PS matching. The same analysis was repeated for the subgroup of patients with non-shockable rhythm.ResultsPS matching was performed for 1084 patients in each group. Survival to discharge was significantly decreased in the patients who received prehospital epinephrine [odds ratio (OR) 0.415, 95% confidence interval (CI) 0.250–0.670, p<0.001]. However, no statistical significance was observed for good neurological outcome (OR 0.548, 95% CI 0.258–1.123, p=0.105). For the patient subgroup with non-shockable rhythm, prehospital epinephrine was also associated with lower survival to discharge (OR 0.514, 95% CI 0.306–0.844, p=0.010), but not with neurological outcome (OR 0.709, 95% CI 0.323–1.529, p=0.382).ConclusionPrehospital epinephrine administration was associated with decreased survival rates in OHCA patients but not statistically associated with neurological outcome in this PS-matched analysis. Further research is required to investigate the reason for the detrimental effect of epinephrine administered at the scene.     

An evaluation of the professional,social and demographic profile and quality of life of physicians working at the Prehospital Emergency Medical System (SAMU) in Brazil

OBJECTIVE:

To describe the profile of physicians working at the Prehospital Emergency Medical System (SAMU) in Brazil and to evaluate their quality of life.

METHODS:

Both a semi-structured questionnaire with 57 questions and the SF-36 questionnaire were sent to research departments within SAMU in the Brazilian state capitals, the Federal District and inland towns in Brazil.

RESULTS:

Of a total of 902 physicians, including 644 (71.4%) males, 533 (59.1%) were between 30 and 45 years of age and 562 (62.4%) worked in a state capital. Regarding education level, 45.1% had graduated less than five years before and only 43% were specialists recognized by the Brazilian Medical Association. Regarding training, 95% did not report any specific training for their work at SAMU. The main weaknesses identified were psychiatric care and surgical emergencies in 57.2 and 42.9% of cases, respectively; traumatic pediatric emergencies, 48.9%; and medical emergencies, 42.9%. As for procedure-related skills, the physicians reported difficulties in pediatric advanced support (62.4%), airway surgical access (45.6%), pericardiocentesis (64.4%) and thoracentesis (29.9%). Difficulties in using an artificial ventilator (43.3%) and in transcutaneous pacing (42.2%) were also reported. Higher percentages of young physicians, aged 25-30 years (26.7 vs 19.0%; p<0.01), worked exclusively in prehospital care (18.0 vs 7.7%; p<0.001), with workloads >48 h per week (12.8 vs 8.6%; p<0.001), and were non-specialists with the shortest length of service (<1 year) at SAMU (30.1 vs 18.2%; p<0.001) who were hired without having to pass public service exams* (i.e., for a temporary job) (61.8 vs 46.2%; p<0.001). Regarding quality of life, the pain domain yielded the worst result among physicians at SAMU.

CONCLUSIONS:

The doctors in this sample were young and within a few years of graduation, and they had no specific training in prehospital emergencies. Deficiencies were mostly found in pediatrics and psychiatry, with specific deficiencies in the handling of essential equipment and in the skills necessary to adequately attend to prehospital emergencies. A disrespectful labor scenario was also found; the evaluation of quality of life showed a notable presence of pain on the SF-36 among physicians at SAMU and especially among doctors who had worked for a longer length of time at SAMU.     

Unsuccessful emergency medical resuscitation--are continued efforts in the emergency department justified?

BACKGROUND. The majority of attempts to resuscitate victims of prehospital cardiopulmonary arrest are unsuccessful, and patients are frequently transported to the emergency department for further resuscitation efforts. We evaluated the efficacy and costs of continued hospital resuscitation for patients in whom resuscitation efforts outside the hospital have failed. METHODS. We reviewed the records of 185 patients presenting to our emergency department after an initially unsuccessful, but ongoing, resuscitation for a prehospital arrest (cardiac, respiratory, or both) by an emergency medical team. Prehospital and hospital characteristics of treatment for the arrest were identified, and the patients' outcomes in the emergency room were ascertained. The hospital course and the hospital costs for the patients who were revived were determined. RESULTS. Over a 19-month period, only 16 of the 185 patients (9 percent) were successfully resuscitated in the emergency department and admitted to the hospital. A shorter duration of prehospital resuscitation was the only characteristic of the resuscitation associated with an improved outcome in the emergency department. No patient survived until hospital discharge, and all but one were comatose throughout hospitalization. The mean stay in the hospital was 12.6 days (range, 1 to 132), with an average of 2.3 days (range, 1 to 11) in an intensive care unit. The total hospital cost for the 16 patients admitted was $180,908 (range per patient, $1,984 to $95,144). CONCLUSIONS. In general, continued resuscitation efforts in the emergency department for victims of cardiopulmonary arrest in whom prehospital resuscitation has failed are not worthwhile, and they consume precious institutional and economic resources without gain.     

Comparison between navigated reported position and postoperative computed tomography to evaluate accuracy in a robotic navigation system in total knee arthroplasty

BackgroundComputer navigation increases reproducibility compared to non-navigated total knee arthroplasty (TKA). Robotics navigation is a branch of computer navigation technology that might further improve accuracy of implant placement. The aim of this study is to assess the accuracy achieved in TKA with a robotic navigation system.MethodsOne hundred seventy three knees. System studied: Omni navigation System (OMNI, Raynham, MA). Navigated femoral and tibial cuts were compared to postoperative computed tomography (CT). Measurements reviewed: femoral coronal alignment (FCA), femoral sagittal alignment (FSA), femoral rotational alignment (FRA), tibial coronal alignment (TCA), tibial sagittal alignment (TSA) and hip–knee–ankle (HKA) angle. Statistical analysis was made using R.ResultsThe mean differences between the navigated reported and the CT positions were: FCA: 0.1 ± 1.2° more varus (P = 0.58), FSA: 1.5 ± 0.3° more flexed (P < 0.001), FRA: 0.0 ± 1.7° (P = 0.93), TCA: 0.7 ± 1.1° more varus (P < 0.001), TSA: − 1.3 ± 1.5 more negative slope (P < 0.001), HKA angle: 0.4 ± 2.4 more varus (P < 0.049).The percentages of concordance inside a three degree difference were: FCA: 98% (169 knees), FSA: 100% (173 knees), FRA: 94% (162 knees), TCA: 99% (171 knees), TSA: 93% (161 knees) and HKA angle: 83% (144 knees).ConclusionsThe current study showed that the robotic navigation system studied is highly accurate regarding final implant positioning for FCA, FRA and TCA. It has less accuracy in FSA, TSA and the HKA angle.     

Invasive pneumococcal disease in Indian adults: 11 years' experience

PurposeTo investigate the epidemiology of invasive pneumococcal disease (IPD), prevalent serotypes, and pattern of antimicrobial resistance (AMR) in Indian adults.MethodsProspective laboratory based surveillance of IPD was carried out in >18 years age group between January 2007 and July 2017, from a tertiary care hospital in South India. All Streptococcus pneumoniae culture positives from blood, CSF and sterile body fluids were characterized to identify the serotypes and AMR.ResultsA total of 408 IPD cases were characterized in this study. The overall case fatality rate in this study was 17.8% (95% confidence interval (CI): 14.1, 22.4). Pneumonia (39%), meningitis (24.3%), and septicaemia (18.4%) were the most common clinical conditions associated with IPD. Serotypes 1, 3, 5, 19F, 8, 14, 23F, 4, 19A and 6B were the predominant serotypes in this study. Penicillin non-susceptibility was low with 6.4%ConclusionSerotype data from this study helped in accurate estimation of pneumococcal conjugate vaccine-13 and pneumococcal polysaccharide vaccine-23 protective coverage against serotypes causing IPD in India as 58.7% (95% CI: 53.8, 63.4) and 67.4% (95% CI: 62.7, 71.8) respectively. Penicillin non-susceptibility in meningeal IPD cases is 27.4%. Empirical therapy for meningeal IPD must be cephalosporin in combination with vancomycin since cefotaxime non-susceptibility in meningeal IPD is 9.9%     

Acromion morphology and prevalence of rotator cuff tear: A systematic review and meta‐analysis

The causes of degenerative rotator cuff (RTC) tears are unclear but certain acromion morphology may contribute. This study's objective was to determine using a systematic review and meta‐analysis the association of acromion type and acromial index with the prevalence of RTC tears. Six databases were searched electronically. Seventeen relevant studies between 1993 and 2017 were included in the meta‐analyses determining the association of RTC tears with acromion type (n = 11) or acromial index (n = 10). Effect sizes were calculated as an odds ratio (OR) for the studies reporting acromion type and as raw mean difference (RMD) for the studies reporting acromial index. Meta‐analysis was performed using a random‐effects model. There was a significant small‐to‐medium effect found in the meta‐analysis for acromion type (overall OR = 2.82, P = 0.000003), indicating an almost three times greater odds for a RTC tear in individuals with a type‐III acromion as compared with those with a type‐I or ‐II. A significant effect was also found for acromial index (RMD = 0.071, P < 0.0000001), indicating that a larger acromial index is associated with a greater likelihood of a RTC tear. Because of substantial heterogeneity in RMD for acromial index (Q‐df = 92, P < 0.00001; I² = 89%), subgroup analyses and meta‐regressions were performed. Interestingly, the continent where the study was conducted (i.e., Europe vs. Asia) was the only moderator variable that could explain some of the acromial index heterogeneity. Overall, the findings from our analyses indicate that individuals with either a type‐III acromion and/or a larger acromial index have a greater likelihood for non‐traumatic RTC tears. Clin.

Symptoms of Traumatic Stress after Coronary Artery Bypass Grafting

Background: Traumatic stress symptoms have only recently been studied in association with medical treatment procedures. Purpose: The study examined associations of physical and psychological functioning during hospitalization to symptoms of traumatic stress after cardiac surgery. Methods: One hundred thirteen patients admitted for coronary artery bypass grafting participated in the study. Symptoms of traumatic stress were assessed one and six months after surgery, with the Impact of Event Scale. Preoperative stress and ruminative thinking, length of preoperative waiting, duration of surgery, and postoperative recovery indices (length of stay in the intensive care unit, cognitive functioning during intensive care, length of stay in the hospital) were examined. Results: Ten percent of the patients reported severe (> 19) symptoms of avoidance, and five percent reported severe symptoms of intrusion in both follow-ups. Hierarchical regression analyses showed that preoperative stress was positively associated to avoidance symptoms in both follow-ups (p < .01). Preoperative stress and ruminative thinking was positively associated to intrusion symptoms one month after surgery (p < .01). Disease related factors were not related to symptoms of traumatic stress during the postoperative period. Conclusion: This study highlights the role of preoperative surgery-related stress as a risk factor for traumatic stress in the postoperative period.     

Prehospital transport practices prevalent among patients presenting to the pediatric emergency of a tertiary care hospital

Background and Objectives:

Prehospital transport practices prevalent among children presenting to the emergency are under-reported. Our objectives were to evaluate the prehospital transport practices prevalent among children presenting to the pediatric emergency and their subsequent clinical course and outcome.

Methods:

In this prospective observational study we enrolled all children ≤17 years of age presenting to the pediatric emergency (from January to June 2013) and recorded their demographic data and variables pertaining to prehospital transport practices. Data was entered into Microsoft Excel and analyzed using Stata 11 (StataCorp, College Station, TX, USA).

Results:

A total of 319 patients presented to the emergency during the study period. Acute gastroenteritis, respiratory tract infection and fever were the most common reasons for presentation to the emergency. Seventy-three (23%) children required admission. Most commonly used public transport was auto-rickshaw (138, 43.5%) and median time taken to reach hospital was 22 min (interquartile range: 5, 720). Twenty-six patients were referred from another health facility. Of these, 25 were transported in ambulance unaccompanied. About 8% (25) of parents reported having difficulties in transporting their child to the hospital and 57% (181) of parents felt fellow passengers and drivers were unhelpful. On post-hoc analysis, only time taken to reach the hospital (30 vs. 20 min; relative risk [95% confidence interval]: 1.02 [1.007, 1.03], P = 0.003) and the illness nature were significant (45% vs. 2.6%; 0.58 [0.50, 0.67], P ≤ 0.0001) on multivariate analysis.

Conclusions:

In relation to prehospital transport among pediatric patients we observed that one-quarter of children presenting to the emergency required admission, the auto-rickshaw was the commonest mode of transport and that there is a lack of prior communication before referring patients for further management.     

Investigating infection management and antimicrobial stewardship in surgery: a qualitative study from India and South Africa

ObjectivesTo investigate the drivers for infection management and antimicrobial stewardship (AMS) across high-infection-risk surgical pathways.MethodsA qualitative study—ethnographic observation of clinical practices, patient case studies, and face-to-face interviews with healthcare professionals (HCPs) and patients—was conducted across cardiovascular and thoracic and gastrointestinal surgical pathways in South Africa (SA) and India. Aided by Nvivo 11 software, data were coded and analysed until saturation was reached. The multiple modes of enquiry enabled cross-validation and triangulation of findings.ResultsBetween July 2018 and August 2019, data were gathered from 190 hours of non-participant observations (138 India, 72 SA), interviews with HCPs (44 India, 61 SA), patients (six India, eight SA), and case studies (four India, two SA). Across the surgical pathway, multiple barriers impede effective infection management and AMS. The existing implicit roles of HCPs (including nurses and senior surgeons) are overlooked as interventions target junior doctors, bypassing the opportunity for integrating infection-related care across the surgical team. Critically, the ownership of decisions remains with the operating surgeons, and entrenched hierarchies restrict the inclusion of other HCPs in decision-making. The structural foundations to enable staff to change their behaviours and participate in infection-related surgical care are lacking.ConclusionsIdentifying the implicit existing HCP roles in infection management is critical and will facilitate the development of effective and transparent processes across the surgical team for optimized care. Applying a framework approach that includes nurse leadership, empowering pharmacists and engaging surgical leads, is essential for integrated AMS and infection-related care.     

Antibiotic audit in medicine intensive care unit of tertiary care centre: A must do exercise

PurposeAntimicrobial resistance (AMR) is a serious threat to the humanity now a days. To prevent it, the first step is to know about our antibiotic practices. Audit is the first step in continuous quality improvement which intend to go ahead. Antibiotic stewardship involves appropriate antibiotic (empirical or definitive) at correct time in correct doses and frequency for appropriate duration.MethodWe conducted a retrospective study in intensive care unit at our tertiary care center of Bihar, India. Our aim was to know about empirical antibiotic we are prescribing in suspected sepsis patients and their rationality too. National treatment guidelines for infectious disease released by National Centre for Disease Control (NCDC) was taken as standard of care. We recorded demographic profile, SOFA (Sequential Organ Failure Assessment), APACHE II (Acute Physiology and Chronic Health Evaluation), antibiotic prescribed, final etiology of infection, and outcome of the patient and total ICU stay.ResultWe found that combination of two antibiotics were given in majority of patients (53%) and the third generation cephalosporin was the most commonly prescribed antibiotic. In our audit, rational combinations according to the antibiotic policies were given in 73.7% of patients. Appropriate doses of antibiotics were given in 89.5% of patients.ConclusionAudit is a mandatory exercise to provide quality care in the health care system.     

Seroprevalence of SARS-CoV-2 specific IgG antibodies among eye care workers in South India

PurposeHealth care workers are at higher risk of acquiring the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. This study aims to understand the seroprevalence of anti-SARS-CoV-2 IgG antibody among the eye care workers in South India.MethodsThe participants included eye care workers from the nine eye care centres. All the participants were interviewed with a questionnaire to obtain essential information about socio-demographics, past contact with COVID-19 patients and additional information as recommended by Indian Council of Medical Research, India. Serum samples were tested for anti-SARS-CoV-2 IgG antibodies by ELISA.ResultsA total of 1313 workers were included and 207 (15.8%) were positive for the SARS-CoV-2 IgG antibody. The seropositivity was higher in the moderate risk group (19.5%) followed by low (18.6%) and high risk (13.7%) groups. The seropositivity was significantly higher among i) day scholars compared to hostellers (OR - 2.22, 1.56 to 3.15, P ​< ​0.0001), ii) individuals with history of flu-like illness (4.57, 3.08–6.78, P ​< ​0.001) or who were symptomatic or in contact with COVID 19 positive cases (2.2, 1.02–4.75, P – 0.043) and iii) individuals with history of systemic illness (2.11, 1.39–3.21, P ​< ​0.001). Individuals (11.97%) who had no history of contact or any illness were also seropositive.ConclusionsThe effectiveness of the protective measures taken against COVID infection was evident from the lower percentage of seropositivity in the high risk group. The study highlighted the need to create awareness among individuals to follow strict safety measures even in non-work hours and also in social circles.     

Epidemiology of road traffic crashes among long distance drivers in Ibadan,Nigeria

Background

Road Traffic Crashes (RTCs) are major causes of morbidity and mortality in Nigeria. Few studies in Ibadan have focused on the distribution and determinants of RTC among long distance drivers.

Objective

To describe the distribution of crashes by place, times of occurrence, characteristics of persons involved and identify associated factors.

Methods

A cross-sectional study was carried out among consenting long distance drivers within selected parks in Ibadan.

Results

Respondents (592) were males, with median age of 42.0 years (range 22.0–73.0 years). Secondary education was the highest level of education attained by 38.0%. About 34.0% reported current use of alcohol. The life-time prevalence of crashes was 35.3% (95% CI= 31.5–39.2%) and 15.9% (95% CI=13.1–19.0%) reported having had at least one episode of crash in the last one year preceding the study. The crash occurred mainly on narrow roads [32/94 (34.0%,)] and bad portions of tarred roads [35/94 (37.2%,)] with peak of occurrence on Saturdays 18/94 (19.1%,). Significantly higher proportions of drivers aged ≤39years (23.4%) versus >39years (11.7%), those with no education (29.9%) versus the educated (13.8%) and those who reported alcohol use (21.9%) versus non users (12.8%) were involved in crashes in the year preceding the study. Significant predictor of the last episode of crashes in the last one year were age (OR=2.2, 95% CI=1.4–3.5), education (OR=2.7, 95% CI=1.5–4.6) and alcohol use (OR=1.8, 95% CI=1.2–3.0).

Conclusion

Road traffic crashes occurred commonly on bad roads, in the afternoon and during weekends, among young and uneducated long-distance drivers studied. Reconstruction of bad roads and implementation of road safety education programmes aimed at discouraging the use of alcohol and targeting the identified groups at risk are recommended.     

Causes of injuries resulting in a visit to the emergency department of a Provincial General Hospital, Nyanza, western Kenya

Background

There is increasing importance of trauma not only as a major cause of surgical admissions, but also a significant cause of morbidity, mortality and disability.

Objective

To document injury-related visits and hospitalization in a provincial hospital, western Kenya.

Methods

On-site review of records of all patients who visited emergency department (ED) from January 2002 through December 2003, and admissions of year 2003.

Results

A total of 15365 patients visited the ED, of which 41% (6319/15395) were injury cases. The leading causes of injury were assault (42%), road traffic crashes (RTC) (28%), unspecified soft tissue injury (STI) (11%). Cut-wounds, dog-bites, falls, burns and poisoning were infrequently reported (each <10%). The age group 15–44 years formed the largest proportion (75%). A total of 3253 patients were admitted in 2003, of which 1010 (31%) were due to injuries. RTC were leading cause of hospitalization (49%) followed by assault (16%). Men were more likely to be hospitalized due to assault (OR=2.22; CI = 1.45 – 3.41) and not burns or poisoning (p<0.01). There were 64 (6.3%) injury-related deaths, mainly resulting from RTC (41.9%), burns (19.4%) and assault (16.1%).

Conclusions

This study provides considerable information on major causes of injuries, useful for epidemiological surveillance and injury prevention campaigns.     

The accuracy of prehospital diagnosis of acute cerebrovascular accidents: an observational study

Introduction

Time to treatment is the key factor in stroke care. Although the initial medical assessment is usually made by a non-neurologist or a paramedic, it should ensure correct identification of all acute cerebrovascular accidents (CVAs). Our aim was to evaluate the accuracy of the physician-made prehospital diagnosis of acute CVA in patients referred directly to the neurological emergency department (ED), and to identify conditions mimicking CVAs.

Material and methods

This observational study included consecutive patients referred to our neurological ED by emergency physicians with a suspicion of CVA (acute stroke, transient ischemic attack (TIA) or a syndrome-based diagnosis) during 12 months. Referrals were considered correct if the prehospital diagnosis of CVA proved to be stroke or TIA.

Results

The prehospital diagnosis of CVA was correct in 360 of 570 cases. Its positive predictive value ranged from 100% for the syndrome-based diagnosis, through 70% for stroke, to 34% for TIA. Misdiagnoses were less frequent among ambulance physicians compared to primary care and outpatient physicians (33% vs. 52%, p < 0.001). The most frequent mimics were vertigo (19%), electrolyte and metabolic disturbances (12%), seizures (11%), cardiovascular disorders (10%), blood hypertension (8%) and brain tumors (5%). Additionally, 6% of all admitted CVA cases were referred with prehospital diagnoses other than CVA.

Conclusions

Emergency physicians appear to be sensitive in diagnosing CVAs but their overall accuracy does not seem high. They tend to overuse the diagnosis of TIA. Constant education and adoption of stroke screening scales may be beneficial for emergency care systems based both on physicians and on paramedics.     

A study on viral haemorrhagic fever due to dengue,chikungunya and Crimean Congo haemorrhagic fever virus among patients attending tertiary care hospital in North East India

PurposeThe present study was undertaken with the objective to study the common etiology of Viral Haemorrhagic Fever (VHF) among patients attending tertiary health care centre in NE India and also to study the clinico-demographic profile of such patients. The agents of VHF included in the study were dengue, chikungunya and Crimean Congo haemorrhagic fever (CCHF) virus. The inclusion of CCHF was based on evidence of seroprevalence in livestock (bovine, sheep and goat) in various North Eastern states.Materials and methodsSerum samples were collected from 51 suspected VHF patients. MAC-ELISA was done to detect dengue and chikungunya specific IgM antibody. The samples were also tested by real-time RT-PCR for detection of dengue, chikungunya and CCHF specific nucleic acid. The laboratory and clinico-demographic profile of these patients were noted in detail.ResultsSerum samples of 16 of 51 suspected cases were confirmed to be suffering from VHF. Among these confirmed cases, 12 were diagnosed with dengue haemorrhagic fever, one was diagnosed with chikungunya and three were diagnosed with dengue-chikungunya co-infection. Based on severity, DHF was further classified into- DHF I- (4,26.6%), DHF II (6,40%), DHF III (3,20%) and DHF IV (2,13.3%). There was no CCHFV infection detected in our study. Retro-orbital pain (P ?= ?0.02) and haematocrit level (P ?= ?0.03) were found to be statistically significant.ConclusionsThis study reiterates the fact that CCHF virus infection is still probably absent in human population of NE India and haemorrhagic symptoms, though rare maybe one of the atypical manifestations of chikungunya infection.     

Severe road traffic injuries in Kenya, quality of care and access

Background

Road traffic injuries (RTI) are on increase in developing countries. Health care facilities are poorly equipped to provide the needed services.

Objective

Determine access and quality of care for RTI casualties in Kenya.

Design

Cross-sectional survey

Setting

53 large and medium size private, faith-based and public hospitals.

Participants

In-patient road traffic crash casualties and health personnel in the selected hospitals were interviewed on availability of emergency care and resources. Onsite verification of status was undertaken.

Results

Out of 310 RTI casualties interviewed, 72.3%, 15.6% and 12.2% were in public, faith-based and private hospitals, respectively. Peak age of the injured was 15–49 years. First aid was availed to 16.0% of casualties. Unknown persons transported 76.5% of the injured. Police and ambulance vehicles transported 6.1% and 1.4%, respectively. 51.9% reached health facilities within 30 minutes of crash and medical care provided to 66.2% within one hour. 40.8% of recipient facilities were adequately prepared for RTI emergencies.

Conclusions

Most RTI casualties were young and from poor backgrounds. Training of motorists and general public in first aid should be considered in RTI control initiatives. Availability of basic trauma care medical supplies in public health facilities was highly deficient.     

Parenteral nutrition support: Beyond gut feeling? Quality control study of parenteral nutrition practices in a Tertiary Care Hospital

Background:Enteral nutrition (EN) is preferred over parenteral nutrition (PN) in hospitalized patients based on International consensus guidelines. Practice patterns of PN in developing countries have not been documented.Objectives:To assess practice pattern and quality of PN support in a tertiary hospital setting in Chennai, India.Methods:Retrospective record review of patients admitted between February 2010 and February 2012.Results:About 351,008 patients were admitted to the hospital in the study period of whom 29,484 (8.4%) required nutritional support. About 70 patients (0.24%) received PN, of whom 54 (0.18%) received PN for at least three days. Common indications for PN were major gastrointestinal surgery (55.6%), intolerance to EN (25.9%), pancreatitis (5.6%), and gastrointestinal obstruction (3.7%).Conclusions:The proportion of patients receiving PN was very low. Quality issues were identified relating to appropriateness of indication and calories and proteins delivered. This study helps to introspect and improve the quality of nutrition support.     

Analysis of Characteristics and Mortality in Cardiac Arrest Patients by Hospital Level: a Nationwide Population-based Study

BackgroundSurvival and post-cardiac arrest care vary considerably by hospital, region, and country. In the current study, we aimed to analyze mortality in patients who underwent cardiac arrest by hospital level, and to reveal differences in patient characteristics and hospital factors, including post-cardiac arrest care, hospital costs, and adherence to changes in resuscitation guidelines.MethodsWe enrolled adult patients (≥ 20 years) who suffered non-traumatic cardiac arrest from 2006 to 2015. Patient demographics, insurance type, admission route, comorbidities, treatments, and hospital costs were extracted from the National Health Insurance Service database. We categorized patients into tertiary hospital, general hospital, and hospital groups according to the level of the hospital where they were treated. We analyzed the patients'' characteristics, hospital factors, and mortalities among the three groups. We also analyzed post-cardiac arrest care before and after the 2010 guideline changes. The primary end-point was 30 days and 1 year mortality rates.ResultsThe tertiary hospital, general hospital, and hospital groups represented 32.6%, 49.6%, and 17.8% of 337,042 patients, respectively. The tertiary and general hospital groups were younger, had a lower proportion of medical aid coverage, and fewer comorbidities, compared to the hospital group. Post-cardiac arrest care, such as percutaneous coronary intervention, targeted temperature management, and extracorporeal membrane oxygenation, were provided more frequently in the tertiary and general hospital groups. After adjusting for age, sex, insurance type, urbanization level, admission route, comorbidities, defibrillation, resuscitation medications, angiography, and guideline changes, the tertiary and general hospital groups showed lower 1-year mortality (tertiary hospital vs. general hospital vs. hospital, adjusted odds ratios, 0.538 vs. 0.604 vs. 1; P < 0.001). After 2010 guideline changes, a marked decline in atropine use and an increase in post-cardiac arrest care were observed in the tertiary and general hospital groups.ConclusionThe tertiary and general hospital groups showed lower 30 days and 1 year mortality rates than the hospital group, after adjusting for patient characteristics and hospital factors. Higher-level hospitals provided more post-cardiac arrest care, which led to high hospital costs, and showed good adherence to the guideline change after 2010.     

The Comparison of Emergency Medical Service Responses to and Outcomes of Out-of-hospital Cardiac Arrest before and during the COVID-19 Pandemic in an Area of Korea

BackgroundSince the declaration of the coronavirus disease 2019 (COVID-19) pandemic, COVID-19 has affected the responses of emergency medical service (EMS) systems to cases of out-of-hospital cardiac arrest (OHCA). The purpose of this study was to identify the impact of the COVID-19 pandemic on EMS responses to and outcomes of adult OHCA in an area of South Korea.MethodsThis was a retrospective observational study of adult OHCA patients attended by EMS providers comparing the EMS responses to and outcomes of adult OHCA during the COVID-19 pandemic to those during the pre-COVID-19 period. Propensity score matching was used to compare the survival rates, and logistic regression analysis was used to assess the impact of the COVID-19 pandemic on the survival of OHCA patients.ResultsA total of 891 patients in the pre-COVID-19 group and 1,063 patients in the COVID-19 group were included in the final analysis. During the COVID-19 period, the EMS call time was shifted to a later time period (16:00–24:00, P < 0.001), and the presence of an initial shockable rhythm was increased (pre-COVID-19 vs. COVID-19, 7.97% vs. 11.95%, P = 0.004). The number of tracheal intubations decreased (5.27% vs. 1.22%, P < 0.001), and the use of mechanical chest compression devices (30.53% vs. 44.59%, P < 0.001) and EMS response time (median [quartile 1-quartile 3], 7 [5–10] vs. 8 [6–11], P < 0.001) increased. After propensity score matching, the survival at admission rate (22.52% vs. 18.24%, P = 0.025), survival to discharge rate (7.77% vs. 5.52%, P = 0.056), and favorable neurological outcome (5.97% vs. 3.49%, P < 0.001) decreased. In the propensity score matching analysis of the impact of COVID-19, odds ratios of 0.768 (95% confidence interval [CI], 0.592–0.995) for survival at admission and 0.693 (95% CI, 0.446–1.077) for survival to discharge were found.ConclusionDuring the COVID-19 period, there were significant changes in the EMS responses to OHCA. These changes are considered to be partly due to social distancing measures. As a result, the proportion of patients with an initial shockable rhythm in the COVID-19 period was greater than that in the pre-COVID-19 period, but the final survival rate and favorable neurological outcome were lower.
