Analysis of prehospital perimortem caesarean deliveries performed by Helicopter Emergency Medical Services in the Netherlands and recommendations for the future.

BACKGROUND: Prehospital perimortem caesarean delivery (PCD) is a rarely performed procedure. In this study, we aimed to examine all PCDs performed by the four Helicopter Emergency Medical Services in the Netherlands; to describe the procedures, outcomes, complications, and compliance with the recommended guidelines; and to formulate recommendations. METHODS: We performed a population-based retrospective cohort study of all consecutive maternal out-of-hospital cardiac arrests that underwent PCD in the prehospital setting between May 1995 and December 2019. Registered data included patient demographics, operator background, advanced life support interventions, and timelines. Resuscitation performance was evaluated according to the 2015 European Resuscitation Guidelines. RESULTS: Seven patients underwent a prehospital PCD. Three mothers died on the scene, while four were transported to a hospital but died in the hospital. Seven neonates were born by PCD. One neonate died on the scene and six were transported to a hospital. Three neonates were eventually discharged from the hospital. Among the three surviving neonates, the periods from dispatch to start of PCD were 13, 14, and 21 min. CONCLUSIONS: There was a low incidence of maternal perimortem caesarean deliveries in The Netherlands. Only some neonates survived after PCD. It is recommended that PCD be performed as quickly as possible. Due to the delay, the mother has a far lower chance of survival than the neonate. In fatal cases, autopsy is strongly recommended.

Results on patient flow of implementing an Acute Medical Unit.

BACKGROUND: There is an increased influx of patients needing admission. Introducing an acute medical unit (AMU) may increase the admission capacity without increasing the total number of beds. METHODS: Data collected during the first four years after implementation of an AMU in an academic tertiary care center in Amsterdam were analyzed. RESULTS: A 24 bed unit was realized. The total number of admissions increased in the first year with 977 (16%), with an additional 4.1% increase after 2 years with stabilization thereafter. The length of stay decreased, the absolute number of refusals declined, the number of readmissions remained unchanged. CONCLUSION: Introduction of AMUs in overcrowded services could be beneficial in improving the strain on the acute healthcare systems.

Improving care for older patients in the acute setting: a qualitative study with healthcare providers.

BACKGROUND: The proportion of older people needing acute care is rapidly growing, thereby posing an increased burden on the acute care chain. The aim of this study is to gain more insight into the obstacles and potential improvement opportunities of the acute care process for older patients arriving at the hospital. METHODS: Semi-structured interviews were conducted to determine the experiences of 18 different primary (i.e. general practitioner, community nurse) and secondary healthcare professionals (i.e. emergency department (ED) nurse, ED physician, geriatric physician, geriatric nurse, ambulance nurse, acute medical unit nurse), and three experts (2 researchers, 1 older adult advisor). RESULTS: Four core themes emerged from the interviews: 1) The concept of frailty, awareness concerning frail older patients, and identification of frailty, 2) Barriers in the care process of older patients within the acute care chain, 3) Optimising the discharge process of older patients, and 4) Improvement opportunities suggested by the respondents. Early identification of frailty, improving the continuity of care by means of structured information exchange between care providers in the acute care chain, and a more generalist approach were considered important by the respondents in order to deliver appropriate care to older patients. CONCLUSION: This explorative study identified several barriers and improvement opportunities which are important to improve the quality, efficacy and appropriateness of the acute care of older patients. More seems needed in the future in order to share experiences, expertise and develop potential improvement strategies for the acute care of older patients.

[Lessons learned from the evacuation of the VU University Medical Centre after flooding]. / Lessen uit de evacuatie van het VUmc na wateroverlast.

On 8 September 2015, flooding of the lower floors of the VU University Medical Center in Amsterdam caused serious damage to many vital technical services, such as water and power supplies. The decision was made to completely evacuate the university hospital. This paper describes the chronology and events of that day and shares a number of important lessons that were learned, in order to help readers to optimise crisis organisation in their own institutions. A serious situation or disaster can never be standardised in protocols or manuals; flexibility, improvisation and confidence in one another's expertise and commitment are therefore essential.

What are we waiting for? Factors influencing completion times in an academic and peripheral emergency department.

BACKGROUND: A long completion time in the Emergency Department (ED) is associated with higher morbidity and in-hospital mortality. A completion time of more than four hours is a frequently used cut-off point. Mostly, older and sicker patients exceed a completion time of four hours on the ED. The primary aim was to examine which factors currently contribute to overcrowding and a time to completion of more than four hours on the EDs of two different hospitals, namely: the VU Medical Center (VUmc), an academic level 1 trauma centre and the St. Antonius Hospital, a large community hospital in Nieuwegein. In addition, we compared the differences between these hospitals. METHODS: In this observational study, the time steps in the process of diagnosing and treatment of all patients visiting the EDs of the two hospitals were measured for four weeks. Patients triaged as Emergency Severity Index (ESI) category 2/3 or Manchester Triage System (MTS) orange/yellow were followed more closely and prospectively by researchers for detailed information in the same period from 12.00-23.00 hrs. RESULTS: In the VUmc, 89% of the patients had a completion time of less than four hours. The average completion time (n = 2262) was 2:10 hours, (median 1:51 hours, range: 0:05-12:08). In the St. Antonius Hospital, 77% of patients had a completion time shorter than four hours (n = 1656). The average completion time in hours was 2:49 (n = 1655, median 2:34, range: 0:08-11:04). In the VUmc, a larger percentage of ESI 1, 2 and 3 patients did not achieve the 4-hour target (14%, 20% and 19%) compared with ESI 4 and 5 patients (2.7% and 0%), p < 0.001. At the St. Antonius Hospital, a greater percentage of orange and yellow categorised patients exceeded four hours on the ED (32% and 28%) compared with red (8%) and green/blue (13%), p < 0.001. For both hospitals there was a significant dependency between exceeding four hours on the ED and the following: whether a consultation was performed (p < 0.001), the number of radiology tests performed (p < 0.001), and an age above 65 years. CONCLUSION: Factors leading to ED stagnation were similar in both hospitals, namely old age, treatment by more than one speciality and undergoing radiological tests. Uniform remedial measures should be taken on a nationwide level to deal with these factors to reduce stagnation in the EDs.

Hospital admissions of patients aged over 80 with acute abdominal complaints.

OBJECTIVE: Evaluation of the outcome of patients aged over 80 with acute abdominal complaints, who were admitted to the hospital through the emergency department. DESIGN: Retrospective study. SETTING: City hospital, the Netherlands. PATIENTS: 132 patients aged over 80 with acute abdominal complaints who were admitted through the emergency department in 1997. MAIN OUTCOME MEASURES: Diagnosis at admission and discharge or necropsy, diagnostic tests, treatment, morbidity, and mortality. RESULTS: In 27 of 132 patients (20%) the diagnosis on discharge or at necropsy differed from the initial diagnosis in the emergency department; in 18 patients (14%) an important diagnosis was missed and the severity was underestimated. Within the first 24 hours, 97% (n = 128) had blood tests, 63% (n = 83) urine tests, 58% (n = 76) plain radiograph of the abdomen, 20% (n = 26) ultrasonography, and 3% (n = 4) computed tomography (CT) of the abdomen. Of all the patients admitted, 35 (27%) were operated on. The hospital mortality of the admitted patients was 17% (n = 23) and of those operated on 34% (n = 12). The mortality in the 27 misdiagnosed patients was 59% (n = 16). The morbidity among the 109 surviving patients was 22%. CONCLUSIONS: Mortality was high among those aged over 80 with acute abdominal complaints who were admitted through the emergency department, particularly among those who were operated on and those who were misdiagnosed. Guidelines for an earlier and more comprehensive diagnostic approach could lead to better insight into the prognosis and thereby to more adequate and better-targeted treatment.

The functional and clinical significance of the Met-->Thr substitution in Kringle IV type 10 of apolipoprotein(a).

Lipoprotein(a) [Lp(a)], an independent risk factor for the development of atherosclerosis, contains an apolipoprotein(a) [apo(a)] moiety covalently linked to a LDL moiety. Apo(a) is a glycoprotein homologous to plasminogen as it contains multiple repeats of a lysine binding domain resembling plasminogen kringle IV (K.IV). The multiple K.IV repeats can be differentiated in ten types that show a variation in their lysine binding capacity. Since K.IV type 10 shows the highest conservation of the amino acids postulated to form the lysine binding pocket, this kringle is suggested to be the main lysine binding site of apo(a). Recently, a T-->C polymorphism in the apo(a)-gene was reported, leading to a Met-->Thr substitution at amino acid position 66 of K.IV type 10, in the vicinity of the postulated lysine binding pocket. To investigate the significance of this substitution on some in vitro characteristics of Lp(a), the affinity for lysine-Sepharose and the binding affinity for limited plasmin digested des AA fibrin (Desafib-X) of the two subtypes was determined using plasma of donors homozygous for the polymorphism. These studies revealed a large heterogeneity in the binding characteristics, irrespective of the subtype. The comparison of the allele frequencies of this polymorphism in 155 patients having symptomatic atherosclerosis versus 153 normolipidemic controls revealed no significant differences. In conclusion, this study suggests that the presence of either a Met66 or a Thr66 residue in K.IV type 10 of apo(a) has no consequences for the binding characteristics of Lp(a) toward lysine-Sepharose or Desafib-X, nor is it associated with the presence of symptomatic atherosclerosis.
