Ensihoidon laatumittarin kehittäminen, testaaminen ja käyttöönotto

Ensihoito on nuori sairaanhoidon erikoisala, joka on kehittynyt Suomessa viimeisen kymmenen vuoden aikana huomattavasti. Kehitys on lähes yksinomaan tapahtunut lääketiede edellä. Hoitoja joita aikaisemmin suoritettiin sairaaloissa, suoritetaan nykyään potilaan kotona. Hoidon laadun systemaattinen mittaaminen on ensihoidon kehitystyössä jäänyt lääketieteellisen kehityksen jalkoihin. Tämän kehittämisprojektin tavoitteena oli kehittää ja ottaa käyttöön ensihoidon prosessilaatumittari rintakipupotilaan osalta. Kehittämisprojektiin kuuluvan tutkimuksellisen osuuden tavoitteena oli selvittää hoitotason ensihoitajien antaman hoidon laatu Varsinais-Suomen pelastuslaitoksella. Tutkimukseen valittiin 100 ensihoitotehtävää usealta ajankohdalta vuodelta 2014, joissa kuljetuskoodina oli A, B tai C704. Tutkimukseen valittujen ensihoitokaavakkeisiin kirjattuja tietoja verrattiin voimassa oleviin hoito-ohjeisiin. Tutkimuksen tarkoituksena oli testata kehitettyä laatumittaria rintakipupotilaan ensihoidon laadunarvioinnin työkaluna. Tutkimuksen yleisenä johtopäätöksenä voidaan todeta, että hoitotason ensihoitajat eivät noudata voimassa olevia hoito-ohjeita rintakipupotilaan osalta. Saadut tulokset vastaavat aikaisemmin kirjallisuudessa mainittuja tuloksia ensihoitajien hoito-ohjeiden noudattamisesta. Tutkimusta varten luotu mittari on yksinkertainen ja helppo käyttää mitattaessa ensihoitajien antaman kirjatun hoidon laatua.Prehospital emergency care is a relatively new health care specialty in Finland. Modern prehospital emergency care has only been around for a decade and the development of it has mainly been medicine driven. Treatments that have previously been available only in hospitals have been brought into patients´ homes. Due to this medical advancement, systematic measurement of the quality of pre-hospital emergency care has been neglected. The aim of this project was to develop and apply a process quality meter for chest pain patients in prehospital emergency care setting. The aim of the study was to find out how the level of care, given by the paramedics to the chest pain patients, corresponds to the prehospital emergency care guidelines of the Hospital District of Southwest Finland. A total of 100 chest-pain patient records, filled during 2014, were selected as the study material. These records were compared to the existing prehospital emergency care clinical guidelines. The main conclusion is that paramedics do not follow the prehospital emergency care clinical guidelines. These findings correspond to previous studies. The quality meter developed as the result of the thesis, is simple and easy to use to measure the quality of the care given to the patients with chest pain

Upper limb dysfunction and activities in daily living in idiopathic normal pressure hydrocephalus

Background Idiopathic normal pressure hydrocephalus (iNPH) is a neurodegenerative disease with a characteristic symptom triad of gait disturbance, cognitive decline, and incontinence. Recently, also dysfunctions in upper limbs have been described in iNPH and reported to improve after shunt surgery. We aim to describe the role of upper limb motor function in the clinical assessment of iNPH patients and its influence on activities of daily living (ADL). Methods Seventy-five consecutive patients with probable iNPH were studied pre-operatively and at 3 and 12 months after shunt surgery. The pre-operative evaluation included lumbar drainage of cerebrospinal fluid (tap test). Motor functions were assessed in upper and lower limbs with Grooved Pegboard Test (GPT), Box & Block Test (BBT), Total Score of Gait (TSG), and balance test. ADL was assessed with Barthel's index and cognition in accordance with the Consortium to Establish a Registry for Alzheimer's Disease (CERAD). Results Patients showed improvement in all motor tests and ADL at 3 months after shunt surgery. The improvement remained stable during the 12-month post-operative follow-up. The motor function tests correlated with each other and with ADL. Conclusions A 3-month follow-up period after shunt surgery is adequate to show improvement in motor tasks, and a positive outcome will last for at least 12 months. A shunt-responsive dysfunction of upper limb motor performance plays a major role in ADL of iNPH patients. Therefore, we suggest an evaluation of upper limb motor performance to be included in routine evaluation of iNPH patients.Peer reviewe

Incidence and risk factors of spinal cord stimulation for persistent or recurrent pain after lumbar spine surgery : a population-based study

Purpose This study aims to elucidate the incidence of and independent risk factors for spinal cord stimulator implantations for patients who underwent lumbar spine surgery. Methods The PERFormance, Effectiveness, and Cost of Treatment (PERFECT) episodes database, which was established for selected diseases and procedures in Finland, includes all patients who underwent lumbar spine surgery for degenerative spine conditions or spinal cord stimulation (SCS) in Finland from 1986 to 2018. The data on age, sex, hospital diagnoses, surgical procedures, and causes of death were imported from the Finnish national registers into the PERFECT database. Results Between 1986 and 2018, 157,824 patients had their first lumbar spine procedure and for 1769 (1.1%) of them, a subsequent SCS procedure was observed during the follow-up. The cumulative incidence of SCS for persistent or recurrent pain after lumbar disk herniation, spinal stenosis, degenerative disk disease, and spondylolysis and spondylolisthesis surgery at 15 years was 1.2%, 1.0%, 2.7%, and 2.6% respectively. At 15 years, the cumulative incidence of SCS for persistent or recurrent pain after lumbar spine surgery after five or more lumbar spinal operations was 11.9%. Conclusion Repeated surgery was the most prominent significant risk factor for SCS for persistent or recurrent pain after lumbar spine surgery. The risk of SCS for persistent or recurrent pain after lumbar spine surgery increases significantly along with the number of lumbar spine procedures. When considering repeated lumbar spine surgery, careful evaluation of treatment options should take place to ensure good patient outcomes.Peer reviewe

Psychiatric disorders are a common prognostic marker for worse outcome in patients with idiopathic intracranial hypertension

Objective Idiopathic intracranial hypertension (IIH) is aetiologically unknown disorder that associates with endocrinological disturbances, including dysfunction of hypothalamic-pituitary-adrenal-axis. Neuroendocrinological dysfunctions have also been characterized in psychiatric disorders, and therefore we investigated the presence of psychiatric disorders of patients with IIH in a well-defined cohort. Patients and Methods A total of 51 patients with IIH were included. Patient demographics, symptoms, imaging data, ophthalmological and clinical findings were collected. Results At the time of diagnosis the mean age was 32.5years (SD 10.7), the body mass index was 37.1 kg/m2 (SD 7.4), and the opening pressure 29.1 mmHg (SD 6.2). A total of 88.2% of patients were female and 45.1% were diagnosed with a psychiatric co-morbidity prior to IIH diagnosis. The mean follow-up time was 4.4 years (SD 5.4). The overall treatment outcome was significantly poorer on a group of patients with psychiatric diagnosis when compared to individuals without such history (p = 0.001), but there were no differences in the resolution of papilledema (p = 0.405). Patients with IIH and psychiatric disorders had more often empty sella on their imaging at diagnosis when compared to patients without psychiatric co-morbidity (p = 0.044). Conclusion Psychiatric disorders are highly prevalent in patients with IIH and associate with worse subjective outcomes. These findings advocate for monitoring the mental health of patients with IIH and warrant further multidisciplinary research to understand the potentially underlying psychosocial and neuroendocrinological mechanisms.Peer reviewe

5-Year health-related quality of life outcome in patients with idiopathic normal pressure hydrocephalus

Background Health-related quality of life (HRQoL) is severely impaired in persons with idiopathic normal pressure hydrocephalus (iNPH). The HRQoL improves in a number of patients after the placement of a cerebrospinal fluid (CSF) shunt, but long-term follow-up of HRQoL is rare. Methods Extended follow-up (60 months) of a prospective cohort study involving 189 patients with iNPH who underwent shunt surgery. Preoperative variables were used to predict favorable HRQoL outcome (improvement or non-deterioration) measured by the 15D instrument 5 years after shunting. Results Out of the 189 initially enrolled study participants, 88 had completed 5-year HRQoL follow-up (46%), 64 had died (34%), and 37 (20%) failed to complete the HRQoL follow-up but were alive at the end of the study. After initial post-operative HRQoL improvement, HRQoL deteriorated so that 37/88 participants (42%) had a favorable HRQoL outcome 5 years after shunting. Multivariate binary logistic regression analysis indicated that younger age (adjusted OR 0.86, 95% CI 0.77-0.95; p <0.005), lower body mass index (adjusted OR 0.87, 95% CI 0.77-0.98; p <0.05) and better Mini-Mental State Examination performance (adjusted OR 1.16, 95% CI 1.01-1.32; p <0.05) before surgery predicted favorable 5-year outcome. Conclusions This extended follow-up showed that the self-evaluated HRQoL outcome is associated with iNPH patients' pre-operative cognitive status, overweight and age. The post-operative deterioration may reflect the natural progression of iNPH, but also derive from aging and comorbidities. It indicates a need for long-term follow-up.Peer reviewe

In vivo assessment of Lewy body and beta-amyloid copathologies in idiopathic normal pressure hydrocephalus: prevalence and associations with clinical features and surgery outcome

Background: Idiopathic normal pressure hydrocephalus (iNPH) is a clinico-radiological syndrome of elderly individuals likely sustained by different neurodegenerative changes as copathologies. Since iNPH is a potentially reversible condition, assessing neurodegenerative pathologies in vitam through CSF biomarkers and their influence on clinical features and surgical outcome represents crucial steps.Methods: We measured a-synuclein seeding activity related to Lewy body (LB) pathology by the real-time quaking-induced conversion assay (RT-QuIC) and Alzheimer disease core biomarkers (proteins total-tau, phospho-tau, and amyloid-beta) by immunoassays in the cerebrospinal fluid (CSF) of 293 iNPH patients from two independent cohorts. To compare the prevalence of LB copathology between iNPH participants and a control group representative of the general population, we searched for a-synuclein seeding activity in 89 age-matched individuals who died of Creutzfeldt-Jakob disease (CJD). Finally, in one of the iNPH cohorts, we also measured the CSF levels of neurofilament light chain protein (NfL) and evaluated the association between all CSF biomarkers, baseline clinical features, and surgery outcome at 6 months.Results: Sixty (20.5%) iNPH patients showed alpha-synuclein seeding activity with no significant difference between cohorts. In contrast, the prevalence observed in CJD was only 6.7% (p= 0.002). Overall, 24.0% of iNPH participants showed an amyloid-positive (A+) status, indicating a brain co-pathology related to A beta deposition. At baseline, in the Italian cohort, a-synuclein RT-QuIC positivity was associated with higher scores on axial and upper limb rigidity (p=0.003 and p =0.011, respectively) and lower MMSEc scores (p =0.003). A+ patients showed lower scores on the MMSEc (p =0.037) than A- patients. Higher NfL levels were also associated with lower scores on the MMSEc (rho = -0.213; p= 0.021). There were no significant associations between CSF biomarkers and surgical outcome at 6 months (i.e. responders defined by decrease of 1 point on the mRankin scale).Conclusions: Prevalent LB- and AD-related neurodegenerative pathologies affect a significant proportion of iNPH patients and contribute to cognitive decline (both) and motor impairment (only LB pathology) but do not significantly influence the surgical outcome at 6 months. Their effect on the clinical benefit after surgery over a more extended period remains to be determined

Cerebrospinal fluid dynamics in idiopathic intracranial hypertension : a literature review and validation of contemporary findings

Publisher Copyright: © 2021, The Author(s).Background: Idiopathic intracranial hypertension (IIH) is a rare disease of unknown aetiology related possibly to disturbed cerebrospinal fluid (CSF) dynamics and characterised by elevated intracranial pressure (ICP) causing optic nerve atrophy if not timely treated. We studied CSF dynamics of the IIH patients based on the available literature and our well-defined cohort. Method: A literature review was performed from PubMed between 1980 and 2020 in compliance with the PRISMA guideline. Our study includes 59 patients with clinical, demographical, neuro-ophthalmological, radiological, outcome data, and lumbar CSF pressure measurements for suspicion of IIH; 39 patients had verified IIH while 20 patients did not according to Friedman’s criteria, hence referred to as symptomatic controls. Results: The literature review yielded 19 suitable studies; 452 IIH patients and 264 controls had undergone intraventricular or lumbar CSF pressure measurements. In our study, the mean CSF pressure, pulse amplitudes, power of respiratory waves (RESP), and the pressure constant (P0) were higher in IIH than symptomatic controls (p < 0.01). The mean CSF pressure was higher in IIH patients with psychiatric comorbidity than without (p < 0.05). In IIH patients without acetazolamide treatment, the RAP index and power of slow waves were also higher (p < 0.05). IIH patients with excess CSF around the optic nerves had lower relative pulse pressure coefficient (RPPC) and RESP than those without (p < 0.05). Conclusions: Our literature review revealed increased CSF pressure, resistance to CSF outflow and sagittal sinus pressure (SSP) as key findings in IIH. Our study confirmed significantly higher lumbar CSF pressure and increased CSF pressure waves and RAP index in IIH when excluding patients with acetazolamide treatment. In overall, the findings reflect decreased craniospinal compliance and potentially depleted cerebral autoregulation resulting from the increased CSF pressure in IIH. The increased slow waves in patients without acetazolamide may indicate issues in autoregulation, while increased P0 could reflect the increased SSP.Peer reviewe
