The journal is normally published twice a year; each individual issue covers a specific theme and is edited by one or more guest editors. The guest editors invite prospective authors to submit articles within the specific theme, unsolicited articles are generally not accepted. The main aims for the thematic issues are to provide comprehensive scientific overviews of the specific fields, and of the work going on within these fields in Norway, and partly in other countries. The Board of NOFE approves the themes for the specific issues, and appoints guest editors. All members of NOFE can suggest topics and editors.</p> <p>The Norwegian Journal of Epidemiology is open access, and can be downloaded freely from this website. There is no submission or page charges for manuscripts accepted for publication. The Norwegian Journal of Epidemiology is double-blind peer reviewed and the journal is listed level 1 in the <a href="https://dbh.nsd.uib.no/publiseringskanaler/KanalTidsskriftInfo.action?id=339899&bibsys=false&request_locale=en">Norwegian scientific classification system</a>.</p>https://www.ntnu.no/ojs/index.php/norepid/article/view/5639Full Issue 1-2(2023)2023-10-23T07:08:04+00:00- -katherine.fonn@ntnu.no<p>-</p>2023-10-20T00:00:00+00:00Copyright (c) 2023 https://www.ntnu.no/ojs/index.php/norepid/article/view/5601Innhold2023-10-06T11:05:43+00:00- -katherine.fonn@ntnu.no<p>--</p>2023-10-20T00:00:00+00:00Copyright (c) 2023 - -https://www.ntnu.no/ojs/index.php/norepid/article/view/5602Forord2023-10-06T11:16:25+00:00Eva Stenslandkatherine.fonn@ntnu.no<p><span style="color: rgba(0, 0, 0, 0.87); font-family: 'Noto Sans', -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen-Sans, Ubuntu, Cantarell, 'Helvetica Neue', sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;">Eva Stensland<br />Senter for klinisk dokumentasjon og evaluering (SKDE)<br />Helse Nord RHF</span></p>2023-10-20T00:00:00+00:00Copyright (c) 2023 Eva Stenslandhttps://www.ntnu.no/ojs/index.php/norepid/article/view/5603Medisinske kvalitetsregistere i Norge 2023-10-06T11:21:03+00:00Eva Stensland eva.stensland@helse-nord.noPhilip Skaueva.stensland@helse-nord.no<p>-</p>2023-10-20T00:00:00+00:00Copyright (c) 2023 Eva Stensland , Philip Skauhttps://www.ntnu.no/ojs/index.php/norepid/article/view/5604MS-registeret: meget viktig for MS-pasientene og enda viktigere fremover2023-10-06T11:25:00+00:00Jan Anders Istad katherine.fonn@ntnu.noMagne Wang Fredriksenkatherine.fonn@ntnu.no<p>-</p>2023-10-20T00:00:00+00:00Copyright (c) 2023 Jan Anders Istad , Magne Wang Fredriksenhttps://www.ntnu.no/ojs/index.php/norepid/article/view/5605Et lederperspektiv – nytten av medisinske kvalitetsregistre og hvordan vi bruker disse i forbedringsarbeid og praksisendring2023-10-06T11:29:39+00:00Bjørn Egil Vikse katherine.fonn@ntnu.noPanchakulasingam Kandiahkatherine.fonn@ntnu.no<p>-</p>2023-10-20T00:00:00+00:00Copyright (c) 2023 Bjørn Egil Vikse , Panchakulasingam Kandiahhttps://www.ntnu.no/ojs/index.php/norepid/article/view/5606The impact of longitudinal surveillance of individuals with cerebral palsy in Norway; a 20-year quality registry and follow-up program perspective2023-10-06T11:32:57+00:00Sandra Julsen Hollungsandra.julsen.hollung@siv.noReidun Jahnsensandra.julsen.hollung@siv.noGunvor Lilleholt Klevbergsandra.julsen.hollung@siv.noNina Kløve sandra.julsen.hollung@siv.noGuro L. Andersensandra.julsen.hollung@siv.no<p>ABSTRACT<br />The Norwegian Quality and Surveillance Registry for Cerebral Palsy (NorCP) has systematically collected<br />data on individuals with cerebral palsy (CP) and been a driver of knowledge dissemination for over 20 years.<br />NorCP data have increased the competence of health professionals in both the municipal and specialist<br />healthcare services through publication of multiple scientific articles ranging from risk factors for CP to<br />lifelong interventions, quality improvement projects, and training services. This has led to a streamlined<br />process in the diagnosis and follow-up of children and youths with CP in Norway to ensure that they receive<br />"the right treatment at the right time," regardless of where they live using evidence-based interventions based<br />on needs that are revealed in the registrations.<br />NORSK SAMMENDRAG<br />Norsk kvalitets- og oppfølgingsregister for cerebral parese (NorCP) har systematisk samlet inn data om<br />personer med cerebral parese og vært en pådriver for kunnskapsformidling i over 20 år. NorCP data har økt<br />kompetansen til helsepersonell i både kommune- og spesialisthelsetjenesten gjennom publisering av flere<br />vitenskapelige artikler om risikofaktorer for CP til livslange intervensjoner, kvalitetsforbedringsprosjekter<br />samt kurs og kompetansetjenester. Dette har ført til økt kvalitet på diagnostisering og oppfølging av barn og<br />unge med CP i Norge, som sikrer at de får «riktig behandling til rett tid», uansett hvor de bor i landet med<br />bruk av evidensbaserte intervensjoner basert på behov som avdekkes ved registreringene.</p>2023-10-20T00:00:00+00:00Copyright (c) 2023 Sandra Julsen Hollung, Reidun Jahnsen, Gunvor Lilleholt Klevberg, Nina Kløve , Guro L.

Registerets hovedmål er å sikre kvalitet og enhetlig diagnostikk, behandling<br />og oppfølging av pasientgruppen. Dette gjøres ved å samle inn kliniske data, gjennomføre kvalitetsforbedring<br />av behandlingstilbudet og drive forskning på årsaksforhold og sykdomsmekanismer ved å kombinere<br />registerdata og biobankmateriale. Registeret har i løpet av de første fire årene med datainnsamling møtt på<br />en rekke utfordringer knyttet til koronapandemi og ressursknapphet i helsetjenesten. Flere tiltak har blitt<br />gjennomført for å løse dette og vi ser nå tydelig effekt av disse. Ved utgangen av 2022 hadde registeret en<br />dekningsgrad på nesten 22 %.<br />ENGLISH SUMMARY<br />The Norwegian Parkinson’s Registry and Biobank was granted status as a National Quality Registry by the<br />Norwegian Directorate of Health in 2016 and startet registration of patients with Parkinson’s disease and<br />atypical neurodegenerative parkinsonism in December 2018. The main aim of the registry is to ensure quality<br />and uniform diagnostics, treatment and follow-up of the patient group by collecting clinical data, implementing<br />quality offers of treatment and conducting research into causal relationships and disease mechanisms by<br />combining registry data and biobank material. During the first four years of data collection, the Parkinson’s<br />Registry has encountered a number of challenges related to coronavirus pandemic and resource scarcity in<br />the health service. Several measures have been implemented to solve these challenges, and we are now<br />starting to see the effect of these measures. At the end of 2022, a coverage rate of nearly 22 % was achieved. </p>2023-10-20T00:00:00+00:00Copyright (c) 2023 Kenn Freddy Pedersen, Johannes Lange , Eldbjørg Fiskehttps://www.ntnu.no/ojs/index.php/norepid/article/view/5612Realizing the potentials of a National Spinal Cord Injury Registry – 10 years of experiences2023-10-06T11:59:22+00:00 Annette Halvorsenannette.halvorsen@stolav.noAnn Louise Pettersenannette.halvorsen@stolav.noSara Rise Langloannette.halvorsen@stolav.no Horn Siv Anitaannette.halvorsen@stolav.no Rekand Tiinaannette.halvorsen@stolav.no<p>The Norwegian Spinal Cord Injury Registry is a national quality registry that just celebrated its 10-year anniversary.

To aid the interpretation of quality indicators and support decisions, it is important<br />to quantify the uncertainty around the QI summary statistics. In this paper we suggest a novel method for<br />quantifying such uncertainty: the Coverage uncertainty range. The method is based on the size of the<br />population present in the register relative to the total relevant population and does not make any assumptions<br />about the sampling strategy or the value of the summary statistic. Furthermore, using both simulated data<br />and real-life data from a Norwegian medical quality registry, we illustrate why using confidence intervals<br />when presenting healthcare quality indicators may lead to erroneous conclusions.</p>2023-10-20T00:00:00+00:00Copyright (c) 2023 Kari Krizak Halle, Tormod Aarlott Digre, Ragna Elise Støre , Torunn Varmdalhttps://www.ntnu.no/ojs/index.php/norepid/article/view/5618 External validation of SAPS II score reported to the Norwegian Intensive Care and Pandemic Registry (NIPaR)2023-10-06T13:23:30+00:00Eirik Alnes Buaneseirik.alnes.buanes@helse-bergen.noØyvind Bruserudeirik.alnes.buanes@helse-bergen.noSergio Carracedo Hurozeirik.alnes.buanes@helse-bergen.noAndreas Barratt-Dueeirik.alnes.buanes@helse-bergen.noHans Flaatteneirik.alnes.buanes@helse-bergen.noReidar Kvåleeirik.alnes.buanes@helse-bergen.no<p>Background: Simplified Acute Physiology Score II (SAPS II) is a mortality prediction model widely used<br />to compensate for differences between intensive care units (ICU) in benchmarking and research. Accuracy<br />of SAPS II is sparsely documented. We investigate accuracy by comparing patient journal SAPS II values<br />with registry SAPS II values in the Norwegian Intensive Care and Pandemic Registry (NIPaR).<br />Method: NIPaR personnel collected data from the patient journal during visitations to ICUs in ten different<br />hospitals between 2017 and 2022 while blinded for registry SAPS II data. The patient journal SAPS II values<br />were subsequently compared with the registry SAPS II values.<br />Results: Difference of means for SAPS II score between patient journal and registry data was 5.2 points<br />(95% CI 2.8–7.6; p < 0.001). SAPS II score depended significantly on ICU (p < 0.001) and data origin (p =<br />0.006), whereas the interaction term for these two variables was not significant.<br />Conclusion: We find low accuracy of SAPS II score in a registry setting.</p>2023-10-20T00:00:00+00:00Copyright (c) 2023 Eirik Alnes Buanes, Øyvind Bruserud, Sergio Carracedo Hurozhttps://www.ntnu.no/ojs/index.php/norepid/article/view/5619Medisinsk koding til besvær 2023-10-06T13:27:50+00:00Marianne Aardal Grytaasmarianne.grytaas@helse-bergen.noLars Breivikmarianne.grytaas@helse-bergen.no Anders Palmstrøm Jørgensenmarianne.grytaas@helse-bergen.noTrine Elisabeth Finnesmarianne.grytaas@helse-bergen.noLena Adriana Denstad Skavlanmarianne.grytaas@helse-bergen.noRobert Wiikmarianne.grytaas@helse-bergen.noKnut Ivar Johansenmarianne.grytaas@helse-bergen.noEystein Sverre Husebyemarianne.grytaas@helse-bergen.no<p>The following paper is reprinted with permission from Tidsskrift for Den norske legeforening</p> <p>Publisert: 7. oktober 2020.
