    Komplexa operationer i en komplex vårdform: om ledning, ledningsbehov och möjligheter till ledning för säkrare vård i hemmet2012Licentiate thesis, monograph (Other academic)
    Abstract [en]

    Advanced home care (ASIH) enables the patient to stay at home rather than to stay hospitalized in connection with severe medical conditions, while simultaneously this Thesis demonstrates that this is in fact not completely unproblematic and without risk. This partly because ASIH proves to be a complex form of care with many different kind of collaterally ongoing care contacts and efforts of care and concern, partly since ASIH concurrently can assume an overview over the treatment process and collaboration or cooperation between several treatment agents from different kinds of organizations and/or operations during all hours. This composes a relatively new heterogenetic and multifaceted context of care which to the professional practice means both new and less known problems within patient safety, which substantially can obstruct and rule out both the completion and the implementation of a safe home care.

    The Thesis is based upon an exploratory case study of problems within patient safety in correlation with an advanced home care, and where the research study has had its starting position in the professional practice with an interactive and qualitative research approach. The case study houses two part studies which show that the patient safety problems can be related to an intermediary and multi-organizational form of care, rather than an single operation. A command and control view upon the problems of patient safety, which the professional practice faces, show that missions within the frame of the care form ASIH can be regarded as either a complicated and not rarely a complex operation consistent with Alberts & Hayes (2007) and Brehmers (2008a; 2009c) terminology and where the assignments includes dynamic decision tasks. The case study reveals that the patient safety problems which concretely can obstruct and rule out the completion or implementation of the assignments in a safe way, can be considered related to the layout of the description of the assignments and also a lack of operative and tactical command and control level (of the handling and care of patients) in correlation with the different sorts of assignments that prevails – coincidentally as there is no suitable organization (forums of cooperation) and no appropriate IT-resources for the liaisons which effectively manages to promote and support the forms of cooperation that the character of the assignments also needs. The implicit system of conduct which comes forth through the analysis indicates that there is a need of improvement in order to enable effective command and control for a safer care, since the form of the system of conduct according to Brehmer´s (2006a,b; 2007a,b; 2008a,b; 2009c, 2010, 2011) model fails to satisfy the needs set by the function of command and control.

    The conclusion of the case study is that advanced home care should be regarded as an intermediary and multi-organizational care form which includes dynamic decision tasks and character wise complex operations contemplated per patient, thus demanding substantial command and control resources, a new point of view upon management and new auxiliary means of management in order to maintain a safe care during the implementation. The hypothesis which has been crystallized during the conclusions of the case study is that a more effective control and command and appropriate auxiliary means of command and control in real time, concerning primarily the handling of patients at the time of a change in care form, can improve the conditions of work in the professional practice and also result in more patient time, which consequently can be expected to contribute to concept of “Good care” i.g. cost effective, patient safe and dignified care.

    Concept design and In Vitro evaluation of a novel dynamic displacement Ventricular Assist Device2006Licentiate thesis, monograph (Other scientific)
    Abstract [en]

    Ventricular Assist Devices (VADs) are mechanical pumps used to off-load a deceased heart, primarily in late stage congestive heart failure patients. VAD employment may facilitate cardiac recovery, but most often provides time before a suitable heart transplant can be found. Lately, long term use VAD systems have been introduced as an alternative to a heart transplant.

    Traditionally, design of VADs has employed either displacement based pump technologies or radial-flow pumps, also known as rotodynamic pumps. A displacement pump induces a mechanical force on a fluid contained within a defined space, hence giving it motion. Radial-flow pumps impart momentum to a fluid, most often by placing a rotating device in the fluid.

    This thesis introduces a novel pumping concept, combining features from both displacement and radial-flow pumps. A first prototype, the VivicorTM pump, has been designed, fabricated and evaluated In Vitro, the results reported in this thesis.

    The In Vitro evaluation of the VivicorTM pump provides evidence of a pump with mechanical self-regulation based on pump pre-load level, much like a displacement pump. The VivicorTM pump also displays pulsating outflow in combination with an inflow both during pump systole and diastole. The latter provides potential advantages over traditional displacement pumps as smaller cannulae or catheters can be used, facilitating miniaturization. Continuos filling throughout the pumping cycle also require less pressure to be exerted on the fluid, compared to displacement pumps, limiting the risk of mechanical damage to the pumped fluid. The In Vitro evaluation has also provided further insights on necessary design modifications in the second-generation VivicorTM prototype, currently planned. The VivicorTM pumping technology is highly interesting for further development and evaluation for use in ventricular assist applications.

    Bostadsanpassningsbidraget i Sveriges kommuner: kostnadsvariation och handläggningsprocess2013Licentiate thesis, monograph (Other academic)
    Abstract [sv]

    En funktionsnedsättning beskrivs som nedsättning av fysisk, psykisk eller intellektuell funktionsförmåga. Ett funktionshinder är den begränsning som en funktionsnedsättning innebär för en person i relation till omgivningen. I Sverige är målet att möjliggöra för människor att leva så självständigt som möjligt i sitt eget hem. Lag (1992:1574) om bostadsanpassningsbidrag m. m., har utvecklats med det syftet. Kostnaden för bostadsanpassningsbidrag varierar kraftigt mellan Sveriges kommuner.Syftet med den här avhandlingen var att undersöka om dessa kostnadsvariationer kunde härledas till statistiskt mätbara kommunala bakgrundsfaktorer eller om de kunde relateras till arbetsprocessen i kommunen. Syftet var också att undersöka hur de som genom sitt arbete är berörda av bostadsanpassning tycker att handläggningsprocessen fungerar i praktiken.Studien delades in i tre delstudier. Första delstudien undersökte om kostnadsvariationerna för bostadsanpassningsbidraget kunde härledas till statistiskt mätbara kommunala variabler. Delstudie två genomfördes med en kvalitativ inriktning. Här valdes att studera hur personer, som på olika sätt är involverade i eller påverkas av processen kring bostadsanpassning, resonerar och arbetar. I delstudie tre var inriktningen att, utifrån tidigare delstudier, identifiera områden i bostadsanpassningsprocessen där det fanns utrymme för förbättringar. Delstudie tre utformades som en postenkät som skickades till närmare hundra bostadsföretag och ungefär lika många handläggare av bostadsanpassningsbidrag.I enlighet med tidigare studier var det svårt att finna några statistiskt mätbara kommunala bakgrundsvariabler som förklarade större delen av variationerna i kostnad för bostadsanpassning. Dock visade sig tre av variablerna ha ett statistiskt signifikant samband som till viss del förklarade skillnaderna. Dessa var andelen äldre, över 80 år, i befolkningen, kommunens resultat och prisutvecklingen på småhus i regionen under de senaste 20 åren. Långvarigt vänsterstyre ser enligt resultaten i denna studie ut att ha ett visst samband med högre kostnader för bostadsanpassning. Kommuner i norra Sverige hade med betydligt större sannolikhet höga kostnader för bostadsanpassning än låga. Ur resultatet i studien kan man utläsa att ”mjukare” faktorer som kommunkultur, människosyn och politiska ställningstaganden troligen är betydande i sammanhanget. Majoriteten av handläggarna som deltog i intervjustudien ansåg att handläggningsprocessen kring bostadsanpassning var för tidskrävande och att för tungt ansvar lades på den sökande. Handläggarna i kommunerna förenklade processen för att möta dessa två omständigheter. Det finns omfattande bristerna i dokumentationen kring ärendena.Fastighetsägarna uppger att den anpassning som de oftast nekar är åtgärder i badrum. Den huvudsakliga anledningen till att man nekar är risken för följdskador och att det är dyrt att återställa bostaden när den boende inte längre är i behov av anpassningen. Ett sätt att förbättra samarbetet mellan fastighetsägare och handläggare i kommuner där anpassningar ofta nekas, kan bland annat vara att ge fastighetsägarna bättre insyn i anpassningsprocessen och bättre kontroll över de åtgärder som genomförs i deras bestånd.
