Inledning En välsmakande och hygieniskt säker mat är viktig för patientens medicinska behandling och välbefinnande. Det ligger i sakens natur att man som patient ofta är svag eller nedsatt och därmed extra känslig för infektioner. Livsmedelshygien är på ett sjukhus en fråga om patientsäkerhet med temperaturen som den enskilt viktigaste faktorn. Brickdukning har som system för att distribuera maten inom ett sjukhus många fördelar men en nackdel är svårigheten att upprätthålla rätt temperatur. Mätningar på det studerade sjukhuset visade stora variationer och betydande avvikelser från tillåtna temperaturer, varför ett förbättringsprojekt genomfördes för att förbättra och stabilisera temperaturerna. Syfte Förbättringsarbetet studerades med syfte att beskriva de fenomen som den involverade personalen upplevt vara betydelsefulla för förbättringsarbetets resultat och hur patienternas upplevelse av maten förändrades under tiden för förbättringsarbetet. Syftet med förbättringsarbetet var att uppnå en stabil process med korrekta temperaturer. Metod Förbättringsarbetet genomfördes med PDSA-modellen som övergripande teori och metod. Studien utfördes som en deskriptiv fallstudie med induktiv ansats med deduktiva inslag. Fokusgruppsintervju och enkäter användes för datainsamling. Kvalitativ innehållsanalys och deskriptiv statistik användes som metoder vid analys. Resultat Förbättringsarbetet resulterade i betydande temperaturförbättringar, en stabil process med eftersträvade målvärden uppnåddes. Dock förändrades inriktning och mål för förbättringen under projekttiden, de ursprungliga målen uppnåddes ej till fullo. Förbättringarna minskade risken för matförgiftning bland patienterna. Studien visade att fenomen som i hög grad ligger inom mikrosystemets inflytande varit betydelsefulla. Dessa sammanfattades i fyra kategorier: Resursanvändning, Interaktion och kommunikation, Förändringsförmåga samt Delaktighet/engagemang. Slutsats Ett sjukhus med brickdukningssystem kan uppnå betydande förbättringar i mattemperaturen med hjälp av strukturerat förbättringsarbete. Förändringens resultat påverkades främst av fenomen som finns beskrivna i litteraturen sedan tidigare. Framtida studier kan med fördel kombinera induktiva, kvalitativa ansatser med deduktiva jämförelser med fenomen som finns beskrivna i litteraturen. / Introduction Tasty and hygienically safe food is essential to the treatment and comfort of the patient. Patients are commonly weak or impaired and more vulnerable to infections. Food hygiene is a matter of patient safety in hospitals where food temperature is the single most important factor. Meal tray as food distribution system in hospitals offers many advantages but one disadvantage is its ability to maintain proper temperature of the food. Measurements at the studied hospital display substantial variations and significant deviations from acceptable temperatures. Hence, an improvement project was completed in order to improve and stabilize temperatures. Purpose The improvement project was studied in order to describe what phenomena was important to the success for the improvement, according to staff involved and also how patients experience of the food. The aim of the improvement project was to achieve a stable process with proper food temperatures. Methods The quality improvement completed with the PDSA improvement model as overarching theory and method The study was conducted as a descriptive case study with an inductive approach and deductive ingredients. Focus group interview and questionnaires was used for data collection. Qualitative content analysis an descriptive statistics was used for analysis of data. Results The improvement project resulted in substantially temperature improvement, a stable process with desired temperatures was achieved. Yet the focus and the aims for the improvement were adjusted under the project period, the original aims were not achieved completely. The improved temperatures decreased the risk for patients getting infected with food poisoning. The study displayed phenomena that to a great extent are within the influence of the microsystem, as important for the success of the improvement. These where summarized in four categories: Utilization of resources, Interaction and communication, Improvement capability and Participation/involvement. Conclusions A hospital with meal tray distribution system can achieve substantial improvements in food temperature using structured improvement methods. The results of the changes were mainly affected by phenomena that already are described in the quality improvement litterature. Future studies may combine inductive, qualitative approaches with deductive comparisons to phenomena described in literature.

Main aim: To supply recommendations to implement a Hazard Analysis of Critical Control Points (HACCP) system in a hospital food service unit serving low bacterial diets in order to prevent or decrease the infection rates in Hematopoietic Stem Cell Transplant (HSCT) patients. Objectives: Firstly, to investigate the current food safety and hygiene status in a hospital food service unit, serving low bacterial diets, by means of a questionnaire and bacterial swabs taken from the food service unit. Secondly, to utilize the gathered information in a structured action plan to implement HACCP standards successfully in the appointed food service unit. The implementation of HACCP will not be done by the author. Design: The primary research was done in a food service unit of a 350 bed private hospital. One unsuspected audit with a pre-designed audit form was done. The audit consisted out of ten categories. A percentage was allocated to each category. Four swabs, as well as four food samples, were taken during the audit. The swabs and samples were tested to assess the microbiological safety of the foods prepared in the appointed hospital food service unit. The results of the audit, swabs and food samples were used to evaluate the current Food and Safety System of the hospital food service unit according to internationally approved HACCP standards. Setting: The study was conducted in the metropolitan area of Gauteng, South Africa. Results: None of the ten areas audited was of an acceptable standard and an average of 37% was scored. Category 5, the service and distribution area, scored the highest (69%) and category 10, the quality procedures and records division, scored the lowest (6%). According to United States Food and Drug Administration Baseline Report five forbidden policies could lead to increased risk of food borne illnesses. All five forbidden policies were detected in the food service unit during the audit. The microbiological tests showed relatively high microbial counts. Conclusion: The results of the study confirmed that instead of focusing mainly on the selection of food items allowed, and the cooking methods used in HSCT diets, the type of food service, together with the food and safety protocol that the food service follows, could play an important role in providing food that is safe for HSCT patient use. / Thesis (M.Sc.

Magister Scientiae (Nutrition Management) - MSc(NM) / Introduction: The significant link between mental health and nutrition throughout one’s life cannot be overstated. Yet this strong association is often neglected in the public healthcare sector in South Africa, particularly in the case of people who are being treated for various types of mental illness. It is therefore important to prioritise nutrition care through efficient and effective hospital food services in public psychiatric facilities. Although hospital settings are often perceived to provide efficient clinical care, the food provided to patients by hospital food service units is often criticised for being bland, repetitive and/or unhealthy. At times, too, inadequate food budget allocations by provincial health departments or poor supply chain management practices result in patients receiving inadequate quantities of food at mealtimes, which might lead to their becoming malnourished during their hospital stays. For psychiatric patients in particular, malnutrition can have serious short and longer-term consequences.

INTRODUÇÃO: Os trabalhadores dos Serviços de Nutrição Hospitalar são submetidos às exigências físicas, cognitivas e psíquicas que levam à distúrbios osteomusculares relacionados ao trabalho. O objetivo deste estudo foi implantar ações de melhorias nas situações de trabalho de um serviço de nutrição hospitalar e avaliar a percepção dos trabalhadores e as repercussões sobre os sintomas osteomusculares. MÉTODO: Esta pesquisa foi desenvolvida em um hospital público especializado em cardiologia, localizado em São Paulo, Brasil, após aprovação pelo comitê de ética da instituição. A coleta de dados foi realizada por meio da aplicação de questionários e análise ergonômica do trabalho. Os questionários continham dados sócio-demográficos, história ocupacional, situação de trabalho atual, sintomas osteomusculares e satisfação no trabalho. Do total de 130 trabalhadores, 115 participaram voluntariamente. A análise ergonômica do trabalho foi efetuada de acordo com Guérin et al (2001), sendo realizadas entrevistas, medições do ambiente da cozinha e análises biomecânicas. A partir dos resultados foram implantadas ações de intervenção baseadas na ergonomia participativa durante um ano. Após esta fase, 89 (77%) trabalhadores responderam novamente ao questionário, sendo incluídas perguntas sobre a percepção das modificações. A análise dos dados incluiu testes estatísticos para verificar se houve mudança da prevalência de sintomas antes e após as intervenções, com nível de significância de 5%, por meio dos Programas SPSS 13.0 e Excel 2003. Além disso, foram analisados os dados de percepção dos trabalhadores e dos especialistas em ergonomia sobre o impacto das melhorias na saúde e no processo de trabalho. RESULTADOS: A população constitui-se, em sua maioria, por mulheres, na faixa etária de 25 a 34 anos, com grau médio de escolaridade, casadas, com filhos, e ocupavam o cargo de atendente de nutrição. A maioria trabalhava de 5 a 10 anos no hospital e em jornada de trabalho de 40 horas semanais. Os principais problemas observados foram espaço físico reduzido, equipamentos e materiais de trabalho inadequados, absenteísmo e déficit de pessoal, volume excessivo de trabalho com elevado esforço mental, alta prevalência de sintomas osteomusculares, principalmente nos membros inferiores e ombros. Após as intervenções realizadas, houve melhoria na situação de trabalho com redução nos sintomas osteomusculares e os trabalhadores perceberam as seguintes mudanças nas situações de trabalho: melhoria na iluminação e no controle do ar condicionado, aquisição de batedeira de tamanho médio, conserto de equipamentos, substituição dos pratos de vidro por descartáveis, aquisição de cadeiras, introdução de pausas durante a jornada de trabalho, ginástica laboral e treinamento em liderança para as chefias. Neste período houve ampliação no número de leitos do hospital com conseqüente aumento no volume de trabalho e diminuição da satisfação no trabalho associados à crise financeira da instituição com suspensão de contratações e da compra de materiais e equipamentos. CONCLUSÕES: As intervenções repercutiram em melhorias, principalmente quanto ao ambiente e equipamentos, e na redução dos sintomas osteomusculares nos membros inferiores, ombros, pescoço/região cervical, antebraço e região lombar, apesar desta redução não ter sido estatisticamente significativa. / INTRODUCTION: Hospital food service workers have high level of physical, cognitive and mental demands that are associated with musculoskeletal disorders. The objective of this study was to introduce improvements in the working conditions in a hospital food service and to evaluate the workers perceptions and its effects on musculoskeletal symptoms. METHOD: this study was performed in a public cardiac hospital in São Paulo, Brazil, after its approval by the Ethics Committee. The data were collected by questionnaires and ergonomic analysis of the work. The questionnaire included: socio-demographic, workhistory, work conditions, musculoskeletal symptoms and job satisfaction. A hundred and fifteen questionnaries were applied from 130 workers. The work ergonomic analysis was carried out in accordance with Guérin et al (2001), by means of interviews, observations of kitchen working conditions and biomechanical analyses. Based on the results, interventions have been undertaken by means of a participatory ergonomic approach over one year. After this, another ergonomic analysis was carried out and 89 workers (77%) answered a new questionnaire that also included questions about their perception of the improvements. Data analysis was done by statistical tests to verify symptom prevalences before and after the interventions with a 5% level of significance. SPSS 13.0 and Excel 2003 software was used. RESULTS: The workers were women in the 25-34 age-group, had secondary education, were married, had children and occupied the position of nutrition attendants. They were in this hospital for from 5 to 10 years and on a 40 hour working week schedule. Most of problems observed were reduced space, inadequate equipment and work materials, absenteeism, insufficient number of workers, great volume of work with mental demands, high prevalence of musculoskeletal symptoms mainly in lower members and shoulders. After the improvements in working conditions, the symptoms of musculoskeletal disorders reduced and the workers perceived the following changes in the work process: better lighting and control of air conditioning, acquisition of low capacity mixer, repair of equipment, use of disposable utensils instead of glass plates, acquisition of more chairs, introduction of breaks during working hours, work related gymnastics, workshops for leadership training. In this period the number of hospital beds was increased with a corresponding intensification of the work load and a decline on job satisfaction. The hospital was in a financial crisis with consequences in terms of the hiring of personnel and the acquisition of equipment and materials. CONCLUSION: Interventions brought improvements mainly as regards the work environment and equipment and in the reduction of musculoskeletal symptoms in the lower members, shoulders, neck/cervical region, forearm and lumbar region, though this reduction has not been statistically significant.
