Self-help organisations: A qualitative study of successful collaboration with general practice

Thousands of self-help organisations (SHOs) exist in Australia but little is known about how they relate to the mainstream health care system. This qualitative study, based in south-east Queensland, aimed to identify examples of collaboration between general practitioners (GPs) and SHOs in order to examine the attributes of successful partnerships. Representatives of six SHOs, identified by key informants as having good collaborative links with GPs, and seven GPs with whom they collaborated, completed semi-structured interviews. The interviews focused on evidence of collaboration and perceptions of benefits and barriers experienced. Maximum variation sampling enabled a cross-section of SHOs in terms of size, funding, and health issue. Although GPs readily identified SHO benefits, they referred patients to them only rarely. SHO credibility, evidence of tangible benefits for patients, ease of contacting the SHO, and correspondence between the SHO?s focus and the GP?s personal and professional interests appear to contribute to the success of partnerships. We conclude that mutually beneficial partnerships between GPs and SHOs exist but are under-utilised. A more coordinated effort is needed to strengthen links between the two sectors.

A perspective on Australia's national medicines policy

There is international interest in Australia's health care system for prescription medicines. The issue is particularly topical in Canada with the debate following publication of the Romanow Report into the future of health care in Canada. This Report recommended a new National Drug Agency. Australia has a National Medicines Policy with four arms-quality, safety and efficacy of medicines; equity of access; a viable and responsible pharmaceutical industry; quality use of medicines. The four arms of the Policy are interlinked and interdependent for optimal functioning. In this paper, an overview of how the prescription drug system in Australia works is presented. The manuscript focuses upon specific aspects of the Policy, describing how it functions and some of the processes integral to success, from the viewpoint of the author. The discussion includes some of the advantages of Australia's system for pharmaceuticals as well as some of the problems, as these present opportunities for development and change

The psychoeducation needs of parents who have an adult son or daughter with a mental illness

Since deinstitutionalisation, parents of adults with mental disorders are increasingly utilised as a resource for their relatives’ care. This study used a general phenomenological perspective to capture people’s experiences. Semi-structured in-depth interviews were conducted with eight parents who were members of the Schizophrenia Fellowship of Southern Queensland to explore their perceptions of their psychoeducation needs. The themes that emerged included the usefulness of past experiences with psychoeducation, educational needs, barriers to accessing information and support, and other unmet carer needs, including the need for managing stress and emotional needs, recognition and inclusion of family members in decision-making, and negotiating the best care for their family member within the health care system. This study adds to an increasing body of knowledge that advocates for the greater inclusion and involvement of families in the care and treatment of their relatives. Further research into the needs of families, in particular barriers and supports in accessing information and services, is recommended.

A cost-effectiveness analysis of two rehabilitation support services for women with breast cancer

The purpose of this research was to estimate the cost-effectiveness of two rehabilitation interventions for breast cancer survivors, each compared to a population-based, non-intervention group (n = 208). The two services included an early home-based physiotherapy intervention (DAART, n = 36) and a group-based exercise and psychosocial intervention (STRETCH, n = 31). A societal perspective was taken and costs were included as those incurred by the health care system, the survivors and community. Health outcomes included: (a) 'rehabilitated cases' based on changes in health-related quality of life between 6 and 12 months post-diagnosis, using the Functional Assessment of Cancer Therapy - Breast Cancer plus Arm Morbidity (FACT-B+4) questionnaire, and (b) quality-adjusted life years (QALYs) using utility scores from the Subjective Health Estimation (SHE) scale. Data were collected using self-reported questionnaires, medical records and program budgets. A Monte-Carlo modelling approach was used to test for uncertainty in cost and outcome estimates. The proportion of rehabilitated cases was similar across the three groups. From a societal perspective compared with the non-intervention group, the DAART intervention appeared to be the most efficient option with an incremental cost of $1344 per QALY gained, whereas the incremental cost per QALY gained from the STRETCH program was $14,478. Both DAART and STRETCH are low-cost, low-technological health promoting programs representing excellent public health investments.

Patient self-efficacy and health locus of control: relationships with health status and arthritis-related expenditure

Objective. To explore the relationship between measures of self-efficacy, health locus of control, health status and direct medical expenditure among community-dwelling subjects with rheumatoid arthritis (RA) and osteoarthritis (OA). Methods. This analysis is part of a larger ongoing study of the costs and outcomes of arthritis and its treatments. Community-dwelling RA and OA respondents completed questionnaires concerning arthritis-related expenditure, health status, arthritis related self-efficacy and health locus of control. Results. Data were obtained from 70 RA respondents and 223 OA respondents. The majority of respondents were female with a mean age of 63 yr for RA respondents and 68 yr for OA respondents. Among the RA respondents, those with higher self-efficacy reported better health status and lower overall costs. Health locus of control was not consistently correlated with health status. OA respondents with higher self-efficacy reported better health status and lower costs. Health locus of control had more influence. OA respondents with higher external locus of control reported worse pain and function. A higher belief in chance as a determinant of health was correlated with more visits to general practitioners and a higher cost to both the respondent and the health system. Conclusion. Higher self-efficacy, which is amenable to change through education programmes, was associated with better health status and lower costs to the respondent and the health system in this cross-sectional study. Locus of control had less of an influence; however, the tendency was for those with higher external locus of control to have higher costs and worse health status. As the measurement of these constructs is simple and the outcome potentially affects health status, these results have implications for future intervention studies to improve quality of life and reduce the financial impact of arthritis on both the health-care system and patients.

Error recovery in a hospital pharmacy

A field study was performed in a hospital pharmacy aimed at identifying positive and negative influences on the process of detection of and further recovery from initial errors or other failures, thus avoiding negative consequences. Confidential reports and follow-up interviews provided data on 31 near-miss incidents involving such recovery processes. Analysis revealed that organizational culture with regard to following procedures needed reinforcement, that some procedures could be improved, that building in extra checks was worthwhile and that supporting unplanned recovery was essential for problems not covered by procedures. Guidance is given on how performance in recovery could be measured. A case is made for supporting recovery as an addition to prevention-based safety methods.

General practice in Australia 2020: "robust and ready" or "rudderless and reeling"?

The future role and structure of Australian general practice remains uncertain, despite a decade of seemingly constant change following the release of the National Health Strategy papers. Some of the suggested change strategies (such as rural Practice Incentive Payments and practice accreditation) have been implemented; others (such as general practitioner involvement with area health authorities in delivering national goals and targets for communities) still await attention. An overarching vision for our health care system in 2020 and general practice's role within it are still to be clearly enunciated. Australia is at variance with other Western countries, such as the United Kingdom, Canada and New Zealand, which have spent significant time refocusing their health systems to deal with an ageing population with an increased burden of chronic disease. Health bureaucrats and governments need to invest strategically in operational primary care now. This will require the active commitment of general practice's national bodies to articulate and actively promote a shared vision for Australian general practice.

Structural and cellular characterization of Idiopathic Pulmonary Fibrosis

La Fibrosi Polmonare Idiopatica (IPF) è una malattia polmonare cronica, irreversibile la cui eziologia risulta essere ignota, caratterizzata da un processo fibrotico progressivo che inizia nel tratto respiratorio inferiore. Le persone affette da IPF presentano età media compresa tra 55 e 77 anni. L’incidenza annuale di IPF è stata recentemente stimata tra 14 e 42,7 casi per 100.000 persone e tale dato risulta essere in aumento. IPF fa parte delle malattie Polmonari Idiopatiche Interstiziali (IIP) che comprendono patologie con quadri istologici e clinici differenti. Le affezioni su cui si concentrerà questo studio sono: UIP (Usual Interstitial Pneumonia) caratterizzata da fibrosi interstiziale e dalla presenza di foci fibrotici connessi alla pleura e corrispondente al quadro anatomopatologico della maggior parte dei casi di IPF; NSIP (Non Specific Interstitial Pneumonia) simile alla UIP ma con maggiore uniformità temporale e spaziale delle manifestazioni; Sarcoidosi, malattia granulomatosa ad eziologia ignota. Attualmente la gravità della IPF, che implica una mortalità del 50% dei pazienti a 5 anni dall’esordio, e la scarsa efficacia farmacologica nel rallentarne la progressione vedono il trapianto polmonare come unica possibilità di sopravvivenza nelle forme più severe. Al momento non è chiaro il meccanismo patogenetico di insorgenza e progressione della IPF anche se sono stati individuati alcuni fattori scatenanti quali fumo di sigaretta, infezioni respiratorie e inquinanti atmosferici; tuttavia nessuno di tali elementi può da solo determinare un così esteso e progressivo rimodellamento del parenchima polmonare. Numerose sono le evidenze di come il substrato genetico, le alterazioni del rapporto morte/proliferazione cellulare e le citochine svolgano un ruolo nella genesi e nella progressione della malattia, ma non sono ancora chiari i fenomeni biologico-cellulari che la sostengono e, quindi, quali siano i punti di attacco per poter incidere terapeuticamente nel modificare l’evoluzione della IPF. Poiché il nostro laboratorio ha partecipato alla scoperta dell’esistenza di cellule staminali nel polmone umano normale, uno degli obiettivi finali di questo progetto si basa sull’ipotesi che un’alterazione del compartimento staminale svolga un ruolo cruciale nella eziopatogenesi di IPF. Per questo in precedenti esperienze abbiamo cercato di identificare nella IPF cellule che esprimessero antigeni associati a staminalità quali c-kit, CD34 e CD133. Questo lavoro di tesi si è proposto di condurre un’indagine morfometrica ed immunoistochimica su biopsie polmonari provenienti da 9 pazienti affetti da UIP, 3 da NSIP e 5 da Sarcoidosi al fine di valutare le alterazioni strutturali principali imputabili alle patologie. Preparati istologici di 8 polmoni di controllo sono stati usati come confronto. Come atteso, è stato osservato nelle tre patologie esaminate (UIP, NSIP e Sarcoidosi) un significativo incremento nella sostituzione del parenchima polmonare con tessuto fibrotico ed un ispessimento dei setti alveolari rispetto ai campioni di controllo. L’analisi dei diversi pattern di fibrosi presenti fa emergere come vi sia una netta differenza tra le patologie con una maggiore presenza di fibrosi di tipo riparativo e quindi altamente cellulata nei casi di UIP, e NSIP mentre nelle Sarcoidosi il pattern maggiormente rappresentato è risultato essere quello della fibrosi replacement o sostitutiva. La quantificazione delle strutture vascolari è stata effettuata tenendo separate le aree di polmone alveolare rispetto a quelle occupate da focolai sostitutivi di danno (componente fibrotica). Nei campioni patologici analizzati era presente un significativo riarrangiamento di capillari, arteriole e venule rispetto al polmone di controllo, fenomeno principalmente riscontrato nel parenchima fibrotico. Tali modifiche erano maggiormente presenti nei casi di NSIP da noi analizzati. Inoltre le arteriole subivano una diminuzione di calibro ed un aumento dello spessore in special modo nei polmoni ottenuti da pazienti affetti da Sarcoidosi. Rispetto ai controlli, nella UIP e nella Sarcoidosi i vasi linfatici risultavano inalterati nell’area alveolare mentre aumentavano nelle aree di estesa fibrosi; quadro differente si osservava nella NSIP dove le strutture linfatiche aumentavano in entrambe le componenti strutturali. Mediante indagini immunoistochimiche è stata documentata la presenza e distribuzione dei miofibroblasti, positivi per actina muscolare liscia e vimentina, che rappresentano un importante componente del danno tissutale nella IPF. La quantificazione di questo particolare fenotipo è attualmente in corso. Abbiamo inoltre analizzato tramite immunoistochimica la componente immunitaria presente nei campioni polmonari attraverso la documentazione dei linfociti T totali che esprimono CD3, andando poi a identificare la sottopopolazione di T citotossici esprimenti la glicoproteina CD8. La popolazione linfocitaria CD3pos risultava notevolmente aumentata nelle tre patologie analizzate soprattutto nei casi di UIP e Sarcoidosi sebbene l`analisi della loro distribuzione tra i vari distretti tissutali risultasse differente. Risultati simili si sono ottenuti per l`analisi dei linfociti CD8pos. La componente monocito-macrofagica è stata invece identificata tramite la glicoproteina CD68 che ha messo in evidenza una maggiore presenza di cellule positive nella Sarcoidosi e nella UIP rispetto ai casi di NSIP. I dati preliminari di questo studio indicano che il rimodellamento strutturale emo-linfatico e cellulare infiammatorio nella UIP si differenziano rispetto alle altre malattie interstiziali del polmone, avanzando l’ipotesi che il microambiente vascolare ed immunitario giochino un ruolo importante nella patogenesi della malattia

Experiences of patients with age-related macular degeneration receiving anti-vascular endothelial growth factor therapy:a qualitative study

The societal cost for the average health authority in the United Kingdom for the care of wet age-related macular degeneration (AMD) has been suggested to be around £7.4 million. It is vital that the best possible care based on the best available evidence is provided to reduce the impact of AMD on patients' lives and the financial cost to the health-care system. This study explored the experiences of AMD patients treated with intravitreal ranibizumab injections. Three semistructured interviews were conducted with seven participants over the course of 18 months. Transcripts were analysed using interpretative phenomenological analysis. Analysis identified four themes: preparing for treatment, the treatment process, patient-provider communication, and results of treatment. Patient experiences highlighted the need to move away from the reliance on letters for information provision, and the need for clearer guidelines about when to cease AMD treatment. Interviews highlighted the need for the inclusion of rigorous qualitative evidence with experiential data in future good clinical practice guideline development for AMD. © The Author(s) 2013.

Psychotic symptoms are associated with physical health problems independently of a mental disorder diagnosis:results from the WHO World Health Survey

This study explored whether physical health problems are related to psychotic symptoms independently of a mental disorder diagnosis. A total of 224,254 subjects recruited for the World Health Organization World Health Survey were subdivided into those with both a lifetime diagnosis of psychosis and at least one psychotic symptom in the 12 months prior to the evaluation, those with at least one psychotic symptom in the past 12 months but no lifetime diagnosis of psychosis, and those without psychotic symptoms in the past 12 months and without a lifetime diagnosis of psychosis. The three groups were compared for the presence of medical conditions, health problems, and access to health care. Medical conditions and health problems (angina, asthma, arthritis, tuberculosis, vision or hearing problems, mouth/teeth problems, alcohol consumption, smoking, and accidents), medication consumption, and hospital admissions (but not regular health care visits) were more frequent in individuals with psychotic symptoms but no psychosis diagnosis, compared to those with no symptoms and no diagnosis. The number of medical conditions increased with the number of psychotic symptoms. Given the sample analyzed, this trend seems to be independent from the socio-economic development of the country or the specific health care system.

Egészségügyi reform Horvátországban (Health reform in Croatia)

A horvátországi egészségügyi reform célja a decentralizáció elvén alapuló egészségügyi rendszer létrehozása volt. Az egészségügyi szolgáltatások költségnövekedése által okozott terheket a központi költségvetés helyett egyre nagyobb mértékben a lakosság viseli, miközben kiegészítő biztosítás létrehozásával megkísérelték csökkenteni a változások nemkívánatos következményeit. A gyógyszer-finanszírozási rendszer átalakításával a költségcsökkentés mellett el akarták érni, hogy a betegek nagyobb arányban jussanak hozzá a modern, innovatív gyógyszerekhez. ________ The Croatian health care system faced great challenges during the1990s. The aim of the paper is to review some important aspects of the Croatian health care reform. Establishing a decentralized health care system was an important section of the reform. As a new element of the health insurance system, burdens generated by the increase of costs of health services have fallen on the society increasingly, while complementary health insurance tried to decrease the undesirable consequences of the changes. The objective of the drug-financing reform was to reduce the costs and improve access to innovative medicines as well. As regards the success of the reforms, besides increasing incomings, the method and result of the spending of the health insurance funds is crucial.

Nursing curriculum: Changing students' knowledge and biases towards older adults

Caring for the older adult is a topic debated and discussed at all levels of today's society. Nurses are expected to educate patients and family members about their medications and care following hospitalization or contact with the health care system. The majority of these patients are elderly. The purpose of the study was to determine if a course on aging would affect the knowledge and biases of nursing students in a Baccalaureate nursing program at a Southeast Florida University. Nursing students (N = 52) were surveyed at the beginning of the semester using Palmore's Facts on Aging Quiz that is structured to determine the knowledge and biases of individuals towards the older adult. Students were surveyed before and after the nursing course that had a didactic and clinical component in the hospital setting. Analysis of the data by Chi square and repeated measure ANOVA supported the hypothesis that a course segment on aging would affect the knowledge level of the nursing students and result in changes of their biases toward the older adult. ^

The relationship between spirituality, knowledge and tuberculosis (TB) medication adherence among African Americans and Haitians

Tuberculosis (TB) is an infectious disease and nonadherence to medication can lead to new cases, multi-drug resistant TB, or potential death. Additionally, healthcare professionals and individuals with TB’s knowledge of the disease and medication adherence are crucial for successful completion of medication therapy. Patient education is one of the most important aspects of care provided in healthcare settings (CDC, 1994). TB tends to disproportionately affect minority and economically disadvantaged patient populations. The purpose of this mixed method study was to explore the relationship between spirituality, knowledge, and TB medication adherence among African Americans and Haitians. The primary research question was: What is the relationship between spirituality, knowledge and TB medication adherence among African Americans and Haitians? Quantitative data were gathered from 33 questionnaires and analyzed by two ANOVAs and four chi square analyses. The null hypothesis was not rejected; there was not a statistically significant relationship between spirituality and TB medication adherence (p =.208) among the study’s African Americans and Haitians. Qualitative data concerning participants’ knowledge of TB, gathered from 16 individual interviews further informed this analysis. Secondary research questions examined the role of spirituality, knowledge of TB and medication adherence among African Americans and Haitians. Four common themes emerged across both groups to answer the secondary research questions. Interviews revealed the themes: (a) God is in control, (b) stigmatization of TB, (c) lack of knowledge, and (d) fear of death. The theme lack of knowledge about TB was found to contribute to stigmatization of TB patients. However, in this study stigma and lack of knowledge were related to initial denial of symptoms and delayed diagnosis, but not found to be related to TB medication adherence. This study could help adult educators and health educators enhance their educational interventions, develop a better understanding of adult learning, resulting in early diagnosis and treatment ultimately decreasing transmission of TB, drug resistance, and potential death. Educators should be aware that TB patients’ spirituality may be an important part of how they cope with having TB. A larger scale study, conducted at multiple locations should be conducted to extend the findings of this small scale exploratory study. Further studies should be done to better determine what patient, healthcare provider and health care system factors might mediate relationships that may exist between lack of knowledge of TB, stigma and TB medication adherence.
