Exploring the development of Australian general practice nursing: where we have come from and where to from here?

Significant development has occurred in the role and scope of Australian general practice nursing in the last decade. Although there has been a nursing presence in Australian general practice for many years (Linn 1977), current workforce shortages and the growing need for chronic and complex disease management and provision of preventive health care in the community have fuelled role development (Halcomb, Patterson & Davidson 2006). In an effort to explore and document the evolution of scholarship and professional development in Australian general practice nursing a content analysis of the proceedings of the four Australian practice nursing conferences was undertaken.This framework allows the mapping of the trajectory related to professional development issues, policy, research and scholarship. Content analysis revealed that the papers presented at each of the four conferences could be broadly divided into six major themes, namely: (1) role of the practice nurse, (2) education and training, (3) research, (4) legal, ethical and risk issues, (5) innovation in clinical practice, and (6) operational and management issues in general practice. Documenting the evolution of this emerging specialty is important in planning initiatives to maximise practice nurses' important contribution to primary health care.     

Which general intensive care unit patients can benefit from placement of the pulmonary artery catheter?

From the report by Connors and coworkers in 1996 until now, much effort has been directed at demonstrating the safety and/or effectiveness of strategies based on pulmonary artery catheter (PAC) data. Although studies have failed to demonstrate a clear benefit of PAC use, neither have any corroborated the initial report of PAC-induced mortality. With this in mind, it is important to clarify the indications for PAC, taking into account the development of new technologies to measure cardiac output and stroke volume. The present review focuses on safety and effectiveness data, with a special focus on reasonable indications for PAC use in the intensive care unit. The PAC has evolved since its initial presentation, and it now offers numerous parameters in addition to cardiac output and pressure measurement, such as mixed oxygen saturation and right ventricular ejection fraction. Because many techniques may be used to measure cardiac output, the indications for PAC use have become founded on other parameters that are useful in more specific situations, essentially involving the right circulation.     

Continuity of care in the transition from emergency department to general practitioner: Is it adequate?

Objective : To assess the adequacy of continuity of care for patients who are discharged to home or admitted to hospital from the emergency department. Methods : Questionnaire survey of emergency department communication practices. Results : Seventy-five of 86 emergency departments (87.2%) participated. Emergency departments failed to communicate with general practitioners upon disposition of many patients. For patients discharged to home, significantly more private emergency departments contacted general practitioners directly by telephone (P < 0.01) or by letter (P < 0.001). Significantly more public emergency departments gave patients a letter to take to their general practitioners (P < 0.01). Overall, emergency departments gave the patient a general practitioner letter some (33.3% of emergency department) or most (40.0%) of the time. Few letters were posted or faxed and little use of Email was made. Pre-formatted letters were used less than was expected. On patient admission, the telephone was used most frequently to advise general practitioners. Conclusions : Continuity of patient care may be inadequate in many emergency departments. Emergency departments should establish a check system to ensure that a communication is made with the general practitioners of all patients. Telephone or facsimile communication is recommended on patient admission. Other modes may be more appropriate on patient discharge to home. Structured, pre-formatted letters/facsimiles are recommended. Emergency department–general practitioner communications should be used as a performance indicator of emergency department practice.     

Perimenstrual migraines: Are they different from migraines in general?

Differences between menstrually related migraine (MRM) and non-MRM are subtle. Preconception that population-based trials do not show differences, but that clinic-based trials showed severe, longer, and clinically refractory menstrual migraines, turns out to be simplistic. This review examines studies comparing and contrasting MRM and non-MRM. All of the pertinent studies show increase of migraine around menses. A judicious reading of the studies suggests that MRM is probably more severe in pain intensity than non-MRM. MRM is more disabling than non-MRM. MRM in clinics is more likely to have both worse prodrome and nausea. A significant subset of MRM patients has poorer response to acute medication. Overall, it appears that MRM is more severe than non-MRM when considering population-and clinic-based studies, with slightly but clinically meaningfully worse intensity, duration, disability, prodrome, nausea, and response to acute medications. Clinicians must have compassion and skill to manage patients with MRM.     

Are we not over-estimating the prevalence of coeliac disease in the general population?

Until the 1980s, coeliac disease was considered to be a rare disease, but in the 1990s it became clear that it was a frequent condition. Recently, it was suggested to affect 1 out of 100 subjects in the Western world. To understand what the true prevalence of coeliac disease is in the general population, we conducted a systematic review of published papers. The overall prevalence of coeliac disease in the general population appears to be around 1/160 (6.2‰), but this figure varies widely according to the diagnostic criteria used in the original papers. Prevalence obtained with tissue transglutaminase antibodies only was markedly higher than that obtained through a histological diagnosis. We conclude that the prevalence of coeliac disease in the general population has been over-estimated. This is mainly due to tissue transglutaminase antibodies being used as the only diagnostic tool.     

Inpatient care: should the general physician now take charge?

In an ageing population, patients are living longer with one or more chronic disease, and with acute illnesses increasingly extending outside the boundaries of a single medical specialty. Therefore, is it time for the general physician to take charge?
