Persistent problems 1 year after mild traumatic brain injury: a longitudinal population study in New Zealand

BACKGROUND Mild traumatic brain injury (mTBI) is a common problem in general practice settings, yet previous research does not take into account those who do not attend hospital after injury. This is important as there is evidence that effects may be far from mild. AIM To determine whether people sustain any persistent effects 1 year after mTBI, and to identify the predictors of health outcomes. DESIGN AND SETTING A community-based, longitudinal population study of an mTBI incidence cohort (n = 341) from a mixed urban and rural region (Hamilton and Waikato Districts) of the North Island of New Zealand (NZ). METHOD Adults (>16 years) completed assessments of cognitive functioning, global functioning, post-concussion symptoms, mood, and quality of life over the year after injury. RESULTS Nearly half of participants (47.9%) reported experiencing four or more post-concussion symptoms 1 year post-injury. Additionally, 10.9% of participants revealed very low cognitive functioning. Levels of anxiety, depression, or reduced quality of life were comparable with the general population. Having at least one comorbidity, history of brain injury, living alone, non-white ethnic group, alcohol and medication use, and being female were significant predictors of poorer outcomes at 12 months. CONCLUSION Although some people make a spontaneous recovery after mTBI, nearly half continue to experience persistent symptoms linked to their injury. Monitoring of recovery from mTBI may be needed and interventions provided for those experiencing persistent difficulties. Demographic factors and medical history should be taken into account in treatment planning.

DeLLITE Depression in late life: an intervention trial of exercise. Design and recruitment of a randomised controlled trial

BackgroundPhysical activity shows potential in combating the poor outcomes associated with depression in older people. Meta-analyses show gaps in the research with poor trial design compromising certainty in conclusions and few programmes showing sustained effects.Methods/designThe Depression in Late Life: an Intervention Trial of Exercise (DeLLITE) is a 12 month randomised controlled trial of a physical activity intervention to increase functional status in people aged 75 years and older with depressive symptoms. The intervention involves an individualised activity programme based on goal setting and progression of difficulty of activities delivered by a trained nurse during 8 home visits over 6 months. The control group received time matched home visits to discuss social contacts and networks. Baseline, 6 and 12 months measures were assessed in face to face visits with the primary outcome being functional status (SPPB, NEADL). Secondary outcomes include depressive symptoms (Geriatric Depression Scale), quality of life (SF-36), physical activity (AHS Physical Activity Questionnaire) and falls (self report).DiscussionDue to report in 2008 the DeLLITE study has recruited 70% of those eligible and tests the efficacy of a home based, goal setting physical activity programme in improving function, mood and quality of life in older people with depressive symptomatology. If successful in improving function and mood this trial could prove for the first time that there are long term health benefit of physical activity, independent of social activity, in this high risk group who consume excess health related costs.Trial registrationAustralian and New Zealand Clinical Trials Register ACTRN12605000475640

Nurse-patient communication in primary care diabetes management: an exploratory study

BackgroundDiabetes is a major health issue for individuals and for health services. There is a considerable literature on the management of diabetes and also on communication in primary care consultations. However, few studies combine these two topics and specifically in relation to nurse communication. This paper describes the nature of nurse-patient communication in diabetes management.MethodsThirty-five primary health care consultations involving 18 patients and 10 nurses were video-recorded as part of a larger multi-site study tracking health care interactions between health professionals and patients who were newly diagnosed with Type 2 diabetes. Patients and nurses were interviewed separately at the end of the 6-month study period and asked to describe their experience of managing diabetes. The analysis used ethnography and interaction analysis.In addition to analysis of the recorded consultations and interviews, the number of consultations for each patient and total time spent with nurses and other health professionals were quantified and compared.ResultsThis study showed that initial consultations with nurses often incorporated completion of extensive checklists, physical examination, referral to other health professionals and distribution of written material, and were typically longer than consultations with other health professionals. The consultations were driven more by the nurses’ clinical agenda than by what the patient already knew or wanted to know. Interactional analysis showed that protocols and checklists both help and hinder the communication process. This contradictory outcome was also evident at a health systems level: although organisational targets may have been met, the patient did not always feel that their priorities were attended to. Both nurses and patients reported a sense of being overwhelmed arising from the sheer volume of information exchanged along with a mismatch in expectations.ConclusionsConscientious nursing work was evident but at times misdirected in terms of optimal use of time. The misalignment of patient expectations and clinical protocols highlights a common dilemma in clinical practice and raises questions about the best ways to balance the needs of individuals with the needs of a health system. Video- recording can be a powerful tool for reflection and peer review.

'You just got to eat healthy': the topic of CAM in the general practice consultation

Abstract New Zealand research suggests that CAM use by GPs has decreased, while referral to CAM practitioners by GPs has increased, and that patients often do not tell their health practitioners when they are using CAM. The New Zealand Medical Council has developed guidelines for GPs who use CAM. However, there is no research in New Zealand that looks at how patients and GPs respond to CAM issues in the consultation. This paper uses data collected for two research projects on doctor – patient interaction. For this research, consultations between 105 patients and nine GPs were video-recorded. In this data set, all doctors but one were ‘orthodox’ and to some degree reserved judgement on CAM, albeit remaining cautious in how they made this evident. Patients on the other hand demonstrated a variety of strategies to get CAM on the agenda, and GPs were careful to couch any criticism in such a way as to protect the face’ of patients.
