'Water dripping on a stone': a feasibility study of a healthy weight management conversation approach in routine general practice consultations.

BACKGROUND: Primary health care has an important role to play in the management of weight and yet discussions of healthy weight management do not occur optimally, indicating a need for simple tools and training in brief weight counselling. The 'FABS' approach (focusing on four topic areas: Food, Activity, Behaviour and Support) was developed to address this. OBJECTIVES: To explore the feasibility of the 'FABS' approach within routine general practice consultations and its effectiveness in facilitating healthy weight conversations. METHOD: The FABS approach was run for a trial period in five New Zealand general practices. The approach entailed staff training, the addition to the practice patient management system of a template outlining potential topics for discussion and a patient handout. GPs were asked to use the approach with any adult patient with a body mass index of over 28 kg/m2. A descriptive analysis of anonymized quantitative practice data was conducted, with limited qualitative data from an online clinician questionnaire and interviews with GPs and patients. RESULTS: Over 4 months, the template was opened 862 times by 27 clinicians in 830 patient consultations. All FABS topics were raised at least once. Physical activity was raised most frequently, followed by two food-related topics. There was variation between practices and between GPs. GPs tended to raise more topics within a single consultation than the training recommended. The limited clinician survey results and patient interviews also indicated positive responses to the approach. CONCLUSIONS: It is possible to provide an infrastructure for healthy weight conversation approaches within general practice so that patients receive supportive and consistent messages on a regular basis. General practice is an appropriate setting for this due to the ongoing relationships with patients and team-based approach, but there is a need for effective training and education to ensure appropriate and effectively delivery.

Impact of a comprehensive digital health programme on HbA1c and weight after 12 months for people with diabetes and prediabetes: a randomised controlled trial.

AIMS/HYPOTHESIS: The aim of this RCT was to evaluate the effectiveness of a digital health programme (BetaMe/Melon) vs usual care in improving the control of type 2 diabetes and prediabetes in a primary care population. METHODS: We conducted a randomised parallel-group two-arm single-blinded superiority trial in the primary care setting in two regions of New Zealand. Eligible participants were identified through Primary Health Organisations and participating practices. Eligibility criteria were as follows: age 18-75 years, HbA1c 41-70 mmol/mol (5.9-8.6%), not taking insulin, and daily access to the internet. BetaMe/Melon is a 12 month mobile-device and web-based programme with four components: health coaching; evidence-based resources; peer support; and goal tracking. Participants were randomised into the intervention or control arm (1:1 allocation) based upon baseline HbA1c (prediabetes or diabetes range), stratified by practice and ethnicity. Research nurses and the study biostatistician were blind to study arm. Primary outcomes of the study were changes in HbA1c and weight at 12 months, using an intention-to-treat analysis. RESULTS: Four hundred and twenty-nine individuals were recruited between 20 June 2017 and 11 May 2018 (n = 215 intervention arm, n = 214 control arm), most of whom were included in analyses of co-primary outcomes (n = 210/215, 97.7% and n = 213/214, 99.5%). HbA1c levels at 12 months did not differ between study arms: mean difference was -0.9 mmol/mol (95% CI -2.9, 1.1) (-0.1% [95% CI -0.3, 0.1]) for the diabetes group and was 0.0 mmol/mol (95% CI -0.9, 0.9) (0.0% [95% CI -0.1, 0.1]) for the prediabetes group. Weight reduced slightly at 12 months for participants in both study arms, with no difference between arms (mean difference -0.4 kg [95% CI -1.3, 0.5]). CONCLUSIONS/INTERPRETATION: This study did not demonstrate clinical effectiveness for this particular programme. Given their high costs, technology-assisted self-management programmes need to be individually assessed for their effectiveness in improving clinical outcomes for people with diabetes.

Communication in high risk ante-natal consultations: a direct observational study of interactions between patients and obstetricians.

BACKGROUND: Effective communication is crucial to any doctor-patient consultation, not least in pregnancy where the outcome affects more than one person. While higher levels of patient participation and shared decision making are recognised as desirable, there is little agreement on how best to achieve this. Most previous research in this area is based on reported data such as interviews or surveys and there is a need for more fine-grained analysis of authentic interaction. This study aimed to identify the discourse characteristics and patterns that exemplify effective communication practices in a high-risk ante-natal clinic. METHODS: We video-recorded 20 consultations in a high-risk ante-natal clinic in a large New Zealand city with patients attending for the first time. Post-consultation interviews were conducted with the 20 patients and 13 obstetricians involved. Discourse analysis of the transcripts and videos of the consultations was conducted, in conjunction with thematic analysis of interview transcripts. RESULTS: Most patients reported high quality communication and high levels of satisfaction; the detailed consultation analysis revealed a range of features likely to have contributed. On the clinician side, these included clear explanations, acknowledgement of the patient's experience, consideration of patient wishes, and realistic and honest answers to patient questions. On the patient side, these included a high level of engagement with technical aspects of events and procedures, and appropriate questioning of obstetricians. CONCLUSIONS: This study has demonstrated the utility of combining direct observation of consultations with data from patient experience interviews to identify specific features of effective communication in routine obstetric ante-natal care. The findings are relevant to improvements needed in obstetric communication identified in the literature, especially in relation to handling psychosocial issues and conveying empathy, and may be useful to inform communication training for obstetricians. The presence of the unborn child may provide an added incentive for parents to develop their own health literacy and to be an active participant in the consultation on behalf of their child. The findings of this study can lay the groundwork for further, more detailed analysis of communication in ante-natal consultations.

Uncovering social structures and informational prejudices to reduce inequity in delivery and uptake of new molecular technologies.

Advances in molecular technologies have the potential to help remedy health inequities through earlier detection and prevention; if, however, their delivery and uptake (and therefore any benefits associated with such testing) are not more carefully considered, there is a very real risk that existing inequities in access and use will be further exacerbated. We argue this risk relates to the way that information and knowledge about the technology is both acquired and shared, or not, between health practitioners and their patients.A healthcare system can be viewed as a complex social network comprising individuals with different worldviews, hierarchies, professional cultures and subcultures and personal beliefs, both for those giving and receiving care. When healthcare practitioners are not perceived as knowledge equals, they would experience informational prejudices, and the result is that knowledge dissemination across and between them would be impeded. The uptake and delivery of a new technology may be inequitable as a result. Patients would also experience informational prejudice when they are viewed as not being able to understand the information that is presented to them, and information may be withheld.Informational prejudices driven by social relations and structures have thus far been underexplored in considering (in)equitable implementation and uptake of new molecular technologies. Every healthcare interaction represents an opportunity for experiencing informational prejudice, and with it the risk of being inappropriately informed for undertaking (or offering) such screening or testing. Making knowledge acquisition and information dissemination, and experiences of informational prejudice, explicit through sociologically framed investigations would extend our understandings of (in)equity, and offer ways to affect network relationships and structures that support equity in delivery and uptake.

A Mobile- and Web-Based Health Intervention Program for Diabetes and Prediabetes Self-Management (BetaMe/Melon): Process Evaluation Following a Randomized Controlled Trial.

BACKGROUND: Technology-assisted self-management programs are increasingly recommended to patients with long-term conditions such as diabetes. However, there are a number of personal and external factors that affect patients' abilities to engage with and effectively utilize such programs. A randomized controlled trial of a multi-modal online program for diabetes self-management (BetaMe/Melon) was conducted in a primary care setting, and a process evaluation was completed at the end of the study period. OBJECTIVE: This process evaluation aimed to examine the utilization patterns of BetaMe/Melon, identify which components participants found most (and least) useful, and identify areas of future improvement. METHODS: Process evaluation data were collected for intervention arm participants from 3 sources: (1) the mobile/web platform (to identify key usage patterns over the 16-week core program), (2) an online questionnaire completed during the final study assessment, and (3) interviews conducted with a subset of participants following the study period. Participants were classified as "actively engaged" if any usage data was recorded for the participant (in any week), and patterns were reported by age, gender, ethnicity, and diabetes/prediabetes status. The online questionnaire asked participants about the usefulness of the program and whether they would recommend BetaMe/Melon to others according to a 5-point Likert Scale. Of 23 invited participants, 18 participated in a digitally recorded, semistructured telephone interview. Interview data were thematically analyzed. RESULTS: Out of the 215 participants, 198 (92%) received an initial health coaching session, and 160 (74%) were actively engaged with the program at some point during the 16-week core program. Engagement varied by demographic, with women, younger participants, and ethnic majority populations having higher rates of engagement. Usage steadily declined from 50% at Week 0 to 23% at Week 15. Participants ranked component usefulness as education resources (63.7%), health coaches (59.2%), goal tracking (48.8%), and online peer support (42.1%). Although 53% agreed that the program was easy to use, 64% would recommend the program to others. Interview participants found BetaMe/Melon useful overall, with most identifying beneficial outcomes such as increased knowledge, behavioral changes, and weight loss. Barriers to engagement were program functionality, internet connectivity, incomplete delivery of all program components, and participant motivation. Participants suggested a range of improvements to the BetaMe/Melon program. CONCLUSIONS: The program was generally well received by participants; active engagement was initially high, although it declined steadily. Maintaining participant engagement over time, individualizing programs, and addressing technical barriers are important to maximize potential health benefits from online diabetes self-management programs.

The Fear Reduction Exercised Early (FREE) approach to management of low back pain in general practice: A pragmatic cluster-randomised controlled trial.

BACKGROUND: Effective and cost-effective primary care treatments for low back pain (LBP) are required to reduce the burden of the world's most disabling condition. This study aimed to compare the clinical effectiveness and cost-effectiveness of the Fear Reduction Exercised Early (FREE) approach to LBP (intervention) with usual general practitioner (GP) care (control). METHODS AND FINDINGS: This pragmatic, cluster-randomised controlled trial with process evaluation and parallel economic evaluation was conducted in the Hutt Valley, New Zealand. Eight general practices were randomly assigned (stratified by practice size) with a 1:1 ratio to intervention (4 practices; 34 GPs) or control group (4 practices; 29 GPs). Adults presenting to these GPs with LBP as their primary complaint were recruited. GPs in the intervention practices were trained in the FREE approach, and patients presenting to these practices received care based on the FREE approach. The FREE approach restructures LBP consultations to prioritise early identification and management of barriers to recovery. GPs in control practices did not receive specific training for this study, and patients presenting to these practices received usual care. Between 23 September 2016 and 31 July 2017, 140 eligible patients presented to intervention practices (126 enrolled) and 110 eligible patients presented to control practices (100 enrolled). Patient mean age was 46.1 years (SD 14.4), and 46% were female. The duration of LBP was less than 6 weeks in 88% of patients. Primary outcome was change from baseline in patient participant Roland Morris Disability Questionnaire (RMDQ) score at 6 months. Secondary patient outcomes included pain, satisfaction, and psychosocial indices. GP outcomes included attitudes, knowledge, confidence, and GP LBP management behaviour. There was active and passive surveillance of potential harms. Patients and outcome assessors were blind to group assignment. Analysis followed intention-to-treat principles. A total of 122 (97%) patients from 32 GPs in the intervention group and 99 (99%) patients from 25 GPs in the control group were included in the primary outcome analysis. At 6 months, the groups did not significantly differ on the primary outcome (adjusted mean RMDQ score difference 0.57, 95% CI -0.64 to 1.78; p = 0.354) or secondary patient outcomes. The RMDQ difference met the predefined criterion to indicate noninferiority. One control group participant experienced an activity-related gluteal tear, with no other adverse events recorded. Intervention group GPs had improvements in attitudes, knowledge, and confidence compared with control group GPs. Intervention group GP LBP management behaviour became more guideline concordant than the control group. In cost-effectiveness, the intervention dominated control with lower costs and higher Quality-Adjusted Life Year (QALY) gains. Limitations of this study were that although adequately powered for primary outcome assessment, the study was not powered for evaluating some employment, healthcare use, and economic outcomes. It was also not possible for research nurses (responsible for patient recruitment) to be masked on group allocation for practices. CONCLUSIONS: Findings from this study suggest that the FREE approach improves GP concordance with LBP guideline recommendations but does not improve patient recovery outcomes compared with usual care. The FREE approach may reduce unnecessary healthcare use and produce economic benefits. Work participation or health resource use should be considered for primary outcome assessment in future trials of undifferentiated LBP. TRIAL REGISTRATION: ACTRN12616000888460.

Damp mouldy housing and early childhood hospital admissions for acute respiratory infection: a case control study.

INTRODUCTION: A gap exists in the literature regarding dose-response associations of objectively assessed housing quality measures, particularly dampness and mould, with hospitalisation for acute respiratory infection (ARI) among children. METHODS: A prospective, unmatched case-control study was conducted in two paediatric wards and five general practice clinics in Wellington, New Zealand, over winter/spring 2011-2013. Children aged <2 years who were hospitalised for ARI (cases), and either seen in general practice with ARI not requiring admission or for routine immunisation (controls) were included in the study. Objective housing quality was assessed by independent building assessors, with the assessors blinded to outcome status, using the Respiratory Hazard Index (RHI), a 13-item scale of household quality factors, including an 8-item damp-mould subscale. The main outcome was case-control status. Adjusted ORs (aORs) of the association of housing quality measures with case-control status were estimated, along with the population attributable risk of eliminating dampness-mould on hospitalisation for ARI among New Zealand children. RESULTS: 188 cases and 454 controls were studied. Higher levels of RHI were associated with elevated odds of hospitalisation (OR 1.11/unit increase (95% CI 1.01 to 1.21)), which weakened after adjustment for season, housing tenure, socioeconomic status and crowding (aOR 1.04/unit increase (95% CI 0.94 to 1.15)). The damp-mould index had a significant, adjusted dose-response relationship with ARI admission (aOR 1.15/unit increase (95% CI 1.02 to 1.30)). By addressing these harmful housing exposures, the rate of admission for ARI would be reduced by 19% or 1700 fewer admissions annually. CONCLUSIONS: A dose-response relationship exists between housing quality measures, particularly dampness-mould, and young children's ARI hospitalisation rates. Initiatives to improve housing quality and to reduce dampness-mould would have a large impact on ARI hospitalisation.

Attempting rigour and replicability in thematic analysis of qualitative research data; a case study of codebook development.

BACKGROUND: Navigating the world of qualitative thematic analysis can be challenging. This is compounded by the fact that detailed descriptions of methods are often omitted from qualitative discussions. While qualitative research methodologies are now mature, there often remains a lack of fine detail in their description both at submitted peer reviewed article level and in textbooks. As one of research's aims is to determine the relationship between knowledge and practice through the demonstration of rigour, more detailed descriptions of methods could prove useful. Rigour in quantitative research is often determined through detailed explanation allowing replication, but the ability to replicate is often not considered appropriate in qualitative research. However, a well described qualitative methodology could demonstrate and ensure the same effect. METHODS: This article details the codebook development which contributed to thematic analysis of qualitative data. This analysis formed part of a mixed methods multiphase design research project, with both qualitative and quantitative inquiry and involving the convergence of data and analyses. This design consisted of three distinct phases: quantitative, qualitative and implementation phases. RESULTS AND CONCLUSIONS: This article is aimed at researchers and doctoral students new to thematic analysis by describing a framework to assist their processes. The detailed description of the methods used supports attempts to utilise the thematic analysis process and to determine rigour to support the establishment of credibility. This process will assist practitioners to be confident that the knowledge and claims contained within research are transferable to their practice. The approach described within this article builds on, and enhances, current accepted models.

A Longitudinal Study of Interactions Between Health Professionals and People With Newly Diagnosed Diabetes.

PURPOSE: We undertook a study to observe in detail the primary care interactions and communications of patients with newly diagnosed diabetes over time. In addition, we sought to identify key points in the process where miscommunication might occur. METHODS: All health interactions of 32 patients with newly diagnosed type 2 diabetes were recorded and tracked as they moved through the New Zealand health care system for a period of approximately 6 months. Data included video recordings of patient interactions with the health professionals involved in their care (eg, general practitioners, nurses, dietitians). We analyzed data with ethnography and interaction analysis. RESULTS: Challenges to effective communication in diabetes care were identified. Although clinicians showed high levels of technical knowledge and general communication skill, initial consultations were often driven by biomedical explanations out of context from patient experience. There was a perception of time pressure, but considerable time was spent with patients by health professionals repeating information that may not be relevant to patient need. Health professionals had little knowledge of what disciplines other than their own do and how their contributions to patient care may differ. CONCLUSIONS: Despite current high skill levels of primary care professionals, opportunities exist to increase the effectiveness of communication and consultation in diabetes care. The various health professionals involved in patient care should agree on the length and focus of each consultation.

Primary care physicians' use of the proposed classification of common mental disorders for ICD-11.

Background: The World Health Organization is revising the classification of common mental disorders in primary care for ICD-11. Major changes from the ICD-10 primary care version have been proposed for: (i) mood and anxiety disorders; and (ii) presentations of multiple somatic symptoms (bodily stress syndrome). This three-part field study explored the implementation of the revised classification by primary care physicians (PCPs) in five countries. Methods: Participating PCPs in Brazil, China, Mexico, Pakistan and Spain were asked to use the revised classification, first in patients that they suspected might be psychologically distressed (Part 1), and second in patients with multiple somatic symptoms causing distress or disability not wholly attributable to a known physical pathology, or with high levels of health anxiety (Part 2). Patients referred to Part 1 or Part 2 underwent a structured diagnostic interview. Part 3 consisted of feedback from PCPs regarding the classification. Results: In Part 1, anxious depression was the most common disorder among referred patients. PCPs assigned the highest severity ratings to anxious depression, and the next highest to current depression; current anxiety was rated as least severe. Considerable overlap was found between bodily stress syndrome (BSS) and health anxiety (HA). The psychiatric interview recorded higher rates of mood and anxiety disorders diagnoses among patients with BSS than did PCPs. PCPs' satisfaction with the revised classification was high. Conclusions: Results generally supported the inclusion of the new categories of anxious depression, BSS and HA for ICD-11 PHC and suggested that PCPs could implement these categories satisfactorily.

"I can't bend it and it hurts like mad": direct observation of gout consultations in routine primary health care.

BACKGROUND: Gout is the most common form of inflammatory arthritis and is associated with considerable co-morbidity. It is usually managed in the primary care setting with a combination of lifestyle modification and pharmacological therapy. This study describes patterns of communication about gout observed in interactions between patients and primary care practitioners during routine consultations. METHODS: Secondary analysis of video-recordings of individual healthcare consultations between patients and a range of primary care practitioners (including general practitioners, practice nurses, podiatrists and dietitians) from an archived database. Consultations that included any discussion about gout were eligible for inclusion (n = 31) and were not restricted to those where gout was the main presenting complaint. The consultation transcripts were analysed using a qualitative inductive approach from clinical and linguistic perspectives and supplemented with visual observation of the interactions. RESULTS: Two main themes emerged from the data; the importance of gout and 'telling' versus 'listening' in consultations. The first theme had two distinct strands; gout as an incidental part of the consultation and the impact of gout on patients. A trend towards more didactic practitioner communication encompassed by the second theme occurred at many different consultation points including diagnosis, in more general post-diagnosis discussion, and when discussing biochemical test results and lifestyle advice. In contrast, when discussion about treatment with medicines occurred a tendency towards a greater degree of listening to patients was observed. CONCLUSION: Our observation of the communication patterns in these consultations illustrates an inherent complexity of gout consultations in primary care. Gout may be more important to patients than is often apparent to practitioners in routine consultations. Consultation management needs to take into account the impact of the condition and the balance of information provided around lifestyle advice versus long-term management with medicines.

'It depends on the consultation': revisiting use of family members as interpreters for general practice consultations - when and why?

Family members continue to be used as interpreters in medical consultations despite the well-known risks. This paper examines participant perceptions of this practice in three New Zealand clinics chosen for their frequent use of interpreters and their skill in using them. It is based on a detailed study of 17 video-recorded interpreted consultations and 48 post-consultation interviews with participants (5 doctors, 16 patients and 12 interpreters, including 6 family members). All participants expressed satisfaction with the communication. Analysis of the interviews explored what participants liked or valued about family member interpreters (FMIs). Key themes were the FMIs' personal relationship and knowledge, patient comfort, trust, cultural norms, time efficiency and continued help outside the consultation. General practitioners (GPs) expressed awareness of potential risks and how to manage them, in contrast to patients and FMIs. Although the use of professional interpreters needs to be strongly promoted, a well-informed decision to use a family member is appropriate in some situations. GPs need to be well trained in how to assess and manage the risks. Rather than striving for 'best practice' (i.e. universal use of professional interpreters), it is better to aim for 'good practice' where a considered judgement is made about each situation on an individual basis.

Putting Physical Activity While Experiencing Low Back Pain in Context: Balancing the Risks and Benefits.

OBJECTIVE: To analyze attitudes and beliefs about movement and physical activity in people with low back pain (LBP) and compare these beliefs between people with acute and chronic LBP. DESIGN: Qualitative inductive analysis of data collected via face-to-face semistructured interviews. Interviews were audio-recorded and transcribed verbatim. SETTING: Participants were purposively recruited from 1 region of New Zealand. PARTICIPANTS: Persons with LBP (N=23), consisting of individuals with acute LBP (<6wk; n=12) and chronic LBP (>3mo; n=11). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Themes that emerged from participant interview transcripts using analysis based on Interpretative Description. RESULTS: Participants with acute and chronic LBP made judgments about physical activity and rest using the same conceptual model. Concerns about creating more pain, tissue damage, or impairment influenced the physical activity judgments of most participants with acute and chronic LBP. These perceived risks were balanced against the perceived benefits, the most important of which were psychological or social rather than physical. Judgments made by those with acute and chronic LBP were context dependent and influenced by the nature and duration of pain, the type of physical activity, the importance of the activity, and the participant's previous experience. Participants with acute pain who had not experienced back pain previously often expressed more uncertainty, whereas those with chronic LBP appeared to have developed cognitive rules that determined physical activity decisions. CONCLUSIONS: Exploring the perceived risks, benefits, and contextual factors that influence decisions about physical activity and rest may help clinicians to understand the behavior of patients with acute and chronic LBP. Clinicians may best support their patients to engage in physical activity by providing an informed assessment of risks and an explanation about the range of potential benefits.

"It's complicated" - talking about gout medicines in primary care consultations: a qualitative study.

BACKGROUND: Gout is the most common form of inflammatory arthritis. It is associated with substantial co-morbidity and often managed in primary care. A greater understanding of the communication process between patients and healthcare professionals provides one way of improving the management of this condition. This paper describes communication about gout medicines and treatment between patients and primary care health professionals during routine consultations. METHODS: Video-recordings of 31 individual healthcare consultations between patients and a range of primary care practitioners (general practitioners, practice nurses, podiatrists, dietitians) from an archived database were reviewed. Consultations that encompassed any discussion about gout medicines and treatment were included (n = 27) and were not solely restricted to those where gout was the presenting complaint. Themes were derived from an inductive qualitative analysis, from clinical and linguistic perspectives, based on the conversation between patients and practitioners about medicines and visual observation of these interactions. RESULTS: A number of factors were identified that had the potential to impact on the optimal management of gout in primary care. These included level of patient knowledge, patient attitudes to medicines, and the attributes of practitioner communication with patients. The latter related to the style of delivery and content of the information provided, and the ability of practitioners to make use of opportunities that arose to discuss these issues. CONCLUSIONS: Patients with gout communicate at varying levels of complexity with a diverse range of primary care healthcare professionals about the treatment of their condition. It is important that all practitioners engaging with gout patients in this setting are knowledgeable about the current management of gout, provide clear, consistent and accurate messages, remain aware that these messages may need repeating over time, and are supportive of patients' medicine-taking preferences.

Patient resistance as a resource: candidate obstacles in diabetes consultations.

This study uses conversation analysis to explore 'candidate obstacles', a practice observed in sequences of patient resistance to lifestyle advice within health professional consultations. This article presents illustrative analyses of selected data excerpts drawn from audio-visual recordings of 116 tracked consultations between health professionals and 34 patients newly diagnosed with type 2 diabetes mellitus in New Zealand. The analysis shows that in consultations where health promotion activities are central, patient resistance can provide space for patients to identify obstacles to their compliance with lifestyle advice. Identifying candidate obstacles provides opportunities for health professionals to align advice with concerns of patients and potentially improve patient outcomes.

Burden of Traumatic Brain Injury in New Zealand: Incidence, Prevalence and Disability-Adjusted Life Years.

OBJECTIVE: The study aimed to estimate the incidence, prevalence and disability-adjusted life years (DALY) for traumatic brain injury (TBI) in New Zealand (NZ) in 2010. METHODS: A multi-state life table model was constructed using inputs from the Brain Injury Outcomes New Zealand in the Community study for the first-ever incidence of TBI in a lifetime and its severity distribution, from the NZ Ministry of Health's Mortality Collection for the data on TBI mortality and from Statistics of NZ for the population data. The modeled estimate of prevalence was combined with the disability weights for TBI (by stage and severity level) from the Global Burden of Disease 2010 study to obtain estimates of health loss (DALYs) for TBI. RESULTS: Approximately, 11,300 first-ever incident TBIs occurred in NZ during 2010, with 527,000 New Zealanders estimated to have ever experienced a TBI (prevalent cases). The estimated 20,300 DALYs attributable to TBI accounted for 27% of total injury-related health loss and 2.4% of DALYs from all causes. Of the total DALYs attributable to TBI, 71% resulted from fatal injuries. However, non-fatal outcomes accounted for a substantial share of the burden (29%) with mild TBI making the greater contribution of non-fatal outcomes (56%). CONCLUSIONS: The burden of TBI in NZ is substantial, and mild TBI contributes to a major part of non-fatal outcomes.

Neuropsychological outcome and its correlates in the first year after adult mild traumatic brain injury: A population-based New Zealand study.

OBJECTIVE: The relationship between moderate/severe traumatic brain injury (TBI) and cognitive deficits is well known. The nature, duration and predictors of cognitive difficulties post-mild TBI remain unclear. This study examined cognitive, mood and post-concussion outcomes of mild TBI over 1-year post-injury. METHOD: Adults (>15 years) with mild TBI (n = 260) completed neuropsychological (CNS-Vital Signs, Behavioural Dyscontrol Scale), mood (Hospital Anxiety Depression Scale) and behavioural assessments (Cognitive Failures Questionnaire, Rivermead Post-Concussion Questionnaire) at baseline, 1-, 6- and 12-months post-injury. RESULTS: Over the 12-months post-injury self-reported cognition (p = 0.027), post-concussion symptoms (p < 0.001), depression (p < 0.001), anxiety (p < 0.001) and dyscontrol (p = 0.025) improved significantly. Assessments of memory, processing speed, executive function, psychomotor speed/reaction time, complex attention and flexibility also improved significantly. At baseline >20% of individuals produced very low scores on executive ability, complex attention and cognitive flexibility. At 1- and 6-month follow-ups >20% of participants were very low for complex attention, with 16.3% remaining so at 12-months. Executive abilities and speed were related to post-concussion symptoms, mood and self-reported cognition at 12-months. CONCLUSIONS: Whilst significant improvements were noted across measures over time, a significant proportion of individuals still perform poorly on neuropsychological measures 12-months after mild TBI; and these were linked to post-concussion symptoms, mood and self-reported cognitive outcomes. This implies a longer trajectory for recovery than has previously been suggested, which has implications for provision of assessment and rehabilitation services for more extended periods.

Identifying influenza-like illness presentation from unstructured general practice clinical narrative using a text classifier rule-based expert system versus a clinical expert.

BACKGROUND: We designed and validated a rule-based expert system to identify influenza like illness (ILI) from routinely recorded general practice clinical narrative to aid a larger retrospective research study into the impact of the 2009 influenza pandemic in New Zealand. METHODS: Rules were assessed using pattern matching heuristics on routine clinical narrative. The system was trained using data from 623 clinical encounters and validated using a clinical expert as a gold standard against a mutually exclusive set of 901 records. RESULTS: We calculated a 98.2 % specificity and 90.2 % sensitivity across an ILI incidence of 12.4 % measured against clinical expert classification. Peak problem list identification of ILI by clinical coding in any month was 9.2 % of all detected ILI presentations. Our system addressed an unusual problem domain for clinical narrative classification; using notational, unstructured, clinician entered information in a community care setting. It performed well compared with other approaches and domains. It has potential applications in real-time surveillance of disease, and in assisted problem list coding for clinicians. CONCLUSIONS: Our system identified ILI presentation with sufficient accuracy for use at a population level in the wider research study. The peak coding of 9.2 % illustrated the need for automated coding of unstructured narrative in our study.

Acute low back pain management in general practice: uncertainty and conflicting certainties.

BACKGROUND: Low back pain (LBP) is a significant health problem and common reason to visit the GP. Evidence suggests GPs experience difficulty applying evidence-based guidelines. OBJECTIVE: Explore GPs' underlying beliefs about acute LBP and how these influence their clinical management of patients. METHODS: Eleven GPs from one geographical region within New Zealand were recruited by purposive sampling. Audio recordings of semi-structured qualitative interviews were transcribed verbatim. Data were analysed with an Interpretive Description framework. RESULTS: Four key themes emerged related to the causes of acute LBP, GP confidence, communicating diagnostic uncertainty and encouraging movement and activity. Acute LBP was seen as a direct representation of tissue injury, consequently the assessment and management of patients' attitudes and beliefs was not a priority. Participants' confidence was decreased due to a perceived inability to diagnose or influence the tissue injury. Despite this, diagnoses were provided to patients to provide reassurance and meet expectations. Guideline recommendations regarding activity conflicted with a perceived need to protect damaged tissue, resulting in reported provision of mixed messages about the need to be both active and careful. CONCLUSIONS: GPs' initial focus upon tissue injury during acute care, and providing a diagnostic label, may influence patients' subsequent alignment with a biomedical perspective and contribute to consultation conflict and patients' perception of blame when discussion of psychosocial influences is introduced. Demonstrating the relevance of the biopsychosocial model to acute LBP may improve GPs' alignment with guidelines, improve their confidence to manage these patients and ultimately improve outcomes.

Framing the consultation: the role of the referral in surgeon-patient consultations.

This study describes and analyzes the impact of the referral process on communication at the beginning of surgeon-patient consultations. We used conversation analysis to analyze the opening interactional activities of surgeon-patient consultations in New Zealand. This study focuses on 20 video-recorded consultations recorded between 2004 and 2006. Participants in surgeon-patient consultations began referred consultations by discussing the referral letter in what we have termed "referral recognition sequences." These sequences are coconstructed activities that can be implicit or explicit and address the minimized epistemic distance between surgeons and patients that is caused by the referral process. These sequences can be simple or complex, and this complexity may be determined by the quality of the referral letter received. Acknowledgment of the referral letter assists in achieving alignment between surgeon, patient, and referring doctor regarding the presenting problem. If this alignment is not achieved, progressivity of the consultation is affected, as there is disagreement as to why the patient is seeing the surgeon. This research shows that to assist in the progressivity of surgeon-patient consultations, referral letters should be clear and patients made aware of the reason for referral. Surgeons should also overtly address the minimized epistemic distance caused by the referral letter to ensure patients present their problems in full.
