Teenage use of GP care for moderate to severe asthma in Auckland, New Zealand.

OBJECTIVES: To describe and understand teenagers' frequency of attendance for General Practitioner (GP) care of moderate to severe asthma in the Auckland region. METHODS: Ten Auckland schools identified 510 children aged 13-14 years with breathing problems, who were invited to complete a screening questionnaire. 271 children participated, of whom 114 had moderate to severe asthma. RESULTS: 39% of the 114 had made 0-1 GP visit for asthma, and 17% made 'greater than and equal to' 5 visits. Low attendees (0-1 visit) were disproportionately New Zealand European. High attendees ('greater than and equal to' 5 visits) tended to be Maori and/or Pacific Islanders. Half of the teenagers attended GP asthma care as often as it wanted, independently of ethnicity; 62% tell their parents when they cannot manage their asthma; and 29% must pay for GP care. Expected attendance was increased for Maori and Pacific students versus others by 77% (p=0002), and by asthma of increased severity (p<0.001). Teenager resistance to accessing GP asthma care reduced expected attendance by 24% (p=0.003). CONCLUSIONS: Maori and Pacific peoples have traditionally faced barriers to accessing GP care, but their their more frequent attendance (than New Zealand Europeans) in this case, challenges whether such barriers persist, at least for acute care of moderate to severe asthma.

Attendance for general practitioner asthma care by children with moderate to severe asthma in Auckland, New Zealand.

Attendance for general practitioner (GP) care of childhood asthma varies widely in New Zealand (NZ). There is little current research to account for the variations, although groups such as Māori and Pacific peoples have traditionally faced barriers to accessing GP care. This paper aims to describe and account for attendance levels for GP asthma care among 6-9 year-olds with moderate to severe asthma in Auckland, NZ. During 2002, randomly selected schools identified all 6-9 year-olds with possible breathing problems. Completion of a questionnaire by each parent/guardian indicated which children had moderate to severe asthma, and what characteristics influenced their access to GP asthma care. A multilevel, negative binomial regression model (NBRM) was fitted to account for the number of reported GP visits for asthma, with adjustment for clustering within schools. Twenty-six schools (89.7 percent) identified 931 children with possible breathing problems. Useable questionnaires were returned to schools by 455 children (48.9 percent). Results indicated 209 children with moderate to severe asthma, almost one in every three reportedly making 5 or more GP visits for asthma in the previous year. Māori, Pacific and Asian children were disproportionately represented among these 'high attendees'. Low attendees (0-2 visits) were mainly NZ Europeans. The NBRM (n=155) showed that expected visits were increased by perceived need, ill-health, asthma severity and, in particular, Māori and Pacific child ethnicity. It may be that Māori and Pacific children no longer face significant barriers to accessing GP asthma care. However, more likely is that barriers apply only to accessing routine, preventative care, leading to poor asthma control, exacerbations requiring acute care, and paradoxically an increase in GP visits. That barriers may increase total numbers of visits challenges the assumption, for all health systems, that access can be defined in terms of barriers that must be overcome to obtain health care.

Integrating healthcare: the Counties Manukau experience.

In 1998, Counties Manukau District Health Board (CMDHB) was experiencing rapidly increasing demands on its secondary services. It was finding it increasingly difficult to meet the health needs of its relatively deprived population. There was widespread evidence of "systems failure", with poor coordination of primary and secondary services. A strategic plan was devised to meet identified priorities and this was subsequently implemented with extensive community involvement. A "disruptive change" model was utilised. Thirty separate projects were undertaken to improve coordination and integration of health services. Brief summaries of all projects are presented, and full evaluations were performed of major projects. Factors critical to project success were: dedicated and effective leadership; involvement of clinical staff; early engagement of the Maori and Pacific community; careful selection of stakeholders; reassurance for providers about privacy issues; close monitoring of project progress; realistic timeframes; and adequate initial funding. CMDHB believes that the critical factor to success in improving the performance of the health sector will be the ability of our key leaders in primary and secondary care, in both management and clinical roles, to adopt a systems view to problem analysis and solution building

Primary options for acute care: general practitioners using their skills to manage "avoidable admission" patients in the community.

AIM: To enroll 600 primary care "avoidable admission" patients in a programme that utilised general practitioners to manage those patients in the community. METHODS: The Primary Options for Acute Care (POAC) programme ran from 26 February to 31 December 2001. Using networks already established, primary care teams were invited to manage patients using any resources they required, up to a cost of approximately $266 per patient. If needed, a Service Coordinator was available to arrange investigations, care, or treatment. RESULTS: From 26 February to 31 December 2001, 707 patients were enrolled in POAC by 100 GPs. 104 patients (15%) were eventually admitted to hospital. An average of $200.73 per patient per episode was spent (not including administrative costs). A wide variety of patients and diseases were managed. Patients and general practitioners reported high levels of satisfaction with the programme. CONCLUSION: POAC demonstrated the ability and willingness of primary care providers to successfully manage patients who traditionally would be sent to hospital, within a defined budget

The development and implementation of the Chronic Care Management Programme in Counties Manukau.

AIMS: To develop an effective and efficient process for the seamless delivery of care for targeted patients with specific chronic diseases. To reduce inexplicable variation and maximise use of available resources by implementing evidence-based care processes. To develop a programme that is acceptable and applicable to the Counties Manukau region. METHODS: A model for the management of people with chronic diseases was developed. Model components and potential interventions were piloted. For each disease project, a return on investment was calculated and external evaluation was undertaken. The initial model was subsequently modified and individual disease projects aligned to it. RESULTS: The final Chronic Care Management model, agreed in September 2001, described a single common process. Key components were the targeting of high risk patients, organisation of cost effective interventions into a system of care, and an integrated care server acting as a data warehouse with a rules engine, providing flags and reminders. Return on investment analysis suggested potential savings for each disease component from $277 to $980 per person per annum. CONCLUSIONS: For selected chronic diseases, introduction of an integrated chronic care management programme, based on internationally accepted best practice processes and interventions can make significant savings, reducing morbidity and improving the efficiency of health delivery in the Counties Manukau region.

Establishing a Maori case management clinic.

AIMS: The Maori Case Management Clinic Project aims to improve Maori health outcomes by establishing low cost, high quality, culturally appropriate primary care facilities in targeted areas, with a focus on the management of chronic illness. Further, the project aims to evaluate this 'by Maori for Maori' model of community healthcare delivery. METHODS: Working in partnership with local Maori health providers, we analysed the available health utilisation and demographic data to choose the three best sites to establish new primary care facilities. We established the facilities with initial start-up funding from Counties Manukau District Health Board. Rigorous evaluation processes have been built into the project. RESULTS: Enrollments at the first of the three clinics exceeded expectations. Client satisfaction as reported by independent evaluators was very high, with cost, cultural acceptability and convenience of location being the three most common reasons given for high satisfaction. CONCLUSIONS: The model adopted has been positively received by the targeted population. Further evaluation will reveal whether this resulted in improved health outcomes.

General practitioners' assessments of the primary care caseload in Middlemore Hospital Emergency Department.

AIM: To estimate the proportion of Middlemore Hospital Emergency Department (ED) attendances that GPs thought could be handled in primary care. METHODS: A retrospective review of 300 randomly selected discharge summaries of non-admitted patients by 12 GPs. RESULTS: Data were available from 278 discharges. Agreement between GP reviewers was "fair" (kappa = 0.34, Kendall's W = 0.48). In 50 cases, the GPs were unanimous that the case was a primary care case (18%). In two cases, there was unanimity that the case was an ED case (<1%). The 12 GPs assessed that an average of 56% (range 38-81%) of the cases they reviewed could have been handled in their surgeries yesterday with no extra resources. This suggests that 34% of the total ED caseload (ie, including admitted patients) could be managed in primary care. CONCLUSIONS: A significant proportion of ED attendances at Middlemore Hospital could be handled in primary care; however, there is considerable variation in GP estimates of this proportion.

GP care for moderate to severe asthma in children: what do infrequently attending mothers disagree with and why?

OBJECTIVES: Our aim was to identify and account for areas of disagreement with GP care for moderate to severe child asthma among mothers who infrequently use this care. Identifying and understanding these areas of disagreement has the potential to improve child access to GP care. METHODS: This qualitative study in Auckland, New Zealand, used a general inductive approach to analyse 23 semi-structured, personal interviews during March-October 2001 with samples of 11 mothers of children with moderate to severe asthma, and 12 medical providers (10 in general practice and two in hospital emergency departments). Disagreement was defined by mothers' non-acceptance or disapproval of aspects of GP care they reported getting for child asthma. RESULTS: Mothers and providers described four areas in which some mothers disagree with aspects of GP care for child asthma. Contributing to infrequent attendance, the areas are the validity of the diagnosis, the level of service provision, the effectiveness of care and the level of respect from practice staff. These areas revealed three groups of mothers. GP factors contributing to disagreements among mothers were reported to be inconsistent care; information deficits on asthma and individual children; a lack of commitment to identifying the cause(s) and self-management of asthma in children; and an unmet need for asthma management plans that incorporate families' knowledge, goals and preferences. CONCLUSIONS: Disagreement, among mothers, with areas of GP care for child asthma contributes to non-attendance for this care. This paper identifies opportunities for GPs to keep disagreements to a minimum and facilitate access.

Quality of care indicators for population-based primary care in New Zealand.

AIM: To develop a set of non-invasive, evidence-based, population-based quality of care indicators for primary care in New Zealand and to test their feasibility. METHODS: New Zealand, British and Australian publications were reviewed and a set of quality of care indicators was constructed. These were trialed on data collected from seventeen fully computerised practices from the FirstHealth network of general practices. RESULTS: 28 indicators are proposed in five categories: smoking cessation, preventive health activities, prescribing quality, chronic disease management and data quality. We were able to calculate ten indicators from data already collected routinely, a further twelve could be calculated now with more sophisticated data queries and six would require the trial practices to collect further data. CONCLUSIONS: While any set of indicators is arbitrary there are sufficient research data to support a set of evidence-based, population-focused, quality of care indicators in New Zealand primary health care. In computerised practices these indicators can be calculated from routinely collected data.

Reasons for poor understanding of when and how to access GP care for childhood asthma in Auckland, New Zealand.

BACKGROUND: Attempts to explain why some patients lack the understanding needed to access GP care for childhood asthma are uncommon and have tended to be based on reported statistical associations. OBJECTIVES: The aims of this study were to describe and account for poor patient understanding of when and how to access GP care for childhood asthma in Auckland, New Zealand. METHODS: A general inductive approach was used to analyse 29 semi-structured, personal interviews, during March-May 2001, with Auckland key informants selected through maximum variation sampling. Informant checking and the literature supported the text analysis by two independent researchers. RESULTS: Key informants reported wide variations in the extent to which guardians and asthmatic children understand when and how to access GP services. Two sets of barriers to patient understanding were identified. The first limits the willingness of people to seek understanding and the second limits their ability to understand, even if they want to understand. CONCLUSIONS: Use of qualitative methodology was able to reveal barriers to patient understanding. Strategies operating at the GP and system levels were identified to help overcome these barriers.

How much variation in clinical activity is there between general practitioners? A multi-level analysis of decision-making in primary care.

OBJECTIVES: There is considerable policy interest in medical practice variation (MPV). Although the extent of MPV has been quantified for secondary care, this has not been investigated adequately in general practice. Technical obstacles to such analyses have been presented by the reliance on ecological small area variation (SAV) data, the binary nature of many clinical outcomes in primary care and by diagnostic variability. The study seeks to quantify the extent of variation in clinical activity between general practitioners by addressing these problems. METHODS: A survey of nearly 10 000 encounters drawn from a representative sample of general practitioners in the Waikato region of New Zealand was carried out in the period 1991-1992. Participating doctors recorded all details of clinical activity for a sample of encounters. Measures used in this analysis are the issuing of a prescription, the ordering of a laboratory test or radiology examination, and the recommendation of a future follow-up office visit at a specified date. An innovative statistical technique is adopted to assess the allocation of variance for binary outcomes within a multi-level analysis of decision-making. RESULTS: As expected, there was considerable variability between doctors in levels of prescribing, ordering of investigations and requests for follow up. These differences persisted after controlling for case-mix and patient and practitioner attributes. However, analysis of the components of variance suggested that less than 10% of remaining variability occurred at the practitioner level for any of the measures of clinical activity. Further analysis of a single diagnostic group--upper respiratory tract infection--marginally increased the practitioner contribution. CONCLUSIONS: The amount of variability in clinical activity that can definitively be linked to the practitioner in primary care is similar to that recorded in studies of the secondary sector. With primary care doctors increasingly being grouped into larger professional organisations, we can expect application of multi-level techniques to the analysis of clinical activity in primary care at different levels of organisational complexity.
