Rural New Zealand health professionals' perceived barriers to greater use of the internet for learning.

INTRODUCTION: The purpose of this research was to investigate rural North Island (New Zealand) health professionals' attitudes and perceived barriers to using the internet for ongoing professional learning. METHODS: A cross-sectional postal survey of all rural North Island GPs, practice nurses and pharmacists was conducted in mid-2003. The questionnaire contained both quantitative and qualitative questions. The transcripts from two open questions requiring written answers were analysed for emergent themes, which are reported here. The first open question asked: 'Do you have any comments on the questionnaire, learning, computers or the Internet?' The second open question asked those who had taken a distance-learning course using the internet to list positive and negative aspects of their course, and suggest improvements. RESULTS: Out of 735 rural North Island health professionals surveyed, 430 returned useable questionnaires (a response rate of 59%). Of these, 137 answered the question asking for comments on learning, computers and the internet. Twenty-eight individuals who had completed a distance-learning course using the internet, provided written responses to the second question. Multiple barriers to greater use of the internet were identified. They included lack of access to computers, poor availability of broadband (fast) internet access, lack of IT skills/knowledge, lack of time, concerns about IT costs and database security, difficulty finding quality information, lack of time, energy or motivation to learn new skills, competing priorities (eg family), and a preference for learning modalities which include more social interaction. Individuals also stated that rural health professionals needed to engage the technology, because it provided rapid, flexible access from home or work to a significant health information resource, and would save money and travelling time to urban-based education. CONCLUSIONS: In mid-2003, there were multiple barriers to rural North Island health professionals making greater use of the internet for learning. Now that access to broadband internet is available in all rural towns in New Zealand, there is a clear need to address the other identified barriers, especially the self-reported lack of IT skills, which are preventing many in the rural health workforce from gaining maximum advantage from both computers and the internet.

Lipids and CVD management: towards a global consensus.

Cardiovascular disease (CVD) is currently the leading cause of morbidity and mortality worldwide and its incidence is likely to increase. Multiple risk factors contribute to CVD. Elevated LDL-cholesterol (LDL-C) and triglyceride levels, low HDL-cholesterol levels, hypertension, type 2 diabetes, and smoking are key modifiable risk factors. Such risk factors are present in 80-90% of coronary heart disease (CHD) patients. For many factors, modification can significantly reduce CVD incidence. For example, statin-induced LDL-C reductions reduce cardiovascular events by 24-37% and smoking cessation reduces CHD mortality by 36%. The need to identify and treat these risk factors has led many national and local groups to develop clinical practice guidelines for management of CVD. Although the aim of such guidelines is to provide practitioners with a framework to identify, prioritize, and manage patients, the plethora of guidelines can cause confusion. In addition, research indicates that guidelines are not being optimally implemented. This review considers these practical issues, highlights the common goals shared by many guidelines, and focuses on how these can be best achieved. It also highlights areas where the guidelines differ and discusses points to consider when selecting the most appropriate recommendation.

Ethnic differences in mental health and lifestyle issues: results from multi-item general practice screening.

AIM: To determine ethnic differences in response, acceptance and desire to address problems identified by the multi-item screening tool (MIST). METHODS: Patients were assessed using the MIST in urban Auckland. Fifty consecutive adult patients from 20 randomly selected practices completed the MIST and evaluation sheet before their consultation. All patients and general practitioners (GPs) completed feedback forms. Analysis adjusted for the clustered nature of the data. RESULTS: Participants were 1000 patients and 20 urban GPs. The participation rate was 87% of GPs and 97.75% of patients. Compared with New Zealand Europeans, Pacific Island people were significantly more likely to be concerned about abuse and anger control. Maori were significantly more likely to want help with cutting down their alcohol use. The screening tool was accepted by all patients (<1% objection rate) regardless of ethnicity. DISCUSSION: This is the first study to examine possible ethnic differences between primary care patients' response to screening on lifestyle behaviours and mental health issues.

Few rural general practitioners use the Internet frequently in regard to patient care.

AIMS: To benchmark North Island rural general practitioner (GP) access to computers and the Internet, both at work and home, and assess whether rural GPs are using the Internet in regard to patient care. METHODS: Cross-sectional postal survey of all North Island rural GPs in mid-2003. RESULTS: 175 of 289 GPs (60.6%) returned useable questionnaires. Most (89.0%) reported computer availability at work when consulting, but even more had access to a computer at home (97.1%, p<0.01). Access to the Internet was also lower at work (68.6%) than at home (98.8%, p<0.01). Fewer GPs (p<0.05) reported ever using the Internet at work in regard to patients (56.5%) than at home (71.9%). Less than 10% of all GPs used the Internet three or more times a week at work (6.9%) or home (8.6%) in regard to patients. Of those with Internet access at work, 27.0% had broadband (fast Internet) access. Predictors of having (versus not having) work Internet access were computer availability in consultations (p=0.04). CONCLUSIONS: Few North Island rural GPs use the Internet frequently in regard to patient care, despite increasing access to computers and the Internet, both at work and home.

High rates of chlamydia in patients referred for termination of pregnancy: treatment, contact tracing, and implications for screening.

AIMS: To determine the rate of chlamydia and other sexually transmitted infections (STIs), and to describe treatment and factors associated with chlamydia in patients presenting for a termination of pregnancy (TOP). METHODS: A retrospective audit of patients attending one of two TOP clinics from 1 February 2003. (Clinic A, n=500; Clinic B, n=501). Age, ethnicity, marital status, previous pregnancies, contraception, STIs, and treatment were recorded. RESULTS: Ten percent of patients tested positive for an STI. Chlamydia was most commonly detected, in 7.7% of all patients. Higher rates of chlamydia were observed at clinic B (10.2% vs 5.2%, p=0.005) and in under 25 year olds (11.2% vs 3.6%, p<0.001). Rates of chlamydia in Pacific women were 18.6%, in Maori 12.9%, in Asian 7.3% and 4.4% in New Zealand European women. All patients testing positive for chlamydia were treated prior to TOP but only 41% of partners were treated. Other infections detected included 18 cases of human papillomavirus (HPV), three cases of trichomoniasis, one case of gonorrhoea, and one case of syphilis. CONCLUSIONS: There is a high rate of chlamydia in women presenting for TOP, particularly in under 25 year olds, Pacific, and Maori women. There is an immediate need for policymakers to respond to this increasing burden of chlamydia by instigating targeted education, guidelines, and mandatory chlamydia screening and contact tracing for pregnant women.

Patients and computers as reminders to screen for diabetes in family practice. Randomized-controlled trial.

BACKGROUND: In New Zealand, more than 5% of people aged 50 years and older have undiagnosed diabetes; most of them attend family practitioners (FPs) at least once a year. OBJECTIVES: To test the effectiveness of patients or computers as reminders to screen for diabetes in patients attending FPs. DESIGN: A randomized-controlled trial compared screening rates in 4 intervention arms: patient reminders, computer reminders, both reminders, and usual care. The trial lasted 2 months. The patient reminder was a diabetes risk self-assessment sheet filled in by patients and given to the FP during the consultation. The computer reminder was an icon that flashed only for patients considered eligible for screening. PARTICIPANTS: One hundred and seven FPs. MEASUREMENTS: The primary outcome was whether each eligible patient, who attended during the trial, was or was not tested for blood glucose. Analysis was by intention to treat and allowed for clustering by FP. RESULTS: Patient reminders (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.21, 2.43), computer reminders (OR 2.55, 1.68, 3.88), and both reminders (OR 1.69, 1.11, 2.59) were all effective compared with usual care. Computer reminders were more effective than patient reminders (OR 1.49, 1.07, 2.07). Patients were more likely to be screened if they visited the FP repeatedly, if patients were non-European, if they were "regular" patients of the practice, and if their FP had a higher screening rate prior to the study. CONCLUSIONS: Patient and computer reminders were effective methods to increase screening for diabetes. However, the effects were not additive.

Is physical activity counseling effective for older people? A cluster randomized, controlled trial in primary care.

OBJECTIVES: To establish the effectiveness of the Green Prescription physical activity counseling program in increasing activity and quality of life in older community-dwelling people. DESIGN: Post hoc subgroup analysis of a large cluster randomized, controlled trial. SETTING: One hundred seventeen doctors in 42 primary care practices (74% participation rate) in the Waikato region of New Zealand. PARTICIPANTS: Two hundred seventy sedentary primary healthcare patients aged 65 and older (67% participation rate). INTERVENTION: Patients in intervention practices prompted their primary care doctors or practice nurse to deliver brief activity counseling. A "Green Prescription" was written involving the negotiation of activity goals. Trained exercise specialists from a regional sports foundation gave follow-up telephone support over 3 months. MEASUREMENTS: Leisure moderate and vigorous physical activity, total energy expenditure, systolic and diastolic blood pressure, health-related quality of life, musculoskeletal injuries, falls, and hospitalizations. RESULTS: After 12 months of follow-up, leisure time moderate activity increased by 0.67 h/wk more in the intervention group than the control group (95% confidence interval (CI)=0.17-1.17) and energy expenditure increased by 2.67 kcal/kg per week (95% CI=0.87-4.47) more. For intervention group participants, vitality and general health scales of the 36-item Short Form showed statistically and clinically relevant improvements, and there was a decrease in hospitalizations (P<.03). There were no observable changes in blood pressure, injuries, or falls as a result of the Green Prescription program. CONCLUSION: This physical activity intervention improved activity, energy expenditure, health-related quality of life, and hospitalizations for older primary care patients. Systematic inclusion of the Green Prescription in routine primary health care will probably lead to health gain for older people.

N-of-1 trials of quinine efficacy in skeletal muscle cramps of the leg.

BACKGROUND: Skeletal muscle cramps affect over a third of the ambulatory elderly population. Quinine is the established treatment, but there are safety concerns, and evidence for efficacy is conflicting. A recent meta-analysis established a small advantage for quinine, but identified the need for additional studies. N-of-1 trials compare two treatments, in a randomised, double-blind, multiple crossover study on a patient-by-patient basis. They have been used to compare treatments in osteoarthritis and may be suitable for determining the individual efficacy of quinine. AIM: To establish efficacy and safety of quinine sulphate use for the treatment of leg-muscle cramp. DESIGN OF STUDY: Double-blind, randomised series of n-of-1 controlled trials of quinine versus placebo for muscle cramps. SETTING: New Zealand general practices. METHOD: The participants were 13 general practice patients (six males; seven females; median age = 75 years) already prescribed quinine. Following a 2-week washout, each patient received three 4-week treatment blocks of quinine sulphate and matched placebo capsules with an individual, randomised crossover design. The main outcome measures were: patient diaries of cramp occurrence, duration and severity; capsule counts; and blood quinine levels in the final treatment block. RESULTS: Ten patients completed the trial. Three patients were identified for whom quinine was clearly beneficial (P <0.05), six showed non-significant benefit and one showed no benefit. All patients elected to continue quinine post-study. CONCLUSION: Series of n -of-1 studies differentiated patients whom quinine had statistically significant effects; those with trend towards effectiveness; those for whom quinine was probably not effective. Ideally n-of-1 trial should be performed when a patient is commenced on quinine. More cycles in n-of-1 studies of quinine may address issues of statistical power.

Corticosteroid injections for painful shoulder: a meta-analysis.

BACKGROUND: There are no systematic reviews of corticosteroids for shoulder pain that calculate the numbers needed to treat. AIM: We wished to determine the effectiveness in terms of improvement of symptoms of intra-articular and subacromial injections of corticosteroid for rotator cuff tendonitis and frozen shoulder. DESIGN OF STUDY: Systematic review and meta-analysis of randomised controlled trials. METHOD: Data sources included the Cochrane Controlled Trials Register, Medline, EMBASE, hand searches and author contacts. The review methods required any randomised controlled trial in which the effectiveness of subacromial or intra-articular steroid injections versus placebo and versus non-steroidal anti-inflammatory medication, could be ascertained. The outcome was improvement of symptoms. The data abstraction was done independently, as was the validity assessment. The data was pooled using Review Manager 4.1. RESULTS: Seven studies were reviewed for corticosteroids versus placebo and three for corticosteroids versus nonsteroidal anti-inflammatory drugs (NSAIDs). The relative risk for improvement for subacromial corticosteroid injection for rotator cuff tendonitis was 3.08 (95% confidence interval [CI] = 1.94 to 4.87). The number needed to treat based on the pooled relative risk was 3.3 (95% CI = 1.8 to 7.7) patients to obtain one improvement. The relative risk for high dose (50 mg of prednisone or more) was 5.9 (95% CI = 2.8 to 12.6). The relative risk for improvement with steroids compared with NSAIDs was 1.43 (95% CI = 0.95 to 2.16). The number needed to treat for corticosteroids versus NSAIDs was 2.5 (95% CI = 1 to 9) for one significant study. The relative risks for intra-articular steroid injection for rotator cuff tendonitis were not statistically significant. CONCLUSION: Subacromial injections of corticosteroids are effective for improvement for rotator cuff tendonitis up to a 9-month period. They are also probably more effective than NSAID medication. Higher doses may be better than lower doses for subacromial corticosteroid injection for rotator cuff tendonitis.

Cost-effectiveness of physical activity counselling in general practice.

AIM: To assess the cost-effectiveness of the 'Green Prescription' physical activity counselling programme in general practice. METHOD: Prospective cost-effectiveness study undertaken as part of a cluster randomised controlled trial with 12-month follow-up of 878 'less-active' patients aged 40-79 years in 42 general practices in the Waikato. The intervention was verbal advice and a written exercise prescription given by general practitioners, with telephone exercise specialist follow-up compared with usual care. Main outcome measures included cost per total and leisure-time physical activity gain from health-funders' and societal perspectives. RESULTS: Significant increases in physical activity were found in the randomised controlled trial. Programme-cost per patient was NZ170 dollars from a funder's perspective. The monthly cost-effectiveness ratio for total energy expenditure achieved was 11 dollars per kcal/kg/day. The incremental cost of converting one additional 'sedentary' adult to an 'active' state over a twelve-month period was NZ1,756 dollars in programme costs. CONCLUSION: Verbal and written physical activity advice given in general practice with telephone follow-up is an inexpensive way of increasing activity for sedentary people, and has the potential to have significant economic impact through reduction in cardiovascular and other morbidity and mortality.

Lifestyle screening: development of an acceptable multi-item general practice tool.

AIMS: To develop a short screening tool for lifestyle and mental-health risk factors that adults can self-administer, and to determine acceptability and feasibility of use of this tool in primary care settings. METHODS: The multi-item tool was designed to screen patients in rural and urban New Zealand general practices for smoking, alcohol and drug misuse, problem gambling, depression, anxiety, abuse, anger, sedentary lifestyle, and weight issues. Patients were offered help for identified risk factors. Fifty consecutive adult patients per practice (n=2,543) were recruited to participate from 20 randomly-selected urban general practitioners; 20 general practice nurses and 11 rural general practitioners. RESULTS: Patients came from diverse ethnic, geographical, and socioeconomic backgrounds. The sample prevalence of positive responses identified ranged from 2.8% (gambling) to 42.7% (depression). The number of patients requesting immediate assistance with these responses (0.5 to 13.5%) did not overwhelm clinicians. The tool was well accepted by patients, with few objections to specific questions (0.1-0.8%). Most practitioners stated they will use the screening tool once available. CONCLUSIONS: Screening for lifestyle and mental health risk factors is becoming increasingly important in primary health care. This screening tool was acceptable to patients and was not considered overly burdensome by practitioners.

Corticosteroid injections for osteoarthritis of the knee: meta-analysis.

OBJECTIVES: To determine the efficacy of intra-articular corticosteroid injections for osteoarthritis of the knee and to identify numbers needed to treat. DATA SOURCES: Cochrane controlled trials register, Medline (1966 to 2003), Embase (1980 to 2003), hand searches, and contact with authors. INCLUSION CRITERIA: Randomised controlled trial in which the efficacy of intra-articular corticosteroid injections for osteoarthritis of the knee could be ascertained. RESULTS: In high quality studies, the pooled relative risk for improvement in symptoms of osteoarthritis of the knee at 16-24 weeks after intra-articular corticosteroid injections was 2.09 (95% confidence interval 1.2 to 3.7) and the number needed to treat was 4.4. The pooled relative risk for improvement up to two weeks after injections was 1.66 (1.37 to 2.0). The numbers needed to treat to get one improvement in the statistically significant studies was 1.3 to 3.5 patients. CONCLUSION: Evidence supports short term (up to two weeks) improvement in symptoms of osteoarthritis of the knee after intra-articular corticosteroid injection. Significant improvement was also shown in the only methodologically sound studies addressing longer term response (16-24 weeks). A dose equivalent to 50 mg of prednisone may be needed to show benefit at 16-24 weeks.

Diabetes care: practice nurse roles, attitudes and concerns.

BACKGROUND: Practice nurses (PNs) are the largest group of nurses providing primary care for patients with diabetes in New Zealand, and changes in the health system are likely to have a substantial effect on their roles. To inform the development of a new primary health care nursing structure and evaluate the new role associated with this, it will be important to have data on current practice nurse roles. AIMS: The aim of this paper is to report a study to compare the diabetes-related work roles, training and attitudes of practice nurses in New Zealand surveyed in 1990 and 1999, to consider whether barriers to practice nurse diabetes care changed through that decade, and whether ongoing barriers will be addressed by current changes in primary care. METHODS: Questionnaires were mailed to all 146 PNs in South Auckland in 1990 and to all 180 in 1999, asking about personal and practice descriptions, practice organization, time spent with patients with diabetes, screening practices, components of care undertaken by practice nurses, difficulties and barriers to good practice, training in diabetes and need for further education. The 1999 questionnaire also asked about nurse prescribing and influence on patient quality of life. RESULTS: More nurses surveyed in 1999 had postregistration diabetes training than those in 1990, although most of those surveyed in both years wanted further training. In 1999, nurses looked after more patients with diabetes, without spending more time on diabetes care than nurses in 1990. Nevertheless, they reported increased involvement in the more complex areas of diabetes care. Respondents in 1999 were no more likely than those in 1990 to adjust treatment, and gave a full range of opinion for and against proposals to allow nurse prescribing. The relatively low response rate to the 1990 survey may lead to an underestimate of changes between 1990 and 1999. CONCLUSIONS: Developments in New Zealand primary care are likely to increase the role of primary health care nurses in diabetes. Research and evaluation is required to ascertain whether this increasing role translates into improved outcomes for patients.

Contraception before and after termination of pregnancy: can we do it better?

AIM: To compare contraceptive use pre- and post-therapeutic abortion in 1995, 1999 and 2002 in a New Zealand clinic. METHODS: Retrospective, consecutive case review of women presenting for therapeutic abortion. Anonymous data included demographic details, contraception used at conception, and post-termination contraception. RESULTS: Pre-conception contraceptive use is significantly declining, with post-termination condom choice increasing. This is predominantly due to increasing numbers of Asian women presenting for abortion. In 2002, 97% of Asian women used no contraception or only condoms pre-conception, and 62% chose condoms or abstinence post-termination. Oral contraceptives are used significantly less by Asian than European women both pre-termination (p = 0.0002) and post-termination (p = 0.00001). Other ethnic groups showed little change in contraceptive use over the study periods. CONCLUSIONS: It is speculated that ethnic Chinese women lack adequate contraceptive education, demonstrate distrust of non-barrier methods, believe men should provide the prophylactic, and mistakenly believe contraception unnecessary for the first week following menstruation. Abortion may be used for family planning rather than as back up for contraceptive failure. Young Chinese arriving in New Zealand require immediate sexual health education including accurate contraceptive information. Liaison between primary healthcare sectors and policy makers of immigration and other services assisting overseas students is recommended to provide culturally appropriate education.
