Gonorrhoea screening in general practice: perceived barriers and strategies to improve screening rates.

OBJECTIVE: To investigate perceived barriers to gonorrhoea screening in general practice and suggest strategies to overcome them. DESIGN: Questionnaire-based survey. SETTING AND PARTICIPANTS: All 47 general practitioners (GPs) authorised to prescribe subsidised HIV drugs under the Pharmaceutical Benefits Scheme in inner, eastern and northern Sydney. MAIN OUTCOME MEASURES: Agreement on a five-point Likert scale with statements about attitudes and practices in relation to gonorrhoea screening of homosexually active men, and views on how testing rates could be increased. RESULTS: 32 GPs responded (68%). Perceived barriers to gonorrhoea testing included structural measures imposed by the Federal Government to limit pathology testing by GPs (the Medicare "three-test rule") (17 respondents agreed or strongly agreed), pressure from the Health Insurance Commission (HIC) to minimise pathology testing (15), concerns about confidentiality of notification procedures (8), clinical time pressure (8), and concerns about recriminations against HIV patients with gonorrhoea (6). Suggested measures to increase testing were education of gay men to request testing (25), relaxation of the three-test rule (25), easier tests (23), anonymous notification procedures, review of HIC policy on screening, and training about testing (21 each). CONCLUSIONS: Sydney GPs with high HIV caseloads perceived structural barriers to gonorrhoea testing and supported a range of achievable strategies to overcome these. As the sustained epidemic of gonorrhoea in Sydney may be directly promoting HIV transmission, these strategies should be considered urgently.     

Effect of health visitors working with elderly patients in general practice: a randomised controlled trial

Health visitors were employed specifically to care for two years for a random sample of patients in general practice who were aged over 70. Independent assessments made at the beginning and end of the study showed that the health visitor in an urban practice had some impact on her caseload of patients; she provided more services for them, their mortality was reduced, and their quality of life improved, though the last measure just failed to be statistically significant. The health visitor working in a rural practice had no such effect.     

Screening for Chlamydia trachomatis at the time of routine Pap smear in general practice: a cluster randomised controlled trial

OBJECTIVE: To determine whether asking general practitioners to offer chlamydia screening at the same time as Pap screening increases chlamydia screening rates. DESIGN: A pragmatic cluster randomised controlled trial. PARTICIPANTS AND SETTING: Doctors from 31 general practices in the Australian Capital Territory performing more than 15 Pap smear screens per year, and all women aged 16-39 years attending those practitioners between 1 November 2004 and 31 October 2005. INTERVENTION: Doctors in the intervention practices were asked to routinely offer combined chlamydia and Pap screening to eligible women; doctors in the control practices were asked to implement screening guidelines based on a risk assessment of the individual patient (ie, usual practice). MAIN OUTCOME MEASURE: Chlamydia screening rate per visit. RESULTS: There were 26 876 visits by eligible women during the study period: 16 082 to intervention practices and 10 794 to control practices. Chlamydia screening occurred during 6.9% (95% CI, 6.5%-7.3%) of visits to intervention practices and 4.5% (95% CI, 4.1%-4.9%) of visits to control practices. After controlling for clustering and potential confounders, there were twofold greater odds of chlamydia screening occurring during a visit by an eligible woman to an intervention practice than to a control practice (adjusted odds ratio, 2.1 [95% CI, 1.3-3.4]). CONCLUSION: Combining chlamydia and Pap screening increases the rate of chlamydia screening in general practice. Implementing this approach would require little additional infrastructure support in settings where a cervical screening program already exists.     

Investigation and management of iron deficiency anaemia in general practice: a cluster randomised controlled trial of a simple management prompt

Background: Iron deficiency anaemia (IDA) remains the most common cause of anaemia and is frequently secondary to occult gastrointestinal blood loss requiring further investigation. The study was designed to prospectively assess the adequacy of investigation of IDA and to establish whether a simple computerised prompt would increase the completeness of investigation of patients presenting to their general practitioners. Patients and methods: All men aged >20 and women aged >50 newly found to have a probable IDA (n=431) in primary care were randomised according to general practice (n=89) to one of two computer generated prompts, by the haematology laboratories in two large district general hospitals. Data were collected 12 months after the index date. The primary outcome measure was the adequacy of investigation of the cause of anaemia. Multiple logistic regression was used to analyse each binary outcome. Results: Two hundred and three (47%) of 431 patients presenting to their general practitioner with an IDA were adequately managed and 140/357 (39%) of patients who were otherwise fit for investigation had no tests at all. Twenty one (17%) of 125 patients who did have adequate investigation at the time of presentation were found to have colorectal cancer. Only 30% of patients had a confirmed diagnosis within 12 months. The prompt did not affect the level of investigation (odds ratio 0.88, 95% confidence interval (CI) 0.60 to 1.29, p=0.52). The initial prescribing of oral iron was improved (odds ratio 2.19, 95% CI 1.27 to 3.77, p=0.005), but not the documented prescribing of a full therapeutic course or the use of follow up blood counts. Conclusions: The investigation and management of IDA presenting in general practice remains inadequate and is not improved by a simple management prompt.     

Shared care through divisions of general practice: moving forward.

Divisions of general practice have established a wide variety of structured programs to support shared care over the past six years. Differences in the adoption and continuation of these programs appear to be related to a number of factors, including local opportunities and external funding and demands on divisions, relationships and the capacity of the divisions and their health service partners.     

Encouraging attendance at screening mammography: knowledge, attitudes and intentions of general practitioners

We surveyed a random sample of 200 general practitioners from the Sydney metropolitan area about their attitudes to and knowledge of screening mammography. General practitioners' knowledge about some aspects of screening mammography was found to be limited; only 25% of the sample knew that the risk of breast cancer increases with age and only 30% of the sample knew that the evidence for a reduction in mortality as a result of mammographic screening is weakest for women of less than 50 years of age. Ninety-five per cent of general practitioners were of the opinion that breast self-examination and clinical examination were important for asymptomatic women of more than 45 years of age compared with the 75% of respondents who viewed mammography in the same way. Scores on a scale that was constructed to measure attitudes to mammographic screening showed that 20% of general practitioners had a "very favourable" attitude, and that a further 67% of general practitioners had a "favourable" attitude. No general practitioners had a "very unfavourable" attitude. Eighty-four per cent of general practitioners indicated that they would recommend that their patients attend a free screening-mammography service. Willingness to recommend mammographic screening was predicted by a general practitioner's attitude score. The strongest component of this prediction was a belief that the benefits of screening mammography outweighed the radiation risks. General practitioners need to be supplied with correct information about target groups for screening, so that women in the appropriate age-groups are encouraged to attend screening programmes.     

Acceptance of a psychiatric screening questionnaire by general practice attenders

The general health questionnaire (GHQ) is a self-reporting psychiatric screening questionnaire which has been tested and validated in a number of languages and cultural settings. The translated and validated 30 item GHQ was given to a selected sample of women between 15 and 49 years attending a suburban general practice, as a part of a study on emotional disorder. The acceptance of the questionnaire was high with a compliance of 91.5% from those who were invited to participate. The majority of respondents showed much interest and willingness in filling in the questionnaire.     

A Quality Use of Medicines program for general practitioners and older people: a cluster randomised controlled trial

OBJECTIVE: To investigate the effectiveness of an educational Quality Use of Medicines program, delivered at the level of general practice, on medicines use, falls and quality of life in people aged > or = 65 years. DESIGN: Cluster randomised controlled trial conducted in 2002. SETTING: General practices in the Hunter Region, New South Wales, Australia. PARTICIPANTS: Twenty general practitioners recruited 849 patients to participate in the study. INTERVENTION: Education (academic detailing, provision of prescribing information and feedback); medication risk assessment; facilitation of medication review; financial incentives. MAIN OUTCOME MEASURES: Primary measures: a composite score reflecting use of benzodiazepines, non-steroidal anti-inflammatory drugs (NSAIDs) and thiazide diuretics; secondary measures: use of medication reviews, occurrence of falls, quality of life (as assessed by SF-12 and EQ-5D survey scores. RESULTS: Compared with the control group, participants in the intervention group had increased odds of having an improved medication use composite score (odds ratio [OR], 1.86; 95% CI, 1.21-2.85) at 4-month follow-up but not at 12 months. At 4-month follow-up, the intervention group had reduced odds of using NSAIDs (OR, 0.62; 95% CI, 0.39-0.99) and showed a non-significant reduction in use of benzodiazepines (OR, 0.51; 95% CI, 0.20-1.30) and thiazide diuretics (OR, 0.70; 95% CI, 0.48-1.01). Changes in drug use were not significant at 12-month follow-up. At 12 months, intervention-group participants had lower adjusted ORs (AORs) for having a fall (AOR, 0.61; 95% CI, 0.41-0.91), injury (AOR, 0.56; 95% CI, 0.32-0.96), and injury requiring medical attention (AOR, 0.46; 95% CI, 0.30-0.70). Quality-of-life scores were unaffected by the intervention. CONCLUSION: Education and systems for medication review conducted by GPs can be used to improve use of medicines. These interventions are associated with a reduction in falls among older people, without adverse effects on quality of life.     

Age-sex registers as a screening tool for general practice: size of the wrong address problem

Age-sex registers were compiled and updated for the east London general practices participating in a screening study for hypertension. Of 1435 addresses in the registers of two practices that were checked, 228 (16%) were incorrect, according to the return by the post office of the screening invitations and checking the addresses of the non-responders using telephone directories and the medical records. The non-responders to the screening invitation for whom a new address was not found, were visited at the address as recorded on the age-sex register. This showed that the true address error rate from the original age-sex registers was 26% and thus substantially greater than that calculated from returned letters. It is concluded that the non-acceptance rate of screening in general practice might be exaggerated as a result of the lack of a correct address for a substantial proportion of the patients on a general practice list.     

The effectiveness of invitations from general practitioners in recruiting women to mammographic screening

OBJECTIVE: To evaluate the effectiveness of general practitioner patient lists as a means of recruiting women to mammography screening. DESIGN: This study constitutes the first part of a comparative study of two alternative recruitment strategies involving invitation of women identified from: (i) general practitioner lists; and (ii) the electoral roll. SETTING AND SUBJECTS: The subjects were women aged 50-64 listed as patients of the first three private practices that agreed to collaborate with the South Australian (SA) Breast X-Ray Service to recruit by this method. These practices include five locations encompassing a spread of middle and upper class socioeconomic areas in Adelaide's southern suburbs. INTERVENTIONS: In all, 1505 women who had not already attended the SA Breast X-Ray Service were sent a letter of invitation by their general practitioner to attend the Service for a screening mammogram at a specified date and time. MAIN OUTCOME MEASURES: The primary outcome measures were eligibility status (eligible, not eligible) and attendance status (attended, cancelled appointment, failed to attend without notice). RESULTS: Excluding 34 letters that were returned unopened, 10% of invitees were classified as not eligible, mostly because they had had a recent mammogram elsewhere. Of the remaining invitees, 68.6% attended, 8.4% rang to cancel the appointment and 23% failed to attend without prior notice. CONCLUSIONS: This method of recruitment is viable, and it yields high participation rates close to the "Health for All Australians" target of 70% for mammography screening. Furthermore, the actual attendance rate for this population is expected to increase over time, because some of those initially classified as ineligible, or who cancelled or failed to attend, eventually will attend. The success of this method of recruitment will be measured against the relative cost and effectiveness of the electoral roll alternative, currently under investigation by the SA Breast X-Ray Service.     

Cervical cytology screening: experience of a general hospital.

At Henderson General Hospital, Hamilton, a program was introduced whereby cervical smears were taken routinely for cytologic study from all women admitted aged 17 years or older. The procedure was performed by a specially trained nurse. In a 5-year period 53% of eligible patients were screened. Of these, 32% had not had a cervical smear taken before. In 7681 smears nine instances of invasive disease were discovered: three of the cervix, three of the endometrium and three metastatic. There were 20 cases of carcinoma in situ and 2 of severe dysplasia. Evidence of infection was present in a high percentage of the smears. Hospital admission affords an excellent opportunity of applying this valuable screening procedure.     

Dyspepsia: incidence of a non-ulcer disease in a controlled trial of ranitidine in general practice

Patients who presented to their family doctors with previously uninvestigated dyspepsia of at least two weeks' duration were recruited into a placebo controlled trial of treatment with ranitidine (150 mg twice daily) for six weeks. All patients were examined by endoscopy before treatment, and for those with macroscopical abnormalities the examination was repeated after treatment. Of the 604 patients recruited, 559 had endoscopy, of whom 171 (30%) had no apparent abnormality. Of the 388 patients remaining, one third had two or more lesions. The high incidence of underlying disease was coupled with low accuracy in unaided clinical diagnosis. After endoscopy 496 patients with persistent symptoms (median duration six to eight weeks) were randomly allocated to treatment and then reviewed every two weeks. Complete remission of symptoms occurred in 76% of patients who were taking ranitidine and in 55% who were taking placebo (p less than 0.000004). Of those with non-ulcer dyspepsia, significantly more became symptom free taking ranitidine compared with placebo (p less than 0.002). Ranitidine healed most duodenal ulcers (80%) and gastric ulcers (90%) within four weeks. Tolerance to ranitidine was good, and the incidence of complaints was similar on placebo.     

Identification and treatment of risk factors for coronary heart disease in general practice: a possible screening model

A screening programme for the identification of risk factors for coronary heart disease in all patients aged 25-55 years in a general practice population was studied. The identification of risk factors included measurement of obesity, blood pressure, hypercholesterolaemia, and urinalysis, together with questions about family history, cigarette smoking, alcohol intake, and lifestyle. The patients with identified risk factors were invited to attend a lifestyle intervention clinic organised by the practice nurses and run by the health visitors, with the help of the local authority dietitian. Of 2646 (62%) patients who attended for screening, 78 (64%) of the 121 shown to have a high cholesterol concentration experienced a drop in cholesterol concentration. The mean fall in cholesterol concentration in the 78 patients who showed a positive response to intervention was 1.1 mmol/l. The study was intended as a possible flexible model for screening for coronary heart disease in general practice that could be complemented rather than replaced by opportunistic screening. The issues of organisation, cost, manpower, nonattendance, and effectiveness in a busy general practice environment are discussed.
