Preventive dentistry: what do Australian patients endorse and recall of smoking cessation advice by their dentists?

OBJECTIVE: To investigate patients' views regarding dentists' smoking cessation advice. DESIGN: Survey questionnaire. SETTING: One hundred and thirty five dental practices in Sydney Australia. Subjects Two thousand, four hundred and fifty one dental patients. RESULTS: One thousand, one hundred and sixty pre-consultation questionnaires were obtained (RR=80%), 302 (26%) were self-reported smokers. From these, 623 post-consultation questionnaires were returned (RR = 54%). Most patients expected dentists to be interested in their smoking status (n = 847/1160, 73%, 95% CI: 70% to 76%) and to discuss smoking with them (n = 713/1160, 61%, 95% CI: 59% to 64%), however, smokers were significantly less likely to respond as such compared with non-smokers (P < 0.001). Smokers and non-smokers equally would not change dentist even if asked about their smoking status opportunistically (59% versus 62%) (OR = 0.91, 95% CI: 0.67 to 1.22). Less than one third of all smokers would try to quit if their dentist suggested they do so (n = 90/302, 30%, 95% CI: 25% to 35%). Smokers' recall of quit advice from their recent consultation was low (n = 22/124, 18%). CONCLUSIONS: Smoking cessation advice by dentists is not self-evidently effective. These findings behove interventional research to ascertain efficacy of smoking cessation advice delivered by dentists before admonishing changes in routine clinical practice.

Impact of increasing the re-supply interval on the seasonality of subsidised prescription use in Australia.

OBJECTIVE: To evaluate the impact of increasing the minimum re-supply period for prescriptions on the Pharmaceutical Benefits Scheme (PBS) in November 1994. The intervention was designed to reduce the stockpiling of medicines used for chronic medical conditions under the PBS safety net. METHODS: Interrupted times series regression analyses were performed on 114 months of PBS drug utilisation data from January 1991 to June 2000. These analyses assessed whether there had been a significant interaction between the onset of the intervention in November 1994 and the extreme levels of drug utilisation in the months of December (peak utilisation) and January (lowest utilisation) respectively. Both serial and 12-month lag autocorrelations were controlled for. RESULTS: The onset of the intervention was associated with a significant reduction in the December peak in drug utilisation; after the introduction of the policy there were 1,150,196 fewer prescriptions on average for that month (95% CI 708,333-1,592,059). There was, however, no significant change in the low level of utilisation in January. The effect of the policy appears to be decreasing across successive post-intervention years, though the odds of a prescription being dispensed in December remained significantly lower in 1999 compared to each of the pre-intervention years (11% vs. 14%). CONCLUSION: Analysis of the impact of increasing the re-supply period for PBS prescriptions showed that the magnitude of peak utilisation in December had been markedly reduced by the policy, though this effect appears to be decreasing over time. Continued monitoring and policy review is warranted in order to ensure that the initial effect of the intervention be maintained.

Instructions for ambulatory surgery--patient comprehension and compliance.

Ambulatory surgery has proliferated as a result of increasing inpatient costs. Its high level of safety has resulted in its extension to less healthy, often elderly patients. Patient compliance with instructions is essential to avoid morbidity. We aimed to identify subgroups potentially at risk due to non-compliance. A confidential questionnaire was administered to 220 consecutive daycase patients. Data included: patient demographics, duration of fasting, taking of medications that morning, importance of fasting and medication instructions, mode of post-discharge transport, and whether they had someone to stay with them that night. Seven (3.5 per cent) patients admitted to non-compliance with fasting instructions, with 8 per cent considering these instructions non-essential. Thirteen of 59 patients on medications took them against instructions, with 9 patients considering the instructions non-essential. Eight patients admitted intending to drive home; 7 per cent admitted to having no one to stay with them on the night of surgery. A significantly minority of patients (particularly male) admit to non-compliance with ambulatory surgery instructions; these figures may be underestimates. Absence of anaesthetic/medical input and lack of reinforcement probably contribute to non-compliance. Some medication-related non-compliance may be appropriate (e.g. antianginals, antihypertensives) and may reflect conflicting instructions given to the patient. The stopping of all medications prior to ambulatory surgery needs revision. Older patients living alone may not be suitable candidates for ambulatory anaesthesia.

Impact in general practice of the policies of the organised approach to preventing cancer of the cervix.

This cross-sectional survey of cancer screening in May 1996 used a national random sample of a specified group of general practitioners (GPs). The survey included items to assess the impact of the Organised Approach to the Prevention of Cervical Cancer (OAPCC). Of the 1,271 GPs who satisfied the eligibility criteria, 855 (67%) returned a completed questionnaire. Fifty-two per cent indicated they would be 'highly' likely to introduce a discussion about cervical smears to a 58-year-old woman who was in good health and had come for a non-gynaecological consultation. Female sex, RACGP affiliation, practising in a metropolitan area and awareness of the OAPCC booklet were independent predictors of an opportunistic orientation. By contrast, 91% indicated that they would be 'highly' likely to include a Pap smear in a general health checkup. Thirty-eight per cent reported that they had found the booklet about the 1991 screening policy 'very' useful, while 38% found the NHMRC guidelines for the management of women with screen detected abnormalities 'very' useful. Around one-fifth of the GPs were not aware of these documents. Overall, 19% still recommended annual or more frequent screening. GPs from NSW and Queensland were less likely to support biennial screening than GPs from other states. Overall, 26% of GPs did not indicate that they would refer a woman who had tested positive for any grade of CIN for colposcopic assessment. Female GPs were more likely to refer women with CIN for colposcopic assessment while older doctors were less likely to do so.

Is there gender bias in research fellowships awarded by the NHMRC?

OBJECTIVE: To assess whether there is gender bias in the allocation of research fellowships granted by the Research Fellowships Committee of the National Health and Medical Research Council. DATA SOURCES: Anonymous data from applications for a research fellowship from 1994 to 1997. RESULTS: More men than women apply for research fellowships (sex ratio, 2.5:1), but there is no difference in the proportion of male or female applicants who succeed in their application. Among new applicants, men tend to apply for a higher level of fellowship than women. CONCLUSIONS: Lack of data about the numbers of eligible men and women means that we cannot draw conclusions about self-selection biases among potential applicants. However, the selection procedures of the Committee appear to be unbiased. The gender of applicants does not influence the outcome of their application.
