Effect of the addition of a "help" question to two screening questions on specificity for diagnosis of depression in general practice: diagnostic validity study.

OBJECTIVE: To determine the validity of two written screening questions for depression with the addition of a question inquiring if help is needed. DESIGN: Cross sectional validation study. SETTING: 19 general practitioners in six clinics in New Zealand. PARTICIPANTS: 1025 consecutive patients receiving no psychotropic drugs. MAIN OUTCOME MEASURES: Sensitivity, specificity, and likelihood ratios of the two screening questions, the help question, combinations of the screening and help questions, and diagnosis by general practitioners. RESULTS: The help question alone had a sensitivity of 75% (95% confidence interval 60% to 85%) and a specificity of 94% (93% to 96%). The positive likelihood ratio for the help question was 13.0 (9.5 to 17.8) and the negative likelihood ratio was 0.27 (0.17 to 0.44). The likelihood ratio for patients wanting help today was 17.5 (11.8 to 31.9). The general practitioner diagnosis had a sensitivity of 79% (65% to 88%) and a specificity of 94% (92% to 95%). CONCLUSION: Adding a question inquiring if help is needed to the two screening questions for depression improves the specificity of a general practitioner diagnosis of depression.

Rehabilitation after arthroscopic meniscectomy: a critical review of the clinical trials.

We reviewed the literature on patient management following arthroscopic meniscal surgery. A critical appraisal of the literature produced 8 randomized controlled trials evaluating the use of non-steroidal anti-inflammatory drugs or various forms of physiotherapy and pain control. Different treatments and outcome measures precluded meta-analysis. The limited evidence suggests that this is a relatively pain-free procedure with rapid recovery, and that in most cases simple analgesia in the first 1-2 days following surgery and a well-planned home-based exercise program should be sufficient. It is possible that routine daily non-steroidal anti-inflammatory drugs post-operatively for 3-6 weeks may enhance recovery rates. One study found that physiotherapy was beneficial for regaining muscle strength and on pain assessment but this did not translate into functional improvement. Descriptive studies are required to ascertain the types and duration of treatments being offered to patients after arthroscopic meniscectomy. Further research is needed to perform well-designed studies of current treatments that take into account predisposing factors and their impact on outcome, including use of prerandomization and real-life functional outcome measures.

Power issues in the doctor-patient relationship.

Power is an inescapable aspect of all social relationships, and inherently is neither good nor evil. Doctors need power to fulfil their professional obligations to multiple constituencies including patients, the community and themselves. Patients need power to formulate their values, articulate and achieve health needs, and fulfil their responsibilities. However, both parties can use or misuse power. The ethical effectiveness of a health system is maximised by empowering doctors and patients to develop 'adult-adult' rather than 'adult-child' relationships that respect and enable autonomy, accountability, fidelity and humanity. Even in adult-adult relationships, conflicts and complexities arise. Lack of concordance between doctors and patients can encourage paternalism but may be best resolved through negotiated care. A further area of conflict involves the 'double agency' of doctors for both patients and the community. Empowerment of all players is not always possible but is most likely where each party considers and acknowledges power issues.

Coping strategies in the self-management of chronic heart failure.

BACKGROUND: A patient's psychological adaptation to heart failure can influence its impact on his or her life. However, attempts to understand how patients cope mentally with severe emotional strain have led to inconsistent use of a plethora of concepts, making communication and clinical care difficult. OBJECTIVES: The aim of the present study was to develop a framework for conceptualizing how patients with chronic heart failure cope mentally with their illness, and then use the framework to suggest how GPs can facilitate patient self-care. METHODS: We systematically reduced and reassembled the narrative texts of personal, semi-structured interviews until their interpretation was complete. The interviews were conducted during late 1999 with 62 heart failure patients under GP care in 30 practices across central Auckland, New Zealand. RESULTS: Our framework describes four coping strategies: avoidance, disavowal, denial and acceptance. Disavowal provides a distinct coping strategy through which patients, who basically understand the threat to their life situations, seek hope through positively reconstructing this threat. Use of this strategy was highly salient regardless of patients' age, the length of time since their recorded diagnosis or the degree of self-reported limitation of recent physical function due to heart failure. Only over age 70 were avoidance and acceptance also highly salient among patients whose heart failure was diagnosed at least 3 years previously and had mildly limited their recent physical function. CONCLUSION: Many different heart failure patients use disavowal to palliate the emotional strain and find hope. Disavowal is not a problem to deal with but a process GPs can facilitate by implementing a range of suggested strategies through methods such as story telling.

Health and safety issues pertaining to genetically modified foods.

Genetic modification involves the insertion of genes from other organisms (within or between species) into host cells to select for desirable qualities. Potential benefits of GM foods include increased nutritional value; reduced allergenicity; pest and disease-resistance; and enhanced processing value. Possible detrimental outcomes include producing foods with novel toxins, allergens or reduced nutritional value, and development of antibiotic resistance or herbicide-resistant weeds. Benefits to individuals or populations need to be weighed against adverse health and environmental risks, and may differ between developing and Westernised countries. Whether testing and monitoring should exceed requirements for conventional foods is under debate. While not necessarily scientifically justifiable, consumer concerns have resulted in Australian and New Zealand requirements to label foods containing GM-produced proteins. Dissatisfied consumer advocacy groups are calling for all foods involving GM technology to be labelled, irrelevant of whether the final product contains novel protein. Goals to improve the quantity, quality and safety of foods are laudable; however, the primary aim of the bio-food industry is financial gain. GM foods may be as safe as conventional foods but public distrust runs high. It is important that discussion is informed by science and that claims of both benefits and risks are evidence-based, to ensure that the process is driven neither by the vested interest of the bio-technical multinational companies on the one hand, nor ill-informed public fears on the other.

General practitioner management of upper respiratory tract infections: when are antibiotics prescribed?

AIM: To assess General Practice (GP) description and management of upper respiratory tract infections (URTI), including conditions under which they prescribe antibiotics. METHOD: A telephone survey of a randomised sample of Auckland GPs. RESULTS: There was a 61% response rate. 82 of the 100 GPs interviewed agreed that most patients presenting with URTI expected antibiotics. Persistent symptoms and indication of specific infection (tonsillitis, otitis media, sinusitis, pharyngitis, purulent sputum) were common reasons for prescribing. Patients travelling overseas, expecting or requesting antibiotics and prior use of over-the-counter (OTC) medications increased antibiotic prescribing-rates. Most GPs (95%) issued as-needed prescriptions on occasion; 13% did this often. Amoxicillin and amoxicillin/clavulanic acid were most commonly used. Despite wide-ranging antibiotic use for URTI (0 to 90%), only 6% of GPs felt they prescribed more antibiotics than others. CONCLUSIONS: The results suggest over-prescription is common-place, but use of as-needed prescriptions to reduce antibiotic use is encouraging. Exploration of patient expectations in the consultation may assist in decreasing prescribing rates.

The early experience of general practitioners using Green Prescription.

AIM: Sedentary lifestyle is a significant risk factor for increased morbidity and mortality in many medical conditions. A Hillary Commission initiative, Green Prescription is a written exercise prescription given by general practitioners (GPs) to sedentary patients to encourage physical activity. Our aim was to establish the extent to which GPs in the North Health region in 1997 issued with Green Prescription packages had used them, the circumstances under which they were used, and barriers to their use. METHODS: 433 GPs issued with packs were faxed a one-page questionnaire for immediate completion, with follow-up of non-responders. RESULTS: The response rate was 73%, with 65% of respondents having written Green Prescriptions. Their main reasons for use were patient need for more exercise and presence of high-risk medical conditions such as hypertension, cardiovascular disease, obesity and diabetes. Reasons for non-use were: GP already giving advice about physical activity; concern that Green Prescription was patronising and simplistic; compliance issues and time restraints. Some requested a computerised version. CONCLUSION: Non-responders may be non-users, hence we estimate that 48-65% of targeted GPs used Green Prescription. Barriers identified by GPs have assisted in Green Prescription development, which is now nationwide and assessed by independent researchers tri-annually.
