Appropriateness in health care: application to prescribing.

To help account for and address observed variations in medical practice, evaluations of "appropriateness" have sought to supplement incomplete evidence with professional opinion. This article contributes to an understanding and refinement of the construct of appropriateness by discussing how it has been defined and applied in studies of health care in general and prescribing in particular. We suggest that appropriateness is the outcome of a process of decision-making that maximises net individual health gains within society's available resources. This definition distinguishes between (in)appropriate prescribing, as an outcome, and (ir)rational prescribing as a process. To assess appropriateness, we advocate combining explicit criteria with independent review in cases of uncertainty and disagreement. Refinements based on reviews using implicit criteria should draw on shared professional knowledge and post hoc state the process followed as explicitly as possible. The Medication Appropriateness Index is shown to provide a solid foundation for identifying dimensions of prescribing appropriateness.

Skin prick testing in general practice: a pilot study.

Allergy skin prick testing is regarded as a routine diagnostic procedure in hospital settings, but its role in general practice is not yet defined. Our aim was to explore the ways in which skin prick testing might facilitate the work of general practice nurses engaged in asthma patient care. A structured questionnaire was completed by 18 practice nurses before and again after administering allergy skin tests to four common aeroallergens (dust mite, grass pollen, cat and dog danders) to 319 consecutive attenders with known or suspected asthma. Nurses' decisions about whether or not to give allergen avoidance advice were reversed after skin testing in 63 (22%) cases for dust mite, 67 (23%) cases for grass pollen, 38 (13%) cases for cat fur and 49 (17%) cases for dog hair. Had allergen avoidance interventions been targeted only at patients with both a positive skin test and a positive clinical history, the number of planned interventions would have declined from 305 before skin testing to 142 after. The findings suggest that allergy skin prick testing was feasible and acceptable in general practice, and that one role may be to reduce the number of allergen avoidance interventions offered to patients unlikely to benefit.

Worldwide variations in prevalence of symptoms of allergic rhinoconjunctivitis in children: the International Study of Asthma and Allergies in Childhood (ISAAC).

BACKGROUND: As part of the International Study of Asthma and Allergies in Childhood (ISAAC), prevalence surveys were conducted among representative samples of school children from locations in Europe, Asia, Africa, Australia, North and South America. SUBJECTS: 257,800 children aged 6-7 years from 91 centres in 38 countries, and 463,801 children aged 13-14 years from 155 centres in 56 countries. METHODS: Written symptom questionnaires were translated from English into the local language for self-completion by the 13-14-year-olds and completion by the parents of the 6-7-year-olds. Rhinitis was described as a problem with sneezing, or a runny, or blocked nose when you (your child) DID NOT have a cold or the flu. Additional questions were asked about rhinitis associated with itchy-watery eyes, interference with activities and a history of hay fever ever. RESULTS: The prevalence of rhinitis with itchy-watery eyes ("rhinoconjunctivitis") in the past year varied across centres from 0.8% to 14.9% in the 6-7-year-olds and from 1.4% to 39.7% in the 13-14-year-olds. Within each age group, the global pattern was broadly consistent across each of the symptom categories. In centres of higher prevalence there was great variability in the proportion of rhinoconjunctivitis labelled as hay fever. The lowest prevalences of rhinoconjunctivitis were found in parts of eastern Europe, south and central Asia. High prevalences were reported from centres in several regions. CONCLUSION: These results suggest substantial worldwide variations in the prevalence and labelling of symptoms of allergic rhinoconjunctivitis which require further study. These differences, if real, may offer important clues to environmental influences on allergy.

Evaluating models of working at the interface between mental health services and primary care.

BACKGROUND: This paper examines the feasibility of evaluating innovative models of working at the interface between primary care and secondary mental health services. METHOD: Methodological problems relevant to evaluation of innovative models of working at the interface are discussed. RESULTS: Although there is some evidence that neurotic disorders can be more cost-effectively treated in primary care, many general practitioners (GPs), and possibly some patients, prefer referral to community mental health teams and community psychiatric nurses, which are provided by the secondary health care services. Since the latter are provided with the intention of improving serious mental illness their involvement in the care of neurotic illness can lead to tensions between GPs, local health authorities and service providers. There is little evidence to suggest that psychiatrists working in health centres using the 'shifted out-patient' model have eased this problem. By contrast the 'consultation-liaison' (C-L) model has a number of theoretical advantages; referrals to secondary care should be limited to those most in need of this level of expertise and GP management skills should improve, so leading to better quality of care for patients who are not referred. CONCLUSION: Studies comparing the different models of service delivery are required to address the tensions that have arisen following changes in government policy. Further work is also needed to develop the necessary research tools.

Prevalence of potentially inappropriate long term prescribing in general practice in the United Kingdom, 1980-95: systematic literature review.

OBJECTIVE: To determine the prevalence of potentially inappropriate long term prescribing in general practice in the United Kingdom. DESIGN: Review of 62 studies of the appropriateness of prescribing identified from seven electronic databases, from reference lists, and by hand searching of journals. A nominal group of 10 experts helped to define the appropriateness of prescribing. SETTING: General practice in the United Kingdom. MAIN OUTCOME MEASURES: Prevalences of 19 indicators of inappropriate long term prescribing representing five dimensions: indication, choice of drug, drug administration, communication, and review. RESULTS: Prevalences of potentially inappropriate prescribing varied by indicator and chronic condition, but drug dosages outside the therapeutic range consistently recorded the highest rates. The lowest rates were generally associated with indicators of the choice of the drug, except cost minimisation. Communication is studied less frequently than other dimensions of prescribing appropriateness. CONCLUSIONS: The evidence base to support allegations of widespread inappropriate prescribing in general practice is unsound. Although inappropriate prescribing has occurred, the scale of the problem is unknown because of limitations associated with selection of a standard, publication bias, and uncertainty about the context of prescribing decisions. Opportunities for cost savings and effectiveness gains are thus unclear. Indicators applicable to individual patients could yield evidence of prescribing appropriateness.

Investigation of whether on-site general practice counsellors have an impact on psychotropic drug prescribing rates and costs.

BACKGROUND: Counselling services are now widespread within general practice. Although the cost-effectiveness of such services has yet to be fully investigated, benefits could include a reduction in prescribing of psychotropic drugs and of other drugs. AIM: A study set out to determine whether practices with counsellors differed from those without in terms of their prescribing rates and costs of psychotropic drugs. METHOD: Prescribing analyses and cost (PACT) level two data reports for the quarter to November 1991 ending January 1992, as appropriate, were sought from 354 practices with counsellors and a matched sample of 216 practices without counsellors which had participated in a previous national survey of counselling in general practice. The drug groups examined were: hypnotics and anxiolytics; antidepressants; analgesics; all central nervous system drugs; and all drugs apart from central nervous system drugs. For each group of drugs, the numbers of prescribed items, total prescribing costs, and costs per item were expressed as a proportion of the practice's number of prescribing units (that is, the age-adjusted number of registered patients) and as a percentage of the average for similar practices in its family health services authority. Practice characteristics were compared between practices with an on-site counsellor and those without. Practices with and without counsellors were compared with respect to their prescribing indicators. RESULTS: PACT reports were obtained from 214 practices (response rate 38%)--126 with counsellors and 88 without. Practices with counsellors and practices without counsellors were well matched in terms of location, list size, proportion of elderly patients, training and fundholding status, and number of health promotion clinics. No significant differences were found between practices with and without counsellors in the prescribing indicators for any group of psychotropic drugs examined or for central nervous system drugs as a whole. CONCLUSION: There were no appreciable differences found in this study between practices with and without counsellors in terms of psychotropic drug prescribing rates or costs. The reasons for this are unclear; more indepth studies of individual counselling services are required.
