Issues in bioethics: ethics in health policy and guidelines in healthcare

The development of policies in health and healthcare should incorporate ethical premises as well as thoughtful consideration of the values pertinent to the particular society and the goals to be achieved by specific policies. Social inequalities, changing values, and emergent challenges to traditional beliefs, add complexities that require a thorough analysis to compile policies that are fair and equitable. This article provides some recommendations for clinicians, health administrators, policy makers and technocrats who often grapple with complex health issues.

NIKE: a new clinical tool for establishing levels of indications for cataract surgery

PURPOSE

The purpose of this study was to construct a new clinical tool for establishing levels of indications for cataract surgery, and to validate this tool.

METHODS

Teams from nine eye clinics reached an agreement about the need to develop a clinical tool for setting levels of indications for cataract surgery and about the items that should be included in the tool. The tool was to be called 'NIKE' (Nationell Indikationsmodell för Kataraktextraktion). The Canadian Cataract Priority Criteria Tool served as a model for the NIKE tool, which was modified for Swedish conditions. Items included in the tool were visual acuity of both eyes, patients' perceived difficulties in day-to-day life, cataract symptoms, the ability to live independently, and medical/ophthalmic reasons for surgery. The tool was validated and tested in 343 cataract surgery patients. Validity, stability and reliability were tested and the outcome of surgery was studied in relation to the indication setting.

RESULTS

Four indication groups (IGs) were suggested. The group with the greatest indications for surgery was named group 1 and that with the lowest, group 4. Validity was proved to be good. Surgery had the greatest impact on the group with the highest indications for surgery. Test-retest reliability test and interexaminer tests of indication settings showed statistically significant intraclass correlations (intraclass correlation coefficients [ICCs] 0.526 and 0.923, respectively).

CONCLUSIONS

A new clinical tool for indication setting in cataract surgery is presented. This tool, the NIKE, takes into account both visual acuity and the patient's perceived problems in day-to-day life because of cataract. The tool seems to be stable and reliable and neutral towards different examiners.

Towards a multi-criteria approach for priority setting: an application to Ghana

BACKGROUND

Many criteria have been proposed to guide priority setting in health, but their relative importance has not yet been determined in a way that allows a rank ordering of interventions.

METHODS

In an explorative study, a discrete choice experiment was carried out to determine the relative importance of different criteria in identifying priority interventions in Ghana. Thirty respondents chose between 12 pairs of scenarios that described interventions in terms of medical and non-medical criteria. Subsequently, a composite league table was constructed to rank order a set of interventions by mapping interventions on those criteria and considering the relative weights of different criteria.

RESULTS

Interventions that are cost-effective, reduce poverty, target severe diseases, or target the young had a higher probability of being chosen than others. The composite league table showed that high priority interventions in Ghana are prevention of mother to child transmission in HIV/AIDS control, and treatment of pneumonia and diarrhoea in childhood. Low priority interventions are certain interventions to control blood pressure, tobacco and alcohol abuse. The composite league table lead to a different and more differentiated rank ordering of interventions compared to pure efficiency ratings.

CONCLUSION

This explorative study has introduced a multi-criteria approach to priority setting. It has shown the feasibility of accounting for efficiency, equity and other societal concerns in prioritization decisions, and its potentially large impact on priority setting.

Prioridades de saúde no Brasil nos anos 1990: três políticas, muitas lições

This paper, which focuses on the Brazilian Ministry of Health's agenda as the national health authority between 1990 and 2002, identifies and analyzes Ministry priorities. Three main policies were identified for the period: decentralization, establishment of a family health program, and the policy to combat AIDS. In general, the initial design of these policies was consistent with the guidelines of the Brazilian public health system (SUS). However, discrepancies were found between the universalistic agenda of the Brazilian health reform carried out in the 1980s and the hegemonic agenda of state reform that prevailed in the country in the 1990s, which had liberal roots and did not favor the expansion of government actions and comprehensive social policies. Within this unfavorable political and economic context, the development of specific health policies prioritized by the Brazilian Ministry of Health revealed unsolved problems and gaps in the public health system and limitations in the Ministry's ability to exercise its role as national health authority.

Malaria, anemia, and malnutrition in african children--defining intervention priorities

BACKGROUND

Malaria, anemia, and malnutrition contribute substantially to childhood morbidity in sub-Saharan Africa, but their respective roles and interactions in conferring disease are complex. We aimed to investigate these interactions.

METHODS

In 2002, we assessed plasmodial infection, anemia, and nutritional indices in 2 representative surveys comprising >4000 children in northern Ghana.

RESULTS

Infection with Plasmodium species was observed in 82% and 75% of children in the rainy and dry season, respectively. The fraction of fever attributable to malaria was 77% in the rainy season and 48% in the dry season and peaked in children of rural residence. Anemia (hemoglobin level, <11 g/dL) was seen in 64% of children and was, in multivariate analysis, associated with young age, season, residence, parasitemia, P. malariae coinfection, and malnutrition (odds ratio [OR], 1.68 [95% confidence interval [CI], 1.38-2.04]). In addition, malnutrition was independently associated with fever (axillary temperature, > or = 37.5 degrees C; OR, 1.59 [95% CI, 1.13-2.23]) and clinical malaria (OR, 1.67 [95% CI, 1.10-2.50]).

CONCLUSIONS

Malnutrition is a fundamental factor contributing to malaria-associated morbidity and anemia, even if the latter exhibits multifactorial patterns. Our data demonstrate that malaria-control programs alone may not have the desired impact on childhood morbidity on a large scale without concomitant nutrition programs.

Prioritizing IVF patients according to the number of existing children—a proposed refinement to the current guideline

The National Health Service is poised to offer at least one cycle of IVF treatment to couples free of charge in the UK, provided that certain clinical criteria are met. At a local level, therefore, funders are faced with the problem of prioritizing patients and establishing waiting lists. It is generally accepted that preference should be given to those with the 'greatest need', but it is uncertain what the criterion is for greatest need. We propose two recommendations as a modification to the current guideline that stresses the need to favour 'couples who do not have any children living with them'. First, we suggest that parental responsibility rather than shared residence be used as a criterion for eligibility. Second, we present a need-based approach that can be used coherently to distribute publicly funded treatment. In an attempt to achieve a fair way of prioritizing patients, we make distinctions between different family arrangements, based on the number of existing children. Our approach treats like cases alike, and ranks different cases relative to each other in a manner that is equitable and charitable.

Health care need: three interpretations

The argument that scarce health care resources should be distributed so that patients in 'need' are given priority for treatment is rarely contested. In this paper, we argue that if need is to play a significant role in distributive decisions it is crucial that what is meant by need can be precisely articulated. Following a discussion of the general features of health care need, we propose three principal interpretations of need, each of which focuses on separate intuitions. Although this account may not be a completely exhaustive reflection of what people mean when they refer to need, the three interpretations provide a starting-point for further debate of what the concept means in its specific application. We discuss combined interpretations, the meaning of grading needs, and compare needs-based priority setting to social welfare maximisation.

Patient and physician perspectives of maximum acceptable waiting times for cataract surgery

BACKGROUND

Lengthy waiting times for cataract surgery are an important issue in countries with publicly funded health care systems. To improve the fairness, timeliness, and certainty of waiting-time management, the Western Canada Waiting List Project has developed priority criteria scores (PCSs) related to urgency and linked to maximum acceptable waiting times (MAWTs). The purpose of our study was to compare patient and physician perspectives of MAWT for different levels of urgency. A second aim was to assess the determinants of patient and surgeon perspectives on MAWT.

METHODS

Ophthalmologists assessed consecutive patients waitlisted for cataract surgery. Data included a MAWT, a visual analogue scale of urgency (VAS urgency), and the cataract PCS. Patients were mailed questionnaires to assess their perspectives of MAWT and VAS urgency. They were also sent a measure of visual function called the Visual Function Assessment. We used hierarchical linear regression to assess the determinants of MAWT.

RESULTS

The mean age of the 213 patients was 73.9 years; 56.8% were female and 71.8% were booked for first eye surgery. Physician-rated MAWT was significantly longer than patient-rated MAWT (mean 15.1 vs. 9.9 weeks). Median physician MAWTs ranged from 12 (most urgent) to 20 (least urgent) weeks, and patient MAWTs, from 4 to 8 weeks. A 3-step hierarchical linear regression model showed that, after adjusting for age and sex, the priority criteria added significantly to the surgeon model (R2 change = 0.22). Significant predictors were ocular comorbidity, impairment in visual function, and ability to work or live independently or care for dependents. After the addition of VAS urgency, the final model explained 42% of the variance in surgeon MAWT. Significant predictors were age-related macular degeneration and VAS urgency. A 4-step hierarchical regression model for patient MAWT showed that after step 2, sex and visual acuity in the nonsurgery eye were significant predictors. The final model accounted for 11% of the variance in patient MAWT. Significant predictors were sex (males had lower MAWT) and VAS urgency.

INTERPRETATION

Patient and physician views on MAWT differ, yet both are critical to a fair process for developing standardized waiting times related to levels of urgency. Results from this study provide initial inputs to the formulation of benchmark waiting times for different levels of the cataract PCS.

Older people's views of prioritization in health care. The applicability of an interview study

AIM

Older people's views of prioritization in health care. The applicability of an interview study. Old age has been stated as a criterion for prioritization in health care, although older people are seldom asked for their opinions. The aim of this pilot study was to investigate the applicability of a questionnaire as a base for an interview study to explore older people's experiences and views of prioritization in health care.

DESIGN

Descriptive, with a qualitative and quantitative approach. Fifty-four persons, 32 women and 22 men (aged 60-93 years), were asked to participate in a structured, tape-recorded interview covering their experience and views of the priorities applied in health care.

RESULTS

The questions in the interview manual appeared to be applicable for collecting data concerning views of prioritization, but the analysis revealed that certain questions, particularly on economic matters, were missing. The procedure, a personal structured interview had advantages, for example, in capturing the respondents' reflections on the questions. The respondents emphasized the equal value of all human beings and that age is not a basis for prioritization within health care. The respondents also showed an unwillingness to precede anyone in rank.

IMPLICATIONS

The questions used proved to be adequate but to be really complete further questions need to be added. This pilot study indicates that older people's views on priorities in health care differ from those expressed by the younger population. The study therefore needs to be replicated in a larger sample to be fully able to understand older people's views of prioritization, which will require exploring gender and age differences as well as other aspects that may explain variations.

The prioritization of patients on waiting lists for cataract surgery: validation of the Western Canada waiting list project cataract priority criteria tool

PURPOSE

To assess the validity of the Cataract Priority Criteria Score (PCS), developed by the Western Canada Waiting List (WCWL) Project to determine patient prioritization for cataract surgery.

METHODS

Ophthalmologists assessed consecutive patients with the PCS and a visual analogue scale of urgency (VAS Urgency). Patients were mailed questionnaires pre- and post-surgery. Outcome measures were the Visual Function Assessment (VFA), EuroQol (EQ-5D), and best-corrected visual acuity.

RESULTS

The sample of 253 patients was 58% female (mean age, 73.7 years); 166 completed pre-and post-surgery VFA. The correlation of the PCS and VAS Urgency was 0.65 (p = 0.000). Adjusting for age, first or second eye surgery, and post-operative complication, the PCS predicted improvement in the VFA and visual acuity (p < .05).

CONCLUSIONS

These data provide some evidence to support the convergent and predictive validity of the PCS. Multiple patient outcomes should be used in the evaluation of the validity of priority scores.

Malaria and urbanization in sub-Saharan Africa

There are already 40 cities in Africa with over 1 million inhabitants and the United Nations Environmental Programme estimates that by 2025 over 800 million people will live in urban areas. Recognizing that malaria control can improve the health of the vulnerable and remove a major obstacle to their economic development, the Malaria Knowledge Programme of the Liverpool School of Tropical Medicine and the Systemwide Initiative on Malaria and Agriculture convened a multi-sectoral technical consultation on urban malaria in Pretoria, South Africa from 2nd to 4th December, 2004. The aim of the meeting was to identify strategies for the assessment and control of urban malaria. This commentary reflects the discussions held during the meeting and aims to inform researchers and policy makers of the potential for containing and reversing the emerging problem of urban malaria.

Are QALYs based on time trade-off comparable?--A systematic review of TTO methodologies

A wide range of methods is used to elicit quality-of-life weights of different health states to generate 'Quality-adjusted life years' (QALYs). The comparability between different types of health outcomes at a numerical level is the main advantage of using a 'common currency for health' such as the QALY. It has been warned that results of different methods and perspectives should not be directly compared in QALY league tables. But do we know that QALYs are comparable if they are based on the same method and perspective?The Time trade-off (TTO) consists in a hypothetical trade-off between living shorter and living healthier. We performed a literature review of the TTO methodology used to elicit quality-of-life weights for own, current health. Fifty-six journal articles, with quality-of-life weights assigned to 102 diagnostic groups were included. We found extensive differences in how the TTO question was asked. The time frame varied from 1 month to 30 years, and was not reported for one-fourth of the weights. The samples in which the quality-of-life weights were elicited were generally small with a median size of 53 respondents. Comprehensive inclusion criteria were given for half the diagnostic groups. Co-morbidity was described in less than one-tenth of the groups of respondents. For two-thirds of the quality-of-life weights, there was no discussion of the influence of other factors, such as age, sex, employment and children. The different methodological approaches did not influence the TTO weights in a predictable or clear pattern. Whether or not it is possible to standardise the TTO method and the sampling procedure, and whether or not the TTO will then give valid quality-of-life weights, remains an open question.This review of the TTO elicited on own behalf, shows that limiting cost-utility analysis to include only quality life weights from one method and one perspective is not enough to ensure that QALYs are comparable.

Violence against women: outcome complexity and implications for assessment and treatment

This article reviews the major forms of violence against women, including sexual assault, intimate-relationship violence, and stalking and outlines the known psychological effects of such victimization. Also discussed are a number of variables that combine to determine the effects of such victimization, including type and characteristics of the assault; victim variables such as demographics, psychological reactions at the time of the trauma, previous victimization history, current or previous psychological difficulties, and general coping style; and sociocultural factors such as poverty, social inequality, and inadequate social support. The implications of this complexity are explored in terms of psychological assessment and the frequent need for multitarget, multimodal treatment approaches.

What is violence against women: defining and measuring the problem

Violence against women (VAW) is a prevalent problem with substantial physical and mental health consequences throughout the world, and sound public policy is dependent on having good measures of VAW. This article (a) describes and contrasts criminal justice and public health approaches toward defining VAW, (b) identifies major controversies concerning measurement of VAW, (c) summarizes basic principles in identifying and measuring VAW cases, and (d) recommends changes to improve measurement of VAW. In addition to reviewing recommendations from the Centers for Disease Control and Prevention Workshop on Building Data Systems for Monitoring and Responding to Violence Against Women and the World Health Organization World Report on Violence and Health, the article concludes that changes are needed in the FBI Uniform Crime Reports and National Crime Victimization Survey to improve measurement of rape and sexual assault.

Issues related to defining and measuring violence against women: response to Kilpatrick

This paper asserts that although there is considerable agreement in the U.S. and internationally about the importance of uniform terminology and measurement related to violence against women, we need a strategy for choosing standardized definitions and measures. Responding to Kilpatrick's comments at the October 2003 national research conference on violence against women, the author stresses the importance of developing and using uniform terminology related to violence against women, and discusses the lack of a formal mechanism to achieve uniformity of definitions and measurement. Uncertainty about the impact of context on survey findings and the lack of agreement about the optimal scope of measurement are discussed. The author also comments on some difficulties associated with implementing Kilpatrick's proposed modifications to existing measures of rape and sexual assault.

Identifying priority actions for improving patient satisfaction with outpatient cancer care

In parallel to developing new cancer therapies, the healthcare community has the responsibility of creating positive treatment experiences for patients. Data from 5907 cancer outpatients treated at 23 hospitals across the United States were analyzed to identify the top priorities for service improvement in outpatient cancer treatment facilities. They included meeting patients' emotional needs, providing information to patients and family members, reducing waiting times, and providing convenience and coordinated care among physicians and other care providers.

Development and assessment of a priority score for cataract surgery

BACKGROUND

Point-count measures of clinical priority are increasingly put forward for managing waiting lists. However, their development does not consider explicitly the appropriateness of the indications. Furthermore, an estimate of their effect in clinical practice is needed, assessing the amount of gains and losses in terms of time waited for patients with different priority scores.

METHODS

We developed appropriateness criteria for cataract surgery using the RAND method and applied them to a sample of 567 patients consecutively placed on a waiting list for cataract surgery. In addition, clinicians were asked to express the priority attributed to each patient using a 10-cm visual analogue scale, where 0 = minimal priority and 10 = maximum priority. We developed a priority score, using regression analysis to identify the set of clinical characteristics that best predicted clinicians' priority rating and to estimate their individual weight. We used a computer simulation model to compare mean waiting times with management of the waiting list using the priority score and using the "first-come, first-served" approach.

RESULTS

Overall, 332 patients (60.8%) were referred for cataract surgery for indications deemed appropriate, and their mean priority rating was 5.9 (95% confidence interval [CI] 5.7-6.1). The corresponding figures for the 201 (36.8%) uncertain indications and the 13 (2.4%) inappropriate indications were 4.5 (95% CI 4.1-4.7) and 2.6 (95% CI 1.3-3.9) respectively. The clinical characteristics included in the priority score (visual acuity in the operated eye and in the contralateral eye, visual function and ability to live or work independently) accounted for 35% of the variance in clinicians' ratings of priority. In the computer simulation model, patients with the highest priority experienced a variable reduction in mean waiting time (9% to 27%) depending to how time spent waiting was integrated into the clinical score.

INTERPRETATION

We conclude that the use of priority ratings in the management of a waiting list for cataract surgery leads to results that maintain the desirable coherence between priority and appropriateness of indication. The results also suggest that the implementation in clinical practice of priority scores may be worth the effort, given the potential reduction in waiting time for patients at high priority.

Strategic emphases for tropical diseases research: a TDR perspective

Setting priorities for health research is a difficult task, especially for the neglected diseases of the poor. A new approach to priority setting for tropical diseases research has been adopted by the UNDP/World Bank/WHO Special Programme for Research and Training in Tropical Diseases (known as the TDR). Priorities are defined on the basis of a comprehensive analysis of research needs and research opportunities for each of the ten major tropical diseases in the TDR portfolio. The resulting strategic emphases matrix reflects the priorities for tropical diseases research from the perspective of the TDR. Its purpose is not to impose global research priorities, but we believe the results could be useful to other organizations.
