How did formative research inform the development of a home-based neonatal care intervention in rural Ghana?

Formative research is often used to inform intervention design, but the design process is rarely reported. This study describes how an integrated home visit intervention for newborns in Ghana was designed. As a first step in the design process, the known intervention parameters were listed, information required to refine the intervention was then identified and a formative research strategy designed. The strategy included synthesizing available data, collecting data on newborn care practices in homes and facilities, on barriers and facilitators to adopting desired behaviors and on practical issues such as whom to include in the intervention. The data were used to develop an intervention plan through workshops with national and international stakeholders and experts. The intervention plan was operationalized by district level committees. This included developing work plans, a creative brief for the materials and completing a community volunteer inventory. The intervention was then piloted and the intervention materials were finalized. The design process took over a year and was iterative. Throughout the process, literature was reviewed to identify the best practice. The intervention focuses on birth preparedness, using treated bednets in pregnancy, early and exclusive breastfeeding, thermal care, special care for small babies and prompt care seeking for newborns with danger signs. The need for a problem-solving approach was identified to help ensure behavior change. A subset of behaviors were already being performed adequately, or were the focus of other interventions, but were important to reinforce in the visits. These include attending antenatal care and care seeking for danger signs in pregnancy. On the basis of the intervention content, the timing of newborn deaths and the acceptability of visits, two antenatal and three visits in the first week of life (days 1, 3 and 7) were planned. Several household members were identified to include in the visits as they were involved in newborn care or they made financial decisions. Birth attendants and health workers were often the locus of control for immediate newborn care, and sensitization activities were designed to improve their practices and to help ensure that families received consistent messages. An existing cadre of community volunteers was identified to deliver the intervention-these volunteers were already trusted and accepted by the community, already visited pregnant women at home and had the time and commitment to deliver the intervention. A supervision and remuneration system was developed through discussions with the volunteers and at the planning workshops. The need for community entry activities was identified to garner community support for the intervention, to encourage self-identification of pregnant and delivered women and to motivate the volunteer through community recognition. Formative research is an essential step in helping to ensure the development of an effective, appropriate and sustainable intervention.

Priority setting using multiple criteria: should a lung health programme be implemented in Nepal?

OBJECTIVES: To identify and weigh the various criteria for priority setting, and to assess whether a recently evaluated lung health programme in Nepal should be considered a priority in that country. METHODS: Through a discrete choice experiment with 66 respondents in Nepal, the relative importance of several criteria for priority setting was determined. Subsequently, a set of interventions, including the lung health programme, was rank ordered on the basis of their overall performance on those criteria. RESULTS: Priority interventions are those that target severe diseases, many beneficiaries and people of middle-age, have large individual health benefits, lead to poverty reduction and are very cost-effective. Certain interventions in tuberculosis control rank highest. The lung health programme ranks 13th out of 34 interventions. CONCLUSION: This explorative analysis suggests that the lung health programme is among the priorities in Nepal when taking into account a range of relevant criteria for priority setting. The multi-criteria approach can be an important step forward to rational priority setting in developing countries.

Psychometric properties of the Dutch version of the Hospital-level Consumer Assessment of Health Plans Survey instrument.

OBJECTIVES: To assess the reliability and validity of a translated version of the American Hospital-level Consumer Assessment of Health Plans Survey (H-CAHPS) instrument for use in Dutch health care. DATA SOURCES/STUDY SETTING: Primary survey data from adults aged 18 years or more who were recently discharged from two multispecialty city hospitals in the Netherlands. STUDY DESIGN: We used forward and backward translation procedures and a panel of experts to adapt the 66-item pilot H-CAHPS into a 70-item Dutch instrument. Descriptive statistics and standard psychometric methods were then used to test the reliability and validity of the new instrument. DATA COLLECTION: From late November 2003 to early January 2004, the survey was administered by mail to 1,996 patients discharged within the previous 2 months. PRINCIPAL FINDINGS: Analyses supported the reliability and validity of the following 7-factor H-CAHPS structure for use in Dutch hospitals: on doctor's communication, nurses' communication, discharge information, communication about medication, pain control, physical environment of hospital, and nursing services. The internal consistency reliability of the scales ranged from 0.60 to 0.88. Items related to "family receiving help when on visit,""hospital staff introducing self," and "admission delays" did not improve the psychometric properties of the new instrument. CONCLUSIONS: These findings suggest that the H-CAHPS instrument is reliable and valid for use in the Dutch context. However, more research will be needed to support its equivalence to the United States version, and its use for between-hospital comparisons.

Implementing global knowledge in local practice: a WHO lung health initiative in Nepal.

Clinical practice guidelines are used widely to improve the quality of primary health care in different health systems, including those of low-income countries. Often developed at international level and adapted to national contexts to increase the feasibility of effective uptake, guideline initiatives aim to transfer global scientific knowledge into local practice. The WHO's Practical Approach to Lung Health (PAL) is an example of such an initiative and is currently being developed to improve the quality of care for youths and adults with respiratory diseases. We assessed ex-ante the feasibility of successful implementation of PAL in a pilot programme in rural Nepal, studying three components: the quality of the innovation (i.e. the guidelines), the effectiveness of the implementation strategy (i.e. training) and the receptiveness of the social system of health staff at all levels (i.e. social and organizational characteristics). We assessed the guideline innovation with the AGREE instrument for guidelines, the intended implementation strategy by critical comparison with literature on effective strategies, and the social system with both a stakeholder analysis and a descriptive analysis of the health care system at district level. This ex-ante assessment of an adaptive local implementation of international WHO guidelines showed that in July 2002 the 'implementability' of the package was challenged on the three components studied. To increase the chances of successful implementation, the national guideline development process should be improved and the implementation strategy needs to be upgraded. In order to successfully transfer global knowledge into local practice, we need to develop additional multifactorial sustained interventions that tackle other culture-specific and health system-specific barriers as well. The primary health workers are key informants for these barriers.

Developing a national performance indicator framework for the Dutch health system.

OBJECTIVE: To report on the first phase of the development of a national performance indicator framework for the Dutch health system. METHODS: In January 2002, we initiated an informed interactive process with the intended users-policymakers at the Ministry of Health, Welfare and Sport-and academics to develop both the conceptual framework and its content. Decisions were based on consensus after discussing strategic goals of the health system, information needs of policy makers at the Ministry of Health, Welfare and Sport, and studying existing theory and international experiences with national performance indicator frameworks. We identified objectives and criteria for a framework at the national level, constructed a conceptual model, and selected indicator areas. RESULTS: As a starting point we chose a balanced scorecard reflecting four perspectives towards health system management information at the national level. These perspectives are consumer orientation, finances, delivery of high quality care, and the ability to learn and grow. We then linked the Lalonde model for population health to a balanced scorecard model. The constructed model makes the relationship between population health and health system management apparent, and facilitates the presentation of performance information from various perspectives. The model reflects the strategic goals of the Dutch health system, i.e. contributing to the production of health by providing necessary health care of good quality that is accessible for all Dutch citizens while simultaneously informing policy makers about the performance of the entire health system in all sectors (care, cure, prevention, and social services). The selected indicator areas for health system management information (20 in total) reflect the policy and management functions of the government and the defined public goals of the health system. The model was formally adopted by the Ministry of Health, Welfare and Sport in February 2003, and since then individual indicator areas have been operationalized by 30 representatives of various departments at the Ministry with continuous external research support. CONCLUSION: The merit of linking the balanced scorecard inspired model to public health data is that it facilitates the visualization of the contribution of the health system to the improvement of population health. The method of an intensive interactive indicator development process between policy makers and researchers has so far proven successful.

Conceptual frameworks for health systems performance: a quest for effectiveness, quality, and improvement.

ISSUES: Countries and international organizations have recently renewed their interest in how health systems perform. This has led to the development of performance indicators for monitoring, assessing, and managing health systems to achieve effectiveness, equity, efficiency, and quality. Although the indicators populate conceptual frameworks, it is often not very clear just what the underlying concepts might be or how effectiveness is conceptualized and measured. Furthermore, there is a gap in the knowledge of how the resultant performance data are used to stimulate improvement and to ensure health care quality. ADDRESSING THE ISSUES: This paper therefore explores, individually, the conceptual bases, effectiveness and its indicators, as well as the quality improvement dynamics of the performance frameworks of the UK, Canada, Australia, US, World Health Organization, and Organisation for Economic Co-operation and Development. RESULTS: We see that they all conceive health and health system performance in one or more supportive frameworks, but differ in concepts and operations. Effectiveness often implies, nationally, the achievement of high quality outcomes of care, or internationally, the efficient achievement of system objectives, or both. Its indicators are therefore mainly outcome and, less so, process measures. The frameworks are linked to a combination of tools and initiatives to stimulate and manage performance and quality improvement. CONCLUSIONS: These dynamics may ensure the proper environment for these conceptual frameworks where, alongside objectives such as equity and efficiency, effectiveness (therefore, quality) becomes the core of health systems performance.

Cost-effectiveness of a family and DNA based screening programme on familial hypercholesterolaemia in The Netherlands.

AIMS: To estimate the cost-effectiveness of the current screening programme on Familial Hypercholesterolaemia (FH) in relatives of diagnosed FH-patients in The Netherlands. METHODS AND RESULTS: Data from 2229 screened FH-relatives, including age, sex, risk factor status and screening outcome, were combined with the Framingham risk function and national disease-specific cost data to arrive at a model-based comparison of survival and costs, with and without the screening programme. Cost-effectiveness ratios were computed for various treatment strategies, with no screening as reference. Costs per life year gained varied between 25.5- and 32-thousand Euros, depending upon the precise treatment strategy after a positive screen. The costs for screening (tracing the FH-positive individuals) were much lower than the follow-up costs (treatment), of which 80% were costs for statins. Consequently, the costs per life year gained of alternative screening programmes are about the same. CONCLUSION: The cost-effectiveness ratio of FH screening is within the range requiring explicit political consideration in The Netherlands. As the costs of statin treatment are the single most important determinant of costs, policy decisions reduce to decisions on the acceptability of statin treatment for this risk group. Pending major changes in statin price, clear guidelines should be developed on how screen positive individuals should be treated, since not all of them have an elevated cholesterol level.

[Genetic screening for familial hypercholesterolemia in 1992-1997: primarily younger patients in the care of family physicians]. / Genetische screening op familiaire hypercholesterolemie in 1992-1997: vooral jongere patiënten onder de aandacht van de huisarts gebracht.

OBJECTIVE: To estimate the proportion of patients with familial hypercholesterolaemia (FH) who were identified with hypercholesterolaemia in general practice prior to screening by means of pedigree research and DNA analysis by the National Foundation for the Identification of Familial Hypercholesterolemia (StOEH). DESIGN: Retrospective. METHOD: General practice files of FH patients, diagnosed through genetic screening by the StOEH in 1992-1997 whose general practitioner's (GP's) practice in Amsterdam, Haarlem or Alkmaar, were studied for cholesterol and FH related information documented in the period prior to the screening. RESULTS: Out of the 121 persons selected 80 agreed to the study; one GP refused to co-operate. There was no difference between respondents and non respondents with regard to age, sex or domicile of the GP. In 48 of 79 (61%) general practice files studied, cholesterol measurements were reported prior to screening; 39 patients (49%) had hypercholesterolaemia and 29 (37%) were being treated with cholesterol lowering drugs. Mean age of the FH patients who had no record of their cholesterol levels was 25.1 years (SD: 17.0) at the time of screening, 22 years younger than the mean age of FH patients who did have cholesterol levels on record prior to screening (47.1 (SD: 18.4); p < 0.0001). CONCLUSION: Of the FH patients identified through family based genetic screening especially the younger FH patients are newly brought to the attention of their GP.

Estimation of serial interval and incubation period of tuberculosis using DNA fingerprinting.

OBJECTIVE: To determine the frequency distributions of serial interval and incubation period of tuberculosis within 4 years of transmission, and to identify correlates of serial intervals and incubation periods. METHODS: DNA fingerprints were obtained for all isolates from all culture-positive patients notified in The Netherlands from 1993 to 1996. Patient information was obtained from the National Tuberculosis Register. Results from contact investigations were provided by public health services. Source cases and secondary cases of tuberculosis were identified, based on 1) identical DNA fingerprints, and 2) epidemiological confirmation of contact. Under-representation of long intervals were corrected for by weighting cases. RESULTS: A total of 69 source-secondary case couples were identified. The geometric mean serial interval was 29.5 weeks (95% confidence interval [CI] 22.8-38.2 weeks) and the geometric mean incubation period 20.8 weeks (95% CI 15.5-27.8 weeks). Serial intervals and incubation periods tended to increase with age (P > 0.05). Three secondary cases with human immunodeficiency virus infection showed very short incubation periods (P > 0.05). CONCLUSION: Using a new methodology, the distribution of incubation periods of tuberculosis gave results consistent with earlier studies.
