The use of Method Information Index (MII) to monitor the amount of information given to women users of modern contraceptives in Indonesia: results from an analysis of the 2007, 2012 and 2017 demographic and health surveys

BACKGROUND

The use of Method Information Index (MII) indicates whether women contraceptive users receive adequate information about all available contraceptive methods, side effects of the methods, and how to deal with the side effects if experienced-at method initiation.

OBJECTIVE

This study aims to investigate the level of MII scores or the amount of information received by married women users of five modern contraceptives at the time of initiation and changes of its determinants based on the Indonesian Demographic and Health data between 2007 and 2017.

METHODS

Data of married women who used most common five modern contraceptive methods (the pill, injectables, implants, IUD, and female sterilization), comprised of a total unweighted sample of 35,412 users out of the 32,895; 45,607 and 49,627 women aged 15-49 in the 2007, 2012, and 2017 Indonesian Demographic and Health Survey (IDHS), respectively. The Method Information Index (MII) scores were calculated based on responses to three questions (whether women were told about method-specific side effects, advised what to do if they experienced them, and informed about other available methods). Multivariable logistic regressions with 'time' as an interaction variable were used to assess the influence of time upon the MII scores and its determinants.

RESULTS

The MII scores were 23.84% in 2007, 24.60% in 2012 and 28.65% in 2017. Obviously, over 70% of reproductive-age women contraceptive users were not receiving complete information about modern contraceptives at the time of initiation. After 5 years (2012), only living in the Java Bali region (AOR = 1.34, 95% CI 1.09-1.66) compared to living in other islands, and currently using injectables (AOR = 1.43, 95% CI 1.10-1.87) and currently using implants (AOR = 1.68, 95% CI 1.07-2.63) compared to currently using pills had significantly higher odds of receiving MII information. After 10 years (2017), only one variable (the 'richest' in the wealth quintile category (AOR = 0.70, 95% CI 0.50-0.99) compared to the 'poorest') still showed a significant association with receipt of complete MII information.

CONCLUSIONS

Despite the fact that the MII scores increased gradually across the years, interaction with 'survey time' showed that the likelihood of receiving complete MII information was not statistically different in the 5 years (2007-2012) and in the 10 years (2007-2017) period from the reference category in 2007. The authors recommend use of the MII score as an objective measure to evaluate access to MII essential information and to monitor an increase in the informed population in Indonesia.

Would the Public Support a Ban on Smoking in Public Places? - A Survey of Local Opinion in the North East of England

The purpose of study is to determine the degree of support for a general ban on smoking in public places and bans on smoking in specific locations amongst adults living in the North East of England. To assess the variation in support for smoking bans by smoking status and socio-demographic factors. Procedures: After appropriate training, ten medical students conducted interviews with members of the public in city centre locations. Interviewers adhered to a structured schedule and all participants gave informed consent. Quota sampling techniques were used to obtain a sample representative of the wider population in terms of age, gender and occupational social class. Main findings: Interviews were conducted with 538 individuals of whom 338 (63%) stated that they would support a general ban on smoking in public places. Support for a ban varied by smoking status and social class but not by gender or age group. Of the specific locations mentioned, support was greatest for smoking bans in restaurants and cafes (83%), shopping malls (72%) and workplaces (72%) and lowest for smoking bans in pubs and clubs (37%), the home (27%) and outdoor public places (23%). Conclusions: Local support for bans on smoking in public places in the North East of England is high - particularly in relation to bans in restaurants and cafes, shopping malls and workplaces. Introduction and enforcement of smoking bans in these locations would not be expected to meet with great opposition and may have a positive influence on public health.

"Academic racism" and the neglected scholarship of the anatomist M. Wharton Young, MD, PhD (1904-1986)

Moses Wharton Young, MD, PhD (1904-1986), was an African American Professor of Neuroanatomy at Howard University College of Medicine from 1934 to 1973, during which time he authored about 100 publications on topics that included baldness, asthma, glaucoma, and, most importantly, the structure and function of the inner ear and the pathophysiology of blast injuries. Much of Young's research was ignored during his lifetime, raising the question whether this professional neglect was an instance of "academic racism."

Development of Sensory Structures in Organ Cultures of the Twelfth and Thirteenth Gestation Day Mouse Embryo Inner Ears

Twelfth and thirteenth gestation day mouse embryo otocysts have been explanted into an organ culture system that promotes advances in morphogenesis and differentiation of sensory structures. The pattern of morphogenesis that occurs “in vitro” is not equivalent to that which occurs in the “in vivo” environment. These morphogenetic changes occur with greatest frequency in the explanted thirteenth gestation day otocyst. The development of sensory structures occurs with equal distribution in the twelfth and thirteenth gestation day explanted otocysts. The thirteenth gestation day mouse otocyst favors the development of organ of Corti type formations, and the twelfth gestation day otocyst favors the development of maculae of sensory cells of a vestibular character in the organ culture system employed. The thirteenth gestation day otocyst requires a shorter period of “in vitro” development to produce differentiation of sensory structures. The sensory structures that develop “in vitro” follow the pattern of the sensory structures that develop “in vivo.”

The quagga and science: what does the future hold for this extinct zebra?

Quaggas, partially striped zebras from South Africa, have had major impacts on science. In the 19th century, the results of mating between a quagga stallion and a horse mare influenced thinking about mechanisms of inheritance for more than 70 years. In the 20th century, tissue from a quagga yielded the first DNA of an extinct organism to be cloned and sequenced. Selective breeding of plains zebras in South Africa has produced animals whose coat coloration resembles that of some quaggas. This raises the intriguing possibility that quaggas may once again be the focus of scientific investigations.

Recent changes in human resources for health and health facilities at the district level in Indonesia: evidence from 3 districts in Java

BACKGROUND

There is continuing discussion in Indonesia about the need for improved information on human resources for health at the district level where programs are actually delivered. This is particularly the case after a central government decision to offer doctors, nurses and midwives on contract the chance to convert to permanent civil service status. Our objective here is to report changes between 2006 and 2008 in numbers and employment status of health staff in three districts following the central government decision.

METHODS

Information was derived from records at the district health office and, where necessary for clarification, discussions with district officials.

RESULTS

Across the three districts and all public sector provider categories there was an increase of almost 680 providers between 2006 and 2008 - more than 300 nurses, more than 300 midwives and 25 doctors. The increases for permanent public servants were proportionately much greater (43%) than the total (16%). The increase in those who are permanent civil servants was greatest for nurses (51%) and midwives (35%) with corresponding decreases in the proportion of staff on contract. There was considerable variation between the three districts.

CONCLUSIONS

There has been a significant increase in the number of healthcare providers in the 3 districts surveyed and the proportion now permanent public servants has increased even more than the increase in total numbers. The changes have the effect of increasing the proportion of total public expenditure allocated to salaries and reducing the flexibility of the districts in managing their own budgets. Because public servants are allowed private practice outside office hours there has also been an increase in the number of private practice facilities offering health care. These changes illustrate the need for a much improved human resources information system and a coherent policy to guide actions on human resources for health at the national, provincial and district levels.

Current situation of midwives in indonesia: Evidence from 3 districts in West Java Province

Background

The village midwife is a central element of Indonesia's strategy to improve maternal and child health and family planning services. Recently there has been concern that the midwives were not present in the villages to which they had been assigned. To determine the extent to which this was the case we conducted a field-based census and survey of village midwives in three districts in West Java Province, Indonesia.

Findings

In June 2009 we interviewed a random sample of village midwives from three districts - Ciamis, Garut and Sukabumi - in West Java Province. Trained interviewers visited all villages represented in the sample to interview the midwives. We also obtained information about the midwives and their professional activities in the last year.

Thirty percent of village midwives had moved to another location in the 12 months between the end of 2008, when the sampling frame was constructed, and December 2009 when the survey was conducted; most had moved to a government health center or another village. Of those who were present, there was considerable variation between districts in age distribution and qualifications. The total number of services provided was modest, also with considerable variation between districts. The median number of deliveries assisted in the last year was 64; the amount and mix of family planning services provided varied between districts and were dominated by temporary methods.

Conclusions

Compared to an earlier survey in an adjacent province, the village midwives in these three districts were younger, had spent less time in the village and a higher proportion were permanent civil servants. A high proportion had moved in the previous year with most moving to a health center or another village. The decision to move, as well as the mix of services offered, seems to be largely driven by opportunities to increase their private practice income. These opportunities are greater in urban areas. As urbanization procedes the forces drawing village midwives away from the village are certain to strengthen. This will require a reassessment of the original service model embodied in the village midwife concept and a new approach to reducing maternal mortality.

Why don't some women attend antenatal and postnatal care services?: a qualitative study of community members' perspectives in Garut, Sukabumi and Ciamis districts of West Java Province, Indonesia

Background

Antenatal, delivery and postnatal care services are amongst the recommended interventions aimed at preventing maternal and newborn deaths worldwide. West Java is one of the provinces of Java Island in Indonesia with a high proportion of home deliveries, a low attendance of four antenatal services and a low postnatal care uptake. This paper aims to explore community members' perspectives on antenatal and postnatal care services, including reasons for using or not using these services, the services received during antenatal and postnatal care, and cultural practices during antenatal and postnatal periods in Garut, Sukabumi and Ciamis districts of West Java province.

Methods

A qualitative study was conducted from March to July 2009 in six villages in three districts of West Java province. Twenty focus group discussions (FGDs) and 165 in-depth interviews were carried out involving a total of 295 respondents. The guidelines for FGDs and in-depth interviews included the topics of community experiences with antenatal and postnatal care services, reasons for not attending the services, and cultural practices during antenatal and postnatal periods.

Results

Our study found that the main reason women attended antenatal and postnatal care services was to ensure the safe health of both mother and infant. Financial difficulty emerged as the major issue among women who did not fulfil the minimum requirements of four antenatal care services or two postnatal care services within the first month after delivery. This was related to the cost of health services, transportation costs, or both. In remote areas, the limited availability of health services was also a problem, especially if the village midwife frequently travelled out of the village. The distances from health facilities, in addition to poor road conditions were major concerns, particularly for those living in remote areas. Lack of community awareness about the importance of these services was also found, as some community members perceived health services to be necessary only if obstetric complications occurred. The services of traditional birth attendants for antenatal, delivery, and postnatal care were widely used, and their roles in maternal and child care were considered vital by some community members.

Conclusions

It is important that public health strategies take into account the availability, affordability and accessibility of health services. Poverty alleviation strategies will help financially deprived communities to use antenatal and postnatal health services. This study also demonstrated the importance of health promotion programs for increasing community awareness about the necessity of antenatal and postnatal services.

Why do some women still prefer traditional birth attendants and home delivery?: a qualitative study on delivery care services in West Java Province, Indonesia

BACKGROUND

Trained birth attendants at delivery are important for preventing both maternal and newborn deaths. West Java is one of the provinces on Java Island, Indonesia, where many women still deliver at home and without the assistance of trained birth attendants. This study aims to explore the perspectives of community members and health workers about the use of delivery care services in six villages of West Java Province.

METHODS

A qualitative study using focus group discussions (FGDs) and in-depth interviews was conducted in six villages of three districts in West Java Province from March to July 2009. Twenty FGDs and 165 in-depth interviews were conducted involving a total of 295 participants representing mothers, fathers, health care providers, traditional birth attendants and community leaders. The FGD and in-depth interview guidelines included reasons for using a trained or a traditional birth attendant and reasons for having a home or an institutional delivery.

RESULTS

The use of traditional birth attendants and home delivery were preferable for some community members despite the availability of the village midwife in the village. Physical distance and financial limitations were two major constraints that prevented community members from accessing and using trained attendants and institutional deliveries. A number of respondents reported that trained delivery attendants or an institutional delivery were only aimed at women who experienced obstetric complications. The limited availability of health care providers was reported by residents in remote areas. In these settings the village midwife, who was sometimes the only health care provider, frequently travelled out of the village. The community perceived the role of both village midwives and traditional birth attendants as essential for providing maternal and health care services.

CONCLUSIONS

A comprehensive strategy to increase the availability, accessibility, and affordability of delivery care services should be considered in these West Java areas. Health education strategies are required to increase community awareness about the importance of health services along with the existing financing mechanisms for the poor communities. Public health strategies involving traditional birth attendants will be beneficial particularly in remote areas where their services are highly utilized.

Health system performance at the district level in Indonesia after decentralization

Background

Assessments over the last two decades have showed an overall low level of performance of the health system in Indonesia with wide variation between districts. The reasons advanced for these low levels of performance include the low level of public funding for health and the lack of discretion for health system managers at the district level. When, in 2001, Indonesia implemented a radical decentralization and significantly increased the central transfer of funds to district governments it was widely expected that the performance of the health system would improve. This paper assesses the extent to which the performance of the health system has improved since decentralization.

Methods

We measured a set of indicators relevant to assessing changes in performance of the health system between two surveys in three areas: utilization of maternal antenatal and delivery care; immunization coverage; and contraceptive source and use. We also measured respondents' demographic characteristics and their living circumstances. These measurements were made in population-based surveys in 10 districts in 2002-03 and repeated in 2007 in the same 10 districts using the same instruments and sampling methods.

Results

The dominant providers of maternal and child health in these 10 districts are in the private sector. There was a significant decrease in birth deliveries at home, and a corresponding increase in deliveries in health facilities in 5 of the 10 districts, largely due to increased use of private facilities with little change in the already low use of public facilities. Overall, there was no improvement in vaccination of mothers and their children. Of those using modern contraceptive methods, the majority obtained them from the private sector in all districts.

Conclusions

There has been little improvement in the performance of the health system since decentralization occurred in 2001 even though there have also been significant increases in public funding for health. In fact, the decentralization has been limited in extent and structural problems make management of the system as a whole difficult. At the national level there has been no real attempt to envision the health system that Indonesia will need for the next 20 to 30 years or how the substantial public subsidy to this lightly regulated private system could be used in creative ways to stimulate innovation, mitigate market failures, improve equity and quality, and to enhance the performance of the system as a whole.

Health facilities at the district level in Indonesia

Background

At Independence the Government of Indonesia inherited a weak and unevenly distributed health system to which much of the population had only limited access. In response, the government decided to increase the number of facilities and to locate them closer to the people. To staff these health facilities the government introduced obligatory government service for all new graduates in medicine, nursing and midwifery. Most of these staff also established private practices in the areas in which they were located. The health information system contains little information on the health care facilities established for private practice by these staff. This article reports on the results of enumerating all health facilities in 15 districts in Java.

Methods

We enumerated all healthcare facilities, public and private, by type in each of 15 districts in Java.

Results

The enumeration showed a much higher number of healthcare facilities in each district than is shown in most reports and in the health information system which concentrates on public, multi-provider facilities. Across the 15 districts: 86% of facilities were solo-provider facilities for outpatient services; 13% were multi-provider facilities for outpatient services; and 1% were multi-provider facilities offering both outpatient and inpatient services.

Conclusion

The relatively good distribution of health facilities in Indonesia was achieved through establishing public health centers at the sub-district level and staffing them through a system of compulsory service for doctors, nurses and midwives. Subsequently, these public sector staff also established solo-provider facilities for their own private practice; these solo-provider facilities, of which those for nurses are almost half, comprise the largest category of outpatient care facilities, most are not included in official statistics. Now that Indonesia no longer has mandatory service for newly graduated doctors, nurses and midwives, it will have difficulty maintaining the distribution of facilities and providers established through the 1980s. The current challenge is to envision a new health system that responds to the changing disease patterns as well as the changes in distribution of health facilities.

Public funding of health at the district level in Indonesia after decentralization-sources, flows and contradictions

BACKGROUND

During the Suharto era public funding of health in Indonesia was low and the health services were tightly controlled by the central government; district health staff had practically no discretion over expenditure. Following the downfall of President Suharto there was a radical political, administrative and fiscal decentralization with delivery of services becoming the responsibility of district governments. In addition, public funding for health services more than doubled between 2001 and 2006. It was widely expected that services would improve as district governments now had both more adequate funds and the responsibility for services. To date there has been little improvement in services. Understanding why services have not improved requires careful study of what is happening at the district level.

METHODS

We collected information on public expenditure on health services for the fiscal year 2006 in 15 districts in Java, Indonesia from the district health offices and district hospitals. Data obtained in the districts were collected by three teams, one for each province. Information on district government revenues were obtained from district public expenditure databases maintained by the World Bank using data from the Ministry of Finance.

RESULTS

The public expenditure information collected in 15 districts as part of this study indicates district governments are reliant on the central government for as much as 90% of their revenue; that approximately half public expenditure on health is at the district level; that at least 40% of district level public expenditure on health is for personnel, almost all of them permanent civil servants; and that districts may have discretion over less than one-third of district public expenditure on health; the extent of discretion over spending is much higher in district hospitals than in the district health office and health centers. There is considerable variation between districts.

CONCLUSION

In contrast to the promise of decentralization there has been little increase in the potential for discretion at the district level in managing public funds for health - this is likely to be an important reason for the lack of improvement in publicly funded health services. Key decisions about money are still made by the central government, and no one is held accountable for the performance of the sector - the district blames the center and the central ministries (and their ministers) are not accountable to district populations.

Antiretroviral therapy and HIV prevention in India: modeling costs and consequences of policy options

OBJECTIVES

The objective of this study is to assess the costs, cost-effectiveness, and HIV epidemic impact of 3 antiretroviral therapy (ART) policy options.

STUDY DESIGN

We constructed an epidemiologic model to predict the course of the HIV epidemic in the absence of expanded ART availability. Based on background studies of the willingness to pay for ART among patients with AIDS, of the costs to the government of the alternative treatment interventions, and of ART's likely effects on HIV transmission, we simulated the consequences of 3 possible alternative government ART policies.

RESULTS

A program to reduce the negative consequences of the currently unstructured private-sector provision of ART is the most cost-effective of the 3 options at a 10% discount rate and least cost-effective at a 3% rate. The costs and cost-effectiveness of all options are highly sensitive to the effect of ART on condom use.

CONCLUSION

The design of ART policy should capitalize on the potential of ART to decrease HIV transmission through institutional arrangements that reward effective prevention programs, thereby raising the likelihood that treatment has beneficial rather than negative external effects.

Randomized controlled trial of intraputamenal glial cell line-derived neurotrophic factor infusion in Parkinson disease

OBJECTIVE

Glial cell line-derived neurotrophic factor (GDNF) exerts potent trophic influence on midbrain dopaminergic neurons. This randomized controlled clinical trial was designed to confirm initial clinical benefits observed in a small, open-label trial using intraputamenal (Ipu) infusion of recombinant human GDNF (liatermin).

METHODS

Thirty-four PD patients were randomized 1 to 1 to receive bilateral continuous Ipu infusion of liatermin 15 microg/putamen/day or placebo. The primary end point was the change in Unified Parkinson Disease Rating Scale (UPDRS) motor score in the practically defined off condition at 6 months. Secondary end points included other UPDRS scores, motor tests, dyskinesia ratings, patient diaries, and (18)F-dopa uptake.

RESULTS

At 6 months, mean percentage changes in "off" UPDRS motor score were -10.0% and -4.5% in the liatermin and placebo groups, respectively. This treatment difference was not significant (95% confidence interval, -23.0 to 12.0, p = 0.53). Secondary end point results were similar between the groups. A 32.5% treatment difference favoring liatermin in mean (18)F-dopa influx constant (p = 0.019) was observed. Serious, device-related adverse events required surgical repositioning of catheters in two patients and removal of devices in another. Neutralizing antiliatermin antibodies were detected in three patients (one on-study and two in the open-label extension).

INTERPRETATION

Liatermin did not confer the predetermined level of clinical benefit to patients with PD despite increased (18)F-dopa uptake. It is uncertain whether technical differences between this trial and positive open-label studies contributed in any way this negative outcome.

Factors affecting breastfeeding practices: applying a conceptual framework

Knowledge about factors affecting breastfeeding can be developed by further research on underlying factors and by drawing out the implications and lessons from intervention research. The use of a conceptual framework to guide this research and the interpretation of results can help us to understand the relative importance of different factors, and how they interact, in turn, helping us to design effective interventions.

Year-round daylight saving and serious or fatal road traffic injuries in children in the north-east of England

BACKGROUND

It has been suggested that year-round daylight saving would reduce road traffic injuries.

METHODS

and results Using 15 years of police data from north-east England, we estimate that 6.9 (95 per cent CI 1.5-12.6) fewer serious or fatal road traffic injuries to child pedestrians would have occurred in this area over this period had year-round daylight saving operated (equivalent to 0.5 per year).

CONCLUSION

The results suggest that operating daylight saving year-round would have a small but tangible effect on the number of serious and fatal road traffic injuries in children in this area. Further work is required to assess the community wide impact of year round daylight saving.

Injury outcome indicators: the development of a validation tool

BACKGROUND

Researchers have previously expressed concern about some national indicators of injury incidence and have argued that indicators should be validated before their introduction.

AIMS

To develop a tool to assess the validity of indicators of injury incidence and to carry out initial testing of the tool to explore consistency on application.

METHODS

Previously proposed criteria were shared for comment with members of the International Collaborative Effort on Injury Statistics (ICE) Injury Indicators Group over a period of six months. Immediately after, at a meeting of Injury ICE in Washington, DC in April 2001, revised criteria were agreed over two days of meetings. The criteria were applied, by three raters, to six non-fatal indicators that underpin the national road safety targets for Canada, New Zealand, and the United Kingdom. Consistency of ratings were judged. CONSENSUS OUTCOME: The development process resulted in a validation tool that comprised criteria relating to: (1) case definition, (2) a focus on serious injury, (3) unbiased case ascertainment, (4) source data for the indicator being representative of the target population, (5) availability of data to generate the indicator, and (6) the existence of a full written specification for the indicator. On application of these criteria to the six road safety indicators, some problems of agreement between raters were identified.

CONCLUSION

This paper has presented an early step in the development of a tool for validating injury indicators, as well as some directions that can be taken in its further development.

Intraputamenal infusion of glial cell line-derived neurotrophic factor in PD: A two-year outcome study

We have shown previously that intraparenchymal infusion of glial cell line-derived neurotrophic factor (GDNF) continuously into the posterior putamen in five Parkinson's disease patients is safe and may represent a new treatment option. Here, we report a continuation of this phase I study. After 2 years of continual GDNF infusion, there were no serious clinical side effects and no significant detrimental effects on cognition. Patients showed a 57% and 63% improvement in their off-medication motor and activities of daily living subscores of the Unified Parkinson's Disease Rating Scale, respectively, and health-related quality-of-life measures (Parkinson's Disease Questionnaire-39 and Short Form-36) showed general improvement over time.

Weight-for-age malnutrition in Indonesian children, 1992-1999

BACKGROUND

This article measures changes over time in Indonesia in the prevalence of moderate and severe child malnutrition, and examines the factors associated with these changes. A child with a weight-for-age Z-score below -2.0 is classified as underweight and either moderately or severely malnourished.

METHODS

A pooled cross-sectional dataset of 163 986 children <5 years of age from the 1992, 1995, 1998, and 1999 Indonesia Socioeconomic Household Surveys was analysed using multivariate logistic regression, and by running separate pooled regressions to calculate the effect of the each of the principal independent variables separately for each year. Robust regression techniques corrected for non-constant variance resulting from multilevel modelling.

RESULTS

The overall percentage of children <5 years that are underweight decreased from 37.7% in 1992 to 28.5% in 1999. Nearly all of the gains occurred in children over one year of age. Child nutritional status improved for all major social groups in Indonesia. There was no measurable general effect of the 1997-1999 East Asian economic crisis on levels of underweight children.

CONCLUSIONS

Disparities among social and economic groups have narrowed over time in Indonesia; the relatively high risk of male children compared with females has also decreased. Maternal education and economic status-as measured by quintile of adjusted per-capita household expenditures-have continued to be very strong predictors of children's nutritional outcomes.

Dopamine agonist switching in Parkinson's disease

There are a number of situations for patients with Parkinson's disease in which a safe and efficacious switch from treatment with one dopamine agonist to another may be required. This article explores reasons for making such a switch, and provides practical guidance on performing it.

MRI directed bilateral stimulation of the subthalamic nucleus in patients with Parkinson's disease

OBJECTIVE

Bilateral chronic high frequency deep brain stimulation (DBS) of the subthalamic nucleus (STN) has emerged as an appropriate therapy for patients with advanced Parkinson's disease refractory to medical therapy. Advances in neuroimaging and neurophysiology have led to the development of varied targeting methods for the delivery of this treatment. Intraoperative neurophysiological and clinical monitoring is regarded by many to be mandatory for accurate STN localisation. We have examined efficacy of bilateral STN stimulation using a predominantly magnetic resonance imaging (MRI)-directed technique.

METHODS

DBS leads were stereotactically implanted into the STN using an MRI directed method, with intraoperative macrostimulation used purely for adjustment. The effects of DBS were evaluated in 16 patients followed up to 12 months, and compared with baseline assessments. Assessments were performed in both off and on medication states, and were based on the Unified Parkinson's Disease Rating Scale (UPDRS) and timed motor tests. Functional status outcomes were examined using the PDQ-39 quality of life questionnaire. A battery of psychometric tests was used to assess cognition.

RESULTS

After 12 months, stimulation in the off medication state resulted in significant improvements in Activities of Daily Living and Motor scores (UPDRS parts II and III) by 62% and 61% respectively. Timed motor tests were significantly improved in the off medication state. Motor scores (UPDRS part III) were significantly improved by 40% in the on medication state. Dyskinesias and off duration were significantly reduced and the mean dose of L-dopa equivalents was reduced by half. Psychometric test scores were mostly unchanged or improved. Adverse events were few.

CONCLUSIONS

An MRI directed targeting method for implantation of DBS leads into the STN can be used safely and effectively, and results are comparable with studies using intraoperative microelectrode neurophysiological targeting. In addition, our method was associated with an efficient use of operating time, and without the necessary costs of microelectrode recording.

MRI-directed subthalamic nucleus surgery for Parkinson's disease

The subthalamic nucleus (STN) is now regarded as the optimal surgical target for the treatment of medically refractory idiopathic Parkinson's disease. In our center, a predominantly MRI-directed method has been developed for targeting the STN. The STN is localized on T2-weighted images from a 1.5-T MRI scanner. Long acquisition, high-resolution images are acquired in both the axial and coronal planes under strict stereotactic conditions with the patient under general anesthesia. The boundary of STN is co-registered in both planes to give optimal 3-dimensional target definition. Stereotactic coordinates of the dorsolateral STN are recorded and the trajectory is planned down the axis of the nucleus in the coronal plane. Initially, per-operative macrostimulation was used for adjustment at the target prior to unilateral subthalamotomy in 26 patients. Five patients were lost to follow-up. Assessments of the lesions in post-operative images confirmed successful localisation of the lesions within the dorsolateral STN in all of the remaining 21 cases. In a subsequent series of 19 patients treated by deep brain stimulation (DBS), unilateral in 1 patient and bilateral in 18, the STN was targeted using the same MRI-directed method, guide tubes and radio-opaque stylettes were implanted, and target verification was entirely MRI-based. Following implantation of the guide tubes and stylettes, assessments of the per-operative MRI images for the 37 STN targetings confirmed a mean target error, between the stylette and the desired target in the axial plane, of 0.3 mm mediolaterally (SD = 0.4) and 0.4 mm anteroposteriorly (SD = 0.4), with median errors of 0.5 mm. This study demonstrates that MRI-directed targeting of the STN through guide tubes is accurate, and allows direct verification and corrections as necessary. Cumulative frequencies predict that the majority of DBS electrodes placed in this manner will be within 0.5 mm of the planned target. Because physiological methods are not required, the whole procedure can be performed under general anesthesia. We feel that planning with reference to a standard atlas is unreliable and not significantly helped by the addition of microelectrode recording, the accuracy of which in the axial plane is dependent upon the distance between the recording trajectories, which is typically 2 mm.

Direct brain infusion of glial cell line-derived neurotrophic factor in Parkinson disease

Glial cell line-derived neurotrophic factor (GDNF) is a potent neurotrophic factor with restorative effects in a wide variety of rodent and primate models of Parkinson disease, but penetration into brain tissue from either the blood or the cerebro-spinal fluid is limited. Here we delivered GDNF directly into the putamen of five Parkinson patients in a phase 1 safety trial. One catheter needed to be repositioned and there were changes in the magnetic resonance images that disappeared after lowering the concentration of GDNF. After one year, there were no serious clinical side effects, a 39% improvement in the off-medication motor sub-score of the Unified Parkinson's Disease Rating Scale (UPDRS) and a 61% improvement in the activities of daily living sub-score. Medication-induced dyskinesias were reduced by 64% and were not observed off medication during chronic GDNF delivery. Positron emission tomography (PET) scans of [(18)F]dopamine uptake showed a significant 28% increase in putamen dopamine storage after 18 months, suggesting a direct effect of GDNF on dopamine function. This study warrants careful examination of GDNF as a treatment for Parkinson disease.

Unilateral subthalamotomy in the treatment of Parkinson's disease

Hyperactivity in the subthalamic nucleus (STN) is seen in animal models of Parkinson's disease, and lesioning of the STN dramatically relieves the animal's parkinsonism. Deep brain stimulation (DBS) of the STN is an effective treatment for patients with advanced Parkinson's disease. We have studied the effects of a unilateral lesion placed in the STN in predominantly hemi-parkinsonian patients. Twenty-one patients with advanced idiopathic Parkinson's disease were studied. Seventeen had asymmetrical tremor-dominant Parkinson's disease and four had bilateral disease. All patients underwent radiofrequency lesioning of the dorsolateral part of the STN under stereotactic guidance. The four patients with bilateral disease had, in addition, an electrode implanted contralaterally in the STN. Twenty-one patients have been followed for a minimum of 12 months. Clinical evaluation included the use of the Unified Parkinson's Disease Rating Scale (UPDRS) before and after surgery. Post-operative high-resolution MRI was performed in each patient to confirm lesion location, and this was correlated with clinical outcome. There was improvement in contralateral tremor, rigidity and bradykinesia in all patients followed for 6, 12 and 24 months, with the effect on tremor being greatest. L-dopa equivalent daily intake was approximately halved, and this resulted in a significant reduction in dyskinesia. Psychometric test scores were mostly unchanged or improved. All lesions were successfully located in the dorsolateral STN. Nineteen of the 21 lesions extended beyond the STN to involve pallidofugal fibres (H2 field of Forel) and the zona incerta (ZI). Lesion-induced dyskinesias were not a management problem except in one patient, whose lesion was confined to the STN. This patient was successfully treated with deep brain stimulator placement in the region of H2/ZI. Unilateral STN lesions can be made safely and are an effective alternative to thalamotomy, pallidotomy and unilateral STN DBS for the treatment of asymmetrical tremor-dominant advanced Parkinson's disease. Com bined lesioning of the dorsolateral STN and H2/ZI is particularly effective.

First wave PMS pilots: a critical analysis of documentation

Contracts and interim local evaluation reports for the 14 first wave PMS pilots in Northern and Yorkshire region were analysed by documentary analysis. Both contracts and reports were found to vary considerably in size and scope. Most contracts contained aims and objectives that were too broad or vague to guide project management and they lacked useful milestones. This made it difficult to identify criteria for measuring success. The local evaluation reports were also of variable quality. It is recommended that contracts should be accompanied by a development plan containing specific objectives, timescale and process for implementation as well as an evaluation strategy. The relative importance of different targets should be agreed and specified at the outset, to allow weighting of partial success, where some objectives, but not others, are achieved. Project milestones would be made explicit and measurable in the development plan. More clarity in contracts and evaluation for future pilots is essential.

Effectiveness and cost effectiveness of counselling in primary care

BACKGROUND

Counsellors are prevalent in primary care settings. However, there are concerns about the clinical and cost-effectiveness of the treatments they provide, compared with alternatives such as usual care from the general practitioner, medication or other psychological therapies.

OBJECTIVES

To assess the effectiveness and cost effectiveness of counselling in primary care by reviewing cost and outcome data in randomised controlled trials, controlled clinical trials and controlled patient preference trials of counselling interventions in primary care, for patients with psychological and psychosocial problems considered suitable for counselling.

SEARCH STRATEGY

The original search strategy included electronic searching of databases (including the CCDAN Register of RCTs and CCTs) along with handsearching of a specialist journal. Published and unpublished sources (clinical trials, books, dissertations, agency reports etc.) were searched, and their reference lists scanned to uncover further controlled trials. Contact was made with subject experts and CCDAN members in order to uncover further trials. For the updated review, searches were restricted to those databases judged to be high yield in the first version of the review: MEDLINE, EMBASE, PSYCLIT and CINAHL, the Cochrane Controlled Trials register and the CCDAN trials register.

SELECTION CRITERIA

All controlled trials comparing counselling in primary care with other treatments for patients with psychological and psychosocial problems considered suitable for counselling. Trials completed before the end of June 2001 were included in the review.

DATA COLLECTION AND ANALYSIS

Data were extracted using a standardised data extraction sheet. The relevant data were entered into the Review Manager software. Trials were quality rated, using CCDAN criteria, to assess the extent to which their design and conduct were likely to have prevented systematic error. Continuous measures of outcome were combined using standardised mean differences. An overall effect size was calculated for each outcome with 95% confidence intervals. Continuous data from different measuring instruments were transformed into a standard effect size by dividing mean values by standard deviations. In view of the diversity of counselling services in primary care (the range of treatments, patients and practitioners) tests of heterogeneity were done to assess the feasibility of aggregating measures of outcome from trials. Sensitivity analyses were undertaken to test the robustness of the results.

MAIN RESULTS

Seven trials were included in the review. The main analyses showed significantly greater clinical effectiveness in the counselling group compared with 'usual care' in the short-term (standardised mean difference -0.28, 95% CI -0.43 to -0.13, n=772, 6 trials) but not the long-term (standardised mean difference -0.09, 95% CI -0.27 to 0.10, n=475, 4 trials). Levels of satisfaction with counselling were high. Four studies reported similar total costs associated with counselling and usual care over the long-term. However, the economic analyses were likely to be underpowered.

REVIEWER'S CONCLUSIONS

Counselling is associated with modest improvement in short-term outcome compared to 'usual care', but provides no additional advantages in the long-term. Patients are satisfied with counselling, and it may not be associated with increased costs.

Central chemosensitivity and breathing asleep in unilateral medullary lesion patients: comparisons to animal data

The rostro-ventrolateral medulla (RVLM) is a site of chemosensitivity in animals; such site(s) have not been defined in humans. We studied the effect of unilateral focal lesions in the rostrolateral medulla (RLM) of man, on the ventilatory CO(2) sensitivity and during awake and sleep breathing. Nine patients with RLM lesions (RLM group), and six with lesions elsewhere (non-RLM group) were studied. The ventilatory CO(2) sensitivity was lower in the RLM compared with the non-RLM group (mean (S.D.), RLM, 1.4 (0.9), non-RLM 3.0 (0.6) L min(-1) mmHg(-1)). In both groups resting breathing was normal. During sleep all RLM patients had frequent arousals, four had significant sleep disordered breathing (SDB), only one non-RLM patient had SDB. Our findings in humans resemble those in animals with focal RVLM lesions. This review provides evidence that in humans there is an area of chemosensitivity in the RLM. We propose that in humans, dorsal displacement of the RVLM area of chemosensitivity in animals, arises from development of the olive plus the consequences of the evolution of the cerebellum/inferior peduncle.

Delayed cerebral edema and fatal coma after minor head trauma: role of the CACNA1A calcium channel subunit gene and relationship with familial hemiplegic migraine

Trivial head trauma may be complicated by severe, sometimes even fatal, cerebral edema and coma occurring after a lucid interval ("delayed cerebral edema"). Attacks of familial hemiplegic migraine (FHM) can be triggered by minor head trauma and are sometimes accompanied by coma. Mutations in the CACNA1A calcium channel subunit gene on chromosome 19 are associated with a wide spectrum of mutation-specific episodic and chronic neurological disorders, including FHM with or without coma. We investigated the role of the CACNA1A gene in three subjects with delayed cerebral edema. Two subjects originated from a family with extreme FHM, and one subject was the previously asymptomatic daughter of a sporadic patient with hemiplegic migraine attacks. In all three subjects with delayed severe edema, we found a C-to-T substitution resulting in the substitution of serine for lysine at codon 218 (S218L) in the CACNA1A gene. The mutation was absent in nonaffected family members and 152 control individuals. Haplotype analysis excluded a common founder for both families. Neuropathological examination in one subject showed Purkinje cell loss with relative preservation of granule cells and sparing of the dentate and inferior olivary nuclei. We conclude that the novel S218L mutation in the CACNA1A calcium channel subunit gene is involved in FHM and delayed fatal cerebral edema and coma after minor head trauma. This finding may have important implications for the understanding and treatment of this dramatic syndrome.

Survey of the prescribing of chemoprophylaxis to index cases of invasive meningococcal disease

Chemoprophylaxis is given to contacts of cases of invasive meningococcal disease to reduce the risk of secondary cases by eradicating carriage. In the United Kingdom index cases are also recommended to receive chemoprophylaxis. This is usually undertaken by the clinical team managing the case. One hundred and fifty cases of probable meningococcal infection notified to the consultants in communicable disease control in a local health authority were reviewed to identify the proportion receiving chemoprophylaxis and to examine the final clinical outcome, in terms of diagnosis, of each case. Twenty-five per cent of notified cases (37) did not receive chemoprophylaxis and this proportion varied significantly between three local hospitals. We estimate that 15 of the 37 index cases who did not receive chemoprophylaxis were likely to have had invasive meningococcal disease.
