Anti-Epileptic Medication Exposure Influences Functional Status in New Zealand Stroke Patients: A Retrospective Population-Level Study

Background

Patients who develop seizures after stroke have disproportionately poorer outcomes and increased mortality.

Objective

Our objective was to investigate whether exposure to anti-epileptic medications influenced long-term functional status after stroke.

Methods

We used linked health administrative data from a cohort of adult stroke patients in New Zealand. Demographics and prescription information were obtained from the National Minimum Dataset and Pharmaceutical Collection, respectively. Activities of daily living (ADL) scores for the same patients were obtained using the International Resident Assessment Instrument. Beta regression was used to investigate the relationship between anti-epileptic drug (AED) exposure and functional status.

Results

The study included 3606 patients with a single ischaemic stroke between 2012 and 2017. In total, 15% were dispensed an AED in the 3 months before or after stroke. The adjusted odds ratio (OR) for AED exposure was 1.29 (95% confidence interval [CI] 1.15–1.45). Overall AED exposure, categorical body mass index (BMI), ethnicity, length of hospital stay, and exposure to paracetamol, opioids, anti-psychotics, and anti-nausea medications were significantly associated with changes in the mean ADL score percentages. Considering the exposure timeframe, the ORs for AED exposure only after stroke and for exposure both before and after stroke were 1.52 (95% CI 1.31–1.78) and 1.09 (95% CI 0.93–1.27), respectively.

Conclusion

Stroke patients with AED exposure had greater odds of a higher ADL score, indicating a poorer long-term functional status than those unexposed to AEDs. The timeframe of exposure impacted on functional status, with patients exposed only after stroke having increased odds of higher ADL scores than those exposed both before and after stroke.

Long-term evaluation of community health promotion: using capacity building as an intermediate outcome measure

OBJECTIVES

Between 2001 and 2012, the health authority of Hamburg-Eimsbüttel carried out a health promotion programme for children and their parents in a disadvantaged neighbourhood called Lenzsiedlung. The programme consisted of different action fields aiming at sustainable establishment of community capacities.

STUDY DESIGN

The research goal was the long-term assessment of community capacities with a newly developed instrument 'KEQ' (KEQ = Kapazitätsentwicklung im Quartier/capacity building in small areas/neighbourhoods). Practitioners and researchers wanted to know whether community capacities could be increased, which changes occurred during the programme and whether processes of capacity building could be maintained. Research results were also used for the continuous adjustment of the programme to community needs.

METHODS

Three surveys on community capacities were conducted (t1: June 2006 [including a retrospective measurement of t0: 2001]; t2: June 2008; and t3: November 2011), each directed to 40-60 stakeholders of the Lenzsiedlung. The instrument consists of five domains (participation, local leadership, available resources, networking and cooperation and health care) with a total of 51 items.

RESULTS

For the community capacities, we found a positive trend from 2001 to 2006 supported by data from a documentary analysis over the same period of time. Then, 2006-2011 was a phase of consolidation with only slight improvements (e.g. in the particularly important domain 'health care').

CONCLUSIONS

The results show the feasibility of a community health promotion programme and its maintenance over a period of 10 years. However, Lenzgesund was not the sole programme in the neighbourhood during the period of observation, so that not all improvements in capacities are directly assignable to the interventions. The instrument mainly reflects the possibly one-sided perspective of the interviewed experts from the community.

Self-assessments and determinants of HRQoL in a German MS population

OBJECTIVES

The importance of health-related quality of life (HRQoL) in multiple sclerosis (MS) is widely acknowledged. In 2015, a multicenter study was launched to assess the HRQoL and coping styles of chronically ill persons in Germany. The aims of this paper were (i) to describe how persons affected by MS assess their HRQoL and (ii) find out sociodemographic and disease-specific determinants of HRQoL.

MATERIALS AND METHODS

A quantitative survey (optionally per paper-pencil or online) was conducted between March and October 2015 in Germany. Recruitment ways were as follows: Associations of the German Multiple Sclerosis Society (DMSG), medical practices specialized in neurology/MS, hospitals, public events, social networks, and self-help clearinghouses. To measure HRQoL, the Multiple Sclerosis International Quality of Life (MusiQoL) questionnaire and the short form of the Fear of Progression Questionnaire (FoP-Q) were used.

RESULTS

A total of 1220 individuals with MS participated in the study. Frequent problems reported were related to activities of daily living as well as sentimental and sexual life. Multiple regression analyses identified disease severity and comorbidity-in different directions (positive and negative)-as the strongest factors in predicting activities of daily living, symptoms, sentimental and sexual life, and reject. The demographic variables sex, age, education, and employment status also have different impact on the HRQoL.

CONCLUSIONS

Using HRQoL measures can be feasible outcomes in addition to clinical assessments of MS and other chronic diseases and can help better managing the care. Some challenges have to be taken into account involving patients and the limitations of our empirical study.

[How many patient transfer rooms are necessary for my OR suite? : Effect of the number of OR transfer rooms on waiting times and patient throughput in the OR - analysis by simulation]

INTRODUCTION

In most hospitals the operating rooms (OR) are separated from the rest of the hospital by transfer rooms where patients have to pass through for reasons of hygiene. In the OR transfer room patients are placed on the OR table before surgery and returned to the hospital bed after surgery. It could happen that the number of patients who need to pass through a transfer room at a certain point in time exceed the number of available transfer rooms. As a result the transfer rooms become a bottleneck where patients have to wait and which, in turn, may lead to delays in the OR suite. In this study the ability of a discrete event simulation to analyze the effect of the duration of surgery and the number of ORs on the number of OR transfer rooms needed was investigated.

METHODS

This study was based on a discrete event simulation model developed with the simulation software AnyLogic®. The model studied the effects of the number of OR transfer rooms on the processes in an OR suite of a community hospital by varying the number of ORs from one to eight and using different surgical portfolios. Probability distributions for the process duration of induction, surgery and recovery and transfer room processes were calculated on the basis of real data from the community hospital studied. Furthermore, using a generic simulation model the effect of the average duration of surgery on the number of OR transfer rooms needed was examined.

RESULTS

The discrete event simulation model enabled the analysis of both quantitative as well as qualitative changes in the OR process and setting. Key performance indicators of the simulation model were patient throughput per day, the probability of waiting and duration of waiting time in front of OR transfer rooms. In the case of a community hospital with 1 transfer room the average proportion of patients waiting before entering the OR was 17.9 % ± 9.7 % with 3 ORs, 37.6 % ± 9.7 % with 5 ORs and 62.9 % ± 9.1 % with 8 ORs. The average waiting time of patients in the setting with 3 ORs was 3.1 ± 2.7 min, with 5 ORs 5.0 ± 5.8 min and with 8 ORs 11.5 ± 12.5 min. Based on this study the community hospital needs a second transfer room starting from 4 ORs so that there is no bottleneck for the subsequent OR processes. The average patient throughput in a setting with 4 ORs increased significantly by 0.3 patients per day when a second transfer room is available. The generic model showed a strong effect of the average duration of surgery on the number of transfer rooms needed.

CONCLUSION

There was no linear correlation between the number of transfer rooms and the number of ORs. The shorter the average duration of surgery, the earlier an additional transfer room is required. Thus, hospitals with shorter duration of surgery and fewer ORs may need the same or more transfer rooms than a hospital with longer duration of surgery and more ORs. However, with respect to an economic analysis, the costs and benefits of installing additional OR transfer rooms need to be calculated using the profit margins of the specific hospital.

[Capacity Building for Prevention and Health Promotion for Children and Parents in a Deprived Urban Quarter: Lenzgesund]

In 2005 the local health authority Hamburg-Eimsbüttel developed a prevention programme for the disadvantaged quarter "Lenzsiedlung" which has been implemented by the stakeholders committee "Round Table Lenzgesund" and other partners led by the health authority. The Department of Medical Sociology and Health Economics of the University Medical Centre had taken on the accompanying analysis and long-term evaluation with a mixture of qualitative and quantitative methods for health reporting and evaluation and a new instrument for measuring capacity building in the quarter (KEQ).

[Customer and patient satisfaction. An appropriate management tool in hospitals?]

Recently, the concept of patient satisfaction has been established as an essential part of the quality management of hospitals. Despite the concept's lack of theoretical and methodological foundations, patient surveys on subjective hospital experiences contribute immensely to the improvement of hospitals. What needs to be considered critically in this context is the concept of customer satisfaction for patients, the theoretical integration of empirical results, the reduction of false satisfaction indications and the application of risk-adjusted versus naïve benchmarking of data. This paper aims to contribute to the theoretical discussion of the topic and to build a basis for planning methodologically sound patient surveys.

Bottle microresonator with actively stabilized evanescent coupling

The evanescent coupling of light between a whispering-gallery-mode bottle microresonator and a subwavelength-diameter coupling fiber is actively stabilized by means of the Pound-Drever-Hall technique. We demonstrate the stabilization of a critically coupled resonator with a control bandwidth of 0.1 Hz, yielding a residual transmission of (9±3)×10(-3) for more than an hour. Simultaneously, the frequency of the resonator mode is actively stabilized.

Complementary therapy use in patients with glioma: an observational study

OBJECTIVE

Despite novel multimodal therapeutic approaches, the vast majority of glial tumors are not curable. Patients may search for complementary therapies in order to contribute to the fight against their disease or to relieve symptoms induced by their brain tumor. The extent of the use of complementary or alternative therapies, the patients' rationale behind it, and the cost of complementary therapy for gliomas are not known. We used a questionnaire and the database of the German Glioma Network to evaluate these questions.

METHODS

A total of 621 questionnaires were available for evaluation from patients with glial tumors of WHO grades II to grade IV. The patients were recruited from 6 neuro-oncologic centers in Germany. Complementary therapy was defined as methods or compounds not used in routine clinical practice and not scientifically evaluated.

RESULTS

Forty percent of the responding patients reported the use of complementary therapies. Significant differences between the group of complementary therapy users and nonusers were seen with respect to age (younger > older), gender (female > male), and education (high education level > low education level). The motivation for complementary therapy use was not driven by unsatisfactory clinical care by the neuro-oncologists, but by the wish to add something beneficial to the standard of care.

CONCLUSIONS

In clinical practice, patients' use of complementary therapies may be largely overseen and underestimated. The major motivation is not distrust in conventional therapies. Neuro-oncologists should be aware of this phenomenon and encourage an open but critical dialogue with their patients.

Non-conventional treatments sought by patients after surgery for intramedullary spinal cord tumors

OBJECTIVE

Despite modern microsurgical techniques and interdisciplinary treatment options, intramedullary spinal cord tumors often lead to profound neurological deficits. Some patients may search for non-scientific or unconventional therapeutic options to treat the symptoms induced by the tumor itself or arising from treatment. The extent of non-scientific therapy use, the rationale behind it, and costs of these forms of therapy are unknown.

METHODS

A questionnaire consisting of 20 questions was sent to 60 patients of a single neurosurgical center who had undergone surgery for an intramedullary spinal cord tumor. A retrospective study was carried out based on this data. Histological findings ranged from ependymoma (52.9%), hemangioblastoma (17.6%), cavernoma (14.7%), astrocytoma (8.8%), oligodendroglioma (2.9%) to ganglioglioma (2.9%). Non-scientific therapy was defined as a method not used in routine clinical practice for the treatment of symptoms induced by intramedullary spinal cord tumors.

RESULTS

A total of 38 questionnaires was returned. About 55.3% of the patients claimed to use non-scientific therapies. No significant difference between histological types and the percentage of alternative therapy use was detected. There was a gender difference. One third (non user group) to one fourth (user group) did not feel adequately informed about their disease. The monthly costs for non-scientific therapies ranged from 50 to 500 Euros. The main motive for the use of non-scientific therapies was the wish to try everything possible.

CONCLUSION

In the daily clinical routine, patients' use of non-scientific therapies may be largely overlooked and underestimated. Neurooncologists should be aware of this phenomenon and encourage an open but critical dialogue with their patients.

[Empowerment by capacity building in urban quarters--first results and assessment of a new standardised instrument]

AIMS

Capacity building is regarded as an intermediate outcome and success parameter for community health promotion and empowerment. The first aim of the study was the development and examination of a tool to measure capacity building in the context of a programme of health promotion for children and parents in a socially disadvantaged quarter in Hamburg (about 3000 residents, 60% with migration background). The second aim was to measure capacity building within a period of five years.

METHOD

A survey was carried out with 27 professionals from the health and social field. Dimensions of the instrument were: citizen participation, local leadership, available resources, networking and co-operation, support of residents. At the same time, we tested to what extent the instrument is suitable for resident surveys. Furthermore, pretest instrument and results were discussed with our advisory board regarding potential improvements.

RESULTS

The result of the project, in addition to its practical use in the quarter, consists of the generation of a psychometrically tested instrument to measure capacity building. Furthermore, the experience contributed to the expertise on how such a study can be conducted. A comparison of the situation in 2006 with the situation in 2001 showed considerable improvements in all dimensions of capacity building in the quarter.

CONCLUSION

Establishing the instrument on a long-term basis calls for more intensive examination not only of the chances, but also the limitations of the tool. We mainly attribute the overall positive picture that was gained within a period of five years to the generally supportive climate of development in the quarter as well as to the strong and continuous commitment of individual persons involved.

[The economic benefits of self-help associations]

OBJECTIVES

This article primarily reflects on the economic benefits of self-help associations, and the problems of their adequate evaluation.

METHODS

We present a critical discussion of the concepts in the economic evaluation and empiricism by secondary analysis of data available based on a review of published studies as well as the re-analysis of primary data from our Hamburg study in 2003 (n=345 or 52.4% of the self-help associations registered in Hamburg).

RESULTS

Most approaches to evaluate the economic benefits of self-help groups were inspired by the idea of output-related, cost-benefit analysis, by which activities of members were monetarily estimated. Projected for Hamburg, the productive performance amounts to nearly 1.8 million Euro per month, and 21.5 million per year. Furthermore, additional voluntary commitment can be mobilized at 300,000 Euro per month.

CONCLUSION

All calculations are based on some assumptions (e.g., coefficient of productivity, wages) which cannot be finally verified. In view of the state of research reviewed we strongly recommend to bring forward both outcome-oriented approaches of economic evaluation, and new representative studies of self-help groups for Germany as a whole.

Patient-reported outcomes in hernia repair

BACKGROUND

The project aimed at testing the feasibility of a quality improvement system based on patient-reported outcomes in short-stay surgery for groin hernia repair.

METHODS

In two centres for short-stay surgery all patients referred for hernia repair were surveyed between August 1999 and January 2002. Patients reported on health-related quality of life (SF-36), symptoms (Hernia Symptom Checklist, HSCL) and other indicators pre-operatively (T0) and 14 days (T1) and 6 months post-operatively (T2). Three of the eight SF-36 subscales (physical functioning, bodily pain, and role physical) and the HSCL at T2 were considered as main outcome indicators. The main outcomes were analysed by generalized linear models with regard to predictors.

RESULTS

At T0 a total of 342 hernia patients were included. The response rate at T2 was 54.1% (92.4% males, 58.6 years of age). At T2 only 21.1% did not report complaints (i.e. haematoma, pain, numbness) post-operatively. The overall positive course is reflected by the HSCL: from 32.4% pre-operatively, it rises slightly to 38.5% at T1 and decreases to 10.6% at T2 (T0-T2: P < 0.001). The SF-36 subscales "physical functioning", "bodily pain", and "role physical" showed the same course over time (slight decrease of health-related quality of life at T1 and large increase at T2). The main patient-reported outcomes were mainly influenced by the pre-operative level, age, and self-reported post-operative complaints.

CONCLUSION

The low response rate was mainly due to non-delivery of questionnaires at T1 during the regular post-operative visit by the operating physician. Though non-response occurs under conditions of routine care, meaningful information was gained which should be used for quality improvement activities. Because the pre-operative level is a major determinant of the post-operative health outcomes, the prospective pre-post measurement should be standard, in case institutional comparisons are intended.

[Social factors influencing participation in self-help groups or organisations--results from selected questions for the health monitor]

OBJECTIVES

Using selected data collected by the Health Monitor (Bertelsmann-Stiftung) from 1,539 adults aged between 18 and 79 years this article describes which social factors have an impact on participation in self-help groups or organisations. Furthermore, questions about the length of participation, fields of self-help activity, and their usefulness were analysed.

METHODS

All participants were approached in written form. The questionnaire included 103 health-related items (6 about self-help), and 15 demographic characteristics. The sample was weighted statistically by federal state, sex and age.

RESULTS

4.1% stated to be a member of self-help organisations for chronically ill or disabled people. On the whole, 9.1% have participated in self-help activities during their lifetime (currently active: 2.8%). Membership in self-help organisations increases with age, social class and according to personal involvement, whereas participation in self-help groups is quite different. The rate of participation of women is nearly twice as high as that of men (11.1 versus 6.9%). Generally, participation in self-help groups was also rated positively, but assessments vary with social class and the length of using them.

CONCLUSION

Particularly with regard to the distribution of self-help participants depending on social class there are some discrepancies to other studies. These differences can supposedly be ascribed to methodical factors (e. g., social class index, sample size).

[Work-satisfaction and Health of Hospital Nursing and Medical Personnel]

The implementation of new service demands and increasing rationalisation measures exercise stress and pressure on medical and nursing personnel in German hospitals. However, their satisfaction and health are important quality criteria in the ranking of a hospital. Basing on the introduction of a new tool, an inquiry was conducted among the medical and nursing personnel of two hospitals (A and B) in respect of the quality of their working conditions. The scope of the questionnaires covered the nature and kind of the work, opportunities of professional success, management of co-operation and conflicts, physical and structural obstacles to smooth working as well as the management of quality. Finally, a scale of complaints and a burn-out scale served to assess the personnel's subjective health situation. The questionnaire was submitted in hospital A between November 1999 and February 2000 to a total of 39 doctors (58 % compliance) and 84 nursing personnel (47 % compliance) of the specialist departments concerned with internal medicine, rheumatology, urology, general and accident surgery. In hospital B the questionnaire was completed between March and July 2001 by a total of 40 doctors (54 %) and 91 nursing personnel (68 %) of two departments of internal medicine, surgery, neurosurgery and gynaecology. Comparable to other studies, the nursing personnel in both the hospitals rated the working conditions more negatively than the medical personnel. The differences, however, are more of a quantitative (number of frequency of problems) than of a qualitative nature (type or kind of problems). With both groups, problems connected with structural difficulties in working and with quality management were by far most important while the nursing personnel also underlined physical stress. Individual health condition were also classified more negatively by the nursing personnel than by the doctors, and the overall physical complaints of the nursing personnel were generally greater than with the average population, whereas medical personnel registered fewer complaints. Health promotion measures in hospitals may help to prevent negative developments. Such measures are too rarely translated into reality.

[Quality evaluation from the patient viewpoint--exemplary results from the European WHO Project "Health-Promoting Hospitals"]

This article has two objectives: first of all, to present the European WHO project "Health Promotion in Hospitals" in a general way and secondly, to report on results of empirical concomitant research on a sub-project on quality assessment from the patient's viewpoint in a Hamburg member hospital of the international WHO pilot project and to present the essential partial aims of this approach to health promotion. An interim report on the international pilot project showed clearly that among all the realisation projects those are the most frequent ones that aim at promoting the health of patients (87 of a total 181). We report on one of these projects (partly sponsored by the North German Centre of Public Health). Focus is on the results of a quantitative query among patients (n = 157 = 58% response rate). The methods on which the study is based as well as the relevant limitations of its representative nature are outlined. Essential results quoted are the assessments made by the patients themselves taking into consideration 11 dimensions of hospital quality. It becomes evident that action should be taken in the area of several communicative dimensions and in hospital facilities. The results of the inquiry provided the basis for hospital quality improvements. An internal project group within the hospital worked out recommendations that have since been translated into reality to a large extent.
