"Effectiveness'' in Finnish healthcare studies

AIMS

Evaluation of effectiveness is connected with prevailing paradigms, and the breadth and perspective applied therein exhibit differences. Effectiveness refers to the extent to which a given intervention or service produces health outcomes in individuals to whom it is offered. The aim of this paper is to clarify the concept of effectiveness evaluation in health care and present the ways in which Finnish healthcare studies use the concept of effectiveness.

METHODS

Through a systematic review of Finnish scientific journals in the healthcare research field, 25 original studies, 35 review articles, and 20 discussion papers were acquired. The inclusion criterion was that the word ;;effectiveness'' was presented in the title or abstract.

RESULTS

In this study the effects of actions were evaluated through the process (outputs) or through the outcomes (harms and benefits). The word ;;effectiveness'' is widely used in healthcare research in Finland; mostly in studies of orthopaedics, health services research, physiotherapy, rehabilitation, and psychiatry, yet the concept was explicitly defined in only three papers. Most studies used both process and outcome measures. The outcome indicators were usually disease-specific. Papers presenting only process outputs clearly showed a health service producer's perspective. Health-related quality of life as an outcome indicator was rarely used.

CONCLUSIONS

In Finnish healthcare studies, the concept of effectiveness was rarely defined and effectiveness measures were often vague or even nonexistent. The meaning of the term had to be interpreted from the study methodology, measures, and indicators.

Nurses' intentions to leave nursing in Finland

The shortage of nurses is a problem in many countries. We examined how factors related to wage, work, job satisfaction/dissatisfaction, and workplace or demographic factors were associated with nurses' intentions to switch from health care to non-health-care roles. Wage and share of income from shift work were negatively and statistically significantly related to nurses' intention to leave the health care sector. However, some non-pecuniary variables, such as Possibility for Specialisation gained a positive, statistically significant association with job satisfaction and thereby decreased intention to change work sector. Therefore, not only economic factors influence the labour supply of nurses.

Clients' and workers' perceptions on clients' functional ability and need for help: home care in municipalities

The aim of the study was to compare clients' and named home care (HC) workers' perceptions of clients' functional ability (FA) and need for help and to analyse which client- and municipality-related factors are associated with perceptions of client's FA. The total of 686 Finnish HC clients was interviewed in 2001. Further, the questionnaire was sent to 686 HC workers. FA was assessed by activities of daily living (ADL), which included both basic/physical (PADL) and instrumental (IADL) activities. The association between client's FA and municipality-related variables was analysed by using hierarchical logistic regression models. The findings indicated that clients' and HC-workers' perceptions about what the clients were able to do were similar in the PADL functions, but perceptions differed when it comes to the IADL functions for mobility and in climbing stairs. A smaller proportion of clients compared with HC workers assessed themselves to be in need of help in all ADL functions. Use of home help and bathing services increased the probability of belonging to the 'poor' FA class while living alone and small size of municipality decreased the probability. The study indicates that although clients and workers assessed client's FA fairly similarly, there were major differences in perceptions concerning clients' needs for help in ADL functions. Clients' and workers' shared view of need for help forms a basis for high-quality care. Therefore, the perception of both the clients and workers must be taken into account when planning care and services. There was also variation in clients' FA between municipalities, although only the size of municipality had some association with the variation. The probability that clients with a lower FA are cared for in HC is higher if the clients live in large- rather than small-sized municipalities. This may reflect a better mix of services and resources in large-sized municipalities.

Cost-effectiveness analysis of guidelines for antihypertensive care in Finland

BACKGROUND

Hypertension is one of the major causes of disease burden affecting the Finnish population. Over the last decade, evidence-based care has emerged to complement other approaches to antihypertensive care, often without health economic assessment of its costs and effects. This study looks at the extent to which changes proposed by the 2002 Finnish evidence-based Current Care Guidelines concerning the prevention, diagnosis, and treatment of hypertension (the ACCG scenario) can be considered cost-effective when compared to modelled prior clinical practice (the PCP scenario).

METHODS

A decision analytic model compares the ACCG and PCP scenarios using information synthesised from a set of national registers covering prescription drug reimbursements, morbidity, and mortality with data from two national surveys concerning health and functional capacity. Statistical methods are used to estimate model parameters from Finnish data. We model the potential impact of the different treatment strategies under the ACCG and PCP scenarios, such as lifestyle counselling and drug therapy, for subgroups stratified by age, gender, and blood pressure. The model provides estimates of the differences in major health-related outcomes in the form of life-years and costs as calculated from a 'public health care system' perspective. Cost-effectiveness analysis results are presented for subgroups and for the target population as a whole.

RESULTS

The impact of the use of the ACCG scenario in subgroups (aged 40-80) without concomitant cardiovascular and related diseases is mainly positive. Generally, costs and life-years decrease in unison in the lowest blood pressure group, while in the highest blood pressure group costs and life-years increase together and in the other groups the ACCG scenario is less expensive and produces more life-years. When the costs and effects for subgroups are combined using standard decision analytic aggregation methods, the ACCG scenario is cost-saving and more effective.

CONCLUSION

The ACCG scenario is likely to reduce costs and increase life-years compared to the PCP scenario in many subgroups. If the estimated trade-offs between the subgroups in terms of outcomes and costs are acceptable to decision-makers, then widespread implementation of the ACCG scenario is expected to reduce overall costs and be accompanied by positive outcomes overall.

Evaluating waiting time effect on health outcomes at admission: a prospective randomized study on patients with osteoarthritis of the knee joint

AIMS

To evaluate the effect of waiting on health-related quality of life (HRQoL), pain and physical function in patients awaiting primary total knee replacement (TKR) due to osteoarthritis.

METHODS

Some 438 patients awaiting TKR were randomized to a short waiting time (WT) group (< or =3 months) or a non-fixed WT group. In the final assessment, 310 patients (213 women) with a mean age of 68 years were included. HRQoL was measured on being placed on the waiting list and again at hospital admission using the generic 15D. Patients' self-report pain and physical function were evaluated using a scale modified from the Knee Society Clinical Rating System.

RESULTS

The median WTs for patients with short and non-fixed WT were 73 days (range 8-600 days) and 266 days (range 28-818 days), respectively. At admission, as assessed by the intention-to-treat analysis, there were no statistically significant differences between the groups in the 15D total score and disease-specific pain and function.

CONCLUSIONS

Our study showed that longer WT did not result in worse pre-operative HRQoL.

Health and social service use among old people in the last 2 years of life

This study focuses on differences in health and social service use in the last 2 years of life among Finnish people aged 70-79, 80-89, and 90 or older and on the variation in service use in the various municipalities. The data set, derived from multiple national registers, consists of 75,578 people who died in 1998-2001. The services included hospitals and long-term-care facilities, use of regular home care, and prescribed medicines. General hospital and public long-term care were the services most commonly used: general hospitals for younger age groups and public long-term care for older groups. The number of inpatient days in hospital was lower with increasing age, but older age groups used long-term care more frequently. Men had more hospital inpatient days than women, but women used more long-term care. The number of hospital inpatient days increased rapidly in the last months of life, almost doubling in the final month. Days in public long-term care increased regularly in the last 2 years of life. Variation in both hospital and long-term care by municipality was remarkable. The results indicate that, among people aged 70 years and older, age is a major determinant of care in the last 2 years of life. The variation in the use of care by municipality and the differences between men and women deserve more detailed analysis in future.

The effects of integrated home care and discharge practice on functional ability and health-related quality of life: a cluster-randomised trial among home care patients

Objectives

The aim was to evaluate the effects of integrated home care and discharge practice on the functional ability (FA) and health-related quality of life (HRQoL) of home care patients.

Methods

A cluster randomised trial (CRT) with Finnish municipalities (n=22) as the units of randomisation. At baseline the sample included 669 patients aged 65 years or over. Data consisted of interviews (at discharge, and at 3-week and 6-month follow-up), medical records and care registers. The intervention was a generic prototype of care/case management-practice (IHCaD-practice) that was tailored to municipalities needs. The aim of the intervention was to standardize practices and make written agreements between hospitals and home care administrations, and also within home care and to name a care/case manager pair for each home care patient. The main outcomes were HRQoL—as measured by a combination of the Nottingham Health Profile (NHP) and the EQ-5D instrument for measuring health status—and also Activities of Daily Living (ADL). All analyses were based on intention-to-treat.

Results

At baseline over half of the patient population perceived their FA and HRQoL as poor. At the 6-month follow-up there were no improvements in FA or in EQ-5D scores, and no differences between groups. In energy, sleep, and pain the NHP improved significantly in both groups at the 3-week and at 6-month follow-up with no differences between groups. In the 3-week follow-up, physical mobility was higher in the trial group.

Conclusions

Although the effects of the new practice did not improve the patients' FA and HRQoL, except for physical mobility at the 3-week follow-up, the workers thought that the intervention worked in practice. The intervention standardised practices and helped to integrate services. The intervention was focused on staff activities and through the changed activities also had an effect on patients. It takes many years to achieve permanent changes in every worker's individual practice and it is also likely that changes in working practices would be visible before effects on patients. The use of other outcome measures, such as the use of services, may be clearer in showing a positive impact of the intervention rather than FA or HRQoL.

The effect of co-morbidities on health-related quality of life in patients placed on the waiting list for total joint replacement

Background

Co-morbidity is a powerful predictor of health care outcomes and costs, as well as an important cofounder in epidemiologic studies. The effect of co-morbidities is generally related to mortality or complications. This study evaluated the association between co-morbidity and health-related quality of life (HRQoL) in patients awaiting total joint replacement.

Methods

A total of 893 patients were recruited to the study between August 2002 and November 2003 in four Finnish hospitals. The effect of co-morbidity on HRQoL was measured by the generic 15D instrument and by a Visual Analog Scale (VAS). Comparative variance analysis of socio-demographic and clinical characteristics was described by using either an independent samples t-test or the Chi-square test. The differences in each of the 15D dimensions and the overall 15D single index score for patients were calculated. Two-sided p-values were calculated with the Levene Test for Equality of Variances.

Results

Patients with co-morbidity totaled 649; the incidence of co-morbidity was 73%. The mean number of co-morbidities among the patients was two. At baseline the 15D score in patients with and without co-morbidity was 0.778 vs 0.816, respectively. The difference of the score (0.038) was clinically and statistically significant (P < 0.001). The patients' scores with and without co-morbidity on the different 15D dimensions related to osteoarthritis-moving, sleeping, usual activities, discomfort and symptoms, vitality and sexual activity–were low in both groups. Patients with co-morbidity scored lower on the dimensions of moving, vitality and sexual activity compared to the patients without co-morbidity. Co-morbidity was significantly associated with a reduced HRQoL. Patients without co-morbidity had poorer VAS, arthritis had strong effect to their quality of life compared to the patients with co-morbidity.

Conclusion

Assessing co-morbidity in patients placed on the waiting list for joint replacement may be useful method to prioritization in medical decision-making for healthcare delivery. The assessment of co-morbidities during waiting time is important as well as evaluating how the co-morbidity may affect the final outcomes of the total joint replacement.

Alternative strategies to evaluate the cost-effectiveness of peritoneal dialysis and hemodialysis

BACKGROUND

Dialysis treatment requires considerable resources and it is important to improve the efficiency of care.

METHODS

Files of all adult end-stage renal disease (ESRD) patients who entered dialysis therapy between 1991 and 1996, were studied and all use of health care resources was recorded. A total of 138 patients started with in-center hemodialysis (HD) and 76 patients with continuous ambulatory peritoneal dialysis (CAPD). Four alternative perspectives were applied to assess effectiveness. An additional analysis of 68 matched CAPD-HD pairs with similar characteristics was completed.

RESULTS

Cost-effectiveness ratios (CER; cost per life-year gained) were different in alternative observation strategies. If modality changes and cadaveric transplantations were ignored, annual first three years' CERs varied between $41220-61465 on CAPD and $44540-85688 on HD. If CAPD-failure was considered as death, CERs were $34466-81197 on CAPD. When follow-up censored at transplantation but dialysis modality changes were ignored, CERs were $59409-95858 on CAPD and $70042-85546 on HD. If observation censored at any change of primarily selected modality, figures were $57731-66710 on CAPD and $74671-91942 on HD. There was a trend of lower costs and better survival on CAPD, the only exception was the strategy in which technical failure of modality was considered as death. Figures of the matched CAPD-HD pairs were very close to the figures of the entire study population.

CONCLUSIONS

Compared to HD, CERs were slightly lower on CAPD.

The role of job satisfaction, job dissatisfaction and demographic factors on physicians' intentions to switch work sector from public to private

This study is based on a unique data set for the years 1988-2003 and uses structural equation models to examine the impact of job satisfaction and job dissatisfaction on physicians' intention to switch from public- to private-sector work. In Finland, physicians who work primarily in a public-hospital or health-centre setting can also run a private practice. Therefore, we also analysed the impact of having a private practice on a physician's intention to change sector. We found that private practice had a positive, statistically significant effect on the intention to switch sector in 1998 and 2003. Results also suggest that job satisfaction decreases a physician's intention to switch sector, although for 1998 it had no effect. Surprisingly, job dissatisfaction significantly increased the physicians' intentions to leave the public sector only in the 1988 data.

Health-related quality of life in patients waiting for major joint replacement. A comparison between patients and population controls

Background

Several quality-of-life studies in patients awaiting major joint replacement have focused on the outcomes of surgery. Interest in examining patients on the elective waiting list has increased since the beginning of 2000. We assessed health-related quality of life (HRQoL) in patients waiting for total hip (THR) or knee (TKR) replacement in three Finnish hospitals, and compared patients' HRQoL with that of population controls.

Methods

A total of 133 patients awaiting major joint replacement due to osteoarthritis (OA) of the hip or knee joint were prospectively followed from the time the patient was placed on the waiting list to hospital admission. A sample of controls matched by age, gender, housing and home municipality was drawn from the computerised population register. HRQoL was measured by the generic 15D instrument. Differences between patients and the population controls were tested by the independent samples t-test and between the measurement points by the paired samples t-test. A linear regression model was used to explain the variance in the 15D score at admission.

Results

At baseline, 15D scores were significantly different between patients and the population controls. Compared with the population controls, patients were worse off on the dimensions of moving (P < 0.001), sleeping (P < 0.001), sexual activity (P < 0.001), vitality (P < 0.001), usual activities (P < 0.001) and discomfort and symptoms (P < 0.001). Further, psychological factors – depression (P < 0.001) and distress (P = 0.004) – were worse among patients than population controls. The patients showed statistically significantly improved average scores at admission on the dimensions of moving (P = 0.026), sleeping (P = 0.004) and discomfort and symptoms (P = 0.041), but not in the overall 15D score compared with the baseline. In patients, 15D score at baseline (P < 0.001) and body mass index (BMI) (P = 0.020) had an independent effect on patients' 15D score at hospital admission.

Conclusion

Although patients' HRQoL did not deteriorate while waiting, a consistently worse HRQoL was observed in patients waiting for major joint replacement compared with population controls.

Factors associated with physicians' choice of working sector: a national longitudinal survey in Finland

OBJECTIVE

To analyse factors affecting physicians' choice to work in either the public or the private sector.

METHOD

We undertook a longitudinal data analysis in the years 1988, 1993, 1998 and 2003 (n = 12 909) using a multilevel modelling technique. Factors related to economic factors, physician identity, appreciation as well as demographic factors were hypothesised to influence sector choice.

RESULTS

Physicians seem to make their career choices prior to graduation, at least to some extent. Wage levels, the physician's personal characteristics and whether or not the physician knew his or her place of work before graduation were the key factors affecting the decision-making process in the years 1988, 1993, 1998 and 2003. Physicians for whom wages were important were less likely to choose the public sector. Also, physicians who regarded themselves as entrepreneurial preferred to work in the private sector. If a physician had worked in the public sector during his or her medical training before graduation, the probability of applying for a vacancy in the public sector was higher.

CONCLUSION

It is not only economic factors, such as salary, that are involved in the physician's decision to choose the working sector.

A cost-effectiveness analysis of tension-free vaginal tape versus laparoscopic mesh colposuspension for primary female stress incontinence

BACKGROUND

Evaluation of cost-effectiveness of new surgical techniques is important. As the data on incontinence procedures are scarce, we evaluated the cost-effectiveness of tension-free vaginal tape procedure and laparoscopic mesh colposuspension as a primary surgical treatment for female stress urinary incontinence.

METHODS

In four university teaching hospitals and two central hospitals 128 stress incontinent women were randomized to tension-free vaginal tape procedure (n=70) or laparoscopic mesh colposuspension (n=51) in order to investigate the clinical performance of these two procedures. Primary objective clinical outcome measures were: stress test and 48-h pad test. Secondary subjective outcome measures were health-related quality of life measured in terms of visual analogue scale and Urinary Incontinence Severity Score. Alongside the clinical trial, a cost-effectiveness analysis for the main outcome measures was performed.

RESULTS

The changes in the 48-h pad test result did not reach statistical significance (p=0.105). When the visual analogue scale or Urinary Incontinence Severity Score are used as the outcome measure, the tension-free vaginal tape is more cost-effective than laparoscopic mesh colposuspension over a follow-up period of one year (p<0.000).

CONCLUSION

The clinical and economic data of the present study suggest that over a follow-up period of one year the tension-free vaginal tape procedure is more cost-effective than laparoscopic mesh colposuspension as a primary treatment for female stress urinary incontinence.

Cost-effectiveness of combined manipulation, stabilizing exercises, and physician consultation compared to physician consultation alone for chronic low back pain: a prospective randomized trial with 2-year follow-up

STUDY DESIGN

A prospective, randomized controlled trial.

OBJECTIVE

To examine long-term effects and costs of combined manipulative treatment, stabilizing exercises, and physician consultation compared with physician consultation alone for chronic low back pain (cLBP).

SUMMARY OF BACKGROUND DATA

An obvious gap exists in knowledge concerning long-term efficacy and cost-effectiveness of manipulative treatment methods.

METHODS

Of 204 patients with cLBP whose Oswestry Disability Index (ODI) was at least 16%, 102 were randomized into a combined manipulative treatment, exercise, and physician consultation group (i.e., a combination group), and 102 to a consultation alone group. All patients were clinically examined, informed about their back pain, and encouraged to stay active and exercise according to specific instructions based on clinical evaluation. Treatment included 4 sessions of manual therapy and stabilizing exercises aimed at correcting the lumbopelvic rhythm. Questionnaires inquired about pain (visual analog scale (VAS)), disability (ODI), health-related quality of life (15D Quality of Life Instrument), satisfaction with care, and costs.

RESULTS

Significant improvement occurred in both groups on every self-rated outcome measurement. Within 2 years, the combination group showed only a slightly more significant reduction in VAS (P = 0.01, analysis of variance) but clearly higher patient satisfaction (P = 0.001, Pearson chi2) as compared to the consultation group. Incremental analysis showed that for combined group compared to consultation group, a one-point change in VAS scale cost $512.

CONCLUSIONS

Physician consultation alone was more cost-effective for both health care use and work absenteeism, and led to equal improvement in disability and health-related quality of life. It seems obvious that encouraging information and advice are major elements for the treatment of patients with cLBP.

A randomized trial among women with heavy menstruation -- impact of a decision aid on treatment outcomes and costs

OBJECTIVE

To evaluate the effects of a decision aid for menorrhagia on treatment outcomes and costs over a 12-month follow-up.

DESIGN

Randomized trial and pre-trial prospective cohort study.

SETTING AND PARTICIPANTS

Gynaecology outpatient clinics in 14 Finnish hospitals, 363 (randomized trial) plus 206 (cohort study) patients with menorrhagia.

INTERVENTION

A decision aid booklet explaining menorrhagia and treatment options, mailed to patients before their first clinic appointment.

MAIN OUTCOME MEASURES

Health related quality of life, psychological well-being, menstrual symptoms, satisfaction with treatment outcome, use and cost of health care services.

RESULTS

All study groups experienced overall improvement in health-related quality of life, anxiety, and psychosomatic and menstrual symptoms, but not in sexual life. Treatment in the intervention group was more active than in the control group, with more frequent course of medication and less undecided treatments. However, there were no marked disparities in health outcomes, satisfaction with treatment outcome and costs. Total costs (including productivity loss) per woman because of menorrhagia over the 12-month follow-up were 2760 and 3094 in the intervention and control group, respectively (P = 0.1). The pre-trial group also had a significantly lower rate of uterus saving surgery compared with the control group, but no difference in costs because of menorrhagia treatment.

CONCLUSION

Despite some differences in treatment courses, a decision aid for menorrhagia in booklet form did not increase the use of health services or treatment costs, nor had it impact on health outcomes or satisfaction with outcome of treatment.

Impact of patient information booklet on treatment decision--a randomized trial among women with heavy menstruation

OBJECTIVE

Does a patient information booklet influence treatment for menorrhagia?

DESIGN

Randomized trial and a pre-trial prospective cohort study.

SETTING

Gynaecology outpatient clinics in 14 Finnish hospitals.

PARTICIPANTS

A total of 363 (randomized trial) plus 206 (cohort study) patients with menorrhagia.

INTERVENTION

An information booklet about menorrhagia and treatment options, mailed before the first visit to the outpatient clinic.

MAIN OUTCOME MEASURES

Distribution of treatment modalities, knowledge about treatment options, satisfaction with communication with personnel and anxiety.

RESULTS

Treatment decision within 3 months was made more often in the intervention group than in the control group (96% and 89% respectively, P = 0.02). Oral medication was more frequently chosen, and newly introduced treatments (minor surgery, hormonal intrauterine system) were less frequently used in the intervention group (at 3-month follow-up 21% and 29%, respectively). The differences persisted at the 12-month follow-up. In the pre-trial group, new treatment methods were less frequently chosen and used than in the control group. Additional information did not increase the number of surgical procedures used, improve knowledge, or influence satisfaction or anxiety.

CONCLUSIONS

Additional information led to an increase in specific treatment decisions and changed the distribution of used treatments without increasing the number of surgical procedures. The study suggests that well-informed women adopting an active role may counteract physicians' emphasis on newly introduced treatments.

Fatal injuries in Finnish agriculture, 1988-2000

Agriculture is one of the most hazardous industries in Finland. The aim of this study was to describe and analyze fatal farm injuries in Finland in 1988 to 2000. The information regarding farm-related fatalities was collected by the Kuopio Regional Institute of Occupational Health. The material of this study consisted of all fatal injuries that occurred on a farm or away from a farm in the course of agricultural work. A total of 217 farm-related fatalities occurred in Finland between 1988 and 2000. Of these, 120 were tractor-related, and 97 were other fatal farm injuries. Most of the injuries involved middle-aged or older male farmers. The most typical fatalities with tractors were tractor overturns during driving on a road or working in a field. Other fatal farm incidents occurred mainly in construction work, animal husbandry, or forest work. Elderly farmers and children proved to be risk groups for fatal injuries.

Clinical outcomes and costs with the levonorgestrel-releasing intrauterine system or hysterectomy for treatment of menorrhagia: randomized trial 5-year follow-up

CONTEXT

Because menorrhagia is often a reason for seeking medical attention, it is important to consider outcomes and costs associated with alternative treatment modalities. Both the levonorgestrel-releasing intrauterine system (LNG-IUS) and hysterectomy have proven effective for treatment of menorrhagia but there are no long-term comparative studies measuring cost and quality of life.

OBJECTIVE

To compare outcomes, quality-of-life issues, and costs of the LNG-IUS vs hysterectomy in the treatment of menorrhagia.

DESIGN, SETTING, AND PARTICIPANTS

Randomized controlled trial conducted between October 1, 1994, and October 6, 2002, and enrolling 236 women (mean [SD] age, 43 [3.4] years) referred to 5 university hospitals in Finland for complaints of menorrhagia.

INTERVENTIONS

Participants were randomly assigned to treatment with the LNG-IUS (n = 119) or hysterectomy (n = 117) and were monitored for 5 years.

MAIN OUTCOME MEASURES

Health-related quality of life (HRQL) as measured by the 5-Dimensional EuroQol and the RAND 36-Item Short-Form Health Survey, other measures of psychosocial well-being (anxiety, depression, and sexual function), and costs.

RESULTS

After 5 years of follow-up, 232 women (99%) were analyzed for the primary outcomes. The 2 groups did not differ substantially in terms of HRQL or psychosocial well-being. Although 50 (42%) of the women assigned to the LNG-IUS group eventually underwent hysterectomy, the discounted direct and indirect costs in the LNG-IUS group (2817 dollars [95% confidence interval, 2222 dollars-3530 dollars] per participant) remained substantially lower than in the hysterectomy group (4660 dollars [95% confidence interval, 4014 dollars-5180 dollars]). Satisfaction with treatment was similar in both groups.

CONCLUSIONS

By providing improvement in HRQL at relatively low cost, the LNG-IUS may offer a wider availability of choices for the patient and may decrease costs due to interventions involving surgery.

Levonorgestrel-releasing intrauterine system or hysterectomy in the treatment of essential menorrhagia: predictors of outcome

Levonorgestrel-releasing intrauterine system (LNG-IUS) has been advocated as an effective alternative to hysterectomy in the treatment of menorrhagia. The outcome predictors have been poorly known. In this study the amount of menstrual blood loss (MBL) turned out to be the single most important outcome predictor of these treatments. However, the treatment with LNG-IUS seemed to be an appropriate alternative to hysterectomy for all women who perceived their MBL heavy.

A randomized trial of combined manipulation, stabilizing exercises, and physician consultation compared to physician consultation alone for chronic low back pain

STUDY DESIGN

A prospective randomized controlled trial.

OBJECTIVES

To examine the effectiveness of combined manipulative treatment, stabilizing exercises, and physician consultation compared with physician consultation alone for chronic low back pain.

SUMMARY OF BACKGROUND DATA

Strong evidence exists that manual therapy provides more effective short-term pain relief than does placebo treatment in the management of chronic low back pain. The evidence for long-term effect is lacking.

METHODS

Two hundred four chronic low back pain patients, whose Oswestry disability index was at least 16%, were randomly assigned to either a manipulative-treatment group or a consultation group. All were clinically examined, informed about their back pain, provided with an educational booklet, and were given specific instructions based on the clinical evaluation. The treatment included four sessions of manipulation and stabilizing exercises aiming to correct the lumbopelvic rhythm. Questionnaires inquired about pain intensity, self-rated disability, mental depression, health-related quality of life, health care costs, and production costs.

RESULTS

At the baseline, the groups were comparable, except for the percentage of employees (P = 0.01). At the 5- and 12-month follow-ups, the manipulative-treatment group showed more significant reductions in pain intensity (P < 0.001) and in self-rated disability (P = 0.002) than the consultation group. However, we detected no significant difference between the groups in health-related quality of life or in costs.

CONCLUSIONS

The manipulative treatment with stabilizing exercises was more effective in reducing pain intensity and disability than the physician consultation alone. The present study showed that short, specific treatment programs with proper patient information may alter the course of chronic low back pain.

Factors predicting choice of treatment for menorrhagia in gynaecology outpatient clinics

The aim of this prospective study was to investigate factors predicting choice of treatment for excessive menstrual bleeding, with special emphasis on women's pre-treatment preference. A cohort of women with heavy menstruation and their treatment process in gynaecology outpatient clinics were followed-up for 1yr. A total of 383 35-54-yr-old women attending 14 Finnish hospitals participated. They completed a questionnaire before their first outpatient clinic visit, and postal follow-ups were conducted 3 and 12 months later. Information on treatment(s) during the follow-up was taken from medical records and questionnaires. The choice between hysterectomy and conservative treatments, and fulfillment of pre-treatment preference were the main outcome measures. During the 1-yr follow-up, 51% (n=196) of the women underwent hysterectomy and nine were still awaiting it, 12% (n=44) had a minor surgical procedure, 11% (n=41) had oral medication, 9% (n=33) used a hormonal intrauterine system, and nine women changed preventive method. Forty-two women (11%) reported having had no treatment. Data on previous treatments suggested that conservative treatment modalities were under-used. Most of the treatment decisions were made within the first 3-month period. Women's pre-treatment preference was the strongest predictor of chosen treatment. Unemployment, irregular periods and anxiety decreased the probability of a decision for hysterectomy, while pelvic pain and inconvenience due to bleeding increased it. The treatment plan accorded with pre-treatment preference in 72% of the women preferring hysterectomy and in 74% of those preferring a conservative option.

Mini-intervention for subacute low back pain: a randomized controlled trial

STUDY DESIGN

Randomized controlled trial.

OBJECTIVES

To investigate the effectiveness and costs of a mini-intervention, provided in addition to the usual care, and the incremental effect of a work site visit for patients with subacute disabling low back pain.

SUMMARY OF BACKGROUND DATA

There is lack of data on cost-effectiveness of brief interventions for patients with prolonged low back pain.

METHODS

A total of 164 patients with subacute low back pain were randomized to a mini-intervention group (A), a work site visit group (B), or a usual care group (C). Groups A (n = 56) and B (n = 51) underwent one assessment by a physician plus a physiotherapist. Group B received a work site visit in addition. Group C served as controls (n = 57) and was treated in municipal primary health care. All patients received a leaflet on back pain. Pain, disability, specific and generic health-related quality of life, satisfaction with care, days on sick leave, and use and costs of health care consumption were measured at 3-, 6-, and 12-month follow-ups.

RESULTS

During follow-up, fewer subjects had daily pain in Groups A and B than in Group C (Group A Group C, = 0.002; Group B Group C, = 0.030). In Group A, pain was less bothersome (Group A Group C, = 0.032) and interfered less with daily life (Group A Group C, = 0.040) than among controls. Average days on sick leave were 19 in Group A, 28 in Group B, and 41 in Group C (Group A Group C, = 0.019). Treatment satisfaction was better in the intervention groups than among the controls, and costs were lowest in the mini-intervention group.

CONCLUSIONS

Mini-intervention reduced daily back pain symptoms and sickness absence, improved adaptation to pain and patient satisfaction among patients with subacute low back pain, without increasing health care costs. A work site visit did not increase effectiveness.

Correlates of women's preferences for treatment of heavy menstrual bleeding

This cross-sectional survey investigated factors associated with treatment preferences of women with menorrhagia. Women (n = 474) aged 35-54 years referred to gynaecology out-patient clinics for menorrhagia were mailed a self-administered questionnaire before their first clinic visit. The main outcome measure was treatment preference. Hysterectomy and conservative treatment (combined with no treatment) were favoured equally often. In a multivariate analysis, completed family size (P = 0.003), menstrual pain (P = 0.02), irregular periods (P = 0.03), and higher age (P = 0.04) predicted hysterectomy preference, as did lower education level (P = 0.001), gynaecologist consultations (P = 0.002), and unemployment (P = 0.03). The psychological factors assessed were not associated with treatment preference. In conclusion, rational considerations regarding stage of reproductive life and severity of symptoms were linked to women's treatment preferences. However, education, employment status and use of specialists' services guided women's preferences even more powerfully than menstrual symptoms and burden caused by them. Doctors should pay more attention to motivating women for a trial of conservative treatment since only half of the women reported previous treatment for their menstrual problem.

Ways of coping with asthma in everyday life: validation of the Asthma Specific Coping Scale

OBJECTIVE

This study examines the validity of the Asthma Specific Coping Scale.

METHODS

Study samples were comprised of persons with drug-treated asthma (n=3464) drawn from the Drug Reimbursement Registry and asthma rehabilitation participants [brief (n=278) and comprehensive (n=316) intervention]. Data were collected by questionnaires.

RESULTS

The expected structure of the six subscales (restricted lifestyle, hiding asthma, positive reappraisal, information seeking, ignoring asthma, and asthma worry) was supported. The Cronbach's alpha reliabilities of the subscales ranged from .63 to .84. Concurrent validity was supported by meaningful correlations between asthma coping scales and psychosocial resources, health-related quality of life, and general coping. The asthma coping scales discriminated between the intervention participants and the population-based sample. Four out of six subscales also showed sensitivity to change after rehabilitation.

CONCLUSION

Though further longitudinal studies are needed, this scale seems to be a promising instrument to be used in surveys and outcome studies.

Cost-effectiveness of screening for familial abdominal aortic aneurysms

BACKGROUND

Screening for familial abdominal aortic aneurysms (AAA) is widely recommended. To analyze cost-effectiveness of screening for familial AAAs incremental cost-effectiveness (C/E) analysis based on an ultrasound screening among relatives and a decision model of screening program was compared to a baseline situation without systematic screening.

PATIENTS AND METHODS

74% (238/322) of first-degree relatives of 150 consecutive AAA patients were screened at HUCH (Helsinki University Central Hospital). Effectiveness and costs of treatment were assessed using the Finnish Hospital Discharge Register and from survival analysis of 1130 AAA patients who underwent elective or emergency surgery in HUCH. To form incremental C/E-ratios the existing clinical practice was compared to a screening program for male siblings. Hypothetical screened and control cohorts of 1000 male relatives were used to create the decision model. Parameters in C/E-analyses were derived from our own data except for growth and rupture rates. A sensitivity analysis was carried out.

RESULTS

The incremental effectiveness in life-years gained by the screening of male siblings was 92 years with incremental C/E-ratio of FIM 33,000 ($6200). According to sensitivity analysis the C/E-ratios were robust for all variables tested.

CONCLUSIONS

Screening of male siblings of AAA patients produces incremental life-years at low cost thus screening of male siblings is highly recommended.

Cardiac parasympathetic activity is increased by weight loss in healthy obese women

OBJECTIVE

We studied the effect of weight reduction on cardiac parasympathetic activity (PSA) in obese women. We also studied the relationship between the changes of PSA, resting energy expenditure (REE), and major cardiovascular risk factors.

RESEARCH METHODS AND PROCEDURES

Changes of cardiac vagal tone, an index of PSA, REE, and major cardiovascular risk factors, were measured in 52 healthy obese women after a 6-month weight reduction. Ten of the women were remeasured at 12 and 24 months. Cardiac vagal tone was assessed by a vagal tone monitor and REE by indirect calorimeter.

RESULTS

Cardiac vagal tone increased significantly (p = 0.046), averaging a 9.5% weight loss in 6 months. The vagal tone increased further with weight loss during the following 6 months, and thereafter, it declined with weight regain. The increase of cardiac vagal tone correlated significantly with decreases of body weight, fat mass, waist circumference, serum insulin, and heart rate. REE adjusted for fat-free mass and age did not change with weight loss and was not related to cardiac vagal tone at any time-point.

DISCUSSION

Cardiac PSA activity increases with weight loss in obese women. This increase may not be maintained long-term if body weight is regained. The rise of cardiac PSA is correlated with decreases of body fat mass, abdominal fat, serum insulin, and heart rate. Cardiac PSA is not related to REE.

Weight change and blood coagulability and fibrinolysis in healthy obese women

OBJECTIVES

To study the effect of weight loss and subsequent weight maintenance or weight regain on the activities of FVII and plasminogen activator inhibitor 1 (PAI-1) and the concentration of fibrinogen over 12 months in obese women consuming a hypoenergetic, low-fat diet with or without orlistat. In addition, the relation between the changes of the activities of PAI-1 and FVII with the changes of other cardiovascular risk factors were examined.

METHODS AND PROCEDURES

Design-a 12-month randomized double-blind weight reduction trial of placebo and orlistat. Subjects-51 healthy obese women (age 44+/-0.7 y, BMI 36.2+/-0.5 kg/m(2), mean+/-s.e.m.) Treatment-the participants were on a hypoenergetic diet (-600 kcal daily). The diet was adjusted for actual body weight (-300 kcal) at 6 months. Women were randomized to receive either orlistat 120 mg three times daily (n=25) or placebo three times daily (n=26) for 12 months according to a double-blind protocol after a 1 month run-in period. Measurements-changes of body weight, body composition, haemostatic and other cardiovascular risk factors were measured at 3-6 month intervals. The activity of plasma PAI-1 was measured by a chromogenic method, fibrinogen by the PT-derived method and the activity of FVII by the one-stage method.

RESULTS

The changes in body weight between orlistat and placebo groups were not statistically significantly different. Orlistat did not influence haemostatic factors beyond its effect on weight loss. Therefore, the results of the orlistat and placebo groups were pooled. The average weight loss at 3, 6 and 12 months was 7.6, 9.5 and 10.0 kg, respectively (P<0.001). Between 6 and 12 months, 35% of women regained weight, 24% had stable weight and 41% continued to lose weight. No changes in the mean plasma fibrinogen concentration were observed at any time point during the trial. During the first 3 months the activities of PAI-1 and FVII decreased. The decline depended on the magnitude of weight loss. Between months 6 and 12 the changes of PAI-1 and FVII activities paralleled the changes of body weight. The activities rose with weight rebound but remained below the 6-month values if weight loss was sustained or continued. The changes of serum insulin were significantly correlated with the changes of both PAI-1 and FVII at 6 months and with PAI-1 at 12 months.

CONCLUSIONS

The maintenance of modest weight loss is associated with long-term benefits in PAI-1 and FVII in obese women. The change of serum insulin is associated with the changes of PAI-1 activities. Fibrinogen is not affected by modest weight loss.

Quality of life and cost-effectiveness of levonorgestrel-releasing intrauterine system versus hysterectomy for treatment of menorrhagia: a randomised trial

BACKGROUND

Heavy menstrual blood loss is a common reason for women to seek medical care. The levonorgestrel-releasing intrauterine system (IUS) is an effective medical treatment for menorrhagia. We report a randomised comparison of this approach with hysterectomy in terms of the quality of life of women with menorrhagia and cost-effectiveness.

METHODS

Of 598 women referred with menorrhagia to five university hospitals in Finland, 236 were eligible and agreed to take part. They were randomly assigned treatment with the levonorgestrel-releasing IUS (n=119) or hysterectomy (n=117). The amount of menstrual blood loss was objectively measured. The primary outcome measure was health-related quality of life at 12-month follow-up. Analyses were by intention to treat.

FINDINGS

In the group assigned the levonorgestrel-releasing IUS, 24 (20%) women had had hysterectomy and 81 (68%) continued to use the system at 12 months. Of the women assigned to the hysterectomy group, 107 underwent the operation. Health-related quality of life improved significantly in both the IUS and hysterectomy groups (change 0.10 [95% CI 0.06-0.14] in both groups) as did other indices of psychological wellbeing. There were no significant differences between the treatment groups except that women with hysterectomy suffered less pain. Overall costs were about three times higher for the hysterectomy group than for the IUS group.

INTERPRETATION

The significant improvement in health-related quality of life highlights the importance of treating menorrhagia. During the first year the levonorgestrel-releasing IUS was a cost-effective alternative to hysterectomy in treatment of this disorder.

Effect of orlistat treatment on body composition and resting energy expenditure during a two-year weight-reduction programme in obese Finns

OBJECTIVE

To examine the effect of orlistat (Xenical) treatment on body composition and resting energy expenditure (REE) during a 2 y weight-reduction programme in obese Finns.

SUBJECTS

Of initially 96 obese subjects who participated in the weight-reduction programme, those 72 subjects (13 men, 59 women, body mass index (BMI) 35.9 +/- 3.9 kg/m2, age 43.4 +/- 6.0 y, mean +/- s.d.) with the complete set of data for 2 y were included in the study.

DESIGN

After a 4-week lead-in period, subjects were randomized with either orlistat 120 mg t.i.d. or placebo t.i.d. in conjunction with a mildly hypoenergetic balanced diet for 1 y. This was followed by 1 y double-blind period with the subjects within each treatment group re-assigned to receive orlistat 120 mg t.i.d. or placebo t.i.d. in conjunction with a weight maintenance diet.

MEASUREMENTS

Body composition and REE were measured after an overnight fast by a bioelectrical impedance method and indirect calorimeter, respectively. The measurements were performed at the beginning and at 3, 6, 12 and 24 months.

RESULTS

During the first year, the orlistat-treated group had greater reduction of body weight and fat mass but not of fat-free mass or REE as compared to placebo. During the second year, orlistat treatment was associated with smaller regain of body weight and fat mass with no significant differences in the changes of fat-free mass or REE as compared to placebo.

CONCLUSION

In addition to better weight loss and maintenance of reduced weight, orlistat treatment is associated with beneficial changes in body composition but with no excess decrease in resting energy expenditure as compared to that achieved during placebo with a dietary therapy alone.

Do QOL instruments agree? A comparison of the 15D (Health-Related Quality of Life) and NHP (Nottingham Health Profile) in hip and knee replacements

OBJECTIVES

Several instruments for measuring health-related quality of life (HRQOL) have been developed, and others are under construction. The problem is whether the different HRQOL measures show comparable results. We first compared the functional relationship of the Nottingham Health Profile (NHP) and the 15-dimensional measure of HRQOL (15D) in hip and knee replacement patients. The hypothesis was that condition or intervention does not affect the functional relationship between NHP and 15D changes.

METHODS

We assessed the agreement of the instruments by comparing observed changes in the 15D and its fitted values derived by regressing the 15D by the NHP dimensions. Patients (n = 452) were recruited consecutively from seven Finnish orthopedic departments during April 1991-May 1992. HRQOL was measured prior to surgery and 6, 12, and 24 months postoperatively.

RESULTS

There was a different functional relationship between the HRQOL instruments in hip and knee patients; they agreed upon the direction of changes in HRQOL in 84% and showed opposite signs in 12%. The NHP showed significantly more improvement in quality of life than the 15D.

CONCLUSIONS

The two instruments were in slight but significant disagreement. Estimates of effectiveness can vary according to the instrument used. Comparisons of effectiveness in healthcare programs measured by differing instruments need information on the functional discrepancies between the instruments in the conditions and interventions in which they are applied.

Cost-effectiveness of targeted screening for abdominal aortic aneurysm. Monte Carlo-based estimates

OBJECTIVES

This article reports a cost-effectiveness analysis of targeted screening for abdominal aortic aneurysm (AAA). A major emphasis was on the estimation of distributions of costs and effectiveness.

METHODS

We performed a Monte Carlo simulation using C programming language in a PC environment. Data on survival and costs, and a majority of screening probabilities, were from our own empirical studies. Natural history data were based on the literature.

RESULTS

Each screened male gained 0.07 life-years at an incremental cost of FIM 3,300. The expected values differed from zero very significantly. For females, expected gains were 0.02 life-years at an incremental cost of FIM 1,100, which was not statistically significant. Cost-effectiveness ratios and their 95% confidence intervals were FIM 48,000 (27,000-121,000) and 54,000 (22,000-infinity) for males and females, respectively. Sensitivity analysis revealed that the results for males were stable. Individual variation in life-year gains was high.

CONCLUSIONS

Males seemed to benefit from targeted AAA screening, and the results were stable. As far as the cost-effectiveness ratio is considered acceptable, screening for males seemed to be justified. However, our assumptions about growth and rupture behavior of AAAs might be improved with further clinical and epidemiological studies. As a point estimate, females benefited in a similar manner, but the results were not statistically significant. The evidence of this study did not justify screening of females.

Reoperations after lumbar disc surgery: a population-based study of regional and interspecialty variations

STUDY DESIGN

A follow-up study using nationwide administrative databases.

OBJECTIVES

To explore rates of reoperation after lumbar disc surgery and their regional and interspecialty variations.

SUMMARY OF BACKGROUND DATA

In many Western countries, rates of lumbar disc surgery display significant geographic variations suggesting varying treatment criteria among operating surgeons. Few population-based studies have explored the risk of reoperation after disc surgery, and regional or interspecialty variations in the reoperations are unknown.

METHODS

Patients who underwent lumbar spine surgery from January 1, 1987 through December 31, 1995, were identified in the Finnish Hospital Discharge Register. Data on the patients' initial disc operations, subsequent operations, and cause-of-death records were linked using personal identification codes. The Kaplan-Meier method and proportional hazard model were used to analyze risks of reoperation after initial surgery, according to hospital catchment area rates of disc surgery and for neurosurgical and orthopedic patients of university hospitals.

RESULTS

12.3% of 25,359 surgical patients with herniated lumbar discs underwent subsequent lumbar operations corresponding to the cumulative risk of 18.9% in the 9-year follow-up. Reoperation rates increased during the study period with the recent patient cohorts exhibiting risks. The reoperation risk showed a systematic geographic variation: the higher the regional disc surgery rate, the higher the reoperation risk. Overall, neurosurgical patients had a higher reoperation risk than orthopedic patients (relative risk [RR]: 1.57, 95% confidence interval [CI]: 1.17-2.10), but this was not a uniform finding.

CONCLUSIONS

The reoperation risk after disc surgery increased during the study period and was higher in hospital catchment areas with higher overall discectomy rates. The reoperation risks varied among the university hospitals but tended to be higher for neurosurgical rather than for orthopedic patients.

Priority-setting in Finnish healthcare

The characteristics which affect priority setting in the Finnish healthcare system include strong municipal (local) administration, no clear separation between producers and purchasers, a duality in funding, and the potential for physicians in public hospitals to practice in the private sector. This system has its strengths, such as the possibility to effectively co-ordinate social and healthcare services, and a strong incentive to take care of local needs, because of municipal responsibility to finance these services largely through local taxes. However, the municipalities are typically too small to take advantage of these potentials, their knowledge is scarce especially of secondary care and their negotiating power with respect to hospitals is low. Local politicians also have a dual role: they represent the needs of the local population but simultaneously they are decision-makers in hospitals. Full-time physicians are allowed to act in a dual role as well; they can run a private practice, which is paid for on a fee-for-service basis, while the hospital pays (mostly) a fixed monthly salary. The share of financing which flows from the National Sickness Insurance system to healthcare users may have adverse effects on the local use of resources. The broad national consensus statement on patient-level priorities did not reach any general rules on priorities. Strong support was given to citizens' equal right to access all healthcare services. In healthcare practice, this general rule has some exemptions. First, the reimbursement schemes for prescribed drugs vary depending on the severity and chronic nature of the disease. Secondly, the tax-financed dental services for the young are clearly prioritised over those of older citizens. In the consensus statement, emphasis was put on improving the efficiency of producing health services in order to avoid having to impose patient-level priorities.

Quality of life after prolonged intensive care

OBJECTIVE

To assess the subjective health status, quality of life, and functional ability of patients whose intensive care stay was prolonged and to compare their quality of life with that of the general population.

DESIGN

Inception cohort study.

SETTING

Twenty-three-bed multidisciplinary intensive care unit (ICU) in a tertiary care center.

PATIENTS

A consecutive sample of 718 patients aged > or = 18 yrs who required intensive care > or = 4 days.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

The Nottingham Health Profile was used to compare the ICU patients with a random sample (n = 2,595) of the general population. The quality of life and functional ability of 368 respondents (78.3% of 470 survivors) were assessed at 6 months after ICU admission. The length of the ICU stay was 13.6+/-11.8 (median, 9; maximum, 81) days. The quality of life and its various dimensions were influenced by the diagnosis for ICU admission and age. Although problems in physical mobility and energy were prevalent among all patient groups, only a small proportion was dependent on others for the management of daily activities. Patients with trauma or respiratory failure experienced the most limitations. The quality of life of elderly patients and patients who had undergone cardiac surgery was comparable with the general population regarding emotional reactions, social isolation, and pain.

CONCLUSIONS

The quality of life of survivors after a prolonged intensive care stay is fairly good, although not comparable with that of the general population. The psychosocial aspects of the quality of life are restored more rapidly than physical performance.

Effect of weight loss and regional fat distribution on plasma leptin concentration in obese women

OBJECTIVES

To investigate how circulating leptin concentrations are related to regional fat distribution and whether moderate weight loss alters these relationships.

DESIGN

A 6 month, clinical weight reduction trial with measurements before and after weight loss.

SUBJECTS

38 healthy, obese women (age: 44.3+/-9.9 y, BMI: 34.0+/-4.0 kg/m2).

MEASUREMENTS

The following measurements were made. 1. indices of obesity and fat distribution: weight, body mass index (BMI), hip circumference (peripheral fat), waist circumference, total body fat (bioelectrical impedance), abdominal fat distribution: visceral fat and abdominal subcutaneous fat (ultrasonography); and 2. Biochemical measurements: plasma leptin and serum insulin.

RESULTS

Baseline plasma leptin concentrations were three-fold higher in obese women than in normal weight controls. After weight loss averaging 8.4 kg (9.0%), plasma leptin decreased by a mean of 22.3% (P < 0.001), corresponding to body fat decrease of 16.6% (P < 0.001), abdominal subcutaneous fat decrease of 17.4% (P < 0.001) and visceral fat decrease of 18.7% (P < 0.001). The total amount of body fat correlated with plasma (serum) leptin before (r = 0.64, P < 0.001) and after (r = 0.75, P < 0.001) weight loss. Plasma leptin concentrations expressed per kg of body fat did not change significantly during weight loss. After controlling for body fat, baseline leptin concentrations were significantly associated with hip circumference (r = 0.57, P < 0.001) but not with any indices of abdominal fat distribution. After weight loss the associations became significant for hip and waist circumference as well as for visceral and abdominal subcutaneous fat. Changes in leptin correlated with changes in all indices of obesity except visceral fat.

CONCLUSIONS

Plasma leptin concentrations reflect not only total fat mass but also adipose tissue distribution, especially peripheral fat. Plasma leptin values per kilogram of fat mass do not change significantly with modest weight loss.

Costs and cost-effectiveness in hip and knee replacements. A prospective study

The extensive benefits of the total hip (THA) and knee (TKA) replacements are well documented, but surprisingly little is known about their economics. We assessed costs, cost-effectiveness (C/E), and patient-related C/E variances in THA and TKA from data on 276 THA and 176 TKA patients. Patients with primary arthrosis, primary operation, and total joint replacement were recruited from seven hospitals between March 1991 and June 1992. Their use of health and other welfare services together with health-related quality of life (HRQoL) were measured before the surgery and at 6, 12, and 24 months postoperatively. HRQoL was assessed by the 15D, a 15-dimensional HRQoL instrument, and the Nottingham Health Profile. Costs were assessed from questionnaire responses, the Finnish Hospital Discharge Register, and Finnish Arthroplasty Register. Total hospital costs per patient were 45,000 FIM (US $10,500) for THA and 49,600 FIM (US $11,500) for TKA. Prosthesis costs comprised 21% of these costs in THA and 24% in TKA. On average, hip patients gained more in terms of HRQoL, and the operations were more cost-effective. The C/E ratio for younger (< or = 60 years) knee patients did not differ from those in all age groups of hip patients, whereas TKAs in those over 60 years had a worse C/E ratio compared with all other patient subgroups. It was concluded that allocation efficiency can be improved by considering not only the intervention but also patient characteristics such as age. Indeed, the C/E ratio varied more across age groups of knee patients than between average THA and TKA patients.

Relationship of metabolic variables to abdominal adiposity measured by different anthropometric measurements and dual-energy X-ray absorptiometry in obese middle-aged women

OBJECTIVES

To investigate how abdominal adiposity assessed by different anthropometric measurements and dual-energy X-ray absorptiometry measurements is associated with metabolic risk factors for cardiovascular disease and non-insulin-dependent diabetes mellitus in obese women.

DESIGN

Cross-sectional study.

SUBJECTS

Forty-three healthy, obese, middle-aged women (age: 29-64 y, BMI: 28-42 kg/m2).

MEASUREMENTS

(1) Anthropometry: waist circumference, waist-to-hip ratio, waist-to-height ratio, abdominal sagittal and transverse diameters and their ratio. (2) Dual-energy X-ray absorptiometry: the amount of total and regional abdominal fat. (3) Metabolic measurements: serum total, VLDL, LDL, HDL cholesterol, triglycerides, fasting and postglucose serum insulin and glucose.

RESULTS

After adjustment for age and BMI, all the anthropometric measurements except waist-to-hip ratio and waist-to-height ratio related significantly to HDL and LDL cholesterol. On the other hand, waist-to-hip ratio and waist-to-height ratio showed an association with triglycerides. In addition, all the anthropometric measurements except transverse diameter correlated significantly with fasting insulin and fasting glucose. Waist-to-hip ratio was the only measure that associated with 2 h glucose concentration. The differences between the correlation coefficients were not statistically significant in the z-transformed correlation coefficient test. As to dual-energy X-ray absorptiometry results, the region from the dome of diaphragm to the top of femur ('abdominal fat') and the area between the first and the fourth lumbal vertebrae ('upper lumbal fat') inversely related to HDL cholesterol and positively to triglycerides. Both of these regions correlated significantly with fasting insulin, and "upper lumbal fat' associated also with fasting glucose even after adjustment for age and BMI.

CONCLUSION

None of the anthropometric measurements (waist circumference, waist-to-hip ratio, waist-to-height ratio or sagittal diameter) was significantly superior to others to assess the metabolic risk profile. 'Upper lumbal fat' (the area between the first and the fourth lumbal vertebrae) measured by dual-energy X-ray absorptiometry discerned obese women with elevated fasting insulin and fasting glucose.

Haematological toxicity: a marker of adjuvant chemotherapy efficacy in stage II and III breast cancer

Two hundred and eleven patients with node-positive stage II and III breast cancer were treated with eight cycles of adjuvant chemotherapy comprising cyclophosphamide, doxorubicin and oral ftorafur (CAFt), with and without tamoxifen. All patients had undergone radical surgery, and 148 patients were treated with post-operative radiotherapy in two randomized studies. The impact of haematological toxicity of CAFt on distant disease-free (DDFS) and overall survival (OS) was recorded. Dose intensity of all given cycles (DI), dose intensity of the two initial cycles (DI2) and total dose (TD) were calculated separately for all chemotherapy drugs and were correlated with DDFS and OS. Patients with a lower leucocyte nadir during the chemotherapy had significantly better DDFS and OS (P = 0.01 and 0.04 respectively). Dose intensity of the two first cycles also correlated significantly with DDFS (P = 0.05) in univariate but not in multivariate analysis, while the leucocyte nadir retained its prognostic value. These results indicate that the leucocyte nadir during the adjuvant chemotherapy is a biological marker of chemotherapy efficacy; this presents the possibility of establishing an optimal dose intensity for each patient. The initial dose intensity of adjuvant chemotherapy also seems to be important in assuring the optimal effect of adjuvant chemotherapy.

Quality of life and functional ability in hip and knee replacements: a prospective study

The impact of hip (THA) and knee arthroplasty (TKA) on patients' health-related quality of life (HRQOL), physical ability and functioning was assessed in a two year follow-up study of 276 hip and 176 knee patients. The eligibility criteria were a diagnosis of primary arthrosis, a primary operation, and total joint arthroplasty. Patients were interviewed by questionnaire prior to the operation and 6, 12 and 24 months after the surgery. Subjective health outcomes were assessed with the Nottingham Health Profile and the 15D, a fifteen dimensional HRQOL measure. Patients' physical ability was assessed using measures of activities of daily living, and of physical mobility. Patient related outcome variations were analyzed by regression models. Major improvements were observed for pain, sleep and physical mobility. On average, in most of the quality of life dimensions the patients attained a similar quality of life as the comparable general population and only 4.7% of hip and 9.7% of knee patients had a worse HRQOL score at all three post-operative measurements than at baseline. Naturally, those with the poorest HRQOL pre-operatively gained most from the operation. High age did not lessen HRQOL gains from THA, but in TKA the oldest patients gained least in terms of 15D scores. Hip, but not knee patients with a long education tended to have greater improvements in quality of life and functional ability.

Hospital- and patient-related characteristics determining length of hospital stay for hip and knee replacements

Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are among the most prestigious health care technologies. Their popularity has grown rapidly, and an increasing proportion of health care resources is allocated to them. We studied patient- and hospital-related factors that cause variation in a major determinant of hospital costs, the length of hospital stay (LOS) for THA and TKA. We gathered data on 10,288 hip and 5,173 knee patients with primary or secondary arthrosis from the Finnish Arthroplasty Register, which we linked with the Finnish Hospital Discharge Register. Patient- and hospital-related variations in LOS were explained using regression models. Of the patient-related factors, complications caused the greatest prolongation of hospital stay, but patient's age, gender, and charge category also influenced LOS. Hospital-related factors were major causes of LOS variation. In the hospitals the average case-mix-adjusted LOS ranged from less than a week to 3 weeks. The number of arthroplasties performed in hospital was inversely related to LOS. The within-hospital LOS figures for THA and TKA were strikingly similar and persistent.

Vinorelbine and epirubicin in metastatic breast cancer. A dose finding study

The aim of the study was to define the maximum tolerated dose (MTD) of vinorelbine given as one or two weekly doses in combination with epirubicin 60 mg/m2 every third week. The MTD was defined as the dose resulting in a WHO grade III or IV leucopenia exceeding 50% of patients. Patients were treated in groups of 10 at escalating doses of vinorelbine. The number of patients at the final dose level was expanded to 20. The dose of epirubicin was kept constant at 60 mg/m2 every third week. At dose level 1, 15 mg/m2 vinorelbine was given on day 1 at level 2, 20 mg/m2 was given on day 1 and at level 3, 20 mg/m2 was given on days 1 and 8. The MTD was reached at dose level 3. WHO haematological toxicity grade IV occurred in 0, 10 and 45% and grade III at 60, 30 and 30% of patients at dose levels 1, 2 and 3, respectively. Despite the common occurrence of grade IV haematological toxicity, only two serious infections were noted. Non-haematological toxicity of vinorelbine included neurotoxicity, manifesting as muscle weakness, constipation and paresthesias in the majority of patients. Neurotoxicity was usually mild and did not require treatment discontinuation. Phlebitis at the injection site was troublesome in many patients. Alopecia and nausea, probably due to epirubicin, occurred in most patients. The response rates were 22% (95% CI (confidence interval) 3-60%), 40% (12-74%) and 60% (36-81%) at levels 1, 2 and 3, respectively (non-significant).

The prognosis of stage III breast cancer treated with postoperative radiotherapy and adriamycin-based chemotherapy with and without tamoxifen. Eight year follow-up results of a randomized trial

Sixty-one patients with primary node positive stage III breast cancers were randomized to receive postoperative radiotherapy and doxorubicin-based chemotherapy (eight cycles of CAFt: cyclophosphamide, adriamycin, oral ftorafur) with or without tamoxifen as adjuvant treatment. The five-year overall survival for all patients was 49% (with tamoxifen 48% and without tamoxifen 50%) and disease-free survival 33% (with tamoxifen 27% and without 39%). Local control for all patients was only 64% despite the postoperative radiotherapy. There was no significant difference between these two treatment groups in overall and disease-free survival or local control. The prognosis of stage III breast cancer remains grim despite modern adjuvant therapy. In addition to more effective systemic treatment more effective local therapy is also needed in order to obtain satisfactory local control. The most important studies in stage III breast cancer with 5-year survival results are reviewed here.

Health and quality of life before and after hip or knee arthroplasty

The impact of hip and knee arthroplasty based on the patients' own evaluations of their health, quality of life, and physical ability was assessed using a cross-sectional study design. The eligibility criteria were a diagnosis of primary arthrosis, primary operation, and total joint arthroplasty. Preoperative hip and knee patient groups were compared with similar groups who underwent arthroplasty 2 or 5 years previously. Subjective health outcome was assessed with the Nottingham health profile and a 15-dimensional, health-related quality of life measure. Patients' physical ability was assessed using a measure of activities of daily living. Major improvements were observed for pain, sleep, range of motion, and physical ability. However, after surgery, patients were less healthy than the general population of the same age. The health status of patients operated on 2 or 5 years ago was similar, suggesting that health gains persist for several years.

Salvage therapies in women who fail to respond to first-line treatment with fluorouracil, epirubicin, and cyclophosphamide for advanced breast cancer

PURPOSE

We studied all salvage therapies given until death or the end of follow-up evaluation in women who failed to respond to the same first-line cytotoxic therapy for metastatic breast cancer.

PATIENTS AND METHODS

The study cohort consisted of 140 women who had received the fluorouracil, epirubicin, and cyclophosphamide (FEC) regimen for metastatic breast cancer. Eight patients were excluded. No exclusions with respect to disease site, performance status, or biochemical abnormalities were made. The median follow-up time was 29 months for surviving patients.

RESULTS

Most patients (88%) died during the follow-up period. Patients received a median of three salvage therapies (range, zero to eight) during the course of disease. Most courses (52%) were not assessable for response. Fifty-percent of courses consisted of chemotherapy: 35% of hormonal and 15% of combination of cytotoxic and hormonal therapies. The median duration of therapy (DT) ranged from 4 to 1 months, and decreased with advancing stages of therapy. Similarly, median time to treatment failure (TTF) ranged from 3 to 0.5 months. For unknown causes, patients who received second-line hormonal therapy fared better than those who received other forms of therapy. Of 366 analyzed courses, only one complete response (CR) and 18 partial responses (PRs) were observed (response rate, 11% for assessable and 5% for all courses). Stable disease for at least 3 months was found in 20% to 25% of courses. Most responses (n = 10) occurred during first salvage therapy, and no responses were observed after third salvage therapy.

CONCLUSIONS

Response rates for salvage therapies were low, and median treatment times short. The value of offering more than two salvage chemotherapy regimens to an unselected group of patients is questionable.
