Parental intervention choices for children undergoing repeated surgeries.

UNLABELLED: No studies have examined parental preference for a preoperative intervention in healthy children undergoing subsequent surgeries. We collected data prospectively from 83 children who previously underwent surgery and were part of an investigation by our study group, then returned for a subsequent surgery. At the initial surgery, children were assigned (no parental intervention) to receive oral midazolam (n = 13), or parental presence during the induction of anesthesia (PPIA, n = 27), or PPIA + midazolam (n = 10) or no intervention (n = 33). At a subsequent surgery, parents chose the preoperative intervention. We found that >80% of all parents chose PPIA (with or without midazolam) at the subsequent surgery regardless of the intervention they received previously. Of parents whose children received PPIA at the initial surgery, 70% chose PPIA again. In contrast, only 23% of the patients who received midazolam at the initial surgery requested midazolam at the subsequent surgery and only 15% of the patients who received no intervention at the initial surgery requested no intervention at the subsequent surgery. All parents of very anxious children at the initial surgery chose some intervention at the subsequent surgery (P = 0.022). Parents of children who underwent a subsequent surgery preferred PPIA regardless of any previous intervention. Also, parents' intervention preferences at the subsequent surgery were influenced by children's anxiety at the initial surgery. IMPLICATIONS: Parents of children who undergo a subsequent surgery prefer to be present during the induction of anesthesia regardless of whether the child was medicated or had parents present or did not receive anything at the initial surgery. Also, parents' preference for medication or parental presence at the subsequent surgery was influenced by the child's anxiety at the initial surgery.

Effect on health-related outcomes of interventions to alter the interaction between patients and practitioners: a systematic review of trials.

PURPOSE: We wanted to identify published randomized trials of interventions to alter the interaction between patients and practitioners, develop taxonomies of the interventions and outcomes, and assess the evidence that such interventions improve patients' health and well-being. METHODS: Undertaking a systematic review of randomized trials, we sought trials in primary and secondary care with health-related outcomes, which we found by searching MEDLINE, HealthSTAR, and PsycINFO bibliographic databases through 1999. We also completed one round of manual citation searching. RESULTS: Thirty-five trials were included. Most were set in primary care in North America. Trials were heterogeneous in populations, settings, interventions, and measures. Interventions frequently combined several poorly described elements. Explicit theoretical underpinning was rare, and only one study linked intervention through process to outcome measures. Health outcomes were rarely measured objectively (6 of 35), and only 4 trials with health outcomes met predefined quality criteria. Interventions frequently altered the process of interactions (significantly in 73%, 22 of 30 trials). Principal outcomes favored the intervention group in 74% of trials (26 of 35), reaching statistical significance in 14 (40%). Positive effects on health outcomes achieved statistical significance in 44% of trials (11 of 25); negative effects were uncommon (5 of 25, 20%). Simple approaches to increasing the participation of patients in the clinical encounter, such as providing practitioners with a note from patients about their concerns beforehand, showed promise, as did more complex programs providing specific information about disease and attention to emotion. Apparently similar interventions varied in effectiveness across studies. CONCLUSIONS: Successful interactions between patients and their practitioners lie at the heart of medicine, yet there are few rigorous trials of well-specified interventions to inform best practice. Trial evidence suggests that a range of approaches can achieve changes in this interaction, and some show promise in improving patients' health. To advance knowledge further, we need to replicate promising studies using rigorous methods. These should include explicit theoretical frameworks designed to link effects on key communication and interaction characteristics through to effects on health outcomes.

Improving influenza vaccination rates of high-risk inner-city children over 2 intervention years.

PURPOSE: Influenza immunization rates among children with high-risk medical conditions are disappointingly low, and relatively few data are available on raising rates, particularly over 2 years. We wanted to determine whether interventions tailored to individual practice sites improve influenza immunization rates among high-risk children in inner-city health centers over 2 years. METHOD: A before-after trial to improve influenza immunization of children was conducted at 5 inner-city health centers (residencies and faith-based). Sites selected interventions from a menu (eg, standing orders, patient and clinician reminders, education) proved to increase vaccination rates, which were directed at children aged 2 to 17 years with high-risk medical conditions. Intervention influenza vaccination rates and 1 and 2 years were compared with those of the preintervention year (2001-2002) and of a comparison site. RESULTS: Influenza vaccination rates improved modestly from baseline (10.4%) to 13.1% during intervention year 1 and to 18.7% during intervention year 2 (P <.001), with rates reaching 31% in faith-based practices. Rates increased in all racial and age-groups and in Medicaid-insured children. The increase in rates was significantly greater in intervention health centers (8.3%) than in the comparison health center (0.7%; P <.001). In regression analyses that controlled for demographic factors, vaccination status was associated with intervention year 1 (odds ratio [OR], 1.9; 95% confidence interval [CI], 1.6-2.2) and with intervention year 2 (OR, 2.8; 95% CI, 2.3-3.4), as well as with practice type. Adolescents had lower vaccination rates than children 2 to 6 years old (OR, 0.6; 95% CI, 0.5-0.7). CONCLUSIONS: Tailored interventions selected from a menu of interventions modestly increased influenza vaccination rates over 2 years at health centers serving children from low-income families. We recommend this strategy for faith-based practices and residencies with 1 practice site, but further research is needed on multisite practices and to achieve higher influenza vaccination rates.

An evaluation of the effectiveness of a peer sexual health intervention among secondary-school students in Zambia.

This study investigated whether there were any changes in knowledge and normative beliefs regarding abstinence and condoms and personal risk perception of acquiring HIV among Zambian secondary-school students who were exposed to a peer sexual health intervention. Schools were randomly assigned to intervention and control groups. A baseline assessment that measured knowledge, normative beliefs about abstinence and condoms and personal risk perception was conducted in all schools. Students in the intervention group were exposed for a 1-hour-and-45-minute-long in-class peer sexual health intervention. Students in the control schools were exposed to a 1-hour-long in-class peer water purification intervention. A follow-up assessment of students was conducted after the intervention. Logistic regression analyses were conducted to determine whether significant differences between intervention and control groups emerged at follow-up. Relative to students in the control group, knowledge was higher and normative beliefs about abstinence and condoms were significantly more positive among students in the intervention schools. Students in the intervention schools also had a higher personal risk perception of acquiring HIV than students in control schools. These findings show that a school-based peer sexual health intervention implemented in Zambia was effective in increasing knowledge, positive normative beliefs about abstinence and condoms, and personal risk perception.

Sustaining and broadening intervention impact: a longitudinal randomized trial of 3 adolescent risk reduction approaches.

OBJECTIVE: To determine whether the addition of a parental monitoring intervention (Informed Parents and Children Together [ImPACT]) alone or with "boosters" could enhance (either broaden or sustain or both) the effect of a small group, face-to-face adolescent risk reduction intervention Focus on Kids (FOK). METHODS: A longitudinal, randomized, community-based cohort study was conducted of 35 low-income, community-based, in-town settings. A total of 817 black youths aged 12 to 16 years at baseline were studied. After completion of baseline measures, youths were randomized to receive a face-to-face intervention alone (FOK only), a face-to-face intervention and a parental monitoring intervention (FOK plus ImPACT), or both of the above plus boosters (FOK plus ImPACT plus boosters). Risk and protective behaviors were assessed at 6 and 12 months after intervention. RESULTS: At 6 months' follow-up, youths in families that were assigned to FOK plus ImPACT reported significantly lower rates of sexual intercourse, sex without a condom, alcohol use, and cigarette use and marginally lower rates of "risky sexual behavior" compared with youths in families that were assigned to FOK only. At 12 months after intervention, rates of alcohol and marijuana use were significantly lower and cigarette use and overall risk intention were marginally lower among FOK plus ImPACT youths compared with FOK only youths. With regard to the boosters delivered at 7 and 10 months, 2 risk behaviors--use of crack/cocaine and drug selling--were significantly lower among the youths who were assigned to receive the additional boosters compared with youths without the boosters. The rates of the other risk behaviors and intentions did not differ significantly. CONCLUSIONS: The results of this randomized, controlled trial indicate that the inclusion of a parental monitoring intervention affords additional protection from involvement in adolescent risk behaviors 6 and 12 months later compared with the provision of an intervention that targets adolescents only. At the same time, the results of the present study do not provide sufficient evidence that booster sessions further improve targeted behaviors enough to include them in a combined parent and youth intervention.

Improving safety-restraint use by children in shopping carts: evaluation of a store-based safety intervention.

OBJECTIVE: Approximately 20,700 children who are < 5 years old are treated in US hospital emergency departments annually for shopping cart-related injuries. The objective of this study was to evaluate the effectiveness of an in-store intervention to increase the use of restraints in shopping carts by children who are < 5 years old. METHODS. The study intervention consisted of greeters at the store entrance who encouraged the use of appropriate shopping cart restraints plus the use of a small cash coupon incentive. The study used a preintervention and postintervention design with an untreated "control" group. Three stores served as intervention stores, and 4 stores served as nonintervention stores. Trained study personnel conducted the observations unobtrusively in all 7 stores simultaneously, recording the status of children's restraint use in the shopping cart as caregivers approached store checkout areas. The main outcome measure of the study was the change in the proportion of children who were < 5 years old, riding in a shopping cart, and restrained correctly. RESULTS: There were a total of 967 observations, 57% of which were in the 4 nonintervention stores and 43% of which were in the 3 intervention stores. There were 442 observations on the baseline day and 525 on the follow-up day. Interrater reliability was good. Overall, among the 761 cases in which a shopping cart was used, 38% of children were transported in the shopping cart seat with the restraint off or used improperly, and 24% were seated with the restraint used correctly. In the 4 nonintervention stores, the percentage of children who were in shopping carts and restrained correctly increased from 19% at baseline to 31% during the follow-up observation period 1 week later. In the 3 intervention stores, the percentage of correct restraint use among children in shopping carts went from 15% at baseline to 49% after the intervention during the second observation period. The change in correct restraint use among children in shopping carts in intervention stores was significantly greater than that in nonintervention stores. CONCLUSIONS: A safety intervention, consisting of a $2 incentive coupon plus greeters at the store entrance who encouraged the use of appropriate shopping cart restraints, significantly increased the correct use of restraints among young children who rode in shopping carts. The correct use rate increased to 49% in stores with this modest intervention. However, half of the young children in shopping carts remained unrestrained or restrained incorrectly. Higher rates of correct restraint use may occur with a more comprehensive and sustained shopping cart safety intervention. Shopping cart designs that seat children close to the floor and that do not rely on caregiver behavior change and vigilance for injury protection also should be implemented and evaluated as a passive strategy to prevent shopping cart-related injuries to young children.

Physician-prompting statin therapy intervention improves outcomes in patients with coronary heart disease.

STUDY OBJECTIVE: To evaluate the effectiveness of a posthospital discharge intervention that prompted physicians to increase the use and effectiveness of statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) in patients with coronary heart disease (CHD). METHODS: Participants were 612 patients with CHD who were admitted to a coronary care unit. The control group (303 patients admitted from October 1-December 31, 1998) received no follow-up intervention. The intervention group (309 patients admitted fromJanuary 1-March 31, 1999) had follow-up letters sent or phone calls made to their primary care physicians with patient-specific recommendations concerning assessment of lipid profiles and statin therapy. Over a 2-year follow-up period, assessment of lipid profiles, use of therapy, and adverse clinical outcomes were compared between the control and intervention groups. RESULTS: At hospital discharge, there was no significant difference in the use of statins between the groups. At each reported follow-up interval, the percentages of patients having lipid profiles measured, being treated with a statin, receiving titrated dosages of a statin, and achieving low-density lipid (LDL) cholesterol goals set by the National Cholesterol Education Program (NCEP) were significantly greater in the intervention group compared with the control group (all p<0.05). At the end of the 2-year follow-up period, nearly three-fourths (72%) of the intervention group were receiving a statin, compared with 43% of the control group. In addition, 55% of the intervention group achieved their NCEP LDL goal, compared with only 10% of the control group. Recurrent myocardial infarction, hospitalization for myocardial ischemia, coronary revascularization, and cardiovascular mortality were significantly reduced in the intervention group compared with the control group (all p<0.05). CONCLUSION: A relatively simple physician-prompting intervention significantly increased assessment of lipid status, frequency of statin use, achievement of LDL treatment goals, and titration of lipid drug dosages. In addition, the improved use of statins significantly reduced adverse cardiovascular outcomes. This intervention tool should be more broadly applied in patient populations eligible to receive these agents.

Meta-analysis of interventions to improve drug adherence in patients with hyperlipidemia.

OBJECTIVE: To examine the results of meta-analyses addressing the net effect of tools and methods to enhance drug adherence in patients with hyperlipidemia. METHODS: We searched MEDLINE, International Pharmaceutical Abstracts (IPA), PsychLit, Educational Resource Information Clearinghouse (ERIC), and Excerpta Medica Database (EMBASE) databases (1996-2000) for randomized controlled trials of interventions to improve patients' adherence to drug regimens for hyperlipidemia. All trials selected had at least 10 subjects/group. Effect sizes, represented as the correlation coefficient, were calculated from Cohen's d and d'. Analysis of variance and the Q test were performed to evaluate statistical significance and heterogeneity. RESULTS: Of the 484 articles evaluated, only four met the criteria for inclusion. Multiple interventions or study samples were identified in two articles. Each intervention was counted as a separate study, yielding seven cohorts with a total of 3077 subjects. Behavioral interventions accounted for five cohorts (2915 subjects). No cohorts received solely educational interventions. Two cohorts, with a total of 162 subjects, received a combination of behavioral and educational interventions. Homogeneity of groupings and effect sizes were calculated for the overall grouping as well as for each type of intervention. Overall, the effect size for the data was 0.14 (95% confidence interval [CI] 0.10-0.17) and the data were homogenous (Q = 7.36, df = 4, p = 0.29). The effect size for the behavioral interventions was 0.14 (95% CI 0.11-0.18, Q = 5.25, df = 4, p = 0.26). For interventions that combined behavioral and educational components, the effect size was 0.03 (CI -0.13-0.18, Q = 0.204, df = 1, p = 0.65). CONCLUSIONS: The interventions evaluated had little impact on drug adherence. More studies are needed to assess how to improve drug adherence in patients with hyperlipidemia.

Failure to maintain the benefits of home-based intervention in adolescents with poorly controlled type 1 diabetes.

OBJECTIVE: To determine whether a 6-month home-based intervention program in adolescents with poorly controlled diabetes improves metabolic control and whether benefits are maintained after the intervention. RESEARCH DESIGN AND METHODS: Adolescents with a mean HbA1c of > 9.0% over the preceding 12 months received either routine care in a diabetes clinic and an ambulatory intervention for 6 months (n = 37) or routine care only (n = 32). A diabetes educator provided monthly home visits and weekly phone contact to educate and support the adolescents in setting goals for insulin adjustment, blood glucose monitoring, and target blood glucose range. There was no systematic change in the frequency of insulin injections. After the intervention, there was a 12-month follow-up when the intervention and control groups both received only routine care. Outcome measures were HbA1c and Diabetes Knowledge Assessment (DKN). RESULTS: During the intervention, mean HbA1c fell (baseline: 11.1 +/- 1.3%, 6 months: 9.7 +/- 1.6%; P = 0.0001) and mean knowledge scores increased (P = 0.0001) in the intervention group but not in control subjects. However, this improvement in HbA1c and increase in knowledge was not maintained in the intervention group at 12- and 18-month follow-up assessments. Parents' knowledge scores also improved significantly from baseline levels in the intervention group at 6 and 12 months (P = 0.001, P = 0.005, respectively). CONCLUSIONS: An ambulatory program improves metabolic control and knowledge in adolescents with poorly controlled type 1 diabetes; however, it is effective only while the intervention is maintained.

An economic analysis of interventions for diabetes.

The objective of this article is to stratify interventions for diabetes according to their economic impact. We conducted a review of the literature to select articles that performed a cost-benefit analysis for 17 widely practiced interventions for diabetes. A scale for categorizing interventions according to their economic impact was defined. The 17 interventions were classified as follows: 1) clearly cost-saving, 2) clearly cost-effective, 3) possibly cost-effective, 4) non-cost-effective, or 5) unclear. Clearly cost-saving interventions included eye care and pre-conception care. Clearly cost-effective interventions included nephropathy prevention in type 1 diabetes and improved glycemic control. Possibly cost-effective interventions included nephropathy prevention in type 2 diabetes and self-management training. Non-cost-effective interventions were not identified. Interventions with unclear economic impact included case management, medical nutrition therapy, self-monitoring of blood glucose, foot care, blood pressure control, blood lipid control, smoking cessation, exercise, weight loss, HbA1c measurement, influenza vaccination, and pneumococcus vaccination. Widely practiced interventions for patients with diabetes can be clearly cost-saving and clearly cost-effective. These practices are attractive from both a medical and an economic perspective.

Change and 1-year maintenance of nutrient and food group intakes at a 12-week worksite dietary intervention trial for men at high risk of coronary heart disease.

We examined how dietary habits (i.e., intake of nutrients and food groups) were changed by intervention and how once adopted diets were maintained thereafter using the data of a 12-wk worksite dietary intervention trial for men at high risk of coronary heart disease (i.e., hypercholesterolemia, hyperglycemia, and/or overweight). Dietary habits were assessed pre- and post-intervention and 1 y follow-up points using a self-administered diet history questionnaire. The intervention method was a brief individual counseling based on the results of a pre-intervention assessment and a weekly distribution of newsletters. At the pre- and post-intervention points, a control group selected from the workers was used for comparison. The Keys score, and the changes in intake of saturated fatty acids (SFA), monounsaturated fatty acid, total fat, and cholesterol (the decrease), as well as dietary fiber, potassium, calcium, and iron (the increase) were significantly different between the intervention (n = 63) and control (n = 123) groups (p < 0.05). The changes were almost maintained with little recidivism at the 1 y follow-up point in the intervention group (i.e., for the decrease in SFA and Keys score, p < 0.001). The decrease in serum cholesterol level expected from the change in Keys score and body weight, taking possible regression to the mean into consideration, was almost identical to and slightly greater than (18%) those observed at the post-intervention and 1 y follow-up points, respectively. The results suggest that the favorable changes in dietary habits adopted during an intervention period were almost maintained for the subsequent 1 y period.

A systematic literature review of the effectiveness of non-pharmacological interventions to prevent wandering in dementia and evaluation of the ethical implications and acceptability of their use.

OBJECTIVES: To determine the effectiveness and cost-effectiveness of non-pharmacological interventions (excluding subjective barriers) in the prevention of wandering in people with dementia, in comparison with usual care, and to evaluate through the review and a qualitative study the acceptability to stakeholders of such interventions and identify ethical issues associated with their use. DATA SOURCES: Major electronic databases were searched up until 31 March 2005. Specialists in the field. REVIEW METHODS: Selected studies were assessed and analysed. The results of two of the efficacy studies that used similar interventions, designs and outcome measures were pooled in a meta-analysis; results for other studies which reported standard deviations were presented in a forest plot. Owing to a lack of cost-effectiveness data, a modelling exercise could not be performed. Four focus groups were carried out with relevant stakeholders (n = 19) including people with dementia and formal and lay carers to explore ethical and acceptability issues in greater depth. Transcripts were coded independently by two reviewers to develop a coding frame. Analysis was via a thematic framework approach. RESULTS: Ten studies met the inclusion criteria (multi-sensory environment, three; music therapy, one; exercise, one; special care units, two; aromatherapy, two; behavioural intervention, one). There was no robust evidence to recommend any non-pharmacological intervention to reduce wandering in dementia. There was some evidence, albeit of poor quality, for the effectiveness of exercise and multi-sensory environment. There were no relevant studies to determine the cost-effectiveness of the interventions. Findings from the narrative review and focus groups on acceptability and ethical issues were comparable. Exercise and distraction therapies were the most acceptable interventions and raised no ethical concerns. All other interventions were considered acceptable except for physical restraints, which were considered unacceptable. Considerable ethical concerns exist with the use of electronic tagging and tracking devices and physical barriers. Existing literature ignores the perspectives of people with dementia. The small number of participants with dementia expressed caution regarding the use of unfamiliar technology. Balancing risk and risk assessment was an important theme for all carers in the management of wandering. CONCLUSIONS: There is no robust evidence so far to recommend the use of any non-pharmacological intervention to reduce or prevent wandering in people with dementia. High-quality studies, preferably randomised controlled trials, are needed to determine the clinical and cost-effectiveness of non-pharmacological interventions that allow safe wandering and are considered practically and ethically acceptable by carers and people with dementia. Large-scale, long-term cohort studies are needed to evaluate the morbidity and mortality associated with wandering in dementia for people both in the community and in residential care. Such data would inform future long-term cost-effectiveness studies.

[A comparison of interventions recorded in nursing notes between acute and subacute stage after a cerebrovascular accident].

PURPOSE: This study aimed to: 1) determine the core nursing interventions, and 2) compare acute interventions with subacute interventions recorded in the nursing notes of patients with cerebrovascular accidents (CVA). METHODS: The nursing records covering the first 10 days of 30 patients with a CVA who were admitted from January to December 2004 at C University Hospital in Korea were examined. Data was collected using the nursing interventions classification (NIC) from January to April 2005. Finally, data analysis was carried out using mean, SD, and paired t-test according to domains, classes, and interventions. RESULTS: The most frequent nursing intervention at both stage was "Neurologic monitoring". There were differences in interventions belonging to the "Physiological: complex," "Behavioral," "Safety," and "Health system" domains between the acute and subacute stages. The frequency of interventions belonging to the "Immobility management," "Neurological management," "Tissue perfusion management," "Patient education," "Risk management," "Health system mediation," and "Information management" classes at the acute stage was higher compared to the subacute stage. CONCLUSIONS: This study found out that nurses relatively recorded more nursing interventions during the acute stage hence the unsuccessful documentation of the subacute stage particularly in describing the specific nursing interventions at this stage.

Evaluation of motivationally tailored vs. standard self-help physical activity interventions at the workplace.

PURPOSE: This study compares the efficacy of a self-help intervention tailored to the individual's stage of motivational readiness for exercise adoption with a standard self-help exercise promotion intervention. DESIGN: Interventions were delivered at baseline and 1 month; assessments were collected at baseline and 3 months. SETTING: Eleven worksites participating in the Working Healthy Research Trial. SUBJECTS: Participants (n = 1559) were a subsample of employees at participating worksites, individually randomized to one of two treatment conditions. INTERVENTION: Printed self-help exercise promotion materials either (1) matched to the individual's stage of motivational readiness for exercise adoption (motivationally tailored), or (2) standard materials (standard). MEASURES: Measures of stage of motivational readiness for exercise and items from the 7-Day Physical Activity Recall. RESULTS: Among intervention completers (n = 903), chi-square analyses showed that, compared to the standard intervention, those receiving the motivationally tailored intervention were significantly more likely to show increases (37% vs. 27%) and less likely to show either no change (52% vs. 58%) or regression (11% vs. 15%) in stage of motivational readiness. Multivariate analyses of variance showed that changes in stage of motivational readiness were significantly associated with changes in self-reported time spent in exercise. CONCLUSIONS: This is the first prospective, randomized, controlled trial demonstrating the efficacy of a brief motivationally tailored intervention compared to a standard self-help intervention for exercise adoption. These findings appear to support treatment approaches that tailor interventions to the individual's stage of motivational readiness for exercise adoption.

Randomized trial of a brief dietary intervention to decrease consumption of fat and increase consumption of fruits and vegetables.

PURPOSE: This study tested the efficacy of a computer-assisted counseling intervention to reduce diet-related cancer risk. DESIGN: Randomized controlled trial. SUBJECTS: Healthy women HMO members (n = 616) aged 40 to 70. INTERVENTION: Participants were randomly assigned to nutrition intervention or an attention-control intervention unrelated to diet. Intervention consisted of two 45-minute counseling sessions plus two 5- to 10-minute follow-up telephone contacts. Counseling sessions included a 20-minute, interactive, computer-based intervention using a touchscreen format. Intervention goals were reducing dietary fat and increasing consumption of fruit, vegetables, and whole grains. MEASURES: Twenty-four hour diet recalls and the Fat and Fiber Behavior Questionnaire (FFB). RESULTS: Four-month follow-up data were collected from 94% of the intervention participants and 91% of the controls. Testing with a multivariate general linear models analysis showed improvements on all dietary outcome variables. Compared to the control, intervention participants reported significantly less fat consumption (2.35 percentage points less for percentage of energy from fat), significantly greater consumption of fruit and vegetables combined (1.04 servings per day), and a significant reduction in a behavioral measure of fat consumption (.24 point change in the FFB). CONCLUSIONS: These 4-month results are comparable to several other moderate-intensity studies showing that, in the appropriate circumstances, moderate-intensity dietary interventions can be efficacious. Study limitations include the short follow-up period and the use of self-reported outcome measures.

Implementation of participatory ergonomics intervention in construction companies.

OBJECTIVES: The effectiveness of the implementation of participatory ergonomics intervention to reduce physical work demands in construction work was studied. METHODS: In a cluster randomized controlled trial, 10 bricklaying companies were randomly assigned either to an intervention group (N = 5) or a control group (N = 5). The intervention strategy used a consultant-guided six-step approach in which company stakeholders participated. Bricklayers and bricklayers' assistants in the intervention group (N = 65) and the control group (N = 53) were followed for 6 months, and their use of four ergonomic measures (adjusting work height when picking up bricks and mortar, adjusting work height for bricklaying at a wall side, mechanizing brick transport, and mechanizing mortar transport) was compared. The use of the ergonomic measures was assessed from worksite observations and questionnaires at baseline and after 6 months. The workers' and employers' behavioral change phases were determined by questionnaires and interviews, respectively. Performance indicators were assessed for the intervention from the researchers' observations during the implementation process and through questionnaires completed by the workers. RESULTS The strategy had no statistically significant effect on the use of any of the four ergonomic measures, at either the cluster or the individual level. None of the companies in the intervention group passed through all six steps of the intervention. Process outcomes suggest that the ability to use ergonomic measures increased. In bricklaying, self-efficacy and skills to adapt the work height on the scaffolding improved significantly. CONCLUSIONS: The intervention did not lead to greater use of ergonomic measures in bricklaying or the transport of materials. Performance indicators of intervention and the corresponding behavioral change phases of stakeholders can help to detect essential elements of such intervention.

The effects of quality improvement interventions on inhospital mortality after acute myocardial infarction.

OBJECTIVE: To evaluate the effects of quality improvement interventions on inhospital mortality after admission for acute myocardial infarction (AMI). DESIGN: Before-and-after study (with concurrent controls) based on hospital discharge data from a routinely maintained, administrative database. SETTING: All Queensland public hospitals, July 1991 - June 1999. STUDY POPULATION: Patients with AMI admitted through the emergency department. INTERVENTION: Development and promulgation of clinical practice guidelines at one hospital, combined with regular audit and feedback, commencing November 1995. MAIN OUTCOME MEASURES: Inhospital mortality (adjusted for age, sex and comorbidities) for four-year periods before (1991-92 to 1994-95) and after (1995-96 to 1998-99) initiation of quality improvement interventions. RESULTS: Before the intervention, the adjusted odds ratio (OR) for inhospital death at the intervention hospital was about the same as at other public hospitals (adjusted OR, 0.99; 95% CI, 0.80-1.24), but was more than 40% lower after the intervention (adjusted OR, 0.59; 95% Cl, 0.45-0.78). After the intervention, the risk of death at the intervention hospital was lower compared with hospitals with cardiologists as admitting practitioners (adjusted OR, 0.63; 95% CI, 0.48-0.83), with onsite revascularisation facilities (adjusted OR, 0.66; 95% CI, 0.49-0.88), and with large numbers (> or = 250 per year) of annual admissions of patients with AMI (adjusted OR, 0.72; 95% CI, 0.54-0.97). CONCLUSIONS: Quality improvement interventions lower the risk of inhospital death in patients with AMI. Implementation of such interventions in all hospitals may confer a risk of death lower than that achieved by admitting all patients under the care of cardiologists, or to hospitals with revascularisation facilities or a high volume of admissions of patients with AMI.

Documentation of pharmacist interventions in a decentralized unit dose system.

The purpose of this study was to justify the increased costs of providing decentralized pharmacy service by defining therapeutic interventions as they relate to improved patient care and by documenting cost savings generated by decentralized pharmacist interventions. Data were collected on a daily basis from information provided by the decentralized pharmacists using a daily worksheet. The various interventions were then categorized as cost-saving interventions and therapeutic interventions. Decentralized pharmacist interventions do provide important therapeutic interventions as well as cost-effective interventions. The total cost-saving interventions in 1989 was $126,509 and this included the automatic drug conversions. The pharmacists also provided 2506 therapeutic interventions.
