Evaluation of an interpersonal-psychotherapy-oriented childbirth education programme for Chinese first-time childbearing women: A randomised controlled trial

Objective

This study investigated the effects of an interpersonal-psychotherapy-oriented childbirth psychoeducation programme on postnatal depression, psychological well-being and satisfaction with interpersonal relationships in Chinese first-time childbearing women.

Method

A randomised, controlled trial was conducted in the maternity clinic of a regional hospital in China. The intervention was based on the principles of interpersonal psychotherapy, and consisted of two 90-min antenatal classes and a telephone follow-up within 2 weeks after delivery. One hundred and ninety-four first-time pregnant women were randomly assigned to the intervention group (n = 96) or a control group (n = 98). Outcomes of the study included symptoms of postnatal depression, psychological well-being and satisfaction with interpersonal relationships, which were measured by the Edinburgh Postnatal Depression Scale (EPDS), General Health Questionnaire (GHQ) and Satisfaction with Interpersonal Relationships Scale (SWIRS), respectively.

Results

Women receiving the childbirth psychoeducation programme had significantly better psychological well-being (t = −3.33, p = 0.001), fewer depressive symptoms (t = −3.76, p = 0.000) and better interpersonal relationships (t = 3.25, p = 0.001) at 6 weeks postpartum as compared with those who received only routine childbirth education.

Conclusion

An interpersonal-psychotherapy-oriented childbirth psychoeducation programme could be implemented as routine childbirth education with ongoing evaluation. Replication of this study with more diverse study groups, such as mothers with high risks to depression, those with multiple, complicated or multiparas pregnancies, would provide further information about the effects of the programme.     

Student nurses’ de-escalation of patient aggression: A pretest-posttest intervention study

Background

Experts recommend staff training to prevent and manage aggressive situations involving patients or their relatives. However, in many countries this subject is not covered in pre-registration nursing education. In addition, the evidence regarding its impact on practical placements remains weak.

Objective

This study examines the influence of an aggression management training programme for nursing students on their performance in de-escalating aggressive patients.

Design

Pretest-posttest within-and-between-groups design.

Setting

A School of Nursing in Germany.

Participants

Convenience sample out of six classes of nursing students at differing educational levels (10th to 28th month of nursing education, n = 78, mean age = 22).

Methods

In a cross-sectional and longitudinal two groups before and after design nursing students encountered two scenarios (A or B) with simulation patients. After completing the training, each student was confronted with the unknown other scenario. De-escalation experts from three German-speaking countries evaluated 156 video scenes using the De-escalating Aggressive Behaviour Scale (DABS), not knowing whether the videos had been recorded before or after the training. Mean values and statistical significance tests were computed to compare the results.

Results

The performance levels of students who had been trained rose significantly from 2.74 to 3.65 as measured by the DABS on a 5-point Likert scale (Wilcoxon test p < .001). The trained students managed scenario A significantly better than the untrained students (untrained 2.50, trained 3.70; Mann-Whitney-U-test p < .001,). Similar results were found for scenario B (untrained 3.01, trained 3.61; Mann-Whitney-U-test p < .001). No significant differences were found in the pretest results irrespective the students’ age or duration of previous nursing education.

Conclusions

Aggression management training is able to improve nursing students’ performance in de-escalating aggressive behaviour. A maturation-effect on the de-escalating performance due to general nursing education or age is unlikely.     

Design and Evaluation of a New Bladder Volume Monitor

Wang J, Hou C, Zheng X, Zhang W, Chen A, Xu Z. Design and evaluation of a new bladder volume monitor.

Objective

To introduce and evaluate a new implantable bladder volume monitor.

Design

Experimental study.

Setting

Animal laboratory.

Animals

Eight dogs.

Interventions

A coin-shaped permanent magnet was stitched onto the anterior bladder wall and a magnetic field sensor was fixed onto the lower abdominal external wall in 8 male dogs. The bladder was filled with sterile normal saline in consecutive steps of 25mL each from 0 to 200mL by a transurethral catheter.

Main Outcome Measure

Sensor readings were recorded after each step of bladder filling.

Results

The sensor baseline was set at 70° when the bladder was empty. After filling the bladders with 25, 50, 75, 100, 125, 150, 175, and 200mL saline water, the sensor readings were 74.6±0.9°, 79.6±1.2°, 84.5±0.9°, 90.1±0.8°, 95.5±1.1°, 101.8±2.1°, 110.5±2.9°, and 121.9±3.5°, respectively. Sensor readings were positively correlated with bladder volume (r=1; P<.01).

Conclusions

The design of a new bladder volume monitor that is made up of an external magnetic field sensor and an internal permanent magnet is reasonable and feasible. The new bladder volume monitor is simple in structure.     

Step length appears to be a strong discriminant gait parameter for elderly females highly concerned about falls: a cross-sectional observational study

Objective

To determine if gait parameters and the Timed Up and Go test can discriminate between elderly females with high and low concern about falls. Knowledge of these parameters could help in the development of rehabilitation programmes focused on the prevention of falls, fear of falling and functional decline.

Design

Cross-sectional, observational study.

Setting

Human motion laboratory.

Participants

One hundred and fifty-four elderly females (aged 64 to 83 years), divided into two groups based on their Falls Efficacy Scale International score: high concern (n = 81) and low concern (n = 73) about falls.

Main outcome measures

Eight gait parameters recorded with the GAITRite system and the Timed Up and Go test score.

Results

Factor 2 (composed of step length, gait velocity and Timed Up and Go mobility test) explained 20% of the variability of the data and was the only factor to discriminate between the groups, with 63% correct classifications. Step length proved to be the variable with the greatest discriminant ability, with a much higher discriminant coefficient (0.889) than the Timed Up and Go test (−0.369) and gait velocity (−0.268).

Conclusions

High concern about falls is primarily associated with decreased step length. Step length could be used as a screening tool to identify elderly women with low and high concern about falls in order to target these groups in a rehabilitation programme aimed to slow reduction in gait velocity and mobility.     

N-terminal pro-brain natriuretic peptide in cases with metabolic syndrome and its relationship with components of metabolic syndrome and left ventricular mass index

Objective

In this study we investigated N-terminal pro-brain natriuretic peptide (Nt-proBNP) levels in patients with metabolic syndrome (MetS) and its relationship between MetS components.

Methods

Thirty nine recently diagnosed MetS cases and 59 control cases were included in the present study. Left ventricular mass index (LVMI) was calculated and Nt-proBNP was determined.

Results

Both groups were similar in terms of age and sex. Body mass index were significantly higher in MetS than non-MetS. LVMI measurements were not different between MetS and control groups (p = 0.168). Nt-proBNP levels were similar in both groups (p = 0.954). There was a significant correlation between Nt-proBNP and LVMI, age, serum LDL- and HDL-cholesterol levels. Nt-proBNP was independently related with age (β = 0.357, p = 0.015) and LDL-cholesterol (β = − 0.255, p = 0.049) in the multivariate analysis.

Conclusions

Nt-proBNP levels don't have a significant increase in MetS. But there was a significant relationship between Nt-proBNP levels and age and LDL-cholesterol.     

The effect of sample storage on the reliability of thyroglobulin and thyroglobulin-antibody measurements

Objectives

To investigate how sample-storage alters thyroglobulin (Tg) and thyroglobulin-antibody (TgAb) immunoreactivity.

Design and methods

Tg and TgAb measurements at different storage-times and -temperatures.

Results

48-h-storage at 4-10 °C (but not 8 h at room temperature) increased Tg and decreased TgAb immunoreactivity by maximum + 23% and − 16%. 4-weeks-storage at − 17 to − 20 °C decreased both Tg and TgAb by max. 21-31%.

Conclusions

Storage of samples at 4-10 °C for > 24-48 h, or at − 17 to − 20 °C for > 2-3 weeks significantly alters Tg and TgAb immunoreactivity.     

The SAFE or SORRY? programme. part II: effect on preventive care

Background

Patient care guidelines are usually implemented one at a time, yet patients are at risk for multiple, often preventable, adverse events simultaneously.

Objective

The SAFE or SORRY? programme targeted three adverse events (pressure ulcers, urinary tract infections and falls) and was successful in reducing the incidence of these events. This article explores the process of change and describes the effect on the preventive care given.

Design

Separate data on preventive care were collected along the cluster randomised trial, which was conducted between September 2006 and November 2008.

Settings

Ten hospital wards and ten nursing home wards.

Participants

We monitored nursing care given to adult patients with an expected length of stay of at least five days.

Methods

The SAFE or SORRY? programme consisted of the essential recommendations of guidelines for pressure ulcers, urinary tract infections and falls. A multifaceted implementation strategy was used to implement this multiple guidelines programme. Data on preventive care given to patients were collected in line with these guidelines and the difference between the intervention and the usual care group at follow-up was analysed.

Results

The study showed no overall difference in preventive pressure ulcer measures between the intervention and the usual care group in hospitals (estimate = 6%, CI: −7-19) and nursing homes (estimate = 4%, CI: −5-13). For urinary tract infections, even statistically significantly fewer hospital patients at risk received preventive care (estimate = 19%, CI: 17-21). For falls in hospitals and nursing homes, no more patients at risk received preventive care.

Conclusion

Though the SAFE OR SORRY? programme effectively reduced the number of adverse events, an increase in preventive care given to patients at risk was not demonstrated. These results seem to emphasise the difficulties in measuring the compliance to guidelines. More research is needed to explore the possibilities for measuring the implementation of multiple guidelines using process indicators.     

Ankle positioning and knee perturbation affect temporal recruitment of the vasti muscles in people with patellofemoral pain

Objectives

To compare the temporal recruitment of the vastus medialis obliquus (VMO) and vastus lateralis (VL) during voluntary ankle movements and perturbed standing in people with patellofemoral pain, and to determine the effects of different reflex and voluntary postural exercise tasks on VMO facilitation.

Design

Repeated-measures design.

Participants

Twenty-three subjects with patellofemoral pain.

Interventions

Quadriceps reflex contraction in response to postero-anterior knee perturbations was measured with three crural muscle contraction conditions and three postural exercises (semi-squatting, tip-toeing and heel standing).

Main outcome measures

The electromyographic (EMG) onset time of the VMO and VL during each task was measured and compared across the different tasks.

Results

The mean EMG onset time of the VMO was later than that of the VL in the voluntary tasks such as tip-toeing (VMO 95.3 ms vs VL 36.4 ms, mean difference 58.9 ms, 95% confidence interval −33.7 to 151.5 ms), whereas earlier VMO activation was found in the perturbation tests such as toe standing (VMO 17.6 ms vs VL 22.9 ms, mean difference −5.3 ms, 95% confidence interval −25.3 to 14.7 ms).

Conclusion

These findings suggest the potential benefits of unexpected perturbation activities for facilitating VMO activation. The clinical applications of perturbation tasks in rehabilitation exercise programmes and the underlying mechanisms warrant further investigation.     

Evaluation of a nurse-led social rehabilitation programme for neurological patients and carers: An action research study

Background

Very few neurological rehabilitation programmes have successfully dealt with patients’ and relatives’ social needs. Furthermore, the nurses’ contribution in those programmes is poor or unclear.

Objectives

To determine the rationale, effectiveness and adequacy of a nurse-led social rehabilitation programme implemented with neurological patients and their carers.

Design

In this action research study Hart and Bond's experimental and professionalizing typologies were applied through Lewinian cycles. A social rehabilitation programme was planned, based on the results of an in-depth baseline assessment of the context and individual needs. The programme focused on increasing the level of acceptance/adaptation of the disease through verbal and written education, easing the discharge planning, and offering social choices based on the social assessment of individual needs and possibilities at home.

Settings

Two neurological wards of a hospital in Spain.

Participants

The programme evaluation included 27 nurses, and two groups of patients and relatives (control group = 18 patients and 19 relatives, intervention group = 17 patients and 16 relatives).

Methods

The two groups of patients and relatives were compared before and after discharge to determine the effectiveness of the programme. Socio-demographic forms, semi-structured interviews, participant observations, and validated scales to measure activities of daily living and social life were used, and data were analysed using content (QSR Nudist Vivo, v.2.0) and statistical (SPSS v. 13.0) analyses.

Results

The new programme resulted in social care being integrated in daily practice and developed knowledge about social rehabilitation. This had a positive impact on nurses’ attitudes. Patients and relatives had more realistic expectations and positive attitudes towards social life, and developed a wider variety of choices for social changes. Better adaptation, and more coping skills and satisfaction were achieved.

Conclusions

This rehabilitation programme was feasible and effective. Patients and relatives benefited from better understanding of the socialisation process, as a result of advancing nurses’ knowledge, experience and role in psychosocial care.     

The clinical learning environment and supervision instrument (CLES): validity and reliability of the Dutch version (CLES+NL)

Background

The clinical learning environment and supervision scale (CLES) is a valid and reliable tool that was developed to assess the quality of nursing students’ clinical placements.

Objectives

To obtain a reliable and valid Dutch version of the CLES that is in line with the Flemish culture and educational context.

Design

Scale validation study on data provided by a cross-sectional survey.

Settings

190 wards in 31 institutions for healthcare in Flanders, Belgium.

Participants

768 student nurses enrolled in the 3 year bachelor programme at University College Ghent, Faculty of Healthcare Vesalius.

Methods

Face and content validation was followed by data collection. Factor analysis was performed using varimax rotation. Subsequently, internal consistency reliability was tested on the total scale and its subdimensions using Cronbach's alpha.

Results

We gathered 768 questionnaires. Factor analysis revealed 5 subdimensions with an eigenvalue greater than 1, explaining 71.281% of the variance. The overall internal consistency and the consistency of the five subdimensions is high. Our data supports face, content and construct validity of the CLES + NL.

Conclusions

The CLES + NL is a valid and reliable instrument that can be used to evaluate the quality of nursing wards as learning environments in Flanders.     

Influence of reduction in the elution times on HPLC glycohaemoglobin results

Objectives

To compare HPLC methods with short and long elution times for HbA1c measurement in blood.

Methods

Comparison between G7-Tosoh (1.2 min); Bio-Rad-Variant-II-Turbo (1.3 min) and Arkray-HA-8160 (2.9 min).

Results

Passing-Bablok regression equations were: Y = 0.17 + 0.96X; Y = − 0.39 + 1.01X; Y = − 0.40 + 1.0X and the means of the differences using Bland-Altman Plot were 0.02; − 0.34; 0.32 for HA-8160/G7-Tosoh, HA-8160/Variant-II-Turbo and G7-Tosoh/Variant-II-Turbo, respectively.

Conclusions

Faster elution methods had no problems on reproducibility of results obtained by slower elution methods.     

Interactive effects of nurse-experienced time pressure and burnout on patient safety: A cross-sectional survey

Background

Global nursing shortages have exacerbated time pressure and burnout among nurses. Despite the well-established correlation between burnout and patient safety, no studies have addressed how time pressure among nurses and patient safety are related and whether burnout moderates such a relation.

Objectives

This study investigated how time pressure and the interaction of time pressure and nursing burnout affect patient safety.

Design-setting participants

This cross-sectional study surveyed 458 nurses in 90 units of two medical centres in northern Taiwan.

Methods

Nursing burnout was measured by the Maslach Burnout Inventory-Human Service Scale. Patient safety was inversely measured by six items on frequency of adverse events. Time pressure was measured by five items. Regressions were used for the analysis.

Results

While the results of regression analyses suggest that time pressure did not significantly affect patient safety (β = −.01, p > .05), time pressure and burnout had an interactive effect on patient safety (β = −.08, p < .05). Specifically, for nurses with high burnout (n = 223), time pressure was negatively related to patient safety (β = −.10, p < .05).

Conclusion

Time pressure adversely affected patient safety for nurses with a high level of burnout, but not for nurses with a low level of burnout.     

The effect of quantity of ice and size of contact area on ice pack/skin interface temperature

Objective

To determine the effect of quantity of ice and contact area on ice pack/skin interface temperature during a 20-minute cooling period.

Design

Repeated measures.

Setting

Laboratory setting in an educational institution.

Participants

Twenty healthy males aged between 18 and 22 years.

Interventions

An ice pack was applied to the right thigh with compression using an elastic bandage. The effects of three packs measuring 18 cm × 23 cm containing 0.3, 0.6 and 0.8 kg of ice, and one pack measuring 20 cm × 25 cm containing 0.6 kg of ice were compared.

Main outcome measure

The reduction in temperature at the ice pack/skin interface during 20-minute ice applications was monitored at 1-minute intervals.

Results

The application of 0.8-kg and 0.6-kg ice packs led to a significantly greater decrease in the interface temperature compared with the 0.3-kg ice pack [0.8 kg vs. 0.3 kg: −2.35 °C, 95% confidence interval (CI) of the difference −3.36 to −1.34 °C; 0.6 kg vs. 0.3 kg: −2.95 °C, 95% CI −4.07 to −1.83 °C]. No significant difference in temperature was found between the 0.6-kg and 0.8-kg ice packs (0.8 kg vs. 0.6 kg: 0.6 °C, 95% CI −0.12 to 1.32 °C, P > 0.05). The size of the contact area did not alter the degree of cooling significantly (difference between smaller and larger pack: 0.05 °C, 95% CI −0.93 to 1.03 °C, P > 0.05). The lowest temperature during ice application was reached after 8-9 minutes of cooling.

Conclusion

Application of an ice pack containing at least 0.6 kg of ice leads to a greater magnitude of cooling compared with application of a 0.3-kg ice pack, regardless of the size of the contact area. Thus, clinicians should consider using ice packs weighing at least 0.6 kg for cold treatment.     

Quality of closed chest compression on a manikin in ambulance vehicles and flying helicopters with a real time automated feedback

Context

Automated verbal and visual feedback improves quality of resuscitation in out-of-hospital cardiac arrest and was proven to increase short-term survival. Quality of resuscitation may be hampered in more difficult situations like emergency transportation. Currently there is no evidence if feedback devices can improve resuscitation quality during different modes of transportation.

Objective

To assess the effect of real time automated feedback on the quality of resuscitation in an emergency transportation setting.

Design

Randomised cross-over trial.

Setting

Medical University of Vienna, Vienna Municipal Ambulance Service and Helicopter Emergency Medical Service Unit (Christophorus Flugrettungsverein) in September 2007.

Participants

European Resuscitation Council (ERC) certified health care professionals performing CPR in a flying helicopter and in a moving ambulance vehicle on a manikin with human-like chest properties.

Interventions

CPR sessions, with real time automated feedback as the intervention and standard CPR without feedback as control.

Main outcome measures

Quality of chest compression during resuscitation.

Results

Feedback resulted in less deviation from ideal compression rate 100 min⁻¹ (9 ± 9 min⁻¹, p < 0.0001) with this effect becoming steadily larger over time. Applied work was less in the feedback group compared to controls (373 ± 448 cm × compression; p < 0.001). Feedback did not influence ideal compression depth significantly. There was some indication of a learning effect of the feedback device.

Conclusions

Real time automated feedback improves certain aspects of CPR quality in flying helicopters and moving ambulance vehicles. The effect of feedback guidance was most pronounced for chest compression rate.     

Differential features of burden between spouse and adult-child caregivers of patients with Alzheimer's disease: An exploratory comparative design

Background

Research into burden among spouse and adult-child caregivers of patients with Alzheimer's disease has generated contradictory results as regards the group which suffers the greatest burden and the factors underlying any differences.

Objectives

The aim of the present study was to identify and compare the factors associated with caregiver burden among spouse and adult-child caregivers.

Design

Cross-sectional analytic study.

Settings

All clinical subjects had been referred on an out-patient basis to the Memory and Dementia Assessment Unit of the Santa Caterina Hospital in Girona (Spain).

Participants

Data were collected from 251 patients and their caregivers, 112 with spouse and 139 with adult-child caregivers.

Methods

The association between caregiver burden and the socio-demographic and clinical variables of both patients and caregivers was analysed, the results being compared for spouse vs. adult-child caregivers. Burden was analysed using a multivariate linear regression including all the variables for the two groups of caregivers.

Results

The results show greater burden among adult-child caregivers (p < .05), who experience more feelings of guilt (p < .001). In both groups the behavioural and psychological symptoms of patients were correlated with burden (p < .001). Living with the patient has a notable influence on burden among adult children (p < .001). Husbands, wives, daughters and sons, in this order, showed increasing levels of burden (p < .05) and progressively worse mental health (p < .01). However, the correlations between burden and mental health were strongest in daughters (p < .001).

Conclusion

The differences in burden between spouse and adult-child caregivers were not associated with age, physical health or clinical factors of the patients. Overall burden was greater among adult-child caregivers, especially those who lived with the patient and who had other family duties. Feelings of guilt were associated with not living with the patient, and there was a strong correlation between burden and mental health. These results support the hypothesis that spouses regard caregiving as part of their marital duties, whereas for adult children such tasks imply an important change in their lifestyle.     

Prognosis of Limitations in Activities in Osteoarthritis of the Hip or Knee: A 3-Year Cohort Study

van Dijk GM, Veenhof C, Spreeuwenberg P, Coene N, Burger BJ, van Schaardenburg D, van den Ende CH, Lankhorst GJ, Dekker J, on behalf of the CARPA Study Group. Prognosis of limitations in activities in osteoarthritis of the hip or knee: a 3-year cohort study.

Objective

To describe the course of limitations in activities in elderly patients with osteoarthritis (OA) of the hip or knee over a follow-up period of 3 years, and to identify prognostic factors of the course of limitations in activities, focusing on body functions, comorbidity, and cognitive functioning.

Design

A longitudinal cohort study with 3 years of follow-up. Measurements were conducted annually. Statistical analyses included t tests, univariate regression analyses, and multivariate regression analyses.

Setting

Rehabilitation centers and hospitals (Departments of Orthopedics, Rheumatology, and Rehabilitation) in The Netherlands.

Participants

Patients (N=237) with hip or knee OA.

Interventions

Not applicable.

Main Outcome Measures

Patient-perceived change, self-reported limitations in activities measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and observed limitations in activities (timed walking test). Prognostic factors: demographic data, clinical data, body function (pain, muscle strength, range of motion [ROM]), comorbidity, and cognitive functioning (cognitive decline, memory, attention).

Results

Self-reported limitations in activities measured by the WOMAC improved slightly after 3-year follow-up. In knee OA, reduced ROM at 1-year follow-up (β=.120), increased pain at 1-year follow-up (β=−.177), and higher morbidity count (β=−.180) predicted worsening of self-reported limitations in activities. In hip OA, reduced ROM at 1-year follow-up (β=.201 for hip external rotation and β=.144 for knee extension), increased pain at 1-year follow-up (β=−.134), higher morbidity count (β=−.220), or the presence of moderate to severe cardiac disease (β=−.214) and poorer cognitive functioning (β=.181) predicted worsening of self-reported limitations in activities. Performance-based limitations in activities measured by the timed walking test did not change after 3 years of follow-up. In knee OA, decreased muscle strength at 1-year follow-up (β=−.272) and higher morbidity count (β=.199) predicted worsening of performance-based limitations in activities. In hip OA, better ROM (β=.182), higher morbidity count (β=.232), or the presence of moderate to severe cardiac and eye-ear-nose-throat disease (β=.210 and β=.188, respectively) and older age (β=.355) predicted worsening of performance-based limitations in activities.

Conclusions

Overall, at the group level, limitations in activities of patients with OA of the hip or knee recruited from hospitals and rehabilitation centers seem fairly stable during the first 3 years of follow-up. However, at the level of individual patients, considerable variation occurs. Prognostic factors for worsening of limitations in activities include increased pain, reduced ROM, and decreased muscle strength at 1-year follow-up; higher morbidity count; and to a lesser extent poor cognitive functioning.     

The effect of a physiotherapy education compared with a non-healthcare education on the attitudes and beliefs of students towards functioning in individuals with back pain: An observational, cross-sectional study

Objectives

To investigate the difference in attitudes: (1) between first and fourth year physiotherapy students towards functioning in individuals with back pain; and (2) between physiotherapy students and non-healthcare students towards functioning in individuals with back pain.

Design

Observational, cross-sectional study.

Setting

Glasgow Caledonian University, Scotland, UK.

Participants

First year physiotherapy (n = 61) and non-healthcare students (n = 61), and fourth year physiotherapy (n = 62) and non-healthcare students (n = 62).

Main outcomes

All participants completed the Health Care Providers’ Pain and Impairment Relationship Scale (range 15 to 105). This questionnaire measures attitudes towards functioning in individuals with back pain.

Results

Fourth year physiotherapy students had more positive attitudes towards functioning in individuals with back pain than first year physiotherapy students [57.4 vs 66.6 (mean difference −9.2, 95% confidence interval −12.2 to −6.1, P < 0.01)]. Similarly, fourth year non-healthcare students had more positive attitudes towards functioning in individuals with back pain compared with first year non-healthcare students [69.2 vs 65.3 (mean difference −3.9, 95% confidence interval −7.2 to −0.5, P = 0.03)]. Physiotherapy students had more positive attitudes than non-healthcare students in the first year [66.6 vs 69.2 (mean difference −2.6, 95% confidence interval −5.5 to 0.4, P = 0.08)] and the fourth year [57.4 vs 65.3 (mean difference −7.9, 95% confidence interval −11.4 to −4.4, P < 0.01)] of study.

Conclusion

These findings suggest that physiotherapy education brings about positive student attitudes towards functioning in individuals with back pain. This may be partly attributable to receiving a university degree education, but would appear to be further enhanced by specifically receiving a physiotherapy degree. This may facilitate students to become more evidence-based practitioners following qualification.     

Metronome improves compression and ventilation rates during CPR on a manikin in a randomized trial

Aim

We hypothesized that a unique tock and voice metronome could prevent both suboptimal chest compression rates and hyperventilation.

Methods

A prospective, randomized, parallel design study involving 34 pairs of paid firefighter/emergency medical technicians (EMTs) performing two-rescuer CPR using a Laerdal SkillReporter Resusci Anne^® manikin with and without metronome guidance was performed. Each CPR session consisted of 2 min of 30:2 CPR with an unsecured airway, then 4 min of CPR with a secured airway (continuous compressions at 100 min⁻¹ with 8-10 ventilations/min), repeated after the rescuers switched roles. The metronome provided “tock” prompts for compressions, transition prompts between compressions and ventilations, and a spoken “ventilate” prompt.

Results

During CPR with a bag/valve/mask the target compression rate of 90-110 min⁻¹ was achieved in 5/34 CPR sessions (15%) for the control group and 34/34 sessions (100%) for the metronome group (p < 0.001). An excessive ventilation rate was not observed in either the metronome or control group during CPR with a bag/valve/mask. During CPR with a bag/endotracheal tube, the target of both a compression rate of 90-110 min⁻¹ and a ventilation rate of 8-11 min⁻¹ was achieved in 3/34 CPR sessions (9%) for the control group and 33/34 sessions (97%) for the metronome group (p < 0.001). Metronome use with the secured airway scenario significantly decreased the incidence of over-ventilation (11/34 EMT pairs vs. 0/34 EMT pairs; p < 0.001).

Conclusions

A unique combination tock and voice prompting metronome was effective at directing correct chest compression and ventilation rates both before and after intubation.     

Pulmonary rehabilitation for chronic obstructive pulmonary disease: a pilot study evaluating a once-weekly versus twice-weekly supervised programme

Objectives

To compare the effectiveness of a once-weekly supervised pulmonary rehabilitation programme with a standard twice-weekly format.

Design

Randomised trial of equivalency.

Setting

Pulmonary rehabilitation service of a primary care trust delivered at two physiotherapy outpatient departments.

Participants

Thirty patients with chronic obstructive pulmonary disease.

Outcome measures

Primary outcomes were the Incremental Shuttle Walking Test (ISWT), Endurance Shuttle Walking Test (ESWT) and St George's Respiratory Questionnaire (SGRQ), assessed at baseline and at completion of the supervised programme. Secondary outcomes were home-exercise activity, attendance levels and patient satisfaction with the programme.

Interventions

The once-weekly group (n = 15) received one supervised rehabilitation session per week, and the twice-weekly group (n = 15) received two sessions per week, both for 8 weeks, together with a home-exercise plan.

Results

After pulmonary rehabilitation, the groups showed similar improvements in exercise tolerance (median values: ISWT once-weekly 60 metres, twice-weekly 50 metres; ESWT once-weekly 226 seconds, twice-weekly 109 seconds). However, for health-related quality-of-life, the once-weekly group's score did not change (SGRQ 0), whereas an improvement was seen for the twice-weekly group (SGRQ 3.7). The number of home-exercise sessions and attendance levels were similar between the groups. Patient satisfaction with both formats was high and almost identical between the groups.

Conclusions

This pilot provides data to inform a larger study and shows that the methodology is feasible. The findings suggest that once-weekly supervision may be capable of producing equivalent improvements in exercise tolerance as a twice-weekly programme, but the health-related quality-of-life outcome appeared to be poorer for once-weekly supervision.
