Interface pressure measurements: Visual interpretation of pressure maps with MS clients

PURPOSE

Pressure mapping systems provide useful information for pressure care assessment. Healthcare professionals tend to rely upon their colour-coded pressure maps to assist clinical decision-making, based on ranking these from best to worst pressure distribution. The current study investigated whether such ranking is an appropriate method of assessment when compared to use of the numerical output of average and maximum pressure values (mmHg), yielded by the system.

METHOD

This community-based correlational study involved 27 multiple sclerosis clients (15 wheelchair users; 12 non-wheelchair users). Pressure maps were recorded on each participant's current seating surface and on six pressure reducing cushions, using the Force Sensing Array pressure mapping system. Outcome measures included (1) rank order of pressure maps based on visual interpretation by two occupational therapists, (2) average pressure (mmHg) and (3) maximum pressure (mmHg). Visual ranking of the colour-coded pressure maps was correlated with average and maximum pressure values for each map.

RESULTS

Correlations between visual ranking of maps and maximum pressures were high for six out of seven surfaces (p < 0.05) for non-wheelchair users; however, they were much less between average pressures and visual interpretation for the same cohort. Similarly, correlations between visual ranking of maps and average pressures for wheelchair users was minimal and was only noted as being high (p < 0.05) on two surfaces when considering maximum pressures and visual interpretation.

CONCLUSIONS

This study contests the usefulness of the visual ranking of pressure maps in interpreting interface pressures with MS clients, especially with wheelchair users. Visual interpretation of pressure maps by clinicians may be useful in eliminating inappropriate support surfaces from a selection, or those that display easily identifiable 'extremes' of pressure values. Clinicians need to incorporate and interpret the numerical data as well as pressure maps when conducting their assessment and making provision.

Evaluation of a MS specialist nurse programme

BACKGROUND

Specialist nurses are being promoted as a means of improving the health care provided to people with multiple sclerosis (MS).

OBJECTIVES

To identify the impact of a programme of MS specialist nurses on MS health care provision and on the health and well-being of people with MS.

DESIGN

A quasi-experimental design comparing an intervention group in which new MS nurse posts were installed with a control group that had no MS nurse posts.

SETTING

Six neurological services in four English regions.

PARTICIPANTS

Seven hundred and fifty-three of the 1510 people invited to participate returned completed questionnaires at baseline. Follow-up of participants was 82% with 616 patients participating in the main outcome analysis.

METHOD

Data were collected prospectively before the appointment of the MS nurses and then at 12 and 24 months. Data were collected via a postal questionnaire comprising questions related to care processes (information provision and care quality) and health outcome measures, hospital admissions, MS complications, health-related quality of life (SF36) and disease impact (MS Impact Scale-29). Analysis repeated measures in CAT MOD for process variables and ANCOVA to longest follow-up for outcome measures.

RESULTS

Information provision was higher in the intervention group (68% (n=153) compared to 53% (n=98) at 24 months) but no significant improvement was observed in information provision through time compared to the control group. There was an increase in the availability of a contact person in the intervention group, at 24 months 83% (n=42) had a contact person compared to 44% in the control (p=0.01). The only significant finding in relation to MS complications was a reduction of 17% in the incidence of pressure ulcers in the intervention sites compared to a 3% reduction in the control (p<0.001). In relation to the disease and health-related quality of life measures, the intervention group showed a small but significant (p<0.05) worsening in the physical and symptom scales of the SF36 compared to the control (mean differences: physical function -2.81, CI -5.45 to -0.1; bodily pain -4.09, CI -7.2 to -0.9; general health -5.35, CI -8.1 to -2.5; and energy and vitality -2.82, CI -5.5 to -0.1). No differences were observed in relation to disease impact or psychosocial well-being, although a relative benefit in mental health (with a 7.8 point advantage on the SF36 mental health scale, p=0.04) was observed in some of the intervention sites for people with relapsing/remitting MS.

CONCLUSION

The specialist nurse programme was found to impact positively on the provision of MS-related health care. However, there was very limited evidence that the programme led to any improvements in disease-related problems, impact or health-related quality of life, These findings were in part explained by the inherent difficulties of measuring effects in evaluations of complex phenomena such as a nursing role. The deterioration observed in the intervention group on the physical outcome measures was explained by a selection bias in which people with worsening health were more likely to seek contact with a specialist nurse. It is contended that future research in this area may be better directed toward identifying specific interventions that nurses and other health professionals might employ in addressing the many problems confronting people with MS.

Impact of clinical nurse specialists in multiple sclerosis--synthesis of the evidence

BACKGROUND

Multiple sclerosis is a chronic neurological condition demanding a broad range of interventions and support. Multiple sclerosis nurse specialists are emerging as a leading force in providing care to this group of patients.

AIM

This review aimed to identify and synthesize the evidence on the role of clinical nurse specialists in meeting the care needs of people with multiple sclerosis.

METHODS

A systematic review of the literature addressing the role of the multiple sclerosis nurse specialist was undertaken. The review examined both the appropriateness and effectiveness of the multiple sclerosis nurse specialist role. The content of each item identified in the review was analysed, examining the structure, process and outcomes variables associated with the role. Materials containing an explicit methodology were critically appraised using established schedules and graded as strong, moderate or weak. The data were then synthesized in tables, thematically and using a quasi-judicial approach called the 'System of Reasoning'.

FINDINGS

Fifty-five items were examined and most (53%; n = 18) were descriptive in nature. There was insufficient evidence to demonstrate that the multiple sclerosis nurse role makes a difference to care. However, evidence was found to support current descriptions of the role - meaning? and there appeared to be a good fit between the role and the care needs of people with multiple sclerosis.

CONCLUSION

A systematic overview of the attributes of the multiple sclerosis nurse role is provided which should help service providers, nurses and other professionals consider how multiple sclerosis nurse specialists roles can contribute to the care of people with this condition. While there is little current evidence of effectiveness for the multiple sclerosis nurse specialist role, there is evidence for its appropriateness, although more rigorous primary research is required to test this.
