Predicting and Preventing Manual Handling Injuries

Background:

• Mixed methods study - association between decisions and MH injuries (Nurses)

• Health Belief Model – explain and predict health behaviour

• Epidemiological approach

The Health Belief Model …

To adopt a health message individuals must perceive it to be a health threat

i.e. a serious problem to which they are susceptible

Injury Epidemiology claims …

“as injuries are predictable they are also preventable … and …

to a large extent society (hospitals) chose the injury rate it has”

(Christoffel et al 1999)

Injury Epidemiology uses …

• Host-agent-environment triad to identify problems, interaction and where to direct interventions

Environment (physical, social)

Agent = mechanical energy

(vector, vehicle)

Host (human)

Injury Epidemiology uses …

The Haddon Matrix to analyse injury and plan interventions

Host(human)

Agent(vehicle vector)

Environment (social

physical)

Pre-event

Event

Post-event

Injury Epidemiology uses …

A structured approach to injury prevention

Haddon’s 10 countermeasures

Passive or Active

Engineering, Education, Enforcement

Aim of this presentation …

• To consider the findings of manual handling research

• From an injury prevention framework perspective

Mixed Methods Study

• Focus groups (x5)• Case-control questionnaire (n=368)

– Analysed injuries (n=82)– Analysed Comments (n=90)

MH decision and their effect on injury

RN/EN in clinical positions

Triangulation …

• Combines research methodologies• To strengthen results• Improve accuracy and interpretation• Identifies consistent, convergent results• Correlations demonstrate strong

relationship

• Host – those most at risk, i.e. who to target

• Environment – hazards to eliminate from the injury area

• Agent - what delivers the energy

Host (those most at risk)

• Did not perceived MH as a health threat

• Pre-injury less likely to aches/pain related to MH

• Post-injury

↑ awareness of susceptibility to injury

Safer MH practice

Ongoing exercise programs

Agent (transfers energy)

• Patients – primary agent (vector) 74%

(↓mobility, ↑weight, AMS, v sick, anxious)

• Equipment – 17% (n=14) incidents

faulty equip (n=5)

equip only (n=9)

Environment (hazards to eliminate)

Physical

workspace

Social

staffing numbers

time limits / workload

expectations (problem in 21% injuries)

Injury prevention interventions• By Haddon’s countermeasures (x10)

• If passive or active

• By approach: education, engineering, enforcement

• If in the pre-event or event phase

#1: prevent the initial creation of the hazard

• Cannot avoid patients – but can avoid routine manual lifting

• No-lift, minimal lift, safe lift, zero-lift etc. policies

Requires enforcement (pre/event - passive)

Requires equipment (pre/event)

Requires education (pre)

• Substantial evidence base

#2 reduce the amount of energy in the hazard

• Reduce the energy transferred by using MH equipment (event - active)

e.g. Hoists, slide sheets, etc.

• Equipment alone ↓ risk factors

• More effective in multifaceted approach

• Substantial evidence ↓injuries ↓costs

#3 prevent release of a hazard that already exists

Contain the hazard by:• Assess hazards and how to manage them

(algorithms, Red Dots)(pre/event - active)• Dedicated wards for specific pt – spinal,

bariatric etc. (pre - passive) • Close beds if staffing unsafe (pre - passive)• Some evidence (assessment), dedicated

wards – cautious recommendation

#4 modify the rate of spatial distribution of the hazard

Change how the hazard is delivered• Optimal floors - minimise resistance to

wheels (pre - passive)• Large wheels (pre - passive)• Share the load – work as a team (event -

active)

• Substantial evidence

#5 separate in time and space, the hazard from that to be protected

Separation prevents transfer of energy• Dedicated lift teams – remove 95% of

routine MH from nurses (event - passive)

- Are a team, use equipment with MH their priority

-↓ MH injuries to nurses + v few injuries to lift teams personal

• Substantial evidence (from USA)

#6 separate the hazard (by a material barrier) from that which is to be protected

Form a barrier between hazardous equipment and the nurse (pre – passive)

• Remove faulty or inappropriate MH equipment and replace with appropriate equipment

• Automatic process to maintain equipment

Provision/maintenance required by MH codes

#7 modify relevant basic qualities of the hazard

Amend unsafe aspects of hazards (equip + environ) • Equipment: “state-of-the-art” (pre-event,

passive) • Work areas: de-clutter bed space, > space

for bariatric pt and their equipment - modify existing or design new facilities, flooring. (pre-event, active and passive)

#7 modify relevant basic qualities … cont

• Social environment: work expectations, safety climate of organisation and the influence of manager/supervisor (event – active)

• Policy implemented at ward level, overseen by managers group to target with education

• Substantial evidence re influence of Mx

#8 make what is to be protected more resistant to damage from the hazard

Make nurses more resilient and better able to withstand MH (pre-event, active)

• Exercise - strengthens muscles and ↑ flexibility of trunk

• Short-term benefits (voluntary/mandatory, 40-60 mins, x2/week for 3-12 months

• Substantial evidence

#9 begin to counter the damage done by the hazard

Managing the injury in a way that prevents further damage (post-event, active)• Best Practice - early aggressive managed

care, by a team led by occupational physician Includes: assessment, assurance, education, involves manager

• Substantial evidence, international best practice, legal requirement

#10 stabilise, repair and rehabilitate the object of the damage

Aims to return injured persons to work ASAP and undertake rehabilitation in the workplace if possible • Psychosocial issues related to the injury (yellow

flags) may obstruct return. Must be identified and resolved in conjunction with the manager

• Physical demands assessed modified duties

• Successful programs for general MSD and LBP include exercise programs

Planning injury prevention

• Injuries are predictable

• Occur as the result of a chain of events

• Intervention are planned to interrupt the chain and address identified risk factors

• Principles are used to maximise prevention

Injury epidemiology principles1. Active or passive interventions: prefers passive

- will always be effective

2. Single or mixed interventions: prefer mixed -injuries have multiple causes with multiple prevention opportunities. Must address host-agent-environment in pre/event/post phases

3. Prioritise the most effective intervention rather than relying on education to change behaviour

Injury epidemiology principles

4. Education efficacy increased if supported by:

-legislation /policy (enforcement)

-passive interventions in environment

-modification of psychosocial environment

Results of this study• Host - did not perceive manual handling as

a heath threat. Problem - active interventions may not be employed

• 10 agent - patients with obvious constraints. Problem - cannot change pt have to change approach

• 10 environment – social expectation to take risks to complete work. Problem -training and policy ignored

Implications for Practice:• Multifaceted interventions are more effective• Training/education are part of multifaceted

interventions (need infrastructure and social support to use skills/knowledge)

• Develop + implement a safety climate• Educate managers/supervisors

• Substantial evidence
