“…The muscles have the following functions (Kendall et al 1993): flexor pollicis longus (FPL) flexes the interphalengeal joint of the thumb while the extensor pollicis brevis (EPB) extends the metacarpophalangeal joint of the thumb; the anterior deltoid (AD) flexes and medially rotates the shoulder joint whereas the lateral deltoid (LD) abducts the joint. Previous studies of pipetting have also examined the FPL (Asundi et al 2005;Lintula and Nevala 2006;Sormunen and Nevala 2013), EPB (Lee and Jiang 1999;Asundi et al 2005), AD (Feng et al 1997;Rempel et al 2011) and LD (Feng et al 1997;Lee and Jiang 1999).…”

“…In relation to pipette work, it has been reported that UE muscle activity and/or posture are affected, depending on conditions such as the forceful demand of the pipette operation (Fredriksson 1995;Lu et al 2008), the design of the pipette (Lee and Jiang 1999;Asundi et al 2005;Lintula and Nevala 2006;Sormunen and Nevala 2013), the pipette task (Lee and Jiang 1999;Asundi et al 2005;Lu et al 2008) and the arm support type (Feng et al 1997;Rempel et al 2011). Pipette design has also been shown to affect the ratings of hand, arm and grip comfort (Lichty et al 2011).…”

This cross-sectional study compared the usability of pharmaceutical packages to determine the critical factors involved in packages with different opening mechanisms. Four packaging types (a bottle with a screw cap, a box with a pill plate, disposable plastic droppers with a container and a jar with a hinge cap) were evaluated by 45 women (nurses, older women and women with rheumatoid arthritis). Usability was evaluated for subjective measures related to the ease of opening and for objective measures related to the time needed to open the packaging, electrical muscular activity (electromyography, EMG) and ranges of motion of the upper extremities.Of the arthritic women, 13% were unable to open the screw-cap bottle, and 20% did not succeed in opening the plastic dropper packaging. Everyone else, except one older woman handling the plastic dropper packaging, managed to open all the packages. Regarding the ease of opening, the participants gave the plastic dropper packaging the lowest rating (p < 0.001). The arthritic women used greater relative biomechanical strain while opening the screw cap bottle and the box with pill plate compared with the other participants (p < 0.05), with the relative muscular strain in the forearm varying by 29-40% for the maximal EMG activity and the relative range of motion in the wrist being 70-90% of the maximal range of motion.These findings revealed both subjectively and objectively measured features on the usability of pharmaceutical packages. The comprehensibility of the opening mechanism and the ease of handling the package should be considered when user-friendly products are being created.Package: A = bottle with a screw cap, B = box and its pill plate, C = disposable plastic dropper and its container, D = plastic container with a hinge cap.Values are means (standard deviations) of the ratings on a visual analogue scale (0 =

“…7,12 Opening limitations have been indicated to prevent patients from accessing medications and result in their noncompliance, prohibiting the prescribed regimen from achieving maximal therapeutic benefit. 7,13 Additionally, injuries associated with difficulty in opening medications have been reported. The accident and emergency divisions of hospitals in the United Kingdom reveal that over 94,000 people, that is, 66,889 non-medicine packaging and 27,425 medicine packaging-related accidents/injuries were admitted in a year.…”

Consumer experiences and perception with reclosable pharmaceutical child resistant closures in Ghana, West Africa

Child resistant closures (CRCs) are an effective deterrent in preventing inadvertent poisoning in young children. Nevertheless, investigations since their debut have shown that users in different parts of the world do not embrace this safety package due to their opening mechanism. In this study, consumers who have interacted with pharmaceutical CRCs in Ghana within the West African sub‐region were interrogated to assess their experiences and perception. The assessments centred on consumer attitudes towards using CRCs generally, as well as their understanding of and importance for CRCs, the types that are available, observed cases of unintended medicinal child poisoning, ease of opening and injuries/accidents caused by them. The two observed CRCs used in the region were push and turn and squeeze and turn closures, with the former being the most popular. Regardless of educational level, consumers within the region had little understanding of how CRCs worked and how important they were. Due to their imprecise instructions and unpleasant opening mechanisms, CRCs were generally assessed by consumers as being challenging to open. Consumers unable to open CRCs employed their teeth, knives and sharp objects, resulting in injuries and casualties such as cuts and scratches. To maintain safe containment and limit children's exposure to medications, consumers identified CRCs as their top choice for pharmaceutical packaging. In conclusion, consumers oppose changing the design of CRCs but advocate for better opening instructions and pharmacist education for correct use.
