Psychological responses to the needle-free Medi-Jector or the multidose Disetronic injection pen in human growth hormone therapy.

What Was Tested

Researchers studied Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in this randomized controlled trial publication.

A questionnaire was used to assess psychological responses such as non-compliance, opinion on ease of preparation, affective responses to administration and local side-effects, as well as overall preference.

Why It Was Studied

The Medi-Jector is a needle-free injection device that can deliver growth hormone subcutaneously through jet injection.

Previously, all subjects had received growth hormone therapy with commercially available multidose injection pens.

Who Took Part

According to the abstract, 18 children were involved.

The age groups tagged for this paper are children, teenagers and adults, both men and women.

How the Study Was Run

The design is described as randomized and crossover.

The children were allocated by chance, so the Exogenous HGH, sermorelin & older GHRPs (why they're passed over) group and the comparison group should start out alike.

Each person switched between Exogenous HGH, sermorelin & older GHRPs (why they're passed over) and the comparison at some point, usually with a gap in between.

What Was Measured

PubMed files the paper under topics including Chi-Square Distribution, Human Growth Hormone, Injections, Jet, Pain, Patient Compliance, Patient Satisfaction and Statistics, Nonparametric.

What This Means in Plain Language

The paper is a randomized and crossover study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in 18 children.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The publication is from 1998 (Acta paediatrica (Oslo, Norway : 1992)), a journal based in Norway.
