Outpatient use of oral rehydration solutions in Apache population: effect of instructions on preparation and
Insights
Mixing Oral Rehydration Solutions (ORS) at home accurately is crucial for pediatric care. Pre-marked containers significantly improve sodium concentration accuracy compared to written instructions alone, reducing risks associated with incorrect ORS preparation.
Area of Science:
- Pediatrics
- Public Health
- Infectious Disease
Background:
- Recent recommendations for 90 and 50 mmol/L sodium Oral Rehydration Solutions (ORS) in U.S. ambulatory children.
- Commercial availability of ORS in powder form necessitates home preparation.
- Limited U.S. data exist on home mixing accuracy and potential bacterial contamination of ORS.
Purpose of the Study:
- To evaluate the impact of different instructional methods on the accuracy of home-prepared ORS.
- To assess the influence of various instructions on bacterial contamination during ORS mixing.
- To investigate the role of pre-marked containers versus written instructions in ensuring correct sodium concentration.
Main Methods:
- Randomized controlled trial involving mothers/guardians preparing ORS at home.
- Four groups received varying combinations of written instructions and pre-marked containers.
- Home ORS samples were collected and analyzed for electrolyte content and bacterial contamination.
Main Results:
- Significantly lower mean sodium (Na+) concentrations were observed in ORS prepared without pre-marked containers.
- Groups without pre-marked containers showed mean Na+ concentrations of 82 +/- 13 (II) and 79 +/- 21 (IV) mmol/L.
- Groups with pre-marked containers achieved higher mean Na+ concentrations: 88 +/- 13 (I) and 92 +/- 14 (III) mmol/L (p < 0.01).
Conclusions:
- Pre-marked containers are essential for ensuring accurate home mixing of Oral Rehydration Solutions.
- Inaccurate ORS preparation, particularly low sodium concentration, poses a risk in pediatric care.
- Further research should address bacterial contamination alongside mixing accuracy in home-based ORS preparation.
Abstract:
Oral Rehydration Solutions (ORS) containing 90 and 50 mmol/L sodium have recently been recommended for use in ambulatory children in the U.S. These solutions are now marketed in powder form by some commercial companies. However, few data are available in the U.S. on the accuracy with which the solutions are mixed at home or on the bacterial contamination that may occur during mixing. We evaluated the effect of various forms of instructions on the occurrence of bacterial contamination and accuracy of mixing ORS at home by mothers of patients who were dispensed the dry ingredients of an ORS containing 90 mmol/L sodium at the U.S. Public Health Service Hospital, Whiteriver, Arizona. Patients were randomized to one of the four following groups: group I (23 patients) was given written instructions for mixing the solution along with a pre-marked container; group II (22 patients) was given written instructions only; group III (22 patients) was given a premarked container only; and group IV (19 patients) was given neither. All patients were given oral instructions in the preparation of ORS and were asked to refrigerate the reconstituted ORS. We collected samples of ORS at the patient's home 1 day after the clinic visit, to measure their electrolyte content and to identify any bacterial contamination. Mean Na+ concentrations were significantly lower in the ORS prepared by mothers/guardians in groups that were not given a premarked container [82 +/- 13 (II) and 79 +/- 21 (IV) mmol/L vs. 88 +/- 13 (I) and 92 +/- 14 (III) mmol/L; p less than 0.01].(ABSTRACT TRUNCATED AT 250 WORDS)
