Evaluation domain

Description

Data collection methods

Reach

Recruitment of patients

Proportion of patients recruited of those eligible. (Quantitative data)

Screening log: recorded all eligible patients approached and recruited during study period.

Intervention delivery

Delivery to patients

Quantity and quality of intervention delivery; i.e.: Were patients’ diets prescribed in accordance with EOF pathway? Did patients receive pre-operative nutrition handout and verbal nutrition-related messages? How long were the nutrition-related messages and what did they entail? (Quantitative and qualitative data)

Chart audits and direct observations to assess whether patients were prescribed diets in accordance with pathway, and if not, reasons why recorded. Chart audit determined whether preoperative nutrition handout was delivered. Direct observationsa assessed whether doctors provided nutrition-related messages and the content covered.

Delivery to HCPs

Quantity and quality of intervention delivery; i.e.: How many staff attended sessions? What topics were covered? How long were sessions? (Quantitative data)

Intervention delivery log: recorded staff who attended information sessions, duration of each session, materials used, and content covered.

HCP responses and interactions

Staff responses to and interactions with intervention; mediators; and unexpected pathways and consequences. (Qualitative data)

Semi-structured interviews were undertaken by a research assistant at end of study period.

Context

Anything external to the intervention that may act as a barrier or facilitator to implementation or moderate its effects. (Qualitative data)

A description of the study site and participants was considered in the interpretation of findings.

Adaptations

Any tailoring, changes or adaptations made to the original intended intervention. (Qualitative data)

Field notes were kept by the lead author with details of any adaptations/ changes made to the original intervention.

Causal assumptions/ mechanisms

Data informing proposed causal assumptions/mechanisms sourced from process and outcome data (described within this table); as well as existing literature.
