Clinical effectiveness outcomes Anonymised linked data We used routine data from the Secure Anonymised Information Linkage (SAIL) databank64 to compare services (emergency, acute and primary care) delivered to patients across the spectrum of risk – between intervention and control phases. The SAIL databank includes routine Welsh hospital data on emergency admissions (ED data set), secondary care (Patient Episode Database for Wales) and general practice data. We derived PRISM risk scores from GP data and linked these to data on health service use for all study patients who did not dissent from the postal survey. Postal questionnaires We sent postal questionnaires to sampled patients at three points: at baseline, and at 6 and 18 months after initiating PRISM in the first study practice. The questionnaire comprised three validated tools: the adapted Client Service Receipt Inventory65 to estimate individual health service use; the Quality of Care Monitor (QCM66) to measure patient satisfaction; and the SF-1267 to measure patient-reported outcomes. We aimed to recruit samples of 800 patients stratified by risk level to complete the questionnaires at each time point (Table 12). This equated to around 70 patients per practice for screening at each time point. To ensure representation from the very small risk groups 3 and 4 (4. We excluded patients who were aged < 18 years or > 100 years, or had recently left a participating practice. NWIS undertook this sampling from their anonymised PRISM data set so that selected patients were identifiable only by their practices. Those practices then checked their lists of sampled patients to assess their suitability to receive questionnaires. They excluded patients who lacked the capacity, support or resilience to complete questionnaires. No additional patients were selected at this stage if patients were excluded. Participating practices then sent questionnaires packs (letter from GP, information sheet, consent form, questionnaire and business reply envelope), direct to approved patients. The letter asked patients to return completed questionnaires and consent forms direct to the study team. Practices sent a second pack to patients who had not responded to the first after 2 weeks. The two subsequent surveys followed the same approach. Practices checked that the original sampled patients were still alive and suitable to participate, and sent them follow-up questionnaires. NWIS then replaced each patient lost to follow-up by another patient of the same age, sex and risk level. We undertook primary analysis by treatment allocated.

Gastrointestinal Absorption of M agnesium FIGURE 4-5 Gastrointestinal absorption of dietary intake of magnesium (M g). The normal adult dietary intake of M g is 300 to 360 mg/d (12. Foods high in M g content include green leafy vegetables absorption of dietary magnesium (M g) (rich in M g-containing chlorophyll), legumes, nuts, seafoods, and meats. Dietary intake is Mg absorption % of intake the only source by which the body can replete M g stores. Net intesti- Site mmol/day mg/day absorption nal M g absorption is affected by the fractional M g absorption within a specific segment of intestine, the length of that intestinal segment, Stomach 0 0 0 Duodenum 0. These segments of intestine are rel- Ileum atively short, however, and the transit time is rapid. In the intact animal, most of the M g absorption occurs in the Colon 0. Secretions of the upper intestinal tract contain approximately 1 mEq/L of M g, whereas secretions from the lower intestinal tract con- tain 15 mEq/L of M g. In states of nausea, vomiting, or nasogastric suction, mild to moderate losses of M g occur. In diarrheal states, M g depletion can occur rapidly owing to both high intestinal secretion and lack of M g absorption [2,6,8–13]. In rats, the intestinal M g 10 absorption is related to the luminal M g concentration in a curvilin- ear fashion (A). This same phenomenon has been observed in humans (B and C). The hyperbolic curve (dotted line in B and C) 8 seen at low doses and concentrations may reflect a saturable tran- scellular process; whereas the linear function (dashed line in B and 6 C) at higher M g intake may be a concentration-dependent passive intercellular M g absorption. Alternatively, an intercellular process 4 that can vary its permeability to M g, depending on the luminal M g concentration, could explain these findings (see Fig. Two possible routes exist for the absorption of M g across intestinal epithelial cells: the transcel- Nucleus lular route and the intercellular pathway. Although a transcellular route has not yet been dem onstrated, its existence is inferred from several observations. N o large chem ical gradient Lumen Mg2+ exists for M g m ovem ent across the cell m em brane; however, a significant uphill electrical gradient exists for the exit of M g from cells. This finding suggests the existence and partici- A pation of an energy-dependent m echanism for extrusion of M g from intestinal cells.
